BACKGROUND: The purpose of this study was to examine two techniques for Carpal Tunnel Syndrome, mini-Open Carpal Tunnel Release (mini-OCTR) and Endoscopic Carpal Tunnel Release (ECTR), to compare their therapeutic efficacy. METHODS: Sixteen patients who underwent mini-OCTR in palmar incision and 17 patients who underwent ECTR in the wrist crease incision were included in the study. All patients presented preoperatively and at 1, 3, and 6 months postoperatively and were assessed with the Visual Analogue Scale (VAS) and the Disabilities of Arm, Shoulder and Hand Score (DASH). We also assessed the pain and cosmetic VAS of the entire affected hand or surgical wound, and the patient's satisfaction with the surgery. RESULTS: In the objective evaluation, both surgical techniques showed improvement at 6 months postoperatively. The DASH score was significantly lower in the ECTR group (average = 3 months: 13.6, 6 months: 11.9) than in the mini-OCTR group (average = 3 months: 27.3, 6 months: 20.6) at 3 and 6 months postoperatively. Also, the pain VAS score was significantly lower in the ECTR group (average = 17.1) than in the mini-OCTR group (average = 36.6) at 3 months postoperatively. The cosmetic VAS was significantly lower in the ECTR group (average = 1 month: 15.3, 3 months: 12.2, 6 months: 5.41) than in the mini-OCTR group (average = 1 month: 33.3, 3 months: 31.2, 6 months: 24.8) at all time points postoperatively. Patient satisfaction scores tended to be higher in the ECTR group (average = 3.3) compared to the mini-OCTR group (average = 2.7). CONCLUSIONS: ECTR in wrist increase incision resulted in better pain and cosmetic recovery in an early postoperative phase compared with mini-OCTR in palmar incision. Our findings suggest that ECTR is an effective technique for patient satisfaction.

ABSTRACT

Objectives

To report up to 3-year safety and effectiveness of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis from a postmarketing surveillance study.

Methods

Patients enrolled previously completed 24 weeks of CZP in the 24-week postmarketing surveillance study. Adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes were 28-joint Disease Activity Score with erythrocyte sedimentation rate and European Alliance of Associations for Rheumatology response. Week 24–156 safety and Week 0–52 effectiveness data are reported here.

Results

A total of 781 patients were enrolled, with 735 and 376 patients evaluated for safety and effectiveness, respectively. Within the safety set, 17.8% (131/735) of patients reported ADRs; 9.4% (69/735) reported serious ADRs. Among patients with history of respiratory, thoracic, and mediastinal disorders, 38.4% (28/73) reported ADRs. The most frequent ADRs were infections and infestations (11.8%; 87/735); skin and subcutaneous tissue disorders (1.9%; 14/735); respiratory, thoracic, and mediastinal disorders (1.6%; 12/735). Mean 28-joint Disease Activity Score with erythrocyte sedimentation rate reduced from 4.6 (Week 0) to 2.8 (Week 52). At Week 52, 51.8% (161/311) of patients achieved European Alliance of Associations for Rheumatology Good response.

Conclusions

The long-term safety and effectiveness of CZP in the real-world setting in Japan were consistent with previously reported data; no new safety signals were identified.

ABSTRACT

Objectives

Late-onset rheumatoid arthritis (LORA), which has been increasing in recent years, lacks evidence for initial treatment. Japanese rheumatology experts recognized this gap and addressed it by developing consensus statements on the first clinical application of LORA.

Methods

These statements were created following an introductory discussion about treatment fundamentals, which included a review of existing literature and cohort data. The steering committee created a draft, which was refined using a modified Delphi method that involved panel members reaching a consensus. The panel made decisions based on input from geriatric experts, clinical epidemiologists, guideline developers, patient groups, and the LORA Research Subcommittee of the Japan College of Rheumatology.

Results

The consensus identified four established facts, three basic approaches, and six expert opinions for managing LORA. Methotrexate was recommended as the primary treatment, with molecular-targeted agents being considered if treatment goals cannot be achieved. An emphasis was placed on assessing the lives of older patients due to challenges in risk management and methotrexate accessibility caused by comorbidities or cognitive decline.

Conclusions

The experts substantiated and refined 13 statements for the initial treatment of LORA. To validate these claims, the next is to conduct a registry study focusing on new LORA cases.

We retrospectively investigated the mid-term outcomes of arthroplasty using the AVANTA silicone implant for thumb metacarpophalangeal (MCP) joints with boutonniere deformity in patients with rheumatoid arthritis (RA). This study involved 36 thumbs of 33 RA patients with a mean follow-up period of 5.1 years (range, 2.0-13.3). Postoperatively, the mean extension was significantly increased and the mean flexion was significantly decreased (p<0.001, p<0.001, respectively), resulting in the mean arc of range of motion (ROM) shifting in the direction of extension after surgery. Implant fracture was observed in 10 thumbs (28%), and 4 of these (11%) underwent revision surgery. The survivorship with implant fracture and revision surgery as endpoints were 73.4% and 91.8% at 5 years, respectively. The preoperative arc of ROM and the postoperative flexion range of the implant-fracture group were significantly greater than those in the no-implant-fracture group (p=0.039, 0.034, respectively). These results suggest the importance of patient education and careful rehabilitation to prevent excessive flexion. Overall, the AVANTA silicone implant showed a relatively high rate of implant fracture at our institute.

BACKGROUND: Corrective osteotomy for intra-articular malunion is a challenging procedure. However, recent advancements, including patient-matched instruments created on the basis of preoperative computer simulation, enable accurate intra-articular correction. We hypothesized that intra-articular corrective osteotomy using patient-matched instruments for the treatment of distal radial intra-articular malunion would reduce intra-articular deformity and restore wrist function at 12 months of follow-up. METHODS: This prospective study included 12 patients with distal radial intra-articular malunion who underwent intra-articular corrective osteotomy external to the joint using patient-matched instruments. The primary end point was the maximum step-off on the articular surface of the distal radius, measured with use of computed tomography (CT), with an expected postoperative value of ≤1.5 mm. The secondary end points included the gap of the articular surface; range of motion; grip strength; pain evaluated using a visual analog scale (VAS); patient satisfaction; Disabilities of the Arm, Shoulder and Hand (DASH) score; and Patient-Rated Wrist Evaluation (PRWE) score. A mean postoperative step-off of ≤1.5 mm for the primary end point was assessed with use of the 1-sample t test. The secondary end points were assessed with use of the Dunnett multiple comparison test. RESULTS: The average step-off significantly improved from 3.75 ± 1.04 mm preoperatively to 0.51 ± 0.40 mm at the 52-week postoperative follow-up and was maintained within 1.5 mm. The average wrist and forearm range of motion, VAS score, grip strength, DASH score, and PRWE score significantly improved. Eleven patients were either very satisfied or satisfied with their outcomes. CONCLUSIONS: The use of patient-matched instruments could contribute to improving postoperative outcomes of intra-articular corrective osteotomy procedures involving the distal radius. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Background: It is not clear whether rehabilitation after surgery for trigger finger is effective. The aim of this study was to reveal its effectiveness for trigger finger. Methods: This study was a randomized, controlled trial that included patients who underwent operations for trigger fingers. The patients in the rehabilitation group had postoperative occupational therapy (OT) for 3 months, while the patients in the control group were not referred for rehabilitation but received advice for a range of motion exercises. We evaluated the severity of trigger finger, Disability of Arm-Shoulder-Hand (DASH) score, pain-visual analogue scale (VAS), grip strength, whether they gained a full range of motion (ROM), and complications before and after surgery. Results: Finally, 29 and 28 patients were included in the control and rehabilitation groups, respectively. At final follow-up, the DASH score, grip strength, and ROM were significantly improved in the rehabilitation group compared to that preoperatively. At final follow-up, pain was significantly improved in both groups from that preoperatively. There were no significant differences in the results, including the DASH score, grip strength, ROM and pain-VAS between the control and rehabilitation groups at the final follow-up. Subgroup analysis showed that there is a significant difference in the DASH score of patients doing housework or light work and those with a duration of symptoms &gt;12 months between the control and rehabilitation groups at the final follow-up.

