Meta analysis of self-blood cavity injection for chronic urticaria

Objective: Evaluate the clinical efficacy and safety of autooceptic injection treatment for chronic urticaria (CU). Method: Computer retrieval of PubMed, CBM, VIP, CNKI, Wanfang database, supplemented by manual retrieval, time from Koku to April 2016, collecting randomized controlled trials of autooceptic injection treatment CU for inclusion in literature extraction and quality assessment of information and the use of Result: With 944 patients in 12 studies, Meta analysis showed that the total effective efficiency of autooceptic injection treatment CU was better than the western drug group and acupuncture group, the autooceptic injection treatment CU's increased probability was better than the western drug group and acupuncture group, and autooceptic injection treated CU's recurrence rate significantly lower than the control group, only 1 study showed that There were adverse reactions during treatment, none of the two studies mentioned any significant adverse reactions. Funnel diagrams show that there may be a bias for inclusion in the study. Conclusion: Self-blood cavity injection efficacy is better than acupuncture or western medicine alone, but the limited sample size included in the study and the low quality of the literature is still to be designed., multicenter and large samples of high-quality clinical randomized controlled studies for further validation.
