The COVID-19 pandemic is the most challenging global health crisis of our times. Vaccination against COVID-19 plays a key role to control the current pandemic situation. The risk of allergic reactions to new COVID-19 vaccines is low. However, there is a debate on the safety in allergic patients following post marketing findings by different agencies. Our aim is to understand from current experiences whether children with cow’s milk or food allergy are at higher risk than a general population for allergic reactions to COVID-19 vaccines. Current data indicate that patients with a history of allergy to cow’s milk or other foods, even if severe, should receive COVID-19 vaccine in a setting with availability of treatments for anaphylactic reactions and under medical supervision. Recipients should be discharged after a protracted observation period of 30 min if no reaction developed.

Identification of offending allergens in patients with food allergy is a very important part of an allergist’s activity. Objective. To study the structure оf sensitization to food allergens among children in Moscow and Moscow region and to determine the significance of sensitization to milk proteins . Methods. The level and class of specific IgE in blood serum of children with IgEmediated allergic diseases were examined with RIDA AllergyScreen method. Serum of children with high level of specific IgE to milk allergenic proteins was studied. The level and ratio of specific IgE to individual milk allergens were revealed. Results. The structure of sensitization to food allergens was determined. It was revealed that cow’s milk allergens are the leading triggers of food allergy, especially in early childhood in Moscow and the Moscow region. The features of sensitization to cow’s milk proteins among children were analyzed. Conclusions. According to the study, about half of children with IgEmediated food allergies in Moscow and the Moscow region have sensitization to cow’s milk proteins. The leading role in the frequency of sensitization belongs to whey proteins of milk. Among them sensitization to а-lactalbumin was detected more often. The questions about the selection of hypoallergenic milk formulas for feeding of children with allergy to cow’s milk proteins were discussed.

В течение последних лет частота встречаемости пищевой аллергии у детей постоянно увеличивается. Одной из наиболее частых причин пищевой аллергии у детей грудного возраста является аллергия на коровье молоко. Распространенность пищевой аллергии коррелирует с растущим объемом исследований и публикаций, изучающих связь факторов окружающей среды с формированием оральной толерантности в раннем возрасте. Управление этим процессом происходит в критический период развития, который получил название «окно возможностей», и ключевая роль принадлежит микробиоте и ее метаболитам. В течение этого периода влияние окружающей среды может иметь долгосрочное воздействие на состав микробиоты, иммунную регуляцию и восприимчивость к болезням. События во время этого критического окна влияют на долгосрочное здоровье человека. Ранняя колонизация сообществом микробов в рамках определенного критического временного окна имеет решающее значение для правильного развития иммунной системы. Грудное молоко остается золотым стандартом вскармливания, но роль его в профилактике пищевой аллергии на сегодняшний день не доказана. Более детальное изучение иммунологических факторов грудного молока и механизмов диалога между микробиотой и иммунной системой, в частности, действия определенных компонентов (пробиотики, пребиотики и метаболиты), помогает разработке новых стратегий профилактики иммуноопосредованных заболеваний, в т. ч. пищевой аллергии. Пребиотики, пробиотики и метаболиты представляют на сегодняшний день огромный интерес для управления аллергией через ускорение формирования иммунологической толерантности не только для первичной, но и для вторичной профилактики при лечении аллергии к белкам коровьего молока. In recent years, the incidence of food allergies in children has been steadily increasing. One of the most common causes of food allergy in infants is cow's milk allergy. The prevalence of food allergy correlates with a growing body of research and publications investigating the relationship of environmental factors and immune development inthe newborn. The «window of opportunity» is critical period of early immune development, and the key role belongs to the microbiota and its metabolites. During this period, environmental influences can have long-term effects on microbiota composition, immune regulation, and susceptibility to disease. Events during this critical window affect long-term human health. Early colonization by the microbial community within a certain critical time window is critical for the proper development of the immune system. Breast milk remains the gold standard for feeding, but its role in preventing food allergies has yet to be proven. A more detailed study of the immunological factors of breast milk and the mechanisms of microbiome-immune crosstalk, in particular, the action of certain components (probiotics, prebiotics and metabolites), helps to develop new preventive strategies. Prebiotics, probiotics and metabolites are of great interest today for managing allergies by accelerating the formation of immunological tolerance not only for primary, but also for secondary prevention in the treatment of allergy to cow's milk proteins.

Food allergy is a potentially life-threatening condition in which there are no approved pathogenetic treatments other than elimination of the causal allergen and relief of acute allergic conditions. IgE- mediated form of food allergy remains a serious and growing problem worldwide. Its prevalence is steadily increasing, and is a severe psychosocial and economic burden for patients and their families. Cow's milk and products based on it are important components of a child's diet, which are introduced into the diet of children of the first year of life, but can cause allergic reactions. The traditional management of children with cow's milk allergy consists in prescribing an elimination dairy-free diet and a significant part of patients form tolerance to milk proteins by the age of 5 years. However, with persistent forms of allergy to cows milk proteins, the question is raised about the need for "active" tactics of patient management in order to form tolerance. Oral immunotherapy is a promising approach to the treatment of food allergies based on a gradual increase in the allergen taken, by analogy with standardized immunotherapy for respiratory allergens, until a maintenance dose is reached. Each stage of oral immunotherapy should be considered as a personalized therapy. This review contains an analysis of available studies on the effectiveness of oral immunotherapy in the treatment of allergy to cow's milk proteins.

