The aim of this study was to assess time trends in diagnostic delay, therapeutic approaches, arterial lesion accrual, persistent disease activity and remission rates in TAK. Methods The study cohort included all 78 patients from the 1999???2012 population-based South-East Norway TAK cohort and 19 patients from a tertiary referral cohort. TAK was classified by the 1990 American College of Rheumatology criteria and/or the 1995 altered Ishikawa diagnostic criteria. Data were retrieved by review of electronic patient journals and imaging data analyses. Results Diagnostic delay fell significantly during the study period and the number of lesions at diagnoses fell from three to two. Patients diagnosed from 2000 onwards more often received up-front treatment with disease-modifying antirheumatic drugs (DMARDs) than those diagnosed before 2000 (51% vs 4%; test or Mann-Whitney test and the proportions were compared by the chi-square test or Fishers exact test as appropriate. A value 0.05 was considered significant. Results Characteristics of the study cohort The study cohort included 97 patients with TAK. The population and referral cohorts were comparable in age, gender and ethnicity (Table?1). Altogether, 392 MRI and 108 CT angiography examinations, 245 ultrasound examinations of the neck arteries and 198 PET-CT examinations were available for analysis, and the patients had a median of 10 disease-related visits at Oslo University Hospital during the observation period. The median number of imaging studies available for each patient in the early versus late cohorts, respectively, were; MRI angiography (3 versus 4), CT angiography (1 vs 1), Ultrasound of neck arteries (1 vs 3) and PET-CT (1 vs 2).

Methods The study cohort included all 78 patients through the 1999???2012 population-based South-East Norway TAK cohort and 19 individuals from a tertiary referral cohort. TAK was categorized from the 1990 American University of Rheumatology requirements and/or the 1995 customized Ishikawa diagnostic requirements. Data had been retrieved by overview of digital patient publications and imaging data analyses. Outcomes Diagnostic delay dropped significantly through the research period and the amount of lesions at diagnoses dropped from three to two.
