RESUMO
OBJECTIVE: To revise the 2017 clinical practice guidelines (CPG) for the management of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) to reflect advancements in the field. METHODS: Similar to the 2017 CPG, the Grading of Recommendations, Assessment, Development, and Evaluation system was adopted for this revision. The intended users of this CPG include patients diagnosed with MPA or GPA in Japan and their families and healthcare professionals, including specialists and non-specialists. Based on a scoping review, four clinical questions (CQs) of the 2017 guidelines were modified, and six new CQs were added. RESULTS: We suggest a combination of glucocorticoid and cyclophosphamide or rituximab for remission induction therapy. In cases where cyclophosphamide or rituximab is used, we suggest the use of avacopan over high-dose glucocorticoid. Furthermore, we suggest against the use of plasma exchange in addition to the standard treatment in severe cases of MPA/GPA. Finally, we suggest the use of glucocorticoid and rituximab over glucocorticoid and azathioprine for remission maintenance therapy. CONCLUSIONS: The recommendations have been updated based on patient preference, certainty of evidence, benefit and risk balance, and cost.

OBJECTIVE: This study aimed to evaluate the Ministry of Health, Labour and Welfare (MHLW) diagnostic criteria for antineutrophil cytoplasmic antibody-associated vasculitis compared to the new American College of Rheumatology/European Alliance of Associations for Rheumatology 2022 criteria. METHODS: Two nationwide cohort studies were used, and participants were categorised as having eosinophilic granulomatosis with polyangiitis, granulomatosis with polyangiitis (GPA), or microscopic polyangiitis (MPA) according to the American College of Rheumatology/European Alliance of Associations for Rheumatology 2022 and MHLW criteria. RESULTS: Of the entire patient population, only 10 (2.1%) were unclassifiable according to the MHLW probable criteria, while a significant number of patients (71.3%) met at least two criteria. The MHLW probable criteria for MPA had some challenges in differentiating between MPA and eosinophilic granulomatosis with polyangiitis, and the same was true for MHLW probable criteria for GPA in differentiating MPA from GPA. Nevertheless, improved classification results were obtained when the MHLW probable criteria were applied in the order of eosinophilic granulomatosis with polyangiitis, MPA, and GPA. CONCLUSIONS: The application of MHLW criteria could categorise a substantial number of patients with antineutrophil cytoplasmic antibody-associated vasculitis into one of the three antineutrophil cytoplasmic antibody-associated vasculitis diseases. The classification was in accordance with the American College of Rheumatology/European Alliance of Associations for Rheumatology 2022 criteria when considering the order of application.

OBJECTIVE: The objective of this study was to compare the American College of Rheumatology/European Alliance of Associations for Rheumatology 2022 criteria with the previous classification algorithm for anti-neutrophil cytoplasmic antibody-associated vasculitis. METHODS: We used data from two nationwide, prospective, inception cohort studies. The enrolled patients were classified as having eosinophilic granulomatosis with polyangiitis (EGPA), granulomatosis with polyangiitis (GPA), or microscopic polyangiitis (MPA) according to the new criteria; these criteria were compared with Watts' algorithm. RESULTS: Among 477 patients, 10.7%, 9.9%, and 75.6% were classified as having EGPA, GPA, and MPA, respectively; 6.1% were unclassifiable. Three patients met both the EGPA and MPA criteria, and eight patients met both the GPA and MPA criteria. Of 78 patients with GPA classified using Watts' algorithm, 27 (34.6%) patients were reclassified as having MPA. Ear, nose, and throat involvement was significantly less frequent in patients reclassified as having MPA than in those reclassified as having GPA. Of 73 patients unclassifiable using Watts' algorithm, 62 were reclassified as having MPA. All patients reclassified as having MPA were myeloperoxidase-anti-neutrophil cytoplasmic antibody positive, and 46 had interstitial lung disease. CONCLUSION: Although the American College of Rheumatology/European Alliance of Associations for Rheumatology 2022 criteria cause overlapping multiple criteria fulfilments in some patients, those items contribute to classifying unclassifiable patients using Watts' algorithm into MPA.

