The rise of food allergy in childhood, particularly among developed countries, has a significant weight on public health and involves serious implications for patients’ quality of life. Even if the mechanisms of food tolerance and the complex interactions between the immune system and environmental factors are still mainly unknown, pediatricians have worldwide implemented preventive measures against allergic diseases. In the last few decades, the prevention of food allergy has tracked various strategies of complementary feeding with a modification of international guidelines from delayed introduction to early weaning. Current evidence shows that complementary foods, including allergenic ones, should be introduced into diet after four months, or even better, following World Health Organization advice, around six months irrespective of risk for allergy of the individual. The introduction of peanut is recommended before 12 months of age among infants affected by severe eczema and/or egg allergy to diminish the occurrence of peanut allergy in countries with high peanut consumption. The introduction of heated egg at 6–8 months of age may reduce egg allergy. Infants at high risk of allergy similarly to healthy children should introduce complementary foods taking into account family and cultural preferences.

According to statistical studies in recent decades, there has been an increase of allergic diseases in most countries of the world. Predisposing factors are the deterioration of the environmental situation, the total “chemicalization” of life and the forced use of drugs. Twenty years ago, the World Health Organization called the new century “the century of allergies” and the disease itself as an “epidemic”. As time has shown, these forecasts have come true: from 2001 to 2010, the number of allergic people in the world increased by 20 % and many of these patients suffer from ophthalmic manifestations of the pathology: the eyes are involved in the process in almost every second case. This is due to the fact that the eyes are directly exposed to the environment and a variety of external allergens. The most common disease of an eye-allergic nature is allergic conjunctivitis: approximately 15 % of the total population of economically developed countries suffer from it. Allergic blepharitis, eyelid dermatitis, keratitis, iritis, uveitis, retinitis and optic neuritis are much less common. The following manifestations are typical for allergic conjunctivitis: burning, lacrimation, pruritus, hyperemia of the eyelids and conjunctiva, photophobia. In the case of a transition to a chronic form, pronounced tissue changes are observed. Therefore, timely diagnosis and effective treatment certainly have a positive effect on the quality of life of the patient and the course of the disease. The treatment of patients with allergic conjunctivitis, first of all, consists in the maximum possible restriction of contact with the allergen. During desensitizing therapy, local and general drugs are used. Numerous studies have proven the advantage of targeted and effective antiallergic local therapy compared with systemic exposure. Currently used local ophthalmic antiallergic drugs belonging to various groups. The tactics of their use is determined by the acuity, severity and etiology of the process. When choosing a drug, in some cases, you should focus on the presence of substances that provide a double mechanism of action: a pronounced antihistamine activity in combination with the stabilization properties of mast cells, which has a quick and long therapeutic effect. This study evaluated efficacy of Vizallergol (olopatadin 0.2 %) application in cases of allergic conjunctivitis in 239 patients was evaluated. The medication arrested the symptoms of allergic conjunctivitis in 89 % of patients, at that the mean period of treatment made 10.7 ± 0.3 days. In the treatment of allergic conjunctivitis, the therapeutic efficacy of Vizallergol 0.2 % was comparable to opatanol 0.1 % and was found to be more comfortable for most patients due to the convenience of a single use.

