Abstract

Chronic kidney disease (CKD)-associated pruritus is a common adverse symptom in patients with end-stage renal disease treated by dialysis. Herein, a systematic review and meta-analysis of the prevalence of CKD-associated pruritus among adult dialysis patients was conducted.An electronic search of PubMed, Web of Science, Elsevier, Wanfang, and Chinese National Knowledge Infrastructure databases was conducted from inception to November 23, 2016, and all cross-sectional studies that reported the prevalence of CKD-associated pruritus in dialysis were collected. The pooled prevalence was estimated by random-effects model. Potential publication bias was evaluated by the funnel plot as well as Begg and Egger tests.After rigorous screening, a total of 42 studies conducted on 11,800 patients were included in this study. The overall prevalence of CKD-associated pruritus among adult dialysis patients was 55% (95% confidence interval [CI], 49-61, I = 97.6%), the stratification of which was 55% (95% CI, 45-65, I = 94.7%) in men and 55% (95% CI, 46-65, I = 93.3%) in women. In hemodialysis (HD) patients, the prevalence of CKD-associated pruritus was 55% (95% CI, 49-62, I = 97.9%), while in peritoneal dialysis (PD) patients, it was 56% (95% CI, 44-68, I = 89.9%). The prevalence of CKD-associated pruritus for mean dialysis duration <40 months was 56% (95% CI, 48-63, I = 75.1%), while that for mean dialysis duration ≥40 months was 50% (95% CI, 36-64, I = 99.1%).The prevalence of CKD-associated pruritus is high in HD and PD. The prevalence among adult dialysis patients is comparable between China and foreign countries as well as between females and males. Studies with the similar disease definition and analysis of the effects of risk factors on CKD-associated pruritus are needed.
