To compare the efficacy and safety of dapsone versus atovaquone in preventing or delaying the onset of histologically proven or probable Pneumocystis carinii pneumonia in HIV-infected patients with CD4 counts <= 200 cells/mm3 or <= 15 percent of the total lymphocyte count who are intolerant to trimethoprim and/or sulfonamides.
Trimethoprim/sulfamethoxazole (TMP/SMX), which is effective for secondary PCP prophylaxis, is associated with allergic manifestations and side effects that limit its use. Patients who are intolerant of TMP/SMX require an effective alternative. Dapsone and atovaquone have both shown promise as PCP prophylactic agents.

Official Title: | A Randomized, Comparative Study of Daily Dapsone and Daily Atovaquone for Prophylaxis Against PCP in HIV-Infected Patients Who Are Intolerant of Trimethoprim and/or Sulfonamides |
Estimated Enrollment: | 700 |
Trimethoprim/sulfamethoxazole (TMP/SMX), which is effective for secondary PCP prophylaxis, is associated with allergic manifestations and side effects that limit its use. Patients who are intolerant of TMP/SMX require an effective alternative. Dapsone and atovaquone have both shown promise as PCP prophylactic agents.
Patients are randomized to receive either dapsone or atovaquone daily, with follow-up at the clinic every 4 months.
