ABSTRACT
We aimed to clarify the long-term safety and efficacy of rituximab (RTX) as a remission induction therapy following severe relapse in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). We retrospectively collected the data of patients with severely relapsed AAV from a Japanese multicentre cohort. The primary exposure was RTX use; the primary outcome was complete remission (CR) proportions at week 24. Baseline characteristics were compared between the RTX and non-RTX groups. We performed multivariate logistic regression analysis and one-to-one propensity score matching analysis as a sensitivity analysis. Totally, 100 patients were enrolled: 52 in the RTX group and 48 in the non-RTX group. Baseline characteristics were comparable between the two groups, except for age, AAV subtype and ANCA serotype. The median age was 71 vs. 75 years, and the PR3-ANCA positivity rate was 44.2% vs. 18.8% in the RTX and non-RTX groups, respectively. No significant difference was observed in CR proportions at week 24 between the two groups (79.2% vs. 68.1%, p = 0.321), with an adjusted odds ratio of 1.27 (95% confidence interval [CI] 0.47-3.51). At week 48, CR proportions were significantly higher in the RTX group (91.7% vs. 64.9%, p = 0.005), with an adjusted odds ratio of 2.95 (95% CI 0.97-9.91). Serious infection rates were lower in the RTX group than in the non-RTX group, with no statistically significant difference. RTX was not superior to conventional immunosuppressive therapies at week 24 but showed significantly favourable results at week 48 for severely relapsed AAV.
ABSTRACT
BACKGROUND: Clinical guidance on the identification and management of connective tissue disease-associated interstitial lung disease (CTD-ILD) is needed for optimal clinical practice. We aimed to develop clinical algorithms for identifying and managing three common CTD-ILDs: those associated with systemic sclerosis (SSc-ILD), rheumatoid arthritis (RA-ILD), and polymyositis/dermatomyositis (PM/DM-ILD). RESEARCH DESIGN AND METHODS: Meetings were held October-November 2023 to create consensus-based algorithms for identifying and managing SSc-ILD, RA-ILD, and PM/DM-ILD in clinical practice, based on expert consensus statements for identification and management of CTD-ILD previously derived from a Delphi process. RESULTS: We developed clinical algorithms for SSc-ILD, RA-ILD, and PM/DM-ILD that highlight both commonalities and differences in the identification and management of these CTD-ILDs. Importantly, ILD should be suspected in patients with SSc, RA, or PM/DM who have respiratory symptoms. Chest high-resolution computed tomography has utility for screening, diagnosis and assessment of severity. Furthermore, regular follow-up and multidisciplinary management are important. Disease-specific considerations include unique risk factors such as anti-topoisomerase I antibodies in SSc-ILD, high-titer cyclic citrullinated peptide antibodies in RA, anti-aminoacyl tRNA synthetase antibodies in PM/DM, and anti-melanoma differentiation-associated gene 5 antibody in DM. CONCLUSIONS: These algorithms may help physicians to identify and manage patients with SSc-ILD, RA-ILD, or PM/DM-ILD.

OBJECTIVES: This study aimed at identifying challenges nurses face in caring for patients with juvenile idiopathic arthritis (JIA) in Japan. METHODS: Nurses certified by the Japan Rheumatism Foundation were asked to describe their challenges with caring for JIA patients. Data was analyzed using qualitative content analysis. RESULTS: Responses were collected from 89 participants. 58 issues were identified from 40 participants with experience caring for JIA patients. Sixteen categories emerged, grouped into five challenges: communication, understanding, expertise, system, and collaboration. Care for JIA patients included different challenges from adult patients with rheumatoid arthritis, such as complicated patient-parent relationships, inadequate patient independence and insufficient patient information. Moreover, 76 issues from 49 participants with no experience were identified. Seven categories emerged, grouped into two challenges: expertise and opportunity. Issues included in expertise between both groups were similar. Even with no experience caring for JIA patients, nurses recognized the importance of acquiring knowledge. CONCLUSION: This is the first study in Japan regarding the difficulties nurses face in caring for JIA patients. Multidisciplinary team care and a comprehensive understanding of the patient journey, including relationships with guardians, acquaintances, and healthcare providers, is crucial to improve treatment outcome and overall patient quality of life.
