Q

Why might every other day dosing be better in Iron Deficiency Anemia?

A
  • Hepcidin: iron-regulating peptide in the liver that helps with absorption and transfering
  • within 48 Hours Hepcidin normalizes

26
Q

What is important to know about Folic Acid Deficiency Anemia?

27
Q

What are some of the common Chronic Diseases that could cause Anemia?

A
  • CKD
  • CHF
  • Cancer
  • HIV/AIDS
28
Q

What is the way that CKD could cause Anemia?

A
  • Erythropoietin is made in the kidenys which stimulates the production of RBC
  • Anemia = Decreased Erythropoietin, Chronic Inflammation, Nutritional Issues
29
Q

What are some treatment options for CKD in Anemia?

A
  • AVOID blood transfusion
  • Correct Nutritional Deficiencies
  • ESAs
30
Q

What is important to know about Blood Transfusion in Anemia of CKD?

  • Target is TSAT of 30%
32
Q

What is important to know about ESA in Anemia of CKD?

A
  • Helps prevent blood transfusion
  • DO NOT target NORMAL Hbg
  • Hgb NEEDS to be >10
  • Can cause cardio issues
33
Q

What are some of the treatment options for Heart Failure in Anemia?

34
Q

What is the way that we treat Blood Loss Anemia?

A

  • Acquired: Drug Induced
37
Q

What is important to know about Sickle Cell Anemia?

A
