Sanfu acupoint herbal patching for stable asthma: A systematic review and meta-analysis of randomised controlled trials.

ABSTRACT: Sanfu acupoint herbal patching (SAHP) is extensively used in people with stable asthma in China. However, the evidence available is scarce. This systematic review aims to evaluate the preventive and therapeutic effect and safety of SAHP in people with stable asthma.We searched seven electronic databases for randomised controlled trials (RCTs). The Cochrane risk of bias tool was utilised to evaluate the methodological quality of the included studies and RevMan 5.3 and GRADEpro 3.6.1 were applied to perform data analyses.A total of 34 RCTs involving 3313 participants were included. The overall methodological quality of the trials was of high risk of bias. SAHP plus conventional therapy (CT) decreased the mean frequency (times per year) of asthma exacerbations compared with CT alone (MD: -1.42; 95% CI: -2.19 to -0.65; 7 RCTs), and similar effect was found for SAHP versus sham SAHP (MD: 0.42; 95%CI: 0.26-0.69; 1 RCT). For lung function (including PEF%, FEV1% and FEV1/FVC), SAHP plus CT showed better effect than CT alone, and so did SAHP versus sham SAHP on PEF and PEF%. Adverse effects in the SAHP groups were reported to be mild and well tolerated.SAHP alone or combined with CT appears to be more effective than sham SAHP or CT on reduction of asthma exacerbations, improving lung function, and SAHP seems to be safe. However, the findings should be interpreted with caution due to limitations in trial quality. Further, rigorously designed, large-scale trials are warranted for robust evidence.

Project description:Acupoint herbal patching (AHP), which involves local point stimulation with a herbal medicine patch, has long been used to treat patients with asthma in East Asian countries. However, its evidence is equivocal. This systematic review aims to summarize and critically evaluate the efficacy and safety of AHP for asthma.A literature search was conducted in PubMed, EMBASE, the Cochrane library, and the China National Knowledge Infrastructure for studies published on or before April 2014, which were randomized controlled trials (RCTs) examining AHP therapy by itself or in combination with other treatments in asthma patients. Trials needed to report pulmonary function outcomes to be included in analyses. The risk of bias of included studies was assessed using the Cochrane risk of bias assessment tool. For statistical pooling, risk ratio, mean difference (MD), or standardized MD was calculated with 95% confidence intervals (CIs) in a random-effects model.We ultimately included 16 RCTs with 1287 asthmatic patients in analyses. Treatment with AHP improved forced expiratory volume in 1?second (FEV1) by 13% (MD?=?12.99%, 95% CI 5.17%-20.81%) and asthmatic symptoms by 60% (risk ratio of unchanged or getting worse symptoms with AHP?=?0.4, 95% CI 0.27-0.58) over that observed with placebo. However, evidence is limited due to the heterogeneity and paucity of data. When added to conventional therapies, AHP significantly improved the FEV1/forced vital capacity ratio by 11.6% (95% CI 8.49%-14.79%) and reduced the risk of asthmatic symptoms by 69% (95% CI 0.16-0.58). Compared with conventional medication, AHP significantly improved FEV1 (standardized MD?=?0.46, 95% CI 0.05-0.87), but a substantial heterogeneity was detected (I?2=?53%). When added to Chinese herbal medicine, there were no additional benefits of AHP on pulmonary function or global symptom improvement. No serious adverse events were associated with AHP.Evidence for AHP efficacy is encouraging, but not conclusive, because of clinical diversity and the high risk of bias in the examined studies. Further clinical and basic research is needed to determine the role of AHP in lung function and symptom improvement in patients with asthma.

