Depressive Symptoms and CD4 Lymphocyte Decline Among HIV-Infected Men

Abstract

Overall depression and affective depression predicted a more rapid decline in CD4 lymphocyte counts; this association was not attributable to baseline physiological differences. While the mechanism of the association remains unknown and cannot be addressed directly by this study, the data suggest that it can be explained neither as simply a reflection of perceived somatic symptoms nor as the result of differences in recreational drug and alcohol use. Further study is necessary to determine whether treating depression can alter the course of HIV infection.
