Abstract/OtherAbstract:
The aim of this study was to compare zinc (Zn) metabolism parameters in groups of premenopausal and postmenopausal women with moderate and severe primary arterial hypertension. The study included 38 women, of which 15 were premenopausal and 23 were postmenopausal. Postmenopausal women had a positive correlation between total (ERCt- Zn) and oubain-dependent (ERCos-Zn) rate constants of Zn efflux from lymphocyte (k = 0.52). In premenopausal women's ERCos-Zn was negatively but weakly correlated with serum Zn (Zn-s) (k = 0.35). The Zn ERCt- Zn and ERCos-Zn did not show any correlation with age, as did Zn-s. Lymphocyte Zn correlated negatively with age only in premenopausal women (k = -0.62). The renin-angiotensin-aldosterone system correlated with Zn metabolism parameters. In premenopausal women, plasma renin activity and serum aldosterone showed positive correlations with lymphocyte Zn (Znl) (k = 0.63 and k = 0.41, respectively), and in postmenopausal women, it correlated negatively with Zn-s (k = -0.38) and whole aldosterone correlated negatively with ERCos-Zn (k = -0.41). Positive correlations between Zn metabolism parameters and arterial blood pressure in premenopausal women were as follows: ERCt-Zn with diastolic blood pressure (dRR) (k = 0.40) and ERCos-Zn with dRR (k = 0.47). In postmenopausal women, the correlations between ERC-t-Zn and dRR and systolic blood pressure (sRR) were negative (k = -0.53 and k = -0.63, respectively). A similar situation was observed between dRR and sRR and Zn-s (k = -0.40 and k = -0.38, respectively). The body mass index (BMI) was positively correlated with ERCt-Zn in premenopausal women (k = 0.36), whereas in postmenopausal, it was negatively correlated with ERCos-Zn (k = -0.42). For the whole group, negative correlations were seen between Zns and dRR and sRR (k = -0.36 and k = -0.39, respectively) and between ERCos-Zn and BMI (k = -0.39). The results presented show differences in Zn metabolism in arterial hypertension between premenopausal and postmenopausal women. The role of estrogens in these differences is disscused.
