Study Notes

Cytotoxic viral infections can cause anemia, cancer, and other clinical features.
Lowered Red Blood Cell (RBC) count results in breathlessness and fatigue.
Lowered White Blood Cell (WBC) count increases risk of infections.
Lowered Platelet count increases risk of bleeding.
Erythropoiesis stimulating agents (ESAs) are used to treat anemia caused by various conditions, including end-stage renal disease, chemotherapy, and HIV.
ESAs include Epoetin Alfa (Epogen), which is a biosynthetic form of the natural hormone erythropoietin, and longer-acting form known as darbepoetin.
ESAs have contraindications, such as drug allergies, uncontrolled hypertension, head and neck cancer, and risk of thrombosis.
Iron is essential for erythropoiesis and is administered to alleviate symptoms of iron deficiency anemia, but the underlying cause of the anemia should be treated.
Iron is available as oral and injectable preparations, and common side effects include GI disorders, staining of teeth, pain upon injection, and iron toxicity.
Folic acid is a water-soluble B complex vitamin that is essential for erythropoiesis and is used to treat folic acid deficiency, during pregnancy to prevent neural tube defects, and in malabsorption syndromes.
Cyanocobalamin (Vitamin B12) is used to treat pernicious anemia and other megaloblastic anemias and is typically given by deep intramuscular injection.
Leukemia is a malignant disease that arises from bone marrow stem cells and is more common in males and females.
Risk factors for leukemia include chromosomal abnormalities, chemotherapy, ionizing radiation, and chemical agents.
Epidemiology of leukemia includes an increased incidence in older adults and a higher incidence in males compared to females.
The American Cancer Society estimates that there will be approximately 60,000 new cases of leukemia and 24,000 deaths from the disease in the US in 2021.
Acute leukemia (ALL) and chronic leukemia (CLL) are the two main types of leukemia.
ALL is characterized by the rapid production of abnormal white blood cells, which can crowd out healthy cells and disrupt normal blood function.
CLL is characterized by the slow production of abnormal white blood cells, which gradually accumulate over time and can lead to a variety of complications.
Treatment for leukemia includes chemotherapy, radiation therapy, bone marrow transplant, and targeted therapy.
Prognosis for leukemia depends on the type and stage of the disease, age and overall health of the patient, and response to treatment.
