Xyloglucan for the treatment of acute diarrhea: results of a randomized, controlled, open-label, parallel group, multicentre, national clinical trial.

ABSTRACT: BACKGROUND:There is a strong rationale for the use of agents with film-forming protective properties, like xyloglucan, for the treatment of acute diarrhea. However, few data from clinical trials are available. METHODS:A randomized, controlled, open-label, parallel group, multicentre, clinical trial was performed to evaluate the efficacy and safety of xyloglucan, in comparison with diosmectite and Saccharomyces in adult patients with acute diarrhea due to different causes. Patients were randomized to receive a 3-day treatment. Symptoms (stools type, nausea, vomiting, abdominal pain and flatulence) were assessed by a self-administered ad-hoc questionnaire 1, 3, 6, 12, 24, 48 and 72 h following the first dose administration. Adverse events were also recorded. RESULTS:A total of 150 patients (69.3 % women and 30.7 % men, mean age 47.3?±?14.7 years) were included (n?=?50 in each group). A faster onset of action was observed in the xyloglucan group compared with the diosmectite and S. bouliardii groups. At 6 h xyloglucan produced a statistically significant higher decrease in the mean number of type 6 and 7 stools compared with diosmectite (p?=?0.031). Xyloglucan was the most efficient treatment in reducing the percentage of patients with nausea throughout the study period, particularly during the first hours (from 26 % at baseline to 4 % after 6 and 12 h). An important improvement of vomiting was observed in all three treatment groups. Xyloglucan was more effective than diosmectite and S. bouliardii in reducing abdominal pain, with a constant improvement observed throughout the study. The clinical evolution of flatulence followed similar patterns in the three groups, with continuous improvement of the symptom. All treatments were well tolerated, without reported adverse events. CONCLUSIONS:Xyloglucan is a fast, efficacious and safe option for the treatment of acute diarrhea. TRIAL REGISTRATION:EudraCT number 2014-001814-24 (date: 2014-04-28) ISRCTN number: 90311828.

Project description:Background:A recent study shows that dual antiplatelet therapy with clopidogrel plus aspirin is superior to aspirin monotherapy for minor stroke, which is defined as a National Institutes of Health Stroke Scale (NIHSS)score of ?3. However, acute mild-moderate ischaemic stroke (4?NIHSS?10) still needs aggressive antiplatelet intervention to prevent deterioration and recurrence of stroke. The efficacy and safety of dual antiplatelet therapy versus aspirin monotherapy in the population are not clear. A multicentre clinical trial is designed to evaluate the efficacy and safety of clopidogrel plus aspirin therapy versus aspirin monotherapy within 48?hours of symptom onset of mild-moderate ischaemic stroke. Methods/Design:The study is a randomised, open-label, multicentre, prospective trial with a target enrolment of 2700 patients from 60 centres in Northeast China. A treatment allocation identification number to each enrolled patient will be provided by a random number generator. The follow-up time for the clopidogrel plus aspirin and aspirin monotherapy groups is 90 days. The primary efficacy endpoint is a stroke progression event, which is defined as ?4?point increase in the NIHSS score in 48?hours. The second efficacy endpoints include new ischaemic stroke within 90 days, change in the NIHSS score within 14?days, modified Rankin Scale score on day 90 and other vascular or death events within 90 days. The safety endpoints include mucocutaneous haemorrhage, organ haemorrhage and intracranial haemorrhage, adverse events and severe adverse events. ?2 test, t-test (or Mann-Whitney test), survival analysis and Cox proportional hazards models will be conducted. The findings of the study may provide an important evidence for clinical practice for these patients. Discussion:The trial will be conducted under a rational design and will provide valuable evidence on the appropriate treatment for this population. Ethics and dissemination:The study was reviewed and approved by the Ethics Committee of the General Hospital of Shen-Yang Military Region (no K(2016) 6).

