There are about 2333 clinical studies being (or have been) conducted in Ireland. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The great diversity of regimens and treatment lines, the different efficacy of these, mostly due to the increase in bacterial antibiotic resistance and regional differences, requires a continuous critical analysis of clinical practice, evaluating systematically the efficacy and safety of the different regimens and the cost-effectiveness of the different diagnostic-therapeutic strategies. This will help in the design of an efficient and optimized treatment that will reduce number of re-treatments, diagnostic tests and the appearance of associated pathologies such as peptic ulcers, gastrointestinal bleeding and, probably, gastric cancers. Therefore, the evaluation of real clinical practice using non-interventionist registries will help to improve the design and organization of European Consensus on the management of H. pylori infection, which is the best way to establish healthcare efficiency. Primary aim To obtain a database registering systematically over a year a large and representative sample of routine clinical practice of European gastroenterologists in order to produce descriptive studies of the management of H. pylori infection. Secondary aims 1. To evaluate H. pylori infection consensus and clinical guidelines implementation in different countries. 2. To perform studies focused on epidemiology, efficacy and safety of the commonly used treatments to eradicate H. pylori. 3. To evaluate accessibility to healthcare technologies and drugs used in the management of H. pylori infection. 4. To allow the development of partial and specific analysis by the participating researchers after approval by the Registry's Scientific Committee Methodology Non-interventionist prospective multicentre international registry promoted by the European Helicobacter Study Group. A renowned gastroenterologist from each country was selected as Local Coordinator (30 countries). They will in turn select up to ten gastroenterologists per country that will register the routine clinical practice consultations they receive over 10 years in an electronic Case Report Form (e-CRF). Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation and outcome data. The database will allow researchers to perform specific subanalysis after approval by the Scientific Committee of the study.
This trial is designed to assess if there is evidence of subclinical joint bleeding on MRI/X-Ray in adults with severe Haemophilia A while on standard and/or pharmacokinetically tailored prophylaxis regimens. Participants with severe Haemophilia A will have longitudinal MRI and XRay imaging of their elbows, ankles and knees at 0, 6 and 18 months while on standard ( 0-6 months) and then pharmacokinetically tailored (7-18 months) recombinant Factor VIII prophylaxis.
Pain is the dominant symptom of knee osteoarthritis and recent evidence suggests factors outside of local joint pathology, such as pain sensitization, can contribute significantly to the pain experience. It is unknown how pain sensitization influences outcomes from commonly employed interventions such as physiotherapy. The aims of this study are, firstly to identify people with knee OA who display signs and symptoms associated with pain sensitization using clinical tools and quantitative sensory testing. Secondly, we will investigate if indications of pain sensitization at baseline are associated with poor outcome following physiotherapy. Methods and analysis: This is a multi-centre prospective cohort study with 140 participants. Eligible patients with moderate/severe symptomatic knee osteoarthritis will be identified at hospital outpatient clinics. A baseline assessment will provide a comprehensive description of the somatosensory characteristics of each participant by means of clinical examination, quantitative sensory testing and validated questionnaires measuring pain and functional capacity. Participants will then undergo physiotherapy treatment, in line with current clinical guidelines. Follow-up post physiotherapy treatment (estimated to be at 3 months) will assess pain, disability (sub-scales of Western Ontario and McMasters University Score Osteoarthritis Index) and participants' global rating of change. These primary outcome measures will dichotomise participants into treatment 'responders' and 'non-responders' according to the Osteoarthritis Research Society International (OARSI) treatment responder criteria. For data analysis results from pressure pain thresholds, temporal summation and conditioned pain modulation will create a composite score of pain sensitization. Logistic regression will explore the relationship between response to physiotherapy and pain sensitization at baseline while accounting for various cofounders.
The investigators hypothesize that aligning digital data on PEF and adherence with the patient's own clinical course achieves better asthma control and identifies risks for future loss of control, compared to current best practice. The study has an adherence optimisation phase, week 1-12 followed by a medication management phase, week 12 to week 32. The investigators will compare two asthma education interventions, standard Guideline recommended practice and feedback from the individual's own INCA device, which assesses inhaler adherence and relates adherence with changes in PEF and symptom scores over time. The study has two co-primary endpoints, one will be a comparison of the adherence to therapy and the other will be a comparison of the appropriateness of medication prescriptions between the two study groups.
