    Food allergy (FA) is a worldwide problem, with increasing prevalence in many countries, and it poses a clearly increasing health problem in Korea. In Korea, as a part of International Study of Asthma and Allergy in Childhood (ISAAC), a series of nation-wide population studies for prevalence of allergic disease in children were carried out, with the Korean version of ISAAC in 1995, 2000, and 2010. From the survey, the twelve-month prevalence of FA showed no significant differences from 1995 to 2000 in both age groups (6-12 years-old, 6.5% in 1995 and 5.7% in 2000; 12-15 year-olds, 7.4% in 1995 and 8.6% in 2000). The mean lifetime prevalence of FA which had ever been diagnosed by medical doctor was 4.7% in 6-12 year-olds and 5.1% in 12-15 year-olds respectively in 2000. In Korean children, the major causes of FA are almost same as in other countries, although the order prevalence may vary, a prime example of which being that peanut and tree nut allergies are not prevalent, as in western countries. Both pediatric emergency department (ED) visits and deaths relating to food induced anaphylaxis have also increased in western countries. From a study which based on data from the Korean Health Insurance Review and Assessment Service (KHIRA) from 2001 to 2007, the incidence of anaphylaxis under the age of 19 was 0.7-1 per 100,000 person-year, and foods (24.9%) were the most commonly identified cause of childhood anaphylaxis. In another epidemiologic study, involving 78889 patients aged 0-18 years who visited the EDs of 9 hospitals during June 2008 to Mar 2009, the incidence of food related anaphylaxis was 4.56 per 10,000 pediatric ED visits. From these studies, common causes of food related anaphylaxis were seafood, buckwheat, cow's milk, fruits, peanut and tree nuts. Although systematic epidemiologic studies have not reported on the matter, recently, plant foods related allergy has increased in Korean children.

  8. Use of Donkey Milk in Children with Cow’s Milk Protein Allergy

    Full Text Available Human breast milk is the best nutritional support that insures the right development and influences the immune status of the newborn infant. However, when it is not possible to breast feed, it may be necessary to use commercial infant formulas that mimic, where possible, the levels and types of nutrients present in human milk. Despite this, some formula-fed infant develops allergy and/or atopic disease compared to breast-fed infants. Cow’s milk allergy can be divided into immunoglobulin IgE mediated food allergy and non-IgE-mediated food allergy. Most infants with cow’s milk protein allergy (CMPA develop symptoms before 1 month of age, often within 1 week after introduction of cow’s milk-based formula. Donkey milk may be considered a good substitute for cow’s milk in feeding children with CMPA since its composition is very similar to human milk. Donkey milk total protein content is low (1.5–1.8 g/100 g, very close to human milk. A thorough analysis of the donkey milk protein profile has been performed in this study; the interest was focused on the milk proteins considered safe for the prevention and treatment of various disorders in humans. The content of lactoferrin, lactoperoxidase and lysozyme, peptides with antimicrobial activity, able to stimulate the development of the neonatal intestine, was determined. Donkey milk is characterized by a low casein content, with values very close to human milk; the total whey protein content in donkey milk ranges between 0.49 and 0.80 g/100 g, very close to human milk (0.68–0.83 g/100 g. Among whey proteins, α-lactalbumin average concentration in donkey milk is 1.8 mg/mL. The results of this study confirmed the possibility of using donkey milk in feeding children with CMPA.

    Since the 1930's the scientific literature on cow's milk protein allergy (CMPA) has accumulated. Over the last decade new diagnostic tools and treatment approaches have been developed. The diagnosis of reproducible adverse reactions to cow's milk proteins (CMP), i.e. CMPA, still has to be confirmed...... by controlled elimination and challenge procedures. Advanced diagnostic testing using epitope and microarray technology may in the future improve the diagnostic accuracy of CMPA by determination of specific IgE against specific allergen components of cow's milk protein. The incidence of CMPA in early childhood...... is approximately 2-3% in developed countries. Symptoms suggestive of CMPA may be encountered in 5-15% of infants emphasizing the importance of controlled elimination/milk challenge procedures. Reproducible clinical reactions to CMP in human milk have been reported in 0.5% of breastfed infants. Most infants...

    Conclusions: In Colombia, sensitization to milk and egg is relatively low compared to that reported in other studies with population with high risk of sensitization. Because of the association between sensitization of egg and the risk of having respiratory symptoms and gastrointestinal eosinophilia, an egg sensitization could be and early marker of poor prognosis in atopic patients.

  12. [Allergy to cow's milk].

    Fourrier, E

    1997-04-01

    After recalling the medical reluctance as well as the risks that there are in complete elimination of milk in infants, the author presents several clinical pictures and then a classification of the immunological types: Allergic shock of neonates, digestive and extra-digestive (skin and respiratory airways) symptoms finally the rare chronic gastro-enteritis to cow milk. Non-reaginic food allergies: Acute gastro-enteropathy to cow milk, with villous atrophy and Heiner's syndrome, delayed hypersensitivities are studied, of difficult diagnosis that may cover almost all pathologies. They may be found in the digestive system, respiratory, the kidneys and even in the organs of behaviour. Migraine of food origin must be remembered. Development in regressive rules is a function of the type of allergy and the suddenness of the symptoms. Diagnosis is above all by questioning and confirmation or not by skin and in vitro tests. Certainty can only be shown by tests of elimination and re-introduction. The diet, at the same time of both diagnostic and therapeutic value, is based on the replacement of cow milk by foods that contain the same amount of proteins. It is essential, especially in the very small, to have perfect match of food so as to avoid any risk of a dramatic hypoprotinemia, which may happen if the child does not like the suggested diet, or if the parents cannot buy the substitution products. In such conditions great care must be taken to avoid provoking a crisis. Care must be taken to decide: If the elimination of cow milk is always justified each time. If it is, always check that the substituted protein is properly made, the family may change the diet mistakenly.

    Cow's milk protein allergy (CMPA) is the first allergy that affects infants. In this population, the incidence rate reaches 7.5%. The multiplicity and aspecificity of the symptoms makes its diagnosis sometimes complicated, especially in the delayed type (gastrointestinal, dermatological, and cutaneous). CMPA symptoms can develop in exclusively breastfed infants with an incidence rate of 0.5%. It, therefore, raises questions about sensitization to cow's milk proteins through breast milk. Transfer of native bovine proteins such as β-lactoglobulin into the breast milk is controversial: some authors have found bovine proteins in human milk but others point to cross-reactivity between human milk proteins and cow's milk proteins. However, it seems that a small percentage of dietary proteins can resist digestion and become potentially allergenic. Moreover, some authors suspect the transfer of some of these dietary proteins from the maternal bloodstream to breast milk, but the mechanisms governing sensitization are still being studied. Theoretically, CMPA diagnosis is based on clinical observations, prick-test or patch-test results, and cow's milk-specific IgE antibody concentration. A positive food challenge test usually confirms the diagnosis. No laboratory test is available to make a certain diagnosis, but the detection of eosinophil cationic protein (ECP) in the mother's milk, for example, seems to be advantageous since it is linked to CMA. Excluding cow's milk from the mother's diet is the only cure when she still wants to breastfeed. Usually, cow's milk proteins are reintroduced after 6 months of exclusion. Indeed, the prognosis for infants is very good: 80% acquire a tolerance before the age of 3 or 4 years. Mothers should not avoid dairy products during pregnancy and breastfeeding as preventive measures against allergy. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Breast milk and colostrum are the first feeding sources for a child, providing nutrients, growth factors and immunological components, which are crucial for the newborn's correct development and health. Length of exclusive breastfeeding and time of solid foods introduction is a key factor that may influence allergy development. There is an emerging evidence of a relationship between breastfeeding, milk composition and lower risk of chronic diseases, such as diabetes, obesity, hypertension and allergies. This review examines current evidence regarding humoral and cellular characteristics of breast-milk, and potential role of environment, maternal diet and breastfeeding on the allergy development in children.

  15. Lactose intolerance and cow's milk protein allergy

    Adriano Henrique do Nascimento RANGEL

    Full Text Available Abstract Adverse reactions to food intake have very diverse etiology and symptomatology. Regarding milk, its food allergy is presented as lactose intolerance, the sugar in milk, or allergy to milk protein. Despite having different symptomatology, confusions among allergic conditions to dairy and its mediators are common. Milk protein allergy originates from protein components present in milk, causing reactions to either the protein fractions in emulsion (caseins or in whey (milk albumin. The allergic reaction is type IV mediated by T lymphocytes. The allergic reaction produces severe cellular damage and it triggers physical, mental and emotional symptomatology that may vary in time, intensity and severity. Lactose intolerance is originated by total or partial absence of the enzyme that digests this disaccharide. Lactose intolerance can be primary or congenital and secondary; the former being more rare and severe, the latter being more common. Lactase deficiency can be diagnosed by symptoms associated with cramping and diarrhea. Thus, the objective of this study was to conduct a review of available literature on cow’s milk protein allergy and lactose intolerance.

  16. Therapeutic modalities for cow's milk allergy.

    To discuss current therapeutic modalities for cow's milk allergy and its prevention. The sources of data include original clinical studies carried out at Ste. Justine Hospital, as well as a systematic search of the published English and French language scientific literature restricted to human subjects using computerized searches (National Public Library of Medicine, Cochrane Database Systems Review) from 1997 to 2002. Search terms for article retrieval included food allergy, milk allergy, therapy, and prevention. The therapy of food allergies depends upon an accurate diagnosis, which remains a challenge in non--IgE-mediated cases. Dietary exclusion remains the mainstay of therapy, with medications reserved for exceptional patients. Preliminary evidence suggests that pancreatic enzyme supplementation may be of benefit for cases with multiple food allergies and severe eczema. Hydrolysate formula use is currently recommended for dietary allergy prevention in infants at an increased risk when maternal milk is insufficient or unavailable. The use of partially hydrolyzed formulas to prevent allergic disorders, including atopic dermatitis, is supported by clinical studies, but cannot be used in the already sensitized, milk-allergic child. Probiotics show enormous potential in preventing food allergic disorders as well.

    Gut microbiota may play a role in the natural history of cow's milk allergy. We sought to examine the association between early-life gut microbiota and the resolution of cow's milk allergy. We studied 226 children with milk allergy who were enrolled at infancy in the Consortium of Food Allergy observational study of food allergy. Fecal samples were collected at age 3 to 16 months, and the children were followed longitudinally with clinical evaluation, milk-specific IgE levels, and milk skin prick test performed at enrollment, 6 months, 12 months, and yearly thereafter up until age 8 years. Gut microbiome was profiled by 16s rRNA sequencing and microbiome analyses performed using Quantitative Insights into Microbial Ecology (QIIME), Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt), and Statistical Analysis of Metagenomic Profiles (STAMP). Milk allergy resolved by age 8 years in 128 (56.6%) of the 226 children. Gut microbiome composition at age 3 to 6 months was associated with milk allergy resolution by age 8 years (PERMANOVA P = .047), with enrichment of Clostridia and Firmicutes in the infant gut microbiome of subjects whose milk allergy resolved. Metagenome functional prediction supported decreased fatty acid metabolism in the gut microbiome of subjects whose milk allergy resolved (η 2  = 0.43; ANOVA P = .034). Early infancy is a window during which gut microbiota may shape food allergy outcomes in childhood. Bacterial taxa within Clostridia and Firmicutes could be studied as probiotic candidates for milk allergy therapy. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

    Full Text Available Insulin, a crucial therapeutic agent for diabetes mellitus, has been rarely associated with hypersensitivity events. We present a 69-year-old type-2 diabetic patient with urticariform lesions on the sites of subcutaneous injection of insulin. The patient denied any known allergies, except for an unspecific cutaneous reaction after intramuscular penicillin administration in childhood. Prick tests revealed positive reactions to all tested human insulins and insulin analogues. Serum IgE levels were above normal range and RAST tests were positive for human, bovine and porcine insulins, as well as beta-lactams. Type 1 IgEmediated allergy to insulin analogues demands a prompt diagnosis and represents a significant therapeutic challenge in diabetic patients.A insulina é um agente indispensável para o controlo da diabetes mellitus. Os efeitos adversos da sua administração, em particular fenómenos de hipersensibilidade, são raros.

    Food allergy is a rare disorder among breastfeeding babies. Our aim was to identify responsible allergens in human milk. We studied babies developing allergic symptoms at the time they were breastfeeding. Skin prick tests (SPT) were performed with breast milk and food allergens. Specific IgE was assessed and IgE Immunoblotting experiments with breast milk were carried out to identify food allergens. Clinical evolution was evaluated after a maternal free diet. Five babies had confirmed breast milk allergy. Peanut, white egg and/or cow's milk were demonstrated as the hidden responsible allergens. No baby returned to develop symptoms once mother started a free diet. Three of these babies showed tolerance to other food allergens identified in human milk. A maternal free diet should be recommended only if food allergy is confirmed in breastfed babies.

A significant association between early neonatal exposure to cow's milk formula...... feeding and subsequent development of CMPA/CMPI has been documented. The small amounts of 'foreign' protein in human milk may rather induce tolerance than allergic sensitization. The findings of specific IgE to individual cow's milk proteins in cord blood of the majority of infants who later develop CMPA...... with an early increased IgE response to cow's milk protein have an increased risk of persisting CMPA, development of persistent adverse reactions to other foods and development of allergy against environmental inhalant allergens.

    Full Text Available Abstract A joint study group on cow's milk allergy was convened by the Emilia-Romagna Working Group for Paediatric Allergy and by the Emilia-Romagna Working Group for Paediatric Gastroenterology to focus best practice for diagnosis, management and follow-up of cow's milk allergy in children and to offer a common approach for allergologists, gastroenterologists, general paediatricians and primary care physicians. The report prepared by the study group was discussed by members of Working Groups who met three times in Italy. This guide is the result of a consensus reached in the following areas. Cow's milk allergy should be suspected in children who have immediate symptoms such as acute urticaria/angioedema, wheezing, rhinitis, dry cough, vomiting, laryngeal edema, acute asthma with severe respiratory distress, anaphylaxis. Late reactions due to cow's milk allergy are atopic dermatitis, chronic diarrhoea, blood in the stools, iron deficiency anaemia, gastroesophageal reflux disease, constipation, chronic vomiting, colic, poor growth (food refusal, enterocolitis syndrome, protein-losing enteropathy with hypoalbuminemia, eosinophilic oesophagogastroenteropathy. An overview of acceptable means for diagnosis is included. According to symptoms and infant diet, three different algorithms for diagnosis and follow-up have been suggested.

    Full Text Available There are controversies on the association of childhood allergic diseases with inflammatory bowel diseases (IBD. The aim of this study was to examine the association between food allergy, cow’s milk allergy (CMA, and asthma with pediatric IBD in Iranian population. This case-control study was conducted on 200 individuals less than 18-year-old (100 with IBD and 100 as control group. Medical records, clinical presentation, and laboratory and para-clinical findings related to food allergy, CMA, and asthma were reviewed for all participants in both groups and were recorded. Among 100 children with IBD, 40 had Crohn's disease, and 60 had ulcerative colitis. The frequency of food allergy, cow's milk allergy, and asthma in children with IBD was significantly higher than the control group (P<0.001. Asthma in children with Crohn's disease was significantly more prevalent than children with ulcerative colitis (P=0.008. Food allergy (OR: 22.1, 95% CI: 5.1-95.05, P<0.001, CMA (OR: 15, 95% CI: 3-67, P<0.001, and asthma (OR: 10, 95% CI: 3-37.05, P<0.001 were significantly associated with increased risk of IBD in children. Food allergy, CMA in infancy and asthma are more prevalent in children with different subtypes of IBD. The diagnosis of these risk factors is associated with increased risk of Crohn's disease and ulcerative colitis.

    Cow's milk protein allergy is the most common cause of food allergy. The challenge test, either open or doubled-blind with a placebo control, is regarded as the criterion standard. Endoscopy and histologic findings are considered a method that can aid in the diagnosis of this entity. The aim of this study was to describe the histopathologic findings in children suspected of cow's milk protein allergy that were seen at our hospital. A descriptive, observational study was conducted on 116 children clinically suspected of presenting with cow's milk protein allergy that were seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría. Upper endoscopy and rectosigmoidoscopy with biopsies were performed and the findings were described. Of the 116 patients, 64 (55.17%) were girls and 52 (44.83%) were boys. The rectum was the site with the greatest presence of eosinophils per field in both groups, followed by the duodenum. In general, more than 15 eosinophils were found in 46% of the patients. Between 40 and 45% of the cases had the histologic criterion of more than 15 to 20 eosinophils per field and the rectosigmoid colon was the most affected site. Therefore, panendoscopy and rectosigmoidoscopy with biopsy and eosinophil count are suggested. Copyright © 2014 Asociación Mexicana de Gastroenterología. Published by Masson Doyma México S.A.

    Children that grow up on farms have fewer allergies than children growing up in city environments. This protection against the development of allergy is associated with the consumption of raw farm milk. Heated farm milk does not have this effect, indicating that (non-denatured) milk proteins are

    This guideline advises on the management of patients with cow's milk allergy. Cow's milk allergy presents in the first year of life with estimated population prevalence between 2% and 3%. The clinical manifestations of cow's milk allergy are very variable in type and severity making it the most difficult food allergy to diagnose. A careful age- and disease-specific history with relevant allergy tests including detection of milk-specific IgE (by skin prick test or serum assay), diagnostic elimination diet, and oral challenge will aid in diagnosis in most cases. Treatment is advice on cow's milk avoidance and suitable substitute milks. Cow's milk allergy often resolves. Reintroduction can be achieved by the graded exposure, either at home or supervised in hospital depending on severity, using a milk ladder. Where cow's milk allergy persists, novel treatment options may include oral tolerance induction, although most authors do not currently recommend it for routine clinical practice. Cow's milk allergy must be distinguished from primary lactose intolerance. This guideline was prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI) and is intended for clinicians in secondary and tertiary care. The recommendations are evidence based, but where evidence is lacking the panel of experts in the committee reached consensus. Grades of recommendation are shown throughout. The document encompasses epidemiology, natural history, clinical presentations, diagnosis, and treatment. © 2014 John Wiley & Sons Ltd.

  16. New guidelines for managing cow's milk allergy in infants.

    Science.gov (United States)

    2008-01-01

    The prevalence of allergic disease has increased markedly over the last 50 years. Food allergy usually manifests in early childhood as part of the so-called atopic march and most commonly includes one or more of the following foods: cow's milk, hen's egg, soy, peanuts and tree nuts, wheat, sesame seed, kiwi fruit and seafood. In the UK about 2% of infants develop cow's milk protein allergy (CMPA), but as many as 15% of infants present with symptoms suggestive of an adverse reaction to cow's milk protein. The diagnosis of CMPA is based on one or more of the following: a detailed clinical history, allergy test results (skin prick testing [SPT] and/or specific immunoglobulin E [IgE]) and, if required, supervised incremental milk challenges. The majority of UK primary care centres do not have access to these tests and may also be unfamiliar with the interpretation or results. In addition, they do not have the facilities for supervised food challenges. Empirical treatment is often required pending confirmation of allergy or referral to a specialist centre, but requires clear guidelines. No consensus guidelines currently exist for the diagnosis and management of CMPA in the UK. An international task force has recently published proposed guidelines for the management of CMPA. These provide separate algorithms covering the diagnosis and management of CMPA for both breast-fed and formula-fed infants and discuss the use of hypoallergenic formulae, elimination diets and diagnostic tests. Revisions and adaptations for the UK market are required and are discussed in this article.

    Full Text Available Allergies become more common nowadays because of numerous risk factors and better medical resources for diagnostics. So, it is imperative to have at least an idea how to control them rather than treating them. A proper diet for an allergy may prevent it to be clinically significant and improve the patient’s life quality and symptoms. Milk allergy is one of the most common ones together with gluten and soy allergies. Older children and adults are easy to manage because they can communicate, and they eat almost everything. But the problem occurs especially in young infants, the most challenging ones because milk is vital for their survival and development. In the following article, we will try to highlight its particularities and explain what a patient with this condition should eat, taking into consideration processed food, found nowadays in every supermarket. We will detail what is allowed what is not allowed to consume, so this kind of a diet should be easy to prescribe by any nutritionist and easy to follow by every patient.

    We wanted to evaluate the barium enema findings of milk allergy in infants. Retrospective evaluation of the plain abdominal radiography and barium enema findings was performed in fifteen young infants suffering with milk allergy. The presence of gaseous distension, rectal gas, paralytic ileus and mechanical obstruction was evaluated on the plain radiography. The presence of spasm, a transitional zone, a reversed rectosigmoid index and mucosal irregularity was analyzed on the barium enema; the presence of barium retention was also evaluated on 24-hour-delayed plain radiography. Paralytic ileus was the most common finding on the plain radiography (93%). On the barium enema, continuous spasm of the colon, ranging from the rectum to the descending colon, was revealed in ten infants (67%). A transitional zone was observed in one infant and a reversed rectosigmoid index was revealed in four. Mucosal irregularity was observed in two infants. Barium retention was demonstrated in 11 of fifteen cases: throughout the entire colon (n = 3), from the rectum to the descending colon (n = 7), and up to the transverse colon (n = 1). The most common barium enema finding of milk allergy in infants was spasm of the distal colon. The other findings were a transitional zone, a reversed rectosigmoid index, mucosal irregularity and barium retention

    Food allergy is an increasing health problem in the developed world. Cow's milk protein is the main cause of food allergy in infants. Without an appropriate diagnostic workup, there is a high risk of both over- and underdiagnosis and therefore, over and undertreatment. The objective of our study was to analyze the variability in cow's milk protein allergy (CMPA) management by pediatric gastroenterologists in Spain. A fifty item questionnaire, including open and closed items in a Likert's scale from 0 to 5, was drafted and distributed through the Spanish Society for Pediatric Gastroenterology, Hepatology and Nutrition (SEGHNP) e-mail list. Seventy-three questionnaires were received back out of 321. Only 3 of the items achieved concordance greater than 90%. Thirty-three percent considered oral challenge to be necessary for the diagnosis of CMPA under any circumstance. Twenty-five percent considered that symptom improvement after cow's milk removal was enough for the diagnosis. Oral challenge was performed at home by 83.5% in non-IgE mediated cases. Extensively hydrolyzed casein formulas were the treatment of choice for 69.9%. Soy formulas were the last option. Almost all respondents were aware of the existence of clinical guidelines on CMPA, being European Society of Pediatric Gastroenterology, Hepatology and Nutrition guidelines the most followed (64.4%). Twenty-three percent considered that their knowledge about allergy was inadequate. Although CMPA is a prevalent condition that pediatric gastroenterologists have been treating for decades, we found a huge variability on its management. There is potential for improvement in this field among pediatric gastroenterologist in the future. Copyright © 2017. Publicado por Elsevier España, S.L.U.

    Cow's milk allergy (CMA) is the most common food allergy in infancy. Food allergy is generally triggered through ingestion, but can also be triggered through skin contact. We investigated the incidence and the clinical significance of cow's milk protein (CMP)-induced contact urticaria in individuals with CMA with and without atopic dermatitis (AD). A total of 157 children of whom 133 were diagnosed with CMA were participated. The study was based on observational data gathered in the course of patient care, including a skin prick test and a 'finger test', in which cow's milk is applied on the cheek by a physician's finger to detect contact urticaria. Eighty nine of 133 patients (66.9%) had IgE-mediated CMA. Forty of these 89 (44.9%) tested positive in the finger test. Family atopy was higher in those with positive contact urticaria [21/40 (52.5%) vs. 14/49 (28.5%), p = 0.029]. Patients with positive vs. negative CMP contact urticaria had higher incidence of multiple food allergies [20 of 40 (50%) vs. 7/49 (14.3%), p milk allergy and healthy control group did not have contact urticaria to CMP. CMP contact urticaria exists only in patients with IgE-mediated CMA. A 'finger test' to CMP should be part of the evaluation of CMA patients, and positivity suggests the potential for multiple food allergies, especially to sesame and egg. © 2015 John Wiley & Sons A/S.

    Full Text Available Cow’s milk protein allergy (CMPA is the leading cause of food allergy in children under three years of age, although its gastrointestinal manifestations may occur in all age groups. In the suspicion of CMPA based on the anamnesis and physical examination, an elimination diet should be initiated for a variable length of time according to the clinical picture, followed by an oral food challenge (OFC confi rming or excluding the diagnosis. Complementary exams such as skin prick tests and specifi c IgE may be necessary. Treatment is based on an elimination diet and demands nutritional counselling and growth monitoring. Usually an OFC is repeated after three to 12 months of elimination diet. Tolerance is achieved at three years of age in more than 80% of the children. The aim of this work is to make a brief review and update on CMPA in pediatric age, proposing a management approach based on recent international recommendations.

    In 2010, the diagnosis and treatment of IgE-mediated CMA were systematized in a GRADE guideline. After 6 years, the state of the knowledge in diagnosis and treatment of CMA has largely evolved. We summarize here the main advances, and exemplify indicating some specific points: studies aimed at better knowledge of the effects of breastfeeding and the production of new special formulae intended for the treatment of CMA. The literature (PubMed/MEDLINE) was searched using the following algorithms: (1) [milk allergy] AND diagnosis; (2) [milk allergy] AND [formul*] OR [breast*], setting the search engine [6-years] time and [human] limits. The authors drew on their collective clinical experience to restrict retrieved studies to those of relevance to a pediatric allergy practice. Several clinical studies did address the possibility to diagnose CMA using new tools in vitro and in vivo, or to diagnose it without any evaluation of sensitization. Some studies also addressed the clinical role of formulae based on milk hydrolysates, soy, or rice hydrolysates in the treatment of CMA. Many studies have elucidated the effects of selective nutrients in breastfed infants on their immunologic and neurologic characteristics. Evidence-based diagnostic criteria should be identified for non-IgE-mediated CMA. Debate is ongoing about the best substitute for infants with CMA. In particular, Hydrolyzed Rice Formulae have been widely assessed in the last six years. In the substitute choice, clinicians should be aware of recent studies that can modify the interpretation of the current recommendations. New systematic reviews and metanalyses are needed to confirm or modify the current DRACMA recommendations.

    2014-01-01

    Full Text Available Food allergy is an aberrant immune-mediated reaction against harmless food substances, such as cow’s milk proteins. Due to its very early introduction, cow’s milk allergy is one of the earliest and most common food allergies. For this reason cow’s milk allergy can be recognized as one of the first indications of an aberrant inflammatory response in early life. Classically, cow’s milk allergy, as is true for most other allergies as well, is primarily associated with abnormal humoral immune responses, that is, elevation of specific immunoglobulin E levels. There is growing evidence indicating that cellular components of both innate and adaptive immunity play significant roles during the pathogenesis of cow’s milk allergy. This is true for the initiation of the allergic phenotype (stimulation and skewing towards sensitization, development and outgrowth of the allergic disease. This review discusses findings pertaining to roles of cellular immunity in allergic inflammation, and tolerance induction against cow’s milk proteins. In addition, a possible interaction between immune mechanisms underlying cow’s milk allergy and other types of inflammation (infections and noncommunicable diseases is discussed.

    Cow's milk protein allergy (CMPA) is frequently suspected in infants with a variety of symptoms. A thorough history and careful clinical examination are necessary to exclude other underlying diseases and to evaluate the severity of the suspected allergy. Care should be taken to diagnose CMPA adequately to avoid an unnecessary diet. We make recommendations based on systematic literature searches using the best-available evidence from PubMed, Cumulative Index to Nursing and Allied Health Literature, and bibliographies. Skin prick tests, patch tests and serum specific IgE are only indicative of CMPA. Breastfed infants have a decreased risk of developing CMPA; an elimination diet for the mother is indicated if CMPA is confirmed. If a food challenge is positive in formula fed infants, an extensively hydrolysed formula and cow's milk-free diet is recommended. If symptoms do not improve, an amino acid based formula should be considered. In severe CMPA with life-threatening symptoms, an amino-acid formula is recommended. Elimination diet by a double-blind placebo controlled food challenge is the gold standard for diagnosis. Elimination of the offending allergen from the infants' diet is the main treatment principle.

    Cow's milk allergy (CMA) epidemiology seems to be changing over time, with an increase in prevalence and persistence. Our aim was to characterise a population of children with CMA beyond two years of age, followed up in a Paediatric Allergy Clinic at the tertiary care level. Retrospective study of children with persistent CMA diagnosed from January 1997 to June 2006. Medical records were analysed regarding: clinical presentation, follow-up, treatment and acquisition of tolerance. Data analysis was performed using Excel 2007 for Windows. Seventy-nine children were included, with mean age at first symptoms of 3 months. The symptoms were immediate in 93%, with cutaneous (87.3%), gastrointestinal (55.7%) and respiratory (25.3%) manifestations. During the follow-up period, 30% developed atopic eczema, 52% asthma and 35% rhinoconjunctivitis. A family history of atopy was identified in 53%. The majority presented increased serum total IgE (376+/-723 KU/l) and positive skin prick test (SPT) to cow's milk (CM) (79%). SPT to goat's milk was positive in 2/3 of cases. Fifty-five percent had at least one accidental exposure to CM (severe reactions in 6%). During CM elimination diet, 35% were initially given an extensively hydrolysed formula, 17% a soy formula, and 48% both. By the age of 10 years, 44% of children persisted with CMA. Our population of CM allergic children presented immediate symptoms with cutaneous expression in the majority. Severe reactions were common on accidental exposure. By the age of 10 years, 44% maintained CMA, highlighting the importance of a multidisciplinary follow-up. Copyright 2009 SEICAP. Published by Elsevier Espana. All rights reserved.

    Food hypersensitivity (FHS) is the umbrella term used to describe both food allergy, which involves the immune system, and food intolerances, which do not. It is therefore important that the diagnosis is made by a specialist health care professional such as a paediatrician or allergist. Some experienced dietitians and health visitors may be able to assist in making a diagnosis. The diagnostic work-up includes a medical history and blood tests/skin tests (where applicable). A food and symptom diary followed by a special test diet to identify the foods causing the infant's symptoms may also be needed. Once a diagnosis is made, dietary advice should be given to eliminate or reduce the intake of the offending foods. For cow's milk hypersensitivity in infants, this will include choosing the most appropriate specialised infant formula.

    Food allergy is defined as an adverse immune response towards food proteins or as a form of a food intolerance associated with a hypersensitive immune response. It should also be reproducible by a double-blind placebo-controlled food challenge. Many reported that food reactions are not allergic but are intolerances. Food allergy often presents to clinicians as a symptom complex. This review focuses on the clinical spectrum and manifestations of various forms of food allergies. According to clinical presentations and allergy testing, there are three types of food allergy: IgE mediated, mixed (IgE/Non-IgE), and non-IgE mediated (cellular, delayed type hypersensitivity). Recent advances in food allergy in early childhood have highlighted increasing recognition of a spectrum of delayed-onset non-IgE-mediated manifestation of food allergy. Common presentations of food allergy in infancy including atopic eczema, infantile colic, and gastroesophageal reflux. These clinical observations are frequently associated with food hypersensitivity and respond to dietary elimination. Non-IgE-mediated food allergy includes a wide range of diseases, from atopic dermatitis to food protein-induced enterocolitis and from eosinophilic esophagitis to celiac disease. The most common food allergies in children include milk, egg, soy, wheat, peanut, treenut, fish, and shellfish. Milk and egg allergies are usually outgrown, but peanut and treenut allergy tends to persist. The prevalence of food allergy in infancy is increasing and may affect up to 15-20 % of infants. The alarming rate of increase calls for a public health approach in the prevention and treatment of food allergy in children.

