Porphyria cutanea tarda complicating Wilson's disease
Journal of the American Academy of Dermatology
|January 1, 1981
Summary
A rare coincidence of Wilson's disease and porphyria cutanea tarda occurred in a young woman undergoing copper chelation. Treatment cessation resolved symptoms, highlighting the interplay between these hepatic conditions.
Area of Science:
- Hepatology
- Metabolic Disorders
- Dermatology
Background:
- Wilson's disease is a genetic disorder causing copper accumulation.
- Porphyria cutanea tarda (PCT) is a liver disorder affecting heme production.
- Copper chelation therapy is a standard treatment for Wilson's disease.
Observation:
- A young woman with Wilson's disease developed symptomatic PCT during copper chelation.
- The patient was also consuming ethanol and using oral contraceptives.
- Blistering skin lesions and elevated urinary porphyrins indicated PCT.
Findings:
- Discontinuation of ethanol ingestion and oral contraceptives led to symptom resolution.
- Urinary porphyrin levels decreased significantly after treatment cessation.
- This marks the first documented co-occurrence of Wilson's disease and PCT.
Implications:
- Suggests potential interactions between copper metabolism, ethanol, oral contraceptives, and heme synthesis.
- Highlights the importance of considering medication and lifestyle factors in complex hepatic presentations.
- Informs therapeutic strategies for patients with co-existing Wilson's disease and PCT.
