This study finds that a single CD8 count has important prognostic significance in patients with advanced HIV infection and suggests that potential therapies to CD8 counts might be beneficial to patients with advanced HIV infection.
Statistical analysis that considered antiretroviral exposure, CD4 and CD8 counts, and a melange of classic risk factors determined that a current viral load above 50 copies/mL (versus below) independently raised the odds of a new MI 51% (adjusted odds ratio 1.51, 95% CI 1.09 to 2.10).
A double-blind placebo-controlled trial of multivitamins plus selenium in 400 HIV-infected nonpregnant Kenyan women found that supplementation significantly boosted CD4 and CD8 counts but--defying expectation--significantly increased vaginal shedding of HIV.
There was also a significant negative correlation for MIP1[beta] with lymphocyte per cent, lymphocyte count, CD4 per cent, CD4 count and CD8 count. There was a negative correlation between RANTES values and CD 8 per cent (Table III).