    The prevalence of asthma and allergic diseases in childhood has increased in several industrialized countries since the second half of the twentieth century. In some countries, the prevalence is still rising, although in others it seems to have plateaued or even decreased. It has been suggested that environmental factors operating prenatally and in early life affect the development of asthma and allergic diseases. Particularly changes in microbial exposure are proposed to play an important role in the development and maturation of the immune system. Thus, the factors that affect microbial exposure, such as mode of delivery and the use of antibiotics, may influence the development of asthma and allergic diseases. Several studies have explored the associations between perinatal factors and children's use of antibiotics and the risk of asthma, with inconsistent findings. The present review article will be focused on the important findings related with factors responsible for above allergic reactions along with asthma in young infants. Also, the influence of cow milk intake will also be taken in account to cover the aspect of cow milk induced allergies and asthma in infants.

    The necessity of milk consumption in the western diet is a subject of intense controversy. One of the main benefits of milk is that it is the main source of dietary calcium. Calcium is a major bone mineral, mandatory for bone health. Its supply is derived exclusively from external dietary sources. During the growth period, an increased calcium supply is needed for the process of bone mass accumulation. An optimal bone mass achieved by the end of the growth period may be protective later in life against the bone mass loss that commonly occurs. This in turn, can be preventative against the occurrence of osteoporosis and the development of spontaneous bone fractures. Over the past several decades, an increased incidence of osteoporosis has been documented in western countries, leading to high rates of morbidity and mortality in the middle-aged and geriatric population. Many studies have investigated the dietary calcium requirements for different ages, to achieve and maintain proper bone health. Based on their results, guidelines concerning calcium intake in every stage of life have been published by national and international organizations. In the western diet, it is difficult to achieve the recommended calcium intake without milk consumption. Moreover, calcium bioavailability for intestinal absorption is high. Several studies have recently raised doubts concerning the amounts of calcium intake in the western diet and its effectiveness in preventing osteoporosis. The main disadvantage of these studies is their being based on the patient's past memory recall of milk consumption. Patients with IgE-mediated cow's milk protein allergy are a unique population. Their lifetime negligible milk consumption is undisputed. A recent study investigated for the first time, the bone density of young adults with milk allergy at the end of their growth period. Their severe reduction in bone mineral density and dietary calcium intake defines them as a high risk group for the

    Heat treatment of several foods, including all types of cooking, has been mainly used to minimize the number of viable microbes, reduce pathogenicity, and destroy the undesirable enzymes, maintaining food quality. In addition, food processing improves sensory, nutritional, and physical properties of the foods, due to food protein denaturation. Heat-induced alterations of food proteins can attenuate allergenicity. In this article, the authors review the important role of thermal processing on milk and egg proteins, which comprise the commonest food allergies in infancy and early childhood.

    The aim of this study has been to clarify the immunopathogenesis and diagnosis of cow milk allergy (CMA). Thirty-four children with symptoms suggestive of CMA had a challenge test with cow milk (CM) and an estimation of their immunological response. Nineteen of the 34 children reacted to CM challenge test. We measured serum levels of immunoglobulins G, A, M and E, complement fractions 3 and 4, class specific CM antibodies as well as the numbers of the different lymphocyte subsets and the responses of lymphocytes in whole blood to stimulation by phytohemagglutinin (PHA), concanavalin A (ConA) and beta-lactoglobulin (BLG). Twelve (63%) of the children who reacted had high levels of IgE CM-specific antibodies; they had lower mean levels of serum IgA and lower lymphocyte stimulation indices with BLG and PHA than the rest of the children (37%) who reacted on CM, but were without IgE antibodies. Of these seven children, five gave elevated responses to stimulation with BLG, and in three of six the helper/suppressor lymphocyte ratio rose during the challenge test. Most (10) of 15 children who showed no reaction when challenged with CM at hospital, had earlier had cutaneous symptoms closely related to CM formula feeding. No single laboratory method was sufficient to discriminate between the children who reacted to CM and those who did not. The best combination of tests was measurements of CM-specific IgE and the index of lymphocyte stimulation with BLG. This combination had a sensitivity of 88% and specificity of 67% for predicting a clinical reaction.

    Psychiatric disorders are seen frequently in atopic diseases. The present study aims to evaluate the frequency of psychiatric disorders and the severity of psychiatric symptoms in pre-school children with cow's milk allergy. The parents of the pre-school children with cow's milk allergy were interviewed in person and asked to fill out the Early Childhood Inventory-4 form. The cow's milk allergy group included 40 children (27 male, 13 female) with mean age, 44.5±14.7 months, and the control group included 41 children (25 male, 16 female) with mean age, 47.6±15.2 months. It was established that 65% of the group with cow's milk allergy received at least one psychiatric diagnosis, while 36.6% of the control group received at least one psychiatric diagnosis, with a statistically significant difference (p=0.02). Within the psychiatric disorders, attention deficit hyperactivity disorders (odds ratio: 4.9, 95% CI: 1.472-16.856, p=0.006), oppositional defiant disorder (odds ratio: 5.6, 95% CI: 1.139-28.128, p=0.026), and attachment disorder (odds ratio: 4.8, 95% CI: 1.747-13.506, p=0.004) were found significantly higher compared with the healthy control group. When the groups were compared in terms of psychiatric symptom severity scores, calculated by using the Early Childhood Inventory-4 form, attention deficit hyperactivity disorders severity (p=0.006) and oppositional defiant disorder severity (p=0.037) were found to be higher in the cow's milk allergy group. Psychiatric disorders are frequent and severe in pre-school children with cow's milk allergy. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U. All rights reserved.

    Full Text Available Abstract Background Intestinal malrotation is an incomplete rotation of the intestine. Failure to rotate leads to abnormalities in intestinal positioning and attachment that leave obstructing bands across the duodenum and a narrow pedicle for the midgut loop, thus making it susceptible to volvulus. One of the important differential diagnoses for malrotation is an allergy to cow’s milk. Several studies have described infants with surgical gastrointestinal diseases and cow’s milk allergy. However, to our knowledge, no study has reported infants with intestinal malrotation who have been symptomatic before surgery was performed and have been examined by allergen-specific lymphocyte stimulation test and food challenge tests with long-term follow-up. Case presentation The patient was a Japanese male born at 39 weeks of gestation. He was breast-fed and received commercial cow’s milk supplementation starting the day of birth and was admitted to our hospital at 6 days of age due to bilious vomiting. Plain abdominal radiography showed a paucity of gas in the distal bowel. Because we demonstrated malpositioning of the intestine by barium enema, we repositioned the bowel in a normal position by laparotomy. The patient was re-started on only breast milk 2 days post surgery because we suspected the presence of a cow’s milk allergy, and the results of an allergen-specific lymphocyte stimulation test showed a marked increase in lymphocyte response to kappa-casein. At 5 months of age, the patient was subjected to a cow’s milk challenge test. After the patient began feeding on cow’s milk, he had no symptoms and his laboratory investigations showed no abnormality. In addition, because the patient showed good weight gain and no symptoms with increased cow’s milk intake after discharge, we concluded that the present case was not the result of a cow’s milk allergy. At 1 year, the patient showed favorable growth and development, and serum allergy

    The aim of this study was to evaluate the safety and efficacy of oral rush desensitization in children with cow milk allergy. Prospective study. We included IgE-mediated cow milk allergy children over 3 years in 3 Spanish hospitals. Increasing doses of cow milk for 5 days from 1 cc of 1% to 200 cc of pure milk were administered. Clinical follow-up was conducted and we compared specific IgE levels at onset, 6, 12 and 24 months after desensitization. We included 18 children (13 males) between 3 and 14 years (mean 5.96). A total of 271 doses were administered; there were 55 adverse reactions (84% mild). At the end of the protocol, 100% showed some degree of tolerance (39% total). Full tolerance was achieved in 72% of patients after two years. Two children failed to achieve tolerance. There was a significant decrease in the levels of specific IgE to cow milk and alpha-lactalbumin at 24 months, and to casein at 6, 12 and 24 months, compared to baseline. Oral rush desensitization is a safe and effective therapeutic option for patients with persistent cow milk allergy to medium term. Copyright © 2012 Asociación Española de Pediatría.

    Maternal diet during pregnancy may affect childhood allergy and asthma. We sought to examine the associations between maternal intake of common childhood food allergens during early pregnancy and childhood allergy and asthma. We studied 1277 mother-child pairs from a US prebirth cohort unselected for any disease. Using food frequency questionnaires administered during the first and second trimesters, we assessed maternal intake of common childhood food allergens during pregnancy. In mid-childhood (mean age, 7.9 years), we assessed food allergy, asthma, allergic rhinitis, and atopic dermatitis by questionnaire and serum-specific IgE levels. We examined the associations between maternal diet during pregnancy and childhood allergy and asthma. We also examined the cross-sectional associations between specific food allergies, asthma, and atopic conditions in mid-childhood. Food allergy was common (5.6%) in mid-childhood, as was sensitization to at least 1 food allergen (28.0%). Higher maternal peanut intake (each additional z score) during the first trimester was associated with 47% reduced odds of peanut allergic reaction (odds ratio [OR], 0.53; 95% CI, 0.30-0.94). Higher milk intake during the first trimester was associated with reduced asthma (OR, 0.83; 95% CI, 0.69-0.99) and allergic rhinitis (OR, 0.85; 95% CI, 0.74-0.97). Higher maternal wheat intake during the second trimester was associated with reduced atopic dermatitis (OR, 0.64; 95% CI, 0.46-0.90). Peanut, wheat, and soy allergy were each cross-sectionally associated with increased childhood asthma, atopic dermatitis, and allergic rhinitis (ORs, 3.6 to 8.1). Higher maternal intake of peanut, milk, and wheat during early pregnancy was associated with reduced odds of mid-childhood allergy and asthma.

    To verify whether infants with cow's milk protein allergy have inadequate vitamin D levels. This cross-sectional study included 120 children aged 2 years or younger, one group with cow's milk protein allergy and a control group. The children were recruited at the pediatric gastroenterology, allergology, and pediatric outpatient clinics of a university hospital in the Northeast of Brazil. A questionnaire was administered to the caregiver and blood samples were collected for vitamin D quantification. Vitamin D levels <30ng/mL were considered inadequate. Vitamin D level was expressed as mean and standard deviation, and the frequency of the degrees of sufficiency and other variables, as proportions. Infants with cow's milk protein allergy had lower mean vitamin D levels (30.93 vs.35.29ng/mL; p=0.041) and higher deficiency frequency (20.3% vs.8.2; p=0.049) than the healthy controls. Exclusively or predominantly breastfed infants with cow's milk protein allergy had higher frequency of inadequate vitamin D levels (p=0.002). Regardless of sun exposure time, the groups had similar frequencies of inadequate vitamin D levels (p=0.972). Lower vitamin D levels were found in infants with CMPA, especially those who were exclusively or predominantly breastfed, making these infants a possible risk group for vitamin D deficiency.

    Adverse reactions to foods are extremely common, and generally they are attributed to allergy. However, clinical manifestations of various degrees of severity related to ingestion of foods can arise as a result of a number of disorders, only some of which can be defined as allergic, implying an immune mechanism. Recent epidemiological data in North America showed that the prevalence of food allergy in children has increased. The most common food allergens in the United States include egg, milk, peanut, tree nuts, wheat, crustacean shellfish, and soy. This review examines the various forms of food intolerances (immunoglobulin E [IgE] and non-IgE mediated), including celiac disease and gluten sensitivity. Immune mediated reactions can be either IgE mediated or non-IgE mediated. Among the first group, Immediate GI hypersensitivity and oral allergy syndrome are the best described. Often, but not always, IgE-mediated food allergies are entities such as eosinophilic esophagitis and eosinophilic gastroenteropathy. Non IgE-mediated immune mediated food reactions include celiac disease and gluten sensitivity, two increasingly recognized disorders. Finally, non-immune mediated reactions encompass different categories such as disorders of digestion and absorption, inborn errors of metabolism, as well as pharmacological and toxic reactions.

    The Sabin vaccine is used world-wide, and most children with food allergies receive it without incident. However, in the 2009 vaccination campaign conducted in Argentina, four children experienced immediate-type hypersensitivity reactions following vaccination. We aimed to review the medical history of the affected children, study their allergic condition after the episodes and analyse the presence of allergenic vaccine components. Patients were selected based on their immediate allergic reactions following vaccination. They were assessed for allergies to cow's milk and hen's egg. The presence of cow's milk proteins in the vaccine was tested by various immunoassays involving cow's milk- or α-lactalbumin-specific polyclonal rabbit antiserum and patient sera. All of the patients had a history of milk allergy, and no history or current evidence of egg hypersensitivity was found. Levels of cow's milk- and Sabin vaccine-specific IgE were increased, and the result of a skin prick test with cow's milk proteins or the Sabin vaccine was positive in each patient. In addition, an ELISA using specific rabbit antiserum detected α-lactalbumin in the Sabin vaccine. When α-lactalbumin was employed as a soluble inhibitor in a competitive ELISA, binding to vaccine-coated plates by cow's milk- or α-lactalbumin-specific rabbit antiserum or by patient serum containing IgE was inhibited. We have demonstrated that these patients were allergic to cow's milk, and had circulating and mast cell-bound IgE antibodies specific to cow's milk proteins. We found that the Sabin vaccine contained α-lactalbumin, which may have been responsible for the reactions elicited following vaccination with the Sabin and dual viral vaccines in combination. © 2012 Blackwell Publishing Ltd.

    Food allergy is common in children and young adults and may be difficult to diagnose and is at present treated with avoidance of the food in question. The aim of this report is to share our clinical experiences monitoring omalizumab treatment by basophil allergen threshold sensitivity, CD-sens. Five children, 6-16 years of age, with a severe milk allergy including episodes of anaphylaxis and IgE-antibodies, between 30 and 160 kUA/L to casein and alpha-lactalbumin (milk proteins), were treated with omalizumab. CD-sens, was tested prior to and after 4 months of omalizumab and if turned negative, it was followed by an oral milk challenge. All children became negative in CD-sens and had a negative milk challenge, but one child required doubling of the omalizumab dose to achieve a negative CD-sens before a challenge was done. Omalizumab appears useful in treatment of severe food allergy, e.g., anaphylaxis to milk, and CD-sens monitoring may decide when and how to perform a food challenge.

    This article describes the case of a 16-month-old Hispanic male toddler with cow's milk allergy living in northern California who was admitted to a children's hospital for weight loss and markedly elevated levels of serum alkaline phosphatase and parathyroid hormone. At a routine outpatient well-child visit, his mother expressed concern about a decrease in his appetite and activity level. A detailed diet history revealed that breast milk was his primary source of nutrition during his first year of life and he had not been given supplemental vitamins. With attempts to introduce cow's milk formula, he had developed a rash and swelling around the mouth. Shortly after his first birthday, his mother weaned him from breast milk and introduced unfortified rice milk as a palatable milk substitute. Upon admission he was pale and lethargic; his laboratory studies were remarkable for elevated serum alkaline phosphatase and parathyroid hormone and low levels of phosphorus, 25-hydroxy-vitamin D, and ferritin. Lower extremity radiographic studies were consistent with rickets. After 5 weeks of therapy with vitamin D(3) and iron, his serum 25-hydroxy-vitamin D level normalized. Within 12 weeks following therapy, the child demonstrated significant clinical improvement, with resolution of growth failure and bone reossification. His activity level had returned to normal. This case emphasizes the importance of adequate vitamin D intake for children with special attention to those who might have nutrition deficiencies attributable to milk allergy.

    Occasionally, exclusively breastfed infants with cow's milk allergy (CMA) remain symptomatic despite strict maternal milk avoidance. To determine whether or not persistence of symptoms could be due to sensitization against endogenous human milk proteins with a high degree of similarity to bovine allergens. Ten peptides representing known bovine milk IgE-binding epitopes [α-lactalbumin (ALA), β- and κ-casein] and the corresponding, highly homologous human milk peptides were labelled with sera from 15 breastfed infants with CMA, aged 3 weeks to 12 months, and peptide (epitope)-specific IgE antibodies were assessed. Nine of the 15 breastfed infants became asymptomatic during strict maternal avoidance of milk and other major food allergens; six infants remained symptomatic until weaned. Ten older children, aged 5-15 years, with CMA were also assessed. The functional capacity of specific IgE antibodies was assessed by measuring β-hexosaminidase release from rat basophilic leukaemia cells passively sensitized and stimulated with human and bovine ALA. A minimum of one human milk peptide was recognized by IgE antibodies from 9 of 15 (60%) milk-allergic infants, and the majority of older children with CMA. Genuine sensitization to human milk peptides in the absence of IgE to bovine milk was occasionally seen. There was a trend towards specific IgE being detected to more human milk peptides in those infants who did not respond to the maternal milk elimination diet than in those who did (P = 0.099). Functional IgE antibody to human ALA was only detected in infants not responding to the maternal diet. Endogenous human milk epitopes are recognized by specific IgE from the majority of infants and children with CMA. Such autoreactive, human milk-specific IgE antibodies appear to have functional properties in vitro. Their role in provoking allergic symptoms in infants exclusively breastfed by mothers strictly avoiding dietary milk remains unclear. © 2011 Blackwell

    Specific IgE (sIgE) antibody detection using the Siemens IMMULITE ® 3gAllergy™ (3gAllergy) assay have not been sufficiently examined for the diagnosis of food allergy. The aim of this study was to evaluate the utility of measuring sIgE levels using the 3gAllergy assay to diagnose allergic reactions to egg, milk, and wheat. This retrospective study was conducted on patients with diagnosed or suspected allergies to egg, milk and wheat. Patients were divided into two groups according to their clinical reactivity to these allergens based on oral food challenge outcomes and/or convincing histories of immediate reaction to causative food(s). The sIgE levels were measured using 3gAllergy and ImmunoCAP. Predicted probability curves were estimated using logistic regression analysis. We analyzed 1561 patients, ages 0-19 y (egg = 436, milk = 499, wheat = 626). The sIgE levels determined using 3gAllergy correlated with those of ImmunoCAP, classifying 355 patients as symptomatic: egg = 149, milk = 123, wheat = 83. 3gAllergy sIgE levels were significantly higher in symptomatic than in asymptomatic patients (P allergies. However, these probability curves should not be applied interchangeably between different assays. Copyright © 2016 Japanese Society of Allergology. Production and hosting by Elsevier B.V.

    Full Text Available The prevalence of alimentary allergy in children of the 1st year of life is increasing overall. This kind of disorders involves different organs and tissues, and its clinical manifestations are not pathognomic. Among the most important allergens one of the key roles play cow milk proteins. Hypoallergenic formulas are recommended for the non-invasive dietary diagnostics and treatment. Amino-acid-based formulas meet the criteria of being hypoallergenic.

    Full Text Available Abstract Background Cow's milk allergy (CMA is one of the most prevalent human food-borne allergies, particularly in infants and young children from developed countries. Our study aims to evaluate the effects of Lactobacillus rhamnosus GG (LGG administration on CMA development using whole cow's milk proteins (CMP sensitized Balb/C mice by two different sensitization methods. Methods LGG supplemented mice were either sensitized orally with CMP and cholera toxin B-subunit (CTB as adjuvant, or intraperitoneally (IP with CMP but without the adjuvant. Mice were then orally challenged with CMP and allergic responses were accessed by monitoring hypersensitivity scores, measuring the levels of CMP-specific immunoglobulins (IgG1, IgG2a and IgG and total IgE from sera, and cytokines (IL-4 and IFN-γ from spleen lysates. Results Sensitization to CMP was successful only in IP sensitized mice, but not in orally sensitized mice with CMP and CTB. Interestingly, LGG supplementation appeared to have reduced cow's milk allergy (CMA in the IP group of mice, as indicated by lowered allergic responses. Conclusions Adjuvant-free IP sensitization with CMP was successful in inducing CMA in the Balb/C mice model. LGG supplementation favourably modulated immune reactions by shifting Th2-dominated trends toward Th1-dominated responses in CMP sensitized mice. Our results also suggest that oral sensitization by the co-administration of CMP and CTB, as adjuvant, might not be appropriate to induce CMA in mice.

    2015-02-01

    This review summarizes current evidence and recommendations regarding cow's milk allergy (CMA), the most common food allergy in young children, for the primary and secondary care providers. The diagnostic approach includes performing a medical history, physical examination, diagnostic elimination diets, skin prick tests, specific IgE measurements, and oral food challenges. Strict avoidance of the offending allergen is the only therapeutic option. Oral immunotherapy is being studied, but it is not yet recommended for routine clinical practice. For primary prevention of allergy, exclusive breastfeeding for at least 4 months and up to 6 months is desirable. Infants with a documented hereditary risk of allergy (i.e., an affected parent and/or sibling) who cannot be breastfed exclusively should receive a formula with confirmed reduced allergenicity, i.e., a partially or extensively hydrolyzed formula, as a means of preventing allergic reactions, primarily atopic dermatitis. Avoidance or delayed introduction of solid foods beyond 4-6 months for allergy prevention is not recommended. For all of those involved in taking care of children's health, it is important to understand the multifaceted aspects of CMA, such as its epidemiology, presentation, diagnosis, and dietary management, as well as its primary prevention.

    A cohort of 1749 newborns from the municipality of Odense born during 1985 in the University Hospital of Odense were followed prospectively for the development of cow's milk allergy (CMA)/cow's milk protein intolerance (CMI) during their first year. The diagnosis of CMA/CMI was based on elimination....../open milk challenge procedures according to generally accepted criteria. Thirty nine infants (2.2%) developed CMA/CMI. Infants with CMA/CMI were fed cow's milk formula daily during the first month of life significantly more often than infants in the study population (p less than .001). All 39 infants...... with CMA/CMI had ingested cow's milk formula (40-830 mL) neonatally, whereas none of the 210 neonates without supplements of cow's milk formula developed CMA/CMI (p less than .05).

    In our recent clinical trial, the addition of omalizumab to oral immunotherapy (OIT) for milk allergy improved safety, but no significant clinical benefit was detected. We sought to investigate mechanisms by which omalizumab modulates immunity in the context of OIT and to identify baseline biomarkers that predict subgroups of patients most likely to benefit from omalizumab. Blood was obtained at baseline and multiple time points during a placebo-controlled trial of OIT for milk allergy in which subjects were randomized to receive omalizumab or placebo. Immunologic outcomes included measurement of basophil CD63 expression and histamine release and casein-specific CD4 + regulatory T-cell proliferation. Biomarkers were analyzed in relationship to measurements of safety and efficacy. Milk-induced basophil CD63 expression was transiently reduced in whole blood samples from both omalizumab- and placebo-treated subjects. However, IgE-dependent histamine release increased in washed cell preparations from omalizumab- but not placebo-treated subjects. No increase in regulatory T-cell frequency was evident in either group. Subjects with lower rates of adverse reactions, regardless of arm, experienced better clinical outcomes. Pre-OIT basophil reactivity positively associated with occurrence of symptoms during OIT, whereas the baseline milk IgE/total IgE ratio correlated with the likelihood of achieving sustained unresponsiveness. A combination of baseline basophil and serologic biomarkers defined a subset of patients in which adjunctive therapy with omalizumab was associated with attainment of sustained unresponsiveness and a reduction in adverse reactions. Combining omalizumab therapy with milk OIT led to distinct alterations in basophil reactivity but not T-cell responses. Baseline biomarkers can identify subjects most likely to benefit from adjunctive therapy with omalizumab. Copyright © 2017 American Academy of Allergy, Asthma & Immunology. All rights reserved.

    Since the 1930's the scientific literature on cow's milk protein allergy (CMPA) has accumulated. Over the last decade new diagnostic tools and treatment approaches have been developed. The diagnosis of reproducible adverse reactions to cow's milk proteins (CMP), i.e. CMPA, still has to be confirmed by controlled elimination and challenge procedures. Advanced diagnostic testing using epitope and microarray technology may in the future improve the diagnostic accuracy of CMPA by determination of specific IgE against specific allergen components of cow's milk protein. The incidence of CMPA in early childhood is approximately 2-3% in developed countries. Symptoms suggestive of CMPA may be encountered in 5-15% of infants emphasizing the importance of controlled elimination/milk challenge procedures. Reproducible clinical reactions to CMP in human milk have been reported in 0.5% of breastfed infants. Most infants with CMPA develop symptoms before 1 month of age, often within 1 week after inter introduction of CMP-based formula. The majority has two or more symptoms from two or more organ systems. Approximately 50-70% have cutaneous symptoms, 50-60% gastrointestinal symptoms and 20-30% respiratory symptoms. Symptoms may occur within 1 hour after milk intake (immediate reactions) or after 1 hour (late reactions). The prognosis of CMPA is good with a remission rate of approximately 45 to 50% at 1 year, 60 to 75% at 2 years and 85 to 90% at 3 years. Associated adverse reactions to other foods develop in up to 50% and allergy against inhalants in 50 to 80%. The basic treatment of CMPA is avoidance of CMP. In early childhood a milk substitute is needed. Documented extensively hydrolysed formulas are recommended, whereas partially hydrolysed formulas should not be used because of a high degree of antigenicity and allergenicity associated with adverse reactions. In case of intolerance to extensively hydrolysed formulas and multiple food allergies a formula based on aminoacids is

He reported the ingestion of a blend of hydrolyzed whey and casein proteins for bodybuilding for the last 2 years. The in vivo tests showed positivity to CM, α-lactalbumin, β-lactoglobulin and casein extracts, and also to the protein supplement. The serum specific IgE was positive for CM, β-lactoglobulin and α-lactalbumin. The in vivo and in vitro tests results suggested an IgE-mediated CMA. Adult-onset CMA has been rarely reported, and to our knowledge this is the first case possibly related to bodybuilding supplements. The authors theorize that the presentation of large amounts of proteins in the gastrointestinal tract may favor sensitization.

    Whether breast milk (BM) can protect against allergy has been studied extensively, with conflicting results. Variations in mothers' BM composition may explain some of the conflicting results. Our aim was to assess the impact of maternal allergy and probiotic intervention on BM food antibodies, transforming growth factor (TGF)-β(2) and interleukin (IL)-10 and their impact on allergy development in children until the ages of 2 and 5. We measured total IgA, IgA antibodies to cow's milk (CM), casein, β-lactoglobulin and ovalbumin (OVA), TGF-β(2) and IL-10 in 364 colostrum samples and 321 BM samples taken at 3 months from mothers participating in a prospective study evaluating the allergy-preventive effect of probiotics in a cohort with an increased risk for allergy. CM, casein and OVA antibodies, TGF-β(2) and IL-10 were detectable in most samples. Maternal allergy was associated with raised levels of IgA to casein (p = 0.04) and lower levels of TGF-β(2) (p = 0.006) in mature BM. Probiotic supplementation was associated with increased IL-10 (p = 0.046) and decreased casein IgA antibodies (p = 0.027) in mature BM. High OVA IgA antibodies in colostrum were associated with the development of atopy by the age of 2, while low levels in mature BM were a significant risk factor for the development of eczema by the age of 2. TGF-β(2) levels in BM constituted a risk for development of allergy by the age of 2. The immunologic composition of BM was only slightly affected by maternal atopy and could be altered by probiotic supplementation. Small effects of BM components on allergy development in children were evident. Copyright © 2012 S. Karger AG, Basel.

    Full Text Available Folate cycle gene polymorphisms and the levels of endogenous antimicrobial peptides and proteins in the blood and coprofiltrates were studied in 45 children aged 3 to 12 months with cow’s milk protein allergy. The polymorphic variants of the MTHFR, MTRR, and MTR genes were shown to be considered as a risk factor for the development of allergy. There was a significant increase in the levels of zonulin, β-defensin 2, transthyretin, and eosinophil cationic protein in the coprofiltrates and in those of eotaxin, fatty acidbinding proteins, and membrane permeability-increasing protein in the serum (p<0.05. The finding can improve the diagnosis of the disease for a predictive purpose for the evaluation of the efficiency of performed therapy.

    The prebiotic nature of human milk oligosaccharides (HMOs) and increasing evidence of direct immunomodulatory effects of these sugars suggest that they may have some therapeutic potential in allergy. Here, we assess the effect of two HMOs, 2'-fucosyllactose and 6'-sialyllactose, on symptomatology and immune responses in an ovalbumin-sensitized mouse model of food allergy. The effects of oral treatment with 2'-fucosyllactose and 6'-sialyllactose on anaphylactic symptoms induced by oral ovalbumin (OVA) challenge in sensitized mice were investigated. Mast cell functions in response to oral HMO treatment were also measured in the passive cutaneous anaphylaxis model, and direct effects on IgE-mediated degranulation of mast cells were assessed. Daily oral treatment with 2'-fucosyllactose or 6'-sialyllactose attenuated food allergy symptoms including diarrhea and hypothermia. Treatment with HMOs also suppressed antigen-induced increases in mouse mast cell protease-1 in serum and mast cell numbers in the intestine. These effects were associated with increases in the CD4(+) CD25(+) IL-10(+) cell populations in the Peyer's patches and mesenteric lymph nodes, while 6'-sialyllactose also induced increased IL-10 and decreased TNF production in antigen-stimulated splenocytes. Both 2'-fucosyllactose and 6'-sialyllactose reduced the passive cutaneous anaphylaxis response, but only 6'-sialyllactose directly inhibited mast cell degranulation in vitro, at high concentrations. Our results suggest that 2'-fucosyllactose and 6'-sialyllactose reduce the symptoms of food allergy through induction of IL-10(+) T regulatory cells and indirect stabilization of mast cells. Thus, human milk oligosaccharides may have therapeutic potential in allergic disease. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background In 2010, the diagnosis and treatment of IgE-mediated CMA were systematized in a GRADE guideline. Objectives & methods After 6 years, the state of the knowledge in diagnosis and treatment of CMA has largely evolved. We summarize here the main advances, and exemplify indicating some specific points: studies aimed at better knowledge of the effects of breastfeeding and the production of new special formulae intended for the treatment of CMA. The literature (PubMed/MEDLINE was searched using the following algorithms: (1 [milk allergy] AND diagnosis; (2 [milk allergy] AND [formul*] OR [breast*], setting the search engine [6-years] time and [human] limits. The authors drew on their collective clinical experience to restrict retrieved studies to those of relevance to a pediatric allergy practice. Results Several clinical studies did address the possibility to diagnose CMA using new tools in vitro and in vivo, or to diagnose it without any evaluation of sensitization. Some studies also addressed the clinical role of formulae based on milk hydrolysates, soy, or rice hydrolysates in the treatment of CMA. Many studies have elucidated the effects of selective nutrients in breastfed infants on their immunologic and neurologic characteristics. Conclusions Evidence-based diagnostic criteria should be identified for non-IgE-mediated CMA. Debate is ongoing about the best substitute for infants with CMA. In particular, Hydrolyzed Rice Formulae have been widely assessed in the last six years. In the substitute choice, clinicians should be aware of recent studies that can modify the interpretation of the current recommendations. New systematic reviews and metanalyses are needed to confirm or modify the current DRACMA recommendations.

