Who Might Get Contact Dermatitis

People who work in certain professions have a higher risk of developing contact dermatitis. You might repeatedly encounter irritating chemicals or allergens in these professions:

What Causes A Rash In Rheumatoid Arthritis
Eczema, Sweet’s syndrome, and pyoderma gangrenosum are all related to autoimmune problems. Both Sweets syndrome and pyoderma gangrenosum are neutrophilic dermatoses, inflammatory skin conditions related to an overload of a type of white blood cell called neutrophils. Neutrophils naturally produce an inflammatory response to infection. In an autoimmune condition, the skin may be attacked as foreign by the immune system, leading to neutrophils overwhelming the skin and causing inflammation as if the skin was infected.
While the precise cause of eczema is not known, it is generally considered to be an autoimmune response that causes inflammation of the skin. Other autoimmune conditions besides RA have been associated with eczema, including Crohns disease and ulcerative colitis.
Rheumatoid vasculitis is caused by inflammation of both small- and medium-sized blood vessels, often as part of an RA flare-up. It usually occurs in people who have had severe RA for more than 10 years. Certain factors play a part in those who are at higher risk for this complication. Most people who develop rheumatoid vasculitis have a high rheumatoid factor in their blood and many smoke cigarettes.
Palmar erythema, reddening in the palms, has a wide variety of causes. When someone with RA experiences red palms, however, it is most likely to be as a result of an autoimmune response. It can also be caused by medication taken to treat RA.
Eczema Or Herpes: How Can You Tell The Difference
Its often easy to distinguish between eczema and herpes because of their distinctly different symptoms. While herpes triggers defined blisters that burst and scab over, usually around the mouth or genitals, eczema causes rough, dry rashes in other areas of the body.
To distinguish between herpes and severe eczema that has produced open sores, consider the symptoms that occurred before the sores appeared and the location of the sores.

There isnt a test for irritant contact dermatitis. Your healthcare provider may be able to determine whats causing the rash based on the types of irritants or chemicals youre exposed to regularly.

What Is Dermatitis And What Does It Look Like
Dermatitis is a word used to describe a number of skin irritations and rashes caused by genetics, an overactive immune system, infections, allergies, irritating substances and more. Common symptoms include dry skin, redness and itchiness.
In the word dermatitis, derm means skin and itis means inflammation. The word as a whole means inflammation of the skin. The rashes range from mild to severe and can cause a variety of problems, depending on their cause.
Dermatitis causes no serious harm to your body. It is not contagious, and it does not mean that your skin is unclean or infected. There are treatment methods and medications that can manage your symptoms.
How Is Dermatitis Diagnosed
Your healthcare provider will take a close look at your skin. They will look for classic signs of dermatitis such as a rash, redness, scales, dryness and more. They will ask about the symptoms youre experiencing. Are you itchy? Does your skin feel like its burning? Is your skin dry? Have you come into contact with anything that might irritate your skin?

What Are The Complications Of Contact Dermatitis
Allergic contact dermatitis is a Type IV hypersensitivity reaction, caused by a different immunologic mechanism than hives, angioedema, or anaphylaxis. However, very rarely, patients may have immunologic dysfunction which results in multiple types of concurrent hypersensitivity reactions. Thus, it is possible that people with contact dermatitis can develop hives and swelling after coming into contact with an allergen. Hives are red, raised, itchy skin welts. Angioedema is swelling deep under the skin.
Extremely rare, allergic contact dermatitis can overlap with a severe, life-threatening allergic reaction called anaphylaxis that can swell airways and close them. If you think you are experiencing anaphylaxis, call 911. Youll need an immediate epinephrine injection to counteract this allergic response. People with known allergies can carry an EpiPen®, a brand of injectable epinephrine.
What Causes The Inflammation
So, what causes your skin to break out in red, itchy patches? Experts arenât exactly sure. But research says things like health, genetics, environment, certain products, and lifestyle may act as triggers. But eczema affects different people in different ways, so the things that cause you to have flare-ups may not bother someone else.
Immune system. When you have eczema, your body has an immune system that reacts too much. It responds easily to something thatâs either inside your body such as genes or outside of it like an allergen or irritant. This reaction damages the skin barrier — the topmost layer of your skin that defends your body from bacteria and keeps it from losing too much moisture. Without this protection, your skin is more sensitive, dry, brittle, and prone to inflammation.
Genetics. Youâre more likely to have eczema if you have:
Research shows that youâre also more likely to have eczema if you have a gene mutation that makes your body less able to produce enough filaggrin. This is a type of protein that helps your body build a strong skin barrier. If youâre low on filaggrin, your skin may lose a lot of water and become dry. It can also expose your skin to viruses and bacteria and make it more prone to infection.
Thereâs no cure or supplement you can take to fix your filaggrin levels, but keeping your immune system healthy can help ward off skin problems.
