There are about 1645 clinical studies being (or have been) conducted in Czech Republic. 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 main objective of the European Pediatric Catheter Ablation Registry is to collect data on ablation procedures in the European pediatric population in order to improve the management of this subset of patients.
Reduction of the total IgE antibody, improved vital capacity and lung volume measured by spirometry. Improving quality of life observed in the visual analogue scale (VAS).
Multi-center, dual cohort (randomized and single vessel) study designed to demonstrate feasibility, initial safety and performance of the Kips Bay Medical, Inc. eSVS® Mesh as an external vein support device for use over saphenous vein grafts during coronary artery bypass surgery. In the Randomized Cohort, each study subject will receive a SVG without Mesh (control) and a SVG with the eSVS Mesh (treatment). In the Single Vessel Cohort, each study subject will receive one SVG with the eSVS Mesh.
The aim of this study is to determine whether a pre-treatment with high-dose statin (one day prior and just before intervention, rosuvastatin 20mg/day) has a positive impact on the occurrence of periprocedural myocardial infarction during percutaneous coronary intervention (PCI).
Citrate anticoagulation is associated with metabolic side effects which are linked to a portion of citrate reaching systemic circulation. Data on significance of systemic gain of citrate and its relationship to method configuration are missing. Patient might also receive certain dose of lactate as a buffer and a dose of glucose if acid-citrate-dextrose solution is used. The authors test variable methods of indirect estimate of systemic dose of citrate which would allow to quantify the metabolic input without mostly unavailable measurements of citrate levels.
The purpose of the study is to recognize main causes of acute decompensation of chronic congestive heart failure.
Current medical therapies are not able to prevent progression of established macroproteinuira (i.e. diabetic nephropathy) to end-stage renal failure in type 1 (insulin dependent) diabetic patients. In this setting, proteinuria is a major risk factor for mortality. Pancreas transplantation, on the contrary, can revert diabetic nephropathy and thereby prevent end-stage chronic renal failure, with theoretically lower risk of death as compared to current medical therapies.The main objective of this study is to assess superiority of isolated pancreas transplantation versus intensive exogenous insulin therapy in type 1 diabetic patients with overt diabetic nephropathy and mildly reduced renal function. The primary endpoint is a composite efficacy/failure end-point including: patient mortality and renal function impairment during 5 years in patients with badly controlled diabetes and nephropathy resisting to up-to-date nephroprotective therapies.Main secondary objectives are safety and efficacy of both regimens, including proteinuria and renal histology evaluation, metabolic control and quality of life, acute and chronic extrarenal complications of diabetes, pancreas survival and all risks related to the transplant procedure (anaesthesia, surgery and immunosuppression side-effects) and to the intensive insulin therapy management.
Vasculitis is group of diseases where inflammation of blood vessels is the common feature. Patients typically present with fever, fatigue, weakness and muscle and joint aches. These symptoms are very common among many different diseases, not just vasculitis. A clustering of other symptoms, physical examination findings, blood tests, radiology and biopsy help make the diagnosis. There are currently no criteria to help doctors make a diagnosis of vasculitis when a patient presents with these non specific symptoms and they are reliant on previous experience and disease definitions. One of the aims of this project is to develop diagnostic criteria for the primary systemic vasculitides (granulomatosis with polyangiitis (Wegener's), microscopic polyangiitis, Churg Strauss syndrome, polyarteritis nodosa, giant cell arteritis, Takayasu arteritis). We, the investigators, will do this by studying a large group of patients with vasculitis and comparing them to a large group of patients that present in a similar way, but do not have vasculitis. By comparing the 2 groups we will create a list of items to differentiate between vasculitis and 'vasculitis mimics'. We also aim to update the current classification criteria. Classification criteria are used to group patients into different types of vasculitis, once a diagnosis of vasculitis has been made, and are useful for studying patients in clinical trials with similar or identical diseases. The current classification criteria (American college of Rheumatology 1990 criteria) were developed 20 years ago, before the availability of some important diagnostic tests (e.g. antineutrophil cytoplasmic antibodies [ANCA]), and are now not consistent with some of the current disease definitions. Therefore to progress future research in vasculitis, it is important that the classification criteria are updated. We will recruit 260 patients with each of the 6 types of vasculitis and compare them with 1300 controls (patients with the 5 other types of vasculitis), in order to determine the optimal combination of symptoms, signs and investigations that classify each person into the appropriate group.
This study investigates potential protective effect of atorvastatin pre-treatment in patient with stable coronary artery disease undergoing percutaneous coronary intervention (PCI) on chronic statin therapy. Patients are randomized into two groups: atorvastatin pre-treatment group (80mg atorvastatin seven days before PCI) and control group (PCI without atorvastatin pretreatment, chronic statin treatment). Endpoint is myocardial infarction measured by troponin I and creatine kinase myocardial band.
Children and adolescents with chronic kidney disease (CKD) are at high risk for cardiovascular (CV) morbidity and mortality. Recent studies suggest that pediatric patients with even moderately impaired kidney function may be afflicted with significant early cardiac and vascular abnormalities. The pathogenesis and the natural course of CV comorbidity in pediatric CKD patients is still elusive. In this multicenter, prospective, observational study the prevalence, degree and progression of CV comorbidity in children will be characterized and related to CKD progression. The morphology and function of the heart and vessels will be monitored by sensitive, non-invasive methods and will be compared with aged matched healthy controls. Multiple potential clinical, anthropometric, biochemical, and pharmacological risk factors will be monitored prospectively and will be related to CV status. Genotyping might identify predisposing genetic factors for progression of CV comorbidity and underlying nephropathies.
