Practical recommendations and new therapies for Wilson's disease

Area of Science:

• Hepatology
• Neurology
• Genetics

Background:

• Wilson's disease is an inherited disorder characterized by excessive copper accumulation in the body.
• Copper primarily damages the liver and brain, leading to diverse clinical manifestations.
• Delayed diagnosis is common due to the protean and often non-specific symptoms of Wilson's disease.

Purpose of the Study:

• To highlight the critical importance of early diagnosis in Wilson's disease.
• To review diagnostic approaches for Wilson's disease.
• To discuss current therapeutic strategies for Wilson's disease.

Main Methods:

• Diagnostic evaluation includes urine copper levels, blood ceruloplasmin, slit lamp examination for Kayser-Fleischer rings, and liver biopsy with copper assay.
• Therapeutic agents include zinc, penicillamine, trientine, and tetrathiomolybdate.
• Treatment strategies are tailored to disease presentation (presymptomatic, liver failure, neurological disease).

Main Results:

• Effective therapies exist for Wilson's disease, but delay in diagnosis increases the risk of irreversible organ damage.
• Zinc is recommended for maintenance therapy, presymptomatic patients, and pregnant patients due to its efficacy and safety.
• Combination therapy (trientine and zinc) is used for mild liver failure, while tetrathiomolybdate is preferred for initial neurological disease treatment.

Conclusions:

• Early recognition and diagnosis of Wilson's disease are paramount for effective management and prevention of severe complications.
• Treatment choice depends on the clinical presentation, with specific agents preferred for initial management versus long-term maintenance.
• Ongoing research and clinical experience guide the optimal use of available anticopper agents to improve patient outcomes.
