Thyroid storm in a patient with fulminant hepatic failure

Area of Science:

• Endocrinology
• Hepatology
• Critical Care Medicine

Background:

• Graves' disease is an autoimmune disorder leading to hyperthyroidism.
• Fulminant hepatic failure is a rare but life-threatening complication of severe thyrotoxicosis.
• Thyroid storm represents a critical exacerbation of hyperthyroidism.

Observation:

• A 28-year-old male with Graves' disease presented with fulminant hepatic failure, jaundice, and gastrointestinal symptoms.
• Initial thyroid function tests revealed suppressed TSH and elevated T3 and Free T4, indicative of thyrotoxicosis.
• Liver function tests confirmed severe hepatic dysfunction, necessitating emergent liver transplantation.

Findings:

• The patient developed post-transplant complications including heart failure and acute respiratory distress syndrome.
• A diagnosis of thyroid storm was established based on clinical presentation and laboratory findings.
• Emergent thyroidectomy was performed, leading to rapid reversal of post-transplant multi-organ dysfunction.

Implications:

• This case highlights thyroid storm as a critical differential diagnosis in patients with unexplained hepatic failure.
• Early recognition and management of thyroid storm are crucial for improving outcomes in patients with severe thyrotoxicosis.
• Multidisciplinary management involving endocrinology, hepatology, and critical care is essential for these complex cases.
