Abstract
Treatment with immunomodulators, such as intravenous immunoglobulin (IVIG), may attenuate inflammatory responses observed in the severe stages of acute respiratory distress syndrome (ARDS) caused by coronavirus disease 19 (COVID-19). We retrospectively evaluated the clinical courses of 12 COVID-19 patients who received IVIG at various stages of their illness, including within the first 72 h of clinical presentation, after initiation of mechanical ventilation, and after prolonged ventilation and ICU stay. The patients included 9 men and 3 women with a median age of 50 years (range 23-74), median Charlson Comorbidity Score of 2 (range 0-7), and median Acute Physiology and Chronic Health Evaluation Score of 13 (range 5-33) at the time of IVIG. The IVIG total dose ranged from 0.5 to 2.0 g/kg (median 1.25 g/kg) distributed over 1-4 daily doses. The most common regimen received was 0.5 g/kg daily for 3 days. The median time to IVIG administration was 9 days (range 0-48 days) after admission. The median time from first IVIG dose administration to hospital discharge was 14 days (range 3-48). The 5 patients who received IVIG ≤4 days of admission demonstrated a significantly shorter length of hospital stay after treatment (median 7 days, range 3-14 days) than the 7 patients who received it >7 days after admission (median 33 days, range 8-48 days, p = 0.03, Mann-Whitney U test). These cases demonstrate that IVIG may improve the clinical state of patients with moderate to severe COVID-19 infection. Despite very high illness severity scores, all patients survived hospital discharge. No thrombotic events occurred and IVIG was well tolerated, despite most cases demonstrating very elevated D-dimer suggestive of active intravascular fibrinolysis. We believe that IVIG warrants immediate clinical trial evaluation in COVID-19 to confirm its role as a mainstay treatment of moderate to severe COVID-19 infection as a means to reduce hospital stay and utilization of ICU resources, including mechanical ventilation, and potentially reduce mortality.