    Lactose is the main carbohydrate in human and mammalian milk. Lactose requires enzymatic hydrolysis by lactase into D-glucose and D-galactose before it can be absorbed. Term infants express sufficient lactase to digest about one liter of breast milk daily. Physiological lactose malabsorption in infancy confers beneficial prebiotic effects, including the establishment of Bifidobacterium-rich fecal microbiota. In many populations, lactase levels decline after weaning (lactase non-persistence; LNP). LNP affects about 70% of the world's population and is the physiological basis for primary lactose intolerance (LI). Persistence of lactase beyond infancy is linked to several single nucleotide polymorphisms in the lactase gene promoter region on chromosome 2. Primary LI generally does not manifest clinically before 5 years of age. LI in young children is typically caused by underlying gut conditions, such as viral gastroenteritis, giardiasis, cow's milk enteropathy, celiac disease or Crohn's disease. Therefore, LI in childhood is mostly transient and improves with resolution of the underlying pathology. There is ongoing confusion between LI and cow's milk allergy (CMA) which still leads to misdiagnosis and inappropriate dietary management. In addition, perceived LI may cause unnecessary milk restriction and adverse nutritional outcomes. The treatment of LI involves the reduction, but not complete elimination, of lactose-containing foods. By contrast, breastfed infants with suspected CMA should undergo a trial of a strict cow's milk protein-free maternal elimination diet. If the infant is not breastfed, an extensively hydrolyzed or amino acid-based formula and strict cow's milk avoidance are the standard treatment for CMA. The majority of infants with CMA can tolerate lactose, except when an enteropathy with secondary lactase deficiency is present.

    Low dose reactive cow's milk (CM) allergic children are at high risk of persistent CM allergy and a positive oral food challenge (OFC). The present study aimed to evaluate if the results of a very low dose (VL) OFC with these children contributes to better management of CM allergy. We retrospectively reviewed subjects with CM allergy who underwent a VL OFC with 3 mL heated CM and had a previous allergic reaction to management of some low dose reactive CM allergic children to change from complete avoidance to partial intake of CM.

    Our aim was to establish the feeding history, presentation, management and rate of resolution for an Irish cohort of children with cow’s milk protein allergy (CMPA) attending a hospital-based outpatient service. This was a cohort study consisting of two parts: a retrospective chart review and a follow-up questionnaire. Fifty-one infants (male: 61%, n=31) were enrolled. Twenty-one (41%) had IgE-mediated allergy. Twenty-nine (57%) had non-IgE mediated allergy. Twenty-two (49%) had tried ≥3 different formulas prior to diagnosis. Of the children who had reached two years, the overall rate of tolerance was 53% (IgE: 35%, non-IgE: 67%). Mild cases of CMPA can be managed in the community. Potential severe complications include faltering growth and anaphylaxis. CMPA should be managed using a multi-disciplinary approach. Increased awareness of CMPA may speed diagnosis and decrease the use of inappropriate formulas.

    Cow milk allergy (CMA) is the most common food allergy in breastfed infants. The aim of this study is to verify whether certain perinatal factors may influence the development of CMA immunoglobulin E (IgE)+. A retrospective, observational study of case and control groups was carried out. Information was collected of patients with CMA IgE+ from our department during the years 1990-2013. Patients of the same age and sex were recruited for the control group. Information on the following variables was collected: sex, age, pregnancy tolerance, duration of pregnancy, type of delivery, isolated doses of formula feeding in hospital (FFH), duration of breastfeeding, and family history of allergy (defined as ≥1 first-degree family member with allergic disease). Statistical analysis was performed using multivariate logistic regression techniques. A total of 211 cases were included in this study. Multivariate analysis showed an influence of duration of breastfeeding, FFH to be a risk factor (OR 4.94; 95% CI 2.68-9.08), especially in caesarean delivery (OR 11.82; 95% CI 2.64-47.50), and prematurity (OR 0.29; 95% CI 0.09-0.92) to be a protective factor. Perinatal factors play a key role in the development of CMA IgE+, with an influence of breastfeeding duration, FFH and caesarean delivery as risk factors and prematurity as a protective factor. While family history had no important role, environmental factors were more decisive. © 2017 S. Karger AG, Basel.

    Cow's milk protein allergy (CMPA) affects between 1.9 and 4.9% of infants and young children. This food allergy requires the complete elimination of cow's milk and its derivatives, impacting on nutritional status. The risk of having protein energy malnutrition (PEM) in children with CMPA has been well documented. In 2007, the World Health Organisation published guidelines on the dietary management of PEM, which has impacted on the recommendations and composition on specialist feeds for many chronic diseases, but not on CMPA. The main change in management of the child with PEM is the protein energy ratio and energy requirements. The ideal protein energy ratio lies between 8.9 and 11.5%, which would ensure a deposition of about 70% lean and 30% fat mass. In addition, for optimal catch-up growth between 5 and 10 g/kg/day, energy requirements should be between 105 and 126 kcal/kg/day. Although most current hypoallergenic formulas fall well within the recommendation for protein, there is a problem in achieving energy requirements. As a result, modular additions are often made, disturbing the protein energy ratio or feeds are concentrated, which impacts on osmolality. We therefore aimed to review current guidelines on PEM and how these can be applied in the management of the malnourished child with CMPA. © 2012 John Wiley & Sons A/S.

    Cow's milk allergy is the most frequent childhood food allergy. Children older than 5 who have not become tolerant have less probabilities of natural tolerance. Specific oral desensitization methods are being investigated in reference centres. The aims of our study were to assess the efficacy of our guideline of specific oral desensitization to cow's milk in children and to know its suitability for anaphylactic children. Both clinical and specific IgE outcomes were evaluated. Eighty-seven children aged 5 to 16 years with a history of cow's milk allergy were included. Prior to desensitization, skin prick test, specific IgE to cow's milk proteins and a double-blind placebo control food challenge were performed in all. Of the 87 patients, 21 had a negative challenge; they were considered tolerant, and they were told to follow a free diet. Of the positive, 44 were anaphylactic and 22 non-anaphylactic. All of them were included. In non-anaphylactic patients, 6 achieved partial and 16 maximum desensitization after 23.1 weeks. In the anaphylactic group, 7 achieved partial and 35 maximum desensitization after 26.4 weeks. Cow's milk-specific IgE levels and casein-specific IgE levels were significantly lower in the tolerant patients at baseline. One year after desensitization, the medium specific cow's milk levels and casein IgE levels had dropped significantly. Our guideline for specific oral desensitization to cow's milk is efficacious even in patients with anaphylactic reactions to cow's milk and represents a significant life change. Immunological changes in 1 year show a drop in cow's milk protein-specific IgE.

  14. The Impact of Baked Egg and Baked Milk Diets on IgE- and Non-IgE-Mediated Allergy.

    Baked milk (BM) and baked egg (BE) diets are increasingly used in the management of milk and egg allergy, rather than avoidance. Children with tolerance versus reactivity to BM and BE may have smaller skin prick test and lower specific IgE, and BM-tolerant children have less basophil reactivity and more peripheral T regulatory cells. However, most milk- and egg-allergic children tolerate BM and BE and an individual's reactivity is unpredictable. Non-reactivity is due to conformational changes in the allergens. Significant differences in the published advice about methods of introduction exist from graded introduction at home to a medically supervised full dose. These approaches carry different risks and may have different immunological effects. Reactivity to BM is a predictor of a severe milk allergy. Therefore, medical supervision for BM and BE introduction is prudent. The baked diet allows dietary liberation. Most, but not all, BM- and BE-tolerant children continue eating the baked foods. The prognosis of children who can eat BM and BE is favorable with likely resolution of their allergy over the next few years. Murine models of BE diets demonstrate that heated egg can impart clinical protection against anaphylaxis and cause immune changes. Most observational human studies of BM and BE diets demonstrate clinical resolution of allergy and favorable immune changes versus regular care controls. However, the one randomized controlled trial for the BE diet in BE-tolerant children did not support an immune-modifying effect of the BE diet. Another study of BE immunotherapy is expected to be completed in 2018. There is currently no evidence for prevention of allergy with the baked diets. There may be a future role for BM and BE in liberating the diets of individuals with non-IgE-mediated allergy given recent studies that a subset of these patients can consume BM without a clinical reaction.

    Introduction: The prevention and management of cow milk allergy (CMA) is still debated. Since CMA is much less frequent in breastfed infants, breastfeeding should be stimulated. Method: Literature was searched using databases to find original papers and reviews on this topic. Results: Hydrolysates with a clinical proof of efficacy are recommended in the prevention and treatment of CMA. However, not all meta-analyses conclude that hydrolysates do prevent CMA or other atopic manifestations such as atopic dermatitis. There are pros and cons to consider partially hydrolysed protein as an option for starter infant formula for each non-exclusively breastfed infant. A challenge test is still recommended as the most specific and sensitive diagnostic test, although a positive challenge test does not proof that the immune system is involved. The Cow Milk Symptom Score (CoMiSS™) is an awareness tool that enables healthcare professionals to better recognize symptoms related to the ingestion of cow milk, but it still needs validation as diagnostic tool. The current recommended elimination diet is a cow milk based extensive hydrolysate, although rice hydrolysates or soy infant formula can be considered in some cases. About 10 to 15% of infants allergic to cow milk will also react to soy. Mainly because of the higher cost, amino acid based formula is reserved for severe cases. There is no place for infant formula with intact protein from other animals as cross-over allergenicity is high. During recent years, attention focused also on the bifidogenic effect of prebiotics and more recently also on human milk oligosaccharides. A bifidogenic gastrointestinal microbiome may decrease the risk to develop allergic disease. The addition of probiotics and prebiotics to the elimination diet in treatment may enhance the development of tolerance development. Conclusion: Breastfeeding is the best way to feed infants. Cow milk based extensive hydrolysates remain the first option for the

    The prevalence of cow's milk protein allergy (CMPA) has increased in recent years, and is associated with antimicrobial use during the perinatal period, prematurity, the type of childbirth, and the decrease in breastfeeding. The aim of this study was to analyze whether there is any association between these factors and the development of CMPA. A retrospective, comparative, cross-sectional, observational study was conducted by reviewing the case records of 101 children diagnosed with CMPA and seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría within the time frame of January 2012 and August 2013. The following variables were included: age, sex, weeks of gestation, history of maternal infection and antimicrobial use during the pregnancy, type of delivery, and feeding with human milk, and its duration. Likewise, the case records of 90 children were reviewed as a control group on not having CMPA or any other allergy. The chi-square test was used for proportions, and the Mann-Whitney U test was used for comparing means in the statistical analysis. The factors associated with CMPA were the use of antimicrobials during gestation and breastfeeding duration in months. Both factors were statistically significant (P<.001). No association was found between CMPA and gestational age or type of delivery. The statistically significant associated factors were breastfeeding duration and the use of antimicrobials during the gestational stage. These results underline the necessity for prospective studies.

    In Italy, rigorous studies obtained with specific and validated questionnaires that explore the impact of exclusion diets on health-related quality of life (HRQoL) in children with food allergies are lacking. In this cross-sectional study, we wished to validate the Italian version of a disease-specific quality of life questionnaire, and assess the impact of exclusion diets on the HRQoL in a cohort of Italian children with IgE-mediated food allergies. Children on an exclusion diet for ≥1 food were enrolled consecutively, and their parents completed the validated Italian version of the Food Allergy Quality of Life Questionnaire-Parent Form (FAQLQ-PF) and Food Allergy Independent Measure (FAIM). Ninety-six parents of children aged 0-12 years answered the FAQLQ-PF. The validity of the construct of the questionnaire was assessed by correlation between the FAQLQ-PF and FAIM-PF (r = 0.85). The Italian version of the FAQLQ had good internal consistency (Cronbach's α >0.70). Factors that mainly influenced the HRQoL were older age, severity of food allergy, and the duration of the cow milk-exclusion diet. The FAQLQ-PF, validated in Italian, is a reliable instrument. Worse QoL scores were observed among older children, those with severe systemic reactions, and those with a prolonged cow milk-free diet. It is very important to consider the QoL assessment as an integral part of food-allergy management. These results emphasize the need to administer exclusion diets only for the necessary time and the importance of assessment of the HRQoL in these patients.

    The patient was a 6-year-old female with milk allergy and persistent asthma. She experienced anaphylactic reactions just after the inhalation of Inavir (Laninamivir Octanoate Hydrate) to treat flu infection. A skin-prick test showed positive reactions for Inavir inhaler powder and lactose used as an excipient but negative for Laninamivir. Same results were obtained in a drug-stimulated basophil activation test. The lactose excipient in Inavir inhaler powder was supposed to contain milk proteins, which caused anaphylactic reactions. To test this possibility, we examined the contamination of allergic milk proteins in the lactose excipient and found the smear band by silver staining, which was identified as β-lactoglobulin (β-LG) by Western blotting using specific monoclonal antibody and patient's sera. The β-LG in Inavir was supposed to be glycosylated with lactose because the molecular weight was slightly higher than β-LG standard reference as seen in mobility. In fact, the incubation with lactose in vitro tended to increase molecular weight. Following these results, we herein report that the trace amounts of β-LG contaminated in the lactose excipient of Inavir could cause immediate allergic reactions. The risk that the lactose-containing dry powder inhalers cause allergic reactions for patients with cow's milk allergy need to be reminded. In particular, the use for flu patients should be paid careful attention because of increased airway hypersensitivity in those patients.

    Full Text Available Background: The cow’s milk protein allergy is the most common food allergy among children under two years and is associated with other atopic diseases. Objective: To evaluate cow’s milk protein allergy frequency in patients sensitized to them, attended at the consultation of Immunology and Allergy in the Hospital Infantil de México Federico Gómez, and its association with other atopic diseases. Material and method: A cross-sectional, analytical and descriptive study that reviewed medical records of patients aged 0-19 years, attended at the consultation of Immunology and Allergy in the Hospital Infantil de México Federico Gómez, from January 2010 to January 2013, sensitized to the cow’s milk protein by in vitro or in vivo studies, mediated or not by IgE, to determine its association with other atopic diseases during the course of their clinical evolution. Results: We included 252 patients with symptoms suggestive of cow’s milk protein allergy, which was diagnosed only in 15.1% by oral challenge. In relation to respiratory symptoms, about two-thirds of patients had rhinorrhea, nasal obstruction and nasal itching. Regarding gastrointestinal symptoms, about a third had abdominal pain, diarrhea and abdominal distension, being statistically significant. The most common dermatologic symptom, statistically significant, was xerosis. The most frequently associated atopic diseases were food allergy (76.3%, allergic rhinitis (65.8%, asthma (47.4% and atopic dermatitis (23%. Conclusions: The cow’s milk protein allergy can be associated with other atopic diseases, such as allergy to other foods, allergic rhinitis, asthma and atopic dermatitis.

    ultrasound (US) has been an important diagnostic tool to identify several causes of gastrointestinal bleeding. Infants with cow's milk allergy (CMA) may present hematochezia and the confirmation of the diagnosis can be difficult. The aim of this study is to describe grayscale and color Doppler ultrasound findings in patients with CMA. we retrospectively studied 13 infants with CMA. All infants presented severe hematochezia and abdominal pain. All underwent an US study with the diagnosis of allergic colitis. This diagnosis was based on clinical findings, recovery after infant or mother exclusion diets in the case of exclusive breastfeeding and positive oral challenge test. the mean age ranged from 1 to 6 months (mean=3.53). Seven out of 13 infants (53.8%) had grayscale and color Doppler sonographic repeated after exclusion diet. Twelve out of 13 (92,3%) showed abnormalities at US and CDUS at beginning. The positive findings suggesting colitis were thickened bowel walls and increased vascularity, especially in the descending and sigmoid colon. Colonoscopy and histopathological findings were compatible with allergic colitis. After a diet change the 13 infants recovered and their oral challenge tests were positive. Doppler US may be very useful in diagnosing secondary colitis, such as CMA, and to exclude several other abdominal diseases that can emulate this disease.

    Full Text Available Introduction : To find out whether children with food allergy have an increased risk of recurrent upper and lower respiratory tract infections and of asthma. Aim: To describe the clinical profile of children diagnosed with food allergy referred to the Allergy Clinic. Material and methods : We conducted a retrospective study to assess the patients’ demographic, anthropometric and clinical data. The analysis included data of all children by the age of 10 years (registered with the Allergy Clinic between 2012 and 2013 in whom IgE mediated food allergy had been diagnosed during 18 months of observation. Results : We included 280 children into the analysis. Recurrent respiratory tract infections (rRTI, asthma and gastrointestinal (GI symptoms were observed in 153 (54.6%, 96 (34.3%, 39 (13.9%, respectively, with a significant increasing trend across age-subgroups. In children from 1 to 2 years old, sensitization to -lactoglobulin increased the risk of rRTI (OR = 3.91; 95% CI: 1.03–14.87. In older children sensitization to allergens other than milk or egg decreases the risk of rRTI (OR = 0.25; 95% CI: 0.10–0.62; sensitization to egg decreased the risk of asthma diagnosis (OR = 0.09; 95% CI: 0.01–0.75. We did not identify food allergens which change the risk of GI symptoms in children. This finding was consistent throughout all age-subgroups. Conclusions : Sensitization to -lactoglobulin increased the risk of rRTI in children under 2 years of age nearly four times. The presence of sensitization to food allergens above 3 years of age did not increase the risk of developing clinical presentation of food allergy other than atopic dermatitis.

    The role of maternal avoidance diets in the prevention of food allergies is currently under debate. Little is known regarding the effects of such diets on human milk (HM) composition or induction of infant humoral responses. To assess the association of maternal cow's milk (CM) avoidance during breastfeeding with specific IgA levels in HM and development of cow's milk allergy (CMA) in infants. We utilized HM and infant serum samples from a prospective birth cohort of 145 dyads. Maternal serum and HM samples were assessed for casein and beta-lactoglobulin (BLG)-specific IgA and IgG by ELISA; 21 mothers prophylactically initiated a strict maternal CM avoidance diet due to a sibling's history of food allergy and 16 due to atopic eczema or regurgitation/vomiting seen in their infants within the first 3 months of life. Infants' sera were assessed for casein and BLG-specific IgG, IgA and IgE; CMA was confirmed by an oral food challenge. The impact of HM on BLG uptake was assessed in transcytosis assays utilizing Caco-2 intestinal epithelial cell line. Mothers avoiding CM had lower casein- and BLG-specific IgA in HM than mothers with no CM restriction (P = 0.019 and P = 0.047). Their infants had lower serum casein- and BLG-specific IgG(1) (P = 0.025 and P < 0.001) and BLG-specific IgG(4) levels (P = 0.037), and their casein- and BLG-specific IgA levels were less often detectable than those with no CM elimination diet (P = 0.003 and P = 0.007). Lower CM-specific IgG4 and IgA levels in turn were associated with infant CMA. Transcytosis of BLG was impaired by HM with high, but not low levels of specific IgA. Maternal CM avoidance was associated with lower levels of mucosal-specific IgA levels and the development of CMA in infants. HM IgA may play a role in preventing excessive, uncontrolled food antigen uptake in the gut lumen and thereby in the prevention of CMA. © 2013 John Wiley & Sons Ltd.

    Cow's milk protein allergy (CMPA) is highly prevalent in infants (2-5%). It has a wide clinical spectrum, and confirmation through an oral food challenge (OFC) is relevant for its differential diagnosis. Information on this topic is scarce in Chile. To describe the demographic and clinical features of infants with suspected CMPA. A retrospective study of patients<1 year-old, treated for suspected CMPA between 2009 and 2011. Demographic data, symptoms of atopy, nutrition at the time of diagnosis, CMPA symptoms, diagnostic studies, and response to treatment were recorded. Diet response at least 4 weeks after milk modification, and clinical behavior when suspected foods were added back to the diet were considered standard diagnostic criteria. Descriptive statistics were performed using Epiinfo ™ software. The study included 106 infants, of whom, 51% male, 80% term newborns, 74% with≥1 atopic parent, and 34% with ≥1 parent/sibling with food allergy. The median age at onset of symptoms was 1.5 months (range 1.5-2m). Almost half (46%) were breast-feeding≥6m, with 15% receiving formula milk since the neonatal period, and 49% before the third month. Common symptoms were: vomiting (63%), colic (49%), and bleeding on passing stools (41%). No anaphylaxis was identified, and 61% had≥2 symptoms at debut. Only 34% were subjected to OFC. The most frequently requested tests were, test patch (43%), prick test (40%), and blood in stools (37%). 43% breast feeding with exclusion diet, 24% extensively hydrolysed formula, 26% amino acid formula, and 7% others. Demographic characteristics and risk factors were similar to those previously described in international literature. Clinical presentation was early in life, and digestive symptoms predominated. OFC was underused for diagnosis, and most of the tests requested did not change management. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

    AIMS: The primary aim was to assess whether there were differences in symptoms, laboratory data, and oesophageal pH-metry between infants with primary gastro-oesophageal reflux and those with reflux secondary to cows' milk protein allergy (CMPA). PATIENTS AND METHODS: 96 infants (mean(SD) age 7.8(2.0) months) with either primary gastro-oesophageal reflux, reflux with CMPA, CMPA only, or none of these (controls) were studied. Symptoms, immunochemical data, and oesophageal pH were compared between the four groups and the effect of a cows' milk protein-free diet on the severity of symptoms was also assessed. RESULTS: 14 out of 47(30%) infants with gastro-oesophageal reflux had CMPA. These infants had similar symptoms to those with primary gastro-oesophageal reflux but higher concentrations of total IgE and circulating eosinophils (p gastro-oesophageal reflux secondary to CMPA and in 24 of 25 infants with CMPA only. No infants with primary gastro-oesophageal reflux and none of the controls had this pattern. A cows' milk protein-free diet was associated with a significant improvement in symptoms only in infants with gastro-oesophageal reflux with CMPA. CONCLUSION: A characteristic oesophageal pH pattern is useful in distinguishing infants with gastro-oesophageal reflux associated with CMPA. PMID:8813871

    Full Text Available Dietotherapy along with medicinal and external treatment is one of components of complex treatment of atopic dermatitis (AD in children. Severe forms of alimentary allergy are treated with special formulas based on casein hydrolisates. Clinical effectiveness of such formula was studied in 20 patients 2–7 months old intolerant to proteins of cow’s and goat’s milk. Treatment resulted in remission achievement, lessening of external therapy and cancellation of medicinal one in all children including those with cutaneous and gastrointestinal symptoms of AD.Key words: children, atopic dermatitis, dietotherapy, casein hydrolysate, SCORAD.(Voprosy sovremennoi pediatrii — Current Pediatrics. – 2010;9(3:97-101

    The aim of the study was to assess the use of faecal calprotectin (FCP) in infants with signs and symptoms of non-IgE-mediated cow's milk protein allergy (CMA) for both diagnosis and prediction of clinical response at the time of withdrawal of milk proteins. A one year prospective study was conducted on 82 infants between 1 and 12 months of age in the Eastern area of Málaga-Axarquía, of whom 40 of them had been diagnosed with non-IgE-mediated CMA (with suggestive symptoms and positive response to milk withdrawal), 12 not diagnosed with CMA, and 30 of them were the control group. FCP was measured at three different times: time of diagnosis, and one and three months later. ANOVA for repeated measures, nominal logistic regression and ROC curves were prepared using the SPSS.20 package and Medcalc. Differences between diagnostic and control groups were assessed: there was a statistically significant relationship (p<.0001) between high FCP levels and infants suffering CMA, as well as the levels at time of diagnosis, 1 and 3 months (p <.001). A ROC curve was constructed between FCP levels and diagnosis of CMA, with 138 ug/g, with the best cut-off being with an area under the curve of 0.89. However, it is only 0.68 to predict a clinical response. FCP levels lower than 138ug/g could be useful to rule out non-IgE-mediated CMA diagnosis. Calprotectin is not a good test to predict clinical response to milk withdrawal. Copyright © 2015 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

    Cow's milk allergy (CMA) is the most common food allergy among infants. No data are available on the health care burden of suspected CMA in general practice. This study was conducted to evaluate the burden of suspected CMA in general practice (GP): (a) prevalence, (b) presenting symptoms, (c) diagnostic process, (d) guideline adherence, and (e) dietary measures. A retrospective cohort study was carried out in four Julius Healthcare Centers (JHCs). These JHCs form the core primary care academic network of the department of general practice of the University Medical Center of Utrecht. Electronic records of the first year of infants born May 2009 - April 2010 registered in the JHCs were screened for possible CMA suspicion. Preventive child healthcare (PCH) records were reviewed for additional information. Clinical presentation, diagnostic strategies and dietary measures were extracted. Of 804 infants evaluated, 55 presented with symptoms fitting the suspicion of CMA (prevalence of 7%). Presenting complaints involved the skin (71%); the gastrointestinal tract (60%); the respiratory tract (13%) or other symptoms (36%) and 23 infants presented with symptoms of two or more organ systems. In 31 children (56%) a food challenge was performed (n = 28 open and n = 3 double-blind). Open challenge test results were difficult to interpret due to inadequate implementation or reporting. None had confirmed CMA after an adequate challenge test. Long term milk substitute formulas were prescribed in 39 (71%) infants. On a yearly basis seven percent of children visit their GP for suspected CMA. A positive CMA diagnosis was rarely established after adequate implementation and reporting of diagnostics, yet long term dietary measures were prescribed in >70% of patients. There is definitely need for improvement of diagnosing CMA in primary care.

    Food allergy is a major public health problem for which there is no effective treatment. We examined the immunological changes that occurred in a group of children with significant cow’s milk allergy undergoing a novel and rapid high dose oral desensitization protocol enabled by treatment with omalizumab (anti-IgE mAb). Within a week of treatment, the CD4+ T cell response to milk was nearly eliminated, suggesting anergy in, or deletion of, milk-specific CD4+ T cells. Over the following three months while the subjects remained on high doses of daily oral milk, the CD4+ T cell response returned, characterized by a shift from IL-4 to IFN-γ production. Desensitization was also associated with reduction in milk-specific IgE and a 15-fold increase in milk-specific IgG4. These studies suggest that high dose oral allergen desensitization may be associated with deletion of allergen-specific T cells, without the apparent development of allergen-specific Foxp3+ regulatory T cells.

    The aim of this systematic review was to evaluate the efficacy of amino acid-based formulas (AAF) in patients with cow's milk allergy (CMA). Studies were identified using electronic databases and bibliography searches. Subjects eligible for inclusion were patients of any age with CMA or symptoms suggestive of it. Comparisons of interest were AAF vs. extensively hydrolysed formula (eHF), AAF vs. soy-based formula (SF) and AAF vs. cow's milk or cow's milk-based formula. Outcomes of interest were gastrointestinal (GI), dermatological, respiratory and behavioural symptoms as well as growth. A total of 20 studies [three head-to-head randomized controlled trials (RCTs), three cross-over challenge RCTs, seven clinical trials (CTs) and seven case reports (CRs)] were included in the review. In infants with confirmed or suspected CMA, the use of an AAF was shown to be safe and efficacious. Findings from RCT comparisons of AAF with eHF showed that both formulas are equally efficacious at relieving the symptoms of CMA in confirmed or suspected cases. However, infants in specific subgroups (e.g. non-IgE mediated food-induced gastro-enterocolitis-proctitis syndromes with failure to thrive, severe atopic eczema, or with symptoms during exclusive breastfeeding) were more likely overall to benefit from AAF, as intolerance to eHF may occur. In such cases, symptoms persisting despite eHF feeding usually remit on AAF, and catch-up growth may be seen. Meta-analysis of the findings was not possible due to lack of homogenous reporting of outcomes in the original trials. This systematic review shows clinical benefit from use of AAF in both symptoms and growth in infants and children with CMA who fail to tolerate eHF. Further studies are required to determine the relative medical or economic value of initial treatment with AAF in infants at high risk of eHF intolerance.

    A transglutaminase cross-linked caseinate was designed for use in dairy products to increase the viscosity of food matrices. The difference in structure of cross-linked caseinate might have implications for the risk of developing cow's milk allergy. The sensitizing capacity and the allergenicity (the potency to induce an allergic effector response) of cross-linked sodium caseinate was investigated using a mouse model for cow's milk allergy. Mice were orally sensitized with cross-linked caseinate or caseinate using cholera toxin as adjuvant. Anaphylactic shock reactions, change in body temperature, acute allergic skin response, caseinate-, cross-linked caseinate-IgE and mMCP-1 concentrations were determined after challenge with cross-linked caseinate or caseinate. Sensitization with cross-linked caseinate did not result in anaphylactic shock symptoms, drop in body temperature or release of serum mMCP-1. A tendency toward decreased casein-specific IgE levels was observed. The allergenicity did not differ between both products. These results indicate that in already caseinate-sensitized mice, cross-linked caseinate did not provoke more pronounced allergenic reactions compared to sodium caseinate. On top of that, reduced sensitization to cross-linked caseinate was observed. Cross-linked caseinate might therefore be an interesting new dietary concept for humans at risk for food allergy although more mechanistic studies and clinical trials are needed for validation.

    Full Text Available There are conflicting data to support the practice of delaying the introduction of allergenic foods into the infant diet to prevent allergy development. This study investigated immune response development after early oral egg antigen (Ovalbumin; OVA exposure in a rat pup model. Brown Norway (BN rat pups were randomly allocated into groups: dam reared (DR, DR pups challenged daily (days 4–13 with oral OVA (DR + OVAc, DR pups challenged intermittently (on day 4, 10, 12, and 13 with oral OVA (DR + OVAi, formula-fed pups (FF, and FF pups challenged daily with oral OVA (FF + OVA. Immune parameters assessed included OVA-specific serum IgE, IgG1, and IgA. Ileal and splenic messenger ribonucleic acid (mRNA expression of transforming growth factor-beta (TGF-β1, mothers against decapentaplegic (Smad 2/4/7, and forkhead box P3 (Foxp3 were determined. Ileum was stained for TGF-β1 and Smad4. Results. Feeding OVA daily to DR pups maintained systemic and local gut antibody and immunoregulatory marker mRNA responses. Systemic TGF-β1 was lower in DR + OVAi pups compared to DR and DR + OVAc pups. Feeding OVA to FF pups resulted in significantly greater OVA-specific IgE and IgG1, and lower IgA and TGF-β1 and Smad expression compared to DR pups. Conclusions. Early daily OVA exposure in the presence of maternal milk maintains immune markers associated with a regulated immune response, preventing early allergic sensitization.

