Background
Cognitive dysfunction is a major debilitating co-morbidity of end-stage renal disease, affecting up to 80% of the dialysis population. However, differential effect of hemodialysis (HD) versus peritoneal dialysis (PD) on cognitive dysfunction remains debated.
Methods
We performed a systematic review in different databases including Pubmed, Medline, Embase and Cochrane to identify studies that assessed effect of different dialysis modalities on cognitive functions. Inclusion criteria for our meta-analysis were all studies that compared effect of PD to intermittent HD on cognitive function. Studies were included with reviewing the journal title, year of publication, name of the first author, country of study and the number of enrolees in the PD and HD arms and the methods of assessment of cognitive functions were reported. A fixed effects model was used for the meta-analysis. Publication bias was assessed using a Funnel plot and Galbreith plot analysis.
Results
Out of 200 abstracts reviewed, 11 papers as well as registry studies were identified for this meta-analysis with a total of 219,320 subjects included (Figure 1). Forest plot analysis for the rate of cognitive impairment in different dialysis modalities showed less cognitive impairment in PD population compared to HD patients (Relative Risk = 0.49, 95% Confidence Intervals: 0.46 - 0.52). There was no evidence of heterogeneity in the forest plot analysis (I2 = 0.00%, P = 0.58, Figure 2). Moreover, there was no evidence of publication bias among the studies included (Figure 3 and 4).
Conclusion
Patients on PD show less cognitive dysfunction compared to those on HD.
