Comparison of Two Different Gnrh Analogs’ Impact on Final Height in Girls with Early Puberty: Triptorelin Acetate vs. Leuprolide Acetate

Context. GnRHa treatment has been a standard of care in progressive early puberty (EP). Choice of the GnRHa formulation is dependent on the preference of the clinician. Objective. To compare the effects of triptorelin acetate (TA) and leuprolide acetate (LA) on anthropometry in girls with EP. Design. A descriptive observational study. Subjects and Methods. Girls diagnosed with central EP and treated with GnRHa at least for one year were included; treated with TA (n=46) and LA (n=35). First year anthropometric response and final height were evaluated. Results. The mean age at the initiation of GnRHa treatment of girls was 8.5±0.5 years. The ratio of obesity and of overweight was 7.4 and 25.9%, respectively. In both TA and LA groups, anthropometric data of the patients at initiation and at the first year of treatment were similar. Although growth velocity was similar in each group, in LA group height SDS at the first year of the treatment showed a significant decrease (p=0.045), but not in TA group (p=0.317). No significant ΔBMI was observed with treatment. The differences between FH – PAH at initiation (height gain) in TA and LA groups were 2.9±4.7 and 4.0±5.8 cm, respectively (p=.316). Height gain per treatment year was 1.7±3.0 cm. Conclusions. There was a significant decrease in height SDS at the first year of leuprolid treatment, but not in triptorelin. Although these two analogs show similar effects on treatment, a not significant but slightly better benefit in leuprolide was observed.