Total wrist arthroplasty is a challenging procedure for wrist joints severely destroyed by rheumatoid arthritis. The most common postoperative complication of total wrist arthroplasty is the loosening of the carpal component. Revision surgeries for failed total wrist arthroplasties can be complicated owing to severe bone loss and concomitant soft-tissue problems. Here we report a case (68-year-old woman with a history of rheumatoid arthritis for 24 years) of severe aseptic loosening of semi-constrained total wrist arthroplasty and its salvage surgery. During the primary arthroplasty procedure, severe instability at the second through fifth carpometacarpal joints was observed, and arthrodesis of these joints was required. The radiographs obtained nine months after surgery showed loosening of the carpal component. Subsequently, she suffered a stroke, resulting in a loss of follow-up, and higher stress was loaded on her upper extremities during standing and walking. In the radiograph taken at her revisit 25 months after the primary surgery, the subsidence of the carpal component progressed, and loosening of the radial component was observed. Total wrist arthrodesis was performed using a bulk bone allograft of the femoral head, combined with a penetrating Wrist Fusion Rod®. Rapid bone union was achieved without soft tissue irritation. We conclude that wrist arthrodesis with a bulk bone allograft combined with an intramedullary nail is a reasonable option for failed total wrist arthroplasty.

ABSTRACT

Objective

We retrospectively reviewed the records of rheumatoid arthritis (RA) patients who underwent orthopaedic surgery to examine the influence of the perioperative use of Janus kinase (JAK) inhibitors on early postoperative complications.

Patients and Methods

Thirty-two patients with RA under disease control with JAK inhibitors who underwent 49 orthopaedic procedures were included in the study. Patient records after surgery were investigated for surgical site infection (SSI), delayed wound healing (DWH), a flare-up of the disease, preoperative and postoperative absolute lymphocyte counts (ALCs), venous thromboembolism, and other postoperative complications.

Results

JAK inhibitors were continued during the perioperative period in 31 procedures. In the remaining 18 procedures, JAK inhibitors were discontinued perioperatively with a mean discontinuation period of 2.4 days. No instances of SSI were identified in any patient during at least 90 days’ follow-up, while DWH was seen in one patient. Disease flare-up was noted in two patients after 3 and 9 days of discontinuation of JAK inhibitors, respectively. The ALCs significantly decreased on postoperative Day 1 (P &amp;lt; .0001), and there was a significant correlation between pre- and post-one-day ALCs (r = 0.75, P &amp;lt; .0001).

Conclusion

JAK inhibitors seem to be safe during the perioperative period of orthopaedic surgery.

BACKGROUND: In chronic musculoskeletal pain patients, detection of sarcopenia is of significant clinical interest. Phase angle, which can be measured through bioelectrical impedance analysis (BIA), can detect sarcopenia; however, the evidence in chronic musculoskeletal pain patients is limited. This study aimed to assess the relationship between phase angle and sarcopenia in patients with chronic musculoskeletal pain. Our hypothesis was that phase angle would be a useful indicator to identify sarcopenia in patients with chronic musculoskeletal pain. METHODS: A total of 190 patients (51 men and 139 women) with chronic musculoskeletal pain were included in this retrospective cross-sectional study. Patient data of backgrounds, numeric rating scale score for pain, skeletal muscle index, and phase angle assessed using BIA were retrospectively reviewed. Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia criteria 2019. RESULTS: A total of 51 patients (26.7%), including 10 men (19.6%) and 41 women (29.5%), were diagnosed with sarcopenia. Phase angle, sarcopenia-related factors, age, and body mass index (BMI) differed significantly in patients with and without sarcopenia. On multiple logistic regression analysis, the prevalence of sarcopenia was significantly correlated with phase angle and BMI. The areas under the curve exhibited high accuracy in discriminating sarcopenia in men and moderate accuracy in both sexes and in women. CONCLUSIONS: Phase angle may be a valid discriminator of sarcopenia in patients with chronic musculoskeletal pain.

ABSTRACT

Objectives

We examined the relationship between the Japanese version of Patient-Rated Elbow Evaluation (PREE-J) and other established subjective and objective outcome measures in Japanese patients with rheumatoid arthritis (RA) who underwent total elbow arthroplasty (TEA).

Materials and Methods

This study involved 46 elbows of 40 RA patients. We collected clinical data 1 year after surgery, including the PREE-J, the Mayo Elbow Performance Score (MEPS), Disability of the Arm, Shoulder, and Hand (DASH), and Hand20. The correlation and responsiveness to PREE-J were evaluated compared with other outcome measures preoperatively and postoperatively.

Results

Almost all outcome measures were improved significantly after surgery. Preoperative PREE-J was significantly correlated with preoperative DASH, Hand20, and MEPS. Interestingly, postoperative PREE-J did not correlate with postoperative MEPS. Multiple regression analyses revealed that preoperative grip strength [B = −0.09; 95% confidence interval (95% CI) −0.17 to −0.01, p = 0.03] and preoperative Hand20 (B = 0.31, 95% CI 0.03–0.58, p = 0.03) were significant factors that might influence the postoperative PREE-J.

Conclusions

The PREE-J was shown to correlate well with other preoperative outcome measures among the RA patients included in the current study. The postoperative PREE-J after TEA was influenced by the preoperative grip strength and function of the hand.

Chronic pain coexists with disability, anxiety, depression, and sleep disturbances, which are factors of pain chronicity in the fear-avoidance model. Self-efficacy for managing pain plays a protective role against pain chronicity. For chronic pain sufferers, social support from caregivers is important. However, such caregivers face enormous physical and mental burdens. This study aimed to assess how self-efficacy and factors related to the fear-avoidance model affect caregiver burden. Participants were 135 chronic pain patients and their caregivers who visited our outpatient pain special clinic. In clinical assessments, numeric rating scale (NRS), pain catastrophizing scale (PCS), hospital anxiety and depression scale (HADS), Athens insomnia scale (AIS), pain disability assessment scale (PDAS), pain self-efficacy questionnaire (PSEQ) for the patients and Zarit Burden Interview (ZBI) for their caregivers were evaluated. Participants were divided into 2 groups (L group ZBI < 24 points and H group ZBI ≥ 24 points) and compared. Regression analyses were conducted to identify factors correlated with the ZBI scores. Compared to L group, H group showed significantly higher NRS and HADs depression scores, and lower PSEQ scores. In univariate regression analysis, ZBI scores were significantly correlated with NRS, PCS, HADS anxiety, HADS depression, PDAS and PSEQ. Multiple linear regression analysis revealed that ZBI scores were significantly correlated with PSEQ. The caregivers who perceived high caregiver burden had significantly higher patients' pain intensity, depression, and lower self-efficacy than those who perceived low caregiver burden. Caregiver burden correlated with the pain intensity, pain catastrophizing, anxiety, depression, disability, and self-efficacy of chronic pain patients. Among these factors, self-efficacy was the most negatively correlated with caregiver burden. Treatments focused on increasing self-efficacy for managing pain have the potential to reduce caregiver burden.

Tendons and ligaments are jointed to bones via an enthesis that is essential to the proper function of the muscular and skeletal structures. The aim of the study is to investigate the effect of mechanical stress on the enthesis. We used ex vivo models in organ cultures of rat Achilles tendons with calcaneus including the enthesis. The organ was attached to a mechanical stretching apparatus that can conduct cyclic tensile strain. We made the models of 1-mm elongation (0.5 Hz, 3% elongation), 2-mm elongation (0.5 Hz, 5% elongation), and no stress. Histological evaluation by Safranin O staining and Toluidin Blue and Picro Sirius red staining was conducted. Expression of sex-determining region Y-box 9 (Sox9), scleraxis (Scx), Runt-related transcription factor 2 (Runx2), and matrix metalloproteinase 13 (Mmp13) were examined by real-time polymerase chain reaction and immunocytochemistry. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate biotin nick end-labeling and live/dead staining and was conducted for evaluation of the apoptosis and cell viability. The structure of the enthesis was most maintained in the model of 1-mm elongation. The electronic microscope showed that the enthesis of the no stress model had ill-defined borders between fibrocartilage and mineralized fibrocartilage, and that calcification of mineralized fibrocartilage occurred in the model of 2-mm elongation. Sox9 and Scx was upregulated by 1-mm elongation, whereas Runx2 and Mmp13 were upregulated by 2-mm elongation. Apoptosis was inhibited by low stress. The results of this study suggested that 1-mm elongation can maintain the structure of the enthesis, while 2-mm elongation promotes degenerative changes.

