Study Notes
Anemia
Iron Deficiency Anemia
- Most common type of anemia worldwide
- Caused by inadequate iron intake, poor absorption, or chronic blood loss
- Iron is essential for hemoglobin production
- Symptoms:
- Fatigue
- Weakness
- Pale skin
- Shortness of breath
- Headaches
- Diagnosis:
- Low hemoglobin and hematocrit levels
- Low serum ferritin levels
- Microcytic, hypochromic red blood cells
- Treatment:
- Iron supplements
- Dietary changes to increase iron intake
- Addressing underlying causes of blood loss or poor absorption
Vitamin Deficiency Anemia
- Caused by deficiencies in vitamins essential for red blood cell production
- Types:
- Vitamin B12 deficiency anemia
- Folate deficiency anemia
- Symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Pale skin
- Numbness or tingling in hands and feet
- Diagnosis:
- Low hemoglobin and hematocrit levels
- Abnormal red blood cell morphology
- Low serum vitamin levels
- Treatment:
- Vitamin supplements
- Dietary changes to increase vitamin intake
- Addressing underlying causes of deficiency
Anemia of Chronic Disease
- Caused by chronic inflammation or infection
- Red blood cell production is impaired due to:
- Inflammation-mediated cytokine production
- Iron sequestration
- Symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Pale skin
- Underlying chronic disease symptoms
- Diagnosis:
- Low hemoglobin and hematocrit levels
- Elevated inflammatory markers
- Normal or elevated serum iron levels
- Treatment:
- Addressing underlying chronic disease
- Anti-inflammatory medications
- Iron supplements if necessary
Anemia of Inflammation
- Similar to anemia of chronic disease, but with a focus on inflammation
- Caused by:
- Chronic inflammation
- Inflammatory cytokine production
- Iron sequestration
- Symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Pale skin
- Underlying inflammation symptoms
- Diagnosis:
- Low hemoglobin and hematocrit levels
- Elevated inflammatory markers
- Normal or elevated serum iron levels
- Treatment:
- Addressing underlying inflammation
- Anti-inflammatory medications
- Iron supplements if necessary
Haemolytic Anemia
- Caused by premature destruction of red blood cells
- Types:
- Autoimmune hemolytic anemia
- Inherited hemolytic anemia (e.g., sickle cell disease, thalassemia)
- Acquired hemolytic anemia (e.g., drug-induced, infection-related)
- Symptoms:
- Fatigue
- Weakness
- Shortness of breath
- Pale skin
- Jaundice
- Diagnosis:
- Low hemoglobin and hematocrit levels
- Elevated bilirubin levels
- Abnormal red blood cell morphology
- Treatment:
- Addressing underlying cause
- Blood transfusions
- Corticosteroids or immunosuppressive therapy for autoimmune cases
Iron Deficiency Anemia
- Most common type of anemia worldwide
- Caused by inadequate iron intake, poor absorption, or chronic blood loss
- Iron is essential for hemoglobin production
- Symptoms: fatigue, weakness, pale skin, shortness of breath, headaches
- Diagnosis: low hemoglobin and hematocrit levels, low serum ferritin levels, microcytic, hypochromic red blood cells
- Treatment: iron supplements, dietary changes to increase iron intake, addressing underlying causes of blood loss or poor absorption
Vitamin Deficiency Anemia
- Caused by deficiencies in vitamins essential for red blood cell production
- Types: vitamin B12 deficiency anemia, folate deficiency anemia
- Symptoms: fatigue, weakness, shortness of breath, pale skin, numbness or tingling in hands and feet
- Diagnosis: low hemoglobin and hematocrit levels, abnormal red blood cell morphology, low serum vitamin levels
- Treatment: vitamin supplements, dietary changes to increase vitamin intake, addressing underlying causes of deficiency
Anemia of Chronic Disease
- Caused by chronic inflammation or infection
- Red blood cell production is impaired due to inflammation-mediated cytokine production and iron sequestration
- Symptoms: fatigue, weakness, shortness of breath, pale skin, underlying chronic disease symptoms
- Diagnosis: low hemoglobin and hematocrit levels, elevated inflammatory markers, normal or elevated serum iron levels
- Treatment: addressing underlying chronic disease, anti-inflammatory medications, iron supplements if necessary
Anemia of Inflammation
- Similar to anemia of chronic disease, but with a focus on inflammation
- Caused by chronic inflammation and inflammatory cytokine production, iron sequestration
- Symptoms: fatigue, weakness, shortness of breath, pale skin, underlying inflammation symptoms
- Diagnosis: low hemoglobin and hematocrit levels, elevated inflammatory markers, normal or elevated serum iron levels
- Treatment: addressing underlying inflammation, anti-inflammatory medications, iron supplements if necessary
Haemolytic Anemia
- Caused by premature destruction of red blood cells
- Types: autoimmune hemolytic anemia, inherited hemolytic anemia (e.g., sickle cell disease, thalassemia), acquired hemolytic anemia (e.g., drug-induced, infection-related)
- Symptoms: fatigue, weakness, shortness of breath, pale skin, jaundice
- Diagnosis: low hemoglobin and hematocrit levels, elevated bilirubin levels, abnormal red blood cell morphology
- Treatment: addressing underlying cause, blood transfusions, corticosteroids or immunosuppressive therapy for autoimmune cases
