Asphyxiation by laryngeal edema in patients with hereditary angioedema.

2000

Objective To describe the occurrence of fatal laryngeal edema in patients with hereditary angioedema due to C1 esterase inhibitor deficiency. Patients and Methods We describe 6 patients from various regions of Germany who died from laryngeal edema within the last 10 years. Furthermore, we conducted a retrospective survey of 58 patients with hereditary angioedema, originating from 46 affected families. The data were obtained from the attending physicians and from the patients' relatives. Results Among the 6 reported patients, aged 9 to 78 years, hereditary angioedema had been diagnosed in 3 and was undiagnosed in 3. None of them had an emergency cricothyrotomy or received C1 inhibitor concen…

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 …

Hereditary angioedema with normal C1 inhibitor: clinical symptoms and course.

2007

Abstract Purpose A new type of hereditary angioedema was described recently. It was characterized by recurrent bouts of angioedema in various organs and normal C1 inhibitor and was observed mainly in women. Our aim was to conduct a detailed study of the clinical features of this condition. Methods A total of 138 patients with hereditary angioedema and normal C1 inhibitor who belonged to 43 unrelated families were examined through the use of standardized questionnaires. Results A majority of patients with hereditary angioedema and normal C1 inhibitor had skin swellings (92.8%), tongue swellings (53.6%), and abdominal pain attacks (50%). Laryngeal edema (25.4%) and uvular edema (21.7%) also w…

Sudden upper airway obstruction in patients with hereditary angioedema.

2003

Hereditary angioedema (HAE) is clinically characterized by recurrent and self-limiting skin, intestinal, and life-threatening laryngeal edema. This study describes the age at which laryngeal edema first occurred, the time between onset and full development, and the effectiveness of therapy and prophylaxis in 123 HAE patients. 61 (49.7%) patients experienced a total of 596 laryngeal edema episodes. The ratio of laryngeal edema episodes to skin swellings and abdominal pain attacks was approximately 1:70:54 in patients who had laryngeal edema. The mean (SD) age at the first laryngeal edema was 26.2 (15.3) years. Nearly 80% of the laryngeal edemas occurred between age 11 and 45. The mean interv…

Clinical studies of sudden upper airway obstruction in patients with hereditary angioedema due to C1 esterase inhibitor deficiency.

2003

Background Hereditary angioedema due to C1 esterase inhibitor deficiency is clinically characterized by recurrent and self-limiting skin, intestinal, and laryngeal edema. Asphyxiation by laryngeal edema is the main cause of death among patients who die of hereditary angioedema. This study describes the age at which laryngeal edema first occurs, the time between onset and full development, and the effectiveness of therapy and prophylaxis. Methods Information on 123 patients with hereditary angioedema was obtained from medical histories and reports by the general practitioners, emergency physicians, and hospitals involved. Results Sixty-one patients (49.6%) experienced a total of 596 laryngea…

Risk of laryngeal edema and facial swellings after tooth extraction in patients with hereditary angioedema with and without prophylaxis with C1 inhib…

2010

Objective Tooth extractions may trigger clinical symptoms of hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH). The aim of this study was to determine how many tooth extractions were followed by symptoms of HAE-C1-INH in patients with and without preoperative short-term prophylaxis with C1 inhibitor concentrate. Study design Tooth extractions and clinical symptoms of HAE-C1-INH were determined from clinical record files of 171 patients with HAE-C1-INH. Results Facial swelling or potentially life-threatening laryngeal edema, or both, occurred in 124/577 tooth extractions (21.5%) without prophylaxis. Similar symptoms occurred in a fewer proportion of patients undergoing extrac…

Angioedema due to acquired C1-inhibitor deficiency: spectrum and treatment with C1-inhibitor concentrate

2018

Abstract Background Acquired angioedema due to C1-inhibitor (C1-INH) deficiency (AAE-C1-INH) is a serious condition that may result in life-threatening asphyxiation due to laryngeal edema. It is associated with malignant B-cell lymphoma and other disorders. The purpose of this study was to describe the characteristics and associated disorders of patients with AAE-C1-INH and assess the efficacy of plasma-derived C1-INH concentrate (pdC1-INH) in the treatment of AAE-C1-INH. Forty-four patients with AAE-C1-INH from the Angioedema Outpatient Service of Mainz were assessed for associated disorders. In 32 of these patients, the duration of swelling attacks was measured before and after treatment …

Hereditary Angioedema with Normal C1 Inhibitor Activity Including Hereditary Angioedema with Coagulation Factor XII Gene Mutations

2006

Recurrent angioedema of the skin is a commonly diagnosed clinical symptom that can be found in various clinical entities [1,2]. Some types of angioedema of the skin are associated with episodes of upper airway obstruction that may be life threatening. Death by asphyxiation from laryngeal edema is well known in hereditary angioedema (HAE) due to C1 inhibitor deficiency [3,4] and in recurrent angioedema induced by angiotensinconverting enzyme (ACE) inhibitors [5–9]. Therefore, it is important to determine the exact type of angioedema in each patient. In many patients angioedema is associated with urticaria. If relapsing urticaria occurs simultaneously or alternately with angioedema, both cond…

Previously undiagnosed Reinke edema as a cause of immediate postextubation inspiratory stridor

2015

Reinke edema (RE) is an uncommon lesion of the vocal folds and a potential cause of complications during airway management. We report the case of a woman with previously unknown RE admitted to the intensive care unit who experienced postextubation inspiratory stridor immediately after separation from mechanical ventilation. RE should be considered among causes of postextubation stridor.
