The Cutoff of Gonadotropins for Close Evaluation of Cardiometabolic Risk Factors in Turner Syndrome

Turner syndrome is a common genetic disorder in females. It is a disorder characterized by variable number of clinical features, so it needs a multidisciplinary approach for care. Therefore, we aimed to define the cutoff of gonadotropins for close evaluation of cardiometabolic risk factors in Turner syndrome.

This is a case‑control study on 31 patients with Turner syndrome and 31 healthy individuals. Clinical examination including blood pressure measurement and systems evaluation was performed. Laboratory testing, which included 12‑h fasting, assessed lipid profile, glucose, and serum gonadotropin.

Turner syndrome had a higher BMI, systolic, and diastolic blood pressure than the normal group (P < 0.001) Patients with Turner syndrome had significantly higher total cholesterol, low‑density lipoprotein, triglyceride, and TG‑to‑high‑density lipoprotein ratio compared to the healthy individuals (P < 0.05). With increasing LH and FSH, BMI values, systolic blood pressure, and total cholesterol increased significantly (P < 0.001). Serum TG levels in Turner syndrome were only positively correlated with LH and not correlated with FSH. The cutoff point of LH and FSH for triglyceride in upper 75 percentile were 31 (sensitivity = 38.1%, specificity = 80%) and 48 (sensitivity = 61.9%, specificity = 70%), respectively.

Based on dyslipidemia and lower level of ejection fraction, considering cardiometabolic risk factors in lower age groups in Turner syndrome can be recommended.
