Summary

Low viral replication persistence and immune activation remain important therapeutic challenge in the new HAART era. They are associated with more rapid disease progression, increased risk of mortality and non-AIDS defining events. Soluble biomarkers are a convenient way of assessing immune activation and inflammation in HIV-infected patients receiving effective treatment. There are limited data describing the different effects of currently recommended antiretroviral regimens on immune activation and inflammation during HIV infection. Several studies have shown that raltegravir (the first approved drug from integrase inhibitor class) seems to have more impact on decreasing systemic inflammation compared with other drug classes. Integrase inhibitors may decrease inflammation and immune activation more than other antiretroviral drugs, because they are more lipid friendly and may concentrate better in enterocytes. The aim of this observational study is to compare the impact of different integrase inhibitor based regimen on changes in markers of inflammation (Il-2, IL-6, sTNFR-1, sCD14, sCD163, sICAM, hsRCP , sVCAM, LPS, D-dimer) during the first year of effective first-line combination. This is a 48-week observational retrospective study, to compare the change in infiammatory markers between naïve patients who start INI based regimen. Participants will be recruited from the HIV outpatient clinic. The study compare the impact of commonly used first-line antiretroviral drugs on soluble markers of inflammation and immune activation. The study is conducted on treatment-naive HIV-infected patients who experience a rapid and persistent virological response and that do not switch their initial regimen for at least 1 years. The analyses will be adjusted for baseline characteristics that might influence the choice of cART regimen or affect biomarker levels, such as age, smoking status, CD4 cell count, plasma HIV-1 viral load. Investigators enroll patients with a rapid and persistent virological response and that do not experience any blips. Cryopreserved plasma sample are obtained at baseline and at month 6 and 12 after treatment starting. Two NRTI backbone combinations (TDF/FTC vs ABC/3TC) and three third agents (RAL vs ELV vs DTG) will be compared in a factorial design. The results will be expressed as the estimated percentage difference between the mean fold changes observed with a given drug, using TDF/FTC and RAL as the reference groups for the comparison.
