Disturbances in iron metabolism can be genetic or acquired and accordingly manifest as primary or secondary iron overload state. Organ damage may result from iron overload and manifest clinically as cirrhosis, diabetes mellitus, arthritis, endocrine abnormalities and cardiomyopathy. Hemochromatosis inherited as an autosomal recessive disorder is the most common genetic iron overload disorder. E...

The secondary back-iron plays important role in performance of single-sided linear induction motors (SLIMs). On one hand, it provides a return path for the primary flux; on the other hand, it is employed as a mechanical support for the secondary sheet. The conductivity of the iron used in the back-iron as well as its magnetic permeability influence the outputs of the machine, while the magnetic...

Background Although chronic obstructive pulmonary disease is a known cause of secondary polycythemia with elevated erythropoietic demands in response to hypoxemia, anemia is relatively common in patients with chronic obstructive pulmonary disease and is related to increased mortality. However, little is currently known about the relationship between various iron parameters and disease severity ...

trichuriasis is an intestinal parasitic disease which is caused by trichuris trichiura, a soil transmitted helminth. in order to evaluate the iron status of trichuriasis in patients a total of 120 (49 males and 71 females) cases with trichuris trichiura as well as 54 healthy individuals were evaluated. blood samples were analyzed for serum iron, transferrin saturation percent, haemoglobin and o...

Iron participates in oxygen transport, energetic, metabolic, and immunologic processes. There are 2 main causes of iron overload: hereditary hemochromatosis which is a primary cause, is a metabolic disorder caused by mutations of genes that control iron metabolism and secondary hemochromatosis caused by multitransfusions, chronic hemolysis, and intake of iron rich food. The most common type of ...

BACKGROUND Patients with non-dialysis-dependent chronic kidney disease (ND-CKD) often receive an erythropoiesis-stimulating agent (ESA) and oral iron treatment. This study evaluated whether a switch from oral iron to intravenous ferric carboxymaltose can reduce ESA requirements and improve iron status and hemoglobin in patients with ND-CKD. METHODS This prospective, single arm and single-cent...

INTRODUCTION Iron parameters like serum ferritin and iron saturation are routinely used in diagnosing iron deficiency. However, these tests are influenced by many factors. We aimed to review the accuracy of iron parameters among inpatients in an acute care hospital. MATERIALS AND METHODS From October 1997 to April 2002, bone marrow aspirate samples from patients on whom concurrent iron studie...

Introduction: secondary hyperparathyroidism is listed among the possible reasons for intensifying the anemia and resistance to erythropoietin therapy in hemodialysis patients. Although its exact mechanism is not entirely clarified, but shift of bone marrow cells to adipocytes, bone marrow fibrosis and decreased calciteriol can be the causes. However, the role of secondary hyperparathyroidism in...
