Serum levels of growth hormone (GH) and insulin-like growth factor (IGF)-I are crucial in the diagnosis and management of GH-related diseases. However, these levels are affected by nutritional and metabolic status. To elucidate the correlations between GH and IGF-I in various conditions, a retrospective analysis was performed for adult patients in which GH levels were examined by general practitioners during the period from January 2019 to December 2021. Of 642 patients, 33 patients were diagnosed with acromegaly, 21 were diagnosed with GH deficiency (GHD), and 588 were diagnosed with non-GH-related diseases (NGRD). In contrast to the positive correlations found between the levels of GH and IGF-I in patients with acromegaly (R=0.50; P<0.001) and patients with GHD (R=0.39; P=0.08), a negative correlation was found in the NGRD group (R=-0.23; P<0.001). In that group, the results of multivariable analysis showed that GH levels were predominantly influenced by gender and body mass index (BMI), whereas IGF-I levels were modulated by albumin in addition to age and GH. Of note, in the NGRD group, there was an enhanced negative correlation between GH and IGF-I under conditions of BMI < 22 and albumin < 4.0 g/dL (R=-0.45; P<0.001), and the negative correlation between GH and IGF-I was reinforced by excluding patients with other pituitary diseases and patients taking oral steroids (R=-0.51; P<0.001 and R=-0.59; P<0.001, respectively). Collectively, the results indicate that attention should be given to the presence of a negative correlation between serum levels of GH and IGF-I, especially in lean and low-nutritious conditions.

Intravesical Bacillus Calmette-Guérin (BCG) instillation is an established immunotherapy for superficial bladder cancer. Herein, we describe a case of disseminated BCG infection that developed immediately after the first BCG injection. A 76-year-old man diagnosed with non-invasive bladder cancer underwent intravesical BCG instillation; he developed high fever and systemic arthralgia later that night. General examination did not reveal any infectious sources, and a combination therapy of isoniazid, rifabutin, and ethambutol was initiated after collecting his blood, urine, bone marrow, and liver biopsy samples for mycobacterial cultures. Three weeks later, Mycobacterium bovis was detected in the urine and bone marrow samples, and pathological investigation of liver biopsy revealed multiple small epithelial granulomas with focal multinucleated giant cells, leading to a diagnosis of disseminated BCG infection. The patient recovered after long-term antimycobacterial therapy without remarkable sequelae. Most cases of disseminated BCG infection occur after several doses of BCG injections, and its onset reportedly varies among cases, ranging from a few days to several months. The present case was notable as disease onset was observed only a few hours after the first BCG injection. Although rare, development of disseminated BCG infection should be considered as a differential diagnosis in patients at any time after intravesical BCG instillation therapy.

OBJECTIVES: This study aimed to evaluate the antiviral effects and safety of nafamostat in early-onset patients with coronavirus disease 2019 (COVID-19). METHODS: In this exploratory multicenter randomized controlled trial, patients were assigned to three groups within 5 days of symptom onset, with 10 participants in each group: nafamostat at either 0.2 mg/kg/h or 0.1 mg/kg/h or a standard-of-care group. The primary endpoint was area under the curve for decrease in SARS-CoV-2 viral load in nasopharyngeal samples from baseline to day 6. RESULTS: Of the 30 randomized patients, 19 received nafamostat. Overall, 10 patients received low-dose nafamostat, 9 patients received high-dose nafamostat, and 10 received standard-of-care. The detected viruses were Omicron strains. The regression coefficient for area under the curve for decrease in viral load as the response variable and nafamostat dose per body weight as the explanatory variable showed a significant relationship of -40.1 (95% confidence interval, -74.1 to -6.2; p=0.022). Serious adverse events were not observed in either group. Phlebitis occurred in approximately 50% of patients treated with nafamostat. CONCLUSIONS: Nafamostat exerts virus load-reducing effects in patients with early-onset COVID-19.

We usually do not consider sarcoidosis routinely for the differential diagnosis of acute arthritis, however, up to 15 to 25% of sarcoidosis complicate arthritis, typically in ankle joints. Sarcoid arthritis is reported to occur mainly in young northern Europe women, whereas this case intimate that we should take sarcoidosis into account as the differential diagnosis of ankle arthralgia also among Asian men especially when combining upper respiratory symptoms.

Granulicatella species are rare, nutritionally variant streptococci that cause infective endocarditis. Their clinical and microbiological characteristics remain unknown. We reviewed five years of Granulicatella cases in our hospital database (Jan 2017-Jun 2022), finding 6 Granulicatella adiacens cases and 1 Granulicatella elegans case. Clinical backgrounds and bacteremia sources were diverse; 3 cases developed polymicrobial bacteremia. Antimicrobial testing showed non-susceptibility to penicillin G in 4 of 7 cases (57.1%), and high susceptibility to carbapenems and vancomycin in all cases. Determining optimal antibiotic therapy for Granulicatella infections is vital in this era of antimicrobial resistance.

Cryptococcal meningitis is a critical disease that occasionally involves immunosuppressed patients. We herein report a 79-year-old Japanese man who received low-dose prednisolone therapy for neurosarcoidosis and panhypopituitarism. He presented a 10-day history of a fever and altered mental status. The FilmArray® Meningitis/Encephalitis Panel and serum cryptococcal antigen tests were both negative, but the cerebrospinal fluid sample became positive for Cryptococcus neoformans after seven-day incubation. After the diagnosis of cryptococcal meningitis, we successfully treated the patient with a recommended treatment regimen. When an immunocompromised patient presents with a subacute fever accompanying any central nervous symptoms, cryptococcal meningitis should be screened for.

BACKGROUND: Some COVID-19 patients develop life-threatening disease accompanied by severe pneumonitis. Teprenone induces expression of heat-shock proteins (HSPs) that protect against interstitial pneumonia in preclinical models. We explored whether teprenone prevented worsening of COVID-19 infections. METHODS: This open-label, randomized, pilot phase 2 clinical trial was conducted at five institutions in Japan. We randomized patients hospitalized for COVID-19 with fever to teprenone or no-teprenone groups in a 1:1 ratio. We stratified patients by sex, age < and ≥ 70 years and the existence (or not) of complications (hypertension, diabetes, ischemic heart disease, chronic pulmonary disease and active cancer). No limitation was imposed on other COVID-19 treatments. The primary endpoint was the intubation rate. RESULTS: One hundred patients were included, 51 in the teprenone and 49 in the no- teprenone groups. The intubation rate did not differ significantly between the two groups: 9.8% (5/51) vs. 2.0% (1/49) (sub-hazard ratio [SHR] 4.99, 95% confidence interval [CI]: 0.59-42.1; p = 0.140). The rates of intra-hospital mortality and intensive care unit (ICU) admission did not differ significantly between the two groups: intra-hospital mortality 3.9% (2/51) vs. 4.1% (2/49) (hazard ratio [HR] 0.78, 95%CI: 0.11-5.62; p = 0.809); ICU admission 11.8% (6/51) vs. 6.1% (3/49) (SHR 1.99, 95%CI: 0.51-7.80; p = 0.325). CONCLUSION: Teprenone afforded no clinical benefit. TRIAL REGISTRATION: Japan Registry of Clinical Trials jRCTs061200002 (registered on 20/May/2020).

