Filter by:This trial is conducted globally. The aim of this trial is to investigate safety, pharmacokinetics (the exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of concizumab administered subcutaneously to haemophilia A subjects.
A prospective, randomized clinical trial comparing blood product use and bleeding events during and after endoscopic or neurosurgical procedures in patients with cirrhosis and coagulopathy: Rotational Thromboelastometry (ROTEM) vs. conventional therapy (SCARLET).
The purpose of this study is to characterize a new test to assess the rate and time it takes to form a blood clot in people who either do or do not take aspirin.
The purpose of this study is to assess coagulation and platelet function in children with congenital heart disease, measured with a bedside device (thromboelastometry and impedance aggregometry). The investigators also aim to determine if this device detect post-cardiopulmonary bypass clotting derangements and may help to manage bleeding in this population.
Blood products are commonly used before invasive procedures in patients with end-stage liver diseases despite cirrhosis being a thrombophylic state. Traditional coagulation tests (namely INR and PLTs count) are known to be unreliable in predicting bleeding risk before invasive procedures and in representing the real coagulation status of cirrhotic patients. Notwithstanding they are still used to guide blood products administration before invasive procedures. Thromboelastography (TEG) has been shown to be effective in detecting signs of hypo-hypercoagulability possibly being an alternative method to guide blood products transfusion. The aim of this randomized controlled study was to evaluate the efficacy of TEG as a guide for blood products transfusion in cirrhotic patients undergoing invasive procedures.
This observational clinical study investigates cellular and plasmatic activation markers as well as proteins involved in coagulation and inflammation in patients being connected to different extracorporeal circulation (ECC) and circulatory support devices under intensive care conditions.
In current practice, management of coagulation during liver transplantation is performed either through standard coagulation status or with ROTEM® depending on practitioner choice and availability of materials. In this context, the ROTEM® is used since over 2 years by anesthesiologists in the digestive surgery department of the Croix Rousse hospital in Lyon, France. Indeed liver transplantation surgery is at high risk of bleeding due to coagulopathy developed by patients who are eligible, due to coagulation factor synthesis deficiencies in the cirrhotic liver. On the other hand the standard coagulation profile is a poor reflection of coagulopathy in such patients because the imbalance between pro- and anti-coagulant factors are not taken into account by PT and aPTT measures. Management of intraoperative hemorrhage may be facilitated by the ROTEM® which is performed from whole blood and which allows the detection of abnormalities in the balance between pro- and anti-coagulant factors. This technique was already evaluated in liver, cardiac, and obstetric surgery but also in traumatology. Randomized trials in liver transplantation surgery have shown changes in transfusion practices but did not focus on the consequences of such changes.
Observational study aimed at evaluating the clinical impact of a standardised diagnostic procedure for the investigation of patients with suspected mild bleeding disorder (MBD).
The purpose of this study is to evaluate efficacy and safety of a Prothrombin Complex Concentrate (PCC), BE1116. BE1116 will be used for the rapid reversal of coagulopathy induced by vitamin K antagonists in Japanese subjects who require immediate correction of international normalized ratio (INR) due to a major bleed or emergency surgery.
The purpose of this study is to find out if gross motor skills of children and young adults with bleeding disorders are different from those without bleeding disorders. The investigators will use the standardized motor test the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2 tm). The second purpose is to establish if history of joint disease secondary to bleeding affects gross motor skills. 1. Participants and setting: Subjects will include up to 100 male youth and young adults, ages 4 to 21, recruited from the patient population of the Hemophilia Treatment Center at OHSU. A mailing that describes the study may be sent to all potential subjects who receive care through the Hemophilia Treatment Center at OHSU. Data collection will occur at either clinic visits or in the home. Information, including history of change in joint structure and synovium, from existing bleeding disorder repositories at OHSU will also be used. 2. Design and Procedures: Research will be done using a prospective, cross-sectional study design to examine any relationship between a diagnosis of bleeding disorder and gross motor development. The gross motor ability of children and young adults with bleeding disorders who meet the inclusion criteria will be compared to sex-specific normative data from a standardized motor test. Information about age, type of hemophilia, presence of an inhibitor, type of management used, body composition, range of motion, and hand strength will also be collected through direct measurement and chart review. The information collected will be entered into a repository. A subject may choose to opt out of the repository while still participating in the research study. In addition, information from a current hemophilia repository will be compared to gross motor ability scores to determine if joint disease is related to skill level in this group of people. 3. Proposed analyses: Two-tailed t tests and logistic regression will be used to determine if there are any significant differences.
