    The kidneys in people living with HIV (PLWH) are constantly exposed to highly antiretroviral therapy (HAART) which may cause renal dysfunction. Cystatin C (CystC), a biomarker of renal function, is well associated with renal impairment in various populations, however, it is underexplored in the South African population of PLWH, as compared to creatinine-based measurements. Creatinine-based measurements for assessing kidney function in people with HIV can be limited due to the influence of muscle wasting, altered creatinine metabolism, and the potential for certain antiretroviral medications to impact creatinine secretion. Therefore, the current study aimed to explore the effect of HAART on renal function among PLWH with the use of Cyst C-based measures. We conducted a cross-sectional study of 111 adults PLWH, 84 on HAART, and 27 on HAART-naïve. The cluster of differentiation 4 (CD4 +) count, plasma CystC, as well as the estimated glomerular filtration rate (eGFR) using the chronic kidney disease-epidemiology collaboration (CKD-EPI) formula, were determined. In the present study, no significant differences were observed between HAART-treated and HAART-naïve groups in terms of plasma CystC and eGFRCystC.

    Inter-individual genetic variation and the development of hypertension in a Xhosa African population of Eastern Cape, South Africa

    Cardiovascular diseases (CVD) are the leading cause of death globally, accounting for 18.6 million deaths. Hypertension (HTN) drives the global burden of CVD and is a leading cause of cardiovascular-related mortality with 1.4 billion affected adults and 10.4 million deaths globally. This public health condition has been escalating alarmingly in low and middle-income countries. In Sub-Saharan Africa, HTN is a major public health concern with South Africa having the highest prevalence between 27-58%. Accumulative evidence shows that HTN is driven by both modifiable and non-modifiable risk factors.
