HLA-DR, DQ Class II DNA Typing in Pediatric Panuveitis and Tubulointerstitial Nephritis and Uveitis (TINU) – Accepted Manuscript

Abstract: Purpose: To describe chorioretinal lesions in pediatric uveitis that are strongly associated with the HLA-DR,DQ Class II type associated with tubulointerstitial nephritis and uveitis (TINU).Design: Retrospective, observational case series.Methods: Results: Fourteen of the 15 patients (93%) with otherwise unexplained pediatric panuveitis typed HLA-DRB1*01-HLA-DQB1*05. Eleven of 15 (73.3%) had bilateral sharply demarcated, usually inferior, 200-300 micron spots of chorioretinal atrophy, and 4 of 15 (27.7%) had bilateral clusters of 500-750 micron poorly defined orange choroidal lesions without overlying atrophy of the retinal pigment epithelium. None had interstitial nephritis. Four of the 6 definite TINU cases had Class II typing and (Read more...)
