Background: Graves’ Disease (GD) is the most common cause of hyperthyroidism in children and develops because of stimulation of the thyroid gland by TSH receptor auto-antibodies (TSHR Ab). An increased risk of obesity has been described in both adults and children following initiation of anti-thyroid drug (ATD) therapy but the longer term impact of GD and it’s treatment on physique in children is unclear.Aims:</strong...

Introduction: Patients with Congenital adrenal hyperplasia (CAH) have increased prevalence of obesity and metabolic problems. The underlining mechanisms are not clearly known. Adipokines are likely involved in this association, however, their role in it is not completely understood.Objective: We studied adiponectin and leptin in children and young persons with CAH, in relation to their body mass, treatment, hormonal and ...

Background: Monitoring disease control in congenital adrenal hyperplasia (CAH) by random serum 17a-Hydroxyprogesterone (17OHP) measurements is invasive and fails to capture total daily adrenal steroid synthesis. Urinary steroid analysis may provide a more suitable, non-invasive method of assessing treatment response in children with CAH, by estimating the total daily excretion of 17OHP metabolites.Method: Urine was colle...

Background: Neonatal vitamin D deficiency (VDD) can result in symptomatic hypocalcemia, seizures and cardiomyopathy and has been associated with reduced bone mineralization in childhood, but is potentially preventable with antenatal cholecalciferol supplementation. Single nucleotide polymorphisms (SNP) in the vitamin D metabolism pathway are associated with serum 25-hydroxyvitamin D [25(OH)D] in adulthood. We assessed whether maternal and/or offspring SNPs in ...

Introduction: Congenital adrenal hyperplasia (CAH) is associated with long-term health problems. However, little is known about co-morbidities and their onset in children and young persons (CYP).Objective: To establish the health status of CYP with CAH across the United Kingdom.Methods: A multi-centre prospective study recruited 102 patients with 21-hydroxylase deficiency targeting...

Introduction: Patients with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) have specific plasma and urinary steroid patterns, with 11-oxygenatedC19 steroids established as key adrenal-specific androgens. Monitoring glucocorticoid (GC) replacement remains a challenge in the absence of reliable biomarkers.Aim: To reassess the urinary steroid profile of children with CAH in relation to plasma ...

Key Words: Congenital Adrenal Hyperplasia, Advanced bone age, Aromatase inhibitors, Predicted Adult HeightIntroduction: Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is characterized by cortisol and mineralocorticoid deficiency with excess adrenal androgen production. Standard treatment includes glucocorticoid and mineralocorticoid replacement. Slightly supraphysiological glucocorticoid r...

Newer studies have indicated that vitamin D has more widespread effects than the classical effects on bone and calcium-phosphate homeostasis. The presence of the vitamin D receptor (VDR) in the testis and male reproductive tract indicates a role for vitamin D in male reproduction. Indeed, vitamin D deficiency and global knock out models of VDR or CYP27B1 in rodents have shown that vitamin D and calcium are important regulators of male reproductive function. Several groups have...

Introduction: Vitamin D deficiency in children is still a global health problem. Measuring free 25-hydroxyvitamin D concentrations could provide a better estimate of the vitamin D status than total 25-hydroxyvitamin D (25(OH)D) levels.Objective: To assess the relationship between measured free vitamin D (m-f25(OH)D) and calculated free 25(OH)D (c-f25(OH)D), total 25(OH)D, intact parathyroid hormone (iPTH) and other markers of phosphocalcic metabolism. Es...

Background: Vitamin D deficiency has a high prevalence in children. It is produced by the skin from exposure to sunlight but its synthesis is influenced by many external and internal factors.Objective and hypotheses: The study aims to evaluate vitamin D in children with different pathology and highlights the influencing factors of it.Method: We evaluate 25-hydroxyvitamin D levels in 84 patients, sex ratio 1.15:1, aged between 3 mon...
