Xingnaojing for Moderate-to-severe Acute ischemic Stroke (XMAS): study protocol for a randomized controlled trial.

ABSTRACT: Xingnaojing injection (XNJ) is widely used for the treatment of stroke in China. However, there is currently a lack of high-quality evidence of its efficacy for acute ischemic stroke. The main objective of this study is to determine whether the addition of XNJ to standard care improves the 3-month functional outcome in patients with acute ischemic stroke (AIS).The XMAS study is a multicenter, prospective, randomized controlled, open-label trial with a blinded endpoints design. A total of 720 patients will be randomly allocated to either the intervention or the control group in a 1:1 ratio. The intervention group receives XNJ combined with standard care, and the control group receives standard care alone. XNJ will be administered intravenously every 12 h for 10 days. The primary outcome is the proportion of patients who are independent at 3 months after stroke onset defined as a modified Rankin Scale score of 0 to 2. Secondary outcomes include early neurological deterioration at 48 h, the change in National Institutes of Health Stroke Scale score, patient-reported outcome, symptomatic intracranial hemorrhage at 10 days, the Barthel Index score, deaths from any cause and cardiovascular events at 3 months.The results of this trial will provide critical evidence for XNJ in the treatment of AIS as a complementary approach that can be initiated after reperfusion therapy or when the AIS is not eligible for thrombolytic treatment.Clinical Trials.gov, ID: NCT02728180 .

Project description:BackgroundPneumonia is a major risk factor of death after acute stroke. In a mouse model, preventive antibacterial therapy with moxifloxacin not only prevents the development of post-stroke infections, it also reduces mortality, and improves neurological outcome significantly. In this study we investigate whether this approach is effective in stroke patients.MethodsPreventive ANtibacterial THERapy in acute Ischemic Stroke (PANTHERIS) is a randomized, double-blind, placebo-controlled trial in 80 patients with severe, non-lacunar, ischemic stroke (NIHSS>11) in the middle cerebral artery (MCA) territory. Patients received either intravenous moxifloxacin (400 mg daily) or placebo for 5 days starting within 36 hours after stroke onset. Primary endpoint was infection within 11 days. Secondary endpoints included neurological outcome, survival, development of stroke-induced immunodepression, and induction of bacterial resistance.FindingsOn intention-to treat analysis (79 patients), the infection rate at day 11 in the moxifloxacin treated group was 15.4% compared to 32.5% in the placebo treated group (p = 0.114). On per protocol analysis (n = 66), moxifloxacin significantly reduced infection rate from 41.9% to 17.1% (p = 0.032). Stroke associated infections were associated with a lower survival rate. In this study, neurological outcome and survival were not significantly influenced by treatment with moxifloxacin. Frequency of fluoroquinolone resistance in both treatment groups did not differ. On logistic regression analysis, treatment arm as well as the interaction between treatment arm and monocytic HLA-DR expression (a marker for immunodepression) at day 1 after stroke onset was independently and highly predictive for post-stroke infections.InterpretationPANTHERIS suggests that preventive administration of moxifloxacin is superior in reducing infections after severe non-lacunar ischemic stroke compared to placebo. In addition, the results emphasize the pivotal role of immunodepression in developing post-stroke infections.Trial registrationControlled-Trials.com ISRCTN74386719.

Project description:Introduction: Takotsubo syndrome (TTS) is an acute heart failure syndrome which is preceded by a variety of emotional or physical triggers, with central nervous system conditions being an important trigger. Remote ischemic conditioning (RIC) is a promising interventional treatment based on the probability that both TTS and acute coronary syndrome may respond similarly to interventions. The heart protection effect of RIC has been repeatedly confirmed in animal models and observational clinical trials; however, it has never been studied in patients with TTS after acute stroke in randomized clinical trials with a higher level of evidence. The present study will be a proof-of-concept study to determine whether RIC can reduce cardiac injury and eventually improve the heart function and clinical outcomes of TTS patients after acute stroke. Methods and Analysis: A single-center, outcome-assessor-blinded, randomized controlled trial (RCT) will be conducted to evaluate the effect of RIC in TTS patients after acute stroke. Major eligibility criteria include TTS patients diagnosed with acute stroke, which can be confirmed on computed tomography or magnetic resonance imaging; patients aged 18-75 years; patients admitted to a hospital within 48 h after the onset of acute stroke; and patients diagnosed with Takotsubo cardiomyopathy with an InterTAK diagnostic score ?50. A total of 60 eligible patients will be randomly allocated into either the RIC or the control group. The primary endpoint is a composite of death from any cause and major adverse cardiac and cerebrovascular events during the in-hospital period and at the 1- and 6-month follow-up. Ethics and dissemination: This study has been approved by the Medical Ethics Committee of Xuanwu Hospital, Capital Medical University ([2017] 072). The study findings will be presented at international conferences and published in a peer-reviewed journal. Trial registration: This study has been prospectively registered in the Chinese Clinical Trial Registry on September 10, 2018 (ChiCTR1800018290).

