Bone marrow examination may be required if myelodysplasia is a consideration or the etiology cannot be determined following the above-mentioned investigations. Types of Macrocytic Anemia. Type II is also termed HEMPAS (hereditary erythroblastic multinuclearity with a positive acidified serum test), which differs from PNH by a negative sucrose hemolysis test result. Many cases can be treated with supplements and diet changes to increase your iron intake. RBCs: Elevated MCH and mean cell volume (often 106 fl or more), with normal MCHC; marked variability in cell size (anisocytosis) and shape (poikilocytosis), Neutrophils: Hypersegmentation (>5% of neutrophils with five lobes or a single neutrophil with six lobes), Platelets: Usually normal; thrombocytopenia in more severe anemia, May occur in vegetarians who consume no animal products, Seen in exclusively breastfed infants of vitamin B12–deficient mothers, Ileal mucosal abnormalities (e.g., Crohn disease), Competition for cobalamin in bacterial overgrowth syndromes or infection with the fish tapeworm Diphyllobothrium latum, Congenital abnormalities of the receptor for vitamin B12–intrinsic factor complex, Gastric mucosal defects that interfere with the secretion of intrinsic factor.
