Flashcards in Anemia Deck (12):
1

3 categories of anemia

Microcytic hypochromic
Macrocytic normochromic
Normocytic normochromic

2

Microcytic hypochromic

Thalassemias, bone marrow failure, chronic disease, IDA

3

Microcytic hypochromic

Thalassemias, bone marrow failure, chronic disease, IDA
Low RBC, Hgb/Hct, low MCV and MCHC
High risk for iron deficiency

4

Macrocytic normochrmoic

Drug induced
B12 deficiency (vegans at risk, yo)
Folate deficiency (Alcoholics)

5

Normocytic normochromic

Acute hemorrhage, blood parasites, bone marrow failure, systemic/chronic disease, hemolytic anemias
Low RBC, hgb/Hct, normal indices
MC in ambulatory western patients!
THESE WILL NOT RESPOND TO NUTRITION UNLESS COEXISTENT DEFICIENCY

6

Which conditions can lead to normocytic or microcytic anemia

Bone marrow fakilure: sideroblastic anemia (more often micro)
Chronic diseasE: inflammatory disease, infection, malignant disease

7

DDX and management of the 3 major anemias:
IDA

IDA: r/o GI bleed, then supplement with iron for several months. Avoid ferrous sulfate supplements, non-enteric capsules, increase dietary iron, avoid tea/coffee, serum ferritin

8

DDX and management of the 3 major anemias:

Folic acid deficiency

Folic acid supplements, B12 supplements, serum folate and serum b12 (folic acid masks b12)

9

DDX and management of the 3 major anemias:
Vb12 deficiency

With/without pernicious anema = supplement with b12

10

Substances that inhibit iron absorption (3)
Enhance iron absorption (3)

Enhance: vitamin A, C, betaine HCl
Inhibit: tea, coffee, enteric coated capsules

11

Iron supplement form that causes GI side effects

Ferrous sulfate

12

Effectiveness of b12 supplements orally when malabsorption = cause of b12 deficiency?

Still effective
