Southern Africa is where almost 30 of the approximately 40 million HIV-infected people in the world live, in an area estimated to have 2 of the global population. While an estimated 2 million men, women, and children are yet in urgent need of antiretroviral treatment in this region, close to 200,000 individuals are now believed by the World Health Organization to be receiving treatment. Answers are urgently needed to clinical and operational research questions regarding the most effective implementation and monitoring of wide-scale antiretroviral treatment delivery.
Research Design and Methods:
The OASIS Collaboration includes 17 clinics and clinical cohorts in 6 countries in the region, involving 35,070 HIV-1 infected adults and children. We will use innovative and state-of-the-art statistical approaches to analyze data from this observational cohort study, including techniques which account for the longitudinal and hierarchical structure of the data. An operational structure is proposed that emphasizes the long-term collaborative and capacity-building approach of the collaboration.
INTRODUCTION: HIV care and treatment programmes worldwide are transforming as they push to deliver universal access to essential prevention, care and treatment services to persons living with HIV and their communities. The characteristics and capacity of these HIV programmes affect patient outcomes and quality of care. Despite the importance of ensuring optimal outcomes, few studies have addressed the capacity of HIV programmes to deliver comprehensive care. We sought to describe such capacity in HIV programmes in seven regions worldwide.
BACKGROUND: The risk of Kaposi sarcoma (KS) among HIV-infected persons on antiretroviral therapy (ART) is not well defined in resource-limited settings. We studied KS incidence rates and associated risk factors in children and adults on ART in Southern Africa.
OBJECTIVES: Many paediatric antiretroviral therapy (ART) programmes in Southern Africa rely on CD4⁺ to monitor ART. We assessed the benefit of replacing CD4⁺ by viral load monitoring.
DESIGN: A mathematical modelling study.

SETTING: Drug resistance threatens tuberculosis (TB) control, particularly among human immunodeficiency virus (HIV) infected persons.
OBJECTIVE: To describe practices in the prevention and management of drug-resistant TB under antiretroviral therapy (ART) programs in lower-income countries.
