Rapporteur report

Track B report by Silvia Nozza


In this session, speakers presented results of their studies about neurocognitive disorders, inflammation and performance of ART in the neurological district.

Dr. A. Antinori presented a study on 1,020 people, that evaluated if patients receiving an EFV-based regimen (N=324) had a worse neurocognitive performance when compared to those currently receiving an ARV regimen not including EFV (N=696).  He showed that EFV exposure and its duration were not associated with an increased risk of neurocognitive impairment.

Dr. L.A. Cysique explored the HAND prevalence in an Australian cohort of 90 HIV+ MSM, who have been compared to 49 HIV- donors. Rate of impairment was 53.3% in HIV+ patients, and 14.3% in HIV- individuals (p<0.0001). Substantial proportion of HAND was present despite undetectable viral load.

Dr. I. Grant evaluated the incidence and predictors of neurocognitive change over 35 (16-72) months in 436 participants in CHARTER study. Predictors of improvement occurred in 16.5% of subject,  and were education, absence of depressive disorders, lower AST and switch to ART.

Dr. K. Kallianpur analyzed the levels of proinflammatory cytokines in 52 patients treated successfully with ART, and showed that high circulating ratios to IL10 may mark brain atrophy independently of age, nadir CD4 and intracranial volume.

Dr. S.K. Patel examined high rate of mental depression in indian female sex workers, highligting that the HIV prevention efforts with this population require a focus on addressing the mental health issues.

Dr. R.J. Eliis evaluated prediction of impaired neurocognitive disorders in 1,626 non Hispanic white and African-American naive patients initiating ART. Overall NPZ-3 scores improved significantly over time (18.6% impaired at entry virus 14% at 4 years).  Predictors of not improvement were IDU, stroke and HBV coinfection (HBsAg positive).
