Vitamin D is not associated with HIV-associated neurocognitive disorder in Rakai, Uganda

We investigated whether vitamin D is associated with HIV-associated neurocognitive disorder (HAND). HIV-infected (HIV+) antiretroviral therapy (ART)-naïve adults in rural Uganda underwent a neurocognitive battery for determination of HAND stage at baseline and after 2 years. Baseline serum 25-hydroxyvitamin D (25OH-D) and serum and cerebrospinal fluids (CSF) vitamin D-binding protein (VDBP) were obtained. Of the 399 participants, 4% (n = 16) were vitamin D deficient (25OH-D < 20 ng/mL). There was no association between 25OH-D, serum or CSF VDBP, and HAND stage at baseline or follow-up. Future studies in a population with higher levels of vitamin D deficiency may be warranted.
