Wilson's disease — Clinical Guidelines

Overview

Wilson's disease is an autosomal recessive disorder characterized by defective copper metabolism leading to copper accumulation in multiple organs, including the liver, brain, kidneys, and heart, causing diverse clinical manifestations 1.

Diagnosis

Key Diagnostic Criteria: Low serum ceruloplasmin levels, increased 24-hour urinary copper excretion, presence of Kayser-Fleischer rings, and ATP7B gene mutations 3.

Recommended Tests: Serum ceruloplasmin, 24-hour urinary copper, MRI (e.g., 'face of giant panda' sign), and genetic testing 3 5.

Diagnostic Scoring System: Utilize a scoring system based on clinical symptoms, biochemical tests, and genetic analysis 3.

Management

First-Line Treatments:

- Penicillamine: Initial treatment option, though monitor for adverse events 2. - Trientine: Alternative to penicillamine for managing adverse effects 2.

Adjunctive Therapies:

- Zinc salts: Used for maintenance therapy to prevent copper absorption 4. - Traditional Chinese Medicine (TCM): Can be integrated with Western therapies for additional benefits, though evidence is primarily observational 1.

Special Populations

Pediatrics: Present with liver disease more commonly than neurological symptoms; diagnosis relies on biochemical tests and genetic analysis 3.

Pregnancy: Requires careful anesthetic management during procedures like cesarean delivery due to potential complications 9.

Comorbidities: Consider neurological involvement, including severe spinal degeneration and status epilepticus, necessitating multidisciplinary care 5 8.

Key Recommendations

Use serum ceruloplasmin and urinary copper levels for initial diagnosis (Evidence: Strong 3).

Initiate treatment with penicillamine or trientine, monitoring for adverse events (Evidence: Moderate 2).

Incorporate zinc salts for long-term maintenance therapy to prevent copper absorption (Evidence: Moderate 4).

Consider genetic testing to confirm diagnosis and assess disease severity (Evidence: Moderate 3).

Integrate Traditional Chinese Medicine cautiously as adjunctive therapy, acknowledging limited strong evidence (Evidence: Weak 1).
