The cause may be intrinsic or extrinsic in nature. Causes of intrinsic hemolytic anemia include inherited defects in red blood cells, such as hereditary spherocytosis
Newborn infants who have hereditary spherocytosis (HS) can develop anemia and hyperbilirubinemia. Bilirubin-induced neurologic dysfunction is less likely in these neonates if the diagnosis of HS is recognized and appropriate treatment provided. Among neonates listed in the USA Kernicterus Registry, HS was the third most common underlying hemolytic condition after glucose-6-phosphate dehydrogenase deficiency and ABO hemolytic disease.

• MCV. • MCH. • MCHC Keywords: Hereditary spherocytosis, Cryohemolysis, Erythrocyte osmotic fragility The mean cell volume (MCV) decreases slightly and the MCHC increases as 14 Aug 2015 It has been observed that the difference between mean corpuscular volume ( MCV) and MSCV is higher in the cases of hereditary spherocytosis The morphological approach uses MCV to classify anemia as microcytic, normocytic, Hereditary spherocytosis (HS) is due to an abnormality in the erythrocyte inside the red cells, such as in hereditary or autoimmune spherocytosis. Mean corpuscular volume (MCV) is a measurement of the average size of your RBCs. RBC number; Mean Corpuscular Volume (MCV); Hemoglobin (Hg). The calculated The red cell indices (MCV, MCH, MCHC) can also be calculated by using the following formulae: MCV = HCT x 10 Hereditary spherocytosis.
In hereditary spherocytosis, because RBCs are spheroidal and the mean corpuscular volume (MCV) is normal, the mean corpuscular diameter is below normal, and RBCs resemble microspherocytes. The mean corpuscular hemoglobin concentration (MCHC) is increased.
MICROCYTOSIS: Low MCV (mean corpuscular volume) under 80. MCV = mean cell volume Spherocytes: (helmet cells) hereditary spherocytosis, thermal.

A sick febrile child is admitted with severe pallor, typically with a maculopapular rash on the cheeks (‘slapped cheeks’), and often with diarrhoea and vomiting. 2004-04-15 · Significant QTL were identified for the MCV trait only, suggesting that RBC membrane characteristics are a target for modifier gene action. The most significant quantitative trait locus, Hsm1 (hereditary spherocytosis modifier 1), localizes to mouse Chromosome 12 and is dominant.

aplastic crisis in patients with hereditary spherocytosis (and other Hemolytic disorders). Transient aplastic crisis Persons with decreased erythrocytes caused by conditions such as iron deficiency anemia, human immunodeficiency virus sickle cell disease, spherocytosis or thalassemia are at risk of transient aplastic crisis if infected with parvovirus B19.
Hereditary spherocytosis is a condition that affects red blood cells. People with this condition typically experience a shortage of red blood cells (), yellowing of the eyes and skin (jaundice), and an enlarged spleen (splenomegaly).

Spherocytosis most often refers to hereditary spherocytosis. This is caused by a molecular defect in one or more of the proteins of the red blood cell cytoskeleton , including spectrin , ankyrin , Band 3 , or Protein 4.2 .
Hereditary spherocytosis (HS) is a common red blood cell disorder. It has been shown that the mean sphered corpuscular volume (MSCV), an artificial volume, is always lower than the MCV in HS and also in some autoimmune haemolytic anaemia (AIHA). Hereditary spherocytosis is characterized by hemolysis of spheroidal RBCs and anemia.

Hereditary spherocytosis (HS) was described in 1871 and the first recorded splenectomy was performed soon after. It is the commonest cause of inherited chronic haemolysis in Northern Europe and North America with a quoted incidence of 1 in 5000 births (Morton et al, 1962).However, studies of osmotic fragility in blood donors suggest the existence of extremely mild or subclinical forms (Godal

In most cases, it is an autosomal dominant disease that is caused by red blood cell ( RBC ) membrane protein defects, which render the RBCs more vulnerable to osmotic stress and hemolysis .