ABSTRACT
Objectives We investigated the current perspectives regarding the management of late-onset rheumatoid arthritis (LORA) among rheumatologists in clinical practice. Methods This study was performed in October 2021, and included 65 rheumatologists certified by the Japan College of Rheumatology, who were administered questionnaires (including multiple choice and descriptive formulae) regarding the management of LORA. We aggregated and analyzed the responses. Results All 65 rheumatologists responded to the survey; 47 (72%) answered that >50% of newly diagnosed patients were aged ≥65 years, 42 (65%) answered that achievement of remission or low disease activity was the treatment goal, and 40 (62%) considered patient safety to be the highest priority. Most rheumatologists are concerned about the management of conditions other than RA, such as comorbidities, financial constraints, and life circumstances that interfere with standard or recommended treatment implementation. Conclusion This preliminary survey highlighted various rheumatologists' perspectives regarding the management of LORA.
ABSTRACT
OBJECTIVES: To update evidence on the efficacy and safety of disease-modifying antirheumatic drugs (DMARDs) and provide information to the taskforce for the 2024 update of the Japan College of Rheumatology (JCR) clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA). METHODS: We searched various databases for randomised controlled trials on RA published until June 2022, with no language restriction. For each of the 15 clinical questions, 2 independent reviewers screened the articles, evaluated the core outcomes, and performed meta-analyses. RESULTS: Subcutaneous injection of methotrexate (MTX) showed similar efficacy to oral MTX in MTX-naïve RA patients. Ozoralizumab combined with MTX improved drug efficacy compared to the placebo in RA patients with inadequate response (IR) to csDMARD. Rituximab with and without concomitant csDMARDs showed similar efficacy to other bDMARDs in bDMARD-IR RA patients. Combined Janus kinase inhibitors and MTX achieved similar clinical responses and equal safety during a 4-year period compared to tumour necrosis factor inhibitors in MTX-IR RA patients. Biosimilars showed efficacy equivalent to that of the original bDMARDs in csDMARD-IR and bDMARD-IR RA patients. CONCLUSION: This systematic review provides latest evidence for the 2024 update of the JCR CPG for RA management.
ABSTRACT
The Epstein-Barr virus (EBV) is associated with various lymphoproliferative disorders (LPD). Additionally, EBV infection has correlated with diverse autoimmune diseases. However, the association between EBV and systemic small vessel vasculitis (SVV) remains controversial. Here, we report a case of SVV with pauci-immune glomerulonephritis accompanied by an EBV-positive polymorphic B-cell LPD, not otherwise specified. The intricate distinction between EBV-positive B-cell LPD and SVV was difficult, as both diseases demonstrated similar clinical presentations. Lymph node and kidney biopsies facilitated the accurate diagnosis of these two conditions. The administration of high-dose prednisolone, combined with rituximab, proved efficacious, with no instances of relapse over the subsequent 2-year period. This case indicates an association between EBV-positive B-cell LPD and SVV. The diligent execution of biopsies is a crucial diagnostic and interpretive strategy, generating precise comprehension of this condition and guiding its appropriate therapeutic management.
