RESUMEN
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.
RESUMEN
INTRODUCTION: Although synthetic glucocorticoids (GCs) are commonly used to treat autoimmune and other diseases, GC induced osteoporosis (GIOP) which accounts for 25% of the adverse reactions, causes fractures in 30-50% of patients, and markedly decreases their quality of life. In 2014, the Japanese Society for Bone and Mineral Research (JSBMR) published the revised guidelines for the management and treatment of steroid-induced osteoporosis, providing the treatment criteria based on scores of risk factors, including previous fractures, age, GC doses, and bone mineral density, for patients aged ≥18 years who are receiving GC therapy or scheduled to receive GC therapy for ≥3 months. MATERIALS AND METHODS: The Committee on the revision of the guidelines for the management and treatment of GIOP of the JSBMR prepared 17 clinical questions (CQs) according to the GRADE approach and revised the guidelines for the management and treatment of GIOP through systematic reviews and consensus conferences using the Delphi method. RESULTS: Bisphosphonates (oral and injectable formulations), anti-RANKL antibody teriparatide, eldecalcitol, or selective estrogen receptor modulators are recommended for patients who has received or scheduled for GC therapy with risk factor scores of ≥3. It is recommended that osteoporosis medication is started concomitantly with the GC therapy for the prevention of fragility fractures in elderly patients. CONCLUSION: The 2023 guidelines for the management and treatment of GIOP was developed through systematic reviews and consensus conferences using the Delphi method.

OBJECTIVE: The objective of the study was to develop a nursing practice scale for rheumatoid arthritis treatment with biological disease-modifying anti-rheumatic drugs. METHODS: An anonymous self-administered questionnaire survey was administered to 1826 nurses, 960 of whom were Certified Nurses by Japan Rheumatism Foundation (CNJRFs) and 866 were registered nurses (RNs). Using exploratory factor analysis, criterion validity, and known-groups technique, we assessed the reliability and validity of the self-created 19-item nursing practice scale to evaluate the care provided to patients with rheumatoid arthritis receiving biological disease-modifying anti-rheumatic drugs based on the nurse's role as clarified from a literature review of relevant studies. RESULTS: A total of 698 (38.4%) responses were collected from 407 CNJRFs and 291 RNs. Exploratory factor analysis was conducted on 18 items to examine three factors: 'nursing to enhance patients' capacity for self-care', 'nursing in which patients participate in decision-making', and 'nursing in which team medical care is promoted'. Cronbach's α was .95. The Spearman's coefficient was ρ = .738 for criterion validity. Using the known-groups technique, CNJRFs had higher total scale scores than RNs (P < .05). CONCLUSIONS: The results confirmed the reliability, criterion validity, and construct validity of the scale.

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.
RESUMEN
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.

