RESUMEN
This study aims to evaluate the effectiveness and safety of Ningmitai Capsules in the treatment of urinary tract infection.To be specific, articles on the treatment of urinary tract infection with Ningmitai Capsules were retrieved from China National Know-ledge Infrastructure(CNKI), Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, and Web of Science(from establishment to October 2021).Eligible randomized controlled trials(RCTs) were screened out, and ROB and RevMan 5.3 of Cochrane were employed for data integration and Meta-analysis.Finally, 17 articles were included, involving 1 972 cases, with 1 045 in the experimental group and 927 in the control group.The Meta-analysis results are as follows.Ningmitai Capsules combined with conventional antibiotics was superior to sensitive antibiotics alone in the treatment of acute pyelonephritis in aspects of clinical cure rate(RR=1.94, 95%CI[1.58, 2.37], P<0.000 01), reduction in the count of red blood cells in the urine(MD=-3.22, 95%CI[-3.23,-3.21], P<0.000 01), decrease in the count of white blood cells in the urine(MD=-2.34, 95%CI[-2.59,-2.10], P<0.000 01), and time for the disappearance of the symptoms(MD_(time for urinary tract irritation disappeared)=-2.19, 95%CI[-2.69,-1.68], P<0.000 01; MD_(time for waist aches disappeared)=-3.58, 95%CI[-4.20,-2.97], P<0.000 01; MD_(time for heating disappeared)=-0.57, 95%CI[-0.81,-0.33], P<0.000 01).The combination of either cephalosporin or quinolone with Ningmitai Capsules can improve clinical cure rate of acute pyelonephritis(RR_(combined with cephalosporin)=1.94, 95%CI[1.56, 2.42], P<0.000 01; RR_(combined with quinolone)=1.91, 95%CI[1.16, 3.15], P=0.01).The clinical cure rate(RR=1.91, 95%CI[1.47, 2.49], P<0.000 01) of diabetes complicated with urinary tract infection by Ningmitai Capsules was higher than that by quinolones.The clinical cure rate(RR=1.22, 95%CI[1.09, 1.37], P=0.000 5) of non-gonococcal urethritis by Ningmitai Capsules combined with conventional tetracycline and macrolide antibiotics was higher than that by conventional antibiotics.Ningmitai Capsules combined with conventional antibiotics/Ningmitai Capsules alone was superior to conventional antibiotics alone in the treatment of urinary tract infection in terms of the clinical cure rate(RR=1.35, 95%CI[1.17, 1.56], P<0.000 1) and incidence of adverse reactions(RR=0.32, 95%CI[0.15, 0.68], P=0.003), particularly the combination with quinolone antibiotics(RR=1.30, 95%CI[1.04, 1.61], P=0.02).The main adverse reactions were mild gastrointestinal discomfort, nausea, vomiting, and dry mouth.In summary, Ningmitai Capsules combined with conventional sensitive antibiotics/Ningmitai Capsules alone can improve the clinical cure rate of patients with urinary tract infection.Ningmitai Capsules combined with conventional sensitive antibiotics can significantly reduce the time for symptom disappearance of acute pyelonephritis and down-regulate the counts of red and white blood cells in the urine compared with antibiotics alone, and no serious adverse reactions have been found.However, in light of the low proportion of quality eligible articles, experiments with rigorous design, large sample size, and complete outcome in-dexes should be carried out in the future to verify the clinical efficacy and safety of Ningmitai Capsules in the treatment of urinary tract infection.
