Plasma vitamin E levels in a chronically hemolyzing group of dialysis patients
Abstract:
Plasma vitamin E levels and the ascorbate cyanide test were assessed in 15 chronic hemodialysis (HD) patients (group A) exposed to persistently elevated chloramine levels in the dialysis water. The vitamin E levels in these patients, who had evidence of oxidant induced hemolytic anemia, were compared to 15 chronic HD patients exposed to low chloramine levels (group B) and 17 controls (group C). Vitamin E levels were found to be significantly lower in group A than in either groups B or C (p less than 0.001). Within group A, levels were lower in those patients who had a positive ascorbate cyanide test (p less than 0.05). Upon removal of chloramines from the dialysis water, vitamin E levels in group A were no longer significantly different from those found in groups B or C.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
EPO then...
Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