OBJECTIVES: To efficiently detect somatic UBA1 variants and establish a clinical scoring system predicting patients with pathogenic variants in VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome. METHODS: Eighty-nine Japanese patients with clinically suspected VEXAS syndrome were recruited [81 males and 8 females; median onset age (IQR) 69.3 years (62.1-77.6)]. Peptide nucleic acid-clamping PCR (PNA-PCR), regular PCR targeting exon 3 clustering UBA1 variants, and subsequent Sanger sequencing were conducted for variant screening. Partitioning digital PCR (pdPCR) or targeted amplicon deep sequencing (TAS) was also performed to evaluate the variant allele frequency (VAF). We developed our clinical scoring system to predict UBA1 variant-positive and negative patients and assessed the diagnostic value of our system using receiver operating characteristic (ROC) curve analysis. RESULTS: Forty patients with reported pathogenic UBA1 variants (40/89, 44.9%) were identified, including a case having a variant with VAF of 1.7%, using a highly sensitive method. Our clinical scoring system considering >50 years of age, cutaneous lesions, lung involvement, chondritis, and macrocytic anaemia efficiently predicted patients with UBA1 variants (the area under the curve for the scoring total was 0.908). CONCLUSIONS: Genetic screening with the combination of regular PCR and PNA-PCR detected somatic UBA1 variants with high sensitivity and specificity. Our scoring system could efficiently predict patients with UBA1 variants.
RESUMEN
OBJECTIVES: To address improvements in quality of life (QOL), we analysed the relative contributions of factors to EuroQol 5 Dimensions (EQ-5D) in abatacept-treated rheumatoid arthritis (RA) patients in the ORIGAMI study. METHODS: Patients who were evaluable for disease activity through to Week 52 in the ORIGAMI study were divided into those achieving Simplified Disease Activity Index-remission/low disease activity (remission/LDA; n=178) and patients with moderate/high disease activity (MDA/HDA; n=99). We compared the changes in EQ-5D and other outcomes through to Week 52. Focusing on the remission/LDA group, the contribution of each factor to the variance of EQ-5D at baseline and Week 52 was examined using analysis of variance. RESULTS: The remission/LDA group showed greater improvements than the MDA/HDA group in EQ-5D, Japanese Health Assessment Questionnaire, visual analogue scale for pain (Pain VAS), and patient global assessment (PtGA). In the remission/LDA group, factors significantly contributing to EQ-5D were sex, C-reactive protein, and Pain VAS at baseline, and PtGA and age at Week 52. CONCLUSIONS: In RA patients who achieved remission/LDA during abatacept treatment, PtGA and age at Week 52 contribute to the variance of EQ-5D, suggesting that identification of factors associated with PtGA may be important to address improvements of QOL.
RESUMEN
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.

OBJECTIVE: The aim of this study was to update the Japan College of Rheumatology (JCR) clinical practice guidelines (CPG) for the management of rheumatoid arthritis (RA; JCR CPG for RA) according to recent changes in the medical environment in Japan. This article is a digest version of the guidance. METHODS: We used the Grading of Recommendations, Assessment, Development, and Evaluation method to update the 2014 JCR CPG for RA. A consensus was formed by CPG panel members. RESULTS: We identified 36 important clinical questions regarding drug treatment and developed corresponding recommendations for RA. The recommendations included the following RA medications: non-steroidal anti-inflammatory drugs, corticosteroids, conventional synthetic disease-modifying antirheumatic drugs, biological disease-modifying antirheumatic drugs, anti-receptor activator for nuclear factor-κB ligand antibodies, and Janus kinase inhibitors, as well as the tapering and discontinuation of these medications. Recommendations regarding the efficacy and safety of treatments in the elderly and patients with comorbidities were also developed. Finally, we used these recommendations to create an original algorithm for drug treatment for RA based on the Treat-to-Target approach. CONCLUSION: The 2020 JCR CPG for RA provides a useful tool for rheumatologists, health care professionals, and patients with RA, enabling shared decision-making in a variety of clinical situations.

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).
RESUMEN
PURPOSE: Autoantibodies (aAbs) to type I interferons (IFNs) have been found in less than 1% of individuals under the age of 60 in the general population, with the prevalence increasing among those over 65. Neutralizing autoantibodies (naAbs) to type I IFNs have been found in at least 15% of patients with life-threatening COVID-19 pneumonia in several cohorts of primarily European descent. We aimed to evaluate the prevalence of aAbs and naAbs to IFN-α2 or IFN-ω in Japanese patients who suffered from COVID-19 as well as in the general population. METHODS: Patients who suffered from COVID-19 (n = 622, aged 0-104) and an uninfected healthy control population (n = 3,456, aged 20-91) were enrolled in this study. The severities of the COVID-19 patients were as follows: critical (n = 170), severe (n = 235), moderate (n = 112), and mild (n = 105). ELISA and ISRE reporter assays were used to detect aAbs and naAbs to IFN-α2 and IFN-ω using E. coli-produced IFNs. RESULTS: In an uninfected general Japanese population aged 20-91, aAbs to IFNs were detected in 0.087% of individuals. By contrast, naAbs to type I IFNs (IFN-α2 and/or IFN-ω, 100 pg/mL) were detected in 10.6% of patients with critical infections, 2.6% of patients with severe infections, and 1% of patients with mild infections. The presence of naAbs to IFNs was significantly associated with critical disease (P = 0.0012), age over 50 (P = 0.0002), and male sex (P = 0.137). A significant but not strong correlation between aAbs and naAbs to IFN-α2 existed (r = - 0.307, p value < 0.0001) reinforced the importance of measuring naAbs in COVID-19 patients, including those of Japanese ancestry. CONCLUSION: In this study, we revealed that patients with pre-existing naAbs have a much higher risk of life-threatening COVID-19 pneumonia in Japanese population.