Abstract

Amid the Coronavirus Disease 2019 pandemic, we aimed to demonstrate the accuracy of the fingertip whole blood sampling test (FWT) in measuring the antibody titer and uncovering its dynamics shortly after booster vaccination. Mokobio SARS-CoV-2 IgM &amp; IgG Quantum Dot immunoassay (Mokobio Biotechnology R&amp;D Center Inc., MD, USA) was used as a point-of-care FWT in 226 health care workers (HCWs) who had received two doses of the BNT162b2 mRNA vaccine (Pfizer-BioNTech) at least 8 months prior. Each participant tested their antibody titers before and after the third-dose booster up to 14-days. The effect of the booster was observed as early as the fourth day after vaccination, which exceeded the detection limit (&gt; 30,000 U/mL) by 2.3% on the fifth day, 12.2% on the sixth day, and 22.5% after the seventh day. Significant positive correlations were observed between the pre- and post-vaccination (the seventh and eighth days) antibody titers (correlation coefficient, 0.405; p &lt; 0.001). FWT is useful for examining antibody titers as a point-of-care test. Rapid response of antibody titer started as early as the fourth day post-vaccination, while the presence of weak responders to BNT162b2 vaccine was indicated.

Candida dubliniensis phenotypically mimics Candida albicans in its microbiological features; thus, its clinical characteristics have yet to be fully elucidated. Here we report the case of a 68-year-old Japanese man who developed C. dubliniensis fungemia during treatment for severe coronavirus disease 2019 (COVID-19). The patient was intubated and received a combination of immunosuppressants, including high-dose methylprednisolone and two doses of tocilizumab, as well as remdesivir, intravenous heparin, and ceftriaxone. A blood culture on admission day 11 revealed Candida species, which was confirmed as C. dubliniensis by mass spectrometry. An additional sequencing analysis of the 26S rDNA and ITS regions confirmed that the organism was 100% identical to the reference strain of C. dubliniensis (ATCC MYA-646). Considering the simultaneous isolation of C. dubliniensis from a sputum sample, the lower respiratory tract could be an entry point for candidemia. Although treatment with micafungin successfully eradicated the C. dubliniensis fungemia, the patient died of COVID-19 progression. In this case, aggressive immunosuppressive therapy could have caused the C. dubliniensis fungemia. Due to insufficient clinical reports on C. dubliniensis infection based on definitive diagnosis, the whole picture of the cryptic organism is still unknown. Further accumulation of clinical and microbiological data of the pathogen is needed to elucidate their clinical significance.

We presented a case of primary bone lymphoma (PBL) which demonstrated fever of unknown origin. Although the diagnosis of PBL is difficult, up to 11% of patients with fever of unknown origin were later diagnosed with PBL, which suggests that there may be many cases of misdiagnosis. This case study emphasizes the importance of careful diagnosis for fever of unknown origin especially when the patient has bone pain.

After the acute phase of COVID-19, some patients have been reported to have persistent symptoms including general fatigue. We have established a COVID-19 aftercare clinic (CAC) to provide care for an increasing number of these patients. Here, we report the case of a 36-year-old man who developed post-COVID fatigue after acute infection with SARS-CoV-2. In the acute phase of COVID-19, the patient's fever resolved within four days; however, general fatigue persisted for three months, and he visited our CAC 99 days after the initial infection. Examination revealed a high Aging Male's Symptoms (AMS) score of 44 and low free testosterone (FT) level of 5.5 pg/mL, which meet the Japanese criteria of late-onset hypogonadism (LOH) syndrome. Imaging studies revealed an atrophic pituitary in addition to fatty liver and low bone mineral density. Anterior pituitary function tests showed a low follicle-stimulating hormonelevel and delayed reaction of luteinizing hormone (LH) after gonadotropin-releasing hormone (GnRH) stimulation, indicating the possibility of hypothalamic hypogonadism in addition to primary hypogonadism seen in patients with post-COVID-19 conditions. After the initiation of Japanese traditional medicine (Kampo medicine: hochuekkito followed by juzentaihoto), the patient's symptoms as well as his AMS score and serum FT level were noticeably improved. Furthermore, follow-up tests of GnRH stimulation revealed improvements in LH responsiveness. Although many patients have been reported to meet the criteria of ME/CFS such as our case, we emphasize the possibility of other underlying pathologies including LOH syndrome. In conclusion, LOH syndrome should be considered a cause of general fatigue in patients with post-COVID-19 conditions and herbal treatment might be effective for long COVID symptoms due to LOH (264 words).

Netherton's syndrome, a rare congenital disorder, is clinically characterized by chronic dermatologic disorders such as ichthyosiform erythroderma and ichthyosis linearis circumflexa. Curable treatment is yet to be established, and corticosteroid ointment is required to maintain good dermatological condition. Because of the permanent skin barrier impairment, patients with Netherton's syndrome are considered to be vulnerable to cutaneous infections. However, its clinical characteristics are yet to be elucidated due to the limited number of reported cases. Herein, we describe the clinical course of a patient who developed persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia. A 19-year-old Japanese woman who had been diagnosed with Netherton's syndrome in her infancy and had been applying topical corticosteroid agents all over her body since her then, was referred to our hospital because of persistent MRSA bacteremia and secondary adrenal insufficiency. The patient was diagnosed with a central line-associated bloodstream infection and was appropriately treated with antibiotics and corticosteroid therapies. We assume that the damaged skin barrier due to the congenital dermatological disorder causes a disruption in the normal bacterial flora of the skin, leading to the invasion of harmful bacteria, such as S. aureus. In addition, internal (humoral immunodeficiency by decreased antibody against bacterial polysaccharide antigens) and external (prolonged and systemic use of corticosteroid ointment) factors bring about an immunodeficiency state in such patients. We highlight that in the absence of radical treatment, clinicians need to recognize that patients with Netherton's syndrome are vulnerable to bacterial infections owing to the mixture of immunosuppressive factors.

BACKGROUND: We analyzed data from COVID-19 patients in Japan to assess the utility of the 4C mortality score as compared with conventional scorings. METHODS: In this multicenter study, COVID-19 patients hospitalized between March 2020 and June 2021, over 16 years old, were recruited. The superiority for correctly predicting mortality and severity by applying the receiver operating characteristic (ROC) curve was compared. A Cox regression model was used to compare the length of hospitalization for each risk group of 4C mortality score. RESULTS: Among 206 patients, 21 patients died. The area under the curve (AUC) (95% confidential interval (CI)) of the ROC curve for mortality and severity, respectively, of 4C mortality scores (0.84 (95% CI 0.76-0.92) and 0.85 (95% CI 0.80-0.91)) were higher than those of qSOFA (0.66 (95% CI 0.53-0.78) and 0.67 (95% CI 0.59-0.75)), SOFA (0.70 (95% CI 0.55-0.84) and 0.81 (95% CI 0.74-0.89)), A-DROP (0.78 (95% CI 0.69-0.88) and 0.81 (95% CI 0.74-0.88)), and CURB-65 (0.82 (95% CI 0.74-0.90) and 0.82 (95% CI 0.76-0.88)). For length of hospitalization among survivors, the intermediate- and high- or very high-risk groups had significantly lower hazard ratios, i.e., 0.48 (95% CI 0.30-0.76)) and 0.23 (95% CI 0.13-0.43) for discharge. CONCLUSIONS: The 4C mortality score is better for estimating mortality and severity in COVID-19 Japanese patients than other scoring systems.

