Blood reviews

Sickle cell anaemia is a hereditary disorder commonly seen in the black population, due to a point mutation in the beta globin gene. The sickle mutation is responsible for an increased rigidity and adherence of the red blood cell leading to haemolytic anaemia and vaso-occlusive episodes. Symptoms include dactylitis, painful crisis, splenic sequestration and the development of multi-organ damage and failure. ⋯ The patient is now cured of both the sickle cell anaemia and the leukemia. Since April 1986, 21 patients underwent an allogeneic bone marrow transplantation for sickle cell anaemia in our department. 20 patients became asymptomatic and have an electrophoretic pattern of the haemoglobin similar to that of the donor. One patient died of bone marrow transplantation related complications.
