RESUMEN
PURPOSE OF REVIEW: The aim of this review is to highlight recent changes in the treatment of juvenile idiopathic arthritis (JIA) - associated uveitis in the era of biologics. RECENT FINDINGS: Early introduction of steroid-sparing therapies is paramount for appropriate management. Biologic therapies have improved the therapeutic management of JIA-uveitis and adalimumab is currently approved for pediatric-onset noninfectious chronic anterior uveitis with an inadequate response to topical steroids and methotrexate. Recent studies suggest that ocular complications in JIA-uveitis are less frequent compared with previous publications. However, patients with JIA-uveitis seem to be particularly dependent on classical immunosuppressive drugs or biologics. Indications for primary lens implantation have expanded considerably with the evolution of materials and better control of inflammation with biologics. The rate of serious adverse events related to new therapeutic approaches seem acceptable, however longer term follow-up is necessary. SUMMARY: Improvement in the initial screening and improved inflammation control with biologics has considerably reduced the potentially sight-threatening prognosis of JIA-uveitis.

LRBA (lipopolysaccharide-responsive and beige-like anchor protein) deficiency associates immune deficiency, lymphoproliferation, and various organ-specific autoimmunity. To date, prevalent symptoms are autoimmune cytopenias and enteropathy, and lymphocytic interstitial lung disease. In 2 siblings from a consanguineous family presenting with early onset polyautoimmunity, we presumed autosomal recessive inheritance and performed whole exome sequencing. We herein report the first case of early-onset, severe, chronic polyarthritis associated with LRBA deficiency. A novel 1bp insertion in the LRBA gene, abolishing protein expression, was identified in this family. Among the 2 brothers homozygous for LRBA mutation, one developed Evans syndrome and deceased at age 8.5 from complications of severe autoimmune thrombocytopenia. His brother, who carried the same homozygous LRBA mutation, early-onset erosive polyarthritis associated with chronic, bilateral, anterior uveitis and early onset type 1 diabetes mellitus. This report widens the clinical spectrum of LRBA deficiency and, in lights of the variable phenotypes described so far, prompts us to screen for this disease in patients with multiple autoimmune symptoms in the family, including severe, erosive, polyarticular juvenile arthritis.

OBJECTIVE: Few studies have assessed Health-Related Quality of Life (HR-QoL) in adults following juvenile idiopathic arthritis, and none since the advent of biotherapies. The aim of our study is to assess the impact of juvenile idiopathic arthritis on quality of life in a large transitional cohort, evaluate which factors influence quality of life in juvenile idiopathic arthritis, and determine which questionnaire should be used in practice. METHODS: All consecutive juvenile idiopathic arthritis patients followed during adulthood in a transitional care program were included. Demographical, clinical and biological data were collected. The following quality of life questionnaires were administered: SF36 and EuroQoL. Age- and sex-matched controls (without rheumatic disease) were included. RESULTS: One hundred and sixty-one juvenile idiopathic arthritis (120 women and 41 men) and 76 (51/25) controls were included. Out of 161, sixty-five (40%) were considered to be in remission. Juvenile idiopathic arthritis had a large impact on the physical scales of quality of life. Pain seemed to be the most important factor affecting quality of life in cases of juvenile idiopathic arthritis. No significant difference was found between sub-types of juvenile idiopathic arthritis. CONCLUSION: In this large transitional cohort of patients at the era of biotherapies, juvenile idiopathic arthritis has a larger effect on physical than mental scale of quality of life measures. Pain was the main factor influencing quality of life. Sub-types of juvenile idiopathic arthritis do not seem to influence quality of life.
