Overhydrated Hereditary Stomatocytosis

OHS


Presentation

  • Immunocytochemistry and Western blotting revealed that in OHSt patients, the protein was present in spleen, liver, neutrophils, platelets, monocytes, and about 50% of the peripheral lymphocytes, with the same distribution as in healthy controls.[ncbi.nlm.nih.gov]
  • In erythroid cell cultures from OHSt patients, stomatin-immunoreactivity (stomatin-IR) was present in progenitor cells but remained restricted to the area of the multivesicular complexes and the nucleus in the developing cells and was not seen in the[ncbi.nlm.nih.gov]
  • Leading experts from Latin America, Africa, Near and Middle East, Indian Subcontinent, Far East, Oceania and Australia present their expert insights into specific conditions, as well as progress and challenges in the development of the specialty.[books.google.de]
  • Acronym OHST Synonyms Hereditary, overhydrated, cation-leak stomatocytosis OHS Overhydrated cation leak stomatocytosis Potassium sodium disorder of erythrocyte Keywords Any medical or genetic information present in this entry is provided for research,[uniprot.org]
  • The gene responsible for both dehydrated hereditary stomatocytosis and familial pseudohyperkalemia, a nonhemolytic variant that presents with high plasma K levels, has been mapped to 16q23-qter.[ncbi.nlm.nih.gov]
Malnutrition
  • […] sphercoytes -treatment: splenectomy -acute alcoholism -other causes Acanthocytes (Spurr cells) -small, dense RBCs with a few irregular projections that vary in width, length, and surface distribution -found in severe liver disease, neuroacanthocytosis, malnutrition[quizlet.com]
  • ACANTHOCYTOSIS IN OTHER CONDITIONS A small number of acanthocytes appear in malnutrition resulting from diverse causes, including anorexia nervosa and cystic fibrosis. The red cell shape normalizes after restoration of adequate nutritional status.[medtextfree.wordpress.com]
Pathologist
  • She has published over 100 peer-reviewed publications in the field of haemostasis, is an international expert on platelet testing and aspirin resistance, and has served on review panels from the National Institutes of Health (NIH), College of American Pathologists[books.google.com]
Suggestibility
  • Although no major oxydative stress has been reported in patients with overhydrated hereditary stomatocytosis, we found decreased amounts of oxydized glutathione, creatine and ergothioneine, suggesting transporter abnormalities and/or uncharacterized oxydative[ncbi.nlm.nih.gov]
  • This strongly suggests that these alterations are related to the young age of RBCs in these 2 hemolytic anemias.[haematologica.org]
  • […] ascorbate metabolisms (accumulation of ascorbate metabolism intermediates such as diketogulonic acid and decreased levels of both glutathione and glutathione disulfide), in markers for membrane lipids turnover such as carnitine, in some amino acids (suggesting[labex-grex.com]
  • These results suggest that formation of the hairpin loop is inefficient and that the conserved proline residue is indispensable for formation of the hairpin loop.[biochemj.org]
