Background Spndyloarthritis is a relatively common rheumatic disease with prevalences ranging from 0,31% to 1,9% in different populations and investigated with different methods.
Patients have inflammatory backpain or peripheral arthritis, enthesitis or dactylitis or both. New treatment possibilities with biologic agents and new imaging methods with MRI and Ultrasound has led to increased interest in diagnosis and assessment og these patients.
Objectives To study the prevalence of Spondyloarthritis and its subgroups in a region in Norway
Methods There has been a rheumatologic service at the hospital in Mo i Rana since 1994.Patients were recruited from the patient registry in the hospital in Mo i Rana, from primary physicians and physical therapists and from an ad in the local newspaper. Patients were assessed after ESSG-criteria, Clinical investigation including joint count and spinal mobility was done. BASDAI, BASFI and MHAQ was collected. X-ray and MRI of sacroiliacal joints were done in patient with inflammatory backpain. Patients 1st degree relatives older than 15 years of age were invited to the study and were sent a questionnaire which included questions about cronic synovitis or inflammatory backpain. Relatives with suspicious synovitis or inflammatory backpain in their history were invited to clinical investigation.
The rheumatology department in Bodø is 240 kms from Mo i Rana. Some rheumatic paients from Rana are followed i Bodø. The patient registry in Bodø was searched for patient with spondyloarthritis from the Rana area.
