| Popis: | Background The main types of inflammatory bowel diseases (IBD) are ulcerative colitis (UC) and Crohn's disease (CD). There is evidence that, in addition to immunological and environmental factors, genetic factors also play an important role in the pathogenesis of IBD. Determination of polymorphism of CYP2D6 and NAT2 genes encoding I and II phase enzymes of xenobiotic biotransformation may have clinical value as an indicator of individual predisposition to diseases, and also contribute to effective and safe pharmacotherapy. The aim of this study was to investigate the association between genetic polymorphism of CYP2D6 and NAT2 and the incidence of IBD, including UC and CD, among inhabitants of central Poland. Methods The study was performed in 258 individuals from central Poland (115 patients with IBD, including 65 patients with UC and 50 with CD; and in 143 healthy controls). The CYP2D6 genotypes of oxidation and NAT2 genotypes of acetylation were analyzed using the PCR-RFLP method. Results There were no statistically significant differences in the frequency of the CYP2D6 genotypes and alleles in patients with IBD, UC and CD in comparison with the control group. The relative risk (OR) of IBD, UC and CD was higher in carriers of the allele NAT2*7 and was OR = 3.49 ( p = 0.0019), OR = 3.86 ( p = 0.0019), and OR = 3.02 ( p = 0.0247), respectively. Conclusions Polymorphism of the gene encoding CYP2D6 does not affect the incidence of inflammatory bowel diseases. The carriers of the NAT2*7 allele which determines slow acetylation may be more predisposed to inflammatory bowel diseases, including ulcerative colitis and Crohn's disease. |