    Immunoglobulin E-mediated allergy to cow's milk protein (CMP) tends to subside over years of follow-up. The gold standard for detecting such allergy has been the oral challenge test. The development of some other test for determining the correct timing of the oral challenge test would avoid unnecessary patient discomfort. The aim of this study was to determine whether monitoring cow's milk (CM) specific IgE levels over time can be used as a predictor for determining when patients develop clinical tolerance. A prospective 4-year follow-up study was made of 170 patients with IgE-mediated allergy to CMP, involving periodic evaluations (12, 18, 24, 36 and 48 months) with the determination of casein and CM specific IgE on each visit, along with CM challenge testing. ROC curves were used to analyse the sensitivity, specificity and predictive values of the casein and CM specific IgE levels versus the challenge test outcomes at the different moments of follow-up. In the course of follow-up, 140 infants (82 %) became tolerant. Specific IgE levels to CM: 2.58, 2.5, 2.7, 2.26, 5 kU(A)/l and to casein: 0.97, 1.22, 3, 2.39, 2.73 kU(A)/l, respectively, predicted clinical reactivity (greatest diagnostic efficiency values) at the different analysed moments of follow-up (12, 18, 24, 36 and 48 months). Quantification of CMP specific IgE is a useful test for diagnosing symptomatic allergy to CM in the paediatric population, and could eliminate the need to perform oral challenges tests in a significant number of children.

    Background Cross-reactivity between soybean allergens and bovine caseins has been previously reported. In this study we aimed to map epitopes of the major soybean allergen Gly m 5 that are co-recognized by casein specific antibodies, and to identify a peptide responsible for the cross-reactivity. Methods Cow's milk protein (CMP)-specific antibodies were used in different immunoassays (immunoblotting, ELISA, ELISA inhibition test) to evaluate the in vitro recognition of soybean proteins (SP). Recombinant Gly m 5 (α), a truncated fragment containing the C-terminal domain (α-T) and peptides of α-T were obtained and epitope mapping was performed with an overlapping peptide assay. Bioinformatics tools were used for epitope prediction by sequence alignment, and for modelling the cross-recognized soy proteins and peptides. The binding of SP to a monoclonal antibody was studied by surface Plasmon resonance (SPR). Finally, the in vivo cross-recognition of SP was assessed in a mouse model of milk allergy. Results Both α and α-T reacted with the different CMP-specific antibodies. α-T contains IgG and IgE epitopes in several peptides, particularly in the peptide named PA. Besides, we found similar values of association and dissociation constants between the α-casein specific mAb and the different milk and soy components. The food allergy mouse model showed that SP and PA contain the cross-reactive B and T epitopes, which triggered hypersensitivity reactions and a Th2-mediated response on CMP-sensitized mice. Conclusions Gly m 5 is a cross-reactive soy allergen and the α-T portion of the molecule contains IgG and IgE immunodominant epitopes, confined to PA, a region with enough conformation to be bound by antibodies. These findings contribute to explain the intolerance to SP observed in IgE-mediated CMA patients, primarily not sensitised to SP, as well as it sets the basis to propose a mucosal immunotherapy for milk allergy using this soy peptide.

    Although studies of oral immunotherapy (OIT) for food allergy have shown promise, treatment is frequently complicated by adverse reactions and, even when successful, has limited long-term efficacy because benefits usually diminish when treatment is discontinued. We sought to examine whether the addition of omalizumab to milk OIT reduces treatment-related reactions, improves outcomes, or both. This was a double-blind, placebo-controlled trial with subjects randomized to omalizumab or placebo. Open-label milk OIT was initiated after 4 months of omalizumab/placebo with escalation to maintenance over 22 to 40 weeks, followed by daily maintenance dosing through month 28. At month 28, omalizumab was discontinued, and subjects passing an oral food challenge (OFC) continued OIT for 8 weeks, after which OIT was discontinued with rechallenge at month 32 to assess sustained unresponsiveness (SU). Fifty-seven subjects (7-32 years) were randomized, with no significant baseline differences in age, milk-specific IgE levels, skin test results, or OFC results. At month 28, 24 (88.9%) omalizumab-treated subjects and 20 (71.4%) placebo-treated subjects passed the 10-g "desensitization" OFC (P = .18). At month 32, SU was demonstrated in 48.1% in the omalizumab group and 35.7% in the placebo group (P = .42). Adverse reactions were markedly reduced during OIT escalation in omalizumab-treated subjects for percentages of doses per subject provoking symptoms (2.1% vs 16.1%, P = .0005), dose-related reactions requiring treatment (0.0% vs 3.8%, P = .0008), and doses required to achieve maintenance (198 vs 225, P = .008). In this first randomized, double-blind, placebo-controlled trial of omalizumab in combination with food OIT, we found significant improvements in measurements of safety but not in outcomes of efficacy (desensitization and SU).

    Oral desensitization in children allergic to cow's milk proteins is not risk free. The analysis of factors that may influence the outcome is of utmost importance. To analyze the efficacy and safety of the oral desensitization according to specific IgE (sIgE) level and adverse events during the maintenance phase. Thirty-six patients allergic to cow's milk (mean age, 7 years) were included in an oral desensitization protocol. Patients were grouped according to sIgE levels (ImmunoCAP) into groups 1 (sIgE 17-50 kU/L). Nineteen children were included as a control group. Serum sIgE levels to cow's milk and its proteins were determined at inclusion and 6 and 12 months after finishing the desensitization protocol. Thirty-three of 36 patients were successfully desensitized (200 mL): 100% of group 1 and 88% of groups 2 and 3. Desensitization was achieved in a median of 3 months (range, 1-12 months); 90% of the patients in group 1, 50% of the patients in group 2, and 30% of the patients in group 3 achieved tolerance in less than 3 months (P = .04). In the control group only 1 child tolerated milk in oral food challenge after 1 year. During the induction phase, there were 53 adverse events in 27 patients (75%). Patients of groups 2 and 3 had more severe adverse events compared with group 1. During the maintenance phase, 20 of 33 patients (60%) had an adverse event. Oral desensitization is efficacious. Tolerance is achieved earlier when sIgE is lower. Severe adverse events are frequent, especially in patients with higher sIgE levels.

    Children with cow's milk allergy (CMA) need a cow's milk protein (CMP) free diet to prevent allergic reactions. For this, reliable allergy-information on the label of food products is essential to avoid products containing the allergen. On the other hand, both overzealous labeling and misdiagnosis that result in unnecessary elimination diets, can lead to potentially hazardous health situations. Our objective was to evaluate if excluding CMA by double-blind placebo-controlled food challenge (DBPCFC) prevents unnecessary elimination diets in the long term. Secondly, to determine the minimum eliciting dose (MED) for an acute allergic reaction to CMP in DBPCFC positive children. All children with suspected CMA under our care (Oct'05-Jun'09) were prospectively enrolled in a DBPCFC. Placebo and verum feedings were administered on two randomly assigned separate days. The MED was determined by noting the 'lowest observed adverse effect level' (LOAEL) in DBPCFC-positive children. Based on the outcomes of the DBPCFC a dietary advice was given. Parents were contacted by phone several months later about the diet of their child. 116 children were available for analysis. In 76 children CMA was rejected. In 60 of them CMP was successfully reintroduced, in 2 the parents refused introduction, in another 3 the parents stopped reintroduction. In 9 children CMA symptoms reappeared. In 40 children CMA was confirmed. Infants aged ≤ 12 months in our study group have a higher cumulative distribution of MED than older children. Excluding CMA by DBPCFC successfully stopped unnecessary elimination diets in the long term in most children. The MEDs form potential useful information for offering dietary advice to patients and their caretakers.

Methods: Decision modeling was used to estimate the probability of infants developing tolerance to cow's milk by 18 months, based on an observational study dataset. The model also estimated the cost (at 2012/2013 prices of health care resource use funded by the INHS and formulae paid for by parents over 18 months after starting a formula, as well as the relative cost-effectiveness of each of the formulae. Results: The probability of developing tolerance to cow's milk by 18 months was higher among infants with either IgE-mediated or non-IgE-mediated allergy who were fed eHCF + LGG compared to those fed one of the other formulae. The total health care cost of initially feeding infants with eHCF + LGG was less than that of feeding infants with one of the other formulae. Hence, eHCF + LGG affords the greatest value for money to both the INHS and parents of infants with either IgE-mediated or non-IgE-mediated CMA. Conclusion: Using eHCF + LGG instead of eHCF, SBF, HRF, or an AAF for first-line management of newly diagnosed infants with CMA in Italy affords a cost-effective use of publicly funded resources, and is cost-effective from the parents' perspective, since it improves outcome for less cost.

    Until now, the basic treatment for food allergy has been to avoid the offending item. This approach is difficult in the case of common foods and in the case where there is a risk of severe reaction after consuming the offending food, even inadvertently. This is the follow-up of a previous study aimed at desensitizing 21 children with immunoglobulin E (IgE)-mediated cow's milk (CM) allergy. This protocol was totally or partially successful in 85% of cases, but failed in the remaining 15%. Our aims were to study the long-term effectiveness and safety of oral CM desensitization, and the prognostic value of Skin Prick Test (SPT) and specific serum CM IgE. The 21 children were called back (one dropped out). The allergic history and other information on CM intake over the last 4-5 yr were recorded. Children underwent SPT, and end-point SPT, with casein and alpha-lactoalbumin. Specific CM IgE was also measured. At follow-up, 14/20 children totally (n = 13, 65%) or partially (n = 1, 5%) tolerated CM. None of the recalled children reported use of emergency care. SPT positivity to casein and/or alpha-lactoalbumin decreased significantly (p < 0.01), and all the negative SPT referred to the tolerant children. Cutaneous sensitivity to both casein and alpha-lactoalbumin (end-point SPT) significantly decreased after the 6-month desensitization period of the previous study (p < 0.001), but did not decrease significantly at follow-up. A significant reduction of serum-specific CM IgE was also observed (p < 0.05). Clinical tolerance induced by oral CM desensitization persists in time. Negativization of SPT and reduction of specific CM IgE could be considered prognostic indicators of CM tolerance. Oral CM desensitization seems to be a promising method to treat CM food allergy. This protocol is time-consuming but offers the advantage that it can be performed at home. This methodology must only be used by trained staff.

    Children with Phenylketonuria (PKU) and severe cow's milk protein allergy (CMPA) consume prescribed, specially formulated, foods for special medical purposes (FSMPs) as well as restricted amounts of normal foods. These patients are exposed to artificial sweeteners from the consumption of a combination of free and prescribed foods. Young patients with PKU and CMPA have a higher risk of exceeding acceptable daily intakes (ADI) for additives than age-matched healthy children. A predictive modelling approach has been adapted successfully to assess the additive exposure of young patients with PKU and CMPA to artificial sweeteners. Steviol glycosides (E960) are at various stages of regulatory approval for the various food categories in the EU but are not as yet permitted for use in products intended for young children. The aim of this study was to predict potential steviol glycoside exposure in young children with PKU and CMPA considering the potential for future provisions for the use of this sweetener. The recent introduction of steviol glycosides means that no exposure data are available for children with CMPA and PKU. Food consumption data were derived from the food consumption survey data of healthy young children in Ireland from the National Preschool and Nutrition Survey (NPNS, 2010-11). Specially formulated amino acid-based FSMPs are used to replace whole or milk protein foods and were included in the exposure model to replace restricted foods. The recommendations to ensure adequate protein intake in these patients were used to determine FSMP intake. Exposure assessment results indicated that the maximum permitted level (MPL) for FSMPs would warrant careful consideration to avoid exposures above the ADI. These data can be used to inform recommendations for the medical nutrition industry.

    A diagnosis of food allergy adversely impacts one's ability to join or remain in the military. Inadequate knowledge or misconceptions of current military-specific standards regarding food allergy and how these apply to enlistment, induction, and retention in the United States military can potentially lead to inaccurate counseling as each military service has specific regulations which impact the evaluation and decision-making process. Recognizing this knowledge gap, the American Allergy, Asthma, and Immunology (AAAAI) Military Allergy and Immunology Assembly (MAIA) established a Work Group who reviewed and summarized all aspects of military instructions, policies, and regulations regarding IgE mediated food allergy. A flowchart was developed outlining each step of the military entry process for an individual with a history of food allergy. Further, summary tables were made to provide improved "fluency" regarding each service's medical regulations while key considerations were outlined for the allergist who is evaluating an individual who is seeking military entry or retention. Both civilian and military allergists play an essential role in the evaluation, counseling, and management of patients with a food allergy history. Understanding the service-specific language and regulations regarding food allergy will improve the allergist's awareness, counseling, and management of these individuals. Copyright © 2018.

  14. Cow's milk and goat's milk.

    Science.gov (United States)

    Turck, Dominique

    2013-01-01

    Cow's milk is increasingly suggested to play a role in the development of chronic degenerative, non-communicable disorders whereas goat's milk is advocated as having several health benefits. Cow's milk is a rich and cheap source of protein and calcium, and a valuable food for bone health. Despite their high content in saturated fats, consumption of full-fat dairy products does not seem to cause significant changes in cardiovascular disease risk variables. Early introduction of cow's milk is a strong negative determinant of iron status. Unmodified cow's milk does not meet nutritional requirements of infants although it is acceptable to add small volumes of cow's milk to complementary foods. Cow's milk protein allergy has a prevalence ranging from 2 to 7%, and the age of recovery is usually around 2-3 years. The evidence linking cow's milk intake to a later risk of type 1 diabetes or chronic degenerative, non-communicable disorders (obesity, metabolic syndrome, type 2 diabetes, hypertension) is not convincing. Milk probably protects against colorectal cancer, diets high in calcium are a probable cause of prostate cancer, and there is limited evidence suggesting that high consumption of milk and dairy products increases the risk for prostate cancer. There is no evidence to support the use of a cow's milk-free diet as a primary treatment for individuals with autistic spectrum disorders. Unmodified goat's milk is not suitable for infants because of the high protein and minerals content and of a low folate content. Goat's milk has no clear nutritional advantage over cow's milk and is not less allergenic. The European Food Safety Authority recently stated that proteins from goat's milk can be suitable as a protein source for infant and follow-on formula, provided the final product complies with the compositional criteria laid down in Directive 2006/141/EC.

    Peanut allergy may affect up to 2% of children in some countries, making it one of the most common conditions of childhood. Peanut allergy is a marker of a broad and possibly severe atopic phenotype. Nearly all children with peanut allergy have other allergic conditions. Peanut accounts for a disproportionate number of fatal and near fatal food-related allergies. Families with a child or children with peanut allergy can struggle to adapt to the stringent avoidance measures required. Although oral induction of tolerance represents the cutting edge of peanut allergy management, it is not yet ready for routine practice.

    Peanut nut and tree nut allergy are characterised by IgE mediated reactions to nut proteins. Nut allergy is a global disease. Limited epidemiological data suggest varying prevalence in different geographical areas. Primary nut allergy affects over 2% of children and 0.5% of adults in the UK. Infants with severe eczema and/or egg allergy have a higher risk of peanut allergy. Primary nut allergy presents most commonly in the first five years of life, often after the first known ingestion with typical rapid onset IgE-mediated symptoms. The clinical diagnosis of primary nut allergy can be made by the combination of a typical clinical presentation and evidence of nut specifc IgE shown by a positive skin prick test (SPT) or specific IgE (sIgE) test. Pollen food syndrome is a distinct disorder, usually mild, with oral/pharyngeal symptoms, in the context of hay fever or pollen sensitisation, which can be triggered by nuts. It can usually be distinguish clinically from primary nut allergy. The magnitude of a SPT or sIgE relates to the probability of clinical allergy, but does not relate to clinical severity. SPT of ≥ 8 mm or sIgE ≥ 15 KU/L to peanut is highly predictive of clinical allergy. Cut off values are not available for tree nuts. Test results must be interpreted in the context of the clinical history. Diagnostic food challenges are usually not necessary but may be used to confirm or refute a conflicting history and test result. As nut allergy is likely to be a long-lived disease, nut avoidance advice is the cornerstone of management. Patients should be provided with a comprehensive management plan including avoidance advice, patient specific emergency medication and an emergency treatment plan and training in administration of emergency medication. Regular re-training is required. © 2017 John Wiley & Sons Ltd.

    Full Text Available Food allergy prevalence has increased during the last years, affecting 15-20% of children, in this case, egg allergy affects from 0.5-2.5%. Most of the egg allergic reactions are type I or IgE mediated antibodies against egg proteins. Five major proteins have been identified: ovomucoid (Gal d1, ovoalbumin (Gal d2, ovotransferrin (Gal d3, lysozyme (Gal d4 and albumin (Gal d5. Ovomucoid protein, which is found in the egg white, is heat resistant and enzyme resistant. This protein is the most allergenic and the most common in egg composition. Clinical Revista México 235 Góngora-Meléndez MA y col. Alergia a las proteínas del huevo en edad pediátrica Revista México diagnosis requires a detailed questionnaire. Skin prick test or Ige specific diagnosis are made as first choice. Skin prick tests are quick and useful to determine the presence of IgE specific antibodies to egg. Specific IgE for egg can be measured using standarized IgE studies in vitro, making a quantitative measure. Traditionally with the clinical history a diagnosis can be made. Standarized oral double blinded-placebo controlled challenge continues to be the gold standard for food allergy diagnosis. The identification and elimination of egg proteins from the diet is the primary treatment and the only one validated to this food, but there are more studies needed to stablish protocols for each specific egg allergen before the oral inmunotherapy becomes a routine practice.

    Full Text Available Food allergy is an important public health problem affecting 5% of infants and children in Korea. Food allergy is defined as an immune response triggered by food proteins. Food allergy is highly associated with atopic dermatitis and is one of the most common triggers of potentially fatal anaphylaxis in the community. Sensitization to food allergens can occur in the gastrointestinal tract (class 1 food allergy or as a consequence of cross reactivity to structurally homologous inhalant allergens (class 2 food allergy. Allergenicity of food is largely determined by structural aspects, including cross-reactivity and reduced or enhanced allergenicity with cooking that convey allergenic characteristics to food. Management of food allergy currently focuses on dietary avoidance of the offending foods, prompt recognition and treatment of allergic reactions, and nutritional support. This review includes definitions and examines the prevalence and management of food allergies and the characteristics of food allergens.

    On a population level, it is well recognized that some IgE-mediated childhood food allergies, such as milk and egg allergies, are more likely to resolve than others, such as peanut and tree nuts allergies. Unfortunately, some studies suggest that resolution rates may have slowed compared with impressions from past decades. The clinician can apply the knowledge of the epidemiology of these allergies to describe likely patient outcomes, and direct management in a general manner. However, the ability to evaluate and predict the natural course of specific food allergies for individual patients is essential to inform personalized patient care. Data are accumulating to assist in identifying whether a child's allergy has likely resolved, informing the timing of oral food challenges or subsequent testing. Exciting recent studies are increasingly identifying early prognostic markers as well. Emerging food allergy therapies carry risks and costs. Identifying which egg-allergic patient has likely persistent allergy, and which patient with peanut allergy may experience natural resolution, is becoming an important goal to identify the best candidates for these therapies. Although more work needs to be done to identify reliable predictive markers and validate them, there is already much known about the natural course of food allergies that can be applied by the clinician to improve patient care.

  11. Maternal prenatal and/or postnatal n-3 long chain polyunsaturated fatty acids (LCPUFA) supplementation for preventing allergies in early childhood.

    Science.gov (United States)

    Gunaratne, Anoja W; Makrides, Maria; Collins, Carmel T

    2015-07-22

    Allergies have become more prevalent globally over the last 20 years. Dietary consumption of n-3 (or omega 3) long chain polyunsaturated fatty acids (LCPUFA) has declined over the same period of time. This, together with the known role of n-3 LCPUFA in inhibiting inflammation, has resulted in speculation that n-3 LCPUFA may prevent allergy development. Dietary n-3 fatty acids supplements may change the developing immune system of the newborn before allergic responses are established, particularly for those with a genetic predisposition to the production of the immunoglobulin E (IgE) antibody. Individuals with IgE-mediated allergies have both the signs and symptoms of the allergic disease and a positive skin prick test (SPT) to the allergen. To assess the effect of n-3 LCPUFA supplementation in pregnant and/or breastfeeding women on allergy outcomes (food allergy, atopic dermatitis (eczema), allergic rhinitis (hay fever) and asthma/wheeze) in their children. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (6 August 2014), PubMed (1966 to 01 August 2014), CINAHL via EBSCOhost (1984 to 01 August 2014), Scopus (1995 to 01 August 2014), Web of Knowledge (1864 to 01 August 2014) and ClinicalTrials.gov (01 August 2014) and reference lists of retrieved studies. We included randomised controlled trials (RCTs) evaluating the effect of n-3 LCPUFA supplementation of pregnant and/or lactating women (compared with placebo or no treatment) on allergy outcomes of the infants or children. Trials using a cross-over design and trials examining biochemical outcomes only were not eligible for inclusion. Two review authors independently assessed eligibility and trial quality and performed data extraction. Where the review authors were also investigators on trials selected, an independent reviewer assessed trial quality and performed data extraction. Eight trials involving 3366 women and their 3175 children were included in the review. In these trials, women

  12. Severe forms of food allergy.

    Sarinho, Emanuel; Lins, Maria das Graças Moura

    To guide the diagnostic and therapeutic management of severe forms of food allergy. Search in the Medline database using the terms "severe food allergy," "anaphylaxis and food allergy," "generalized urticaria and food allergy," and "food protein-induced enterocolitis syndrome" in the last ten years, searching in the title, abstract, or keyword fields. Food allergy can be serious and life-threatening. Milk, eggs, peanuts, nuts, walnuts, wheat, sesame seeds, shrimp, fish, and fruit can precipitate allergic emergencies. The severity of reactions will depend on associated cofactors such as age, drug use at the onset of the reaction, history and persistence of asthma and/or severe allergic rhinitis, history of previous anaphylaxis, exercise, and associated diseases. For generalized urticaria and anaphylaxis, intramuscular epinephrine is the first and fundamental treatment line. For the treatment in acute phase of food-induced enterocolitis syndrome in the emergency setting, prompt hydroelectrolytic replacement, administration of methylprednisolone and ondansetron IV are necessary. It is important to recommend to the patient with food allergy to maintain the exclusion diet, seek specialized follow-up and, in those who have anaphylaxis, to emphasize the need to carry epinephrine. Severe food allergy may occur in the form of anaphylaxis and food-protein-induced enterocolitis syndrome, which are increasingly observed in the pediatric emergency room; hence, pediatricians must be alert so they can provide the immediate diagnosis and treatment.

    2016-07-01

    The concept of allergic reaction currently includes all those where an immunological reaction depends on a reaction mediated by IgE, as well as those that involve other immune mechanisms, such as T-cell regulators. There are many different clinical situations, like the classic immediate reactions (IgE mediated) such as urticaria, angioedema, immediate vomiting, abdominal pain, both upper respiratory (aphonia or rhinitis) and lower (wheezing or dyspnoea) symptom, and cardiovascular symptoms. The reactions that involve more than one organ, such as anaphylaxis, which could be an anaphylactic shock if there is cardiovascular involvement. The clinical signs and symptoms produced by non-IgE mediated reactions are usually more insidious in how they start, such as vomiting hours after the ingestion of food in enterocolitis, diarrhoea after days or weeks from starting food, dermatitis sometime after starting food. In these cases it is more difficult to associate these clinical symptoms directly with food. In this article, we attempt to clarify some concepts such as sensitisation/allergy, allergen/allergenic source, or the relationship of different clinical situations with food allergy, in order to help the paediatrician on the one hand, to prescribe strict diets in case of a suspicion based on the cause/effect relationship with the food, and on the other hand not to introduce unnecessary diets that very often have to last an excessively long time, and could lead to nutritional deficiencies in the children.

    With the exception of shellfish, the overall food allergy rates in Singapore have not reached the epidemic proportions of the West. The rates of egg, milk and fish allergies remain low. However, the patterns of some food allergies in Singapore have changed over the last decade. For example, peanut allergy, once rare in Singapore, is now the most common cause of anaphylaxis in children. Studies analysing lifestyle practices, particularly with respect to prevention of food allergy, are necessary in order for practitioners to understand global differences and maintain this low prevalence.

  11. Is caesarean delivery associated with sensitization to food allergens and IgE-mediated food allergy: a systematic review.

    Science.gov (United States)

    Koplin, Jennifer; Allen, Katie; Gurrin, Lyle; Osborne, Nicholas; Tang, Mimi L K; Dharmage, Shyamali

    2008-12-01

    Several studies have shown differences in the composition of the gastrointestinal flora of children who develop sensitization to food allergens compared with non-allergic children. It has been hypothesized that changes in the gut microbiota resulting from caesarean section delivery could increase a child's risk of developing food allergy; however, studies examining the relationship between mode of delivery and food allergy have produced conflicting results. The objective of this review was to determine whether there is sufficient evidence to support an association between delivery by caesarean section and the development of sensitization to food allergens and immunoglobulin E (IgE) mediated food allergy. Using predefined inclusion and exclusion criteria, MEDLINE and PubMed were searched for studies investigating the relationship between caesarean section delivery and food allergy. The information on the quality of the studies and results were extracted and analysed systematically. The search identified four relevant studies as per our protocol. Symptomatic food allergy was used as the outcome in two studies and was found to occur more frequently in children born by caesarean section in one study while the second study found no association between food allergy diagnoses and mode of delivery. The other two studies measured levels of food antigen-specific IgE, with both studies showing an increase in sensitization to food allergens among children born by caesarean section. Overall, there is evidence that the risk of developing IgE-mediated sensitization to food allergens is increased among children delivered by caesarean section, however further studies using objectively diagnosed food allergy as the outcome are needed to verify whether this equates to an increase in confirmed food allergy. Future birth cohort studies should control for the effects of mode of delivery when investigating environmental modifiers of food allergy.

  16. Gastrointestinal food allergies.

    Science.gov (United States)

    Heine, Ralf G

    2015-01-01

    Gastrointestinal food allergies present during early childhood with a diverse range of symptoms. Cow's milk, soy and wheat are the three most common gastrointestinal food allergens. Several clinical syndromes have been described, including food protein-induced enteropathy, proctocolitis and enterocolitis. In contrast with immediate, IgE-mediated food allergies, the onset of gastrointestinal symptoms is delayed for at least 1-2 hours after ingestion in non-IgE-mediated allergic disorders. The pathophysiology of these non-IgE-mediated allergic disorders is poorly understood, and useful in vitro markers are lacking. The results of the skin prick test or measurement of the food-specific serum IgE level is generally negative, although low-positive results may occur. Diagnosis therefore relies on the recognition of a particular clinical phenotype as well as the demonstration of clear clinical improvement after food allergen elimination and the re-emergence of symptoms upon challenge. There is a significant clinical overlap between non-IgE-mediated food allergy and several common paediatric gastroenterological conditions, which may lead to diagnostic confusion. The treatment of gastrointestinal food allergies requires the strict elimination of offending food allergens until tolerance has developed. In breast-fed infants, a maternal elimination diet is often sufficient to control symptoms. In formula-fed infants, treatment usually involves the use an extensively hydrolysed or amino acid-based formula. Apart from the use of hypoallergenic formulae, the solid diets of these children also need to be kept free of specific food allergens, as clinically indicated. The nutritional progress of infants and young children should be carefully monitored, and they should undergo ongoing, regular food protein elimination reassessments by cautious food challenges to monitor for possible tolerance development. © 2015 S.

    2017-01-01

    Full Text Available In recent years, there has been a significant increase in the prevalence  of food allergies. Pathological conditions associated  with a food intolerance are becoming an increasingly urgent problem of pediatrics. According to different researchers, allergic lesions of the gastrointestinal tract occurs in 25–50% of patients with such common pathology as an allergy to cow's milk proteins. The severity of diseases  associated  with food allergies and their prognosis  depend largely on early diagnosis and adequate treatment. Difficulties and errors  in the diagnosis  of gastrointestinal  food allergies  are associated  with both subjective  and objective  reasons,  primarily due to the fact that gastrointestinal  reactions to food are often delayed and non-IgE-mediated. The article describes clinical forms of gastrointestinal food allergy according to the existing classification. Diagnostic algorithms and modern approaches  to differential diagnosis of disease based on evidence-based  medicine and corresponding to international consensus papers are given.

  20. Severe forms of food allergy

    Directory of Open Access Journals (Sweden)

    Emanuel Sarinho

    Full Text Available Abstract Objectives: To guide the diagnostic and therapeutic management of severe forms of food allergy. Data sources: Search in the Medline database using the terms “severe food allergy,” “anaphylaxis and food allergy,” “generalized urticaria and food allergy,” and “food protein-induced enterocolitis syndrome” in the last ten years, searching in the title, abstract, or keyword fields. Summary of data: Food allergy can be serious and life-threatening. Milk, eggs, peanuts, nuts, walnuts, wheat, sesame seeds, shrimp, fish, and fruit can precipitate allergic emergencies. The severity of reactions will depend on associated cofactors such as age, drug use at the onset of the reaction, history and persistence of asthma and/or severe allergic rhinitis, history of previous anaphylaxis, exercise, and associated diseases. For generalized urticaria and anaphylaxis, intramuscular epinephrine is the first and fundamental treatment line. For the treatment in acute phase of food-induced enterocolitis syndrome in the emergency setting, prompt hydroelectrolytic replacement, administration of methylprednisolone and ondansetron IV are necessary. It is important to recommend to the patient with food allergy to maintain the exclusion diet, seek specialized follow-up and, in those who have anaphylaxis, to emphasize the need to carry epinephrine. Conclusion: Severe food allergy may occur in the form of anaphylaxis and food-protein-induced enterocolitis syndrome, which are increasingly observed in the pediatric emergency room; hence, pediatricians must be alert so they can provide the immediate diagnosis and treatment.

    To provide a review on spice allergy and its implementation in clinical practice. PubMed searches were performed using spice allergy as the keyword for original and review articles. Selected references were also procured from the reviewed articles' references list. Articles were selected based on their relevance to the topic. Spices are available in a large variety and are widely used, often as blends. Spice allergy seems to be rare, reportedly affecting between 4 and 13 of 10,000 adults and occurring more often in women because of cosmetic use. No figures were available on children. Most spice allergens are degraded by digestion; therefore, IgE sensitization is mostly through inhalation of cross-reacting pollens, particularly mugwort and birch. The symptoms are more likely to be respiratory when exposure is by inhalation and cutaneous if by contact. Studies on skin testing and specific IgE assays are limited and showed low reliability. The diagnosis primarily depends on a good history taking and confirmation with oral challenge. The common use of spice blends makes identifying the particular offending component difficult, particularly because their components are inconsistent. Spices are widely used and contain multiple allergens, yet spice allergy is probably markedly underdiagnosed. There is a need for reliable skin testing extracts and serum specific IgE assays. Currently, the diagnosis depends on a good history taking and well-designed titrated challenge testing. Until immunotherapy becomes developed, treatment is strict avoidance, which may be difficult because of incomplete or vague labeling.