ABSTRACT
OBJECTIVES: To evaluate the effectiveness and safety of two different intravenous methylprednisolone (IVMP) pulse doses in patients with severe microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). METHODS: We emulated a target trial using observational data from the nationwide registry in Japan. Patients with severe glomerulonephritis or diffuse alveolar haemorrhage were selected and pseudo-randomised into three groups using propensity score-based overlap weighting as follows: non-IVMP, IVMP 0.5 g/day, and IVMP 1.0 g/day. The primary outcome was all-cause death, and the secondary outcomes were composite all-cause death and kidney failure, severe relapse, and serious infection from 2 to 48 weeks after treatment initiation. To estimate the treatment effects, the Cox proportional hazard model and Fine-Gray subdistribution hazard model were used. RESULTS: In this emulated target trial, of 201 eligible patients (MPA, 175; GPA, 26), 6 (2.8%) died, 4 (2.0%) had kidney failure, 11 (5.3%) had severe relapse, and 40 (19.8%) had severe infections. Hazard ratios (HR) for IVMP 0.5 g/day and IVMP 1.0 g/day pulse groups compared with non-IVMP pulse were as follows: all-cause death = 0.46 (95% confidence interval [95%CI]: 0.07-2.81) and 0.07 (95%CI: 0.01-0.41); all-cause death/kidney failure = 1.18 (95%CI: 0.26-5.31) and 0.59 (95%CI: 0.08-4.52); subdistribution HRs for severe relapse = 1.26 (95%CI: 0.12-13.70) and 3.36 (95%CI: 0.49-23.29); and serious infection = 1.88 (95%CI: 0.76-4.65) and 0.94 (95%CI: 0.28-3.13). CONCLUSIONS: IVMP 1.0 g/day pulse may improve 48-week mortality in patients with severe MPA/GPA.
ABSTRACT
OBJECTIVES: To update an evidence base informing the 2024 JCR clinical practice guidelines (CPGs) for the management of rheumatoid arthritis (RA) in older adults. METHODS: Four clinical questions (CQs) regarding efficacy and safety of drug treatment were evaluated, with CQ1 addressing methotrexate (MTX), CQ2 biological disease-modifying antirheumatic drugs (bDMARDs), CQ3 Janus kinase (JAK) inhibitors, and CQ4 glucocorticoids (GCs). Quality of the evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS: Observational studies confirmed a pivotal role of MTX in the treatment of older RA patients. The meta-analysis showed that tumor necrosis factor inhibitors and JAK inhibitors were unequivocally effective in older RA patients. No data indicated that bDMARDs were unsafe for older patients. No safety data for JAK inhibitor use in older patients were available. One randomized controlled trial demonstrated that long-term treatment with low-dose GCs increased risks of GC-associated adverse events. The certainty of overall evidence was very low for all CQs. CONCLUSION: This systematic review provides the necessary evidence for developing 2024 JCR CPGs for managing older patients with RA. Continued updates on the evidence of JAK inhibitors and GC are desired.
ABSTRACT
OBJECTIVES: Late-onset rheumatoid arthritis (LORA), which has been increasing in recent years, lacks evidence for initial treatment. Japanese rheumatology experts recognized this gap and addressed it by developing consensus statements on the first clinical application of LORA. METHODS: These statements were created following an introductory discussion about treatment fundamentals, which included a review of existing literature and cohort data. The steering committee created a draft, which was refined using a modified Delphi method that involved panel members reaching a consensus. The panel made decisions based on input from geriatric experts, clinical epidemiologists, guideline developers, patient groups, and the LORA Research Subcommittee of the Japan College of Rheumatology. RESULTS: The consensus identified four established facts, three basic approaches, and six expert opinions for managing LORA. Methotrexate was recommended as the primary treatment, with molecular-targeted agents being considered if treatment goals cannot be achieved. An emphasis was placed on assessing the lives of older patients due to challenges in risk management and methotrexate accessibility caused by comorbidities or cognitive decline. CONCLUSIONS: The experts substantiated and refined 13 statements for the initial treatment of LORA. To validate these claims, the next is to conduct a registry study focusing on new LORA cases.

Salivary gland ultrasonography is a non-invasive imaging technique that helps in the diagnosis and assessment of disease activity in Sjögren's syndrome. However, it remains unclear whether the salivary gland ultrasonography findings are reversible in response to treatment. We present a case of a woman in her 20s who presented with parotid swelling and pain lasting for 3 months. The patient was diagnosed with anti-SS-A antibody-positive Sjögren's syndrome with active sialadenitis, and short-term glucocorticoid treatment resulted in resolution of clinical symptoms and improvement of salivary gland ultrasonography findings by the Outcome Measures in Rheumatology Clinical Trials scoring system. Notably, the anechoic/hypoechoic foci and vascular signals in the parotid and submandibular glands were reduced after treatment. Furthermore, peak systolic blood flow velocity of the facial artery entering the submandibular gland was decreased. Our case highlights that the findings of 'inflammatory' structural changes and vascularisation on salivary gland ultrasonography, including the Outcome Measures in Rheumatology Clinical Trials scoring system, reflect the disease active of Sjögren's syndrome and are reversible with treatment. Salivary gland ultrasonography has the potential to be a useful tool for monitoring treatment response and stratifying patients by disease activity in Sjögren's syndrome; therefore, further research is needed on the relationship of salivary gland ultrasonography findings with the pathophysiological mechanisms of sialadenitis and long-term clinical outcomes.

