Abstract

BACKGROUND: Studies have documented elevated levels of liver enzymes in many females with Turner syndrome (TS). Histology has shown a range of changes. Treatment with female hormone replacement therapy (HRT) reduces liver enzymes. AIM: To study quantitative liver functions in TS in detail with and without HRT. DESIGN: Randomized crossover study with active treatment (HRT in TS and P-pill in controls) or no treatment. SUBJECTS: Women with TS (n = 8, age 29.7 +/- 5.6 (mean +/- s.d.) years), verified by karyotype, and age-matched controls (C; n = 8, age 27.3 +/- 4.9 years). METHODS: We determined liver enzymes in blood, used the galactose elimination capacity to assess hepatocyte cytosol activity, plasma clearance of indocyanine green to assess excretory function, antipyrine clearance to estimate microsomal activity, and the functional hepatic nitrogen clearance (FHNC) to assess mitochondrial-cytosolic metabolic capacity for conversion of amino-nitrogen. RESULTS: Liver enzymes were elevated in untreated TS and reduced by HRT. The hepatic capacities for conversion of galactose, indocyanine green, and antipyrine were normal and did not change by HRT. The FHNC was marginally reduced (untreated TS vs C: 19.4 +/- 5.4 vs 25.2 +/- 7.3 L/h, P = 0.1). FHNC changed slightly with HRT in TS (19.4 +/- 5.4 vs 24.4 +/- 10.2 L/h, P = 0.2). CONCLUSIONS: The elevations of liver enzymes in untreated TS are readily suppressed by HRT. Quantitative liver functions in TS are comparable to controls and are not affected by HRT.

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.
