Anemia - Rogers Flashcards
what are symptoms of anemia
exertional dyspnea, angina, tachycardia, fatigue, pallor
what is a normal Hgb value for males?***
> 13.5 g/dL
What is a normal Hgb value for females?***
> 12 g/dL
What is a normal MCV?
80-100 mm3
what are the microcytic anemias?
iron deficiency, sickle cell, thalassemia
what are the normocytic anemias?
chronic disease, blood loss, hemolysis
what are the macrocytic anemias?
folic acid and/or B12 deficiency
what are the characteristics of iron deficient anemia?
decreased Hgb
decreased MCV
decreased ferritin and serum iron
decreased TSAT
what is the normal value range for ferritin?
15-200 mg/dL (decreased in iron deficiency)
what is the normal range for TSAT
20-50% (decreased in iron deficiency)
treatment of iron deficient anemia
oral iron preferred
exceptions: cannot tolerate, cannot absorb, ESRD, heart failure (then IV iron)
address underlying cause
doing for oral iron
65mg elemental QOD
OR
120-200mg elemental daily (BID or TID)
concentrations of oral iron
ferrous gluconate (10%), ferosul (20%), fumarate (33%)
characteristics of B12 anemia
decreased Hgb
increased MCV
decreased serum B12
B12 deficiency treatment
IM or SQ
100-1000 daily, weekly, or monthly
Oral
1000-2000 mcg/day
water soluble vitamin
drugs that cause B12 deficiency
PPIs, Metformin
characteristics of folic acid deficiency
decreased Hgb
increased MCV
decreased serum folate (<10 ng/mL)
medications that can cause folic acid deficiency
methotrexate, phenytoin, sulfasalazine, bactrim
treatment for folic acid deficient anemia
1-5mg daily until Hgb normalizes (most commonly 1mg)
- always check vitamin B12 too!
how to treat anemia of CKD
- avoid blood transfusions
- supplement folate and B12
- oral or IV iron
- Target TSAT >30%
- Use ESAs minimum dose to target Hgb>10
- only start ESAs after replenishing iron
Heart failure and anemia treatment
treat with iron infusions (IV)
- decreased HF hospitalizations
- did not improve overall survival
- No benefit from oral iron
- do not use ESAs
treatment for blood loss anemia
transfuse with packed red blood cells when Hgb <7
How much elemental iron does a unit of packed red blood cells contain?
250mg
treatment for sickle cell anemia
- 1mg/day folic acid
- blood transfusions
- hydroxyurea (10-15mg mg/kg/day\
- immunizations and pain control