Coronavirus disease 2019 (COVID-19) has been spreading worldwide with unprecedented rapidity. Staphylococcus aureus is reported to frequently cause bacterial complications in patients with COVID-19. We herein present two additional cases of S. aureus pneumonia involving such patients. The first case was an obese 48-year-old man without any particular underlying diseases. The second case was another patient, a 72-year-old man, with hypertension, dyslipidemia, and steatohepatitis. Both patients developed methicillin-susceptible S. aureus pneumonia in the clinical course of COVID-19, to which antibiotic therapy with cefazolin was effectively administered. Through these cases, we emphasize that S. aureus secondary infections should be well cared with a high degree of caution in a case of critically ill COVID-19 patients.

Subclinical hypothyroidism (SCH) is diagnosed when serum thyrotropin (TSH) is elevated despite a normal thyroxine level and is known to increase the risk of metabolic disorders. This study was conducted to identify potential laboratory markers suspicious for latent SCH. We retrospectively reviewed 958 outpatients in whom thyroid functions had been examined. Eighty-five (9.1%) of the 939 analyzed subjects had SCH (73% females). In the SCH group, median serum TSH and FT4 levels were 5.04 μU/ml and 1.19 ng/dl, respectively, and auto-thyroid antibodies were detected in 53.8% of patients. SCH group patients were significantly older than patients in the euthyroid group, while there was no intergroup difference in BMI. However, 56.5% of the SCH patients were asymptomatic. In the SCH group, serum aspartate aminotransferase and low-density lipoprotein cholesterol (LDL-C) levels were significantly higher, and the estimated glomerular filtration rate (eGFR) was significantly lower than in the euthyroid group. Among patients less than 65 years of age, SCH patients tended to have lower eGFR and higher LDL-C than euthyroid patients. Age-dependent reductions of red blood cells and serum albumin were more prominent in the SCH than the euthyroid group. Biochemical changes with aging are useful as potential clues for suspecting latent SCH.

INTRODUCTION: The novel coronavirus disease 2019 (COVID-19) has emerged as a global pandemic, and the United States and European authorities established criteria for the release of COVID-19 patients from isolation in October 2020. However, a huge discrepancy exists between the hospital-discharge protocol for COVID-19 patients and the release of patients from in-hospital isolation. Our initially proposed criteria for in-hospital release from isolation was not adhered to by healthcare workers (HCWs) due to prevailing concerns regarding disease infectivity. Herein, we report difficulties encountered in attempting to establish a common understanding of the management of emerging infections. METHODS: We performed a Google Form-based questionnaire survey targeting HCWs from Okayama University Hospital, Japan, via e-mail on January 21-28, 2021. The anonymous investigation required respondents to provide information regarding their background as well as perceptions regarding the requirement, level of understanding, and readiness for developing release criteria. RESULTS: We obtained 150 eligible responses, including 57 (38.0%) from medical doctors and 53 (35.3%) from nurses. Most HCWs managing COVID-19 patients advocated for the implementation of the criteria, whereas those not working in that capacity did not (p<0.001). Over half of the HCWs indicated discomfort at seeing COVID-19 patients transitioning to general management even after meeting the criteria. CONCLUSIONS: It was challenging to establish a common understanding regarding the ideal criteria for in-hospital release of COVID-19 patients from isolation in our hospital. The dissemination of our experiences and multifaceted discussions with HCWs would be of great value as a countermeasure against the emergent pandemic.

The coronavirus disease 2019 (COVID-19) pandemic has posed a significant challenge to the modern healthcare system and led to increased burnout among healthcare workers (HCWs). We previously reported that HCWs who engaged in COVID-19 patient care had a significantly higher prevalence of burnout (50.0%) than those who did not in November 2020 (period 1). We performed follow-up surveys in HCWs in a Japanese national university hospital, including basic demographics, whether a participant engaged in care of COVID-19 patients in the past 2 weeks, and the Maslach Burnout Inventory in February 2021 (period 2) and May 2021 (period 3). Periods 1 and 3 were amid the surges of COVID-19 cases, and period 2 was a post-surge period with a comparatively small number of COVID-19 patients requiring hospitalization. Response rates to the surveys were 33/130 (25.4%) in period 1, 36/130 (27.7%) in period 2, and 56/162 (34.6%) in period 3, respectively. While no consistent tendency in the prevalence of burnout based on variables was observed throughout the periods, the prevalence of burnout tends to be higher in periods 1 and 3 in those who engaged in COVID-19 patient care in the last 2 weeks (50.0%, 30.8%, 43.1% in period 1, 2, and 3, respectively). Given the prolonged pandemic causing stigmatization and hatred against HCWs leading to increased prevalence of burnout, high-level interventions and supports are warranted.

Urinary catecholamines (CAs) have been examined for the screening of pheochromocytomas. The decision to perform screening is based on symptoms suggesting secondary hypertension or hyperactivities of the sympathetic nervous system. To elucidate the usefulness of urinary fractions and ratios of CAs, 79 patients in whom 24-h excretions of urinary CAs including adrenaline (AD), noradrenaline (NA) and dopamine (DA) had been examined from 2015 until 2020 were retrospectively analyzed. There were no significant differences in urinary CA levels between two age groups, gender groups and two BMI groups. Patients with histories of preexisting hypertension and diabetes showed significantly higher levels of urinary NA excretion, and the urinary ratio of NA/DA was also increased in the patients with a history of hypertension. Heart rate (HR) was significantly correlated with the urinary ratio of NA/DA. Serum free thyroxine (FT4) concentration and ratio of FT4/thyrotropin (TSH) were correlated with the level of urinary AD. The levels of TSH and FT4/TSH showed negative and positive correlations, respectively, with the urinary NA/DA ratio. Thus, increases of HR are related to the enhanced conversion of DA to NA and increased thyroid hormones are involved in the increase in urinary AD and the conversion of DA to NA. History of lifestyle-related diseases and changes of HR and thyroid functions need to be considered for the evaluation of urinary CAs and their ratios.

Introduction The long-term clinical course, prognosis, and optimal management of symptoms and conditions after the acute phase of coronavirus disease 2019 (COVID-19) remain to be elucidated. The purpose of this study was to clarify the characteristics of patients referred to a COVID-19 aftercare (CAC) clinic established at a tertiary academic hospital in Japan. Methods This study was a descriptive case series study. All patients who visited the CAC clinic between February 15 and September 17 in 2021 were included. Patients' background, chief complaints, and clinical courses after the onset of COVID-19 were described. Results A total of 87 Japanese patients (median age, 40.0 years; interquartile range [IQR], 26.5-53.0 years; 52.9% women) were referred to the CAC clinic. The median interval between the onset of COVID-19 and the visit to the clinic was 79.0 (IQR, 52.5-112.0) days. Referral sources were hospitals (36 patients), clinics (47 patients), a local healthcare center (3 patients), and other (1 patient). The most common chief complaint was general fatigue (50.4%) followed by dysosmia (28.7%), dysgeusia (26.4%), hair loss (18.4%), headache (17.2%), dyspnea (16.1%), and dyssomnia (13.1%). Respiratory symptoms were common in the early stages of the disease but were less common as the chief complaints when visiting the clinic. On the other hand, neurological, psychiatric, and extremity symptoms were predominant one month after the onset of COVID-19. Conclusions Regardless of the severity in the acute phase, patients visiting our CAC clinic suffered from a variety of symptoms. General physicians skilled in using a comprehensive approach would be optimal to see patients with such complex symptoms.

