Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Background:</title> <p>Suboptimal vitamin D status is prevalent in HIV-infected patients and associated with increased risk of disease severity and morbidity. We aimed to determine 12-month safety and efficacy of daily 7000 IU vitamin D<sub>3</sub> (vitD<sub>3</sub>) versus placebo to sustain increased serum 25-hydroxyvitamin D (25(OH)D) and improve immune status in HIV-infected subjects.</p> </sec> <sec> <title>Methods:</title> <p>This was a double-blind trial of perinatally acquired HIV (PHIV)-infected subjects or behaviorally acquired HIV (BHIV)-infected subjects (5.0-24.9 years). Safety, 25(OH)D-related parameters and immune status were assessed at baseline, 3, 6 and 12 months.</p> </sec> <sec> <title>Results:</title> <p>Fifty-eight subjects enrolled (67% male, 85% African American and 64% BHIV) and 50 completed with no safety concerns. In unadjusted analyses, there were no differences between randomization groups at baseline; at 3, 6 and 12 months, 25(OH)D was higher with supplementation than baseline and higher than with placebo (<italic>P</italic> < 0.05). In adjusted mixed models, in the supplementation group, the fixed effect of 25(OH)D was higher (<italic>P</italic> < 0.001). Percentage of naive T-helper cells (Th naive%) were significantly (<italic>P</italic> < 0.01) and T-helper cells (CD4%) marginally (<italic>P</italic> < 0.10) increased with supplementation in those taking highly active antiretroviral therapy (HAART), and RNA viral load was reduced (<italic>P</italic> ⩽ 0.05). In exploratory linear models, change in 25(OH)D predicted RNA viral load at 3 and 12 months and CD4% at 3 months (<italic>P</italic> < 0.05).</p> </sec> <sec> <title>Conclusions:</title> <p>Daily 7000 IU vitD<sub>3</sub> for 12 months was safe in HIV-infected subjects and effective in increasing 25(OH)D. Supplementation improved some clinically important HIV immune markers in subjects on HAART. Adjunct therapy with high-dose, daily vitD<sub>3</sub> for HIV-infected subjects and for those on/off HAART requires further investigation.</p> </sec> </abstract>
