Filter by:In up to half of patients seen by gastroenterologists, routine examinations fail to find an underlying organic, systemic, or metabolic disease that readily explains the symptoms. These patients are referred to as patients with disorders of gastrointestinal function, of which functional dyspepsia (FD) is one of the most common. Despite intensive research to investigate various pathophysiological mechanisms of this disease, the pathogenesis remains obscure. The investigators recently demonstrated increased duodenal permeability in FD patients, as assessed by mounting routine endoscopic duodenal biopsy specimens into Ussing chambers to measure transepithelial electrical resistance and passage of a paracellular fluorescent probe. Impaired intestinal barrier function can lead to increased uptake of luminal substances which can induce an immunological response in the mucosa. Interestingly, using transmission electron microscopy (TEM) in duodenal biopsies, the investigators recently observed the presence of a yet to be identified microorganism inside the epithelium and the lamina propria of a subset of FD patients (unpublished observations), suggesting increased translocation of microorganisms. The aim of the project is to investigate whether FD patients display increased translocation of microorganisms in duodenal biopsies. The investigators will also test the effect of bile acid on translocation of microorganisms and therefore include 20 FD patients and 20 age- and gender-matched healthy volunteers in this study.
Chronic atrophic gastritis (CAG) is acknowledged as the precancerous stage of gastric cancer (GC). The present study aims to developed risk assessment and syndrome evolution models of CAG malignant transformation events combining TCM indicators with modern medicine indicators. The proposed study is a registry study based participant survey conducted in 4 hospitals in Beijing, China. After obtaining informed consent, a total of 2000 study patients diagnosed with CAG will be recruited. 10-year follow-ups are carried out on-site in hospitals and off-site by telephone to track malignant transformation events.
Detection of Volatile Organic Compounds (VOC) directly from tissue by headspace analysis (skin, surgery material, other tissue) and exhaled breath is feasible using affordable user-friendly novel nano-chemo sensors that can accurately be used for screening and monitoring purpose
This study is a multi-center, randomized, active-controlled, double-blind, non-inferiority, phase III clinical trial evaluating efficacy and safety of once-daily mosapride (UI05MSP015CT) in patients with functional dyspepsia.
The purpose of this study is to evaluate the safety and efficacy on participants receiving first-line eradication and second-line eradication including vonoprazan (Takecab) tablets (triple therapy) in the routine clinical setting.
THe purpose of this study is to evaludate the Efficacy and Safety of DWC20155/DWC20156 Combination Therapy in Patients with Gastritis
The purpose of this study is to evaluate the Efficacy and Safety of DWJ1252 in treatment of Functional Dyspepsia.
Background: Non-specific neck pain (NS-NP) is characterized by pain in structures located in the region between the superior nuchal line and the spinal process of the first thoracic vertebra, without association with any specific systemic disease provided by multifactorial and/or little known causes. Objective: The objective of the present study will be to verify the clinical effects of MV through visceral nociceptive inhibition in NS-NP patients with functional dyspepsia. Methods: In this study sixty NS-NP patients with functional dyspepsia (age: 18 and 50 years) will be randomized in into two groups: visceral manipulation group (VMG) (n =30) and control group (CG) (n =30). The VMG will be treated with visceral manipulation to the stomach and liver wile CG received placebo treatment. The immediate effects and 7 days after treatment will be evaluated through pain, cervical range, and electromyographic activity of the upper trapezius.
The purpose of this study is to evaluate the Efficacy and Safety of DWJ1252 in treatment of Functional Dyspepsia.
Dyspeptic symptoms such as abdominal pain, bloating and nausea after a meal are common; however the cause of these problems in many patients is often unclear despite medical investigation. This is because "dyspeptic symptoms" are only rarely related to acid reflux, stomach ulcers or cancer that can be diagnosed by endoscopy. Rather, the cause is abnormal stomach function, so-called "functional dyspepsia", a condition in which the digestive system does not function normally after a meal. Gastric scintigraphy is the standard investigation of stomach function in patients with this condition. It involves eating a small test meal that includes a tiny dose of radioactive material so that the movement of food can be visualised as it empties from the stomach. An important limitation of this approach is that symptoms are rarely caused and delayed emptying after a small meal is present only in a minority of patients and, thus, the ability of this investigation to explain the cause of symptoms or guide medical treatment is limited. This research project is designed to compare three new investigations of stomach function using a relatively large meal. This information will help to explain the causes of symptoms after a meal. The investigations to be tested include: (1) Nutrient Drink Test, (2) Gastric Scintigraphy and (3) Magnetic Resonance Imaging. All three tests are safe, easy to perform and non-invasive (i.e. do not involve inserting catheters through the nose and into the stomach or taking blood). The results should provide more useful information to doctors looking after patients with dyspeptic symptoms. This study will compare test results from healthy volunteers, with patients attending clinic for investigation of dyspeptic symptoms. The aim is to document abnormal function of the stomach and intestines and to identify the causes of dyspeptic symptoms after a meal.
