Successful Pneumocystis carinii pneumonia prophylaxis using aerosolized pentamidine in children with acute leukemia.
1994
PURPOSEWe report our experience replacing trimethoprim-sulfamethoxazole (TMP/SMX) with aerosolized pentamidine (AP) in 22 children with acute leukemia who could not tolerate TMP/SMX.PATIENTS AND METHODSChildren (age 1 to 15 years) with acute leukemia during maintenance chemotherapy or post-bone marrow transplantation (BMT) receiving prophylaxis for Pneumocystis carinii pneumonia (PCP) with TMP/SMX received AP following prolonged neutropenia or allergy to TMP/SMX. Patients received 300 mg of AP monthly (children < 4 years received 150 mg) dissolved in 5 mL of distilled water over 20 to 30 minutes.RESULTSOver a 3-year period, 358 courses of AP were administered over 10,124 observable days. AP was adequately tolerated on a monthly basis for prophylaxis against PCP in 22 children with acute leukemia. AP was demonstrated to be effective in preventing PCP. There were minimal side effects observed during this trial. The majority of children with acute lymphoblastic leukemia (ALL; 12 of 14 [86%]) undergoing maint...
