DETECTION OF PNEUMOCYSTIS-CARINII, MYCOBACTERIUM-TUBERCULOSIS, AND CYTOMEGALOVIRUS IN HUMAN-IMMUNODEFICIENCY-VIRUS (HIV)-INFECTED PATIENTS WITH HEMOPHILIA BY POLYMERASE CHAIN-REACTION OF INDUCED SPUTUM SAMPLES

The purpose of this study was to diagnose the initial stage of acute pulmonary infections due to Pneumocystis carinii (P. carinii), Mycobacterium tuberculosis (M. tuberculosis), and cytomegalovirus (CMV) by polymerase chain reaction (PCR) combined with the induced sputum method in hemophilia patients infected with human immunodeficiency virus (HIV). Induced sputum and PCR were obtained at each outpatient visit or when any respiratory symptoms were present during a one-year period. All patients with a CD4+ count of less than 200x10(6)/l were given prophylactics against P. carinii pneumonia (PCP), PCR was conducted 111 times in 29 patients, M. tuberculosis DNA was detected in 1 patient and CMV DNA in 4 patients, P. carinii DNA was not detected, PCR on induced sputum samples is sensitive for the rapid detection of the initial stage of respiratory events. PCP prophylaxis changes the clinical manifestations of HIV infection.
