AIDS 2012: CD4 criteria improves the sensitivity of a clinical algorithm developed to identify viral failure in HIV-positive patients on first-line antiretroviral therapy

Abstract Background: Routine viral load monitoring of patients on antiretroviral therapy (ART) is neither affordable nor available in most resource-limited settings. We used data from an electronic patient management system to develop an algorithm to identify patients at risk of viral failure using a combination of accessible and inexpensive markers. Methods: We analyzed data from HIV-positive adults initiated on ART at Themba Lethu Clinic, South Africa between April 2004-February 2010. Viral 

AIDS 2012: The impact of antiretroviral therapy on quality of life and economic outcomes for South African patients: five-year follow-up

Abstract Background: The rapid expansion of antiretroviral therapy (ART) programs in resource-constrained countries in the previous decade has led to large numbers of patients reaching !5 years on ART, but little evidence exists about long-term economic outcomes. We report the effect of ART on symptoms, general health, ability to perform normal activities, and employment among patients in South Africa during the first five years on treatment. Methods: A cohort of 1065 adult South African 

AIDS 2012: Patient retention from HIV diagnosis through one year on antiretroviral therapy at a primary health clinic in Johannesburg, South Africa

Abstract: Background: A significant challenge to South Africa's national ART program is poor retention among HIV-positive patients. Studies investigating retention typically focus on post-ART retention, or isolated periods of pre-ART care (i.e. CD4 staging), but do not follow a cohort from testing through time on treatment to measure retention throughout early HIV care. We report patient retention at three stages of pre-ART care and two stages of post-ART care to identify when greatest 

The impact of antiretroviral therapy on quality of life and economic outcomes for South African patients: five-year follow-up

Abstract Background: The rapid expansion of antiretroviral therapy (ART) programs in resource-constrained countries in the previous decade has led to large numbers of patients reaching ≥5 years on ART, but little evidence exists about long-term economic outcomes. We report the effect of ART on symptoms, general health, ability to perform normal activities, and employment among patients in South Africa during the first five years on treatment. Methods: A cohort of 1065 adult South African

Incident pulmonary tuberculosis on antiretroviral therapy: seven years of experience at the Themba Lethu Clinic in Johannesburg, South Africa

Abstract Background: South Africa continues to have the largest HIV treatment program in the w orld alongside one of the w orld's largest tuberculosis (TB) epidemics. While antiretroviral therapy (ART) reduces the risk of acquiring TB for HIV-infected patients, rates of TB for those on ART remain high. After seven years of delivering HIV treatment, w e describe rates and predictors of incident TB over time in patients initiating ART at a large HIV clinic in South Africa. Methods: We
