Changes over time in creatinine clearance and comparison of emergent adverse events for HIV-positive adults receiving standard doses (300 mg/day) of lamivudine-containing antiretroviral therapy with baseline creatinine clearance of 30-49 vs ≥50 mL/min.

A retrospective analysis of the randomized controlled DART (Development of AntiRetroviral Therapy in Africa; ISRCTN13968779) trial in HIV-1-positive adults initiating antiretroviral therapy with co-formulated zidovudine/lamivudine plus either tenofovir, abacavir, or nevirapine was conducted to evaluate the safety of initiating standard lamivudine dosing in patients with impaired creatinine clearance (CLcr). Safety data collected through 96 weeks were analyzed after stratification by baseline CLcr (estimated using Cockcroft-Gault) of 30-49 mL/min (n = 168) versus ≥50 mL/min (n = 3,132) and treatment regimen. The Grade 3-4 adverse events (AEs) and serious AEs (for hematological, hepatic and gastrointestinal events), maximal toxicities for liver enzymes, serum creatinine and bilirubin and maximum treatment-emergent hematology toxicities were comparable for groups with baseline CLcr 30-49 versus CLcr≥50 mL/min.

Pretreatment HIV drug resistance results in virological failure and accumulation of additional resistance mutations in Ugandan children.

Background: Pretreatment HIV drug resistance (PDR) can impair virological response to ART, jeopardizing effective treatment for children.

Methods: Children aged ≤12 years initiated first-line ART in Uganda during 2010-11. Baseline and 6 monthly viral load (VL) and genotypic resistance testing if VL >1000 copies/mL was done.

Affordable HIV drug-resistance testing for monitoring of antiretroviral therapy in sub-Saharan Africa.

Increased provision of antiretroviral therapy in sub-Saharan Africa has led to a growing number of patients with therapy failure and acquired drug-resistant HIV, driving the demand for more costly further lines of antiretroviral therapy. In conjunction with accelerated access to viral load monitoring, feasible and affordable technologies to detect drug-resistant HIV could help maximise the durability and rational use of available drug regimens. Potential low-cost technologies include in-house Sanger and next-generation sequencing in centralised laboratories, and point mutation assays and genotype-free systems that predict response to antiretroviral therapy at point-of-care.

Second-line HIV Treatment in Ugandan Children: Favorable Outcomes and No Protease Inhibitor Resistance.

Background: Data on pediatric second-line antiretroviral treatment (ART) outcomes are scarce, but essential to evaluate second-line and design third-line regimens.

Methods: Children ≤12 years switching to second-line ART containing a protease inhibitor (PI) in Uganda were followed for 24 months. Viral load (VL) was determined at switch to second-line and every 6 months thereafter; genotypic resistance testing was done if VL ≥ 1000 cps/ml.

Identification of gaps for implementation science in the HIV prevention, care and treatment cascade; a qualitative study in 19 districts in Uganda.

Background: 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.

HIV Drug Resistance Among Children Initiating First-Line Antiretroviral Treatment in Uganda.

Background: There are limited data on primary human immunodeficiency virus drug resistance (HIVDR) in pediatric populations. This study aimed to assess the prevalence of primary HIVDR and associated risk factors among children initiating first-line antiretroviral therapy (ART) in Uganda.

Methods: At three Ugandan clinics, children (age <12 years) requiring ART were recruited between January 2010 and August 2011.

Using Exclusion-Based Sample Preparation (ESP) to Reduce Viral Load Assay Cost.

Viral load (VL) measurements are critical to the proper management of HIV in developing countries. However, access to VL assays is limited by the high cost and complexity of existing assays. While there is a need for low cost VL assays, performance must not be compromised.

Clinical differences between younger and older adults with HIV/AIDS starting antiretroviral therapy in Uganda and Zimbabwe: a secondary analysis of the DART trial.

Objective: Clinical and immunological data about HIV in older adults from low and middle income countries is scarce. We aimed to describe differences between younger and older adults with HIV starting antiretroviral therapy in two low-income African countries.

Setting: HIV clinics in Uganda and Zimbabwe.

Determinants of clinician knowledge on aging and HIV/AIDS: a survey of practitioners and policy makers in Kampala District, Uganda.

Objective: The HIV/AIDS epidemic has evolved with an increasing burden in older adults. We assessed for knowledge about aging and HIV/AIDS, among clinicians in Kampala district, Uganda.

Methods: A cross-sectional survey of 301 clinicians complemented by 9 key-informant interviews between May and October 2011.

Genotype assays and third-line ART in resource-limited settings: a simulation and cost-effectiveness analysis of a planned clinical trial.

Objectives: To project the clinical and economic outcomes of a genotype assay for selection of third-line antiretroviral therapy (ART) in resource-limited settings, as per the planned international A5288 trial (MULTI-OCTAVE).

Methods: We used the Cost-effectiveness of Preventing AIDS Complications (CEPAC)-International Model to compare three strategies for patients who have failed second-line ART in South Africa: sustained second-line: no genotype assay, all patients remain on second-line ART; A5288: genotype to determine the resistance profile and assign an appropriate regimen; or population-based third-line: no genotype, all patients switch to a potent third-line regimen. Model inputs are from published data in South Africa.

HIV vaccines: the Uganda experience.

By late 1980s Uganda was the epicenter of the AIDS epidemic in the world but strong preventive interventions and committed leadership has turned the epidemic round. HIV incidence and prevalence have declined but infection rates remain unacceptably high, making HIV vaccine research a priority. Uganda pioneered the first HIV vaccine trial in Africa but had to overcome ethical, scientific and logistical challenges.