Background. At present, due to high prevalence of allergic diseases which start in early childhood, the search for new prevention and treatment methods is in great demand. Aim. To study the effectiveness of the Russian-produced enterosorbent colloidal silicon dioxide in the treatment of patients with food allergies combined with atopic dermatitis and gastrointestinal manifestations. Materials and methods. An open, randomized, comparative clinical study of the enterosorbent (colloidal silicon dioxide) effectiveness has been conducted in parallel groups of infants and preschool children with food allergy skin and gastrointestinal manifestations. The main groups (1 67 children with food allergies and atopic dermatitis skin manifestations, 3 60 children with food allergies and gastrointestinal manifestations) received, along with basic medication, colloidal silicon dioxide enterosorbent day at an age-specific dosage twice a for 1014 days. Control groups (2 60 children with food allergies and atopic dermatitis skin manifestations, 4 60 children with food allergies and gastrointestinal manifestations) did not receive enterosorbent. All children underwent a clinical, functional and laboratory status assessment, including medical records analysis, a pediatrician clinical examination, narrow specialists (allergist-immunologist) examination, laboratory and instrumental research. The treatment effectiveness was being evaluated on the 14th day after the initiation of therapy and after 30 days. The therapy effectiveness was assessed based on regression of skin syndrome clinical and gastrointestinal manifestations, intoxication syndrome and laboratory parameters (IgE, hemogram eosinophilia duration). The study was conducted from 2017 to 2019. On the basis of LLC Modern Medical Technologies Clinics (Kemerovo). Results. Therapy with colloidal silicon dioxide increases the significance of food allergy skin manifestations positive dynamics, which makes it possible to reduce the volume of medication and the duration of topical glucocorticosteroids use to 5.340.35 days, in the compared group 10.520.85 days (p=0.002). All patients with food allergy combined with atopic dermatitis in the main and control groups noted positive clinical dynamics, appearing as decrease in the skin inflammatory reaction area and intensity. However, the of colloidal silicon dioxide use accelerates skin syndrome condition normalization significantly (group 1 skin syndrome persisted in 2.92.0% after 14 days, in group 2 18.34.9%; p=0.003). Colloidal silicon dioxide use accelerates humoral immunity state normalization (IgE) and peripheral blood parameters (hemogram eosinophilia). Colloidal silicon dioxide therapy accelerates food allergy gastrointestinal manifestations positive dynamics in children. Two weeks after the sorbent therapy started, gastrointestinal tract lesions symptoms frequency is less than in patients in the compared group. Diarrhea frequency before treatment started was 48.36.5%, 45.06.4% in the compared groups. After two weeks it decreased to 6.73.2% with the Polisorb therapy and to 16.64.8% in the compared group (p=0.003). Abdominal pain was noted by patients of both groups equally often before the study began. After 2 weeks, abdominal pain was noted by ten percent 10.03.9% of patients taking colloidal silicon dioxide and 25.05.6% of the compared group (p=0.009). Conclusion. Taking into account the composition of the colloidal silicon dioxide, it makes sense to include this medication in childrens food allergies complex treatment starting from infancy, which contributes to a more rapid relief of gastrointestinal system damage symptoms, life quality improvement for children and their parents, and decrease in medication load. When using colloidal silicon dioxide in children with food allergies, a faster dynamics of disease symptoms relief (p=0.003) was noted, which allows us to conclude that it is highly effective in the treatment of allergic diseases associated with food sensitization.

Regulating the composition of human breastmilk has the potential to prevent allergic diseases early in life. The composition of breastmilk is complex, comprising varying levels of oligosaccharides, immunoactive molecules, vitamins, metabolites, and microbes. Although several studies have examined the relationship between different components of breastmilk and infant food allergies, few have investigated the relationship between microorganisms in breastmilk and infant food allergy. In the present study, we selected 135 healthy pregnant women and their full-term newborns from a cohort of 202 mother–infant pairs. Among them, 69 infants were exclusively breastfed until 6 mo after birth. At follow-up, 11 of the 69 infants developed a food allergy in infancy while 22 showed no signs of allergy. Thirty-three breastmilk samples were collected within 1 mo after delivery, and 123 infant fecal samples were collected at five time points following their birth. These samples were analyzed using microbial 16S rRNA gene sequencing. The abundance and evenness of the milk microbiota and the number of differential bacteria were higher in the breastmilk samples from the non-allergy group than in those from the food allergy group. The non-allergy group showed relatively high abundance of Bifidobacterium, Akkermansia, Clostridium IV, Clostridium XIVa, Veillonella, and butyrate-producing bacteria such as Fusobacterium, Lachnospiraceae incertae sedis, Roseburia, and Ruminococcus. In contrast, the abundance of Proteobacteria, Acinetobacter, and Pseudomonas in breastmilk was higher in the food allergy group. A comparison of the changes in dominant differential breastmilk microbiota in the intestinal flora of the two groups of infants over time revealed that the changes in Bifidobacterium abundance were consistent with those in the breastmilk flora. Functional pathway prediction of breastmilk microflora showed that the enhancement of the metabolic pathways of tyrosine, tryptophan, and fatty acids was significantly different between the groups. We suggest that changes in the breastmilk microbiota can influence the development of food allergies. Breastmilk contains several microbes that have protective effects against food allergies, both by influencing the colonization of intestinal microbiota and by producing butyrate. This study may provide new ideas for improving infant health through early intervention with probiotics.

