Idiopathic acute interstitial nephritis associated with anterior uveitis in adults.
Concomitant renal and ocular lesions have been described in a few systemic diseases. The association of acute interstitial nephritis (AIN) and anterior uveitis without determined cause was first described in children. Recently, the same clinical association has been reported in adults. We report 3 cases of this association and present a review of the literature. Including our 3 patients, 7 cases of this association have been reported in adults. All patients were females aged 27-74 years. Initial symptoms were either ocular, or pseudoviral (fever, myalgia and fatigue). Histological renal studies revealed acute interstitial nephritis with tubular lesions. Immunofluorescence and electron microscopy were not contributive. Ocular prognosis was always good. In 5 patients, the evolution of renal function was excellent with complete resolution of acute renal failure within a few weeks. Chronic renal failure developed in two of the four patients who did not receive systemic steroid therapy (with evolution towards terminal renal failure in one patient). Three of the patients received 60 mg per day of prednisone and none of them developed chronic renal failure. Despite the small number of patients reported and the possibility of spontaneous regression, these data suggest a beneficial effect of systemic steroid therapy to prevent or reduce interstitial inflammation and subsequent fibrosis.
