ACE inhibitor use and severe angioedema

Using a bradykinin blocker in ACE inhibitor-associated angioedema in the emergency department

We report two cases of ACE inhibitor-associated angioedema and critical airway compromise, where the use of a selective bradykinin 2 receptor blocker resulted in rapid symptom resolution and prevented intubation to protect the airway.

Severe angioedema induced by angiotensin converting enzyme inhibitors: role of precipitating factors

Angiotensin converting enzyme inhibitors like captopril, enalapril, lisinopril, trandopril and ramipril may rarely induce a life threatening angioedema. We present two cases of severe angioedema induced by enalapril and ramipril along with possible precipitating factors observed in these patients. The importance of prompt recognition and early management of such cases is emphasized.

Hereditary angioedema first apparent in the ninth decade during treatment with ACE inhibitor

BACKGROUND

Hereditary angioedema ordinarily manifests itself in childhood. The development of angioedema in this disease and as a side effect of angiotensin-converting enzyme inhibitor treatment is caused by similar mechanisms.

METHODS

We report a case of female patient, diagnosed with hereditary angioedema at age 90, who experienced the first attack 8 years earlier during angiotensin-converting enzyme inhibitor use.

CONCLUSIONS

This patient presented with her first episode of hereditary angioedema at the oldest age ever reported. A careful family history, especially for angioedema, should be taken in patients of all ages before initiating treatment with angiotensin-converting enzyme inhibitor.