Abstract Allergy, formally called type I (or immediate) hypersensitivity  is one of four or more forms of hypersensitivity manifesting in various forms like, Atopic eczema, Allergic urticaria, Allergic rhinitis, Allergic asthma, , Food allergy,  etc.  The growing incidence of Food allergy needs attention since its burden is mainly on children and adolescents. Various factors has been attributed to the growing incidence of food allergy such as food habits, cooking habits, cultural differences, various developmental parameters and exchange of food products. The World Allergy Organization has estimated 220 to 550 million people suffering from food allergy with a large chunk of population from the developed countries. No concrete data is available on status of food allergy in India though some sporadic research has been published. In spite of diligent research worldwide, an effective mechanism to cure this condition has not been evolved till today. Since effectiveness of homeopathy has been proved in various allergy conditions, the modality of using the same has been explored in this article.   Key words: Food allergy, Homoeopathy, Type I hypersensitivity

Background: Food allergy (FA) is increasingly recognized with the highest prevalence in preschool children; there has been a significant increase in hospital admissions for systemic allergic diseases with anaphylaxis and food allergies. Hospital admissions for food allergy were noticed to rise from 6 to 41 per million between 1990 and 2000 worldwide . The prevalence of food allergy is increasing over time with significant geographic variations. It is estimated to affect 6% of children in the United States (USA); according to a study conducted in Makkah, by AL Mokarmah, the prevalence of FA among children attending the well-baby clinic was 22.5% and in Riyadh is 6% among children who visit the allergy clinic at King Khalid University Hospital. FA in children is usually caused by milk (2.5%), egg (1.3%), peanut (0.8%), tree nuts (0.2%), fish (0.1%), as well as shellfish (0.1%), with an overall prevalence of 6%. Methods: In this cross-sectional study, a self-administered questionnaire was used in the data collection. After data were collected, they were entered in the Statistical Software IBM SPSS version 22. Descriptive and inferential statistics were obtained. Results: Out of 980 mothers, 49% were suffering from food allergy, while 28.6% of their children were suffering from food allergy. Shellfish was the most common cause of food allergy (38%). Conclusion: The management of FA in children is improving through the acquisition of new knowledge in diagnosis and treatment. Education of physicians and food-allergic patients about FA and its treatment is becoming recognized as an unmet need. Key words: Food allergy, mother, children, knowledge, prevalence, factors

Food allergies, defined as an immune response to food proteins, affect as many as 8% of young children and 2% of adults in western countries, and their prevalence appears to be rising like all allergic diseases. In addition to well-recognized urticaria and anaphylaxis triggered by IgE antibody– mediated immune responses, there is an increasing recognition of cell-mediated disorders, such as eosinophilic esophagitis and food protein–induced enterocolitis. Non-IgE-Mediated gastrointestinal food allergies are a heterogeneous group of food allergies in which there is an immune reaction against food but the primary pathogenesis is not a production of IgE and activation of mast cells and basophils. Those diseases tend to affect mainly the gastrointestinal tract and can present as acute (FPIES) or chronic reaction, such as Eosinophilic Esophagitis (EoE), Food Protein-Induced Allergic Proctocolitis (FPIAP). The role of food allergy in Non-EoE gastrointestinal Eosinophilic disorders (Non- EoE EGID) is poorly understood. In some diseases like EoE, T cell seems to play a major role in initiating the immunological reaction against food, however, in FPIES and FPIAP, the mechanism of sensitization is not clear. Diagnosis requires food challenges and/or endoscopies in most of the patients, as there are no validated biomarkers that can be used for monitoring or diagnosis of Non-IgE mediated food allergies. The treatment of Non-IgE food allergy is dependent on diet (FPIES, and EoE) and/or use of drugs (i.e. steroids, PPI) in EoE and Non-EoE EGID. Non-IgE mediated food allergies are being being investigated.

