Tubulointerstitial Nephritis and Uveitis Syndrome (TINU) after Intake of Dietary Supplement.

ABSTRACT

INTRODUCTION: The pathogenesis of tubulointerstitial nephritis with uveitis syndrome (TINU) is thought to be an interplay between environmental and genetic factors leading to an inappropriate immune response. METHODS: Report of a clinical case. RESULTS: We present a case of TINU syndrome which meets the clinical and anatomopathological features according to the classification criteria of the standardization of uveitis nomenclature (SUN) working group. The only possible causal agent was found to be the intake of a nutritional supplement. CONCLUSION: Our case highlights the role of environmental factors as triggers for this disorder.
