Liver dysfunction in Turner's syndrome: prevalence, natural history and effect of exogenous oestrogen

Koulouri, Olympia, Ostberg, Julia, Conway, Gerard S.·2008·Clinical Endocrinology

Abstract

OBJECTIVES: Raised liver enzymes are a common feature of Turner's syndrome (TS), but the cause remains unclear. We studied the hepatic function in a large cohort of women with TS and tested the effect of increasing doses of hormone replacement therapy (HRT) on liver function tests (LFTs). DESIGN AND PATIENTS: LFTs were assessed in three studies. A cross-sectional review of liver function of 125 women (median age: 31 years), a longitudinal study of 30 women (mean follow-up period: 8 years) and a dose-response study of 14 women with TS and 11 controls with hypogonadism, who received oral 17-beta-oestradiol (E(2)) 1, 2 and 4 mg daily in a cyclical formulation for 12 weeks each. MEASUREMENTS: Clinical features, oestrogen use and metabolic parameters were compared to liver enzymes (gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT) and alkaline phosphatase (ALP)), albumin and bilirubin. LFTs were also measured during each treatment interval of the dose-response study. Hepatic autoimmunity was sought in the cross-sectional study. RESULTS: When compared to the control population, as opposed to reference ranges, 91% of women with TS demonstrated liver enzyme elevation, with a yearly incidence of 2.1%. LFTs correlated positively with cholesterol (P < 0.001), BMI (P = 0.004) and type of oestrogen therapy (P = 0.04). Increasing doses of HRT resulted in a significant decrease in GGT, ALT, bilirubin and albumin. No evidence of excessive hepatic autoimmunity was found. CONCLUSION: The prevalence of raised liver enzymes in TS may have been underestimated by the use of reference ranges rather than matched controls. Obesity and hyperlipidaemia are associated with raised LFTs, as well as the use of HRT compared to the oral contraceptive pill (OCP). Exogenous oestrogen both as OCP and HRT improves liver function. Liver dysfunction in TS is likely to be a form of hepatic steatosis and intervention trials are now indicated.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