国際化を背景に、在日外国人も新型コロナウイルス感染症(COVID-19)に罹患しているが、本邦でその診療上の課題に関する文献はない。2020年2月からの1年間に岡山大学病院総合内科・総合診療科に入院した、外国人COVID-19患者全5人を対象として、患者背景や言語状況、入院中のトラブルや解決策について診療録から抽出した。全員が日本語の書字・読字が全く不能であり、うち1人は日常会話も困難で電話医療通訳サービスを要したが、担当医や看護師に加えて、国際診療支援センターや臨床栄養部、精神科などと連携することで隔離解除まで入院継続が可能であった。COVID-19では本人の希望に沿わない入院や予定外入院のため、通常の外国人診療に比して負担・課題が大きい。特に言語面での制約は、隔離管理下での意思疎通や同意書の取得などの面で障壁となることが明らかとなった。院内組織の連携と、病院を超えた情報共有による病軟な対応が重要である。(著者抄録)

Objectives Vitamin D deficiency, which is common worldwide, increases the risks of falls and fractures and can lead to increased morbidity and mortality. However, the clinical utility and relevance of vitamin D activation remain unknown. The aim of the present study was to clarify the clinical usefulness of serum 1,25-dihydroxyvitamin D (1,25D)/25-hydroxyvitamin D (25D) ratio for assessment of the extent of bone metabolism. Methods We retrospectively screened data for 87 patients whose serum 1,25D and 25D levels were measured. Eight patients who were taking vitamin D preparations were excluded, and data for 79 patients (33 males and 46 females) were analyzed. Since menopausal status can be associated with serum vitamin D level, we divided the patients by gender and divided the female patients into two groups at the age of 50 years. Results The median serum 1,25D/25D ratio was significantly lower in males than in females, with the most considerable difference in all males [4.1 (interquartile range: 2.3-5.8) × 10-3] versus elderly females (aged ≧50 years) [7.9 (3.3-10.1) × 10-3). Main disorders were endocrine (30.6%), inflammatory (18.5%), and bone-related (16.7%) disorders. The ratios of serum 1,25D/25D had significant negative correlations with femoral dual-energy X-ray absorptiometry % young adult mean (DEXA %YAM) (R=-0.35) and lumbar DEXA %YAM (R=-0.32). Significant correlations were found between the 1,25D/25D ratio and serum levels of inorganic phosphate (iP), parathyroid hormone, and alkaline phosphatase (ALP). The 1,25D/25D ratio had gender-specific characteristics: the ratio was significantly correlated with age in males (R=-0.49), while it was significantly correlated with BMI in females (R=0.34). Conclusions The results of this study suggested that vitamin D activity is negatively correlated with bone mineral density, being reduced in aged males but enhanced in obese females.

Primary Sjögren's syndrome (SS) is an autoimmune disease that usually affects the exocrine glands in mid-dle-aged women. Fifteen percent of SS patients experience severe systemic extraglandular complications, and pleuritis is one of the rare complications of SS. We report the case of an elderly Japanese man who initially pre-sented with a prolonged fever and chest pain and was finally diagnosed with primary SS-associated pleuritis. Of the nine reported cases of primary SS that initially presented with pleuritis, up to six cases were elderly males. This case highlights the complication of pleuritis among elderly males with primary SS.

Pregnancy was reported to be a risk factor for coronavirus disease 2019 (COVID-19), with an increased risk for premature birth. Corticosteroids and remdesivir are used for patients with COVID-19; however, there is no established treatment for these patients. In particular, the effective management of pregnant, critically ill patients with COVID-19 remains unknown. We describe a 34-year-old, critically ill woman at 30 weeks of gestation with COVID-19, who was successfully treated with remdesivir and combined high-dose betamethasone (12 mg/day for two days) and methylprednisolone (125 mg/day for three days) followed by steroid tapering. During treatment, fetal biophysical profile scores on obstetric ultrasound were normal; her pregnancy course progressed well. Since high-dose corticosteroids improve fetal lung maturation and as well as cytokine storm due to COVID-19, this case provides an insight into the management of pregnant COVID-19 patients.

CASE PRESENTATION: A 49-year-old Asian male, who had undergone hemodialysis for >16 years, complained of a fever, dysgeusia and dysosmia, and was diagnosed with COVID-19 pneumonia based on severe acute respiratory syndrome coronavirus 2 polymerase chain reaction (SARS-CoV-2 PCR) and computed tomography (CT). Treatment was started with oral favipiravir and ciclesonide inhalation. On the 10th day of treatment, the patient had a persistent high fever and a chest CT showed exacerbation of pneumonia, so dexamethasone was intravenously started. He was discharged after confirming two consecutive negative SARS-CoV-2 PCR tests. Three months after COVID-19 treatment, a SARS-CoV-2 PCR test was negative and he underwent a deceased donor kidney transplantation. Basiliximab induction with triple drug immunosuppression consisting of extended-release tacrolimus, mycophenolate mofetil and prednisolone, which is our regular immunosuppression protocol, was used. He was discharged on postoperative day 18 without the need for postoperative hemodialysis or any complications. The serum creatinine level was 1.72 mg/dL 95 days postoperatively and he had a favorable clinical course that was similar to deceased donor kidney recipients without a history of SARS-CoV-2 infection. CONCLUSION: We report the first case of a kidney transplantation after COVID-19 treatment in Japan and the fourth case globally. We would like to provide information about our successful case due to the anticipated increase in similar candidates in the near future.

The gold standard for the diagnosis of coronavirus disease 2019 (COVID-19) is a nucleic acid detection test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may occasionally reveal false-positive or false-negative results. Herein, we describe a case of a patient infected with human coronavirus NL63 (HCoV-NL63) who was falsely diagnosed with COVID-19 using the Ampdirect™ 2019-nCoV detection kit (Shimadzu Corporation, Japan) and SARS-CoV-2 Detection Kit (TOYOBO co., ltd.), and was admitted to a COVID-19 hospital ward. We suspected a cross-reaction between HCoV-NL63 and SARS-CoV-2; however, the reported genome sequences of HCoV-NL63 and N1/N2 primers for SARS-CoV-2 do not correspond. Thus, the PCR result was supposed to be a false positive possibly due to contamination or human error. Although the issue of a false-negative result has been the focus of much attention to prevent the spread of the disease, a false positive is fraught with problems as well. Physicians should recognize that unnecessary isolation violates human rights and a careful diagnosis is indispensable when the results of laboratory testing for COVID-19 are unclear. Generally, in cases such as a duplicate PCR test was partially positive, either N1 or N2 alone was positive, PCR testing for two or more target regions resulted in a positive only for single region, a high cycle threshold >35 was obtained, a false positive should be suspected. Especially, when these conditions coincide, we should recognize the high likelihood of a false positive.

