Rituximab versus Cyclophosphamid in ANCA-associated renal Vasculitis

Cyclophosphamide induction regimens for antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis are effective in 70-90% of patients, but they are associated with high rates of death and adverse events. Treatment with rituximab has led to remission rates of 80 to 90% among patients with refractory ANCA-associated vasculitis and may be safer than cycliphosphamide regimens.

In the recent trials, the rate of composite outcome of death, end-stage renal disease and relapse did not differ between groups. In other word, rituximab-based regimen was not superior to standard intravenus cyclophosphamide for severe ANCA-associated vasculitis. Sustained-remission rates were high in both groups, and the rituximab-based regimen was not associated with reductions in early severe adverse events.
