Purpose: Vitamin D deficiency (VDD) is very common nowadays in children as well as in adults, probably due to decreased exposure to sunlight. In Korea, the prevalence of VDD was 47% in teenage boys and 65% in teenage girls. However, the optimal dosage regimen for correcting deficiency is unknown. We investigate the change of serum 25(OH) vitamin D concentration according to the treatment dosage and duration in VDD.Methods...

Background and objectives: A positive association between birth weight and BMI among children and adolescents has been shown in many populations. Several studies have indicated that breastfed children have lower risk of childhood obesity. Therefore, the aim of this study was to investigate the BMI trajectory according to birth weight status and protective effect of breastfeeding on overweight/obesity prevalence in children 6 years of age.Methods: A retro...

Background: Noonan syndrome is autosomal dominantly inherited disease with an incidence of 1:1000 to 1:2500 newborns. It is caused by different gene mutations involved in the RAS/MAP kinase signaling pathway in the cells. Phenotype including expression of dysmorphic features and visceral organ affection is variable. Different gene mutations are found in approximately 60–70% of tested patients.Objective and hypotheses: To report mutational analysis i...

Background: Achondroplasia is the most common condition characterized by disproportionate short stature. Patients with achondroplasia progressively fall below normal standards for length and height. GH has been widely used to treat short stature with or without GH deficiency (GHD).Objective and hypotheses: The purpose of the present study was to clarify the effectiveness of GH therapy on short stature in achondroplasia.Method: The ...

Background: Triglyceride and glucose (TyG) index is significantly associated with higher risk of developing type 2 diabetes mellitus (T2DM). The mechanism of the role of TyG index in the development of T2DM is not clear. There are few studies on the relationship between the TyG index and homeostatic model assessment of insulin resistance (HOMA-IR).Aims: To elucidate the role of the TyG index, studies are needed on the association between...

Background: Perturbation of inflammation is critically linked to nutrient metabolic pathways and obesity-associated complications, such as insulin resistance and type 2 diabetes (T2DM). The S100 family of proteins, including S100A8/A9 (calprotectin), have been implicated in disease pathogenesis and investigated as potential markers of inflammation. In adults, increased circulating levels of calprotectin have been reported in obesity-related chronic low-grade i...

Introduction: Deficient anterior pituitary with variable immune deficiency (DAVID) syndrome is a rare condition characterized by symptomatic ACTH deficiency and primary hypogammaglobulinemia, caused by a heterozygous mutation in the NFKB2 gene (MIM#164012) on chromosome 10q24. We report the novel mutation of the NFKB2 gene in a Korean boy presenting with gait disturbance, calf pain, and abnormal thyroid function test.<s...

Context: Acute or chronic metabolic derangement after solid organ transplantation (SOT) can result in endocrine complications. As survival rates following SOT have significantly increased, the occurrence of endocrine complications has also risen.Objective: This study was performed to investigate long-term endocrine complications after SOT in children and adolescents.Methods: This s...

Background: Aspartate transaminase-to-platelet ratio index (APRI) is an easy and useful predictor of hepatic fibrosis in patients with chronic hepatic disease, and it significantly correlates with the degree of hepatic fibrosis in adult patients with non-alcoholic fatty liver disease (NAFLD).Objects: This study aimed to evaluate the use of APRI in assessing the severity of NAFLD in children and adolescents.<p class="...

Background: Recent studies suggest an association between the Klotho protein, sex hormones, and insulin-like growth factor-1 (IGF-1). Particularly, considering the intricate interplay among α-Klotho, sex hormones, and IGF-1 during puberty, investigating α-Klotho levels in patients with central precocious puberty (CPP) could provide a deeper understanding of the significance of this protein.Methods: A total of...
