Anemia Of CD Flashcards
If an anemia occured in response to systemic illness or inflammation it’s called?
ACD
What’s the pathophysiology of ACD
• lightly shortened RBC survival, thought to be due to release of inflammatory cytokines, occurs in patients with cancer or chronic granulomatous infections
• Erythropoiesis is impaired because of decreases in botherythropoietin(EPO) production and marrow responsiveness to EPO.
• Iron metabolism is altered due to an increase in hepcidin, which inhibits iron absorption and recycling, leading to iron sequestration
What’s the typical Morphology of ACD
- normochromic or mildly hypo occurs in patients w systemic disease
- reduced serum iron and iron-binding capacity, and normal or raised serum ferritin with adequate iron stores
Etiology of ACD, give example to each
- Chronic and acute viral, bacterial, parasitic or fungal infections
- Systemic connective tissue diseases, vasculitis and autoimmune disorders (rheumatoid arthritis, systemic lupus, IBD)
- chronic diseses (CKD,DM)
- alignancy
How to diagnose Anemia of chronic disease
• Symptoms of the underlying disease
• Symptoms of the anemia
• The anemia is usually mild or moderate ( Hb 8-11g/dl) - lower values are observed in 20-30% of patients • The anemia is most often normochromic and normocytic, microcytic later on
• Erythrocyte sedimentation rate (ESR) - usually raised
Whn orsein a lab for a patient with anemia caused by Cd what would u expect to find?
- Serum Iron - decreased
- TIBC Reduced
- Transferrin saturation reduced
Serum Ferritin-increased or normal - Serum Transferrin Receptor (sTR)-Normal
- Sideroblasts in the bone marrow-reduced (5-20%)
