Summary
Thyrotoxicosis can cause severe intrahepatic cholestasis, a rare liver condition. Treatment of hyperthyroidism with methimazole normalized liver function and bilirubin levels in a unique patient case.
Area of Science:
- Hepatology
- Endocrinology
- Internal Medicine
Background:
- Intrahepatic cholestasis is infrequently associated with thyrotoxicosis.
- When cholestasis occurs in thyrotoxicosis, it is typically linked to congestive heart failure.
- The direct impact of hyperthyroidism on liver function warrants further investigation.
Observation:
- A 63-year-old male presented with jaundice and hyperthyroidism.
- Elevated plasma bilirubin reached 27.41 mg/dL.
- Exclusion of heart failure, autoimmune hepatitis, and viral hepatitis was confirmed through comprehensive examinations.
Findings:
- Hyperthyroidism-induced intrahepatic cholestasis can occur without congestive heart failure.
- Methimazole therapy led to simultaneous normalization of thyroid hormone and plasma bilirubin levels.
- The patient's extremely high bilirubin levels in the absence of other comorbidities are unprecedented.
Implications:
- This case highlights a rare but severe hepatic manifestation of thyrotoxicosis.
- Effective management of hyperthyroidism is crucial for resolving cholestasis.
- Further research is needed to elucidate the mechanisms linking thyroid dysfunction and intrahepatic cholestasis.
