How does celiac disease cause hyposplenism?
Splenic atrophy can occur in coeliac disease and specifically affects the size of the marginal zone and white pulp B-lymphocyte compartment [62], possibly via an autoimmune mechanism. This could lead to IgM memory B-lymphocyte depletion and contribute to hyposplenism.
What causes Autosplenectomy?
The most frequent cause of autosplenectomy is sickle cell anemia which causes progressive splenic hypofunction over time. Increased deoxygenation causes sickling of red blood cells, which adhere to the spleen wall and splenic macrophages causing ischemia.
How is hyposplenism diagnosed?
Hyposplenism is relatively easy to recognize by typical changes observed on the peripheral blood smear; including Howell-Jolly bodies, monocytosis, lymphocytosis, and increased platelet counts. Diagnosis can be confirmed by pitted RBC counts or 99Tc-labelled radiocolloid scan of the spleen; wherever available.

How are Howell Jolly bodies formed?
Howell-Jolly bodies are often seen when there is loss of splenic function as in congenital asplenia, after surgical removal, or in autosplenectomy in sickle cell anemia. They also can be found in hemolytic anemia. pernicious anemia, thalassemia, and leukemia.
What does Asplenic mean?

What is splenic atrophy?
atrophic spleen | splenic atrophy. Definition: acquired diminution of the size of the spleen associated with wasting as from death and reabsorption of cells, diminished cellular proliferation, decreased cellular volume, pressure, ischemia, malnutrition, reduced function or malfunction, or hormonal changes.
What do Heinz bodies indicate?
Heinz bodies are indicative of oxidative injury to the erythrocyte. They are clumps of irreversibly denatured hemoglobin attached to the erythrocyte cell membrane.
What is Holly Jolly bodies?
Howell-Jolly bodies occur where there is no spleen or an non-functioning spleen, referred to as asplenia. They are usually one of these at most in a red cell, round, dark purple to red in color and often located peripherally on the red blood cell.
What is polysplenia?
