Plasma lipidomic profiles and risk of diabetes: two prospective cohorts of HIV-infected and HIV-uninfected individuals

ObjectivesAntiretroviral therapy (ART) use is associated with disrupted lipid and glucose metabolism in people with HIV-infection. We aimed to identify plasma lipid species associated with risk of diabetes in the context of HIV infection.Research Design and MethodsWe profiled 211 plasma lipid species in 491 HIV-infected and 203 HIV-uninfected participants aged 35-55 years from the Women’s Interagency HIV study and the Multicenter AIDS Cohort Study. Cox proportional hazards model was used to examine associations between baseline lipid species and incident diabetes (166 diabetes cases were identified during a median follow-up of 12.6 years).ResultsWe identified 11 lipid species, representing independent signals for 8 lipid classes/subclasses, associated with risk of diabetes (PConclusionsThis study identified multiple plasma lipid species associated with incident diabetes. Regardless of the directions of their associations with diabetes, most diabetes-associated lipid species were elevated in ART-treated people with HIV-infection. This suggests a complex role of lipids in the link between ART and diabetes in HIV infection.
