Prevalence of Hypothyroidism Among Patients With COVID-19, Tehran, Iran

Objective: Numerous comorbidities are involved in the severity of Corona Virus Disease 2019 (COVID-19). Hypothyroidism's impact on COVID-19 is yet to be understood properly. Cellular immunity and different cytokines, on the other hand, are thought to play a role in the development and progress of COVID-19 and thyroid disease, according to earlier research. The goal of this study was to find out how common (prevalent) hypothyroidism was among COVID-19 patients and its possible influence on the disease prognosis on hospitalized patients at a Tehran University Hospital. Methods: : Demographic information and other data related to our study, mainly comorbidities, were collected from 493 COVID-19 patients’ medical records and analyzed . Results: : We identified that hypothyroidism was significantly prevalent in hospitalized COVID-19 patients than in the general population. Overall, in patients with hypothyroidism (n=65), n=21(32.3%) patients expired of whom 14 (66.7%) patients were females and 7 (33.3%) were males. In these patients, no statistically significant difference was observed between the expired and discharged groups (Adjusted Odds Ratio (OR adj ): 1.04 (95% Confidence Interval (CI): 0.59-1.83 p-value=0.87). As a result, hypothyroidism was not linked to an increased risk of death. Conclusion: In this current study, we demonstrated that the prevalence of hypothyroidism was higher in hospitalized COVID-19 patients than in the normal population especially in females but without significant adverse effects on the risk of mortality from this disease.