OBJECTIVES: The aim of this article is to evaluate the effectiveness and safety of rituximab (RTX) for microscopic polyangiitis and granulomatosis with polyangiitis in Japan. METHODS: In this prospective observational study, all patients with microscopic polyangiitis and granulomatosis with polyangiitis administered RTX were enrolled at each institution. During the observation period of 2 years, data up to 6 months were analysed. Cox proportional hazards analysis was used to assess the factors associated with an outcome. RESULTS: Of the 75 patients who received RTX for remission induction therapy, 53 achieved remission by the sixth month and 50 were in remission at the sixth month. During therapy, 38 serious adverse events were observed in 24 patients, 21 serious infections in 16 patients, and 9 patients died. No factors were associated with remission; however, there was a significant difference between patients with and without remission in serious adverse events (22.6% vs. 54.5%), serious infections (11.3% vs. 45.4%), and death (1.9% vs. 36.4%). The hazard ratio (95% confidence interval) for serious infection was 3.49 (1.29-9.74) for patients aged ≥ 75 years and 3.53 (1.31-9.53) for pulmonary complications. Four patients maintained remission for 6 months. CONCLUSIONS: The effectiveness and safety of RTX for microscopic polyangiitis and granulomatosis with polyangiitis for up to 6 months was demonstrated.

OBJECTIVES: We conducted a descriptive study of the physicians' evidence-practice gap for adults covered by the 2017 clinical practice guidelines for the management of antineutrophil cytoplasmic antibody-associated vasculitis in Japan. METHODS: This web-based survey, conducted between January and February 2021, involved physicians who had treated at least five patients in the preceding year at a regional core hospital. The outcome was the physicians' experience in treating patients with microscopic polyangiitis or granulomatosis with polyangiitis [prevalence with 95% confidence intervals (CIs)], defined as treating at least 60% of their patients with the recommended therapy during the year. A modified Poisson regression analysis was performed to explore the factors associated with concordance. RESULTS: The 202 participants included 49 pulmonologists, 65 nephrologists, 61 rheumatologists, and other physicians. The concordance was 31.5% (95% CI, 25.1-38.5) of physicians who used cyclophosphamide or rituximab for the induction of remission. Rheumatology showed the highest concordance with published evidence (risk ratio = 2.4; 95% CI, 1.10-5.22, p = .03). CONCLUSIONS: These results suggest an evidence-practice gap, which varies substantially among subspecialties. Further studies and a new promotional initiative are necessary to close this gap in clinical practice.

OBJECTIVES: The objective of this study is to provide evidence for the revision of clinical practice guidelines for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis by the Japan Research Committee for Intractable Vasculitis. METHODS: PubMed, CENTRAL, and the Japan Medical Abstracts Society databases were searched for articles published between 2015 and 2020 to update the systematic review for existing clinical questions, while PubMed, CENTRAL, EMBASE, and the Japan Medical Abstracts Society were searched for articles published between 2000 and 2020 to conduct a systematic review for newly developed clinical questions. The certainty of evidence was assessed with the GRADE approach. RESULTS: For remission induction, when used in conjunction with cyclophosphamide or rituximab, reduced-dose glucocorticoid lowered the risk of serious adverse events compared to standard-dose glucocorticoid. Avacopan improved sustained remission at 12 months compared to high-dose glucocorticoid. Addition of plasma exchange to remission induction therapy did not reduce the risk of death, end-stage kidney disease, or relapse. For remission maintenance, rituximab reduced the risk of relapse compared to azathioprine. Long-term rituximab or azathioprine reduced the risk of relapse compared to short-term rituximab or azathioprine, respectively. CONCLUSIONS: This systematic review provided evidence required to develop the 2023 clinical practice guideline for the management of ANCA-associated vasculitis.

