Abstract

Subjects with a variety of enteropathies, hemolytic anemias, acute respiratory distress syndrome, hepatitis, Gaucher's disease as well as those on TPN and hemodialysis, often have low ("deficient") blood levels of vitamin E. A deficiency of vitamin E can be manifested by accelerated red blood cell destruction and neuromuscular deficit. Supplementation of these patients may be advisable. Neurological dysfunction has been observed in adults with prolonged vitamin E deficiency resulting from lipid malabsorption. Long-term treatment with high doses of vitamin E results in improvement. Administration of 800 IU/day of vitamin E to subjects with G6PD deficiency, sickle-cell anemia and beta-thalassemia has resulted in improvement of hematological parameters. Supplementation with 300 IU/day for 3-6 months has resulted in improved walking distances and improved blood flow in patients with intermittent claudication. In a limited number of controlled studies, 300-600 IU/day resulted in improvement in premenstrual syndrome, tardive dyskinesia and also arthritis. Epidemiological studies suggest that high levels of serum vitamin E are associated with lower risk of certain cancers, cardiovascular disease and infections. In some cases the high ...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
