COVID-19 patients with moderate pneumonia (n= 100).
Intravenous immunoglobin (IVIG, n= 50).
Standard of care (SOC, n= 50).
Duration of hospital stay was significantly shorter in IVIG group to that of SOC alone (7.7 vs. 17.5 days). Duration for normalization of body temperature, oxygen saturation and mechanical ventilation were significantly shorter in IVIG compared to SOC. Percentages of patients on mechanical ventilation in two groups were not significantly different (24% vs. 38%). Median time to RT-PCR negativity was significantly shorter with IVIG than SOC (7 vs.18 days). There were only mild to moderate adverse events in both groups except for one patient (2%), who died in SOC.