OBJECTIVES: In Japan, clinical records of patients with intractable diseases, including microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), are compiled into a database. This study aimed to understand the current treatment status and changes in treatment regimens from our previous survey. METHODS: Using data from 2012 and 2013, patients with new-onset MPA and GPA were extracted and analysed. RESULTS: We analysed 1278 MPA and 215 GPA patients. The average age was 71.7 and 62.7 years, respectively. Methylprednisolone pulse therapy was used in 51.2% of MPA patients and 40.5% of GPA patients; the initial prednisolone-equivalent glucocorticoid dose was 39.5 mg/day in MPA and 46.6 mg/day in GPA. Concomitant intravenous or oral cyclophosphamide (CY) was administered to 22.6% of MPA and 56.3% of GPA. Young age, bloody sputum, low serum creatinine, and high C-reactive protein levels were independently associated with CY use in MPA. Compliance with treatment protocol for Japanese patients with myeloperoxidase (MPO)-anti-neutrophilic cytoplasmic antibody-associated vasculitis study criteria or the 2011 clinical practice guidelines for rapidly progressive glomerulonephritis was 42.7% and 49.7%, respectively. CONCLUSIONS: MPA was more prevalent than GPA in the registry. Compared to patients with GPA, MPA patients were older and used CY less frequently. No apparent changes in treatment trends were observed from the previous survey.

BACKGROUND: Although it is known that malignancies can be associated with dermatomyositis, there are few reports on dermatomyositis associated with prostate cancer with neuroendocrine differentiation. CASE PRESENTATION: A 63-year-old man visited our hospital due to pollakiuria. High levels of PSA and NSE were observed, and prostate biopsy revealed an adenocarcinoma with neuroendocrine differentiation. Multiple metastases to the lymph nodes, bones, and liver were identified, and androgen deprivation therapy (ADT) was started immediately. Following 2 weeks of treatment, erythema on the skin, and muscle weakness with severe dysphagia appeared. The patient was diagnosed with dermatomyositis, and high-dose glucocorticoid therapy was initiated. ADT and subsequent chemotherapy with etoposide and cisplatin (EP) were performed for prostate cancer, which resulted in decreased PSA and NSE and reduction of all metastases. After the initiation of EP therapy, dermatomyositis improved, and the patient regained oral intake function. Although EP therapy was replaced by docetaxel, abiraterone, and enzalutamide because of adverse events, no cancer progression was consistently observed. Dermatomyositis worsened temporarily during the administration of abiraterone, but it improved upon switching from abiraterone to enzalutamide and dose escalation of glucocorticoid. CONCLUSIONS: We successfully treated a rare case of dermatomyositis associated with prostate adenocarcinoma with neuroendocrine differentiation.

Clinical trials and observational studies have established cyclophosphamide (CY) or rituximab plus glucocorticoid (GC) as standard remission induction therapies in patients with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA). However, because these regimens are associated with serious adverse drug reactions, the development of drugs with novel mechanisms of actions are needed. Progress in basic and clinical research has identified novel candidate targeting molecules, including B-cell activating factor (BAF), C5a receptor, and interleukin-6. The combination of rituximab and BAF blockade in patients with MPA and GPA is under investigation in an effort to strike a better benefit-risk balance. Phase II clinical trials of avacopan (CCX168), an orally administered C5a receptor antagonist, have suggested a reduction in the dosage of concomitant GC or the replacement of GC in patients with MPA and GPA. The results from a currently ongoing phase III trial are awaited. Anecdotal case reports and an open-label pilot study have indicated the effectiveness of tocilizumab in patients with MPA and GPA. A randomized clinical trial comparing tocilizumab and intravenous CY in combination with GC is currently in progress. Molecular targeted therapy is expected to transform the treatment strategy for MPA and GPA to allow GC-free or at least less GC-dependent forms of therapy.