    The science of food allergy has been rapidly evolving before our eyes in the past half century. Like other allergic disorders, the prevalence of food allergies has dramatically increased, and coupled with the increased public awareness of anaphylaxis due to food allergy, this has driven an explosion in basic and clinical research in this extremely broad subject. Treatment of food allergies has evolved and practices such as food challenges have become an integral part of an allergy practice. The impact of the increase of food allergy has driven package labeling laws, legislation on emergency treatment availability in schools and other public places, and school policy. But to this day, our knowledge of the pathogenesis of food allergy is still incomplete. There are the most obvious IgE-mediated immediate hypersensitivity reactions, but then multiple previously unidentified conditions such as eosinophilic esophagitis, food protein-induced enterocolitis syndrome, milk protein allergy, food-induced atopic dermatitis, oral allergy syndrome, and others have complicated the diagnosis and management of many of our patients who are unable to tolerate certain foods. Many of these conditions are not IgE-mediated, but may be T cell-driven diseases. The role of T regulatory cells and immune tolerance and the newly discovered immunological role of vitamin D have shed light on the variable clinical presentation of food allergy and the development of new methods of immunotherapy in an example of bench-to-bedside research. Component-resolved diagnostic techniques have already begun to allow us to more precisely define the epitopes that are targeted in food allergic patients. The development of biological modulators, research on genomics and proteomics, and epigenetic techniques all offer promising avenues for new modes of therapy of food allergy in the twenty-first century.

    Food allergies can result in life-threatening reactions and diminish quality of life. The prevalence of food allergies is increasing with large regional variability. A few food allergens cover the majority of food-related reactions (cow`s milk, egg, wheat, soy, fish, crustacean, nuts and peanut). Food reactions can be categorized in IgE-mediated and non-IgE-mediated, the latter of which remaining often a clue in the diagnosis. Treatment of food allergy involves mainly strict avoidance of the trigger food. Medications help to manage symptoms of disease, but currently, there is no cure for food allergy.

    Fish and its derived products play an important role in human nutrition, but they may also be a potent food allergen. Fish can be an ingested, contact, and inhalant allergen. Gad c I, a Parvalbumin, the major allergen in codfish, is considered as fish and amphibian pan-allergen. Prevalence of fish allergy appears to depend on the amount of fish eaten in the local diet. In Europe, the highest consumption occurs in Scandinavian countries, Spain and Portugal. In Spain, fish is the third most frequent allergen in children under 2 yr of age after egg and cow's milk. An adverse reaction to fish may be of non-allergic origin, due to food contamination or newly formed toxic products, but the most frequent type of adverse reactions to fish are immunologic-mediated reactions (allergic reactions). Such allergic reactions may be both IgE-mediated and non-IgE-mediated. Most cases are IgE-mediated, due to ingestion or contact with fish or as a result of inhalation of cooking vapors. Some children develop non-IgE-mediated type allergies such as food protein induced enterocolitis syndrome. The clinical symptoms related to IgE-mediated fish allergy are most frequently acute urticaria and angioedema as well as mild oral symptoms, worsening of atopic dermatitis, respiratory symptoms such as rhinitis or asthma, and gastrointestinal symptoms such as nausea and vomiting. Anaphylaxis may also occur. Among all the species studied, those from the Tunidae and Xiphiidae families appear to be the least allergenic.

    The gold standard test for confirming whether a child has clinical hypersensitivity reactions to foods is the oral food challenge. Therefore, there is increasing interest in simpler diagnostic markers of food allergy, especially in children, to avoid oral food challenge. The goal of this study was to assess the diagnostic accuracy of atopy patch test in comparison with oral food challenge. We investigated 243 children (mean age, 51 months) referred for evaluation of suspected egg or cow's milk allergy. Skin prick test and atopy patch test were carried out, and after a 2 weeks elimination diet, oral food challenge was performed. Two hundred and forty-three children underwent OFC to the suspected food. We found clinically relevant food allergies in 40 (65%) children to egg and in 22 (35%) to cow's milk. The sensitivity of skin prick test for both milk and egg was 92%, specificity 91%, positive predictive value 35%, and negative predictive value of 93%. Sensitivity, specificity, positive predictive value, and negative predictive value of atopy patch test for both milk and egg were 21%, 73%, 20%, and 74%, respectively. Our study suggests that there is insufficient evidence for the routine use of atopy patch test for the evaluation of egg and cow's milk allergy. OFC remains gold standard for the diagnosis of egg and milk allergy even in the presence of high costs in terms of both time and risks during application. © 2015 John Wiley & Sons A/S.

    The objective of this study was to investigate food allergens and prevalence rates of food allergies, followed by comparison of consumer attitudes and preferences regarding food allergy labeling by diagnosis of food allergies. A total of 543 individuals living in Seoul and Gyeonggi area participated in the survey from October 15 to 22 in 2013. The results show that the prevalence of doctor-diagnosed food allergies was 17.5%, whereas 6.4% of respondents self-reported food allergies. The most common allergens of doctor-diagnosed and self-reported food allergy respondents were peaches (30.3%) and eggs (33.3%), respectively, followed by peanuts, cow's milk, and crab. Regarding consumer attitudes toward food labeling, checking food allergens as an item was only significantly different between allergic and non-allergic respondents among all five items (P label, and addition of potential allergens) were necessary for an improved food allergen labeling system. PLSR analysis determined that the doctor-diagnosed group and checking of food allergens were positively correlated, whereas the non-allergy group was more concerned with checking product brands. An effective food labeling system is very important for health protection of allergic consumers. Additionally, government agencies must develop policies regarding prevalence of food allergies in Korea. Based on this information, the food industry and government agencies should provide clear and accurate food labeling practices for consumers.

    Antibiotic use in early life has been linked to disruptions in the microbiome. Such changes can disturb immune system development. Differences have been observed in the microbiota of children with and without allergies, but there have been few studies on antibiotic use and allergic disease. We evaluated associations of early-life antibiotic use with subsequent occurrence of food allergy and other allergies in childhood using electronic health record data. We used longitudinal data on 30 060 children up to age 7 years from Geisinger Clinic's electronic health record to conduct a sex- and age-matched case-control study to evaluate the association between antibiotic use and milk allergy, non-milk food allergies, and other allergies. For each outcome, we estimated conditional logistic regression models adjusting for race/ethnicity, history of Medical Assistance, and mode of birth delivery. Models were repeated separately for penicillins, cephalosporins and macrolides. There were 484 milk allergy cases, 598 non-milk food allergy cases and 3652 other allergy cases. Children with three or more antibiotic orders had a greater odds of milk allergy (Odds Ratio; 95% Confidence interval) (1.78; 1.28-2.48), non-milk food allergy (1.65; 1.27-2.14), and other allergies (3.07; 2.72-3.46) compared with children with no antibiotic orders. Associations were strongest at younger ages and differed by antibiotic class. We observed associations between antibiotic orders and allergic diseases, providing evidence of a potentially modifiable clinical practice associated with paediatric allergic disease. Differences by antibiotic class should be further explored, as this knowledge could inform paediatric treatment decisions. © 2016 John Wiley & Sons Ltd.

    Adverse reactions to foods are commonly implicated in the causation of ill health. However, foreign antigens, including food proteins and commensal microbes encountered in the gastrointestinal tract, are usually well tolerated. True food allergies, implying immune-mediated adverse responses to food antigens, do exist, however, and are especially common in infants and young children. Allergic reactions to food manifest clinically in a variety of presentations involving the gastrointestinal, cutaneous, and respiratory systems and in generalized reactions such as anaphylaxis. Both IgE-mediated and non-IgE-mediated immune mechanisms are recognized. Important advances in the clinical features underlying specific food hypersensitivity disorders are reviewed.

    Food allergies present numerous challenges to coping in everyday life. Even simple things like planning a lunch with a friend can be stressful for people with food allergies. But are some people more adversely impacted by having a food allergy than other people? This paper addressed this question by investigating whether individual differences in the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are related to food allergy-related problems in everyday life among adults with food allergies. Participants were 108 adults (85% female; mean age = 40.2; age range 18-87) with a physician-diagnosed food allergy [most commonly to gluten (54.6%), peanuts (21.3%), cow's milk (16.7%), and shellfish/seafood (16.7%)]. Participants completed an initial online survey that measured demographics, food allergy information, and personality traits using the Big Five Inventory (John et al., 1991). For 2 weeks, participants completed a daily online survey that queried the occurrence of 25 food allergy issues that day and participants' overall stress and mood that day. Neuroticism did not predict more frequent allergy issues or greater stress/poorer mood on days with more allergy issues. Instead, higher openness to experience predicted a range of issues including going hungry because there is no safe food available, problems finding suitable foods when grocery shopping, feeling anxious at social occasions involving food, being excluded, and feeling embarrassed and poorly understood about their food allergy. Conscientious people were less embarrassed or self-conscious about their food allergy, but they had more problems eating out, and their positive mood was more impaired by allergy issues than their less conscientious peers. Extraversion and agreeableness played minor roles. Personality testing can identify people that may have difficulty living with food allergies-such as those higher in openness to experience.

    The US Food and Drug Administration recommends against feeding infants human milk from unscreened donors, but sharing milk via the Internet is growing in popularity. Recipient infants risk the possibility of consuming contaminated or adulterated milk. Our objective was to test milk advertised for sale online as human milk to verify its human origin and to rule out contamination with cow's milk. We anonymously purchased 102 samples advertised as human milk online. DNA was extracted from 200 μL of each sample. The presence of human or bovine mitochondrial DNA was assessed with a species-specific real-time polymerase chain reaction assay targeting the nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 5 gene. Four laboratory-created mixtures representing various dilutions of human milk with fluid cow's milk or reconstituted infant formula were compared with the Internet samples to semiquantitate the extent of contamination with cow's milk. All Internet samples amplified human DNA. After 2 rounds of testing, 11 samples also contained bovine DNA. Ten of these samples had a level of bovine DNA consistent with human milk mixed with at least 10% fluid cow's milk. Ten Internet samples had bovine DNA concentrations high enough to rule out minor contamination, suggesting a cow's milk product was added. Cow's milk can be problematic for infants with allergy or intolerance. Because buyers cannot verify the composition of milk they purchase, all should be aware that it might be adulterated with cow's milk. Pediatricians should be aware of the online market for human milk and the potential risks. Copyright © 2015 by the American Academy of Pediatrics.

  7. Donkey milk production: state of the art

    Full Text Available Milk is one of the most common causes of food allergies among children under one year of age. No specific therapy exists for this allergy, and thus the only feasible response is to avoid assumption of milk and derived products. Studies conducted on the serum of children with hypersensi- tivity to milk have shown that caseins are the proteins with the greater allergenic potential. However, in some cases, children have also shown hypersensitivity to the β-lactoglobulines and to the α-lactal- bumins. When food intolerance is diagnosed in an infant, it is often necessary to impose a period of total parenteral feeding, followed by breast feeding, considered the most correct method of re-feeding. When human milk can not be given, alternative food sources must be sought. Clinical studies have demonstrated that donkey milk could substitute breast feeding in infants affected by severe Ig-E me- diated milk allergies. In these subjects, donkey milk is not only useful, but also safer than other types of milk. In fact donkey milk composition in lipids (high levels of linoleic and linolenic acid and pro- teins (low caseins content is very close to human milk. Lysozyme content in donkey milk resulted to be very high (mean value 1.0 mg/ml if compared to bovine (traces, caprine (traces and human milk. The high lysozyme content of donkey milk may be responsible of the low bacterial count reported in literature and also makes this milk suitable to prevent intestine infections to infants. Among seropro- teins, β-lactoglobulin and α-lactalbumin content in donkey milk was respectively 3.75 and 1.80 mg/ml and remained substancially the same during the different stages of lactation.

    The further increase of allergies in industrialized countries demands evidence-based measures of primary prevention. The recommendations as published in the guideline of 2004 were updated and consented on the basis of a systematic literature search. Evidence from the period February 2003-May 2008 was searched in the electronic databases Cochrane and MEDLINE as well as in reference lists of recent reviews and by contacting experts. The retrieved citations were screened for relevance first by title and abstract and in a second step as full paper. Levels of evidence were assigned to each included study and the methodological quality of the studies was assessed as high or low. Finally the revised recommendations were formally consented (nominal group process) by representatives of relevant societies and organizations including a self-help group. Of originally 4556 hits, 217 studies (4 Cochrane Reviews, 14 meta-analyses, 19 randomized controlled trials, 135 cohort and 45 case-control studies) were included and critically appraised. Grossly unchanged remained the recommendations on avoiding environmental tobacco smoke, breast-feeding over 4 months (alternatively hypoallergenic formulas for children at risk), avoiding a mold-promoting indoor climate, vaccination according to current recommendations, and avoidance of furry pets (especially cats) in children at risk. The recommendation on reducing the house dust mite allergen exposure as a measure of primary prevention was omitted and the impact of a delayed introduction of supplementary food was reduced. New recommendations were adopted concerning fish consumption (during pregnancy / breast-feeding and as supplementary food in the first year), avoidance of overweight, and reducing the exposure to indoor and outdoor air pollutants. The revision of this guideline on a profound evidence basis led to (1) a confirmation of existing recommendations, (2) substantial revisions, and (3) new recommendations. Thereby it is possible

Presentamos el caso de un varón con clínica de disfagia intermitente coincidiendo con la toma de quesos curados de oveja y cabra que precisó asistencia urgente tras la impactación de un comprimido de ibuprofeno a 30 cm de la arcada dentaria. El estudio practicado demostró la existencia de estenosis en el esófago a ese nivel con infiltración eosinofílica difusa y sensibilización a proteínas de la leche de cabra, oveja y vaca, con especial relevancia para la IgG bovina, lactoferrina y albúmina sérica. Tras tratamiento con fluticasona deglutida y medidas de evitación se consiguió la resolución del cuadro clínico y la desaparición de los eosinófilos en la mucosa.Eosinophilic esophagitis is an inflammatory disease of the esophagus characterized by the presence of high numbers of eosinophils in the esophageal mucosal layer (> 20 high-power field. It is uncommon in adults but in such cases intermittent dysphagia and food impaction are the most common presenting symptoms. We report the case of a male with long-standing intermittent dysphagia after eating selected goat and sheep cheese types, who required medical help following the impaction of an ibuprofen pill in the esophagus. A biopsy demonstrated the presence of eosinophilic inflammation, and allergy testing showed specific IgE against proteins in the milk of goats and sheep. Topical steroid therapy with oral fluticasone, and the elimination of these dairy products from the diet induced complete symptom resolution, and biopsy specimens taken 4 months later showed no eosinophils.

This paper addressed this question by investigating whether individual differences in the Big Five personality traits (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are related to food allergy-related problems in everyday life among adults with food allergies. Participants were 108 adults (85% female; mean age = 40.2; age range 18–87) with a physician-diagnosed food allergy [most commonly to gluten (54.6%), peanuts (21.3%), cow's milk (16.7%), and shellfish/seafood (16.7%)]. Participants completed an initial online survey that measured demographics, food allergy information, and personality traits using the Big Five Inventory (John et al., 1991). For 2 weeks, participants completed a daily online survey that queried the occurrence of 25 food allergy issues that day and participants' overall stress and mood that day. Neuroticism did not predict more frequent allergy issues or greater stress/poorer mood on days with more allergy issues. Instead, higher openness to experience predicted a range of issues including going hungry because there is no safe food available, problems finding suitable foods when grocery shopping, feeling anxious at social occasions involving food, being excluded, and feeling embarrassed and poorly understood about their food allergy. Conscientious people were less embarrassed or self-conscious about their food allergy, but they had more problems eating out, and their positive mood was more impaired by allergy issues than their less conscientious peers. Extraversion and agreeableness played minor roles. Personality testing can identify people that may have difficulty living with food allergies–such as those higher in openness to experience.

    Full Text Available The usage of the mare’s milk as functional food especial for children intolerant to cow’s milk, with neurodermitis, allergies and similar disorders desiring to improve the quality of life is fiercely debated for last decades but there were no scientific studies to suggest such use of mare’s milk based on scientific research. The objectives of this study were to determine similarities of mare’s milk in comparison with milk of ruminants (cattle, sheep and goat and human milk in terms of milk composition and protein fraction as whey proteins, caseins and micelles size. All differences were discussed regarding usage of mare’s milk in human diet and compared to milk which is usually used in human nutrition. Regarding composition, the mare’s milk is similar to human milk in of crude protein, salt and lactose content, but it has significantly lower content of fat. Fractions of main proteins are similar between human and mare’s milk, except nitrogen casein (casein N which has twice lower content in human than in mare’s milk. Content of casein N from all ruminants’ milk differ much more. Just for true whey N and non-protein nitrogen (NPN similar content as human and mare’s milk has also goat milk. The casein content is the lowest in human milk; this content is three times greater in mare’s milk and six to seven times greater in goat’s and cow’s milk, while in sheep’s milk it is more than 10 times grater. In many components and fractions mare’s milk is more similar to human milk than milk of ruminants. A detail comparison of protein fraction shows quite large differences between milk of different species. More study and clinical research are needed that can recommend usage of mare’s milk in human diet as functional food on scientific bases.

  14. Inhalant allergies in children.

    Science.gov (United States)

    Mims, James W; Veling, Maria C

    2011-06-01

    Children with chronic or recurrent upper respiratory inflammatory disease (rhinitis) should be considered for inhalant allergies. Risk factors for inhalant allergies in children include a first-degree relative with allergies, food allergy in infancy, and atopic dermatitis. Although inhalant allergies are rare in infancy, inhalant allergies are common in older children and impair quality of life and productivity. Differentiating between viral and allergic rhinitis can be challenging in children, but the child's age, history, and risk factors can provide helpful information. Allergic rhinitis is a risk factor for asthma, and if one is present, medical consideration of the other is warranted. Copyright © 2011 Elsevier Inc. All rights reserved.

  15. Debates in allergy medicine: food intolerance does not exist.

    Science.gov (United States)

    2015-01-01

    The term "intolerance" is not mentioned in the World Allergy Organization (WAO) document on allergy nomenclature. "Intolerance" has been used to describe some non-immunological diseases. However, pediatric gastroenterologists mix allergy and intolerance, e.g. by using the term "cow's milk protein allergy/intolerance (CMPA/I)", lumping together all types of mechanisms for not tolerating cow's milk. The basis for this mix is the fact that double-blind oral food challenges are time-consuming and expensive. Therefore, cow's milk exclusion and reintroduction is proposed to be used in primary care for the diagnosis of CMPA in children with common gastrointestinal (GI) problems such as colic and constipation. This may lead to a widespread use of hypoallergenic formulas in children without proven CMPA. In lay language, intolerance describes "not tolerating". To discuss the reasons why the term "intolerance" should not be used in the area of allergy. Presently, intolerance is not part of the allergy nomenclature. It is used by lay persons to describe "not tolerating". Pediatricians use intolerance to describe non-immunological hypersensitivity such as lactose intolerance which is acceptable. However, using the mixed term CMPA/I describing a variety of gastrointestinal symptoms in children, should be avoided. The WAO Nomenclature does not clearly distinguish between non-IgE-mediated allergy and non-allergic hypersensitivity. The term "intolerance" should not be used within the area of allergy. Intolerance should be better defined and the term restricted to some non-immunological/non-allergic diseases and not mixed with allergy, e.g. by using the term CMPA/I. A revision of the WAO nomenclature is proposed.

    Food allergies have increased in prevalence over the past 20 years, now becoming an important public health concern. Although there are no therapies currently available for routine clinical care, recent reports have indicated that immunotherapies targeting the mucosal immune system may be effective. Oral immunotherapy is conducted by administering small, increasing amounts of food allergen; it has shown promise for desensitizing individuals with peanut, egg, or milk allergies. Sublingual immunotherapy also desensitizes allergic patients to foods-2 major studies have examined the effects of sublingual immunotherapy in subjects with peanut allergies. We review the complex nature of IgE-mediated food allergies and the therapies being evaluated in clinical trials. We focus on the diagnosis and management of food allergies and investigational therapies. Copyright © 2015. Published by Elsevier Inc.

    Full Text Available Food allergy in children is increasing and the perception of food allergy among parents is even more common. In a questionnaire-based study of 702 children aged 6 to 48 months in four primary care settings, the aim was to determine the prevalence of perception vs. proven food allergy, parental anxiety and general pediatrician knowledge of food allergy. In 95/702 children (13.5% parentally-reported food was associated reactions. IgE and/or skin prick test (SPT and/or an open provocation test were performed in 48 (6.8% and allergy was proven in 38 (5.4% children. Discrepancy between parental perception and proven allergy is significant (p < 0.001, especially for food other than milk, egg and peanut (p < 0.001. Allergy to milk was the most common. Allergy to peanut was significantly more common in children ≥2 years (p < 0.05. Severe reactions occurred in 5/95 (5.2% of all children and in 5/38 (13.1% of allergic children, in 3/5 caused by peanut. Parents of children with proven allergy do not experience high degree of anxiety. The perception of food allergy among general pediatricians is limited, and in children with severe reactions precautionary measures and information to parents were insufficient. Parents and general pediatricians need additional education in food allergy.

    The ten-year Finnish national allergy programme was launched in 2008 to lessen the disease and psychological burden of allergy. This study assessed the prevalence of parent-reported food allergies requiring avoidance diets at primary school in children aged six and seven years. The cohort comprised 1937 children (51% boys) who started primary school in Tampere, Finland, in August 2016. School health nurses charted parent-reported, doctor-diagnosed food allergies requiring avoidance diets as part of the routine health examination. We found that 127 (6.6%) children had parent-reported, doctor-diagnosed allergies to at least one food and 37 (1.9%) were allergic to basic foods, namely cows' milk, wheat and one other grain. All required an avoidance diet. The figure did not differ significantly from the 2.7% and 2.5% found by studies of this age group in 2009 and 2013, respectively. Allergies to fresh fruit and vegetables decreased from 5.8% in 2009 to 3.6% in 2016. We studied the national allergy programme that started in 2008 and found that there was a nonsignificant overall decrease in the number of children aged six to seven years on avoidance diets for allergies between 2009 and 2016. The only allergies that showed significant decreases were fresh fruit and vegetables. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Antigenicity of proteins found in cow's milk is age dependent. This is primarily due to infants possessing a more permeable intestinal wall than that in adults. Thus infants may acquire cow's milk allergy during their first year of life. While milk antigen specific IgE may cause allergy in susceptible subjects, there is some evidence indicating that milk antigen specific IgG may play some role in chronic disease development. The puropose of this study was to determine the antigenicity of cow'...

However, the nutritional needs for appropriate growth and neurodevelopmental outcomes of such a particular population of infants should be attentively evaluated, considering also the indication to an appropriate fortification of human milk. The target is to achieve growth potential for preterm newborns while ensuring good metabolic outcomes and normal neurological development. When mother's milk is unavailable or in short supply, donor human milk (DHM represents the second best choice and, although somewhat modified by the Holder pasteurization process, it preserves many benefits when compared to formula, as documented by more and more reports, randomized controlled trials, and meta-analyses published in the past few years. Evidence exists of the protection exerted by DHM from necrotizing enterocolitis, while further studies are required to look at possible beneficial effects regarding infections, bronchopulmonary dysplasia, long-term cardiovascular risk factors, feeding tolerance, neurological outcome, and allergy. Finally, the concern that the use of DHM might decrease preterm infant breastfeeding is being raised. Conversely, publications exist showing that the use of DHM in the neonatal unit increases breastfeeding rates at discharge for infants of very low birth weight.

    To examine the effects of food avoidance on the growth of children with food allergies. A retrospective chart review was performed for children with and without food allergies followed at 2 New York City general pediatric practices. Charts were selected based on codes from the International Classification of Diseases, 9th Revision, for well child visit, food allergy, anaphylaxis, and/or epinephrine autoinjector prescriptions. Heights and weights were obtained to calculate body mass index, height, and weight z-scores. Of the 9938 children seen, 439 (4.4%) were avoiding one or more foods. Of those with commercial insurance, children with food allergies were significantly shorter (mean height z-score = 0.06; P = .01) and weighed less (mean weight z-score -0.1; P = .006) than children without food allergies (mean height z-score = 0.42; mean weight z-score = 0.07). In contrast, children with food allergies and state insurance were not smaller in height or weight compared with children without food allergies. Among white subjects, there was a significant effect of food allergies on height and weight (ANOVA for height P = .012, for weight P = .0036) that was not observed for Hispanic/Latino, black, or Asian subjects. Children with allergies to milk weighed significantly less than children without milk allergies (P = .0006). Children with food allergies and commercial insurance have significant impairment in growth compared with those without food allergies. Additionally, children avoiding all forms of milk are shorter and weigh less than matched counterparts. Therefore, height and weight measurements should be assessed routinely in children with food allergies because there is risk for growth impairment in this population. Copyright © 2014 Elsevier Inc.

    The aim of the study was to explore prevalence of food allergies and intolerances among children in preschools in Reykjavik, Iceland. Also, to investigate how well preschools maintain a safe environment for children with food allergies. In 2014, a questionnaire designed specifically for this study, was sent to 65 preschools. Forty-nine participated (75%) representing a total of 4225 children. Prevalence of food allergy and intolerance was determined based on medical certificates from physi-cians delivered to the preschools. Descriptive statistics were used to assess whether there were protocols related to food allergy, and if there was a difference between schools based on staff's education and number of children. The prevalence of documented food allergies/intolerances in children aged 2-6 years was 5%, 1% had severe allergy and 1% had multiple food allergies. Lactose intolerance was most frequent (2%), then milk allergy (2%) and egg allergy (1%). Only 41% preschools had a protocol that was activated if food with an allergen was accidentally given. Moreover, only 55% of preschools with children with severe -allergy reported all of their staff to have knowledge of symptoms related to anaphylaxis and only 64% were trained to respond to an anaphylactic shock. The education of preschool principals, kitchen employees and number of children in preschool were not related to having an active protocol at site. Prevalence of food allergy and intolerance was 5% in preschools in Reykjavik. Strategy for an active protocol related to food allergy was lacking in 59% of pre-schools.

    Children have the highest rates of food-related allergic reactions. While 85% of children outgrow allergies including cow's milk and eggs by five years of age, allergies to peanuts and seafood continue into adulthood. The school setting poses a high-risk environment for allergen exposure. The aim of the present study was to examine the availability, drivers and communication of school food allergy awareness and management policies/guidelines in one Australian education jurisdiction. A cross-sectional study comprising an online survey of principals on school allergy awareness (n = 100) was conducted in public, catholic and independent primary and high schools in an Australian education jurisdiction between August 2011 and November 2012. Sixty-three per cent (17/27) of schools responding to the survey reported using food allergy management guidelines. An average of 13 students per school were reported to have a food allergy with 93% of schools reported having students with at least one food allergy. Parents, not government policy, were identified as primary drivers of food allergy guideline implementation and a third of schools provided anaphylaxis training annually. Communication of food allergy management was limited with only 42 school websites either providing access to policies/guidelines or providing a food allergy statement. Detailed awareness and management guidelines are integral for schools to adequately manage food-induced allergic reactions, including anaphylaxis, in the school environment. To enable this, national government support through legislation and policy is needed to ensure a consistent, up-to-date and policed approach to food allergy management in the Australian education sector. © 2015 Dietitians Association of Australia.

  20. Amiata donkey milk chain: animal health evaluation and milk quality

    Full Text Available This study presents an investigation of Amiata donkey health and quality of milk for human consumption. Thirty-one lactating dairy jennies were examined. The following samples were collected: faecal samples from the rectum of animals for parasitological examination; cervical swabs for the detection of bacteria causing reproductive disorders; and blood samples for serological diagnosis of main zoonotic (Brucella spp., Leptospira spp. and donkey abortion agents (Brucella spp., Leptospira spp., Salmonella abortus equi, Equine viral arterithis virus, Equine herpesvirus type 1. In addition, individual milk samples were collected and analysed for mastitis- causing pathogens and milk quality. Regarding animal health, we detected a high prevalence of strongyle parasites in donkeys. It is very important to tackle parasitic diseases correctly. Selective control programmes are preferable in order to reduce anthelmintic drug use. For dairy donkeys, withdrawal periods from anthelmintic drugs need to be carefully managed, in accordance with EU and national regulations. The isolation of Staphylococcus aureus in milk highlights the importance of preventing contamination during milking, by adopting appropriate hygiene and safety practices at a farm level. Lysozyme activity was high compared to cow’s milk, contributing to the inhibitory activity against certain bacteria. Donkey milk was characterised by high lactose content, low caseins, low fat, higher levels of unsaturated fatty acids compared to ruminant milks. Unsaturated fatty acids and omega 3 fatty acids in particular have become known for their beneficial health effect, which is favourable for human diet. These characteristics make it suitable for infants and children affected by food intolerance/ allergies to bovine milk proteins and multiple food allergies as well as for adults with dyslipidemias. It is also recommended to prevent cardiovascular diseases.

    Food allergy heavily impairs quality of life. Avoiding the offending food requires extensive patient education. Social media have been proven a useful source of information for other chronic conditions. Our aim was to describe how pediatric patients with food allergy and their families are using social media. We performed a cross-sectional study in the Pediatric Allergy Unit of a third-level hospital. Patients with food allergy were surveyed about their disease and the use of social media. Patients over 13 years filled in the survey themselves, while parents or guardians did in the case of younger patients. We included 193 patients (162 guardians, 31 adolescents). Social media was used by 109 guardians (67.3%) and 29 adolescents (90.3%), of which 30.3% and 6.9%, respectively, used them for food allergy-allergy related purposes. Most popular websites were Facebook™ for guardians (52.2%) and YouTube™ among teenagers (80.6%). Having cow's milk and/or egg allergy was the only feature related to using social media for food allergy. Utilizing social media for food allergy information, did not correlate with the frequency of recent reactions, self-scored knowledge about food allergy or the opinion on evidence-based or alternative therapies for their disease. Most patients and guardians of patients with food allergy used social media. However, only a small portion accessed them for increasing the knowledge of their disease.

    Full Text Available Scientific evidence is accumulating to prove the nutritional, anti-infective, anti-fertility, psychosomal and economic advantages of breast-feeding. A number of studies have shown that breast milk protects against diarrheal, respiratory and other infections. Its value in protecting against allergy has also been established. This article reviews the studies on various immune defence factors present in the human milk. The available scientific knowledge makes a very strong case in favour of promoting breast-feeding.

    Many consider food allergy as the "second wave" of the allergy epidemic following the "first wave" of respiratory allergy, i.e., asthma and allergic rhinitis, plaguing westernized countries, with up to 8% of young children and 2%-3% of adults in the United States now affected by hypersensitivity reactions to various foods. In the past decade, there have been great strides in our understanding of the underlying immunopathogenesis of these disorders, which have led to improved diagnostic techniques, management strategies, and therapeutic approaches. Here we will review the most recent understanding of basic mechanisms underlying IgE-mediated food allergies and novel therapeutic approaches under investigation for both the prevention and treatment of IgE-mediated food allergies.

