Is the 1-hour Post-Load Glucose Level by 75g Oral Glucose Tolerance Test a New Risk Factor in Predicting Atherosclerosis?

Kilinç Suna , Demirtaş Tuna , Atay Zeynep

Background and Objectives: Recent studies demonstrated that a 1-hour post-load plasma glucose (1-h PG) value of ≥155 mg/dL during an oral glucose tolerance test (OGTT) is a new risk factor for predicting atherosclerosis. Herein, we evaluated whether individuals with normal glucose tolerance (NGT), whose 1-h PG is ≥155mg/dl, or with impaired glucose tolerance (IGT) have an increased carotid intima–media thickness (CIMT), as compared with NGT in...

The Effect of Improved Metabolic Risk Factors and Metformin Therapy on Circulating Hepatokines in Obese, Insulin-Resistant Adolescents

Kilinç Suna , Kirankaya Aysegül , Atay Zeynep

Introduction: The molecular mechanisms underlying insulin resistance (IR) is complex and has not been fully elucidated yet. The experimental studies point out the role of liver-derived proteins, called hepatokines.Aims: To compare metabolic parameters and hepatokines levels in obese adolescents and healthy controls and to assess the effect of metformin therapy on plasma hepatokines levels in obese, insulin-resistant adol...

Clinical and Genetic Analysis of Five Patients with Vitamin D-Dependent Rickets Type 1A

Hacıhamdioglu Bulent , Ozgurhan Gamze , Karakaya Zeynep , Keskin Ece

The CYP27B1 gene encodes 25-hydroxyvitamin D-1α-hydroxylase. Mutations of this gene cause vitamin D-dependent rickets type 1A (VDDR-IA, OMIM 264700), which is a rare autosomal recessive disorder. Herein we report five patients with 1α-hydroxylase deficiencies. We studied six patients from three families who diagnosed as 1α-hydroxylase deficiency clinically. All patients had hypocalcemia, hypophosphatemia, hyperphosphatasemia, elevated serum PTH, normal or high v...

The Effect of Subclinical Hypothyroidism (SH) and Treatment of SH with L-T4 on Basal Metabolic Rate in Obese Children: A Prospective Study

Muzafferova Nigar , Bas Serpil , Atay Zeynep , Bereket Abdullah , Turan Serap

Introduction: Subclinical hypothyroidism (SH) is reported up to 20% of obese population and thyroid hormone replacement in these individuals are controversial. In this study, we aimed to determine the effect of thyroid hormones on basal metabolic rate (BMR) in obesity and, thyroid hormone replacement on BMH and weight in obese patients with SH.Method: The study was conducted in 31 obese children (15 of them had subclinical hypothyroidism) admitted to our...

The relationship between sleep time and obesity in childhood

Zeynep Altun Ekin , Bilir Pelin , Ergur Ayca Torel ,

Childhood obesity (CO) is an important risk factor for the development of many chronic metabolic diseases in adulthood. Sleep patterns are known to affect leptin and ghrelin levels in the body. Recent studies using Functional Magnetic Resonance Imaging (fMRI) have shown that insufficient sleep time leads to unhealthy eating behaviors in the brain. The aim of this study is to investigate the association between sleep time in childhood and obesity. Consistent with this associati...

The relationship between acanthosis nigricans and vitamin D in obese children and adolescents

Zeynep Altun Ekin , Ergur Ayca Torel , Bilir Pelin ,

Studies show that vitamin D deficiency can have negative effects on glucose homeostasis, although the mechanism for this is still unclear. The possible mechanism may be related to the presence of vitamin D receptors and their metabolizing enzymes in insulin-sensitive cell types, such as pancreatic cells and adipocytes. The aim of this study is to compare how serum 25- OH D level and HOMA-IR index are related to acanthosis nigricans (AN) and which of them is a better marker for...

The association between physical activity and 25-OH vitamin D levels

Zeynep Altun Ekin , Bilir Pelin , Torel Ergur Ayca

In children and adolescents, vitamin D deficiency negatively affects muscle physiology, exposing them to increased muscle damage and pain, stress fractures, and tendon structures. In addition, free radicals released when the body is exposed to oxidative stress after exercise can cause DNA damage. Vitamin D plays an important role in removing these radicals. The purpose of this study is to investigate the relationship between physical activity and 25- OH vitamin D in obese chil...

THe relationship between sunlight exposure and insulin resistance

Zeynep Altun Ekin , Bilir Pelin , Torel Ergur Ayca

Childhood obesity (CO) is an important risk factor for the development of many chronic metabolic diseases in adulthood. Understanding the mechanisms that promote childhood obesity and eliminating these causes in childhood are critical for later life. One of the major complications of obesity is insulin resistance. The purpose of this study is to investigate the relationship between sunlight exposure and insulin resistance in childhood. Specifically, it examines how the duratio...

Aim: Data on response to GH treatment in the very young children with GH deficiency is scarce. The aim of this study was to evaluate the growth response in such children in a national multicentre study and to analyse the factors affecting the growth response.Materials and methods: In this study, we retrospectively evaluated the files of GH deficiency patients who had started GH treatment between 0–3 years of age who were being followed in 14 differe...

Serum Ghrelin and Neuropeptide Y Concentrations and Their Relationship with Gonadotropins and Anthropometric Parameters in Girls with Idiopathic CEntral Precocious Puberty, Premature Thelarche and Premature Adrenarche

İzel Bizbirlik Zeynep , Kilic Sümeyra , Angin Ahmet , ERSOY Betül

Orexigenic molecules such as ghrelin and neuropeptide Y (NPY) can contribute puberty as directly or indirectly. Our aim is to investigate the changes in the levels of orexigenic peptides ghrelin and neuropeptide Y at the onset of puberty in girls with idiopathic central precocious puberty (ICPP), premature thelarche (PT) and premature adrenarche (PA), and to determine their relationship with gonadotropins and anthropometric parameters.Subjects an...
