[Meta-analysis of traditional Chinese medicine Jianpi therapy in treatment of atopic dermatitis].

ABSTRACT

To evaluate the clinical efficacy of traditional Chinese medicine Jianpi therapy in the treatment of atopic dermatitis. CNKI, Wanfang knowledge service platform, VIP journal database, Chinese biomedical literature database (CBM), PubMed, the Cochrane Library and EMbase database from inception to December 2017 were searched for the randomized controlled trials (RCTs) on traditional Chinese medicine Jianpi therapy in the treatment of atopic dermatitis. Literature selection and information extraction was completed and screened by two independent reviewers, and then the Cochrane recommended bias risk assessment method was used to evaluate the bias risk, and Review Manager 5.3 was used for the data analysis. Totally 37 clinical RCTs were included in this study, involving 2 973 patients. Analysis results showed that as compared with the western medicine, traditional Chinese medicine Jianpi therapy had higher clinical effective rate, with statistically significant difference (OR=4.05,95%CI[3.27, 5.03],P<0.000 01); the improvement of score was more evident, including SCORAD score (WMD=-9.82,95%CI[-13.31,-6.33],P<0.000 01), EASI score (WMD=-2.80,95%CI[-3.54,-2.07],P<0.000 01), and itching VAS score (WMD=-0.79, 95%CI[-1.10,-0.47],P<0.000 01)；the improvement of serum biochemical levels was more evident,including interferon-γ (IFN-γ) (WMD=1.75,95%CI[1.14,2.35],P<0.000 01), interleukin-4 (IL-4) (WMD=-3.15,95%CI[-4.16,-2.15],P<0.000 01), and Eosinophil direct count (EOS) (WMD=-0.11,95%CI[-0.20,-0.02], P=0.02)；recurrence rate was significantly reduced (OR=0.36,95%CI[0.21,0.60],P<0.000 1); and trial-related adverse events were reported in 11 RCTs. Studies have shown that traditional Chinese medicine Jianpi therapy had significantly higher clinical efficacy than western medicine in the treatment of atopic dermatitis. However, due to the publication bias and low quality bias of included RCTs in this study, more multicenter, high quality, large-sample, randomized double-blind controlled trials are needed to further demonstrate the conclusion.