OBJECTIVES: This study aimed to quantify nailfold capillary (NFC) abnormalities in anti-melanoma differentiation-associated gene 5 (MDA5) -positive DM patients and to evaluate the association with clinical parameters, including serum biomarkers. In addition, we aimed to clarify the period leading to remission of NFC abnormalities during immunosuppressive treatment in patients with DM. METHODS: A prospective observational study was conducted including patients (n = 10) who first visited Hiroshima University Hospital and were diagnosed with DM or clinically amyopathic DM with anti-MDA5 antibodies. We compared the NFC abnormalities detected by nailfold-video capillaroscopy (NVC), physical findings, blood tests, respiratory function tests, and vascular-related growth factors measured using a LEGENDplexTM Multi-Analyte Flow Assay Kit. RESULTS: NFC abnormalities improved in all patients from 2 to 17 weeks after the initiation of immunosuppressive treatment. The NVC scores were inversely correlated with anti-MDA5 antibody titres at baseline. NVC scores and forced vital capacity were positively correlated. Baseline values of M-CSF and stem cell factor were correlated with anti-MDA-5 titres. CONCLUSION: Our study suggested that NVC scores and disease activity were inversely correlated before treatment. Vascular-related growth factors, such as M-CSF and stem cell factor, may be associated with the disease mechanism in patients with anti-MDA5 antibody-positive DM.

OBJECTIVE: To compare the outcome of various treatment de-escalation regimens in patients with RA who achieved sustained remission. METHODS: At period 1, 436 RA patients who were treated with MTX and bDMARDs and had maintained DAS28(ESR) at <2.6 were divided into five groups based on shared patient/physician decision-making; continuation, dose reduction and discontinuation of MTX or bDMARDs. At end of year 1, patients who achieved DAS28(ESR) <3.2 were allowed to enrol in period 2 for treatment using the de-escalation regimens for another year. The primary and secondary endpoints were the proportion of patients with DAS28(ESR) <2.6 at year 1 and 2, respectively. RESULTS: Based on shared decision-making, 81.4% elected de-escalation of treatment and 48.4% selected de-escalation of MTX. At end of period 1, similar proportions of patients maintained DAS28(ESR) <2.6 (continuation, 85.2%; MTX dose reduction, 79.0%; MTX-discontinuation, 80.0%; bDMARD dose reduction, 73.9%), although the rate was significantly different between the continuation and bDMARD-discontinuation. At end of period 2, similar proportions of patients of the MTX groups maintained DAS28(ESR) <2.6 (continuation or de-escalation), but the rates were significantly lower in the bDMARD-discontinuation group. However, half of the latter group satisfactorily discontinued bDMARDs. Adverse events were numerically lower in MTX and bDMARD-de-escalation groups during period 1 and 2, compared with the continuation group. CONCLUSIONS: After achieving sustained remission by combination treatment of MTX/bDMARDs, disease control was achieved comparably by continuation, dose reduction or discontinuation of MTX and dose reduction of bDMARDs at end of year 1. Subsequent de-escalation of MTX had no impacts on disease control but decreased adverse events in year 2.