Granulocyte colony-stimulating factor (G-CSF) is a relatively new drug that is used for recovery of chemotherapy-associated neutropenia. It is known to cause bone pain, headache and fatigue as side-effects; however, large-vessel vasculitis is extremely rare and its relation with G-CSF remains unknown. We describe a 49-year-old woman in whom arteritis developed after chemotherapy and subsequent G-CSF administration. She had experienced pinealoma 3 months ago and received surgery and chemotherapy, leading to neutropenia. After administration of lenograstim at 100 μg/day for 1 week, high fever and neck pain appeared. White blood cell count and serum levels of C-reactive protein and interleukin-6 were increased to 37,930/μL, 23.71 mg/dL, and 241 pg/mL, respectively. Contrast-enhanced computed tomography revealed thickened walls of large vessels including the bilateral common carotid artery (CCA), right brachiocephalic artery, and ascending aorta. Ultrasonography showed wall thickening of the CCA (maximum of intima media thickness: right, 2.9 mm; left, 3.2 mm). As differential diagnoses, infection, chemotherapy, autoimmune diseases, and cancer were considered other than G-CSF. Blood culture tests, lumbar puncture, β-D-glucan tests, and tests for viral antibodies indicated no active infection, and autoantibodies were negative. Empirical antibiotic therapy was ineffective. The score of Naranjo's algorithm to lenograstim was 6, indicating "probable" causality. Considering the clinical course and test results, we made a diagnosis of G-CSF-associated arteritis and commenced glucocorticoid therapy, which drastically improved the symptoms and inflammation. Clinicians should be aware of this uncommon but significant complication of GCS-F administration, for which glucocorticoid treatment can be a useful therapeutic option.

Immune checkpoint inhibitors (ICIs) such as nivolumab and ipilimumab are emerging agents for the treatment of cancers including melanoma. ICIs are known to cause immune-related adverse events (irAEs), including the development of enterocolitis, dermatitis, and nephritis. However, ICI-induced pancreatitis has seldom been reported, and its pathophysiology and clinical importance remain largely unknown. We describe a 76-year-old man with melanoma who developed acute pancreatitis without abdominal pain after immunotherapy with nivolumab and ipilimumab. The patient was referred due to 2-week-long general fatigue, anorexia, and dermatitis after his second immunotherapy. Laboratory examinations in serum showed high inflammation and renal dysfunction. Plain computed tomography (CT) on admission showed no new lesions including colitis or pancreatitis. On the 4th day of hospitalisation, serum pancreatic enzymes were extremely elevated. Amylase was increased to 683 U/L (normal range: 44-132) and lipase was increased to 1520 U/L (13-55), but he had no abdominal tenderness. Contrast-enhanced CT showed enlarged pancreatic parenchyma and magnetic resonance cholangiopancreatography showed peripancreatic fat stranding, suggesting pancreatitis. Blood culture tests and empirical antibiotic therapy with ceftriaxone indicated no active infectious diseases. We diagnosed ICI-induced pancreatitis and treated him with 0.5 mg/kg/day of prednisolone, which improved his general fatigue, anorexia, dermatitis, and pancreatitis. The potential significance of asymptomatic elevations of pancreatic enzymes has been unclear; however, this case suggested that ICI-induced pancreatitis without abdominal tenderness could be clinically significant. Clinicians should pay attention to the development of latent pancreatitis in patients receiving ICIs, even those without abdominal pain.

OBJECTIVE: Urinary free cortisol (UFC) is a reliable marker to avoid cortisol fluctuation and the effects of binding proteins. However, UFC levels are affected by fluid intake and urine volume, and the normal levels range widely. METHODS: To discover the utility of the ratio of urinary cortisol to aldosterone excretions, 246 patients in whom daily excretions of UFC and aldosterone (UAC) were measured were retrospectively analyzed. RESULTS: The UFC/UAC ratio showed significant positive and negative correlations with the levels of serum cortisol (R=0.287) and aldosterone (R=-0.762), respectively. The UFC/UAC ratio increased with aging in female patients, while it was not altered by the level of BMI in either gender. Markers for metabolic and inflammatory status, including hemoglobin A1c (R=0.327), albumin (R=-0.331), C-reactive protein (R=0.317), ferritin (R=0.473), and D-dimer (R=0.569), showed correlations with the ratio of UFC/UAC that were more significant than the correlations with the serum level of cortisol or UFC alone. Of note, the UFC/UAC ratio was shown to be an indicator for the risk of diabetes (AUC: 0.765), hypoalbuminemia (0.839), hyper-CRPemia (0.748), and thrombophilia (0.824), in which the cut-off levels of the UFC/UAC ratio were around 12. CONCLUSION: The UFC/UAC ratio is a variable for detecting metabolic and inflammatory complications related to adrenocortical dysfunction.

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) mainly affects young adults and can have a potential impact on social functioning. As this syndrome is associated with endothelial dysfunction, the heart can be damaged via ischemia due to endothelial damage. This might potentially lead to heart failure, which accounts for approximately 20% of deaths among patients with ME/CFS. While cardiac ischemia is thought be a pathophysiologically important manifestation of this syndrome, this is not yet reported. Herein, we present a case of a young female with newly diagnosed vasospastic or microvascular angina and concurrent exacerbation of ME/CFS severity. Her anginal symptoms, including exertional chest pain and transient chest discomfort, mimicked those of ME/CFS but were relieved after the administration of a calcium channel blocker. We emphasize the possibility of concurrent angina and exacerbation of ME/CFS and the importance of detecting cardiac ischemia to avoid unfavorable outcomes.

Anorexia nervosa (AN) is occasionally complicated with hypoglycemic coma, which may cause sudden death by unknown mechanisms. We present the case of a 36-year-old woman with recurrent comas and a nineteen-year history of AN. She was found in a coma with remarkable hypoglycemia (28 mg/dL). Her BMI was 11.1 kg/m2. Endocrine workup revealed extremely low serum levels of glucagon, IGF-I and insulin. Asymptomatic hypoglycemia occurred with liver injury in the refeeding process. An aberrant glucose metabolism due to liver damage might have been involved in her susceptibility to hypoglycemia. This case suggests a possible mechanism of hypoglycemic coma in AN.

Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that the BAP/ALP ratios of the patients with fever and those with inflammatory diseases were significantly lower than the ratios of other patient groups. The BAP/ALP ratios of the patients with osteoporosis and those with metabolic bone diseases were higher than those of the patients with other conditions. The BAP/ALP ratio was found to be negatively correlated with age, a cor-relation that has not been found in other ethnicities. The serum BAP/ALP ratio was inversely correlated with serum CRP levels but was positively correlated with serum albumin levels and hemoglobin concentrations. Collectively, our results suggest that the BAP/ALP ratio could be a useful predictor for important geriatric con-ditions seen in general practice.

