Brief Summary:
Specific treatments for angiotensin-converting-enzyme inhibitor (ACE-I) and angiotensin-receptor-blocker (ARB)-induced angioedema exist. Early access to these treatments is challenging because they are expensive and have short shelf lives making it illusory that all emergency department (ED) stock them. The aim of this retrospective study was to define, for each patient with a confirmed ACE-I or ARB-induced angioedema, at which step of the care, the specific treatment was administered. The second objective was to analyse the availability of these treatment in the area around Lyon, France and the factors that may influence it.

Condition or disease

Official Title: Efficient Treatments for ACE-I and ARB-induced Angioedema Exist and Should be Available to All Patients. Analysis of Their Availability and Influencing Factors in the Area Around Lyon, France
Study Start Date : February 2016
Actual Primary Completion Date : March 2016
Actual Study Completion Date : March 2016

Primary Outcome Measures :
  1. Step of the care allowing the patients to benefit from a specific treatment. [ Time Frame: October 2010 to December 2014 ]
    Three answers are possible. Patients were treated with the specific medication (icatibant or C1-inhibitor concentrate) either in the first ED or by the medical ambulance team, or by the investigators reference center's intensive care unit.

Secondary Outcome Measures :
  1. Epidemiological characteristics [ Time Frame: October 2010 to December 2014 ]
    The investigators collect data such as age, sex, localization of the angioedema.

  2. Triggering treatments [ Time Frame: October 2010 to December 2014 ]
    The investigators detail which ACE-inhibitor, which ARB and eventually which co-medication was taken and triggered the angioedema.

Sampling Method:   Non-Probability Sample
Study Population
Patients treated with a specific treatment for bradykinin-mediated angioedema for a severe attack of angioedema due to ACE-inhibitors or ARB during the study period.

Inclusion Criteria:

  • Every patient followed for the first time in our reference center for severe confirmed ACE-I or ARB-induced angioedema. Data were analyzed from patients attended either in a specialized angioedema consultation or during a hospitalization in our intensive care unit.
  • Severe attack was defined either by its localization over the shoulder or by an severe abdominal attack.

Exclusion Criteria:

- Patients which received no specific treatment (icatibant, C1-inhibitor concentrate) were excluded.
