Problems and questions from clinic and practice
Anemia is a common condition caused by a genetic condition or as a result of an immunological disease or treatment of a disorder. Transfusion of erythrocytes increases the quality of life in cases of blood loss and chronic anemia. However, blood transfusion also entails risks, such as that of immunisation, transfusion reactions and blood-borne diseases. Repeated blood transfusion causes iron overload and this may damage organs. Pregnancy can also result in immunisation against blood group antigens, and this can cause anemia in the (unborn) child and can complicate blood transfusion.
The blood supply itself is under pressure. Aging of the population results in a decrease in blood donors and an increase in the demand for blood. In addition, due to changes in the ethnic composition of the Dutch population, there is an increasing demand for a rare blood groups to prevent immunisation or, in the case of immunisation, to provide matched blood. Global movement of people and goods also increases the fast spread of blood-borne diseases.
Solutions: Sanquin products and services
Safe transfusion blood for patients with blood loss or chronic anemia is one of the most important Sanquin products. For optimum safety, Sanquin develops guidelines for transfusion treatment and diagnostics, to quickly determine clinically relevant blood groups and potential pathogenic antibodies. By supplying ‘tailor-made blood’, we want to prevent immunisation and other adverse events.
In the future we would like to know how we (i) can treat chronic anemia and limit transfusions, (ii) can improve the transfusion yield by increasing and extending the contribution of all transfused cells, (iii) can reduce immunisation against blood groups after transfusion and pregnancy, and (iv) can reduce the damage of iron overload as a result of blood transfusions.
Not only the health of the patient, but also certainly that of the donor is our responsibility. So we would like to be able to predict the period of recovery of individual donors before they are able to donate blood again.
Finally, we develop cultured blood that enables us to prevent immunisation, exclude the risk of blood-borne diseases and produce therapeutic products.
