Active clinical trials for "Deficiency Diseases"

This is a pilot prospective single blind controlled trial comparing magnetically steerable gastric capsule endoscopy to conventional oesophagogastroduodenoscopy in diagnosing upper gastrointestinal pathology in patients with recurrent/refractory iron-deficient anaemia.

The role of capsule endoscopy (CE) in patients with obscure / occult gastrointestinal (GI) bleeding remains unclear. This pragmatic randomized controlled trial is designed to determine the diagnostic yield and clinical outcomes of patients with obscure GI bleeding who receive CE compared to those who receive usual standard care.

The purpose of this study is to evaluate the feasibility and effectiveness of weekly iron and folic acid (IFA) supplementation and one-time deworming treatment at the community level in improving hemoglobin levels among adolescent girls in Liberia, West Africa, and to assess the feasibility and effectiveness of a targeted nutrition education program in improving nutrition knowledge, attitudes, and practices in the same population.

The objective is to determine if a set of clinical supports that includes computer-assisted identification, an EHR registry, facilitated GI referral, and an EHR tool for documentation improves the timely referral and completion of bidirectional endoscopy in men aged 18 years and older and women aged 40 years and older with iron deficiency anemia.

The purpose of this study is to monitor and quality assure the efficacy and safety of Monofer® in a broad patient population when Monofer® is used according to the Monofer® label (SPC) in current practice and where standard routines are being followed.

This study will try to determine if intake of dietary fats or carbohydrates influences the tendency to gain weight or accumulate body fat. It will examine how the hormones that regulate weight may change with a shift from a balanced diet to one that is low in fat or carbohydrate, irrespective of caloric intake. Men and women between the ages of 18 and 40 years with a body mass index of 30 to 49 kg/m2 may be eligible for this study. Candidates will be screened with a history, physical examination, blood tests and questionnaires regarding activity, prior diets, and eating patterns. Participants will follow two separate diet regimens for 5 days each. The first will be a balanced diet, and the second will be either a low-fat/high-carbohydrate diet or a low-carbohydrate/high-fat diet. The diets are not designed to produce weight loss. Participants will receive all their meals and snacks for the two diets from the National Institutes of Health and, for the first 3 days of each diet, will be seen as outpatients. For days 4 and 5 of each diet, they will be admitted to the Clinical Center and will undergo the following procedures: Blood tests - Blood samples will be collected every 30 minutes over a 24-hour period through an indwelling catheter in the arm. A total of about 15 tablespoons will be drawn for each of the two diets. 24-hour urine collection - One 24 hour urine collection will be done at home the day before admission to the Clinical Center, and the other will be done during the hospital stay. Urinalysis and pregnancy test - A small urine sample will be taken and women will provide an additional sample for a pregnancy test. Body measurements - Height and weight will be measured using scales. Body fat will be measured by two methods: skin fold thickness, measured with calipers in 5 separate places; and body circumference measurements, in which body parts are measured with a tape measure. Bod pod measurement - Proportions of fat and non-fat tissue in body weight are measured while the participant sits in a capsule-like device for 5 minutes. Bioelectric impedance analysis - Proportions of body fat are measured based on conduction of a small electric current. Total body water estimate -The proportion of body weight that is water is determined, using a method that involves drinking a cup of a special kind of "heavy" water (deuterium) and then measuring the amount of heavy water in a urine sample taken after 4 hours. Exercise - Participants will maintain their usual exercise routine, as it was before beginning the study.

Nowadays up to 40% of patients undergoing cardiac surgery receives at least 1 unit of red blood cell transfusion during surgery or during the first week after surgery. Moreover up to 40% of these patients shows an absolute or relative iron deficiency, with or without anaemia. The objective of this study is to assess whether to implement an adequate correction of iron according to current "patients blood management" recommendations might reduce RBC transfusion requirements in patients undergoing heart surgery. Data obtained in patients included in the study will be compared to those of a case-control population selected from patients consecutively treated at the same department in the previous 2 years.

The investigators will retrospectively collect data of patients infused at UMC's emergency department (ED) with long acting irons (ferric carboxymaltose, iron dextran, iron sucrose, etc.), in addition, patients infused with blood products, with intent to treat iron deficiency anemia (IDA). Patient records reviewed will be from patients who were infused at UMC ED from January 2013 to June 2018. Primary aim of analysis will be to investigate superiority between interventions implemented for treating IDA. In addition, the investigators will utilize data to characterize patients who used ED services as an avenue to receive treatment for IDA. Further, the investigators will conduct cost analysis between different IDA directed treatments administered in the ED at UMC.

This research is being done to construct a survey questionnaire, a quality of life tool, to determine the health, well-being, ability to perform daily activities, and physical, social and emotional functioning in participants with primary immunodeficiency disorders (PIDD). This quality of life (QOL) tool will help physicians understand the effects of PIDD on a person's health. These quality of life surveys are important tools for physicians to measure outcomes for satisfaction and effects of treatment.

The objective is to monitor and quality assure the efficacy, including effects on quality of life, and safety of Monofer® in Chronic Kidney Disease and Inflammatory Bowel Disease patient populations when Monofer® is used according to the Monofer® label (Summary of Product Characteristics, SPC) in current clinical practice and where standard routines are being followed.
