4NEMIAS COMPLICATING MALIGNANT NEOPLASMS may be seekt ondary to blood loss, increased blood destruction, invasion of the hemopoietic organs or represent a side effect of the myelo-depressive agents used in the treatment of the neoplasm. Often none of these etiologic factors can be demonstrated. The anemia is usually mild to moderate in severity (8 to 10 Gm. per cent ) and, less frequently, severe ( 7 Gm. per cent or less ) . The reticulocyte count is usually within normal limits. The red blood cells are normocytic. Mild to moderate degree of hypochromia of the red blood cells, not uniformly present, is often found upon examination of the peripheral blood smear. The bone marrow examination reveals normal cellularity with adequate erythroid activity. Erythrokinetic studies including radioiron clearance, red cell radioiron utilization, intestinal absorpton of iron and Cr51-tagged red blood cells survival14’23 often do not help in clarifying the mechanism of the anemia which remains obscure. Since the serum iron level is usually low despite increased iron stores5 and the anemia is not corrected by administration of iron orally, it was thought likely that a study of the degree and mode of reutilization of the iron already available in the body might be helpful in understanding the mechanism of the anemia. Freireich et al.6 has found poor reutilization of iron in dogs subjected to turpentine-induced inflammation. This paper reports the results of the attempts at such a study in patients with malignant diseases, and the implications of the findings.

Anemia of chronic disease.

I enjoyed reading the review article on anemia of chronic disease (ACD) that appeared in the October I , 1992 issue of Blood.’ I agree that the name of this type of anemia is a misnomer and misleading. I prefer to call it “anemia of defective iron reutilization.” Iron utilization is the iron that appears in red blood cells (RBC) after intravenous (IV) injection of radioactive inorganic iron int...

Iron deficiency-induced secretion of phenolics facilitates the reutilization of root apoplastic iron in red clover.

Phenolic compounds are frequently reported to be the main components of root exudates in response to iron (Fe) deficiency in Strategy I plants, but relatively little is known about their function. Here, we show that removal of secreted phenolics from the root-bathing solution almost completely inhibited the reutilization of apoplastic Fe in roots of red clover (Trifolium pratense). This resulte...

Hemolysis and Erythropoiesis . VI . A Comparative

O UR PREVIOUS OBSERVATIONS have shown that intraperitoneal administration of autohemolysates accelerates the recovery from anemia in bled dogs.13 On the basis of this and other experimental data4#{176} we reconsidered the hypothesis7’8 that red cell constituents have an erythropoietic stimulatory effect.1’6 However, it has been suggested that the above findings are due, instead, to the availabi...

Primary duodenal malignant melanoma: A case report

Background: Melanoma is a neoplasm derived commonly from melanocytic cells of skin. Although coetaneous presentation of malignant melanoma is easily recognizable, the presentation of melanoma in other organs is so confusing. In particular, when it metastasizes to other organs, many bizarre figures and unusual organs may be involved. In this report, we present a case of primary duodenal malignan...

Prevalence of Gastrointestinal Tract Lesions in Patients with Iron-Deficiency Anemia

Background: the Iron deficiency anemia (IDA) is a common cause of referral to medical departments. Chronic gastrointestinal (GI) blood loss is important cause of IDA and also an alarming sign of serious underlying disease. The information concerning ideal evaluation of the gastrointestinal tract in patients with the IDA is scant. We designed a prospective study to determine the frequency of GI ...
