Abstract
BackgroundTuberculosis-immune reconstitution inflammatory syndrome is an atypical, immoderate immune response mounted by the refurbishing immune system against the mycobacterium tuberculosis, commonly seen in HIV-infected individuals. ART significantly enhances one's immunity. However, this enhancement in immunity also sets off a number of inflammatory processes termed as Immune Reconstitution Inflammatory Syndrome (IRIS). MethodsThis observational study was conducted with the aim of assessing the incidence and pattern of TB-IRIS in people living with HIV/AIDS on ART registered at the ART Centre of S.C.B. Medical College and Hospital, Cuttack. They were evaluated for their plasma viral load and CD4 count at baseline. Thereafter, the plasma viral load was assessed every week and the CD4 count was assessed fortnightly. Each study participant was followed-up for a period of three months to look for any onset of TB-IRIS. ResultsA total of 286 patients were included the study. The overall incidence of TB-IRIS was 7.7%. The occurrence of paradoxical TB-IRIS was nearly double than ART-associated TB-IRIS. There was a significant rise in the CD4 cell count in the patients of both paradoxical (p = 0.001) and ART-associated (p = 0.017) TB-IRIS. The plasma viral load at baseline also showed significant differences from the levels documented at the appearance of the TB-IRIS both in both the types i.e. paradoxical (p = 0.001) and ART-associated (p = 0.012) TB-IRIS. ConclusionPeople with HIV/TB coinfection experience high morbidity and death from all kinds of TB-IRIS, necessitating specific attention. As HIV-positive cases and implementation of ART continue to rise, it's vital to quickly rule out TB coinfection.