INTRODUCTION: Lipopolysaccharide (LPS) contamination of commercially available proteins has seriously impeded research on citrullinated fibrinogen (cit-Fb) in rheumatoid synovial cells (RSCs). METHODS: RSCs obtained from 4 rheumatoid arthritis patients who underwent full knee arthroplasty were cultured, stimulated with cit-Fb, and cytokine expression levels were measured. We then evaluated polymyxin-B (PMB), heat inactivation, and rough (R)-type LPS mutants for rapid detection of LPS contamination. RESULTS: cit-Fb induced expression of CXCL10 and IFNB in RSCs via the toll-like receptor. PMB inhibited cit-Fb-mediated CXCL10 gene expression but not protein expression induced by 20 µg/mL cit-Fb. Heat inactivation did not affect LPS-mediated CXCL10 or IL-6 induction; however, cit-Fb-mediated CXCL10expression was inhibited. Wild-type LPS from Escherichia coli (WT-LPS) strongly induces CXCL10 expression, but induction by Ra-LPS was weak, and induction by Rc- and Re-LPS was minimal. Re-LPS suppression of WT-LPS-mediated CXCL10 induction in RSCs and peripheral blood monocytes (PBMs) was dose dependent. Furthermore, Re-LPS completely suppressed cit-Fb-mediated CXCL10 induction in RSCs and PBMs. CONCLUSION: To easily identify LPS contamination during routine experiments, our results suggest that Re-LPS is a better tool for rapid detection of LPS contamination compared to PMB and heat treatment.

Introduction: Immunoglobulin G4-related disease (IgG4-RD) responds well to glucocorticoids but is often associated with relapses. Interleukin (IL)-4 and IL-13 are involved in the pathogenesis of IgG4-RD. We present the first case in which dupilumab was an effective adjunct treatment for a patient with steroid-dependent IgG4-RD complicated by asthma.Case study: A 57-year-old man was referred to our hospital for further investigation and treatment of proptosis with neck swelling in 2019. He developed a cough and swelling of the neck in 2016. He was diagnosed with asthma in 2017 and started receiving inhaled glucocorticoids and a long-acting beta-agonist. The patient started receiving oral prednisolone at a dose of 20 mg/day. Oral prednisolone reduced his symptoms, but he relapsed when treatment was tapered to less than 10 mg/day. He was diagnosed with IgG4-RD through a parotid gland biopsy.Results: Azathioprine was given to reduce systemic glucocorticoids. The prednisolone dose was gradually tapered to 10 mg/day, resulting in the relapse of proptosis and an asthma attack. We added dupilumab, and his asthma symptoms and proptosis improved. Serum IgG4 levels continued to decrease, and the prednisolone dose was tapered to 2 mg.Conclusion: Dupilumab might be useful as an adjunctive treatment for patients with steroid-dependent IgG4-RD complicated by asthma. Serum IgG4 levels can be used as a marker to monitor dupilumab treatment in IgG4-RD.

OBJECTIVES: Cyclophosphamide (CYC) has been proposed as a standard induction regimen for interstitial lung disease (ILD) associated with systemic sclerosis (SSc). However, there remain patients with SSc-ILD who are intractable to the therapy. This study aimed to identify factors associated with inadequate response to CYC and investigate how to treat SSc-ILD, especially in the need for glucocorticoids (GCs) combined with CYC. METHODS: This retrospective study included consecutive patients diagnosed with SSc-ILD and treated with CYC between 2009 and 2020. Logistic regression models were used to determine the prognostic factors indicating significant progression of ILD (SP-ILD). The clinical findings of patients treated with vs. without GCs were compared. RESULTS: Nineteen patients were registered, with a median age of 61.0 years. Fifteen were females, and five were classified into SP-ILD. Baseline high C-reactive protein (CRP) levels and non-widespread or localized ground-glass opacities (GGOs) predicted SP-ILD in multivariable analyses, and the cut-off level of CRP was 0.41 mg/dL. In clinical courses, SSc-ILD with high inflammation temporarily responded to CYC, regardless of the combined use of GCs; however, the therapeutic effects deteriorated soon after stopping CYC. CONCLUSION: High CRP levels with non-widespread GGO predicted progressive ILD in patients with SSc treated with CYC.

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

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

OBJECTIVES: To 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.

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.
