How Spherocytes are formed?

Spherocytes are formed when there is loss of part of the red blood cell membrane. This may occur in the setting of immune-mediated hemolysis or congenital red cell membrane defects such as hereditary spherocytosis. Spherocytes are smaller than normal red blood cells and lack central pallor.

How do you identify Spherocytes?

Spherocytes are found on the blood film, usually accounting for 15% to 20% of cells. The presence of spherocytes in the blood can be confirmed by an osmotic fragility test (however the osmotic fragility test is not specific for hereditary spherocytosis and may be abnormal in immune and other hemolytic anemias).

What is PB morphology?

A blood smear, also referred to as a peripheral smear for morphology, is an important test for evaluating blood-related problems, such as those in red blood cells, white blood cells, or platelets.

What are Spherocytes?

Spherocytes are red blood cells that are sphere-shaped rather than the usual round doughnut shape. Spherocytes are more fragile than normal red cells and their presence is accompanied by anemias of varying severity.

Can Spherocytosis be cured?

Treatment options There is no cure for HS, but it can be treated. The severity of your symptoms will determine which course of treatment you receive. Options include: Surgery: In moderate or severe disease, removing the spleen can prevent common complications that result from hereditary spherocytosis.

Why is Spherocytosis bad?

These spherocytes are abnormal, fragile and possess a short lifespan as compared to normal red blood cells. The cells tax the ability of the spleen to clear out abnormal red cells and their products, and this can result in an enlargement of the spleen (splenomegaly) and gallbladder disease problems.

How is spherocytosis treated?

The treatment for hereditary spherocytosis is individualized and may require transfusions, folic acid administration, full or partial splenectomy, and/or cholecystectomy. Complications of spherocytosis may include megaloblastic crisis, low folic acid levels, splenomegaly, and/or gallbladder problems.

Is spherocytosis autoimmune?

Spherocytosis may be present in autoimmune hemolytic anemia in which autoantibodies react with red blood cells and cause alterations in their membranes that includes lysis of red blood cells. Spherocytes may develop during this destruction of red blood cells.

What is platelet morphology?

Platelets are very small non-nucleated cells with fine granules that derive from fragmentation of megakaryocytes.

Is spherocytosis a blood disorder?

Hereditary spherocytosis is an inherited blood disorder. It happens because of a problem with the red blood cells (RBCs). Instead of being shaped like a disk, the cells are round like a sphere. These red blood cells (called spherocytes) are more fragile than disk-shaped RBCs.

Why are spherocytes darker than normal red blood cells?

Cells often appear darker and smaller than a normocytic red blood cell. 1 Formation of spherocytes in circulation occurs due to a partial loss of the red blood cell membrane.

What are the signs of non hereditary spherocytosis?

A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production, and decreased hemoglobin and hematocrit. The term “non-hereditary spherocytosis” is occasionally used, albeit rarely.

What causes the erythrocytes to be spherical in shape?

Spherocytosis is one of the most common inherited hemolytic anemias. It is caused by a defect in the erythrocyte membrane, which leads to an increased permeability for sodium and water, giving the erythrocyte its characteristic spherical form. This renders the erythrocytes susceptible to phagocytosis in the spleen at an early age.

What does CBC mean in relation to spherocytosis?

A complete blood count (CBC) may show increased reticulocytes, a sign of increased red blood cell production, and decreased hemoglobin and hematocrit. The term “non-hereditary spherocytosis” is occasionally used, albeit rarely. Spherocytosis most often refers to hereditary spherocytosis.
