ABSTRACT
Objectives:
Structural aspects of HIV-1 integrase complex and role of integrase minor mutations and polymorphisms in ART effectiveness is still unknown. The objective of this study was to assess the 24 and 48 weeks (W) effectiveness of ART regimens in patients with Integrase Inhibitors (InSTI) minor mutations and polymorphisms receiving InSTI-based regimens.Methods:
We enrolled all ART-naïve or InSTI-naïve HIV-infected patients, with a baseline InSTI genotypic resistances test between 2011 and 2016. We analyzed integrase resistance mutations using the Stanford University HIV Drug Resistance Database (HIVdb Program, version 6.3.0). The outcome was virological response at 24 and 48 W of follow up (FU) according to snapshot analysis. We defined virological failure as two consecutive HIV-RNA > 50 copies/ml, or one >1000 copies/ml. Patients were divided in those presenting InSTI minor mutations (Group 1), and those with only polymorphisms or wild type (Group 2).Results:
We enrolled 83 patients. 81 patients reached 24 W of FU 2/20 (10%) and 4/61 (6.5%) showed virological failure in Group 1 and 2 respectively. 66 patients reached 48 W of FU 0/17 (0%) and 2/49 (4%) showed virological failure in Group 1 and 2 respectively. Interestingly, patients with polymorphisms G123S and R127K had higher risk of failure at 24 W (respectively, relative risk - RR - 36, IQR 2.1-613, p = 0.01; RR 36, IQR 2.1-613, p = 0.01) and patients with V72I had an higher risk of failure both at 24 W (RR 6.52, IQR 1.29-32.9, p = 0.02) and 48 W (RR 21.1, IQR 1.07-414, p = 0.04).Conclusions:
Our study showed that the presence of V72I, G123S and R127K polymorphisms could play a role in reducing InSTI effectiveness.Palabras clave
