OBJECTIVE To characterize the epidemiology and clinical course of children with juvenile idiopathic arthritis-associated uveitis (JIA-U) in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry and explore differences between African American (AA) and non-Hispanic white (NHW) children. METHODS There were 4983 children with JIA(More)
OBJECTIVE There is wide variation in therapeutic approaches to systemic juvenile idiopathic arthritis (JIA) among North American rheumatologists. Understanding the comparative effectiveness of the diverse therapeutic options available for treatment of systemic JIA can result in better health outcomes. The Childhood Arthritis and Rheumatology Research(More)
BACKGROUND Studies of quality of life (QOL) in children with juvenile idiopathic arthritis (JIA) have focused on changes in musculoskeletal function secondary to arthritis. The role of visual functionality as a result of JIA-associated uveitis and its complications has not been examined. We evaluated the individual impact of physical and visual disability(More)
Juvenile idiopathic arthritis (JIA)-associated uveitis can be associated with vision-compromising complications such as cataracts, glaucoma, synechiae, and band keratopathy. Of these, cataracts are one of the most common sequelae of JIA-associated uveitis and can result in significant visual disability. Risk factors for cataracts include posterior synechiae(More)
OBJECTIVE Rheumatoid factor-positive polyarthritis (RF+ poly) is the juvenile idiopathic arthritis (JIA) category that resembles adult seropositive rheumatoid arthritis (RA). We studied children with RF+ and/or anticyclic citrullinated peptide antibody (anti-CCP)+ JIA to determine what proportion of those children meet International League of Associations(More)
BACKGROUND The association between rheumatoid arthritis (RA) and periodontitis is well established. Some children with juvenile idiopathic arthritis (JIA) phenotypically resemble adults with RA, characterized by the presence of anti-cyclic citrullinated peptide (CCP) antibodies. We sought to investigate an association between CCP-positive JIA and symptoms(More)
Juvenile idiopathic arthritis (JIA), the most common cause of chronic arthritis in children, is believed to be influenced by genetic factors. Recent studies on the genetics of JIA have not only validated proposed genetic associations but have also led to the recognition of novel genetic associations. Studies of specific genes have been modeled on the(More)
OBJECTIVE Children with childhood-onset rheumatoid arthritis (RA) include those with rheumatoid factor or anti-citrullinated protein antibody-positive juvenile idiopathic arthritis. To test the hypothesis that adult-onset RA-associated variants are also associated with childhood-onset RA, we investigated RA-associated variants at 5 loci in a cohort of(More)
