RESUMO

The prognosis of patients with connective tissue disease (CTD) has improved significantly in recent years, but interstitial lung disease (ILD) associated with connective tissue disease (CTD-ILD) remains a refractory condition, which is a leading cause of mortality. Because it is an important prognostic factor, many observational and interventional studies have been conducted to date. However, CTD is a heterogeneous group of conditions, which makes the clinical course, treatment responses, and prognosis of CTD-ILD extremely diverse. To summarize the current understanding and unsolved questions, the Japanese Respiratory Society and the Japan College of Rheumatology collaborated to publish the world's first guide focusing on CTD-ILD, based on the evidence and expert consensus of pulmonologists and rheumatologists, along with radiologists, pathologists, and dermatologists. The task force members proposed a total of 27 items, including 7 for general topics, 9 for disease-specific topics, 3 for complications, 4 for pharmacologic treatments, and 4 for non-pharmacologic therapies, with teams of 2-4 authors and reviewers for each item to prepare a consensus statement based on a systematic literature review. Subsequently, public opinions were collected from members of both societies, and a critical review was conducted by external reviewers. Finally, the task force finalized the guide upon discussion and consensus generation. This guide is expected to contribute to the standardization of CTD-ILD medical care and is also useful as a tool for promoting future research by clarifying unresolved issues.

RESUMO

OBJECTIVES: The aim of this study was to compare the clinical effectiveness of tofacitinib and abatacept and clarify the impact of the HLA-DRB1 shared epitope (SE) on responses to these treatments in patients with rheumatoid arthritis (RA). METHODS: After adjustments by propensity score matching, 70 out of 161 patients receiving tofacitinib and 70 out of 131 receiving abatacept were extracted. The clinical effectiveness of both drugs over 24 weeks and the impact of the copy numbers of SE on effectiveness outcomes were investigated. RESULTS: The percentage of patients in remission in the 28-joint count disease activity score using the erythrocyte sedimentation rate (DAS28-ESR) did not significantly differ between patients receiving tofacitinib and abatacept at week 24 (32% vs 37%, p = 0.359). The mean change at week 4 in DAS28-ESR from baseline was significantly greater in patients receiving tofacitinib than in those receiving abatacept (- 1.516 vs - 0.827, p = 0.0003). The percentage of patients in remission at week 4 was 30% with tofacitinib and 15% with abatacept (p = 0.016). When patients were stratified by the copy numbers of SE alleles, differences in these numbers did not affect DAS28-ESR scores of patients receiving tofacitinib. However, among patients receiving abatacept, DAS28-ESR scores were significantly lower in patients carrying 2 copies of SE alleles than in those carrying 0 copies at each time point throughout the 24-week period. Furthermore, the percentage of patients in remission with DAS28-ESR at week 24 was not affected by the copy numbers of SE alleles in patients receiving tofacitinib (p = 0.947), whereas it significantly increased as the copy numbers became higher in patients receiving abatacept (p = 0.00309). Multivariable logistic regression analyses showed a correlation between the presence of SE and DAS28-ESR remission in patients receiving abatacept (OR = 25.881, 95% CI = 3.140-213.351, p = 0.0025), but not in those receiving tofacitinib (OR = 1.473, 95% CI = 0.291-7.446, p = 0.639). CONCLUSIONS: Although the clinical effectiveness of tofacitinib and abatacept was similar at week 24, tofacitinib was superior to abatacept for changes from baseline in DAS28-ESR and the achievement of remission at week 4. SE positivity was associated with the achievement of DAS28-ESR remission by week 24 in patients receiving abatacept, but not in those receiving tofacitinib.

