Cellular Regulation:
Cellular regulation is the coordinated function of the physiological controls within the body to maintain homeostasis from changes to internal and external environment.
Anemias
Inadequate oxygenation delivery to body cells due to lack of RBCs or a dysfunction of RBCs within the blood
Acquired Aplastic
- Bone marrow fails to produce blood cells (RBCs, WBCs, and platelets)
- Destruction of red bone marrow due to significant tx (radiation, chemotherapy, and infection)
- Amount of stem cells in bone marrow are significantly reduced
- Onset is sudden
Hemolytic
- Destruction of RBCs faster then they are created
Intrinsice factors
- Cell membrane defects
- Defects in hemoglobin structure and function
Extrinsic factors
- Exposure to drugs, chemicals, venom, bacteria, or trauma
Sickle Cell
- Genetic disorder causing distortion of the RBC shape
- Abnormal hemoglobin S
- Autosomal recessive disease
- RBCs become curved (sickle shaped), stiff, and sticky
- Shape results in weak structure resulting in a deminished lifespan
Glucose-6-phosphate dehydrogenase (G6PD)
- Genetic/hereditary disorder that is incapable of RBC metabolism
- G6PD is an enzyme that helps protect RBCs from damage and premature destruction
- Hemoglobin is directly oxygenated resulting in damage
- Impairs compensatory increases of glucose metabolism resulting in damage
- Triggered by stressors
Thalassemia
Genetic/inherited disorder of hemoglobin synthesis
- Missing Alpha or Beta hemoglobin molecular chains
- Deficient hemoglobin production
- unable to carry sufficient oxygen
- RBCs produced are microcytic, hypochromic, and fragile
Acquired Hemolytic
Hemolysis from factors outside the RBCs
- Trauma to RBCs from:
- Prosthetic heart valves
- Severe burns
- Hemodialysis
- Radiation
- Autoimmune disorders
- Infections
- Transfusion reactions
- Exposure to drugs, chemicals, venom, bacteria, or trauma
Nutritional
- Absorption complications
- Gastrectomy
- Chronic diarrhea
- Malsabsorption syndromes
- Occur from conditions or dietary insufficiencies
- Vegetarian diets
- inadequate protien
- Increased Metabolic requirements
Iron Deficiency (Hypochromic)
- Low hemoglobin caused by iron deficiency
- Iron binds with protoporphyrin IX
- Causes can be from low iron diets (vegetarians) and heavy menstruation
- Most common type of anemia
- Results from
- Poor intake (vegetarian diet)
- Increased demand (pregnancy)
- Absorption issue
- Celiac disease
- Gastric bypass
Pernicious (B12)
- Failure of stomach to absorb B12 due to lack of intrinsic factor or irreversible malabsorption syndrome
- Intrinsic factor affects how the GI system absorbs B12
- B12 is required to produce healthy RBC's
- Autoimmune response that destroys parietal cells
- Megaloblastic anemia
- Onset is gradual
- Difficulty maintaining balance
- Impairs cell division and advancement of a cell nucleus
Folic Acid
- Lacks the folic acid in the blood, due to the inability of the liver to store & metabolize folates
- Malabsorption Disorders
- Chronically undernourished patients
- Alcoholics
- Patients on TPN
- Pregnancy
-Certain medications (methotrexate)
- Chemotherapeutic medications
- Onset is gradual
Blood loss
- Acute or chronic loss of RBCs through active bleeding
- Triggers compensatory mechanisms
- increased heart rate
- peripheral vessel constriction
- Continued blood loss depletes iron stores
- Normocytic anemia
- can become microcytic in chronic cases
Medical
- Occurs due to underlying medical condition creating acute or chronic bleeding within the body.
- GI hemorrhage
- heavy or prolonged menstrual bleeding
Trauma
- Due to significant trauma (blunt or penetrating) sustained by the patient
- Significant trauma: loss of limb, internal hemorrhage due to blunt/penetrating trauma, intercranial hemorrhage
