Spondyloarthritides (SpA) and inflammatory bowel disease (IBD) are chronic, idiopathic inflammatory disorders of the axial and peripheral joints and the intestinal tract, respectively, affecting up to 1?% of the population. There is clinical and genetic evidence supporting some degree of overlap between the pathogenesis of these two entities. Nevertheless, their treatment is at times conflicting. NSAIDs, although useful in SpA, are considered to be possible risk factors for flares in IBD. Moreover, etanercept, a soluble TNF receptor blocker used in SpA, is ineffective in IBD. As patients with SpA often develop microscopic gut inflammation, it is important to understand the impact on disease progression or even therapeutic response. Further research is mandatory in this regard.