TAFRO syndrome is a rare variant of idiopathic multicentric Castleman's disease, for which disseminated non-tuberculous mycobacteria (NTM) infection must be excluded. However, due to the slow and fastidious growth of the organisms, identification of the pathogen is often challenging. We herein describe a case of disseminated Mycobacterium genavence infection, in which manifestations of the patient were confusingly similar to those of TAFRO syndrome. A 69-year-old Japanese man presented with prolonged fever accompanying pain in his back and ribs on the right side. Systemic investigations revealed thrombocytopenia, marked elevation of alkaline phosphatase, anasarca (pleural effusion and ascites), megakaryocytosis in the bone marrow, and hepatomegaly. Magnetic resonance imaging (MRI) showed diffuse, T1-and T2-low-intensity spotted lesions on his vertebral bodies, but biopsy showed inconclusive results. The patient met the diagnostic criteria of TAFRO syndrome and was started on prednisolone, which improved his general condition shortly thereafter. Blood culture after 42 days of incubation revealed the presence of Mycobacterium; however, we considered it a contamination at that time because no organisms grew on conventional agars, and the patient was discharged. Ten weeks after the isolation of Mycobacterium, he developed persistent fever and was readmitted. This time, vertebral bone mallow biopsy demonstrated a large amount of mycobacterium, which was later successfully identified as M. genavense by sequencing analysis. Under a final diagnosis of disseminated M. genavense infection, we treated the patient with clarithromycin, rifampicin, and ethambutol. This case highlighted that disseminated NTM infection may follow a similar clinical course as that of TAFRO syndrome.

To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (≥ 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=-0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status.

Odontogenic infections, generally caused by dental caries and periodontal disease, can result in fatal illness. We herein report a 71-year-old Japanese woman with type 2 diabetes and hemodialysis who suffered from multiple dentofacial abscesses mainly caused by multidrug-resistant Streptococcus oralis. She complained of pain and swelling of her face, with an extraoral fistula from the left cheek. Following 3 surgical debridement procedures and partial mandibulectomy, in addition to 12 weeks of antimicrobial therapy, the multiple dentofacial abscesses were ameliorated. A combination of surgical and antimicrobial treatments following an early diagnosis is essential for reducing further complications.

Adrenal insufficiency patients are treated with glucocorticoid replacement therapy. However, mimicking the in vivo circadian rhythm of cortisol levels is challenging, and suboptimal replacement increases the risk of mortality from cardiovascular disease. We herein report a case of coronary spastic angina (CSA) with simultaneous low early-morning serum cortisol levels in a patient undergoing corticosteroid replacement therapy for primary adrenal insufficiency. Steroid therapy is reportedly effective for refractory angina, but underlying adrenal deficiency has never been revealed. Our case intimates the probable risk of CSA as a complication of relative adrenal insufficiency and highlights the effectiveness of dexamethasone in these patients.

BACKGROUND: The widespread administration of the Haemophilus influenzae type b vaccine has led to the predominance of non-typable H. influenzae (NTHi). However, the occurrence of invasive NTHi infection based on gynecologic diseases is still rare. CASE PRESENTATION: A 51-year-old Japanese woman with a history of adenomyoma presented with fever. Blood cultures and a vaginal discharge culture were positive with NTHi. With the high uptake in the uterus with 67Ga scintigraphy, she was diagnosed with invasive NTHi infection. In addition to antibiotic administrations, a total hysterectomy was performed. The pathological analysis found microabscess formations in adenomyosis. CONCLUSIONS: Although NTHi bacteremia consequent to a microabscess in adenomyosis is rare, this case emphasizes the need to consider the uterus as a potential source of infection in patients with underlying gynecological diseases, including an invasive NTHi infection with no known primary focus.

Objective: To differentiate patients with IgG4-related diseases (RD) from patients with other hyper IgG4 conditions who visit general medicine department.Methods: Fifty-six patients with high serum IgG4 levels (>135 mg/dL) were classified into three groups based on the final diagnosis: definite and possible IgG4-RD and others. Clinical and laboratory characteristics of the three groups of patients were retrospectively analyzed.Results: Major manifestations were renal dysfunction and general malaise, while thirst was the most frequent symptom in the definite group, in which submandibular glands and lymph nodes were likely to be affected. Biopsy of minor salivary glands was the least diagnostic for IgG4-RD despite the high frequency of biopsy. In the definite group, serum levels of IgG4 and IgG, IgG4/IgG ratio and basophil number were increased, while serum levels of CRP, IgA and complements were decreased. A negative correlation between serum levels of IgG4 and IgM was found in the definite group.Conclusion: The results indicated that in patients with renal dysfunction, malaise, thirst or weight loss, measurements of the levels of basophils, immunoglobulins and complements are helpful for diagnosing IgG4-RD. Considering distribution of affected tissues and localization of diagnostic biopsies, physical examination and laboratory workup are required for early diagnosis.

A relationship between diabetes and depression is apparent. To clarify the clinical relevance of diabetic patients' gastroesophageal symptoms to their psychological status, we retrospectively analyzed the data from a Selfrating Depression Scale (SDS) and a Frequency Scale for Symptoms of Gastroesophageal reflux disease (FSSG) among 143 type 2 diabetic patients who visited a general medicine department. Among the 45 Japanese patients enrolled, the group with relatively high SDS scores (≥ 36) showed higher (FSSG) dysmotility symptom scores versus the low-SDS (< 36) group, although the 2 groups' characteristics and laboratory data were not significantly different. Positive correlations of postprandial plasma glucose (PPG) levels with FSSG scores (R=0.321, p<0.05), particularly with reflux scores (R=0.455, p<0.01) were revealed. PPG and HbA1c levels were not correlated with SDS scores. The patients' SDS scores were significantly correlated with their FSSG scores (R=0.41, p<0.01), suggesting that depressive status is linked to GERD-related manifestations. Considering that the patients' PPG levels were correlated with GERD-related symptoms, diabetic patients' blood glucose levels are associated with depressive status. Collectively, key symptoms related to GERD and glucose level values would be helpful.

Osteoporosis increases the risk of bone fractures. It is diagnosed based on an individual's bone mineral density (BMD) or a fracture without trauma. BMD is usually measured by the dual energy X-ray absorptiometry (DXA) method. Here we investigated factors for the earliest possible prediction of decreased BMD by examining the relationships between patients' BMD values and changes in the patients' physical and laboratory values. We retrospectively reviewed the medical records of 149 patients who visited our department in 2014-2015 for a variety of reasons and underwent an area BMD examination by DXA. We analyzed the relationships between decreasing BMD and the patients' gender, age, body mass index (BMI), medical background, hemoglobin, electrolytes, and thyroid function. Thirty-nine of the patients were diagnosed with osteoporosis based on their T-scores. An adjusted analysis showed that female gender, aging, and increased serum calcium level were significantly related to decreasing femoral BMD, whereas high BMI was associated with an increase in femoral BMD. Collectively the results indicate that for the early detection of low BMD, it is important for general-practice physicians to consider conducting a BMD checkup when treating female and elderly patients with a low BMI and/or elevated serum calcium level.

