Sharikadze O.V.Background. This study determined the efficacy of sublingual allergen–specific immunotherapy (SLIT) in Ukrainian children younger than 5 years of age with allergic rhinitis and bronchial asthma sensitized to house dust mite allergens. Methods. A cohort prospective study was conducted over a two years period with assessment of the sensitization towards inhalant allergens, measured in-vivo by wheal size and number of positive reactions on the standard skin prick test (SPT). SPSS was used to analyse any statistical correlation. Results. A total of 125 atopic asthma or/and allergic rhinitis with the mean age of 4.11 ±0.83 who were sensitized to house dust mites Dermatophagoides pteronyssinus and/or Dermatophagoides farina were included. 47 children received two-years SLIT to treat house dust mite allergies using standardized extract of sublingual allergens containing a mixture of house dust mites (Der.  pteronyssinus and Der. farinae) in the correlation of 1(0,175 НЕР):1(0,175 НЕР) (Diater, Spain). These patients were mono-sensitized with Der. pteronyssinus and Der. farinae or were SPT poly-sensitized, but these patients only had house dust mite allergy symptoms. In this group the assessment of clinical efficacy of SLIT showed the significant differences in VAS before treatment and 6 months after its receiving. The symptom “nasal obstruction” was assessed as 2.3±-1.6 points  at the beginning of the therapy, and the data reduced almost twice (1.3±-1.1); Р <0,05 after 6  months of SLIT;  then (12 and 24 months) it decreased to 0.91±0.9 and 0.34±0.5; Р <0,01, correspondingly. Conclusion. This study has shown that using of SLIT in atopic asthma or/and allergic rhinitis children under 5 year sensitized to house dust mites is an effective and safe treatment method and allows to quickly (over the first 6 months of SLIT) control the symptoms. The data of comparative analysis in the group of patients who didn’t receive SLIT has pointed to high frequency of disease symptom occurrence after the end of baseline therapy.KeyWords: sublingual allergen-specific immunotherapy, children, bronchial asthma, allergic rhinitis, sensitization, allergens, Diater  ОСОБЛИВОСТІ ЛІКУВАННЯ ДІТЕЙ ДОШКІЛЬНОГО ВІКУ, СЕНСІБІЛІЗОВАНИХ ДО АЛЕРГЕНІВ ДОМАШНЬОГО ПИЛУШарикадзе О.В.Це дослідження визначило ефективність сублингвально алерген-специфічної імунотерапії (SLIT) українських дітей молодше 5 років з алергічним ринітом та бронхіальною астмою, сенсибілізованих до алергенів пилових кліщів. Методи. Проспективне дослідження когорти проводилося протягом двох років з оцінкою сенсибілізації до інгаляційних алергенів, виміряної in-vivo за розміром пухирів і кількості позитивних реакцій на стандартному тесті на шкірі (SPT). Для аналізу статистики використовувався пакет SPSS. Результати. Обстежено 125 дітей (середній вік 4,11 ± 0,83 років) з атопічною астмою та/або алергічним ринітом, які були сенсибілізовані до домашніх пилових кліщів Dermatophagoides pteronyssinus та/або Dermatophagoides farina. 47 дітей отримали дворічний курс SLIT з використанням стандартизованого екстракту сублінгвальних алергенів, що містять суміш кліщів домашнього пилу (Der. Pteronyssinus і Der. Farinae) в співвідношенні 1 (0,175 НЕР): 1 (0,175 НЕР) (Діатер, Іспанія). Пацієнти були моносенсібіровани Dermatophagoides pteronyssinus і / або Dermatophagoides farina або були полісенсібілізовані (за SPT), однак симптоми розвивалися тільки на домашній пил. У цій групі оцінка клінічної ефективності SLIT показала значні відмінності до лікування і через 6 місяців після його отримання. Симптом «носової обструкції» оцінювався як 2,3 ± 1,6 бала на початку терапії і зменшувалися майже в два рази (1,3 ± 1,1); Р <0,05 після 6 місяців SLIT. Потім (12 і 24 місяці) він знизився до 0,91 ± 0,9 і 0,34 ± 0,5; Р <0,01, відповідно. Висновок. Дослідження показало, що використання SLIT при атопічній астмі та/або алергічному риніті у дітей до 5 років, сенсибілізованих до домашніх пилових кліщів, є ефективним і безпечним методом лікування і дозволяє швидко (протягом перших 6 місяців SLIT) контролювати симптоми. Дані порівняльного аналізу в групі пацієнтів, які не отримували SLIT, вказують на високу частоту виникнення симптомів хвороби після закінчення базової терапії.Ключові слова: сублінгвальна алерген-специфічна імунотерапія, діти, бронхіальна астма, алергічний риніт, сенсибілізація, алергени, Діатер. ОСОБЕННОСТИ ЛЕЧЕНИЯ ДЕТЕЙ ДОШКОЛЬНОГО ВОЗРАСТА, СЕНСИБИЛИЗИРОВАННЫХ АЛЛЕРГЕНАМИ ДОМАШНЕЙ ПЫЛИШарикадзе Е.В.Это исследование определило эффективность сублингвальной аллерген-специфической иммунотерапии (SLIT) украинских детей моложе 5 лет с аллергическим ринитом и бронхиальной астмой, сенсибилизированных к аллергенам пылевых клещей.

