Role of polymorphisms rs16944 (-511C/T) of IL1B gene and rs1143634 (+ 3954 C/T) of IL1B gene as genetic predictors of acute pancreatitis

Abstract

Purpose. Identify the role of ONP rs16944 (-511C/T) of the IL1B gene and rs1143634 (+ 3954 C/T) of the IL1B gene in the development of acute pancreatitis. Material and methods. The study involved 296 people diagnosed with acute pancreatitis. There were 124 (41.89%) males and 172 (58.11%) females. By age, patients ranged from 24 to 83 years old, the average age was 44,3±12,6 years. Patients with mild severity OP - 103 (34.79%) people, moderate severity OP - 110 (37.16%) people, severe severity OP - 83 (28.05%) people. The control group amounted to 78 people. Genomic DNA was isolated by sorption method, the carrier of rs16944 (-511C/T) and rs1143634 (+ 3954C/T) of the IL1B gene was determined by real-time polymerase chain reaction using TaqMan allele discrimination technology and commercially available fluorescence probes. Results. Our study revealed a statistically significant increase in the frequency of carriage of the rs16944 (-511C/T) IL1B gene located in the promoter region of the functional polymorphism, which correlates with the severity of acute pancreatitis. It is known that this polymorphism enhances gene expression and leads to an increase in the level of proinflammatory cytokine. On the other hand, there is no correlation between the presence of the structural polymorphism rs1143634 (+ 3954 C/T), localized in exon 5 of the gene IL1B and the development of the disease, as well as the severity. Conclusions. Thus, it can be assumed that in residents of Krasnoyarsk, the carriage of the rs16944 (-511C/T) ONP gene IL1B is a predictor of the development of acute pancreatitis and severe disease, which coincides with the data obtained when compared with the European population of the NCBI base.
