Urticarial Vasculitis: Symptoms, Causes, and Management
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
TL;DR
Urticarial vasculitis is a rare autoimmune condition marked by itchy, painful hives caused by inflammation of the blood vessels. It usually affects only the skin, but it can also involve the joints, heart, kidneys, eyes, and lungs. There is no cure, but medicines that reduce inflammation can manage symptoms, and some people go into long remission. Long-term follow-up with a specialist, usually a rheumatologist, is important.
Quick Answer
What is the main symptom? Itchy, painful, swollen hives (urticaria) that come in episodes.
What is the root cause? Autoimmune inflammation of the blood vessels (vasculitis). Some cases have no identifiable cause.
What can trigger it? Infections (such as hepatitis B and C, mono, COVID-19, and Lyme disease), other autoimmune diseases, some medications, and some types of cancer.
Who is affected? Most common in adults over 30; women are more than twice as likely as men to develop it.
Which specialist? Usually a rheumatologist.
What is the treatment goal? Manage symptoms and prevent organ damage. There is no cure, but some people reach remission.
What the research says
Biologic drugs helped many people whose urticarial vasculitis did not respond to standard treatment. In a retrospective European study of 41 patients (52 treatment sequences with rituximab, IL-1–targeted therapy, or anti-IgE therapy), skin response after a median 25 months was complete in 40%, partial in 37%, and inadequate in 23%. Serious adverse events, mainly infections, occurred in 17% of patients. (Maisonobe et al., Rheumatology, 2025)
In a small case series, antihistamines alone did not clear the disease. Among 11 patients at one dermatology unit in Rome (91% women; mean age at diagnosis 52.8 years), none achieved complete remission on antihistamine monotherapy, while systemic corticosteroids gave rapid control in acute phases. The authors found that no treatment worked for everyone. (Artosi et al., J Clin Med, 2025)
What Is Urticarial Vasculitis?
Urticarial vasculitis is a rare form of vasculitis, in which the immune system mistakenly attacks the body’s own blood vessels. In vasculitis, the blood vessels swell and stretch, which makes it harder for blood to flow through them. The most visible result is urticaria, the medical term for hives: raised red or discolored bumps (welts) on the skin. These hives are not typical allergic reactions. They are often painful as well as itchy, and individual lesions usually persist for 24 hours or longer.
The skin is the most common site of involvement, but the inflammation can also affect blood vessels connected to the joints, heart, kidneys, eyes, and lungs. Because of this potential, urticarial vasculitis calls for careful evaluation and long-term follow-up.
What Are the Symptoms of Urticarial Vasculitis?
Most people with urticarial vasculitis have periods of symptoms that come and go, called episodes. The most common symptom is hives anywhere on the body. They are usually swollen, raised, red or discolored, itchy, and painful. After an episode ends, the skin where the hives were may look bruised or discolored. Some people also have angioedema, which is swelling in the tissue under the skin.
Severe symptoms are rare, but they can involve other parts of the body:
System affected | Potential symptoms |
Skin | Painful hives, bruise-like discoloration after episodes, angioedema (deeper swelling) |
Joints | Joint pain |
General | Fatigue, fever, and swollen lymph nodes |
Internal organs | Abdominal pain, kidney pain, shortness of breath, or red eyes |
Emergency warning: Go to the emergency room or call your local emergency number if you have trouble breathing, signs of a heart attack, or vision loss, as these can mean life-threatening organ involvement.
What Causes Urticarial Vasculitis?
Experts are still working to understand exactly what causes urticarial vasculitis, but it is classified as an autoimmune disease: the immune system, which normally protects the body from germs, accidentally attacks healthy blood vessels. Some people develop it with no clear cause (idiopathic). In others, it follows a condition that causes inflammation in the body, called a trigger.
Common Triggers and Risk Factors
Infections: Hepatitis B and C, mononucleosis (mono), COVID-19, and Lyme disease.
Autoimmune diseases: Any autoimmune disease can trigger it, especially rheumatoid arthritis, lupus, Sjögren’s syndrome, and hypothyroidism.
Other factors: Side effects of some drugs and medications, and some types of cancer.
Anyone can develop urticarial vasculitis, but it is more common in adults older than 30, and women are more than twice as likely as men to develop it.
How Is Urticarial Vasculitis Diagnosed?
