ANEMIA PART 1 Flashcards
found in: thalassemia & severe iron deficiency anemia
MICROCYTIC HYPOCHROMIC
means without blood
Anaimia
Causes of Anemia
› Destruction of RBC
› Blood loss
› End-stage renal disease
› Metabolic disorders
Skin : Physical Examination of Anemia
Palor/Pale, Jaundice & Petechiae
Enzyme deficiency
a. G6PD deficiency
b. Pyruvate kinase deficiency
c. Porphyria - problem in heme synthesis
Membrane Defect : Intracorpuscular Abnormality
a. hereditary spherocytosis
b. hereditary elliptocytosis
c. hereditary pyropoikilocytosis
d. hereditary stomatocytosis
e. hereditary acanthocytosis
f. hereditary Rh null disease
decrease of all erythrocyte indices: MCV, MCH & MCHC
MICROCYTIC HYPOCHROMIC
Chemical and Physical Agents under Extracorpuscular Abnormalities
drugs, toxins & burns
Anemia due to Blood Loss
- Acute post hemorrhagic anemia
- Chronic post hemorrhagic anemia
Laboratory Test for Anemia Assessment
- CBC
- Reticulocyte count
- Peripheral smear
- Bone marrow examination
- Iron studies
- Blood Chemistry (KFT, LFT)
- Urinalysis
- Fecalysis
- Hematological special test procedures
Enzyme Deficiency
a. G6PD deficiency
b. Pyruvate kinase deficiency
c. Porphyria
decrease in the oxygen carrying capacity of the blood.
ANEMIA (functional definition)
Anemia Due to Decreased Production of RBC (9 possible answers)
- Iron Deficiency Anemia
- Anemia due to Chronic Inflammation
- Sideroblastic Anemia
- Megaloblastic Anemia
- Aplastic Anemia
- Thalassemia
- Anemia due to Chronic Renal Failure
- Anemia due to Endocrine Disorder
- Anemia due to Marrow Infiltration
Infection under Extracorpuscular Abnormality
- Malaria
- Babesia

Globin Abnormalities
Hemoglobinopathies
(Hb SS, CC, SC)
Mechanical Extracorpuscular Abnormality
a. Microangiopathic hemolytic anemia (MAHA)
1. thrombotic thrombocytopenic purpura
2. hemolytic uremic syndrome (HUS)
b. Traumatic cardiac hemolytic anemia
Morphological Classification of Anemia
- Microcytic hypochromic anemia
- Macrocytic normochromic anemia
- Normocytic normochromic anemia
Increased need of iron
- infancy, childhood, adolescence
- pregnancy
Causes of chronic blood loss
- Heavy menstrual bleeding
- GI bleeding from ulcers or tumors
- Urinary tract with kidney stones
- Iatrogenic cause
Koilonychia, a condition also
referred to as
Spoon-shaped nails
can result in a painless, smooth,
shiny, and reddened tongue
Iron deficiency
develop when the incorporation of iron
into heme is blocked.
Sideroblastic Anemia
due to a congenital enzyme defect delta
amino-levulinic acid synthetase or heme
synthetase
Hereditary Sideroblastic Anemia
due to somatic mutation of the erythroid
progenitor cells that cause either defects in heme synthesis or defects in DNA synthesis
Primary Acquired Sideroblastic Anemia
