Evaluation of the relationship of leptin, adiponectin and carnitine levels with lung function, asthma severity and BMI in children with asthma

Purpose: The aim of this study is to evaluate the relationship between serum levels of leptin, adiponectin and carnitine with lung function, disease severity and BMI (Body Mass Index) in children with asthma. Materials and methods: 97 Pediatric patients with not in acute attack period bronchial asthma and 40 healthy control subjects were included in the study. Pulmonary function tests were done to all asthma patients with a spirometer. Children with asthma were divided into 3 groups according to GINA criteria, mild intermittent, mild persistent, and moderate persistent, with using symptoms and spirometric parameters according to the severity of airway obstruction. Leptin, total carnitine and adiponectin analyzes were performed from venous blood by ELISA method. Results: Patient group serum leptin values were found to be significantly higher than the control group serum leptin values (p=0.001). Patient group serum total carnitine values were found to be significantly lower than the control group (p=0.001). Moderate persistent group adiponectin and total carnitine values were found to be significantly lower than mild intermittent group (p<0.05). A weak negative correlation was found between leptin and total carnitine, eosinophil, BMI values. A weak negative correlation was found between total carnitine and eosinophil, BMI values. A moderate negative correlation was found between age and leptin, adiponectin, total carnitine values. Conclusions: It suggested that leptin levels increased, adiponectin and total carnitine levels decreased in children with asthma and at the same time the decrease in adiponectin and total carnitine levels may be associated with disease severity. © 2021, Pamukkale University.
