Active clinical trials for "Anemia, Iron-Deficiency"

Critical patients which requiring admission to intensive care (IT) are a special group of patients. In these patients the prevalence of anemia reported in studies is 75%. This prevalence is similar to that in the retrospective observational study conducted in our intensive care unit(ICU). Of the 783 patients included in the study, 551 (73.37%) had anemia on admission. Frequently anemia is present on discharge from ICU or hospital and may persist for an average of 11 weeks. Some studies have reported the presence of anemia as far as 6 months after discharge. It is widely accepted that anemia has a negative impact on rehabilitation and quality of life, but the treatment can not be exclusively based on blood products due to the risks associated with transfusion. Alternative treatments such as injectable iron or erythropoietin should be considered. The Transfusion Management Initiative Group recently issued recommendations on perioperative anemia. Similar recommendations for ICU have not yet been developed in Romania. The current study has two main purposes. The first to adopt the perioperative anemia diagnostic algorithm and adapt it to anemic patients on ICU; the second to identify patients with mixed anemia (inflammatory and iron deficient anemia) who can benefit from treatment with iron.

As combat women soldiers are required to more intensive daily activity the investigators believe that the impact of menorrhagia, dysmenorrhea and its clinical consequence (as characterized by, anemia iron deficiency and reduced quality of life)) on personal performance will be more significant in combat women soldiers compared to non-combat women soldiers. Using cohorts from the same environment will enable the investigators to better study the effect of menorrhagia and dysmenorrhea eliminating other uncontrolled factors, such as nutrition. The study does not include any intervention.

Iron deficiency is considered one of the main nutritional deficiency disorders despite the apparent availability of a high-quality diet even in developed countries, and Iron deficiency anemia (IDA) is the most common form of anemia in the world. IDA during pregnancy has been associated with adverse health consequences for both the mother and her developing fetus. Helicobacter pylori (Hp) may be the most common bacterial infection worldwide, infecting almost half of people in developed countries and 80% of people in developing countries. The available data on the prevalence of Hp infection in Taiwan population was 54.4%. We all know that infection with Hp is strongly associated with peptic ulcer and gastric cancer, but recent evidence suggests that Hp is associated with iron deficiency and anemia, although the mechanisms remain unclear. Till now, only few previous studies specifically have addressed a potential role of Hp infection on anemia or iron deficiency during pregnancy. Our previous Research showed, between the Hp infection (+) and Hp infection (-) gravidas, the associations between the Hp infection and iron deficiency were stronger, although not statistically significant. This might be due to that we needed more cases and evidences to prove the relationship between maternal Hp infection and serum iron, ferritin and hemoglobin levels, or we should further consider the interactions of the particular customs or diet preference of the Taiwanese gravidas. This longitudinal study will recruit 140 women from the antenatal care clinics of E-Da Hospital to examine the association between Hp infection and maternal IDA. The standardized interviews of mothers (anthropometric data, socioeconomic status, medical history, obstetric history, alcohol consumption during pregnancy, and history and duration of iron supplementation during pregnancy) will be conducted, Hp infection status will be determined by the urea breath test and IgG enzyme immunoassay, and the measurement of hemoglobin, iron, and ferritin levels will be obtained 5 times at various antepartum and postpartum points of time during pregnancy (routine prenatal visits of 1st, 2nd, and 3rd trimester, puerperium and 2 weeks after delivery). We hope that we could investigate the possible role of Hp infection in iron deficiency and iron-deficiency anemia during pregnancy in Taiwan, and that early detection and treatment of anemia may reduce the risk of blood transfusion and perinatal and maternal mortality.

The purpose of this project to examine brain functions and behavior related to ID including sensory ,motor, cognitive and social /emotional functioning, and address unanswered questions about brain and behavior impacts of different timing of ID(pre- and /or postnatal ID) in infants.

According to the World Health Organization (WHO), anemia is the most common disease, affecting >1.5 billion people worldwide. Furthermore, iron deficiency anemia (IDA) accounts for 50% of cases of anemia. IDA is common during pregnancy and the postpartum period, and can lead to serious maternal and fetal complications. Measurement of serum ferritin has the highest sensitivity and specificity for diagnosis of IDA unless there is a concurrent inflammatory condition. The lower threshold value for hemoglobin (Hb) in pregnant women is <11 g/dL during the 1st and 3rd trimesters, and <10.5 g/dL during the 2nd trimester. In postpartum period a Hb concentration <10 g/dL indicates clinically significant anemia. Oral iron therapy is given as the first-line treatment for IDA.

Red Cell Distribution Width Index versus Red Cell Distribution Width as Discriminating Guide for Iron Deficiency Anaemia and Beta Thalassemia Trait .

The purpose of this study is to describe the prevalence of anemia and iron deficiency in pregnancy through a multi-center, prospective follow-up study . To explore the influence factors of anemia and iron deficiency in pregnancy; to explore the influence of anemia and iron deficiency in pregnancy on maternal and fetal outcomes.

Diabetic foot ulcer is the commonest cause of severe limb ischemia in diabetes mellitus And development of anemia is an additional burden to the microvascular complications of diabetes

Both upper gastrointestinal endoscopy and colonoscopy are recommended in men and post-menopausal women with iron deficiency anemia. Due to lack of data on the yield of these endoscopies in young men, they are currently investigated as older men. The aim of this study is to evaluate prospectively the prevalence of various gastrointestinal lesions in young men with iron deficiency anemia. Our hypothesis is that the diagnostic yield of colonoscopy in young anemic men without gastrointestinal symptoms is very low, especially if a potential lesion is detected during upper gastrointestinal endoscopy. Therefore, this study will try to identify predicting factors regarding the yield of both endoscopies. Another purpose is to evaluate the outcome of patients with negative endoscopic results, during a follow-up of two years.

This is a sub-study nested into the existing NICHD Global Network for Women's & Children's Health Research Maternal Newborn Health (MNH) registry that is a prospective, observational population-based registry in Eastern Maharashtra, India. This study will assess the prevalence of iron deficiency anemia (IDA) and non-iron deficiency anemia (NIDA) in Eastern Maharashtra and will assess the association between both conditions and neo-natal and infant health outcomes (birth weight, gestational age at birth, weight-for-gestational-age z-score and infant hemoglobin concentration at 6 weeks). The investigators will also assess the relative strength of the association between anemia in the 1st trimester and 3rd trimester (after iron needs have increased but mothers may have been taking iron folic acid (IFA) supplements for several months) and infant health outcomes.
