Purpose:
There is large variation in the clinical manifestations of Clostridium difficile infection (CDI). We also still can not predict which patients are more susceptible to reinfection with CDI. The aim of our study was to evaluate the effect of gene single nucleotide polymorphisms (SNP) of proinflammatory cytokines, specifically IL-1β, IL-8 on the development, clinical course and recurrence of CDI.
Methods:
We performed a prospective study of adults (130 people ≥ 18 years) including 65 patients with CDI treated in tertiary hospital and 65 healthy persons. The following 3 variants were analyzed for the occurrence of gene polymorphisms in patients with CDI versus the control group: IL-1β +3953 A/G (rs1143634), IL-1β -31 A/G (rs1143627), and IL-8 +781 T/C (rs2227306). Then, we assessed the correlation between these genetic polymorphisms and biochemical parameters important in CDI course, CDI severity as well as CDI recurrence.
Results And Conclusions:
The presence of genetic polymorphisms of IL-1β +3953 A/G, -31 A/G and IL-8 +781 T/C did not have an effect on the development or recurrence of CDI. The presence of IL-8 +781 T/C polymorphism is associated with the severe CDI.
