[Wilson's disease in children - about 21 cases]

ABSTRACT

Wilson's disease is a familial affection, described the first time in 1912, which has an autosomic recessive transmission. It is characterized by an association of hepatic cirrhosis and neurologic manifestations caused by tissular accumulation of copper. To show clinical, genetic, diagnostic, therapeutic particularities and outcomes of this disease, we carried out a retrospective study concerning three pediatric departments in the Center of Tunisia [Kairouan, Farhat Hached and Sahloul hospitals]. We have collected 21 cases during a period of 17 years [from January 1983 to december 2000]. The finding's age of the disease ranges from 5 to 13 years [mean age 8 years and 9 months]. The sex ratio is 1,1. Consanguinity is found in 90% of cases. Finding circumstances are dominated by edematous and ascitic syndrome [28%] and by hepatomegaly [57.14%] a jaundice [19,5%], a pallor [9.52] and neurologic disorders [19% of cases]. A hepatic cytolysis was found in 38% and a decrease of prothrombin rate in 61% of cases. The ceruloplasmin concentration is lower than 200 mg/1 in 80% and a decrease in the blood rate of copper in 75% of cases. The urinary rate of copper was measured only in 9 patients; it was increased in 8 cases. The therapy consisted in D penicillamin in the first line. Outcome was marked by 3 cases of death. 18 patients are followed up and they are treated by D penicilamin
