Sex hormone-binding globulin (SHBG) is a serum-protein, that binds testosterone (T) with higher affinity than 17-beta-estradiol (E2). Its elevated serum-levels in liver cirrhosis (LCI) contribute to hypogonadism and feminisation of male patients. However, precondition is an intact steroid-binding. SHBG was enriched from the sera of 23 male LCI-patients, 20 healthy males, 20 hyperthyreot patients and 19 pregnant women by gelfiltration and analysed with a surface plasmon resonance biosensor. The androgen-binding of SHBG could be shown to be fully functional in LCI. When comparing 32 healthy males with 33 LCI-patients, the latter showed a normal total-T, a diminshed free-T and an elevated total-E2. Therefore, modified synthesis, metabolism and central regulation cause a T/E2-imbalance in LCI .By the elevated SHBG with an intact steroid-binding, this imbalance is passed amplified to the biologically active, free hormone-serum-levels and thereby deteriorates the endocrine symptoms.
