Hyperhaemolytic Syndrome in Sickle cell disease: clearing the cobwebs

Alexandros G.Sfakianakis shared this article with you from Inoreader Hyperhaemolytic Syndrome in Sickle cell disease: clearing the cobwebs Μέσω MPP : Last 20 articles Sickle cell anaemia presents with a dynamic background haemolysis and deepening anaemia. This increases the demand for transfusion if any additional strain on haemopoiesis is encountered due to any other physiological or pathological. Patients with cerebrovascular accident are placed on chronic blood transfusion; those with acute sequestration and acute chest syndrome are likewise managed with blood transfusion. These patients are prone to develop blood transfusion complications including alloimmunization and hyperhaemolytic syndrome (HHS). This term is used to describe haemolysis of both transfused and 'own' red cells occurring during or post-transfusion in sickle cell patients. Hyperhaemolysis results in worsening post-transfusion haemoglobin due attendant haemolysis of both transfused and autologous red cells. The mechanism underlying this rare and usually fatal complication of sickle cell has been thought to be secondary to changes in the red cell membrane with associat ed immunological reactions against exposed cell membrane phospholipids. The predisposition to HHS in sickle cell is also varied and the search for a prediction pattern or value has been evasive. This review to discusses the pathogenesis, risk factors and treatment of hyperhaemolytic syndrome, elaborating what is known of this rare condition. View on the web Inoreader.
