Occurrence of secondary cystathioninuria in children with inherited metabolic disorders, liver diseases, neoplasms, cystic fibrosis and celiac disease.

Secondary cystathioninuria was found in two of 46 children suffering from tumors, 
leukemia, liver disease, inherited metabolic disorders, cystic fibrosis and celiac disease. 
Of these two patients, one had congenital biliary atresia and the 
other cytomegalovirus infection. Seven further children had only moderately elevated excretion 
of cystathionine. It is suggested that secondary cystathioninuria is uncommon in 
the disease investigated.
