[Meta-analysis of Kuntai Capsules combined with GnRH-a in treatment of endometriosis].

To systemically evaluate the efficacy and safety of Kuntai Capsules combined with GnRH-a in the treatment of endome-triosis. The databases of CNKI, WanFang, VIP, PubMed, EMbase and Cochrane Library were searched from their establishment to May 2019 to collect the randomized controlled trials of Kuntai Capsules combined with GnRH-a in the treatment of endometriosis. The data were searched, screened and extracted by two researchers according to the inclusion and exclusion criteria, and the data were analyzed by using RevMan 5.3 software. A total of 58 articles were collected and 13 studies were included. The total sample size was 1 041 cases, including 523 cases in the experimental group and 518 cases in the control group. The results of Meta-analysis showed that Kuntai Capsules combined with GnRH-a can reduce the level of follicle stimulating hormone(FSH), luteinizing hormone(LH) and estradiol(E_2) in patients with endometriosis as compared with GnRH-a alone. With a low incidence of adverse events of peri-meno-pausal symptoms during treatment(RR=0.46, 95%CI[0.35, 0.60], P<0.000 01), it can reduce the VAS score of dysmenorrhea(MD=-1.85,95%CI[-1.92,-1.78],P<0.000 01). The recurrence rate in the combined treatment group was lower than that in the control group(RR=0.27, 95%CI[0.09,0.77], P=0.01). This study showed that Kuntai Capsules combined with GnRH-a can reduce the level of FSH, LH and E_2 in patients with endometriosis, reduce the VAS score of dysmenorrhea, with lower incidence of adverse events and recurrence rate, but it still needs large-scale, multicenter, randomized, double-blind and high-quality clinical trials for support and evidence.
