Background: Intravenous immunoglobulin (IVIG) is commonly used to treat severe COVID-19, although the clinical outcomes remain unclear. This study evaluated the effectiveness of IVIG treatment for severe COVID-19.
Methods: This retrospective multi-center study evaluated 28-day mortality and time for SARS-CoV-2 RNA clearance in severe COVID-19 patients with or without IVIG treatment. Propensity score matching was used to control confounding factors. Logistic regression and competing risk analyses were performed.
Results: The study included 850 patients (421 patients received IVIG). No significant differences in 28-day mortality or time for SARS-CoV-2 RNA clearance were observed (p=0.357 and p=0.123, respectively). High-dose of IVIG treatment (>10 g/day) (n=27) was associated with decreased 28-day mortality (OR: 0.33, 95% CI: 0.14–0.77; p=0.011). The IVIG group had prolonged median hospitalization, less shock, and higher incidences of acute respiratory distress syndrome, myocardial injury. Furthermore, IVIG-treated patients were more likely to require non-invasive mechanical ventilation and less likely to require invasive mechanical ventilation.
Conclusions: IVIG treatment for severe COVID-19 patients was not associated with significant improvements in 28-day mortality or time for SARS-CoV-2 RNA clearance. However, some improvements in 28-day survival were observed for high-dose IVIG treatment (>10 g/day).
