[Severe Wegener's granulomatosis successfully treated with rituximab].

The paper discusses the problems of the diagnosis and treatment of Wegener's granulomatosis, the most common anti-neutrophil cytoplasmic antibody-associated systemic vasculitis. It describes a clinical case in which the administration of rituximab could achieve remission of severe Wegener's granulomatosis in a young man having numerous adverse reactions associated with the long-term use of high- and average-dose glucocorticoids and nonselective immunosuppressive agents. A place of rituximab in current drug therapy for Wegener's granulomatosis is shown.