  10. Moral Considerations in Pediatric Food Allergies

    Full Text Available Food allergies are common health problem among children. They carry a significant risk of severe allergic reactions. These disorders are chronic conditions in which the immune system becomes hypersensitive to some food products. It is estimated that 8% of children under the age of three have a type of food allergy. The common allergenic foods include cow’s milk, wheat, peanuts, egg, soy and fish.The mainstay of treatment is to eliminate the allergenic food from the patient’s diet which in case of a child mandates special behavioral and ethical problems. Considering the growing incidence of food allergy, and the risk of anaphylaxis, diverse moral-ethical challenges face parents, school administrators and health professionals. Older children have the right to keep the fact of their disease private and this is a matter of their autonomy and may be an effort to prevent stigmatization by other students followed by psychosocial discomfort.Some moral & ethical principles in implementing management guidelines for allergic children include: -Imagine if the patient was your own. What level of protection would you expect for him/her? -Do protective policies cause the child to be isolated from others? -Are medical recordings confidential? -Avoid unduly limiting the diet of these children. A certain scenario is an infant with cow milk allergy. In this condition specific consideration should be paid to the mother’s nutritional status when a dietary elimination strategy is to be implemented. Considering the costs /benefits of diagnostic and therapeutic measures in food allergic children is recommended.

    Food allergies can newly arise in adulthood or persist following a food allergy occurring in childhood. The prevalence of primary food allergy is basically higher in children than in adults; however, in the routine practice food allergies in adulthood appear to be increasing and after all a prevalence in Germany of 3.7 % has been published. The clinical spectrum of manifestations of food allergies in adulthood is broad. Allergy symptoms of the immediate type can be observed as well as symptoms occurring after a delay, such as indigestion, triggering of hematogenous contact eczema or flares of atopic dermatitis. The same principles for diagnostics apply in this group as in childhood. In addition to the anamnesis, skin tests and in vitro tests, as a rule elimination diets and in particular provocation tests are employed. Molecular allergy diagnostics represent a major step forward, which allow a better assessment of the risk of systemic reactions to certain foodstuffs (e.g. peanuts) and detection of cross-reactions in cases of apparently multiple sensitivities. Current German and European guidelines from 2015 are available for the practical approach to clarification of food allergies. The most frequent food allergies in adults are nuts, fruit and vegetables, which can cross-react with pollen as well as wheat, shellfish and crustaceans. The therapy of allergies involves a consistent avoidance of the allogen. Detailed dietary plans are available with avoidance strategies and instructions for suitable food substitutes. A detailed counseling of affected patients by specially trained personnel is necessary especially in order to avoid nutritional deficiencies and to enable patients to enjoy a good quality of life.

    During the last decades, the world has witnessed a dramatic increase in allergy prevalence. Epidemiological evidence shows that growing up on a farm is a protective factor, which is partly explained by the consumption of raw cow's milk. Indeed, recent studies show inverse associations between raw cow's milk consumption in early life and asthma, hay fever, and rhinitis. A similar association of raw cow's milk consumption with respiratory tract infections is recently found. In line with these f...

    2005-05-02

    A family history of allergy and asthma identifies children at high risk of allergic disease. Dietary restrictions in pregnancy are not recommended. Avoiding inhalant allergens during pregnancy has not been shown to reduce allergic disease, and is not recommended. Breastfeeding should be recommended because of other beneficial effects, but if breast feeding is not possible, a hydrolysed formula is recommended (rather than conventional cow's milk formulas) in high-risk infants only. Maternal dietary restrictions during breastfeeding are not recommended. Soy formulas and other formulas (eg, goat's milk) are not recommended for reducing food allergy risk. Complementary foods (including normal cow's milk formulas) should be delayed until a child is aged at least 4-6 months, but a preventive effect from this measure has only been demonstrated in high-risk infants. There is no evidence that an elimination diet after age 4-6 months has a protective effect, although this needs additional investigation. Further research is needed to determine the relationship between house dust mite exposure at an early age and the development of sensitisation and disease; no recommendation can yet be made about avoidance measures for preventing allergic disease. No recommendations can be made about exposure to pets in early life and the development of allergic disease. If a family already has pets it is not necessary to remove them, unless the child develops evidence of pet allergy (as assessed by an allergy specialist). Women should be advised not to smoke while pregnant, and parents should be advised not to smoke. No recommendations can be made on the use of probiotic supplements (or other microbial agents) for preventing allergic disease at this time. Immunotherapy may be considered as a treatment option for children with allergic rhinitis, and may prevent the subsequent development of asthma.

    Full Text Available Although food allergy is a major public health problem, currently there is no effective and safe treatment except to avoid the foods .But the need for new options is critical now as the number of children diagnosed with food allergies rises. Avoiding the offending allergen in the diet is the primary treatment of food allergy. Once a food to which the patient is sensitive has been identified, the food must be removed from the diet. People with severe food allergies must be prepared to treat an anaphylactic reaction. These individuals also always should carry a syringe of adrenaline (epinephrine [EpiPen], and be prepared to self-administer it if they think they are developing an allergic reaction. Several medications are available for treating the other symptoms of food allergy. For example, antihistamines can relieve gastrointestinal symptoms, hives, sneezing, and a runny nose. Bronchodilators can relieve the symptoms of asthma. They are not effective, however, in preventing an allergic reaction when taken prior to eating the food. In fact, no medication in any form is available to reliably prevent an allergic reaction to a certain food before eating that food.Novel therapeutic approaches to food allergy can be classified as food allergen-specific therapy(immunotherapy with native or modified recombinant allergens, or oral desensitization or food allergen-nonspecifictherapy (anti-IgE, traditional Chinese medicine.   Key Words: Children, Food Allergy, Management.

    There is uncertainty about the prevalence of food allergy in communities. To assess the prevalence of food allergy by performing a meta-analysis according to the method of assessment used. The foods assessed were cow's milk, hen's egg, peanut, fish, shellfish, and an overall estimate of food allergy. We summarized the information in 5 categories: self-reported symptoms, specific IgE positive, specific skin prick test positive, symptoms combined with sensitization, and food challenge studies. We systematically searched MEDLINE and EMBASE for publications since 1990. The meta-analysis included only original studies. They were stratified by age groups: infant/preschool, school children, and adults. A total of 934 articles were identified, but only 51 were considered appropriate for inclusion. The prevalence of self-reported food allergy was very high compared with objective measures. There was marked heterogeneity between studies regardless of type of assessment or food item considered, and in most analyses this persisted after age stratification. Self-reported prevalence of food allergy varied from 1.2% to 17% for milk, 0.2% to 7% for egg, 0% to 2% for peanuts and fish, 0% to 10% for shellfish, and 3% to 35% for any food. There is a marked heterogeneity in the prevalence of food allergy that could be a result of differences in study design or methodology, or differences between populations. We recommend that measurements be made by using standardized methods, if possible food challenge. We need to be cautious in estimates of prevalence based only on self-reported food allergy.

    This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace. Exposure to animal allergens can result in allergy, asthma, and anaphylaxis. Animal allergy has been most studied in the research laboratory setting, where exposure reduction can prevent the development of allergy. Similar prevention approaches need to be considered for other animal work environments and in all settings where animal allergens are present.

    IgE- mediated food allergy affects 6-8% of children. Our study aimed to define the correlations between the results obtained with skin prick tests (SPTs) using commercial extracts and fresh foods, and the correlations between these result and those obtained with specific IgE (sIgE) and/ or challenge. Children aged from 2 months to 6 years were recruited prospectively. Overall 571 children were positive to one food. In all children we performed  SPT using commercial extracts of suspected food and fresh foods and sIgE. If SPT and sIgE test results did not correspond to the history, we performed open oral food challenge. Sensitivity of SPT with commercial extracts for all tested food was poor (3-35%), while  sensitivity of fresh food skin prick tests (FFSPT) was excellent (50-100%), and showed correlation with open oral food challenge (pfood extracts are more effective in detecting sensitization and with levels of sIgE greater than class 3 could predict clinical reactivity, without the need for potentially hazardous food challenges.

    Many parents of food allergic children have concerns about the development of food allergies in their other children. We sought to determine prevalence of food sensitization and clinical food allergy among siblings of food allergic children. Two thousand eight hundred and thirty-four children were enrolled in the Chicago Family Cohort Food Allergy study. One thousand one hundred and twenty children (ages 0-21 years) with a food allergy (defined by a reported reaction history and evidence of food-specific IgE or skin prick test) and at least 1 biological sibling were included in this study. Among siblings of children with food allergy, 33.4% had no sensitization and no clinical symptoms to food. Fifty-three percent had a positive food serum-specific IgE or skin prick test, but no reported symptoms of food allergy. Only 13.6% of siblings were both sensitized and clinically reactive to the same food. Milk allergy was the most common allergy among siblings (5.9%), followed by egg allergy (4.4%) and peanut allergy (3.7%). In a large cohort of food allergic families, only a small proportion of siblings were both sensitized and clinically reactive to a food. Sensitization without reactivity was common among siblings. Testing for food allergy in siblings without a history of clinical reactivity appears to be unjustified. Screening may lead to negative consequences related to potential misdiagnosis and unnecessary avoidance of a food. More data are needed to determine the absolute risk of food allergy development in siblings of food allergic children. Copyright © 2016 American Academy of Allergy, Asthma & Immunology.

    Fish and shellfish consumption has increased worldwide, and there are increasing reports of adverse reactions to fish and shellfish, with an approximate prevalence of 0.5-5%. Fish allergy often develops early in life, whilst shellfish allergy tends to develop later, from adolescence onwards. Little is known about the natural history of these allergies, but both are thought to be persistent. The clinical manifestations of shellfish allergy, in particular, may vary from local to life-threatening 'anaphylactic' reactions within an individual and between individuals. Parvalbumin and tropomyosin are the two major allergens, but several other allergens have been cloned and described. These allergens are highly heat and biochemically stable, and this may in part explain the persistence of these allergies. Diagnosis requires a thorough history, skin prick and in-vitro-specific IgE tests, and oral challenges may be needed for diagnostic confirmation. Strict avoidance of these allergens is the current standard of clinical care for allergic patients, and when indicated, an anaphylactic plan with an adrenaline auto-injector is prescribed. There are no published clinical trials evaluating specific oral immunotherapy for fish or shellfish allergy. © 2015 S. Karger AG, Basel.

    It is well recognized that atopic sensitization is an important risk factor for asthma, both in adults and in children. However, the role of allergy in severe asthma is still under debate. The term 'Severe Asthma' encompasses a highly heterogeneous group of patients who require treatment on steps 4-5 of GINA guidelines to prevent their asthma from becoming 'uncontrolled', or whose disease remains 'uncontrolled' despite this therapy. Epidemiological studies on emergency room visits and hospital admissions for asthma suggest the important role of allergy in asthma exacerbations. In addition, allergic asthma in childhood is often associated with severe asthma in adulthood. A strong association exists between asthma exacerbations and respiratory viral infections, and interaction between viruses and allergy further increases the risk of asthma exacerbations. Furthermore, fungal allergy has been shown to play an important role in severe asthma. Other contributing factors include smoking, pollution and work-related exposures. The 'Allergy and Asthma Severity' EAACI Task Force examined the current evidence and produced this position document on the role of allergy in severe asthma. © 2016 John Wiley & Sons A/S.

    Baked egg and baked milk are tolerated by most children who are allergic to hen's egg and cow's milk. Incorporating baked goods into the diets of allergic children may help them outgrow their primary allergy more quickly, with changes observed akin to immunotherapy. Benefits may also include increased quality of life and improved nutritional status. The search for a reliable biomarker to predict tolerance to baked goods is ongoing. Most children with a milk or egg allergy who are not previously tolerating egg or milk in baked goods should be offered an observed oral food challenge. Copyright © 2017 Elsevier Inc.

    Orchard workers in north China are highly exposed to orchard pollens, especially peach and other Rosaceae family pollens during pollination season. The aim of this study was to investigate whether occupational allergy to peach tree pollen as a member of Rosaceae family is IgE-mediated and to evaluate the cross-reactivity among Rosaceae family pollens. Allergen skin test and conjunctival challenge test were performed; enzyme linked immune-sorbent assay (ELISA), inhibiting ELISA, western immunoblotting and inhibiting western immunoblotting were done with Rosaceae family orchard pollens, including peach, apricot, cherry, apple and pear tree pollens. Mass spectrometry was also performed to probe the main allergen component and cross-reactive protein. Sensitizations to peach pollen were found in both skin test and conjunctival challenge in the patients. Serum specific IgE to three pollens (peach, apricot and cherry) were detected through ELISA. When peach pollen used as solid phase, ELISA inhibition revealed other four kinds of pollens capable of inducing partial to strong inhibitions (45% to 87%), with the strongest inhibition belonging to apricot pollen (87%). Western blotting showed predominant IgE binding to a 20 KD protein among these pollens, which appeared to be a cross-reactive allergen component through western blotting inhibition. It was recognized as a protein homologous to glutathione s-transferase 16 from Arabidopsis thaliana. Peach and other Rosaceae family tree pollen may serve as a potential cause of IgE mediated occupational respiratory disease in orchard workers in north China.

    Food protein-induced allergic proctocolitis is a frequent cause of rectal bleeding in infants. Characteristics of infants with multiple food allergies have not been defined. This study aimed to identify characteristics of infants with proctocolitis and compare infants with single and multiple food allergies. A total of 132 infants with proctocolitis were evaluated retrospectively. All of the infants were diagnosed by a paediatric allergist and/or a paediatric gastroenterologist according to guidelines. Clinical features of the infants, as well as results of a complete blood count, skin prick test, specific immunoglobulin E, and stool examinations or colonoscopy were recorded. Cow's milk (97.7%) was the most common allergen, followed by egg (22%). Forty-five (34.1%) infants had allergies to more than one food. Infants with multiple food allergies had a higher eosinophil count (613±631.2 vs. 375±291.9) and a higher frequency of positive specific IgE and/or positive skin prick test results than that of patients with a single food allergy. Most of the patients whose symptoms persisted after two years of age had multiple food allergies. There is no difference in clinical presentations between infants with single and multiple food allergies. However, infants with multiple food allergies have a high blood total eosinophil count and are more likely to have a positive skin prick test and/or positive specific IgE results.

    To conduct a survey on self-reported food allergy to milk, egg, peanuts, tree nuts, fish, shellfish, wheat, and sesame, as well as reported food-related anaphylaxis and epinephrine prescription practices among Kuwaiti students attending Kuwait University. One thousand questionnaires that included data on age, gender, presence of food allergies, and associated details were distributed. All participants reporting an allergy were categorized as having a perceived food allergy. Those with a convincing clinical history and history of undergoing diagnostic food allergy testing were further categorized as having a probable food allergy. Of the 1,000 questionnaires, 865 (86.5%) were completed. Of the 865 students, 104 (12.02%) reported food allergy (perceived), and 47 of these (45.19%) were probable food allergies. For milk (46.7%), peanut (35.7%), fish (60%), and sesame (50%), probable food allergy occurred in early childhood (≤5 years) while those of egg (44.4%) and wheat (57.1%) occurred in late childhood (6-10 years), and shellfish (40%) occurred in early adolescence (11-15 years). Of the 47 students with a probable food allergy, 28 (59.6%) were moderate to severe: 20 (71%) of these moderate-to-severe allergy cases reported at least 1 food-related anaphylactic episode while 8 (29%) denied such episodes. Equally important, of the 28 students, 6 (21%) received an autoinjectable epinephrine prescription, while 22 (79%) did not receive any. In this study the reported occurrence of perceived food allergy was low and probable food allergy occurred mostly in early childhood. Milk, egg, and nut allergies were the most commonly reported in both groups. © 2017 S. Karger AG, Basel.

It is a major cause of anaphylaxis in the Middle East and is the third most common food allergen in Israel. We conducted a systematic review of original articles published in the last 10 years regarding the diagnosis and management of sesame allergy. Skin prick testing appears to be a useful predictor of sesame allergy in infants, although data are less consistent in older children and adults. The diagnostic capacity of serum-specific immunoglobulin E is poor, especially in studies that used oral food challenges to confirm the diagnosis. Double-blind, placebo-controlled food challenge thus remains the diagnostic gold standard for sesame allergy. The cornerstone of sesame allergy management is allergen avoidance, though accidental exposures are common and patients must be prepared to treat the consequent reactions with epinephrine. Novel diagnostic and treatment options such as component-resolved diagnostics, basophil activation testing, and oral immunotherapy are under development but are not ready for mainstream clinical application.

    2003-01-01

    A change of protein in irradiated food has been known. There are a few reports on change of allergy of irradiated foods. Two kinds of allergy such as the immediate allergy (I type) and delayed allergy (IV type) are taken ill by foods. I type is related to irradiated foods. Allergen enters body through digestive tract. Anti body (IgE) is protein with from 10,000 to 100,000 molecular weight. Allergic disease is originated mainly by egg, milk, wheat, buckwheat, peanut and shrimp. When food is irradiated, the proteins are decomposed and produced higher and lower molecular compounds at the same time. Change of the viscosity and the sedimentation coefficient and deactivation of enzymes of β-lactoglobulin, cow albumin, egg albumin and casein were investigated. There is no report of increasing allergy by irradiation. However, some paper indicated that immunogenicity of protein was decreased by irradiation. (S.Y.)

    2012-01-01

    The aim of this paper is to review the current literature on allergy in orthodontics and to identify the predisposing factors and the implications of the allergic reaction in the management of patients during orthodontic treatment. A computerized literature search was conducted in PubMed for articles published on allergy in relation to orthodontics. The MeSH term used was allergy and orthodontics. Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. Current evidence suggests that the most common allergic reaction reported in orthodontics is related to nickel in orthodontic appliances and allergic response is more common in women due to a previous sensitizing exposure from nickel in jewellery. Studies have implicated allergy in the etiology of hypo-dontia. It has also been considered as a high-risk factor for development of extensive root resorption during the course of orthodontic treatment. This review discusses the relationship and implications of allergy in orthodontics. PMID:24987632

  5. Lettuce contact allergy.

    2016-02-01

    Lettuce (Lactuca sativa L.) and its varieties are important vegetable crops worldwide. They are also well-known, rarely reported, causes of contact allergy. As lettuce allergens and extracts are not commercially available, the allergy may be underdiagnosed. The aims of this article are to present new data on lettuce contact allergy and review the literature. Lettuce is weakly allergenic, and occupational cases are mainly reported. Using aimed patch testing in Compositae-allergic patients, two recent Danish studies showed prevalence rates of positive lettuce reactions of 11% and 22%. The majority of cases are non-occupational, and may partly be caused by cross-reactivity. The sesquiterpene lactone mix seems to be a poor screening agent for lettuce contact allergy, as the prevalence of positive reactions is significantly higher in non-occupationally sensitized patients. Because of the easy degradability of lettuce allergens, it is recommended to patch test with freshly cut lettuce stem and supplement this with Compositae mix. As contact urticaria and protein contact dermatitis may present as dermatitis, it is important to perform prick-to-prick tests, and possibly scratch patch tests as well. Any person who is occupationally exposed to lettuce for longer periods, especially atopics, amateur gardeners, and persons keeping lettuce-eating pets, is potentially at risk of developing lettuce contact allergy. © 2015 John Wiley & Sons A/S.

    Traidl-Hoffmann, Claudia

    2017-06-01

    The increase in allergies is a phenomenon that is being observed in all fast-developing countries. For a long time, science has taken as a starting point that solely a genetic predisposition is a precondition for the development of an allergy. Today, knowledge of environmental factors that can alter genes or the transcription of genes in the cells, has improved. Epidemiological studies have meanwhile identified several environmental factors that have a protective or supporting effect on allergy development. The environmental microbiome has recently gained central interest. A common theme in most of the studies is diversity: reduced diversity is correlated with enhanced risk for chronic inflammatory diseases and allergy.It is now of great interest for research to further analyze such environment-gene and/or environment-human interactions on all levels - from organs to cells to small and microstructures such as genes. For immunologists, it is specifically about understanding the influencing factors and effector pathways of allergens, and to apply thereby obtained insights in the follow-up for the ultimate goal of allergy research - prevention.

  7. Fish allergy: in review.

    2014-06-01

    Globally, the rising consumption of fish and its derivatives, due to its nutritional value and divergence of international cuisines, has led to an increase in reports of adverse reactions to fish. Reactions to fish are not only mediated by the immune system causing allergies, but are often caused by various toxins and parasites including ciguatera and Anisakis. Allergic reactions to fish can be serious and life threatening and children usually do not outgrow this type of food allergy. The route of exposure is not only restricted to ingestion but include manual handling and inhalation of cooking vapors in the domestic and occupational environment. Prevalence rates of self-reported fish allergy range from 0.2 to 2.29 % in the general population, but can reach up to 8 % among fish processing workers. Fish allergy seems to vary with geographical eating habits, type of fish processing, and fish species exposure. The major fish allergen characterized is parvalbumin in addition to several less well-known allergens. This contemporary review discusses interesting and new findings in the area of fish allergy including demographics, novel allergens identified, immunological mechanisms of sensitization, and innovative approaches in diagnosing and managing this life-long disease.

  8. The Prevalence of Eosinophilic Esophagitis in Pediatric Patients with IgE-Mediated Food Allergy.

    Hill, David A; Dudley, Jesse W; Spergel, Jonathan M

    Eosinophilic esophagitis (EoE) is an allergic inflammatory disease that is triggered by food allergens and characterized by progressive esophageal dysfunction. Recently, EoE has been identified in patients who underwent oral immunotherapy (OIT) for IgE-mediated food allergy, suggesting an association. We sought to ascertain whether significant associations exist between IgE-mediated food allergies and EoE. Using the analysis of electronic medical record data and manual chart review, we examined our subspecialty care network of 35,528 children and adolescents to identify and characterize patients with IgE-mediated and EoE food allergy. The most common food allergens were defined, and the prevalence of EoE in patients with IgE-mediated food allergy was determined. Logistic regression was used to measure the extent to which IgE-mediated food allergy to specific foods is associated with EoE. The most common causes of EoE were milk, soy, egg, grains, and meats, an allergen pattern that is distinct from that of IgE-mediated food allergy. The prevalence of EoE in patients with IgE-mediated food allergy was higher than that reported in the general population (4.7% vs 0.04%). The distribution of IgE-mediated food allergens in patients with EoE was similar to that of the general population, and IgE-mediated allergy to egg (2.27; 1.91-2.64), milk (4.19; 3.52-4.97), or shellfish (1.55; 1.24-1.92) was significantly associated with an EoE diagnosis. Our findings support a clinical association between these conditions that has implications for the management of children with food allergy, and particular relevance to patients undergoing OIT.

    Full Text Available Milk, an essential source of offspring nourishment, varies in it’s composition and properties significantly across species. In human nutrition, fresh milk and dairy products are valuable sources of protein, fat and energy, and are an important part of daily meals. Most of the world’s milk production (85 % comes from cows followed by buffaloes, goats, ewes, mares and donkeys. However milk related food allergies in infants may be a reason for health problems and may cause a decrease in milk. The objective of this paper was to give an overview of the overall composition of milk and fat from different species in comparison to women milk. Regarding the overall milk composition remarkable differences in energy content, fat, lactose, protein and ash of the various milks were found, but also some similarities among milk from ruminants and non-ruminants were detected. The structures of fat globule membranes were similar among non-ruminants and women milk, while the milk fat globule structure in ruminants differed significantly. The size of fat globules was significantly different between species and highly correlated to the milk fat content, regardless of the specie. The amount of triacylglycerols was notably higher, while the amount of free fatty acids and phospholipids was notably lower in milk from ruminants and women compared to milk from mares and donkeys. The triacylglycerol structure in women and non-ruminantsˈ was similar. The percentage of saturated and monounsaturated fatty acids was lower, while the unsaturated fatty acid content was higher in milk from non-ruminants, with a remarkably higher percentage of C-18:2 and C-18:3. The cholesterol content was similar in women and ruminantsˈ milk, but lower in that of non-ruminants. This review indicates that milk from non-ruminants could be more suitable for human nourishment than milk from ruminants.

    Dairy and milk consumption are frequently included as important elements in a healthy and balanced diet. It is the first food for mammals and provides all the necessary energy and nutrients to ensure proper growth and development, being crucial in respect to bone mass formation. However, several controversies arise from consumption of dairy and milk products during adulthood, especially because it refers to milk from other species. Despite these controversies, epidemiologic studies confirm the nutritional importance of milk in the human diet and reinforce the possible role of its consumption in preventing several chronic conditions like cardiovascular diseases (CVDs), some forms of cancer, obesity, and diabetes. Lactose malabsorption symptoms and cow milk protein allergy are generally considered to be the adverse reactions to milk consumption. The present article reviews the main aspects of milk nutritional composition and establishes several associations between its nutritious role, health promotion, and disease prevention.

    Full Text Available Camel milk and camel milk products have always been highly esteemed playing even today an important role in the diet of the population in the rural areas of Africa, Asia and the Middle East, with scarce agricultural areas, high temperatures and small amount of precipitation. In aggravated environmental circumstances, camels may produce more milk than any other species, while their demand for food is very modest. A camel produces between 1000 and 2000 L of milk during the lactation period of 8 to 18 months, while the daily production of milk is between 3 and 10 L. The goal of the overview is to present the chemical composition of camel milk, and products made from camel milk. On average camel milk contains 81.4-87 % water, 10.4 % dry matter, 1.2-6.4 % milk fat, 2.15-4.90 % protein, 1.63-2.76 % casein, 0.65-0.80 % whey protein, 2.90-5.80 % lactose and 0.60-0.90 % ash. Variations in the contents of camel milk may be attributed to several factors such as analytical methods, geographical area, nutrition conditions, breed, lactation stage, age and number of calvings. Camel milk is becoming an increasingly interesting product in the world, not only for its good nutritive properties, but also for its interesting and tasteful products.

    In last 30 to 40 years there has been a significant increase in the incidence of allergy. This increase cannot be explained by genetic factors alone. Increasing air pollution and its interaction with biological allergens along with changing lifestyles are contributing factors. Dust mites, molds, and animal allergens contribute to most of the sensitization in the indoor setting. Tree and grass pollens are the leading allergens in the outdoor setting. Worsening air pollution and increasing particulate matter worsen allergy symptoms and associated morbidity. Cross-sensitization of allergens is common. Treatment involves avoidance of allergens, modifying lifestyle, medical treatment, and immunotherapy. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background: Plant-origin foods are among the most important sources of food allergic reactions. An increase in the incidence of sesame seed allergy among children and adults has been reported in recent years. The aim of this preliminary study was to investigate the prevalence, importance and clinical manifestations of sesame allergy among Iranian patients.Methods: In a cross-sectional survey, 250 patients with suspected IgE-mediated food allergies completed a questionnaire and underwent skin prick tests with sesame extract as well as cross-reacting foods (walnut, soya and peanut. Total IgE and sesame-specific IgE levels were measured. Patients with positive skin test reactions and/or IgE specific for sesame without clinical symptoms were considered sensitive to sesame. The patients who also had clinical symptoms with sesame consumption were diagnosed as allergic to sesame.Results: Of the 250 patients enrolled in this study, 129 were male and 121 female, with a mean age of 11.7 years. The most common food allergens were cow's milk, egg, curry, tomato and sesame. Sesame sensitivity was found in 35 patients (14.1%. Only five patients (2% had sesame allergy. Sesame-sensitive patients had a significantly higher frequency of positive prick test to cross-reacting foods when compared to non-sensitized patients (p=0.00. The type of symptom was independent of gender and age of the patients, but urticaria and dermatitis-eczema were significantly more frequent in sensitized patients (p=0.008.Conclusions: This is the first study addressing the prevalence of sesame seed allergy in Iranian population. We found sesame to be a common and important cause of food allergy. The panel of foods recommended for use in diagnostic allergy tests should be adjusted.

    Silvia Vincenzetti

    2014-06-01

    Full Text Available Cow's milk protein allergy (CMPA is an abnormal immunological response to cow milk proteins, which results in IgE-mediated reactions. The therapeutic strategy to respond to CMPA envisages the total elimination of milk or the administration of cow's milk substitutes. For this reason the use of milk from other mammalian species was tested. Among them, donkey's milk proved to be the best alternative in feeding infants affected by CMPA, since its chemical composition is comparable to human milk. In this work an in vitro study was performed in order to analyze the IgE reactivity to milk protein allergens from cow, donkey and goat. In particular, immunoblotting experiments using sera from milk-allergic and non-allergic adult volunteers were conducted with the aim of verifying the hypoallergenic property of donkey's milk. This study provided a preliminary evidence of the hypoallergenicity of donkey's milk when compared to bovine and goat milk. Considering the obtained results, it would be possible to develop a sensitive diagnostic method for CMPA detection, based on chromatographic and immunoblotting analysis.

    Allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish constitutes the majority of food allergy reactions, but reliable estimates of their prevalence are lacking. This systematic review aimed to provide up-to-date estimates of their prevalence in Europe.Studies published in Europe from January 1, 2000, to September 30, 2012, were identified from searches of four electronic databases. Two independent reviewers appraised the studies and extracted the estimates of interest. Data were pooled using random-effects meta-analyses. Fifty studies were included in a narrative synthesis and 42 studies in the meta-analyses. Although there were significant heterogeneity between the studies, the overall pooled estimates for all age groups of self-reported lifetime prevalence of allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish were 6.0% (95% confidence interval: 5.7-6.4), 2.5% (2.3-2.7), 3.6% (3.0-4.2), 0.4% (0.3-0.6), 1.3% (1.2-1.5), 2.2% (1.8-2.5), and 1.3% (0.9-1.7), respectively. The prevalence of food-challenge-defined allergy to cow's milk, egg, wheat, soy, peanut, tree nuts, fish, and shellfish was 0.6% (0.5-0.8), 0.2% (0.2-0.3), 0.1% (0.01-0.2), 0.3% (0.1-0.4), 0.2% (0.2-0.3), 0.5% (0.08-0.8), 0.1% (0.02-0.2), and 0.1% (0.06-0.3), respectively. Allergy to cow's milk and egg was more common among younger children, while allergy to peanut, tree nuts, fish, and shellfish was more common among the older ones. There were insufficient data to compare the estimates of soy and wheat allergy between the age groups. Allergy to most foods, except soy and peanut, appeared to be more common in Northern Europe. In summary, the lifetime self-reported prevalence of allergy to common foods in Europe ranged from 0.1 to 6.0%. The heterogeneity between studies was high, and participation rates varied across studies reaching as low as food allergies and initiating strategies to increase participation will advance this evidence base. © 2014

    Full Text Available Background. Atopic allergy is effected by a number of environmental exposures, such as dry air and time spent outdoors, but there are few estimates of the prevalence in populations from sub-arctic areas. Objective. To determine the prevalence and severity of symptoms of food, inhalation and skin-related allergens and coeliac disease (CD in the sub-arctic region of Sweden. To study the correlation between self-reported allergy and allergy test results. To estimate the heritability of these estimates. Study design. The study was conducted in Karesuando and Soppero in Northern Sweden as part of the Northern Sweden Population Health Study (n=1,068. We used a questionnaire for self-reported allergy and CD status and measured inhalation-related allergens using Phadiatop, food-related allergens using the F×5 assay and IgA and IgG antibodies against tissue transglutaminase (anti-tTG to indicate prevalence of CD. Results. The prevalence of self-reported allergy was very high, with 42.3% reporting mild to severe allergy. Inhalation-related allergy was reported in 26.7%, food-related allergy in 24.9% and skin-related allergy in 2.4% of the participants. Of inhalation-related allergy, 11.0% reported reactions against fur and 14.6% against pollen/grass. Among food-related reactions, 14.9% reported milk (protein and lactose as the cause. The IgE measurements showed that 18.4% had elevated values for inhalation allergens and 11.7% for food allergens. Self-reported allergies and symptoms were positively correlated (p<0.01 with age- and sex-corrected inhalation allergens. Allergy prevalence was inversely correlated with age and number of hours spent outdoors. High levels of IgA and IgG anti-tTG antibodies, CD-related allergens, were found in 1.4 and 0.6% of participants, respectively. All allergens were found to be significantly (p<3e–10 heritable, with estimated heritabilities ranging from 0.34 (F×5 to 0.65 (IgA. Conclusions. Self-reported allergy

    Recently, the incidence rates of childhood allergies have been rising around the world. The presence of persistent chemical pollutants in the environment and exposure to air pollutants are often cited as potential causes of childhood allergies. Accordingly, epidemiological studies of the associations between exposure to low levels of pollutants and adverse health effects are essential. However, at present no useful biomarkers for evaluating such associations have been developed. Thus, using a molecular epidemiological approach we planned to identify candidate biomarkers of pollutant-induced adverse health effects that can be used in children. In asthmatic children, we found that the serum levels of several polychlorinated biphenyl (PCB) congener sub-types were significantly positively correlated with interleukin (IL)-8 mRNA expression, whereas in a sub-group of children who displayed positive immunoglobulin E (IgE) responses to milk or egg proteins IL-22 mRNA expression was demonstrated to be useful for detecting the adverse health effects of environmental pollutants, particularly PCB congeners. In conclusion, the mRNA expression levels of IL-8 and IL-22 can be used to detect children who are at particular risk of adverse health events caused by environmental pollutants, especially PCBs.

