Objectives: Dysbiosis of the gut microbiota (GM) is observed in both murine models and humans with cystic fibrosis (CF). Laxative treatments are typically used to improve gastric motility and alleviate gastrointestinal symptoms associated with CF. Genistein, a phytochemical in soy, exerts therapeutic benefits by activating intestinal CFTR ion channels but whether genistein affects the GM in CF is unknown. This study aimed to establish whether dietary genistein alters the GM community structure in a murine model of the most common CF-associated mutation, DF508...

Genistein is a naturally occurring isoflavone found in soy. Genistein has been shown to increase the open probability of the most common cystic fibrosis (CF) disease-associated mutation, ∆F508-CFTR. Mice homozygous for the ∆F508 mutation are characterized with severe intestinal disease and require constant laxative treatment for survival. This pathology mimics the intestinal obstruction (meconium ileus) seen in some cystic fibrosis patients. This study tested whether dietary supplementation with genistein would reduce the dependence of the ∆F508 CF mouse model on laxatives for survival, thereby improving mortality rates...

BACKGROUND/AIMS: Low-volume polyethylene glycol (PEG) bowel preparations are better tolerated by patients than high-volume preparations and may achieve similar preparation quality. However, there is little data comparing their effects on a recommendation for an early repeat colonoscopy (because of a suboptimal preparation), procedure times, adenoma detection rate (ADR), and advanced adenoma detection rate (AADR). METHODS: This is a retrospective cohort study of outpatient colonoscopies performed during a one-year period at a single academic medical center in which low-volume MoviPrep® (n = 1841) or high-volume Colyte® (n = 1337) was used...

Polyethylene glycols (PEGs) are believed to be chemically inert agents, but larger PEG polymers could have immunogenicity. A 39-year-old man was referred to emergency room for loss of consciousness and dyspnea after taking of PEG-3350 (Colyte®). In laboratory findings, the initial serum tryptase level was increased to 91.9 mg/L (normal range: 0.00-11.40 mg/L) without any other laboratory abnormalities. The intradermal test with 10 mg/mL Colyte® showed a 5 × 5 mm wheal, but basophil activation and histamine releasability tests were negative...

BACKGROUND: Poor preparation for elective colonoscopy is common in persons with spinal cord injury (SCI). This unsatisfactory outcome is likely due to long-standing difficulty with evacuation and decreased colonic motility. Our objective was to determine the most effective preparation for elective colonoscopy applying a novel and traditional approach to bowel cleansing. METHODS: Twenty-four subjects with SCI were consented and scheduled to receive one of the two possible arms: pulsed irrigation enhanced evacuation (PIEE) or polyethylene glycol-electrolyte lavage solution (PEG; CoLyte(®))...

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) transmission route is not yet clearly understood. Isolating H. pylori from stool, saliva, and vomitus is very difficult. However, H. pylori could be cultured from feces in the setting of rapid gastrointestinal tract transit. The aim of this study was to isolate H. pylori by culture and PCR in the rectum and terminal ileum during colonoscopy. METHODS: Twenty subjects with positive UBT (urea breath test) were included...

It is unclear how polyethylene glycol (PEG) laxatives compare with other classes of laxative in terms of efficacy. To assess efficacy of PEG vs. placebo and active comparators in adults with non-organic constipation. Text Word searches were carried out on MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Clinical Trials and Google Scholar databases covering the period January 1970 to October 2009. Search terms were (constipation) AND (randomised OR randomized) AND (PEG OR polyethylene OR macrogol OR movicol OR idrolax OR miralax OR transipeg OR forlax OR colyte OR golytely OR isocolan OR nulytely) NOT colonoscopy...

As part of an ongoing performance evaluation and Quality Improvement (QI) program at the U. S. National Naval Medical Center in Bethesda, Maryland, two bowel preparations that were concurrently in use (Fleet Phospho-soda and Colyte/Dulcolax) were evaluated for patient tolerance and preference, efficacy, and cost. Anonymous patient questionnaires were distributed during a three-phase assessment that took place over an 18-month period. This approach identified preconceived ideas regarding bowel preparations and contributed to development of objective information regarding the bowel preparations currently available...

Patients undergoing colonoscopy who have poor bowel cleansing must undergo repeated colon lavage and procedure, resulting in the possibility of additional discomfort and risk. Patient compliance with the necessary 4 liters of colon lavage fluid is essential. At our facility, the current colon lavage solution is unflavored and most patients complain about the taste. These are the patients who are likely to have poorly cleansed bowels. Patient preference for flavor of lavage is not known. A randomized controlled trial of 130 patients was undertaken to learn whether Colyte flavor made a difference in bowel cleansing...

