Filter by:Stable chronic hemodialysis patients are included in this observational study. After a midweek dialysis (test moment 1), the hemodialyzer is dried and scanned in a micro Computed Tomography scanner to quantify the number of patent fibers. All dialysis parameters are collected as well as the anticoagulation dose. During the same session, patients are asked about their bleeding and quality of life status. Four (test moment 2) respectively eight weeks later (test moment 3), patients are asked again for their bleeding and quality of life status using validated questionnaires.
Freeline is developing adeno-associated virus (AAV) vector based gene therapies for a number of diseases and is actively advancing a programme in Haemophilia B (HB). This study aims to collect prospective data to characterise bleeding events and Factor IX (FIX) concentrate consumption in HB patients that can be used as baseline for participants who elect to participate in a subsequent Freeline gene therapy study. The study will also screen participants for antibodies to a novel AAV vector to assess their suitability for inclusion in a Freeline gene therapy treatment study.
The aim of this prospective, observational study is to establish a dataset on the frequency of bleeding events, as well as other characteristics of bleeding events and FVIII infusions, in patients with clinically severe hemophilia A receiving prophylactic FVIII replacement therapy as standard of care. The data collected from this study may assist in providing baseline information for comparison to the Spark's investigational hemophilia A gene therapy in future Phase 3 studies.
SPK-8016 is in development for the treatment of patients with inhibitors to FVIII. This Phase 1/2, open-label, non-randomized, dose-finding study to evaluate the safety, efficacy, and tolerability of SPK-8016 in adult males with severe hemophilia A and no measurable inhibitor against FVIII.
The alterations of coagulation and fibrinolysis parameters have been described in patients with endogenous Cushing's syndrome (CS) and those treated with glucocorticosteroids (GCs). The change in hemostatic process is associated with an increased risk of venous thromboembolic events (VTE) and pulmonary embolism (PE). Anticoagulation prophylaxis reduces thromboembolic complications in endogenous and exogenous hypercortisolism. The impact of the intravenous GCs therapy on hypercoagulability, however, remains unclear and perplexing. According to the European Group On Graves' Orbitopathy (EUGOGO), patients with active, severely symptomatic and sight-threatening Graves' orbitopathy (GO) should be treated with high dose intravenous methylprednisolone (IVMP) pulses. There are, however, reports of fatal side effects that may be associated with this therapy (e.g.: PE, myocardial infarction, severe cerebrovascular events, acute liver damage and sudden death). For this reason, the cumulative dose of IVMP should not exceed 8 g within each treatment course, and pulses should not be given on consecutive or alternate days, except for the case of dysthyroid optic neuropathy. Nevertheless, even smaller cumulative therapy may be associated with fatal cardiovascular complications. Hence the aim of our study was to evaluate the effects of IVMP therapy on hemostatic process in patients with GO. All of patients were treated according to EUGOGO recommendations with standard doses of methylprednisolone with standard recommended schedule. Inclusion criterion for the therapy was according to EUGOGO guidelines moderate-to-severe and active GO (12 pulses of IVMP 6x0.5g followed by 6x0.25g every week).
In this observational study a comparison is made between two different monitors for measurement of the activated clotting time (ACT): mechanical versus biochemical techniques
This study is designed to analyze the effect exosomes derived from red blood cell units have on blood coagulation and platelet function. It is an in vitro study using healthy volunteers' blood.
Type of study:Prospective, single-center, non-therapeutic, of routine care No randomization, no modifications of the usual care, study results are not available for the physicians in charge of the patient. Objectives: - The main objective of this study is to evaluate the ability of the thromboelastogram (ROTEM®) to detect clotting disorders related to pancreas-kidney transplantation, comparing ROTEM ® profiles during the perioperative period of two different types of transplantation (kidney alone and simultaneous pancreas-kidney) - The secondary objectives are: 1. To assess the incidence and type of coagulation disorders during the perioperative period of these two types of transplantation 2. To study correlation values between thrombolelastogram and standard coagulation parameters Population study: - Evaluated group: 40 pancreas-kidney recipients - Control group: 80 kidney recipients - Recruitment periods: 24 months - Patient Monitoring: 48 hours - Total duration of the study: 36 months. - Ethics: Study of routine care. Oral and written information given to patients. Validation of the study protocol by the local ethics committee (CPP Sud Est II: Protocol No. HCL / P 2012.727)
In this study, the investigators would like to compare a heparin-coated tubing system for minimized extracorporeal circulation (MECC) with the conventional tubing system for MECC, which does not contain heparin coating. The MECC system has been used since 14 years in the investigators' hospital as an extracorporeal system to support circulation and provide oxygen to the tissues during coronary artery bypass grafting. Until today, the investigators performed more than 5000 MECC procedures in their department.
About 25% medicines prescribed for long term conditions are not taken as directed, and approximately 15% people receiving a new medicine take few, if any, doses. The New Medicine Service (NMS) is a community pharmacy service that started in England in October 2011 which involves the pharmacist providing additional support to patients starting a new medicine for some breathing problems (asthma & COPD), high blood pressure, adult onset diabetes or medicines which reduce blood clotting. It aims to improve the way patients take their medicines improving outcomes and reducing costs to the National Health Service (NHS). The investigators will assess the effectiveness and cost effectiveness of the NMS using a research study where some people will receive the NMS, and some won't, so The investigators can look at the effect of the NMS on problems with their medicines, medicines taking and use of the NHS in general. Data will be collected in the East Midlands, South Yorkshire and London areas. The investigators will recruit 500 patients from a range of different pharmacies and follow them up at six, ten and twenty six weeks after starting their new medicine to assess effects on medicines taking behaviour, patients' reported problems with medicines, referrals to their General Practitioner (GP) and use of NHS resources. The investigators will compare the data gathered from this study with that being collected routinely by all pharmacies in England to provide wider estimates of cost effectiveness. The investigators will also explore how the NMS service is being implemented by pharmacies. A sample of patients from the main study will be followed in more detail. This will involve recording the consultations with the pharmacist and also interviewing patients about their experience of the service. The investigators will interview the patients GP to investigate their views of the service. The investigators will also try to understand why people decline the invitation for the NMS
