BACKGROUND The efficacy and toxic effects of nucleoside reverse-transcriptase inhibitors (NRTIs) are uncertain when these agents are used with a protease inhibitor in second-line therapy for human immunodeficiency virus (HIV) infection in resource-limited settings. Removing the NRTIs or replacing them with raltegravir may provide a benefit. METHODS In(More)
BACKGROUND In sub-Saharan Africa antiretroviral therapy (ART) is being decentralized from tertiary/secondary care facilities to primary care. The Lablite project supports effective decentralization in 3 countries. It began with a cross-sectional survey to describe HIV and ART services. METHODS 81 purposively sampled health facilities in Malawi, Uganda and(More)
BACKGROUND WHO 2013 guidelines recommend universal treatment for HIV-infected children younger than 5 years. No paediatric trials have compared nucleoside reverse-transcriptase inhibitors (NRTIs) in first-line antiretroviral therapy (ART) in Africa, where most HIV-infected children live. We aimed to compare stavudine, zidovudine, or abacavir as dual or(More)
From 2006 to 2011, a cohort study was conducted among 1000 children resident in urban and rural settings of Uganda to ascertain and compare the response to antiretroviral therapy (ART) among urban versus rural children and the factors associated with this response. Clinical, immunological, and virological parameters were ascertained at baseline and weeks(More)
BACKGROUND Few studies have investigated objective markers of lipodystrophy in African children. We compared body circumferences, skin-fold thickness (SFT) and lipids in antiretroviral therapy (ART)-naive and stavudine (d4T)-exposed children with HIV-uninfected controls. METHODS In the CHAPAS-3 trial, HIV-infected children (ART-naive or on d4T for ≥2(More)
BACKGROUND Decentralization of ART services scaled up significantly with the country wide roll out of option B plus in Uganda. Little work has been undertaken to examine population level access to HIV care particularly in hard to reach areas in rural Africa. Most work on ART scale up has been done at health facility level which omits people not accessing(More)
Over the last 20 years, countries in sub Saharan Africa have made significant strides in the implementation of programs for HIV prevention, care and treatment. Despite, the significant progress made, many targets set by the United Nations have not been met. There remains a large gap between the ideal and what has been achieved. There are several operational(More)
BACKGROUND Lifelong antiretroviral therapy (ART) for pregnant and breastfeeding women (Option B+) was rolled out in Zimbabwe from 2014, with simultaneous raising of the CD4 treatment threshold to 500 cells per cubic millimeter in nonpregnant/breastfeeding adults and children 5 years and over. METHODS Lablite is an implementation project in Zimbabwe,(More)
BACKGROUND Cross-resistance after first-line antiretroviral therapy (ART) failure is expected to impair activity of nucleoside reverse-transcriptase inhibitors (NRTIs) in second-line therapy for patients with HIV, but evidence for the effect of cross-resistance on virological outcomes is limited. We aimed to assess the association between the activity,(More)