Background: Urticaria can be the only sign of a food allergy or can be seen together with other signs and symptoms of a food allergy. Objective: To determine the demographic, etiologic, and clinical features of food-induced acute urticaria in childhood. Methods: Patients suspected of food-induced acute urticaria were included in this prospective cross-sectional multicenter study. Results: Two hundred twenty-nine urticaria cases were included in this study. Seventeen patients who did not meet the inclusion criteria of the study were excluded. Of the 212 included cases, 179 (84.4%) were diagnosed with definitive food-induced acute urticaria. The most common foods causing acute urticaria were cow’s milk, hen’s eggs, and nuts in 56.4, 35.2, and 19% of cases, respectively. The positive predictive value of a history of milk-induced acute urticaria together with a milk-specific IgE >5 kU/L for cow’s milk-induced acute urticaria was 92% (95% CI: 81–96%). A history of cow’s milk-induced and/or hen’s egg-induced acute urticaria was consistent with a definitive diagnosis of food-induced urticaria (Chen’s kappa: 0.664 and 0.627 for milk and eggs, respectively). Urticaria activity scores were higher in patients with food-induced acute urticaria (p = 0.002). Conclusion: Cow’s milk, hen’s eggs, and nuts were the most common allergens in the etiology of childhood food-induced acute urticaria. Although the urticaria activity score provides guidance for diagnosis, an oral food challenge is often essential for the definitive diagnosis of a patient with a history of food-induced acute urticaria.

<b><i>Background:</i></b> Cow’s milk allergy (CMA) is the most common IgE-mediated food allergy and Bos d 5 is the major allergen in cow’s milk proteins. More than 60% of the patients with CMA are sensitized to this protein. <b><i>Methods and Results:</i></b> A recombinant protein, encoded by a synthetic gene and consisting of reassembled Bos d 5 fragments, was expressed in <i>E. coli</i> strain BL21 (DE3) cells and purified to homogeneity. The B5M lacked relevant IgE-reactivity and allergenic activity compared with Bos d 5 in dot-blot and basophil activation assays. T-cell proliferation experiments demonstrated that B5M preserved the main T cell epitopes of Bos d 5. Immunization of rabbits with B5M induced protective IgG antibodies that blocked the binding of patients’ IgE antibodies to the wild-type allergen and inhibited the degranulation of basophils induced by Bos d 5. <b><i>Conclusion:</i></b> Thus, we developed a new strategy, which was based on rational molecular reassembly for allergen-specific immunotherapy (AIT) of CMA and food allergy.

Allergenic Activity

The purpose of the work was to establish in a model experiment the allergenic activity and danger of the extracts obtained from the dust of dry products of cow's milk processing (DPMP), containing complexes of soluble whey (WMP) or casein milk proteins (CMP), as a stage of hygienic regulation of the content of dust DPMP in the air of the working area. Experiments on albino guinea pigs sensitized by the intradermal injection of standard doses of WMP and СМР solutions into the ear revealed the development of severe allergic reactions in the animals of the experimental groups with the prevalence of mixed mechanisms of immediate anaphylactic and delayed cell-mediated types. According to the criteria for the classification of industrial allergens, the WMP and СМР complexes have a strong allergenic activity and are differentiated to the 1-st class of allergenic hazard, which determines the classification of the DPMP dust containing them as extremely dangerous industrial allergens. This is confirmed by the established high levels of indicators of allergic-diagnostic reactions in vivo and in vitro when testing sensitized WMP and СМР animals with a solution of skim milk powder dust, indicating the presence of antigenic determinants of whey and casein milk proteins in it and a real ability to form cross-allergic reactions in the body of workers to dust from all dry milk processing products containing these proteins.

Abstract Purpose Propofol is an intravenous sedative used in many patient populations and care settings. Although generally considered safe and effective, the drug has historically been avoided in patients with reported allergies to egg, soy, and/or peanut on the basis of the manufacturer’s prescribing information. Concerns exist for potential adverse events, increased medication costs, reduced efficacy, and risk of medication errors when using alternative agents. Here we present a critical examination of the literature concerning cross-reactivity of food allergies with propofol to provide evidence-based recommendations for the evaluation and management of potential allergic reactions. Summary Literature regarding the history of propofol allergy warnings and clinical trial data were assessed to provide an alternative perspective on avoidance of propofol in patients with food allergies. Suspected trigger molecules are discussed with evaluation of the antigenic potential of excipient ingredients used in the manufacture of multiple propofol formulations. Evidence-based recommendations are provided for pharmacist-led screening of adult patients with reported food allergies to support selection of propofol or alternative therapy. Conclusion There is a lack of definitive evidence that propofol must be routinely avoided in patients with reported allergies to egg, soy, and/or peanut products. Data from clinical trials suggest that propofol is safe for patients with nonanaphylactic food allergies. Patients who do experience allergic reactions following administration of propofol should undergo further testing to definitively identify the specific trigger and prevent future unnecessary avoidance of preferred medication regimens. Pharmacists can play an important role in interviewing patients with reported food allergies to better determine the risk vs benefit of propofol avoidance.
