Abstract

Objectives: In many laboratories free testosterone can not be measured, so that free androgen index is suggested in-stead. The aim of this study was to compare free androgen index and serum free testosterone levels measured by ra-dioimmunoassay in women with hirsutism or polycystic ovary syndrome. Materials and methods: Totally 94 women referred to the polyclinics of Ankara Numune Hospital were retrospectively included. Three patient groups were composed; 55 of hirsutism, 20 of polycystic ovary syndrome and 19 of both hirsutism and polycystic ovary syndrome. Total testosterone and sex hormone binding globuline levels were measured by chemiluminescence method and free testosterone levels were measured by radioimmunoassay. Free androgen index was calculated from total testosterone and sex hormone binding globuline. Results: There was a significant positive correlation between free testosterone and free androgen index in patients with hirsutism, in patients with polycystic ovary syndrome, in patients with hirsutism and polycystic ovary syndrome, and in total patient group [r(hirsutism)=0,597, r(PCOS)=0,617, r(hirsutism and PCOS)=0,779, r(total patient group)=0,649, P

Abstract

Amaç: Birçok laboratuvarda serbest testosteron ölçümü yapılamadığı için yerine serbest androjen indeksi önerilmiştir. Bu çalışmanın amacı hirsutizmli veya polikistik over sendromlu kadınlarda, serbest androjen indeksi ile radyoimmuno-assay yöntemle ölçülen serbest testosteron düzeylerinin karşılaştırmaktır. Gereç ve yöntem: Retrospektif olarak yapılan çalışmaya, Ankara Numune Eğitim ve Araştırma Hastanesi poliklinikleri-ne başvuran toplam 94 kadın hasta dahil edildi. 55 hirsutizmli, 20 polikistik over sendromlu, 19 hirsutizm ve polikistik over sendromlu üç hasta grubu oluşturuldu. Total testosteron ve seks hormon bağlayıcı globulin düzeyleri kemilümi-nesans yöntemle, serbest testosteron düzeyleri radyoimmunoassay yöntemle çalışıldı. Serbest androjen indeksleri total testosteron ve seks hormon bağlayıcı globulin kullanılarak hesaplandı. Bulgular: ‘Hirsutizmli hastalarda', ‘polikistik over sendromlu hastalarda', ‘hirsutizm ve polikistik over sendromlu hasta-larda' ve ‘toplam hasta grubunda'; serbest testosteron ile serbest androjen indeksi arasında pozitif yönde anlamlı bir ilişki saptandı [r(hirsutizm)=0,597, r(PKOS)=0,617, r(hirsutizm ve PKOS)=0,779, r(toplam hasta grubu)=0,649, P
