Galectin-1, a recently identified peptide, is primarily released from the adipose tissue. Although galectin-1 was shown to have an anti-inflammatory effect, its specific function is not clearly understood. We aimed to evaluate the relationship of serum galectin-1 levels with clinical and laboratory parameters in childhood obesity. A total of 45 obese children (mean age: 12.1±3.1years) and 35 normal-weight children (mean age: 11.8±2.2years) were enrolled. Clinical [body mass index (BMI), waist circumference (WC), percentage of body fat and blood pressure] and biochemical [glucose, insulin, lipids, galectin-1, high-sensitive C-reactive protein (hsCRP) and leptin levels] parameters were assessed...

There is an increasing need to understand long-term metabolic changes and resultant comorbidities because life expectancy is increasing after pediatric kidney and liver transplants. We evaluated differences in classic and novel cardiometabolic biomarkers among obese and normal weight adolescent transplant recipients. We enrolled a total of 80 adolescent (mean±SD, 14.8 years ±3.0) transplant recipients (63 kidney, 17 liver) with mean duration from transplantation of 6.0 (±4.1) years. Among kidney transplant recipients, overweight and obese individuals had higher leptin (16...

Obesity is the largest and fastest growing public health catastrophe in the world affecting both adults and children with a prevalence impacting more than one-third of United States (US) adult population. Although the long-term solution lies in lifestyle changes in the form of dieting and exercise, intervention is required for those who are already obese. Unfortunately, treatment options remain quite limited due to associated side effects of conventional therapeutics. As a natural alternative, in this study we describe the beneficial effect of a standardized composition (UP603) comprised of extracts from Morus alba, Ilex paraguariensis, and Rosmarinus officinalis in improving metabolic disorders in high fat diet (HFD) and high fat & high fructose diet (HFFD) induced obese C57BL/6J mice...

High blood pressure (BP) in children and adolescents is associated with increased risk of persistent hypertension (HT) in adulthood and, consequently, cardiovascular disease and target organ damage. AIM: The values of selected anthropometric parameters and laboratory test results including leptin and apelin concentration were evaluated with regard to averaged values of office BP measurements and 24-hour ABPM. MATERIAL AND METHODS: The study included 55 children: 23-with primary HT and coexisting overweight or obese (HT-OB), 16-with primary HT and normal weight (HT-NW), and 16 healthy children (C)...

BACKGROUND/OBJECTIVES: Insulin resistance (IR) is the cornerstone of the obesity-associated metabolic derangements observed in obese children. Targeted metabolomics was employed to explore the pathophysiological relevance of hyperinsulinemia in childhood obesity in order to identify biomarkers of IR with potential clinical application. SUBJECTS/METHODS: One hundred prepubertal obese children (50 girls/50 boys, 50% IR and 50% non-IR in each group), underwent an oral glucose tolerance test for usual carbohydrate and lipid metabolism determinations...

CONTEXT: Leptin secreted from adipose tissue signals peripheral energy status to the brain. Monogenic leptin deficiency results in severe early onset obesity with hyperphagia. Recently, a similar phenotype of inactivating leptin mutations but with preserved immunoreactivity and hence normal circulating immunoreactive leptin has been reported. OBJECTIVE: We aimed to evaluate the proportion of bioactive leptin serum levels (compared to immunoreactive leptin) as a biomarker for the screening of leptin gene mutations causing monogenic obesity...

BACKGROUND AND AIMS: Adipokines may play a role in the pathogenesis of the metabolic syndrome (MetS) in children. We aimed to evaluate the association of leptin, adiponectin, and its ratio (L/A ratio) with the metabolic syndrome (MetS) in a subsample of the IDEFICS (Identification and prevention of Dietary- and lifestyle-induced health EFfects In Children and infantS) cohort. METHODS AND RESULTS: Leptin, adiponectin and MetS parameters were measured in a subsample of 1253 children (3-9...

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is strongly associated with childhood obesity, yet the prevalence of obesity is orders of magnitude greater than the prevalence of SCFE. Therefore, it is hypothesized that obesity is not, by itself, a sufficient condition for SCFE, but rather one component of a multifactorial process requiring preexisting physeal pathology. Leptin elevation is seen to varying degrees in patients with obesity, and as leptin has been shown to cause physeal pathology similar to the changes seen in SCFE, we propose that leptin may be a factor distinguishing between patients with SCFE and equally obese children without hip abnormalities...

