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.

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.

The main purpose of this study is to assess the amount of mirikizumab in breast milk in women who are breastfeeding who are receiving stable maintenance doses of mirikizumab for an approved indication. Participation in this study could last up to 94 days, including screening and follow-up period.

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.

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).

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.

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.

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.

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.

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.

This research study is addressing issues related to Inflammatory bowel disease (IBD), which is a chronic autoimmune disorder that affects over 60,000 Veterans. With close monitoring and timely treatment adjustment, the investigators can stop the natural progression of IBD, improving health-related quality of life (HRQOL) and reducing flares and hospitalizations. However, it is difficult to closely monitor Veterans with IBD between clinic visits. There is a critical need for solutions that support close between visit monitoring of Veterans with IBD. The Measurement-Based Care (MBC) for IBD study will take a systematic approach to collect, share, and act on patient reported outcome (PRO) data that can be used to achieve close monitoring. MBC supports patients' in managing their condition and boosting their confidence in their ability to handle their symptoms and disease, and also supports care teams in early recognition of health issues. The investigators will work with both Veterans and their care teams to understand and assess this program so it can be a model for future initiatives.

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.

The purpose of this study is to see how a diet that mimics fasting effects inflammation in patients with mild to moderate Ulcerative Colitis (UC). The diet may allow users to receive the benefits of fasting while also being able to enjoy food (the ingredients of which are GRAS (generally recognized as safe) by the Food and Drug Administration (FDA). Research on dietary interventions and UC are very limited. Fasting mimicking diets (FMD) have been studied with support of the National Institute of Health and published in leading journals. This research investigates whether markers of inflammation decrease and/or quality of life increases after three cycles of a five-day period of the fasting mimicking diet, and may provide rationale for its use to treat UC.

AMBU-VAX is a prospective, single-center observational study designed to develop and implement an organizational model for delivering recommended vaccinations within a hospital setting. The study targets adult and elderly patients with chronic diseases or immunocompromising conditions who are eligible for vaccination according to national immunization guidelines. Vaccination is actively proposed during outpatient visits, hospital admissions, or at discharge and, when accepted, administered within the hospital or coordinated with local public health vaccination services. The study aims to evaluate the feasibility, uptake, and completion of hospital-based vaccination pathways and to support integration between hospital and territorial prevention services for vulnerable populations.

Inflammatory bowel disease (IBD) is often comorbid with depressive disorder, and the development and progression of both conditions are closely related to the composition of gut microbiota and metabolites. However, studies investigating their comorbidity using microbiome and metabolomics approaches remain limited. This study aims to investigate the diversity changes in the gut microbiome and metabolome of patients with comorbid IBD and depressive disorder through multi-omics approaches, to identify specific microbial and metabolic signatures associated with the comorbidity of these two conditions, and to provide a molecular basis for elucidating the underlying mechanisms.

The PLANET Study aims to determine the impact of microplastics on intestinal inflammation and gut microbiome in order to understand the role of this pollutant on the risk of developing inflammatory bowel disease (IBD) as well as other diseases. With this information, the researchers hope to characterize better the role of environmental pollutants on IBD and develop novel strategies towards prevention.

The investigators will be evaluating bone marrow composition via magnetic resonance imaging in newly diagnosed adolescents with Crohn disease (CD) compared to healthy, matched controls. The investigators will also be assessing their bone mineral density via other imaging modalities, including dual-energy X-ray absorptiometry and peripheral quantitative computed tomography. This longitudinal project will focus on abnormalities in bone marrow composition, and specifically whether adolescents with newly diagnosed CD exhibit increased bone marrow fat, its association with bone mineral density (BMD) and the underlying pathophysiology, including bone turnover markers and immune cellular/molecular parameters.

A Multicenter National Prospective Study of Pregnancy and Neonatal Outcomes in Women with Inflammatory Bowel Disease study is being conducted at the University of California San Francisco and 30 other sites around the United States who are part of the CCFA Clinical Alliance. 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.

This study has been set up in order to characterize phenotypes and genotypes of patients with early onset enteropathies. In that goal, Investigators will collect biological samples (mainly blood) of patients suffering from early onset enteropathies and their healthy relatives.

This project involves the use of oral Lactobacillus reuteri as an adjunct therapy for 8 weeks. Endoscopic observation of intestinal inflammation will be conducted at 1 month, 3 months, 6 months, and 12 months after the administration of the drug. Intestinal fluid will be collected endoscopically for 16S RNA analysis to assess changes in the gut microbiota. Inflammatory changes in the patients will be detected through peripheral blood tests, and fecal calprotectin levels will be measured to evaluate the progression of the disease.

The investigators will be administering oral high dose interval vitamin D, concurrently when participants are receiving biologic therapy for their inflammatory bowel disease. The investigators will be collecting some additional bloodwork and questionnaires at the time of participants infusions.

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.

Inflammatory Bowel Disease (IBD), which encompasses ulcerative Colitis (UC) and Crohn's Disease (CD), has seen significant improvements in patient outcomes with biologic treatments. However, nearly half of the patients are either primary or secondary non-responders to the existing biologics. Upadacitinib is the only oral small molecule targeted drug approved for IBD in China. There is a paucity of research on the efficacy and safety of upadacitinib in treating Chinese patients with UC and CD, and a lack of study data on the Chinese IBD population. This study aims to conduct a multicenter, single-arm, prospective, observational real-world study to analyze the efficacy and safety of upadacitinib in the treatment of Chinese patients with IBD, providing a basis for clinical decision-making.
