Abstract:
Objective To explore the expression significance of serum Kisspeptin and luteinizing hormone(LH)in girls with central precocious puberty(CPP).Methods A total of 98 CPP girls were included as the study group,and 91 healthy girls during the same period were used as the control group.Under the condition of no intervention,CPP girls were followed up for 6 months and assigned into the fast progressive CPP(RP-CPP)group(n=46)and the slowly progressive CPP(SP-CPP)group(n=52)based on their developmental status during the follow-up period.ELISA was applied to detect serum Kisspeptin level.Chemiluminescence method was applied to detect serum LH and follicle stimulating hormone(FSH)levels.The correlation of serum Kisspeptin,LH baseline(B-LH)and growth development and imaging indicators was analyzed.Receiver operating characteristic curve(ROC)was applied to analyze the value of serum Kisspeptin and LH in predicting RP-CPP.Results Compared with the control group,body mass index(BMI),serum levels of Kisspeptin,B-LH,and FSH baseline(B-FSH)were significantly higher in the study group(P＜0.05).Compared with the SP-CPP group,BMI,bone age index(BAI),serum Kisspepti and B-LH levels were higher in the RP-CPP group,and ovarian volume was larger(P＜0.05).Correlation analysis showed that serum Kisspeptin level was positively correlated with BMI,BAI,ovarian and uterine volume of CPP girls(P＜0.05),and serum B-LH level was positively correlated with ovarian and uterine volume of CPP girls(r=0.218,0.381,0.300,P＜0.05).ROC curve showed that the sensitivity and specificity of Kisspeptin combined with B-LH in predicting RP-CPP were 95.65%and 82.69%,respectively.Conclusion Serum Kisspeptin and B-LH levels are higher in CPP girls,and the combined of the two has a high predictive value for RP-CPP,which can provide a certain reference for clinical diagnosis and treatment.
