Amyloidosis frequently affects the kidney leading to proteinuria and loss of function. In cases of AA (reactive/inflammatory) amyloidosis, it is sometimes possible to quench the stimulus to chronic inflammation and by so doing stop further elaboration and deposition of amyloid fibrils. We describe the case of a man with a long-standing empyema who developed nephrotic syndrome and renal impairment. The empyema was resected and shortly afterwards proteinuria disappeared and renal function improved. Strenuous efforts are mandatory to locate and definitively treat underlying inflammatory foci in AA amyloidosis.
