Sjogren's syndrome is an autoimmune exocrinopathy that develops into systemic autoimmune disease in 25% of patients, leading to general complications, one of which is kidney involvement. It presents mainly as interstitial nephritis, disclosed by hyposthenuria, distal renal tubular acidosis and diabetes insipidus. We here describe one case of secondary Sjogren syndrome with distal renal tubular acidosis who developed nephrocalcinosis and renal insufficiency.
