Types of Angioedema
Angioedema comes in many forms, each with its unique causes and symptoms. It’s important to know about each type. This helps with the right diagnosis and treatment.
1. Hereditary Angioedema (HAE)
Hereditary angioedema is rare, caused by a gene problem. It makes a protein, C1-inhibitor, not work right. This leads to swelling in parts like the face and gut. Fast treatment is key to avoid serious problems.
2. Acquired Angioedema
Acquired angioedema can show up in many ways and is often linked to health conditions or some drugs. In this type, the body’s own substances stop the regular control of bradykinin. This results in sudden swelling.
3. Angiotensin-Converting Enzyme Inhibitor-Induced Angioedema
ACE inhibitors, often used for high blood pressure, can also cause angioedema. They affect how bradykinin is broken down, leading to swelling. Stopping these medications is necessary if this happens.
4. Histaminergic Angioedema
This type is due to too much histamine. It’s often seen with hives and can be from allergies, bug bites, or certain drugs. Treating it usually involves antihistamines and staying away from triggers.
5. Nonhistaminergic Angioedema
Nonhistaminergic angioedema doesn’t mainly involve histamine. It’s caused by other things, often bradykinin. This includes some unique kinds of angioedema with their approach to treatment.
Clinical Considerations
Getting the right kind of angioedema matters a lot. Doctors look at symptoms and history to figure out the cause. This helps in choosing the best treatment.
| Angioedema Type | Underlying Mechanism | Clinical Features | Treatment Approach |
|---|---|---|---|
| Hereditary Angioedema | C1-inhibitor deficiency or dysfunction | Recurrent edema in various body parts | C1-inhibitor concentrates, bradykinin receptor antagonists |
| Acquired Angioedema | Autoantibodies or other factors disrupting bradykinin regulation | Associated with underlying conditions | Treat underlying cause, bradykinin-targeted therapies |
| ACE Inhibitor-Induced Angioedema | Inhibition of enzymatic degradation of bradykinin | Side effect of ACE inhibitor medications | Prompt discontinuation of ACE inhibitor |
| Histaminergic Angioedema | Mast cell degranulation and histamine release | Often associated with urticaria | Antihistamines, trigger avoidance |
| Nonhistaminergic Angioedema | Other mechanisms, such as bradykinin | Distinct clinical characteristics | Targeted treatment approaches |
Knowing what causes angioedema helps doctors treat it better. They can offer more targeted care this way.
Diagnosis of Angioedema
Diagnosing angioedema is mainly about how it looks and what patients tell their doctors. It’s important to tell apart the types that need different treatments. Tests help confirm the diagnosis and find what’s causing it. Doctor’s also look at different conditions to make sure they don’t miss anything.
Diagnostic Criteria
To diagnose angioedema, doctors look at sudden swelling that doesn’t go away when you press it. This can come with or without itching or pain and lasts from a few hours to days. The swelling might come back sometimes and its severity can change.
Doctors also check if there’s urticaria (hives) with the swelling. It’s important because treatment can be different if there are no hives. So, telling apart these two is key.
Differential Diagnosis
It’s vital to not only look at angioedema but also similar conditions. This makes sure the right treatment is given. Some issues that look like angioedema are allergic reactions, cellulitis, and more. A full check of a patient’s history and tests can help figure out the exact problem.
Diagnostic Tests
Diagnosis often happens after a doctor’s look but tests can support it further. Some tests include blood work, finding levels of certain proteins, and tests for allergies. These tests help pin down the type of angioedema and what might be causing it.

Treatment of Angioedema
Angioedema treatment depends on why it happens and how bad the symptoms are. People use different treatments, including ones they take when they need them or ones they use every day. Some medicines focus on specific kinds of swelling and have helped a lot.
On-Demand Treatment
On-demand treatment helps when the symptoms show up suddenly. It usually means taking antihistamines and corticosteroids. Antihistamines lower the body’s allergic reactions, which can stop swelling and itching. Corticosteroids bring down inflammation rates.
Prophylactic Treatment
Some folks may need regular treatment even if they’re not currently having symptoms. This type helps prevent attacks or makes them less severe. What people take every day depends on the kind of angioedema they have and what’s causing it.
There are a few common preventive treatments:
- Attenuated androgens
- C1-inhibitor concentrates
Attenuated androgens are hormones that calm the immune system, which can make attacks less often. C1-inhibitor concentrates work for angioedema that’s because of bradykinin, by balancing the C1-inhibitor level in the body.
