Filter by:The main objective was to demonstrate the existence and importance of hypercoagulability in patients with IBD, by determining the prevalence of changes in coagulation parameters and evaluating the impact of these changes on the occurrence of thromboembolic events.
Inflammatory activities in the gastrointestinal tract are accompanied by an increase in blood flow in the intestinal wall layers of the respective organs. Also in chronic inflammatory bowel diseases, the release of vasoactive inflammatory mediators leads to vasodilation and consecutive increase of blood flow in the bowel wall. So far, these changes in blood flow can be detected by power Doppler sonography without being part of routine clinical diagnostics. Another promising option for non-invasive measurement of blood flow in the intestinal wall is Multispectral Optoacoustic Tomography (MSOT). Previous studies have shown that MSOT can be used to quantitatively measure hemoglobin in the bowel wall and thus provide information on blood flow and inflammatory activity in the intestines of patients with Crohn's disease. This is currently being further investigated in a pivotal study (Euphoria, H2020) and could lead to the possibility of non-invasive assessment of disease activity in inflammatory bowel disease (IBD) in the future. The regional blood flow in the intestinal wall and the distribution of gastrointestinal blood flow are also subject to strong postprandial changes. During absorption of food components, blood flow increases sequentially in the respective sections of the gastrointestinal tract, leading to postprandial hyperemia. Because postprandial hyperemia is particularly regulated locally by the presence of dietary components, there is a relationship between the sequential increase in blood flow in the intestinal wall and the peristaltic transport of chyme through the gastrointestinal tract. Postprandial hyperemia could also lead to an increase in the optoacoustic hemoglobin signal of the intestinal wall and thus have an impact on the assessment of inflammatory activity in IBD using MSOT. Additionally, MSOT allows the identification of non-absorbable exogenous chromophores, such as indocyanine green (ICG), which could allow co-localization of the chyme in the intestinal lumen after oral application of ICG. This pilot study investigates whether postprandial blood flow changes can be quantitatively measured using MSOT and whether these changes occur simultaneously with the gastrointestinal passage of the chyme as measured by the ICG signal in the intestinal lumen.
This clinical trial consists of two parts：1. a randomized, double-blind, single-center, placebo-controlled, dose-escalation PK study; 2. food effects and drug metabolism transformation study. The main purpose of this trial is to evaluate the Safety, Tolerance, Pharmacokinetics, Pharmacodynamics and Food effects of VC005 Tablets in healthy subjects.
People with inflammatory diseases are often treated with medications that act to suppress the immune-system, increasing the risk of catching infections. Consequently, vaccination with the pneumonia and seasonal flu vaccines is recommended for them. They were also prioritised to receive the COVID-19 vaccines early in the national rollout. However, the uptake of the pneumonia and seasonal flu vaccines among this group is lower than ideal. There may be many reasons why they do or do not seek to be vaccinated for these infections, such as the belief it may cause their disease to flare up or lack of knowledge of vaccines effectiveness. Anecdotally there was a high uptake of COVID-19 vaccines in adults with inflammatory conditions, however, concerns about vaccine-induced disease flare-ups and reports of complications deterred some from being vaccinated. A better understanding of why people do and do not seek vaccination may result in more targeted messaging for patients to help overcome vaccine hesitancy for these infectious diseases. This study aims to explore the drivers and barriers to being vaccinated among adults with common inflammatory conditions and on immune-suppressing medication. They will be invited to participate in a single, semi-structured interview. Interviews will be face-to-face, by telephone or video-call, last up to one hour, and digitally audio-recorded. They will explore participants' understanding of pneumonia, seasonal flu and COVID-19 and the risk they pose to their health, their understanding of vaccinations, beliefs of the benefits and risks of vaccinations for these infections, and reasons for seeking or not seeking vaccination. Findings will inform messaging about being vaccinated for these infections in patient education leaflets, such as those by patient charities regularly provided at speciality clinics. They will also be disseminated to healthcare professionals to help them better understand the drivers and barriers to vaccination.
This is a Phase 1, single-center, randomized, double-blind, third-party open (ie, participant blind, investigator blind and sponsor open), placebo controlled study to investigate PK, safety, tolerability, immunogenicity, and PD of PF 06480605 following a single subcutaneous dose of PF-06480605 450 mg and 150 mg (if needed) in Chinese healthy adult participants.
Phase angle (PhA) is a biometric parameter measured by bioimpedance analysis (BIA), which reflects organism cellularity and tissues hydration. In addition, since it correlates with the presence of inflammation and the nutritional status, it could be useful to monitor inflammatory bowel disease (IBD) activity. The aim of this study was to establish the potential use of PhA as a new non-invasive and sensitive marker correlated with mucosal healing and/or IBD activity.
The study series consists of three studies with the aim to assess the incidence, prevalence, risk factors, comorbidities and management of patients with alopecia areata in Czech Republic based on the patients and registry of a dermatology clinic of a metropolitan hospital.
Retrospective observational study in which the efficacy of infliximab is studied in patients with inflammatory bowel disease and its subcutaneous levels are monitored.
Chronic inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC) in historical cohorts. The pathways of oncogenesis of these CRCs, which are very different clinically from de novo CRCs, are currently unknown. The aim of our work is to identify specific molecular signatures of CRC occurring in the setting of IBD.
The LumenEye scope and CHiP platform will be piloted in a number of clinical settings including remote colorectal clinics. The rationale is to perform an initial pilot study to determine the clinical utility of the LumenEye device for use in primary and secondary care settings. The main hypothesis is that digital rectoscopy is safe and acceptable to clinicians including general practitioners and can significantly reduce the burden of endoscopy referral to and within secondary care centres.
