Active clinical trials for "Malabsorption Syndromes"

The purpose of this trial is to determine the efficacy and safety of A3384 administered to patients with Bile Acid Malabsorption (BAM)/Bile Acid Diarrhoea (BAD).

The purpose of this study is to evaluate the effectiveness and safety of PANCREASE MT (pancrelipase microtablets) to improve steatorrhea (excessive excretion of fat in feces) in infants and toddlers with cystic fibrosis who have pancreatic insufficiency, and to assess whether the consistency of the microtablets is acceptable for swallowing in infants and toddlers

To evaluate the pharmacokinetic parameters of orally administered 25-hydroxyvitamin D3 [25(OH)D3] and vitamin D3 from the corresponding serum concentration-time curves in healthy adults and adults with a history of intestinal malabsorption.

Bile acid diarrhoea is a chronic disease that impairs quality of life. One in 100 has the condition and many suffer from the disease without knowing. The current test is called SeHCAT and is expensive and time-consuming and is unavailable in many places, including the US. The disease is often misdiagnosed as irritable bowel syndrome and estimated one third of patients with irritable bowel syndrome of the mixed type and the diarrhoea predominant type suffer from bile acid diarrhoea without knowing. A blood test called 7α-hydroxy-4-cholestene-3-one (C4) could make it much easier to diagnose bile acid diarrhoea. To establish the new test, the results of both C4 and SeHCAT are compared with the treatment effect of the drug called colesevelam. We invite patients who are referred for the SeHCAT test to participate in the trial. The SeHCAT test takes two days that are one week apart. The study patients register stool habits with a diary in the week between the SeHCAT visits. Based on the diary results, we screen for eligibility; e.g. a certain degree/severity of diarrhoea is required for participation. We treat eligible study patients (i.e those with diarrhoea) with either colesevelam or placebo (medicine without effect) that is randomly assigned. 170 study patients need to complete the treatment. We aim to validate (ie. compare) both the C4-test and the SeHCAT test with the colesevelam treatment response as the reference.

Different published studies has shown a possible co-variation between leakage of fructose to the great bowel and exacerbation of irritable bowel syndrome (IBS) symptoms. The aim of the FINN trial is to study the role of fructose malabsorption in patients with IBS in order to evaluate different diagnostic criteria for fructose malabsorption and at the same time study the effect of diet treatment in this cohort of patients and estimate the prevalence of fructose malabsorption.

Fermented dairy products, especially real Yoghurt, are often tolerated better by lactose malabsorbers than unfermented dairy products. The intake of dietary supplements containing acid Lactase derived from Aspergillus oryzae with lactose containing foodstuffs is known to reduce/alleviate symptoms of lactose intolerance in lactose malabsorbers. The study aims to compare the effect of the intake of a combination of yoghurt bacteria and acid lactase to the effect of yogurt bacteria or acid lactase alone on the lactose digestion in lactose malabsorbers. It is hypothized that the combination preparation will be more effective and/or will show a more reliable effect than the two mono-preparations.

The investigators propose to develop studies of obeticholic acid (OCA) in patients with bile acid diarrhoea. OCA is a semisynthetic bile acid, also known as 6αethylchenodeoxycholic acid or INT747,and is a potent farnesoid X receptor (FXR) agonist. Preliminary data suggests that patients with bile acid diarrhoea have impaired production of the ileal hormone Fibroblast Growth Factor 19 (FGF19). FGF19 is stimulated by FXR agonists, and regulates bile acid synthesis. This study is a pilot, proof-of-concept, open-label study to investigate whether OCA can stimulate FGF19 in bile acid diarrhoea patients to provide a safe and effective treatment.

Iron deficiency is the most common cause of anemia in pregnancy worldwide, and, when severe, can have serious consequences for mothers and babies. While treatment of iron-deficiency anemia with iron supplementation is recommended, treatment strategies remain controversial: the American College of Obstetrics and Gynecology recommends oral iron supplementation with parental iron reserved for the rare patient who cannot tolerate or will not take oral iron, while UK professional organizations recommend a more liberal use of parenteral iron. The reason for these disparate recommendations is that few high-quality studies comparing oral to parenteral iron have been conducted in developed countries, and the potential impact of parental iron treatment on obstetric and perinatal outcomes remains unclear. We propose the first randomized-controlled trial in the United States describing the effectiveness and safety of treating pregnant women with iron-deficiency anemia with a protocol including parenteral iron compared with a protocol based on oral iron.

A randomized, double-blind, placebo-controlled clinical study in non-homozygous human leukocyte antigen (HLA)-DQ.2.5+ adults with celiac disease (CeD).

There is some controversy in the medical literature regarding the effectiveness of topical lidocaine in children as an adjuvant drug to upper gastrointestinal endoscopy. In children, deep sedation and general anesthesia are often used to sedate children submitting to this procedure. Propofol is an anesthetic drug increasingly popular in this situation, but this drug can only be used with an anesthesiologist in Brazil. Its main side effects include hypotension, respiratory depression and local pain. Lidocaine is frequently used as premedication, and the rationale is that lowering patient discomfort could lower the required dose to achieve the endoscopy and reduce potential side effects. Nevertheless, some patients perceive this medication as uncomfortable. This study aims to compare sedative drug doses between patients who were given either placebo or topical lidocaine.
