Abstract

Although prophylaxis has led to a decline in the frequency of P. carinii pneumonia among HIV-infected patients, the mortality associated with PCP ranges from 10% to 30%. We studied 11 patients infected by HIV without AIDS. Subjects underwent chest X-ray, blood gas sampling, pulse oximetry before and during exercise, and induced sputum examination for P. carinii. The subjects were divided in 2 groups based on SO 2 behavior during exercise. Oxygen desaturation during exercise was observed in 15 (37%) of the subjects (group 1), and 11 (73%) of them had P. carinii detected in induced sputum. In 26 subjects (63%) oxygen desaturation did not occur during exercise and P. carinii was absent in all. We concluded that oxygen saturation during exercise may be a sensitive method for prediction of subclinical lung diseases by P. carinii in asymptomatic HIV-infected subjects.
