PURPOSE: The aim of this study was to evaluate serum levels of leptin, ghrelin, and adiponectin in obese and non-obese children with asthma and in healthy non-asthmatic children, and analyze their relationships with clinical outcomes. METHODS: This study enrolled 40 obese and 51 non-obese children with asthma and 20 healthy children. Body mass index and serum leptin, ghrelin, and adiponectin levels were determined in all children. Asthma symptom scores and lung function test results were recorded for subjects with asthma. RESULTS: Serum leptin levels (11.8+/-7.9, 5.3+/-6.8, and 2.1+/-2.4 ng/mL in the obese asthmatic, non-obese asthmatic, and control groups, respectively) and adiponectin levels (12,586.2+/-3,724.1; 18,089.3+/-6,452.3; and 20,297.5+/-3,680.7 ng/mL, respectively) differed significantly among the groups (P<0.001 for all). Mean ghrelin levels were 196.1+/-96.8 and 311.9+/-352.8 pg/mL in the obese and non-obese asthmatic groups, respectively, and 348.8+/-146.4 pg/mL in the control group (P=0.001). The asthma symptom score was significantly higher in the obese children with asthma than in the non-obese children with asthma (P<0.001). Leptin and adiponectin levels were correlated with the asthma symptom score in non-obese children with asthma (r=0.34 and r=-0.62, respectively). CONCLUSIONS: Obesity leads to more severe asthma symptoms in children. Moreover, leptin, adiponectin, and ghrelin may play important roles in the inflammatory pathogenesis of asthma and obesity co-morbidity.

OBJECTIVES: The purpose of the present study is to emphasize the efficacy of the myocardial performance index and tricuspid annular plane systolic excursion (TAPSE) in the determination of impaired cardiac functions and recovery period following the treatment in children with adenoid and/or tonsillar hypertrophy. METHODS: Fifty-three healthy children after routine laboratory, imaging and clinical examinations, with adenoid and/or tonsillar hypertrophy were evaluated before and 3 months after adenotonsillectomy for cardiac functions using M mode and Doppler echocardiography. RESULTS: The mean age of cases was 6.4±3.0 years, 34 (65%) were male, and 19 (35%) were female. Pulmonary hypertension was observed to be mild in 3 patients and moderate in 1 patient preoperatively. When the preoperative and postoperative echocardiographic measurements of the patients were compared, the tricuspid valve E wave velocity, the E/A ratio (E, early diastolic flow rate; A, late diastolic flow rate), and the TAPSE values were determined to be significantly higher postoperatively (P<0.05). The tricuspid valve deceleration time, the isovolumetric relaxation time and the systolic pulmonary artery pressure were found to be significantly lower compared to the preoperative values (P<0.05). CONCLUSION: Adenoidectomy and/or tonsillectomy may prevent cardiac dysfunctions that can develop in the later periods due to adenoid and/or tonsil hypertrophy in children, before the appearance of the clinical findings of cardiac failure.
