Antibody Incompatible Transplantation Sample Clauses

Antibody Incompatible Transplantation. Conventionally, blood group compatible and crossmatch negative transplants are carried out between donor and recipient to avoid hyperacute rejection. This type of rejection is characterized clinically by catastrophic graft vascular thrombosis, haemorrhage and necrosis as the complement and coagulation cascades are activated by antibody binding to target antigens on the graft endothelial cells (54). Typically, HLA allosensitisation occurs after patients have been exposed to previous solid organ transplants, blood transfusions, pregnancies, cardiac devices, coronary bypass grafting and tissue grafting. The first reported study that showed a correlation between transplant graft loss and a positive pretransplant crossmatch test was reported by Xxxxx and Xxxxxxxx in 1969 (55).This work effectively eliminated the incidence of hyperacute rejection, prior to which the incidence of this devasting condition in second renal transplants was almost as high as 50% (56). Hence for kidney transplantation, cytotoxic cross match testing aims to detect circulating antibodies in recipient serum against HLA on donor lymphocytes making hyperacute rejection in the clinical setting an (almost) never event. However, antibody incompatibility between donor and recipient persists and is a major problem in renal transplantation. Approximately 30% of patients on the kidney transplant waiting list will be highly sensitised (anti HLA) making it very difficult to match them to a potential living donor. In the United Kingdom, the level of sensitization is defined by the calculated reaction frequency (cRF) and represents the percentage of the last 10,000 deceased donors that have HLA that would react with a recipient’s serum. A recipient would be considered highly sensitised if their cRF was greater than or equal to 85%. This means that they would have antibodies that would react with HLA of at least 85% of the last 10,000 donors. Incompatibility with their living donor coupled with a high level of sensitisation also significantly increases their time on the deceased donor waiting list – almost two-fold (57)(58). In a recent review, the incidence of DSA in previously non-sensitised renal recipients has been reported as 7 % by 5 years post transplantation, 20 % by 10 years and up to 40 % in children (30). Furthermore these preformed antibodies in sensitized patients expose them to higher risk of antibody mediated rejection once transplanted (59), thus making the presence of antibody a major ...

  • Human Leukocyte Antigen Testing This plan covers human leukocyte antigen testing for A, B, and DR antigens once per member per lifetime to establish a member’s bone marrow transplantation donor suitability in accordance with R.I. General Law §27-20-36. The testing must be performed in a facility that is: • accredited by the American Association of Blood Banks or its successors; and • licensed under the Clinical Laboratory Improvement Act as it may be amended from time to time. At the time of testing, the person being tested must complete and sign an informed consent form that also authorizes the results of the test to be used for participation in the National Marrow Donor program.

  • Influenza Vaccine Upon recommendation of the Medical Officer of Health, all employees shall be required, on an annual basis to be vaccinated and or to take antiviral medication for influenza. If the costs of such medication are not covered by some other sources, the Employer will pay the cost for such medication. If the employee fails to take the required medication, she may be placed on an unpaid leave of absence during any influenza outbreak in the home until such time as the employee has been cleared by the public health or the Employer to return to the work environment. The only exception to this would be employees for whom taking the medication will result in the employee being physically ill to the extent that she cannot attend work. Upon written direction from the employee’s physician of such medical condition in consultation with the Employer’s physician, (if requested), the employee will be permitted to access their sick bank, if any, during any outbreak period. If there is a dispute between the physicians, the employee will be placed on unpaid leave. If the employee gets sick as a reaction to the drug and applies for WSIB the Employer will not oppose the application. If an employee is pregnant and her physician believes the pregnancy could be in jeopardy as a result of the influenza inoculation and/or the antiviral medication she shall be eligible for sick leave in circumstances where she is not allowed to attend at work as a result of an outbreak. This clause shall be interpreted in a manner consistent with the Ontario Human Rights Code.
