Abstract

Abstract Background Selenium deficiency has been reported to be associated with HIV disease progression and chromium deficiency with insulin resistance and hyperlipidemia. Here, we assessed selenium and chromium status in a cohort of Ugandan HIV+, HIV exposed uninfected (HEU) and HIV negative (HIV−) children and their associations with markers of systemic inflammation, immune activation, and gut integrity. Methods This is a cross-sectional study in HIV+, HEU and HIV unexposed uninfected (HIV-) children aged 2–10 years old enrolled in Uganda. HIV+ children were on stable ART with undetectable viral load. We measured plasma concentrations of selenium and chromium as well as markers of systemic inflammation, monocyte activation, gut integrity and insulin resistance (HOMA-IR). Results Among HIV+ children (n = 57), 93% had viral load ≤ 20 copies/mL, mean CD4 was 34% and 77% were receiving a non-nucleotide reserve transcriptase regimen. Mean age of all participants was 7 years and 55% were girls. Mean selenium concentrations were higher in the HIV+ group (106 µg/L) compared with the HEU (84 µg/L) and HIV− (98 µg/L) groups (p . Mean chromium concentrations were 1 µg/L; 1 HIV+ child and 6 HEU children had chromium levels > 1 µg/L (p. Conclusion In this cohort of HIV+ children on ART in Uganda, plasma selenium and chromium concentrations appear sufficient. Higher plasma selenium concentrations were associated with lower systemic inflammation and higher gut integrity markers. Although our findings do not support the use of selenium supplementation broadly for HIV-infected children in Uganda, further studies are warranted to assess the role of selenium supplements in attenuating heightened inflammation.
