AB We examined the effects of human immunodeficiency virus (HIV) infection
and chronic alcohol consumption on cerebral phosphorus metabolites to
determine if chronic alcohol abuse is a risk factor for the progression
of neurological effects of HIV infection. We studied 15 HIV- alcoholics,
8 HIV- light/nondrinkers, 32 HIV+ alcoholics, and 41 HIV+
light/nondrinking men, with both HIV+ groups having similar CD4
lymphocyte counts. We used localized 31-phosphorus magnetic resonance
spectroscopy after magnetic resonance imaging to examine two brain
volumes in superior white matter and subcortical gray matter. Chronic
alcohol consumption was associated with reduced white matter
concentrations of phosphodiester (PDE) and phosphocreatine (PCr). Also
in the white matter, acquired immune deficiency syndrome (AIDS) and
AIDS-related complex (ARC) were associated with reduced concentrations
of PDE and PCr, compared with both HIV- and clinically asymptomatic HIV+
subjects. Because no alcohol-by-HIV interactions were detected, the
effects of HIV infection and alcohol abuse were cumulative. This is
reflected in a successive decrease of white matter PDE and PCr
concentrations in the order HIV- light/nondrinkers/HIV- alcoholics/HIV+
light/nondrinkers/HIV+ alcoholics. Subcortical gray matter PDE
concentrations were lower in ARC/AIDS alcoholics than in HIV-
light/nondrinking individuals. These findings suggest altered brain
phospholipid metabolites and energy metabolites with alcohol abuse and
HIV infection. They demonstrate that the adverse metabolic effects of
HIV on the brain are augmented by chronic alcohol abuse.
