Summary

Neurocognitive impairment (NCI) is one of the serious complications of elderly HIV-infected patients. The destruction of intestinal mucosal barrier and imbalance of bacterial flora caused by aging and HIV infection may be an important factor promoting the occurrence of NCI. Therefore, it is important to understand changes in gut microbiota of HIV-infected patients with NCI. Higher dietary intake of the essential fatty acid docosahexaenoic (DHA) has been associated with better cognitive performance in several epidemiological studies. To date, data are limited showing that DHA administration leads to benefits for behavioral disorders by modulating gut microbiota composition; the few studies on this subject, mostly completed in animal models. Moreover，low levels of DHA have been found in HIV-infected patients. The effect of DHA supplementation on gut microbiota and NCI status of HIV-positive patients have not been evaluated yet. Investigators aim to implement a case-control study to identify the relationship between gut microbiota and NCI in HIV-infected patients. At the meantime, investigators aim to implement a randomized, double-blind, placebo-controlled clinical trial to assess DHA supplementation in HIV-infected patients with NCI for 16 weeks. The effect of DHA on gut microbiota and NCI were evaluated. Also, investigators aim to identify if the benefits for NCI of DHA caused by modulating gut microbiota composition and metabolites.

Conditions
