Intestinal Integrity Biomarkers in Early Antiretroviral-Treated Perinatally HIV-1-Infected Infants

Intestinal Integrity Biomarkers in Early Antiretroviral-Treated Perinatally HIV-1-Infected Infants Abstract Biomarkers of intestinal integrity (intestinal fatty acid binding protein (iFABP) and zonulin), were compared in early antiretroviral-treated, HIV-1-infected (HIV+; n=56) African infants and HIV-exposed but uninfected (HEU; n=53) controls. Despite heightened inflammation and immune activation in HIV+ infants, iFABP and zonulin levels at three months of age were not different from those in HEU infants, and largely not correlated with inflammatory and immune activation biomarkers. However, zonulin levels increased, and became significantly higher in HIV+ compared to HEU infants by five months of age despite ART-suppression. These findings have implications for intestinal integrity biomarker profiling in perinatal HIV-1 infection. perinatal HIV-1 infection, intestinal integrity, inflammation, immune activation, zonulin, intestinal fatty acid binding protein © The Author(s) 2018.

Abstract

Abstract Biomarkers of intestinal integrity (intestinal fatty acid binding protein (iFABP) and zonulin), were compared in early antiretroviral-treated, HIV-1-infected (HIV+; n=56) African infants and HIV-exposed but uninfected (HEU; n=53) controls. Despite heightened inflammation and immune activation in HIV+ infants, iFABP and zonulin levels at three months of age were not different from those in HEU infants, and largely not correlated with inflammatory and immune activation biomarkers. However, zonulin levels increased, and became significantly higher in HIV+ compared to HEU infants by five months of age despite ART-suppression. These findings have implications for intestinal integrity biomarker profiling in perinatal HIV-1 infection. perinatal HIV-1 infection, intestinal integrity, inflammation, immune activation, zonulin, intestinal fatty acid binding protein © The Author(s) 2018.
