The purpose of this study is to evaluate the clinical effectiveness (how well the treatment works) of Guselkumab, by lines of treatment and subpopulations, and what are the outcomes of treatment (clinical outcomes) in adult participants with moderately to severely active Ulcerative Colitis (UC) or Crohn's Disease (CD) under real-world settings. CD and UC are the main type of Inflammatory bowel disease, a group of inflammatory conditions of the colon and small intestine.

A Study to Generate Real-world Evidence of Guselkumab Effectiveness in Inflammatory Bowel Disease in Germany

The purpose of this study is to characterize participants with Crohn's Disease (CD) and Ulcerative Colitis (UC) treated with Guselkumab in a real-world setting, and to assess the clinical effectiveness (how well the treatment works) in the overall population and in different participant subgroups. Furthermore patient-reported outcomes like fatigue, health-related quality of life (HRQoL), sexuality, work productivity and activity as well as treatment satisfaction will be assessed.

Longitudinal Immunophenotyping of Patients With Inflammatory Bowel Disease

Background: Inflammatory bowel disease (IBD) is a term used to describe disorders that cause long-term inflammation in the digestive tract. Symptoms include stomach pain, diarrhea, and bleeding. Crohn's disease and ulcerative colitis are the 2 main types of IBD. Researchers want to conduct a natural history study to learn more about whether genetic factors can cause IBD; how immune cells contribute to IBD; and how diet, drugs, and disease affect those cells. Objective: To better understand IBD over time. Eligibility: Adults aged 18 to 85 years with Crohn's disease, ulcerative colitis, or another IBD. Their healthy relatives are also needed. Design: Affected participants will have clinic visits every 6 months for 3 years. Once a year, they will have these procedures: A physical exam with blood and stool samples. Ultrasound of the abdomen. A wand will be rolled over the skin. It uses sound waves to capture images of the intestines. Magnetic resonance imaging (MRI) scan. They will lie on a table that slides into a tube. Magnetic fields will capture images of the intestines. Colonoscopy. A long, flexible tube with a video camera will be inserted into the rectum to view the entire colon. Up to 12 tissue samples may be taken. Upper endoscopy, for those with Crohn's disease. A long, thin tube with a camera will be inserted through the mouth and into the first part of the small intestine. Up to 12 small tissue samples may be taken. Questionnaires. Participants will answer questions about their disease and their diet. Midyear visits will include a physical exam, blood and stool collection, ultrasound, and questionnaires Healthy relatives will have 1 blood draw for genetic tests.

A Randomized Crossover Trial of Bright Light Therapy in Crohn's Disease on Intestinal Barrier Homeostasis

Crohn's Disease (CD) and Ulcerative Colitis (UC), collectively known as inflammatory bowel disease (IBD), are two of the most significant chronic conditions of the gastrointestinal tract (GIT) and affects over 1.5 million individuals in the U.S. Recently, there has been an increased understanding of the importance of sleep and sleep disruption in IBD as a potentially modifiable risk factor. We, therefore, hypothesize that intervening with morning bright light therapy (BLT) in IBD patients with CM will decrease intestinal permeability and pro-inflammatory cytokines, positively impact intestinal microbiota, and improve quality of life (QoL).

Research on the Use of Probiotics in the Prevention and Treatment of Inflammatory Bowel Disease

This study evaluates oral Lactobacillus reuteri as an adjunct therapy for 2 months. Endoscopic assessments will be performed at baseline and after 2 months of intervention to evaluate intestinal inflammation. Intestinal fluid samples will be collected during endoscopy for 16S rRNA gene sequencing to assess changes in the gut microbiota. Peripheral blood inflammatory markers and fecal calprotectin levels will also be measured to evaluate changes in intestinal inflammation.

