Pancytopenia (i.e., a decrease in all circulating hematologic cell lines) can result from peripheral destruction of cells or a primary insult to the bone marrow. Many infectious, immunemediated, and neoplastic conditions have been associated with pancytopenia in dogs and cats. Bone marrow aspirates and/or core biopsy samples are generally required to fully characterize the marrow disease, especially in cases of decreased hematopoietic cell production. Understanding the mechanisms by which various disorders alter circulating blood or marrow cells may aid in developing a diagnostic and/or treatment plan.The prognosis in pancytopenic patients is variable and depends on the underlying cause.

Iron is an essential element for nearly all living organisms and disruption of iron homeostasis can lead to a number of clinical manifestations. Iron is used in the formation of both hemoglobin and myoglobin, as well as numerous enzyme systems of the body. Disorders of iron in the body include iron deficiency anemia, anemia of inflammatory disease, and iron overload. This article reviews normal iron metabolism, disease syndromes of iron imbalance, diagnostic testing, and treatment of either iron deficiency or excess. Recent advances in diagnosing iron deficiency using reticulocyte indices are reviewed.