RESUMO

This study aimed to evaluate the prevalence of, and the factors associated with, frailty in Japanese patients with rheumatoid arthritis (RA). Patients with RA enrolled in the Institute of Rheumatology Rheumatoid Arthritis (IORRA) cohort completed self-administered questionnaires, which included the 5-item frailty screening index. Patients were classified as frail, prefrail, or robust based on the 5 components of the frailty screening index. Logistic regression analyses were used to evaluate associations between clinical variables and frailty. Among 3,290 Japanese patients with RA (86.7% female, mean age 62.4 years) who participated this frailty study, 549 (16.7%) patients were categorized as frailty, 2,063 (62.7%) as prefrailty, and 678 (20.6%) as robust. In multivariable models, body mass index (BMI) ≥ 25 kg/m2 (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.41 to 2.47), BMI < 18.5 kg/m2 (OR 1.31, 95% CI 1.00 to 1.71), disease activity scores in 28 joints (DAS28) (OR 1.32, 95% CI 1.18 to 1.47), Japanese version of Health Assessment Questionnaire disability index (J-HAQ) (OR 1.26, 95% CI 1.04 to 1.52), the European Quality of Life-5 Dimensions (EQ-5D) (OR 0.80, 95% CI 0.74 to 0.85), non-steroidal anti-inflammatory drug (NSAID) use (OR 1.59, 95% CI 1.23 to 1.98), and methotrexate (MTX) use (OR 0.75, 95% CI 0.60 to 0.94) were significantly (P < 0.05) associated with frailty. BMI (both overweight and underweight), DAS28, J-HAQ, EQ-5D, NSAID use, and MTX nonuse appear to be associated with frailty in Japanese patients with RA. Key Points • This is the largest study showing the prevalence and the associated factors of frailty in patients with RA. • Maintaining normal BMI appears to be important for preventing frailty in patients with RA. • We confirmed the significant associations of frailty with high disease activity, high degree of disability, and poor health related QOL in Japanese patients with RA. • NSAID use and MTX nonuse were associated with the frailty in Japanese patients with RA, which could be explained by patients' background.

RESUMO

In this study, we assess the association between the occurrence of new fractures and vitamin D deficiency in Japanese patients with rheumatoid arthritis using our large IORRA cohort. The results suggest that vitamin D deficiency is a significant risk factor for new fractures in Japanese female patients over the age of 50 years with rheumatoid arthritis. PURPOSE: Both rheumatoid arthritis (RA) and menopause are known risk factors for the onset of osteoporosis. The occurrence of new clinical fractures in patients with RA can significantly lower quality of life. The purpose of this study was to investigate whether vitamin D deficiency in Japanese women with RA could be a risk factor for new fractures. METHODS: Between 2011 and 2017, a total of 2567 female patients with RA over the age of 50 years (mean age, 65.9 years) were enrolled in a prospective observational study. Self-reported occurrences of new fractures were verified using patient medical records. Vitamin D deficiency was defined as serum 25(OH)D levels < 20 ng/mL. Cox proportional hazards models were used to analyze the independent contributions of various risk factors to the occurrence of a new fracture. RESULTS: New clinical fractures were sustained by 205 patients in the included cases. Among them, new osteoporotic fractures were sustained by 139 patients (63 vertebral fractures and 76 non-vertebral fractures). Among all patients, the mean (SD) serum 25(OH)D level was 16.9 (5.89) ng/mL and the prevalence of vitamin D deficiency was 72.6%. A Cox proportional hazards model revealed that vitamin D deficiency was significantly associated with all new clinical fractures (hazard ratio, 1.44 [95% confidence interval 1.02‒2.05]; p = 0.0365) and all new osteoporotic fractures (hazard ratio, 1.75 [95% confidence interval 1.14‒2.69]; p = 0.0109). CONCLUSION: Vitamin D deficiency is a risk factor for new fractures in Japanese female patients over the age of 50 years with RA. Screening these patients for serum 25(OH)D could potentially be seminal to reducing their risk of fractures.

RESUMO

OBJECTIVES: Evidence for the utility of medications in settings lacking randomised trial data can come from studies of treatment persistence. We examined patterns of medication use in systemic lupus erythematosus (SLE) using data from a large multicentre longitudinal cohort. METHODS: Prospectively collected data from the Asia Pacific Lupus Collaboration cohort including disease activity (SLEDAI-2K) and medication details, captured at every visit from 2013-18, were used. Medications were categorised as glucocorticoids (GC), anti-malarials (AM), and immunosuppressants (IS). Cox regression analyses were performed to determine the time-to-discontinuation of medications, stratified by SLE disease activity. RESULTS: Data from 19,804 visits of 2,860 patients were analysed. Eight medication categories were observed: no treatment; GC, AM or IS only; GC+AM; GC+IS; AM+IS and GC+AM+IS (triple therapy). Triple therapy was the most frequent pattern (31.4% of visits); single agents were used in 21% of visits and biologicals in only 3%. Time-to-discontinuation analysis indicated that medication persistence varied widely, with the highest treatment persistence for AM and lowest for IS. Patients with time-adjusted mean SLEDAI-2K≥10 had lower discontinuation of GC and higher discontinuation of IS. CONCLUSION: Most patients received combination treatment. GC persistence was high, while IS persistence was low. Patients with high disease activity received more medication combinations but had reduced IS persistence, consistent with limited utility. These data confirm unmet need for improved SLE treatments.

