Clinical outcomes among HIV/tuberculosis-coinfected patients developing immune reconstitution inflammatory syndrome after HAART initiation in South India

Abstract

Introduction: We determine the frequency and immunological outcome of developing immune reconstitution inflammatory syndrome (IRIS) among HIV/tuberculosis (TB) - coinfected Indians receiving highly active antiretroviral therapy (HAART). Methods: Patients coinfected with TB and HIV who initiated HAART were classified based on treatment outcomes (IRIS and non-IRIS) utilizing an observational HIV/AIDS cohort. Results: A total of 1731 HIV/TB-coinfected patients initiated HAART, and 95 of these patients (5.5%) developed TB-IRIS, with an incidence rate of 0.26 per 100 person-years. Patients who developed IRIS had significantly higher CD4 counts than non-IRIS patients at the time of initiating HAART, as well as after 6 months, 18 months, and 24 months following HAART initiation (P
