EXAM 4- Immunostimulant drugs Flashcards
Infection is likely to occur when a patient is -
neutropenic
action of colony stimulating factor (CSF)
act on the hematopoietic cells to stimulate proliferation, differentiation and maturation of WBC’s
uses of Colony Stimulating Factor
- to treat or prevent infection (minimizing neutropenia) associated with:
- Chemotherapy-induced neutropenia during solid tumor cancer treatment
- During bone marrow transplant (BMT)
- Production of stem cells for harvest before bone marrow transplant
- Neutropenia in those susceptible to symptomatic chronic infection
example of Colony Stimulating Factor
filgrastim- used before stem cell donation to increase stem cell production
adverse reactions of Colony Stimulating Factor
- Bone pain
- Hypertension
- Nausea/vomiting
- Alopecia
- Hypersensitivity
the process of making platelets
thrombopoiesis
drug used to stimulate thrombopoiesis
Oprelvekin
use of Oprelvekin
to treat or prevent thrombocytopenia with chemotherapy
adverse reactions of Oprelvekin
- dyspnea due to fluid retention
- syncope (fainting)
- tachycardia, palpitations or atrial fibrillation
- stroke
causes of anemia
decrease in the number of RBC’s
decrease in the amount of hemoglobin in the RBC’s
Both
characterized by an inadequate amount of iron in the body to produce hemoglobin
Iron deficiency
resulting from lack of secretion by the gastric mucosa of the intrinsic factor essential to the formation of RBC’s and the absorption of vitamin B12
Pernicious anemia
actions of Erythropoiesis-stimulating agents (ESA)
stimulate erythropoiesis (making RBC’s)
examples of Erythropoiesis-stimulating agents (ESA)
- epoetin alfa (Epogen)
- darbepoetin alfa (Aranesp)
uses of Erythropoiesis-stimulating agents (ESA)
- chronic renal failure
- chemotherapy
- AZT therapy for HIV infection
- postsurgical blood replacement in place of allogeneic transfusions
- Increase or maintain RBC levels and decrease need for blood transfusion
