[SUBACUTE THYROIDITIS AND COVID-19 (REVIEW)]

Abstract

The COVID-19 pandemia has shown that there is not enough knowledge today to fully control it. Along with severe respiratory syndrome, attention has recently been paid to extrapulmonary lesions, including endocrinopathies. The aim of the study was to summarize the current literature data about the effects of the SARS-CoV-2 coronavirus on the thyroid gland. One of the most striking manifestations of viral aggression is de Quervain's subacute thyroiditis. The analysis of works from the most authoritative international abstract bibliographic databases was carried out using methods of analysis and processing of scientific resources. Based on the analysis, it was concluded that subacute thyroiditis can be both a clinical manifestation and a complication of COVID-19. The SARS-CoV-2 coronavirus can also trigger other thyroid diseases. The causes of subacute thyroiditis are considered to be the direct effect of the SARS-CoV-2 coronavirus on thyroid cells due to the use of ACE2 receptors, the subsequent inflammatory reaction and apoptosis, as well as central hypothalamus-pituitary mechanisms. The clinical variants of subacute thyroiditis in COVID-19 are diverse and have not been fully evaluated. In this regard, it can be concluded that the true incidence of subacute thyroiditis in COVID-19 is much greater, since it is masked by severe lesions of other organs.
