Increased risk of IRIS-associated tuberculosis in HIV-infected patients receiving Integrase Inhibitors

Abstract

Background: Tuberculosis is associated with a risk of immune reconstitution inflammatory syndrome (IRIS) after ART initiation.

Methods: Data from all patients with newly diagnosed tuberculosis disease and uncontrolled HIV infection from 1997 to 2017 in a French center were retrospectively collected. We evaluated the incidence of tuberculosis-IRIS in patients initiating ART with or without integrase inhibitors (INSTI) RESULTS: Fifty-five patients were included: 21 receiving an INSTI regimen and 34 a non-INSTI regimen. Except with regard to ART regimen, the two groups were comparable (median CD4 of 85/mm³). The overall percentage of IRIS was 34% (19/55), with 52% IRIS in INSTI regimen and 23% in non-INSTI regimen respectively (P=0.04). In a multivariate logistic model, we observed an increased risk of IRIS in the INSTI regimen compared to the non-INSTI, with an OR at 3.33 [95% CI, 1.01-11.1] (P=0.05) CONCLUSIONS: ART containing integrase inhibitors could be associated with increased incidence of TB-associated IRIS.
