- General Discussion
-
- ** REMINDER **
- The information contained in the Rare Disease Database is provided for
- educational purposes only. It should not be used for diagnostic or treatment
- purposes. If you wish to obtain more information about this disorder, please

- section of this report.

-
- Hereditary Non-Spherocytic Hemolytic Anemia is thought to be a
- heterogenous group of disorders characterized by intrinsic red blood cell
- defects. Hereditary enzyme defects such as glucose-6-phosphate dehydrogenase
- deficiency (G-6-PD), pyruvate kinase deficiency or Favism may produce this
- disorder. The spheroid shaped red cells known as spherocytes which are found
- in the blood of patients with Hereditary Spherocytic Hemolytic Anemia are not
- present in this disorder.
-
- Symptoms
-
- The symptoms of Hereditary Non-Spherocytic Hemolytic Anemia include moderate
- anemia, intermittent jaundice and occasionally an enlarged spleen. The onset
- is usually during childhood. However, some patients may be jaundiced at
- birth. A non-spherocytic hemolytic anemia may be suspected at this time if
- small granules known as Heinz bodies are present in the red blood cells.
-
- Hemolysis may be a reaction to stress, during which time the patient may
- experience fever, jaundice, or possibly an enlarged spleen or liver. A
- hemolytic crisis may be precipitated by the use of certain drugs such as
- phenacetin, some sulfonamides, or antimalarials.
-
- Causes
-
- Hereditary Non-Spherocytic Hemolytic Anemia is probably a group of related
- disorders rather than a single entity. One cause is a deficiency of G-6-PD
- transmitted as a partially dominant trait in the sex chromosome.
-
- Therapies: Standard
-
- Blood transfusions may occasionally be a necessary treatment for this defect.
- While splenectomy is beneficial in the treatment of hereditary hemolytic
- anemias of the spherocytic type, it is of no benefit in the non-spherocytic
- kind of hereditary hemolytic anemias. Iron chelation therapy (e.g.,
- desferoxamine) may be necessary if a chronic blood transfusion program
- becomes necessary.
-
- Therapies: Investigational
-
- Studies are being conducted in the use of Sandoglobulin as a treatment
- for Hereditary Non-Spherocytic Hemolytic Anemia. Further investigation is
- needed to determine it's safety and effectiveness.