Project description:ObjectivesTo provide a broad evaluation of the efficacy and safety of oral Chinese herbal medicine (CHM) as an adjunctive treatment for diabetic kidney disease (DKD), including mortality, progression to end-stage kidney disease (ESKD), albuminuria, proteinuria and kidney function.DesignA systematic review and meta-analysis.MethodsRandomised controlled trials (RCTs) comparing oral CHM with placebo as an additional intervention to conventional treatments were retrieved from five English (Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Allied and Complementary Medicine Database and Cumulative Index of Nursing and Allied Health Literature) and four Chinese databases (China BioMedical Literature, China National Knowledge Infrastructure, Chonqing VIP and Wanfang) from inception to May 2018. RCTs recruiting adult DKD patients induced by primary diabetes were considered eligible, regardless of the form and ingredients of oral CHM. Mean difference (MD) or standardised mean difference (SMD) was used to analyse continuous variables and RR for dichotomous data.ResultsFrom 7255 reports retrieved, 20 eligible studies involving 2719 DKD patients were included. CHM was associated with greater reduction of albuminuria than placebo, regardless of whether renin-angiotensin system (RAS) inhibitors were concurrently administered (SMD -0.56, 95% CI [-1.04 to -0.08], I2=64%, p=0.002) or not (SMD -0.92, 95% CI [-1.35 to -0.51], I2=87%, p<0.0001). When CHM was used as an adjunct to RAS inhibitors, estimated glomerular filtration rate was higher in the CHM than placebo group (MD 6.28 mL/min; 95% CI [2.42 to 10.14], I2=0%, p=0.001). The effects of CHM on progression to ESKD and mortality were uncertain due to low event rates. The reported adverse events in CHM group included digestive disorders, elevated liver enzyme level, infection, anaemia, hypertension and subarachnoid haemorrhage, but the report rates were low and similar to control groups. The favourable results of CHM should be balanced with the limitations of the included studies such as high heterogeneity, short follow-up periods, small numbers of clinical events and older patients with less advanced disease.ConclusionsBased on moderate to low quality evidence, CHM may have beneficial effects on renal function and albuminuria beyond that afforded by conventional treatment in adults with DKD. Further well-conducted, adequately powered trials with representative DKD populations are warranted to confirm the long-term effect of CHM, particularly on clinically relevant outcomes.Prospero registration numberCRD42015029293.

Project description:OBJECTIVE:Randomised controlled trials (RCT) are the gold standard to provide unbiased data. However, when patients have a treatment preference, randomisation may influence participation and outcomes (eg, external and internal validity). The aim of this study was to assess the influence of patients' preference in RCTs by analysing partially randomised patient preference trials (RPPT); an RCT and preference cohort combined. DESIGN:Systematic review and meta-analyses. DATA SOURCES:MEDLINE, Embase, PsycINFO and the Cochrane Library. ELIGIBILITY CRITERIA FOR SELECTING STUDIES:RPPTs published between January 2005 and October 2018 reporting on allocation of patients to randomised and preference cohorts were included. DATA EXTRACTION AND SYNTHESIS:Two independent reviewers extracted data. The main outcomes were the difference in external validity (participation and baseline characteristics) and internal validity (lost to follow-up, crossover and the primary outcome) between the randomised and the preference cohort within each RPPT, compared in a meta-regression using a Wald test. Risk of bias was not assessed, as no quality assessment for RPPTs has yet been developed. RESULTS:In total, 117 of 3734 identified articles met screening criteria and 44 were eligible (24 873 patients). The participation rate in RPPTs was >95% in 14 trials (range: 48%-100%) and the randomisation refusal rate was >50% in 26 trials (range: 19%-99%). Higher education, female, older age, race and prior experience with one treatment arm were characteristics of patients declining randomisation. The lost to follow-up and cross-over rate were significantly higher in the randomised cohort compared with the preference cohort. Following the meta-analysis, the reported primary outcomes were comparable between both cohorts of the RPPTs, mean difference 0.093 (95% CI -0.178 to 0.364, p=0.502). CONCLUSIONS:Patients' preference led to a substantial proportion of a specific patient group refusing randomisation, while it did not influence the primary outcome within an RPPT. Therefore, RPPTs could increase external validity without compromising the internal validity compared with RCTs. PROSPERO REGISTRATION NUMBER:CRD42019094438.

