Angiotensin I in peritoneal dialysis fluid improved hypotension: a case report

In a bilateral nephrectomized woman undergoing continuous ambulatory peritoneal dialysis, angiotensin I instilled intraperitoneally with the dialysis fluid prevented the fall in systemic blood pressure at peritoneal dialysis and elevated, in high doses, the systemic blood pressure in a dose-dependent manner over the whole observation period. The blood pressure lowering effect could be completely reversed by infusion of the angiotensin II receptor antagonist, saralasin. However, some side effects observed, like increased motility of gut, diarrhea and abdominal pain probably will limit the application of the drug in clinical routine.
