Anemia part 1 Flashcards
Iron Treatment Targets
Oral Iron Target:
150-200 mg per day of elemental iron (Approximately 2 to 5 mg of iron per kilogram of body weight per day)
Typically trialed for _________
1-3 months
IV Iron Target
Initial course of IV iron amounting to approximately 1000 mg; this may be repeated
if an initial dose fails to increase Hb level
Repeat labs in ___________
1 week
Should be testing iron status at least every __________
3 months
When prescribing iron therapy, balance the potential beneift of avoiding or minimizing _________ transfusions, ______ therapy and anemia related symptoms against the risk of harm in individual patients
blood transfusions
ESA
For adults CKD patients w/anemia not on iron or ESA theray we suggest a __________of IV iron (or in CKD ND pts alternatively a 1-3 month trial of oral iron therapy if
an increase in Hb concentration without starting ESA treatment is desired and TSAT is more than or equal to 30% and ferritin is more than or equal to 500ng/ml
trial
For CKD ND patients who require iron supplementation, select the route of iron administration based on the oral or IV iron therapy, availability of venous access, response to prior oral iron therapy, side effects with prior oral or IV iron therapy, patient compliance, and cost
ESAs are used in chronic kidney disease but also used in what other type of pts?
cancer pts and oncology pts
Erythropoietic-Stimulating Agents (ESAs)
Glycoproteins that have the same biologic activity as endogenous erythropoietin
Binds to and activates the erythropoietin receptor to stimulate erythropoiesis
Used to maintain _________ levels often after receiving iron therapy
Prevent _________ transfusions
Often increase iron demands for CKD patients
hemoglobin
prevent blood transfusions
ESAs are given Subcutaneous and given in the abdomen
Darbepoetin alfa is used in oncology pts
Epoetin alfa-epbx(Retacrit) is a biosimilar and its cheaper than Epoetin alfa (Procrit)
ESAs like epoetin alfa (procrit), Epoetin ala-epbx (Retacrit), Darbepoetin alfa (Aranesp), and Methoxy polyethylene glycol-epoetin beta (Miracera) are **weight based doing, administerded subcutaneous or IV
Epoetin alfa-epbx (Retacrit) is a biosimilar
minimal availability of multi use vials
availability in our clinic is only single use vials
insurances may begin to push to utilize this biosimilar to decrease costs
There’s a black box warning for Epooetin alpha (procrit) that increases risk of death, myocardial infarction, stroke, venous thromboembolism, thrombosis of vascular access
Thrombosis of vascular access means what? At IV access you can develop blood clotting, port that patient has, dialysis access sites,fistulas or cracks
In the use of epopoetin alfa (procrit) use the lowest dose effective dose is important and we should be look at a hemoglobin target under 11
any pt with that has chronic kidney disease has increased risk of cardiovascular complications
With this medication we are not going to get somebody who has chronic kidney disease to a level of hemoglobin that is on par with the general population we are never correcting their anemia from like a lab based perspective with these agent and the intent is to get their hemoglobin level up high enough so they feel better but its never going to be perfect because of the risk associated with the black box warning
Don’t overshoot a target because of the black box warning
What is the normal hemoglobin value for pts w/o anemia? it
If pt is less than 13 then pt has anemia especially our male pts
If you give pt more procrit their hemoglobin level is going to go higher so its dose-related response
