In contrast, the characteristics of anemia that may occur with deficiencies of other micronutrients, such as some of the other vitamins and minerals, are poorly defined and relatively rare in humans. When present, they usually exist not as isolated deficiencies of one vitamin or one mineral but rather as a combination of deficiencies resulting from malnutrition or malabsorption. In this context, it is difficult to deduce which abnormalities are a result of which deficiency. Studies in experimental animals may not accurately reflect the role of micronutrients in humans. Accordingly, our knowledge of the effect of many micronutrients on hematopoiesis is fragmentary and based on clinical observations and interpretations that may be flawed. Inborn metabolic errors that affect single micronutrient pathways may shed light on the specific effects of those micronutrients on hematopoiesis. The levels normally found in the serum, red cell, and leukocytes are shown in Table 45–1.
