Interventional study on Dolutegravir and other antiretrovirals in patients with subclinical atherosclerosis in the Kinshasa Hospital

IntroductionAfter 2016, the World Health Organization (WHO) proposed Dolutegravir (DTG) as an alternative first-line treatment for adults. Thus, the purpose of this study was to identify biomarkers of cardiometabolic risk capable of demonstrating the beneficial effect of Dolutegravir (DTG) compared to other antiretrovirals in predicting atherosclerosis in people living with HIV (PLHIV) and hospitalized in Kinshasa Hospital. Methodswe conducted an interventional study of people living with HIV who had received antiretroviral therapy (ART) for at least 6 months and were treated in the structures of the network coordinated by the Catholic Church (BDOM-Bureau Diocésain des Oeuvres Médicales) and of the University Clinics of Kinshasa (CUK) between January 2017 and December 2021. Subclinical atherosclerosis was defined as Pulsed Pressure (PP) ≥60 mm Hg; Carotid Intima-Media Thickness (CIMT) > 0.8 mm; and Systolic Pressure Index (SPI) < 0.9. Logistic regression was used in the statistical analysis of associations. Resultsa total of 334 PLHIV were recruited, of whom 96.1% (n=321) were on ART and 13.9% (n=13) were ART naïve patients. The mean age of PLHIV was 51±12 years with a female predominance (70.4%; n=235); the independent determinants of subclinical atherosclerosis were marital status (aOR: 4. 95% CI 1.5-10.5; p
