title: Effect of angiotensin-converting enzyme inhibition on nephropathy in patients with a remnant kidney.
abstract: OBJECTIVE
  This study was performed to evaluate the effect of angiotensin-converting enzyme inhibitor (ACEI) therapy and dietary protein restriction on nephropathy involving a remnant kidney.
  
  
  METHODS
  Five patients with proteinuria > or = 5 years following partial removal of a solitary kidney were treated with a low-protein diet and an ACEI agent. Four patients had biopsy-proven focal segmental glomerulosclerosis. The daily urinary protein excretion ranged from 1240 to 10,032 mg. The serum creatinine levels ranged from 1.2 to 3.1 mg/dL.
  
  
  RESULTS
  The post-treatment follow-up interval ranged from 18 to 30 months. The treatment regimen was well tolerated in all patients. Four patients experienced a reduction in the urinary protein level while maintaining stable overall renal function. In 1 patient, the urinary protein level increased and renal function gradually deteriorated following ACEI therapy.
  
  
  CONCLUSIONS
  These preliminary data suggest that ACEI therapy and a low-protein diet may mitigate nephropathy associated with a remnant kidney.
