IRIS

This study was a multicenter, open-label, randomized controlled clinical trial designed to evaluate the efficacy and safety of glucocorticoids in preventing paradoxical immune reconstitution inflammatory syndrome (IRIS) in patients with AIDS complicated by opportunistic infections. A total of 262 HIV-infected patients with a baseline CD4⁺ T-cell count \<100/μL, who were scheduled to initiate antiretroviral therapy and had opportunistic infections, were enrolled and randomly assigned in a 1:1 ratio to the prednisolone group or the control group. Participants in the treatment group received prednisolone at 40 mg/day for 14 days followed by 20 mg/day for 14 days, whereas the control group received no glucocorticoid intervention. All participants were followed for 12 weeks. The primary endpoint was the incidence of paradoxical IRIS within 12 weeks. Secondary endpoints included time to IRIS onset, duration of IRIS, mortality, hospitalization, serious adverse events, CD4⁺ T-cell counts, and HIV-RNA suppression. The findings will provide evidence-based support for the prevention of paradoxical IRIS.
