Incidence of cardiometabolic diseases in a Lesotho HIV cohort: Evidence for policy decision-making.

BACKGROUND

Antiretroviral treatment (ART) has been associated with the development of certain cardiometabolic diseases (CMDs). The burden of CMDs amongst ART-experienced patients in sub-Saharan Africa was unknown.

OBJECTIVE

We quantified the burden of CMDs and identified the associated risk factors in a large treatment cohort on ART at a high-volume facility in Lesotho.

METHODS

In this retrospective cohort study, we extracted data from the daily dispensing electronic system and routine clinical records of 785 adults on ART between 2011 and 2015 in Maseru, Lesotho. CMD was defined as a diagnosis of hypertension, diabetes mellitus or dyslipidaemia (singly or collectively). Descriptive statistics were used to describe the disease burden; Kaplan-Meier curves and cause-specific Cox proportional hazards models were fitted to examine the impact of the ART regimen and identify the risk factors associated with the occurrence of CMD.

RESULTS

Of the 785 participants, 473 (60%) were women. The median age of the group was 42 years, interquartile range (IQR), 36-51 years. The overall incidence of CMD was 5.6 (95% confidence interval [CI] = 4.4-7.1) per 100 person-months of follow-up. The median time to onset of CMD was 16.6 months (IQR = 7.4-23.4). ART was not associated with the occurrence of CMD (cause-specific hazard ratio [CHR] = 1.55; 95% CI = 0.14-16.85;

CONCLUSION

The incidence of CMD in this relatively young patient population is low yet noteworthy. We recommend that patients living with HIV and AIDS should be routinely screened for CMD. Higher BMI is generally associated with the occurrence of CMD.