Severe constipation caused by colonic inertia may be associated with a generalized gastrointestinal dysmotility syndrome. Patients with severe constipation pose a significant challenge in terms of management. Failure of medical therapy usually leads to surgery in the form of a subtotal colectomy. Most patients develop diarrhea after the surgery, but a subgroup of patients continue to experience constipation. We report the case of such a patient who underwent a total abdominal colectomy and ileorectostomy for intractable constipation...

BACKGROUND: Currently available aqueous purgatives used before colonoscopy are poorly tolerated. We designed a tableted sodium phosphate purge that we believe will yield much greater patient acceptance. METHODS: A total of 305 outpatients undergoing routine diagnostic colonoscopy were randomized to one of three preparation groups: Colyte (100 patients), Fleet Phospho-Soda (106 patients), or sodium phosphate tablets (99 patients). Endoscopists were blinded to the type of preparation administered and answered a questionnaire regarding preparation quality...

OBJECTIVE: To evaluate the effect of gut gavage both alone and with enteral administration of monoclonal antibodies to endotoxin on the liberation of tumor necrosis factor (TNF)-alpha and subsequent hemodynamics after hemorrhage/resuscitation. DESIGN: Dose response intervention, sham-controlled animal study. SETTING: Research laboratory at a university medical center. ANIMALS: Instrumented rats (250-325 g body weight) underwent standardized hemorrhage/resuscitation...

Mouse models of cystic fibrosis that are generated by targeted disruption (knockout) of the cystic fibrosis transmembrane conductance regulator gene, cftr(-/-), typically die shortly after weaning, from intestinal obstruction/rupture caused by an inability to secrete fluid into the bowel lumen. We investigated the use of a commercial osmotic laxative, Colyte, provided continuously in the drinking water, to increase the survival of cftr(-/-) mice. Genotype analysis of 623 offspring surviving at 10 days of age yielded 28...

BACKGROUND: Many patients dislike the taste and saltiness of polyethylene glycol-electrolyte colonic lavage solutions. Several commercially available lavage solutions have been introduced with reduced salt content or flavouring added in an attempt to improve palatability and to encourage patient compliance. AIM: To determine which of the commercially available lavage solutions are the most palatable. METHODS: A taste test of the five commercially available lavage solutions was performed by two groups of subjects: (a) adult patients scheduled to undergo colonoscopy (n = 50) and (b) adult family members of patients scheduled to undergo colonoscopy and hospital volunteers (n = 50)...

A review of the relevant English-language literature on bowel cleansing before colonoscopy yielded results of randomized trials comparing a variety of regimens, including polyethylene glycol (PEG)-electrolyte lavage, 3-day clear liquid diet with laxatives or prokinetics, and oral sodium phosphate, as well as these regimens combined with agents such as metoclopramide, cisapride, and senna. Balancing the importance of such factors as cleansing effectiveness, safety, ease of completion, side effects, patient tolerance, and cost, the authors recommend four methods: (1) PEG-electrolyte solution (eg, CoLyte, GoLYTELY, NuLytely) in combination with senna (eg, X-Prep), (2) PEG-electrolyte solution alone (either single dose or split dose), (3) oral sodium phosphate (Fleets Phosphosoda) given in split dose, and (4) oral magnesium citrate in combination with rectal pulsed irrigation...

Many patients dislike the taste of the oral gastrointestinal lavage solutions utilized prior to colonoscopy. Specifically, patients dislike the salty taste and the quantity of the polyethylene glycol-electrolyte solution that they are required to ingest. In an attempt to reduce the salty taste and potentially improve patient compliance and tolerance of the preparation, flavoring was added to the lavage solution. Fifty-six patients received standard or flavored polyethylene glycol-electrolyte lavage solution in random order prior to colonoscopy...

The purpose of this study was to evaluate whole gut lavage with polyethylene glycol electrolyte solution (Colyte), as a potentially adjunctive measure in lowering serum acetaminophen levels. The effect of bowel lavage was evaluated on serial serum acetaminophen concentrations after 2-g and 4-g doses in 7 and 12 male patients, respectively. Mean peak level of serum acetaminophen after 2 g (60 min after intake) was not significantly lowered by bowel lavage. After 4 g, peak acetaminophen serum levels were significantly lower after bowel lavage (65...

Faecal impaction with or without encopresis is a very common problem. We performed a randomized, open-label, prospective study to compare the efficacy and acceptability of the treatment of faecal impaction using either mineral oil or pineapple-flavoured isotonic intestinal lavage solution containing polyethylene glycol-3350 (Colyte). Thirty-six patients over 2 years of age were randomized to receive either mineral oil or flavoured lavage solution. The dose of mineral oil was 2 to 8 tablespoons twice a day for two days (17 patients--Group I) and of lavage solution was 20 ml/kg/h for 4 hours on two consecutive days (19 patients--Group II)...
