[Pneumocystis carinii pneumonia in HIV-positive and HIV-negative patients].

: Bronchoalveolar lavage was used in 170 immunocompromised patients for detection of causative agents. Pneumocystis carinii was isolated 18 times from HIV-positive patients and 14 times from patients suffering from immunodeficiencies due to various other diseases. Patients with AIDS were in better clinical condition, had fewer infiltrates on chest x-ray, a higher oxygen partial pressure and lower LDH-plasma concentration than HIV-negative patients. In spite of the earlier stage of the disease patients with AIDS experience prodromal symptoms for a longer time and the number of isolated pneumocystis was larger. Mortality in AIDS patients was significantly lower than in patients with other causes of immunodeficiency.
