Abstract

Objective

To evaluate the ability to discriminate giant cell arteritis (GCA) from Takayasu arteritis (TAK) according to the modified 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) GCA classification criteria.

Methods

Patients enrolled in the Japanese nationwide retrospective registry were evaluated using the criteria with partial modification; wall thickening of descending thoracic-abdominal aorta were mainly diagnosed by contrast-enhanced computed tomography (CT) or magnetic resonance imaging instead of evaluating with positron emission tomography (PET)-CT. The discriminability of the criteria was evaluated using C-statistic (> 0.7: good ability).

Results

Newly diagnosed patients with GCA (n = 139) and TAK (n = 129) were assessed, and 23.3% of TAK were aged 50 years or older at onset. The sensitivity of the modified 2022 ACR/EULAR GCA classification criteria with a score ≥ 6 was 82.0%, 68.5%, and 32.1% in all GCA, GCA with large-vessel involvement, and GCA without cranial arteritis, respectively. The specificity of the modified criteria was 96.1% for the 129 TAK as controls. Five patients with late-onset TAK met the modified criteria, and four had cranial signs and symptoms, two had bilateral axillary artery involvement, and four had descending thoracic-abdominal aorta involvement. The discriminability of the criteria was good (C-statistic: 0.986, 95% confidence interval [CI]: 0.976–0.996) and remained good after excluding age (C-statistic: 0.927, 95% CI: 0.894–0.961). The discriminability of a set of large-vessel lesions (bilateral axillary artery and descending thoracic-abdominal aorta) and inflammatory markers was markedly decreased with poor C-statistic value (C-statistic: 0.598, 95% CI: 0.530–0.667). Discriminability was improved after adding polymyalgia rheumatica (PMR) (C-statistic: 0.757, 95% CI: 0.700–0.813) or age (C-statistic: 0.913, 95%CI: 0.874–0.951) to the set of large-vessel lesions. In GCA patients with a score ≤ 5, 52% had bilateral subclavian and/or axillary artery involvement.

Conclusion

The modified 2022 ACR/EULAR GCA classification criteria well performed in classifying GCA and TAK without PET-CT in routine clinical practice. A set of items included in the modified GCA classification criteria had good discriminative ability for GCA and TAK, even when age was excluded. However, age restriction or PMR was required to distinguish GCA without cranial lesions from TAK.

CKD public education plays a very important role in effective chronic kidney disease (CKD) countermeasure. We have been conducting CKD public education programs in Okayama Prefecture since 2007. Here, we aimed to examine the actual status of CKD perceptance and changes in CKD perceptance due to these education programs. The study was conducted on individuals who underwent health checkups at 12 medical institutions across five medical regions in Okayama Prefecture between 1 October and 30 November in 2015, 2019, and 2023. The results showed that overall CKD perceptance has improved over time (perceptance of "CKD" 4% to 7%, "chronic kidney disease" 27% to 34%, 2015 vs. 2023). "Chronic kidney disease" was more commonly recognized than "CKD", and the elderly were more aware of the disease than younger people. The CKD perceptance improved across all age groups. However, the rate of CKD perceptance is still low, especially among young people. Previously, newspapers were the second most common resource of information about CKD after television. However, the Internet has recently replaced newspapers as the second most common source of information, especially among younger people. Understanding of the exact diagnosis of CKD also remains insufficient. It is necessary to continue more effective CKD public education programs through more intelligible terminology and information sources that match the demographics of target population.

記述言語：英語掲載種別：研究論文（学術雑誌）

Cronkhite-Canada syndrome (CCS) is a non-hereditary disorder characterized by non-neoplastic hamartomatous gastrointestinal polyposis, hair loss, nail atrophy, hyperpigmentation, and diarrhea. While the relationship between CCS and nephritis remains unclear, seven cases of nephritis complicated by CCS have been reported to date, all of which were membranous nephropathy (MN). A 57-year-old man presented with taste disturbance, hair loss, nail plate atrophy, skin pigmentation, and frequent diarrhea. Endoscopic findings showed multiple polyposis of the stomach and large intestine. Given the above, he was diagnosed with CCS. The symptoms gradually improved with prednisolone treatment, although urinary protein and hypoproteinemia appeared during the tapering of prednisolone. He was diagnosed with MN using a renal biopsy, and immunofluorescence microscopy with IgG subclass staining showed predominantly diffuse granular capillary wall staining of IgG4. The cause of secondary MN was not found, including malignant tumors. Nephrotic-range proteinuria persisted despite treatment with prednisolone and cyclosporine. Additional treatment with mizoribine resulted in incomplete remission type 1 of nephrotic syndrome, suggesting that mizoribine may be a treatment option for patients with CCS with steroid-resistant MN. Considering a high prevalence of hypoproteinemia due to chronic diarrhea and protein-losing enteropathy in patients with CCS, proteinuria might be overlooked; thus, follow-up urinalysis would be recommended in patients with CCS.