OBJECTIVES: To provide evidence for the revision of clinical practice guideline (CPG) for the management of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) by the Japan Research Committee for Intractable Vasculitis. METHODS: PubMed, CENTRAL, and the Japan Medical Abstracts Society were searched for articles published between January 1994 and January 2015 to conduct systematic review (SR), and the quality of evidence was assessed with GRADE approach. RESULTS: Nine randomized controlled trials (RCTs) and two non-RCTs were adopted for remission induction therapy, three RCTs and two non-RCTs for plasma exchange, and five RCTs and one non-RCT for remission maintenance therapy. A significant difference was found in efficacy and safety for the following comparisons. In the non-RCT adopted for remission induction therapy, glucocorticoid (GC) + cyclophosphamide (CY) was significantly superior to GC monotherapy regarding remission. GC + intravenous CY for remission induction therapy was superior to GC + oral CY regarding death at one year, serious adverse events, and serious infection. Concomitant use of plasma exchange for remission induction therapy of AAV with severe renal dysfunction reduced risk of end-stage renal disease versus non-users at month 3. CONCLUSION: This SR provided necessary evidence for developing CPG for the management of ANCA-associated vasculitis.

OBJECTIVE: The Japan Research Committee for Intractable Vasculitis has fully revised the clinical practice guidelines (CPG) for the management of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) to improve and standardize the medical treatment of the disease in Japan. METHODS: The previous CPG was published in a classical review style in Japanese in 2011 and 2014. We adopted the Grading of Recommendations Assessment, Development and Evaluation system for this revision, and various stakeholders, including patients, participated in it. The expected users of this CPG are AAV patients in Japan and their families and healthcare professionals, including both AAV specialists and non-specialists. We set clinical questions concerning the three important clinical topics of remission induction therapy, plasma exchange, remission maintenance therapy, and developed eight recommendation statements. RESULTS: For remission induction therapy for newly developed AAV, we weakly recommend glucocorticoid (GC) plus intravenous cyclophosphamide pulse (IVCY) or oral cyclophosphamide (POCY) rather than GC alone, and IVCY rather than POCY. We also weakly recommend CY rather than rituximab. In the case of AAV with severe renal impairment, we weakly recommend plasma exchange as a conjunction therapy. We weakly recommend azathioprine for remission maintenance therapy. CONCLUSION: The revised CPG has demonstrated evidence-based treatment recommendations for AAV.

OBJECTIVE: It is controversial whether the use of biological disease-modifying antirheumatic drugs (DMARDs) increases the risk of herpes zoster (HZ). We aimed to evaluate the risks of HZ in tumor necrosis factor inhibitor (TNFI) and non-TNFI users with rheumatoid arthritis (RA) over 3 years in Japan. METHOD: Using the Japanese health insurance database, we assigned patients with at least one RA diagnostic code and one prescription for any DMARDs (RA cases) recorded between January 2005 and December 2013 to the RA group. We randomly selected five age-, sex-, calendar year- and observation length-matched non-RA cases for each RA case (non-RA group), and assessed associations between RA and HZ. To evaluate the risks of HZ in TNFI and non-TNFI users, we conducted a nested case-control study (NCC) in the RA group. RESULTS: The RA group (n = 6712) had a significantly higher crude incidence rate of HZ than the non-RA group (n = 33 560) (14.2 vs. 8.3/1000 patient-years), and the adjusted odds ratio (95% confidence interval) of the RA versus non-RA groups was 1.43 (1.17-1.75). The NCC demonstrated that use of TNFI, non-TNFI, methotrexate, or immunosuppressive DMARDs did not increase the risks of HZ. Use of corticosteroid ≥ 5 mg/day conveyed a significant risk of HZ in patients with RA. CONCLUSIONS: Rheumatoid arthritis was significantly associated with the development of HZ, and use of corticosteroids ≥ 5 mg/day was identified as a significant risk factor, whereas either TNFI or non-TNFI use were not.

