The Efficacy of Sodium Butyrate and Probiotics in Patients With Irritable Bowel Syndrome

IBS-Plus
Start date: April 15, 2021
Phase: N/A
Study type: Interventional

According to current IBS management guidelines, probiotic administration reduces IBS-associated symptoms and improves the quality of life. The purpose of this study is to assess the effects of the combined formulation comprising microencapsulated sodium butyrate and a probiotic mixture of two Lactobacillus strains (L. rhamnosus and L. acidophilus) and three Bifidobacterium strains (B. longum, B. bifidum, and B. lactis) on the incidence and severity of clinical symptoms in patients diagnosed with irritable bowel syndrome (IBS) based on the Rome IV criteria. Microencapsulated sodium butyrate is a short-chain fatty acid (SCFA) with biological effects on the gastrointestinal mucosa; it constitutes a key source of energy for enterocytes. Butyrate was shown to have a trophic effect on the colon epithelium and to help restore the disrupted structural and functional integrity of the gastrointestinal tract. These unique properties of sodium butyrate result in its beneficial effects on the abdominal symptoms (such as diarrhea, constipation, abdominal pain) in patients with IBS. This study will assess the effects of the mixture of sodium butyrate and multi-strain probiotic on the rate and severity of clinical symptoms in IBS patients, by taking into account their nutritional status and body composition.

NCT ID: NCT05004207 Recruiting - Clinical trials for Irritable Bowel Syndrome

Study of Oro-cecal Transit Time in Healthy Subjects Using Scintigraphy and Lactulose Hydrogen Breath Test.

Start date: July 1, 2021
Phase:
Study type: Observational

Radionuclide scintigraphy is the gold standard technique to interpret OCTT but there is no normative data available for its interpretation in Indian population. Previous studies to determine OCTT have all been done with LHBT, which has many limitations. Besides there are few small comparative studies between scintigraphy and LHBT, that too not in Indian population. The aim of this study is to validate LHBT to measure OCTT compared with scintigraphy and to standardize the normal OCTT in healthy individuals

NCT ID: NCT05001997 Recruiting - Clinical trials for Irritable Bowel Syndrome

Effects of Lactose-free Dairy Products on Athletes With Irritable Bowel Syndrome

Start date: September 2021
Phase: N/A
Study type: Interventional

Irritable Bowel Syndrome (IBS) is a gastrointestinal disorder defined by recurrent abdominal pain, bloating, abdominal distention and altered bowel habits. IBS is common among athletes and can impair performance. IBS was found to be prevalent in 9.8% (n=430) of endurance athletes. The condition is associated with significantly reduced quality of life. IBS patients often attribute their gastrointestinal effects to lactose intolerance (LI) and may avoid/limit intake of dairy products. As LI and IBS share similar symptoms, IBS patients may wrongly attribute lactose intolerance as one of the causative factors and avoid dairy products altogether. Self-imposed reductions in consumption of dairy products could reduce calcium intake leading to reduced bone mineral density. This study aims to determine the prevalence of lactose malabsorption among athletes suffering from IBS and the potential of lactose free probiotics dairy products in alleviating gastrointestinal symptoms. The inclusion of probiotics dairy products in patients' diet will be beneficial in the long term to ensure adequate intake of calcium.

NCT ID: NCT04997057 Completed - Clinical trials for Irritable Bowel Syndrome With Constipation

A Multistrain Probiotic in Patients With Irritable Bowel Syndrome With Predominant Constipation

EPORE
Start date: January 4, 2022
Phase: N/A
Study type: Interventional

Probiotics efficacy is mainly assessed by subjective endpoints such as the FDA responder rate or global relief, which partly explain contradictory results obtained in clinical trials with probiotic bacteria. Objective biomarkers of IBS will allow to measure the efficacy of probiotics. In the case of IBS-C, serum resolvin-D1 appears to be an interesting candidate due to its non-invasive and discriminating character compared to a healthy population. It is, inversely correlated with the severity of symptoms. Resolvin-D1 modulates the duration and intensity of inflammation by regulating the transcription of cytokines, chemokines and their receptors as well as other proteins involved in inflammation. Resolvin D1 could serve as a predictor of probiotic response based on its baseline value.