Targeted Therapies
New treatments are focusing in on specific types of angioedema. For example, for swelling caused by bradykinin, bradykinin receptor blockers seem to do well. These drugs stop bradykinin from causing more swelling.
Another targeted option is using C1-inhibitor concentrates. These can replace what’s missing in people with hereditary angioedema.
Specific guidelines and rules apply to each targeted therapy. Talking to a doctor can help choose the right treatment route.
Emerging Treatment Options
Scientists are looking into new ways to treat angioedema. They’re studying DNA and CRISPR technology. These methods might offer more custom care.
| Treatment Option | Indication | Mode of Action |
|---|---|---|
| Antihistamines | On-demand treatment | Block histamine receptors to reduce allergic response |
| Corticosteroids | On-demand treatment | Reduce inflammation |
| Attenuated Androgens | Prophylactic treatment | Regulate immune response to reduce the frequency of attacks |
| C1-Inhibitor Concentrates | Prophylactic treatment, bradykinin-mediated angioedema | Restore C1-inhibitor balance, block bradykinin effects |
| Bradykinin Receptor Antagonists | Targeted therapy, bradykinin-mediated angioedema | Block bradykinin receptor to prevent attacks |
Management of Hereditary Angioedema
Hereditary angioedema (HAE) needs both long-term and short-term strategies to manage it. These include regular medications to prevent attacks and treating the sudden swelling when it happens. The goal is to lower how often the attacks occur and make them less severe. This way, the patient feels better overall.
Prophylactic Treatment
Preventing angioedema attacks is key in managing HAE. The right prevention method varies from person to person. Main prevention methods include using medications called C1-inhibitor concentrates and attenuated androgens.
C1-inhibitor concentrates like Berinert® and Cinryze® are given through a vein. They make up for the missing protein that causes the swelling. By doing this, they lessen how often and how bad the attacks are.
Attenuated androgens are pills that can help too. They boost the C1-inhibitor levels in the body, also reducing the number and harshness of attacks. But, they can cause side effects in some patients, so these might not be for everyone.
Acute Attack Treatment
Quickly treating an HAE attack helps a lot. It stops the swelling from getting worse and makes the patient feel better fast. The usual way to do this is with a special kind of medication called C1-inhibitor replacement therapy.
C1-inhibitor replacement therapy: Drugs like Firazyr®, Takhzyro®, and Haegarda® are used as injections. They stop a chemical called bradykinin from causing more swelling. This quickly improves the patient’s symptoms.
Disease Monitoring
Regularly checking the HAE status is important. It tells the doctor how well the treatment is working and if any changes to the plan are needed. This involves seeing the doctor often and maybe doing some tests.
Tests check things like the level of C1-inhibitor in the blood. They look at the patient’s symptoms too. This way, the doctor can tell if the treatment needs to be changed. The goal is to always give the best care so the patient can manage their HAE well.
Controlling HAE means using both prevention and quick-treatment methods. Preventing attacks with special medications and treating sudden swelling are both important. Keeping a close watch on the disease helps make sure the treatment is always right for the patient. This helps everyone with HAE live a better life.
Special Considerations in Angioedema Management
Managing angioedema involves special considerations for certain people. This includes kids, pregnant or nursing women, and the elderly. Careful attention is needed to safely and effectively treat angioedema in these groups.
Pediatric Management
Kids with angioedema might need different treatments. You must think about their age and size to choose the right care. It’s vital to keep an eye on how they’re doing and see the doctor regularly to adjust their treatment.
Management in Pregnancy and Breastfeeding
For angioedema in pregnant or nursing women, the safety of both mom and baby is key. Medicines chosen must be safe for the unborn child or the baby getting breastmilk. Doctors and patients should work closely to decide on a care plan that’s safe and effective.
Management in Elderly Patients
If an older person has angioedema, their other health issues must be considered. The doctor must be careful to pick medicines that won’t make other health problems worse. They will need to be checked and possibly have their care adjusted regularly.
Special care is crucial when treating angioedema in different groups, like kids, expecting or nursing moms, and the elderly. Adjusting treatment to meet their specific needs helps ensure they get better safely. This approach boosts their quality of life while dealing with angioedema.
Emerging Therapies for Angioedema
