Adjunctive Treatment With Vitamin D3 in Patients With Active IBD

Inflammatory bowel disease ((IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC)), is a chronic, immune-mediated disease characterized by recurrent episodes of relapse. The incidence of IBD is increasing worldwide and poses as a burden that reduces quality of life and has a significant impact on health care resources. The advent of monoclonal antibodies to tumor necrosis factor-? (anti-TNF) has revolutionized treatment of IBD, improving rates of remission and reducing hospitalizations and surgeries. Nevertheless, many patients do not adequately respond to these therapies or lose response over time. Thus, there is an important need for novel immunomodulating agents to improve our ability to achieve remission. Besides its traditional role in bone homeostasis, several studies have recognized the important role Vitamin D plays in modulating the immune response, cancer, and cardiovascular disease. Specifically, Vitamin D may mediate immunity by modulating autophagy in leukocytes and regulating the gut microbiome. Thus, Vitamin D may play an important role in IBD. Furthermore, evidence suggests that the effect of vitamin D may be mediated through the TNF-? pathway, suggesting a synergy with anti-TNF therapy. This is a randomized, double blind, placebo-controlled trial to study the effect of Vitamin D3 as an adjunct therapy for patients with active CD, UC, or IBD unspecified who are undergoing anti-TNF induction therapy.

Postoperative Extended Venous Thromboprophylaxis in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) is a relatively common disease that effects all age groups and carries significant morbidity and mortality. The initial treatment typically involves both short and long term medication, however when this is not enough to adequately control the disease, surgery is often required. The high morbidity and mortality rates are in part due to the increased rates of venous thromboembolism (VTE) such as deep vein thrombosis (DVT) or pulmonary embolism (PE) which have been shown to develop more frequently in IBD patients compared to the general population. Undergoing abdominal surgery has also been shown to independently increase rates of DVT and PE and since the majority of patients with IBD will undergo surgery at least once in their lifetime, the relative increased risk of developing a VTE is very high. The majority of DVT and PE events in the postoperative IBD population will occur after discharge from hospital and therefore carries significant morbidity and mortality risk in a unmonitored setting. Several studies have demonstrated the benefits and safety of twice daily dosing of oral extended VTE prophylaxis agents in orthopedic and cancer postoperative patients following discharge from hospital. There have been no randomized studies which have evaluated the use of extended postoperative VTE prophylaxis in IBD patients. The purpose of this randomized placebo controlled pilot trial will be to evaluate the efficacy and safety of postoperative VTE prophylaxis in IBD patients following abdominal surgery. If this pilot trial demonstrates efficacy in reducing postoperative DVT and PE rates, safety and feasibility, clinicians will be armed with the knowledge to pursue a larger multicenter randomized trial with the intent of reducing overall morbidity and mortality in this high risk population.

Effect of a Probiotic Mixture on the Gut Microbiome and Fatigue in Patients With Quiescent Inflammatory Bowel Disease

The study is proposed as a single-site randomized double-blind placebo-controlled trial requiring 4 study visits, where two of the visits are combined with their appointment for routine clinical care. The study population will consist of patients with quiescent CD and UC and IBD-unspecified recruited from the Massachusetts General Hospital Crohn's and Colitis center. All eligible subjects will have a confirmed diagnosis of CD, UC, or IBD-unspecified according to accepted clinical, endoscopic, radiologic, and histologic criteria. Eligible patients will be contacted at the time of their routinely scheduled office visit and consented for the study. Self-report and review of medical records will be used to obtain detailed information regarding their disease on an intake questionnaire completed by a research study coordinator. The study is proposed as a 12-week double-blind randomized controlled trial of the probiotic supplement compared to placebo. We propose to examine the effect of a specific probiotic supplement on the changes in the gut microbiome, serum metabolomic profile, and fatigue symptoms in patients with quiescent IBD. Within 2 weeks of screening, eligible patients will be invited to visit MGH for a baseline visit. The patient will receive either the probiotic supplement or placebo for 4 weeks. The first follow up visit will be at week 4 to check for adverse events on study treatment, to check accountability of probiotics/placebo, and to complete the set of questionnaires. Also, subjects will receive probiotic/placebo samples for the remaining 8 weeks of treatment. At week 8, subjects will receive a phone call from a study research coordinator to check in with probiotics/placebo intake for treatment compliance and accountability records, and to complete the set of questionnaires ascertaining subjective symptoms. Last study visit will be at week 12 which is often combined with a regular office appointment. Subject will provide serum blood and stool sample, as well as complete the set of questionnaires.

Cost Effectiveness of an Intervention in Hospitalized Patients With Disease-related Malnutrition

Objectives: To evaluate the effectiveness, and cost-effectiveness, of three hospitalized patient care strategies in relation to disease-related malnutrition (DRM) hospital admissions based on results such as length of stay of the index admission, and from admission until one year after admission, mortality rate, appearance of complications, changes in weight and nutritional state, changes in their health related quality of life and functional status, readmissions, use of health services resources (primary care, hospital and emergency consultations) and costs. Methodology: Intervention study involving three hospitals with three branches in which, after nutritional screening in all centers, the first branch / hospital includes a intervention strategy for nutritional improvement in patients who after screening are identified as having DRE or at risk of DRE, and follow-up of other patients; a second cohort / hospital will include similar patients in which if there is any nutritional intervention it will be carried out by demand of the medical staff in charge of the patient; and a third branch /hospital in which the usual practice of the center will be followed without any explicit intervention. Subjects of the study: At least 300 patients in each center admitted to the digestive services, due to digestive pathologies, and surgery services due to tumor and digestive system pathologies. In all patients, sociodemographic and clinical data will be collected and of the outcomes described above during admission and until the year of follow-up. Statistical analysis: through appropriate multiple regression models for each outcome variable and with adjustments through propensity scores to compare the three centers based on each outcome parameter. A cost-effectiveness analysis will be carried out through of the incremental cost for each year of quality-adjusted life (QALY) .
