Active clinical trials for "Inflammatory Bowel Diseases"

The purpose of this study is to measure IL-6 and IL-6/sIL-6R complex levels in subjects with active moderate to severe ulcerative colitis or Crohn's disease.

This multicenter study is being conducted to determine whether infliximab exposure after an initial infusion is predictive of early clinical response in hospitalized pediatric patients with severe steroid-refractory UC or IBD-U. This pilot and feasibility study will establish the infrastructure, demonstrate feasibility, and collect preliminary data to support the full study.

The purpose of this study is to determine the efficacy of SonoVue® in participants with Crohn's disease and ulcerative colitis to various aspects including type of Inflammatory Bowel Disease, disease activity, the need for surgical treatment.

Inflammatory bowel disease IBD, including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the intestinal tract with unknown etiology. The mechanism includes environment, genetics, intestinal microecology and immunity. In recent years, the incidence of IBD in Asian countries has continued to rise, and the incidence of CD and UC in Guangzhou has reached 1.09/10 million and 2.05/10 million respectively. The patient suffers from the disease for a long time, which greatly affects the mentality and the quality of life. However, the mentality and quality of life of IBD patients have not received the attention they deserve, and research in this area is relatively lacking. The study by Lewis et al. found that among IBD patients, up to 1/3 of depression patients and 2/3 of anxiety patients were not diagnosed in time. This study conducted an Internet questionnaire survey on IBD patients diagnosed in the Department of Gastroenterology, the Second Affiliated Hospital of Zhejiang University School of Medicine, to learn about the patients 'mental and psychological state, to screen the risk factors of patients'mental and psychological diseases, and to understand the impact of mental and psychological factors on the quality of life and quality of IBD patients. The impact of the disease provides a scientific basis for the optimal treatment of IBD.

Inflammatory bowel disease (IBD) has become a more prominent disease in the US population, with more than 3 million adults in the US affected. To manage this disease effectively, physicians tend to need to have a multidisciplinary approach as there are many psychosocial implications of chronic gastrointestinal illnesses like Crohn's and Ulcerative Colitis. Recent literature has supported the desire for telemedicine and remote physiologic monitoring for such patients to allow the patient to be more active in their treatments and make physicians more aware of what their bodies are doing from a physiologic perspective. Whoop is a new device founded in 2011 that has grown in popularity for its ability to accurately measure sleep patterns, resting heart rate, and heart rate variability (HRV) amongst other various physiologic measurements. Newer literature supports that depressed heart rate variability can correlate to disease flares such as heart failure exacerbations. The study investigators proposed that using remote physiologic monitoring in the IBD population along with their symptoms can help predict disease severity and potentially lead to earlier interventions if correlations are accurate. It can also spark interest in the younger generation for remote physiologic monitoring and telemedicine, which is believed to be beneficial in patients with chronic illnesses.

Syndecan-1 is a protein on the surface intestinal cells. previous studies proved low levels of mucosal syndecan-1 levels on the surface of intestinal cells is patients with acute and chronic inflammation due to inflammatory bowel disease. this protein might shed from cell surface to the serum. The investigators wish to prove that elevated serum levels of syndecan-1 may be predictive of disease presence, extent and severity, that buy taking a simple blood sample from patients diagnosed with inflammatory bowel disease and comparing to normal subjects and to other markers.

This is an observational cohort study with two time points (baseline and after at least 6 months of treatment with a non-corticosteroid immunosuppressive agent for inflammatory bowel disease (IBD)). Approximately 40 participants, both male and female, 18 years of age and older will be recruited from the Pittsburgh IBD Cohort. Participants will have a histological diagnosis of IBD (Ulcerative Colitis (UC) or Crohn's Disease (CD)) and will be attending for colonoscopy prior to starting a non-corticosteroid immunosuppressive agent as part of standard medical care. Immediately following the colonoscopy, an anal exam will be performed for research purposes to include: Perianal inspection Anal canal HPV swab Anal cytology Digital anal examination High resolution anoscopy (HRA) and biopsy of all lesions with visual criteria consistent with high-grade anal dysplasia For female participants a self- or clinician-taken vaginal swab for HPV typing. These procedures will be repeated at routine colonoscopy following at least 6 months but within 12 months of non-corticosteroid immunosuppressive treatment.

There is a reciprocal relationship between the central nervous system and the immune system. Stimulation of the vagus nerve results in secretion of acetylcholine (Ach) which decreases secretion of pro-inflammatory cytokines. Acetylcholine esterase is an enzyme that neutralizes Ach and thus, involves in regulation of Ach levels, and in the cholinergic tone and inflammatory state. MicroRNAs (miRs) are evolutionarily conserved, RNAs that regulate gene expression. The investigators hypothesized that miRs controlling systemic communication processes function in one tissue in response to signals (i.e. neuronal, hormonal or others) from another. Specifically, the investigators hypothesized that miRs control the inflammatory response in inflammatory bowel diseases through regulation of expression of messenger RNA of AchE.

The spread of Influenza H1N1 has prompted the development of vaccines against this virus. IBD patients are at increased risk of developing complications of Influenza H1N1. The efficacy and safety of H1N1 vaccination have not been evaluated in this population of patients. We would like to estimate the efficacy and safety of vaccination against influenza H1N1 in patients with IBD who treated with immunomodulatory drugs.

For the main goal - the accuracy of calprotectin for the diagnosis of IBD - calprotectin levels will be compared between patients with and without a diagnosis of IBD and the sensitivity, specificity and accuracy will be determined. For the secondary aim - the correlation between calprotectin levels and disease activity - in patients with IBD selected from this cohort, we will determine the association between calprotectin levels and clinical IBD score, serological markers (WBC, Hgb, Platelets, ESR, CRP, Albumin), endoscopic (disease score, pathological activity) and radiological features (bowel wall thickening, enhancement, edema, mesenteric inflammation).
