Abstract

Obesity is often associated with an increased cortisol production and accelerated degradation rate. It is also associated with hyperactivation of the pituitaryadrenal axis. The purpose of this study was to evaluate the activity of pituitaryadrenal axis in normoglysemic obese patients in relation to insulin resistance, ß-cell index. Serum cortisol, ACTH, urinary cortisol levels were analyzed in 36 nondiabetic obese subjects. The study group had a lower insulin sensitivity index HOMA-IR=6.2±3.1 but normal pituitaryadrenal axis activity findings. The correlation analysis showed that there was no correlation between HOMA-IR and serum cortisol, ACTH, urinary cortisol levels. Also there was no correlation between HOMA ß-cell index and pituitaryadrenal axis activity. We thought that pituitaryadrenal axis hyperactivation played a central role for insulin resistance in nondiabetic obese patients. However we couldn't find high levels of adrenal steroids because of accelerated cortisol degradation.

Özet

Obezite, sıklıkla artmış kortizol üretimi ve hızlanmış yıkım hızı ile birliktedir. Aynı zamanda hipofizadrenal aks hiperaktivasyonu da mevcuttur. Bu çalışmanın amacı, normoglisemik obez hastalarda hipofizadrenal aks aktivitesini değerlendirmek ve insulin direnci, ß-hücre indeksi ile ilişkisini araştırmaktır. 36 obez nondiyabetik olgunun serum kortizol, ACTH, üriner kortizol düzeyleri, insulin duyarlılık indeksi (HOMA-IR) ve ß-hücre indeksi analiz edilmiştir.Çalışma grubu olgularda insulin duyarlılığının azaldığı (HOMAIR=6.2±3.1), fakat hipofizadrenal aks ile ilgili bulguların normal sınırlarda olduğu saptandı. Korelasyon analizi, HOMA-IR ile serum kortizol, ACTH, üriner kortizol düzeyleri arasında herhangi bir bağlantı bulunmadığını gösterdi, ß-hücre indeksi ile hipofizadrenal aks aktivitesi arasında da herhangi bir bağlantı yoktu. Normoglisemik obez olgularda insulin direnci gelişiminde, hipofizadrenal aks hiperaktivasyonunun merkezi rol oynadığını düşünüyoruz. Ancak hızlanmış kortizol yıkımı nedeniyle adrenal steroid seviyelerinde yükseklik saptamadık.