ETS proto-oncogene 1, transcription factor (ETS1) is involved in various immune responses. Genome-wide association studies on systemic lupus erythematosus in Chinese populations identified the association of ETS1 polymorphism in 3' untranslated region, rs1128334A, which was associated with lower ETS1 expression. In view of substantial sharing of susceptibility genes across multiple autoimmune diseases, we examined whether ETS1 is associated with a rare autoimmune rheumatic disease, anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Association of rs1128334 was tested in 466 Japanese patients with AAV and 1099 healthy controls by logistic regression analysis under the additive model. AAV patients were classified into 285 microscopic polyangiitis (MPA), 92 granulomatosis with polyangiitis (GPA), 56 eosinophilic GPA, and 33 unclassifiable AAV, according to the European Medicines Agency (EMEA) algorithm. Among the patients, 376 were positive for MPO-ANCA and 62 for PR3-ANCA. When the patients were classified according to the EMEA classification, rs1128334A allele was significantly increased in GPA (P = 0.0060, P c = 0.030, odds ratio (OR), 1.54; 95% confidence interval (CI), 1.13-2.10). With respect to the ANCA specificity, significant association was observed in PR3-ANCA positive AAV (P = 0.0042, P c = 0.021, OR, 1.72; 95% CI, 1.19-2.49). In conclusion, ETS1 polymorphism was suggested to be associated with GPA and PR3-ANCA positive AAV in a Japanese population.

OBJECTIVE: Pulmonary infections (PI) are leading causes of death in patients with connective tissue diseases (CTD). The PREVENT study (Pulmonary infections in patients REceiving immunosuppressiVE treatmeNT for CTD) assessed risk of PI in patients with active CTD in the contemporary era of advanced immunosuppressive therapy. METHODS: In patients who started corticosteroids (n = 763), conventional immunosuppressants or biologics for active CTD were enrolled. Clinical and laboratory data, usage of drugs, and occurrence of PI were collected for 12 months. Baseline risk factors were investigated using Cox regression analysis. A nested case-control (NCC) study was performed with 1:2 matched case-control pairs to assess the risk for each drug category. RESULTS: During the observation period, 32 patients died (4.2%) and 66 patients were lost to followup (8.6%). Patients with PI (n = 61, 8%) had a significantly worse accumulated survival rate than patients without (p < 0.01). Cox hazard regression analysis using baseline data showed that these factors were significantly associated with PI: age ≥ 65 years (HR 3.87, 95% CI 2.22-6.74), ≥ 20 pack-years of smoking (2.63, 1.37-5.04), higher serum creatinine level (1.21, 1.05-1.41 per 1.0 mg/dl increase), and maximum prednisolone (PSL) dose during the first 2 weeks of treatment (2.81, 1.35-5.86 per 1.0 mg/kg/day increase). Logistic regression analysis by an NCC study revealed that maximum PSL dose within 14 days before PI (OR 4.82, 95% CI 1.36-17.01 per 1.0 mg/dl increase; 2.57, 1.28-5.16 if ≥ 0.5 mg/kg/day) was significantly associated with the events, while other immunosuppressants were not. CONCLUSION: Physicians should be aware of the higher risks for corticosteroids of PI than other immunosuppressants and assess these risk factors before immunosuppressive treatment, to prevent PI.

A 35-year-old woman was admitted to a hospital because of fever, sore throat, cervical lymph node swelling, and skin rashes. Laboratory data revealed leukocytosis and elevated C-reactive protein (CRP), aspartate aminotransferase, alanine aminotransferase, and ferritin levels. No antinuclear antibody or rheumatoid factor was found. She was diagnosed as having adult-onset Still's disease (AOSD). Although treatment with high-dose glucocorticoid (GC) and cyclosporine (CsA) was started, her condition did not improve because of complication with severe hemophagocytic syndrome (HPS). Therefore, she was transferred to our hospital. Immediately after admission, GC pulse therapy was started again, and treatment with CsA was replaced with tacrolimus (TAC), in addition, plasma exchange therapy was initiated. After treatment, her condition improved. However, 1 week after plasma exchange was discontinued, her condition deteriorated slightly with a slight fever and elevation of CRP level. This indicated that her condition could not be managed with GC and TAC, therefore, tocilizumab (TCZ) was added to her treatment, which improved her symptoms and enabled reduction in GC and TAC doses. Although many reports have indicated that biological agents are effective for refractory AOSD, their safety and efficacy in cases of AOSD complicated with HPS are controversial as these agents may exacerbate HPS. Our present case indicates that TCZ can be used after control of the disease activity by plasma exchange against refractory AOSD complicated with HPS.

