CD4 and AIDS: The association of log10CRP(C-reactive protein) were inversely correlated with CD4 lymphocyte counts (r = -0.17, p < 0.001) and directly with log10HIV RNA levels (r = 0.20, p < 0.001). Levels of CRP of > 2.3 mg/l were associated with decreased time to AIDS (acquired immunodeficiency syndrome).
