Idiopathic, recurrent cholestasis is characterized by episodes of obstructive jaundice often preceded by pruritus, steatorrhea, and purpuric rash. Between episodes of jaundice the liver histology is normal. We report a case of idiopathic, recurrent cholestasis occurring in a 14-year-old Caucasian girl who has experienced seven episodes of jaundice since 8 years of age. Serum alkaline phosphatase elevation preceded clinical jaundice. During remission the bromsulphalein excretion was normal. Response to oral steroids occurred when used after 4 weeks of jaundice. Cholestyramine resin and cyproheptadine relieved pruritus and in combination may have prevented progressive jaundice when administered early. Light microscopy during exacerbation showed centrilobular cholestasis with a slight mononuclear infiltration of the portal triad.
The electron microscopic examinations demonstrate dilated bile canaliculi with altered microvilli. Serial liver biopsies over 6 years show no fibrosis or cytoplasmic alterations of hepatocytes. Of the 24 reported cases of idiopathic, recurrent cholestasis, two-thirds have been in males and had onset of jaundice under 20 years of age. This younger age of onset merits a greater awareness by the practicing pediatrician. After the diagnosis is established by clinical, biochemical, and morphologic studies, a benign course can be anticipated.
