- W171044359 abstract "Significant impairment of lung volumes and gas exchange in HIV-infected patients with acute Pneumocystis carinii pneumonia (PCP) has been reported, whereas little is known about lung function compromise following successful therapy. In 9 patients with acute PCP and 9 patients 1-5 month after PCP lung function testing including spirometry, diffusing capacity for carbon monoxide and exercise blood gas analysis were performed serially at monthly intervals. The results were summarized in a total score. The mean period of follow-up for each patient was 7.2 +/- 2 months. A decrease in lung volumes (FEV1 67 +/- 14.2% pred.norm., VC 72.7 +/- 11.9% pred.norm.) and gas exchange (CO-transfer factor 53.2 +/- 18.5% pred.norm., CO-transfer coefficient 67.8 +/- 14.2 pred. norm.) was observed in all 9 patients with acute PCP. Post-PCP lung volumes normalized within 1 month, whereas disorders in gas exchange persisted for 1-3 months. The total score normalized in 16/18 patients. One of the remaining patients with persisting functional impairment had chronic obstructive airway disease, whereas in the other dysfunction was even observed prior to PCP and no diagnosis could be obtained. 2-6 months following acute disease a second period of decreased lung function occurred in 6 pts. In 3 of the 6 there were no clinical signs of infection (rebronchoscopy refused), in 1 patient infection with cytomegalovirus was suspected. In the other 2 patients a relapse of PCP was diagnosed by bronchoscopy.Acute PCP compromises lung mechanics and gas exchange. During recovery deficits in gas exchange persist longer than diminished lung volumes.(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
