OBJECTIVE: To study the therapeutic efficacy of an oral iron retard preparation in patients with iron deficiency anemia. METHODS: In an investigator-initiated open study, 28 patients with iron deficiency anemia were treated with an iron sulfate sustained-release preparation (80 mg iron ions per tablet). The bioavailability was determined from the increase in the haemoglobin value under therapy and the measured blood loss. For the quantification of individual blood losses, a (59)Fe labeling method was used and the (59)Fe whole body retention in the observation period was measured with a whole body counter...

Iron deficiency (ID) and iron deficiency anemia (IDA) are major contributors to infant and maternal morbidity worldwide. There is limited longitudinal data on iron status in young infants and on methods to adjust iron biomarkers for inflammation. We aimed to quantify the prevalence of inflammation-adjusted ID, anemia, and IDA over the first year in a cohort of Bolivian infants and their mothers. Healthy mother-infant dyads were recruited from two peri-urban hospitals. Infants provided three blood draws (2, 6-8, and 12-18 months; N = 160); mothers provided two blood draws (1 and 6-8 months postpartum [plus third anemia measurement at 12-18 months]; N = 250)...

BACKGROUND: Iron Deficiency Anemia (IDA) is an important health problem all around the world especially in developing countries. In the Mediterranean countries another prevelant reason of anemia is Thalassemia. Certain strategies had been established as a government policy to reduce prevalence in North Cyprus, such as pre-marital screening of Thalassemia. The prevalence of thalassemia trait has not been evaluated since then. The aim of this study was to detect the prevalence of IDA, thalassemia trait in infants under regular follow-up and to evaluate the compliance to prophylactic iron supplementation (PIS) and its effect on IDA...

Iron plays the central role in the oxygen transport by the erythrocyte as a constituent of heme and hemoglobin. The importance of iron and heme also resides in their regulatory roles during erythroblast maturation. The transcription factor Bach1 may be involved in their regulatory roles since it is inactivated by direct binding of heme. To address whether Bach1 is involved in the responses of erythroblasts to iron status, low iron conditions that induced severe iron deficiency in mice were established. Under iron deficiency, extensive gene expression changes and mitophagy disorder were induced during maturation of erythroblasts...

BACKGROUND: Iron deficiency (ID) is common in toddlers in developing countries. Iron fortified or meat-based complementary foods may be effective to prevent ID. OBJECTIVE: Our objective was to compare iron status at 18 months and growth from 6 to 18 months in rural poor toddlers fed 3 different complementary foods. METHODS: The study was nested within a larger trial in which 6-month-old infants were randomized to receive 50g/d meat (MG), an equi-caloric fortified cereal supplement (FG) or local cereal supplement (LG) for 1 year...

A protocol-driven, systematic pathway was developed to allow rapid and coordinated investigation of patients with iron-deficiency anemia (IDA) in a nurse-delivered outpatient setting. The study objective was to assess the safety and efficacy of the pathway by 5-year outcome data for the exclusion of gastrointestinal (GI) malignancy. This is a 5-year follow-up study of 122 patients entered onto the pathway with negative initial upper and lower GI investigations. The study was conducted at Hereford County Hospital NHS Trust (a district general hospital serving 220,00 people)...

OBJECTIVE: Preconception micronutrient interventions may be a promising approach to reduce anemia and iron deficiency during pregnancy, but currently we have limited data to inform policies. We evaluated whether providing additional pre-pregnancy weekly iron-folic acid (IFA) or multiple micronutrient (MM) supplements compared to only folic acid (FA) improves iron status and anemia during pregnancy and early postpartum. METHODS: We conducted a double blind randomized controlled trial in which 5011 Vietnamese women were provided with weekly supplements containing either only 2800 μg FA (control group), IFA (60 mg Fe and 2800 μg FA) or MM (15 micronutrients with similar amounts of IFA)...

Idiopathic pulmonary hemosiderosis is primarily a disorder of childhood, which is characterized by hemoptysis, iron deficiency anemia, and diffuse parenchymal infiltrates on chest x-ray secondary to recurrent attacks of alveolar hemorrhage. It can be diagnosed by showing hemosiderin laden macrophages in bronchoalveolar lavage fluid after other specific causes of diffuse alveolar hemorrhage are definitely excluded. A 5-year-old male patient was admitted to our clinic with sudden-onset pallor during iron therapy given for anemia...

BACKGROUND: Anal stricture is a disabling condition which is often unresponsive to conservative medical management. The complications of surgical procedures such as dilatations and anoplasty make it a formidable treatment challenge. Through this case, we report and explore a new medical treatment for ano-rectal strictures with an analogy to Plummer Vinson syndrome. A 69-year-old male presented with chronic constipation, rectal pain, and easy fatigability. The physical exam was negative for anal fissure and a digital rectal examination could not be completed because an index finger could not be advanced through the narrowed anus...

