Anemia is a common complication of end-stage renal disease (ESRD). Anemia occurs when there is a shortage of red blood cells or when the red blood cells are not correctly formed. In dialysis units, anemia is usually measured by the hematocrit blood test, which reports the percentage of the blood that is comprised of red blood cells. Normally, a hematocrit is from 37% to 47% for women and from 42% to 52% for men. Without interventions, a dialysis patient's hematocrit usually stabilizes between 20-25%. At this level, most patients tire easily and feel drained of energy. Several statistical analyses have shown that dialysis patients have signficantly more complications, hospitalizations, and a higher mortality rate when their hematocrit is below 30% (approximately).

Dialysis patients experience anemia (low hematocrit) primarily because their kidneys no longer produce adequate amounts of erythropoietin (EPO). EPO is the principal factor that stimulates red blood cell production in the bone marrow.

Before 1990, most dialysis patients experienced moderate to severe anemia on a long-term basis. At that time, dialysis patients were given frequent blood transfusions which also exposed them to possible infection by bloodborne pathogens such as hepatitis viruses and HIV. Today, thanks to the availability of bioengineered EPO, the need for most transfusions has been eliminated.

With most patients now routinely receiving EPO during their dialysis treatments, hematocrits are routinely in the range of 30-36%. The NKF-DOQI recommended target hematocrit range for dialysis patients currently is 33% to 36%. Most insurance companies and Medicare will not reimburse the dialysis facilities for EPO injections when the patient's hematocrit is above a certain number (36% approximately).

The production of healthy blood cells is also dependent on the body having enough iron, vitamin B12, folic acid and other substances. If a patient does not respond to EPO therapy, the most likely cause is a deficiency of iron. For this reason, most dialysis centers routinely monitor iron levels in the blood.

Warning:  Changes should never be made in a patient's treatment or care based solely on the information found here.  Every patient has unique healthcare concerns and considerations and all these factors must all be taken into account before any changes can be safely made.  All medical and therapeutic decisions must come from a qualified health care provider.  Read RenalWEB's Legal Disclaimer before proceeding.

"The failure to simultaneously force the companies to reeducate the renal physician community was disappointing. There's mounting evidence that high doses of ESAs in renal disease patients is associated with increased risk of heart attacks, strokes and earlier mortality. Many of these patients are poor and unaware of the quality of care they receive at dialysis centers. They, just as much as cancer patients, need to be informed about the risks posed by overuse of ESAs."
