OBJECTIVES: The intensification of infliximab (IFX) treatment, involving escalation of the dose and shortening of interval, was approved in Japan in July 2009. We consider IFX intensification therapy to be preferable for patients with treatment-resistant active rheumatoid arthritis (RA). We retrospectively compared the efficacy of IFX with that of other bDMARDs in methotrexate (MTX)-resistant patients. METHODS: Patients who satisfied the following criteria were enrolled: (i) those who started bDMARDs between February 2011 and December 2016, and (ii) those who required bDMARDs after 180 d of MTX treatment...

OBJECTIVES: Suppressor of TCR signaling-2 (STS-2) is one of the RA susceptibility genes identified in genome-wide association studies (GWAS). We tried to verify the involvement of STS-2 on the development of autoimmune arthritis in a mouse model. METHODS: STS-2 knock-out (KO) and wild type (WT) mice were immunized with chicken type II collagen (CII). For CD4(+) helper T cell (Th) subset analysis, intracellular cytokines in splenocytes and lymph node cells were stained and analyzed by flow cytometry...

OBJECTIVES: We aimed to investigate alpha beta double negative (αβ DN) T-cell percentages in juvenile systemic lupus erythematosus (JSLE) and their relation to disease activity and organ involvement. METHODS: This prospective study was carried out over a period of 12 months and included 21 JSLE patients and 20 healthy matched controls. SLE disease activity index 2000 (SLEDAI-2K) scores were recorded in addition to αβ DN T-cell percentages measurement at enrollment and after remission...

OBJECTIVES: To evaluate usage patterns for methotrexate (MTX) and/or glucocorticoids in rheumatoid arthritis (RA) patients receiving biological disease-modifying antirheumatic drugs (bDMARDs) in daily practice. METHODS: Data from RA patients who commenced treatment with bDMARDs (infliximab [IFX], etanercept [ETN], tocilizumab [TCZ], or adalimumab [ADA]) from 2008 to 2010 were extracted from the Institute of Rheumatology, Rheumatoid Arthritis (IORRA) database. The proportions of patients taking concomitant MTX and glucocorticoids and doses of these medications were evaluated before and 2 years after initiation of each bDMARD...

BACKGROUND: Treat to target (T2T), aiming at inactive disease (ID), has become the recommended strategy for axial-SpA (ax-SpA). Using the Ankylosing Spondylitis Disease Activity Score (ASDAS), we assessed the prevalence of ID in ax-SpA patients treated with TNFα inhibitors (TNFi). METHODS: A multicentric, cross-sectional study was performed assessing disease activity status (BASDAI and ASDAS) of consecutive patients with ax-SpA on stable treatment with TNFi for at least six months...

OBJECTIVES: We aimed to identify the relationship between achievement of a physical activity goal and the characteristics of patients with rheumatoid arthritis (RA). METHODS: Overall, 137 patients with RA who performed physical activity were enrolled. Statistical analysis was performed to examine relationship between patient characteristics and achievement of physical activity goal by univariate analysis, multivariate logistic regression analysis and the receiver operating characteristic method...

OBJECTIVE: The aims of this study are to determine the incidence of CHB in the Japanese population and to identify maternal factors predicting fetal congenital heart block (CHB) in anti-Ro/SSA antibody positive pregnancy. METHODS: A retrospective study was performed using 52,147 clinical records of pregnancies followed in a single center. For 183 anti-Ro/SSA antibody-positive women, anti-Ro52 and Ro60 antibodies were measured, and the odds of CHB in relation to maternal clinical features were calculated by multivariate analysis...

OBJECTIVES: To determine the tentative diagnostic criteria and disease severity classification for Castleman disease (CD) and describe the clinical and pathologic features among human herpesvirus 8 (HHV-8) negative idiopathic multicentric CD (iMCD) in the Japanese population. METHODS: We established the working groups for the research of CD in Japan and had meetings to discuss and define the tentative diagnostic criteria and disease severity classification for CD...

OBJECTIVES: The purpose of this study was to facilitate the understanding of the SAPHO (Synovitis, Acne, Pustulosis, Hyperostosis, and Osteitis) syndrome by analyzing the clinical and radiological features of 67 Japanese patients with SAPHO syndrome. METHODS: Sixty-seven Japanese patients (female/male: 44/23, mean age at onset: 48.5 years) were diagnosed with SAPHO syndrome from 2002 to 2013 at our hospital. Medical records and radiological imaging of these patients were retrospectively reviewed...

OBJECTIVES: We aimed to evaluate the association between the change in serum IL-6 during the clinical course of tocilizumab (TCZ) therapy and rheumatoid arthritis (RA) disease activity or occurrence of adverse events. METHODS: General laboratory data including serum IL-6 levels and physical findings were obtained every 4 weeks, and, in addition, at the time when any adverse events occurred. RESULTS: The proportion achieving Clinical Disease Activity Index (CDAI) remission at 52 weeks was significantly lower in 20 patients with serum IL-6 ≥ 30 pg/ml at 12 weeks than 24 patients with serum IL-6 < 30 pg/ml...

OBJECTIVE: To search for signs and symptoms before serious infection (SI) occurs in tocilizumab (TCZ)-treated rheumatoid arthritis (RA) patients. METHODS: Individual case safety reports, including structured (age, sex, adverse event [AE]) and unstructured (clinical narratives) data, were analyzed by automated text mining from a Japanese post-marketing AE-reporting database (16 April 2008-10 April 2015) assuming the following: treated in Japan; TCZ RA treatment; ≥1 SI; unable to exclude causality between TCZ and SIs...

OBJECTIVE: Monosodium urate (MSU) has been shown to promote interleukin-1β (IL-1β) secretion in human monocytes, but the priming signals for NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome pathway remains elusive. In this study, we investigated the role of Tumor necrosis factor-alpha (TNF-α) on MSU-mediated IL-1β induction in human neutrophils. METHODS: Human neutrophils were stimulated with MSU, in the presence or absence of TNF-α priming...

Rheumatoid arthritis (RA) is a chronic inflammatory disorder characterized by progressive joint destruction. Recent studies have indicated the critical involvement of osteoclasts in bone destruction in RA. The osteoclast differentiation factor receptor activator of NF-κB ligand (RANKL), which belongs to the tumor necrosis factor-α superfamily, plays a critical role in osteoclast differentiation and bone destruction in RA. Denosumab, an antibody against human RANKL, efficiently suppressed the progression of bone erosion in RA patients in a randomized controlled study, and is considered as a putative therapeutic option for preventing bone destruction in RA...

OBJECTIVE: Neutrophil extracellular traps (NETs) are peculiar structures composed of the externalized chromatin with intracellular proteins and formed by activated neutrophils in a reactive oxygen species (ROS)-dependent manner. Aberrant NETs are considered to be autoantigens for anti-neutrophil cytoplasmic antibodies (ANCAs) underling the development of microscopic polyangiitis (MPA). However, little is known regarding the therapeutic efficacy of in vivo inhibition of NET formation (NETosis) on MPA pathogenesis...

OBJECTIVE: The objective of this study was (1) to determine productivity costs due to absenteeism and presenteeism among Japanese workers with rheumatoid arthritis (RA), and (2) to identify additional factors associated with productivity loss among workers with RA. METHODS: An online survey of 500 RA Japanese patients was used. The Japanese version of the Stanford Health Assessment Questionnaire (J-HAQ) was used to measure patients' functional disability. The patient health questionnaire-9 item (PHQ-9) was used to measure symptoms and severity of depression...
