Thyroid Storm in a Patient With COVID-19

Area of Science:

• Endocrinology
• Infectious Diseases
• Critical Care Medicine

Background:

• Thyroid storm is a life-threatening endocrine emergency characterized by severe thyrotoxicosis.
• The global COVID-19 pandemic, caused by SARS-CoV-2, presents unique challenges in clinical management.
• Infections are known triggers for thyroid storm, necessitating investigation into potential links with novel pathogens.

Observation:

• A 25-year-old female presented with symptoms of thyrotoxicosis and respiratory distress.
• Diagnostic workup confirmed a thyroid storm (Burch-Wartofsky criteria) and positive SARS-CoV-2 infection.
• Key findings included suppressed TSH, elevated free T4 and total T3, positive thyroid-stimulating immunoglobulin, and characteristic thyroid ultrasound findings.

Findings:

• The patient experienced a concurrent thyroid storm and COVID-19 infection.
• Prompt treatment with antithyroid medications and supportive care led to symptom improvement.
• The COVID-19 illness course was uncomplicated, with resolution of respiratory symptoms.

Implications:

• This case highlights the potential for SARS-CoV-2 infection to precipitate or exacerbate thyroid storm.
• Clinicians should maintain a high index of suspicion for COVID-19 in patients with thyrotoxicosis and respiratory symptoms.
• Considering COVID-19 testing in such presentations may improve diagnostic accuracy and patient outcomes.
