Sulfamethoxazole-trimethoprim may be an alternative or adjunctive treatment for Wegener's granulomatosis, as suggested by our experience with six patients. Two had limited Wegener's granulomatosis; one of these achieved remission with sulfamethoxazole-trimethoprim alone, and the second achieved remission with sulfamethoxazole-trimethoprim and prednisone. Four patients presented with sinus, pulmonary, and renal involvement. One patient initially treated with sulfamethoxazoletrimethoprim developed worsening renal function requiring cytotoxic therapy. Two patients initially treated with cytotoxic agents achieved remission coincident with the addition of sulfamethoxazole-trimethoprim for persistent sinus symptoms. One patient had relapse of pulmonary symptoms after achieving and maintaining a remission during treatment with sulfamethoxazole-trimethoprim alone. This experience suggests that sulfamethoxazole-trimethoprim may be an effective treatment for some patients with Wegener's granulomatosis and may be the only agent required. Patients require careful follow-up and still may need cytotoxic therapy.