Adrenocortical carcinoma (ACC) is a rare malignancy arising from adrenocortical parenchymal cells. Myxoid ACC is one of the newly identified, rare, but important histological variants of ACC, characterized by the presence of abundant extracellular Alcian Blue-positive myxoid material. Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant cancer predisposition syndrome, and the incidence of ACC in MEN1 patients has been reported to be between 1.4% and 6%. Here, we report the case of a 68-year-old Japanese woman harboring the past history of MEN1 associated with insulinoma, pituitary tumor, and hyperparathyroidism. She presented to our hospital with hypertension and hypokalemia. Imaging studies revealed a right adrenal tumor, and histological examination revealed myxoid ACC. Despite surgical resection of the tumor and mitotane therapy, the patient died 6 months after the surgery. To the best of our knowledge, this is the first reported case of the myxoid variant of ACC in a patient with MEN1. The patient's clinical course was characterized by the development of both multiple endocrine and non-endocrine neoplasm, hyperaldosteronism, and aggressive biological behavior. This case confirmed that myxoid morphology was also associated with aggressive behavior in ACC, but further studies are required to clarify the association between MEN1 and myxoid ACC.

The aim of this study was to determine the relationships between free testosterone (FT) level and parameters including laboratory data and data from questionnaires and to determine symptoms leading to the detection of late onset hypogonadism (LOH). We retrospectively reviewed medical records of patients in whom serum FT was measured in our hospital. Aging Male Symptoms (AMS) score, self-rating depression scale (SDS) and frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score were used for questionnaires. A total of 205 patients were included in the analysis (55.2 ± 15.6 years of age, mean ± SD). Among them, 119 patients (58.0%) had an FT level of less than 8.5 pg/mL, which fulfills the diagnostic criterion of LOH syndrome according to the clinical practice manual for LOH in Japan. It was revealed that FSSG score was inversely correlated to serum FT levels (r = -0.3395, p < 0.001), although SDS and AMS scales did not show significant correlations to FT levels. Our study revealed a high prevalence of LOH syndrome among patients in whom the majority complained of general symptoms. Although GERD symptoms are generally not considered to be typical symptoms of LOH, our study indicates that those symptoms might be clues for the detection of LOH.

She underwent radical hysterectomy and radiotherapy 35 years previously. She also had a surgical history of nephrostomy, nephrectomy, ileoascending anastomosis, and colostomy. As bleeding from the enterovaginal fistula was uncontrollable, ileocecal resection was performed. However, a colovesical fistula with urinary tract infection occurred 3 months later. The present case indicates that fistula formation occurs and causes various symptoms in patients who underwent postpelvic radiotherapy, particularly in those with prior surgeries in the irradiated field.

We herein report a case of central diabetes insipidus complicated with thyroid storm. A middle-aged woman who was receiving treatment for Graves' disease suddenly complained of polydipsia, polyuria and general fatigue. Laboratory tests showed hyperthyroidism, hypernatremia, hypoosmolar urine and a decreased plasma vasopressin level. The occurrence of central diabetes insipidus with hyperthyroidism was revealed on the basis of pituitary magnetic resonance imaging, a water deprivation test and a desmopressin test. The clinical co-existence of diabetes insipidus and hyperthyroidism is very rare; however, the complication should be considered when hypernatremia and/or dehydration progress in patients with Graves's disease as a common autoimmune-related etiology.

This study aimed to determine the prevalence of colorectal neoplasms and to investigate the rate of and time required for cecal intubation in patients with acromegaly. A database search performed at our institution identified 29 patients with acromegaly who underwent colonoscopy. Data regarding the endoscopic, biological, and pathological examinations performed were retrospectively reviewed from the clinical records. Subsequently, the rate of and time required for cecal intubation were investigated in 23 patients with acromegaly and compared with the corresponding data of the control group. Control subjects were selected from a 2:1 matched historical control cohort, according to baseline characteristics. The mean age of the acromegaly group (17 female and 12 male) was 60.4 ± 12.6 years. Twelve patients had adenoma (41.4%), eight patients had hyperplastic polyps (27.6%), three patients had sessile serrated adenoma/polyps (10.3%), and three patients had colon cancer (10.3%). Successful cecal intubation was achieved in all patients in both groups. The difference in the time required for successful intubation between the acromegaly group (15.7 ± 9.8 minutes) and the control group (8.7 ± 6.0 minutes) was statistically significant. Linear regression analysis revealed that increased patient age was significantly related to longer colonoscope insertion times. In conclusion, although cecal intubation during colonoscopy was successful in all participants, it required a longer time in patients with acromegaly. Our results underscore the importance of and certain technical difficulties involved in colonoscopy procedures in patients with acromegaly, especially in older patients.

A previously healthy 31-year-old man was referred to us with refractory septic shock accompanied by bilateral conjunctival congestion and erythema of his right lower limb. Nine days after admission, he had bilateral desquamation of the fingertips, and his presentation satisfied the criteria for Kawasaki disease. A serological examination was positive for Yersinia pseudotuberculosis, and he was diagnosed with Far East scarlet-like fever (FESLF). Interestingly, his 11-month-old baby boy had similar symptoms around the same time, indicating the intrafamilial transmission of the pathogen. We should consider FESLF when we encounter a familial occurrence of systemic manifestations of Kawasaki disease.

A 77-year-old female with renal dysfunction, hypercalcemia, and hypercalciuria was presented. Systemic investigations including renal biopsy showed that the patient had Fanconi syndrome secondary to renal sarcoidosis. Treatment with 25 mg per day of prednisolone was initiated and her condition improved. Complication of Fanconi syndrome in patients with sarcoidosis is extremely rare. Although the pathological mechanism is still unknown, corticosteroid therapy was effective for ameliorating proteinuria, glycosuria, hypercalciuria, and aminoaciduria.

Insulinoma is a rare, usually benign, pancreatic neuroendocrine tumor. The clinical features of an insulinoma are fasting hypoglycemia with neuroglycopenic symptoms including confusion and unusual behavior, while hypertension is usually not associated with the disease. We herein report a patient with insulinoma who manifested paroxysmal hypertension and neuroglycopenic symptoms. The possible etiology of hypertension induced by an insulinoma is catecholamine release in response to hypoglycemia, which may cause acute hypertension through activation of the sympatho-adrenal system. This case implies that sustained hyperinsulinemia due to insulinoma can be functionally linked to the induction of paroxysmal hypertension.

A 61-year-old Japanese man with IgG4-related autoimmune pancreatitis was referred to our hospital because of perspiration during food intake. Abdominal computed tomography (CT) with contrast media revealed multiple mesenteric lymphadenopathies. An open surgical abdominal biopsy and subsequent histopathological analysis revealed abnormally large lymphoid cells that were negative for CD3, CD5, and c-myc and positive for CD20 and bcl-2, leading to a diagnosis of diffuse large B-cell lymphoma. Here, we discuss the risk of malignancies, particularly malignant lymphoma in patients with IgG4-related disease. The importance of pathological analysis to reach the appropriate diagnosis in such cases should be emphasized.