Project description:BackgroundProkinetic is the first-line conventional treatment for functional dyspepsia (FD) in Asia despite potential adverse events. Chinese herbal medicine (CHM) may be an effective and safe substitution. This network meta-analysis (NMA) aimed to evaluate the comparative effectiveness of different CHM formulae for FD against prokinetics.MethodsSeven international and Chinese databases were searched from their inception to July 2020 for randomised controlled trials (RCTs) on CHM versus prokinetics. Data from each RCT were first pooled using random-effect pairwise meta-analyses and illustrated as risk difference (RD) or standardised mean difference (SMD) with 95% confidence interval (CI). Random-effect NMAs were then performed to evaluate the comparative effectiveness of CHM formulae and displayed as RD with 95% CI or SMD with 95% credible interval (CrI). The GRADE partially contextualised framework was applied for NMA result interpretation.ResultsTwenty-six unique CHM formulae were identified from twenty-eight RCTs of mediocre quality. Pairwise meta-analyses indicated that CHM was superior to prokinetics in alleviating global symptoms at 4-week follow-up (pooled RD: 0.14; 95% CI: 0.10-0.19), even after trim and fill adjustment for publication bias. NMAs demonstrated that Modified Zhi Zhu Decoction may have a moderate beneficial effect on alleviating global symptoms at 4-week follow-up (RD: 0.28; 95% CI: - 0.03 to 0.75). Xiao Pi Kuan Wei Decoction may have a large beneficial effect on alleviating postprandial fullness (SMD: - 2.14; 95% CI: - 2.76 to 0.70), early satiety (SMD: - 3.90; 95% CI: - 0.68 to - 0.42), and epigastric pain (SMD: - 1.23; 95% CI: - 1.66 to - 0.29). No serious adverse events were reported.ConclusionModified Zhi Zhu Decoction and Xiao Pi Kuan Wei Decoction may be considered as an alternative for patients unresponsive to prokinetics. Confirmatory head-to-head trials should be conducted to investigate their comparative effectiveness against prokinetics.

Project description:ObjectiveTo summarise the effects of herbal medications for the prevention of anxiety, depression, pain, and postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic, obstetrical/gynaecological or cardiovascular surgical procedures.MethodsSearches of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and LILACS up until January 2018 were performed to identify randomised controlled trials (RCTs). We included RCTs or quasi-RCTs evaluating any herbal medication among adults undergoing laparoscopic, obstetrical/gynaecological or cardiovascular surgeries. The primary outcomes were anxiety, depression, pain and PONV. We used the Grading of Recommendations Assessment, Development and Evaluation approach to rate overall certainty of the evidence for each outcome.ResultsEleven trials including 693 patients were eligible. Results from three RCTs suggested a statistically significant reduction in vomiting (relative risk/risk?ratio (RR) 0.57; 95% CI 0.38 to 0.86) and nausea (RR 0.69; 95%?CI 0.50 to 0.96) with the use of Zingiber officinale (ginger) compared with placebo in both laparoscopic and obstetrical/gynaecological surgeries. Results suggested a non-statistically significantly reduction in the need for rescue medication for pain (RR 0.52; 95%?CI 0.13 to 2.13) with Rosa damascena (damask rose) and ginger compared with placebo in laparoscopic and obstetrical/gynaecological surgery. None of the included studies reported on adverse events (AEs).ConclusionsThere is very low-certainty evidence regarding the efficacy of both Zingiber officinale and Rosa damascena in reducing vomiting (200 fewer cases per 1000; 288 fewer to 205 fewer), nausea (207 fewer cases per 1000; 333 fewer to 27 fewer) and the need for rescue medication for pain (666 fewer cases per 1000; 580 fewer to 752 more) in patients undergoing either laparoscopic or obstetrical/gynaecological surgeries. Among our eligible studies, there was no reported evidence on AEs.Prospero registration numberCRD42016042838.