    Experiments in order to induce food allergy were carried out in guinea pigs. The sensitization with egg albumin, pasteurized cow milk and bovine serum albumin provoked anaphylactic shock. The passive cutaneous anaphylaxis, serum antibodies, liver cytochrome P-450 concentration and the anaphylactic shock were determined. Some correlation between the mortality, anaphylactic antibodies and cytochrome P-450 monooxygenase system was established. The morphology of the jejunal mucosa, the activities of 5 disaccharidases, the number of immunoglobulin secreting cells (Ig SC) and the mastocytes were investigated in 35 patients with food allergy. Normal mucosa was found in 28 cases as well as a significant decrease of the lactase, sucrase and trehalase activities. An increase of IgM and IgG secreting cells and of mastocytes, different electron microscopic changes in the enterocytes (an increased number of lysosomes, appearance of vesicles in cytoplasma, shortening, enlargement and uneven distribution of microvilli) as well as symptoms of functional activity in the plasmocytes and some others were also revealed. The experimental model obtained is similar to that one in humans according to the enteral way of sensitization the high selectivity of the allergic reaction which is of reagin type as the immunoglobulin changes are involved.

  13. ORAL ALLERGY SYNDROME

    Directory of Open Access Journals (Sweden)

    A. V. Sergeev

    2011-01-01

    Full Text Available Abstract. Oral allergy syndrome (OAS is defined as a set of clinical manifestations caused by IgE-mediated allergic  reactions  that  occur  at  oral  and  pharyngeal  mucosae  in  the  patients  with  pollen  sensitization  after ingestion of certain fruits, vegetables, nuts and spices. OAS arises from cross-reactivity between specific pollen and food allergens, due to similarity of a configuration and amino acid sequence of allergenic molecules. OAS is considered as class II food allergy, being caused by thermo- and chemolabile allergens, and it is rarely combined with generalized manifestations of food allergy. Prevalence and spectrum of the causal allergens depend on a kind of pollen sensitization. In Moscow region, as well as in Northern Europe, allergic sensitization most commonly occurs to the pollen of leaf trees, whereas OAS is mostly connected with ingestion of fruits from Rosaceae family and nuts. Since last years, a newly developed technique of component-resolved molecular diagnosis (CR diagnostics allows of more precise detection of OAS-causing allergen molecules. These data are of extreme importance for administration of adequate nutritional therapy and prediction of SIT efficiency. (Med. Immunol., 2011, vol. 13, N 1, pp 17-28

    Soy sauce is well-known as a Japanese traditional seasoning, namely shoyu. Usually, shoyu means sauce made from soy. Shoyu does have not only benefits but also adverse effects. Soy sauce allergy which is not caused by soy or wheat allergy is rare. Our four patients developed cellulites and dermatitis around lips with irritation after a meal with shoyu. The age of the patients was 10, 35, 46 and 51 years; they were all female. These inflammations can be developed by two causes; first it can be caused by allergic reactions to shoyu; the second, it can be caused by histamine poisoning. It is important to determine whether inflammation is caused by allergic reactions or histamine poisoning. We determined the volume of histamine in some sauces and performed prick test and laboratory tests. Four patients had positive reactions by prick test after using some sauces. We suspected that histamine caused their symptoms, but nine normal volunteers had negative reactions. Patient's specific IgE score to soy and wheat was class 0. The results showed that the sauce made from soybean and broad bean contained histamine, but histamine in other sauces was not detected. In this study, we confirmed by prick test, four cases of soy sauce allergy, which was caused by some products during brewing. When patients with inflammations around mouth, after a meal containing or using soy sauce, are examined, it should be considered whether dermatitis or cellulites were developed by allergic reaction or by histamine poisoning.

  15. Globalisation and allergy.

    Science.gov (United States)

    Castelain, Michel

    2011-01-01

    Globalisation brings patients more and more into contact with products or food from other cultures or countries. Europeans may be confronted with allergens not yet known in Europe - such as dimethylfumarate - responsible for contact allergy epidemics. Moreover, "low cost" goods, not always legally imported into Europe, sometimes may lead to European legislation being circumvented and thus bring our patients into contact with components that have been banned from manufacturing processes or strongly regulated, such as nickel in jewelry or telephones, some colouring agents in clothes or preservatives in cosmetics. Disinfection measures for freight containers arriving from other continents into our harbours lead to fumigants and other toxic products contaminating the air and the transported products or goods. Globalisation can not only elicit contact allergy but also airborne contact dermatitis or food allergy. The aim of this paper is not to make an exhaustive review of cutaneous allergic problems elicited by globalisation, but to illustrate this new worldwide problem with a few meaningful examples.

    The prevalence of IgE-mediated food allergy and anaphylaxis has risen rapidly in developed countries, and countries with rapid industrialization may follow. Therapies include elimination diets, Oral ImmunoTherapy, and the administration of biologics, but high serum IgE levels may preclude their use. Consequently, decreasing IgE becomes a rational approach and could be obtained by immunoapheresis. The aim of this review is to evaluate the rationale and advantages of immunoapheresis. The majority of the available adsorbers remove aspecifically all classes of immunoglobulins. Recently, IgE-specific adsorbers have been approved. Data on immunoapheresis for the treatment of allergic diseases with pathologically elevated IgE levels are emerging. In atopic dermatitis, this therapy alone seems to be beneficial. IgE-selective apheresis appears to be sufficient to reduce the risk of anaphylaxis in multiple food allergy (MFA) and, when IgE titers are high, to open the way to treatment with Omalizumab. Prospective studies, with well designed protocols, are needed to assess the efficacy, tolerability, and cost-effectiveness of immunoapheresis in the field of food allergy.

    Full Text Available The continued increase in the incidence of allergic diseases in children population generates reasonable interest of allergists. The article describes the basic mechanisms of immunological response in light of the allergy risk modulation in children. It discusses a new approach to the prescription of hypoallergenic diets for healthy pregnant and lactating women to prevent allergies in children. A separate section examines the influence of the infant feeding mode in the first months of life on the risk of formation of allergies as a child grows, as well as key mechanisms for the formation of the oral tolerance phenomenon. The results from the study of immunological processes that underlie the phenomenon of oral tolerance confirm the ability to reduce the risk of formation of cow's milk protein allergy in formula-fed infants by using formulas based on hydrolysed protein.

    Exposure to microbes may be important in the development of atopic disease. Atopic diseases have been associated with specific characteristics of the intestinal microbiome. The link between intestinal microbiota and food allergy has rarely been studied, and the gold standard for diagnosing food allergy (double-blind placebo-controlled food challenge [DBPCFC]) has seldom been used. We aimed to distinguish fecal microbial signatures for food allergy in children with atopic dermatitis (AD). Pediatric patients with AD, with and without food allergy, were included in this cross-sectional observational pilot study. AD was diagnosed according to the UK Working Party criteria. Food allergy was defined as a positive DBPCFC or a convincing clinical history, in combination with sensitization to the relevant food allergen. Fecal samples were analyzed using 16S rRNA microbial analysis. Microbial signature species, discriminating between the presence and absence food allergy, were selected by elastic net regression. Eighty-two children with AD (39 girls) with a median age of 2.5 years, and 20 of whom were diagnosed with food allergy, provided fecal samples. Food allergy to peanut and cow's milk was the most common. Six bacterial species from the fecal microbiome were identified, that, when combined, distinguished between children with and without food allergy: Bifidobacterium breve, Bifidobacterium pseudocatenulatum, Bifidobacterium adolescentis, Escherichia coli, Faecalibacterium prausnitzii, and Akkermansia muciniphila (AUC 0.83, sensitivity 0.77, specificity 0.80). In this pilot study, we identified a microbial signature in children with AD that discriminates between the absence and presence of food allergy. Future studies are needed to confirm our findings. © 2018 The Author(s) Published by S. Karger AG, Basel.

    Full Text Available Background: A few reports demonstrate the comorbidity of food allergy and allergic march in adult patients. Aims and Objectives: To evaluate, if there is some relation in atopic dermatitis patients at the age 14 years and older who suffer from food allergy to common food allergens to other allergic diseases and parameters as bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. Materials and Methods: Complete dermatological and allergological examination was performed; these parameters were examined: food allergy (to wheat flour, cow milk, egg, peanuts and soy, the occurrence of bronchial asthma, allergic rhinitis, duration of atopic dermatitis, family history and onset of atopic dermatitis. The statistical evaluation of the relations among individual parameters monitored was performed. Results: Food allergy was altogether confirmed in 65 patients (29% and these patients suffer significantly more often from bronchial asthma and allergic rhinitis. Persistent atopic dermatitis lesions and positive data in family history about atopy are recorded significantly more often in patients with confirmed food allergy to examined foods as well. On the other hand, the onset of atopic dermatitis under 5 year of age is not recorded significantly more often in patients suffering from allergy to examined foods. Conclusion: Atopic dermatitis patients suffering from food allergy suffer significantly more often from allergic rhinitis, bronchial asthma, persistent eczematous lesions and have positive data about atopy in their family history.

    Full Text Available Background: Despite many efforts, the etiology of autism remains unknown. Food allergy has been suggested as a pathogenic factor in Autism Spectrum Disorder (ASD. Our aim in this study was to determine whether food allergy could be considered as a risk factor for autistic children. Methods: Thirty-nine autistic children were examined by the skin prick test (SPT, and total serum IgE was evaluated by ELISA. SPTs were performed for egg whites, oranges, peanuts, tomatoes, tuna fish, walnuts, aubergines, melons, grapes, and cow milk. Parents and teachers were then asked to exclude these items from the childrens’ diets for six months. After the treatment period, the autistic children who tested positive for food allergies were re-assessed by a standard questionnaire to obtain further information about their medical histories. Results: Three of the study’s 39 autistic children (7.7% tested positive on the SPT. Total serum IgE levels were elevated in 56.4% of the subjects (mean=164±24.5, cut-off >155 IU/ml. The results showed a decreased mean in the childrens’ autistic behaviors on the Children Autism Rating Scale (CARS after both eight weeks and six months; however, this decrease was not statistically significant. Conclusion: Food allergy may play a role in the pathophysiology of autism. We conclude that avoidance of certain foods benefits the behavior of autistic children.

    Full Text Available The prevalence of exotic pet allergies has been increasing over the last decade. Years ago, the main allergy-causing domestic animals were dogs and cats, although nowadays there is an increasing number of allergic diseases related to insects, rodents, amphibians, fish, and birds, among others. The current socio-economic situation, in which more and more people have to live in small apartments, might be related to this tendency. The main allergic symptoms related to exotic pets are the same as those described for dog and cat allergy: respiratory symptoms. Animal allergens are therefore, important sensitizing agents and an important risk factor for asthma. There are 3 main protein families implicated in these allergies, which are the lipocalin superfamily, serum albumin family, and secretoglobin superfamily. Detailed knowledge of the characteristics of allergens is crucial to improvement treatment of uncommon-pet allergies.

    Impairment of growth has been reported in food-allergic children. It is not known whether this is related to the extent of food allergies. We sought to compare growth, nutritional status, and nutrient intake in children with food allergy either avoiding cow's milk or avoiding cow's milk and wheat, which are staples of the diet in young children. Infants and young children with challenge-proven allergy were recruited to this prospective study. They were strictly avoiding their allergic food triggers, either cow's milk, or cow's milk and wheat. They were counseled by a dietitian specialized in food allergies on food avoidance diets and nutritionally adequate supplementation at regular intervals. A 3-day food diary was kept. Children's height, weight, and laboratory data for nutritional parameters were monitored at 8-month intervals. A total of 18 patients avoiding milk and 28 patients avoiding milk and wheat were evaluated at an average of 12, 21, and 28 months of age. During the follow-up, the markers of nutritional status, nutrient intake or height for age, and weight for height were comparable between the two groups, although the means for anthropometric measures were below the average for age in both groups. The extent of food elimination diet has no impact on growth or nutritional status of food-allergic children, when diet is adequately supplemented. Close physician and dietitian follow-up are essential for food-allergic children when avoiding one or more foods, which are staples of the diet. © 2015 John Wiley & Sons A/S.

  6. Food allergy: is prevalence increasing?

    Science.gov (United States)

    Tang, Mimi L K; Mullins, Raymond J

    2017-03-01

    It is generally accepted that the prevalence of food allergy has been increasing in recent decades, particularly in westernised countries, yet high-quality evidence that is based on challenge confirmed diagnosis of food allergy to support this assumption is lacking because of the high cost and potential risks associated with conducting food challenges in large populations. Accepting this caveat, the use of surrogate markers for diagnosis of food allergy (such as nationwide data on hospital admissions for food anaphylaxis or clinical history in combination with allergen-specific IgE (sIgE) measurement in population-based cohorts) has provided consistent evidence for increasing prevalence of food allergy at least in western countries, such as the UK, United States and Australia. Recent reports that children of East Asian or African ethnicity who are raised in a western environment (Australia and United States respectively) have an increased risk of developing food allergy compared with resident Caucasian children suggest that food allergy might also increase across Asian and African countries as their economies grow and populations adopt a more westernised lifestyle. Given that many cases of food allergy persist, mathematical principles would predict a continued increase in food allergy prevalence in the short to medium term until such time as an effective treatment is identified to allow the rate of disease resolution to be equal to or greater than the rate of new cases. © 2017 Royal Australasian College of Physicians.

    1993-02-01

    The belief that milk produces mucus is widespread in the community and is associated with a significant reduction in milk consumption. Sensations associated with milk drinking were reported by otherwise healthy believers and non-believers in the milk-mucus effect (N = 169) in an unstructured interview, with further responses prompted about the duration, type and amount of milk causing the effect. The site predominantly affected was the throat, with sensations related to difficulty in swallowing and perceived thickness of mucus and salivary secretions, rather than excessive mucus production. The effect required only a small amount of milk and was reported to be of short duration. The chronic respiratory symptom history and dairy product intake of 130 of these subjects were also assessed. Milk-mucus believers were different from non-believers, reporting more respiratory symptoms and consuming less milk and dairy products. Symptoms consistent with the known effects of food allergy or intolerance were not reported.

    2004-03-01

    Milk and dairy products are part of a healthy Mediterranean diet which, besides cow's milk, also consists of sheep's, goat's and buffalo's milk--alone or as a mixture---as raw material. The fat and protein composition of the milk of the various animal species differs only slightly, but in every case it has a high priority in human nutrition. The milk proteins are characterized by a high content of essential amino acids. Beyond that macromolecules,which have various biological functions, are available or may be formed by proteolysis in milk. Taking this into consideration, the technology of different well-known Italian and German cheese types is presented and the differences as well as correspondences regarding nutrition are discussed. Especially Ricotta and Mascarpone are discussed in detail. Ricotta represents a special feature as this cheese is traditionally made of whey and cream. Thus the highly valuable whey proteins which contain a higher amount of the amino acids lysine, methionine and cysteic acid in comparison to casein and, additionally, to soy protein, are made usable for human nutrition. Finally, it is pointed out on the basis of individual examples that technologies to enrich whey proteins in cheese are already available and in use. Thus, the flavor of low fat cheese is improved and the nutritional value is increased.

    Environmental changes are thought to be the main factor in the rapid increase and worsening of allergic diseases. While there have been significant changes in many environmental factors, including in environments such as residential, health and sanitation, food, and water/soil/atmospheric environments, the root of each of these changes is likely an increase in chemical substances. In fact, various environmental pollutants, such as air pollutants and chemical substances, have been shown to worsen various allergies in experimental studies. For example, diesel exhaust particles (DEPs), which are an agglomeration of particles and a wide array of chemical substances, aggravate asthma, primarily due to the principle organic chemical components of DEPs. In addition, environmental chemicals such as phthalate esters, which are commonly used as plasticizers in plastic products, also aggravate atopic dermatitis. It has also become evident that extremely small nanomaterials and Asian sand dust particles can enhance allergic inflammation. While the underlying mechanisms that cause such aggravation are becoming clearer at the cellular and molecular levels, methods to easily and quickly evaluate (screen) the ever-increasing amount of environmental pollutants for exacerbating effects on allergies are also under development. To eliminate and control allergic diseases, medical measures are necessary, but it is also essential to tackle this issue by ameliorating environmental changes.

    Alterations in the intestinal microbiome are prospectively associated with the development of asthma; less is known regarding the role of microbiome alterations in food allergy development. Intestinal microbiome samples were collected at age 3-6 months in children participating in the follow-up phase of an interventional trial of high-dose vitamin D given during pregnancy. At age 3, sensitization to foods (milk, egg, peanut, soy, wheat, walnut) was assessed. Food allergy was defined as caretaker report of healthcare provider-diagnosed allergy to the above foods prior to age 3 with evidence of IgE sensitization. Analysis was performed using Phyloseq and DESeq2; P-values were adjusted for multiple comparisons. Complete data were available for 225 children; there were 87 cases of food sensitization and 14 cases of food allergy. Microbial diversity measures did not differ between food sensitization and food allergy cases and controls. The genera Haemophilus (log 2 fold change -2.15, P=.003), Dialister (log 2 fold change -2.22, P=.009), Dorea (log 2 fold change -1.65, P=.02), and Clostridium (log 2 fold change -1.47, P=.002) were underrepresented among subjects with food sensitization. The genera Citrobacter (log 2 fold change -3.41, P=.03), Oscillospira (log 2 fold change -2.80, P=.03), Lactococcus (log 2 fold change -3.19, P=.05), and Dorea (log 2 fold change -3.00, P=.05) were underrepresented among subjects with food allergy. The temporal association between bacterial colonization and food sensitization and allergy suggests that the microbiome may have a causal role in the development of food allergy. Our findings have therapeutic implications for the prevention and treatment of food allergy. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

    The prevalence of food allergy is rising for unclear reasons, with prevalence estimates in the developed world approaching 10%. Knowledge regarding the natural course of food allergies is important because it can aid the clinician in diagnosing food allergies and in determining when to consider evaluation for food allergy resolution. Many food allergies with onset in early childhood are outgrown later in childhood, although a minority of food allergy persists into adolescence and even adulthood. More research is needed to improve food allergy diagnosis, treatment, and prevention. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study was carried out to evaluate the application of food irradiation technology as a method for reducing food allergy. Milk β-lactoglobulin, chicken egg albumin, and shrimp tropomyosin were used as model food allergens for experiments on allergenic and molecular properties by gamma irradiation. The amount of intact allergens in an irradiated solution was reduced by gamma irradiation depending upon the dose. These results showed that epitopes on the allergens were structurally altered by radiation treatment and that the irradiation technology can be applied to reduce allergenicity of allergic foods

  1. Primary Prevention of Food Allergy.

    Food allergy is estimated to affect approximately 8% of children in the USA. This is a disease without any known treatment or cure and, for some, a disease that can be quite severe, even life-threatening. While recent advances in potential treatment have made remarkable strides, with two food-targeted immunotherapy products now in phase III trials, perhaps the biggest gains in the field have come in the advent of potential preventative strategies to avoid the development of food allergy in high-risk individuals. There have been multiple, randomized, controlled trials (RCTs) performed in the past 5 years that have demonstrated significant risk reduction from early allergen introduction. These include two trials for early peanut introduction and five trials for early egg introduction in the first year of life. The results indicate that primary prevention of food allergy through early allergen introduction may represent a strategy that could potentially avert tens of thousands of children from becoming food allergic. In support of the data for peanut, the National Institute of Allergy and Infectious Diseases recently sponsored an addendum to the 2010 food allergy guidelines, specifically recommending peanut be introduced in both high- and standard-risk infants to reduce the risk of developing peanut allergy. To date, no formal recommendations have been made for egg, however. This review will focus on the latest evidence supporting early introduction as a strategy to prevent food allergy, as well as on practical aspects for its successful implementation.

    When drug reactions resembling allergy occur, they are called drug hypersensitivity reactions (DHRs) before showing the evidence of either drug-specific antibodies or T cells. DHRs may be allergic or nonallergic in nature, with drug allergies being immunologically mediated DHRs. These reactions are typically unpredictable. They can be life-threatening, may require or prolong hospitalization, and may necessitate changes in subsequent therapy. Both underdiagnosis (due to under-reporting) and overdiagnosis (due to an overuse of the term ‘allergy’) are common. A definitive diagnosis of such reactions is required in order to institute adequate treatment options and proper preventive measures. Misclassification based solely on the DHR history without further testing may affect treatment options, result in adverse consequences, and lead to the use of more-expensive or less-effective drugs, in contrast to patients who had undergone a complete drug allergy workup. Several guidelines and/or consensus documents on general or specific drug class-induced DHRs are available to support the medical decision process. The use of standardized systematic approaches for the diagnosis and management of DHRs carries the potential to improve outcomes and should thus be disseminated and implemented. Consequently, the International Collaboration in Asthma, Allergy and Immunology (iCAALL), formed by the European Academy of Allergy and Clinical Immunology (EAACI), the American Academy of Allergy, Asthma and Immunology (AAAAI), the American College of Allergy, Asthma and Immunology (ACAAI), and the World Allergy Organization (WAO), has decided to issue an International CONsensus (ICON) on drug allergy. The purpose of this document is to highlight the key messages that are common to many of the existing guidelines, while critically reviewing and commenting on any differences and deficiencies of evidence, thus providing a comprehensive reference document for the diagnosis and management of

  3. Food allergies in developing and emerging economies: need for comprehensive data on prevalence rates

    2012-12-01

    Full Text Available Abstract Although much is known today about the prevalence of food allergy in the developed world, there are serious knowledge gaps about the prevalence rates of food allergy in developing countries. Food allergy affects up to 6% of children and 4% of adults. Symptoms include urticaria, gastrointestinal distress, failure to thrive, anaphylaxis and even death. There are over 170 foods known to provoke allergic reactions. Of these, the most common foods responsible for inducing 90% of reported allergic reactions are peanuts, milk, eggs, wheat, nuts (e.g., hazelnuts, walnuts, almonds, cashews, pecans, etc., soybeans, fish, crustaceans and shellfish. Current assumptions are that prevalence rates are lower in developing countries and emerging economies such as China, Brazil and India which raises questions about potential health impacts should the assumptions not be supported by evidence. As the health and social burden of food allergy can be significant, national and international efforts focusing on food security, food safety, food quality and dietary diversity need to pay special attention to the role of food allergy in order to avoid marginalization of sub-populations in the community. More importantly, as the major food sources used in international food aid programs are frequently priority allergens (e.g., peanut, milk, eggs, soybean, fish, wheat, and due to the similarities between food allergy and some malnutrition symptoms, it will be increasingly important to understand and assess the interplay between food allergy and nutrition in order to protect and identify appropriate sources of foods for sensitized sub-populations especially in economically disadvantaged countries and communities.

    Sunflower seeds are a rare source of allergy, but several cases of occupational allergies to sunflowers have been described. Sunflower allergens on the whole, however, still await precise and systematic description. We present an interesting case of a 40-year-old male patient, admitted to hospital due to shortness of breath and urticaria, both of which appeared shortly after the patient ingested sunflower seeds. Our laryngological examination revealed swelling of the pharynx with retention of saliva and swelling of the mouth and tongue. During diagnostics, 2 months later, we found that skin prick tests were positive to mugwort pollen (12/9 mm), oranges (6/6 mm), egg protein (3/3 mm), and hazelnuts (3/3 mm). A native prick by prick test with sunflower seeds was strongly positive (8/5 mm). Elevated concentrations of specific IgE against weed mix (inc. lenscale, mugwort, ragweed) allergens (1.04 IU/mL), Artemisia vulgaris (1.36 IU/mL), and Artemisia absinthium (0.49 IU/mL) were found. An ImmunoCap ISAC test found an average level of specific IgE against mugwort pollen allergen component Art v 1 - 5,7 ISU-E, indicating an allergy to mugwort pollen and low to medium levels of specific IgE against lipid transfer proteins (LTP) found in walnuts, peanuts, mugwort pollen, and hazelnuts. Through the ISAC inhibition test we proved that sunflower seed allergen extracts contain proteins cross-reactive with patients’ IgE specific to Art v 1, Art v 3, and Jug r 3. Based on our results and the clinical pattern of the disease we confirmed that the patient is allergic to mugwort pollen and that he had an anaphylactic reaction as a result of ingesting sunflower seeds. We suspected that hypersensitivity to sunflower LTP and defensin-like proteins, both cross-reactive with mugwort pollen allergens, were the main cause of the patient’s anaphylactic reaction.

    Consumption of raw cow's milk instead of industrially processed milk has been reported to protect children from developing asthma, allergies, and respiratory infections. Several heat-sensitive milk serum proteins have been implied in this effect though unbiased assessment of milk proteins in general is missing. The aim of this study was to compare the native milk serum proteome between raw cow's milk and various industrially applied processing methods, i.e., homogenization, fat separation, pasteurization, ultra-heat treatment (UHT), treatment for extended shelf-life (ESL), and conventional boiling. Each processing method was applied to the same three pools of raw milk. Levels of detectable proteins were quantified by liquid chromatography/tandem mass spectrometry following filter aided sample preparation. In total, 364 milk serum proteins were identified. The 140 proteins detectable in 66% of all samples were entered in a hierarchical cluster analysis. The resulting proteomics pattern separated mainly as high (boiling, UHT, ESL) versus no/low heat treatment (raw, skimmed, pasteurized). Comparing these two groups revealed 23 individual proteins significantly reduced by heating, e.g., lactoferrin (log2-fold change = -0.37, p = 0.004), lactoperoxidase (log2-fold change = -0.33, p = 0.001), and lactadherin (log2-fold change = -0.22, p = 0.020). The abundance of these heat sensitive proteins found in higher quantity in native cow's milk compared to heat treated milk, renders them potential candidates for protection from asthma, allergies, and respiratory infections.

    Allergic diseases are on the increase globally in parallel with a decrease in parasitic infection. The inverse association between parasitic infections and allergy at an ecological level suggests a causal association. Studies in human subjects have generated a large knowledge base on the complexity of the interrelationship between parasitic infection and allergy. There is evidence for causal links, but the data from animal models are the most compelling: despite the strong type 2 immune responses they induce, helminth infections can suppress allergy through regulatory pathways. Conversely, many helminths can cause allergic-type inflammation, including symptoms of "classical" allergic disease. From an evolutionary perspective, subjects with an effective immune response against helminths can be more susceptible to allergy. This narrative review aims to inform readers of the most relevant up-to-date evidence on the relationship between parasites and allergy. Experiments in animal models have demonstrated the potential benefits of helminth infection or administration of helminth-derived molecules on chronic inflammatory diseases, but thus far, clinical trials in human subjects have not demonstrated unequivocal clinical benefits. Nevertheless, there is sufficiently strong evidence to support continued investigation of the potential benefits of helminth-derived therapies for the prevention or treatment of allergic and other inflammatory diseases.

    Horses develop many skin and respiratory disorders that have been attributed to allergy. These disorders include pruritic skin diseases, recurrent urticaria, allergic rhinoconjunctivitis, and reactive airway disease. Allergen-specific IgE has been detected in these horses, and allergen-specific immunotherapy is used to ameliorate clinical signs. The best understood atopic disease in horses is insect hypersensitivity, but the goal of effective treatment with allergen-specific immunotherapy remains elusive. In this review, updates in pathogenesis of allergic states and a brief mention of the new data on what is known in humans and dogs and how that relates to equine allergic disorders are discussed.

    Abstract There is considerable interest in the immunobiological processes through which the development of allergic sensitization to chemicals is initiated and orchestrated. One of the most intriguing issues is the basis for the elicitation by chemical sensitizers of different forms of allergic...... reaction; that is, allergic contact dermatitis or sensitization of the respiratory tract associated with occupational asthma. Studies in rodents have revealed that differential forms of allergic sensitization to chemicals are, in large part at least, a function of the selective development of discrete...... functional sub-populations of CD4(+) and CD8(+) T-lymphocytes. Evidence for a similar association of chemical allergy in humans with discrete T-lymphocyte populations is, however, limited. It is of some interest, therefore, that two recent articles from different teams of investigators have shed new light...

    Full Text Available The application of food-specific IgG antibody detection in allergy dermatoses was explored. 181 patients with allergy dermatoses were diagnosed from January to September 2014 and 20 healthy subjects were selected. Fourteen kinds of food-specific IgG antibodies were detected by ELISA method among all the subjects. The positive rates of IgG antibody of the patient group and the healthy group were respectively 65.2% and 5.0%. The positive rates of IgG antibody of egg, milk, shrimp and crab took a large proportion in three groups of patients with three kinds of allergy dermatoses of urticaria, eczema and allergic dermatitis, the proportion of which was respectively 70.2%, 77.8% and 71.7%. Among urticaria and allergic dermatitis patients with positive antibody, the positive rate of children was significantly higher than that of adults (p0.05. Allergy dermatoses are closely related to food-specific IgG antibodies, and the allergy dermatoses patients have a high incidence rate of food intolerance; detecting IgG antibody in the serum of patients is of great significance for the diagnosis and treatment of allergy dermatoses.

