BACKGROUND: @entity417 is a common manifestation of @entity29 ( @entity29 ), but its prevalence in the United States is not well defined. Aim of this study was to determine the prevalence and characteristics of @entity417 in @entity29 @entity1 who were followed in a US referral center. MATERIALS AND METHODS: Demographic, clinical, laboratory, and treatment data from a prospective, consented longitudinal @entity29 registry between the years 2009 and 2013 were analyzed. Disease activity was evaluated using Harvey-Bradshaw index in @entity30 ( @entity30 ) and @entity31 ( @entity31 ) activity index in @entity31 as well as @entity1851 and erythrocyte sedimentation rate. @entity417 was defined based on the World Health Organization criteria. RESULTS: A total of 1821 @entity29 @entity1 (1077 with @entity30 , 744 with @entity31 , median age 43.8 y, 51.9% female) were included. The 5-year period prevalence of @entity417 in @entity29 @entity1 was 50.1%, ( @entity30 : 53.3% vs. @entity31 : 44.7%, P=0.001). In multivariate logistic regression analysis, @entity417 was associated with surgery for @entity29 [odds ratio (OR)=2.77; 95% confidence interval (CI), 2.21-3.48; P<0.0001], female gender (OR=1.29; 95% CI, 1.04-1.61; P=0.02), @entity1851 (OR=1.26; 95% CI, 1.16-1.37; P<0.0001), erythrocyte sedimentation rate (OR=1.02; 95% CI, 1.01-1.03; P=0.0002), and use of biologics (OR=2.00; 95% CI, 1.58-2.52; P=0.0001) or immunomodulators (OR=1.51; 95% CI, 1.21-1.87; P=0.0003). @entity68 replacement therapy was administered to 46.8% of the anemic @entity1 . CONCLUSION: @entity417 has a high period prevalence in @entity29 @entity1 followed at a tertiary center. @entity417 is more common in @entity30 than in @entity31 , is associated with disease activity, and in current practice is undertreated.
