Allergic skin rashes in adults treatment. How to get rid of small rashes on the body? Drug therapy: drugs and application features

A rash on the body of an adult is a symptom of various skin diseases - from completely harmless teenage acne to severe and dangerous infections. Correct recognition of rashes helps to make a correct diagnosis, although most often it is not worth relying only on skin changes.

It should also be noted that it makes no sense to deal exclusively with the rash - first of all, it is necessary to treat the underlying disease, after which, after elimination, the rash goes away on its own.

An allergy is an atypical reaction of the body to an antigen that the immune system perceives it as a threat. Simply put, with allergies, the body reacts with a rash to contact with allergens that usually do not cause harm. healthy person. This can be animal hair, food, medicines, plant pollen and other provoking factors.

An allergic rash on the body of an adult is a rash like urticaria (red blisters similar to a nettle burn) and manifestations of eczema. Red, itchy rashes that cover the skin after contact with an allergen are defined as toxicoderma or contact dermatitis. It can occur separately from the rash or together with it. Photos of this phenomenon can be viewed in detail on numerous thematic websites on the Internet dedicated to allergic reactions.

Redness of the affected area of the skin, itching and painful sensations, sometimes - an increase in local and general temperature. Allergy rashes can vary in appearance and appear as small red blisters or spots that are grouped into small areas.

The distinctive feature is that allergic rash itchy, its appearance is accompanied by discomfort and irritation of the skin. At the same time, a rash on the body due to allergies is never purulent.

How to distinguish an allergic rash on the body of an adult from other types of rash?

First of all, pay attention to the provoking factor (allergen), after contact with which characteristic rashes appear on the skin. It can be contained anywhere - in food products, house or street dust, household chemicals, medicines. Most often, the connection between interaction with an allergen and the appearance of a rash can be traced even at home.
Secondly, they look at the appearance of the rash. In allergic reactions, a rash appears in spots or blisters, which extremely rarely takes the form of a pustule or nodule. But that doesn't mean it's harmless. Elements of the rash tend to merge and can cover large areas of the skin, causing irritation, itching, pain and other discomfort. However, itchy skin is not a characteristic sign of allergies, since it also appears with other types of rashes on the body of an adult.

Therefore, the fact that the rash itches and hurts cannot be considered reliable. diagnostic sign. Just as it should not be considered an unambiguous indicator allergic reaction the presence of symptoms of general intoxication - headache, catarrhal symptoms, fever, deterioration of health. A correct diagnosis can be made only after skin allergy tests are performed, which allow one to identify and identify the allergen - the provocateur.

Rash due to skin diseases

Skin diseases can manifest themselves in the most various types rash. It is extremely difficult for a non-specialist to diagnose the disease by rashes. The rash can be spotty, nodular, pustular, watery, and accompanied by various additional symptoms. To accurately make a diagnosis, it is necessary to conduct a series of specific tests to determine the causative agent.

Bacterial infections

The appearance of the rash depends on the nature of the disease. Bacterial skin infections are manifested by a pustular rash on the body and fever. Small pustules ripen on the skin, burst with the release of yellowish pus, and a small ulcer remains in their place.

The skin in the affected area is always inflamed and red (this is in contrast to acne and other non-infectious lesions). The shape of the pustules, the size and boundaries of the affected area can be a valuable diagnostic sign for a specialist.

Furunculosis. With furunculosis, many painful ulcers appear on the body. The causative agent of the disease is staphylococcus. The inflammatory element matures for quite a long time, after which it is opened with the release of purulent contents; in its place there remains a rather deep wound, which, if properly treated, soon heals. After large boils resolve, scars may remain on the skin.

Fungal infections

Fungal infections do not appear as a pronounced rash. Instead, an area of redness and flaking of the skin forms on the skin, painful to the touch. Such a rash on the body of an adult itches, itches and causes significant discomfort.

There may be no symptoms of general intoxication. Characteristic fungal skin lesions - they are located mainly in the folds of the skin, between the fingers, under the breasts in women, in the groin, in the fold of the abdomen in obese people, on wound surfaces.

A common feature of fungal and bacterial skin diseases is that the affected area tends to spread and expand. If left untreated, the process quickly progresses and invades more and more areas of the skin.

In addition, the course of such infections is accompanied by a gradual deterioration of the patient’s condition. Common fungal skin infections include:

Pityriasis rosea. The course of the disease is accompanied by the appearance of round or oval pink spots with peeling in the center and a characteristic red ridge around the perimeter. The rash quickly spreads throughout the body, itching and itching.
Lichen planus. Accompanied by the appearance of nodular elements, which are arranged symmetrically and grouped into lines, rings or garlands. An itchy rash most often appears on the torso, limbs, or genitals.

Viral infections

Viral diseases can also manifest as skin rashes. The most common of them are and. The human papillomavirus exists in many types (more than 50), differing in their danger to the human body.

