ABSTRACT

SETTING: Cambodia has the highest human immunodeficiency virus (HIV) prevalence (1.9%) and tuberculosis (TB) incidence (508/100000) in Asia. Banteay Meanchey, a province with high HIV prevalence of 1.9%, established a pilot project in 2003 to enhance TB-HIV activities. We evaluated this project to improve performance. METHODS: In March 2005, we analyzed 17 months of data on all persons diagnosed with HIV or TB at 11 participating clinics. We determined barriers to HIV testing and TB screening, modified the program to reduce these barriers and assessed whether our interventions improved testing and screening rates. RESULTS: Among 952 patients newly diagnosed with TB disease, 138 (14%) had known HIV infection at the time of TB diagnosis. Of the 814 TB patients with unknown HIV status, 432 (53%) were HIV tested. Of 1228 persons newly diagnosed with HIV infection, 450 (37%) were screened for TB disease. We found and addressed barriers to HIV testing and TB screening. In the 9 months after the interventions, 240/322 (71%) TB patients were HIV tested, an increase of 34% (P < 0.01); 426/751 (57%) HIV-infected patients were screened for TB, an increase of 54% (P < 0.01). CONCLUSION: Evaluations of TB-HIV collaborative activities can lead to increased TB screening and HIV testing rates.

ABSTRACT

SETTING: Banteay Meanchey Province, Cambodia. OBJECTIVE: The World Health Organization recommends human immunodeficiency virus (HIV) testing for all tuberculosis (TB) patients and TB screening for all HIV-infected persons in countries with a TB-HIV syndemic. We sought to determine whether evidence supports implementing these recommendations in South-East Asia. DESIGN: We conducted a cross-sectional survey and retrospective cohort study of patients newly diagnosed with HIV or TB from October 2003 to February 2005 to identify risk factors for HIV infection and TB, and for death during TB treatment. RESULTS: HIV infection was diagnosed in 216/574 (38%) TB patients. TB disease was found in 124/450 (24%) HIV-infected persons. No sub-groups of patients had a low risk of HIV infection or TB. Of 180 TB patients with HIV infection and a recorded treatment outcome, 49 (27%) died compared to 17/357 (5%) without HIV infection (relative risk [RR] 5.2, 95% confidence interval [CI] 3.1-8.7). HIV-infected TB patients with smear-negative pulmonary disease died less frequently than those with smear-positive pulmonary disease (RR 0.39, 95%CI 0.16-0.93). CONCLUSIONS: No sub-groups of patients had low risk for HIV infection or TB, and mortality among HIV-infected TB patients was high. These data justify using the WHO global TB-HIV recommendations in South-East Asia. Urgent interventions are needed to reduce the high mortality rate in HIV-infected TB patients.
