In resource-limited settings, high case-fatality rates are seen among tuberculosis (TB) patients with human immunodeficiency virus (HIV) infection, especially during the early months of TB treatment. HIV prevalence among TB patients has been estimated to be as high as 80%--90% in some areas of sub-Saharan Africa. In 2004, the World Health Organization (WHO) recommended increasing collaboration between HIV and TB programs. Since then, many countries, including Kenya, have worked to increase TB/HIV collaborative activities. In 2005, the Kenya Division of Leprosy, Tuberculosis, and Lung Disease (DLTLD) added questions regarding HIV testing and treatment to the existing TB surveillance system.* This report summarizes HIV data collected from Kenya's extended TB surveillance system during 2006--2009. During this period, HIV testing among TB patients increased from 60% in 2006 to 88% in 2009, and the prevalence of HIV infection among TB patients tested decreased from 52% to 44%. In 2009, 92% of HIV-infected TB patients received cotrimoxazole prophylaxis for the prevention of opportunistic infections. Although these data highlight the increase in HIV services provided to TB patients, only 34% of HIV-infected TB patients started antiretroviral therapy (ART) while being treated for TB. Innovative interventions are needed to increase HIV treatment among TB patients in Kenya, especially considering the 2009 WHO guidelines recommending that all HIV-infected TB patients be started on ART as soon as possible, regardless of CD4 count. Although these guidelines have not yet been implemented in Kenya, officials are working to identify methods of increasing access to ART for TB patients.