House dust mites are important cause for allergic rhinitis, and almost half of allergic rhinitis patients is sensitized to them. In patients with house dust mite allergy evidence of sensitivity can not be strictly achieved with medical history and patients complaints, since the cause-effect relationships are not obvious. At the same time incomplete allergological examination can lead to an incorrect definition of the main relevant allergens, and expensive treatment may not give the desired result in this cases. The estimation of the allergens for allergenspecific immunotherapy should be based on the disease history, detection of offending allergens by means of allergological examination in vivo with skin tests, nasal or conjunctival provocational tests, and component diagnostics if necessary. This approach based on use of provocational tests as a part of allergological examination is considered to be one of the ways to personalized therapy.

Abstract OBJECTIVE: To investigate the risk factors associated with allergic rhinitis in adults. METHODS: Using the 1:1 matching principle, 1096 cases of allergic rhinitis patients aged 18-65 years were selected as the observation group, and another group of healthy medical checkups were selected as the control group, and the data related to allergic rhinitis were collected by allergen testing and questionnaire survey, and univariate and multifactorial analyses were performed respectively. RESULTS: The univariate analysis showed that allergic rhinitis may be related to temperature changes, dryness and humidity, air pressure, wind speed, seasonal changes and exposure to allergens such as dust mites and house dust mites. After allergen testing of all patients in the observation group, it was found that dust mite and house dust mite were the highest percentage of allergens, accounting for 40.51%, indicating that environmental factors play a decisive role in allergic rhinitis. Multi-factor analysis showed that exposure to dust mites, house dust mites, Penicillium punctatum, Streptomyces crossatus and Aspergillus fumigatus were independent risk factors for allergic rhinitis when it was humid, when it was cold, when it was windy and when the air pressure was low. CONCLUSION: The epidemiological status of allergic rhinitis in adults in China was initially understood, and the main allergens were house dust mite and dust mite, which provided scientific epidemiological information for the standardized prevention and treatment of allergic rhinitis in this region.

