Serum levels of vitamins A and E Non-concurrent prospective study in 341 men. vitamin E levels (23.5 μmol/l) Decrease in risk of progression to AIDS - Tang et al. [159]
Antioxidant vitamins (A,C,E) supplementation
 
Measurement of levels of oxidatively-modified DNA bases in lymphocytes of sero-positive patients & controls. Asymptomatic HIV-infected patients (n is 30), as well as in control groups (10 healthy volunteers and 15 HIV-sero-negative injected drug users). Significant decrease in the levels of all modified DNA bases; decreased antioxidant enzyme activities 6 months. Jaruga et al. [54]
Daily supplements of vitamin A, multivitamins (vitamins B, C, and E). 1078 pregnant women infected with HIV in a double-blind, placebo-controlled trial. Human Significantly higher CD4+ and CD8+ cell counts and significantly lower viral loads. Multivitamin supplements delay the progression of HIV disease and provide an effective Over a two-year period Fawzi et al. [211]
