Pernicious anemia is one form of vitamin B-12 deficiency that results from the autoimmune process described above. However, other causes of vitamin B-12 deficiency can also produce the same signs and symptoms as pernicious anemia.s discussed previously, true pernicious anemia results from an autoimmune condition that impairs absorption of dietary vitamin B-12, resulting in vitamin B-12 deficiency. Vitamin B-12 deficiency of any cause will result in anemia and neurologic symptoms.
A number of unrelated symptoms can occur in vitamin B12 deficiency. Clinical manifestations of vitamin B12 deficiency include: Hematological changes, such as megaloblastic anemia (characterized by large red blood cells), and a low production of other blood cell types, which is known as pancytopenia. Types of pancytopenia seen in vitamin B12 deficiency include leucopenia (low white blood cell levels), thrombocytopenia (low platelet count), and anemia.
