Technology inhalation therapy for respiratory AZ. Polls via "Step 2". 5th "Medicine", "Pediatrics", "Medical and preventive care" 4 Rate Faculty Number of hours 201 3 years 1. Background: With dignity to statistics the average annual increase in the incidence of allergic diseases in Ukraine among children and adults is 0.3%. Based on current understanding of the pathogenesis of allergic diseases (AZ) cure them by means of pharmacotherapy is still impossible. Existing drugs - steroids, antihistamines, etc. antyleykotryyenovi, although allowed to significantly increase the effectiveness of AS helped to monitor their progress, but their influence, unfortunately, does not allow for drastically affect the immunological aspects of these diseases and to cause long-term remission. According to an official document of the WHO (1997) and the majority of domestic and foreign experts, the only method that really affects every pathogenesis of AS, lets cut the development and course of AS is specific immunotherapy (SIT) allergens (synonyms - "specific alerhovaktsynatsiya" " specific hyposensitization, "etc.). Some important abstract from an official of the World Health Organization - WHO POSIT ION PAPER "A llergen immunotherapy therapeutic vaccines for allergic disease ", Genev a, J an uary 27-29, 1997, confirming the above information: • The use of allergen immunotherapy has shown its true effectiveness ity in patients with allergic rhinitis, conjunctivitis, allergic asthma, allergic reactions to insect stings. • The nasal, sublingual or oral immunotherapy, in which the injected be high doses of allergens may also be effective. • Immunotherapy is the only method that can influence the natural history of allergic diseases, it can also prevent the transition of allergic rhinitis in asthma. According to this document, the effectiveness of specific immunotherapy is: When insect allergy 85-95% In hay fever 80-90% With year-round rhinitis 70-80% In bronchial asthma 70-75% Specific immunotherapy in the future retain the properties of a single method that can alter immune-mediated hypersensitivity to certain allergens patient. 2.

Organization of the content of teaching material After pref Tanna and the students, the teacher conducts roll call and voiced topics in class. 1. By out-patient teacher introduces students to the basic principles of treatment of allergic diseases: 1. Educated patients. 2. Elimination therapy. 3. Alerhovaktsynatsiyu (specific immunotherapy). 4. Pharmacotherapy. 2. Teacher then demonstrates the importance of each stage of treatment. 2.1 The teacher draws attention to the fact that education of patients and working with them is unbreakable. Traces wires you by: 1) collective classes (known "school with asthma"); 2) popular programs in the media; 3) publications. Summary of key measures in allergic diseases should include: a) elimination activities; b) behaviors during specific immunotherapy; c) the nature of pharmacotherapy; d) the ability to control of respiratory function (ERF). 2.2 The teacher emphasizes that every doctor should know exactly Directions elimination therapy. He should know the main allergens that are typical of its region, a calendar of deadlines or pylkuvannya sporulation of fungi. In addition, it should take into account ty and availability of ecologically dangerous enterprises in region nutrition population, its mentality, especially of Ocho Health Care of and more that make it as a professional. Elimination therapy (if it is not a short-term measure) really can take only the sick. Therefore, education of patients, working with them ("komplayns") is a very important event and to some extent affect the prognosis of allergic diseases. Then the instructor explains what you need to carry out activities in various allergic pathologies, such as: Elimination measures for hay fever: For an allergist is very important knowledge of regional plants with the terms pylkuvannya nayvyrazhenishymy sensitizing properties (indicative calendar pylkuvannya plants in Ukraine, see 6). In the hay fever season in pylkuvannya as appropriate: • limit exposure to air; • wet gauze curtain vents; • Do not open the windows in the car; • conduct daily wet cleaning of rooms; • remember that the air conditioning system does not rule on Java pollen in rooms, but this can be accomplished in a special "Beza lerhennyh-wards"; • eliminate the consumption of food, medicines, which may include pollen or other parts of plants. The teacher said that the m IL pollen and certain types of vegetables and fruits can may be cross-reactions. Yes, wormwood can be shared determinan you with cumin, anise, sweet pepper, pollen of trees such as alder, hazel, birch, can provide cross-allergic reactions to allergens apples and nuts. In individuals with hypersensitivity to grasses may be allergic to bread. Off season pylkuvannya patients do not have to take in food: - Honey, which, understandably, includes different pollen; - Carefully take apples, citrus fruits, strawberries; - Not desirable to use raw vegetables (carrots, beans). As an allergy to pollen is sometimes combined with an allergy to certain species of fungi, the spores of which can also rapidly dissipate in the air, it is appropriate at any time of year: • do not work in the fall and spring in the garden in the country, because of rotten grass, leaves are a source of mold I ref mushrooms; • use caution in food dough, champagne, beer, brew; • treat fungal diseases of the skin, nails, hair; • the presence of air conditioning in the car should go to her after she warms up and will work at least 5 minutes (release spores into the air conditioner machine). To prevent breeding of mushrooms in the room is a special hooked-shuvachi