It is the most common inherited anemia in individuals of northern European descent, affecting approximately 1 in 1000–2500 individuals depending on the diagnostic criteria. Se hela listan på emedicine.medscape.com The hereditary xerocytosis (HX) syndromes are the most common primary disorder of erythrocyte hydration and are the most clinically heterogeneous (Table 1). 31 HX erythrocytes are dehydrated due to a cation leak, primarily of potassium, that leads to decreased potassium concentration. He ordered a blood test to check for it, and after receiving the results referred me to a hematologist. Sure enough, I have Hereditary Spherocytosis Hemolytic Anemia. What is Anemia?

1.1 Organisation of red blood cell membrane The human red cell membrane consists of an outer lipid bilayer (cholesterol and phospholipids) and an inner layer of cytoplasmic spectrin-based cytoskeleton It is a disorder that causes red blood cells to have spherical shapes instead of flattened discs that curve inward. In a healthy body, the spleen begins the response of the immune system to infections. The spleen filters bacteria and damaged cells out of the bloodstream. However, spherocytosis makes it difficult for red blood cells to cross the spleen due to the shape and stiffness of the Hereditary Spherocytosis (HS) is a disorder of the red cell membrane inherited usually in an autosomal dominant pattern. In this condition, the red cells are more rigid and fragile than normal. They are spherocytic in shape appearing small and deeply stained on blood smears and have osmotic fragility.

This makes the cells become rounder, like spheres.