OBJECTIVES: Early sarcopenia detection using screening tools, such as SARC-F and SARC-CalF, has been proven reliable. However, the relationship between chronic musculoskeletal pain with sarcopenia is unknown. This study assessed sarcopenia morbidity as well as the reliability of sarcopenia screening with SARC-F and SARC-CalF in patients with chronic musculoskeletal pain. METHODS: Overall, 172 patients with chronic musculoskeletal pain were included in this cross-sectional study. All participants completed the SARC-F, SARC-CalF, numeric rating scale (NRS), and pain disability assessment scale (PDAS) assessments. Sarcopenia was diagnosed using the Asian Working Group for Sarcopenia criteria 2019. Correlations between SARC-F and SARC-CalF scores and each measured variable were evaluated using univariate and multiple linear regression analyses. A receiver operating characteristic curve analysis was conducted, and reliabilities of SARC-F and SARC-CalF scores for diagnosing sarcopenia were compared. RESULTS: Thirty-nine patients were diagnosed with sarcopenia. Among these, 10 patients were <65 years old, and 29 were >65 years old. Both SARC-F and SARC-CalF scores significantly correlated with grip power, gait speed, skeletal mass index, numeric rating scale score, and PDAS score. In multiple linear regression analysis, SALC-F and SALC-CalF scores significantly correlated with PDAS score, skeletal mass index, and gait speed. The area under the curve were 0.70 for SARC-F and 0.88 for SARC-CalF; SARC-CalF had a significantly higher area under the curve than SARC-F. DISCUSSION: Sarcopenia was diagnosed in patients aged <65 years with chronic musculoskeletal pain. SALC-F and SARC-CalF scores showed a significant correlation with disability due to pain and were reliable sarcopenia screening tools for chronic musculoskeletal pain. SARC-CalF was more reliable than SARC-F.

ABSTRACT

Objectives

To report 24-week safety and effectiveness of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis from a post-marketing surveillance study.

Methods

Enrolled patients were newly receiving CZP. All adverse events (AEs) and adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes included: 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR) and European Alliance of Associations for Rheumatology (EULAR) response. Missing data were imputed using the last observation carried forward.

Results

3727 patients were enrolled; safety and effectiveness were evaluated in 3586 and 1794 patients, respectively. 24.9% of patients reported AEs (893/3586), 14.7% reported ADRs (528/3586), 8.3% (298/3586) reported serious AEs and 5.3% (190/3586) reported serious ADRs. Selected serious ADRs of interest: infections (110; 3.1%), tuberculosis (6; 0.2%), interstitial pneumonia (15; 0.4%), malignancy (8; 0.2%), and hepatic function disorder (7; 0.2%). No allergic reactions, autoimmune disease, cardiac failure, demyelinating diseases, or pancytopenia were reported. Mean DAS28-ESR reduced from 4.8 (baseline) to 3.4 (final evaluation). At final evaluation, 34.7% of patients achieved EULAR good response.

Conclusions

These real-world safety and effectiveness results were consistent with previously reported data, with no new safety signals identified. Long-term, real-world CZP safety and effectiveness data are needed.

ABSTRACT

Objectives

The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPGs) for the management of rheumatoid arthritis (RA) and prepare an algorithm for non-drug and surgical treatments. This article is a digest version of the guidelines.

Methods

The Japanese Ministry of Health, Labour and Welfare’s research group, in collaboration with the JCR, used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. The consensus was formed by CPG panel members.

Results

We raised 19 clinical questions regarding non-drug and surgical treatments for RA and developed recommendations. The treatments included exercise therapy; occupational therapy; joint injection of corticosteroids; and orthopaedic surgeries including cervical spine surgery, wrist and foot arthroplasty, ankle arthrodesis, and replacement arthroplasty of the shoulder, elbow, finger, hip, knee, and ankle. Recommendations regarding the risks of surgery and perioperative discontinuation of medications have also been developed. Based on these recommendations, we created an original algorithm for the non-drug and surgical treatment of RA.

Conclusions

These recommendations are expected to serve rheumatologists, health care professionals, and patients with RA as tools for shared decision-making to treat residual limb joint symptoms and functional impairment.

Abstract

Objectives

To examine the risk factors of surgical site infection (SSI), delayed wound healing, and death after orthopedic surgery in patients with rheumatoid arthritis (RA).

Methods

We identified articles indexed in the Cochrane Library, PubMed, and Japan Centra Revuo Medicina Web published from 2013 to 2019 and other articles. Articles fulfilling the predefined inclusion criteria were reviewed systematically and their quality was appraised according to the Grading of Recommendations Assessment, Development, and Evaluation system with some modifications.

Results

After inclusion and exclusion by full-text review, 29 articles were analyzed. Use of biological disease modifying antirheumatic drugs was a risk factor of SSI (risk ratio 1.66, 95% confidence interval 1.25–2.19), but not of delayed wound healing. RA itself was a risk factor of SSI, and oral glucocorticoid use was a risk factor of SSI in three of the four studies analyzed and of postoperative death. Age, male sex, comorbidities such as diabetes mellitus and chronic obstructive pulmonary disease, surgical factors such as foot/ankle and spine surgery and longer operative time were risk factors of those postoperative complications.

Conclusion

Patients with those factors should be dealt with appropriate cautions to strike a risk–benefit balance of orthopedic surgeries.

Abstract

Objectives

This study aimed to evaluate patients’ opinions regarding their rheumatoid arthritis (RA) therapy and to reflect the patients’ perspectives in the 2020 update of the Japan College of Rheumatology clinical practice guidelines.

Methods

A self-administered questionnaire was mailed to 1600 members of the Japan Rheumatology Friendship Association, who were randomly selected by age and prefecture.

Results

A total of 1156 patients returned the questionnaire (response rate, 72.3%; mean age, 63.0 ± 11.9 years). Those who reported having discussed their treatment goals with their doctors (450 respondents, 38.9%) were more likely to be satisfied with their current medical care (odds ratio, 7.13; 95% CI 4.72–10.8) compared with those who had not discussed their goals nor had them explained (287 respondents, 24.8%). The benefits exceeded the adverse effects for all pharmacotherapy (methotrexate, corticosteroids, conventional synthetic antirheumatic drugs, biological agents, Janus kinase inhibitor, and anti-RANKL antibodies). However, while 74.2% of the respondents using biological agents perceived that ‘the favorable aspects outweighed the unfavorable aspects,’ most of those taking anti-RANKL antibodies (69.2%) felt uncertain.

Conclusions

The questionnaire successfully collected information regarding patients’ perceptions regarding their therapy. Further implementation of treat-to-target is necessary in Japan to improve patient satisfaction.

Abstract

Objectives

To provide an evidence base for clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA) in older adults.

Methods

PubMed, Cochrane library, and Japan Centra Revuo Medicina databases were searched for articles published between 1990 and 2019. Quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation system, with some modifications.

Results

Among 702 identified articles, there were 5 post-hoc analyses of randomized controlled trials and 10 observational studies. Meta-analysis of the former yielded a mean difference of the van der Heijde-modified total Sharp score of −2.79 (95% confidence interval [CI] − 3.74 to −1.84) for treatment with tumor necrosis factor inhibitors. The risk ratio (RR) for the American College of Rheumatology 50% response rate, and for serious adverse events was 2.83 (95%CI 1.90–4.21) and 1.32 (95%CI 0.53–3.31), respectively, for Janus kinase inhibitors. Meta-analysis of the observational studies yielded an RR for disease activity score-28 remission and serious infections of 0.76 (95%CI 0.64–0.91) and 1.92 (95%CI 1.31–2.81) for older-versus-younger patients receiving biological disease-modifying antirheumatic drugs, respectively.