KL-6 is a glycoprotein found predominantly on type II pneumocytes and alveolar macrophages, and often shows increased serum levels in patients with interstitial pneumonia. We report a case of mycobacterium avium complex (MAC) infection whose disease activity was correlated with KL-6 levels in serum. During treatment of rheumatoid arthritis (RA)-associated interstitial lung disease (ILD) with prednisolone, chest image findings improved in association with decreased KL-6 levels. Following tapering of prednisolone, chest image findings deteriorated again as levels of KL-6 increased, suggesting recurrence of RA-ILD. Bronchoscopic examination revealed active MAC infection. Treatment of MAC infection not only improved chest image findings but also decreased KL-6 levels in serum, suggesting that KL-6 was increased by active MAC infection by itself, not by recurrence of RA-ILD. To the best of our knowledge, this is the first documentation of KL-6 elevation in serum in association with active MAC infection.

A 74-year-old man who had been administered trimethoprim-sulfamethoxazole for three weeks suffered from drug-induced hypersensitivity syndrome/drug rash with eosinophilia and systemic symptoms (DIHS/DRESS). In the early stage of the clinical course, he developed renal dysfunction. A renal biopsy showed granulomatous tubulointerstitial nephritis accompanying the proliferation of human herpes virus (HHV)-6 in tubular epithelial cells. With corticosteroid therapy, the systemic rash and renal function gradually improved. The present patient is the second case of DIHS/DRESS demonstrating a possible reactivation of HHV-6 in the renal tissue. The clinical role of viral reactivation in DIHS/DRESS must be further elucidated.

We report a 42-year-old female who initially complained of sub-acute onset of right upper quadrant abdominal pain with right shoulder pain. A CT scan incidentally revealed an adrenal tumor, and a final diagnosis of pheochromocytoma was made on the basis of endocrinological examinations. Symptomatically, the pheochromocytoma in our patient mimicked a hepato-biliary disease by presenting abdominal pain accompanying right shoulder pain that was assumed to be referred pain via the right phrenic nerve. Physicians may need to consider the possibility of pheochromocytoma in patients with abdominal symptoms.

Eosinophillic glanuromatosis with polyangitis (EGPA) usually occurs in patients with a recent history (usually less than 10 years) of uncontrolled bronchial asthma. Here we describe a case of EGPA that occurred in a 68-year-old female who had well-controlled bronchial asthma for 17 years. A leukotriene receptor antagonist that had been prescribed one week before onset might have triggered the disease. Our case shows that there is a wide spectrum of clinical characteristics of EGPA, making diagnosis difficult in a primary care setting.

A 67-year-old man with a persistent high fever was diagnosed to have an infective aneurysm in his left internal iliac artery. A blood culture detected a gram-negative spiral rod that was first identified as Campylobacter fetus subsp. venerealis based on a matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) analysis. However, the strain was finally confirmed to be Campylobacter fetus subsp. fetus based on a genetic analysis. The infection was successfully treated with emergency resection of the aneurysm, followed by 4 weeks of antibiotic therapy. Involvement of the peripheral artery is uncommon in cases of C. fetus-infective aneurysm. To figure out the epidemiology and pathogenicity of C. fetus infection, the accurate identification of the responsible organisms is essential.

An 81-year-old Japanese male with primary Sjögren syndrome (pSS) developed a low-grade fever and productive cough which were refractory to antibiotic therapy. Based on the high level of eosinophils observed in his bronchial alveolar lavage, he was diagnosed with chronic eosinophilic pneumonia (CEP) and successfully treated by oral prednisolone. Interstitial lung diseases associated with pSS (pSS-ILDs) usually present as nonspecific interstitial pneumonia or usual interstitial pneumonia; therefore, the present case is extremely unique in that the patient's condition was complicated with CEP. A diagnosis of advanced gallbladder cancer was made in the patient's clinical course, suggesting the advisability of a whole-body workup in cases of pSS, especially in elderly patients.

A 34-year-old man with 22q11.2 deletion syndrome (DiGeorge syndrome) concurrently suffered from myopathy and eosinophilic pneumonia shortly after receiving daptomycin (DAP) for right-sided infective endocarditis. The simultaneous occurrence of these phenomena in relation to DAP therapy has not been previously well described. An allergic reaction was suspected as a possible etiology of these DAP-related complications. This case highlights the need for close observation in order to detect both musculoskeletal and respiratory disorders from the start of DAP therapy. Physicians should pay more attention to this new drug, which is expected to be frequently used in various clinical settings.

We report a case of nephrostomy-associated urinary tract infection caused by Elizabethkingia meningoseptica that occurred in a patient with retroperitoneal fibrosis. Though conventional identification methods failed to detect the causative organism, it was identified on the basis of the complete sequencing of 16S rRNA. Four weeks of levofloxacin and minocycline administration successfully eradicated the infection. E. meningoseptica rarely causes urinary tract infections, and we believe that this is the first such case in which the isolate was genetically confirmed. The accurate identification of the organism is necessary for the provision of appropriate treatment and to obtain a better understanding of its epidemiology and pathogenicity.

A 69-year-old man with diabetes mellitus was diagnosed with a prostate abscess. Although the pathogen was fluoroquinolone-resistant Escherichia coli and the oral administration of trimethoprim-sulfamethoxazole was initiated, the infection recurred after three months. The antibiotic therapy was subsequently changed to intravenous fosfomycin, and the patient's condition promptly improved. Four weeks of fosfomycin therapy was successfully continued without any adverse events. In the era of antibiotic resistance, revival of forgotten drugs is an important issue for clinicians. Fosfomycin can be applied as an alternative option for prostate infections, considering the remaining susceptibility of multidrug-resistant pathogens to fosfomycin and the good pharmacokinetics of this drug in prostatic tissue.

症例は30歳代ネパール人男性で、下痢と嘔気を主訴とした。ハンセン病(LL型)と新型コロナウイルス感染症の既往があり、らい反応に対して長期間のステロイド製剤内服による免疫抑制療法を行っていた。各種検査所見より、糞線虫の過剰感染状態による播種性糞線虫症と診断した。栄養状態は不良で、寄生虫の消化管内過剰増殖に伴う腸管浮腫を認め、イベルメクチンは吸収不良で血中濃度が不十分であった。多臓器不全を併発したため集学的治療を行ったが第36病日に死亡した。日本では糞線虫症は稀であるが、インバウンドの増加に伴い播種性糞線虫症のリスクが増加する可能性があり、ステロイドの長期内服などで免疫抑制状態の可能性がある場合は寄生虫スクリーニングを行う必要があると考えられた。

40歳代女性。当院受診の4年前より胸痛を主訴に3度の入院歴がある。いずれも胸膜炎の診断で抗菌薬にて加療され、軽快していた。今回、発熱および胸痛を主訴に当院受診し、胸部X線検査にて浸潤影が認められた。経口避妊薬の内服と胸膜炎を繰り返していた既往から造影CT検査を施行したところ、肺動脈血栓と下肢深部静脈血栓を認めた。入院後、抗菌薬とヘパリン、ワルファリンにて治療を行った。退院時CT検査にて、肺炎像は消退傾向であり、血栓は全て消失していた。肺動脈血栓症は肺炎と類似した所見を示すことがあるため、経過や症状、リスク因子などから疑われる場合には、造影CT検査などを用いて積極的に検索を行うことが重要であると考えられた。(著者抄録)