COVID-19 Booster and IIV Schedule in Immunocompromised Hosts

The goal of this pragmatic embedded open-label, 2 x 2 factorial phase II randomized controlled trial is to evaluate strategies to improve COVID-19 booster and influenza vaccine immunogenicity in people living with immunocompromising conditions (PLIC). The main questions it aims to answer are: 1. Is co-administration of seasonal inactivated influenza vaccine (IIV) with the most up-to-date recommended COVID-19 booster dose non-inferior in inducing a 1-month peak protective humoral response against COVID-19, compared to a strategy of sequential administration of COVID-19 booster dose followed by seasonal IIV given one month later? 2. Is the administration of the most up-to-date recommended COVID-19 booster doses at 3-month intervals superior at maintaining a longer term protective humoral immune response, compared to booster doses administered at 6-month intervals? Researchers will compare (1) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 3-month interval, (2) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 3-month interval, (3) COVID-19 and Influenza vaccines administered at Day 0 + COVID-19 Booster at a 6-month interval, and (4) COVID-19 vaccine administered at Day 0 and Influenza vaccine administered at Day 28 + COVID-19 Booster at a 6-month interval to see if median neutralization capacity of patient sera is non-inferior in the co- vs. sequential administration arms at 1-month after the initial COVID-19 booster and superior in the 3-month interval arms vs. the 6-month interval arms at 12 months after the initial COVID-19 booster. These outcomes will also be compared at 2-months for question 1 and 6-months for question 2. People living with immunocompromising conditions who take part in the trial will have blood samples drawn to verify immune response, be monitored for changes in clinical events and therapies, and complete questionnaires to verify adverse effects, quality of life and economic impact.

Immune Regulation in Ulcerative Colitis or Crohn s Disease

This study will investigate in patients with Crohn s disease and ulcerative colitis how the body s immune system controls inflammation in the gastrointestinal tract (stomach and intestines)-specifically, how lymphocytes (a type of white blood cell) function in inflammatory responses. This protocol does not involve any experimental treatments. Patients between the ages of 0 and 75 years of age with Crohn s disease or ulcerative colitis or symptoms of inflammatory bowel disease may be eligible for this study. Screening tests may include the following: medical history and physical examination, routine blood tests, examination of stool specimens, X-rays such as barium enema or upper GI series, proctosigmoidoscopy, colonoscopy, gastroduodenoscopy, and small bowel biopsy. Participants will receive medical treatment according to the best generally accepted measures for treating Crohn s disease or ulcerative colitis. This may include anti-inflammatory drugs, immunosuppressive drugs, and antibiotics to treat infections. A surgical consultation may be recommended for patients whose disease does not respond to medical treatment. If surgery to remove intestinal tissue is recommended, a qualified gastrointestinal surgeon will perform the procedure. In addition, participants may undergo the following procedures: * Blood drawing - No more than 450 milliliters (30 tablespoons, or 15 ounces) of blood will be taken from adults over a 6-week period. A maximum of 7 ml (1/2 tablespoon) of blood per kilogram (2.2. pounds) of body weight will be obtained from children within the same time period, with no more than 3 ml/kg taken at any one time. * Leukapheresis - This procedure is done to collect large quantities of white blood cells. Whole blood is collected through a needle in an arm vein, similar to donating blood. The blood is circulated through a machine that separates it into its components, and the white cells are removed. The rest of the blood is returned to the body, either through the same needle or through another needle in the other arm. * Intestinal biopsies - Intestinal tissue will be obtained during colonoscopy with intestinal biopsy in patients who require this procedure as part of their standard medical care. Patients are given a sedative to reduce anxiety, but are conscious during the procedure. A flexible tube is inserted into the rectum and large intestine, allowing the physician to see the intestinal mucosa. At various places, small pieces of tissue are plucked out.

Whey Protein Milk-Derived Exosomes

This Phase 1B open-label, uncontrolled multicenter trial evaluates the safety, tolerability, and potential efficacy of WPMDE2, a whey protein milk-derived exosome supplement, in adult patients with mild to severe ulcerative colitis (UC). The study aims to explore clinical improvements in disease activity, quality of life, and inflammatory markers over an 8-week intervention period with a 2-week follow-up. WPMDE2 is administered orally in two dosage groups, with 100 participants stratified by disease severity. Key endpoints include changes in disease severity, fecal calprotectin levels, and patient-reported outcomes. Conducted under ethical guidelines, the study seeks to establish WPMDE2 as a safe, naturally derived adjunct therapy for UC patients.

