Background: Pseudohypoaldosteronism type I (PHA1) is a rare disease of mineralocorticoid resistance (MR). Neonatal manifestation leads to life-threatening dehydration due to massive salt-loss, acidosis and frequently, failure to thrive. Two clinically and genetically distinct forms exist, namely systemic and renal PHA1 caused by mutations in the subunit genes (SCNN1A, SCNN1B, SCNN1G) of the epithelial sodium channel (ENaC) and mineralocorticoid recep...

Background: Children and adolescents with chronic conditions are at increased risk of secondary osteoporosis. In adult patients, long-term anticoagulation (LTA) including Vitamin K antagonist (VKA) treatment is associated with lower bone mineral density and hip fractures. In children and adolsescent, risk factors for impaired skeletal health and the role of LTA on bone metabolism during the vulnerable phase of linear bone growth remain poorly defined.<p cl...

Introduction: Steroid profiling in children with congenital adrenal hyperplasia (CAH) is used to monitor the balance between androgen and cortisol metabolites and to decide on the optimal glucocorticoid dosage. Twenty-four hour collection is the gold standard for measurement of steroid metabolites in urine, because steroid production follows a circadian rhythm and is influenced by short-term stress and steroid drugs. For some children, e.g. those who were diap...

Background: The course of type 2 diabetes is more severe among children with obesity than among adults. Therefore, children at high risk for glycemic deterioration should be detected early enough to guide preventive (and interventional) clinical management.Methods: We established age- and puberty-specific reference values for 7 different indexes addressing the insulin response during oral glucose tolerance testing upon 4...

Growth hormone deficiency (GHD) in children results in reduced adult height. Children with GHD typically require daily subcutaneous (s.c.) injections of growth hormone (GH). Daily injections are burdensome for both patients and their caregivers and reduced adherence negatively impacts clinical outcomes. Somapacitan (Novo Nordisk) is a long-acting reversible albumin-binding human GH derivative in development for once-weekly s.c. administration in children with GHD, aiming to ov...

Context: Polycystic ovary syndrome (PCOS) is defined by androgen excess and ovarian dysfunction in the absence of a specific physiological diagnosis. The best clinical marker of androgen excess is hirsutism, while the best biochemical parameter is still a matter of debate. Current consensus guidelines recommend serum free testosterone as the most sensitive serum parameter to measure androgen excess. Recently, however, novel active androgens and androgen metabo...

Introduction: Vitamin D status is investigated as a modifier for the risk and course of multiple malignant diseases. Findings point towards a detrimental role of low vitamin D levels for event free and overall survival (EFS/OS). However, vitamin D deficiency is often associated with secondary hyperparathyroidism, which may influence EFS/OS in childhood malignancies.Methods: Real world data from 1547 cases (873 male) of c...

Background: Growth hormone (GH) replacement therapy usually requires daily subcutaneous (s.c.) injections that can be burdensome for patients and their caregivers. Long-acting GH formulations aim to establish a less burdensome dosing regimen that is as safe and efficacious as daily GH to potentially improve adherence and clinical outcomes. Somapacitan, a long-acting reversible albumin-binding GH derivative, is in development for once-weekly s.c. administration...

Introduction: Brain tumors are the most common solid neoplasm in children, and treatment often includes high-dose irradiation of the central nervous system (CNS). Although not universal, growth hormone deficiency (GHD) is a very common endocrine late effect after CNS irradiation in childhood. The consequences of GHD in adults are many e.g., reduced bone mineral density, fatigue, decreased lean body mass and adiposity, which implies that adults with severe GHD ...

Pediatric overweight and obesity are also an issue in children and adolescents with type 1 diabetes (T1D). Body Mass Index (BMI) is an accurate and widely used clinical method for assessing childhood obesity.Objective: To analyze the BMI-standard deviation scores (SDS) in Bulgarian children and adolescents with T1D and its relationship with age, gender, type of insulin treatment, and HbAlc.Materials and Met...