Conclusion

This systematic review provides the necessary evidence for developing CPG for the management of RA in older adults.

OBJECTIVE: It has been reported that levels of soluble CD30 in serum and joint fluid are significantly elevated in patients with rheumatoid arthritis (RA). This study aimed to investigate whether CD30 could be a therapeutic target for RA. METHODS: The expression and localization of CD30 were examined by immunohistochemical and double immunofluorescence staining on synovial tissue samples obtained from patients with RA or osteoarthritis (OA) during surgery. Changes in CD30 expression of fibroblast-like synoviocytes (FLS) from RA patients with or without TNFα and IL-1β stimulation were examined by the polymerase chain reaction (PCR) and flow cytometry. Collagen antibody-induced arthritis (CAIA) was created in DBA/1 mice, and the therapeutic effect of brentuximab vedotin (BV) was examined by clinical score, histological findings and measurement of serum levels of SAA, IL-6, and TNFα. RESULTS: CD30 expression was significantly higher in samples from patients with RA than from those with OA. Double immunofluorescence showed a low rate of co-localization of CD30 with CD20 or CD90, but a high rate of co-localization of CD30 and CD138. CD30 mRNA expression was upregulated 11.7-fold in FLS following stimulation by inflammatory cytokines. The clinical scores of CAIA mice were significantly lower following both BV treatments, however, the histological scores of CAIA mice were significantly lower only following treatment with high dose BV (70 mg/kg). CONCLUSIONS: CD30 was expressed on immunocompetent cells in synovial tissue from RA patients and in cytokine-stimulated FLS in vitro. High dose BV (70 mg/kg) showed significant therapeutic effects in ameliorating inflammation and joint destruction in CAIA mice, but low dose BV (30 mg/kg) was insufficient.

Abstract

Objective

This study aimed to evaluate satisfaction with total joint replacement (TJR) surgery among patients with rheumatoid arthritis (RA).

Methods

We mailed questionnaires to randomly selected members of the Japan Rheumatism Friendship Association, stratified by age and prefecture, throughout Japan. The questionnaire collected demographic and clinical characteristics as well as patients’ satisfaction with TJR and their current therapy.

Results

Of the 1156 patients who returned the questionnaire, 339 (29.3%) responded that they had had TJR of any type. The mean age was 66.6 years, and 94.4% were women. The mean time period from the hip and knee TJR was 14–15 years. Over half of the patients who had had TJR were satisfied with the results, especially those who had had hip (89.6%) and knee TJR (87.3%), who reported a high level of satisfaction. Multivariable linear regression analysis revealed that, in patients with knee TJR, satisfaction with current therapy was significantly related to whether they were satisfied with the results of the surgery.

Conclusion

Most patients with RA who had undergone TJR were satisfied with the results even after a long period of time, and their level of satisfaction was associated with their satisfaction with current therapy.

Abstract

Objectives

To evaluate the efficacy and safety of biosimilars compared with reference biological disease modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) as a part of the process of developing the 2020 update of the Japan College of Rheumatology guidelines for the management of RA.

Methods

PubMed, Cochrane Library, and Japan Centra Revuo Medicina were searched for articles to conduct a systematic review (SR). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system.

Results

Twenty randomized controlled trials were included (biosimilars of infliximab, etanercept, and adalimumab). A meta-analysis revealed that the risk ratios (RRs) and 95% confidence intervals (CIs) of achieving the American College of Rheumatology 50% response (ACR50) at week 24 and serious adverse events (SAEs) for biosimilars compared with the reference bDMARDs were 1.04 (0.98–1.10) and 0.84 (0.61–1.18), respectively. The RRs of achieving ACR50 and SAEs at week 24 were respectively 0.93 (0.69–1.26) and 2.15 (0.55–8.35) in the patients who switched to biosimilars from the reference bDMARDs and 0.92 (0.76–1.12) and 1.41 (0.32–6.15) in those who continued the reference bDMARDs.

Conclusion

Biosimilars and reference bDMARDs were equally useful for the management of RA.

Abstract

Objectives

This study aimed to evaluate the impact of exercise therapy on patient-reported outcomes (PROs) in rheumatoid arthritis (RA) as part of the process of updating the 2020 Japanese guidelines for the management of RA according to the Grading of Recommendations, Assessment, Development, and Evaluation system.

Methods

We searched PubMed, Japana Centra Revuo Medicina Web, and the Cochrane Library (from 2009 to 2018) to identify articles that evaluated PROs of exercise therapy and RA disease activity.

Results

A total of 662 articles were identified, including nine RCTs, and meta-analyses were performed on six RCTs on systemic exercise therapy and three RCTs on upper extremity exercise therapy. Analyzed exercise therapies were diverse, differing in target population, intervention method, and duration. Significant improvements were observed in the Health Assessment Questionnaire Disability Index (mean difference −0.35, 95% confidence interval (CI): −0.60 to −0.10), pain (standardized mean difference −2.04, 95% CI: −3.77 to −0.32), and SF-36. For upper extremity exercise therapy, significant improvements in PROs (Disabilities of the Arm, Shoulder, and Hand Questionnaire, Michigan Hand Outcome Questionnaire) were observed.

Conclusion

Exercise therapy in RA treatment improves patient subjective assessment of pain, physical function, and quality of life.

We investigated the clinical outcomes of surgical procedures for the treatment of forefoot deformities in patients with rheumatoid arthritis. Twenty feet in 16 women (mean age 62.1 years) underwent corrective osteotomy of the first metatarsal bone with shortening oblique osteotomy of the lesser metatarsophalangeal joints (joint-preservation group), while 13 feet in 12 women (mean age 67.4 years) underwent arthrodesis of the first metatarsophalangeal joint with resection arthroplasty of the lesser metatarsophalangeal joints (joint-sacrifice group); mean follow-up for each group was 25.8 and 23.8 months, respectively. The mean total Japanese Society for Surgery of the Foot (JSSF) scale improved significantly from 64.2 to 89.2 in the joint-preservation group (p < .001), and from 54.2 to 74.2 in the joint-sacrifice group (p = .003). In the joint-preservation group, the postoperative range of motion (ROM) of the joint, walking ability, and activities of daily living scores of the JSSF scale were significantly higher than those in the joint-sacrifice group (p = .001, p = .001, and p = .019, respectively). There were no differences in the subscale scores of the self-administered foot evaluation questionnaire between 2 groups either pre- or postoperatively. No differences in the postoperative complications were found between 2 groups. Although the joint-sacrificing procedure resulted in lower objective outcomes than the joint-preserving procedure regarding the ROM of the joint, the walking ability, and the level of activities of daily living, both procedures resulted in similar treatment outcomes when evaluated by the subjective measures.

Purpose

We investigated objective and patient-reported outcomes after resection arthroplasty or shortening oblique osteotomy (SOO) of the lesser metatarsals combined with arthrodesis of the first metatarsophalangeal (MTP) joint for severe rheumatoid forefoot deformities.

Methods

17 feet from 14 women (mean age, 67.8 years) underwent resection arthroplasty of the lesser metatarsal heads (MTH resection group), while 13 feet from nine women and two men (mean age, 68.7 years) underwent SOO of the lesser metatarsals (MTH preservation group). Arthrodesis of the first MTP joint was performed in all cases. Mean follow-up in the MTH resection and preservation groups was 25.0 and 21.3 months, respectively. Preoperative and postoperative clinical evaluation included Japanese Society for Surgery of the Foot (JSSF) scale and self-administered foot evaluation questionnaire (SAFE-Q) scores.

Results

Mean total JSSF scale significantly improved from 53.4 to 76.4 in the MTH resection group ( p &lt; .001) and from 50.1 to 74.2 in the MTH preservation group ( p = .002). Pain and pain-related and shoe-related SAFE-Q subscale scores significantly improved after surgery in both groups. In the MTH resection group, recurrence of painful callosities and claw toe deformity was observed in four and three feet, respectively. In the MTH preservation group, one patient experienced recurrence of painful callosities and one underwent revision surgery for IP joint dislocation.