OBJECTIVE: We compared the incidence rates of hospitalized infections (HIs) between tocilizumab (TCZ) and other biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in adults aged ≥75 years with rheumatoid arthritis (RA). METHODS: We used a Japanese claims database from Medical Data Vision Co., Ltd (Tokyo, Japan) to perform a retrospective longitudinal population-based study in patients with RA who were prescribed b/tsDMARDs between 2014 and 2019. We calculated adjusted risk ratios (aRRs) for HIs in three age groups (<65, ≥65 and <75, and ≥75 years). RESULTS: Of 5506 patients, 2265 (41.1%) were <65 years, 1709 (31.0%) were 65-74 years, and 1532 (27.8%) were ≥75 years. Crude incidence rates (/100 person-years) of HIs were 3.99, 7.27, and 10.77, respectively. In the oldest group, aRRs (95% confidence interval) for HIs (b/tsDMARDs versus TCZ) were as follows: etanercept, 2.40 (1.24-4.61); adalimumab, 1.90 (0.75-4.83); golimumab, 1.21 (0.66-2.23); and abatacept, 0.89 (0.49-1.62). In the other age groups, the noticeable difference was a lower aRR of etanercept versus TCZ in the youngest group (0.30, 0.11-0.85). CONCLUSION: In patients with RA aged ≥75 years, b/tsDMARDs have a similar risk of HIs to tocilizumab except for etanercept.

OBJECTIVE: To compare healthcare resource utilisation (HCRU) and direct costs between responders vs non-responders to advanced therapies for rheumatoid arthritis (RA). METHODS: Patients initiating ≥1 advanced therapy (Oct 2018-Sept 2019) with ≥1 RA claim (6-month pre-index period), ≥2 RA claims (any period), and ≥12 months follow-up were identified from the Medical Data Vision claims database. HCRU and all-cause and RA-related costs (direct medical, emergency department [ED], laboratory, and pharmacy) were compared between responders vs non-responders. Adjusted incidence rate ratios (IRRs) for HCRU or cost were calculated via multivariable analyses. RESULTS: Among 2,446 patients (non-responders [n=1,817]; responders [n=629]), non-responders had significantly longer hospitalisation days (IRR: 1.8 [95% CI: 1.2-2.6]), and significantly more ED visits (2.5 [1.5-4.2]) and prescriptions (1.1 [1.1-1.2]). Mean all-cause hospital/outpatient medical costs were significantly higher for non-responders (1.4 [1.3-1.6], ¥530,895 vs ¥357,009 [$;3,992 vs $;2,684] for responders; ¥173,886 [$;1,307] difference); RA-related medical costs showed a similar trend (¥351,306 vs ¥253,030 [$;2,641 vs $1,902]; ¥98,276 [$;739] difference). No differences between responders and non-responders were observed in mean all-cause and RA-related pharmacy costs. CONCLUSIONS: Non-responders to advanced therapies had greater HCRU and all-cause/RA-related direct costs as compared with responders, suggesting a need for more effective RA therapies to reduce the economic burden associated with non-response.
