Introduction: Congenital Adrenal Hyperplasia (CAH) is the commonest cause of Disorder of Sex development (DSD). It is a group of autosomal recessive disorders caused by deficiency of enzymes involved in synthesis of cortisol, aldosterone or both. The combination of hypocortisolism, hyperandrogenism and adrenal medullary hypofunction due to the disease and side effects of steroids treatment may make these individuals more prone to develop cardiovascular disorders including impa...

We evaluated growth parameters and endocrine disorders in relation to the quantity of liver iron (LIC) measured by the Ferriscan method and insulin-like growth factor 1 (IGF-I) level in a cohort of adolescents with sickle cell disease (SCD) (n=40) and beta thalassemia major (BTM) (n=52) receiving nearly the same protocol of transfusion and iron chelation therapy since early childhood. Before transfusion, hemoglobin concentration had not been less than 9 g/dl ...

Introduction: Congenital adrenal hyperplasia (CAH) is the underlying diagnosis in most newborns presenting with 46,XX disorders of sex development (DSD). Cytochrome P450 oxidoreductase deficiency (PORD) is a rare form of CAH caused by inactivating mutations in the POR gene. POR is a crucial electron donor to all microsomal type 2 P450 cytochromes (CYPs), including 21-hydroxylase (CYP21A2) and 17alpha-hydroxylase (CYP17A1). The hallmark feature of PORD is combined sex-steroid a...

Background: Angiopoietin-2 is a growth factor involved in the pathophysiology of different vascular and inflammatory diseases such as arteriosclerosis. Carotid or aortic scans provide non-invasive screening tools for assessment of preclinical atherosclerosis in high-risk children.Aim: We assessed serum angiopoietin-2 in children and adolescents with type 1 diabetes mellitus as a potential marker for diabetic vascular complications in relation to glycemic...

Background: Pycnodysostosis is a rare recessive condition with mutation in the cathepsin K gene, causing reduction in bone reabsorption resulting in abnormally dense and fragile bones. Characteristic features include deformity of the skull, maxilla causing craniofacial, dental abnormalities with skeletal changes and short stature. Growth hormone therapy has been attempted in a small group of patients with Pycnodysostosis to promote final adult height, however has not been show...

Background: Diabetic nephropathy is a major microvascular complication of diabetes. It affects 25–35% of diabetic patients diagnosed under the age of 30 years. It is the leading cause of premature death in young diabetic patients.Objective and hypotheses: This study was primary designed to assess the short-term effect (6 months) of allopurinol treatment compared to angiotensin-converting enzyme inhibitor (ACEI) and placebo in type 1 diabetic patient...

Background: Ovotesticular disorder of sex development (OT- DSD) is a very rare disorder characterized by the presence of both ovarian and testicular tissue in the same individual. It has an approximate incidence of less than 1/20 000.The patients usually present with ambiguous genitalia and the majority show a 46,XX karyotype, with absence of the SRY sequence.Objective and hypotheses: The study reports the cytogenetic variability and gonadal histological...

Background: Anti-Mullerian hormone (AMH) is produced by Sertoli cells and signals through two transmembrane receptors (AMHR), specific type II and type I, leading to regression of Mullerian ducts (uterus and fallobian tubes) during fetal male sex differentiation. Mutations of AMH and AMHR-II genes lead to persistence of Mullerian ducts in males. These conditions are transmitted in a recessive autosomal pattern and are symptomatic in 46,XY phenotypic males.<p class="abstext...

Background: Vitamin D deficiency may be associated with increased risk of metabolic syndrome.Objective and hypotheses: We aimed to assess the relation between 25-hydroxyvitamin D (25(OH) D) with the different metabolic syndrome components in overweight and obese subjects.Method: Ninety eight subjects (≥85th percentile for age and sex) recruited from the Diabetes, Endocrine & Metabolic Paediatrics Unit (DEMPU), Cairo Unive...

Background: Growth Hormone (GH) therapy has a positive effect on many parameters including metabolic and physiologic functions as well as its effect on growth. It has also been shown that GH therapy exerts a significant effect on cardiac morphology and function as evidenced by echocardiographic findings.Aim: To investigate left and right ventricle (LV, RV) diastolic function by Tissue Doppler imaging (TDI) in pre-pubertal growth hormone deficient (GHD) c...