air. You should not start plants. Surfaces on which there are traces of fungal growth, it is advisable to handle fungicides. Air conditioners can reduce the amount of pollen in the air, but it applies to modern air conditioners that need to be cleaned periodically according to the instructions. There are special devices to reduce the concentration of the various particles in the air (filtration of mechanical, electrostatic precipitate chewing), special filters for heating systems. There is also a little different manitni filters are useful for both patients with hay fever, and the presence of house dust allergy dokomponentiv. If you are allergic to household allergens is recommended: - Use a special coating on the bed (made in Ukraine); - Wash clothes in hot water (not below 70 ° C); - Maintain humidity in the apartment above 50%; - Replace carpeting to linoleum, wood flooring, parquet; - Do not sleep on upholstered furniture; - Remove all "cleaners", ie objects and things that adsorption tion to dust ourselves; - Vacuum cleaners cleaning 1 time per week with HEPA filters that for is supported allergens; - Apply acaricide - special solutions for the destruction mikroklischiv (Asahozap, Asahsiyzi), benzyl benzoate, 3% solution of tannin; - Periodically make way for frost, UV irradiated. The living room should: 1. Do not smoke. 2. Exclude furniture, wool blankets, quilts (replaced by cotton or synthetic). 3. Do not keep domestic animals and fish. 4. Do not use air fresheners, insecticides, mothballs. 5. Have the kitchen hood. 6. Regularly (without the patient) to hold wet cleaning. 7. Relative humidity should be 35-50%, the temperature is not higher than 22 ° C. 8. It is desirable to have air conditioners. Some acaricides (benzyl benzoate, taninova acid, etc.) at regular polar applying to some extent destroy the population of mites. More effective is the use of special coatings and dense tissue. The bedroom should be: 1. Remove furniture, carpets, drapes. The floor must be de made from wood or covered with linoleum, furniture - wood or metal, for windows - blinds or curtains cotton. Everything should wash or bathe. 2. The cabinet does not store blankets, felt hats, wool products and anything that collects dust. Cabinet doors should be closed tightly. 3. Doors and windows should be well fitted, during the pollution of the air, the wind, they should be tightly closed. 4. Wet cleaning 1-2 times a week. Patients on go to bed 3-4 hours after cleaning. 5. Have foam pillows, cushions and wash bedding should be 1 per week at or below 55 ° C. 6. Mattress to put a plastic bag with zipper "lightning." 7. A child should not play with soft toys. If you are allergic to cats or dogs coat should do everything possible to get rid of animals in the apartment. But a few months thereafter On the air in the room can be found the remains of animal allergens. The greatest danger is the epidermis cats, which are volatile and delay is formed only filters with pore diameter of 3 mm. Persons who keep dogs should be aware that a different breed of animal allergens have different strengths, but safe in this regard is not. If you are allergic to cockroaches should always kill these insects. But the need but remember dezinsektytsydiv danger for patients with allergies. If you are allergic to epidermal allergens should remember also the possibility of cross-allergic reactions to meat animals and serum preparations obtained from these species (eg, horse-chu, bull, antidiphtheritic serum used with treated tion and diagnostic purposes, the presence of certain types of horse meat sausages). Also, keep in mind the general measures that will be useful for patients with any allergy, for cause psevdoalerhichni, cross-reactions, nonspecific hiperreaktyvnisttoscho. Thus, the presence of the parents (especially both) of allergic disease fluctuations should expect the possibility of allergies in children. Therefore, the ne riod pregnant women should avoid smoking, alcohol, drugs, likars cal means infections that increase the likelihood of allergies and approximating the term of its clinical manifestations. In early childhood are also important: 1. Features nutrition in childhood, particularly early switch to bottle-feeding; 2. The presence of flat domestic animals, fish and birds. Keep in mind that the most dangerous in terms of food allergies at any age (especially in children) are coffee, cocoa, chocolate, citrus fruits, strawberries, strawberries, eggs, honey, fish, eggs, crabs, crayfish, milk , carrots, beets, tomatoes, nuts. Common factors that may contribute to allergic diseases, including allergic rhinitis are: time of year when the child was born, vaccinations, living conditions, smoking (passive and active), the presence of domestic animals, fish, chemicals in the home and at work; manipulation mouth, frequent introduction into the nose, inhalation drugs, surgery. At the reception the students themselves, under the supervision of the teacher to give patients advice elimination measures and bring patients to their great need. Only working with patients is the key to effective specific immunoglobulin noterapiyi for the understanding of the nature of this treatment, regular ness administration of allergen, duration of treatment, the possibility of certain complications is very important. Since the conduct of specific immunotherapy is built on the dosed administration of 'reasons them "allergens should do everything possible to reduce nekontrolo-tion proceeds allergens relevant to the patient. The patient must periodically (and in the event of significant changes in the state of healthy care, the presence of large local reactions - immediately!) inform your doctor about all the nuances of the disease, condition