Effect of Banxia Baizhu Tianma Tang for H-type hypertension: A protocol for a systematic review.

ABSTRACT: BACKGROUND:H-type hypertension is a kind of cardiovascular disease that threatens human life and health seriously. Banxia Baizhu Tianma Tang (BBTT) has been used widely for H-type hypertension while its effective evidence is not clear. Hence, we provide a systematic review protocol to evaluate the efficacy and safety of BBTT in the treatment of H-type hypertension. METHODS:Nine databases including Cochrane Library, PubMed, EMBASE, WOS, Medline, CNKI, WangFang, CBM, and VIP will be searched from their inception to October 2019. All randomized controlled trials (RCTs) of BBTT for H-type hypertension will be included. The language is limited to Chinese and English. The primary outcome measure will be the major adverse cardiac and cerebral events (MACCE). The entire process will include study selection, data extraction, assessment of bias risk, data synthesis. Data analysis will be performed using RevMan V.5.3.5 (The Cochrane Collaboration, Oxford, UK). RESULTS:This study will evaluate the efficacy and safety of BBTT in the treatment of H-type hypertension from several aspects, including MACCE, blood pressure (BP), blood lipids, inflammation indicators and homocysteine (Hcy). CONCLUSION:This systematic review will provide evidence for determining whether or not BBTT is an effective and safe intervention for H-type hypertension.

Project description:IntroductionFor situations in which effective and safe natural-derived products to treat hypertension are needed, recent studies suggest that an herbal medicine, Sihogayonggolmoryeo-tang (SYM), can improve both hypertension and concurrent mood symptoms. We aimed to evaluate the effectiveness and safety of SYM in treating hypertension.MethodsThirteen English, Korean, and Chinese databases were comprehensively searched from their inception to May 2020. Randomized controlled trials (RCTs) using SYM as a monotherapy or adjunctive therapy for hypertension were evaluated. The primary outcome was the systolic and diastolic blood pressure (BP). Descriptive analyses of the relevant data were conducted, and where appropriate data were available, a meta-analysis was performed, and the results were presented as a risk ratio or mean difference with 95% confidence intervals. The risk of bias was assessed using the Cochrane risk of bias tool, and the quality of evidence was evaluated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.ResultsSeven RCTs with 711 participants were included. Compared with placebo, SYM significantly lowered systolic and diastolic BP and concurrent depression. SYM significantly lowered systolic and diastolic BP compared with active controls; however, subgroup analysis revealed no differences between SYM and antihypertensives. In addition, SYM significantly decreased the level of concurrent depression compared with antidepressants. There was no consistent difference in BP reduction between SYM combined with antihypertensives and antihypertensives alone. No serious adverse events were reported following SYM administration. Most of the included studies had an unclear risk of bias, and the quality of evidence was generally rated "low."ConclusionCurrent evidence suggests that SYM may have the potential to lower hypertension and concurrent depressive symptoms without serious adverse events. Additional high-quality, placebo-controlled RCTs should be conducted to confirm the efficacy of SYM.

Project description:BackgroundRecent experimental and clinical studies have suggested that Hwangryunhaedok-tang (HHT), an herbal formula, could improve the lipid profiles in patients with dyslipidemia. This systematic review aimed to evaluate the effectiveness and safety of HHT monotherapy or adjunctive HHT therapy with conventional lipid-lowering drugs in managing dyslipidemia.MethodsTwelve English, Korean, Chinese, and Japanese databases were comprehensively searched from their inception to January 2020. Randomized controlled trials (RCTs) using HHT monotherapy or adjunctive HHT therapy for dyslipidemic patients were included. The primary outcome was the low-density lipoprotein cholesterol (LDL-C) level. Descriptive analyses of participant details, interventions, and outcomes were conducted and where appropriate data were available, a meta-analysis was performed and presented as a risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). The risk of bias was assessed using the Cochrane risk of bias tool and the quality of evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.ResultsNine RCTs with 536 participants were included. In comparison with lipid-lowering drugs alone, HHT as an adjunctive therapy to lipid-lowering drugs or as a monotherapy showed significantly superior (MD -1.15 mmol/L, 95% CI -1.25 to -1.05) or inferior results (MD 0.23 mmol/L, 95% CI 0.09 to 0.38), respectively, for LDL-C levels. The incidence of adverse events was significantly lower when HHT was used in addition to lipid-lowering drugs, in comparison to that with lipid-lowering drugs alone. No serious adverse events were reported in the HHT group. Most included studies showed a high risk of performance bias and the quality of evidence was rated generally "low" because of the high risk of bias and inconsistency or imprecision of the meta-analysis results.ConclusionCurrent evidence suggests that HHT may be beneficial for patients with dyslipidemia and may reduce the adverse events associated with lipid-lowering drugs. However, due to the high risk of bias of the included studies and low quality of evidence for the main findings, no definitive conclusion could be reached. Further rigorous, high-quality, and placebo-controlled RCTs should be conducted to assess the efficacy of HHT.Trial registration numberPROSPERO CRD42020164563.
