Psoriasis, the causes of which are unclear until today remains a mystery to scientists all over the world. The disease can develop suddenly, regardless of the age and sex of the patient.
There has recently been a primary development of psoriasis among women and children, without any precipitating causes. In rare cases, the disease can move on their own, but as a rule, to achieve long-term remission requires special treatment, and to recover the patient.
Theory of the origin of psoriasis
Among doctors and researchers there are several theories of developing the disease:
HEREDITARY. Genetic transmission of the disease is the most common, because doctors in the event that every other three noted the presence of psoriasis in history. Joining the precipitating factors, the first symptoms of disease appear inevitable. Usually, when you inherit, it is noted that the relationship between the sex of the children (the disease develops more often among same-sex relatives).
IMMUNE. The immune system theory of disease is considered to be its most important founders. Immune system components are present in almost every anti-inflammatory, immune-nature, in some cases, ease the symptoms of the disease.
However, in spite of a sufficient amount of research on the immune theory of psoriasis, triggered by its occurrence (triggering mechanisms) has not been fully elucidated. Therefore, preventive measures for disease development include, firstly, strengthen the immune system (in particular, women, the elderly and children) and protection of the skin (including the head) infectious diseases. It is the immune theory shows that the most serious complications: psoriatic arthritis (explains the causes of psoriasis on the elbows, knees and hands), and in some cases — the defeat of the spine.
NEUROLOGICAL. According to the theory of psychosomatic medicine, the disease can be due to malfunction of the nervous system, as a result of severe stress. In other words, the mental state of the patient reflects the state of the patient, which can lead to psoriatic arthritis symptoms hands, head, legs, etc. in addition, the factors that strengthen the development of the disease on the background of psycho-somatic medicine, has the positive effect of sedatives, which again refers to a spiritual cause psoriasis.
EXCHANGE. Studies do not rule out the development of the disease in connection with the violation of metabolism. As a rule, most patients experience hypothermia, which indicates a slowdown in metabolism. In addition, a violation of fat metabolism indicates elevated levels of cholesterol in the blood, and weakening of the immune system have been shown to reduce vitamins (A, b), as well as copper, iron and zinc detected in 2/3 of all cases.
4 in each case have diabetes, indicates a violation of carbohydrate metabolism, and the metabolic nature of the disease to confirm malfunction of the thyroid gland, the pancreas and the sex glands, despite treatment.
ALLERGIC. Proponents of this theory believe that the psoriatic arthritis symptoms occur as a result of allergies. This is supported by the fact that this disease, like Allergy, is not contagious and is very itchy rash on the skin. That's why psoriasis is very often prescribed antihistamines. In addition, it is similar to the symptoms of the allergic and psoriatic arthritis.
HORMONAL. This hypothesis is associated with the violation of hormonal background, which happens in the body (menopause, puberty, pregnancy, etc.). However, this trend did not become popular, because most patients psoriasis develops when hormonal "silence".
CATCHY. This theory of the origin of the disease is one of the most common. This causes the symptoms of psoriatic arthritis symptoms associated with different pathogens (spirochetes, streptococci, etc.). However, neither micro-organisms or fungi to carry out experiments not proven himself as a leader. Some researchers believe that the development of the acute infectious diseases can influence the course of skin diseases the weakening of the immune system protection (reversible and irreversible). However, despite numerous studies, the infectious theory has not been confirmed.
VIRUS. The viral nature of the disease has a large number of devotees. However, based on studies of virus theory has not been confirmed in the main, because never observed transmission of the disease loss sick healthy people, despite the fact that there were hundreds of direct blood transfusion to the patient, to the patient.
Trigger mechanisms of the disease
In many studies, causes of psoriasis, doctors have found that there are other precipitating conditions for the occurrence of the disease. Causes of psoriatic arthritis symptoms may be both internal and external factors.
