<qa>  What is correlated with immune dysfunction in HIV-1 infected and uninfected individualsVitamin A deficiency leads to pathological changes in mucosal epithelium, including the vagina, and is correlated with immune dysfunction in both HIV-1 infected and uninfected individuals. Recent studies of genital tract shedding of HIV-1 DNA in infected women have found that lower serum concentrations of vitamin A were strongly associated with detection of HIV-1 in vaginal secretions. In addition, maternal vitamin A deficiency has been associated with significantly increased risk of vertical HIV-1 transmission. This study will assess the effect of vitamin A supplementation on the prevalence and quantity of HIV-1 DNA and RNA in cervical and vaginal secretions.
