Background. The research is focused on the particularities of formation and course of atopic dermatitis in infancy depending on the range of sensitization and class of revealed antibodies. Methods. The article presents the results of clinical and immunological observation of 116 children aged from 1 month to 3 years with the clinical-anamnestic signs of atopic dermatitis. The immunological observation consisted of the following stages: determination of concentration of the general IgE, quantitative testing of concentrations of the serum IgE and IgG4 antibodies to allergens of cow and goat milk, chicken eggs and wheat, house dust and through the immune-enzyme analysis. Results and discussion. According to the results of the immunological observation the patients were divided into 3 groups: I - IgE+IgG4 - positive, II - IgG4 - positive, III - absence of above-mentioned classes of antibodies. The patients of group I are characterized by the early sensitization to cow milk proteins, the manifestation of the disease up to 3 months appears on pure breast feeding. The detection of the specific IgE antibodies to allergens of chicken eggs is a sign of danger of the development of sensitization towards inhalation house dust allergens and of the formation of respiratory allergy. For the children of group II the later age of manifestation of skin process (in more than half of children after introduction of milk food) and easier course of disease are significant. Anamnesis of the disease and the clinical manifestations of one third of patients of group III in the absence of the evidence of IgE-sensitization coincides with that of the patients of group I (age of manifestation, severity of disease). In accordance with received results, we can suggest that in this group there are patients with the unidentified immunopathological mechanism of formation of the disease. Conclusion. The immunological observation of infants by the detection of the specific IgE and IgG4 antibodies to widespread food allergens allows to reveal the peculiarities of immune response which in their turn define the clinical-anamnestic signs of atopic dermatitis.

Background. Malformations in epidermal barrier in children with atopic dermatitis (AD) can cause transcutaneous sensitization with further development of allergic diseases that can worsen the AD course and significantly reduces patients’ quality of life.Objective. The aim of the study was to determine the effect of topical treatment and maintenance therapy with pimecrolimus 1% cream (PIM) and topical glucocorticosteroids (tGCS) in infants with AD on reducing the risk of developing transcutaneous sensitization (due to the levels of specific IgE to the cow milk protein over time) and on reducing the disease severity (by the EASI scale).Methods. The study included children aged from 1 to 4 months with early manifestations of moderate and severe AD. The severity of AD was estimated via the EASI scale at start of observation, then at 6, 9 and 12 months of life. The class and level of specific IgE to cow milk proteins (CMP) were determined by the ImmunoCAP method at the point of enrolment and at the ages of 6 and 12 months. Statistical analysis of studied indicators dynamics and their comparison in research groups was carried out using multifactorial dispersion analysis.Results. The study included 36 patients. All patients have received standard tGCS therapy in combination with emollients (wet wrap) for 10 days. The maintenance therapy was prescribed in postacute period. It included topical calcineurin inhibitor PIM 2 times/day for 3 months, then double application (morning/evening) 3 times/week up to the age of 1 year old (group 1). Other group had maintenance therapy — tGCS2 times/week for 3 months, and then at AD aggravation (group 2). Group 1 has shown lower level of sensitization to CMP at the age of 6 and 12 months and more significant decrease in AD severity according to EASI scale compared to group 2.Conclusion. The treatment with PIM is effective in therapy of AD and prevention of transcutaneous sensitization in infants.

Background. Various sources of mammalian milk have been tried in CMA. Objectives. To determine whether camel milk is safer than goat milk in CMA. Methods. Prospective study conducted at Hamad Medical Corporation between April 2007 and April 2010, on children with CMA. Each child had medical examination, CBC, total IgE, cow milk-specific IgE and SPT. CMA children were tested against fresh camel and goat milks. Results. Of 38 children (median age 21.5 months), 21 (55.3%) presented with urticaria, 17 (39.5%) atopic dermatitis, 10 (26.3%) anaphylaxis. WBC was 10,039±4,735 cells/μL, eosinophil 1,143±2,213 cells/μL, IgE 694±921 IU/mL, cow's milk-specific-IgE 23.5±35.6 KU/L. Only 7 children (18.4%) tested positive to camel milk and 24 (63.2%) to goat milk. 6 (15.8%) were positive to camel, goat, and cow milks. Patients with negative SPT tolerated well camel and goat milks. Conclusions. In CMA, SPT indicates low cross-reactivity between camel milk and cow milk, and camel milk is a safer alternative than goat milk.

