• Hemophiliacs infected with human immunodeficiency virus with a history of hypersensitivity reaction to a combination product of trimethoprim and sulfamethoxazole were desensitized orally. Six of the seven patients included in the study successfully completed the desensitization protocol and received trimethoprim-sulfamethoxazole for 5 to 7 months after desensitization (mean length of treatment, 5.7 months) for prophylaxis of Pneumocystis carinii pneumonia. The small number of patients and the short follow-up allow us to suggest that oral desensitization may be an effective and inexpensive means to treat hemophiliacs infected with human immunodeficiency virus with trimethoprim-sulfamethoxazole as prophylaxis against Pneumocystis carinii pneumonia.