Conclusion

Resection arthroplasty or SOO of the lesser metatarsals combined with arthrodesis of the first MTP joint achieved significant improvement with respect to pain relief, deformity correction, and footwear comfort.

<title>Abstract</title>Osteoarthritis (OA), the most common aging-related joint disease, is caused by an imbalance between extracellular matrix synthesis and degradation. Here, we discover that both strands of microRNA-455 (miR-455), -5p and -3p, are up-regulated by Sox9, an essential transcription factor for cartilage differentiation and function. Both miR-455-5p and -3p are highly expressed in human chondrocytes from normal articular cartilage and in mouse primary chondrocytes. We generate miR-455 knockout mice, and find that cartilage degeneration mimicking OA and elevated expression of cartilage degeneration-related genes are observed at 6-months-old. Using a cell-based miRNA target screening system, we identify hypoxia-inducible factor-2α (HIF-2α), a catabolic factor for cartilage homeostasis, as a direct target of both miR-455-5p and -3p. In addition, overexpression of both miR-455-5p and -3p protect cartilage degeneration in a mouse OA model, demonstrating their potential therapeutic value. Furthermore, knockdown of HIF-2α in 6-month-old miR-455 knockout cartilage rescues the elevated expression of cartilage degeneration-related genes. These data demonstrate that both strands of a miRNA target the same gene to regulate articular cartilage homeostasis.

人工関節感染の有意なリスク因子として、BMI、DM、ステロイド、低アルブミン、関節リウマチ(RA)、輸血、悪性腫瘍、免疫低下、手術時間の延長、過去の手術歴などが指摘されており、疾患活動性のコントロールを含めて術前に可能な限り改善しせめて手術に臨むべきである。抗リウマチ薬には免疫抑制効果の懸念があり、長期の休薬はRAの再燃を惹起する可能性があるため、周術期の薬剤マネジメントが重要である。メトトレキサート(MTX)については、わが国のガイドラインでは12.5mg/週以下の使用量であれば再燃のリスクを抑制し、術後感染症、創傷治癒遅延に影響しないとされているため、休薬の必要はない。生物学的製剤、JAK阻害薬は免疫抑制作用によってSSIのリスクを増大させる可能性があるが、現時点では休薬期間を設けることによって安全に整形外科手術が可能である。(著者抄録)

We investigated the effects of adipose-derived extract (AE) on cultured chondrocytes and in vivo cartilage destruction. AE was prepared from human adipose tissues using a nonenzymatic approach. Cultured human chondrocytes were stimulated with interleukin-1 beta (IL-1β) with or without different concentrations of AE. The effects of co-treatment with AE on intracellular signaling pathways and their downstream gene and protein expressions were examined using real-time PCR, Western blotting, and immunofluorescence staining. Rat AE prepared from inguinal adipose tissues was intra-articularly delivered to the knee joints of rats with experimental osteoarthritis (OA), and the effect of AE on cartilage destruction was evaluated histologically. In vitro, co-treatment with IL-1β combined with AE reduced activation of the p38 and ERK mitogen-activated protein kinase (MAPK) pathway and nuclear translocation of the p65 subunit of nuclear factor-kappa B (NF-κB), and subsequently downregulated the expressions of matrix metalloproteinase (MMP)-1, MMP-3, MMP-13, a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS)-4, IL-6, and IL-8, whereas it markedly upregulated the expression of IL-1 receptor type 2 (IL-1R2) in chondrocytes. Intra-articular injection of homologous AE significantly ameliorated cartilage destruction six weeks postoperatively in the rat OA model. These results suggested that AE may exert a chondroprotective effect, at least in part, through modulation of the IL-1β-induced inflammatory signaling pathway by upregulation of IL-1R2 expression.

OBJECTIVES: To examine the risk factors of surgical site infection (SSI), delayed wound healing, and death after orthopedic surgery in patients with rheumatoid arthritis (RA). METHODS: We identified articles indexed in the Cochrane Library, PubMed, and Japan Centra Revuo Medicina Web published from 2013 to 2019 and other articles. Articles fulfilling the predefined inclusion criteria were reviewed systematically and their quality was appraised according to the Grading of Recommendations Assessment, Development, and Evaluation system with some modifications. RESULTS: After inclusion and exclusion by full-text review, 29 articles were analyzed. Use of biological disease modifying antirheumatic drugs was a risk factor of SSI (risk ratio 1.66, 95% confidence interval 1.25-2.19), but not of delayed wound healing. RA itself was a risk factor of SSI, and oral glucocorticoid use was a risk factor of SSI in three of the four studies analyzed and of postoperative death. Age, male sex, comorbidities such as diabetes mellitus and chronic obstructive pulmonary disease, surgical factors such as foot/ankle and spine surgery and longer operative time were risk factors of those postoperative complications. CONCLUSION: Patients with those factors should be dealt with appropriate cautions to strike a risk-benefit balance of orthopedic surgeries.

Dorsal dislocation of metatarsophalangeal (MTP) joints of the lesser toe frequently occurs in patients with rheumatoid arthritis (RA), and may cause painful and uncomfortable plantar callosities and ulceration. The current study examined the reliability and clinical relevance of a novel radiographic parameter (the MTP overlap distance [MOD]) in evaluating the severity of MTP joint dislocation. The subjects of the current study were 147 RA patients (276 feet; 1104 toes). MOD, defined as the overlap distance of the metatarsal head and the proximal end of the phalanx, was measured on plain radiographs. The relationship between the MOD and clinical complaints (forefoot pain and/or callosity formation) was analyzed to create a severity grading system. As a result, toes with callosities had a significantly larger MOD. ROC analysis revealed that the MOD had a high AUC for predicting an asymptomatic foot (-0.70) and callosities (0.89). MOD grades were defined as follows: grade 1, 0 ≤ MOD < 5 mm; grade 2, 5 ≤ MOD < 10 mm; and grade 3, MOD ≥ 10 mm. The intra- and inter-observer reliability of the MOD grade had high reproducibility. Furthermore, the MOD and MOD grade improved significantly after joint-preserving surgeries for lesser toe deformities. Our results suggest that MOD and MOD grade might be useful tools for the evaluation of deformities of the lesser toe and the effect of surgical intervention for MTP joints in patients with RA.

OBJECTIVES: This study aimed to evaluate patients' opinions regarding their rheumatoid arthritis (RA) therapy and to reflect the patients' perspectives in the 2020 update of the Japan College of Rheumatology clinical practice guidelines. METHODS: A self-administered questionnaire was mailed to 1600 members of the Japan Rheumatology Friendship Association, who were randomly selected by age and prefecture. RESULTS: A total of 1156 patients returned the questionnaire (response rate, 72.3%; mean age, 63.0 ± 11.9 years). Those who reported having discussed their treatment goals with their doctors (450 respondents, 38.9%) were more likely to be satisfied with their current medical care (odds ratio, 7.13; 95% CI 4.72-10.8) compared with those who had not discussed their goals nor had them explained (287 respondents, 24.8%). The benefits exceeded the adverse effects for all pharmacotherapy (methotrexate, corticosteroids, conventional synthetic antirheumatic drugs, biological agents, Janus kinase inhibitor, and anti-RANKL antibodies). However, while 74.2% of the respondents using biological agents perceived that 'the favorable aspects outweighed the unfavorable aspects,' most of those taking anti-RANKL antibodies (69.2%) felt uncertain. CONCLUSIONS: The questionnaire successfully collected information regarding patients' perceptions regarding their therapy. Further implementation of treat-to-target is necessary in Japan to improve patient satisfaction.

