Sex hormone binding globulin and non-protein-bound oestradiol in postmenopausal patients with primary biliary cirrhosis and normal controls.
Several studies have suggested that patients with primary biliary cirrhosis (PBC) have an increased risk of a number of medical conditions related to their oestrogen levels. This study has measured sex hormone binding globulin (SHBG) binding capacity, total oestradiol levels and percentage non-protein-bound (NPB) oestradiol and calculated the concentration of NPB oestradiol, in postmenopausal subjects in the following groups; normal controls, early PBC, advanced PBC and advanced PBC who were receiving therapy. Mean SHBG levels were higher in all groups of patients with PBC than in controls. No significant difference was observed in total or biologically active oestradiol between the four groups.
