Filter by:Constipation remains an important unmet medical need. Patients are currently often dissatisfied with treatment, because of lack of predictability of the laxative, side effects (mainly abdominal pain) and perceived decrease of efficacy with time. A recent systematic review of a range of laxatives reported that bisacodyl increases the number of complete spontaneous bowel movements statistically significant compared to placebo. Recently non-invasive Magnetic Resonance Imaging (MRI) techniques have been developed to assess small intestinal fluid distribution, transit and motility as well as colonic fluid, volumes and motility in healthy volunteers and constipated subjects. Other laxatives such as movecol and ispaghula have been investigated using this methodology. This study will use these novel techniques to further characterize bisacodyl's mode of action. This study is intended to assess the effect of a single-dose of bisacodyl on the gut motor function and its effect on water distribution within the small and large intestine in subjects with occasional constipation by MRI. It may allow better understanding of the relative importance of both the secretory and the prokinetic effect of bisacodyl. Since bisacodyl is often used by self-medicating people with constipation it is proposed to study subjects suffering from occasional constipation. As such subjects often take the drug intermittently it would be of interest to study both the acute response after single dose and the response after several days of treatment to see if this alters the response. The current study will be performed as a cross-over with 2-period and 2-treatment (bisacodyl/placebo), for assessing the effects over of a single-dose of 5mg bisacodyl. Evaluations will be performed after one single dose of bisacodyl or placebo in two different time periods, separated by a 2 week washout period between end of period 1 and start of period 2. The study will recruit individuals ≥18yrs from the general public who consider themselves as suffering from occasional constipation and who self-medicate with an occasional over-the counter (OTC) laxative, not more than once a week. Up to 18 adult healthy subjects will be recruited to ensure 10 evaluable subjects. An evaluable subject is defined as participant having the primary endpoint assessed (ascending colon T1 300, 375, and 450 minutes correctly evaluated) for the two periods of the crossover.

Other laxatives such as movecol and ispaghula have been investigated using this methodology. This study will use these novel techniques to further characterize bisacodyl's mode of action. This study is intended to assess the effect of multiple doses of bisacodyl on the gut motor function and its effect on water distribution within the small and large intestine in subjects with occasional constipation by MRI. It may allow better understanding of the relative importance of both the secretory and the prokinetic effect of bisacodyl.

Patients with Terminal Chronic Kidney Disease undergoing Peritoneal Dialysis (PD) often have pathophysiological factors that promote chronic constipation. It affects the quality of life of Patients undergoing PD in a much greater way than for hemodialysis patients because it causes complications, mechanical and infectious associated with the transmural migration of enteral bacteria, with an impact on patient morbidity and survival of the technique. In addition, it should be noted that PD patients often take potentially constipants treatments such as phosphorus chelators, calcium inhibitors, opiates, iron preparation and antidepressants. Taking these drugs decreases gastric acidity, which is associated with an increased prevalence of peritonitis. In this context, a significant lack of literature, specifically studying the risk factors for constipation in Terminal Chronic Kidney Disease patients treated with DP and the correlation with mechanical and infectious complications, is improvable.
This study is a randomised, parallel group, controlled trial, comparing the effects of fruit products as to their physiological, microbiologic and metabolomic effects on the gut, as well as their effects on the dietary intake and quality in healthy people with constipation.
Once the patients who are candidates to enter the study are identified, the patients will be randomly be assigned to two groups, according to the sequence: - Group A: study product+wash out+control product - Group B: control product+wash out+study product
The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.
To gain a better understanding of the underlying dysmotility in constipation in children, we will use a novel minimal invasive method called 3D Transit. We will examine four groups of children aged 7 to 17 years: healthy children, chronically constipated children (ROM IV criteria), children with neurofibromatosis type 1 and finally children receiving chemotherapy (vincristin) for acute lymphoblastic leukemia.
The aim of the study is to confirm the effectiveness of chicory-derived prebiotic inulin-type fructans on bowel function in young children.
Effective treatment for constipation is a real clinical challenge especially in patients with severe symptoms. Dietary measures (bulking agents) and drugs (laxatives, stool softeners, suppositories and enemas etc.) have limited efficacy in severe cases. If conservative measures do not help, surgical therapies might be considered. Subsequently, antegrade enemas through percutaneous colonic catheter were introduced as a less invasive option for treating severe constipation. The cecostomy has been performed laparoscopically, percutaneously, and with the laparoscopic-assisted percutaneous endoscopic cecostomy (LAPEC) technique. This approach allows patients to deliver osmotic agents to the right colon.The procedure has been demonstrated to be safe and effective in young adults and pediatrics. To date, there are only few studies evaluating the safety and efficacy of the LAPEC procedure in adults and all have retrospective profile. The aim of this prospective study is to compare short and long-term efficacy and safety of LAPEC in patients with severe constipation. Symptoms of defecation will be the main outcome criteria.
Researchers are trying to better understand why constipation occurs and improve the tests for diagnosing these conditions.