Project description:BackgroundAcute ischemic stroke (AIS) complicating an acute myocardial infarction (AMI) is not uncommon, but can severely worsen the clinical prognosis. This study aimed to investigate whether remote ischemic conditioning (RIC) could provide clinical benefits to patients with AIS complicating AMI.MethodsSubjects with AIS complicating AMI were recruited in this double-blind, randomized, controlled trial; assigned to the RIC and sham groups; and respectively underwent twice daily RIC and sham RIC for 2 weeks. All subjects received standard medical therapy. The primary endpoint was the rate of major adverse cardiac and cerebrovascular events (MACCEs) within 3 months after enrollment. MACCEs comprise of death from all causes, unstable anginas, AMI, acute ischemic strokes, and transient ischemic attacks.ResultsEighty subjects were randomly assigned; 37 patients in the RIC group and 40 patients in the sham-RIC group completed the 3-month follow-up and were included in the final analysis. Both RIC and sham RIC procedures were well tolerated. At 3-month follow-up, 11 subjects (29.7%) in the RIC group experienced MACCEs compared to 21 (52.5%) in the sham group (hazard ratio [HR], 0.396; 95% confidence interval, 0.187-0.838; adjusted p < 0.05). Six subjects (16.2%) in the RIC group had died at the 3-month follow up, significantly lower than the 15 (37.5%) deaths in the sham group (adjusted HR 0.333; 95% CI 0.126-0.881; p = 0.027). Seventeen subjects (45.9%) in the RIC group and 6 subjects (15.0%) in the sham group achieved functional independence (mRS score ≤ 2) at 3-month follow-up (adjusted OR 12.75; 95% CI 2.104-77.21; p = 0.006).ConclusionsAmong patients with acute ischemic stroke complicating acute myocardial infarction, treatment with remote ischemic conditioning decreased the major adverse cardiac and cerebrovascular events and improved functional outcomes at 90 days.Trial registrationURL: www.Clinicaltrialsgov .

Project description:Activation of Sirtuin (silent mating type information regulation 2 homolog) 1, or SIRT1, is an unexplored therapeutic approach for treatment of inflammatory diseases. The goal of this study was to evaluate the clinical activity and tolerability of multiple doses of SRT2104, a selective activator of SIRT1, in patients with moderate to severe psoriasis after day 84 of treatment. Forty patients were randomized 4:1 to three escalating doses of SRT2104 (250, 500, 1000 mg/d SRT2104 or placebo). Across all SRT2104 groups, 34.6% of patients (9 out of 26; 90% CI 18.0%-54.2%, p<0.0001) achieved good to excellent histological improvement based on skin biopsies taken at baseline and day 84. To evaluate the changes in expression profile with treatment and to identify pathways involved in histological improvement, a subset of 22 Pre and Post treatment biopsies from 11 patients (4 Placebo, 7 Active Treatment) were hybridized to hgu133plus2 chips. Improvement in histology was associated with modulation of IL-17 and TNF-_ signaling pathways and keratinocyte differentiation target genes. Various studies suggest a crucial role of TNF_ and IL-17 in psoriasis pathogenesis and IL-17/TNF_ synergism induces a strong induction of differentially expressed genes in psoriasis, thus advocating a crucial role of IL-17/TNF_ combination in the molecular basis of disease (Chiricozzi et al., 2010). In the current study, broad scale gene expression profiling revealed that SRT2104 significantly reduced known IL-17 and TNF_ responsive genes including SERPINB4, S100A12, SERPINB3, kynu etc. even though the sample size for this analysis was small. One of the most highly modulated genes by SRT2104 included Kynu, a gene that regulates tryptophan metabolism, known to confer antibacterial effector functions (Daubener and MacKenzie, 1999). Interestingly kynu is part of the etanercept residual genomic profile that is not modulated by etanercept therapy even though clinical efficacy is achieved. Possibly, SRT2104 may be modulating the lipid barrier of the epidermis of psoriatic skin via modulation of keratinocyte diferentiation genes, which would be consistent with the observed improvement in skin histology. These results indicate a combinatorial effect of SRT2104 on TNF_, and IL-17 inflammatory signaling pathways and keratinocyte differentiation that could be a contributing factor towards improvement in clinical scores by the SIRT1 activator, SRT2104. Paired Pre (Day 1) and Post (Day 84) Treatment samples were obtained from 4 Placebo Patients and 7 patients treated with SRT2104 at 3 different doses (250, 500, 1000 mg).
