Relationship between ghrelin and obestatin levels and ghrelin/obestatin ratio in patients with asthma [Serum ghrelin, obestatin düzeyleri ve ghrelin/obestatin oranının astım ile ilişkisi]

Abstract

Methods: 51 patients with stable persistent asthma and 36 healthy controls were included to the study. Pulmonary function tests were conducted in all case. Skin prick test and an asthma control test were conducted in patients with asthma. All patients and controls were compared in terms of ghrelin and obestatin levels, as well as the ghrelin/obestatin ratio. Plasma concentrations of ghrelin and obestatin were detected by enzymelinked immunosorbent assay. Homeostasis model assessment-insulin resistance (HOMA-IR) scores were calculated as an index of insulin resistance. Results: No differences in ghrelin or obestatin levels or the ghrelin/obestatin ratio were detected between patients with asthma and the control group. Ghrelin levels were significantly lower in obese patients. The HOMA-IR score was significantly higher in patients with asthma than in controls. Conclusion: Ghrelin and obestatin levels, and the ghrelin/obestatin ratio, were similar in controls and patients with stable asthma. Although the groups were similar in terms of body mass index and waist circumference, the HOMA-IR score was significantly higher in patients with asthma. © 2020 by Tuberculosis and Thorax.