INTRODUCTION: ACE cleaves angiotensin I (Ang I) to angiotensin II (Ang II) inducing vasoconstriction via Ang II type 1 (AT1) receptor, while ACE2 cleaves Ang II to Ang (1-7) causing vasodilatation by acting on the Mas receptor. In diabetic kidney disease (DKD), it is still unclear whether plasma or urine ACE2 levels predict renal outcomes or not. RESEARCH DESIGN AND METHODS: Among 777 participants with diabetes enrolled in the Urinary biomarker for Continuous And Rapid progression of diabetic nEphropathy study, the 296 patients followed up for 9 years were investigated. Plasma and urinary ACE2 levels were measured by the ELISA. The primary end point was a composite of a decrease of estimated glomerular filtration rate (eGFR) by at least 30% from baseline or initiation of hemodialysis or peritoneal dialysis. The secondary end points were a 30% increase or a 30% decrease in albumin-to-creatinine ratio from baseline to 1 year. RESULTS: The cumulative incidence of the renal composite outcome was significantly higher in group 1 with lowest tertile of plasma ACE2 (p=0.040). Group 2 with middle and highest tertile was associated with better renal outcomes in the crude Cox regression model adjusted by age and sex (HR 0.56, 95% CI 0.31 to 0.99, p=0.047). Plasma ACE2 levels demonstrated a significant association with 30% decrease in ACR (OR 1.46, 95% CI 1.044 to 2.035, p=0.027) after adjusting for age, sex, systolic blood pressure, hemoglobin A1c, and eGFR. CONCLUSIONS: Higher baseline plasma ACE2 levels in DKD were protective for development and progression of albuminuria and associated with fewer renal end points, suggesting plasma ACE2 may be used as a prognosis marker of DKD. TRIAL REGISTRATION NUMBER: UMIN000011525.

A 68-year-old woman was admitted to our hospital because of a rapid progression of renal dysfunction with positive myeloperoxidase antineutrophil cytoplasmic antibody and was diagnosed with rapidly progressive glomerulonephritis associated with microscopic polyangiitis (MPA). Severe right rectus sheath hematoma (RSH) bleeding from the inferior epigastric artery developed after starting hemodialysis, which required 4 transarterial embolizations due to recurrent bleeding. After additional treatment with methylprednisolone pulse therapy and rituximab, no rebleeding occurred. Although the giant hematoma reached the pelvis, it shrank spontaneously without any intervention. Nontraumatic RSH should therefore be considered when treating patients with multiple risk factors.

Abstract

Objectives: To access the real-world clinical management of physicians who treat Takayasu arteritis (TAK) and giant cell arteritis (GCA) after the publication of the Japanese Circulation Society (JCS) 2017 Guidelines for the Management of Vasculitis Syndrome.

Methods: This descriptive, cross-sectional study utilized self-administered electronic questionnaires, which were answered in February 2022 by physicians treating TAK or GCA and registered with Macromill Inc.

Results: The 329 survey respondents comprised 110 cardiologists, 110 rheumatologists, 34 cardiovascular surgeons, 24 surgeons, 35 internal medicine physicians, 13 nephrologists, and 7 pediatricians. The 2017 JCS Guidelines were the most commonly referenced information source for resolving clinical questions, accessed by 70% of respondents. Ophthalmoscopy was performed in only 50% of patients with TAK, and in 70% for GCA. The median percentages of patients who underwent 18F-fluorodeoxyglucose-positron emission tomography/computed tomography for TAK and GCA patients were 23% and 20% at diagnosis, respectively, and 10% each at follow-up within 12 months. Tocilizumab was the most frequently used medication in combination with glucocorticoids for both TAK and GCA, especially in remission induction therapy for relapsed patients.

Conclusions: The majority of physician treating TAK and GCA referred to the 2017 JCS guidelines. This report clarified the current clinical practice for large vessel vasculitis in Japan, providing information for the next revision of the guidelines.

Fabry disease (FD) is an X-linked disorder resulting in a deficiency of α-galactosidase A (GLA) activity. The R112H mutation of GLA is relatively common in Japanese FD patients, characterized by a late-onset phenotype, almost normal to mild lyso-Gb3 elevation, and mild clinical symptoms, despite low GLA activity. This is due to the structural features of the R112H GLA protein. We herein report the case of a 42-year-old male patient with late-onset FD with a R112H mutation. The patient exhibited only renal involvement with no other organ damage and was successfully treated with galactosidase beta and subsequent migalastat for approximately 10 years. Especially, migalastat was clinically effective in normalizing plasma lyso-Gb3 levels and inhibiting the progression of renal damage associated with FD. Therefore, the use of migalastat in the FD patients with R112H mutation is highly recommended based on this case report.

BACKGROUND: Takayasu arteritis, affecting primarily young women, damages large arteries and organs. We examined the impact of disease duration and sex on organ damage and quality of life using Japan's Intractable Disease Registry.Methods and Results: After refining data, 2,013 of 2,795 patients were included in the study. Longer disease duration was related to a lower prevalence of disease activity symptoms, a higher prevalence of organ damage, and a higher proportion of patients requiring nursing care. Compared with men, women tended to have an earlier onset age, exhibiting longer disease duration. A higher proportion of women had aortic regurgitation and required nursing care. The proportion of female patients in employment was lower than that of the general female population, whereas no difference was observed between male patients and the general male population. Logistic regression analysis revealed that age at surveillance, brain ischemia, visual impairment/loss, and ischemic heart disease were significant factors associated with high nursing care needs (Level ≥2, with daily activity limitations). CONCLUSIONS: Early diagnosis and effective treatment, particularly to prevent brain ischemia, visual impairment, and ischemic heart disease, may improve the quality of life of patients with Takayasu arteritis, especially women.

