Background: Several genetic defects (GHR, SHOX, GHSR, NPR2, IGFALS) have been reported in children classified as ISS. ISS children are GH sufficient and about one third of them show low IGF-I levels, suggesting some degree of GH insensitivity.Objective: To explore potential genetic defects in ISS children suspicious of GH insensitivity, selected by low IGF-I levels and low response to IGF generation test.<...

Background: Human IGF1 gene defects are characterized by intrauterine and postnatal growth retardation, sensorineural deafness, microcephaly and intellectual disability. Seven cases have been reported so far, and the underlying pathophysiology has been characterized in only three.Objective: To describe a patient with severe short stature presenting a novel homozygous IGF1 gene mutation and its underlying pathogenic mechanism.<p clas...

Background: In vitro studies suggest a broader role for aldosterone, beyond elevating blood pressure. Clinical data support the notion that aldosterone can directly alter the function of the immune system and can participate in low-grade inflammation which leads to blood pressure elevation and end organ damage.Objective and hypothesis: To assess in humans, whether aldosterone plasma levels and mineralocorticoid receptor (MR) expression associate...

Background: Paediatric hypertension is increasing and has been associated with obesity and insulin resistance. Recently, cortisol:cortisone ratio and the metalloproteinase 9 (MMP9), which is a marker of vascular remodelling, have been syndicated as new risk factors associated with hypertension.Objective and hypotheses: To analyse the association between paediatric hypertension with clinical, biochemical, inflammation, and vascular remodelling biomarkers<...

An oral GH secretagogue (GHS), LUM-201, stimulates GHSR-1a receptor to enhance endogenous GH pulsatile release. In moderate iPGHD, pulses of GH are found but at reduced levels, resulting in decreased IGF-1 and poor growth. The impact of LUM-201 on GH profiles during treatment of such children has not been reported.Objective: To characterize GH profiles, defined by deconvolution analysis, based on GH concentration in a time series and its...

Background: Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, with an incidence of 1:3000 neonates, and one of the most frequent preventable causes of mental retardation worldwide. Most (65%) cases of primary permanent CH are due to thyroid dysgenesis (TD). However, a genetic cause is identified in less than 5% of CH due to DT.Methods: We performed WES (Whole Exome Sequencing) for siblings with childhood-onset TD and we analy...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...

Background: Compared to children without the disease, children with food allergy are stunted, which is positively correlated with the amount of food eliminated and the duration of the diet.Objective: To compare the effect of an elimination diet on growth between children with cow milk allergy and those who are healthy as control subjects.Subjects and Methods: This study was carried...

Androgen insensitivity syndrome (AIS) is the largest single entity that leads to male under-masculinization. Although adequate serum concentrations of testosterone exclude a defect in testosterone biosynthesis, a low testosterone value at baseline does not always exclude PAIS. Anti-Müllerian hormone (AMH), also called Müllerian inhibiting substance or factor, is secreted in high amounts by the immature Sertoli cell; it is negatively regulated by testosterone.<p c...

Objectives and Study: To compare the bone mineral density (BMD) between children with cow milk protein allergy (CMPA) and those who are healthy as control subjectsMethods: This study was carried out on forty children with cow milk protein allergy attending the Alexandria University Children's Hospital nutrition clinic and compared to forty apparently healthy children of matched age and sex as a control group. Anthro...
