CONCLUSIONS: Macrocytic anemia is not the only hematological presentation of ABG. [ncbi.nlm.nih.gov]

Children ≤10y presented a lower prevalence (p 65y, 60.2%). II. The overall subsample presented 24.7% low B-12, 8.1% low folate, 22.2% anemia and 3.7% macrocytosis, 1.3% macrocytic anemia. [b12-institute.nl]

Howell-Jolly bodies (residual fragments of the nucleus) are usually present. If iron deficiency or impaired iron utilization is present simultaneously, macrocytosis may not develop. [merckmanuals.com]

• Splenectomy

  Because RBC membrane molding occurs in the spleen after cell release from the marrow, RBCs may be slightly macrocytic after splenectomy, although these changes are not associated with anemia. [merckmanuals.com]

  Splenectomy may cause macrocytosis because cells are not processed as thoroughly when the spleen is absent. [aafp.org]

  Sickling can lead to a range of severe symptoms: Vaso-occlusion leading to tissue infarction (for example, dactylitis – swollen hands due to vaso-occlusion of hand bones) Auto-splenectomy occurs if spleen gets infarcted; this increases chances of acquiring [lecturio.com]

• Anorexia

  Gastrointestinal manifestations are common, including diarrhea, glossitis, and anorexia. Neurologic manifestations, including peripheral neuropathy and gait instability, are unique to B12 deficiency and can be permanent if prolonged. [merckmanuals.com]

  However, young women who eat low carbohydrate diets, as well as socially isolated individuals, or those with chronic intestinal disease (tropical sprue) with anorexia may continue to be at risk for folate deficiency. [cancertherapyadvisor.com]

  Patients with vitamin B 12 deficiency may describe paresthesias related to peripheral neuropathy, poor or strict vegan diet, lack of socioeconomic resources, bowel-related symptoms (including diarrhea), or a history of bowel surgery for weight loss. [aafp.org]

• Neurologic Manifestation

• Howell-Jolly Bodies

  Howell-Jolly bodies are DNA remnants seen with a macrocytic anemia or a damaged spleen. You will find them in B12 deficiency anemia, folate devicenet anemia, sickle cell anemia and celiac disease. [physicianassistantexamreview.com]

  Although iron deficiency can mask macrocytosis, Howell-Jolly bodies and granulocyte hypersegmentation should still be present. Serum B12 and folate levels should be measured. [merckmanuals.com]

Nine cases (36%) showed macrocytic anemia without any evident etiologies during therapy. The cumulative appearance rate of anemia was 19% at 12 weeks and 51% at 18 weeks. [ncbi.nlm.nih.gov]

The common theme of etiologies that give rise to macrocytic anemias are their capacity to interfere with DNA Synthesis. This results in ineffective erythropoiesis within the bone marrow and over time, anemia. [pathwaymedicine.org]

Megaloblastic anemia is characterized by macro-ovalocytes, in contrast to the round macrocytes usually found in macrocytosis of nonmegaloblastic etiology [1]. [path.upmc.edu]
