Approbation of the method of identification of priority and competitive areas of applied medical science using allergology as an example
Rebrova O.Y.
Abstract
The previously proposed approach to the identification of priority and competitive subjects of medical research is applied to the field of science «allergology». The arguments that this area of science is the applied one are given. Search for publications on socioeconomic burden of allergic diseases in Russian Federation has been carried out, the only study on bronchial asthma has been found. Evidence gaps for medical technologies used in the allergology are identified (for atopic dermatitis as example), which represent the directions for priority research.

Rapid in vitro assessment of hypersensitivity with whole blood leukocyte histamine release assay
Babakhin A.A., Smirnov V.V., Gushchin I.S., Ilyina N.I., Khaitov M.R.
Abstract
Background. Clinical application of leukocyte histamine release assay (HRA) can be enhanced through the development of automated reversed-phase high-performance liquid chromatography with mass spectrometry (RP-HPLC-MS/MS) employing of whole blood (WB) samples. The purpose of this study was to evaluate the possibility to use WB-HRA technology for the in vitro diagnosis of hypersensitivity employing RP-HPLC-MS/MS. Methods. Method principle: heparinized whole blood samples after substitution of plasma with PIPES buffer («reconstituted» blood) are incubated at 37 °C with different concentrations of substances (allergens, drugs, chemicals, food etc.) suspected in relation to hypersensitivity reactions. Release of histamine is occured mainly from basophilic granulocytes depending on their sensitivity to stimulating substances (allergens etc.). The released histamine is subsequently direct determined in the supernatant using RP-HPLC-MS/MS technology. Heparinized whole blood (8 ml) was drawn from patients with sensitivity to D. pteronyssinus (D1), birch pollen (T3) and peach (F95) confirmed by case history and results of skin prick tests or detection of specific IgE. After removing plasma and substitute it with PIPES buffer aliquots of «reconstituted» blood were put into separate tubes (300-450 μl for macro-method) or to wells of U-shape 96-well micro-titer plate (150-200 μl for micro-method) already contained different concentrations (dilutions) of histamine standard, anti-IgE and allergenic extracts D1, T3, F95 including their chemically modified forms sD1 and sF95. After 1 h incubation at 37 °C tubes or plates were centrifuged and supernatants from each tube (macro-method) or well of the plate (micro-method) were directly analyzed for histamine content by RP-HPLC-MS/MS. Results. It is shown that the levels of histamine released from leukocytes of whole blood of patient sensitized to D. pteronyssinus upon stimulation with non-modified D1 extract are much higher than that of upon stimulation with modified sD1 that means that chemical modification of allergen leads to suppress of B-cell epitopes. It seems that this method is suitable for evaluation of hypersensitivity to allergen, as well as for detection of allergenicity of modified allergens (allergoids). We also found a significant reduction (in 60%) of histamine release from blood leukocytes upon stimulation with T3 extract in patient with sensitivity to birch pollen after allergen-specific immunotherapy (ASIT) in compare to the level of histamine before ASIT. These data indicate that our method of histamine release assay can be convenient as in vitro test for monitoring and evaluation of ASIT efficacy. It was also studied histamine release from blood basophils of patient with sensitivity to peach, confirmed by case history and detection in serum specific IgE. Incubation of patient's whole blood with peach extract (F95) resulted a histamine release at the level comparable to that of stimulated with anti-IgE. This high level of histamine is correlated with the level of allergen-specific serum IgE. Besides the incubation patient's blood with modified peach extract sF95 induced histamine release two times less than that of non-modified F95 indicating substantial reduction of sF95 allergenicity. So this methodology for detection of histamine released from leukocytes of whole blood may be successfully applied for diagnosis of food allergy employing of laboratory made allergenic extracts. Conclusion. Speed and simplicity of performance including the requirement of small quantities of blood makes the WB-HRA employing RP-HPLC-MS/MS a useful laboratory tool not only of scientific interest (detection of allergenicity of modified allergens, peptides etc.) but also of practical significance for evaluation the degree of sensitivity of patients to allergens (including those who received anti-allergic medication or ASIT), analysis of pathophysiological responses to drugs, chemicals and other compounds suspected for their adverse side effects.

