Active clinical trials for "Transfusion Reaction"

A prospective study designed to evaluate changes in tissue and cerebral oxygenation before and following administration of blood for patients undergoing spinal surgery. Red blood transfusions (autologous and allogeneic) are indicated to improve oxygen delivery to the tissues and hence tissue oxygenation. Despite the presumed efficacy, there are limited data to demonstrate changes in tissue oxygenation with the administration of blood. Furthermore, the administration of both autologous blood from cell saver and allogeneic blood can be associated with both acute and long-term deleterious physiologic effects which may impact the perioperative course. As such, data are needed to clearly delineate the benefits of transfusion during the perioperative period.

Kidney transplantation is the treatment of choice for ESRD. However, the life expectancy of kidney transplant patients is lower than that of the general population. Deaths recipients are due mainly to cardiovascular diseases related to a chronic inflammatory state. In addition, renal transplant patients frequently have anemia, identified as an independent cardiovascular risk factor that can be corrected by blood transfusion. But the relationship between transfusion and inflammatory condition are bidirectional. The patient's inflammatory condition will sound on the effectiveness of transfusion and transfusion could trigger an inflammatory condition. This has been reported with the said blood components "aged", especially with packed red cells in patients hospitalized in intensive care after heavy heart surgery.The main objective of this study is to evaluate the impact of early transfusions on the evolution of renal transplantation (ie death, anti-HLA immunization, acute rejection, graft loss, delayed graft function, cardiovascular events ) taking into account in the analysis: patient age at the time of transplantation, the number of incompatibility (s) (HLA class I and / or II) between the graft and the patient and sex of the recipient. This is a multicenter retrospective observational study (descriptive epidemiological study).The impact of early transfusions is determined retrospectively over a period of 6 years from 01 January 2002 to 31 December 2008, in renal transplant patients of all centers of France met the criteria for inclusion. This cohort represents about 12 000-14 000 patients

The purpose of this study was to establish the normal reference range of Thrombelastogram parameters in Hunan by a multicenter study, and to analyze the specificity of Thrombelastogram detection and the influence of gender, age and blood type on Thrombelastogram. The study will provide basic data and statistical basis for the establishment of normal reference range of Thrombelastogram in Hunan.

Transfusion reactions are defined as harms occurring during or after blood transfusion, with new heart/lung stress (eg. troubled breathing) regarded as cardiorespiratory transfusion reactions (CRTRs). CRTRs are among the most important, as the leading cause of transfusion-related harm and death. Though there are distinct classifications for these events, real life cases often don't fall neatly into a given category, with outliers regarded as "transfusion associated dyspnea (TAD)". It is unknown what TAD is -- whether it has a unique root cause, is a milder version of other known CRTRs, or is a blend of events. The purpose of this study is to better understand TAD and CRTRs by profiling them through a detailed medical history and more intensive laboratory assessment. This review of CRTRs may improve the quality/validity of final conclusions reported in the health record and to hemovigilance bodies, and uncover the nature of TAD and/or minimize CRTRs defaulting to the TAD category. Our enhanced understanding will advance diagnostic, treatment, and prevention efforts.

Allergic transfusion reactions are a common complication of transfusion by blood components containing plasma. This study aims to investigate passive transfer of Immunoglobin E antibodies as a risk factor of allergic reactions to plasma transfusion by use of Solvent Detergent plasma.

The purpose of the study is to determine whether transfusion is associated with mild pulmonary changes.

This study will determine if transfusion of platelets containing HLA antibodies (certain antibodies to white blood cells) are more likely to cause transfusion reactions than transfusion of platelets that do not contain HLA antibodies. People 18 years of age or older who donate platelets at the NIH Clinical Center may be eligible for this study. An extra tube of blood (about one teaspoon) is obtained from participating donors at the time of their donation at the NIH Platelet Center. The blood plasma in the extra tube is tested for HLA antibodies and antibodies to certain white blood cells called granulocytes. The research sample is assigned a code number for identification and sent to the HLA Laboratory in the Department of Transfusion Medicine.

ABO-incompatible red blood cell transfusions still represent an important hazard in transfusion medicine. Therefore, some countries have introduced a systematic bedside ABO agglutination test checking that the right blood is given to the right patient. However, this strategy is entirely manual, requires an extremely time-consuming learning program and relies on a subjective interpretation of agglutination on ABO test cards (for example Biorad, Diagast). The ULB spinoff Antigon developed a prototype device on the basis of a technology developed in the Translational research laboratory of CHU-Brugmann, ULB. This device is specifically dedicated to perform a "near patient" control of the blood group of the patient and of the blood bag just before transfusion, and to control that the right blood bag is given to the right patient by cross-checking their identifications. The principle of the assay relies on an agglutination and filtration in a disk including anti A,B and D antibodies. The goal of this study is to validate the analytical performances of this device (phase A) and to validate the clinical performances of this device (phase B).

Based on the principle of patient blood management, this study aims to reduce the risk of blood transfusion in allogeneic liver transplantation patients, to ensure the safety of blood transfusion, and to provide new methods and basis for restrictive blood transfusion.

Based on a review of about 10,000 patients undergoing cardiac surgery under CPB in West China Hospital of Sichuan University and the Second Affiliated Hospital of Zhejiang University, we try to evalute the effect of blood transfusion on outcomes in cardiac surgery.
