Abstract

IL-8 -251T/A polymorphism is associated with susceptibility to acute pancreatitis

We conducted a case-control study to clarify the asso­ciations between inflammatory cytokine, including interleukin (IL)-1b, IL-6, IL-8, and IL-10, polymorphisms and risk of acute pancreatitis. Genotyping analyses of IL-1β+3954 C/T (rs1143634), IL-1β-511 C/T (rs16944), IL-6 -174 G/C (rs1800795), IL-6 -634 C/G (rs1800796), IL-8 -251T/A (rs4073), IL-10 -1082A/G (rs1800896), and IL-10 -819C/T (rs1800871) were conducted using polymerase chain reaction-restriction fragment length of polymorphism. Unconditional logistic regression analysis was utilized to assess the potential association be­tween genotype frequencies and risk of acute pancreatitis. Multivari­ate regression analyses showed that subjects carrying the IL-8 -251 AA genotype had a significantly increased risk of acute pancreatitis, with an adjusted odds ratio (95% confidence interval) of 1.55 (1.02-2.36). However, we found no significant association between IL-1β +3954 C/T, IL-1β -511 C/T, IL-6 -174 G/C, IL-6 -174 G/C, IL-6 -634 C/G, IL-10 -1082A/G, or IL-10 -819C/T polymorphisms and risk of acute pancreatitis. We found that the IL-8 -251T/A polymorphism was associated with a higher susceptibility to acute pancreatitis in a Chinese population.
