The Crohn’s Disease and Proinflammatory Cytokines


 The aim of the study was to examine the profile of the main proinflammatory cytokines in the serum of patients with Crohn's disease and establish their association with the severity and activity of the disease. A total of 61 patients (29 women (47.5%), 32 men (52.5%) aged from 18 to 40 years (mean age (30.42 ± 2.51) years) with the verified diagnosis of Crohn's disease in the active phase were examined. The control group consisted of 30 virtually healthy people (VHP) of corresponding age. Crohn's disease is characterized by reliable (p<0.05) increase of pro-inflammatory cytokines in blood compared to virtually healthy people: TNF-α – by 4.45 times (p<0.05), IL-1α – by 5.08 times (p<0.05), IL-6 – by 2.16 times (p<0.05), IL-8 – by 2.04 times (p<0.05), and IFN-γ – by 5.30 times (p<0.05), which can be due to the development of the active inflammatory process in the intestine and the systemic reaction of the body. The degree of increase in TNF-α and IFN-γ content, as well as the presence of direct correlations between the Best activity index and the content of these cytokines in the blood of the examined patients, confirm their leading role in the cascade of immune-inflammatory reactions during Crohn's disease.
