| Summary: | Background: Immune-reconstitution inflammatory syndrome (IRIS) is a dysregulated host inflammatory response following the initiation of appropriate therapy targeting an infectious disease. It is most commonly reported in human immunodeficiency virus patients following the initiation of antiretroviral therapy; however, IRIS can also be seen in immunocompromised patients without HIV, when the immune system is recovering. The diagnosis is confirmed using clinical and laboratory data after excluding differential diagnoses and concomitant infections. Case series: Here, we describe three cases of patients with IRIS that were treated at our tertiary care center. The first case involves a paradoxical IRIS in an HIV-positive patient with TB, where the re-initiation of ART led to an inflammatory response despite effective anti-tuberculous treatment (ATT). The second case highlights unmasking IRIS in an HIV-positive patient, where the initiation of ART revealed an underlying Epstein-Barr virus (EBV)-associated B-cell lymphoma. The third case describes paradoxical worsening of pulmonary TB in an HIV-negative patient, expanding the scope of IRIS beyond its conventional association with HIV infection. Conclusion: These cases illustrate the various manifestations of IRIS and emphasize the need for timely diagnosis and appropriate management strategies to mitigate the potentially severe outcomes associated with this syndrome. Our report highlights the challenges faced in the diagnosis of IRIS which impede prompt onset of therapy. |