Impact of Morning Light Therapy in IBD

The pilot study will focus on the effects of morning light therapy (MLT) in adult patients with ulcerative colitis (UC) who have evidence of poor sleep quality and active inflammation. The specific population is at risk for circadian rhythm sleep-wake disorders and has significant potential benefit from circadian realignment, which may lead to improved sleep quality and, ultimately, UC-related inflammatory activity. During an initial one-week lead-in period, participants will obtain baseline circadian-related labs, complete symptom-related surveys, and use a wearable device continuously to obtain baseline sleep-wake data. After the lead-in week, patients will undergo one hour of MLT while wearing wearable devices continuously and completing daily symptom surveys. At the end of four weeks of MLT, patients will obtain post-intervention circadian and inflammatory assessments in addition to completing the same symptom-related surveys.

Investigating Serotonin Signalling in IBD Patients

Alterations in normal serotonin (5-hydroxytryptamine;5-HT) signaling have been reported in ulcerative colitis (UC) and Crohn's disease (CD). Studies report an increase in enterochromaffin (EC) cell, main source of 5-HT in the gut, numbers in CD and UC patients. Up-regulated expression of mucosal Tryptophan hydroxylase (TPH)-1, catalytic enzyme in 5-HT production, messenger RNA (mRNA) have been found in CD patients in remission who are suffering the irritable bowel syndrome (IBS)-like symptoms. Alterations in normal 5-HT signaling has also been reported in animal models of inflammatory bowel disease (IBD). Thus, the aim of the proposed research project will be to study the alterations in 5-HT signalling accompanying GI inflammatory conditions, such as IBD.

Testing an Immunotherapy Anti-cancer Drug, Nivolumab, for Advanced Cancers in Patients With Autoimmune Disorders, AIM-NIVO

This phase Ib trial studies the side effects of nivolumab and to see how well it works alone and in combination with other treatments, such as ipilimumab, cabozantinib, platinum containing therapy, and fluoropyrimidine, in treating patients with autoimmune disorders and cancer that has spread from where it first started (primary site) to nearby tissue, lymph nodes, or distant parts of the body (advanced), to other places in the body (metastatic) or cannot removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib blocks certain proteins, which may help keep tumor cells from growing. It may also prevent the growth of new blood vessels that tumors need to grow. Cabozantinib is a type of tyrosine kinase inhibitor and a type of angiogenesis inhibitor. Chemotherapy drugs, such as platinum containing therapies and fluoropyrimidine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab alone and in combination with other treatments, including ipilimumab, cabozantinib, platinum containing therapy, or fluoropyrimidine, may be safe, tolerable, and/or effective in treating patients with autoimmune disorders and advanced, metastatic, or unresectable cancer.

Early Changes in Inflammatory Indices and Healing in IBD

This prospective observational study aims to evaluate early changes in blood-based inflammatory indices during the first 4 weeks after treatment initiation or escalation and their relation to endoscopic and histological healing at 12 to 16 weeks in adult patients with inflammatory bowel disease.

The EDICT Trial - Therapy for Inflammatory Bowel Disease Flares

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), are chronic inflammatory conditions of the gastrointestinal tract that affect millions of people in the United States of America. Among patients with IBD, symptomatic flares are quite common; up to 40-50% of patients in some populations report having a flare at least once per month. For most patients with IBD flares, the typical outpatient treatment consists of corticosteroids and, in some instances, initiation of or switching between 5-aminosalicylic acid-acid preparations, immunomodulators, or biologics. These treatments, while often effective, can have harmful side effects, especially when used for long durations of time. Therefore, alternative treatments are highly sought after by both patients and providers.

