Rituximab for the treatment of Churg-Strauss syndrome with renal involvement.

ABSTRACT:

Introduction

Churg-Strauss syndrome (CSS) is a small vessel systemic vasculitis associated with asthma and eosinophilia that causes glomerulonephritis (GN) in ∼25% of patients. Rituximab (RTX) is a chimeric anti-CD20 monoclonal antibody that depletes B cells and is effective in numerous autoimmune diseases including antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. We aim to evaluate the safety and efficacy of RTX in inducing remission of renal disease activity in patients with CSS.

Methods

We conducted a single-center, open-label pilot study using RTX (375 mg/m(2)/week × 4) for induction of remission in CSS patients with renal involvement [defined as having >25% dysmorphic red cells, red blood cell casts or pauci-immune GN on biopsy]. Written informed consen