ABSTRACT
OBJECTIVES: To identify the optimal dose of intravenous cyclophosphamide (IVCY) for induction therapy for anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS: We retrospectively assessed patients with AAV who received IVCY every 2-3 weeks during the remission induction phase. The associations of the IVCY dose with infection-free survival and relapse-free survival were analysed using a Cox regression model. We compared patients in three categories: very low-dose (VLD), low-dose (LD), and conventional dose (CD) (<7.5 mg/kg, 7.5-12.5 mg/kg, and >12.5 mg/kg, respectively). The non-linear association between IVCY dose and the outcomes were also evaluated. RESULTS: Of the 80 patients (median age 72 years), 12, 42, and 26 underwent the VLD, LD, and CD regimens, respectively, of whom 4, 3, and 7 developed infection or died. The adjusted hazard ratios for infection or death were 4.3 (95% confidence interval (CI) 0.94-19.8) for VLD and 5.1 (95% CI 1.21-21.3) for CD, compared with LD. We found the hazard ratio for infection or death increased when the initial IVCY dose exceeded 9 mg/kg. Relapse-free survival did not differ clearly. CONCLUSION: Low-dose IVCY (7.5-12.5 mg/kg) may result in fewer infections and similar relapse rates compared with the conventional regimen (>12.5 mg/kg).
ABSTRACT
OBJECTIVES: This study aimed to identify the challenges faced by nurses engaged in rheumatology care in Japan. METHODS: We conducted a questionnaire survey of nurses in Japan in 2020 on challenges experienced in rheumatology care. The participants were nurses certified by the Japan Rheumatism Foundation. Participants' answers were coded and categorized based on relevant phrases and words. Content analysis was performed on the findings. RESULTS: Responses were collected from 162 participants, and a total of 228 issues were identified. Eighteen categories with 56 subcategories emerged from the data analysis, which were grouped into five types of challenges: (1) communication, (2) understanding, (3) expertise, (4) system, and (5) collaboration. In particular, the results highlighted deficiencies in needs-based multidisciplinary team care. CONCLUSION: This study elucidated issues experienced by rheumatology nurses in clinical settings in Japan. Furthermore, this investigation revealed the necessity of patient-centered multidisciplinary team care, including health professionals, patients, and other relevant individuals. This study provided practical directions to facilitate the implementation of effective care focused on improving patients' quality of life.
ABSTRACT
OBJECTIVE: To clarify seasonal and other environmental effects on the onset of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS: We enrolled patients with new-onset eosinophilic granulomatosis with polyangiitis (EGPA), microscopic polyangiitis (MPA), and granulomatosis with polyangiitis (GPA) registered in the database of a Japanese multicenter cohort study. We investigated the relationship between environmental factors and clinical characteristics. Seasons were divided into 4 (spring, summer, autumn, and winter), and the seasonal differences in AAV onset were analyzed using Pearson chi-square test, with an expected probability of 25% for each season. RESULTS: A total of 454 patients were enrolled, with a mean age of 70.9 years and a female proportion of 55.5%. Overall, 74, 291, and 89 patients were classified as having EGPA, MPA, and GPA, respectively. Positivity for myeloperoxidase (MPO)-ANCA and proteinase 3 (PR3)-ANCA was observed in 355 and 46 patients, respectively. Overall, the seasonality of AAV onset significantly deviated from the expected 25% for each season (P = 0.001), and its onset was less frequently observed in autumn. In ANCA serotypes, seasonality was significant in patients with MPO-ANCA (P < 0.001), but not in those with PR3-ANCA (P = 0.97). Additionally, rural residency of patients with AAV was associated with PR3-ANCA positivity and biopsy-proven pulmonary vasculitis. CONCLUSION: The onset of AAV was influenced by seasonal variations and was less frequently observed in autumn. In contrast, the occurrence of PR3-ANCA was triggered, not by season, but by rural residency.

A woman diagnosed with rheumatoid arthritis and treated with Janus kinase (JAK) inhibitors presented with a gradually enlarging bilateral submandibular lymph nodes swelling that had lasted several weeks. A lymph node biopsy showed epithelioid granulomatous lymphadenitis with caseous necrosis. Mycobacteria grew in acid-fast bacteria culture and were identified as Mycobacterium avium by polymerase chain reaction. The patient was diagnosed with cervical lymphadenitis caused by M. avium. A computed tomography scan showed no evidence of a mass or infection at other sites, including the lungs; therefore, the mass was excised without any antimicrobial treatments. Her neck mass had not recurred at 9 months after the excision. JAK inhibitors have emerged as an important new class of oral therapy for rheumatoid arthritis and other diseases. Physicians should be aware of the relatively rare complications, such as cervical lymphadenitis caused by nontuberculous mycobacteria, when using JAK inhibitors.

