Spectrum of opportunistic infections in hospitalized HIV-infected patients in Phnom Penh, Cambodia.

The aim of the study was to provide more comprehensive data on the clinical characteristics of hospitalized AIDS patients in Cambodia. Chart review of 381 HIV-infected patients admitted to a public hospital in Phnom Penh, Cambodia between December 1999 and May 2000 was performed. The in-hospital mortality rate was 43.6%. Approximately 50% of patients had two or more concurrent illnesses. Very advanced HIV disease was common, with CD4 cell counts below 10 cells/mm(3) in 43.2%. Only 28.3% of the patients had documentation of their HIV infection prior to hospitalization. Chronic diarrhoea was the most frequent opportunistic illness (41.2%), followed by tuberculosis (26%), cryptococcal meningitis (12.6%), Pneumocystis carinii pneumonia (8.4%), and encephalitis (4.7%). Chronic diarrhoea and tuberculosis were the most important opportunistic infections observed in HIV-infected hospitalized patients in Cambodia. These findings illustrate the need for early diagnosis of HIV-infection, effective prophylaxis for opportunistic infections and improved access to antiretroviral therapy in Cambodia.
