按位置、状态和其他条件筛选该研究列表。

1. Sustained Humoral and Cell-Mediated Immunogenicity of COVID-19 Vaccines in Patients With Inflammatory Bowel Disease

   Jacksonville, Fla.

   The purpose of this study is to determine the impact of systemic immunosuppression on sustained antibody COVID-19 concentrations in patients with inflammatory bowel disease (IBD) who received a COVID-19 vaccine.  This observational study will collect blood samples to measure sustained antibody concentrations to evaluate seroprevalence and study immunity  at 6 and 12 months after completion of vaccination.  The primary outcome of this study is to evaluate the immunogenicity of the Covid-19 vaccine in patients with IBD.

2. Sleep Health in Inflammatory Bowel Disease

   Jacksonville, Fla., Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The focus of the proposed study is to improve understanding of the underlying mechanisms of symptom burden, and the purpose is to describe how sleep health contributes to symptoms and functional performance in adults with Inflammatory Bowel Disease (IBD).

3. Virtual Reality for the Treatment of Abdominal Pain in Quiescent Crohn’s Disease

   Jacksonville, Fla.

   The purpose of the study is to evaluate the efficacy and safety of VR to treat abdominal pain in patients with quiescent Crohn's disease and assess the global and individual symptoms of Crohn's disease using validated instruments Patient Reported Outcomes Measurement Information System Pain scales, Hospital Anxiety and Depression Scale, Work Productivity and Activity Impairment, and Short Inflammatory bowel disease questionnaire.

    

4. Mayo Clinic Inflammatory Bowel Disease Repository

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this research study is to collect clinical information and human samples from patients with IBD. The data collected will be used to create an organized, accessible resource of human samples for biological research in IBD.

5. Adverse effects related to Heplisav-B vaccination in patients with Inflammatory Bowel Disease

   Jacksonville, Fla.

   In this study, we will examine the potential side effects experienced after receiving the new hepatitis B vaccine (Heplisav-B) in patients with ulcerative colitis or Crohn's disease. This new vaccine has been found to be more effective than the existing vaccine Engerix in people without ulcerative colitis or Crohn's disease. It is now the standard of practice vaccine that we use in the Mayo gastroenterology and liver practice. The most common side effects include pain, redness, swelling, fatigue, fever and headache. We would also like to determine if there was any worsening of the patient's underlying inflammatory bowel disease.

   Part 1

   Given these findings and recommendations, members of the Gastroenterology and Infectious Disease department feel that the Heplisav-B vaccine should be the preferred vaccine for patients with IBD and chronic liver disease. In this study, we aim to collect data on patients who receive this vaccine on whether they experience any adverse effects or any worsening of their bowel or liver disease. We also aim to collect data regarding the effectiveness of vaccination by measuring post-vaccination antibody titers at 1 month after vaccination. The goal of this is to confirm that patients have achieved immunity after vaccination. This is consistent with best-practice guidelines and CDC recommendations in immunosuppressed persons.

   Part 2:

   According to the 2022 Center for CDC guidelines for Hepatitis B vaccination in immunocompromised adults, persons found to have antibody titer concentration <10 mIU/ml (indicating non-immunity) after completion of a primary vaccine series should be revaccinated [6]. Accordingly, in the case of non-immunity after the standard 2-dose Heplisav-B series, we aim to give an additional dose of Heplisav-B and re-measure antibody titers at 1 month in order to evaluate effectiveness. This is consistent with best-practice and CDC guidelines in immunosuppressed patients that have not responded to the primary vaccination series. To this point, the CDC guidelines for Hepatitis B vaccination in immunocompromised adults state that a larger vaccine dose or additional vaccine doses may be necessary in this patient population [6]. Immunity to Hepatitis B through vaccination in patients with inflammatory bowel disease and chronic liver disease is crucial due to high risk of morbidity.

   Part 3:

   As a continuation of the above, we aim to perform immunological testing to observing T cell response to Heplisav-B vaccination. The goal is to measure if there are any differences in T cell response depending on certain immunosuppressive medications that the patient is taking for their IBD.

6. Utility Of Random Biopsies In Patients With Inflammatory Bowel Disease

   Jacksonville, Fla., Rochester, Minn.

   The proposed study is a multicenter parallel group clinical trial that will include 821 evaluable patients per group who will be randomly assigned to either high definition white light colonoscopy (HDWLC) with targeted biopsies plus 2 random biopsies in 4 segments to assess for inflammation (limited biopsy strategy) or HDWLC with targeted biopsies plus 4 biopsies every 10 cm throughout the colon, at a minimum in all segments of the colon known to have been affected by IBD at any time, regardless of the extent of disease (random biopsy strategy). Participants will be followed until total proctocolectomy or the end of the study period to determine whether the two methods of surveillance colonoscopy are associated with detection of dysplasia or sessile serrated adenoma at follow-up colonoscopy. Follow-up via chart review may continue for up to 15 years from enrollment.

7. A Study Of Vocal Biomarkers Of Disease Flares In IBD

   Jacksonville, Fla.

   The purpose of this study is to identify and evaluate a vocal signal capable of distinguishing active IBD flares from remission in patients with ulcerative colitis or Crohn’s disease using machine learning analysis of short voice recordings and to determine whether specific vocal patterns predict response versus non-response to medical therapy in this population.

8. A Study to Evaluate the Prevalence and Impact of Eating Disorders Among Patients with Inflammatory Bowel Disease

   Jacksonville, Fla.

   The purpose of this study is to assess the prevalence of eating disorders; specifically, Avoidant/Restrictive Food Intake Disorder (ARFID) among adult patients in the IBD clinic and compare to the patient population seen in the primary care clinics at Mayo Clinic Florida.

9. A Study Of Immune Transcriptomics And Gut Microbiome In IBD

   Jacksonville, Fla.

   The purpose of this study is to characterize B and T lymphocyte immune repertoire from blood and intestinal biopsies from patients with IBD.
