Fe deficiency and Fe-deficiency anaemia are common in patients with inflammatory bowel disease (IBD). Traditional clinical markers of Fe status can be skewed in the presence of inflammation, meaning that a patient's Fe status can be misinterpreted. Additionally, Fe absorption is known to be down-regulated in patients with active IBD. ...

Iron deficiency anaemia (IDA) is the most common form of anaemia worldwide. In men and postmenopausal women the commonest cause of IDA is blood loss from lesions in the gastrointestinal tract, making it a common cause of referral to gastroenterologists. Causes of IDA relate either to blood loss or iron ...

INTRODUCTION: Atherosclerosis (AS) and malnutrition are 2 major causes of morbidity and mortality in hemodialysis (HD) patients. A high body fat percentage (BFP) may be paradoxically associated with improved survival in chronic HD patients. We aimed to establish BFP profile of the HD patients by using bioimpedance analysis, body mass ...

Hepcidin has been established as a central regulator of iron metabolism. In most patients with chronic kidney disease (CKD), serum hepcidin levels are relatively high, favoring iron sequestration in several cell types and organs and thereby leading to iron-related complications. In the absence of overt inflammation, serum hepcidin has been ...

BACKGROUND: HFE hemochromatosis (HFE-H) is the most common and well-defined inherited cause for iron-related morbidity and mortality. Majority of patients with HFE-H are homozygote for C282Y mutation. Recent studies suggest that iron accumulation in most types of hemochromatosis is due to deficiency of hepcidin, a central iron regulator. However, the ...

Background: Sickle cell disease is an autosomal, recessive hemoglobinopathy characterized by hemolytic anemia. Red blood cell transfusions are uncommon therapeutic mainstay in sickle cell disease and repeated transfusions can result in iron overload. The predicted risks of iron overload and organ failure increase with both the duration of disease requiring ...

Studies have shown that red cell distribution width (RDW) is related to outcome in chronic heart failure (CHF). The pathophysiological process is unknown. We studied the relationship between RDW and erythropoietin (EPO) resistance, and related factors such as erythropoietic activity, functional iron availability and hepcidin. In the Mechanisms of Erythropoietin ...
