Characteristics of vitamin B12 deficiency in patients with plasma cell disorders

Vitamin B12 deficiency is prevalent among patients with plasma cell dyscrasias (PCDs) but the association is poorly understood. Among 501 patients with PCDs, 20% had low B12. Low B12 was more prevalent in patients with preserved renal function. MCV was not clinically different between low and normal B12 patients and may not be reliable in PCDs.
