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.

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. Polish Academjy of Sciences? Splenectomy usually esferocitoeis in disappearance of anemia and clear amelioration of hemolytic markers.

A combined splenectomy and cholecystectomy may be beneficial in patients with gallstones.

Genetic counseling is recommended in families with a history of HS. HS is caused by mutations in one of the following genes: 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. 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: The high association of Esferocitoxis with both diabetes and iron overload suggest damage of the endocrine pancreas by the latter, as it is also seen in genetic hemochromatosis.
