title: Association of interleukin-1β gene polymorphism and peritonitis in uremic patients undergoing peritoneal dialysis.
abstract: OBJECTIVE
  Interleukin-1 (IL-1) is involved in the disease process of peritonitis. We hypothesize that IL-1 gene polymorphism may have an impact on the occurrence of peritonitis in uremic patients undergoing peritoneal dialysis (PD).
  
  
  METHODS
  Uremic patients were recruited for the study of IL-1β (-511) C/T gene polymorphism in 2002. These patients were then prospectively followed up to monitor their peritoneal membrane characteristics, biochemical parameters, occurrence of peritonitis and patient as well as PD technique survival.
  
  
  RESULTS
  A total of 74 patients were enrolled in the study. During follow-up, at least one episode of peritonitis occurred in 36 patients. Compared with patients without peritonitis, the carriage of C allele in IL-1β gene polymorphism (C/C and C/T genotypes) was significantly associated with the occurrence of peritonitis (p = 0.013). This was further confirmed in the multivariate logistic regression analysis (odds ratio 8.18, p = 0.017).
  
  
  CONCLUSIONS
  Carriers of C allele were associated with an increased risk of peritonitis.