Bronchial asthma is a chronic disease characterized by reversible airway obstruction with clinical manifestations of recurrent wheezing episodes, airway inflammation, and their hyperreactivity. Timely diagnosis of bronchial asthma in early childhood will allow adequate prescribing therapy and controlled management of patients, which in the future will reduce the risk of serious complications and improve the quality of life of patients.The aim of the study – to identify the influencing factors on the manifestations of atopic reactivity in children with bronchial asthma, depending on the content of IgE specific to house dust antigens in the blood serum, in order to optimize the management of the disease.Material and methods. A comprehensive clinical and paraclinical examination of 79 school-age children with atopic bronchial asthma was carried out in the Regional Children's Clinical Hospital and the City Children's Polyclinic in Chernivtsi. According to the concentration of specific IgE to the house dust allergen, the patients were divided into two clinical groups. The first (I) clinical group included 55 children in whom the concentration of these antibodies in the blood exceeded 3.5 kU / l, the second group (II) consisted of 24 patients in which the level of specific IgE was below this value. According to the main clinical signs, the comparison groups were compared.Results. It was found that the proportion of patients in the first group who had contact with tobacco smoking of their parents was higher than in the comparison group. Constant contact with tobacco smoke, when both parents have this bad habit in the family, increases the likelihood of developing hypersensitivity to house dust in children with asthma by almost 9 times. At the same time, bronchial asthma was more often combined with atopic dermatitis in these patients, while low concentration of specific IgE to house dust was associated with comorbidity of asthma with allergic rhinitis. The risk of moderate to severe bronchial asthma in patients with low IgE levels increases significantly. The probability of developing the phenotypes of late-onset asthma and exercise-induced asthma in children with low concentrations of specific IgE to house dust increases by 3 and 2 times, respectively. The number of schoolchildren with an extremely high concentration of IgE (more than 100 kU/l) to D. Pteronyssinus antigens was twice as high as in the comparison group, and every second patient also had very high levels of antibodies to D. Farinae tick.Conclusion. Children with atopic hypersensitivity to house dust allergens have an increased chance of comorbid bronchial asthma and atopic dermatitis, late-onset asthma and physical exertion, asthma is much more severe, which must be taken into account when personalizing specific therapy.

AbstractGoat milk is a source of nutrition in difficult areas and has lesser allerginicity than cow milk. It is leading in the area for nutraceutical formulation and drug development using goat mammary gland as a bioreactor. Post translational modifications of a protein regulate protein function, biological activity, stabilization and interactions. The protein variants of goat milk from 10 breeds were studied for the post translational modifications by combining highly sensitive 2DE and Q-Exactive LC-MS/MS. Here we observed high levels of post translational modifications in 201 peptides of 120 goat milk proteins. The phosphosites observed for CSN2, CSN1S1, CSN1S2, CSN3 were 11P, 13P, 17P and 6P, respectively in 105 casein phosphopeptides. Whey proteins BLG and LALBA showed 19 and 4 phosphosites respectively. Post translational modification was observed in 45 low abundant non-casein milk proteins mainly associated with signal transduction, immune system, developmental biology and metabolism pathways. Pasp is reported for the first time in 47 sites. The rare conserved peptide sequence of (SSSEE) was observed in αS1 and αS2 casein. The functional roles of identified phosphopeptides included anti-microbial, DPP-IV inhibitory, anti-inflammatory and ACE inhibitory. This is first report from tropics, investigating post translational modifications in casein and non-casein goat milk proteins and studies their interactions.

