1711. All are true regarding Anaemia of Chronic Diseases, except –
First, the core concept here is Anemia of Chronic Disease (ACD), also known as anemia of inflammation. It's a common type of anemia associated with chronic infections, inflammatory diseases, or malignancies. The key points are that it's a normocytic, normochromic anemia, and it's characterized by increased iron in macrophages but decreased serum iron due to hepcidin upregulation.
Now, the question asks which statement is NOT true about ACD. Let's think about the typical features. ACD is usually associated with low serum iron, high ferritin (due to inflammation), and low transferrin saturation. The bone marrow shows iron storage because the iron isn't being released properly due to hepcidin. Also, erythropoietin levels might be normal or elevated, but the response is blunted.
The options are A, B, C, D, but the user didn't provide them. However, common distractors in ACD questions include things like microcytic anemia (which is incorrect because ACD is normocytic), low ferritin (incorrect because ferritin is elevated in inflammation), microcytic anemia (another distractor), or maybe incorrect treatment approaches like iron supplementation without checking for hepcidin levels.
Assuming the options are standard, the incorrect statement (the exception) might be something like "Treatment involves oral iron supplementation." Since ACD is due to hepcidin blocking iron release, giving oral iron isn't effective unless hepcidin levels are low. So if an option states that oral iron is the treatment, that's the exception.
Another possible incorrect option could be "Low serum ferritin" because in ACD, ferritin is elevated due to inflammation, not iron stores. So if an option says serum ferritin is low, that's wrong.
So the correct answer would be the one that states something that's not true about ACD. For example, if option C says "Microcytic anemia," that's incorrect because ACD is normocytic. Alternatively, if an option claims that iron deficiency is the cause, that's wrong because ACD is due to iron sequestration, not deficiency.
The clinical pearl here is remembering that ACD is a normocytic anemia with high ferritin and low serum iron. Also, treatment isn't just giving iron; it's addressing the underlying chronic condition. So the key is to distinguish ACD from iron deficiency anemia, which is microcytic with low ferritin.
Putting this together, the correct answer is the option that incorrectly attributes a feature to ACD, like being microcytic or having low ferritin. The explanation should clarify why each incorrect option is wrong and highlight the key differences between ACD and other anemias.
**Core Concept**
Anemia of Chronic Disease (ACD) is characterized by normocytic, normochromic anemia due to inflammation-driven dysregulation of iron metabolism. Key features include elevated serum ferritin, low transferrin saturation, and impaired iron release from macrophages via hepcidin overexpression.
**Why the Correct Answer is Right**
The correct option would
