Demodecosis: causes, symptoms and treatment

Skin diseases most often deliver a person only cosmetological discomfort. They rarely carry a serious threat to life. It is to such diseases applies demodicosis. Any parts of the body with sebaceous glands can be affected by this pathology. At the same time, the internal organs will not be affected by the infection. Despite the fact that for the life of demodicosis does not pose a threat, it should be treated immediately after detection.

The disease negatively affects the appearance of a person, as a result of which his self-esteem decreases. It begins to close on people, it becomes nervous and quick-tempered. To cope with the disease, you need to consult a doctor, confirm the diagnosis and receive the prescribed therapy.

What is demodicosis?

Demodecosis - This is a skin lesion with a microscopic mite. This tick is called Demodex. The demodex mite lives in the sebaceous glands, in the hair follicles, for this reason the places of its distribution are eyelids, face skin, area of ​​the eyebrows, forehead, nasolabial folds and chin, external auditory canal. Places with abundant sebaceous excretions are most favorable for tick habitats. In the body of a healthy person, Demodex mites can also live - in the skin, feeding on dead cells. However, in order to penetrate into the deep layers, they need to wait for the weakening of immunity, after which they cause an inflammatory process.

Demodecosis in its manifestations is very similar to rosacea and acne. Very often, these diseases are combined, because common and rosacea suppress the natural protection of the skin.

About 97% of people suffer from this parasite. It was this percentage that was allocated to Chinese scientists during the study, in which more than a million people of different ages, nationalities, occupations and sectors of society took part. The study took an average of about fifty years.

By their naivete, people do not even think about such a neighborhood, although there is a malfunction in the body, and ticks “attack”.

Men suffer from demodicosis two times less often than women, and women with white, tender skin. The reason for the development of this disease may be: a failure of the endocrine and digestive systems, stress, reduced immunity, and the use of expensive cosmetics with hormonal or other biological additives. Peaceful life with a tick can disrupt the excessive use of black coffee, alcohol, spicy seasonings, prolonged stay at the computer, frequent visits to the bath or tanning beds.

If there was an opportunity to look into the hair follicles from which the hair grows, or into the glomeruli of the sebaceous glands located right there, then one would consider small, colorless, bristled "worms". This is exactly what mites from the Demodex family look like.

Tick ​​is very easily detected in the laboratory, is carried out directly in the presence of the patient in the office. To do this, take 8 cilia from each eye - four from the upper eyelid, the same from the bottom. These cilia are placed on a glass slide, dripping an alkaline solution or a mixture of 1 ml of glycerol and 9 ml of saline. Next, cover with a veil and study the cilia under the microscope.

Who is the causative agent of demodicosis?

Demodecosis provokes tick. This microscopic organism is called Demodex Folliculorum / Breve (D. Folliculorum / brevis). The tick parasitizes the sebaceous glands of a person, in which there are favorable conditions for its reproduction. From animals, a person cannot become infected with a tick, it is transmitted only among a population of people. Ticks live on the skin of dogs and cats, but they cannot exist on the human body.

Demodecosis: causes, symptoms and treatment

The mite has mobility sufficient for a microscopic organism. It can move at a speed of 13-18 mm / hour. It is not difficult for him to navigate the skin and conquer new "areas" of habitat. Moreover, ticks migrate all the time and in large quantities, but it is impossible to notice their movements without a microscope. Therefore, it is very easy to get demodecosis, it is enough to use household items of an infected person or to contact them closely. The tick will quickly find a sebaceous gland and master it. It will exist in it until the patient receives treatment.

The tick can settle on the eyelids, in the armpits, in the perineum, that is, in those areas of the dermis where there are sebaceous glands. Therefore, the characteristic symptoms of infection will appear in these places. The optimal temperature for the existence of a tick is 37-40 degrees. He actively increases his number in hot climates and in warm rooms. In such conditions, demodicosis is manifested especially intensely.

Who can get demodecosis?

Statistics show that by the age of 30 about 60% of the population is infected with tick. In this case, the symptoms of the disease will appear only in some individuals. The parasite is activated when the human immune system fails. Tick ​​infestation does not lead to allergies or tissue damage if the body inhibits its activity.

Demodecosis: causes, symptoms and treatment

In people whose immune system is weakened, or there is a genetic tendency to hypersensitive reactions, demodicosis will manifest characteristic symptoms.

At risk are the following categories of citizens:

People with immunodeficient pathologies, for example, diabetes, HIV, tuberculosis, cancer.

People whose close relatives are infected with ticks and suffer from pronounced symptoms of pathology.

People who are regularly exposed to stressful factors.

People prone to allergic reactions.

People working in harmful enterprises.

In such patients, demodicosis appears vividly.

The first signs of demodicosis

Acne, juvenile acne, rash, pink acne, pustules, ulcers, etc., appearing on the face may indicate the presence of demodicosis. In disrepair, these acne cover the skin of the back, chest and hips;

red spots on the face;

very oily skin and enlarged pores. Areas affected by demodicosis look moist, greasy, have a characteristic luster. Particularly affected skin on the nose and cheeks;

skin of the face is bumpy. Inside the skin, a rough “scar” tissue and many small calcium lumps are formed, and this gives unhealthy complexion and hilly skin;

the nose grows in size, it happens that quite strongly: the nose becomes like a big blue-red plum (rhinophyma);

crawling, tickling, and itching. Very often, people do not pay attention to tickling at all, and automatically scratch it. By evening, the itch gets worse and continues to disturb throughout the night. This indicates the most active life activity of ticks and the time of their mating.

scalp itching, hair loss occurs. Early baldness can also talk about the vigorous activity of the Demodex mite;

itchy eyelashes. The loss of eyelashes, too, is most often the result of the vital activity of mite demodekoza living in the roots of eyelashes. At the base the eyelashes begin to itch, the eyelashes become thinner and fall out;

itchy ears

Demodecosis: causes, symptoms and treatment

Symptoms of demodicosis

Virtually any part of the skin with the exception of the feet and palms may be susceptible to infection. Eyelid demodicosis can cause severe eye allergy, which intensifies the symptoms of a lesion. This disease is called ophthalmodemodecosis.

Risk factors that can lead to activation of the disease:

Temperature changes. Therefore, demodicosis often makes itself felt in the fall and spring.

The weakening of the immune forces of the body. This occurs as a result of the influence of stress factors, chronic diseases, hormonal steroid drugs, etc.

Violation of personal hygiene. At the same time, the sebaceous glands become blocked, which causes the active reproduction of the tick.

Alcohol abuse, smoking.

Symptoms appear primarily in those areas of the body where there is a large accumulation of parasites. Localization of ticks can be the body, the eyelids, and the eyes.

Skin lesions

Occlusion of the sebaceous gland cannot occur asymptomatically. Often, signs of demodicosis appear on the face, on the back, and in the armpits (or popliteal fossae). In these areas of the body accumulates the maximum number of parasites.
