Abstract

BACKGROUND/AIMS:

Mounting clinical experience and evidence from scale observational studies have suggested that polycystic kidney disease (PKD) was not a contraindication for peritoneal dialysis (PD). Recent studies have reported that PD may be associated with a better prognosis in PKD than that of non-PKD patients. To solve the problem, we performed a systematic review and comprehensive meta-analysis to compare the outcomes between PKD and non-PKD patients on PD and the all-cause mortality between patients with PKD on PD and hemodialysis (HD).

METHODS:

We conducted a systematic literature using electronic databases (PubMed, Ovid, Embase and Web of Science) to identify the studies reporting the endpoint events of PKD/non-PKD patients with PD and the all-cause mortality between patients with PKD on PD and HD, such as dialysis adequacy, technique failure, PD-related complications, the mode of RRT change, and all-cause mortality. We searched the literature published February 2018 or earlier. We used both fix-effects and random-effects models to calculate the overall effect estimate. A sensitivity analysis and subgroup analysis were performed to find the origin of heterogeneity.

RESULTS:

12 studies with a total of 17,040 patients reported the endpoint events of PKD/non-PKD patients with PD. No significant difference was observed on dialysis adequacy (Kt/V, SMD: -0.02, 95%CI: -0.12-0.08; D: Pcr (4h), SMD: -0.10, 95% CI: -0.26-0.06), technique failure (RR: 0.97, 95%CI: 0.78-1.20), RRT change (RR: 0.96, 95%CI: 0.77-1.19), total PD-associated complications (RR: 1.0, 95%CI: 0.91-1.09) and all-cause mortality (RR: 0.40, 95%CI: 0.33-0.47) in PKD patients, compared with non-PKD subjects undergoing PD. However, the proportion of renal transplantation in PKD patients was higher than that of non-PKD patients (RR: 2.04, 95%CI: 1.88-2.20) with significant heterogeneity (I2 =82.7%, P=0.000). 4 studies with a total of 5,762 patients reported that the all-cause mortality did not differ between the PKD patients on PD and HD (RR: 0.87, 95%CI: 0.72-1.06).

CONCLUSION:

Our meta-analysis found that the outcomes of given population of PKD patients on PD were at least not inferior as compared to those with other primary kidney diseases, and suggested that PKD might be not absolutely a contraindication for PD. Given the limitations of the proposed, it needs further large-scale studies to assess whether PD is a suitable RRT option for end-stage renal disease (ESRD) patients with PKD.
