Background: Recombinant human GH (rhGH) therapy requires daily s.c. injections, this inconvenient treatment regimen results to poor compliance of the patient. Thus, to improve patient compliance, long-acting rhGH products including various protein fusion techniques have been in development during past 15 years.Objective and hypotheses: In this study, we describe the pharmacokinetics and efficacy of a novel long-acting GH using Fc fusion protein (rhGH-Fc)...

Background: Adolescent hyperandrogenemia is prophase of polycystic ovary syndrome. Obesity is one important cause of hyperandrogenemia. Whether hyperandrogenemia has happened in obese children is need to explore.Aims and objectives: To investigate the levels of insulin and androgens in obese children, analysis the correlation between insulin resistance and androgens, and comparison on the differences of androgens levels between obese boys and girls, and ...

Background: GnRH agonists are a common treatment modality for patients with central precocious puberty.Objective and hypotheses: Danazol-induced precocious puberty rats were used as an animal model to compare the effects of GnRH analogues and to assess combinations of treatment with agonistic and antagonistic GnRH analogues.Method: A 5-day-old female Sprague–Dawley rats were subcutaneously injected with a single dose of 300 &#...

Introduction: Turner syndrome (TS) is caused by monosomy or structural abnormalities of the X chromosome, with a prevalence of out 1/2500 females live birth. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. Here we report a case of a variant TS with breast development.Case report: A 9-year-old girl was referred to our paediatric endocrinology outpatient...

Objective: Prader-Willi syndrome (PWS) is a complex genetic disease associated with hypothalamic-pituitary dysfunction, severe obesity and metabolic dysfunctions. The aim of this study was to describe endocrine and metabolic profiles in PWS children and young adults.We also investigated the differences in clinical outcomes according to genotype.Methods: Data of 64 children and adults with genetically verified PWS aged mo...

Purpose: This study aimed to profile children diagnosed with hypercalcemia of different etiologies at a single center.Method: We retrospectively reviewed 13 children diagnosed with hypercalcemia of different etiologies.Results: We describe 13 pediatric cases, aged 4 months to 12 years old (median age: 8 months), diagnosed from 2018 to 2021. Six males and seven females were included...

Central precocious puberty (CPP) is one of the most common pediatric endocrine diseases with an ever increasing incidence. CPP is associated with the loss of final adult height, early menarche, psychological problems and an increased risk of developing diseases in later adulthood such as female reproductive system tumors. The gonadotropin-releasing hormone stimulation test (GnRHST) is the gold standard for the diagnosis of CPP. However, the test is costly and time consuming to...

Background: The gold standard for CPP diagnosis is gonadotropin releasing hormone stimulation test (GnRHST). However, this test is expensive, invasive and inconvenient for screening. Some recent studies have demonstrated that the FMV urinary luteinizing hormone (U-LH) has a strong correlation with LH peak value and serum basal LH, and a high consistency with Tanner staging results, but due to the lack of large-sample, multicenter clinical research data, a form...

Hypophosphatasia (HPP) is a genetic skeletal disease caused by loss-of-function mutations of ALPL encoding tissue-nonspecific alkaline phosphatase (TNSALP). The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pain, and pathologic fractures. The diagnosis is based on clinical examination, radiographic findings, biochemical parameters of ...

Purpose: Pheochromocytoma (PCC) and paraganglioma (PGL) (PPGL) are rare neuroendocrine tumors, and there is little information on how to treat them in children and adolescents. The objective of this study was to demonstrate the clinical presentation and treatment outcomes in children and adolescents with PPGL in a single Korean tertiary care hospital.Methods: Korean patients diagnosed with PCC and PGL before the age of 2...
