Prognosis of Wilson's disease in childhood
Insights
Early diagnosis and treatment of Wilson's disease in children are crucial. Prompt intervention with D-penicillamine prevents symptom development and ensures excellent outcomes, particularly for hepatic manifestations.
Area of Science:
- Pediatric Hepatology
- Neurology
- Clinical Pharmacology
Background:
- Wilson's disease in children presents uniquely with rapid progression, common hepatic issues, and predominant dystonia, unlike adult presentations.
- Cerebral symptoms like dystonia are more common than tremor in pediatric Wilson's disease.
- Hepatic manifestations are a frequent initial presentation in childhood Wilson's disease.
Purpose of the Study:
- To evaluate the long-term efficacy of D-penicillamine treatment in pediatric Wilson's disease patients.
- To determine the impact of early diagnosis and treatment on disease progression and outcomes.
- To compare treatment responses based on initial clinical presentation (presymptomatic, hepatic, or neurological).
Main Methods:
- A cohort of 49 children under 15 with Wilson's disease received D-penicillamine treatment.
- Treatment duration ranged from 2 to 15 years.
- Patients were monitored for disease progression and treatment response based on initial symptoms.
Main Results:
- All presymptomatic children remained asymptomatic throughout the study period.
- Excellent treatment outcomes were observed in patients presenting solely with hepatic symptoms.
- Neurological symptoms, especially in those with a history of jaundice or ascites, showed a less favorable response to chelation therapy.
Conclusions:
- Early diagnosis and initiation of D-penicillamine treatment are vital for preventing Wilson's disease progression in children.
- Timely intervention significantly improves prognosis, enabling affected children to lead normal lives.
- Treatment effectiveness varies, with earlier and hepatic-stage interventions yielding superior results compared to advanced neurological disease.
Abstract:
Wilson's disease in childhood has several characters distinct from those in adults. The progression of the disease tends to be rapid, hepatic manifestations are common, cerebral symptoms related to dystonia are predominant, and tremor is rare. Forty-nine children with Wilson's disease under the age of 15 were treated with D-penicillamine for 2 to 15 years. None of the presymptomatic patients subsequently developed any symptoms of the disease. The results of treatment in patients who had exhibited only hepatic symptoms were also excellent. However, neurological manifestations associated with a history of jaundice or ascites responded less well to chelation. These observations clearly indicate that early diagnosis and treatment are extremely important to ensure normal lives for children with Wilson's disease.
