Recurrence and spontaneous remission of nephrotic syndrome in secondary renal amyloidosis

: Secondary systemic amyloidosis (AA) occurs in association with chronic inflammatory disorders and chronic infections. Regression can occur after therapeutically induced remission of the underlying disease; spontaneous remissions has been reported infrequently. We report a 61 year-old woman, with antecedent pulmonary tuberculosis, who developed a nephrotic syndrome at the time of a respiratory infection. Renal biopsy showed secondary amyloidosis. Remission in the nephrotic syndrome appeared spontaneous, but it recurred in the course of pneumonia, and had a second spontaneous remission a maintained at present.
