Chronic Cough in Patients with HIV Infection

Abstract

We retrospectively studied the clinical spectrum, course and outcome of 26 patients with HIV infection and chronic cough. All except 2 were homo-/bisexual males. 22 (85%) had AIDS. They had cough for a mean of 75 d with sputum production (88%) and dyspnoea (77%) being the commonest associated symptoms. Sputum examination and chest X-ray were useful initial investigations. CT scan of the chest and sinuses had a high rate of abnormal results for selected patients (89-100%). Cause of cough was found in 21 patients (81%): bronchopulmonary infections (17), Kaposi's sarcoma 5 and sinus infections 3. Patients with sinopulmonary infections tended to have longer duration of cough. Overall, 4 patients (15%) had significant improvement in the illness with cough during the study period. Four patients with bronchopulmonary infections died. We concluded that chronic cough is a heterogeneous clinical problem in advanced HIV-infected patients, most commonly caused by an infective process. Extrapulmonary disease, such as sinusitis, has to be considered and investigated. The clinical course and outcome is unfavourable for most of the patients.
