Ch. 13 Hematopoietic Disorders and Classification of Anemia Flashcards
Bone marrow samples can be HYPERcellular or HYPOcellular of one cell type or all cell types. Define hyper and hypocellular
increased cellularity
decreased cellularity
Define aplastic
when all blood cell types are decreased or absent int the bone marrow
What are the 4 inflammatory conditions that may be evident when examining bone marrow?
- Fibrinous
- Chronic
- Chronic granulomatous
- Chronic pyogranulomatous
What is fibrous inflammation?
involved the infiltration of the bone marrow within FIBRIN exudate without the presence of inalmmatory cells
What is chronic inflammation?
a hyperplastic condition characterized by increased PLASMA cells, mature LYMPHOCYTES, and MAST cells
What is chronic granulomatous inflammation?
characterized by increased MACROPHAGES
What is chronic pyogranulomatous inflammation?
characterized by increased macrophages with the presence of neutrophils
What are the 2 classifications of neoplastic disorders of hematopoiesis?
Lymphoproliferative
OR
Myeloproliferative
What is the common term used to describe neoplastic blood in bone marrow?
Leukemia
What is the function of RBCs?
to transport hemoglobin (oxygen)
According to bone marrow response, anemia is classified as either ______ or _______
regenerative
or
non-regenerative
Typically, the bone marrow responds to anemia by releasing immature RBCs to combat it. By looking at a blood smear and counting young RBCs, anemia can be classified as regenerative or non-regenerative. True or False?
True
What animal rarely releases reticulocytes? What testing therefore usually needs to be done to classify anemia?
Horses
Bone marrow evaluation
Reticulocytes are absent in patients with non-regenerative anemia. True or False?
True
Iron deficiency, Ehrlichiosis, drug toxicity, histoplasmosis, hypothyroidism, and renal insufficiency are common causes for __________ anemia
NON-regenerative
RBC indices can be used to help classify anemia as _____, _____, or ______
Macrocytic, microcytic, or normocytic
What is normocytic anemia associated with?
variety of acute and chronic disorders
What is macrocytic anemia associated with?
usually REGENERATIVE anemia
What is microcytic anemia associated with?
almost always caused by IRON deficiency (usually 2’ to chronic blood loss)
Hemolytic anemia is caused by what?
Is it usually regen or non-regen?
destruction of RBCs within the blood
usually REGENERATIVE
RBC parasites, leptospira, FELV, blood transfusion incompatibility, toxins, etc are common causes of _____ anemia
Hemolytic
What is hemorrhagic anemia caused by?
acute or chronic blood loss
trauma, parasites, neoplasia, cystitis, GI ulceration, and coagulopathy are common causes of ______ anemia
hemorrhagic
Iron deficiency anemia is caused by?
iron deficient diet
chronic blood loss
Reduced rates of or defective erythropoiesis can result in normocytic anemia. True or False?
True
CKD, hypothyroidism, hypoadrenocorticism, bracken fern poisoning, iron/copper deficiency, parvo, and lead toxicity result in reduced/defective erythropoiesis. True or False?
True
