Genetic polymorphisms as predisposing factors of chronic pancreatitis

Abstract

The aim of the work was the study of the polymorphism of a number of genes and their role as predisposing factors in the development of chronic pancreatitis. Materials and methods: A study of genetic polymorphisms in 35 patients with chronic pancreatitis was carried out. Patients were divided into groups. In the experimental group, 8 women and 27 men, whose mean age was 43.2 ± 5.3 years. The control group was made up of hypothetical studies according to generally accepted data for the Caucasoid race. Informed consent to participate in the study was obtained. All patients underwent standard general clinical, biochemical analyzes, as well as human genomic DNA isolated from blood leukocytes was subjected to analysis. Results: It was found that in the experimental group the frequency of gene polymorphism was higher than in the control group. Normal homozygote in the experimental group in the genotype was absent among all genes: MMP1 (-1607delG); 9MMP9 (A-8202G); TIMP-1 (C536T); IL10 (G-1082A); OPG TNFRSF11B- (mutation G1181C); P450 (3A4 CYP3A4 1A / 1B); P-450 (CYP1A1); LPL (Ser447Ter mutation), GSTP1 (mutation Ile105Val). Among heterozygous genes polymorphisms TIMP-1 (C536T), IL10 (G-1082A), LPL (mutation Ser447Ter), P450 (CYP1A1), IL10 (G-1082A) prevailed. The greatest number of pathological homozygotes was detected by MMP1, 9MMP9, P450 (3A4 CYP3A4 1A / 1B), OPG. Conclusions: A study of the genetic polymorphism of the human genome showed that there is a high risk of developing chronic pancreatitis in patients with these polymorphisms (MMP1, 9MMP9, P450 (3A4 CYP3A4 1A / 1B), OPG). Significant differences in the frequency of occurrence of gene mutations in comparison groups were obtained. These polymorphisms are one of the factors predisposing to the development of chronic pancreatitis. The determination of gene polymorphism can be used in surgical practice, including complex diagnosis and predicting the nature of the course of chronic pancreatitis-the development of a cystic form of chronic pancreatitis.
