ABSTRACT Objective:To evaluate the efficacy and safety of qingkailing injection (QKLI) for acute upper respiratory tract infection (AURTI). Methods:Randomized controlled trials (RCTs) regarding QKLI for the treatment of AURTI were collected through comprehensive searches of many Chinese and English databases and so on. Related RCTs were selected according to the inclusion and exclusion criteria. Then, data were extracted and the methodological quality of included studies were assessed by the Cochrane Collaboration’s tool for assessing risk of bias. Data analysis especially meta analysis was conducted with Review Manager 5.3 software. Results:42 RCTs involving 5 905 patients were included. Meta analysis and subgroup analysis showed,①“QKLI(+western medicine symptomatic treatment, WMST)” compared with “ribavirin(+WMST)” could improve the clinical total effective rate (RR=1.19, 95%CI: 1.16-1.22, P<0.000 01); ②“QKLI(+WMST)” was significantly superior to “antibiotics(+WMST)” in the improvement of clinical total effective rate (RR=1.34, 95%CI:1.25-1.44,P<0.000 01); ③“QKLI+WMST” had an obviously higher clinical total effective rate than “ribavirin+ antibiotics+ WMST” (RR=1.31, 95%CI: 1.23-1.40,P<0.000 01); ④“QKLI(+western medicine routine treatment, WMRT)” was better than “WMRT” in clinical curative effect (RR=1.17, 95%CI: 1.10-1.25, P<0.000 01). Also, QKLI could shorten the duration of the main clinical signs and symptoms (fever, nasal congestion and rhinorrhea, throat discomfort, cough, headache, adenoids). Adverse drug reactions/adverse drug events (ADRs/ADEs) were not mentioned in 19 studies, were not observed in 11 studies and were reported in 12 studies. Among these 12 studies, 11 studies separately reported the occurrence of 21 cases ADRs/ADEs in experimental groups and 34 cases ADRs/ADEs in control groups, one trial merely reported 22 cases ADRs/ADEs in experimental group but did not mentioned the occurrence of ADRs/ADEs in control group.Conclusion:QKLI for the treatment of AURTI could improve the clinical total effective rate and shorten the duration of the main clinical signs and symptoms, however, there was no exact conclusion concluded on safety. |
