Each individual will become adopted up for his or her medical data for at least 1? yr or till the end of study period (up to 4?years). Blood and stool samples will VX-765 cell signaling become collected VX-765 cell signaling sequentially during the 1st yr of biological treatment. Intestinal cells will become sampled after 1?yhearing of treatment and whenever an endoscopy is performed. Samples will undergo transcriptomic, proteomic and microbial DNA analyses. Omics data will become integrated with medical data to identify a panel of predictive biomarkers of response to biological therapy and disease behaviour in individuals with IBD. Ethics and dissemination Honest approval has been from the Danish Ethics Committee (H-18064178). Inclusion is definitely ongoing at three study centres and will be initiated in two additional centres. Both positive and negative study results will become disseminated through peer-reviewed journals according to Conditioning the Reporting of Observational Studies in Epidemiology recommendations, as well as offered at international conferences. of this study are to Identify microbial, proteomic and transcriptomic predictors of treatment results to biological therapy in biological-na?ve individuals with IBD. Identify microbial, proteomic and transcriptomic biomarkers of disease progression and degenerative features of IBD. are to Investigate treatment results for biological treatment in biological-na?ve individuals with IBD inside a real-life setting. Evaluate adherence to national and international recommendations concerning initiation, follow-up and optimisation of biological therapy. Methods Study design This study is definitely a multicentre, prospective cohort study that may investigate microbial, proteomic and transcriptomic predictors of treatment results to biological therapy in VX-765 cell signaling biological-naive individuals with IBD. Patient enrolment was initiated in May 2019 and is currently ongoing at four study centres, two additional study centres will initiate enrolment in medio 2020. Enrolment will continue until May 2022. The duration of follow-up of each individual will become at least 1?yhearing from initiation of biological therapy or until May 2023. Clinical data and biological samples will become collected at each study check out during the 1st yr. Study appointments are scheduled prior to initiation of biological therapy and consequently at routine appointments for the administration of biological therapy in the outpatient medical center after 0, 2 and 6 weeks of treatment, and consequently every second or third month. After the 1st year, medical data will become updated at least every 6?months until the end of follow-up (number 1). Open in a separate window Number 1 Study design of the Danish IBD Biobank Project. Patient and general public involvement Patients were not involved in the process of refining the research question or the design of this study. In the future, the study aims at involving the Danish patient organisation for individuals with IBD (Colitis and Crohns Association) in the design of future studies which may arise from the current study. Establishing The Danish IBD Biobank Project is a collaboration between the departments of gastroenterology at six private hospitals including five university or college hospitals located in four out of five geographic areas in Denmark. VX-765 cell signaling These include the departments of gastroenterology at Hvidovre University or college Hospital, Herlev University or college Hospital, Aarhus University or college Hospital, Tnfrsf1b Aalborg University or college Hospital, Odense University or college Hospital and the Hospital of Soenderjylland. Individuals will become recruited from your outpatient medical center or when they are admitted to the hospital prior to the initiation of biological therapy. Apart from the included departments, the study seeks to increase the collaboration with additional Danish private hospitals in the future. Study population Individuals are eligible for inclusion if they are (1) diagnosed with IBD (UC, CD and IBDU) according to the Copenhagen diagnostic criteria,25 (2) aged 18 or above and (3) starting treatment with biological therapy due to IBD and have by no means received treatment with biological providers previously. Initiation of biological treatment is definitely a medical decision made by the individuals physician. Individuals will receive biological therapy according to the recommendations and recommendations from your Danish Medicines Council, which include dosing and treatment intervals according to the drug labels. All participating private hospitals are advised.
