Tiroit hastalığı olanlarda trigliserit/glikoz indeksi insülin direnci belirteci olarak kullanılabilir mi?

Amaç: İnsülin direnci, tip 2 diyabete giden öncül yolağı oluşturur ve diyabet teşhis edilmeden çok önce mevcuttur. Trigliserit/glikoz (TyG) indeksi, son dönemlerde insülin direncinin taranmasında kullanılan basit, güvenilir, kolay ulaşılabilir, maliyet-etkin bir tarama yöntemidir. Çalışmamızın amacı TyG indeksinin, tiroit hastalığı olan kişilerde insülin direnci belirteci olarak kullanılıp kullanılamayacağını araştırmaktır. Gereç ve Yöntem: Çalışmamız retrospektif olarak, 15.04.2016-15.10.2017 arasında Obezite Polikliniğimize başvuran 1280 hastanın dosyası taranarak yapıldı. Açlık kan şekeri, trigliserit ve TSH düzeyi bakılmış ve TSH düzeyi 0,5-10 mU/ml olan hastalar dâhil edildi. Çalışmaya başlamadan önce Girişimsel Olmayan Etik Kurulu onayı alındı. Hastalarda insülin direncinin varlığı Homeostatic Model Assesment of Insulin Resistance (HOMA-IR) düzeyine göre belirlendi. HOMA-IR≥2,5 olan hastalarda insülin direncinin olduğu, HOMA-IR

Can triglyceride/glucose index be used as a marker of insulin resistance in patients with thyroid disease?

Aim: Insulin resistance is the precursor pathway leading to type 2 diabetes and is present long before diabetes is diagnosed. The triglyceride-glucose index (TyG index) is a simple, reliable, cost-effective screening method that has recently been used for screening insulin resistance. The aim of our study is to evaluate whether TyG index can be used as insulin resistance marker in patients with thyroid disease. Materials and Methods: The registry files of 1280 patients applied to the obesity outpatient clinic between 15.04.2016-15.10.2017 were screened for this retrospective study. 604 patients of whom glucose, triglyceride and TSH levels were recorded in their files and TSH levels were 0.5-10 mU/ml were included in the study. Approval was obtained from Noninvasive Ethics Committee before starting the study. The presence of insulin resistance was determined according to the level of the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR). It was assumed that patients with HOMA-IR≥2.5 had insulin resistance. A Pearson and Spearman correlation analyze was used for the evaluation of the relationship between variables. ROC analysis was used to determine the predictability of TyG index to diagnose insulin resistance and cut-off points. P
