Evaluation of adipokines in children with cystic fibrosis
Abstract
Introduction: Patients with CF present numerous pathological conditions such as malnutrition, depletion of fat-free mass, metabolic disturbances (abnormal glucose metabolism, increased insulin resistance, chronic energy deficit, local and chronic inflammation), which could affect or be associated with altered adipokines concentration
Material and Methods: We aimed in this study to investigate the levels of selected adipokines such as resistin, apelin, adiponectin to demonstrate their application as possible markers of inflammation.
Results: Serum level of resistin was higher (p < 0.001) and adiponectin - lower (p=0.02) in CF children than in healthy children. There was no difference in serum apelin level between two examined groups. However, values of adiponectin/BMI and apelin/BMI ratios in CF did not differ significantly from controls. Higher values of resistin/BMI ratio in CF in comparison to controls were observed Serum resistin/adiponectin ratio was significantly higher in CF patients than in controls (p < 0.0001). Resistin/BMI ratio correlated negatively with FEV1 (R:-48,p < 0.043). Serum resistin/adiponectin ratio correlated negatively with FEV1/FVC (R:-49, p=0.04), Adipokines showed no correlation with BMI and BMI-SDS, glucose, total cholesterol, and LDL-, HDL-cholesterol, triglyceride serum levels. Spirometric parameters FEV1, FVC, VC correlated negatively with serum glucose levels (R: -0.55, p < 0.018; R: -0.65 p < 0.0025; R:-0.76, p < 0.0008 respectively). FEV1 and FVC correlated positively with BMI-SDS (R:0.58, p < 0.01; R:0.5, p < 0.036, respectively).
Conclusions: A significant increase in resistin concentration expressed also as resistin/BMI, and resistin/adiponectin ratios, observed in children with CF may suggests that this adipokine is involved in the inflammatory process underlying the disease and is related to worse spirometric parameters describing airways obstruction.
