Study Notes

Anemia and White Blood Cells Overview

Anemia clinical signs include fatigue, skin pallor, weakness, and increased heart and respiratory rates
Types of anemia include hemorrhagic, aplastic, pernicious, folate deficiency, iron deficiency, hemolytic, sickle cell, and thalassemia
Pernicious anemia is caused by vitamin B12 deficiency, leading to decreased RBC, WBC, and platelet numbers
Folate deficiency anemia is caused by a lack of folate (vitamin B9) and is common in alcoholism and malnutrition
Iron deficiency anemia results from inadequate iron supply for hemoglobin synthesis, leading to microcytic and hypochromic RBCs
Hemolytic anemias are caused by decreased RBC lifespan or increased RBC destruction, leading to symptoms like jaundice and spleen swelling
Sickle cell anemia is a genetic disease leading to abnormal hemoglobin formation, primarily found in African-Americans
Thalassemia is a group of inherited hemolytic anemias occurring mainly in people of Mediterranean descent
Thalassemia symptoms include anemia, skeletal deformities, and spleen and liver swelling, requiring marrow and stem cell transplantation for treatment
Hemolytic disease of newborn and erythroblastosis fetalis are caused by blood incompatibility between the mother and developing baby during pregnancy
WBCs are categorized as granulocytes or agranulocytes, with normal counts ranging from 5000 to 10,000/mm3 of blood
Leukocytosis is an abnormally high WBC count, often found in bacterial infections and blood cancers like leukemia
