Subjects in this cohort had severe immunosuppression. The prevalence of pathogens, including Cryptosporidium, was extremely high but did not differ significantly between the case patients with diarrhea and the control subjects without diarrhea. Further studies are needed to examine factors associated with Cryptosporidium carriage and the natural history of asymptomatic infection.
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.
The HIV epidemic in Cambodia is one of the most extensive in Asia. Meningitis accounts for a substantial proportion of HIV-related morbidity and mortality in Cambodia. A retrospective chart review was performed to identify the clinical and spinal fluid characteristics of patients undergoing spinal tap at an AIDS referral hospital in Phnom Penh, Cambodia during a 16-month period. Of 932 charts reviewed, 89 met criteria for analysis. Overall mortality was 49.4%. Cryptococcus was the most commonly identified pathogen (83%), followed by mycobacteria (8%). No pathogen was identified in 9% of charts reviewed. In hospital mortality was similar in all groups.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
