The erythrocytes' cell membranes may abnormally 'leak' sodium and/or potassium ions, causing abnormalities in cell volume. [1] Hereditary stomatocytosis should be distinguished from acquired causes of stomatocytosis, including dilantin toxicity and alcoholism, as well as artifact from the process of preparing peripheral blood smears.

It is a rare disease in dogs, with cats seven to ten times more likely to be infected. The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system. [20] Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10% ...
The underlying causes of hemolytic jaundice, as its name suggests, are disorders associated with hemolysis. Such disorders are manifold and the common causes include: Blood smear of a patient with sickle cell disease. The characteristic sickle-shaped appearance of red blood cells can be observed.
The mutation which causes sickle cell disease results in an abnormal hemoglobin known as hemoglobin S (HbS), which replaces HbA in adults. [20] The human genome contains a pair of genes for β-globin; in people with sickle cell disease, both genes are affected and the erythropoietic cells in the bone marrow will only create HbS.
Autosplenectomy caused by sickle cell anemia or hyposplenism in coeliac disease [3] In patients with obstructive liver disease, lecithin cholesterol acetyltransferase activity is depressed, which increases the cholesterol-to-phospholipid ratio and produces an absolute increase in the surface area of the red cell membrane.
Diagnosis is made by first ruling out other causes of hemolytic anemia, such as G6PD, thalassemia, sickle-cell disease. Clinical history is also important to elucidate any underlying illness or medications that may have led to the disease. [citation needed] Laboratory investigations are carried out to determine the etiology of the disease.
Atypical HUS (aHUS) represents 5–10% of HUS cases [5] and is largely due to one or several genetic mutations that cause chronic, uncontrolled, and excessive activation of the complement system, [5] which is a group of immune signaling factors that promote inflammation, enhance the ability of antibodies and phagocytic cells to clear microbes ...
HbC can combine with other abnormal hemoglobins and cause serious hemoglobinopathies. Individuals with sickle cell–hemoglobin C (HbSC), have inherited the gene for sickle cell disease (HbS) from one parent and the gene for hemoglobin C disease (HbC) from the other parent. Since HbC does not polymerize as readily as HbS, there is less sickling ...