NCT ID: NCT04993989 Completed - Clinical trials for Functional and Motility Related Gastrointestinal Disorders Such as Irritable Bowel Syndrome and Functional Dyspepsia

A Pharmacy-based Study to Learn More About How Well Iberogast Works, How it Affects the Body, How it is Used, and User Satisfaction in Patients With Functional and Motility-related (Stomach and Bowel Movement-related) Gastrointestinal Diseases, Including Irritable Bowel Syndrome

Start date: November 16, 2017
Phase:
Study type: Observational

Researchers want to learn more about the day-to-day use of Iberogast in people who have functional and motility-related gastrointestinal (stomach and bowel) diseases. Functional and motility-related stomach and bowel diseases are conditions in which the functionality of the gut, mainly the gut muscles or the gut/brain axis is disturbed. Functional and motility related stomach and bowel diseases cause symptoms like heartburn, cramps and u pain of the upper and middle part of the belly, also known as functional dyspepsia (FD), and irritable bowel syndrome (IBS). IBS affects predominantly the lower digestive system and causes symptoms like pain of the belly, cramps, bloating, diarrhea, and constipation. In this study, the researchers want to learn more about Iberogast, a plant-based treatment. Iberogast is available to treat stomach and bowel diseases such as FD and IBS. Earlier studies with Iberogast have shown how well it works and how it affects the body. But, little is known about the day-to-day use of Iberogast and how satisfied patients are who take it. So in this study, the researchers want to learn more about Iberogast including: - how well it works in day-to-day use - how it affects the body, also referred to as tolerability - how it is used day-to-day - how safe it is - how satisfied patients are who take it To answer these questions, the researchers will collect information from pharmacies in Germany. Patients who get Iberogast from these pharmacies to help treat their gastrointestinal disease will complete a questionnaire before, during and after taking Iberogast. The researchers will use the results from the questionnaires to learn more about: - the disease details of the patients who are taking Iberogast - the patients' symptoms while taking Iberogast - if the patients' symptoms change after taking Iberogast - how satisfied patients are with Iberogast - if the patients had adverse events An adverse event is any medical problem that a participant has during a study. This study will include patients in Germany who: - have functional stomach and bowel symptoms or disorders like FD or IBS - take Iberogast to treat symptoms of their stomach and bowel disease - are able to complete the questionnaire There will be no required tests or visits with a study doctor in this study. No treatments will be given as part of this study. The researchers will review information collected from patients who have decided for their own or by recommendation of their doctors or pharmacist to take Iberogast. The researchers will collect the results from the patient questionnaires from November 2017 to March 2018.

NCT ID: NCT04985669 Recruiting - Clinical trials for Patient Satisfaction

One group of patient will receive prucalopride 2mg daily and another group of patient will receive lubiprostone 8 microgram twice daily. IBS-SSS and IBS-QOL score will be recorded at baseline and at follow up at 3 week and 6 week. Effectiveness of both drug will be evaluated by comparing the baseline data with data at 3 week and 6 week(IBS-SSS and IBS-QOL).

NCT ID: NCT04974593 Recruiting - Clinical trials for Irritable Bowel Syndrome

Predictive Value of Hydrogen/Methane Lactose Breath Testing on the Therapeutic Effect of Lactose-free Diet in Moderate to Severe ROME IV IBS.

Start date: October 22, 2021
Phase: Phase 3
Study type: Interventional

Lactose intolerance (LI) results from lactose malabsorption (LM) secondary to insufficient hydrolysis of the disaccharide lactose into galactose and glucose (Misselwitz 2019). The undigested lactose will eventually reach the colon, resulting in fermentation from colonic bacteria with production of different compounds such as short chain fatty acids, carbon dioxide, H2 and methane (Catanzaro 2021). These compounds have an osmotic effect and can stimulate colonic contractions. These pathophysiological mechanisms encountered in patients suffering from LI generate symptoms, such as abdominal pain and cramps, flatulence, diarrhea, borborygmi among others. As dairy products are highly present in our Western diet, LI will often be considered in patients presenting with these symptoms and they will be referred for further testing. When LM is diagnosed, a lactose-free diet (LFD) will be advocated to alleviate symptoms. However, studies indicate that individuals with LM should tolerate up to 12 g of lactose when administered in a single dose (Suchy 2010). Irritable bowel syndrome (IBS) is another frequently encountered disorder. According to the Rome IV criteria, it is characterized by abdominal pain associated with a change in stool frequency or consistency, or with symptomatic improvement by defecation (Mearin 2016). Associated symptoms, such as bloating and flatulence, are frequently reported. As such, discerning between IBS and LI based on symptoms alone can be challenging. Moreover lactose is considered part of the so-called fermentable oligo-, di-, monosaccharides and polyols (FODMAPs). A low FODMAP diet has been advocated for IBS with beneficial response in at least part of the patients (Halmos 2014). Many studies investigated the role of lactose in IBS. These studies were performed in the pre-Rome IV era and before standardized interpretation rules for Hydrogen breath testing (H2BT) were published (meta-analysis by Varju 2019). This meta-analysis indicated that subjective LI was more frequently reported by IBS patients, but also objectively more prevalent in IBS patients, when assessed by any test modality. However, the role of a LFD in IBS remains uncertain. This study aims to: - Determine if the diagnosis of LM by H2BT predicts the short-term and long-term response to a LFD in moderate to severe IBS as defined by Rome IV criteria; - Determine the changes in quality of life in response to a LFD in ROME IV IBS patients.
