Serum Concentrationsof Leptin and Soluble Leptin Receptor in Women after BilateralOvariectomy
Sérové koncentraceleptinu a solubilního leptinového receptoru u žen po bilaterálníovarektomii
Cíl práce:
Zjistit, zda se mění koncentrace leptinu a solubilního leptinového receptoru (LEPR)v séru žen po bilaterální ovarektomii a zda existuje korelace mezi koncentracemi leptinu a LEPRs koncentracemi LH, FSH, 17 b-estradiolem a BMI před a po kastraci.Typ studie: Prospektivní klinická studie.Název a sídlo pracoviště: Gynekologicko-porodnická klinika 1. LF UK a VFN, Praha.Metodika: Do studie bylo zařazeno 10 normálně menstruujících žen ve fertilním věku. Odběry bylyprovedeny vždy ve folikulární fázi menstruačního cyklu a 5. den po bilaterální ovarektomii. Devíti ženám byla spolu s bilaterální ovarektomií provedena též hysterektomie. Byly stanovenyparametry: leptin, solubilní leptinový receptor, FSH, LH, 17 b-estradiol, BMI. Sérové koncentraceleptinu, solubilního leptinového receptoru byly zjišťovány pomocí komerčních kitů pro enzymoimunoanalýzu – ELISA. Sérové koncentrace FSH, LH a 17 b-estradiolu byly stanoveny pomocíkomerčních kitů pro radioimunoanalýzu.Výsledky: Neprokázali jsme statisticky významné změny v koncentraci leptinu (8,9 ± 5,5 vs 7 ± 5,6)a LEPR (16,2 ± 5,6 vs 20,9 ± 8,9) před a po chirurgické kastraci. Po operaci se podle očekávánívýznamně zvýšila koncentrace FSH a LH a naopak snížila koncentrace 17 b-estradiolu (p

Overview
Objective:
To determine whether the blood concentrations of leptin and soluble leptin receptor(LEPR) hang in women after bilateral ovariectomy, and whether there is a relationship betweenthe concentrations of leptin, LEPR and LH, FSH and 17 b-estradiol before and after castration.Design: Prospective clinical study.Setting: Department of Obstetrics and Gynaecology, First Faculty of Medicine, Charles Universityand the General Faculty Hospital, Prague.Methods: 10 women of reproductive age (31–37 years) with a regular menstrual cycle were inclu-ded in the study. Blood samples were always taken during the follicular phase of the menstrualcycle and 5 days after bilateral ovariectomy. In 9 women, hysterectomy was performed with thebilateral ovariectomy. Evaluated parameters: leptin, soluble leptin receptor, FSH, LH, 17 b-estradiol and BMI. Serum soluble leptin receptor and leptin concentrations were determined usingcommercial ELISA kits. Serum concentrations of FSH, LH, and 17 b-estradiol were determinedusing commercial RIA kits.Results: We did not find any statistically significant changes in the concentration of leptin (8.9 ±5.5 vs 7 ± 5.6) and LEPR (16.2 ± 5.6 vs 20.9 ± 8.9) before and after surgical castration. After surgery,according to expectations, the concentration of LH and FSH significantly increased while theconcentration of 17 b-estradiol decreased (P
