The purpose of this study is to
1. better characterize the short term and long term natural history of hereditary spherocytosis (HS) including diagnosis, complications, and indications for and response to splenectomy
Patients with a new or established diagnosis of HS seen at Children's Medical Center will be asked to enroll in the study. Previous and current medical records will be reviewed to systematically catalogue their history of HS, including diagnosis, complications, hospitalizations, medications and laboratory data. Health-related quality of life questionnaires will be given to the patients and their parents at enrollment and periodically during the follow-up. Those who agree will have up to three small samples of blood collected and frozen for future laboratory studies of complications associated with HS and/or splenectomy.
We anticipate enrolling approximately 200 children and young adults with HS in this study and following them until adulthood (age 18-21 years).

Hereditary spherocytosis (HS) is the most common inherited hemolytic anemia with heterogeneous clinico-laboratory manifestations. We evaluated the flow-cytometric tests: eosin-5'-maleimide (EMA) and f...
A familial congenital hemolytic anemia characterized by numerous abnormally shaped erythrocytes which are generally spheroidal. The erythrocytes have increased osmotic fragility and are abnormally permeable to sodium ions.
Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.
Hereditary conditions that feature progressive visual loss in association with optic atrophy. Relatively common forms include autosomal dominant optic atrophy (OPTIC ATROPHY, AUTOSOMAL DOMINANT) and Leber hereditary optic atrophy (OPTIC ATROPHY, HEREDITARY, LEBER).
Hereditary inflammation conditions, characterized by recurrent episodes of systemic inflammation. Common symptoms include recurrent fever, rash, arthritis, fatigue, and secondary AMYLOIDOSIS. Hereditary autoinflammatory diseases are associated with mutations in genes involved in regulation of normal inflammatory process and are not caused by AUTOANTIBODIES, or antigen specific T-LYMPHOCYTES.
A form of hereditary angioedema that occurs in women and is precipitated or worsened by high ESTROGEN levels. It is associated with mutations in the gene for FACTOR XII that result in its increased activity.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
