title: [Angioedema during ACE and DPP-4 inhibition].
abstract: Angioedema is a rare side effect of angiotensin converting enzyme (ACE) inhibitors. Its cause is probably related to the accumulation of bradykinin and substance P, i.e. two proinflammatory peptides normally inactivated by ACE. Angioedema occurs most of the time at the early phase of treatment, but may also develop during long-term treatment. It might involve the gastro-intestinal tract, leading to abdominal pain, vomiting and/or diarrhea, as well as pancreatitis. Dipeptidyl-ptidase-4 (DPP-4) is another enzyme allowing the degradation of bradykinin and substance P. Co-administering an ACE inhibitor and a DPP-4 inhibitor (as an antidiabetic agent) increases significantly the risk of angioedema.