Adequate supply of micronutrients during the first 1000 days is essential for normal development and healthy life. We aimed to investigate if interventions administering dietary doses up to the recommended nutrient intake (RNI) of iron and zinc within the window from conception to age 2 years have the potential to influence nutritional status and development of children. To address this objective, a systematic review and meta-analysis of randomized and quasi-randomized fortification, biofortification, and supplementation trials in women (pregnant and lactating) and children (6-23 months) delivering iron or zinc in doses up to the recommended nutrient intake (RNI) levels was conducted...

Iron-deficiency anemia is the most common hematologic problem in the world. Although oral iron is often viewed as front-line therapy, extensive published evidence has accumulated that IV iron is superior, in both efficacy and safety, to oral iron in many clinical situations and should be introduced much sooner in the treatment paradigm of iron-deficient patients. In this chapter, we will review the formulations of IV iron that allow total complete replacement doses in 1 or 2 sessions including practical tips for administration...

REVIEW
Christian S Jackson, Richard Strong
Gastrointestinal angiodysplasia (GIAD) are red flat arborized lesions that are found throughout the entire gastrointestinal tract. GIAD can vary in size and have a range of presentation from occult to life-threatening bleeding. The typical presentation is intermittent bleeding in the setting of iron deficiency anemia. Endoscopy is the primary means of diagnosis and endoscopic therapy is noted to be initially effective. However, rebleeding can be as high as 40% to 50% in patients with small bowel GIAD. This review describes the pathophysiology for the development of GIAD and the current roles of endoscopic, medical, and surgical therapy in its treatment...

BACKGROUND: Ethiopia has made remarkable progress in reducing child mortality over the last two decades. However, the under-5 mortality rate in Ethiopia is still higher than the under-5 mortality rates of several low- and middle-income countries (LMIC). On the other hand, the patterns and causes of child mortality have not been well investigated in Ethiopia. The objective of this study was to investigate the mortality trend, causes of death, and risk factors among children under 5 in Ethiopia during 1990-2013...

BACKGROUND: Thrombocytosis (or, less commonly, thrombocytopenia) is associated with iron-deficiency anemia and resolves with iron therapy. Many volunteer blood donors have low iron stores, with or without anemia. Iron balance could affect platelet counts in blood donors. STUDY DESIGN AND METHODS: Whole blood donors deferred for finger-stick hemoglobin levels less than 12.5 g/dL were evaluated by complete blood count and serum iron panel before and after oral iron treatment...

BACKGROUND: The prevalence of iron-deficiency anemia (IDA) is high in infants in Sub-Saharan Africa. Exclusive breastfeeding of infants to 6 months of age is recommended by the World Health Organization, but breast milk is low in iron. Some studies suggest exclusive breastfeeding, although beneficial for the infant, may increase risk for IDA in resource-limited settings. OBJECTIVE: To determine if duration of exclusive breastfeeding is associated with anemia and iron deficiency in rural Kenyan infants...

BACKGROUND: Severe anemia is a major cause of sickness and death in African children, yet the causes of anemia in this population have been inadequately studied. METHODS: We conducted a case-control study of 381 preschool children with severe anemia (hemoglobin concentration, <5.0 g per deciliter) and 757 preschool children without severe anemia in urban and rural settings in Malawi. Causal factors previously associated with severe anemia were studied. The data were examined by multivariate analysis and structural equation modeling...

The importance of iron deficiency as a public health problem is based ultimately on the seriousness of its consequences on health. The most extensively investigated consequences of iron deficiency involve work performance and immune function. The significance of the effects on work performance is generally accepted. In contrast, data on the influence of iron deficiency on immune function are often perceived as being confusing and contradictory.We aimed to evaluate the effect of iron deficiency anemia on humoral, cellular, nonspecific immunity, and also the effect on the cytokines that are the key factors of many immunologic steps...

After the age of 65 years, iron deficiency anemia (IDA) requires the elimination of digestive neoplasia and is explored with upper and lower gastrointestinal (GI) endoscopy. However, such explorations are negative in 14% to 37% of patients. To further evaluate this issue, we evaluated the outcomes of patients aged over 65 years with endoscopy-negative IDA.We retrospectively analyzed the outcomes of in-patients over the age of 65 years with IDA (hemoglobin <12 g/dL and ferritin <70 μg/L) who had negative complete upper and lower GI endoscopies in 7 tertiary medical hospitals...
