Hay fever (hay fever) - the most common diseases people of any age.Hay fever - caused by pollen allergic disease, mainly affecting the eyes and mucous membranes of the respiratory tract.Pollen almost all plants have pronounced allergenic activity, so contact her at highly sensitive people is the development of seasonal diseases
Hay fever - Causes
Flowers, as it turned out, it is not always fun.Nectar Ambrosia only ancient Greeks called the food of the gods, while all modern doctors believe this plant is the most dangerous enemy of human health.The first is similar to hay fever description of the disease found in the extant writings of the ancient physician Galen.A century after his van Helmont observed seasonality of asthma and is linked with a possible exposure to pollen.It was only in the early 19th century (in 1819), an official statement of the English doctor John Bostoka marked the beginning of the history of the disease called hay fever.A British doctor Blakely also suffe
light on the mechanism of this disease has been shed recently.The cause of hay fever is not as said before "genetic predisposition" to allergy to pollen, but directly inherited disease.This was confirmed recently found genes that convey susceptibility to various allergens inherited.Usually they are inherited through the maternal line, but sometimes can be transmitted and paternal.Also, there are works that prove the relationship between the specific form of hay fever and "defective genes".
From all the above should be - just hay fever is regarded as hereditary pathology, then preventive measures must be appropriate.The most important is to limit contact with the baby grass pollen allergen from the very first stages of life.It was found that the baby, who was born in the period of flowering trees and / or grasses, more likely to develop hay fever, and in its more severe form.The greatest danger lies in wait for the baby during the first six months after birth, and in the last three months of fetal life.Hence the conclusion - if at least one of the potential parent suffers from pollen allergy (especially his mother), it is imperative to plan conception.This measure will significantly reduce the risk of developing hay fever in a child
seasonal hay fever
greatest danger of seasonal hay fever are wind-pollinated plants, which provide a huge mass of small pollen, penetrating into the pores of the mucosa even through clothing.For example, in Russia, the main enemies of patients with hay fever are angiosperms trees such as poplar, oak, birch, hazel, alder (first bloom).Period of flowering: mid-April - mid-May.
gymnosperms such as cedar, pine, fir and spruce pollen are much larger, and develops an allergy to it very often.Despite this, the Japanese cedar in Japan is one of the main causes of hay fever.
After wither trees, begins flowering grasses (reygrass, fescue, orchard, timothy, etc.), Which according to the chronology of flowering are the enemies №2.Risk of cereals lies in the fact that some people eat: oats, wheat, rye.In this case, the pollen allergy is added food, and can not help any cooking.
From late June begins flowering Asteraceae, and the most hard-core Allergy grass from their list is ragweed, which produces a huge amount of pollen.Many areas in Russia and the CIS as a result of the huge spread of ragweed can be called disaster areas.Every year, thousands of people in developing caused by ragweed pollen asthma.
I would like to focus attention on the fact that Asteraceae are often included in the formulation of various drug charges, and our people are very fond of treatment herbal remedies.For the prevention of children's diseases such as the king's evil (exudative diathesis), parents often bathe the baby in the succession or chamomile broth, while both of these plants contain a huge amount of pollen.In the case of a child in a chromosomal gene of the above, it is deteriorating condition.We describe the documented cases very severe reactions to chamomile enemas wash eyes infusion of chamomile, wormwood tea.Absolutely any natural honey also may be increased danger, as it has a huge amount of pollen.
often during flowering Compositae may experience a cross-reaction with some food, and a categorical prohibition falls eating nuts and mustard.Certain threats are peaches, apples and cherries.Not so simple, and alcohol use.Champagne allergies is not recommended to drink, but the vermouth is strictly forbidden, as all its varieties contain wormwood, a reaction which can be up to anaphylactic shock and angioedema.
Some scientists believe that the danger is only the pollen itself, and if, for example, an apple a good wash, the person risks nothing.This statement is erroneous, since the properties of the pollen is determined glycoproteins, and they found themselves in the fruit.However, in this case, it would be a food hay fever, but this patient does not become easier
Hay fever - symptoms
Hay fever manifested the characteristic triad of symptoms: tearing (causes conjunctivitis), runny nose, and bronchospasm.The most typical symptoms of hay fever - severe itching in the nose throat and nasal cavities, painful bouts of sneezing, nasal discharge with copious liquid secretions that alternate bouts of complete nasal congestion.Then, in the allergic process gradually involved auditory (eustachian) tube, and nasal mucosa that is manifested by increased sensitivity to visual and olfactory stimuli, hoarseness and pain in the ears.
In some cases, the only symptom of hay fever is - pollen asthma (bronhospastichesky syndrome), which occurs in about 30% of patients with other symptoms of hay fever.In 5% of patients with pollen asthma diagnosed as an isolated syndrome.In this case, the clinical picture of pollen asthma is very similar to the symptoms of asthma.Sometimes there may be swelling of the face (angioedema) and urticaria.
In the period of acute body temperature usually remains within normal limits, although sometimes it can be observed an increase up to 39 ℃, the patient has insomnia, weakness, sweating, headache.
Hay fever in children often occurs unusual.At preschool age children is often a so-called disguised as hay fever, which manifests itself embodied in the ears, which sometimes comes to a complete loss of hearing, and other clinical signs of the disease are completely absent.Hay fever other children may show only a slight reddening of the conjunctiva and frequent scratching of the nose ("allergic salute").Some kids like the disease is severe asthma without rhinitis
hay fever Hay fever develops in the normal way: pollen enters the respiratory tract and is deposited on the mucous membranes of the respiratory tract and lungs.In addition, the pollen falls and then remains on the eyeball and mucous membranes of the eyes.Immediately after the penetration into the body of pollen starts the process of immune defense to recognize the allergen.Once this happens, it turns on the mechanism of the production of antibodies capable of inhibiting the foreign agent.This process is referred to allergists process of sensitization.The propensity of the organism in the presence of a child's predisposition to allergic reactions can get its start at any age child.To start the hay fever rather minimal amount of pollen.
sensitization process apparently does not manifest.Often, from the time of first contact with the allergen to the onset of clinical symptoms of allergic disease may take several months.
