title: [TNF alfa polymorphism and course of ulcerative colitis].
abstract: Inflammatory bowel diseases including ulcerative colitis are associated with prolonged inflammatory process, that is dependent on cytokine production. Among them crucial role plays tumor necrosis factor TNF-alpha. There is proven association between single nucleotyde polimorphism and ability to produce cytokines.
  
  
  OBJECTIVE
  We analyzed association between TNF-alpha (-308) promoter polymorphism and extension of lesions in ulcerative colitis. TNF-alpha (-308) promoter polymorphism.
  
  
  METHODS
  Analysis was performed using polymerase chain reaction with sequence specific primers method (PCR-SSP) in 48 patients suffering from ulcerative colitis and association between TNF-alpha (-308) promoter polymorphism and ulcerative colitis macroscopic lesions classified according Montreal classification was investigated.
  
  
  RESULTS
  No statistically significant association among groups of patients and TNF-alpha (-308) promoter polymorphism was observed. More cases of TNF-alpha (-308) promoter polymorphism associated with low TNF-alpha production were observed in patients with E2 and E3 lesions according to Montreal classification. CONCLUSIONS. There is no direct association between TNF-alpha (-308) promoter polymorphism and ulcerative colitis macroscopic inflammatory lesions evaluated on basis of Montreal classification. There is statistically irrelevant tendency of more cases of pancolitis in group of patient with TNF-alpha (-308) promoter polymorphism associated with low TNF-alpha production.
