title: Factors modifying the prognosis of Wilson's disease in childhood.
abstract: The prognosis of Wilson's disease was investigated in 96 patients, in whom the disease had presented before 15 years of age and had begun between 1965 and 1983 (when D-penicillamine was widely available in Japan). In the activities of daily living, the prognosis was poor in those patients presenting with neurological symptoms. Interruption of D-penicillamine treatment was seen in one third of the patients, and it worsened the prognosis. Toxic side effects were seen in about half of the patients, being more frequent in the patients with initial neurological symptoms. A disappointing 17% of patients with slight or no side effects discontinued the drug. Death occurred in eight patients of whom seven had had initial hepatic symptoms. Not only early diagnosis and treatment before the appearance of hepatic failure or neurological symptoms, but also treatment throughout life without interruption is important for improving the prognosis of Wilson's disease.