Achievments of control of seasonal allergic rhinitis symptoms: the results of open, randomized comparative study of second generation antihistamines
Bodnya O.S., Nenasheva N.M., Andrenova G.V., Siniavkin D.O., Bodnya Y.V., Kubanova E.T.
Abstract
Seasonal allergic rhinitis (SAR) is one of the most common allergic diseases. The first choice for control of SAR symptoms is the second-generation antihistamines (AHP-II). The aim of this study was to evaluate the comparative efficacy of ebastine 20 mg/day, cetirizine 10 mg/day, and loratadine 10 mg/day in adult patients with mild symptoms of SAR due to pollen grass allergy. 30 patients aged 18 to 65 years who received treatment for 14 days took part in the study. The duration of the study for one patient varied from 25 to 28 days. As a result, the efficiency of all three AHP II in the control of mild symptoms of SAR was demonstrated. However, the analysis of the scales (TNSS and TNNSS) after the end of the 14-day treatment period revealed that compared to patients treated with loratadine and cetirizine (TNSS scale (p=0,0303), TNNSS (p=0,0091) the best results were observed in the group of patients taking ebastine. Moreover, patients who received the ebastine experienced a statistically insignificant but steady tendency to decrease the level of eosinophilic cationic protein (ECP) in nasal flushing (-37,9% of the baseline values), in contrast to loratadine and cetirizine. All drugs showed a high safety profile. To conclude, the investigated AHPs -II are effective and safe in control of mild symptoms of SAR in adult patients, though the rate of onset of the effect and its level for nasal and non nasal symptoms was significantly higher in patients receiving ebastine 20 mg compared to cetirizine 10 mg and loratadine 10 mg.

Samoylikov P.V., Mazurina S.A., Gushchin P.I., Gervazieva V.B.
Abstract
Objective. The aim of this study was to research a sIgE allergen profile of birch pollen and to evaluate a contribution of some homologous food allergens as well as latex allergen to the development of sensibility in allergic rhinitis (AR) / rhinoconjunctivitis patients, in focus of cross-reactivity and oral allergy syndrome.. Methods. Blood sera of 21 AR/rhinoconjunctivitis patients (at the age of 3 to 16) and 20 healthy persons without allergy symptoms were used. sIgE to birch pollen, soybean, latex, apple and celery as well as the total IgE levels were measured by the ImmunoCAP method (Phadia, Sweden) and the ELISA kits (Alkorbio, Russia). Results. We detected high total IgE levels, sIgE to allergens of birch pollen, apple, celery, as well as to recombinant allergens of birch Bet v 1, Bet v 2 and soybean - Gly m 4 in AR patients. Correlation analysis of IgE humoral response to homologous proteins showed the direct valid dependence between the sIgE levels to birch isoallergen Bet v 1 and soy isoallergen Gly m 4 (r=0,84; p<0,05). There was also the direct valid correlation between the sIgE levels to birch isoallergen Bet v 1 and allergens of apple and celery (r=0,67 and 0,57, accordingly). Conclusion. Correlation between the IgE humoral antibody response to the major allergen of birch pollen Bet v 1 on the one hand and allergens of soy, apple and celery on the other hand shows that cross-reactivity can play an important role in exacerbation of clinical symptoms in AR/rhinoconjunctivitis patients including oral allergy syndrome.

Allergic rhinitis: the choice of rational treatment
Sobolev A.V., Kozlova Y.I., Pyatakova A.V., Aak O.V., Klimko N.N.
Abstract
Allergic rhinitis (AR) is one of the most common diseases. Basic AR therapy includes both antihistamines of the second generation for per os administration in mild AR, and intranasal corticosteroids in the treatment of moderate AR. In clinical practice, oral antihistamines (in combination with intranasal corticosteroids) can be rationally replaced with intranasal antihistamines. Momate Rhino Advance nasal spray (a combination of azelastine hydrochloride and mometasone furoate) is promising medication when used as firstline therapy in the treatment of moderate and severe manifestations of AR

Experience of modern skin care series Atopic® using in atopic dermatitis children
Elisyutina O.G., Litovkina A.O., Fedenko E.S.
Abstract
Atopic dermatitis - chronic allergic skin inflammatory disease with genetic predisposition, dysbalance of immune response, dysfunction of an epidermal barrier and influence of various exogenous and endogenous factors. Epidermal barrier dysfunction leads to rising of permeability of a skin for allergens, microbs and nonspecific stimuli, as well as to sensitivity to various external influences. Clinically these implications are shown by skin xerosis symptoms therefore. According to modern clinical guidelines, the moisturizing agents, so called emollients, have to be used at all disease stages. Own data on use of modern skin care series Atopic® in complex therapy of atopic dermatitis patients are presented in the article.
