Detailed Description
Obesity and related complications (non-alcoholic fatty liver disease (NAFLD), type 2 diabetes mellitus (DM)) have become an important public health problem. Their prevalence continues to increase worldwide in children. Therefore, estimating potential biomarkers that can cause obesity and related complications can be important in their treatment.
Irisin, a myokine, first described by Boström et al. (5) in 2012, is released into the circulation as a product of Fibronectin type III domain-containing 5 (FNDC5) gene activated by increased expression of peroxisome proliferator-activated receptor-ɣ coactivator-1' (PGC1)-α in the muscle cell along with exercise. The circulating irisin increases the expression of UCP1 mRNA in WAT cells. As a result, WAT cells are converted into BAT cells. Thus, irisin is involved in termogenesis and energy consumption.
Conflicting results have been reported in studies investigating the relationship between irisin level and obesity and related complications. Irisin was thought to play a role in the development of obesity. It has been suggested that it may be an alternative treatment agent for obesity and glucose tolerance. In some studies, irisin levels were found to be higher in obese children and adults than in healthy controls, low in some, and not different in others.
There is limited data in the relevant literature about the relationships between childhood obesity and irisin, as well as between NAFLD and irisin. In our study, we aimed to determine whether serum irisin levels are related to anthropometric measurements and metabolic and biochemical parameters in obese children with and without NAFLD.
Sixty obese pubertal patients (31 girls, 29 boys), aged between 11-18 years, admitted to the pediatric endocrinology outpatient clinic of our hospital wiil be included in the study. These patients will be divided into two groups with and without NAFLD. Patients with another disease or any drug use will be not included in the study. The control group consisted of 28 healthy children (14 girls, 14 boys) who will be similar in age and sex to the obese group.
Physical examination will be done in all children. Body weight (BW) and height will be measured. Body mass index (BMI) values will be compared with BMI curves according to age and gender. BMI≥95.p will be considered as obese. Subcutaneous fat thickness will be measured from the triceps and biceps regions by using a caliper. Waist circumference will be measured in the horizontal plane midway between lowest rib and the iliac crest. Hip circumference will be measured over the widest area of the hips. Waist-to-hip ratio will be calculated.
After one night fasting, two venous serum samples will be taken for irisin levels and biochemical analysis. Glucose, total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), ALT, AST, GGT levels, insulin levels will be determined.
Venous serum samples for the irisin levels will be stored at -80°C until the analysis. Serum irisin levels will be measured.
The homeostasis model assessment of insulin resistance (HOMA-IR) will be calculated using the following formula: fasting insulin level (uIU/ml) x fasting glucose (mg/dl) / 405. A HOMA-IR value >5.22 in males and >3.82 in females will be considered having IR.
Hepatobiliary ultrasound (US) will performed for NAFLD
