We have measured the fatty acid (FA) composition of erythrocyte membra
nes and plasma anti-oxidants in HIV + patients. Saturated FA are highe
r and poly-unsaturated FA lower than in controls (P = 0.02). Selenium
(Se) is lower in patients less than 400 CD4 cells/mm(3) (P = 0.002). V
itamin A is lower in the HIV + regardless of the CD4 cell count. Se an
d vitamin A are correlated to nutritional markers (body mass index and
albumin).
