Abstract
PURPOSE: We investigated inflammatory cell infiltrates in iris biopsies in uveitis associated with juvenile idiopathic arthritis (JIA) in comparison with other pediatric uveitis entities and noninflammatory pediatric controls.
METHODS: Iridectomy specimens were obtained during elective trabeculectomy from 31 eyes of 25 patients: 12 eyes with JIA-associated uveitis, 13 eyes with other uveitis entities, and 6 eyes with open angle nonuveitic juvenile glaucoma. Histopathologic and immunohistochemical analyses were performed. A semiquantitative scoring system was used with a scale ranging from 0 to 4 depending on the number of stained cells.
RESULTS: An inflammatory infiltrate was present in 8/12 (67%) specimens with JIA-associated uveitis. The cellular infiltrate in JIA specimens was characterized by the presence of CD138+ plasma cells and CD68+ macrophages, while the presence of CD20+, CD4+, and CD8+ cells was variable. Presence of plasma cells in the inflammatory infiltrates in anterior uveitis correlated with antinuclear autoantibody (ANA) positivity regardless of the diagnosis of JIA. CD4+ and CD8+ T cells were not always detectable in the iris biopsies of all childhood uveitis patients, although a slight predominance of CD4+ cells was noted.
CONCLUSIONS: Children with ANA-positive anterior uveitis often show an infiltrate of plasma cells, regardless of the diagnosis of JIA. The iris of JIA-associated uveitis patients is additionally characterized by the presence of various numbers of macrophages.
