Clinical management algorithm of uveitis associated with juvenile idiopathic arthritis: interdisciplinary panel consensus.

Uveitis associated with juvenile idiopathic arthritis (JIA) typically involves the anterior chamber segment, follows an indolent chronic course, and presents a high rate of uveitic complications and a worse outcome as compared to other aetiologies of uveitis. Disease assessment, treatment, and outcome measures have not been standardized. Collaboration between pediatric rheumatologists and ophthalmologists is critical for effective management and prevention of morbidity, impaired vision, and irreparable visual loss. Although the Standardization of Uveitis Nomenclature Working Group recommendations have been a great advance to help clinicians to improve consistency in grading and reporting data, difficulties arise at the time of deciding the best treatment approach in the individual patient in routine daily practice. For this reason, recommendations for a systematized control and treatment strategies according to clinical characteristics and disease severity in children with JIA-related uveitis were developed by a panel of experts with special interest in uveitis associated with JIA. A clinical management algorithm organized in a stepwise regimen is here presented.

Clinical and genetic heterogeneity among Spanish patients with recurrent autoinflammatory syndromes associated with the CIAS1/PYPAF1/NALP3 gene.

OBJECTIVE: To investigate the involvement of the CIAS1/PYPAF1/NALP3 gene in 7 unrelated Spanish families with recurrent autoinflammatory diseases characterized by early onset, recurrent fever, and a chronic urticarial rash, in whom a clinical diagnosis of cryopyrin-associated periodic syndromes (CAPS) is suspected. METHODS: Clinical symptoms, results of laboratory analyses, and data on previous treatments in members of the 7 families were recorded on a questionnaire specific for hereditary autoinflammatory diseases. All coding regions and intronic flanking boundaries of the CIAS1/PYPAF1/NALP3 gene were amplified by polymerase chain reaction and sequenced. RESULTS: Five different missense mutations, including 2 de novo and 1 previously unreported mutation (R488K), were identified in exon 3 of the CIAS1/PYPAF1/NALP3 gene in 5 of the 7 affected families. Expanded genetic analysis among the healthy individuals identified incomplete penetrance in 2 families. No mutations were found in 2 of the 3 patients with chronic infantile neurologic, cutaneous, articular (CINCA) syndrome/neonatal-onset multisystem inflammatory disease (NOMID). CONCLUSION: The clinical data suggested a diagnosis of familial cold-induced autoinflammatory syndrome in 3 families, CINCA/NOMID syndrome in 3 others, and a possible Muckle-Wells syndrome, whereas mutational analysis showed different CIAS1/PYPAF1/NALP3 missense mutations in 5 families. These data are consistent with a common molecular basis of these diseases and highlights the phenotypic heterogeneity among CIAS1/PYPAF1/NALP3 gene-associated syndromes. The previously unreported mutation and the incomplete penetrance found in 2 families expand the genetic basis underlying these autoinflammatory syndromes. These findings should alert clinicians to the possible genetic basis of these conditions, even in the absence of a family history, in their attempts to establish an accurate diagnosis and the optimal therapeutic approach.