OBJECTIVES: To provide an evidence base for clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA) in older adults. METHODS: PubMed, Cochrane library, and Japan Centra Revuo Medicina databases were searched for articles published between 1990 and 2019. Quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation system, with some modifications. RESULTS: Among 702 identified articles, there were 5 post-hoc analyses of randomized controlled trials and 10 observational studies. Meta-analysis of the former yielded a mean difference of the van der Heijde-modified total Sharp score of -2.79 (95% confidence interval [CI] - 3.74 to -1.84) for treatment with tumor necrosis factor inhibitors. The risk ratio (RR) for the American College of Rheumatology 50% response rate, and for serious adverse events was 2.83 (95%CI 1.90-4.21) and 1.32 (95%CI 0.53-3.31), respectively, for Janus kinase inhibitors. Meta-analysis of the observational studies yielded an RR for disease activity score-28 remission and serious infections of 0.76 (95%CI 0.64-0.91) and 1.92 (95%CI 1.31-2.81) for older-versus-younger patients receiving biological disease-modifying antirheumatic drugs, respectively. CONCLUSION: This systematic review provides the necessary evidence for developing CPG for the management of RA in older adults.

OBJECTIVES: This retrospective study aimed to investigate the risk factors associated with delayed wound healing (DWH) after orthopedic surgery in rheumatoid arthritis (RA) patients treated with biological disease-modifying antirheumatic drugs (bDMARDs). METHODS: We reviewed medical records of 276 orthopedic procedures for 187 RA patients treated with bDMARDs. As a preoperative nutritional status assessment, we evaluated body mass index, prognostic nutritional index (PNI), and controlling nutritional status (CONUT). We evaluated DAS28-CRP, DAS28-ESR, face scale, global health, and HAQ-DI to assess the disease activity. Univariate and multivariate logistic regression analyses were performed to evaluate the risk factors for DWH. RESULTS: In 276 procedures, DWH was identified in 24 patients (8.7%). Disease duration, foot and ankle surgery, and preoperative use of tocilizumab were significant in the univariate analyses. These variables were entered into a multivariate model, and it was revealed that preoperative use of tocilizumab and procedures in the foot and ankle were associated with an increased risk of DWH. CONCLUSION: The current retrospective study suggested that preoperative use of tocilizumab and procedures in the foot and ankle were risk factors for DWH.

OBJECTIVE: This study aimed to evaluate satisfaction with total joint replacement (TJR) surgery among patients with rheumatoid arthritis (RA). METHODS: We mailed questionnaires to randomly selected members of the Japan Rheumatism Friendship Association, stratified by age and prefecture, throughout Japan. The questionnaire collected demographic and clinical characteristics as well as patients' satisfaction with TJR and their current therapy. RESULTS: Of the 1156 patients who returned the questionnaire, 339 (29.3%) responded that they had had TJR of any type. The mean age was 66.6 years, and 94.4% were women. The mean time period from the hip and knee TJR was 14-15 years. Over half of the patients who had had TJR were satisfied with the results, especially those who had had hip (89.6%) and knee TJR (87.3%), who reported a high level of satisfaction. Multivariable linear regression analysis revealed that, in patients with knee TJR, satisfaction with current therapy was significantly related to whether they were satisfied with the results of the surgery. CONCLUSION: Most patients with RA who had undergone TJR were satisfied with the results even after a long period of time, and their level of satisfaction was associated with their satisfaction with current therapy.

BACKGROUND: Many histological, mechanical, and clinical studies have been performed on the medial meniscus posterior root attachment, as it often tears in patients with osteoarthritic knee. Medial meniscal root repair is recommended in clinical situations; however, to date, no studies have examined the differences between meniscal root and horn cells. The aim of this study was, therefore, to investigate the morphology, reaction to cyclic tensile strain, and gene expression levels of medial meniscal root and horn cells. METHODS: Meniscal samples were obtained from the medial knee compartments of 10 patients with osteoarthritis who underwent total knee arthroplasty. Root and horn cells were cultured in Dulbecco's modified Eagle's medium without enzymes. The morphology, distribution, and proliferation of medial meniscal root and horn cells, as well as the gene and protein expression levels of Sry-type HMG box 9 and type II collagen, were determined after cyclic tensile strain treatment. RESULTS: Horn cells had a triangular morphology, whereas root cells were fibroblast-like. The number of horn cells positive for Sry-type HMG box 9 and type II collagen was considerably higher than that of root cells. Although root and horn cells showed similar levels of proliferation after 48, 72, or 96 h of culture, more horn cells than root cells were lost following a 2-h treatment with 5% and 10% cyclic tensile. Sry-type HMG box 9 and α1(II) collagen mRNA expression levels were significantly enhanced in both cells after 2- and 4-h cyclic tensile strain (5%) treatment. CONCLUSIONS: Medial meniscal root and horn cells have distinct morphologies, reactions to mechanical stress, and cellular phenotypes. Our results suggest that physiological tensile strain is important to activate extracellular matrix production in horn cells.

OBJECTIVES: This study aimed to evaluate the impact of exercise therapy on patient-reported outcomes (PROs) in rheumatoid arthritis (RA) as part of the process of updating the 2020 Japanese guidelines for the management of RA according to the Grading of Recommendations, Assessment, Development, and Evaluation system. METHODS: We searched PubMed, Japana Centra Revuo Medicina Web, and the Cochrane Library (from 2009 to 2018) to identify articles that evaluated PROs of exercise therapy and RA disease activity. RESULTS: A total of 662 articles were identified, including nine RCTs, and meta-analyses were performed on six RCTs on systemic exercise therapy and three RCTs on upper extremity exercise therapy. Analyzed exercise therapies were diverse, differing in target population, intervention method, and duration. Significant improvements were observed in the Health Assessment Questionnaire Disability Index (mean difference -0.35, 95% confidence interval (CI): -0.60 to -0.10), pain (standardized mean difference -2.04, 95% CI: -3.77 to -0.32), and SF-36. For upper extremity exercise therapy, significant improvements in PROs (Disabilities of the Arm, Shoulder, and Hand Questionnaire, Michigan Hand Outcome Questionnaire) were observed. CONCLUSION: Exercise therapy in RA treatment improves patient subjective assessment of pain, physical function, and quality of life.

Objectives: To evaluate the efficacy and safety of tacrolimus in adult patients with rheumatoid arthritis (RA) by using the GRADE approach. Methods: We searched PubMed, Japana Centra Revuo Medicina Web (Ichu-shi web), and the Cochrane Database of Systematic Reviews. Articles fulfilling the predefined inclusion criteria were appraised and used for meta-analysis. The primary outcomes were American College of Rheumatology 20 (ACR20) and serum creatinine elevation. Other outcomes included ACR50, ACR70, changes in C-reactive protein, modified Health Assessment Questionnaire Disability Index, gastrointestinal disorders, metabolic and nutritional disorders, and infections and infestations. Results: We identified five randomized controlled studies, four of which compared tacrolimus to placebo and were included in the meta-analysis. The risk ratio of ACR20 achievement was 1.71 (95% confidence interval [CI] 1.20-2.42) for 1-2 mg/day and 2.30 (95% CI 1.79-2.96) for 3 mg/day. The risk ratio of creatinine elevation was 1.95 (95% CI 1.18-3.23) for 1-2 mg/day and 3.81 (95% CI 2.43-5.99) for 3 mg/day. Conclusion: Tacrolimus is effective with acceptable safety in the management of RA.

We investigated the expression and localization of the receptor activator nuclear factor κB ligand (RANKL) in cartilage from patients with rheumatoid arthritis (RA) of relevance to cartilage degeneration. We also examined the role of exogenous lymphotoxin (LT)-α on RANKL expression in human chondrocytes and its effect on in vitro osteoclast differentiation. Cartilage and synovial fluid samples were obtained from 45 patients undergoing total joint replacement surgery or joint puncture, including 24 patients with osteoarthritis (OA) and 21 patients with RA. RANKL expression in articular cartilage was examined by immunohistochemistry. LT-α concentrations in synovial fluid were measured using an enzyme-linked immunosorbent assay (ELISA). Normal human chondrocytes were stimulated with LT-α, and the relative mRNA levels of RANKL, osteoprotegerin (OPG), matrix metalloproteinase-9, and vascular endothelial growth factor were examined by real-time polymerase chain reaction. Soluble RANKL protein in culture media was measured using ELISA, and membrane-bound RANKL protein in cells was examined by western blotting. Co-cultures of human chondrocytes with peripheral blood mononuclear cells (PBMCs) were stimulated with macrophage-colony stimulating factor and LT-α, and osteoclast differentiation was evaluated by staining for tartrate-resistant acid phosphatase. LT-α concentrations were higher in RA synovial fluid than in OA samples. The population of RANKL-positive chondrocytes of RA cartilage was higher than that of OA cartilage, and correlated with cartilage degeneration. Stimulation of cultured human chondrocytes by LT-α increased RANKL expression, the RANKL/OPG ratio, and angiogenic factors. Membrane-bound RANKL in chondrocytes was up-regulated after stimulation of LT-α, whereas soluble RANKL in culture medium did not increase. Co-cultures of human chondrocytes and PBMCs demonstrated that LT-α stimulated human chondrocytes to produce RANKL and induced osteoclastic differentiation of PBMCs. RANKL produced by chondrocytes may contribute to cartilage destruction during RA and LT-α could promote the expression of RANKL in human chondrocytes.

