Rituximab versus azathioprine for maintenance of remission for patients with ANCA-associated vasculitis and relapsing disease: an international randomised controlled trial.

Objective: Following induction of remission with rituximab in anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) relapse rates are high, especially in patients with history of relapse. Relapses are associated with increased exposure to immunosuppressive medications, the accrual of damage and increased morbidity and mortality. The RITAZAREM trial compared the efficacy of repeat-dose rituximab to daily oral azathioprine for prevention of relapse in patients with relapsing AAV in whom remission was reinduced with rituximab.

Rituximab as therapy to induce remission after relapse in ANCA-associated vasculitis.

Objectives: Evaluation of rituximab and glucocorticoids as therapy to induce remission after relapse in ANCA-associated vasculitis (AAV) in a prospective observational cohort of patients enrolled into the induction phase of the RITAZAREM trial.

Methods: Patients relapsing with granulomatosis with polyangiitis or microscopic polyangiitis were prospectively enrolled and received remission-induction therapy with rituximab (4×375 mg/m) and a higher or lower dose glucocorticoid regimen, depending on physician choice: reducing from either 1 mg/kg/day or 0.5 mg/kg/day to 10 mg/day by 4 months.

Outcomes and compliance with standards of care in anti-neutrophil cytoplasmic antibody-associated vasculitis-insights from a large multiregion audit.

Objectives: We aimed to conduct a large audit of routine care for patients with ANCA-associated vasculitis.

Methods: We invited all 34 hospitals within one health region in England to undertake a retrospective case note audit of all patients newly diagnosed or treated with CYC or rituximab (RTX) for ANCA-associated vasculitis from April 2013 to December 2014. We compared clinical practice to the British Society for Rheumatology guidelines for the management of adults with ANCA-associated vasculitis and the use of RTX with the National Health Service (NHS) England commissioning policy and National Institute for Health and Care Excellence (NICE) technology appraisal.

Induction treatment of previously undiagnosed ANCA-associated vasculitis in a renal transplant patient with Rituximab.

We report the case of a 40-year-old female transplant patient with undiagnosed ANCA-associated vasculitis (AAV) and renal allograft dysfunction who achieved disease remission with restoration of transplant function following induction therapy with rituximab. There are currently no trial data looking at the use of rituximab for induction of remission of renal transplant patients with AAV. Although recurrence of AAV following renal transplantation is rare, such patients have invariably had multiple previous exposures to induction and maintenance immunosuppressive regimens, often limiting treatment options post-transplantation.