For example, in the case of the child's contact with ragweed pollen in the case of baby predisposition to develop allergic reactions, his body immediately begin the process of recognizing foreign agent taken root in our case - ragweed pollen.After that, the immune defense develops antibodies that continue to remain in the body to contact with ragweed pollen in the next year.And now it is hay fever for the next year will be presented in all its "glory."This process in the development of allergic hay fever is the final phase of the process is called "resolution."That is why most parents often wonder why hay fever developed for no apparent reason, and that those allergens to which the child has been previously completely immune.In fact, during all this time in the body the baby proceeded process of sensitization, turning then allergy
Diagnosis of hay fever
In the case of the slightest suspicion of seasonal hay fever, to avoid possible diseases such downstream character (pneumonia, acute bronchitis,ARI) should consult a physician or allergist.Only a competent allergist-immunologist can make the correct diagnosis - hay fever and assign adequate current state of treatment.If this child is sick, the initial phase of the survey will be a detailed survey of parents on how to develop the baby and what illnesses he suffered.After that, both children and adults, taken for laboratory testing analysis of the contents of the nasal mucosa and blood.
next diagnostic step is to determine what kind (for the individual) is the pollen allergen.The best time to conduct allergy tests is winter time of the year - the lack of time as the most irritating factor (pollen) and entering the body of specific drugs.With this picture of the disease is the most reliable
most often to determine the allergen provoking hay fever, allergists use prick test or scratch test.These tests are carried out not earlier than two weeks after the reception was over antiallergic drugs and always in winter.
Allergic tests carried out as follows.On one of the forearms is some minor scratches, over which is applied thereafter drops preparations with high concentrations of various allergens.These allergens can also be administered by injection under the skin.After twenty minutes, based on the dimensions of each of the scratches physician visually determines the appropriate allergen (more application site allergen red spot, the more active human allergen of an allergic reaction).
allergological tests, however, do children who have reached the age of five.For children who are younger, doctors recommended an alternative method of research - specific blood test protein antibodies produced by the immune system in response to certain types of pollen.This method of investigation can be conducted throughout the calendar year, without regard to the patients received pharmacological drugs and health.This is the only way to identify hay fever in young children.Hay fever is usually diagnosed during pregnancy the same way
Hay fever - Treatment
Unfortunately modern science to change the genotype of today are not able, however, to minimize the suffering it can.The treatment of hay fever, are based on numerous advertising "miracle" drugs must often does not bring results, as helping one person, other drugs only harm.
How to treat hay fever, can only recommend a qualified allergist.The most common allergic reaction to suppress the patient is assigned to a course of antihistamines.To reduce the runny nose associated with ongoing discomfort shown burying his nose special vasoconstrictor drugs.
How to cure hay fever forever?Unfortunately, today it is impossible, however, to maximize ease symptoms quite capable.Main is a modern treatment of hay fever - specific giposenbilizatsiya.This method is administered subcutaneously miniscule doses selected allergen (2-3 injections per week, the course of 40 injections).This procedure is carried out only in the absence of (autumn or winter) pollen in nature.As a result - the organism appears to the input resistance mean allergen.
Hay fever - seasonal allergies, so from it in the literal sense, and you can escape by climbing onto the flowering plant quarantine, for example in the mountains, or the area where "your" allergenic plant simply does not grow.The inhabitants of the highlands hay fever is extremely rare.If the trip is not possible, you should try to follow these guidelines:
• unless absolutely necessary (especially in the hottest time of the day), try not to leave the premises.Also remember that the maximum concentration of pollen in the air is observed in the windy
• During flowering cause allergic reactions of plants should be completely excluded outings
• Walking should be only in the evening, better in cloudy weather or after rain
• In the window openings, be sure to pull the gauze or the grid and continually moisturize them.Regularly and in a timely manner to carry out wet cleaning.To reduce the risk of allergic reactions to household chemicals or dust should be used during cleaning gauze
• The room residence of the patient is necessary to remove the soft toys and carpets, asthey always collect on yourself a huge number of dust
Prevention of hay fever is including in particular diet, which can significantly alleviate the condition.As such, the diet is quite simple, but its observance will help prevent severe allergic symptoms.The patient should be removed from their diet the following foods: eggs, chicken meat (especially the legs), cherries, pears, honey and bee products, foods with food dyes.Also, be sure to eliminate drugs, of which consists of herbal ingredients as they can be a catalyst for even more severe allergic reaction
allergy to antibiotics
Antihistamines, relieving the symptoms of hay fever, deserve special attention, as there is a persistent belief,it is absolutely harmless.In this regard, the abuse of such drugs simply enormous.People think you have an allergy, without proper control accounts and take such drugs as the suprastin, pipolfen, tavegil, diphenhydramine and so on. Unfortunately, not all that simple, and often occurs in conjunction with hay fever are allergic to antibiotics.To cancel a life-threatening drug it is necessary to identify as soon as possible.
addition categorically counter antihistamines reception with bronchitis, asthma, shortness of breath and wheezing attacks.These medications dried mucous pharynx, concentrated and so thick mucus and as a result - clog the bronchial lumen in the deep lung contribute to the development of infection.In such cases, the reception is shown phlegm drugs opposite action