BACKGROUND: Prevention and treatment for locomotive syndrome (LS) are important for extending healthy life expectancy. The 25-question geriatric locomotive function scale (GLFS-25) was developed to diagnose LS. The Fear-Avoidance model was proposed to explain pain chronicity. LS and chronic pain decrease activities of daily living; however, the relationships between LS and factors related to chronic pain in the Fear-Avoidance model are unknown. Objective of the current study was to assess the prevalence of LS and examine the factors of the Fear-Avoidance model and the GLFS-25 that affect the prevalence of LS in patients with chronic pain. METHODS: Participants included 281 patients (99 men, 182 women) aged over 40 years with chronic pain who visited our outpatient clinic for chronic pain. All participants completed the GLFS-25, numeric rating scale (NRS), pain catastrophizing scale (PCS), hospital anxiety and depression scale (HADS), and Athene insomnia scale (AIS). According to a GLFS-25 cutoff point, participants were divided into three groups (LS-2; GLFS-25 ≥ 16, LS-1; 7 ≤ GLFS-25 < 16, and non-LS; GLFS-25 < 7 points) and each parameter was compared among the groups, followed by multiple logistic regression analysis. Next, multiple linear regression analysis was performed to determine the factors associated with the GLFS-25. RESULTS: Of all 281 patients, 241 (85.8%) patients were diagnosed with LS-2. Univariate analysis revealed there were significant differences in NRS, PCS, HADS anxiety, HADS depression, and AIS among groups. Multiple logistic regression analyses showed PCS was significantly associated with LS-2 prevalence. The GLFS-25 was positively correlated with NRS, HADS depression, AIS in multiple linear regression analysis. CONCLUSIONS: We found that patients with chronic pain in our outpatient clinic had a significant rate of LS-2. The prevalence of LS-2 was significantly correlate with pain catastrophizing, and the GLFS-25 was significantly correlated with higher pain intensity, depression, and insomnia.

BACKGROUND: Mirogabalin, which is approved for the treatment of peripheral neuropathic pain in Japan, is a ligand for the α2δ subunit of voltage-gated calcium channels. Both pregabalin and mirogabalin act as nonselective ligands at the α2δ-1 and α2δ-2 subunits. Mirogabalin has a unique binding profile and long duration of action. Pregabalin has been reported to produce intolerable adverse effects in some patients. This study investigated outcomes associated with mirogabalin administration in patients with peripheral neuropathic pain who ceased treatment with pregabalin. METHODS: We retrospectively assessed peripheral neuropathic pain using the neuropathic pain screening questionnaire (NeP score) in 187 patients (58 men, 129 women) who were treated with mirogabalin. All patients had switched from pregabalin to mirogabalin due to lack of efficacy or adverse events. Differences in the treatment course (i.e., numeric rating scale (NRS) scores) were compared using one-way analysis of variance with Bonferroni post hoc tests. RESULTS: The mean age of the patients was 72.3 years (range, 30-94 years), and the mean duration of disease was 37 months (range, 3-252 months). After treatment with mirogabalin for 1 week, NRS scores significantly decreased compared with baseline and continued to decrease over time. After 8 weeks, NRS scores improved by ≥ 30% from baseline in 113 patients (69.3%). Twenty-four patients (12.8%) stopped mirogabalin treatment due to adverse events. Somnolence (26.7%), dizziness (12.3%), edema (5.9%), and weight gain (0.5%) were noted as adverse events of mirogabalin. CONCLUSIONS: The results of this investigation indicate that mirogabalin is safe and effective for reducing peripheral neuropathic pain.

In patients with osteoarthritis (OA), there is a decrease in both the concentration and molecular size of hyaluronan (HA) in the synovial fluid and cartilage. Cell migration-inducing hyaluronidase 1 (CEMIP), also known as hyaluronan (HA)-binding protein involved in HA depolymerization (HYBID), was recently reported as an HA depolymerization-related molecule expressed in the cartilage of patients with OA. However, the underlying mechanism of CEMIP regulation is not well understood. We found that CEMIP expression was transiently increased by interleukine-1β (IL-1β) stimulation in chondrocytic cells. We also observed that ERK activation and NF-κB nuclear translocation were involved in the induction of CEMIP by IL-1β. In addition, both administration of HA and mechanical strain attenuated the CEMIP induction in IL-1β-stimulated chondrocytes. In conclusion, we clarified the regulatory mechanism of CEMIP in chondrocytes by inflammatory cytokines and suggested the potential involvement in osteoarthritis development.

<sec><title>Objective.</title>To investigate whether abatacept (ABA) causes more adverse events (AE) than conventional synthetic disease-modifying antirheumatic drugs (csDMARD) after orthopedic surgery in patients with rheumatoid arthritis (RA).

</sec><sec><title>Methods.</title>A retrospective multicenter nested case–control study was performed in 18 institutions. Patients receiving ABA (ABA group) were matched individually with patients receiving csDMARD and/or steroids (control group). Postoperative AE included surgical site infection, delayed wound healing, deep vein thrombosis or pulmonary embolism, flare, and death. The incidence rates of the AE in both groups were compared with the Mantel-Haenszel test. Risk factors for AE were analyzed by logistic regression model.

</sec><sec><title>Results.</title>A total of 3358 cases were collected. After inclusion and exclusion, 2651 patients were selected for matching, and 194 patients in 97 pairs were chosen for subsequent comparative analyses between the ABA and control groups. No between-group differences were detected in the incidence rates of each AE or in the incidence rates of total AE (control vs ABA: 15.5% vs 20.7% in total, 5.2% vs 3.1% in death).

</sec><sec><title>Conclusion.</title>Compared with csDMARD and/or steroids without ABA, adding ABA to the treatment does not appear to increase the incidence rates of postoperative AE in patients with RA undergoing orthopedic surgery. Large cohort studies should be performed to add evidence for the perioperative safety profile of ABA.

Idiopathic chondrolysis of the hip (ICH), a very rare disorder of unknown etiology, occurs mainly in female adolescents. Characterized by pain, limp, stiffness and radiological narrowing joint space from the rapid destruction of the articular cartilage, ICH sometimes results in ankyloses. We present the case of a 10-year-old girl diagnosed with ICH based on arthroscopic inspection and synovium biopsy. The femoral deformity appeared gradually, like a cam-type femoroacetabular impingement. She was treated with intensive rehabilitation and immunosuppressive drug. We later performed an arthroscopic bumpectomy for residual symptoms. She achieved a favorable outcome as a 15-year-old at the latest follow-up.

