Вот про АСИТ нашла кое-что на иностр.сайтах, может пригодится. Много статей про то что капли безопаснее- гораздо меньше побочки вызывают, можно капать даже младенцам (инъекции рекомендуют с 3-4 лет), капли можно не прекращать при простудах, отитах, бронхитах, в том числе и астматич.бронхитах в отичие от инъекций, при сенной лихорадке можно начать принимать капли за 6-8 недель, а не делать инъекции круглый год. Минус капель - стоимость. Везде рекомендованный курс АСИТ 3-4 года (инъекции). При аллергии на пылевого клеща АСИТ эффективно предотвращает развитие сенсибилизации на др.аллергены :1. Про возраст детей для вакцин - Allergen immunotherapy also cannot be used in patients who would have difficulty reporting signs and symptoms of a systemic reaction, such as children younger than three or four years. Эффективность при аллергии на пылевого клеща - In addition, early treatment with allergen immunotherapy in children who were sensitive only to house dust mites reduced development of sensitivity to other allergens.14 In contrast to the use of antiallergic medication, allergen immunotherapy has the potential to alter the natural course of allergic disease and prevent progression or development of multiple allergies. Consequently, many allergists have suggested its use earlier in the course of allergic disease.http://www.aafp.org/afp/2004/0815/p689.html2. Сравнение капель и инъекцийSublingual ImmunotherapyThe potential advantages of sublingual treatment are those of no injections, fewer regular doctor visits, no waiting periods after the injections, and a lower likelihood of side-effects. The main disadvantage of this form of treatment is cost. Much more allergen needs to be swallowed than injected, resulting in the cost per allergen being approximately 3 times that paid for injected treatments. Some people also dislike the salty taste. http://www.allergy.org.au/content/view/148/128/Although sublingual immunotherapy is not considered more effective that allergy injection therapy, there are several clinical situations when SLIT maybe a reasonable alternative.    Because SLIT is much less likely to cause adverse reactions, it can be self-administered at home.  The patient no longer has to drive to the doctor's office every week to get a shot and wait 20-30 minutes.    For patients who suffer from hay fever only in the Spring or late Summer, starting SLIT therapy 6-8 weeks before the pollen season may allow for rapid desensitization to tree, grass, ragweed or weed pollen, without having to take allergy shots for theentire year.  In Michigan, we recommend starting allergy drops for tree pollen sensitive patients around March 1st; for grass pollen allergic individuals around May 1st; and for ragweed pollen sensitive patients around August1st.    For patients already on allergy injection therapy, SLIT can be used as an add-on treatment, especially during high pollen seasons, when allergy shots alone are not providing satisfactory symptom relief.    SLIT therapy can be given to highly allergic infants and young children not old enough for allergy shots.    SLIT therapy has been used for patients with moderate or severe asthma who are not considered good candidates for allergy shots.    For patients with eczema that is flared by food allergy, SLIT therapy, along with avoidance of the food(s), can be quite helpful.  SLIT therapy may help control against flare-ups when accidental ingestion of offending food(s) occur.    Allergy patients frequently have several colds, sinus infections, ear infections (especially young children) and bronchitis throughout the year, and are therefore often sick and not well enough to receive allergy shots on a regular basis.  Because SLIT therapy rarely causes reactions, it can be administered to patients with chronic sinusitis, chronic otitis media and chronic asthmatic bronchitis.  Once patients have stabilized with SLIT, they can continue with allergy drops or switch over to allergy injections.    Patients with a real fear of needles can alternatively choose SLIT for allergic desensitization.    Patients who travel frequently for work or on vacation, SLIT allows the patient to continue allergic desensitization,without having to find a new doctor's office.http://www.michiganallergy.com/slit.shtml