RESUMO

INTRODUCTION: Upadacitinib is a Janus kinase inhibitor with demonstrated efficacy in patients with rheumatoid arthritis (RA). OBJECTIVE: The aim of this study was to assess the long-term safety of upadacitinib in patients with active RA from Japan compared with global clinical trial populations. METHODS: Pooled data in patients enrolled from Japan (the 'Japanese population'; SELECT-SUNRISE, SELECT-EARLY, and SELECT-MONOTHERAPY) were compared with that from global (Japan and ex-Japan) upadacitinib clinical trial populations and summarized descriptively. RESULTS: The Japanese population (mean age 57.0 years; mean RA duration 6.1 years) received upadacitinib 7.5 mg (n = 121), 15 mg (n = 126), and 30 mg (n = 124) once daily, while the global population (mean age 54.8 years; mean RA duration 9.1 years) received upadacitinib 6 mg twice daily/15 mg once daily (n = 2883) and 12 mg twice daily/30 mg once daily (n = 1375). Most patients were female (79.3%). The exposure-adjusted incidence rates (EAIRs) of serious adverse events in the Japanese population were 11.5, 12.2, and 21.2 per 100 patient-years (PY) with upadacitinib 7.5, 15, and 30 mg, respectively. Herpes zoster rates were higher in the Japanese population (7.8, 12.4, and 16.7 per 100 PY with 7.5, 15, and 30 mg, respectively) versus global populations (3.7 and 7.0 per 100 PY with 15 and 30 mg, respectively). Prior herpes zoster was a significant risk factor for herpes zoster. CONCLUSIONS: The safety profile of upadacitinib was generally similar between Japanese and global RA populations, except for higher EAIRs for serious adverse events and infections, including herpes zoster, in the Japanese population.

RESUMO

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.

RESUMO

PURPOSE: Adult-onset Still's disease (AOSD) is an inflammatory condition commonly complicated by mild liver dysfunction. However, severe liver failure is rarely reported. We report three cases of severe acute hepatic failure (ALF) associated with AOSD. We encountered three cases of acute liver failure (ALF) with encephalopathy. RESULTS: Case 1 was a 75-year-old female, who was started on a steroid (prednisolone, PSL) to treat AOSD; this was gradually tapered. Two months later, severe ALF developed. She died despite an increase in the PSL dose and artificial liver support. Case 2 was a 26-year-old-female taking PSL 30 mg/day to treat subacute thyroiditis. PSL was tapered, and she received methyl PSL pulse therapy and artificial liver support, but this did not cure the ALF. Liver transplantation (LT) was performed 25 days later. Three years later, the same symptoms were observed and we diagnosed AOSD. Case 3 was a 56-year-old-female who met the AOSD criteria. PSL 50 mg/day was started and then tapered. Methyl PSL pulse therapy was prescribed to treat hemophagocytic syndrome, but she required LT on hospital day 13. CONCLUSION: In AOSD cases, ALF is rarely complicated; urgent LT should be considered only for patients with AOSD-related severe ALF.

