Clinical characteristics and natural history of human immunodeficiency virus infected patients seen at a general hospital in Singapore.
The number of patients with human immunodeficiency virus (HIV) infection in Singapore has risen over the years. A considerable proportion of them present with acquired immunodeficiency syndrome (AIDS). In this study, we document the clinical characteristics and natural history of a consecutive series of 50 patients who were found to have HIV infection when they were seen at a tertiary care hospital. The majority were in the 30 to 49 age group and the most common mode of acquisition was heterosexual contact. The patients presented with a variety of symptoms to 11 different clinical departments. Fifty-eight per cent of the patients had AIDS-defining illnesses at presentation, with Pneumocystis carinii pneumonia being the most common. On follow-up, the most frequently occurring opportunistic infection that developed was Cytomegalovirus retinitis. Most patients had multiple subsequent admissions--for both AIDS-defining and non AIDS-defining conditions. The median CD4 count of the cohort at presentation was 72/mm3. The median survival was 399 and 822 days in those who had and those who did not have an AIDS-defining illness at presentation, respectively. Mortality was most commonly attributed to pneumonia. HIV infection has protean manifestations and patients may present to various specialty departments; hence, doctors need to be aware of the spectrum of disease in order to make a diagnosis.
