Active clinical trials for "Anemia, Iron-Deficiency"

Hypothesis: Correction of preoperative anemia can reduce the need for intra-/postoperative RBC transfusions and can improve surgical outcomes.

The purpose of this study is to identify the prevalence, nature and location of lesions in the GI tract that may contribute to iron deficiency anaemia and compare diagnostic yied of the upper GI magnetic controlled capsule endoscopy with conventional gastroscopy.

Vaccines often underperform in Africa compared to high-income countries. Why vaccines do not work as well in Africa remains uncertain. Malnutrition likely plays a role. Our study objective is to assess whether iron deficiency anaemia in young women impairs their immune response to viral vaccines, and whether iron treatment improves their response.

Food fortification is regarded as a safe and cost-effective approach to counteract and prevent iron deficiency. Rice is a staple food for millions of people living in regions where iron-deficiency anaemia is a significant public health problem. Therefore, rice may be a promising fortification vehicle. Hot and cold extrusion, have been identified as the major methods for rice fortification. Extruded rice has the advantage of incorporating vitamins and minerals into the food matrix. Cold, warm and hot extrusion differ in the processing temperature and the physical structure of fortified rice kernel matrix. A recent human study in young women showed fractional iron absorption was higher in cold extruded rice compared to hot extruded Rice and this was associated with changes in the starch microstructure. These changes cannot be detected in warm extruded rice, thus, our aim is to test the iron bioavailability in difference extrusion methods; hot and warm and cold with and without the solubilizing agent CA/TSC. This will provide information on optimized rice formulations for optimal iron delivery.

The burden of anaemia remains unacceptably high during pregnancy. Over a third of women are anaemic by their third trimester of pregnancy. The most common cause is iron deficiency. One key factor is rising iron requirements throughout pregnancy. There are risks associated with anaemia for the mother and infant. Anaemia in the first and second trimester has been significantly correlated with low birth weight and pre-term birth, and is associated with impaired neurological development of the baby. It also increases the risk of intrauterine fetal death, and the likelihood of the mother requiring blood transfusions during or after delivery.This study is a prospective cohort study, which aims to better define the natural history and understand how to use oral iron therapy for iron deficiency anaemia in pregnant women. This includes documenting the impact of treatment on anaemia symptoms, side effects, and the level of success of iron therapy using several haematological tests. Pregnant women will be invited to participate in this study and treated using a treatment schedule as described in national guidelines. Additional blood samples will be taken for subsequent detailed analysis of pathways of iron metabolism to better predict the response to oral iron therapy during pregnancy.

Co-design of a home-based anaemia monitoring system with participants who have previous diagnosis of anaemia.

In oncology, anemia is a frequent symptom, leading to complication of patient management for, more or less, a long term but often poorly evaluated by medical teams. In oncology, anemia is induced by multiple causes. Iron deficiency appears to be a leading cause of anemia, especially in people with solid cancer. Iron deficiency is characterized by a low level of iron . Iron is a trace element required for life. It is a major component of hemoglobin allowing the transport of oxygen in red blood cells. There are in fact 2 types of iron deficiency: an absolute iron deficiency with a deficiency of true iron and a functional iron deficiency. Since end of January 2014, intravenous iron-based injections have been reclassified for cancer patients at ICO Paul Papin. The monitoring of iron deficiency with or without anemia is currently done in our institute, the ICO-Paul Papin. There is a procedure for the management of anemia with or without iron deficiency but there is still no traceability of treatments performed, their compliance or even their impact on the rate hemoglobin and the quality of life of patients during their treatment. This observatory also makes it possible to evaluate the impact of this treatment on the quality of life of the patients and thus allows them a personalized care of the tiredness during their treatment

Slow release iron capsules containing ferrous sulfate have been designed based on the gastric delivery system. Iron absorption from those capsules administered with and without meals will be measured using stable iron isotopes.

Delayed clamping of the umbilical cord might prevent or slow the onset of iron deficiency by increasing the infant's iron endowment at birth. Compared to early clamping, a delay in clamping in clamping of around 2-3 min provides an additional 25-40 mL of blood per kg of bodyweight to the newborn infant. The results of previous intervention studies on delayed clamping are mixed, and few have followed the infants beyond the perinatal period. All longer follow up studies have been performed in low income countries except for the investigators earlier study, showing less iron deficiency and improved iron stores after delayed cord clamping at 4 months of age. The main objective of the current study is to assess whether the time of cord clamping affects neurodevelopment at 4 years of age in a large sample of full-term, Swedish infants. The investigators hypothesis is that as delayed cord clamping improves iron stores at 4 months, this could affect the child's development positively.

This study is initiated to investigate the effect of multi micronutrient supplementation for 12 months on serum haemoglobin level in Indonesian young children.
