Increased Incidence and Severity of New Graves Disease Diagnoses in Youth During the COVID-19 Pandemic.

OBJECTIVE

Graves disease (GD), an autoimmune disease of the thyroid, is likely caused by a combination of genetic predisposition and environmental triggers. Recent data suggest that COVID-19 may be associated with the development of autoimmune disease. The aim of this study was to assess the incidence and characteristics of new GD diagnoses in youth prior to and during the COVID-19 pandemic.

METHODS

We performed a retrospective chart review of all new GD diagnoses in patients aged 0 to 18 years diagnosed at a tertiary care pediatric hospital between January 1, 2018, and December 31, 2021.

RESULTS

Over a 4-year period, 51 patients had been diagnosed with new-onset GD. We observed an increased incidence in new-onset GD during the pandemic compared with that in the 2 prior years (P = .01). During the pandemic period, heart rates (P = .03) as well as systolic (P = .005) and diastolic (P = .01) blood pressures were higher at initial evaluation, patients more frequently reported palpitations (P = .03) and tremors (P = .04), and an increased proportion of patients required beta-blockade treatment at diagnosis (P = .002). The percentage of patients requiring thionamide treatment and thionamide doses had been similar over time.

CONCLUSION

We identified an increase in new-onset pediatric GD diagnoses during the COVID-19 pandemic. In addition, youths had increased severity of symptoms and more frequently required beta-blockade treatment at diagnosis. Further study of the relationship between COVID-19 and autoimmune thyroid disease is needed.
