Paroxysmal nocturnal haemoglobinuria is an acquired haemolytic anaemia that may develop into aplastic anaemia or myeloid leukaemia. It has recently been shown that paroxysmal nocturnal haemoglobinuria is due to a defective coupling of specific proteins to glycolipids on the cell surface of haematopoietic cells. One of these proteins is decay-accelerating factor (DAF), and the absence of DAF on the surfaces of blood cells leads to the haemolytic symptoms. The molecular biology of DAF and its relationship to paroxysmal nocturnal haemoglobinuria symptoms is described in this brief review. The molecular defect of paroxysmal nocturnal haemoglobinuria is illustrated in a case report.

After 1940, the number of splenectomies performed in the United States and elsewhere increased rapidly. Splenectomy for Banti's disease and malaria decreased gradually into disrepute. Removal of the spleen for idiopathic thrombocytopenic purpura, congenital spherocytic anemia and acquired hemolytic anemia became accepted practice. However, debate still continues regarding the proper indications for splenectomy in Gaucher's disease, Felty's syndrome and leukemia.

THE HEMOLYTIC ANEMIAS OF UNKNOWN CAUSE CAN BE SEPARATED INTO TWO MAIN GROUPS: (1) those produced by a defect in cell structure, which is usually hereditary, and (2) those due to a hemolysin of immune-body type.The hemolytic anemias associated with hypersensitivity to drugs and disease processes such as leukemia are less well understood and need further investigation. Splenectomy is the only effective treatment in congenital hemolytic jaundice and in acquired hemolytic anemia; the operation should be carried out promptly in most cases. Transfusion may be used in all varieties of hemolytic disease and is the only effective form of therapy in sickle-cell anemia and paroxysmal nocturnal hemoglobinuria.
