Biochemical liver abnormalities in Turner's syndrome

Background Turner's syndrome is a chromosomal abnormality (45X0) which may be associated with various autoimmune disorders and disease conditions; how ever, association with liver pathology has rarely been reported. Objectives The aim of this work was to assess liver function abnormalities in a group of adult patients with Turner's syndrome, Design and methods Liver function tests were performed in 16 women with Tur ner's syndrome all of whom had been previously treated with oestrogens, Pat ients with liver abnormalities were further studied with hepatic ultrasonog raphy, serological markers of viral hepatitis and autoantibody determinatio ns, Results Seven women (43.7%) presented with asymptomatic liver cholestasis; these patients were older than those with normal biochemical values (33.4 /- 5.2 vs 24.7 +/- 5.7 years, P< 0.05). Liver function abnormalities appear ed 7.8 +/- 4.9 years after starting oestrogen therapy; however, no improvem ent of liver function was observed 20 +/- 17.7 months after stopping treatm ent. All of these women were anti-HCV and HBsAg negative, and autoimmune he patitis was ruled out in all cases. Liver ultrasound only disclosed homogen eous liver enlargement in one case and cholelithiasis without bile duct abn ormalities in another, Four patients underwent a percutaneous liver biopsy of which two were normal and two showed minimal non-specific changes. Conclusions The incidence of biochemical liver cholestasis in this group of patients with Turner's syndrome is high. Oestrogen therapy and autoimmune disorders do not seem to be the responsible causes. It appears that this is a benign condition which does not seem to reflect any substantial liver dy sfunction. The aetiology remains uncertain. fur J Gastroenterol Hepatol 11: 1037-1039 (C) 1999 Lippincott Williams & Wilkins.
