To determine prognostic factors for the Health Assessment Questionnaire-Disability Index (HAQ-DI) progression in patients with rheumatoid arthritis (RA) in clinical practice.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. The Disease Activity Score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR) and the HAQ-DI were assessed every three months. We also evaluated joint destruction using a modified total Sharp score at baseline and at one year. HAQ-DI progression was defined as the yearly progression of HAQ-DI >0.1. We performed a multiple logistic regression analysis to explore the factors predicting HAQ-DI progression at one year.HAQ-DI progression was observed in 18% of the patients. The multiple logistic regression analysis revealed the independent variables associated with HAQ-DI progression were: DAS28-ESR >5.1 at baseline (odds ratio [OR] 0.31, 95% con dence interval [CI] 0.13-0.74, p=0.0083); HAQ-DI score at baseline <0.5 (OR 2.27, 95% CI 1.22-4.26, p=0.0102); and achievement of low disease activity at 12 weeks (OR 0.42, 95% CI 0.21-0.82, p=0.0112).Our data suggest that maintaining clinical improvement according to T2T and initiating the treatment at an early stage are important for functional improvement after one year and that patients with low baseline HAQ scores have a higher risk of HAQ disability progression.
To investigate whether human T lymphotropic virus type I (HTLV-I) directly infects salivary gland epithelial cells (SGECs) and induces the niche of the salivary glands in patients with Sjögren's syndrome (SS).SGECs were cultured with the HTLV-I-producing CD4+ T cell line HCT-5 or with Jurkat cells. Antibody arrays, immunofluorescence analysis, and enzyme-linked immunosorbent assay (ELISA) were used to determine the profiles of inflammation-related molecules, and the profiles of apoptosis-related molecules were determined by antibody array and immunofluorescence analysis. The presence of HTLV-I-related molecules was assessed by immunofluorescence analysis and in situ polymerase chain reaction. Apoptosis of SGECs was evaluated by TUNEL staining.Among the SGECs, 7.8 ± 1.3% (mean ± SD) were positive for HTLV-I-related proteins after 96-hour coculture with HCT-5 cells. Nuclear NF-κB p65 was also detected in 10% of the SGECs. The presence of HTLV-I proviral DNA in SGECs after coculture with HCT-5 cells was detected by in situ polymerase chain reaction. After coculture of SGECs with HCT-5, the expression of cytokines and chemokines, including soluble intercellular adhesion molecule 1, RANTES, and interferon γ-induced protein 10 kd (IP-10/CXCL10) was increased in a time-dependent manner. The expression of proapoptotic molecules (e.g., cytochrome c and Fas) and antiapoptotic molecules (e.g., Bcl-2, Heme oxygenase 2, and Hsp27) was increased in the SGECs cocultured with HCT-5, showing that apoptosis of SGECs was not detected after coculture with HCT-5 or Jurkat cells.HTLV-I is thought to infect SGECs and alter their cellular functions. These changes may induce the niche of SS and contribute to the development of SS in anti-HTLV-I antibody-positive individuals.
This study clarifies the involvement of gender and pre-existing diabetes mellitus (DM) in the clinical characteristics of polymyalgia rheumatica (PMR).The clinical records of patients diagnosed with PMR in our department between January 2011 and June 2021, especially in terms of gender and DM were retrospectively analysed.We identified 89 patients with the median age of 75.37 cases were men and 52 cases were women. Pre-existing DM was found in 21 patients (23.6%). Male PMR patients exhibited a higher complication rate of pre-existing DM and C-reactive protein (CRP) levels at diagnosis (p = .04 and p < .01, respectively) than female patients, and men were more common in the patient group with pre-existing DM (p = .04). The CRP levels of male PMR patients without pre-existing DM were higher than female PMR patients without pre-existing DM.Male PMR patients might have a varying pathophysiology from female patients in terms of high inflammation levels accompanied by a high prevalence rate of pre-existing DM and need a gender-specific approach.
Objective. We have tried to clarify the clinical importance of the measurement of serum type-I interferon (IFN) in patients with anti-melanoma differentiation-associated gene 5 Ab (MDA5 Ab)-positive dermatomyositis (DM). Methods. We studied 30 patients with DM: 10 were anti-MDA5 Ab-positive and 20 were anti-MDA5 Ab-negative. At each patient's initial visit, serum IFN-α, IFN-β, interleukin 18 (IL-18), ferritin, and the titer of anti-MDA5 Ab were measured using enzyme-linked immunosorbent assays (ELISAs). The associations between the IFNs and with the other variables were examined. Results. Rapidly progressive interstitial lung disease (RPILD) was confirmed in 10 patients, most of whom were complicated in the anti-MDA5 Ab-positive DM patients. The presence of clinically amyopathic dermatomyositis (CADM) as well as the serum concentrations of IFN-α and ferritin was significantly higher in the anti-MDA5 Ab-positive DM patients. Serum concentration of IL-18 did not differ between anti-MDA5 Ab-positive and anti-MDA5 Ab-negative groups; however, a positive correlation was found between IFN-α and IL-18 in the anti-MDA5 Ab-positive DM patients (r = 0.8139, p = 0.0146). Conclusion. Serum IFN-α can be used as a useful biomarker in patients with anti-MDA5 Ab-positive DM, which may reflect the presence of RPILD.
Objective: To clarify the efficacy and safety of abatacept for secondary Sjögren’s syndrome (SS) associated with rheumatoid arthritis (RA). Methods: The primary endpoint of this open-labeled, prospective, observational multicenter study for secondary SS with RA was the remission rate of Simplified Disease Activity Index (SDAI) at 52 weeks after initiation of abatacept. The secondary endpoints included Saxon’s test and Schirmer’s test. Adverse events and adherence rate during the study period were also analyzed. Results: Thirty-six patients (all females) were enrolled in this study. The mean SDAI decreased significantly from 20.6 ± 11.2 (±SD) at baseline to 10.0 ± 10.5 at 52 weeks (p < 0.05). Patients with SDAI remission increased from 0 (0 week) to 12 patients (33.3%) at 52 weeks. Saliva volume assessed by Saxon’s test increased significantly from 2136 ± 1809 (0 week) to 2397 ± 1878 (24 weeks) mg/2 min (n = 34, p < 0.05). Saliva volume increased significantly from 2945 ± 2090 (0 week) to 3419 ± 2121 (24 weeks) mg/2 min in 11 patients with Greenspan grade 1 or 2 of labial salivary gland biopsy (p < 0.05), but no change was noted in 18 patients with Greenspan grade 3 or 4. Tear volume by Schirmer’s test increased significantly from 4.2 ± 4.8 (0 week) to 6.4 ± 7.8 (24 weeks) mm/5 min (n = 30, p < 0.05). The adherence rate to abatacept was 80.6% (29/36) over the 52-week period. Twelve adverse events occurred in 10 of the 36 patients, and 7 of these events were infections. Conclusion: Abatacept seems to be effective for both RA and SS related manifestations.