Papillomatosis is manifested by the appearance of warts and papillomas on the skin. The affected area may be different, the papillomas themselves do not cause discomfort, do not hurt or itch, but their main danger is that under certain conditions they can degenerate into malignancy. Therefore, experts advise getting rid of such tumors as soon as possible.
Shingles. The appearance of watery, painful blisters is caused by a herpes virus. They are located on the back or lower back along the nerve fibers. After opening, small erosions remain in place of the bubbles, which soon dry out and become crusty.
Herpes is another common viral disease, affecting the skin and nervous system. A herpes rash most often appears on the skin and red border of the lips, oral mucosa, and less often on the genital area (genital herpes).

The appearance of rashes is provoked by microtraumas, hypothermia, and other unfavorable factors. The pathogen itself remains in the patient’s blood throughout his life. First, painful watery blisters appear in the affected area, which after a while are opened and the contents are released. In their place, small ulcers remain, which soon become covered with a dry crust.

Accurately determine the nature skin infection Only a doctor can do this after appropriate tests to identify the pathogen. Despite the extremely unpleasant symptoms, such diseases quite rarely turn out to be dangerous to the patient’s health; correct treatment.

Non-infectious skin lesions

There are also non-infectious lesions skin, manifested by the appearance of a rash. The most common of them is acne.

And red pimples are pustular disease, which has a very limited area. Unlike bacterial skin lesions, the area affected by acne does not tend to spread. Their appearance is associated with dysfunction sebaceous glands which begin to produce excess sebum, clogging the pores. If skin care is not carefully taken care of, pathogenic bacteria begin to multiply in clogged sebaceous ducts, and an inflammatory process develops, ending in the formation of acne.

Skin pigmentation defects, such as vitiligo or solar keratosis, can also be considered a manifestation of the rash. They are most often not dangerous to health if you consult a doctor in time and take curative measures. But when they are exposed to unfavorable factors, there is a risk of developing malignant neoplasms.

Rash when intestinal infections

Some intestinal diseases manifest themselves as skin rashes. For example, when typhoid fever A very characteristic type of rash appears - roseola. They are a red rash on the body of an adult or child, looking like small mesh formations. When you press them, roseolas disappear, then appear again. Roseola rash is an important diagnostic sign of typhoid fever.

The appearance of a rash in other intestinal infections does not have such pronounced specificity. Unlike typhus, for other diseases digestive system the rash is not a valuable diagnostic sign; intestinal symptoms, in particular the features of stool disorders, are much more important.

Rash on the body in adults with chronic diseases

It is the rash on the skin that can be the first sign prompting the patient to see a doctor when he otherwise feels completely healthy. Such manifestations are characteristic of syphilis, tuberculosis, and systemic lupus erythematosus.

The disease lasts a long time, throughout the patient’s life, and is characterized by alternating periods of remissions and severe exacerbations. There is no medicine that can completely get rid of SLE; therapy is aimed only at prolonging remission and alleviating existing symptoms.

The skin manifestations of lupus appear as painless or moderately painful, itchy red patches that form the affected area characteristic shape. On the face, they are grouped on the cheekbones, cheeks and bridge of the nose, forming a “butterfly” shape; less often, rashes affect the neck and scalp heads.

Syphilis. Rashes with syphilis usually occur at the secondary stage of the disease; they can be different in appearance, but most often they have the characteristic appearance of syphilitic gummas - large single formations that appear on various areas of the skin. Over time, they open with the formation of deep ulcers, in place of which, as they heal, rough scars form, disrupting the appearance of the skin and affecting the mobility of facial muscles.

Psoriasis, although it has mainly skin manifestations, is not exclusively skin disease. This is a chronic disease that affects the skin, connective tissue, joints. It is impossible to completely get rid of psoriasis, but therapy can reduce the severity of the disease and prolong periods of remission. Skin manifestations of psoriasis look like small red papular formations that are covered with gray scales on top. As the disease progresses, the number of papules increases and they merge into large plaques that can affect large areas of the skin.

Other types of rash in adults

Some types of rash can be caused by various factors that are not signs of disease. For example, these include skin irritation caused by short-term adverse effects. As a rule, in such cases there is a fairly clear connection, and the causes of the rash are not allergens (insect bites, touching poisonous or burning plants).

The so-called nervous rash on the body of an adult is a manifestation of atopic dermatitis. This is a chronic disease that can occur with varying intensity. The cause of exacerbation can be various factors, including stress and increased emotional stress. In such cases, the rash appears within 24 hours after the patient has experienced a nervous shock.

Chemistry.
Cosmetics.
Medications.
Food.
Personal hygiene products.
Pet fur.
Pollen.

The mechanism of skin allergies

The main factor in the manifestation of allergic dermatosis is considered to be any allergen- a substance with a molecular structure that is of protein origin.

It happens that allergens can be various elements that do not provoke an immune response when they penetrate the blood. Particles that are carried by antigenic determinants are called haptens. These elements can bind to tissue proteins. Haptens are found in medications and other chemicals.

