Three Cases of COVID-19 Pneumonia That Responded to Icosapent Ethyl Supportive Treatment

BACKGROUND Icosapent ethyl, a form of eicosapentaenoic acid with anti-inflammatory activity, has been approved as an adjunctive treatment with statins in patients with hypertriglyceridemia. Icosapent ethyl is currently undergoing clinical trials to determine its anti-inflammatory effects in patients with coronavirus disease 2019 (COVID-19). This report describes 3 intensive care unit (ICU) patients with moderate to severe COVID-19 pneumonia treated with icosapent ethyl as part of their supportive care who had favorable outcomes. CASE REPORT Case 1 was a 75-year-old man with a past medical history of hyperlipidemia, hypertension, type 2 diabetes mellitus, obesity, and benign prostatic hyperplasia. Case 2 was a 23-year old man with a past medical history of type 2 diabetes mellitus and obesity. Case 3 was a 24-year old man with a history of autism. All cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection were confirmed from a nasopharyngeal swab using the Becton Dickinson nasopharyngeal reverse-transcription polymerase chain reaction. All patients in these cases were treated with a course of 2 g of icosapent ethyl twice a day by nasogastric tube. CONCLUSIONS This report of 3 cases describes the use of icosapent ethyl as a component of supportive treatments in ICU patients with moderate to severe COVID-19 pneumonia. However, as of yet there are no evidence-based treatments for SARS-CoV-2 infection from controlled clinical trials. The outcomes of ongoing clinical trials are awaited to determine whether icosapent ethyl has anti-inflammatory effects in patients with SARS-CoV-2 infection and which patients might benefit from the use of this adjunctive treatment.
