Active clinical trials for "Hemostatic Disorders"

This study aims to investigates the role of gestational age on the prevalence of coagulation factors and components of the complement system in preterm- (≤32+0 weeks) and term neonates (≥37+0 weeks) and their role for the development of brain hemorrhage.

The researchers are trying to reduce the need for blood transfusions in subjects having surgery that will involve the use of cardiopulmonary bypass. A unit of whole blood will be removed as part of their standard of care prior to going on cardiopulmonary bypass (CPB). This unit is given back to the subject post CPB. This has been shown to reduce the need for blood transfusion in patients.

Characterizing the impact and treatment of reproductive tract bleeding on women and post-menarchal girls with bleeding disorders. Objectives: This is a cross-sectional observational study of women and girls (WG) with bleeding disorders enrolled in the American Thrombosis and Hemostasis Network (ATHN) dataset. Based on the investigators' study of currently available data of WG with bleeding disorders in the ATHNdataset, the investigators hypothesize that the information currently captured in the core data elements of the ATHNdatasest does not adequately capture data specific to WG with bleeding disorders. Further, the investigators hypothesize that it is feasible for Hemophilia Treatment Centers (HTCs) to include data points specific to WG with bleeding disorder when enrolling participants in the ATHNdataset. This hypothesis will be evaluated through the following specific aims: Specific Aim 1: Characterize reproductive tract bleeding in a cohort of WG with bleeding disorders cared for at US HTCs. Specific Aim 2: Characterize the treatment strategies for and the impact of heavy menstrual bleeding in a cohort of females with bleeding disorders cared for at HTCs. Specific Aim 3: Evaluate the feasibility of adding female specific core data points to the ATHNdataset.

A prospective single-centre non-comparative non-interventional open study has been designed to validate, in a target number of 100 trauma patients, the correlation between TICCS evaluated on the site of injury and thromboelastography made on a whole blood sample taken at the latest 30 min after patient's arrival in the resuscitation room. The aim of this study was to evaluate the capacity to discriminate trauma patients suffering from active bleeding and arly acute coagulopathy of trauma and needing Damage control resuscitation from those without this aggravating combination with a new purely clinical easy-to-measure pre-hospital score: the Trauma Induced Coagulopathy Clinical Score (TICCS).

The purpose of this study is to evaluate the clinical utility of thrombelastography (TEG) to predict and identify trauma patients at increased risk of receiving blood transfusion, develop multiple organ failure and mortality. TEG has been proposed as a superior tool to rapidly diagnose and help guide resuscitation with blood products and preclinical data suggest that TEG is both more sensitive and specific than PT or PTT for coagulation abnormalities. Based on the preclinical work led by Dr. Holcomb, our hypothesis is that the Rapid TEG will help to identify these coagulopathic patients earlier, allow for rapid MT protocol activation, and assist in developing data driven blood product transfusion guidelines.

Coagulation factor XIII (FXIII), a plasma transglutaminase, is known as the final enzyme of the coagulation cascade, responsible for a cross-linking of fibrin to strengthen blood clot. It also minimizes fibrin degradation by its cross-linking it with alfa2-antiplasmin molecules. It has been found that similar to plasma fibrinogen level, FXIII activity can be reduced in the early phase of severe trauma. Therefore, its immediate substitution is of potential therapeutic interest in trauma-induced coagulopathy. However, unlike plasma fibrinogen level evaluation, measurement of the FXIII activity is not routinely available. Therefore, targeted substitution of FXIII is practically impossible. The plasma fibrinogen level is routinely measured in severe trauma patients. Based on pathophysiologic assumptions and a limited number of published data we hypothesize that the FXIII activity correlates with fibrinogen level. In such case, indirect FXIII activity prediction by fibrinogen level measurement would be a convenient approach to enable FXIII targeted substitution. Therefore we decided to perform a prospective observational clinical trial to determine whether the low plasma fibrinogen level in severe trauma correlates with decreased FXIII activity.

Coagulopathy in cardiac surgery; a quaternary-care academic center experience Objectives: Primary: To determine incidence of coagulopathy after cardiac surgery in Thai people To determine incidence of resternotomy for stop bleeding, morbidity and mortality Secondary: To identify risk factors which associated with non-red cell transfusion and coagulopathy study decide: Retrospective chart review

This study is conducted in Europe. The aim of the study is to update the knowledge about the prevalence and severity of congenital haemophilia (A and B) in Spain.

This study is conducted in the United States of America (USA). The aim of the study is to assess the impact of pain on functional impairment and quality of life in adult persons with hemophilia (PWH) with and without inhibitors with joint bleeding.
