Pulmonary Manifestations in HIV Seropositive Patients and Their Correlation with CD4 Counts in a Tertiary Care Centre of North India.

ABSTRACT

The prolonged course of human immunodeficiency virus (HIV) infection is marked by a decrease in the number of circulating CD4+ T helper cells and persistent viral replication, resulting in immunologic decline and death from opportunistic infections. The study was conducted in HIV Seropositive Patients admitted in our hospital. Demographic profile of the patient was recorded along with history, examination, investigations and evaluated for pulmonary manifestations and correlated with the CD4 counts. Age of HIV positive cases ranged from 21 to 74 years, male female ratio was 31. Commonest mode of transmission was heterosexual sex (77%) followed by IV drug abusers (13.3%). Commonest X- ray finding was Infiltrates (33.3%) followed by pleural effusion (8%) and miliary mottling (5.3%). Commonest pulmonary diagnosis was pulmonary tuberculosis in 22.6% cases, followed by pyogenic pneumonia in 14.67% and pneumocystis carinii pneumonia (PCP) in 5.3% cases. Extrapulmonary tuberculosis was present in 16% of the cases. Pulmonary tuberculosis and pyogenic pneumonia was present in over wide range of CD4 count but their incidence has increased as the CD4 count declined. The knowledge of the CD4 count level in HIV patients is extremely useful in making differential diagnosis and suggesting a diagnostic and therapeutic plan.
