The Impact of COVID-19 Infection on the Symptoms of Functional Dyspepsia

Dyspepsia

Although respiratory symptoms were predominant in patients infected with COVID-19, gastrointestinal symptoms were always reported in about 10% patients. Previous studies demonstrated that the SARS-CoV-2 virus still persists in stool samples for a long time after initial infection. Moreover, some patients had a longer duration of COVID-19-related gastrointestinal symptoms, which was defined as "post-acute COVID-19 syndrome". Previous studies have shown that functional gastrointestinal disorders may occur after acute gastroenteritis. Functional dyspepsia (FD) is one of the most common functional gastrointestinal disorders. FD was reported to be correlated with multiple pathophysiological mechanisms, including GI bacterial imbalance, disordered gut microbiota, and disturbed barrier and immune function. It is unknown whether COVID-19 infection could exacerbate the symptoms of FD. Therefore, we followed up a group of FD patients before and after COVID-19 and investigate the impact of COVID-19 infection on the symptoms of FD.

GastroparesisDiabetes Complications2 more

Electrogastrogram (EGG) is a non-invasive method for recording myoelectric activities by placing electrodes on the abdomen surface. Many studies suggested EGG measures the gastric slow wave frequency effectively; the relative change in EGG signal amplitude would reflect the contractility of the stomach. Thus, this technique is used to study the pathophysiological processes of diseases such as functional dyspepsia and many more . The present study aims to study the EGG pattern in healthy individuals in Indian population and the factors associated with it.

Clinical Course of Functional Dyspepsia and Factors Predicting Outcome in Patients Receiving Medication-based...

Functional Dyspepsia

Functional dyspepsia (FD) is one of most common chronic gastrointestinal disorders. Several types of drugs were demonstrated to be effective in reduction or remission of symptoms and severity of FD, including proton pump inhibitors (PPI), Tricyclic antidepressant and prokinetics. However, the clinical course of FD after taking medication-based treatment was unknown. Furthermore, 20-50% patients remained persistent or worsening of dyspepsia symptoms after treatment. Previous studies have suggested psychological factors (eg. anxiety, sleep disturbance) were related to less improvement of symptoms in natural clinical course. However, there is limited evidence in terms of clinical and psychological factors for less improvement in patients receiving medication treatment for dyspepsia.

Primary carE PPi dEprescRibing Trial

HeartburnDyspepsia1 more

Proton pump inibitors (PPIs) is a class of medications that reduce the acid secretion in the stomach. These medications are very effective to relieve symptoms of acid reflux for a well-identified group of diseases and conditions. Over the years, a major rise in use of these drugs has occurred. Convincing analyses reveal that a large share of this use occurs outside regular indications, at inappropriately elevated doses and prolonged treatment durations. Moreover, there are increasing concerns regarding potential adverse effects and the high cost associated with improper PPI use. Guidelines propose to reduce chronic use of PPIs, but to date this has not generated a reduction in their application in clinical practice. One reason is the occurrence of a period of 2 weeks of increased acid secretion, with recurrence of symptoms, when these drugs are stopped after already a few weeks of usage (rebound effect). The best strategy to overcome this period of increased acid secretion and symptoms has not been established. The PEPPER study will evaluate two different strategies to overcome the period of increased secretion when trying to interrupt chronic proton pump inhibitor therapy. The investigators will compare the success of stopping PPIs when these strategies are implemented, compared to a classical strategy of stopping after intermittent PPI intake. The strategies under evaluation are a period of non-daily intake of proton pump inhibitors (on-demand) before stopping, or the use of alternative methods to control gastric acidity and reflux (so-called alginates). The investigators will evaluate the success rate of stopping chronic PPIs treatment with these approaches, compared to an interruption with intake of antacids. Patients will be followed up for 1 year after interruption of PPIs, and the level of symptom control, quality of life and healthcare costs will be evaluated at intervals. The study will be conducted in patients from primary care practices with chronic PPIs intake outside of the established disease indications.

Mechanisms of Electroacupuncture for Functional Dyspepsia Based on "Enterotypes" and Metabolomics...

Functional Dyspepsia

The goal of this clinical trial is to explore the clinical efficacy and possible mechanisms of electroacupuncture treatment for functional dyspepsia (FD). The main question it aims to answer are: Differences in the effects of electroacupuncture and sham electroacupuncture intervention on FD. Differences in gastrointestinal hormone levels and gut microbiota and their metabolites between healthy individuals and FD patients. Participants receive electroacupuncture and sham electroacupuncture interventions respectively. Before and after the intervention, the clinical symptom score, gastrointestinal symptom evaluation scale, gastrointestinal symptom score questionnaire, and functional dyspepsia quality of life scale of the subjects will be observed. The levels of gastrointestinal hormones MTL, Ghrelin, 5-HT, CCK, PYY, and GLP-1 will be measured, as well as the changes in microbial diversity and SCFAs in their metabolites in feces, A follow-up visit will be conducted one month after the intervention for all participants.

Association of Multiple Medications With the Severity of Dyspepsia

Dyspepsia

Dyspepsia is a very common gastrointestinal disease. Some medications, were associated with higher frequent incidences of dyspepsia, including non-steroid anti-inflammatory drugs (NSAIDs), Bisphosphonates, Tetracyclines, et al. Multiple medications were suggested to be strongly relate to adverse drug events (ADEs), adverse drug reactions (ADRs), drug-drug interactions, and drug-disease interactions, which may cause gastrointestinal(GI) dysfunction or injury to the GI mucosa. However, it was unclear whether multiple medications was associated with more severe symptoms of dyspepsia and dyspepsia-based score systems.

Biomagnetic Characterization of Gastric Dysrhythmias III

Diabetics Without Symptoms of GastroparesisDiabetic Gastroparesis4 more

There is a tremendous clinical need for a noninvasive technique that can assess gastric electrical activity and would be repeatable without any exposure to radiation. Investigators developed a new technique allowing to use noninvasive methods to assess bioelectrical activity in the gastrointestinal system. This has enabled to characterize the normal and pathologic physiology of the stomach through the use of noninvasive magnetogastrogram (MGG) records. Primary hypothesis for this proposal is that analysis of gastric slow wave uncoupling and propagation in multichannel MGG discriminates between normal and pathological gastric electrical activity. Eventually, investigators envision this research leading to new insights for gastrointestinal conditions such as gastroparesis, functional dyspepsia and chronic idiopathic nausea that would inform clinical management of these debilitating diseases.

Body Surface Gastric Mapping to Evaluate Patients With Upper Gastrointestinal Symptoms and Controls...

Motility DisorderGastroparesis4 more

This is an analytical validation observational cohort study is designed to provide evidence of: safety and reliability of Body Surface Gastric Mapping using the Gastric Alimetry System (GAS), normal reference values, and correlation of metrics with patient symptoms among healthy adults and patients diagnosed with upper abdominal motility disorders. GAS is intended to record, store, view and process gastric myoelectrical activity. This is a proprietary system consisting of multiple electrodes arranged on an array that is placed precisely over the stomach, a reader to collect the electrode measurements and a smart tablet application to track patient reported symptoms. Participants meeting inclusion and exclusion criteria will continue fasting for 30 minutes after the Gastric Alimetry System has been applied and begun measuring, eat a standard study meal within 10 minutes and remain quietly seated, reclining, for 4 hours as the GAS continues to collect data. The array is removed and the abdomen is examined for evidence of skin effects.
