[TINU syndrome and lymphoid interstitial alveolitis: a new observation].

BACKGROUND
TINU syndrome is a rare entity known Dobrin disease, combining uveitis mostly bilateral and recurrent with acute tubulo interstitial nephritis (AIN) occurring in young adults. The etiology and pathogenesis of this syndrome remain unknown.


AIM
To report a new case of TINU syndrome and to discuss its etiopathogenesis.


CASE REPORT
This 33 year old women is hospitalized for exploration of acute renal failure, in a context of deterioration of general condition, associated with a unilateral anterior uveitis. The bronchoalveolar lavage showed lymphoid interstitial alveolitis with CD4 and the renal biopsy found lesions characteristic of AIN. Evolution under corticoïd treatment was favorable.


CONCLUSION
Lymphoid interstitial alveolitis associated with TINU syndrome has been reported only twice before. The discovery of a TINU syndrome must practice bronchoalveolar lavage in search of sub clinical pulmonary involvement.
