Many trials have reported that bloodletting therapy is effective when treating chronic urticaria. There are currently no systematic reviews of bloodletting therapy for chronic urticaria.
The aim of this review is to assess the effectiveness and safety of bloodletting therapy for chronic urticaria.
A systematic review and meta-analysis of randomized controlled trials were performed. Disease activity control was assessed as the primary outcome. Response rate, recurrence rate, and adverse events were assessed as secondary outcomes.
Seven studies with 512 participants were included. One trial showed a significant difference between bloodletting therapy plus medicine and medicine alone in disease activity control (MD 0.67; 95% CI 0.03 to 1.31; p=0.04). Six trials (372 participants) showed a significant difference between bloodletting therapy and pharmacological medication in response rate (RR 1.10; 95% CI 0.97-1.26; P =0.15). Two studies (170 participants) showed a significant difference between bloodletting therapy plus pharmacological medication and pharmacological medication in response rate (RR 1.34; 95% CI 1.10-1.63; p=0.003). Two studies (126 participants) reported a statistically significant difference between bloodletting therapy and pharmacological medication in recurrence rate. No serious adverse events related to bloodletting therapy were reported.
Bloodletting therapy might be an effective and safe treatment for chronic urticaria, but the evidence is scarce. More high quality trials are needed in the future.
许多试验报告称,放血疗法在治疗慢性荨麻疹方面有效。目前尚无关于放血疗法治疗慢性荨麻疹的系统评价。
本综述旨在评估放血疗法治疗慢性荨麻疹的有效性和安全性。
对随机对照试验进行系统评价和荟萃分析。疾病活动控制被评估为主要结局。反应率、复发率和不良事件被评估为次要结局。
纳入了 7 项研究,共 512 名参与者。一项试验显示,在疾病活动控制方面,放血疗法联合药物治疗与单独药物治疗之间存在显著差异(MD 0.67;95%CI 0.03 至 1.31;p=0.04)。6 项试验(372 名参与者)显示,在反应率方面,放血疗法与药物治疗之间存在显著差异(RR 1.10;95%CI 0.97-1.26;P =0.15)。两项研究(170 名参与者)显示,在反应率方面,放血疗法联合药物治疗与药物治疗之间存在显著差异(RR 1.34;95%CI 1.10-1.63;p=0.003)。两项研究(126 名参与者)报告了放血疗法与药物治疗在复发率方面的统计学差异。未报告与放血疗法相关的严重不良事件。
放血疗法可能是治疗慢性荨麻疹的一种有效且安全的治疗方法,但证据不足。未来需要更多高质量的试验。
