Lowest ever CD4 lymphocyte count (CD4 nadir) as a predictor of current cognitive and neurological status in human immunodeficiency virus type 1 infection--The Hawaii Aging with HIV Cohort.
Low CD4 lymphocyte count was a marker for neurological disease in human immunodeficiency virus type 1 (HIV-1); but is now less common among patients with access to highly active antiretroviral therapy. In this study, the authors determine the reliability of self-reported CD4 nadir and its predictive value for neurological status. The authors identify a high degree of reliability (r = .90). After adjusting for age, current CD4 count, and duration of HIV-1, CD4 nadir relates to a current diagnosis of HIV-associated dimentia (HAD) (odds ratio [OR]: 1.395 (1.106-1.761), P = .005) and distal symmetric polyneuropathy (DSPN) (OR: 1.479 (1.221-1.769, P < .001).
