| 520 | 3 | |a The concentrations of four immunomodulatory steroids, namely dehydroepiandrosterone (DHEA), its sulfate and its 7-hydroxylated metabolites, and sex hormone-binding globulin (SHBG) and major laboratory parameters of thyroid function were determined in sera from 104 healthy females and 48 males, screened for iodine deficiency in one region of the Czech Republic. The mutual relationships of the laboratory parameters were investigated by using four statistical approaches: correlation analysis, principal component analysis, canonical correlation and linear model relationship. In addition to expected correlations among thyroid parameters and substrate-product relationships among the steroids, several new relationships were revealed: The only thyroid parameter tightly correlating with SHBG was free triiodothyronine. The latter hormone was also associated with one of the 7-OH-DHEA epimers, namely with 7β-OH-DHEA. Thyroid hormones are known to possess thermogenic properties, as does another 7-oxygenated DHEA metabolite, 7-oxo-DHEA, the major metabolite of which is 7β-OH-DHEA. It may indicate a link between the two thermogenic factors. The results should serve for further investigation of changes in the thyroid hormone concentrations, together with SHBG and dehydroepiandrosterone metabolites, under various pathological situations. | |
