BACKGROUND: @entity1897 is a well-recognised complication of @entity29 ( @entity29 ). Little is known of its natural history, but a variety of joint involvement has been described, from large joint pauciarticular @entity2720 to a @entity309 pattern polyarthropathy. AIMS: To classify the peripheral @entity2720 according to pattern of articular involvement, and study their natural history and clinical associations. METHODS: The case notes of all @entity1 attending the @entity29 clinic were reviewed, and information on general disease characteristics, extraintestinal features, and @entity2720 extracted. This was confirmed by direct @entity1 interview using questionnaires at routine follow up. @entity1 with recorded joint swelling or effusion were classified as type 1 (pauciarticular) if less than five joints were involved and type 2 (polyarticular) if five or more were involved. @entity1 without evidence of swelling were classified as @entity4841 . RESULTS: In total, 976 @entity1 with @entity31 ( @entity31 ) and 483 with @entity30 ( @entity30 ) were reviewed. Type 1 occurred in 3.6% of @entity1 with @entity31 (83% acute and self-limiting) and in 6.0% of those with @entity30 (79% self-limiting); 83% and 76%, respectively, were associated with relapsing @entity29 . Type 2 occurred in 2.5% of @entity1 with @entity31 and 4.0% of those with @entity30 ; 87% and 89%, respectively, caused persistent symptoms whereas only 29% and 42%, respectively, were associated with relapsing @entity29 . CONCLUSION: @entity1897 without axial involvement can be subdivided into a pauciarticular, @entity2720 , and a bilateral symmetrical polyarthropathy, each being distinguished by its articular distribution and natural history.