Abstract. House dust mites are the most found allergens in homes scattered throughout the world that associated with allergic manifestations in the respiratory tract and skin, such as bronchial asthma, allergic rhinitis and atopic dermatitis. The most common house dust mite is from the family Pyroglyphidae, four of which have a close relationship with the incidence of allergy: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Dermatophagoides microceras, and Euroglyphus maynei. This study aims to determine the type and density of house dust mites in several habitats in the homes of people with allergic diseases. This study is a descriptive study using cross-sectional method. Samples were dust in allergic patient’s home in Malalayang I, taken from three habitats, namely bed (mattress and bed linen), bedrooms floor and sofa, as many as 96 samples. Of the 96 samples, there are 60 samples positive of dust mites and 36 negative samples. This study found 157 mites (124 adults and 33 larvae mites). Of the 124 adult mites were identified, there are 122 from order Astigmata with the dominant species is Dermatophagoides pteronyssinus, and two others of the order Prostigmata. In each habitat that is in the bed (mattress and bed linen), bedrooms floor and sofa, Pyroglyphidae is the most prevalent.Keywords: house dust mite, allergiesAbstrak.

House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room temperature () and 70% humidity () containing house dust mite food and active charcoal fibers. At 10 minute intervals, live and dead house dust mites were counted. All house dust mites instantly attached to the activated charcoal fibers and started to shrink almost immediately. There were no live house dust mites present as early as 40 minutes in some dishes while after 190 minutes all house dust mites were dead. In conclusion, activated charcoal fibers, if incorporated into bedding items, have the potential to control house dust mites in the indoor environment.

The aim of this study was to determine the effectiveness of the acaricide tri-n-butyl tin maleate, industrially applied to samples of carpets, mattress foam, and fabrics used for furniture upholstery, soft toys and shoe uppers. Approximately 100 adult house dust mites of the species Dermatophagoides pteronyssinus were inoculated into a Petri dish containing the sample (a piece of carpet, mattress foam, or fabric), treated with the acaricide, randomly collected. Mite-maintenance culture medium was added on top of each sample. After one, two, three, seven and 30 days of incubation at 25 ºC and 75% relative humidity, each dish was examined using a 40X stereoscopic microscope (40X). One hundred percent acaricide effectiveness was obtained in treated materials by the end of the 30th-day postinoculation period, under optimal conditions for mite maintenance.

The aim of this study was to determine the efficacy of sublingual allergen–specific immunotherapy (SLIT) in Ukrainian children younger than 5 years old with allergic rhinitis and bronchial asthma sensitized to house dust mite allergens. Material and methods: Four hundred and fifty children aged 28 months up to 5 years with rhinitis or asthma were examined. One hundred and twenty five children sensitized to house dust mites Dermatophagoides pteronyssinus and/or Dermatophagoides farina were included. In vivo and in vitro tests were made with a standard inhalant allergens panel. Results: The high information value of molecular diagnostics methods applied prior to prescription of the given therapy in children is analyzed. It has been found that in children under 5 sensitized to allergens of house dust mites Dermatophagoides pteronyssinus and/or Dermatophagoides farinae the application of sublingual allergen–specific immunotherapy therapy allows gaining control over the symptoms of the disease during the first 6 months. Conclusion: The high safety of SLIT in children has been proven. Comparative analysis in the group of patients not receiving SLIT shows a high frequency of symptoms of the disease after “free-of-symptoms interval” against full or partial baseline therapy denial.

AbstractBackground:Allergic rhinitis is strongly associated with the presence of house dust mites. This study investigated the long-term effects of allergen-specific immunotherapy. Allergen-specific immunotherapy was applied over three years. The study was based on a 10-year follow up of patients with allergic rhinitis.Methods:The study was conducted between 2001 and 2015. Skin prick test results and symptom scores were evaluated before (26 patients) and after 3 years (20 patients) of allergen-specific immunotherapy (using data from a previously published study), and 10 years after allergen-specific immunotherapy had ended (20 of 26 patients).Results:The symptom scores before allergen-specific immunotherapy were significantly higher than those obtained after 3 years of allergen-specific immunotherapy and 10 years after allergen-specific immunotherapy (p < 0.0175). There were no significant differences between the scores obtained at 3 years and 10 years after allergen-specific immunotherapy (p > 0.0175).Conclusion:Subcutaneous immunotherapy is an effective treatment for house dust mite induced allergic rhinitis.