Most food allergy cases are associated with a limited group of allergens. This could be attributed to an increased ability of some foods to sensitize and trigger allergic reactions. However, there are no validated animal models to evaluate the sensitizing or allergenic potentials of proteins. Our aim was to evaluate three protocols of adjuvant-free intraperitoneal sensitization that differ in the time points for sample collection (days 14, 28 and 35 from beginning of the sensitization) and also in the number of immunizations (2, 5 and 3, respectively). Ovalbumin (OVA; 0.05 mg), cow milk proteins (CMP; 0.025, 0.05 and 0.25 mg), and potato acid phosphatase (PAP; low allergenic protein; 250.0 mg) were administered intraperitoneally (ip) to BALB/c mice (n = 4–6) and the protein-specific IgE and IgG antibody responses were evaluated using ELISA. Additional serum protein-specific IgE antibodies evaluations were carried out after IgG depletion. Anti-OVA IgE antibodies were detected in mice from all three protocols. The responses were higher in the group of mice that underwent the 28-day protocol than in those that underwent the 14- or 35-day protocols (p < 0.01 and p < 0.05, respectively). Anti-CMP IgE antibodies were detected in both the 14- and 28-day protocols, but the response was higher in the group that underwent the 28-day protocol (p < 0.001). The anti-CMP IgE antibody response detection was improved after serum IgG depletion (p < 0.001). Anti-PAP IgE antibodies were not detected. Mice with undetectable serum levels of protein-specific IgE triggered anti-OVA, -CMP, and -PAP IgG responses. An adjuvant-free 28-day protocol with five ip immunizations seems appropriate for evaluation of the inherent sensitizing or allergenic capacity of the studied proteins. Reproducible results were obtained utilizing the BALB/c mouse strain. Inter-laboratory studies including a larger number of proteins should be carried out to validate this model.

AbstractIgE sensitisation in tropical areas is under-reported. A 2 year retrospective cohort study of allergy data specific to aero and food allergens in Brunei demonstrated that specific IgE levels to house dust mite (Dermatophagoides pteronyssinus, D.farinae, Blomia tropicalis) were highest in this population and correlated with atopic dermatitis (p < 0.001). Shrimp and peanut were the most common food allergens. A dominance of house/storage mite sensitization is seen in Brunei which is consistent with other tropical countries.

A series of 302 patients reporting immediate hypersensitivity symptoms to inhalant allergens was evaluated by both puncture skin testing and the radioallergosorbent test (RAST) using 13 common inhalant allergens. Agreement between the two tests varied from 71% to 93% for the various allergens and averaged 82%. The best correlation, 93%, was obtained with mixed grass pollen allergens. If a purified allergen, rye group I, was used the correlation rose to 97.5%. The correlation was 88% for the mold Alternaria, and the negative-sera did not become positive when tested over a wide range of dilutions. Fifty-eight percent of the patients with house dust allergy reacted to house dust mite (Dermatophagoides farinae). Correlations of 71% to 93% were obtained with ten weed and tree pollens. The only patients in whom positive RASTs were found with negative skin tests to the same antigen had either severe atopic dermatitis or decreased skin response to exogenous histamine. Sera from a group of 20 patients with positive allergy history but negative skin tests also had negative RAST. The radioallergosorbent test appears to add little information to that obtained by a comprehensive allergy history and puncture skin tests in the great majority of children with inhalant allergy. The only exceptions were children with severe atopic dermatitis, suppressed skin reactivity or dermatographism.

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.

This work presents the electrophoretic profile of goat and cow milk samples and their mixtures using microfluidic and conventional electrophoresis. The microfluidic method allowed the separation of the major caseins from milk, excepting the goat κ-casein.  Besides, the major whey proteins were separated with perfect distinction of A and B β-lactoglobulin variants. Comparing to SDS-PAGE, a variation in the molecular weight was observed in all milk proteins. However, A and B β-lactoglobulin variants could not be isolated using SDS-PAGE. Although urea-PAGE did not show high resolution among whey proteins, γ-, κ-, β-, and α-caseins were clearly identified. This method also showed a lower limit detection of cow milk in mixture samples than the "lab-on-a-chip" electrophoresis. In both methods, the highest linearity obtained from plotting total percentage against cow milk concentration was observed by using cow αs1-casein (R2 = 0.986 and R² = 0.973). This result indicates that microfluidic electrophoresis is an effective tool to detect the presence of some proteins in goat and cow milk, and in mixtures. Microfluidic chip technology might will complement the current methods for analyzing milk proteins, highlighting its speed amount of reagents and whey protein separation, which showed a better result than urea or SDS-PAGE
