Investigation of cardiac adverse effects in COVID-19 ARDS patients treated with intravenous immunoglobulin

OBJECTIVE: The popularity of intravenous immunoglobulin (IVIG) therapy in Acute Respiratory Distress Syndrome (CARDS) secondary to COVID-19 infection is increasing day by day. In this study, we aimed to retrospectively evaluate the possible cardiac effects in our CARDS patients treated with IVIG. METHODS: Demographic and clinical characteristics, mortality, sequential electrocardiography (ECG), echocardiography, cardiac markers, and other laboratory parameters of CARDS patients who received IVIG treatment were recorded. RESULTS: The mean age of the patients was 68.7±13.6%, and 70.5% were female. The mean number of days of hospitalization in the intensive care unit was 18.2±9.7, and the mortality rate was recorded as 35.2%. No pathological rhythm or ischemic change was observed in sequential ECG follow-ups. However, in consecutive ECO follow-ups, the sPAP values at the treatment end were numerically lower, although not statistically significant. CONCLUSION: Our study suggests that IVIG therapy may be used safely in COVID-19 patients with cardiovascular side effects. However, due to the high risk of coagulopathy in these patients, the use of IVIG therapy in COVID-19 infection should be monitored with close monitoring, as it may increase the potential for cardiovascular risk. Furthermore, monitoring cardiac parameters are also essential as it may predict high cardiovascular risk in patients. For this reason, patients need lower infusion rates, steroid combination, adequate hydration, and effective anticoagulation therapy to avoid these side effects.