A healthcare provider will look at your skin and ask about your symptoms. Diagnosis is usually part of a differential diagnosis, meaning tests are used to find out what is causing your symptoms before urticarial vasculitis is diagnosed. A rheumatologist — a specialist in inflammatory diseases — is usually involved, and a pulmonologist may be consulted if breathing is affected. Tests may include:
Skin biopsy: A small sample of a hive is examined under a microscope for signs of blood vessel inflammation.
Blood tests: To look for markers of autoimmune activity or inflammation.
Organ function tests: To check whether the inflammation has affected the kidneys, lungs, or other organs.
Treatment and Management Options
There is no cure for urticarial vasculitis, but treatment can manage symptoms. Your provider will suggest medicines that reduce swelling to relieve hives and inflammation, and which ones you need depends on your symptoms and any other health conditions you have. Some people eventually go into remission — long periods, usually months or years, between episodes — but a new episode is always possible.
Medication | Purpose |
NSAIDs | Over-the-counter drugs such as ibuprofen, aspirin, or naproxen to reduce pain and swelling |
Corticosteroids | Strong anti-inflammatory drugs |
Antihistamines | Commonly used for the itching of hives |
Immunosuppressants | Medicines that calm the overactive immune system |
ACE inhibitors | Another medication your provider may include in a treatment plan |
Ask your provider about side effects and which signs of complications to watch for. Tell them about all your other health conditions and medications, because these can affect which treatments will work for you. Monitoring your symptoms and keeping track of changes helps you recognize early signs of an episode.
The Bottom Line
Urticarial vasculitis is a rare, long-term condition. Most people only have skin symptoms, and medication can manage them, but when other organs are involved the damage can be life-threatening. Recognizing the signs of an episode, following a specialist-led treatment plan, and keeping up regular check-ups give you the best chance of catching internal involvement early.
Take the Next Step
See a healthcare provider if you have hives that do not go away or get better within a few days, or if your episodes become more severe or more frequent. Go to the emergency room right away if you have trouble breathing, signs of a heart attack, or sudden vision loss.
Frequently Asked Questions
Is urticarial vasculitis contagious?
No. Urticarial vasculitis is an autoimmune condition, so it cannot be spread from person to person.
How long do the hives last in urticarial vasculitis?
Unlike common hives, which often fade within hours, individual hives in urticarial vasculitis typically last 24 hours or longer, and the skin may look bruised or discolored after they fade.
What is the difference between hives and urticarial vasculitis?
Urticaria is the medical term for hives. Urticarial vasculitis is a form of vasculitis — inflammation of the blood vessels — that causes hives. Its hives tend to be painful as well as itchy, and they last longer.
Who gets urticarial vasculitis?
Anyone can develop it, but it is more common in adults older than 30, and women are more than twice as likely as men to develop it.
What can trigger urticarial vasculitis?
Triggers include infections (such as hepatitis B and C, mononucleosis, COVID-19, and Lyme disease), other autoimmune diseases (such as lupus, rheumatoid arthritis, Sjögren’s syndrome, and hypothyroidism), some medications, and some types of cancer. Some people have no identifiable trigger.
Is there a cure for urticarial vasculitis?
No. There is no cure, but some people eventually go into remission — long periods, usually months or years, between episodes. Even in remission, a new episode is still possible.
Can I take antihistamines for the itching?
Antihistamines are one of the medications providers may use. In a small case series of 11 patients, none reached complete remission with antihistamines alone, so a stronger plan is often needed. Your provider will guide treatment.
Is urticarial vasculitis life-threatening?
Most people only have skin symptoms, but when it affects other organs, such as the heart, lungs, or kidneys, the damage can be life-threatening. Go to the emergency room if you have trouble breathing, signs of a heart attack, or vision loss.
Does it always affect the kidneys?
No. It usually affects only the skin, but it can involve the kidneys, joints, heart, eyes, and lungs, which is why your provider may order organ function tests and regular follow-up.
Can I get urticarial vasculitis after COVID-19?
It is possible. COVID-19 is listed among the infections that can trigger urticarial vasculitis.
Can urticarial vasculitis be prevented?
No. Because experts do not know exactly what causes it, there is no known way to prevent it.
How rare is urticarial vasculitis?
It is rare. Experts are not sure how many people have it, partly because many people with mild symptoms never get a diagnosis.
