Distinct Metabolic and Inflammation Signatures in Urban vs Rural Ugandan Youth With HIV on Dolutegravir.

BACKGROUND

In sub-Saharan Africa, the majority of the metabolic data are from youth living in urban areas. In youth with perinatally acquired HIV (YPHIV) and seronegative (HIV-), we examined inflammatory and metabolic signatures in urban versus rural Uganda.

METHODS

YPHIV (n = 100) were enrolled from urban and rural Uganda in an observational cohort study along with age- and sex- matched, population-based HIV- (n = 99) comparators. YPHIVs were on antiretroviral with HIV-1 RNA level ≤400 copies/mL. We compared variables using Wilcoxon rank-sum tests and chi-squared tests. General linear regression models were used to assess factors associated with metabolic and inflammatory biomarkers, adjusting for HIV status, socioeconomic factors, and other covariates.

RESULTS

Median age was 16.2 years, 52% rural versus 96% urban YPHIV had HIV-RNA <50 copies/mL, 93% of YPHIV were on Tenofovir, Lamivudine, and Dolutegravir. Overall, rural participants lived in extreme poverty compared to urban participants (P < .001). Urban YPHIV were more likely to have higher body mass index, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), total cholesterol, and low-density lipoprotein than rural YPHIV (P < .001); however sCD14, sCD163, high sensitivity C-reactive protein, interleukin-6, soluble tumor necrosis factor alspha receptor I (TNFRI), and lipopolysacchiride binding protein (LBP) were higher in rural YPHIV (P ≤ .001). After adjusting for demographic, socioeconomic, viral load and antiretroviral duration, only sCD14 remained elevated in the rural YPHIV (β: 1.1; 95% confidence interval, .2-2.0), and β D glucan in urban YPHIV (β 1.11; 95% confidence interval, .3-1.89).

CONCLUSIONS

The monocyte activation marker sCD14, was associated with HIV status and remained elevated in rural YPHIV even after adjusting for differences in HIV factors. Increasing the inclusion of rural populations in sub-Saharan Africa is paramount as we focus on preventing comorbidities in aging YPHIV.
