Metabolism and Axis of Early Menarche Girls and Girls Treated with GnRHa / 中山大学学报(医学科学版)

ABSTRACT

[Objective] We assessed in a retrospective unicenter study the state of metabolism and gonadal axis of early menarche girls and girls who treated with Gonadotropin-releasing hormone analogs (GnRHa).[Methods] Thirty-nine early menarche girls and 58 girls who had been treated with GnRHa were enrolled in our study and 19 normal menarche girls were enrolled as control group.Data were collected in height,weight,gonadal hormone,blood glucose,insulin,blood lipid,leptin,adiponectin and the size of uterus and ovary.[Results] Both BMI SDS for chronological age (CA) and for bone age (BA) of early menarche girls were significantly higher than normal menarche girls (P ＜ 0.05).The ratio of insulin resistance in early menarche girls (20.5％) was also significantly higher than normal girls (0％).No significant difference in lipid metabolism and gonadal axis between two groups.In girls treated with GnRHa,BMISDS,insulin,HOMA-IR and the ratio of insulin resistance (20.7％) were all significantly higher than normal group (P ＜ 0.05).Meanwhile,DHEAS,androstenedione and testosterone of GnRHa treated girls were significantly higher than early menache girls,and DHEAS was higher than normal girls.The size of uterus in treated group was larger than the other two groups.[Conclusion] Early menarche and GnRHa treatment may take negative effect to BMI and glucose metabolism.Androgen was higher in GnRHa treated group.Therefore,suggestion was that BMI,insulin,blood glucose and androgen should be monitored in early menarche girls and girls treated with GnRHa.
