Preoperative Intravenous Iron Therapy in Patients With Gastric Cancer
Gastric CancerAnemia3 moreThe main objective of this investigator initiated study is to study if preoperative intravenous iron is effective in reducing need for allogenic blood transfusion in patients with gastric cancer who will undergo a standardized gastrectomy including both total and subtotal gastrectomies. The hypothesis is that intravenous iron reduces the need for perioperative blood transfusions.

AnemiaIron DeficiencyA randomized, double-blind, parallel, three-arms, placebo-controlled, safety and efficacy study of Botanical Extract Standardized for Iron + Vitamin C and Botanical Extract Standardized for Iron in adult human subjects with anemia or iron-deficiency anemia. A total of up to 96 adult male and female subjects of age 26 to 55 years (32 subjects/arm) will be enrolled to get 90 evaluable subjects (30 subjects/arm) in the study
Depth of Maximal Ileal Insertion During Retrograde Enteroscopy With TTS Balloon
Obscure Gastrointestinal BleedingAnemia1 moreDiagnostic modalities for the evaluation of small bowel pathology include video capsule endoscopy (VCE), antegrade and retrograde device-assisted enteroscopy, CT and MR enterography (1). Despite VCE being the first-line evaluation modality, it lacks interventional capability. Deep enteroscopy (DE) allows tissue sampling and other therapeutic interventions with real-time endoscopic assessment. DE is usually performed with specific endoscopes (balloon-assisted device or spiral overtube) making it time consuming and there is limited availability since special instruments and accessories are required.(1,2) The through-the-scope (TTS) balloon system consists of a balloon catheter designed for anchoring in the small bowel, inserted through the instrument channel of a standard colonoscope.(3) The catheter is advanced, the balloon is inflated and anchored in the small intestine and the endoscope slides over the guiding catheter to the inflated balloon. The most common indications for DE are obscure GI bleeding, iron deficiency anemia, abnormal capsule endoscopy and chronic diarrhea. As compared to spiral, single-or double-balloon enteroscopy, TTS (NaviAid, SMART Medical Systems Ltd, Ra'anana, Israel) is a simpler technique, which requires less investment in infrastructure. The balloon catheter is advanced blindly in front of a standard adult colonoscope as it bends around the curves of the small bowel. To prevent perforation/trauma the catheter is fitted with a soft silicone tip which easily bends under pressure. Insertion depth can be calculated during the withdrawal of the enteroscope. The Aim of the study: To compare the depth of maximal ileal insertion between through-the-scope balloon enteroscopy (NaviAid) with enteroscopy using the adult colonoscope (Olympus CF-190) alone, in the same patient, in a prospective cohort at University Medical Center of El Paso, Texas.
Ethnic Differences in Iron Absorption (FeGenes)
AnemiaIron Deficiency1 moreThis study aims to; 1) investigate population differences in iron absorption between East Asians and Northern Europeans; 2) assess population differences in hormonal and biochemical determinants of Fe absorption between East Asians and Northern Europeans; and 3) to investigate genetic contributions to Fe absorption, Fe status and Fe regulatory hormones between East Asians and Northern Europeans.
Iron Deficiency in Patients With Heart Failure and Reduced Evection Fraction
Iron DeficiencyHeart Failure With Reduced Ejection FractionAbout half of patients with heart failure and reduced ejection fraction (HFrEF) have iron deficiency who are symptomatic. This is independently associated with bad quality of life, low functional capacity, lower quality of, life and increased mortality. The prevalence of iron deficiency in HFrEF patients in Jordan has not been studied in the past.
Neurovascular Complications and White Matter Damage in Acquired Anemias
AnemiaIron-deficiency Anemia1 moreThis is an observational trial, in patients with moderate to severe anemia and control subjects. The main purpose of this study is to understand whether normal brain blood flow, oxygen extraction reserve, white matter volumes, and brain functional connectivity are affected by acquired anemia. The investigators will perform baseline MRI monitoring for all subjects. All eligible subjects will be asked to provide informed consent before participating in the study.
Prevalence of FID and QoL in Patients With Oncological and With Haematological Malignancies
Functional Iron DeficiencyProspective single-center observational study assessing prevalence of FID (Laboratory work-up) and Quality of Life (Questionnaire) in adult patients with oncological and with haematological malignancies within four weeks prior to disease-directed therapy.
Effects of Preoperative Correction of Anemia With Intravenously Iron in Colorectal Cancer Patients....
Colorectal CancerAnemia1 moreThe aim of the study is to examine the effects of anemia correction with intravenous administered iron on clinical outcomes and the immune response on the tumor in patients with planned colonic- or rectal cancer surgery. The study will be performed as a retrospective propensity score-matched cohort study with an examination of immune response in tumor and clinical outcomes, between patients with anemia without correction with iron(III)isomaltoside, non-anemic patients, and anemic patients treated with iron(III)isomaltoside prior to surgery. Propensity score matching will ensure identification of controls from a pool of patients treated at the Department of Surgery, Zealand University Hospital. The two control groups will be: an anemic historical control group (group 1), and a non-anemic concurrent control group (group 2). Group 3 will be the treatment group, with patients with anemia and treated with iron(III)isomaltoside. The study period of cases undergoing i.v. treatment will be 1st of February 2017 to 31st of October 2019 with approximately 70 cases included
Impact of Intravenous Iron on Musculoskeletal Function in Older Adults
Iron Deficiency AnemiaAnaemia is a risk factor for functional decline and frailty in older adults including decreased physical performance and muscle strength, increased hospitalisation risk and mortality, falls, and poorer recovery from activities of daily living. Despite a major gap in human studies, research in animals has demonstrated an interrelationship between iron deficiency anaemia and deteriorated functional capacity and physical performance particularly in older adults. Iron deficiency and associated anaemia is a frequent accompanier of debilitating chronic diseases such as heart failure and chronic lung diseases. These conditions, more commonly seen in older patients, are strongly linked to deterioration in physical function, reduced skeletal muscle mass and quality, frailty, and poor quality of life. Exercise intolerance is also a common feature of these conditions as iron deficiency impairs the capacity of carrying oxygen leading to inability to sustain physical activities. Furthermore, the age-related decline in the muscle mass and quality (so called sarcopenia) and associated frailty has rapidly become a major health concern in the older adults particularly when accompanied by other chronic diseases. Recently, there has been an increasing interest in exploring the role of iron as a causative factor in the development of sarcopenia and related frailty. In summary, there is a substantial gap of evidence whether Iron repletion leads to meaningful enhancements in the skeletal muscle function and physical performance in older adults suffering from iron deficiency anaemia. This study will investigate the impact of a standard care intervention (intravenous iron therapy) on muscular function and physical performance in older patients through a range of laboratory assessments.
Iron Deficiency Anemia
IDA - Iron Deficiency AnemiaAnemia3 moreThis is a trial with an observational and an interventional arm, in patients with moderate to severe anemia and control subjects. The main purposes of this study is to phenotype the scope of neurocognitive deficits from iron deficiency anemia (IDA) in adult women, determine derangements in cerebral perfusion, vascular reactivity, functional connectivity, and blood brain barrier permeability in adult-onset IDA and relate them to neurocognitive deficits, as well as determine the reversibility and durability of both the physiologic and neurocognitive derangements by iron replacement therapy. All eligible subjects will be asked to provide informed consent before participating in the study.
