Revision as of 16:13, 10 December 2020
Background
- Angioedema is paroxysmal, nondemarcated swelling of dermal or submucosal layers of skin or mucosa
- Swelling is asymmetric, nonpitting, and nonpruritic, however can be associated with allergic features depending on cause
- Isolated uvular angioedema, or Quincke's disease, is a relatively rare presentation of angioedema of the upper airway
Etiologies
- Allergic angioedema: IgE–mediated type I hypersensitivity reaction
- Hereditary angioedema: Congenital or acquired loss of C1 esterase inhibitor
- Due to C1 esterase inhibitor deficiency
- Leads to unregulated activity of vasoactive mediators (bradykinin) associated with complement pathway
- Autosomal dominant
- Edema of face, extremities, bowel wall
- ACE-I induced angioedema: ACEI adverse reaction from excessive bradykinin
- Idiopathic angioedema
Clinical Features
- Angioedema
- Swelling most often includes face, lips, and/or tongue
- May also involve[1]:
- Upper airway--> respiratory distress, stridor
- Face, hands, genitals
- Intestines--> nausea/vomiting, abdominal pain, diarrhea, SBO-like presentation
Differential Diagnosis
Acute allergic reaction
- Allergic reaction/urticaria
- Anaphylaxis
- Angioedema
- Anxiety attack
- Asthma exacerbation
- Carcinoid syndrome
- Cold urticaria
- Contrast induced allergic reaction
- Scombroid
- Shock
- Transfusion reaction
Evaluation
Hereditary angioedema
- Suspect in patients with history of recurrent peripheral angioedema and abdominal pain
- 75% experience onset of symptoms before age 15yr
- C4 level screens for HAE (suspect if low)
- Decreased levels of C1 and C4 esterase inhibitors confirms diagnosis
ACE inhibitor-induced angioedema
- Incidence is highest within the first month; however, may occur at anytime
- 40% present months to years after initial dose[2]
- Incidence is 0.1-2.2% (more common in blacks)
- Physiology more closely related to bradykinin-mediated pathway than IgE-mediated pathway, therefore current treatments may be insufficient
Management
General
- Consider Epinephrine 0.3mg IM if there is any concern this could be allergic in nature
- Consider Glucagon 1-5mg IV if patient is on beta-blockers and not responding to Epinephrine
- Consider Tranexamic acid (1 g IV, over 10 min) for bradykinin-mediated angioedema [3][4]
- FFP for possible etiology related to bradykinin or C1-esterase deficiency[5]
- 2 units
- Consider definitive airway if voice change, hoarseness, stridor, dyspnea
- Prepare for a difficult airway which can include need for fiberoptics, ENT/anesthesia assistance, surgical airway, or transfer to the OR
Hereditary Angioedema
First-Line Therapies
- C1 inhibitor (C1INH)[6]
- 1000 units if ≤50kg
- 1500 units if >50-75kg
- 2000 units if >75-100kg
- 2500 units if >100kg
- Ecallantide
- 10mg SQ x 3 in different anatomical locations (30mg in total)
- Icatibant
- 30mg SQ
ACE-I Induced Angioedema
- Typical anaphylaxis medications do not effect bradykinin levels[7], but consider:
- Epinephrine 0.3mg IM
- Diphenhydramine 50mg IV
- Methylprednisolone 125mg IV
- Consider Tranexamic acid (1 g IV, over 10 min) for bradykinin-mediated angioedema [8][9]
- Icatibant
- 30mg SQ
- Significantly decreases time to complete resolution (8 hrs vs 27.1 hrs)[10]
- Note: control group did not receive FFP
- Consider Ecallantide
Disposition
- Consider discharge after 4-6 hrs observation if there is no airway edema and patient improves or swelling remains isolated to face and lips only
- 24 hrs obs if epinephrine given
Ishoo Staging
Ishoo Staging may predict severity of disease to help stratify disposition. It is based on retrospective study[13]
Stage | Area | Outpatient | Floor | ICU | Advanced Airway |
1 | Face/lip | 48% | 52% | 0% | 0% |
2 | Soft palate | 60% | 40% | 0% | 0% |
3 | Tongue | 26% | 7% | 67% | 7% |
4 | Larynx | 0% | 0% | 100% | 24% |