The most common causes that trigger the disease:
- the disease can cause acute and chronic infectious processes in the body (SARS, sinusitis, tonsillitis, scarlet fever, sore throat, etc.), as well as condition after vaccination. As a rule, these diseases weaken the immune system, leading to recurrent disease;
- 40% of patients in the development of exacerbations and cause psychological stress situations (different types of depressions, crises of your personal). Therefore, to reduce acute symptoms, so often prescribed tranquilizers;
- trigger psoriasis can long-term treatment of drugs, especially antibiotics, and immunomodulators. These drugs can cause disorders of the immune system in response to a stimulus;
- an important role in the development of or exacerbation of the disease play bad habits (Smoking, alcohol), and improper nutrition of the patient with the abuse of fats and fast carbs;
- symptoms of psoriasis may be due to exposure to chemicals for outdoor use (especially the hands), which are often used in everyday life, including the means of the parasites;
- exacerbation perhaps a violation of the integrity of the skin by mechanical effect (trauma, burns, injections, bites, etc.);
- relapse of psoriasis can cause inflammation of the skin, including fungal infections from develop a rash on the hands, etc. in addition, the cause of psoriasis may be an acute allergic reaction.
- As a rule, the disease is exacerbated by precipitating factors (separately or together), so you should adhere to certain rules, in order to avoid a dangerous situation.
Primary symptoms psoriasis can occur at any age, but its development in children occurs more serious consequences and complications. In adulthood psoriasis threat of serious other diseases.
Causes of psoriasis in children
Based on the results of the student illness in the immediate family a few generations, to do biochemical investigations in patients who have family ties, including healthy, it is found that the development of psoriasis in children is an important ROLE HEREDITARY FACTOR predisposing to disease.
If one parent suffers from psoriasis, the probability that a child with psoriasis is 25%. If the sick, both parents, the risk of getting a child who has psoriasis is about 75%. Interesting is the fact that most often the psoriasis is through the maternal line. Psoriasis is hereditary (family) tracking researchers varies from 15 to 47% of cases of all diseases of the psoriasis in children. However, despite the thorough investigation of the genetic theory of disease, its causes, the child and the adult patient has not been fully elucidated.
Preschoolers and school-age children causes of psoriasis can be a strong emotional stress, fear, etc. A certain regularity, through which it would be possible to identify a single cause of psoriasis in children and adolescents does not exist.
Many scientists and doctors are inclined to multifactorial theory of disease development, which combines, in addition to heredity, a number of other factors.
Symptoms of the disease
Psoriasis is an atypical reaction to any stimulus. Psoriasis is characterized by appearance of itchy plaques of different sizes. Normal skin cells Mature in 3 weeks, but in psoriasis they dry after 5 days, leading to severe itching, especially of the head or hands. To relieve acute symptoms is addressed with proper care.
Some of the most common symptoms of psoriasis are:
- the appearance of pink-red psoriatic plaques with dry white pieces. As a rule, most often they are localized on the knees, elbows, hands and head (the hairy part);
- when nail psoriasis is marked dystrophy of the nail plate of the hands, the violation of form and color the nails. Severe form can develop degenerative changes;
- itching and dandruff of the head (near the hairline);
- cracking of the skin followed by pus psoriasis areas of the body;
- sometimes it is possible to hyperthermia and deterioration of the General condition of the patient.
It is important to note that the symptoms worsen at certain times of the year. There are 3 types of psoriasis depending on the time of year (winter, summer, and uncertain). Patients with the summer type of psoriasis is substantial, sudden exacerbation, which require longer-term treatment. The winter type is characterized by the fact that the symptoms of psoriasis are weak and give treatment is most effective. When a vague type of psoriatic arthritis symptoms can occur at any time of the year and is characterized by frequent relapses.
Therapeutic treatment of the disease
Despite the fact that the cause of psoriasis is not fully understood, today is the most effective methods that contribute to long-term remission:
- recommended the cold treatment (low temperature), which helps in the most advanced cases;
- internal symptoms are removed using plasmapheresis (filtering of blood);
- neutralization of symptoms is carried out actively with the help of PUVA therapy and special iodine-bromine, radon and sulphide bath.
In addition, the positive effect observed in the treatment with salts and dead sea mud to fight the symptoms of psoriasis even in the head.
Prevention of psoriasis
To prevent the disease is necessary to observe preventive measures, including:
- Prevention of trauma to the skin on the hands, head, face, etc.
- You should not stay a long time in direct sunlight.
- You need to get rid of bad habits.
- Require weight management, especially when the acute symptoms.
- You should avoid stressful situations.
- Psoriasis on the head is recommended to use special medicated shampoos and lotions.
- In all cases, should be monitored regularly by a dermatologist.
Psoriasis is a multifactorial disease and its causes are different, so a positive result can be achieved if the start of treatment with strict adherence to all recommendations of a dermatologist. This approach can not provide long-term remission and prevention of possible complications.
