One study from Italy demonstrated IFG was more common among HIV-infected, ART-naïve adults compared to HIV-negative controls [18], and the Multicenter AIDS Cohort Study in the USA showed that the prevalence and incidence of diabetes was higher among HIV-infected adults compared to controls [19,22], but the baseline CD4+ T-cell count was higher in both these groups of HIV-infected adults compared to our study. The gene discussed is CD4; the disease is diabetes mellitus.
