Abstract
Advancing age is a risk factor for treatment-related side effects and mortality in AAV patients treated with cyclophosphamide (CYC) and glucocorticoids (GC) for remission induction. The efficacy and safety of rituximab (RTX) in elderly AAV patients has not been well described. We performed a single center retrospective review of 31 consecutive AAV patients aged 60 or more at the time of RTX use for remission induction. All patients received RTX with GC for remission induction. Four patients received concomitant CYC for a mean duration of 52 days. We evaluated clinical and laboratory variables at diagnosis, rates of complete remission defined as Birmingham Vasculitis Activity Score/Wegener's Granulomatosis (BVAS/WG) = 0 and patient survival, renal survival, infections requiring hospitalization, and vasculitis relapse 24 months following RTX use. Of the 31 patients, 77% were Caucasian, 68% female, mean age was 71 ± 6 years, 58% were MPO ANCA positive, and 42% had relapsing disease. The mean BVAS/WG score entry was 4.4 ± 1.5, 71% had glomerulonephritis (GN) and 10% had alveolar hemorrhage. The mean baseline e-GFR was 40 ± 28ml/min/1.73m(2). Thirty patients achieved remission with a mean time to remission of 57 ± 27 days. The singl...Continue Reading
