33 Clinical Trials for Constipation
The purpose of this study is to characterize the intestinal flora in subjects with systemic sclerosis-related constipation and/or significant bloating and to determine safety and trends in improvements in the diversity of colonic microbiome and patient symptoms following the administration of either frozen or lyophilized PRIM-DJ2727 microbiota.
Tenapanor is the newest FDA-approved drug for IBS with constipation (IBS-C). This study seeks to understand tenapanor as a treatment for cystic fibrosis-related constipation (CFrC) in CF patients. Participants will ingest one 50 mg tablet of tenapanor, twice daily, for a 4-week treatment period. They will also complete three questionnaires, the PAC-SYM, PAC-QoL, and IBS-SSS, and daily diaries to characterize GI symptom burden and spontaneous bowel movement (SBM) frequency.
Investigation of tenapanor as a potential treatment for synucleinopathy-associated constipation
Constipation is one of the most prevalent gastrointestinal disorders in patients with chronic kidney disease (CKD) and has been associated with their adverse kidney and cardiovascular outcomes; however, little is known about the effects of constipation treatment on clinical outcomes nor on outcome-related biochemical and microbiological parameters in patients with CKD. The investigators aim to test the feasibility of delivering an intervention with constipation treatment and determine its effects on changes in clinical, biochemical, and microbiological parameters in patients with CKD and constipation.
The purpose of this study is to determine whether transcutaneous electrical acustimulation (TEA) alters systemic sclerosis (SSc)-related colonic and anorectal physiology by enhancing autonomic nervous system (ANS) function. The study will examine the effects of TEA on slow colonic transit (SCT) and rectal hyposensitivity (RH), to examine whether TEA improves autonomic dysfunction and modulates inflammatory pathways.
Constipation is a common and debilitating non-motor symptom of Parkinson disease (PD) that often precedes the onset of classic motor symptoms by decades. There is no standardized algorithm for managing constipation in this patient population, nor are there dedicated treatments. Studies suggest that constipation can affect quality of life to a significant degree, in many cases just as much as motor symptoms. There is an unmet need for effective treatment options for constipation in this patient population. The goal of this study is to determine the efficacy and safety of pyridostigmine as a treatment for chronic constipation in patients with PD.
Transcutaneous electrical acupoint stimulation (TEAS) is an emerging technology for non-invasive neuromodulation that has broad potential implications and warrants further study. The investigators' clinical experience from the University of California, Los Angeles (UCLA) Center for East-West Medicine (CEWM) has also demonstrated that TEAS can be used as an effective self-care tool for patients with chronic illness who do not have the time or resources for frequent acupuncture treatments. Chronic constipation is the chosen area of study because of the large population with a substantial impairment in health-related quality of life and work productivity. The investigators have recently completed a randomized controlled trial (RCT) demonstrating the benefit of perineal self-acupressure on quality of life measurements in this population, which supports investigation into other acupuncture-based self-care interventions. Given these findings, the investigators hypothesize that home patient-administered TEAS can provide measurable improvements in both symptom severity and health related quality of life.
Constipation is a very common problem. Western style toilets that are nearly universal in the United States require the person to sit on the toilet. However, results from uncontrolled studies suggests that a squatting posture (as prevalent in many foreign countries) may be better at facilitating evacuation compared to a Western style commode. One uncontrolled, unpublished study suggests that a footstool improved bowel symptoms in nearly 98% of 153 constipated participants. Hence, the investigators propose to evaluate the benefits of a footstool on symptoms and anorectal functions in constipated patients. Hypothesis: the regular squatting assist device (7 inches) but not a sham device (2 inches tall) will improve symptoms of constipation.
The aim of this pilot study is to investigate the effect of Osteopathic Manipulative Medicine (OMM) in decreasing constipation symptoms in people with Parkinson's disease (PD). A second but optional aim is to determine if OMM changes the bacterial flora of the mouth and gut. OMM is a safe and gentle manual treatment provided by osteopathic physicians. All participants will receive OMM during the second half of the eleven week trial.
The aim of this study is to better understand how tenapanor affects the metagenomics and metabolomics of patients with irritable bowel syndrome with constipation (IBS-C). Tenapanor is the newest FDA-approved agent for IBS-C. It is a small molecule that inhibits the NHE3 receptor, leading to impaired sodium and water absorption in the intestine. Previous clinical trials comparing tenapanor to placebo showed that a 50 mg dose of tenapanor led to increased bowel movements and decreased abdominal pain. This study consists of an 8-week treatment period in which subjects will ingest one capsule of tenapanor (50 mg per dose), twice daily, and send in stool samples following 4 weeks and 8 weeks of treatment.
