Injection of intravenous immunoglobulin (IVIg) for the treatment of Coronavirus induced cytokine storm

COVID-19 disease is the cause of daily morbidity and mortality worldwide due to its high transmissibility and pathogenicity. To date, intravenous immunoglobulin (IVIg) injection has been used as one of the various treatments for this disease. This study aimed to determine the effect of IVIg injection on the treatment of patients with Coronavirus-induced cytokine storm.

A total of 174 patients with COVID-19 were included in this study based on their clinical characteristics and laboratory findings and were divided into two groups of IVIg recipients and non-recipients according to the treatment they received. Statistical analysis was performed using SPSS version 22.0. A p-value less than 0.05 was considered statistically significant.

IVIg was used to treat merely 20 patients and Kaletra and hemoperfusion drugs were used more among IVIg recipient patients (P=0.003 and P=0.001, respectively). COVID-19-positive PCR tests were significantly more frequent among IVIg recipients (P=0.026). The polymorphonuclear neutrophil (PMN) count (P=0.007) and sodium level (P=0.007) were significantly higher in the IVIg recipient group on the first admission day. Moreover, INR levels in the IVIg recipient group were significantly lower on the seventh admission day (P=0.020). The median of total intensive care unit (ICU) duration of hospitalization among IVIg recipients was significantly higher (P=0.001).

It seems that the use of IVIg in COVID-19 patients should be further investigated.

IVIg injection could decrease mortality and slightly increase the survival rate among COVID-19 patients.
