Safety and Efficacy of Fecal Microbiota Transplantation

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.

Effectiveness and Cost-effectiveness of Sacral Neuromodulation in Patients With Idiopathic Slow-transit Constipation

Rationale: Previous reviews showed that the evidence regarding the effectiveness of sacral neuromodulation (SNM) in patients with therapy-resistant, idiopathic (slow-transit) constipation is of suboptimal quality. Furthermore, there is no estimate of costs and cost-effectiveness in this patient group. Objective: The main objective of this study is to assess the effectiveness of SNM compared to personalized conservative treatment (PCT), in patients with idiopathic slow-transit constipation who are refractory to conservative treatment. The secondary objectives are assessing the 1) costs, 2) cost-effectiveness and 3) budget-impact of SNM compared to PCT. Hypothesis: Based on previous research we hypothesize that SNM will be more effective than PCT in terms of a significantly higher proportion of patients having treatment success at 6 months. Study design: An open-label pragmatic randomized controlled trial (RCT) combined with a prospective cohort study. Study population: Adolescent (14-17 years) and adult (18-80 years) patients with idiopathic slow-transit constipation refractory to conservative treatment. Intervention: The intervention is SNM, a minimally invasive surgical procedure consisting of two phases. In the screening phase an electrode is inserted near the third sacral nerve and connected to an external stimulator. If the screening phase is successful (average defecation frequency (DF) ?3 a week), the electrode is connected to a pacemaker that is implanted in the buttocks of the patient. If not successful, patients receive conservative treatment. The control intervention is PCT. This is the best and least invasive alternative to SNM. PCT consists of medication and/or retrograde colonic irrigation. Main study parameters/endpoints: The primary outcome is success at 6 months, defined as an average DF of ?3 a week according to a 3-week defecation diary. Secondary outcomes are straining, sense of incomplete evacuation, constipation severity, fatigue, constipation specific and generic (health-related) quality of life ((HR)QOL), and costs at 6 months. Furthermore, cost-effectiveness and budget-impact will be estimated.

Pelvic Floor Dysfunction and Its Influence on Body Image and Sexual Function

The first objective to determinate the prevalence of pelvic floor dysfunction in pregnant women and in the first year postpartum. The second objective is to assess the anatomical (both clinical and ultrasound), demographic and obstetric variables in symptomatic women and their association with pelvic floor dysfunction, sexual function and Body Image. This is a single center prospective cohort study. Women will be asked to fill out a questionnaire at the time of their 1st and 3rd trimester scan, at the postpartum checkup and 12 months postpartum. Furthermore, they will undergo a pelvic floor ultrasound at the time of their first and third trimester scan. The presence of pelvic floor dysfunctions will be recorded through validated self-administered questionnaires with five domains: Wexner questionnaire for anal incontinence, PAC-SYM for constipation, International Consultation on Incontinence Questionnaire Short Form for urinary incontinence, the Pelvic Organ Prolapse Distress Inventory for pelvic organ prolapse, POP/UI Sexual Questionnaire - IUGA revised for sexual function. The body image perception will be assessed using the Dutch-validated version of the self-administered Body Image Disturbance Questionnaire. The anatomy of the pelvic floor will be objectively assessed off line on 3D/4D transperineal ultrasound volumes and POP-Q examination. The demographic variables and information about the pregnancy and the delivery will be obtained from the medical records.
