title: Aerosolized pentamidine: a well-tolerated mode of prophylaxis against Pneumocystis carinii pneumonia in older children with human immunodeficiency virus infection.
abstract: Aerosolized pentamidine has been recommended as an alternative mode of antipneumocystis prophylaxis in human immunodeficiency virus-infected children with trimethoprim-sulfamethoxazole intolerance. However, there have been no definitive data concerning the most appropriate dose and the tolerance of aerosolized pentamidine in children. In the present study, we assessed the tolerance of aerosolized pentamidine in older children using a regimen similar to the one recommended in adults. A 300-mg dose of pentamidine was administered to our human immunodeficiency virus-infected patients monthly using the Respirgard II nebulizer. Patients were assessed for their heart rate, respiratory rate, breath sounds and oxygen saturations during and after pentamidine aerosolization. During a 21-month period (August, 1989, to May, 1991), 22 patients (mean age, 9.8 +/- 0.6 years; range, 3 to 15 years) received a total of 185 treatments. Patients complained of either a bitter taste (16 of 22) or developed short periods of coughing (15 of 22) during the aerosol. Five patients developed reversible bronchospasm requiring bronchodilators; no patients developed oxygen desaturation. None of the patients developed Pneumocystis carinii pneumonia during the limited protocol follow-up (mean, 9.8 months). Thus aerosolized pentamidine for antipneumocystis prophylaxis is well-tolerated in older children. However, more comprehensive investigations of efficacy are indicated.
