Treatment with C1 inhibitor concentrate in abdominal pain attacks of patients with hereditary angioedema

2005

BACKGROUND: Abdominal edema attacks in patients with hereditary angioedema are often extremely painful, associated with vomiting and diarrhea, and have a high potential for causing recurrent disability of the patient. STUDY DESIGN AND METHODS: Intraindividual comparison of retrospective data in 75 hereditary angioedema patients comprising 4,834 abdominal attacks treated with C1 inhibitor concentrate versus 17,444 untreated abdominal attacks. RESULTS: The mean duration of abdominal attacks was 92.0 hours (SD, 40.8 hr) when untreated compared to 39.9 hours (SD, 30.0 hr) when treated. Patients reported a mean maximal pain score of 8.6 (SD, 1.7; range, 1-10) for untreated attacks compared to 4.…

Hereditary Angioedema: New Findings Concerning Symptoms, Affected Organs, and Course

2005

Abstract Purpose Hereditary angioedema (HAE) due to C1 inhibitor deficiency is clinically characterized by relapsing skin swellings, abdominal pain attacks, and life-threatening upper airway obstruction. Our aim was to examine a temporal and spatial pattern of the edema episodes by evaluating the long-term course of hereditary angioedema in order to establish a specific swelling pattern. Subjects and methods Data were generated from 221 patients with C1 inhibitor deficiency by asking them about symptoms they experienced during their edema episodes. Documentation was accomplished through the use of standardized questionnaires. Results A total of 131110 edema episodes were observed. Clinical …
