BACKGROUND: @entity1596 is reported to be the most common extra-articular manifestation in @entity1691 ( @entity1691 ); however, its prevalence and characteristics are not well established. OBJECTIVE: To perform a systematic literature review in order to examine these topics. METHODS: A systematic literature analysis was conducted in the Medline database up to October 2006 and in the abstracts of rheumatology scientific meetings for the years 2004, 2005 and 2006. A hand search of references was also performed. Articles were analysed if they reported the prevalence or characteristics of @entity1596 in @entity1691 . Data abstraction was standardised. Statistical analysis was mainly descriptive. RESULTS: Among the 957 articles selected by the search, 126 articles (29,877 @entity1 ) allowed a calculation of the prevalence of @entity1596 in @entity1691 ; 36 articles (1989 @entity1 ) described its characteristics. The mean (SD) prevalence of @entity1596 was 32.7 (0.5)%; it varied with the type of @entity1691 --for example, 33.2 (0.8)% for @entity1691 versus 25.1 (2.3)% for @entity5144 . This prevalence increased with mean disease duration and was higher in HLA-B27-positive @entity1 with an odds ratio of 4.2. @entity1596 was acute in 88.7 (2.5)%, anterior in 90.5 (2.0)%, unilateral in 87.3 (2.8)%. Recurrence occurred in 50.6 (2.6)% and a @entity227 was observed in 8.3 (3.8)%. CONCLUSION: The prevalence of @entity1596 varies with disease duration and according to the type of @entity1691 . Reduction of visual acuity is not exceptional. Because of recent promising data about the effects of anti- @entity5 necrosis factor therapy on @entity1596 flares in @entity1691 , it was important to determine this baseline prevalence.
