Objective: Cluster analysis of urinary steroid metabolome analysis obtained by gas chromatography-mass spectrometry (GC-MS) for treatment monitoring of infants with classic salt-wasting CAH. Methods: We evaluated metabolome analysis of spot urine samples of 60 young children ≤4 years of age (29 females) with classic CAH due to 21-hydroxylase deficiency treated with hydrocortisone and fludrocortisone. Subjects were divide...

Background: Severe XX-DSD and ovarian dysgenesis (OD) are the extreme clinical phenotype of approximately 1% of women that are affected by primary ovarian insufficiency (POI). BMP15 and GDF9 are two members of transforming growth factor ß (TGF-β) superfamily; they share an oocyte-specific expression pattern and play a crucial role in early folliculogenesis. Only XX cases of mutations in BMP15 have been proved to cause human disease. Here we describe...

Keywords: short stature, underweight, overweight, obesityIntroduction: Natural growth is an important indicator of health in childhood. Growth retardation can result from systemic and endocrine diseases or poor diet. Being overweight or obese in childhood increases the risk of morbidity and mortality in adulthood. This study, the first of its kind in Morocco, was conducted to compare the prevalence of growth disorders am...

Monogenic autoimmune diabetes results from a single highly penetrant mutation that causes autoimmunity leading to destruction of the beta-cells. Identifying monogenic autoimmune diabetes can be a challenge; early-onset type 1 diabetes (T1D) can cluster with additional autoimmune diseases due to shared polygenic risk, particularly from the HLA DR3 and DR4 alleles, and islet and other organ specific autoantibodies are present in patients with both monogenic and polygenic aetiolo...

Backgrounds: Maturity-onset diabetes of the young (MODY) is a cluster of early-onset, monogenic disorders which is inherited in autosomal dominant form. It is mainly caused by genetic defects in beta-cell, which results in beta-cell dysfunction. Till now, 14 MODY types specified by mutation in respective 14 genes with their etiologies are known. Among them, glucokinase (GCK) gene encodes glucokinase enzyme which plays a crucial role in the regulation of insuli...

Background: Idiopathic hypogonadotropic hypogonadism (IHH) is due to the failure of gonadotrofin releasing hormone (GnRH) secretion which impairs the physiological initiation of puberty. About 30 to 50% of IHH is associated to hereditary causes and about 50 mutated genes have been identified.Objective and methods: We present three intra-familial cases of normosmic IHH (nIHH) related to a new association of two hetero...

Adamantinomatous craniopharyngiomas (ACPs) are clinically challenging tumours, the majority of which have activating mutations in CTNNB1. They are histologically complex, showing solid tumor component comprised of different morphological cell types (e.g. β-catenin accumulating cluster cells and palisading epithelium), surrounded by a florid glial reaction with immune cells, but also a cystic component. ACP cysts often exert substantial mass effect on critical str...

Background: Mutations in the 21-hydroxylase gene (CYP21A2) accounts for 90–95% of all congenital adrenal hyperplasia (CAH) cases. There is a strong relationship between genotype and disease severity.Objective: The aim of the study was to investigate the most frequent known mutations in CYP21A2 and to describe the genotype-phenotype correlation in Turkish children with CAH due to 21-hydroxylase deficiency.Methods: Based on clin...

Objectives: The obesity in population of children and adolescents is one of the biggest public health problems in word today. Early childhood obesity with cluster of metabolic disorders (insulin resistance, impaired glucose tolerance, dyslipidemia and hypertension) are risk factor for cardiovascular morbidly and mortality later in life. Catestatin is a Chromogranin A derived peptide which reduces hepatic/plasma lipids, plasma insulin, improves insulin sensitivity, reduces hype...

Background: Glucocorticoids exert profound immune-modulating effects and regulate the expression of genes involved in cell cycle progression and apoptosis. Synthetic glucocorticoids are the most potent agents used in the treatment of inflammatory, autoimmune and lymphoproliferative disorders. Considerable variation in response to therapeutic doses of glucocorticoids exists among individuals, as evidenced by differences both in disease response and in the incidence of glucocort...
