Long-term efficacy of triptorelin 3-month depot in girls with central precocious puberty.

Purpose: Three-month gonadotropin-releasing hormone agonists (GnRHa) are expected to achieve better compliance in patients with central precocious puberty (CPP). However, 1-month depot remains the dominant choice for conventional treatment worldwide. Our study aimed to investigate the long-term efficacy of a 3-month GnRHa for CPP treatment. Methods: In this retrospective study, 69 Korean girls with CPP were prescribed with either triptorelin pamoate (TP) 3-month depot (n = 29) or triptorelin acetate (TA) 1-month depot (n = 40) and were followed up for 1 year after the end of treatment. Auxological, radiological, and biochemical data were collected every 6 months. Results: Baseline characteristics of the subjects were similar between the two groups. In the TP 3-month depot group, 27/29 (93.1 %) of patients exhibited suppressed LH levels (below 2.5 IU/L) after 6 months of treatment, and this suppression level was reserved until the final injection. The degree of bone age advancement in the TP 3-month depot group decreased from 1.8 ± 0.4 years at the start of treatment to 0.6 ± 0.5 years at 1 year post-treatment. The gain in predicted adult height (PAH) at 1 year after the end of treatment was similar between the TP 3-month and TA 1-month depot groups (5.2 ± 3.1 and 5.3 ± 2.4 cm, respectively; P = 0.875). Conclusion: The 3-month depot of triptorelin effectively inhibited gonadal and sex hormones, suppressed bone maturation, and increased PAH. For the patients' convenience, we suggest a 3-month GnRHa regimen as a promising CPP treatment option.

Weight changes of children in 1 year during COVID-19 pandemic.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has changed everyday life. The Korean government urged schools to close as a measure of social distancing, and children and adolescents seemed to gain weight due to home confinement. We aimed to investigate the trends in weight changes in children during the pandemic period. MATERIALS AND METHODS: This retrospective study included 139 children aged between 6 and 12 years who visited the pediatric endocrine clinic for regular growth follow-up for 1 year during the COVID-19 pandemic. We analyzed changes in the body mass index (BMI), BMI z-score, and proportion of children who were overweight or obese over a period of 1 year. RESULTS: The BMI and BMI z-scores of the 139 children increased significantly over the year. The increase was maximum during the first three months of the COVID-19 pandemic, with little change between the third and sixth month of the pandemic. The proportion of children who were overweight or obese increased over time, from 24.5% at the COVID-19 pandemic baseline to 38.1% 1 year later (p < 0.001). CONCLUSIONS: The COVID-19-related lockdown resulted in significant weight gain in Korean children. Changes in BMI showed different trends depending on the degree of school closure. An overall shift from normal weight to overweight or obesity was observed during the pandemic period.
