Uremic pruritus (UP) is a chronic disease that can seriously affect the quality of life of dialysis patients. Acupuncture is a non-medication therapy that has been used to treat pruritus disorders. This systematic review aimed to evaluate the efficacy and safety of acupuncture for the treatment of UP. A total of 9 Chinese and English databases were searched from their inception to December 31, 2021, and 214 studies were retrieved. These articles were selected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. The quality of included studies was judged as low to moderate using the Cochrane's risk of bias (RoB) tool V.5.1.0. Finally, 7 randomized controlled trials (n=504) were included in the meta-analysis performed using RevMan V.5.3. Results included effective rate (The effective rate is the percentage of the total number of patients who are clinically cured, reporting treatment to be markedly effective, and reporting treatment to be effective), recurrence rates, and adverse events. Compared with conventional treatment, acupuncture was more effective in treating UP (risk ratio [RR] = 1.28, 95% confidence interval [CI]=1.09 to 1.50, P=0.003). The results were consistent after sensitivity analysis (RR=1.38, 95% CI=1.21 to 1.57, P<0.00001). In subgroup analysis, the efficacy rates of acupuncture and medications (oral and topical) were comparable (RR=1.20, 95% CI= 0.98 to 1.47, P=0.07). Acupuncture combined with hemodialysis was more effective than hemodialysis alone in relieving pruritus (RR = 1.42, 95% CI=1.18 to 1.72, P=0.0002). Adverse events were reported in only three studies, including one case of hyperphosphatemia in the medications group (RR=0.29, 95% CI=0.01 to 7.06, P=0.45). None of the studies reported recurrence rates. In conclusion, acupuncture is a safe treatment modality for patients with UP receiving hemodialysis that can effectively improve UP symptoms, and acupuncture in combination with hemodialysis has more efficacy than hemodialysis alone in improving the UP symptoms.
