Glucocorticoid tapering pace in microscopic polyangiitis and granulomatosis with polyangiitis in Japanese real-world practice: A propensity score-matched retrospective cohort study from the J-CANVAS registry.

Objective: To assess the prevalence and outcomes among regimens of glucocorticoid tapering for microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) in real-world practice.

Methods: We retrospectively examined the Japan Collaborative Registry of ANCA-associated Vasculitis (J-CANVAS) registry, and evaluated the prevalence of glucocorticoid tapering regimens in the PEXIVAS trial. In patients with newly diagnosed MPA and GPA, we compared outcomes among standard and reduced pace regimens.

Identification of circulating microbial DNA and its association with kidney function in patients with diabetic kidney disease.

Aim: Recently, substantial studies have been accumulated to indicate the important role of gut microbiota in diabetic kidney disease (DKD). The abnormal change of bacterial-derived products could imply specific injuries or play beneficial or harmful roles in DKD progression. In this study, we examined the presence and contribution of the Klebsiella oxytoca gene in the circulation of patients with DKD.

Roxadustat for Treating Anemia in Patients with Advanced Chronic Kidney Disease Not Undergoing Dialysis: A Retrospective Study.

Objective Roxadustat, a hypoxia-inducible factor-prolyl hydroxylase inhibitor, increases the hemoglobin (Hb) levels in patients with chronic kidney disease (CKD). To date, limited clinical studies have focused on the excessive increase in the Hb levels in the early weeks after switching from erythropoiesis-stimulating agents (ESA) to roxadustat in adult non-dialysis patients. We conducted a retrospective study to examine whether early overshoot frequently occurs after switching to roxadustat.

Effectiveness and safety of rituximab in severely relapsed antineutrophil cytoplasmic antibody-associated vasculitis: a retrospective analysis of a Japanese multicentre cohort from the J-CANVAS.

We aimed to clarify the long-term safety and efficacy of rituximab (RTX) as a remission induction therapy following severe relapse in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). We retrospectively collected the data of patients with severely relapsed AAV from a Japanese multicentre cohort. The primary exposure was RTX use; the primary outcome was complete remission (CR) proportions at week 24.
