Background: Dialysis patients have impaired host defense mechanisms and frequently require antibiotics for various infective complications. In this study, we investigated whether dialysis patients have greater risk for Clostridium dif?cileassociated diarrhea (CDAD). Methods: During the 4-year study period (2004-2008), 85 patients with CDAD were identi?ed based on a retrospective review of C dif?cile toxin assay or histology records. Nosocomial diarrheal patients without CDAD were considered as controls (n¼403). We assessed the association between renal function and the prevalence and clinical outcomes of CDAD. Results: There was a signi?cant difference in the prevalence rate of chronic kidney disease (CKD) between CDAD and non-CDAD patients (Po0.001). Sixteen patients (18.8%) of the CDAD group were treated with dialysis, whereas 21 patients (5.2%) of the non-CDAD group were treated with dialysis. There was a signi?cant association between renal function and CDAD in patients on dialysis [odds ratio (OR)¼4.44, 95% con?dence interval (CI) 2.19-8.99, Po0.001], but not in patients with CKD stage 3-5 (OR¼1.10, 95% CI 0.63-1.92, P¼0.73). In multivariate analysis, CKD stage 5D was an independent risk factor for the development of CDAD (OR¼13.36, 95% CI 2.94-60.67, P¼0.001). Conclusion: Our data indicate that dialysis patients might be at a greater risk of developing CDAD, which suggests that particular attention should be provided to CDAD when antibiotic treatment is administered to dialysis patients.
