Subacute thyroid and SARS-CoV-2 relationship

Abstract

Background: This study aims to research the relationship of subacute thyroiditis with SARS-CoV-2. The prevailing risks of predisposition to certain diseases or organ dysfunctions even after surviving the disease are discussed more frequently each day. Aim: Could SARS-CoV-2 be considered as a triggering factor in patients diagnosed with subacute thyroiditis? Investigating the relationship between subacute thyroiditis and SARS-CoV-2. Methods: Thirty-three patients diagnosed with subacute thyroiditis between 01.11.2020 and 01.04.2020 were included in the study. Patients who tested positive for SARS-CoV-2 throughout the examinations performed at the time of the diagnosis for subacute thyroiditis and patients who were previously diagnosed with Covid-19, who tested positive for SARS-CoV-2, and subsequently diagnosed with subacute thyroiditis within 30 days have been included in the study. Clinical evaluation of the patient, thyroid hormone values, CRP values, sedimentation levels, and thyroid ultrasonography images were considered to diagnose subacute thyroiditis; patients whose results were compatible with subacute thyroiditis were diagnosed with subacute thyroiditis, and they were included in the study. Results: It was found that 5 (15%) of the 33 patients included in the study had Covid-19 disease before the diagnosis of subacute thyroiditis and were isolated for the SARS-CoV-2 virus. Conclusion: The SARS-CoV-2 virus can be considered a triggering factor for subacute thyroiditis. We believe that researching this relationship on a broader patient population will bring more clarity to the subject. Although encountered in only one of our cases, the Coronavirus vaccine and SAT relationship may shed light on future studies. Keywords: Subacute thyroiditis, SARS-CoV-2, COVID-19
