Introduction: An atopic status assessment (skin prick test or specific immunoglobulin (sIgE)) in asthmatic children is considered a milestone in identifying potential risk factors and triggers provoking loss of asthma control and asthma exacerbation. Objective: The study aims to perform a comparative analysis of different laboratory methods for a serological assessment of an atopic status in asthma and respiratory allergies in children. Material and methods: A total of 86 children were included, all of whom were diagnosed with bronchial asthma, aged from 5 to 17 years and screened for total IgE level using enzyme-linked immunosorbent assay (ELISA). In 48 randomly selected children, we performed a semi-quantitative serological in vitro assessment of the specific IgE antibodies against food and aeroallergen, using two different laboratory methods—Euroimmun Immunoblot and ImmunoCAP (Phadiatop/fx5). Results: In 70% of the children with a history of allergies, and 65.3% without clinically manifested allergies, multiscreen test ImmunoCAP Phadiatop/fx5 showed positivity and confirmed atopy. Our results showed a significant moderate to strong correlation between multiscreen ImmunoCAP Phadiatop/fx5, and Euroimmun specific IgE titers against aero-allergens—cats, mites, tree mix and food allergens—soy, wheat (р = 0.006), rice, р = 0.090), apple р = 0.007) and peanut. A sensitivity of 63% and specificity of 73.5% was observed for EUROIMMUN Pediatric (food allergens, IgE titer > 1) compared with the gold standard ImmunoCap/fx5. The mean value of total IgE is significantly higher in children with asthma and concomitant with allergic rhinitis compared to those without allergic rhinitis (mean 202.52 U/mL, IQR 102.50 (24.20–363.95) vs. 316.68, IQR 261.00 (109.20–552.50), p = 0.005). Conclusion: Establishing the spectrum of the most common respiratory and food allergens is an essential factor for maintaining asthma control, both through a strategy to avoid allergen exposure and by developing a recommendation plan. The immunoblotting technique is easily applicable in daily clinical and laboratory practice. It is also a cost-effective and reliable alternative to the “gold standard” ImmunoCAP Phadiatop/fx5 in diagnosing atopy in children.

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

Quality Of Life Questionnaire

Background.Allergic rhinitis (AR) significantly impairs the quality of life of the patients; however, a questionnaire alone is an insufficient and subjective measure of this condition. Obtaining an objective clinical assessment of the level of impairment will be valuable for its treatment.β-Endorphin is one of the most important mediators of both mental state and specific immunity. Thus, we investigated the possibility of usingβ-endorphin as a biomarker for evaluating the impairment level in AR.Methods.This study included 48 patients with AR and 32 healthy volunteers. The serumβ-endorphin level was determined by enzyme immunoassay, and the serum-specific IgE and total IgE levels were determined by immunoblot assay. The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) was used to assess the impairment level in the symptom duration.Results.Theβ-endorphin concentration was significantly decreased in AR patients compared to the healthy controls (p=0.000,p<0.05). There was significant negative correlation between the impairment level and serumβ-endorphin level (correlation coefficient:-0.468;p=0.001;p<0.05), but there was no association between the serumβ-endorphin and total IgE levels (p=0.947,p>0.05).Conclusion.β-Endorphin is a systemic biomarker that has the potential to assess the impairment level in AR and may therefore be a novel therapeutic target for the treatment of AR.

This study was conducted to determine the sensitivity to Dermatophagoides pteronyssinus (Trouessart) and D. farinae Hughes with skin prick tests (SPT) and serologic tests in patients with allergic rhinitis (AR), and to specifically search for those mites in homes of patients. A total of 51 participants, (23 patients and 28 controls) were utilized. Skin-prick tests with D. pteronyssinus and D. farinae allergens were performed on all participants, and serum levels of allergen-specific lgE and total IgE were also measured. Dust samples were collected from homes of all participants and examined under a stereo microscope. 977 D. pteronyssinus (mean 44.4/g) and 24 D. farinae (mean 4.0/g) were isolated from the homes of patients, whereas 35 D. pteronyssinus (mean 4.4/g), and four D. farinae (mean 2.0/g) were isolated from the homes of the controls. Patients with D. pteronyssinus in their homes had 95.5% sensitivity to the species according to SPT and 27.3 according to IgE. Patients with D. farinae in their homes had 83.3% sensitivity to the species according to SPT, and 50% according to IgE. Dermatophagoides pteronyssinus sensitivity in the controls was detected as 12.5% according to SPT; however, D. farinae sensitivity was not detected according to both SPT and mite-specific IgE. Differences between patients and controls utilizing SPT results was statistically significant, but not when using mite-specific IgE results. As a result, it was determined that patients with AR in Erzincan province were sensitized to D. pteronyssinus and D. farinae, and that their homes contained those species. It may be helpful to consider these findings in clinical assessment of patients with AR, and also in treatment utilizing immunotherapy techniques.

