Skin Allergy

Overview of skin sensitivity

Skin Allergy can be caused by a variety of factors. These disorders include the immune system, drugs and infections. When the allergen is responsible for stimulating the response of the immune system, it is a delicate skin condition.

Atopic dermatitis (eczema)

Eczema is the most common skin condition, especially in children. One out of every five children affects only one in 50 adults. It is now believed that the reason is the “leakage” of the skin barrier, which makes it dry and becomes susceptible to irritation and inflammation due to many environmental factors. Also, some people with eczema have a nutritional allergy which can increase the symptoms of eczema. In about half of patients with severe atopic dermatitis, the disease is due to defective gene inheritance in their skin called filaggrin. Unlike hives, eczema itching is not caused only by histamine, so antihistamines may not control the symptoms. Eczema is often associated with asthma, allergic rhinitis (hay fever) or food allergies. This arrangement of progress is called the Atheist Process.

Allergic allergic dermatitis

Allergic contact dermatitis occurs when your skin comes into contact with an allergen. For example, if you are allergic to nickel and your skin touches jewelry made even with a very small amount of nickel, you may get red, rough, scaly, scaly or swollen skin at the contact point.

When contact with poison ivy, poisonous oak and poisonous sapas can also cause allergic contact dermatitis. Red rash and itching are caused by greasy coating covering these plants. An allergic reaction can come from touching it physically, or by touching clothing, pets, or even gardening tools that touch the oil.

Urticaria (hives)

Hives are inflammation of the skin’s output when the immune system releases histamine. This causes small blood vessel leakage, resulting in swelling of the skin. Swelling is called in the deep layers of the skin and vascular edema. There are two types of acute and chronic urticaria. Acute urticaria occurs sometimes after eating a particular food or by contacting a particular stimulant. It can also be caused by non-allergenic causes such as heat or exercise, as well as medications, foods, insect bites or infections. Chronic urticaria is rarely caused by specific stimuli, so sensitivity tests are usually not helpful. Chronic urticaria can last for months or years. Although they are often uncomfortable and sometimes painful, the hives are not contagious.

Edema and vascular swelling in the deep layers of the skin. It is often seen along with urticaria (hives). Vascular edema occurs several times in soft tissues such as the eyelids, mouth, or genitals. Vascular edema is called “acute” if the condition continues for a short period such as minutes to hours. Acute vascular edema is usually caused by allergies to medications or foods. Chronic recurrent angioedema is when the condition returns over a long period of time. It usually does not have a specific reason.

Hereditary angioedema (HAE)

Genetic hereditary edema (HAE) is a rare but serious genetic condition that involves swelling in various parts of the body including the hands, feet, face, intestinal wall and airways. Does not respond to antihistamine or adrenaline therapy, so it is important to go to a specialist.

Dermatology is one of the most common forms of allergy that is treated and managed by an allergist / immunologist, a doctor with specialized training and specialized expertise in accurately diagnosing your condition and relieving symptoms.


Itching, redness and swelling are common in most skin allergies. However, there are some differences that help diagnose certain cases.

Atopic dermatitis (eczema)


Itchy, red or dry skin. May “cry” or leak the fluid that spreads the crusts when scratched, which means that it is also infected.

In infants, eczema often appears on the face. Children are prone to rashes when bending the elbow, wrists, behind the knees and behind the ears. Adolescents and young people usually get rashes in the same places as children, as well as on hands and feet.

Patients with false filaggrin genes often have hand eczema with excessive small lines on the palm skin.


epends on the regular use of the moisturizer and topical medications to reduce inflammation. One such treatment is topical steroids. In children where the skin is bleeding and sores, the infection that needs antibiotics may be the main cause.

Babies and young children with severe eczema should be evaluated for food allergies. It is important to see the allergen / immunologist for diagnosis and management. Often there is a need to receive input from a dietitian as well.

Food allergies that cause eczema are less common in older children and adults. If you suspect that you have eczema caused by food allergies, a confirmed diagnosis requires avoiding the intake of radioactive food for four weeks with the help of a nutritionist before you have a dietary challenge under your doctor’s supervision to ensure that the food is actually causing the food. Glow.

Urticaria (hives) and angioedema

Skin Allergy


The urticaria is a itchy or red and white bumps raised, ranging in size and can appear anywhere on the body. Vascular edema on the face often appears around the eyes, cheeks or lips. This deep swelling can also occur on the hands, feet, genitals, or inside the intestine or throat. In acute urticaria, scars disappear within minutes to a few weeks. Chronic bee hives last for months or even years.


In most chronic cases, the exact cause can not be determined. Routine tests such as blood counts or general monitors are not cost-effective, and these tests do not make a difference in treatment strategies to relieve symptoms. There are some cases where the sensitivity test is useful, especially when eating a particular food or contact with a particular substance that leads to the appearance of severe bee hives.


Skin Allergy

Atopic dermatitis (eczema)

Eczema is sometimes described as “itching.” The skin rash is the result of scratching, the more scratched the patient increased the severity of the rash. For this reason it is important to avoid scratching.

The most effective way to treat eczema is to use topical moisturizers and ointments, such as topical steroids, calcinurine inhibitors or phosphodiesterase inhibitor 4. Itching is not alleviated by antihistamines, although it is sometimes used at night to help people with eczema Sleeping. Dupilumab is an intravenous biological therapy used to treat adult patients with moderate to severe atopic dermatitis that is difficult to control.

Antibiotics may be prescribed if a bacterial infection is suspected in the skin as a stimulant of eczema. Symptoms include peeling, goose and pain. Oral steroids should be avoided, although they are effective, but eczema usually comes back when the medication stops. Oral stimulants can also cause serious side effects if taken for long periods of time.

Sometimes, cotton underwear and body suits help protect skin from irritants and scratching. Avoid using soap products containing sodium lauryl sulfate and any triggers causing a reaction. Your allergist will be able to determine if there is a preventable catalyst.

These strategies can treat and manage skin sensitivity alleviating social challenges as well. People with eczema, especially children, are sometimes ignored or discriminated against by others who believe that the rash is contagious.

Urticaria (hives) and angioedema

If the cause of the hives can be determined, you can manage the case by avoiding that trigger. Treatment of hives or vascular edema often works with antihistamines that control the itching and recurrence of the rash.

If the rash is not controlled by a standard dose of antihistamines, your doctor may suggest an increased dose to improve symptom control. If the antihistamines do not control the rash or if you leave bruises, it is important that your doctor rule out other causes that may need alternative treatments. Sometimes chronic hives without known cause may be resistant to antihistamines. Omalizumab is a biological treatment by injection that may be useful in such cases.

If you are taking some blood pressure medications (ACE inhibitors) and vascular edema, it is important to consult your doctor. Change to another blood pressure medication may help vascular edema.
