High-dimensional analysis of T-cell profiling variations following belimumab treatment in systemic lupus erythematosus.

Objective: This study sought to elucidate the molecular impacts of belimumab (BEL) treatment on T-cell immune profiling in SLE.

Methods: We used mass cytometry with 25 marker panels for T-cell immune profiling in peripheral blood T cells (CD3+) from 22 patients with BEL-treated SLE and 20 controls with non-BEL-treated SLE. An unsupervised machine-learning clustering, FlowSOM, was used to identify 39 T-cell clusters (TCLs; TCL01-TCL39).

Efficacy of denosumab on bisphosphonate-treated osteoporosis and osteopenia in systemic rheumatic disease patients receiving glucocorticoids.

Introduction: Evidence on second-line agents for osteoporosis and osteopenia associated with glucocorticoid use after first-line bisphosphonate therapy is limited. We, therefore, examine the efficacy of denosumab on bisphosphonate-treated osteoporosis and osteopenia in Japanese systemic rheumatic disease (SRD) patients receiving glucocorticoids.

Materials And Methods: Glucocorticoid-treated SRD patients with a pre-existing fragility fracture, either lumbar spine (LS) or femoral neck (FN) bone mineral density (BMD) T-score of ≤ -2.

Baseline clinical features predicting macrophage activation syndrome in patients with systemic adult-onset Still's disease receiving interleukin-6 inhibitor treatment.

Aim: Macrophage activation syndrome (MAS), a severe complication of systemic adult-onset Still's disease (AOSD), has been reported to occur during interleukin-6 (IL-6) inhibitor treatment. However, predictors for MAS development are unknown. Therefore, this study investigated predictive features for MAS development after starting IL-6 inhibitor treatment in systemic AOSD patients.

Impact of dysphagia and its severity on long-term survival and swallowing function outcomes in patients with idiopathic inflammatory myopathies other than inclusion body myositis.

Objective: To investigate the impact of dysphagia on long-term survival and swallowing function outcomes in patients with idiopathic inflammatory myopathy other than inclusion body myositis.

Methods: We retrospectively evaluated consecutive patients with idiopathic inflammatory myopathy other than inclusion body myositis to investigate the impact of dysphagia and its severity assessed using the Food Intake LEVEL Scale on survival and swallowing function outcomes. Time-to-event analyses were used, including Kaplan-Meier curves with log-rank (trend) test, cumulative incidence with Gray's test, and Cox proportional hazards models.

Improvement of Chronic Rhinosinusitis and Reduction of the Myeloperoxidase-Antineutrophil Cytoplasmic Antibody Titer in a Patient with Eosinophilic Granulomatosis with Polyangiitis by Additional Mepolizumab.

A case of eosinophilic granulomatosis with polyangiitis (EGPA) in which chronic rhinosinusitis (CRS) was improved with a reduction in the myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) titer after the addition of mepolizumab is reported. A 55-year-old woman with EGPA receiving prednisolone 5 mg/day developed CRS with increases in the eosinophil count and the MPO-ANCA titer. Although it improved with prednisolone 15 mg/day in addition to mizoribine 150 mg/day, because azathioprine could not be taken orally due to side effects, it relapsed after prednisolone was tapered to 5 mg/day.

Circulating Th17.1 cells as candidate for the prediction of therapeutic response to abatacept in patients with rheumatoid arthritis: An exploratory research.

T-helper (Th)17.1 cells exhibit high pathogenicity in inflammatory diseases. This study aimed to identify the changes in the proportions of Th subsets, including Th17.

Effectiveness and safety of lower dose sulfamethoxazole/trimethoprim therapy for Pneumocystis jirovecii pneumonia in patients with systemic rheumatic diseases: A retrospective multicenter study.

Objectives: To evaluate the effectiveness and safety of lower-dose sulfamethoxazole/trimethoprim therapy (SMX/TMP) for Pneumocystis jirovecii pneumonia (PCP) in patients with systemic rheumatic diseases.

Methods: In this multicenter retrospective study, we compared effectiveness and safety of SMX/TMP for the treatment of PCP among patients divided into three groups according to the initial dosage of SMX/TMP: the low, ≤10 mg/kg/day; the intermediate, 10-15 mg/kg/day; and the high and conventional, 15-20 mg/kg/day for TMP dose.

Results: Eighty-one patients, including 22, 30, and 29 patients in the low-, the intermediate- and the high-dose group could be analyzed and the 30-day survival rate were 100%, 93.

Patient satisfaction and efficacy of switching from weekly bisphosphonates to monthly minodronate for treatment and prevention of glucocorticoid-induced osteoporosis in Japanese patients with systemic rheumatic diseases: a randomized, clinical trial.

Unlabelled: The randomized, clinical trial demonstrated that switching to monthly minodronate from weekly alendronate and risedronate provides greater increases in patients' satisfaction and bone mineral density and more substantial decreases in a bone resorption marker than continuing weekly alendronate and risedronate in patients with systemic rheumatic diseases on glucocorticoid therapy.

Purpose: Osteoporosis and associated fractures are major concerns for patients with systemic rheumatic diseases on long-term glucocorticoid therapy. Bisphosphonates increase bone mineral density (BMD) and reduce the frequency of vertebral fractures, but they are associated with poor adherence.
