title: Meta-analysis: the dialysis mode and immunological response to hepatitis B virus vaccine in dialysis population.
abstract: BACKGROUND
  Patients on maintenance dialysis typically show a suboptimal immune response to hepatitis B virus vaccine compared with the non-uraemic population. Some authors have claimed that dialysis mode has an impact on the immune response to hepatitis B virus vaccine but consistent information is lacking on this issue.
  
  
  OBJECTIVE
  To evaluate the relationship between dialysis mode and immune response to hepatitis B vaccine in dialysis population by performing a systematic review with a meta-analysis of clinical trials.
  
  
  METHODS
  We used the random effects model of DerSimonian and Laird; sources of heterogeneity in effect estimates were explored by performing sensitivity analyses.
  
  
  RESULTS
  The relative risk of failure to respond to hepatitis B vaccine among patients who underwent maintenance haemodialysis vs. peritoneal dialysis was the end point of interest. We identified 14 clinical trials involving 1211 unique patients on maintenance dialysis. Pooling of study results did not show a significant decreased risk of response to hepatitis B vaccine among haemodialysis patients (overall risk ratio: 1.0, 95% confidence intervals: 0.92-1.1). The P-value was 0.13 for our test of study heterogeneity.
  
  
  CONCLUSIONS
  There is no significant link between dialysis mode and seroresponse to hepatitis B virus vaccine in dialysis population.
