Plain English summary of protocol

Background and study aims.
Inflammatory bowel disease can sometimes be associated with a form of arthritis known as axial spondyloarthritis. This arthritis causes inflammation of the spine resulting in back pain, stiffness and reduced range of movement. AxSpA is often diagnosed late because it is a relatively uncommon cause of back pain and there are many other causes of back pain which may be considered by your doctor first. It is, however, important to make this diagnosis as early as possible in order to receive the most effective treatment. This study is designed to find out how many people with IBD [who have previously had an abnormal CT scan] also have axSpA. This knowledge will increase awareness of axSpA in IBD, and may suggest an alternative identification route for such patients. This aims to reduce the time to diagnosis and enable earlier access to available treatments.

Who can participate?
Adult patients with pre-existing IBD (CD or UC), with a previous CT scan highly suggestive of axSpA, as identified by the radiology team at the Norfolk and Norwich University Hospital (NNUH).

What does the study involve?
Patients with a known diagnosis of IBD who had a previous CT scan for their bowel disease and in whom there are imaging features highly suggestive of axSpA. These patients will have been identified via a service evaluation review undertaken by the radiology department. Patients will be invited to participate in the study via a postal questionnaire. If patients are deemed eligible, they will be invited to attend an assessment in the Rheumatology Department consisting of a medical interview, physical examination, blood tests, and an MRI scan of the spine and pelvis.

What are the possible risks and benefits of participating?
Participants will have an opportunity to find an explanation for their back pain. If they are found to have inflammation in their spine or other potentially treatable causes of back pain, we will recommend that their GP refer them to the main rheumatology clinic and they may be given some different treatment to help manage their symptoms.

What are the possible risks of participating?
The new diagnosis of axSpA may have implications for the participants' day-to-day life (as being diagnosed with any chronic disease would), however as this will offer an opportunity to start treatment, this is likely to outweigh any distress caused.
There are some risks and discomfort associated with the study procedures outlined below:
•Blood collection: For most people, needle punctures for blood withdrawal do not cause any problems. However, sometimes they may cause bleeding, bruising, discomfort, infections, and/or pain where the skin is punctured. They may also feel dizzy.
•MRI: The risks associated with having an MRI of the spine and pelvis are very minimal. Participants who are claustrophobic (have a fear of closed spaces) or have had any metal placed in your body (for example, during surgery) may not be able to have the investigation.
As with any test, there is always a possibility that the results of the above investigations may identify another cause for one’s symptoms that may be unrelated to the study. This information will be forwarded to the participant and their general practitioner who will decide on their further care.

Where is the study run from?
Norfolk and Norwich University Hospital (NNUH) in the United Kingdom

When is the study starting and how long is it expected to run for?
July 2019 to June 2020

Who is funding the study?
Pharmaceutical company AbbVie (the company only provides the funding to support the research, but has no influence on the design, conduct, management of the study. The company will not have access to any personal identifiable data)

Scientific titleWhat proportion of patients with Inflammatory Bowel Disease have Axial Spondyloarthritis – An imaging referral strategy utilising Computed Tomography defined Sacroiliitis [Norfolk - Axial SPa Ibd REferral Computed Tomography Strategy (N-ASPIRE CT Strategy)]
Study acronymN-ASPIRE CT Strategy
Study objectivesHow common is the diagnosis of axial spondyloarthritis (axSpA) is in patients with known inflammatory bowel disease (IBD) such as Crohn’s Disease and Ulcerative Colitis who have previously had an abnormal Computed Tomography (CT) scan?

Health condition(s) or problem(s) studiedAxial Spondyloarthritis / Ankylosing Spondylitis, Spondyloarthritis, Rheumatology
InterventionThis is being undertaken as part of good clinical practice. Patients with a diagnosis of IBD who underwent a CT scan, and in whom there are suspicious features of axSpA will be invited to participate in the study via a postal questionnaire. If patients are considered eligible, participants will then be invited to attend an assessment in the Rheumatology Department. This will comprise an expert medical interview, physical examination, blood tests and an MRI scan of the spine and pelvis.
Intervention typeOther
