Colchicine induced remission in amyloid nephrotic syndrome.

An unusual case of reversible reactive amyloidosis (AA) is described. A patient in the course of lobar pneumonia developed acute transient nephrotic syndrome and renal failure. Renal and liver biopsy showed amyloidosis and positive immunohistochemistry stains for amyloid A protein. The nephrotic syndrome resolved completely following 6 months of colchicine treatment and the urine is protein free after 6 years of follow-up.
