Efficacy and safety of the compound Chinese medicine SaiLuoTong in vascular dementia: A randomized clinical trial.

ABSTRACT:

Introduction

No licensed medications are available to treat vascular dementia (VaD).

Methods

Patients were randomly assigned to experimental groups (SaiLuoTong [SLT] 360 or 240 mg for groups A and B for 52 weeks, respectively) or placebo group (SLT 360 mg and 240 mg for group C only from weeks 27 to 52, respectively).

Results

Three hundred twenty-five patients were included in final analysis. At week 26, the difference in VaD Assessment Scale-cognitive subscale scores was 2.67 (95% confidence interval, 1.54 to 3.81) for groups A versus C, and 2.48 (1.34 to 3.62) for groups B versus C (both P < .0001). However, at week 52, no difference was observed among the groups on the VaD Assessment Scale-cognitive subscale (P = .062) because of the emerging efficacy of SLT in placebo beginning at week 27.

Discussion

This study suggests that SLT is effective for treatment of VaD, and this compound Chinese medicine may represent a better choice to treat VaD.

Project description:Vascular dementia (VaD) accounts for 15-20% of all dementia cases. It is a syndrome of acquired cognitive impairment with a complex pathophysiological basis. A novel herbal formulation (Sailuotong; SLT) consisting of Panax ginseng C.A Mey, Ginkgo biloba L and Crocus sativus L extracts was developed to treat VaD. Preclinical animal studies found significant improvements in memory and in pathogenic biochemical parameters. Appropriate safety of SLT was shown in acute and chronic toxicity studies, and early clinical trials of SLT demonstrated enhancements in cognition in VaD patients. A fully powered study with a long intervention period is needed to confirm the efficacy and safety of this novel intervention. A rigorous phase III clinical trial was developed with the aim of recruiting 238 patients diagnosed with mild to moderate probable VaD, or VaD mixed with Alzheimer's disease (where cerebrovascular disease is the clinical dominant contributor to dementia, abbreviated as CVD+AD). Using a permuted block strategy, participants will be randomly allocated to receive SLT (120 mg bd) or placebo capsules for an intervention period of 52 weeks and will be followed-up for an additional 13 weeks. The primary outcome measures are the Vascular Dementia Assessment Scale-cognitive subscale and Alzheimer's Disease Cooperative Study-Activities of Daily Living scale. Secondary outcome measures include the Clinician's Interview Based Impression of Change-Plus, CLOX, EXIT-25, Neuropsychiatric Inventory-Clinician rating scale, and Dementia Quality of Life questionnaire. Safety is assessed through adverse event reports and liver, renal, and coagulation studies. Primary and secondary outcome measures will be compared between treatment and placebo groups, using intention to treat and per protocol analyses. We hypothesise that a 52-week treatment of SLT will be clinically effective and well tolerated in participants with VaD or AD+CVD. This project will provide vital efficacy and safety data for this novel treatment approach to VaD.

Project description:BackgroundTreatments for coronavirus disease 2019 (COVID-19) are limited by suboptimal efficacy.MethodsFrom January 30, 2020 to March 23, 2020, we conducted a non-randomised controlled trial, in which all adult patients with laboratory-confirmed COVID-19 were assigned to three groups non-randomly and given supportive treatments: Group A, Lopinavir-Ritonavir; Group B, Huashi Baidu Formula (a Chinese medicineformula made by the China Academy of Chinese Medical Sciences to treat COVID-19, which is now in the clinical trial period) and Lopinavir-Ritonavir; and Group C, Huashi Baidu Formula. The use of antibiotics, antiviruses, and corticosteroids was permitted in Group A and B. Traditional Chinese medicine injections were permitted in Group C. The primary outcomes were clinical remission time (interval from admission to the first time the patient tested negatively for novel coronavirus or an obvious improvement was observed from chest CT) and clinical remission rate (number of patients whose clinical time was within 16 days/total number of patients).ResultsA total of 60 adult patients with COVID-19 were enrolled at sites in Wuhan, China, and the sample size of each group was 20. In Groups A, B and C, the clinical remission rates were 95.0%%(19/20), 100.0%%(20/20) and 100.0%%(20/20), respectively. Compared with Groups A and B, the clinical remission time of Group C was significantly shorter (5.9 days vs. 10.8 days, p < 0.05; 5.9 days vs. 9.7 days, p < 0.05). There was no significant difference among Groups A, B, and C in terms of the time taken to be released from quarantine. The clinical biochemical indicators and safety indexes showed no significant differences among the three groups.ConclusionsOur findings suggest that Lopinavir-Ritonavir has some efficacy in the treatment of COVID-19, and the Huashi Baidu Formula might enhance this effect to an extent. In addition, superiority was displayed in the treatment of COVID-19 through a combination of the Huashi Baidu Formula and traditional Chinese medicine injection. In future, well-designed prospective double-blinded randomised control trials are required to confirm our findings.

Project description:BackgroundHeart failure with preserved ejection fraction (HFpEF) is a large subtype of heart failure (HF) characterized by exercise intolerance and reduced quality of life. Studies have shown that traditional Chinese medicine (TCM) combined with conventional Western medicine has a good effect on improving exercise tolerance and quality of life in patients with HFpEF, but the overall quality of evidence is low. This study aimed to determine the safety and efficacy of Yangyin Shuxin (YYSX) decoction in the treatment of HFpEF.MethodsA prospective, single-blind, single-center, randomized controlled clinical study was conducted. 64 patients with HFpEF were randomly assigned to receive oral YYSX decoction (150 ml, twice a day) combined with conventional Western treatment or conventional Western treatment alone at a ratio of 1 : 1. The course of treatment was 2 weeks, and the follow-up was 3 months. The primary outcome was peak oxygen uptake (peak VO2) measured by the cardiopulmonary exercise test (CPET). Furthermore, the safety of YYSX decoction was assessed.Results63 patients (31 in the YYSX group and 32 in the control group) were included in the full analysis set. The peak VO2 of the YYSX group was significantly higher than that of the control group (12.04 ± 3.41 vs. 11.02 ± 3.33, P = 0.013) after 2 weeks. The maximum voluntary ventilation (MVV) was significantly higher in the YYSX group compared with the control group (P < 0.05). The YYSX group had a higher EQ-visual analogue scale (EQ-VAS) score (71.13 ± 13.95 vs. 70.94 ± 13.70, P < 0.05) and a lower TCM Four-Dimensional Diagnostic Information Scale (TCMFDIS) score (49.74 ± 24.73 vs. 64.16 ± 27.15, P < 0.05) than the control group. There was no statistical difference between two groups (P = 0.160), although 51.61% of patients in the YYSX group showed a decrease in brain natriuretic peptide (BNP) levels of at least 30%, compared with 37.50% of patients in the control group. No serious adverse events were reported in either group, but systolic and diastolic blood pressure decreased and serum sodium levels increased slightly in the control group.ConclusionThe YYSX decoction combined with conventional Western treatment was superior to the conventional Western treatment alone in improving exercise tolerance, quality of life, and cardiopulmonary function of patients with HFpEF. YYSX decoction is safe and may prevent a drop in blood pressure and sodium retention. Trial Registration. Chinese Clinical Trial Registry (www.chictr.org/cn/, No. ChiCTR-IOR-17014206).
