Thyroid status and severity or mortality of COVID-19

Abstract

Implication for health policy/practice/research/medical education The non-thyroidal illness syndrome is characterized by low triiodothyronine in people with normal thyroid status, commonly occurring in seriously ill patients or individuals with malnutrition. Several studies showed people with severe COVID-19 had much lower free triiodothyronine levels than the patients who had less sever COVID-19. Therefore, free serum triiodothyronine may become a predictor of the severity of COVID-19 and an indicator for its management.
