Efficacy and safety of external application of Traditional Chinese Medicine for the treatment of acute gouty arthritis: a systematic review and Meta-analysis

OBJECTIVE:To evaluate the clinical efficacy and safety of external application of Traditional Chinese Medicine (EATCM) on acute gouty arthritis (AGA).METHODS:Six electronic data bases were retrieved from their inception to march 2017.15 randomized controlled clinical trials (RCTs) were included.The quality of the literatures was assessed according to Cochrane review criteria by using RevMan5.3 software;and related data was counted using Stata14.0 software.RESULTS:There was no significant difference in C-reactiveprotein (CRP) between experimental intervention group and control group [(WMD =1.093,95% C/(-2.514,4.701);P =0.553)].In terms of overall efficacy,the EATCM's treatment group was significantly superior to control group [(OR =3.692;95% CI (2.408,5.661);P <0.001)].The EATCM was better than western medicine treatments or other interventions in reducing the adverse reactions [(OR =0.135;95% CI (0.067,0.274);P < 0.001)].All these funnel plots showed unlikelihood of publishing bias.But due to excessive heterogeneity,the statistical results of serum uric acid and visual analogue scale and CRP between the two groups became uncertain.CONCLUSION:The results indicate that EATCM may have greater overall efficacy with fewer adverse drug reactions,although the evidence is weak owing to the low methodological quality and the small number of the included trials.
