[Pulmonary diseases in patients with HIV infection].
OBJECTIVE
To characterize the spectrum, incidence rate and features of pulmonary pathology in HIV-infected inpatients with reference to a fall in the count of CD4-lymphocytes.


METHODS
A total of 2370 patients with HIV infection admitted to Moscow infectious hospital N 2 were examined. The protocol of examination included: standard diagnostic tests, bronchoscopy with examination of bronchoalveolar lavage and bronchial biopsies for genetic markers of basic pulmonary disease pathogens, assessment of external respiration function by spirometry. By the count of CD4-lymphocytes in the blood (> 500 cells/mcl; 500-200 cells/mcl and < 200 cells/mcl) the patients with pulmonary pathology were divided into groups 1, 2 and 3.


RESULTS
Affection of the lower respiratory tract (LRT) was detected in 1209 (51%) patients. Incidence, etiological spectrum and severity of LRT lesions increased significantly with aggravation of immunological disorders. The patients of group 1 were affected more frequently with bacterial bronchitis, pneumonia (88.2%), group 2 patients - with bacterial pneumonia (67.1%) and pulmonary tuberculosis (28.1%), group 3 - with tuberculosis including generalized forms (53.9%), cytomegalovirus infection (11.2%), pneumocystosis (7.2%). Combined pulmonary pathology was diagnosed in 25% cases.


CONCLUSIONS
Changes in external respiration function were most evident in pneumocystosis and tuberculosis, but they were most persistent in cytomegaloviral lesion of the lungs. Some tuberculosis and CMV infection patients exhibited ventilatory disorders prior to clinical and x-ray symptoms, this suggests prognostic significance of spirometry.
