BACKGROUND Increased levels of hepcidin, the master regulator of iron homeostasis, contribute to the diversion of iron underlying the anemia of chronic disease. Yet hepcidin levels are low in anemia of chronic disease with concomitant true iron deficiency. Here we clarify the different underlying pathways regulating hepcidin expression under these conditions in vivo. DESIGN AND METHODS We use...

Celiac disease is an autoimmune disorder that occurs in genetically predisposed individuals as the result of an immune response to gluten. It is present in approximately 1% of the population. Diarrhea has become a less common mode of presentation (<50% of cases) than it once was. Other presentations include iron-deficiency anemia, osteoporosis, dermatitis herpetiforme, and neurologic disorders,...

iron deficiency is one of the most common nutritional problems in the world, it is frequently found in both developed and developing countries and mainly affects women of childbearing age. the aim of this study was to investigate the relationship of iron deficiency anemia in pregnant women on neonatal weight. the study subjects were a group of 241 women aged between 20 and 34 years who were div...

The activity of nitric oxide synthase (NOS) was assayed in enterocytes isolated from human duodenal biopsies to determine its role in celiac disease. Patients were categorized into groups with irritable bowel syndrome, iron-deficiency anemia, B(12)/folate deficiency, and treated and untreated celiac disease. Enterocytes isolated from all groups showed 1400W-inhibitable Ca2+-independent NOS acti...

Celiac disease is an autoimmune disorder of the gastrointestinal tract. It is triggered by exposure to dietary gluten in genetically susceptible individuals. Gluten is a storage protein in wheat, rye, and barley, which are staples in many American diets. Celiac disease is characterized by chronic inflammation of the small intestinal mucosa, which leads to atrophy of the small intestinal villi a...

INTRODUCTION refractory iron-deficiency anemia has a multifactorial origin related to various gastrointestinal conditions, with celiac disease plus malabsorption and IBD together with isolated gluten intolerance being most common. OBJECTIVES to determine the prevalence of serum, genetic, and histological markers for gluten intolerance, and to analyze the response to gluten withdrawal from the...

Background. Iron-deficiency anemia is described to be a common problem in patients with inflammatory bowel disease (IBD), which is frequently associated with a reduced quality of life. Therefore, the aim of this study is to assess the prevalence of iron deficiency anemia in a population-based cohort at time of first diagnosis and during the early course of the disease. Methods. As far as availa...

Background & Aims: The activity of nitric oxide synthase was assayed in enterocytes isolated from human duodenal biopsies to determine its role in celiac disease. Patients were categorized into those with irritable bowel syndrome, iron deficiency anemia, B12/folate deficiency and treated and untreated celiac disease. Methods & Results: Enterocytes isolated from all groups showed 1400W-inhibitab...

ampullary tumor is a rare cancer. these patients most commonly present with obstructive jaundice but sometimes disease appear with uncommon signs. this report is an example of such cases. our case is a 53 year old man who presented with recurrent fever and chills and iron deficiency anemia and has been misdiagnosed for two years. the proper diagnosis occurred when the patient showed abnormal li...
