title: Excretion of (sulfated) steroids in the urine and excretion of cholesterol sulfate in the feces of boys with recessive X-linked ichthyosis.
abstract: The excretion of sulfated steroids was investigated in the urine and feces of six boys aged 9 months to 7 years and 10 months who had recessive X-linked ichthyosis. Profiles of urinary total steroids as well as sulfated steroids were normal. Cholesterol sulfate excretion in the urine was not elevated. In the feces 2-20% of total cholesterol was cholesterol sulfate, whereas in the feces of 28 healthy children no cholesterol sulfate was demonstrable. In the 6 patients total cholesterol excretion (500-2,500 mumol/kg feces) was also elevated in comparison with the 28 healthy controls (150-700 mumol/kg feces, mean 365 mumol/kg feces).
