Introduction-Aim: MODY;It is an autosomal dominant, rare type of diabetes that occurs in young people as a result of mutations of beta cell function and genes involved in insulin secretion. The cases may be misdiagnosed as Type1 and Type2 diabetes. Considering that MODY is clinically and genetically heterogeneous, the findings should be evaluated correctly. It is important to define the clinical-laboratory characteristics of diagnosis and follow-up of patients...

Can Increased First Hour Glucose Concentration in OGTT Be a New Indicator in Projecting Metabolic Profile?

Sahin Nursel Muratoglu , Yilmaz Aslihan Arasli , Özalkak Servan , Aycan Zehra

Aim: Recent studies have shown that the first hour glucose concentration of ≥155 mg / dL in the oral glucose tolerance test (OGTT) in adults with normal glucose tolerance (NGT) may be a strong marker for the development of diabetes, and also an increase in subclinical inflammation, insulin resistance, dyslipidemia and serum transaminases. These results indicate that adults with NGT have increased risk of developing cardiovascular disease and non-alcoholi...

Evaluation of the Relationship Between Serum Uric Acid Level and Cardiometabolic Risk in Obese Children and Adolescents

Yilmaz Aslihan Arasli , Sahin Nursel Muratoglu , Bayramoglu Elvan , Özalkak Servan , Erdeve Senay Savas , Çetinkaya Semra , Aycan Zehra

Background: In adult studies, serum uric acid level (SUA) has been shown to be associated with cardiometabolic anomalies of metabolic syndrome such as insulin resistance, hypertension, increased carotid intima thickness, and hyperuricemia is considered as an independent risk factor for atherosclerosis and cardiovascular disease. Early cardiovascular changes in obese children and studies on the relationship between metabolic syndrome and hyperuricemia are quite...

Long-term follow-up in a case with congenital hyperinsulinemic hypoglycemia with a novel p.Ser1389Pro mutation in ABCC8 gene

Introduction: Hyperinsulinemic hypoglycemia is one of the most common causes of severe and persistent hypoglycemia in neonates and children. Early diagnosis and appropriate treatment prevent brain damage due to recurrent hypoglycemia. Genetic examination often can guide the treatment. The most common affected genes are the ABCC8 and KCNJ11 genes, which encode the SUR1 and Kir6.2 KATP channels, respectively. Here, a neonate with a novel variant in AB...

Serum fetuin-A and insulin levels in classic congenital adrenal hyperplasia

Kurnaz Erdal , Çetinkaya Semra , Özalkak Servan , Bayramoglu Elvan , Demirci Gülsah , Öztürk Hasan Serdar , Erdeve Senay Savas , Aycan Zehra

Background: Androgens play a pivotal role in non-reproductive tissues, such as the kidney, heart, and liver, as well as the pancreas. Since the androgen receptor is expressed in pancreas and liver cells, this raises the possibility that excess testosterone results in insulin hypersecretion, and in fetuin-A, a protein produced in the liver. However, whether fetuin-A and insulin levels are affected by androgens in classic congenital adrenal hyperplasia (CAH) due...

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Objective: Congenital Hyperinsulinism(CHI) is a clinically, genetically, and histologically heterogeneous disease. Turkey is a county with highly prevalent cases of severe CHI due to the high rate of consanguinity and recessively inherited KATP gene mutations. We herein evaluated the clinical characteristics, molecular genetic analysis, and follow-up of a large nationwide cohort of CHI from Turkey.Patients and method: Th...