Project description:BackgroundCOVID-19 is a viral prothrombotic respiratory infection. Heparins exert antithrombotic and anti-inflammatory effects, and might have antiviral properties. We aimed to investigate whether thromboprophylaxis with enoxaparin would prevent untoward hospitalisation and death in symptomatic, but clinically stable outpatients with COVID-19.MethodsOVID was a randomised, open-label, parallel-group, investigator-initiated, phase 3 trial and was done at eight centres in Switzerland and Germany. Outpatients aged 50 years or older with acute COVID-19 were eligible if they presented with respiratory symptoms or body temperature higher than 37·5°C. Eligible participants underwent block-stratified randomisation (by age group 50-70 vs >70 years and by study centre) in a 1:1 ratio to receive either subcutaneous enoxaparin 40 mg once daily for 14 days versus standard of care (no thromboprophylaxis). The primary outcome was a composite of any untoward hospitalisation and all-cause death within 30 days of randomisation. Analysis of the efficacy outcomes was done in the intention-to-treat population. The primary safety outcome was major bleeding. The study was registered in ClinicalTrials.gov (NCT04400799) and has been completed.FindingsAt the predefined formal interim analysis for efficacy (50% of total study population), the independent Data Safety Monitoring Board recommended early termination of the trial on the basis of predefined statistical criteria having considered the very low probability of showing superiority of thromboprophylaxis with enoxaparin for the primary outcome under the initial study design assumptions. Between Aug 15, 2020, and Jan 14, 2022, from 3319 participants prescreened, 472 were included in the intention-to-treat population and randomly assigned to receive enoxaparin (n=234) or standard of care (n=238). The median age was 57 years (IQR 53-62) and 217 (46%) were women. The 30-day risk of the primary outcome was similar in participants allocated to receive enoxaparin and in controls (8 [3%] of 234 vs 8 [3%] of 238; adjusted relative risk 0·98; 95% CI 0·37-2·56; p=0·96). All hospitalisations were related to COVID-19. No deaths were reported during the study. No major bleeding events were recorded. Eight serious adverse events were recorded in the enoxaparin group versus nine in the control group.InterpretationThese findings suggest thromboprophylaxis with enoxaparin does not reduce early hospitalisations and deaths among outpatients with symptomatic COVID-19. Futility of the treatment under the initial study design assumptions could not be conclusively assessed owing to under-representation of older patients and consequent low event rates.FundingSNSF (National Research Programme COVID-19 NRP78: 198352), University Hospital Zurich, University of Zurich, Dr-Ing Georg Pollert (Berlin), Johanna Dürmüller-Bol Foundation.

Project description:Both hyperglycaemia and hypoglycaemia in acute ischaemic stroke (AIS) are associated with increased infarct size and worse functional outcomes. Thus, therapies that can maintain normoglycaemia during stroke are clinically important. Glucagon-like peptide 1 (GLP-1) analogues, including exenatide, are routinely used in the treatment of hyperglycaemia in type 2 diabetes, but data on the usefulness of this class of agents in the management of elevated glucose levels in AIS are limited. Owing to their glucose-dependent mechanism of action, GLP-1 analogues are associated with a low risk of hypoglycaemia, which may give them an advantage over intensive insulin therapy in the acute management of hyperglycaemia in this setting.The Short-Term EXenatide therapy in Acute ischaemic Stroke study is a randomised, open-label, parallel-group pilot study designed to investigate the efficacy of exenatide at lowering blood glucose levels in patients with hyperglycaemia with AIS. A total of 30 patients presenting with AIS and blood glucose levels >10 mmol/L will be randomised to receive the standard therapy (intravenous insulin) or intravenous exenatide for up to 72 h. Outcomes including blood glucose levels within the target range (5-10 mmol/L), the incidence of hypoglycaemia and the feasibility of administering intravenous exenatide in this patient population will be assessed. A follow-up visit at 3 months will facilitate evaluation of neurological outcomes post-stroke.This study has been approved by the local Institutional Review Board (Northern Sydney Local Health District Human Research Ethics Committee). The study results will be communicated via presentations at scientific conferences and through publication in peer-reviewed journals.As GLP-1 analogues require elevated glucose levels to exert their insulin potentiating activity, the use of exenatide in the management of hyperglycaemia in AIS may reduce the incidence of hypoglycaemia, thereby conferring a benefit in morbidity and mortality for patients in the long term.ACTRN12614001189617.

Project description:IntroductionThe benefits of early thromboprophylaxis in symptomatic COVID-19 outpatients remain unclear. We present the 90-day results from the randomised, open-label, parallel-group, investigator-initiated, multinational OVID phase III trial.MethodsOutpatients aged 50 years or older with acute symptomatic COVID-19 were randomised to receive enoxaparin 40 mg for 14 days once daily vs. standard of care (no thromboprophylaxis). The primary outcome was the composite of untoward hospitalisation and all-cause death within 30 days from randomisation. Secondary outcomes included arterial and venous major cardiovascular events, as well as the primary outcome within 90 days from randomisation. The study was prematurely terminated based on statistical criteria after the predefined interim analysis of 30-day data, which has been previously published. In the present analysis, we present the final, 90-day data from OVID and we additionally investigate the impact of thromboprophylaxis on the resolution of symptoms.ResultsOf the 472 patients included in the intention-to-treat population, 234 were randomised to receive enoxaparin and 238 no thromboprophylaxis. The median age was 57 (Q1-Q3: 53-62) years and 217 (46 %) were women. The 90-day primary outcome occurred in 11 (4.7 %) patients of the enoxaparin arm and in 11 (4.6 %) controls (adjusted relative risk 1.00; 95 % CI: 0.44-2.25): 3 events per group occurred after day 30. The 90-day incidence of cardiovascular events was 0.9 % in the enoxaparin arm vs. 1.7 % in controls (relative risk 0.51; 95 % CI: 0.09-2.75). Individual symptoms improved progressively within 90 days with no difference between groups. At 90 days, 42 (17.9 %) patients in the enoxaparin arm and 40 (16.8 %) controls had persistent respiratory symptoms.ConclusionsIn adult community patients with COVID-19, early thromboprophylaxis with enoxaparin did not improve the course of COVID-19 neither in terms of hospitalisation and death nor considering COVID-19-related symptoms.

