Abstract

This is an interventional proof of concept pilot study to explore the residual HIV replication. Thirty patients under effective HAART for over 2 years will be randomized after recruitment to six different groups and followed by 48 weeks. Group 1. Five patients will receive no further intervention in this group (control group) Group 2. Five patients will receive antiretroviral intensification with maraviroc and dolutegravir for 48 weeks. Group 3. Five patients will receive antiretroviral intensification with maraviroc and dolutegravir and the Sirtuin Histone deacetylase inhibitor nicotinamide for 48 weeks. Group 4. Five patients will receive antiretroviral intensification with maraviroc and dolutegravir for 48 weeks and the gold salt auranofin for 24 weeks. Group 5. Five patients will receive antiretroviral intensification with dolutegravir for 48 weeks, and dendritic cell vaccine.* Group 6. Five patients will receive antiretroviral intensification with dolutegravir for 48 weeks, dendritic cell vaccine, the Sirtuin Histone deacetylase inhibitor nicotinamide for 48 weeks, and gold salt for 24 weeks.* *These groups will not receive maraviroc intensification due to its potential effect in decreasing the chemotactic activity of dendritic cells (AU)
