Ursodeoxycholic acid (UDCA) has been shown to improve pruritus, alanine aminotransferase (ALT), and cholesterol levels in children with intrahepatic cholestatic liver disease. However, the effect of UDCA on quantitative tests of hepatic function in children is uncertain.


A 2.5-year, open label, crossover study, was designed to determine the effect of UDCA (15-20 mg/kg per day for 12 months, off for 6 months, and on again for 12 months) on clinical symptoms, biochemical test results, galactose and caffeine elimination half-lives (t1/2), and quantitative hepatic scintigraphy in 13 subjects aged 13.1 +/- 2.1 years (10 of whom completed the entire study), with intrahepatic cholestasis.


Pruritus improved with UDCA in the 6 patients with pruritus on entry into the study. At 12 months, there was a significant decline in ALT, gamma-glutamyl transpeptidase, and plasma levels of copper and manganese, with no further decline in these levels at 24 months. There were no changes in bilirubin or cholylglycine levels. After therapy was discontinued at 12 months, UDCA was restarted within 1 month in 9 of 12 patients in response to a doubling of ALT (n = 6) or worsening pruritus (n = 3). Galactose t1/2 increased after 12 months, with no further increases after 24 months of UDCA therapy, whereas caffeine t1/2 did not change. There were no significant changes in hepatic scintigraphy throughout the study.


These data suggest that although UDCA therapy improves pruritus and results in a reduction in ALT and gamma-glutamyl transpeptidase, UDCA therapy did not improve quantitative measures of hepatic function in children with intrahepatic cholestasis.
