Antinuclear antibody and HLA-B27 positive uveitis: combination of two diseases?

Abstract

AIMS/BACKGROUND Anterior uveitis associated with juvenile chronic arthritis concerns two different clinical entities: firstly, antinuclear antibody (ANA) positive patients who have a chronic anterior uveitis with severe complications and often a poor visual prognosis; secondly, usually HLA-B27 positive children, predominantly boys, with unilateral recurrent anterior uveitis. Three patients are described who had a combination of clinical and laboratory features of both diseases.

METHODS Retrospective clinical and laboratory analysis of three patients.

RESULTS Ocular features in the three patients combined the clinical picture of ANA positive chronic anterior uveitis during early childhood with the clinical features of HLA-B27 unilateral acute anterior uveitis during adolescence. The patients fulfilled the diagnostic criteria of juvenile chronic arthritis, and they had no ankylosing spondylitis. All three patients had the HLA-B*2705 subtype.

CONCLUSIONS Whether the association of ANA positive chronic anterior uveitis and HLA-B27 unilateral acute anterior uveitis is a coincidence or represents a distinct clinical entity is not yet clear.
