HMGB1/anti-HMGB1 antibodies define a molecular signature of early stages of HIV-Associated Neurocognitive Isorders (HAND).

Background: HIV-associated neurocognitive disorders (HAND) persist in the post-HAART era, characterized by asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorders (MND). High mobility group box 1 (HMGB1) is a non-histone chromosomal protein widely expressed in the nucleus of all eukaryotic cells, including brain cells, which acts as a potent proinflammatory cytokine when actively secreted from immune cells. Recent reports suggested that HMGB1 acts on microglial cells to promote neuroinflammation.

A decreasing CD4/CD8 ratio over time and lower CSF-penetrating antiretroviral regimens are associated with a higher risk of neurocognitive deterioration, independently of viral replication.

Persistent immune activation is one of the suspected causes of HIV-associated neurocognitive disorders (HAND) in cART era. The CD4/CD8 ratio has been recently showed as a marker of immune activation and HAND. Our aim was to analyze if a decrease in the CD4/CD8 ratio over time could have an impact on neurocognitive deterioration.

Virologically suppressed patients with asymptomatic and symptomatic HIV-associated neurocognitive disorders do not display the same pattern of immune activation.

Objectives: Inversion of the CD4:CD8 ratio is a marker of immune activation and age-associated disease. We measured the CD4:CD8 ratio as a marker of cognitive impairment in HIV-infected patients and explored differences according to clinical severity.

Methods: Post hoc analysis of data from two prospective cohorts of HIV-infected patients randomly selected to undergo neuropsychological tests was performed.

Can high central nervous system penetrating antiretroviral regimens protect against the onset of HIV-associated neurocognitive disorders?

Objective: To assess changes over time in neuropsychological test results (NPr) and risk factors among a regularly followed HIV-infected patient population.

Methods: Prospective cohort of HIV-infected patients randomly selected to undergo neuropsychological follow-up. Test score was adjusted for age, sex and education.
