Rituximab for prevention of delayed hemolytic transfusion reaction in sickle cell disease.
نویسندگان
چکیده
Delayed hemolytic transfusion reaction (DHTR), a life-threatening transfusion complication in sickle cell disease (SCD), is characterized by a marked hemoglobin drop with destruction of both transfused and autologous red blood cells (RBCs) and exacerbation of SCD symptoms. One mechanism of RBCs destruction is auto-antibody production secondary to transfusion. As rituximab specifically targets circulating B cells, we thought that it could be beneficial in preventing this immune-mediated transfusion complication. We report the case of a SCD patient who previously experienced DHTR with auto-antibodies and who needed a new transfusion. DHTR recurrence was successfully prevented by rituximab administration prior transfusion, supporting the safe use of rituximab to prevent DHTR in SCD patients as a second line approach when other measures failed.

We report on a case of delayed hemolytic transfusion reaction (DHTR) occurred 7 days after an erythrocytapheresis or eritroexchange procedure (EEX) treated with rituximab and glucocorticoids in a 15-years old patient with sickle cell disease. EEX was performed despite a previous diagnosis of alloimmunization, in order to reduce hemoglobin S rate before a major surgery for avascular necrosis of ...

Patients with sickle cell disease frequently require red blood cell transfusions . However, transfusions can cause delayed hemolytic transfusion reaction (DHTR), a serious and potentially life-threatening complication of alloimmunization that results in hemolysis of transfused as well as patients’ own red cells . Although we are beginning to understand some of the pathophysiology and risk facto...

متن کاملDelayed hemolytic transfusion reaction in children with sickle cell disease.
BACKGROUND Transfusion is a cornerstone of the management of sickle cell disease but carries a high risk of hemolytic transfusion reaction, probably because of differences in erythrocyte antigens between blood donors of European descent and patients of African descent. Patients may experience hemolytic transfusion reactions that are delayed by from a few days to two weeks and manifest as acute ...
متن کاملRed blood cell alloimmunization in sickle cell disease: pathophysiology, risk factors, and transfusion management.
Red blood cell transfusions have reduced morbidity and mortality for patients with sickle cell disease. Transfusions can lead to erythrocyte alloimmunization, however, with serious complications for the patient including life-threatening delayed hemolytic transfusion reactions and difficulty in finding compatible units, which can cause transfusion delays. In this review, we discuss the risk fac...