Prucalopride is a medicine used to treat constipation. The main aim of the study is to measure prucalopride concentrations in breast milk. Other aims are to check the growth and development of babies breastfed by their mothers who took prucalopride and to check if the babies had any side effects. During the study, participants will provide one set of milk samples over 24 hours using an electric breast pump. Breast milk samples will be collected at home and will be shipped to the laboratory. Also, participants will be asked questions during telephone interviews every 2 months in the first year of their baby's life. They will also be asked to complete growth and development questionnaires about their baby.
The research objective is to characterize the risk of a major adverse cardiovascular event (MACE) among new users of naldemedine versus new users of lubiprostone and new users of naloxegol as comparator opioid induced constipation (OIC) medications.
Consecutive patients with Irritable Bowel Syndrome with Constipation (IBS-C) will be recruited from the outpatient clinics of the University of Michigan Health System. Eligible patients will be asked to participate in a study that will test the efficacy the PEG 3350 + a diet low in fermentable oligo, di, monosaccharides, and polyols (FODMAP) vs. PEG 3350 plus sham diet. Blinding dietary advice trials is challenging and therefore the sham diet was based on the criteria set forth by Staudacher et al. which emphasizes that the diet must give the impression that is the true intervention diet with similar restrictions, modifications, and time intensity without impacting the intake of essential nutrients, fiber, and FODMAPs. An example of the sham diet's carbohydrates includes: apples, bananas, and pears, and wheat. Oranges, raspberries, strawberries and rice would not be allowed. Additionally, the physicians analyzing the data will be blinded as to which group the patients were randomized.
This study of the efficacy and safety of Plecanatide in children 6 to \<18 Years of Age with Irritable Bowel Syndrome with Constipation (IBS-C)
The overall objective of this study is to determine the effect of posterior tibial nerve stimulation (PTNS) on children with constipation due to pelvic floor dyssynergia. Our main hypothesis is that PTNS effectively treats children with constipation secondary to pelvic floor dyssynergia through modulation of anorectal function. We will perform a single-center, randomized controlled pilot study comparing PTNS to sham stimulation in children with constipation secondary to pelvic floor dyssynergia.
Project is a trial, in which women undergoing vaginal surgery for pelvic organ prolapse will be randomized 1:1 to a postoperative bowel regimen of either oral senna or rectal bisacodyl suppository.
The goal of this clinical trial is to test the use of a laxative before surgery in women having surgery to fix pelvic prolapse that do not have constipation. The main question it aims to answer is: Does use of a laxative before surgery lessen the discomfort of bowel movements after surgery? Participants will be asked to complete questionnaires before and after surgery. Researchers will compare using the laxative before and after surgery versus only after surgery to see if there is less discomfort with bowel movements after surgery.
This study will evaluate changes in the fecal microbiome in constipated pediatric patients before and after antegrade continence enema placement and initiation of antegrade enema flushes. Subjects will have their microbiome sequenced prior to placement by obtaining a fecal sample. Pre-antegrade continence enema placement results will be compared to fecal samples obtained at 0, 4, 8 months after placement of the antegrade continence enema and initiation of miralax or golytely flushes to look for changes in bacterial diversity.
This study will assess the efficacy of two active treatments with TEA and a chemical neuromodulator (escitalopram aka Lexapro) versus a sham comparator or control group on abdominal pain.
Postoperative constipation affects up to a third of women undergoing minimally invasive (MIS) gynecologic surgery and is a major source of anxiety and discomfort. The average time to first bowel movement after gynecologic surgery is about 2 to 4 days and some factors responsible for this include anesthesia inhibitory effect on gastrointestinal motility, opioid pain medication use, chronic NSAID use and anatomic manipulation. There are no established regimens to manage postoperative constipation after minimally invasive gynecologic surgery. Two studies evaluating the implementation of postoperative bowel regimen with polyethylene glycol (PEG) and with Senna and Docusate found no significant impact on postoperative bowel function. There have been no studies looking at the effect of preoperative bowel regimens on postoperative bowel function. The purpose of this study is to evaluate postoperative bowel function after minimally invasive hysterectomy in women receiving a preoperative 10-day bowel regimen of PEG daily.
Researchers are trying to better understand why constipation occurs and improve the tests for diagnosing these conditions.
This is a randomized, double-blind, placebo-controlled dose-ranging study to assess the safety and efficacy of tenapanor for treatment of the IBS-C in pediatric patients 6 to less than 12 year old.
The purpose of this study is to determine if adult patients with IBS-C will report an overall greater improvement in IBS symptoms and quality of life when treated with a combination of linaclotide (standard of care medication) and immersive virtual reality (VR) therapy compared to those treated with linaclotide and sham (placebo) VR therapy.
This is a randomized, double-blind, placebo-controlled study to assess the efficacy, safety and tolerability of tenapanor (25 mg and 50 mg) in pediatric patients (≥12 and \<18 years old) with IBS-C when administered twice daily (BID) for 12 consecutive weeks.