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 The International Life Sciences Institute (ILSI) Europe Food Allergy Task Force was founded in response to early public concerns about the growing impact of food allergies almost coincidentally with the publication of the 1995 Food and Agriculture Organization-World Health Organization Technical Consultation on Food Allergies. In line with ILSI principles aimed to foster collaboration between stakeholders to promote consensus on science-based approaches to food safety and nutrition, the task force has played a central role since then in the development of risk assessment for food allergens. This ranged from consideration of the criteria to be applied to identifying allergens of public health concern through methodologies to determine the relationship between dose and the proportion of allergic individuals reacting, as well as the nature of the observed responses. The task force also promoted the application of novel, probabilistic risk assessment methods to better delineate the impact of benchmarks, such as reference doses, and actively participated in major European food allergy projects, such as EUROPREVALL, the European Union (EU)-funded project “The prevalence, cost and basis of food allergy across Europe;” and iFAAM, “Integrated approaches to food allergen and allergy risk management,” also an EU-funded project. Over the years, the task force’s work has evolved as answers to initial questions raised further issues: Its current work program includes a review of analytical methods and how different ones can best be deployed given their strengths and limitations. Another activity, which has just commenced, aims to develop a framework for stakeholders to achieve consensus on acceptable risk.

Background: In recent years, food allergy has been diagnosed more frequently in children and adolescents. The environment is more toxic and chemical substances that are additives to food dominate the diet. Also, a changing lifestyle, exposure to stress, and a poorly balanced diet may have an impact on the occurrence of allergies. In society, more children suffer from food allergies than adults, and food allergies are becoming an increasingly serious social and medical problem. Aim of the study: The aim of this study is to review the subject of food allergies in children, with a focus on the social and medical problems associated with this condition. Material and methods: 31 studies, published in the last 10 years, were found in databases such as the Polish Medical Bibliography, PubMed Medline, and Google Scholar, using the following keywords: “food allergy”, “risk factors”, “diet”, “psychology”, “social aspects”. Conclusions: Given the potentially serious medical and social consequences resulting from allergic diseases, the increasing incidence of allergies among children and young people should motivate medical personnel and educators to receive additional training and to conduct further research in this area.

Background: The prevalence of allergic disorders is on the rise, affecting about 10% of the population. In this retrospective cohort, we investigated prevalence of allergic disorders, associated risk factors, and the outcome of food allergies.  Material and methods: We analyzed data from birth cohorts of two university hospitals’ well-child outpatient clinics. Factors related to onset and type of allergic diseases were assessed from demographic, socioeconomic, and clinical data.  Results: Analyses were performed on 949 (431F/518M) infants at a mean current age of 28±6 months. Any allergic disease was established among 177 cases (22%); atopic dermatitis in 123 (12.8%), respiratory allergies in 55 (5.7%), and food allergy in 41 (4.3%). The risk for allergic disorders was found to be significantly increased for male gender (OR: 2.31, 95% CI; 1.54–3.46), and positive parental atopy (OR: 1.94, 95% CI; 1.31–2.86). The risk of food allergies was significantly higher in the male gender (OR: 2.47, 95% CI; 1.21–5.02), who consumed egg-white between 6 and 12 months (OR: 2.34, 95% CI; 1.22–4.48), and who were formula-fed before 6 months (OR: 2.16, 95% CI; 1.14–4.10). We found no significant association between the rate of food allergy outgrowth or food induced-anaphylaxis with regards to the timing of introducing egg-white into the diet.  Conclusions: Although the introduction of egg-white into infant diet at 6–12 months of life appeared as an independent risk for any food allergy, none of the patients developed anaphylaxis. Age at symptom onset and outgrowing food allergy were similar compared to those introduced egg-white after 12 months. We recommend promoting exclusive breastfeeding during the first 6 months of life, and avoidance of prolonged restrictive diets for children with food allergy.
