Early diagnosis of inflammatory bowel diseases in patients with spondyloarthritis

Abstract

Seronegative spondyloarthritis (SpA) (psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA)), inflammatory bowel disease (IBD) and psoriasis form a group of immunoinflammatory diseases (IIDs). The increased risk of developing IBD in patients with IIDs is known and, on the contrary, the risk of skeletal-muscle IIDs in patients with IBD was demonstrated. This indicates the necessity of early diagnosis of IBD in patients with SpA. In connection with this, a screening tool «Universal questionnaire for identifying signs of immunoinflammatory diseases» was developed and put into practice. The article shows the results of the «Universal questionnaire for IIDs» use in rheumatology practice by 140 patients with SpA. It was found that 17.2% patients with PsA and 20.8% with AxSpA required further exclusion of IBD. The need to exclude IBD was equally frequent in patients with PsA and AxSpA. Clinical and laboratory parameters in groups with the alleged IBD did not significantly differ from those in other patients, which confirms the need to introduce the «Universal questionnaire» into the practice for the purpose of early diagnosis of combined IIDs.