This study collects information on pregnant women with ongoing constipation who took prucalopride and those who did not take prucalopride. The main aim of the study is to learn if any medical problems in pregnant women or their infants might be related to taking prucalopride during pregnancy. Participants are not required to take prucalopride during the study. The study is non-interventional. Women and their infants are followed during pregnancy and for 1 year after pregnancy to collect information on maternal, pregnancy, and infant outcomes. During the study, participants will be asked questions during 3 telephone interviews; 2 during pregnancy and 1 just after their expected delivery date. Participants who took or are taking prucalopride will be asked more detailed questions about this during these interviews. All information is collected remotely, and no visits to the study site are required. Also, all participants will be asked to complete a questionnaire about their baby when their baby is about 1 year old.
Persons with spinal cord injury (SCI) have neurogenic bowel disorders which is associated with significant morbidity. The negative impact of bowel complications is often at the top of the list of problems reported by persons with SCI. Despite the magnitude of the problem of bowel dysfunction in persons with SCI, and the associated reduction in quality of life, this condition has yet to be effectively treated. The investigators have developed a novel dual drug combination to elicit a safe and predictable bowel evacuation (BE). The ability to move the bowel contents along to the rectum was severely impaired primary because of poor gut contractions on the left side of the colon, as shown by our team of investigators. To address this problem, a dual medication combination (neostigmine and glycopyrrolate) was developed that safely and predictably caused the bowel to empty after delivering these drugs into a vein (intravenously) or into the muscle bed (intramuscularly). Because no one likes needles, and because of the practical limits of administering medications on a routine basis by the use of needles, especially in persons with SCI because of their other health considerations, the investigators have devised a new approach: driving these medications across the skin and into the circulation of the body by applying an electrical current that is too small to feel (iontophoresis). The proposed research project to determine the safety of positively charged compounds (e.g., vitamin B12, NEO, and GLY) administered transcutaneously by the prototype wireless ION device and to compare the pharmacokinetic profiles of transcutaneous administration of NEO and GLY by the wireless ION device to a commercially available wired ION device. The potential administration of any number of other positively charged agents by this wireless prototype may be a clinically relevant outcome of this work. The ability to use a wireless ION device is far more practical for patients to use, especially those with SCI, which will permit the self-administration of these agents in the home setting to induce a bowel evacuation.
Constipation affects 12-19% of Americans. Pelvic floor dyssynergia is considered to play an important role in constipation but the underlying mechanisms are not well understood in individual patients. The investigators have developed a novel device named Fecobionics that provide detailed mapping of physiological parameters during defecation. The aim of the study is to use Fecobionics to assess anorectal function in dyssynergia patients and monitor and predict the outcome of the biofeedback therapy.
Minimally-invasive surgery, either laparoscopic or robotic, is commonly used in urology. Several urologic procedures including prostatectomy, radical nephrectomy, and partial nephrectomy are now commonly performed robotically. Patients undergoing these procedures often have delayed return of bowel function and persistent gastrointestinal symptoms including nausea/vomiting, abdominal distension, and bloating for several days to weeks after surgery. Postoperative stool softeners and laxatives are routinely used in an effort to minimize these symptoms, with varying degrees of success. The aim of this study will be to evaluate whether the use of a preoperative osmotic laxative will be beneficial in improving recovery of bowel function and alleviating postoperative gastrointestinal complaints in patients undergoing these procedures. Patients will be randomized to either receive or not receive three days of polyethylene glycol (PEG, also known as MiraLAX) on the three days before surgery. Patients in both groups will receive the same postoperative bowel regimen including scheduled PEG both in the hospital and upon discharge until first bowel movement. Patients will be given a questionnaire and diary to record their postoperative gastrointestinal symptoms and time to first bowel movement. These questionnaires and diaries will then be analyzed to determine differences in time to first bowel movement and gastrointestinal complaints during their recovery from surgery.
Develop a registry (list of patients) with accurate clinical motility diagnosis. This registry will help the doctors to identify the patients with specific disease conditions. It will also help in promoting future research in gastroenterology motility disorders
The goal of this study is to evaluate whether polyethylene glycol 3350 (PEG3350) versus senna is better at relieving postoperative constipation after urogynecologic surgery. The main questions it aims to answer are: What number of patients taking PEG3350 have obstructed defecation syndrome (ODS), a form of constipation, vs those taking senna in the week after urogynecologic surgery? What patient-level and procedure-level characteristics are associated with postoperative ODS, in patients taking PEG3350 vs senna? participants will: Take their randomized medication daily for seven days after surgery Fill out an ODS questionnaire before and one week after surgery Complete a daily bowel diary for 7 days after surgery
