BACKGROUND AND AIMS: Inflammatory bowel disease [IBD] is a chronic disease which affects up to 0.5% of the population. Various extraintestinal manifestations occur, among which are rheumatic manifestations, grouped together under the name spondyloarthritis. The objective of this systematic review and meta-analysis was to give a systematic overview of the prevalence and incidence of spondyloarthritis in patients with inflammatory bowel disease. METHODS: We systematically searched Embase, Pubmed, OvidSP, Scopus, and Web-of-Science databases from inception to August 2016. All articles that addressed the prevalence or incidence of the different features of spondyloarthritis in adult inflammatory bowel disease patients were included. Methodological quality was assessed using a modified quality assessment tool developed for prevalence studies. RESULTS: A total of 71 studies were included, reporting on the prevalence of sacroiliitis, ankylosing spondylitis, arthritis, enthesitis, and dactylitis. Pooled prevalences were calculated for sacroiliitis (10%; 95% confidence interval [CI] 8-12%), ankylosing spondylitis [3%; 95% CI 2-4%], and arthritis [13%; 95% CI 12-15%]. Geographical area, setting and use of different criteria contribute to the large heterogeneity. Few estimates were available for enthesitis [prevalence range from 1% to 54%] and dactylitis [prevalence range from 0% to 6%]. Only three incidence studies were identified, which report cumulative incidences from 5 to 30 years. CONCLUSIONS: Spondyloarthritis occurs in up to 13% of patients with IBD. Ankylosing spondylitis is the least common [3%] followed by sacroiliitis [10%] and peripheral arthritis [13%].