The overall aim of this project is to improve the outcome of patients diagnosed with ependymoma by improving and harmonising the staging and the standard of care of this patient population and to improve the investigators understanding of the underlying biology thereby informing future treatment. The program will evaluate new strategies for diagnosis (centralized reviews of pathology and imaging) and new therapeutic strategies in order to develop treatment recommendations. Patients will be stratified into different treatment subgroups according to their age, the tumour location and the outcome of the initial surgery. Each subgroup will be studied in a specific randomised study to evaluate the proposed therapeutic strategies. Stratum 1: The aim of the stratum 1 is to evaluate the clinical impact of 16-week chemotherapy regimen with VEC-CDDP following surgical resection and conformal radiotherapy in terms of progression free survival in patients who are > 12 months and < 22 years at diagnosis, with completely removed intra cranial Ependymoma. Stratum 2: This stratum is designed as a phase II trial for patients who are > 12 months and < 22 years at diagnosis, with residual disease to investigate the possible activity of HD-MTX by giving to all patients the benefit of VEC chemotherapy whilst randomising half of patients to receive additional HD-MTX. Patients will receive conformal radiotherapy (cRT). For patients who remain with a residual inoperable disease after induction chemotherapy and cRT, an 8 Gy boost of radiotherapy to the residual tumour will be delivered immediately after the end of the cRT. Stratum 3 This stratum is designed as a phase II trial to evaluate the benefit of postoperative dose intense chemotherapy administered alone or in combination with valproate in children <12 months of age or those not eligible to receive radiotherapy .
This study will examine outcomes for patients treated by planned culotte stenting and compare outcomes with 2 different stent platforms, the next generation Synergy II and the Xience Xpedition DES platforms.
Major vascular surgery involves operations to repair swollen blood vessels, clear debris from blocked arteries or bypass blocked blood vessels. Patients with these problems are a high-risk surgical group as they have generalized blood vessel disease. These puts them at risk of major complications around the time of surgery such as heart attacks , strokes and death. The mortality following repair of a swollen main artery in the abdomen is about 1 in 20. This contrasts poorly with the 1 per 100 risk of death following a heart bypass. Simple and cost-effective methods are needed to reduce the risks of major vascular surgery. Remote ischaemic preconditioning (RIPC) may be such a technique. To induce RIPC, the blood supply to muscle in the patient's arm is interrupted for about 5 minutes. It is then restored for a further five minutes. This cycle is repeated three more times. The blood supply is interrupted simply by inflating a blood pressure cuff to maximum pressure. This repeated brief interruption of the muscular blood supply sends signals to critical organs such as the brain and heart, which are rendered temporarily resistant to damage from reduced blood supply. Several small randomized clinical trials in patients undergoing different types of major vascular surgery have demonstrated a potential benefit. This large, multi-centre trial aims to determine whether RIPC can reduce complications in routine practice.
This is a multi-centre, multi-national, prospective, observational study of Friedreich's Ataxia (FRDA) with a control group to: - obtain natural history data on individuals affected by FRDA - relate clinical assessments and results from proteomic analyses - expedite identification and recruitment of participants for clinical trials - develop and validate sensitive and reliable outcome measures for detecting onset and change over the natural course of FRDA which may also be potential outcome measures for use in future clinical trials and clinical care - plan for future research studies
This study aims to demonstrate if remote ischaemic preconditioning (RIPC) may confer renal protection in patients undergoing peripheral angioplasty. Patients will be randomised to receive RIPC and biomarkers for renal injury will be analysed post procedure to determine if any protective benefit was obtained.
This study aims to assess if applying an ischaemic insult to an arm before giving intravenous contrast will help decrease the incidence of developing contrast induced acute renal injury in patients undergoing contrast-enhanced CT Scans. The main research question is 'In adult in-patients undergoing contrast-enhanced CT scans, does remote ischaemic pre-conditioning (RIPC) induced by brief arm ischaemia and reperfusion, when compared to control, reduce the proportion of patients developing contrast-induced acute kidney injury in the first 3 post-scan days?
