Article Synopsis
- Rituximab (RTX) is a key treatment for various autoimmune and chronic inflammatory diseases but increases the risk of severe infections and lowers vaccine effectiveness due to its impact on B cell responses.
- During the COVID-19 pandemic, RTX-treated patients faced heightened disease severity, which led to delays or avoidance of RTX treatments to protect against SARS-CoV-2 infections.
- A study of thirteen patients showed that while some had positive T cell responses post-vaccination, those recently treated with RTX had significantly lower antibody responses, suggesting a need for caution in timing vaccinations relative to RTX infusions to optimize immune protection.
Combining drugs could be an effective option for treating multirefractory ITP, that is, patients not responding to rituximab, thrombopoietin receptor agonists (TPO-RA) and splenectomy. We conducted a retrospective, multicenter, observational study including multirefractory ITP patients who received a combination of a TPO-RA and an immunosuppressive drug. We included 39 patients (67% women, median age 59 years [range 21-96]), with a median ITP duration of 57 months [3-393] and a median platelet count at initiation of 10 × 10 /L [1-35].

Objective: To evaluate the efficacy of prolonged rituximab therapy in preventing AAV relapses in patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) who have achieved complete remission after completing an 18-month maintenance regimen.
Design: Randomized controlled trial.
Objective: The randomized, controlled MAINRITSAN2 trial was designed to compare the capacity of an individually tailored therapy [randomization day 0 (D0)], with reinfusion only when CD19+ lymphocytes or ANCA had reappeared, or if the latter's titre rose markedly, with that of five fixed-schedule 500-mg rituximab infusions [D0 + D14, then months (M) 6, 12 and 18] to maintain ANCA-associated vasculitis (AAV) remissions. Relapse rates did not differ at M28. This ancillary study was undertaken to evaluate the effect of omitting the D14 rituximab infusion on AAV relapse rates at M12.
