Background: Melanocortin 4 receptor (MC4R) deficiency is the commonest monogenic form of non-syndromic obesity. MC4R is a seven transmembrane G-protein coupled receptor implicated in central regulation of body weight. The loss-of-function mutations in MC4R gene will contribute to early-onset obesity associated with hyperinsulinemia, hyperphagia and “binge eating”. We aim to determine the prevalence of MC4R variants in a Pediatrics...

Evaluation of the Frequency and Time Course of Side Effects Asscociated With Metformin Use In Obese Adolescents As Related to Weight Loss: A Prospective Single-Centre Observational Study

Mısırlı Özdemir Ebru , Dağdeviren Çakır Aydilek , Bilge Özakçe Mehmet , Uçar Ahmet

Background: Metformin is a well-known biguanide approved for treatment of Type2 Diabetes. Metformin is not considered as an anti-obesity drug despite its common off-label use. Currently, there are no data regarding the profile of metformin related gastrointestinal side effects (MRGSE) in obese adolescents.Aim: To identify the frequency and time course of MRGSE in obese adolescents and assess the presence of any associati...

Background: The long-acting growth hormone (LAGH) somatrogon has been found to be as effective and safe as daily somatotropin in the treatment of children with GH deficiency (GHD). Somatrogon administered once weekly has the potential to improve treatment adherence and height prognosis.Objective: We aimed to evaluate the first real-life data on somatrogon therapy, which was launched in Türkiye in October 2023.<p...

A myostatin inhibitory antibody potentiates the positive effects of insulin on the skeletal muscle and bone phenotype of insulin-deficient diabetic female mice

Kalaitzoglou Evangelia , Adatorwovor Reuben , Ray Philip , Keeble Alexander , Fry Christopher , Uppuganti Sasidhar , Nyman Jeffry , Fowlkes John , Clay Bunn R

Background: Type 1 diabetes is associated with deficits in skeletal muscle and bone mass and quality. Inhibition of myostatin, a negative regulator of muscle mass, was explored as a therapeutic modality to improve the muscle and bone phenotype associated with insulin-deficient diabetes.Methods: We investigated whether an inhibitory myostatin antibody in streptozotocin (STZ)-induced diabetes in female mice is protective f...

Background: Rare disease registries provide rich longitudinal data on patients with rare conditions that can be used for research. Those charged with access to data must safeguard the process, but also have a good oversight of the available data to be able to work with researchers to realistically assess whether there will be adequate data available to answer specific research questions. Data access committees would benefit from a pragmatic method of rapidly a...

Background: Impairment of the chromatin remodeling factors ATRX and DAXX and telomeres abnormality play a role in cancer biology, influencing the clinical outcomes. However, their roles in adrenal tumorigenesis require broader investigation.Aim: To evaluate ATRX and DAXX genotype and expression, telomere length, and the alternative lengthening of telomeres (ALT), as well as their clinical significance, in primary adrenoc...

The Impact of Acute Exercise on 12,13-Dihydroxy-9Z-Octadecenoic Acid (12,13-DiHOME) Levels in Male Adolescents with Obesity

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...

A rare cause of acquired von Willebrand factor deficiency: Primary hypothyroidism due to autoimmune thyroiditis

Dağdeviren Çakır Aydilek , Yıldız Yıldırmak Zeynep , Eren Simge , Mısırlı Özdemir Ebru , Özdemir Mustafa , Ucar Ahmet

In children, autoimmune thyroiditis is often diagnosed with signs and symptoms such as goiter, short stature, and constipation. Delayed diagnosis of hypothyroidism may result in atypical signs and symptoms at presentation, depending on the severity of hypothyroidism. Von Willebrand disease (vWD) is the most common bleeding disorder caused by the quantitative or qualitative deficiency of von Willebrand factor (vWF). Acquired vWD (avWD) is a disorder characterized by low levels ...

Introduction: Bone fragility or predisposition to fractures with low-impact energy is a rare but potentially limiting condition. Variations in PLS3 gene are a cause of monogenic osteoporosis due to the alteration of osteoclast and osteocyte function and bone mineralization. It is characterized by early-onset osteoporosis, peripheral fractures, vertebral compression fractures and thoracic kyphosis. Due to its X-linked inheritance, the phenotype is more severe i...

Introduction: Heterozygous loss-of-function mutations in the glucokinase (GCK) gene cause MODY 2. Conversely, homozygous loss-of-function mutations in the same gene give rise to permanent neonatal diabetes mellitus (DM). Previously, two patients diagnosed with DM in adolescence and had homozygous GCK mutations were reported. Variants in these patients have been shown to exhibit inactivated kinetics that are indistinguishable from neonatal ons...
