General Assessment of Calcium-Phosphorus Metabolism and Vitamin D Levels in Patients with Chronic Pancreatitis and Chronic Obstructive Pulmonary Disease

Abstract

Our attention was drawn to the comorbidity of chronic pancreatitis and chronic obstructive pulmonary disease, namely the features of clinical and pathogenetic links. The article examines metabolism of vitamin D, parathyroid hormone and calcium-phosphorus metabolism in patients with this comorbidity and considering exocrine insufficiency. The results of our own research in this direction are presented. The purpose of the study was to determine the nature of the exocrine pancreatic insufficiency effect on the metabolism of vitamin D, parathyroid hormone and calcium-phosphorus metabolism. Material and methods. The study included 30 patients with exacerbation of chronic pancreatitis and 50 patients with a diagnosis of chronic pancreatitis in the acute stage and chronic obstructive pulmonary disease aged 47-55 years (average age – 52.36±1.83 years). All patients had chronic pancreatitis for more than 10 years. Inclusion criteria was the presence of exocrine pancreatic insufficiency and changes of vitamin D in patients’ metabolism. Patients were hospitalized in the gastroenterology department of the Regional Clinical Hospital, Chernivtsi, Ukraine in connection with exacerbation of chronic pancreatitis. Chronic obstructive pulmonary disease was in stable or unstable remission. Respondents were informed about the study and gave their consent. The control group consisted of 20 healthy individuals. Results and discussion. We revealed a complication of the clinical course in patients with chronic pancreatitis and chronic obstructive pulmonary disease on the background of exocrine pancreatic insufficiency. One of the manifestations was a violation of the metabolism of vitamin D, parathyroid hormone and calcium-phosphorus metabolism. Correlation analysis revealed a positive relationship between levels of exocrine pancreatic insufficiency and serum vitamin D concentration (p <0.05, r = 0.71). There was a strong inverse correlation between the levels of parathyroid hormone and vitamin D (p <0.05, r = - 0.87), and the content of calcium in the serum (p <0.05, r = - 0.74). Conclusion. Comorbidity of chronic pancreatitis and chronic obstructive pulmonary disease causes severe disorders of mineral metabolism and metabolism of vitamin D
