Abstract
Objective: Paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) is a frequent complication of antiretroviral therapy in resource-limited countries. We aimed to assess whether a 4 week course of prednisone would reduce morbidity in patients with paradoxical TB-IRIS without excess adverse events. Design: A randomised double blind placebo-controlled trial of prednisone (1.5mg/kg/day for 2 weeks then 0.75mg/kg/day for 2 weeks). Patients with immediately life-threatening TB-IRIS manifestations were excluded. Methods: The primary combined endpoint was days of hospitalization and outpatient therapeutic procedures, which were counted as one hospital day. Results: 110 participants were enrolled (55 to each arm). The primary combined endpoint was more frequent in the placebo than the prednisone arm (median hospital days 3 (IQR 0-9) and 0 (IQR 0-3) respectively; p=0.04). There were significantly greater improvements in symptoms, Karnofsky score, and quality of life (MOS-HIV) in the prednisone versus the placebo arm at 2 and 4 weeks, but not at later timepoints. Chest radiographs improved significantly more in the prednisone arm at weeks 2 (p=0.002) and 4 (p=0.02). Infections on study medication occurred in more participants in prednisone than placebo arm (27 vs 17 respectively; p=0.05), but there was no difference in severe infections (2 vs 4 respectively; p=0.40). Isolates from 10 participants were found to be resistant to rifampicin after enrollment. Conclusions: Prednisone reduced the need for hospitalisation and therapeutic procedures, and hastened improvements in symptoms, performance and quality of life. It is important to investigate for drug-resistant tuberculosis and other causes for deterioration before administering glucocorticoids.