OBJECTIVES: To investigate the association between decreased serum IgG levels caused by remission-induction immunosuppressive therapy of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and the development of severe infections. METHODS: We conducted a retrospective cohort study of patients with new-onset or severe relapsing AAV enrolled in the J-CANVAS registry, which was established at 24 referral sites in Japan. The minimum serum IgG levels up to 24 weeks and the incidence of severe infection up to 48 weeks after treatment initiation were evaluated. After multiple imputations for all explanatory variables, we performed the multivariate analysis using a Fine-Gray model to assess the association between low IgG (the minimum IgG levels <500 mg/dl) and severe infections. In addition, the association was expressed as a restricted cubic spline (RCS) and analysed by treatment subgroups. RESULTS: Of 657 included patients (microscopic polyangiitis, 392; granulomatosis with polyangiitis, 139; eosinophilic granulomatosis with polyangiitis, 126), 111 (16.9%) developed severe infections. The minimum serum IgG levels were measured in 510 patients, of whom 77 (15.1%) had low IgG. After multiple imputations, the confounder-adjusted hazard ratio of low IgG for the incidence of severe infections was 1.75 (95% confidence interval: 1.03-3.00). The RCS revealed a U-shaped association between serum IgG levels and the incidence of severe infection with serum IgG 946 mg/dl as the lowest point. Subgroup analysis showed no obvious heterogeneity between treatment regimens. CONCLUSION: Regardless of treatment regimens, low IgG after remission-induction treatment was associated with the development of severe infections up to 48 weeks after treatment initiation.

BACKGROUND: Interstitial lung disease (ILD) is a common complication of connective tissue diseases (CTD), but there are few clinical trials to guide disease management. We aimed to develop expert consensus statements and an algorithm for CTD-ILD management. RESEARCH DESIGN AND METHODS: Based on a targeted literature review, we developed 109 statements on managing CTD-ILD across six domains. We used a modified Delphi process to survey 22 physicians in Japan involved in managing CTD-ILD (specialists in pulmonology, rheumatology, pathology, and radiology). These panelists participated in two rounds of web-based survey to establish consensus statements, which were used to define an algorithm. Consensus was defined as a mean value ≥70 on a scale of 0 (strong disagreement) to 100 (strong agreement). RESULTS: Between May-August 2022, consensus was reached on 93 statements on CTD-ILD management. The most important consensus statements included screening CTD patients for ILD (typically with high-resolution computed tomography), using imaging, pulmonary function testing and serum biomarkers for diagnosis and severity assessment, regularly following up patients, and multidisciplinary management of CTD-ILD. Consensus statements were interpreted into an algorithm for clinical guidance. CONCLUSIONS: Using the Delphi process, we have developed consensus statements and an algorithm to guide clinical decision-making for CTD-ILD.

OBJECTIVES: The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPGs) for the management of rheumatoid arthritis (RA) and prepare an algorithm for non-drug and surgical treatments. This article is a digest version of the guidelines. METHODS: The Japanese Ministry of Health, Labour and Welfare's research group, in collaboration with the JCR, used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. The consensus was formed by CPG panel members. RESULTS: We raised 19 clinical questions regarding non-drug and surgical treatments for RA and developed recommendations. The treatments included exercise therapy; occupational therapy; joint injection of corticosteroids; and orthopaedic surgeries including cervical spine surgery, wrist and foot arthroplasty, ankle arthrodesis, and replacement arthroplasty of the shoulder, elbow, finger, hip, knee, and ankle. Recommendations regarding the risks of surgery and perioperative discontinuation of medications have also been developed. Based on these recommendations, we created an original algorithm for the non-drug and surgical treatment of RA. CONCLUSIONS: These recommendations are expected to serve rheumatologists, health care professionals, and patients with RA as tools for shared decision-making to treat residual limb joint symptoms and functional impairment.
