    BackgroundThe objective of this systematic review and meta-analysis was to assess the clinical outcomes of Clostridium difficile infection (CDI) in patients with chronic kidney diseases (CKD) and end-stage renal disease (ESRD).MethodsA literature search was performed from inception through February 2015. Studies that reported relative risks, odds ratios or hazard ratios comparing the clinical outcomes of CDI in patients with CKD or ESRD and those without CKD or ESRD were included. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a random-effect, generic inverse variance method.ResultsNineteen studies (a case-control and 18 cohort studies) with 116,875 patients assessing clinical outcomes of CDI were included in the meta-analysis. Pooled RR of severe or complicated CDI in CKD patients was 1.51 (95% CI: 1.00-2.28). The risk of recurrent CDI is significant higher in patients with a pooled RR of 2.73 (95% CI: 1.36-5.47). The pooled RR of mortality risk of CDI in patients with CKD, ESRD and CKD or ESRD were 1.76 (95% CI: 1.26-2.47), 1.58 (1.37-1.83) and 1.76 (1.32-2.34) respectively.ConclusionThis meta-analysis demonstrates poor outcomes of CDI including severe and recurrent CDI in CKD patients. History of CKD and ESRD are both associated with increased mortality risk in patients with CDI.© 2015 John Wiley & Sons Ltd.
