Selenium as a Potential Treatment for Moderately-ill, Severely-ill, and Critically-ill COVID-19 Patients.

Selenium as a Potential Treatment for Moderately-ill, Severely-ill, and Critically-ill COVID-19 Patients

Given its anti-viral, anti-oxidative, immune-enhancing, cytokine-modulating, and anticoagulant properties, the investigators hypothesize that Selenium infusion at supranutritional doses for moderately-ill, severely-ill, and critically-ill COVID-19 patients will prevent further clinical deterioration thus decreasing overall mortality and improving survival. To test this hypothesis, a prospective, single-center, phase II trial is proposed to assess the efficacy of Selenium in hospitalized adult patients with moderate, severe, and critical COVID-19 infections.

COVID-19 is a respiratory illness that is caused by the novel SARS-CoV-2. Illness severity can widely range from mild, moderate, severe featuring pneumonia, to critical. Despite ongoing extensive research to find a cure for COVID-19, there had been no proven, efficacious, and widely-available treatment for the disease. With the death toll rising in various parts of the US and the world, it is imperative that investigators work on determining new therapeutic modalities. This study relates to inpatient and critical care for COVID-19 patients.

The role of Selenium (Se) as a trace element involved in many biological processes and reactions is well established in various organisms. Particularly, Selenium is known to have anti-viral, anti-oxidative, cytokine-modulating, immune-enhancing, and anticoagulant properties that might be beneficial in COVID-19 infections given the pathophysiological processes involved in the disease. Multiple preclinical and clinical studies have shed the light on the various effects exerted by Selenium in multiple inflammatory conditions including acute lung injury and acute respiratory distress syndrome, as well as viral infections including HIV and Influenza. The study team aims to explore the possible role of Selenium in mitigating the inflammatory processes involved in COVID-19 infections and hence its effect on disease progression and mortality.

Patients with COVID-19 who exhibit the signs and symptoms of moderate or severe infection or are critically ill will receive Selenium infusion for 14 days. The working hypothesis of this trial is that selenium treatment would decrease the death rates and increase the rate of hospital discharges among hospitalized patients.
