Abstract

Huntington Disease (HD) and human immunodeficiency virus (HIV) are both associated with neurodegeneration in the cerebral cortex and striatum. The rate of striatal degeneration is a known predictor of symptom onset in HD indicating a potential neurobiological link between HD and HIV. To determine if the presence of pre-existing HIV infection would trigger a significantly earlier age of symptom onset (ASO) in HD-mutation carriers when compared to non-infected HD subjects. This was a retrospective analysis of the Enroll-HD database that included participants with a CAG repeat of at least 36. Participants with HD and a comorbidity of HIV that was diagnosed prior to their reported ASO were identified and compared to participants with HD who did not have HIV. An ANCOVA analysis was performed to investigate the differences in ASO between the HIV and non-HIV groups. Sex, drug use, and CAG repeat number were used as covariates. The average ASO of HD subjects with previous HIV infection (n = 8) was 9.1 years earlier than non-HIV infected HD subjects (n = 3259) [F (1, 3267) =10.05, p = 0.002]. Despite low numbers of participants in the HIV group, the calculated effect size of this difference was 1.07. The known neurobiological changes ca...Continue Reading
