IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Objective: To investigate, for the first time, the frequency of recurrences of angiotensin-converting enzyme inhibitor (ACE-I)-related angioedema after the discontinuation of ACE-I. Methods: This retrospective study was conducted in an outpatient tertiary-level centre for a total period of 173 months (about 14 years). Consecutive patients with recurrent angioedema symptoms, initiated during treatment with an ACE-I, who had been followed for at least 12 months after discontinuation of the drug were eligible. The primary study variable was the incidence of recurrences of angioedema after ACE-I discontinuation. Angioedema location, type of ACE-I and indication for this treatment and the drugs prescribed after the discontinuation of ACE-I were also evaluated. Results: In total, 111 patients were followed; 54 of them (49%) were on enalapril. After discontinuation from ACE-I, 51 patients (46%) had further recurrences of angioedema; in 18 relapsers (16% of the total), the frequency of angioedema recurrences remained unchanged when compared with that reported during ACE-I treatment. The large majority of relapsers (88%) had the first recurrence of angioedema within the first month since ACE-I discontinuation. The switch to a different antihypertensive therapy did not seem associated with a reduction in the frequency of angioedema attacks. Conclusion: Even with all the limitations on any observational analysis, this long-term study suggests for the first time that patients with angioedema started while on ACE-I treatment seem to have a condition predisposing to angioedema that is elicited by the treatment with these drugs. Further studies in this field appear advocated due to the potential severity of angioedema attacks.