RESUMO

AIM: Calcinosis is often observed in systemic sclerosis (SSc), but its pathogenesis remains unclear. The aim of the present study was to explore the association of clinical features with calcinosis in patients with SSc. METHODS: A retrospective cohort study was performed analyzing 416 SSc patients from our SSc database. We examined the clinical features with relation to calcinosis and SSc. RESULTS: Calcinosis was observed in 24.0% of patients with SSc. The group with calcinosis comprised more female patients (P < 0.05) and diffuse cutaneous types (P < 0.001) than the group without calcinosis. Complications of Raynaud's phenomenon (P < 0.05), nail fold bleeding (NFB) (P < 0.001), peripheral bone resorption (P < 0.001), myositis (P < 0.001), and pulmonary hypertension (P < 0.05) were more frequently observed in patients with calcinosis compared with those without calcinosis. The group with calcinosis had a higher modified Rodnan total skin-thickness score (mRSS) than the group without calcinosis (P < 0.001). The factors that affected calcinosis in multivariable analysis were peripheral bone resorption (partial correlation coefficient 0.46, 34%), anti-Scl-70 antibody (partial correlation coefficient 0.29, 20%), diffuse type (partial correlation coefficient 0.34, 16%) and NFB (partial correlation coefficient 0.23, 11.2%). CONCLUSIONS: Calcinosis in SSc is associated with Raynaud's phenomenon, NFB, and pulmonary hypertension, so peripheral circulatory insufficiency seems to be one of the causes of calcinosis. Furthermore, as it is related to mRSS and the diffuse cutaneous type, common factors related to skin fibrosis are considered to be involved.

RESUMO

OBJECTIVES: To characterize the treatments for rheumatoid arthritis (RA) among institution types and prefectures in Japan. METHODS: Using the National Database of Health Insurance Claims and Specific Health Checkups of Japan in the 2017 fiscal year, we investigated disease-modifying antirheumatic drug (DMARD) and oral corticosteroid prescription trends across 825 thousand RA patients. These data were compared between specialized and non-specialized institutions and by prefecture. RA specialized institutions (SIs) were defined as either institutions registered in the rheumatology training program at the Japan College of Rheumatology or institutions where board-certified rheumatologists were employed. RESULTS: The overall percentage of patients who never visited an SI was 31.8% and increased with age (16-29 years old = 15.6%; ≥80 years = 42.8%). In twelve prefectures (25.5%), the proportions of patients who never visited an SI were at least 10% higher than the overall average. The proportions of patients who only visited SIs and were prescribed methotrexate and biological DMARDs were ranged from 51.9-72.9% and 19.5-33.2%, respectively. However, those of patients who had never visited an SI and were prescribed those medications were 44.0-71.6% and 7.2-28.0%, respectively. CONCLUSIONS: This is the first study evaluating the trends in RA treatments by prefecture and institution specialty by using the NDB Japan. Opportunities of patients with RA for visiting SI was unevenly distributed in Japan, affecting some aspects of treatment provided.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: We previously identified tissue inhibitor of metalloproteinase 1 (TIMP-1) as a biomarker of disease activity that distinguished mildly or highly active antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) from remission 6 months after the initiation of remission-induction therapy. In the present study, we investigated whether TIMP-1 is clinically useful as a predictor of relapse and sustained remission in AAV patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) during maintenance therapy. METHODS: The relationship between serum TIMP-1 levels and clinical outcomes in AAV patients receiving maintenance therapy was assessed using the follow-up data of a Japanese large-cohort study (the RemIT-JAV-RPGN study) and data collected from AAV patients on maintenance therapy in our hospital (the MAAV-EU study). RESULTS: In the RemIT-JAV RPGN study, serum levels of TIMP-1 were significantly higher in mildly active AAV patients with MPA and GPA 6 months after the initiation of remission-induction therapy than in patients in remission. Regarding maintenance therapy, elevated levels of TIMP-1 in patients in remission were associated with relapse and/or difficulty reducing the glucocorticoid dosage after 6 to 12 months. In the MAAV-EU study, serum levels of TIMP-1 were elevated in relapsed patients 6 months before relapse, earlier than the increase in serum levels of CRP. Analyses of both studies revealed that approximately 30% of patients in remission with a serum TIMP-1 level ≥ 150 ng/mL relapsed after 6 to 12 months, while the majority of patients with a TIMP-1 level < 150 ng/mL sustained remission for at least 12 months. CONCLUSION: We herein demonstrated that TIMP-1 is more useful as a predictive biomarker of sustained remission than as a predictor of relapse in maintenance therapy for AAV. TIMP-1 levels < 150 ng/mL are important for the long-term maintenance of remission and may be an indicator for the tapering or cessation of treatment.

