The -2518 A/G MCP-1 polymorphism as a risk factor of inflammatory bowel disease.

UNLABELLED Inflammatory bowel diseases (IBD) are disorders originated from immune disturbances. The AIM OF THE STUDY was to evaluate the association between the -2518 A/G MCP-1 polymorphism and the risk of IBD development. MATERIAL AND METHODS Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Study group consisted of 197 subjects with IBD (120 with ulcerative colitis and 77 with Crohn's disease) as well as 210 healthy controls. RESULTS The presence of the -2518 G/G MCP-1 genotype in the investigated groups seems to be connected with higher risk of inflammatory bowel disease as well as Crohn's disease only (OR 2.26; 95% CI 1.44-3.54 and OR 2.08; 95% CI 1.21-3.46, respectively). CONCLUSIONS Our data showed that the -2518 A/G MCP-1 polymorphism might be associated with the IBD occurrence and might be used as predictive factor of these diseases in a Polish population.
