Pre- vs. Postoperative Thromboprophylaxis in Pancreatic Surgery
Thromboprophylaxis for pancreatic surgery can be commenced either preoperatively or postoperatively. Despite a clear trade-off between thrombosis and bleeding in pancreatic surgery patients, there is no international consensus when thrombosis prophylaxis should be commenced in patients undergoing pancreatic surgery. There are no prospective randomized trials in this field, and current …
Validation of Point-of-care Thromboelastography (TEG 6s) in Pediatric Patients
The goal of this observational study is to learn about the performance of the TEG6s in normal pediatric patients. The main questions it aims to answer are: What are the normal TEG 6S lab results in normal pediatric patients and how do they compare to existing published reference ranges. Participants …
Coagulation Disorders Secondary to Two Plasmapheresis Techniques (Double Filtration Plasmapheresis vs. PFS). Descriptive Pilot Study.
Therapeutic plasmapheresis causes changes in haemostasis by purifying many of the circulating factors involved. Few reliable data are available on these changes and most studies are limited to coagulation factor assays before and after the session, with little data documenting the kinetics of regeneration of these factors. It is recognized …
Early Genomic Testing for Inherited Bleeding Disorders
The investigators aim to test the introduction of genomic testing early in the diagnostic pathway for inherited bleeding disorders in patients who have not received a diagnosis after first-line testing. The goal of this clinical trial is to test the introduction of genomic testing early in the diagnostic pathway for …
Recombinant VWF Concentrate and ECMO
Adult patients on extracoporeal membrane oxygenation (ECMO) frequently experience bleeding, which is in part caused by acquired von Willebrand syndrome (vWS). Prior in vitro studies have shown that the addition of recombinant von Willebrand Factor (vWF) to ECMO patient blood samples, normalizes platelet adhesion and thrombus formation. This study is …
Study Protocol: Impact of Metamizole (Optalgin®) on Anti-Xa Concentrations in Oncology Patients Receiving DOACs
Evaluation of the Effect of metamizole (Optalgin®) on Anti-Xa Levels in Oncology Patients Receiving Direct Oral Anticoagulants (DOACs)
Heavy Menstrual Bleeding Progestin Treatment in Bleeding Disorders Study
The goal of this multicenter prospective observational study and registry of U.S. adolescents and young adults with heritable bleeding disorders is to determine the bleeding outcomes, satisfaction, hemostatic parameter changes, and patient reported quality of life after 6 months of use of either of two commonly used hormonal treatments for …
Comparative Study of Tranexamic Acid Dosing in Cardiac Surgery
Tranexamic axid is routinely used as an antifibrinolytic agent in cardiac surgery to reduce the risk of blood loss and transfusion. However, there is no consensus regarding the dosage regimen of tranexamic acid that should be administered. The purpose of this study is to compare different dosages of tranexamic acid …
Embolization in Hereditary Coagulopathies
This is a longitudinal, prospective study, which will include 30 subjects with hereditary coagulopathies, with arthropathy, chronic synovitis resulting from hemarthrosis of the elbows, knees and/or ankles followed up at the Centro de Hemofilia HCFMUSP, after approval by the ethics and research committee. They will undergo imaging tests (X-rays and …
International Registry of Dengue Infection in Congenital Bleeding Disorders (DengueCBDR)
Dengue fever, a viral infection transmitted by Aedes mosquitoes, is a major health issue in tropical and subtropical regions. Around 20-30% of symptomatic patients developed Dengue Hemorrhagic Fever (DHF), which leads to impaired hemostasis, subsequently increasing the risk of bleeding. The hemostatic abnormalities associated with dengue infection included vascular permeability, …
