Abstract :ABSTRACT Objective: Thyroid gland can be affected both by cytokine storm and through angiotensin-converting enzyme 2 receptors. A worse prognosis has been described in patients with low fT3 levels. The aim of this study is to evaluate the prognostic significance of thyroid function during COVID-ICU hospitalization. Material and Methods: After ethical approval, 100 COVID-19 patients followed in the ICU between March 2020 and April 2021 was admitted to study. Patients with previous thyroid disease were excluded from study. Free triiodothyronine (fT3), free thyroxine (fT4), and thyroid-stimulating hormone (TSH) levels at ICU admission were evaluated. Clinical, demographic, laboratory, treatment, and outcome data were obtained from the patient\'s electronic hospital records. Mann Whitney U, Spearman correlation, binary logistic, and linear regression tests were used for statistical analysis. Results: TSH was in 31 patients, fT3 was in 37 patients, and fT4 was in 54 patients, which were outside the normal ranges. fT3 were lower in non-survivors than the survivors (p=0.036). However, the fT3 level was not the independent factor for mortality rate in linear regression analysis (p=0.652). APACHE II and procalcitonin levels as independent predictors of mortality (p=0.017). fT3 remained an independent factor for the length of ICU stay (p=0.024) and the length of hospital stay (p=0.031). Conclusion: fT3 is a prognostic indicator that can predict hospital and ICU length of stay in critically ill patients with Covid-19. In the future, a broader panel of validated biochemical markers, including fT3 levels, may become a simple tool for stratified management of patients with severe COVID-19.
