# Treatment Methods for Wilson's Disease
Wilson's disease typically requires long-term treatment aimed at removing and limiting copper accumulation. The choice of treatment depends on the stage of the disease, the severity of symptoms, and how well the patient responds to therapy.
Copper Chelation (First-Line Approach)
ProveniIncluded in official guidelines, or approved by EMA or FDA
Chelation therapy binds free copper in the blood and tissue, so it can be excreted via urine. This is often the first treatment, especially in symptomatic patients and in early stages.
Penicillamine is one of the oldest and most commonly used chelators. It works by binding copper and excreting this complex through the kidneys. Penicillamine can cause side effects such as rash, joint complaints, kidney function disorders, and sometimes a lupus-like presentation. For this reason, it is sometimes temporarily adjusted or discontinued. Regular blood and kidney function monitoring is necessary.
Trientine is another chelating agent that binds copper. It generally has fewer side effects than penicillamine, although rash and gastrointestinal symptoms can occur. Trientine is also used as a first-choice option or when penicillamine is not well tolerated.
Both substances require patience: it can take weeks to months before symptoms improve noticeably.
Zinc Therapy
ProveniIncluded in official guidelines, or approved by EMA or FDA
Zinc reduces copper absorption from food through a competitive mechanism in the intestine. This helps stabilize copper accumulation and prevents it from worsening. Zinc therapy is widely used as long-term maintenance treatment and also for treating asymptomatic carriers (people with mutations but no symptoms).
Zinc generally has fewer side effects than chelators, but can cause gastrointestinal disorders and sometimes copper-like tastes. It works more slowly than chelation, but can be well tolerated over years.
Correction of Malnutrition and Micronutrients
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many patients with Wilson's disease have deficiencies in vitamins and minerals, especially vitamin E, vitamin D, vitamin B12, and iron. This is caused by poor intestinal absorption and the disease itself.
Supplementation with these substances is part of overall care. This is done based on blood values and clinical presentation. This contributes to the recovery of bone and muscle strength and the reduction of neurological complications.
Liver Support in Acute Failure
ProveniIncluded in official guidelines, or approved by EMA or FDA
When Wilson's disease leads to acute liver insufficiency (fulminant hepatitis), intensive care in a hospital is required. This includes:
- **Infusions** to support electrolyte balance and blood clotting
- **Plasma exchange** (plasmapheresis): removal of toxic substances from the blood and replacement with healthy blood plasma
- **Dialysis**: if the kidneys are not functioning well
- **Medications** to support heart function and prevent infections
These measures give the liver time to recover or make the patient suitable for liver transplantation.
Liver transplantation
ProveniIncluded in official guidelines, or approved by EMA or FDA
When the liver is severely damaged (cirrhosis with decompensation) or in acute liver insufficiency that does not respond to treatment, liver transplantation is the only option. After transplantation, copper abnormalities disappear because the new liver typically does not have the problem.
After transplantation, lifelong medication is required to prevent rejection, and regular monitoring of kidney function and other organs is necessary. Transplantation outcomes in patients with Wilson's disease are typically good.
Medications to Support Neurological Symptoms
ProveniIncluded in official guidelines, or approved by EMA or FDA
Patients with neurological symptoms (tremor, spasticity, dystonia) receive medications that help alleviate these symptoms, without curing the underlying copper disease:
- **Baclofen** for muscle tension
- **Levodopa** or other agents for tremor-like movements (depending on the specific pattern)
- **Antidepressants** for facial muscles as part of dystonia
These medicines are adjusted to individual needs and tolerance.
Treatment of eye side effects (Kayser-Fleischer rings)
ProveniIncluded in official guidelines, or approved by EMA or FDA
The characteristic copper deposits in the eyes (Kayser-Fleischer rings) can fade and eventually disappear with successful copper binding. No separate treatment is needed for this; they respond to the same chelation and zinc therapy as the rest of the disease.
Regular eye examinations help to map the course of the disease.
Psychiatric and psychological support
ProveniIncluded in official guidelines, or approved by EMA or FDA
Many patients with Wilson's disease (especially those with neurological involvement) experience depression, anxiety disorders or personality changes. Professional support from psychologists, psychiatrists and social workers is an important part of care.
This may include cognitive behavioral therapy, antidepressant medication and counseling for patient and family.
Experimental gene therapy
ExperimentaliOngoing in study setting, outcome still unknown
Prime editing (PM577) is a gene technology being investigated in clinical trials. The principle is to repair the mutated ATP7B gene (which is responsible for copper normalization) in body cells. This is very early-stage research and is not yet available outside of study settings. The outcomes of these early trials will determine whether and when this becomes available.
Dietary adjustments
ProveniIncluded in official guidelines, or approved by EMA or FDA
Limiting copper-containing foods (shellfish and mollusks, nuts, chocolate, mushrooms, certain grains) helps reduce the total copper load. This is not a treatment, but an important supplementary measure.
Water from copper pipes should be avoided or replaced with filtered water. A dietitian with knowledge of Wilson's disease can provide personal advice.
