title: Sibling cases of chronic recurrent hepatocerebral disease with hypercitrullinemia.
abstract: Two sibling cases with chronic recurrent hepato-cerebral syndrome which correspond to the nutritional form of hepato-cerebral disease entitled by Shikata et al. and the data of plasma free aminoacids analyses of these cases were reported. The one case is 27 years old male and the other case is 36 years old female. Their parents were cousins. Both cases have had unbalanced diet, especially liked legumes unusually. Their main symptom was recurrent disturbance of conciousness and convulsive seizures. Slight abnormality of liver function test and hyperammonemia were demonstrated. Electroencephalogram showed the pattern of triphasic wave. Coeliac angiography did not revealed a portal-systemic shunt. Hepatic biopsy specimen revealed liver fibrosis with fatty change in the one case and mild fatty change in the other case. Analyses of plasma free aminoacids showed particurally high level of citrulline in both cases. From the results of plasma free aminoacids analyses, it is considered that pathogenesis of these patients is congenital hereditary urea cycle disorders.
