[Pneumocystis carinii infection during prophylaxis with nebulized pentamidine in a patient with AIDS]

Since the introduction of aerosolised pentamidine for prophylaxis against Pneumocystis carinii pneumonia (PCP) in HIV-seropositive persons and patients with AIDS, an increasing number of cases of atypical manifestations of infection with Pneumocystis carinii have been reported in the United States, viz. upper lobe pneumonia, extrapulmonary Pneumocystis carinii infection and spontaneous pneumothorax. An association between these atypical manifestations of Pneumocystis carinii infection and the use of aerosolised pentamidine seems likely. This report is the first description in the Netherlands of an atypical Pneumocystis carinii infection in an AIDS patient while using aerosolised pentamidine for prophylaxis against PCP. Since aerosolised pentamidine for prophylaxis against PCP is increasingly being used in the Netherlands, a rise in incidence of atypical manifestations of Pneumocystis carinii infection can be expected.