RESUMO

BACKGROUND: Clinical phenotypes and outcomes in juvenile dermatomyositis (JDM) have been defined by various myositis-specific autoantibodies (MSAs). One of the recently described MSAs associated with DM is targeted against the small ubiquitin-like modifier 1 activating enzyme (SAE). We report an anti-SAE autoantibody-positive JDM patient complicated with interstitial lung disease (ILD). CASE PRESENTATION: An 8-year-8-month-old Japanese girl presented with bilateral eyelid edema and facial erythema. At 8 years 4 months, she had dry cough and papules with erythema on the dorsal side of the interphalangeal joints of both hands. Her facial erythema gradually worsened and did not improve with topical steroids. At the first visit to our department at 8 years 8 months of age, she had a typical heliotrope rash and Gottron's papules, with no fever or weight loss, and a chest computed tomography scan showed ground-glass opacity under visceral pleura. There was no clinical evidence of myositis, muscle weakness, myalgia, or muscle magnetic resonance imaging (MRI) findings. She had mild dry cough, without any signs of respiratory distress. Laboratory tests showed no elevated inflammatory markers. She had a normal serum creatine kinase level with a slightly elevated aldolase level, and serum anti-SAE autoantibody was detected by immunoprecipitation-western blotting. She was diagnosed with juvenile amyopathic DM complicated by ILD and received two courses of methylprednisolone pulse therapy followed by oral corticosteroid and cyclosporin A. We gradually reduced the corticosteroid dose as her skin rash improved after treatment initiation. There was no progression of muscle symptoms, dysphagia, or disease flare during a 24-month follow-up period. CONCLUSIONS: We report a patient with anti-SAE autoantibody-positive JDM complicated by interstitial pneumonia. This patient had no progression of muscle symptoms and dysphagia during a 24-month follow-up period, which differs from previous reports in adult patients with MSAs. There have been no previous reports of pediatric patients with SAE presenting with ILD. However, ILD seen in this case was not rapidly progressive and did not require cytotoxic agents. To prevent overtreatment, appropriate treatment choices are required considering the type of ILD.

RESUMO

BACKGROUND: Systemic sclerosis (SSc; scleroderma) is an autoimmune connective tissue disease that affects the skin and subcutaneous tissue, in addition to the internal organs of the whole body. Onset in childhood is uncommon; however, both patients with childhood-onset and adult-onset SSc are positive for anti-nuclear antibodies (ANAs).Detection of SSc-related anti-nuclear antibodies is often useful for predicting clinical features, disease course, and outcomes. CASE PRESENTATION: A 5-year-old Japanese female manifested gradually progressive abnormal gait disturbance, regression of motor development, Raynaud's phenomenon, and the shiny appearance of the skin of the face and extremities at age 2. On admission, she presented a mask-like appearance, loss of wrinkles and skin folds, puffy fingers, moderate diffuse scleroderma (18/51 of the modified Rodnan total skin thickness score), and contracture in the ankle and proximal interphalangeal joints. Grossly visible capillary hemorrhage on nail fold and severe abnormal capillaroscopy findings including bleeding, giant loop and disappearance of capillaryconsistent with the late phase in SSc. A skin biopsy showed fibrous thickening of the dermis, entrapment of an eccrine sweat glands, and thickened fiber. Chest high-resolution computed tomographic scanning demonstrated patchy areas of ill-defined air-space opacity and consolidation predominantly involving the posterior basilar aspects of the lower lobes presenting withinterstitial lung disease. Positive ANA (1:160 nucleolar and homogeneous nuclear staining by indirect fluorescent antibody technique) and double-seropositive for anti-Th/To and anti-PM-Scl antibodies were identified. She was diagnosed with diffuse cutaneous SSc based on the Pediatric Rheumatology European Society/American College of Rheumatology/European League Against Rheumatism Provisional Classification Criteria for Juvenile Systemic Sclerosis and was successfully treated with immunosuppressive agents, including methylprednisolone pulses and intravenous cyclophosphamide. CONCLUSIONS: We experienced the first case of juvenile SSc with anti-PM-Scl and anti-Th/To antibodies. ILD was identified as a typical feature of patients with these autoantibodies; however, diffuse cutaneous SSc and joint contraction were uncharacteristically associated. The case showed unexpected clinical findings though the existence of SSc-related autoantibodies aids in determining possible organ involvement and to estimate the children's outcome.

