title: Granulomatous nephritis and chronic renal failure in sarcoidosis. Long-term follow-up studies in two patients.
abstract: Sarcoid granulomatous nephritis was observed in 2 patients. Renal failure was present in both patients in the absence of hypercalcemia or nephrocalcinosis. Specific tubular dysfunction manifested as an acquired Fanconi syndrome in 1 patient. Steroid therapy was effective in causing regression of the renal granuloma, but there were significant interstitial changes on repeat renal biopsy which were accompanied by persistent tubular dysfunction. Sarcoid granulomatous nephritis may be a not infrequent cause of renal dysfunction in sarcoidosis.
