3. Secondary anemia: causes, pathogenesis, clinical and biochemical signs, diagnosis, treatment. Flashcards
1
Q
how can we diffrentuate anemia of acute and chronic inflammtion from mild to moderate iron deficiny anemia
A
inflamtion serum iron = low total iron binding capacity / inderct trasferrin = normal or low transferrin saturation =low serum ferritin = normal or high plasma transferrin receptor = high
anemia of chronic disease mostly normchormic and normocytic (only 30 percent hypochromic and microcytic)
mild aniso and poikilocytosis
normal reticulocyte count
iron def serum iron = low TIBC = high transferrin stauration = low serum ferritin = low plasma transferrin receptor - increased
reticulocyte count = low for anemia
2
Q
what are the chronic diseases which can cause iron def microcytic anemia ?
A
rheumatic arthritis, SLE , ulcerative collitis , chrons disease polyartheritis nodosa
malignancy
tuberculosis
3
Q
what is the pathogenesis of anemia in chronic disease ?
A
impairment of iron utilisation
inhibitor or erythropoesisi
blunted response to erytroportin
reduced RBC survival
iron sequestration and microbicidal strategy
