Anemia Flashcards
What is Anemia?
- Decreased RBC or Hbg
What are some of the signs and symptoms of Anemia?
- SOB, Chest Pain,Tachycardia, Fatigue, Paleness, Asymptomatic
What are some of the important bloodwork values that we should know for Anemia?
- RBD: 4.5-5.5 x10^6 u/L [M] & 4.1-4.9x10^6 cells/uL [F]
- Hgb: 13.5-18 g/L [M] & 12-16 g/dL [F]
- Hct: 38-50% [M] & 36-46% [F]
- MCV: 80-100 mm^3
- MCH: 26-34 pg/cell
- MCHC: 31-37 g/dl
- RDW: 11.5-14.5%
Is Iron Supplementation the first line treatment in Anemia?
- NO - it depends on the case
What are some of the causes for Anemia?
- Decreased RBC production [chronic diseases or nutritional deficiencies]
- Increased RBD destructinon [Drugs or Sickle Cell]
- Increased RBC Loss [blood loss or NSAIDS/ASA]
What are the classifications of Anemia?
- MICRO: MCV < 80 [Iron deficiency, Sickle Cell]
- NORMAL: MCV 80-100 [Chronic Disease, Blood Loss]
- MACRO: MCV > 100 [Folic Acid, B12]
What is the classification of Iron Deficiency Anemia?
- Decreased Hgb
- Decreased MCV
- Increased or Normal RDW
- Decreased Ferritin
- Increased TIBC
- Normal or Decreased Iron
- Decreased TSAT
What are some of the important values for Iron Studies in Iron Deficiency Anemia?
- Ferritin: 15-200ng/mL [Really <45]
- Iron: 40-160 mcg/dL
- Transferrin: 200-260 mg/dL
- TIBC: 250-400 mcg/dL
- TSAT: 20-50%
What is important to know about Ferritin within the Iron Studies in Iron Deficiency Anemia?
- Anything <45 really is a deficiency
- Inflammation or Chronic Disease gives a false positive
What are some of the causes for Iron Deficieny Anemia?
- Blood Loss [menstration, donating]
- Decreased Absorption
- Vegetarian Diet [Heme from meat or Non-Heme from dairy or plants]
- Increased Consumption [Pregnancy]
Can drugs cause Iron Deficieny Anemia?
- NO - Drugs dont really cause any iron anemia
What are some of the addintional Signs and Symptoms ONLY for Iron Deficiency Anemia?
- Spoon-shaped Nails
- Inflamed Tongue
- Pica [craving things with NO nutritional value]
What is the treatment of Iron Deficiency Anemia?
- ORAL Iron [elemental iron]
- Either 65mg every other day OR 120-200mg per day
- 3-6 months to replete stores
When wouldn’t Oral Iron be used in Iron Deficiency Anemia and what would you use?
- If they cant tolerate, cant absorb, ESRD, HF
- Would switch to IV
Why might every other day dosing be better in Iron Deficiency Anemia?
- Hepcidin: iron-regulating peptide in the liver that helps with absorption and transfering
- within 48 Hours Hepcidin normalizes
