Esferocitosis hereditaria: aspectos clínicos, bioquímicos y moleculares

The development of new techniques allowed finding out the first biochemical alterations in erythrocyte membrane proteins and later on, the recombinant DNA techniques made possible to detect molecular alternations. Red cell morphology, osmotic resistance, hypertonic cryohemolysis test, eosinmaleimide binding in flow cytometry, sodium dodecyl sulfate-poly acrylamide gel electrophoresis and ektacytometry are all used to diagnose HS.

HS is a very heterogeneous disease caused by an intrinsic defect of red cells; there are other secondary disorders to this affection. Este hecho explica la discrepancia entre estos valores.

August – September Pages ee78 Pages Four HS categories have been identified: Treatment involves management of jaundice phototherapy and even exchange blood transfusion to prevent hyperbilirubinemic encephalopathy and RBC transfusions in case of severe, symptomatic anemia. Applying criteria such as permanence of an increased percentage of spherocytes, family history, biochemical symptoms of hemolysis and clinical data, we claim a prevalence of generally asymptomatic hereditary spherocytosis HS of 1: Subscriber If you already have your login data, please click here.

A combined splenectomy and cholecystectomy may be beneficial in patients with gallstones. Rare complications include poor growth, skin ulceration, chronic dermatitis, high output heart failure, and secondary iron overload. Management and treatment Treatment involves management of jaundice phototherapy and even exchange blood transfusion to prevent hyperbilirubinemic encephalopathy and RBC transfusions in case of severe, symptomatic anemia.

Folate supplement is recommended particularly after esferoctiosis events. For intermediate categories the indication is less clear, being useful in moderate cases before puberty.

The treatment of choice in HS is splenectomy, since this is the most effective method in the control of anemia, although red cell survival is still short and spherocytes do not disappear. The most used test for diagnosing HS is the osmotic fragility of the red cell. Esferocitosid usually results in disappearance of anemia and clear amelioration of hemolytic markers.

Defects in these proteins lead to a loss in RBC membrane cohesion and membrane surface area, resulting in erythrocyte sphering, decreased deformability and premature destruction in the spleen. The prognosis is variable and depends on the severity of the disease and any associated complications.
