How is hereditary Stomatocytosis diagnosed?
The combination of macrocytosis and a low MCHC is virtually diagnostic of hereditary stomatocytosis, especially when stomatocytes are present on the peripheral blood smear and the osmotic fragility test is positive.
What causes Stomatocytosis?
Most cases of stomatocytosis are due to alteration in permeability, leading to an increase in red cell volume. Stomatocytes form at a low blood acidic pH, as seen in exposure to cationic detergents and in patients receiving phenolthiazine or chlorpromazine. Stomatocytosis can be an inherited or acquired condition.
What is hereditary Stomatocytosis?
Hereditary stomatocytosis (HSt) and hereditary xerocytosis (HX) are rare disorders that present with various degrees of hemolytic anemia and abnormal red blood cell (RBC) morphologies. Both disorders are characterized by alterations in RBC hydration.
What causes hereditary Elliptocytosis?
Hereditary elliptocytosis is caused by a genetic change in either the EPB41, SPTA1, or SPTB gene , and is inherited in an autosomal dominant pattern. Hereditary pyropoikilocytosis is a related condition with more serious symptoms, and is inherited in an autosomal recessive pattern.
How is Stomatocytosis treated?
Treatment. At present there is no specific treatment. Many patients with haemolytic anaemia take folic acid (vitamin B9) since the greater turnover of cells consumes this vitamin. During crises transfusion may be required.
What are the symptoms of hereditary Stomatocytosis?
Most adult patients present a mild anemia or a totally compensated hemolysis, with fatigue, icterus, splenomegaly and risks of secondary complications including cholelithiasis. Patients can also be referred for unexplained hemochromatosis, since iron overload is frequently associated with the disease.
What does the presence of stomatocytes mean?
Stomatocytes are red blood cells that, under a microscope, look like “kissing lips” or “coffee beans” rather than a biconcave disc with a clear centre. A significantly high number of stomatocytes can be found in alcoholism, liver and gallbladder disease, cancer and heart disease.
What are the symptoms of hereditary elliptocytosis?
Hereditary elliptocytosis (HE) refers to a group of inherited blood conditions where the red blood cells are abnormally shaped. Symptoms vary from very mild to severe and can include fatigue, shortness of breath, gallstones, and yellowing of the skin and eyes ( jaundice ).
What are the side effects of a kidney infection?

What are the symptoms of a failing kidney?
Failing kidneys don’t remove extra fluid, which builds up in your body causing swelling in the legs, ankles, feet, and/or hands.
Can a dry skin be a sign of kidney disease?
