Effect of kallistatin and ghrelin on the formation of endothelial dysfunction in patients with chronic pancreatitis and atherosclerosis

Abstract

Introduction: The article is devoted to the optimization of complex diagnosis of endothelial dysfunction in patients with a combination of chronic pancreatitis and atherosclerosis. The aim: To study the level and effects of kallistatin and ghrelin on the formation of endothelial dysfunction in patients with chronic pancreatitis and atherosclerosis. Materials and methods: 54 patients with chronic pancreatitis were examined. The serum kallistatin level was determined by immunoassay using the Human Serpin A4 ELISA Kit from RayBiotech according to the application method. The serum ghrelin level was determined by immunoassay using the Human/Mouse/Rat Ghrelin Enzyme Immunoassay Kit from RayBiotech. Endothelial dysfunction was determined by the method proposed by D.Celermajer. Results: The study of endothelial-dependent and endothelial-independent vasodilatation is indicative of the presence of a pronounced ndothelial dysfunction in patients with chronic pancreatitis and atherosclerosis, which was manifested by a decrease in their level to 8.7±0.4% and 16.8±0.7%, respectively. The level of kallistatin and ghrelin in patients with chronic pancreatitis and atherosclerosis (15.44 ± 3.97 ng/ml and 276.69 ± 10.06 ng/ml respectively) also confirmed their important role in the formation of еndothelial dysfunction in these patients. Conclusions: The study of ghrelin and kallistatin level in serum can serve as a criterion for determining the severity of chronic pancreatitis and atherosclerosis, the development of endothelial dysfunction, and be a marker for predicting their future course.