BACKGROUND: To reveal trends in bone microarchitectural parameters with increasing spatial resolution on ultra-high-resolution computed tomography (UHRCT) in vivo and to compare its performance with that of conventional-resolution CT (CRCT) and micro-CT ex vivo. METHODS: We retrospectively assessed 5 tiger vertebrae ex vivo and 16 human tibiae in vivo. Seven-pattern and four-pattern resolution imaging were performed on tiger vertebra using CRCT, UHRCT, and micro-CT, and on human tibiae using UHRCT. We measured six microarchitectural parameters: volumetric bone mineral density (vBMD), trabecular bone volume fraction (bone volume/total volume, BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular separation (Tb.Sp), and connectivity density (ConnD). Comparisons between different imaging resolutions were performed using Tukey or Dunnett T3 test. RESULTS: The vBMD, BV/TV, Tb.N, and ConnD parameters showed an increasing trend, while Tb.Sp showed a decreasing trend both ex vivo and in vivo. Ex vivo, UHRCT at the two highest resolutions (1024- and 2048-matrix imaging with 0.25-mm slice thickness) and CRCT showed significant differences (p ≤ 0.047) in vBMD (51.4 mg/cm3 and 63.5 mg/cm3 versus 20.8 mg/cm3), BV/TV (26.5% and 29.5% versus 13.8 %), Tb.N (1.3 l/mm and 1.48 l/mm versus 0.47 l/mm), and ConnD (0.52 l/mm3 and 0.74 l/mm3 versus 0.02 l/mm3, respectively). In vivo, the 512- and 1024-matrix imaging with 0.25-mm slice thickness showed significant differences in Tb.N (0.38 l/mm versus 0.67 l/mm, respectively) and ConnD (0.06 l/mm3 versus 0.22 l/mm3, respectively). CONCLUSIONS: We observed characteristic trends in microarchitectural parameters and demonstrated the potential utility of applying UHRCT for microarchitectural analysis.

BACKGROUND: The fear-avoidance model is a theoretical paradigm for explaining acute and chronic pain. In this model, pain catastrophizing plays an important role. On the other hand, self-efficacy influences whether patients view their pain optimistically, ultimately preventing the conversion of pain into intractable pain. The aim of the present study was to evaluate the factors that influence self-efficacy in patients with chronic pain. METHODS: Study participants included 147 outpatients (35 men, 112 women) with intractable chronic pain who visited our hospital between September 2014 and July 2015. Their mean age was 71.0 (range 32-92) years. Pain sites were as follows: low back, 97 patients; knee, 71 patients; shoulder, 34 patients; and hip, 15 patients. All patients were assessed using the following measures: Numeric Rating Scale (NRS), Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS), Pain Disability Assessment Scale (PDAS), and Pain Self-Efficacy Questionnaire (PSEQ). All participants were further divided into two groups based on median PSEQ scores (group L: PSEQ of 35 points or less, n = 74; group H: PSEQ greater than 35 points, n = 73). The factors that influenced self-efficacy in these patients were analyzed using univariate and multiple linear regression analyses. RESULTS: Significant differences were observed in gender; pain duration; and NRS, PDAS, HADS, and PCS scores between group L and group H. Multiple linear regression analysis revealed that self-efficacy was correlated with PDAS score, HADS depression score, and pain duration. CONCLUSIONS: Patients with longer pain duration indicated greater self-efficacy and patients with higher pain disability and depression exhibited lower self-efficacy.

The fixation technique of bony fragments is crucial for the bone union of the tuberosities after humeral head replacement (HHR) for a comminuted fracture of the proximal humerus. To increase the bone union rate, we reduce tuberosities to overlap on the humeral shaft by approx. 1 cm and fix them with cable wire. Herein, we retrospectively investigated the clinical and radiographic outcomes of our procedure. Twenty-six patients who underwent cementless HHR for the treatment of comminuted fractures of the proximal humerus were investigated. The Constant-Murley score, active shoulder mobility, and bone union rate were evaluated. The mean duration of follow-up was 56.3 months (range 24-197). At the final follow-up, the average Constant-Murley score was 58 (range 40-76). Forward elevation was 126° on average (range 35°-180°). Twenty-three cases (88%) showed bone union between the tuberosities and the shaft at an average follow-up of 4.1 months (range 4-5 months) after surgery. Non-union was noted in 1 case, and bone resorption was noted in 2 cases. The bone union rate and the clinical outcome of our procedure were relatively favorable.

We investigated the prevalence of and risk factors for the progression of upper cervical lesions (UCLs) in patients with rheumatoid arthritis (RA). A retrospective analysis of 49 patients with RA (4 males, 45 females) was conducted. The UCLs included atlanto-axial subluxation and vertical subluxation. We investigated the clinical factors including the Disease Activity Score 28 based on C-reactive protein (DAS28-CRP) and the modified Health Assessment Questionnaire-Disability Index as well as radiographic changes between the baseline (at May 2010 to April 2013) and final follow-up. Forty patients (81.6%) were classified as the non-progressive group, and the other 9 patients (18.4%) comprised the progressive group. The progressive group's final CRP values, baseline or final MMP-3 levels, DAS28-CRP, and rate of pre-existing lesions at baseline were all significantly higher than those of the non-progressive group (p=0.017, p=0.043, p=0.002, p=0.008, p<0.001, and p=0.008 respectively). A multivariate logistic regression analysis demonstrated that DAS28-CRP at baseline was a risk factor for radiographic progression (p=0.018, odds ratio: 2.54, 95% confidence interval: 1.17-5.51). Our findings indicate that higher disease activity might influence the progression of UCLs in patients with RA.

Hyaluronan (HA) is an extracellular matrix (ECM) component of articular cartilage and has been used to treat patients with osteoarthritis (OA). A disintegrin and metalloproteinases with thrombospondin motifs (ADAMTSs) play an important role in cartilage degradation in OA. We have previously reported that ADAMTS4 and ADAMTS9 were induced by cytokine stimulation. However, the effect of HA on the cytokine-inducible ADAMTS9 has never been investigated. Moreover, it is unclear whether HA protects cartilage by suppressing aggrecan degradation. Here, we examined the effects of HA on ADAMTS expression in vitro and on cartilage degradation in vivo. ADAMTS9 expression was higher than that of the other aggrecanases (ADAMTS4 and 5) in human chondrocytes, chondrocytic cells, and rat cartilage. ADAMTS4 and 9 mRNA levels were upregulated in cytokine-stimulated chondrocytes and chondrocytic cells. Pre-incubation with HA significantly inhibited ADAMTS9 mRNA expression in cytokine-stimulated cells. In a rat OA model, Adamts5 and 9 mRNA levels were transiently increased after surgery; intra-articular HA injections attenuated the induction of Adamts5 and 9 mRNA. HA also blocked aggrecan cleavage by aggrecanase in OA rats in a molecular size-dependent manner. These results demonstrate that HA attenuates induced aggrecanases expression in OA and thereby protects articular cartilage degradation by this enzyme. Our findings provide insight into the molecular basis for the beneficial effects of HA in OA. © 2018 The Authors.

関節リウマチに対する尺骨遠位端切除術を併用した手関節部分固定術の治療成績を検討した.術後5年以上経過観察可能であった19例23手を対象とした.症例は全て女性で,手術時年齢は平均50.7歳,経過観察期間は平均9.9年であった.手術は橈骨月状骨間固定術が21手,橈骨月状骨三角骨間固定術が2手であり,術前のSchulthess分類はType IIが15手,Type IIIが8手であった.良好な除痛効果と手関節アライメントの矯正・維持が獲得されていた.最終調査時には掌背屈可動域に減少を認めたが,術後月状骨周囲に骨性硬直を生じた群で顕著であり,その頻度はSchulthess分類Type IIIの手関節で高かった.そのため手根中央関節の破壊が高度である場合は,手関節部分固定術後に月状骨周囲骨性強直が発生し,手関節アライメント異常の矯正は獲得される一方で,掌背屈可動域減少が生じる可能性が高いと考える.(著者抄録)

＜Key Points＞◎慢性疼痛の治療は、個人差の大きいことから、その背景を十分に理解した上で、個別化した治療(医療)を提供する必要がある。◎慢性疼痛治療の目標は、「ADLとQOLの改善」であり、「痛みゼロ」を最重要目標としていない点でがん性疼痛治療と大きく異なっている。◎薬物療法マネジメントにおいて、薬剤使用の見極め(減量、中止や別の薬への変更)と副作用の発現リスクへの配慮が重要である。◎副作用マネジメントにおいて、漫然とした処方継続の回避と定期的な血液検査の奨励が必須である。◎高齢で慢性疼痛を呈する患者も多く、高齢者は副作用リスクも高いことから注意が必要である。(著者抄録)