Aim: to determine the mechanism of food sensitization in children with chronic Opisthorchis felineus invasion. Patients and methods: during the epidemiological study the groups of patients (7–10 years) with chronic opisthorchiasis (n =237) and children without chronic opisthorchiasis (n =496) were formed. The investigation included interviewing of parents / guardians, measurement of total IgE, specific IgE to food allergens and component-resolved diagnostic, real-time PCR in stool samples. Results: the chronic opisthorchiasis invasion in children is associated with reduced risk of food sensitization, compared with non-infected group (9,7 vs 16,94%, OR =0,53; 95% CI 0,31–0,88; p =0,01). Opisthorchiasis of high intensity negatively correlated with increased level of specific IgE to food allergens in serum (OR =0,46; 95% CI 0,24–0,91; p =0,023). The association between level of total IgE and intensity of opisthorchiasis combinated with food sensitization was found. The sensitization to allergens class I (cyp c1, cor a11, gal d2, pru p3) is more prevalent in patients with opisthorchiasis, in uninfected children the sensitization to bet v1-homologues (mal d1, pru p1, cor a1, ara h8) is most common. Conclusions: the epidemiological data on the effect of the Opisthorchis felineus invasion on mechanisms of food sensitization in children were obtained.

Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA) method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant) were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%), IgE-bound wheezing/asthma (10.8%) and food allergies (7.4%), and to much lesser extent those of allergic rhinitis (3.4%) and urticaria (1.7%). The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005) (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%). Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

Abstract Background Worldwide, allergy affects more than one billion people, with particularly rising prevalence in industrialised areas. Specifically, young adults appear to be predominantly targeted for an allergy diagnosis. Allergic diseases in pregnancy are mainly pre-existing but could also occur de novo. The immunological changes while pregnant, with increased Th2 lymphocyte activity, can facilitate allergen sensitisation. Objective The aim of this study was to evaluate the pattern of specific IgE (sIgE) sensitisation to common inhalant and food allergens in pregnancy, and assess its relationship to self-reported allergic disease. Methods We assessed 200 pregnant women, aged 20–38 years (mean age = 29 years), participant of ELMA (Epigenetic Hallmark of Maternal Atopy and Diet) study, living in a metropolitan area, with no pregnancy associated metabolic complications, for total IgE and allergen specific IgE to 20 allergens. Results 48% of pregnant women were sensitised to at least one allergen, at a cut-off point of 0.35 kU/L and they were assigned as atopic. However 42% in atopic group were not reporting any allergic disease. The most common inhalant allergens were: pollen (24.5%) and animal dander (23.5%). The most common food allergens were: cow’s milk (5.5%) and apples (4.5%). 7.5% of women reported asthma, 21.5% allergic rhinitis, 11.5% atopic dermatitis and 18.5% food allergy. 8.5% of were taking medication for asthma or allergies. Atopic dermatitis had the highest tendency to become more severe during pregnancy. Total IgE values were significantly higher in atopic women. Conclusions Allergic sensitisation is a common phenomenon in pregnancy. Some sensitisations could be asymptomatic. Further studies should investigate if sensitisation in mothers confers risks for immune alterations in their children.

Background. To identify differences in sensitization to widespread allergens in patients with common allergic diseases: allergic rhinitis, bronchial asthma, angioedema, allergic urticaria and atopic dermatitis. Materials and methods. Determination of sIgE in serum using commercial and domestic reagent kits («AllergoI-FA-specific IgE» and biotinylated allergens of «Alcor Bio», St. Petersburg) was conducted in patients with allergic rhinitis, bronchial asthma, angioedema, allergic urticaria and atopic dermatitis. Results. There was a significant similarity between the spectrum of sensitization in patients with allergic rhinitis and asthma In atopic dermatitis patients the increasing of frequency of food and especially mold sensitization was estimated. The high degree of correlation between the moulds, plants and food allergens in atopic dermatitis was observed. Conclusion. The results obtained in the study can be interesting for physicians in allergological examination and for the researchers to identify new cross-reactive allergens.

Background.A good compliance in allergen-specific sublingual immunotherapy (SLIT) often comes from good short-term efficacy. We aimed to evaluate the pretreatment parameters which can predict the short-term clinical efficacy in children that underwent SLIT. Methods. 517 children with allergic rhinitis (AR) that underwent SLIT were recruited in this study. Baseline clinical characteristics and laboratory parameters were collected, and the clinical efficacy was evaluated using symptom and medication scores. A multivariate logistic regression model and receiver operating characteristic (ROC) curves were established. Results. A total of 303 (65%) in 466 children that underwent SLIT achieved short-term clinical efficacy. The time of using the air conditioner was negatively correlated with clinical efficacy, whereas the serum-specific IgE (s-IgE) levels, the serum IL-10 and IL-35 levels, and the s-IgE/total-IgE ratio were positively correlated with clinical efficacy. Conclusion. The time of using the air conditioner, serum-specific IgE (s-IgE) levels, serum IL-10 and IL-35 levels, and s-IgE/total-IgE ratio may be helpful for child selection before SLIT.
