Serum nesfatin-1 and leptin levels in non-obese girls with premature thelarche.

Abstract:

AIM:We aimed to investigate serum nesfatin-1 level in girls with premature thelarche (PT) and its relationship with anthropometric parameters and leptin, which are involved in the initiation of pubertal process. SUBJECTS-METHODS:Non-obese girls who presented with the complaint of early (2-8 years) and isolated breast development were included in the study. The control group consisted of age-matched healthy prepubertal girls. Auxological measurements were performed in all subjects. Gonadotropin-releasing hormone (GnRH) stimulation test and bone age assessment were conducted in subjects with early breast development. Girls with a bone age/chronologic age ratio <1.2 and a peak luteinizing hormone (LH) response to GnRH stimulation <5 mIU/L were included in the PT group. RESULTS:The study included 22 non-obese girls with PT and 24 healthy prepubertal controls. Body mass index (BMI), BMI-standard deviation score (SDS) and height SDS were similar between the groups (p > 0.05). Serum leptin and nesfatin-1 levels were found significantly higher in the PT group compared to controls (p < 0.05). No correlation was detected between nesfatin-1 and basal LH, basal follicle stimulating hormone (FSH), stimulated peak LH, peak FSH, leptin levels and anthropometric parameters in the PT group (p > 0.05). CONCLUSION:Results of the present study showed that serum nesfatin-1 and leptin levels are significantly higher in girls with PT than in prepubertal controls. This finding suggests that similar to leptin, nesfatin-1 may also have a central or peripheral role in the initiation of pubertal process and may be related to PT pathogenesis.
