    Objectives Juvenile idiopathic arthritis (JIA) affects children of all races. Prior studies suggest that phenotypic features of JIA in African American (AA) children differ from those of Non-Hispanic White (NHW) children. We evaluated the phenotypic differences at presentation between AA and NHW children enrolled in the CARRA Registry, and replicated the findings in a JIA cohort from a large center in South Eastern USA. Methods Children with JIA enrolled in the multi-center CARRA Registry and from Emory University comprised the study and replication cohorts. Phenotypic data on Non-Hispanic AA children were compared with NHW children with JIA using Chi-square, Fisher's exact and Wilcoxon rank sum tests. Results In all, 4177 NHW and 292 AA JIA cases from the CARRA Registry, and 212 NHW and 71 AA cases from Emory were analyzed. AA subjects more often had RF-positive polyarthritis in both CARRA (13.4% vs. 4.7%, p=5.3×10-7) and Emory (26.8% vs. 6.1%, p =1.1×10-5) cohorts. AA children had positive tests for RF and CCP more frequently, but oligoarticular or early onset ANA-positive JIA less frequently in both cohorts. AA children were older at onset in both cohorts and this difference persisted after excluding RF-positive polyarthritis in the CARRA Registry (median age 8.5 vs. 5.0 years; p =1.4×10-8). Conclusions Compared to NHW children, AA children with JIA are more likely to have RF/CCP positive polyarthritis, and are older at disease onset, and less likely to have oligoarticular or ANA-positive early onset JIA, suggesting that the JIA phenotype is different in African American children.

  • Brief Report: Susceptibility to Childhood-Onset Rheumatoid Arthritis: Investigation of a Weighted Genetic Risk Score That Integrates Cumulative Effects of Variants at Five Genetic Loci

    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 patients with childhood-onset RA. We also assessed the cumulative association of these variants in susceptibility to childhood-onset RA using a weighted genetic risk score (wGRS).

    BackgroundComplementary and alternative medical (CAM) therapies are commonly used by pediatric patients with chronic medical conditions. Little is known about parents' perceptions of these therapies. This study describes the views of parents of patients with juvenile idiopathic arthritis (JIA) regarding conventional and CAM therapies.MethodsParents of children with JIA seen at a pediatric rheumatology clinic were surveyed between June 1 and July 31, 2007. Questionnaires asked about patients' use of over 75 therapies in the past 30 days, their perceived helpfulness (0 = not helpful; 3 = very helpful), perceived side effects (0 = none; 3 = severe), and whether each therapy would be recommended to other patients with JIA (Yes, No, Not sure).ResultsQuestionnaires were returned by 52/76 (68%) parents; patients' average age was 10.9 years and 87% were Caucasian. Medications were used by 45 (88%) patients; heat (67%) and extra rest (54%) were also commonly used. CAM therapies were used by 48 (92%), e.g., massage (54%), vitamins and other supplements (54%), avoiding foods that worsened pain (35%) and stress management techniques (33%). Among the therapies rated by 3 or more parents, those that scored 2.5 or higher on helpfulness were: biologic medications, methotrexate, naproxen, wheelchairs, orthotics, heat, vitamins C and D, music, support groups and prayer. CAM therapies had 0 median side effects and parents would recommend many of them to other families.ConclusionJIA patients use diverse therapies. Parents report that many CAM therapies are helpful and would recommend them to other parents. These data can be used in counseling patients and guiding future research.