OBJECTIVE: To investigate associations between continuous treatments with tumor necrosis factor (TNF) antagonists and risk for developing serious infections (SIs) over 3 years in Japanese patients with rheumatoid arthritis (RA) enrolled in the Registry of Japanese RA Patients for Long-Term Safety (REAL) database. METHODS: We analyzed 727 RA patients who had started either infliximab or etanercept (the anti-TNF group; 1,480.1 patient-years [PY]) and 571 RA patients who had started conventional nonbiologic disease-modifying antirheumatic drugs (the unexposed group; 1,104.1 PY) at the time of enrollment in the REAL. We assessed the occurrence of SIs within a 3-year observation period, including the period after switching to other TNF antagonists, and all SIs, unlimited to the first one in each patient as reported in other studies, to evaluate the real safety of TNF antagonists in daily practice. RESULTS: The incidence rate of SIs per 100 PY was 5.54 (95% confidence interval [95% CI] 4.44-6.84) in the anti-TNF group and 2.72 (95% CI 1.87-3.83) in the unexposed group. Poisson regression analysis revealed that the relative risk (RR) of continuous use of TNF antagonists for SIs after adjusting for baseline and time-dependent covariates was significantly elevated both overall (1.97, 95% CI 1.25-3.19) and for the first year (2.40, 95% CI 1.20-5.03), but not for the second and third years combined (1.38, 95% CI 0.80-2.43). The adjusted RR for SIs of etanercept compared to infliximab was not significantly elevated. CONCLUSION: Continuous anti-TNF therapy was significantly associated with increased risks for developing SIs during, but not after, the first year.

We describe 3 siblings who suffered from marked eosinophilia with organ involvement. One sibling, who experienced cervical lymphadenopathy and peripheral neuropathy with eosinophilia (5,834 cells/µL) following bronchial asthma, was diagnosed with Churg-Strauss syndrome (CSS) according to the criteria of the American College of Rheumatology. Another sibling, who suffered from severe asthma with persistent polyarthritis and eosinophilia (2,496 cells/µL), was also diagnosed with CSS according to the criteria of the Japanese Ministry of Health, Labour and Welfare. The remaining sibling, who had eosinophilic pleuritis with peripheral blood eosinophilia (699 cells/µL), did not fulfill the widely used criteria for CSS or hypereosinophilic syndrome (HES) ; however, he fit the newly proposed criteria for HES. Glucocorticoid treatment relieved their symptoms. Although the diagnoses and the criteria used for diagnosis differed between the siblings, all 3 patients showed common features such as eosinophilia with organ involvement that required treatment, indicating the possibility of familial eosinophilia (FE). Furthermore, the clinical features observed differed substantially from those of previously reported FE patients, therefore, these 3 siblings may be affected by a type of FE distinguishable from those previously described.

A 63-year-old man was admitted to our hospital because of persistent fever, weight loss, painful foot, and purpura on his extremities. He had lower extremity peripheral neuropathy, and skin biopsy of the purpura revealed vasculitis. Serum tests for myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA), proteinase 3-ANCA, and ANCA (indirect fluorescent antibody method) were all negative. Computed tomography revealed a 6-cm large, irregularly shaped lesion in the right kidney, while the nasal sinuses and lungs were intact. Based on these findings, a diagnosis of suspected systemic vasculitis associated with renal cell carcinoma was made. Thus, right nephrectomy was performed. However, the pathological findings showed a large infarct with necrotizing vasculitis of the arcuate, interlobular, and perinephric small arteries and a crescent formation in the glomerulus. Based on these findings, he was diagnosed with microscopic polyangiitis. Due to rapidly worsening symptoms of purpura and neuropathy, treatment with a high dose of corticosteroid was initiated on postoperative day 2, which led to improvement of his symptoms. Vasculitis accompanied with a mass-like lesion is occasionally confused with malignancy. The lesion in our patient was considered to have originated by asymptomatic renal infarction. This case suggests that a renal mass-like lesion with vasculitis should be diagnosed with care.
