A new research report published recently has evaluated the role of Magnetic Resonance Enterography (MRE) amongst children having spondyloarthritis.
Spondyloarthritis is a group of many types of inflammatory arthritic conditions including arthritis associated with inflammatory bowel disease (IBD). Spondyloarthritis generally attacks the spine and in some cases, the joints of arms and legs.
AdvertisementMagnetic Resonance Enterography is commonly used to diagnose and monitor Inflammatory Bowel Disease (IBD). It is the preferred choice over Computed Tomography for evaluation of IBD as it is a non-invasive, radiation free interrogation. Although colonoscopy is usually used in the final diagnosis and detecting changes in IBD, the cost involved is high.
This is one of the first studies to evaluate the role of MRE in studying the changes in gut inflammation amongst children with spondyloarthritis.
In this small pilot study, five children, four with spondyloarthritis and one with juvenile idiopathic arthritis were identified for sub-clinical inflammatory bowel disease diagnosed using the fecal test.
Three children were identified with signs of IBD. The findings included -
• thickening and uptake of contrast agent at the distal end of the small intestine in one child;
• uptake of the contrast medium in the distal end of the small intestine and no thickening in the second child; and
• prominent vasa recta (intestinal arteries) and mesenteric lymph nodes (lymph nodes that lie between the lining of the abdominal cavity connecting the duodenum and small intestine to the back wall of the abdomen) in the third child.
Colonoscopy was conducted in the case showing changes in the distal end of the small intestine which confirmed inflammatory bowel disease.
The researchers found that the use of MRE amongst children with sub-clinical inflammatory bowel disease was well-tolerated and practical. It shows the possibility of the use of this test to screen sub-clinical bowel disease.
