Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 3 to 21 years who have been diagnosed with COVID-19 and require hospitalization.

Probably not a fit

Patients with severe hepatic or renal dysfunction, significant pulmonary disease, or a history of severe neurocognitive delays may not benefit from this study.

What this trial studies

This study investigates the effects of arginine replacement therapy on mitochondrial function in children hospitalized with COVID-19. Participants aged 3 to 21 will be randomized to receive one of three doses of arginine three times daily for five days or until discharge. The research aims to address the observed acute arginine deficiency linked to severe COVID-19 and its complications, including multisystem inflammatory syndrome in children (MIS-C). By exploring the potential therapeutic benefits of arginine, the study seeks to improve patient outcomes in this vulnerable population.

Why it matters

Potential benefit: If successful, this therapy could enhance mitochondrial function and reduce complications associated with COVID-19 in children.

How similar studies have gone: While the approach of arginine therapy in COVID-19 is novel, previous studies have indicated a link between arginine deficiency and severe outcomes in COVID-19, suggesting potential for success.
