Abstract

CONTEXT: Occurrence of Graves' disease (GD) has been reported following SARS-CoV-2 vaccine administration, but little is known about thyroid eye disease (TED) after SARS-CoV-2 vaccination.METHODS: We report two cases of TED activation following SARS-CoV-2 vaccination: one case of TED worsening in a patient with GD, and one of de novo active TED progressing to dysthyroid optic neuropathy in a patient with a history of Hashimoto's hypothyroidism. Our literature search revealed 8 additional reported TED cases associated with SARS-CoV-2 vaccination until June 2022. We review the characteristics, duration and management of TED following SARS-CoV-2 vaccination in these cases.RESULTS: Of all 10 reported TED cases following SARS-CoV-2 vaccination, four cases developed new onset TED and 6 cases with prior stable TED experienced significant deterioration. Six patients had known Graves' disease and 2 patients had Hashimoto's thyroiditis. Two cases progressed to dysthyroid optic neuropathy, 6 had moderate/severe active disease and 2 cases had mild disease that did not require treatment. Seven TED cases received teprotumumab and had a favorable response, two of which had prior limited response to initial prednisone or methylprednisolone and tocilizumab therapy.CONCLUSIONS: New diagnosis or deterioration of TED after mRNA SARS-CoV-2 vaccination can occur, with most cases described in patients with underlying autoimmune thyroid disease. Our report raises awareness to this potential complication to promote early recognition and prompt management of TED associated with mRNA SARS-CoV-2 vaccines. Further studies are needed to explore the mechanism of TED following mRNA SARS-CoV-2 vaccination, risk factors, prevention and treatment.
