Real-life use of the PEXIVAS reduced-dose glucocorticoid regimen in granulomatosis with polyangiitis and microscopic polyangiitis.

Background: The PEXIVAS (Plasma exchange and glucocorticoids in severe antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis) trial showed that a reduced-dose glucocorticoid regimen (redGC) was non-inferior to a standard-dose regimen (standGC) with respect to death or end-stage kidney disease (ESKD) in patients with ANCA-associated vasculitis (AAV). However, the primary endpoint did not include disease progression or relapse, cyclophosphamide was the main induction therapy and rituximab (RTX)-treated patients tended to have a higher risk of death or ESKD with redGC. We aimed to evaluate the real-world use of redGC.

Convalescent Plasma Therapy in Immunocompromised Patients Infected With the BA.1 or BA.2 Omicron SARS-CoV-2.

The emergence of SARS-CoV-2 Omicron variant has led to a complete reconfiguration of the therapeutic landscape, with all monoclonal antibodies having lost any neutralization activity. We report here a case series of 75 immunocompromised patients infected by the Omicron variant who benefited from COVID-19 convalescent plasma (CCP). At Day 28, the overall survival was 76% (95% CI 67-86) with no significant difference in the clinical outcome between patients with hematological malignancies, solid organ transplantation or autoimmune diseases.
