Small-vessel vascular disease in human immunodeficiency virus infection: the Hawaii aging with HIV cohort study.
BACKGROUND
This study is designed to determine the relationship between age and occurrence of cerebral manifestations of small-vessel ischemic vascular disease in human immunodeficiency virus (HIV)-seropositive individuals.


METHODS
Periventricular leukoaraiosis severity and white matter lesion volume were determined by magnetic resonance imaging of the brain of 57 HIV-seropositive individuals.


RESULTS
Cerebral small-vessel ischemic vascular disease manifestations correlated with age and systolic blood pressure, but not with HIV infection-related parameters.


CONCLUSIONS
These findings suggest that, in the era of highly active antiretroviral therapy, leukoaraiosis severity and white matter lesion volume may be more indicative of small-vessel ischemic vascular disease than HIV-related CNS pathology, and support the need for aggressive treatment of vascular risk factors in HIV-seropositive individuals.
