Alagille syndrome: cutaneous manifestations in 38 children.
The Alagille syndrome is one of the most common inherited disorders causing chronic liver disease during childhood. During the 1990s, 38 children with Alagille syndrome were evaluated at two pediatric centers in Buenos Aires, Argentina. Characteristic clinical, humoral, and cutaneous features were analyzed. The average age of diagnosis was 29 months old (range of between 2 months and 15 years). Cholestasis was evident in 92% of patients during the neonatal period. Family antecedents related to the syndrome were found in 18.5% of the patients. Peculiar facies developed in 85% of patients. Chronic cholestasis and pruritus were observed in all of the patients and jaundice was evident in 78%. Eighty-four percent of the patients had heart disease (pulmonary stenosis, intraauricular communication, intraventricular communication), 76% of them showed growth retardation, and vertebrae abnormalities were found in 63%. Embryotoxon appeared in 76% of patients, and renal disturbances in 21%. Eleven children (28%) had xanthomas, in the neck, elbows, palms, helixes, inguinal area, gluteus, and knees. The earliest findings appeared in the first months of life, and the latest at 5 years of age. The xanthomas located in the folds had a stony aspect. Cholesterol levels ranging from 220 to 1600 mg percentage (mg%) were demonstrated in all of the children with xanthomas. Liver transplantation was performed in seven of the patients (18.4%). Two of them died after this operation. The disappearance of xanthomas after transplantation was remarkable in all of the patients.
