Clinical efficacy of leprerelin acetate with different dosage forms in central precocious puberty girls

Objective:To observe the clinical efficacy of different dosage forms of lepraline acetate(LA)in the treatment of girls with central precocious puberty(CPP).Methods:72 CPP girls treated in the Department of Pediatrics of Huai'an First People's Hospital from February 2021 to August 2022 were included as subjects and divided into two groups:3-month LA group(n=34)and 1-month LA group(n=38).Both group girls were treated for 6 months.Serum hormone levels,body mass index(BMI),bone age/chronological age(BA/CA)and pelvic color ultrasound were detected at 0 and 6 months after treatment,and the changes of various indexes were compared before and after treatment.Results:1)There were no significant differences in baseline data between the two groups before treatment(P>0.05).2)After 6 months of treatment,BA/CA decreased,growth rate slowed down,and predicted adult height increased in both groups(P<0.05),but there were no significant differences between groups(P>0.05).3)After 6 months of treatment,there waere no significant differences in luteinizing hormone(LH)inhibition ratio between the 3 month and 1 month dosage groups(P>0.05).After treatment,the peak value of serum LH and FSH,estradiol level,uterine volume,bilateral ovarian volume,maximum follicle diameter and the number of follicles 4mm were significantly decreased in the two groups,but there were no significant differences between the two groups(P>0.05).4)There were no significant differences in the levels of thyroid hormone,fasting blood glucose and triglyceride between the two groups before and after treatment(P>0.05).Total cholesterol levels were increased after treatment(P<0.05),but there was no significant difference between groups(P>0.05).5)No serious adverse reactions occurred during the treatment of the two dosage forms of LA,but the 3-month dosage form of LA reduced the treatment cost and improved the treatment compliance.Conclusion:The short-term efficacy of 3-month LA in the treatment of CPP in girls is similar to that of 1-month LA.The 3-month dosage form LA is a safe,effective,and economical method for the treatment of CPP in girls.
