Pathologist
Chemical pathologists have noted that plasma-W] levels among a standard population are generally lower in hot weather (the normal range in Barbados is lower than that in the UK),30-32 and this net movement of K into cells at 37 degC can explain it. [the-medical-dictionary.com]

Treatment There is no specific treatment for Hereditary Stomatocytosis, but some patients who have the disorder take folic acids, a water-soluble vitamin, because most of these cells use this vitamin. [hereditarystomatocytosiskw.weebly.com]
The goal of treatment is to develop a butyrate-based treatment regimen that can maintain at least 4-8% gamma globin synthesis, 70% F-cells, and 25% Hb F or more in the peripheral circulation. [grantome.com]

Prognosis
Prognosis Some clinical problems in Hereditary Stomatocytosis are mild enough to let the patient live a normal life. Although Gallstones can be a problem, that can be easily fixed with a surgery. [hereditarystomatocytosiskw.weebly.com]
THERAPY, COURSE, AND PROGNOSIS The majority of hydrocytosis patients suffer from significant lifelong anemia. [medtextfree.wordpress.com]
Although the fluid can cause trouble and much concern, it resolves spontaneously after delivery and carries a good prognosis. [ucl.ac.uk]
What should you tell the patient and the family about prognosis? The natural histories of hereditary stomatocytosis and hereditary xerocytosis are not well understood. [cancertherapyadvisor.com]
Acanthocytes have long, rigid projections and become entrapped and hemolyzed in the spleen, which results in a rapidly progressive anemia of moderate severity, splenomegaly, and jaundice. 4, 13 Spur cell anemia in end-stage liver disease has a poor prognosis [doctorlib.info]