RATIONALE & OBJECTIVE: Assessment of kidney biopsies provides crucial information for diagnosis and disease activity, as well as prognostic value. Kidney-biopsy specimens occasionally contain veno-muscular complex (VMC), which consists of muscle tissues around the kidney venous system in the corticomedullary region. However, the role of VMC and the clinical significance of VMC variants are poorly understood. In the present study, we investigated kidney prognostic values of VMC variants. STUDY DESIGN: Retrospective cohort study. SETTING & PARTICIPANTS: Among 808 patients who underwent a kidney biopsy from 2011 to 2019, 246 patients whose kidney biopsy specimens contained VMC were enrolled. PREDICTORS: VMC variants; inflammatory-VMC (an infiltration of ≥80 inflammatory cells/mm2-VMC area) and VMC hypertrophy (hyper-VMC, a VMC average width ≥850 μm), and the interstitial fibrosis/tubular atrophy (IFTA) score. OUTCOMES: A decline in estimated glomerular filtration rate (eGFR) ≥40% from the baseline or commencement of kidney replacement therapy. ANALYTICAL APPROACH: Cox proportional hazards model. RESULTS: Among 246 patients with data on VMC, mean baseline eGFR was 56.0±25.6 ml/min per 1.73 m2; 80 had high inflammatory-VMC, and 62 had VMC hypertrophy. There were 51 kidney events over median follow-up of 2.5 years. We analyzed 2 VMC variants. Multivariable logistic regression analysis revealed that eGFR negatively correlated with the presence of both inflammatory-VMC and hyper-VMC. A Cox proportional hazards analysis revealed that inflammatory-VMC (but not hyper-VMC) was independently associated with the primary outcome after adjustments for known risk factors of progression, including proteinuria, eGFR, and the interstitial fibrosis/tubular atrophy (IFTA) score (hazard ratio, 1.97; 95% confidence interval, 1.00-3.91). LIMITATIONS: Single-center study and small sample size. CONCLUSIONS: Assessment of inflammatory-VMC provides additional kidney prognostic information to known indicators of kidney disease progression in patients who undergo kidney biopsy. PLAIN-LANGUAGE SUMMARY: Assessment of kidney biopsies provides crucial information for diagnosis, disease activity, and prognostic value. Kidney-biopsy specimens occasionally contain veno-muscular complex (VMC), which consists of muscle tissues around the kidney venous system. Currently, the role of VMC in kidney health and diseases and the clinical significance of VMC variants are poorly understood. In the present study, we have shown that an infiltration of ≥80 inflammatory cells/mm2-VMC area (inflammatory-VMC) is independently associated with kidney disease progression after adjustments for known risk factors of progression. Therefore, assessment of inflammatory-VMC provides additional kidney prognostic information to known indicators of kidney disease progression in patients who undergo kidney biopsy.

BACKGROUND: Abdominal aortic aneurysm (AAA) is an arterial disease characterized by dilatation of the aortic wall. It has been suggested that neutrophil counts and neutrophil elastase activity are associated with AAA. We investigated whether a neutrophil elastase (NE) inhibitor, sivelestat (Siv), had a protective effect against angiotensin II (AngII)-induced AAAs. METHODS: Male apolipoprotein E-deficient mice were assigned into 3 groups: Vehicle+saline, AngII+saline, and AngII+Siv. All mice were administered intraperitoneally with either Siv or vehicle twice daily after AngII infusion. RESULTS: In the 4-week AngII infusion study, plasma NE concentration (p=0.041) and its activity (p=0.011) were elevated by AngII. These increases were attenuated by Siv (concentration:p=0.010, activity:p=0.027). Further, plasma elastase activity was closely correlated with aortic width (R=0.6976, p<0.001). In the 1-week AngII infusion study, plasma and tissue elastase activity increased by AngII (plasma:p=0.034, tissue:p<0.001), but were reduced by Siv (plasma:p=0.014, tissue:p=0.024). AngII increased aortic width (p=0.011) but was attenuated by co-administration of Siv (p=0.022). Moreover, Siv decreased the incidence of AAAs (p=0.009). Elastin fragmentation induced by AngII was reduced by Siv. Many inflammatory cells that were either CD68 or Gr-1 positive were observed in the AngII+saline group, whereas few inflammatory cells were accumulated in the AngII+Siv group. MMP-2 and MMP-9 were enhanced by AngII, but were reduced by Siv. In vitro, MMP-2 activity was induced by human NE (medium:p<0.001, cells:p=0.001), which was attenuated by co-incubation of Siv in medium (p<0.001) and protein of human aortic smooth muscle cells (p=0.001). CONCLUSION: Siv attenuated AngII-induced AAA through the inhibition of NE.