RESUMO

OBJECTIVE: The prevalence and associations of leucopenia in SLE remain incompletely understood. We evaluated associations of disease activity and medication use with leucopenia (lymphopenia and neutropenia) in a multinational, prospectively followed SLE cohort. METHODS: Data from the Asia Pacific Lupus Collaboration cohort, in which disease activity and medications were prospectively captured from 2013-18, were used. Predictors of lymphopenia (lymphocyte count < 0.8 x 109/l) and neutropenia (neutrophil count < 1.5 x 109/l) were examined using multiple failure, time-dependent survival analyses. RESULTS: Data from 2,330 patients and 18 287 visits were analysed. One thousand three hundred twelve patients (43.7%) had at least one episode of leucopenia. 867 patients (37.2%) had lymphopenia, observed in 3,065 (16.8%) visits, and 292 (12.5%) patients had neutropenia, in 622 (3.4%) visits. After multivariable analyses, lymphopenia was associated with overall disease activity, ESR, serology, prednisolone, azathioprine, methotrexate, tacrolimus, cyclophosphamide and rituximab use. Methotrexate and ciclosporin were negatively associated with neutropenia. Lupus low disease activity state (LLDAS) was negatively associated with both lymphopenia and neutropenia. CONCLUSION: Both lymphopenia and neutropenia were common in SLE patients but were differentially associated with disease and treatment variables. Lymphopenia and neutropenia should be considered independently in studies in SLE.

RESUMO

OBJECTIVE: To describe the clinicopathological characteristics of lymphoproliferative disorders (LPDs) in patients with rheumatoid arthritis (RA). METHODS: In this multicenter case series, we retrospectively reviewed the medical records of RA patients who were newly diagnosed as having LPDs with or without biopsy confirmation between 2000 and 2017 in eight hospitals in Japan. RESULTS: We included 232 patients with LPDs. The median age was 67 years (interquartile range [IQR], 60-73 years), and 77.1% were female. At the time of LPD diagnosis, 94.8% and 62.6% of the patients were methotrexate users and in remission or had low RA disease activity, respectively; lymphadenopathy and extranodal involvement were present in 77.1% and 51.9%, respectively. Major extranodal sites were the lungs and oral/oropharyngeal mucosa. The most common LPD pathological subtype was diffuse large B-cell lymphoma (40.5%), followed by classic Hodgkin lymphoma (10.8%), Epstein-Barr virus-positive mucocutaneous ulcer (7.7%), and reactive lymphoid hyperplasia (6.2%). The clinical and laboratory characteristics varied across the pathological subtypes. CONCLUSION: LPD occurred mainly in methotrexate users, while RA disease activity did not seem to be associated with LPD development. Although the clinical manifestations vary among pathological subtypes, manifestations of LPD in patients with RA can include lymphadenopathy, extranodal mass, and mucocutaneous ulcer.

RESUMO

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.

RESUMO

A novel patient cluster in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) may be identified in Japan. We performed multiple correspondence and cluster analysis regarding 427 clinically diagnosed AAV patients excluding eosinophilic granulomatosis with polyangiitis. Model 1 included the ANCA phenotype, items of the Birmingham Vasculitis Activity Score, and interstitial lung disease; model 2 included serum creatinine (s-Cr) and C-reactive protein (CRP) levels with model 1 components. In seven clusters determined in model 1, the ANCA-negative (n = 8) and proteinase 3-ANCA-positive (n = 41) groups emerged as two distinct clusters. The other five myeloperoxidase-ANCA-positive clusters were characterized by ear, nose, and throat (ENT) (n = 47); cutaneous (n = 36); renal (n = 256), non-renal (n = 33); and both ENT and cutaneous symptoms (n = 6). Four clusters in model 2 were characterized by myeloperoxidase-ANCA negativity (n = 42), without s-Cr elevation (< 1.3 mg/dL) (n = 157), s-Cr elevation (≥ 1.3 mg/dL) with high CRP (> 10 mg/dL) (n = 71), or s-Cr elevation (≥ 1.3 mg/dL) without high CRP (≤ 10 mg/dL) (n = 157). Overall, renal, and relapse-free survival rates were significantly different across the four clusters in model 2. ENT, cutaneous, and renal symptoms may be useful in characterization of Japanese AAV patients with myeloperoxidase-ANCA. The combination of s-Cr and CRP levels may be predictive of prognosis.

RESUMO

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.
