SIR, In 1975, Dobrin et al. [1] described tubulointerstitial nephritis uveitis syndrome (TINU) in two women with anterior uveitis and tubulointerstitial nephritis. Since then
140 cases have been described in the literature.
The pathogenesis of TINU is poorly understood. Suppression of peripheral cell-mediated immunity leading to skin anergy and locally increased immune reactivity, analogous to sarcoidosis, is likely to play a significant role. This local proliferation of T helper cells also occurs in SS suggesting that similar physiopathogenic mechanisms may act across these three diseases [2–5]. Unlike SS and sarcoidosis, TINU is not known to be associated with arthritis. We present a case of TINU in association with an erosive arthropathy of the hip, a feature that has not been previously described.