Project description:OBJECTIVES:SPIRIT head-to-head (H2H) is a 52-week (Wk) trial comparing ixekizumab (IXE) with adalimumab (ADA) for simultaneous American College of Rheumatology (ACR)50 and Psoriasis Area and Severity Index (PASI)100 responses in 566 patients (distributed evenly across both groups) with psoriatic arthritis (PsA). IXE was superior to ADA for this primary end point at Wk24. We aimed to determine the final efficacy and safety results through Wk52 including a prespecified subgroup analysis of concomitant conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) use. METHODS:SPIRIT-H2H is a Wk52 multicentre, open-label, blinded-assessor study comparing IXE and ADA in bionaïve patients with PsA. Patients were randomised 1:1 to IXE or ADA with stratification by concomitant csDMARD use and presence of moderate-to-severe plaque psoriasis. Prespecified end points at Wk24 and Wk52 included musculoskeletal, psoriasis, quality-of life outcomes, subgroup analyses and safety. RESULTS:A significantly higher proportion of patients treated with IXE versus ADA simultaneously achieved ACR50 and PASI100 (39% vs 26%, p<0.001), PASI100 (64% vs 41%, p<0.001) at Wk52. Efficacy of IXE and ADA was similar at Wk52 for ACR50 (49.8% vs 49.8%, p=0.924), treat-to-target outcomes, enthesitis and dactylitis resolution. Responses to IXE were consistent irrespective of concomitant csDMARD use. Significantly more patients on IXE monotherapy versus ADA monotherapy had simultaneous ACR50 and PASI100 (38% vs 19%, p=0.007), and PASI100 responses (66% vs 35%, p<0.001) at Wk52. There were no new safety findings for IXE or ADA. CONCLUSIONS:IXE provided significantly greater simultaneous joint and skin improvement than ADA through Wk52 in bionaïve patients with PsA. IXE showed better efficacy on psoriasis and performed at least as well as ADA on musculoskeletal manifestations. IXE efficacy was consistent irrespective of concomitant csDMARD use.

Project description:IntroductionAnaemia in pregnancy remains a critical global health problem, affecting 46% of pregnant women in Africa and 49% in Asia. Oral iron therapy requires extended adherence to achieve correction of anaemia and replenishment of iron stores. Ferric carboxymaltose (FCM) is a recently established intravenous iron formulation associated with substantial advantages in safety, speed of delivery and total dose deliverable in a single infusion. We aim to determine whether FCM given once during the second trimester of pregnancy compared with standard oral iron distributed through routine antenatal services is effective and safe for treatment of moderate to severe maternal anaemia in sub-Saharan Africa.Methods and analysisThe randomized controlled trial of the effect of intravenous iron on anaemia in Malawian pregnant women (REVAMP) is a two-arm confirmatory individually randomised trial set in Blantyre and Zomba districts in Malawi. The trial will randomise 862 women in the second trimester of pregnancy with a capillary haemoglobin concentration below 100.0 g/L. The study comprises two arms: (a) intravenous FCM (20 mg/kg up to 1000 mg) given once at randomisation, and (b) standard of care oral iron (65 mg elemental iron two times per day) for 90 days (or the duration of pregnancy, whichever is shorter) provided according to local healthcare practices. Both arms receive sulfadoxine-pyrimethamine as intermittent preventive treatment in pregnancy. The primary outcome is the prevalence of anaemia (Hb <110.0 g/L) at 36 weeks' gestation. Secondary outcomes include birth weight, gestation duration and safety outcomes, including clinical malaria, serious perinatal events and postpartum haematologic and health-related outcomes in the mother and child.Ethics and disseminationEthical approval was granted by the Research Ethics Committee (COMREC P.02/18/2357) in Malawi and the Human Research Ethics Committee (WEHI: 18/02), Melbourne, Australia. The protocol is registered with the Australian and New Zealand Clinical Trials Registry. The results will be shared with the local community that enabled the research, and also to the international fora.Trial registration numberACTRN12618001268235; Pre-results.
