POLYMORPHISM OF IL-8 CYTOKINE GENE IN PATIENTS WITH PANCREATOGENIC PERITONITIS

Sumy State University, Medical Institute,
Ukraine

Objective. This preliminary study was conducted to assess the possible association of IL-8 (-251À/Ò) polymorphism with clinical course and outcome of acute pancreatitis aggravated by pancreatogenic peritonitis.
Methods. Data for the study were DNA samples, received from the leucocytes of 143 humans: 83 patients with acute pancreatitis aggravated by pancreatogenic peritonitis, 60 healthy blood donors without acute pancreatitis in the anamnesis served as controls. IL-8 (-251À/Ò) polymorphism detection was made with polymerase chain reaction with further length analysis of the restriction fragments.
Results. The analysis of frequency of allelic variants of the cytokine gene IL-8 (-251À/Ò) revealed that genotype A/T was the dominant variant (45%) among healthy blood donors. Distribution of IL-8 (-251À/Ò) polymorphism among the patients with pancreatogenic peritonitis without and after surgical treatment is characterized by dominance of genotype T/T in group after surgical treatment (ð<0.05). This may indicate association of genotype T/T and unfavorable clinical course of pancreatogenic peritonitis (OR>1). Among patients after surgical treatment genotype A/T was less often met in comparison with the group without it (p<0.05). This may indicate the association of genotype A/T and favorable clinical course of pancreatogenic peritonitis (OR<1). Genotype A/A was rarely registered, which may be due to regional peculiarities of the patient’s genotype.
Conclusions. This preliminary study suggests that the identification of genetic polymorphism of IL-8 (-251A/T)
may be informative and serve as an additional criterion to predict both the clinical course and outcome of pancreatogenic peritonitis; it may also specify indications for surgical treatment. However, the possible role of IL-8 (-251A/T) cytokine polymorphism in the outcome of pancreatogenic peritonitis requires further carefully planned cohort investigations.
