Filter by:Objective: The aim of this study is to investigate whether Crohn's Disease patients with peri-anal fistulas will suffer from sexual dysfunction in an attempt to help us identify Crohn's Disease patients that would benefit from sexual health interventions. Hypothesis: Crohn's patients with active perianal fistulas will have decreased sexual drive, performance, and satisfaction than those with Crohn's Disease in remission.
Background VSL#3 has been reported as an effective adjuvant therapy both in inducing and maintaining remission in pediatric patients affected by Ulcerative Colitis. In addition, it has been shown that VSL#3 is able to modulates barrier function, intestinal permeability, and innate host functions, which if altered, could have a profound impact on the state of colitis. However it is still unclear how VSL#3-induced changes in microbial composition affect the status of intestinal inflammation and no study have investigated the efficacy of VSL#3 in the maintenance of remission in pediatric patients with Crohn's disease (CD). Objectives The purpose of this study will be to evaluate the effect of a probiotic formulation, VSL#3, versus placebo, on metabolic profile, intestinal permeability, microbiota, cytokines and chemokines expression in pediatric patients with CD in remission of disease. In addition, the efficacy of VSL#3 on the maintenance of remission will be assessed and the safety and the tolerability of the probiotic formula will be evaluated. Methods This investigation will be a prospective, multicenter, randomized, double-blind, placebo-controlled, cross-over trial. The study will include 50 children affected by CD in remission of disease, as defined by a PCDAI < 10, under treatment with Azathioprine associated or not to 5-ASA and will be articulated in 6 months as follows. All children will be randomised to a treatment group receiving for 2 months either 1-2 packet containing 900 billion bacteria/day of VSL#3 according to their weight, and a group receiving the placebo drug. Assignment to therapy or placebo will be determined according to a computer-generated randomization scheme. At the completion of the 8 weeks, a "wash-out" period of 6 weeks will be done, when no preparation will be administered. Then each patient will be switched to the other group and followed likewise for further 8 weeks. All patients will continue regular medications throughout the study period. A group of 10 volunteer healthy children, comparable in age and sex, will be used as reference group for the analysis of metabolic profile. Patients will be assessed clinically at baseline and every 8 weeks until the completion of the study, at 24 weeks or at the time of relapse. At every visit data will be collected including patient questionnaires regarding disease activity (stool frequency, stool consistency, hematochezia, abdominal pain, extraintestinal manifestations of disease, and overall patient functioning). Additional information collected at the first visit included demographic data, family history, and symptom onset. Physical examination will be performed at each visit by a paediatrician and included an abdominal examination and examination for extraintestinal manifestations of CD. Routine blood tests for CD, cellobiose/mannitol small intestinal permeability study, stool cultures, stool calprotectin, will be performed at every visit and/or at the time of relapse. Urine will be collected for the analysis of metabolic profile with mono and bi-dimensional high-resolution 1H NMR spectroscopy. PCDAI and a physician's global assessment will be used to measure disease activity. At baseline and at 24 weeks the patients will undergo ileocolonoscopy to evaluate and endoscopic and histological activity of disease. Evaluation of microbiota on biopsies and stool samples will be performed at the time of ileocolonoscopies using Fluorescence In Situ Hybridization. Colon biopsies cultures will be performed in order to evaluate cytokines and chemokines patterns by multiplex assay. Additional data will be collected during the study regarding the safety and tolerability of therapy with VSL #3. Statistical analysis will be performed using SPSS version 15 (SPSS Inc, Chicago, Illinois, USA). Variables will be screened for their distribution and appropriate parametric or non parametric tests will be adopted as required. Cross-tabulations will be evaluated by using the Fisher test and χ2test. Statistical significance will be predetermined as P < 0.05. Expected results The investigators expect to find profound alterations in metabolic profiles, intestinal permeability, microbiota, cytokines and chemokine patterns of patients affected by CD. The administration of VSL#3 is expected to ameliorate all these alterations eventually identified. From a clinical point of view the effects of VSL#3 could be translated in prolonged clinical remission maintenance, offering a new therapeutic tool in the treatment of CD.
This is a prospective, multi-center (up to 6 sites) study which aims to To establish the effectiveness of the PillCam Platform with the PillCam Crohn's capsule as demonstrated by visualizing the small bowel and colon in patients with active symptoms associated with Crohn's disease (CD).
The objective of this study is to investigate the changes in crohn on resting energy expenditure.
This is an double-blind, single dose, four-period, crossover study in Japanese healthy male volunteers to assess the pharmacokinetics and safety/tolerability of single doses of GSK1605786A. Approximately 24 subjects will receive three treatments of 250, 500, and 1000mg GSK1605786 under fasted conditions or 500mg after food intake plus placebo in a dose ascending crossover design. Serial pharmacokinetic samples will be collected following each dose and safety assessments will be performed. The pharmacokinetics and dose proportionality of GSK1605786 after single oral doses of GSK1605786 at the dose levels of 250mg, 500mg and 1000 mg under fasted conditions will be assessed. In addition, a comparison will be made between the pharmacokinetics of GSK1605786 under fed and fasted conditions.
The purpose of this study is to evaluate effectiveness of 2 months antibiotic course of Azithromycin combined with Metronidazole compared with 2 months antibiotic course of Metronidazole alone.
This is an observational trial in Rheumatoid Arthritis and Crohn's Disease patients treated with Cimzia aiming to evaluate the risk and incidence of Tuberculosis.
This is a randomized, double-blind, placebo-controlled, multicenter, and proof of concept study with a parallel group design to evaluate the safety and efficacy of oral Trichuris Suis Ova (TSO) suspension, as compared to placebo, in patients with moderately to severely active Crohn's disease. This study will also have an optional open-label extension for patients completing the double-blind phase of the study.
The proposed study is designed to evaluate Pillcam regimen in Crohn's disease patients, using the PillCam Colon system.
The purpose of this study is to determine whether emotional processing and somatic dissociation influence IBS-like symptoms in Crohn's Disease patients.