Fecal Microbiota Transplantation for Ulcerative Colitis Using Dai and Han Donors

This study is a randomized clinical trial evaluating fecal microbiota transplantation (FMT) for ulcerative colitis (UC) using healthy donors from two ethnic groups in Yunnan, China. UC is a chronic inflammatory bowel disease causing colon inflammation and ulcers. FMT transfers gut bacteria from a healthy donor to a patient to restore healthy intestinal microbiota. Previous research suggested that FMT using donors from the Dai ethnic group (a minority nationality in Yunnan with special dietary habits) may achieve better results than Han Chinese donors for UC. This study aims to confirm this finding and understand why. The investigators will recruit 200 UC patients (ages 18-60) and randomly assign them to two groups (100 each). One group will receive FMT from healthy Han donors; the other from healthy Dai donors. Patients will receive three FMT infusions via endoscopic intestinal tubing. Treatment effects will be assessed at 12 weeks using clinical scores (Mayo score), endoscopic scores (MES), inflammatory markers (fecal calprotectin, CRP, ESR), and intestinal barrier function tests. Stool samples will also be analyzed using metabolomics and metagenomics to identify key gut bacteria and metabolites linked to better outcomes, and laboratory experiments will be performed to verify how they reduce intestinal inflammation. The goal is to identify optimal donor characteristics for FMT in UC and uncover mechanisms that may lead to more personalized microbiota therapies.

The aim of this study is to determine the effect of medication use and disease activity on the outcome of pregnancy among women with IBD up to 18 years from birth.

ENhanced Recovery in CHildren Undergoing Surgery

The institution of perioperative Enhanced Recovery Protocols (ERPs) has been found to decrease hospital length of stay, in-hospital costs, and complications among adult surgical populations but data in pediatric populations are lacking. The Assessing Effectiveness and Implementation of a Perioperative Enhanced Recovery Protocol for Children Undergoing Gastrointestinal Surgery, which has the short title "ENhanced Recovery In CHildren Undergoing Surgery (ENRICH-US)," study is a multicenter, pragmatic, prospective study, using a stepped wedge cluster randomized controlled trial design. The study is designed to test the adoption, effectiveness, and generalizability of a newly developed, 21-element ERP for children undergoing elective gastrointestinal surgery.

Effects of Relaxation Response Mind-body Intervention in Patients With IBS and IBD

In this pilot study, the investigators examined whether a relaxation response mind-body intervention could be effectively delivered to mixed groups of IBS and IBD patients and determined the effects of the intervention on quality of life, inflammatory markers, and gene expression using transcriptional profiling.

Study of the Role of Soluble Inhibitor of Interleukin 22, Interleukin 22 Binding Protein (IL-22BP), in Chronic Inflammatory Bowel Disease

IL-22 is an IL-10 family cytokine that plays major actions to increase intestinal epithelial barrier function and regeneration during experimental colitis. IL-22 binding protein is a small, soluble, and secreted protein potently inhibiting IL-22 actions through preventing the binding with IL-22 Recepteur. This study aims at characterizing how IL-22 binding protein is regulated in Inflammatory bowel disease to better understand the way IL-22 acts on epithelial cells during flares of the disease.

A Study to Assess Real-world Outcomes for Long-Term Use of Guselkumab

The purpose of this study is to evaluate how long guselkumab remains in participants with moderate to severe crohn's disease (CD) or ulcerative colitis (UC) in real-world setting. CD and UC are Inflammatory bowel disease, a group of inflammatory conditions of the colon and small intestine.

Testing of an Educational Tool for Patients With Melanoma and Pre-Existing Autoimmune Disease Who Are Candidates for Immune Checkpoint Inhibitors

This study learn how easily patients can use an educational tool that will be created for patients with melanoma and pre-existing autoimmune diseases who receive or will receive immune checkpoint inhibitor drugs. Patients will be asked their opinions about the design, accessibility, and content of the tool. Researchers will use the information collected to improve the educational materials that will help patients make future decisions about their treatment.

Physical Activity and Bone Mineral Density in Children and Adolescents With Chronic Inflammatory Bowel Disease

This study is an observational study. The purpose of this study is to assess the relationship between bone health and daily physical activity in children and adolescents with inflammatory bowel disease (IBD). Reduced bone mineral density is a common complication in pediatric IBD. Physical activity is an important determinant of health throughout the whole lifespan. Engaging in regular moderate-to-vigorous physical activity has important health benefits. Based on available evidence, the investigators hypothesize that daily moderate-to-vigorous physical activity could improve bone health (ie bone mineral density) in children and adolescents with IBD.
