BACKGROUND Although effective antiretroviral therapy(ART) increases CD4+ T-cell count, responses to ART vary considerably and only a minority of patients normalise their CD4+/CD8+ ratio. Although retention of naïve CD4+ T-cells is thought to predict better immune responses, relationships between CD4+ and CD8+ T-cell subsets and CD4+/CD8+ ratio have not been(More)
BACKGROUND Increasing numbers of HIV-infected patients in sub-Saharan Africa are exposed to antiretroviral therapy (ART), but there are few data on lipid changes on first-line ART, and even fewer on second-line. METHODS DART was a randomized trial comparing monitoring strategies in Ugandan/Zimbabwean adults initiating first-line ART and switching to(More)
BACKGROUND Reference intervals are used as an aid in the interpretation of laboratory results. Most developing countries do not have reference intervals specific to adolescents. This study was aimed at establishing hematological and biochemical reference intervals for adolescents aged ≥ 12 years to < 18 years. METHODS A community based, cross sectional(More)
OBJECTIVE Although low bone mineral density (BMD) is prevalent in HIV, changes in BMD over time remain unclear. We aimed to compare rates of, and factors associated with, BMD change between HIV-positive and HIV-negative patients. METHODS In a prospective, 3-year cohort, HIV-positive and HIV-negative patients provided annual demographic and clinical data,(More)
BACKGROUND Omega-3 long chain-polyunsaturated fatty acids (LC-PUFAs)-docosahexaenoic acid (DHA), docosapentaenoic acid (DPA) and eicosapentaenoic acid (EPA)- and omega-6 LC-PUFA arachidonic acid (ARA), are essential for optimum physical and mental development in children. Prior to this study, the blood omega-3 LC-PUFA levels were unknown in Zimbabwean(More)
OBJECTIVES Although current guidelines recommend resistance testing prior to antiretroviral therapy (ART) reinitiation after treatment interruptions, virological failure of first-line ritonavir-boosted, protease-inhibitor (PI/r)-containing ART is associated with low emergent PI resistance. In patients experiencing unscheduled treatment interruptions (UTrIs)(More)
BACKGROUND The HIV Care Cascade model can be used to measure how clinical services align with United Nations' (UN) HIV treatment targets. Previous models have highlighted sequential losses at each step of the Cascade with a significant proportion being not retained in care (NRIC). OBJECTIVE We aimed to assess the feasibility of meeting the UN targets and(More)
BACKGROUND Laboratory reference ranges used for clinical care and clinical trials in various laboratories in Zimbabwe were derived from textbooks and research studies conducted more than ten years ago. Periodic verification of these ranges is essential to track changes over time. The purpose of this study was to establish hematology and chemistry laboratory(More)
