Abstract (2. Language): 
Serum estradiol (E2), prolactin (PRL), LH, FSH, B2-M, PTH, Ca phosphorus (P) levels and thyroid function tests (TT3, TT4, JT3, JT4 and TSH) were studied. The relationships between hormonal changes and bone metabolic parameters were investigated. Thirty women patients with uremia on maintenance hemodialysis and eighteen healthy subjects as controls were studied. The patients mean age was 39.4 2.9years. Average time on dialysis was 4.6 0.6 years. In the patients serum E2, FSH, TT4, fT4 and Ca levels were significantly lower, serum PRL, B2-M, PTH and P levels were significantly higher than in thi controls (p< 0.001). Serum LH, TT3, fJ3 and TSH le¬vels were not differint between the patient and the controlgroups (p>0.05). There was a close relations¬hip between decreasing serum E2 and increasing se¬rim B2-M, and PTH levels in the patients ( (r= -0.5, p< 0.01; r- -0.6p< 0.01). Hypoestrogenemic women on hemodialysis had high values of bone catabolic pa¬rameters. Hypoestrogenemia might contribute to inc¬rease of bone metabolic changes which were already very accelerated due to secondary hyperparathyroi-dism. Cyclic eastrogen therapy might be necessary for uremic bone disease. Further controlled studies will clarify this study.
Abstract (Original Language): 
Hormonal değişikliklerin üreınik kemik hastalığına etkisini araştırmak amacıyla; ortalama yaşları 38.4 2.9 yıl ve 4.6 0.6 yıldan beri düzenli hemodiyalizde olan 30 bayan hasta ve 18 sağlıklı kişide, serum estradiol (E2), Prolaktin (PRL), LH, FSH, beta 2-Mikroglobulin (B2-M), PTH, Ca, P düzeyleri ve tiroid fonksiyonları (TT3, TT4, fT3, jT4 ve TSH) çalışıldı. Hormonal değişikliklerin, kemik metabolik parametre¬lere etkisi araştırıldı. Hasta grubunda, sberum E2, FSH, TT4, fT4 ve Ca düzeyleri kontrol grubuna oranla önemli derecede dü¬şük, serum PRL, B2-M, PTH ve P değerleri önemli de¬recedeyüksekti (P< 0.01). Serum LH, TT3JT3 ve TSH düzeyleri bakımından gruplar arası fark yoktu (P> 0.05). Hasta grubunda serum E2 düzeyinin azalması ile serum B2-M ve PTH artışı arasında yakın bir ilişki mevcuttu (r= -0.5, p< 0.01; r= -0.6p< 0.001). Hemodiyalizdeki hipoöstrojenemik kadınlar, katabolik kemik parametrelerine sahiptirler. E2 eksikliği, hemo¬diyaliz hastalarında görülen kemik hastalığının olu¬şumunda ve/veya ilerlemesinde etkili olabilir. Hipo-östrojenemik bayan hastalara, klasik tedaviye ilave olarak siklik östrojen tedavisi önerilebilinir. Kapsamlı ve kontrollü çalışmalar, sonuçlarımızı destekleyecek¬tir.