If an allergen or irritant enters the human body, sensitization begins to develop, which subsequently leads to excessive sensitivity of histamine receptors. This action is explained by the formation of antibodies or the synthesis of sensitized leukocytes.

An allergic rash on the skin of an adult forms at the stage of pathophysiological development of the disease. At this time, mediators of the pathological process are able to affect normal skin cells, provoking an inflammatory process.

Itching

In most cases skin allergy may be accompanied by itching of varying intensity. The main causes of itching are external and internal allergens.

The body begins to perceive such allergens as dangerous, which results in an allergic reaction in the form of itching. There are several main allergic skin diseases that can be accompanied by itching. These diseases are described below.

There is a large group of diseases that have similar clinical symptoms- allergic urticaria.

A third of the world's population has experienced manifestations of this disease at least once.

What is this

At allergic urticaria blisters appear on the skin that resemble a nettle burn, causing itching and burning.

A feature of the mechanism of development of the disease is immediate hypersensitivity.

Once an allergen enters the body, the reaction develops very quickly. The disease is not contagious.

Causes

The human body can react differently to certain substances.

Approximately 75% of patients suffering from this type of allergy develop an acute form of the disease.

Depending on what exactly stimulates the production of mast cells, immune and non-immune forms of nettle fever are distinguished.

In the acute form, the immunological mechanisms of the occurrence of the rash dominate, while in the chronic form, the mechanism of activation may be different.

Etiological factors that provoke urticaria are divided into:

to exogenous (physical) factors. These include mechanical, temperature, food, and medicinal provocateurs;
to endogenous factors. These are somatic diseases and pathological processes internal organs. The cause of an allergic reaction in this case may be cholecystitis, pancreatitis, lupus erythematosus, gout, diabetes mellitus, tumors various localizations, hormonal fluctuations.

Acute

In acute nettle fever, after contact with the allergen, a rash appears quickly. It looks like small or large blisters, red in color with a bright edging.

The rash may appear in small areas in the form of spots.

Most often they are localized on the skin, but sometimes they can also be observed on the mucous membranes.

The rash disappears within twelve hours.

From time to time it may appear in new areas of the skin. In general, the disease lasts up to six weeks.

Chronic

Chronic or recurrent urticaria. The illness lasts more than six weeks and can last for three to five years.

In half of the cases, the rashes reappear after a long remission.

More often women suffer from this disease.

There are chronic persistent urticaria, in which the rash is constantly renewed, and chronic recurrent urticaria, manifested in the form of exacerbations after certain periods of time.

Pseudo form

Pseudoallergic urticaria is not an independent disease, but a symptom indicating problems in the digestive organs.

It occurs when:

chronic gastritis;
hepatitis;
infectious diseases;
helminthiasis;
or is a consequence of poisoning.

It differs from allergic form disease in that the immune system does not take part in the formation of mediators of its occurrence.

Types of hives allergies

There are the following types of urticaria:

acute;
chronic;
subacute;
chronic recurrent.

Acute

Acute urticaria develops as an allergic reaction to medications, foods, viruses or insect bites.

Most often it occurs on the skin of the extremities and torso and is accompanied by severe itching, which intensifies in warmth and hyperemia that occurs 15-20 minutes after contact with the allergen.

Acute urticaria begins suddenly, and the rash can disappear just as quickly, leaving virtually no traces.

Giant form or acute limited angioedema

Nettle fever or Quincke's edema is an allergic reaction of the body to any irritant.

It manifests itself in the form of blisters, which can reach large sizes.

Most often observed on the face in the area of the lips, eyes or mucous membranes. With sudden swelling of the skin, large nodes form.

Sometimes it can cause swelling of the arms, legs, or genitals.

Nettle fever can block the airways, causing asphyxia, in which case it poses a threat to human life. The swelling disappears within a day or several hours.

Persistent papular

Papular urticaria develops due to long-term treatment any type of urticaria.

It is accompanied by the formation of papular blisters, due to the fact that a cellular infiltrate is added to the existing edema.

The blisters rise above the surface of the skin, and the tissue underneath them swells.

The disease can last for months and progress, accompanied by severe itching and hyperpigmentation, due to which some areas of the skin acquire a dark tint.

Chronic relapsing

This type of disease is characterized by a wave-like course.

The disease can last up to twenty years, with periods of stable remission occurring.

Urtricarial elements transform into papular elements quite rarely.

It is often accompanied by Quincke's edema.

This form of allergic reaction is characterized by particularly severe itching. Often, patients suffering from the disease scratch their skin until it bleeds.

The scratches may become infected and a secondary infection may occur.

Solar

The cause of the disease is ultraviolet radiation, but its occurrence is also associated with porphyrias of various origins And chronic diseases liver.

It appears on exposed areas of the body, in the form of rashes and blisters that appear within ten minutes after exposure to the sun.
