Effectiveness and safety of low-energy shock wave therapy for digital ulcers associated with systemic sclerosis: a phase 3 pivotal clinical trial.

Objectives: Systemic sclerosis is characterised by ischaemic skin ulcers on the fingertips, and low-energy shock wave therapy is suggested as a novel treatment for ischaemic lesions with angiogenic effects. We aimed to investigate the efficacy and safety of shock wave therapy for skin ulcers in patients with systemic sclerosis.

Methods: In this phase 3 pivotal study, we analysed 60 systemic sclerosis patients with digital ulcers that did not disappear after >4 weeks of existing treatment: 30 patients were treated with extracorporeal shock wave therapy and 30 with conventional treatment.

Associations of disease duration and anti-citrullinated peptide antibody status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis: Post hoc analysis of a multicentre, real-world observational study in Japan (ORIGAMI).

Objectives: The aim of the article is to investigate the associations of disease duration and anti-cyclic citrullinated peptide antibody (ACPA) status with the effectiveness of abatacept in biologic-naïve patients with rheumatoid arthritis (RA).

Methods: We performed post hoc analyses of the Orencia® Registry in Geographically Assembled Multicenter Investigation (ORIGAMI) study of biologic-naïve RA patients aged ≥20 years with moderate disease activity who were prescribed abatacept. Changes in the Simplified Disease Activity Index (SDAI) and Japanese Health Assessment Questionnaire (J-HAQ) at 4, 24, and 52 weeks of treatment were analysed in patients divided according to ACPA serostatus (positive/negative), disease duration (<1/≥1 year), or both.

Investigation of treatment continuity, usefulness, and nocebo effect in switching from the original etanercept to its biosimilar in patients with rheumatoid arthritis: A JET observational study in Japanese clinical practice.

Objectives: To assess the usefulness and onset of nocebo effects after switching from the original etanercept (ETN) to a biosimilar (BS) in routine clinical practice at rheumatology clinics in Japan (13 sites).

Methods: A total of 165 patients (87.0% women, age = 57.

Importance of tenosynovitis in preventing the progression through rheumatoid arthritis continuum.

Rheumatoid arthritis (RA) has long been characterized by synovitis and bone erosions typically developing symmetrically in small joints. However, recent advances in imaging modalities have indicated frequent association of tenosynovitis with RA, and some consider tenosynovitis to be not just a complication but a major trait of RA. Furthermore, as there are cases with tenosynovitis preceding the clinical detection of inflammatory arthritis in predisposed individuals, tenosynovitis may constitute an important biomarker in defining the pre-RA phase of disease development.

Rheumatoid arthritis patients with low baseline Health Assessment Questionnaire scores have a risk of functional disability progression: a post hoc analysis of a nationwide longitudinal cohort in Japan.

Objectives: To determine prognostic factors for the Health Assessment Questionnaire-Disability Index (HAQ-DI) progression in patients with rheumatoid arthritis (RA) in clinical practice.

Methods: We evaluated 388 biological disease-modifying anti-rheumatic drug (bDMARD)-naïve Japanese patients with RA with moderate to high disease activity at study entry after being treated with conventional synthetic DMARDs. These patients were treated according to a treat-to-target (T2T) strategy for one year.

Anti-citrullinated peptide antibodies are the strongest predictor of clinically relevant radiographic progression in rheumatoid arthritis patients achieving remission or low disease activity: A post hoc analysis of a nationwide cohort in Japan.

Objectives: To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) achieving remission or low disease activity (LDA) in clinical practice.

Methods: Using data from a nationwide, multicenter, prospective study in Japan, we evaluated 198 biological disease-modifying antirheumatic drug (bDMARD)-naïve RA patients who were in remission or had LDA at study entry after being treated with conventional synthetic DMARDs (csDMARDs). CRRP was defined as the yearly progression of modified total Sharp score (mTSS) >3.

Maintenance treatment using abatacept with dose reduction after achievement of low disease activity in patients with rheumatoid arthritis (MATADOR) - A prospective, multicenter, single arm pilot clinical trial.

Objectives: To preliminarily evaluate the feasibility of maintenance therapy with reduced dose of intravenous abatacept (ABT) to 250 mg/body/month after achieving remission or low disease activity (LDA).

Patients And Methods: RA patients treated with ABT at 13 sites were enrolled in this prospective interventional pilot study during the period between March 2013 and March 2015. Inclusion criteria were (1) age at 20 years or older, (2) under treatment with monthly intravenous ABT at approved doses, (3) DAS28-CRP lower than 2.

Prognostic Factors Toward Clinically Relevant Radiographic Progression in Patients With Rheumatoid Arthritis in Clinical Practice: A Japanese Multicenter, Prospective Longitudinal Cohort Study for Achieving a Treat-to-Target Strategy.

To determine prognostic factors of clinically relevant radiographic progression (CRRP) in patients with rheumatoid arthritis (RA) in clinical practice.We performed a multicenter prospective study in Japan of biological disease-modifying antirheumatic drug (bDMARD)-naive RA patients with moderate to high disease activity treated with conventional synthetic DMARDs (csDMARDs) at study entry. We longitudinally observed 408 patients for 1 year and assessed disease activity every 3 months.

Prevalence of hepatitis B virus infection in patients with rheumatic diseases in Tohoku area: a retrospective multicenter survey.

Hepatitis B virus (HBV) reactivation has been increasingly recognized in patients receiving chemotherapy and immunosuppressive therapy; however, the prevalence of HBV infection and rate of HBV screening in patients with rheumatic diseases remains unclear. In this study, we aimed to assess the prevalence of HBV infection and fulminant HBV hepatitis in patients with rheumatic diseases. We also investigated the rate of HBV screening before immunosuppressive therapy in patients with rheumatic diseases.

[Analysis of human cytomegalovirus infection of an autopsy case of dermatomyositis with rapidly progressive interstitial pneumonia: the possible correlation between the viral genome and its related protein on the pathogenesis].

We describe a case of a 61-year-old woman with amyopathic dermatomyositis (ADM), who developed rapidly progressive interstitial pneumonia and died of respiratory failure. An autopsy revealed interstitial pneumonia with diffuse alveolar damage, associated with infiltration of T cells, mostly positive for CD 8. The alveolar lining epithelial cells manifested the remarkable expression of immediate early/early antigen of human cytomegalovirus (HCMV).
