Introduction: Langerhans cell histiocytosis (LCH) is a rare disease that the clinical presentation can vary from the involvement of a single region to widespread multiorgan involvement. The most common central nervous system infiltration is observed in the hypothalamic-pituitary region, which frequently leads to central diabetes insipidus (CDİ) and occasionally to anterior pituitary hormone deficiencies. There is limited data on endocrinological findings,...

Background: Treg cells are characterized by expression of Foxp3 molecule that serve as keys in the maintenance of peripheral tolerance and in controlling the immune response. The exact role of Treg cells in the pathogenesis of CAT has not been recognized yet.Objective and hypotheses: It is suggested that vitamin D is one of the factors that can regulate the function of Treg cells. In this study, the relationship between Treg cells (levels and expression)...

Introduction and Objective: Puberty marks the transition from childhood to adulthood, initiated by the activation of the hypothalamic-pituitary-gonadal axis. Anti-Müllerian hormone (AMH) and inhibin B, both secreted by granulosa cells, play crucial roles in pubertal development and reflecting ovarian reserve. Establishing reference intervals for AMH and inhibin B across different pubertal stages is essential for assessing ovarian function and identifying ...

Objective: Obesity is a multifactorial genetic disorder. Monogenic obesity, explaining 5-13% of early-onset cases, is often associated with hyperphagia and reduced energy expenditure. Syndromic obesity involves additional clinical features such as developmental delay, hypogonadism, and sensorial hearing deficits. This study aims to enhance the understanding and management of patients with syndromic obesity by evaluating their anthropometric, laboratory, and cl...

Carney Complex (CNC) is a rare genetic disorder characterized by multiple endocrine and nonendocrine neoplastic manifestations across various organ systems, primarily driven by mutations in the PRKAR1A gene. The most common clinical effects are on the adrenocortical axis. This study seeks to dissect the clinical heterogeneity observed in CNC patients with PRKAR1A mutations, emphasizing the adrenocortical axis and its impacts on patient outcomes.C...

Objectives: American Thyroid Association (ATA) and European Thyroid Association (ETA) published guidelines about evaluation, treatment and follow-up. Despite these recommendations, published data on this subject is insufficient. This study aims to investigate the outcome of pediatric DTC and factors predicting the response to therapy in pediatric DTC.Methods: Medical records of 46 children diagnosed with DTC, between 200...

Background and Objectives: Recent studies demonstrated that a 1-hour post-load plasma glucose (1-h PG) value of ≥155 mg/dL during an oral glucose tolerance test (OGTT) is a new risk factor for predicting atherosclerosis. Herein, we evaluated whether individuals with normal glucose tolerance (NGT), whose 1-h PG is ≥155mg/dl, or with impaired glucose tolerance (IGT) have an increased carotid intima–media thickness (CIMT), as compared with NGT in...

Introduction: The molecular mechanisms underlying insulin resistance (IR) is complex and has not been fully elucidated yet. The experimental studies point out the role of liver-derived proteins, called hepatokines.Aims: To compare metabolic parameters and hepatokines levels in obese adolescents and healthy controls and to assess the effect of metformin therapy on plasma hepatokines levels in obese, insulin-resistant adol...

The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...