OBJECTIVES: Increased adiposity increases leptin and decreases adiponectin concentrations, resulting in an increased leptin:adiponectin ratio (LAR). In adults, components of the metabolic syndrome and other cardiometabolic risk factors, what we classify here as "metabolic dysfunction," are associated with both a high LAR and a history of being breast-fed. The relation among breast-feeding, LAR, and degree of metabolic dysfunction in obese youth is unknown. The purpose of our pilot study was to explore this relation and estimate the effect size of the relations to determine the sample size needed to power future prospective studies...

Adenovirus 36 (Ad-36) has recently been suggested as a possible contributor to the current obesity epidemic. The aim of this study was to investigate the prevalence of Ad-36 antibodies in obese children, as well as investigate the role of serum leptin and lipid levels in Ad-36-obesity. Seventy-one obese children and 62 non-obese children were included as the patient group (PG), including the healthy control group (HCG), respectively. Simultaneously, Ad-36 antibodies and adipokine levels were assessed with serum neutralization assays (SNA) and ELISA...

Context: Early-onset obesity, characteristic for disorders affecting the leptin-melanocortin pathway, is also observed in pseudohypoparathyroidism type Ia (PHP1A), a disorder caused by maternal GNAS mutations that disrupt expression or function of the stimulatory G protein (Gsα). Mutations and/or epigenetic abnormalities at the same genetic locus are also the cause of pseudohypoparathyroidism type Ib (PHP1B). However, although equivalent biochemical and radiographic findings can be encountered in these related disorders caused by GNAS abnormalities they are considered distinct clinical entities...

Childhood obesity is a serious public health concern condition, as excess body fat can negatively affect a child's health. Obestatin is a hormone that regulates body weight by suppressing appetite and reducing food intake; fasting obestatin level is negatively correlated with basal insulin level. This study aims to investigate the role of obestatin in insulin resistance. A total of 54 children with simple obesity and 57 healthy controls were recruited. Levels of serum insulin, fasting blood glucose, cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein were measured...

BACKGROUND: Autosomal-recessive proximal spinal muscular atrophies (SMA) are disorders characterized by a ubiquitous deficiency of the survival of motor neuron protein that leads to a multisystemic disorder, which mostly affects alpha motor neurons. Disease progression is clinically associated with failure to thrive or weight loss, mainly caused by chewing and swallowing difficulties. Although pancreatic involvement has been described in animal models, systematic endocrinological evaluation of the energy metabolism in humans is lacking...

Obesity and headache are two highly prevalent diseases both in adults and children and they are associated with a strong personal and social impact. Many studies suggest that obesity is comorbid with headache in general, and migraine in particular and obesity seems to be a risk factor for migraine progression and for migraine frequency both in adults and in children. Research shows that there are multiple areas of overlap between migraine pathophysiology and the central and peripheral pathways regulating feeding: inflammatory mediators such as the calcitonin gene-related protein (CGRP), neurotransmitters such as serotonin, peptides such as orexin and adipocytokines such as adiponectin (ADP) and leptin could explain the common pathogenesis...

Obesity and thyroid function are closely related. Thyroid hormones are involved in the regulation of metabolism, thermogenesis, food intake, and fat oxidation. In obese children the most frequent hormonal abnormalities are slight hyperthyrotropinaemia and moderate increases in total T3 and/or fT3 concentrations. Those abnormalities are usually considered a cause of obesity, but according to recent studies, they should actually be considered an adaptation process aimed at increasing resting energy expenditure and total energy expenditure...

BACKGROUND/OBJECTIVES: The recently identified adipocytokine C1QTNF5 (encodes for CTRP5) has been demonstrated to inhibit pro-metabolic insulin signaling in adipocytes. We hypothesized that adipocyte C1QTNF5 expression in subcutaneous (sc) adipose tissue (AT) would correlate with the degree of obesity, systemic CTRP5 serum levels, and early AT and metabolic dysfunction in children. SUBJECTS/METHODS: Sc AT samples were obtained from 33 healthy Caucasian lean children aged 10...
