Evaluation Of The Growth Hormone-Insulin like Growth Factor1 Axis And Serum Fibroblast Growth Factor 21 Levels As Related To Stature In Children And Adolescents With Coeliac Disease Adherent To Gluten Free Diet

Kaya Fırat , Urgancı Nafiye , Merve Usta Ayşe , Çelik Sedanur , Uçar Ahmet

Background: Coeliac disease(CD)is a common cause of stunted growth. Despite adherence to gluten-free diet(GFD), short stature may persist in some patients with CD. Studies investigating the growth hormone(GH)-insulin like growth factor-1(IGF1) axis in children and adolescents withCDare scant and inconclusive. Fibroblast growth factor-21(FGF-21)is a181amino acid polypeptide that plays a role in growth, lipid and glucose metabolism. The inhibitory effects of FGF...

A Case with Alstrom Syndrome with a Novel Pathogenic Variant In ALMS1 gene as a Rare Cause of Diabetes Mellitus

Dağdeviren Çakır Aydilek , Gizem Bolaç Özyılmaz Leyla , Uçar Ahmet

Introduction: Alstrom syndrome (ALMS) is an autosomal recessive disorder characterized by multiple organ involvement, including progressive cone-rod dystrophy, sensorineural hearing loss, childhood obesity, and type 2 diabetes mellitus. Pathogenic variants in the ALMS1 gene are the known cause for the occurrence of this devastating condition. Here, we reported a case of Alstrom syndrome with a novel homozygous variant in the ALMS gene, who presented to our cli...

Single Gene Variations in Etiology in Children with Severe Obesity

Kahveci Ahmet , Kelestemur Elif , Kurt Ilknur , Guran Tulay , Turan Serap , Bereket Abdullah , Haliloglu Belma

Background: Obesity is a multifactorial disease caused by environmental and genetic factors. Single gene defects explain approximately 5-13% of early-onset obesity and these rates vary according to genetic panel used and the rate of consanguinity in the population studied. As the new treatment modalities emerge for monogenic obesity, it is important to identify the molecular etiology of obesity.Materials and Methods: Buc...

Keywords: children, primary osteoporosis, next-generation sequencingBackground: Primary osteoporosis (POP) is a rare bone fragility disorder of childhood and is mainly related to osteogenesis imperfecta (OI). However, patients without clinical OI features with recurrent long bone and/or vertebral fractures who comply with the osteoporosis criteria are considered to have non-OI POP. Diagnosis and classification of non-OI ...

Introduction: 5-Hydroxymethylfurfural (HMF) is formed when sugars like glucose and fructose are heated in the presence of amino acids. HMF is naturally present in many foods and we are exposed to HMF in daily life. There are conflicting data on potential genotoxic, mutagenic, carcinogenic, DNA-damaging, organotoxic and enzyme inhibitory effects of HMF and its metabolites. We aimed to investigate toxic effects of HMF on reproductive system in peripubertal rats....

Arasli Yilmaz Aslihan , Elmaogullari Selin , Demirel Fatma , Tayfun Meltem , Ahmet Ucakturk Seyit , Gurbuz Fatih , Kemal Topaloglu Ali

Background: Maturity-Onset Diabetes of the Young (MODY) is a rare monogenic form of diabetes that result in β-cell dysfunction. MODY accounts for 2–5% of all diabetes cases. We presented here a family with MODY2 caused by a novel heterozygous p.L164I (c.490 C>A) mutation of the GCK gene.Case: A 15,5-year-old girl was admitted to our department because of fasting hyperglycemia. She had no polyuria, polydipsia and weight loss...

Macro TSH- a Rare Cause of High Levels of TSH

Elmaogullari Selin , Yilmaz Aslihan Arasli , Ucakturk Seyit Ahmet , Tayfun Meltem , Gurbuz Fatih , Ucar Fatma , Bulut Erdem , Hattori Naoki , Demirel Fatma

Background: Macro TSH is a high molecule weighed complex with low bioactivity that is comprised of TSH and anti-TSH antibodies. Potentiality of macro TSH should be kept in mind in clinically euthyroid and asymptomatic patients with normal free T4 and T3 levels and relatively high TSH levels. Diagnosis of macro TSH is suspected if polyethylene glycol (PEG) precipitable TSH exceeds %75 and confirmed if high molecule weighed TSH is shown with gel filtration ...