after administration of allergens like. The bottom line pharmacotherapy of allergic diseases need roz'yas mates of patients to ensure that they not only understand the basic mechanism of action of drugs which they are appointed, but their side effects.We should not hide the fact that each farmakopreparat useful enough to much higher ratio of "utility / side effects." However, we believe that patients need to understand the essence of pharmacoeconomics, that they should explain that the most effective drugs RAO is usually the most cost-effective. Specifically, it is about antihistamines, patients should be aware of the duration of action, optimal timing of application, opportunity, major side effects during the performance of their admission, the major side effects (effects on the central nervous system, the conducting system of the heart). It should allay their safety relevance to eufillina, Teofedrin and, contrary, overly cautious on (3agonists, inhaled hlyukokor-tykosteroyidiv (IGCC). ENT should change the safety of many patients on prolonged use of decongestants, danger of self independently destination for children. It should explain the high capacity mucosa ing membrane of the nose quickly absorb drugs. By administering ing topical preparations should be treated almost the same responsibilities as the introduction of a vein! Teacher explains n ryznachayuchy kromony, inhaled corticosteroids, their effect will come no earlier than 2-3 weeks and that these drugs are much safer than systemic corticosteroids. The patient should be taught to use pre inhaled Paraty, or benefit from their use is negligible. They are blame must rinse the mouth after use of inhaled corticosteroids. You nyknennya unusual sensations, sudden ineffectiveness of drugs on guilty to get a patient to see a doctor. Also, it is necessary to co ntrol respiratory function (ERF). The ability of patients to use pikfluometry to control the functions this external respiration is a very important event. This should develop ' yasnyuvaty patients, work in groups, teaching her's to this method, SAG tosuvannyu (ß 2-agonists on the testimony FDD). 2.3. Specific immunotherapy The teacher stresses that the district and even better drugs that affect the number of pathogenic mechanisms of allergic reaction - an allergic inflammation, release of neurotransmitters - steroids, for all its positive qualities, can not affect remedy the immunological stage of allergic reactions and will not prevent the formation nude cell immune memory following famous cascade effects. Tob a cancellation of these drugs will lead necessarily to restore symptom volumes of allergic diseases. There dynym method that can fundamentally change the status of patients with allergic diseases remains specific immunotherapy. Teacher benefits imposes expenses you specific immunotherapy allergic to pharmacotherapy diseases, such as: - Maintaining long-term remission after successful completion of the course of specific immunotherapy; - Preventing the progression of the spectrum of allergens to which formuyet be hypersensitivity; - Utyazhchennya disease prevention and transition milder clinical manifestations of severe allergies; - Reducing the need for allergy medications. In the last decade, the efforts of scientists were able to establish a number of immunological mechanisms of specific immunotherapy in force at all levels of an allergic reaction to contrast farmakopreparativ. Then the teacher introduces students to the composition of vaccines, indications for use and inputs alerhovaktsyn. Conduct SIT displayed when: • confirmed and g E-mediated nature of the disease; • disease has a long course of severe manifestations; • no full elimination of allergens; • there is any need standardized allergen; • there is a clear confirmation of the role of allergens (pollen, household allergens, house dust mites, hymenoptera venom). Students are introduced to the inputs alerhovaktsyn in clinical diagnostic laboratories: This parenteral methods (subcutaneous, intradermal and Application of skin-squares method) and noninvasive: oral, sublingual, intranasal, con 'S ktyvalnyy, inhaled and some other methods nerozpovsyudzheni SIT. Depending on the length of courses and rozriznyayuttsilorichnu preseason SIT. The teacher must be noted that each patient is individually regimen. Moreover, SIT can combine with the base and symptomatic treatment of allergic disease. teacher then demonstrates the benefits of oral SIT method, its safety, efficiency, ease of use and affordability. The effectiveness of SIT is very variable and depends on many factors. Also a teacher of students with nayomyty with contraindications for SIT (absolute and relative), and the restrictions to apply. An important point is sensitized to students who can expect unwanted and reaction tion and the introduction alerhovaktsyn complications and their prevention. 2.4. In this section, the teacher introduces students to the main areas of drug therapy of allergic diseases. They can be divided into three groups: drugs acting on allergic inflammation - among the highest efficiency of these facilities are corticosteroids (both local and systemic effects), but the first inhalation. The use of topical corticosteroids is a safe method of inhalation therapy. antymediatorni agents (antihistamines, antyleykotryyenovi); symptomatic medications (decongestants, bronchodilators, vidharkuyuchi). The teacher said that the development of drugs farmakoindustriyi acquire properties and broad lines (combination therapy). At present, more standards are implemented treatment of major diseases that allow all patients, regardless of place of residence and qualifications of physicians to obtain current therapy. 6.
