Wilson's disease treatment aims to reduce copper levels in tissues to normal.
In this regard, chelating agents such as penicillamine (Cuprimine, Depen) have shown significant effects in most patients.
Additionally, trientine (Syprine) can also be considered.
It is important to regularly monitor urine tests and complete blood counts during treatment to detect any allergic reactions and side effects early.
If an allergy occurs, switching medications or discontinuing treatment should be considered.
Oral zinc salts can limit copper absorption in the intestines and serve as an adjunctive treatment with minimal side effects.
If liver damage has reached an irreversible stage, liver transplantation must be considered.
Dietary restrictions should include avoiding foods high in copper, such as chocolate, nuts, dried fruits, animal liver, and shellfish.

More Info
Wilson's disease, also known as hepatolenticular degeneration, is a genetic disorder that leads to excessive accumulation of copper in the body, particularly affecting the liver and brain. The management of Wilson's disease primarily focuses on reducing copper levels and preventing its toxic effects. The treatment strategies have evolved over the years, and several effective medications are currently available.
The cornerstone of Wilson's disease treatment is the use of chelating agents, which help remove excess copper from the body. The most commonly used chelating agent is penicillamine (brand names include Cuprimine and Depen). Penicillamine works by binding to copper, allowing it to be excreted through the kidneys. Most patients respond well to this treatment, but it is essential to monitor for potential side effects, such as allergic reactions or changes in blood counts, which can occur during therapy. Regular urine tests and blood counts are recommended to detect any adverse effects early.
Another chelating agent that can be used is trientine (brand name Syprine). Trientine is often considered for patients who cannot tolerate penicillamine due to its side effects. It has a similar mechanism of action but may have a different side effect profile, making it a suitable alternative for some patients.
In addition to chelation therapy, zinc salts are also utilized in the management of Wilson's disease. Zinc works by inhibiting the intestinal absorption of copper, thus reducing the amount of copper that enters the bloodstream. It is often used as an adjunct therapy alongside chelating agents, especially in patients with mild disease or as a maintenance therapy after initial chelation.
In cases where liver damage has progressed to an irreversible stage, liver transplantation may be necessary. This is particularly true for patients who develop severe liver dysfunction or liver failure due to copper accumulation. Transplantation can effectively cure Wilson's disease, as the new liver will not have the genetic defect that causes copper accumulation.
Dietary management is also an essential aspect of Wilson's disease treatment. Patients are advised to avoid foods high in copper, such as chocolate, nuts, shellfish, and organ meats. This dietary restriction helps minimize copper intake and supports the overall treatment plan.
In summary, the effective management of Wilson's disease involves a combination of chelation therapy with agents like penicillamine and trientine, the use of zinc salts to limit copper absorption, and dietary modifications to reduce copper intake. Regular monitoring and follow-up are crucial to ensure the effectiveness of the treatment and to manage any potential side effects. In advanced cases, liver transplantation may be considered as a definitive treatment option. As research continues, new therapies and strategies may emerge, but the current treatment modalities have proven effective in managing this complex disorder.