    Full Text Available Abstract Background Cow's milk allergy is one of the most common food allergies among younger children. We investigated IgE antibodies to milk, and IgE and IgG4 antibodies to casein, α-lactalbumin and β-lactoglobulin in cow's milk allergic (CMA and non-allergic (non-CMA children in order to study their clinical usefulness. Methods Eighty-three children with suspected milk allergy (median age: 3.5 years, range: 0.8-15.8 years were diagnosed as CMA (n = 61 or non-CMA (n = 22 based on an open milk challenge or convincing clinical history. Their serum concentrations of allergen-specific (s IgE and IgG4 antibodies were measured using ImmunoCAP®. For the sIgG4 analysis, 28 atopic and 31 non-atopic control children were additionally included (all non-milk sensitized. Results The CMA group had significantly higher levels of milk-, casein- and β-lactoglobulin-sIgE antibodies as compared to the non-CMA group. The casein test showed the best discriminating performance with a clinical decision point of 6.6 kUA/L corresponding to 100% specificity. All but one of the CMA children aged > 5 years had casein-sIgE levels > 6.6 kUA/L. The non-CMA group had significantly higher sIgG4 levels against all three milk allergens compared to the CMA group. This was most pronounced for casein-sIgG4 in non-CMA children without history of previous milk allergy. These children had significantly higher casein-sIgG4 levels compared to any other group, including the non-milk sensitized control children. Conclusions High levels of casein-sIgE antibodies are strongly associated with milk allergy in children and might be associated with prolonged allergy. Elevated casein-sIgG4 levels in milk-sensitized individuals on normal diet indicate a modified Th2 response. However, the protective role of IgG4 antibodies in milk allergy is unclear.

Pediatr Allergy Immunol 2010: 21: e450–e453. © 2009 John Wiley & Sons A/S A renewed interest in oral desensitization as treatment for food allergy has been observed in the last few years. We studied a novel method based on the end point skin prick test procedure to establish the starting dose for oral desensitization in a group of 30 children higly allergic to milk. The results (in terms of reactions to the first dose administered) were compared with a group of 20 children allergic to milk as well. Such control group started to swallow the same dose of 0.015 mg/ml of milk. None reacted to the first dose when administered according to the end point skin prick test. On the other side, ten out of 20 children (50%) from the control group showed mild allergic reactions to the first dose of milk. In conclusion the end point skin prick test procedure results safe and easy to be performed in each single child in order to find out the starting dose for oral desensitization to milk, also by taking into account the individual variability.

    2018-05-03

    Insects represent an alternative for meat and fish in satisfying the increasing demand for sustainable sources of nutrition. Approximately two billion people globally consume insects. They are particularly popular in Asia, Latin America, and Africa. Most research on insect allergy has focussed on occupational or inhalation allergy. Research on insect food safety, including allergenicity, is therefore of great importance. The objective of this review is to provide an overview of cases reporting allergy following insect ingestion, studies on food allergy to insects, proteins involved in insect allergy including cross-reactive proteins, and the possibility to alter the allergenic potential of insects by food processing and digestion. Food allergy to insects has been described for silkworm, mealworm, caterpillars, Bruchus lentis, sago worm, locust, grasshopper, cicada, bee, Clanis bilineata, and the food additive carmine, which is derived from female Dactylopius coccus insects. For cockroaches, which are also edible insects, only studies on inhalation allergy have been described. Various insect allergens have been identified including tropomyosin and arginine kinase, which are both pan-allergens known for their cross-reactivity with homologous proteins in crustaceans and house dust mite. Cross-reactivity and/or co-sensitization of insect tropomyosin and arginine kinase has been demonstrated in house dust mite and seafood (e.g. prawn, shrimp) allergic patients. In addition, many other (allergenic) species (various non-edible insects, arachnids, mites, seafoods, mammals, nematoda, trematoda, plants, and fungi) have been identified with sequence alignment analysis to show potential cross-reactivity with allergens of edible insects. It was also shown that thermal processing and digestion did not eliminate insect protein allergenicity. Although purified natural allergens are scarce and yields are low, recombinant allergens from cockroach, silkworm, and Indian mealmoth are

    The authors report current information on allergy to aromatic agents present in cosmetics and products of household chemistry. In the perfume industry, about 3000 aromas are used. Single products may contain from 10 to 300 compounds. The problem of difficulties encountered in the diagnosis of hypersensitivity to odors is addressed. The mixture of 8 such products used in diagnostic screening is able to detect allergy only in about 30% of patients who do not tolerate cosmetics. Changing frequency of allergy to individual aromas is discussed. It has been now observed that cinnamon products are less allergic than chemical compounds present in oak moss. Since the 1990s of the last century, allergy to a synthetic aromatic agent, Lyral is the subject of interest in many research centers involved in studies of contact allergy. Half the cosmetics present in European markets, especially deodorants, after shave cosmetics, hand and body lotions contain this agent. It induces positive reactions in about 10% of patients allergic to aromatic agents. Detection of allergy to Lyral is difficult as it is not included in the set of commercial allergens used to diagnose hypersensitivity to aromatic agents.

    Food allergy represents a health problem worldwide and leads to life-threatening reactions and even impairs quality of life. Epidemiological data during the past decades is very heterogeneous because of the use of different diagnostic procedures, and most studies have only been performed in specific geographical areas. The aim of this article is to review the available data on the geographical distribution of food allergies at the food source and molecular level and to link food allergy patterns to the aeroallergen influence in each area. Systematic reviews, meta-analysis, studies performed within the EuroPrevall Project and EAACI position papers regarding food allergy were analysed. The prevalence of food allergy sensitization differs between geographical areas, probably as a consequence of differences among populations, their habits and the influence of the cross-reactivity of aeroallergens and other sources of allergens. Geographical differences in food allergy are clearly evident at the allergenic molecular level, which seems to be directly influenced by the aeroallergens of each region and associated with specific clinical patterns.

    Numerous genes are involved in innate and adaptive immunity and these have been modified over millions of years. During this evolution, the mucosal immune system has developed two anti-inflammatory strategies: immune exclusion by the use of secretory antibodies to control epithelial colonization of microorganisms and to inhibit the penetration of potentially harmful agents; and immunosuppression to counteract local and peripheral hypersensitivity against innocuous antigens, such as food proteins. The latter strategy is called oral tolerance when induced via the gut. Homeostatic mechanisms also dampen immune responses to commensal bacteria. The mucosal epithelial barrier and immunoregulatory network are poorly developed in newborns. The perinatal period is, therefore, critical with regard to the induction of food allergy. The development of immune homeostasis depends on windows of opportunity during which innate and adaptive immunity are coordinated by antigen-presenting cells. The function of these cells is not only orchestrated by microbial products but also by dietary constituents, including vitamin A and lipids, such as polyunsaturated omega-3 fatty acids. These factors may in various ways exert beneficial effects on the immunophenotype of the infant. The same is true for breast milk, which provides immune-inducing factors and secretory immunoglobulin A, which reinforces the gut epithelial barrier. It is not easy to dissect the immunoregulatory network and identify variables that lead to food allergy. This Review discusses efforts to this end and outlines the scientific basis for future food allergy prevention.

A PubMed search was performed using the keywords India and food allergy, Asia and food allergy, and South Asia and food allergy for any period. Articles cited in selected studies were reviewed for their appropriateness of inclusion into this review. Publications were included that were original research and fit the topic of food allergy and South Asia. South Asia is defined as region inclusive of India, Pakistan, Bangladesh, and Sri Lanka. A total of 169 articles were initially identified, and 47 were reviewed in detail for inclusion in this review. The primary focus was placed on 10 studies that consisted of case reports of newly reported or documented food allergy, survey studies that investigated food allergy prevalence in specific demographics, and prospective and cross-sectional studies with case controls, all of which investigated food allergy prevalence by allergy testing in a selected population. The medical literature on the prevalence and types of food allergy in South Asia indicates that there is a variety of unusual and unique allergens and an overall low incidence of food allergy. There is also an association of increased food allergy prevalence in individuals who live in metropolitan regions or who migrate to communities that have adopted westernization.

    IgE-associated food allergy affects approximately 3% of the population and has severe effects on the daily life of patients—manifestations occur not only in the gastrointestinal tract but also affect other organ systems. Birth cohort studies have shown that allergic sensitization to food allergens develops early in childhood. Mechanisms of pathogenesis include cross-linking of mast cell– and basophil-bound IgE and immediate release of inflammatory mediators, as well as late-phase and chronic allergic inflammation, resulting from T-cell, basophil, and eosinophil activation. Researchers have begun to characterize the molecular features of food allergens and have developed chip-based assays for multiple allergens. These have provided information about cross-reactivity among different sources of food allergens, identified disease-causing food allergens, and helped us to estimate the severity and types of allergic reactions in patients. Importantly, learning about the structure of disease-causing food allergens has allowed researchers to engineer synthetic and recombinant vaccines. PMID:25680669

    2018-02-21

    Background Chemically modified allergen extracts, known as allergoids, are commonly used for treating allergic patients. In general terms, the concept of allergoids implies allergen extracts with a reduction of their allergenicity maintaining their immunogenicity. Different methods to obtain allergoids have been developed in the past years, opening attractive lines of research. Objective To review the different approaches to allergoid development as well as their characterization, mechanism of action and efficacy and safety issues. Methods A revision and analysis of the different types of allergoids has been performed, with special attention to patents submitted and granted in the last years. Additionally, updated information about the mechanism of action and clinical evidence and safety of allergoids has been discussed. Results Principally, allergoids are obtained by the polymerization of native allergen extracts with aldehydes, including formaldehyde or glutaraldehyde. However, recent patents and publications about different chemical modifications have been presented, as well as about the use of new adjuvants with allergoids. Regarding the characterization, allergoids require more sophisticated analytical methods than native extracts, as a consequence of their properties and characteristics. Conclusion In the last years, the partial understanding of the mechanism of action and the generation of clinical evidence of different types of allergoids, linked to their excellent safety profile and their convenience for a quick build up phase, have made of allergoids an excellent product for allergy treatment.

    2010-08-01

    Anaphylaxis is an acute-onset and potentially life-threatening allergic reaction that can be caused by numerous allergic triggers including stinging insects. This review focuses on recent advances, natural history, risk factors and therapeutic considerations. Recent work suggests that concerns over insect allergy diagnosis continue to exist. This is especially true with individuals who have a convincing history of a serious life-threatening anaphylactic event, but lack the necessary diagnostic criteria of venom-specific IgE by skin test or in-vitro diagnostic methods to confirm the diagnosis. The role of occult mastocytosis or increased basophile reactivity may play a role in this subset population. Additionally, epinephrine continues to be underutilized as the primary acute intervention for an anaphylactic reaction in the emergent setting. The incidence of anaphylaxis continues to rise across all demographic groups, especially those less than 20 years of age. Fortunately, the fatalities related to anaphylaxis appear to have decreased over the past decades. Our understanding of various triggers, associated risk factors, as well as an improved understanding and utilization of biological markers such as serum tryptase have improved. Our ability to treat insect anaphylaxis by venom immunotherapy is highly effective. Unfortunately, anaphylaxis continues to be underappreciated and undertreated especially in regard to insect sting anaphylaxis. This includes the appropriate use of injectable epinephrine as the primary acute management tool. These findings suggest that continued education of the general population, primary care healthcare providers and emergency departments is required.

    2000-08-01

    Furry animals produce allergens that can cause allergic rhinitis and asthma. In contrast, scaly animals, such as lizards, are assumed not to be allergenic. We sought to evaluate a 32-year-old man who complained of allergic rhinitis and asthma symptoms that occurred exclusively in his own home. He had dogs and cats at home but denied any increase in symptoms specifically associated with these pets. Skin prick testing initially performed to 42 common aeroallergens, including cat, dog, and house dust mite, elicited negative results. He later reported that the symptoms were worse on exposure to his pet iguanas. Skin prick tests were subsequently performed to an extract made from scales from his pet iguana. Extracts were also prepared from several zoo reptiles. Immunoassays for IgE antibody, as well as IgE immunoblots, were performed by using these extracts and the patient's serum. The skin prick test result with the pet iguana scale extract was positive. The patient's serum contained IgE antibody to his own pet iguana and to a zoo iguana. Our patient's history, skin test results, and in vitro studies clearly demonstrate that he is allergic to iguana. Physicians should be aware that such allergy to scaly pets may occur and should not restrict history taking to questions about furry pets.

  14. Diet in 1-year-old farm and control children and allergy development: results from the FARMFLORA birth cohort

    2016-08-01

    Full Text Available Background: A farming environment confers strong protection against allergy development. We have previously shown that farming mothers consume more full-fat dairy than control mothers, who instead consume more low-fat dairy, margarine, and oils; margarine and oil intake was associated with increased risk of allergy development in their children. Objectives: The aims of this study were to investigate the differences in diet between children in farming and control families at 1 year of age, to investigate the relation between the diets of the mothers and their children, and to relate the children's diet to allergy development. Design: The diet of 1-year-old children from dairy farming families (n=28 and from control families in the same rural area (n=37 was assessed by 24-h dietary recalls, followed by 24-h food diaries. Allergy was diagnosed by pediatricians at 3 years of age using strict predefined criteria. Results: Farm children had a higher intake of farm milk, whole cream, cholesterol, saturated fat, and fat in total and tended to eat more butter, while controls consumed more carbohydrates and poultry and tended to eat more margarine. Farm children also had higher intakes of homemade porridge/gruel, oily fish, and iodine. The intake of butter and whole milk in children and mothers correlated significantly in farm families but not in controls. A weak negative association was found between seafood intake and allergy development, while allergy was positively associated with the intake of pork as well as zinc in the control group; these intakes also correlated with each other. Conclusions: Consistent with mothers in farming families, the children consumed more full-fat dairy and saturated fat than did controls, but this could not be linked to the low risk of allergy in the farming group. Seafood intake might protect against allergy development, in accordance with earlier findings.

  15. A shorter and more specific oral sensitization-based experimental model of food allergy in mice.

    Cow's milk protein allergy (CMPA) is one of the most prevalent human food-borne allergies, particularly in children. Experimental animal models have become critical tools with which to perform research on new therapeutic approaches and on the molecular mechanisms involved. However, oral food allergen sensitization in mice requires several weeks and is usually associated with unspecific immune responses. To overcome these inconveniences, we have developed a new food allergy model that takes only two weeks while retaining the main characters of allergic response to food antigens. The new model is characterized by oral sensitization of weaned Balb/c mice with 5 doses of purified cow's milk protein (CMP) plus cholera toxin (CT) for only two weeks and posterior challenge with an intraperitoneal administration of the allergen at the end of the sensitization period. In parallel, we studied a conventional protocol that lasts for seven weeks, and also the non-specific effects exerted by CT in both protocols. The shorter protocol achieves a similar clinical score as the original food allergy model without macroscopically affecting gut morphology or physiology. Moreover, the shorter protocol caused an increased IL-4 production and a more selective antigen-specific IgG1 response. Finally, the extended CT administration during the sensitization period of the conventional protocol is responsible for the exacerbated immune response observed in that model. Therefore, the new model presented here allows a reduction not only in experimental time but also in the number of animals required per experiment while maintaining the features of conventional allergy models. We propose that the new protocol reported will contribute to advancing allergy research. Copyright © 2012 Elsevier B.V. All rights reserved.

    Portnoy, Jay M; Shroba, Jodi

    2014-10-01

    Food allergies are estimated to affect as many as 8 % of children with 2.5 % being allergic to peanut products. Based on the results of recent surveys, this prevalence has been increasing over the last few decades for unknown reasons. As children with food allergies reach school age, the issue is becoming more common in schools. For that reason, schools are now required to be prepared to take responsibility for the safety of food-allergic students. This review discusses the common problems surrounding management of food allergies in the school setting along with reasonable recommendations for addressing those problems. The most important component of food allergy management is for the student to get an accurate diagnosis and to then discuss development of an anaphylaxis action plan with their health-care provider. Each school should insist that a copy of such a plan be provided for each student with food allergy and that epinephrine is readily available should a student have an anaphylactic reaction. In addition to epinephrine, it is essential that school personnel be properly trained to recognize and treat allergic reactions should they occur. Known deficiencies in school preparedness have been documented in previous literature, and consequently, both state and the federal government have begun to implement policies to help with school preparedness.

  6. Ocular allergy latin american consensus

    2011-12-01

    Full Text Available PURPOSE: To establish current definition, classification and staging, and to develop diagnosis and treatment recommendations for ocular allergy, by using Delphi approach. METHODS: Ten Latin American experts on ocular allergy participated in a 4-round Delphi panel approach. Four surveys were constructed and answered by panelists. A two-thirds majority was defined as consensus. Definition, classification, staging and diagnosis and treatment recommendations were the main outcomes. RESULTS: "Ocular allergy" was proposed as the general term to describe ocular allergic diseases. Consensus regarding classification was not reached. Signs and symptoms were considered extremely important for the diagnosis. It was consensus that a staging system should be proposed based on the disease severity. Environmental control, avoidance of allergens and the use of artificial tears were recommended as first line treatment. The secondary treatment should include topical anti-histamines, mast cell stabilizers and multi actions drugs. Topical non-steroidal anti-inflammatory and vasoconstrictors were not recommended. Topical corticosteroids were recommended as third line of treatment for the most severe keratoconjunctivitis. Consensus was not reached regarding the use of systemic corticosteroids or immunosuppressant. Surgical approach and unconventional treatments were not recommended as routine. CONCLUSION: The task of creating guidelines for ocular allergies showed to be very complex. Many controversial topics remain unsolved. A larger consensus including experts from different groups around the world may be needed to further improve the current recommendations for several aspects of ocular allergy.

    Anaphylaxis to teicoplanin appears to be extremely rare, with only one confirmed case report worldwide. Two anaesthetic allergy clinics in the UK have received a number of suspected cases referred for investigation, and we present here the first case series of teicoplanin allergy. We investigated 20 cases of suspected teicoplanin allergy, identified from the two clinics over a period of two years. We devised a set of five criteria to categorize the certainty of their diagnosis. These included: (1) reaction within 15 min of administration of teicoplanin, (2) ≥2 features of anaphylaxis present, (3) positive skin testing or challenge testing, (4) raised serum mast cell tryptase (MCT), (5) alternative diagnosis excluded. Based on these criteria we defined the likelihood of IgE-mediated allergy to teicoplanin as: definite-met all criteria; probable-met criteria 1.2 and 5, plus 3 or 4; uncertain-met criteria 1.2 and 5; excluded- any others. We identified 7 'definite', 7 'probable' and 2 'uncertain' cases of teicoplanin allergy. Four cases were excluded. IgE-mediated anaphylaxis to teicoplanin appears to be more common than previously thought. This is true even if only definitive cases are considered. Investigation of teicoplanin allergy is hampered by the lack of standardized skin test concentrations. In some cases, there was a severe clinical reaction, but without any skin test evidence of histamine release. The mechanism of reaction in these cases is not known and requires further study. © The Author 2015. Published by Oxford University Press on behalf of the British Journal of Anaesthesia.

    Currently, there is no mandatory labelling of allergens for non-pre-packed foods in the EU. Therefore, consumers with food allergy rely on voluntary information provided by the staff. The aim of this study was to characterize allergic reactions to non-pre-packed foods and to investigate whether staff in bakery shops were able to give advice regarding a safe product choice. Questionnaires were sent to 200 parents of children with a food allergy. Staff of 50 bakery shops were interviewed regarding selling non-pre-packed foods to food-allergic customers. Bakery products being recommended as 'cow's milk-free' were bought, and cow's milk protein levels were measured using ELISA. A total of 104 of 200 questionnaires were returned. 25% of the children experienced an allergic reaction due to a non-pre-packed food from bakery shops and 20% from ice cream parlours. Sixty percent of the bakery staff reported serving food-allergic customers at least once a month, 24% once a week. Eighty four percent of the staff felt able to advise food-allergic consumers regarding a safe product choice. Seventy three 'cow's milk-free' products were sold in 44 bakery shops. Cow's milk could be detected in 43% of the bakery products, 21% contained >3 mg cow's milk protein per serving. Staff in bakery shops felt confident about advising customers with food allergy. However, cow's milk was detectable in almost half of bakery products being sold as 'cow's milk-free'. Every fifth product contained quantities of cow's milk exceeding an amount where approximately 10% of cow's milk-allergic children will show clinical relevant symptoms. © 2015 John Wiley & Sons A/S.

    2010-02-01

    Airborne allergens are the major cause of allergic rhinitis and asthma. Daily exposure comes from indoor sources, chiefly at home but occasionally at schools or offices. Seasonal exposure to outdoor allergens, pollens, and molds is another important source. Exposure to unusual substances at work causes occupational asthma, accounting for about 5% of asthma in adults. Indoor and outdoor air pollutants trigger airway inflammation and increase the severity of asthma. Diesel exhaust particles increase the production of IgE antibodies. Identification and reduction of exposure to allergens is a very important part of the management of respiratory allergic diseases. The first section of this chapter discusses domestic allergens, arthropods (mites and cockroaches), molds, and mammals (pets and mice). Indoor humidity and water damage are important factors in the production of mite and mold allergens, and discarded human food items are important sources of proliferation of cockroaches and mice. Means of identifying and reducing exposure are presented. The second section discusses outdoor allergens: pollens and molds. The particular plants or molds and the amount of exposure to these allergens is determined by the local climate, and local pollen and mold counts are available to determine the time and amount of exposure. Climate change is already having an important effect on the distribution and amount of outdoor allergens. The third section discusses indoor and outdoor air pollution and methods that individuals can take to reduce indoor pollution in addition to eliminating cigarette smoking. The fourth section discusses the diagnosis and management of occupational asthma. Copyright 2010 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc. All rights reserved.

Beyond this high risk group iodine deficiency is not considered to be a significant problem. This case report describes a 12-year-old male with severe iodine deficiency disorder (IDD resulting from restricted dietary intake due to multiple food allergies. We describe iodine replacement for this patient and continued monitoring for iodine sufficiency. Children with multiple food allergies, in particular those with restrictions to iodized salt and seafood, should be considered high risk for severe iodine deficiency.

To determine whether the consumption of peanuts during pregnancy and breastfeeding is a risk factor for peanut allergy in infants. We enrolled 403 infants in a case-control study. The cases were infants aged 18 months or less with a diagnosis of peanut allergy based on a history of clinical reaction after exposure to peanuts and the presence of peanut-specific immunoglobulin E. Controls were age-matched infants with no known clinical history or signs of atopic disease. The mothers of the children filled out a detailed questionnaire about maternal diet during pregnancy and breastfeeding, the infant's diet, the presence of peanut products in the infant's environment, and family history of atopy. The mean (SD) age of cases was 1.23 (0.03) years. The groups were comparable in terms of the rate and duration of breastfeeding. However, the reported consumption of peanuts during pregnancy and breastfeeding was higher in the case group and associated with an increased risk of peanut allergy in offspring (odds ratio [OR], 4.22 [95% confidence interval [CI], 1.57-11.30 and OR, 2.28 [95% CI, 1.31-3.97] for pregnancy and breastfeeding, respectively). Overall, the infants with peanut allergy did not seem to be more exposed to peanut products in their environment than the controls. Early exposure to peanut allergens, whether in utero or through human breast milk, seems to increase the risk of developing peanut allergy.

    Atopy patch test has been recognized as a diagnostic tool for the verification of food allergies in infants and small children suffering from atopic dermatitis. The test also has a role in the diagnosis of food allergies characterized by clinical signs associated with the digestive system. Yet, in spite of numerous studies, the test itself has hitherto not been standardized. Our study enlisted 151 children less than two years of age, who exhibited suspect skin and/or gastrointestinal manifestations of food allergy to cow's milk, and in whom tests failed to prove early type of allergic reaction. Atopy patch test was positive in 28% of the children with atopic dermatitis, 43% of the children with suspect gastrointestinal manifestation and 32% of the children with skin and gastrointestinal manifestations of food allergy. In our experience, atopy patch test is an excellent addition to the hitherto used tests for the diagnosis of food allergies. It targets specifically delayed type hypersensitivity reactions, which are difficult to confirm with other diagnostic tools. It is furthermore simple to perform, noninvasive and produces a minimum of undesired side effects. For these reasons, it should become part of the routine diagnostic toolset for food allergies to cow's milk in infants and children, and applied before a food challenge test.

    Inappropriate test methods are increasingly utilized to diagnose allergy. They fall into two categories: I. Tests with obscure theoretical basis, missing validity and lacking reproducibility, such as bioresonance, electroacupuncture, applied kinesiology and the ALCAT-test. These methods lack both the technical and clinical validation needed to justify their use. II. Tests with real data, but misleading interpretation: Detection of IgG or IgG4-antibodies or lymphocyte proliferation tests to foods do not allow to separate healthy from diseased subjects, neither in case of food intolerance, allergy or other diagnoses. The absence of diagnostic specificity induces many false positive findings in healthy subjects. As a result unjustified diets might limit quality of life and lead to malnutrition. Proliferation of lymphocytes in response to foods can show elevated rates in patients with allergies. These values do not allow individual diagnosis of hypersensitivity due to their broad variation. Successful internet marketing, infiltration of academic programs and superficial reporting by the media promote the popularity of unqualified diagnostic tests; also in allergy. Therefore, critical observation and quick analysis of and clear comments to unqualified methods by the scientific medical societies are more important than ever.

    Full Text Available The increasing use of natural rubber latex medical gloves in the last three decades has caused an increase in latex allergy. The majority of risk groups for allergy development include health care workers, workers in the rubber industry, atopic individuals and children with congenital malformations. Three types of pathological reactions can occur in people using latex medical gloves: irritant contact dermatitis, allergic contact dermatitis and immediate hypersensitivity. The latex allergy is caused by constituent components of latex gloves and added powders; there are also numerous latex allergens involved in cross-reactivity between latex and fruits and vegetables, the so-called latex-fruit syndrome. The diagnosis is based on an accurate history of exposure, clinical presentation and confirmatory in vivo and in vitro tests. Prevention is the easiest, most effective and least expensive way to avoid latex allergy. Powder-free latex gloves with reduced levels of proteins and chemicals, and synthetic gloves for allergic workers must be provided in the work environment. There are already many health care institutions around the world where all latex products have been replaced by synthetic material products.

    2011-03-18

    Tattoos with henna colours have become very popular and the prevalence of contact allergy seems to increase. This is a short review article based on our own clinical experience and literature identified through a search in PubMed with the words "henna", "paraphenylendiamin" and "allergic contact dermatitis." A case report is included. It is well documented that many experience skin reactions after henna tattoos. The cause is almost always contact allergy to the azo compound paraphenylendiamin, which is added to speed up the process and make the colour darker. Most people, including children, get henna tattoos during vacations in Asia or the Mediterranean. Established contact allergy is permanent. Many hair-colour products contain paraphenylendiamin, and persons with contact allergy against the product may develop a very strong contact allergic eczema by use of such substances. Acute reactions are treated with local cortisone products, or with systemic steroids. Cross reaction to substances with a similar chemical structure may occur. Tattoos with paraphenylendiamin-containing henna colours should be avoided.

    Five years have passed since the Japanese Pediatric Guideline for Food Allergy (JPGFA) was first revised in 2011 from its original version. As many scientific papers related to food allergy have been published during the last 5 years, the second major revision of the JPGFA was carried out in 2016. In this guideline, food allergies are generally classified into four clinical types: (1) neonatal and infantile gastrointestinal allergy, (2) infantile atopic dermatitis associated with food allergy, (3) immediate-type of food allergy (urticaria, anaphylaxis, etc.), and (4) special forms of immediate-type of food allergy such as food-dependent exercise-induced anaphylaxis and oral allergy syndrome (OAS). Much of this guideline covers the immediate-type of food allergy that is seen during childhood to adolescence. Infantile atopic dermatitis associated with food allergy type is especially important as the onset of most food allergies occurs during infancy. We have discussed the neonatal and infantile gastrointestinal allergy and special forms of immediate type food allergy types separately. Diagnostic procedures are highlighted, such as probability curves and component-resolved diagnosis, including the recent advancement utilizing antigen-specific IgE. The oral food challenge using a stepwise approach is recommended to avoid complete elimination of causative foods. Although oral immunotherapy (OIT) has not been approved as a routine treatment by nationwide insurance, we included a chapter for OIT, focusing on efficacy and problems. Prevention of food allergy is currently the focus of interest, and many changes were made based on recent evidence. Finally, the contraindication between adrenaline and antipsychotic drugs in Japan was discussed among related medical societies, and we reached an agreement that the use of adrenaline can be allowed based on the physician's discretion. In conclusion, this guideline encourages physicians to follow the principle to let patients

    While less than 1% of the general population is sensitized to latex, the U.S. Occupational Safety and Health Administration estimates that 8-12% of health-care workers are sensitized. The major source of workplace exposure is powdered natural rubber latex (NRL) gloves. NRL is harvested from HEVEA: brasiliensis trees and ammoniated to prevent coagulation resulting in the hydrolysis of the latex proteins. Prior to use in manufacturing, the latex is formulated by the addition of multiple chemicals. Thus, human exposure is to a mixture of residual chemicals and hydrolyzed latex peptides. Clinical manifestations include irritant contact dermatitis, allergic contact dermatitis (type IV), and type I immediate hypersensitivity response. Type I (IgE-mediated) NRL allergy includes contact urticaria, systemic urticaria, angioedema, rhinitis, conjunctivitis, bronchospasm, and anaphylaxis. Taking an accurate history, including questions on atopic status, food allergy, and possible reactions to latex devices makes diagnosis of type-I latex allergy possible. To confirm a diagnosis, either in vivo skin prick testing (SPT) or in vitro assays for latex-specific IgE are performed. While the SPT is regarded as a primary confirmatory test for IgE-mediated disease, the absence of a U.S. Food and Drug Administration-licensed HEVEA: brasiliensis latex extract has restricted its use in diagnosis. Serological tests have, therefore, become critically important as alternative diagnostic tests. Three manufacturers currently have FDA clearance for in vitro tests, to detect NRL-specific IgE. The commercially available assays may disagree on the antibody status of an individual serum, which may be due to the assay's detecting anti-NRL IgEs to different allergenic NRL proteins. Sensitized individuals produce specific IgE antibody to at least 10 potent HEVEA: allergens, Hev b 1-Hev b 10, each of which differs in its structure, size, and net charge. The relative content and ratios of Hevs in the

  17. Milk consumption does not lead to mucus production or occurrence of asthma.

    2005-12-01

    There is a belief among some members of the public that the consumption of milk and dairy products increases the production of mucus in the respiratory system. Therefore, some who believe in this effect renounce drinking milk. According to Australian studies, subjects perceived some parameters of mucus production to change after consumption of milk and soy-based beverages, but these effects were not specific to cows' milk because the soy-based milk drink with similar sensory characteristics produced the same changes. In individuals inoculated with the common cold virus, milk intake was not associated with increased nasal secretions, symptoms of cough, nose symptoms or congestion. Nevertheless, individuals who believe in the mucus and milk theory report more respiratory symptoms after drinking milk. In some types of alternative medicine, people with bronchial asthma, a chronic inflammatory disease of the lower respiratory tract, are advised not to eat so-called mucus-forming foods, especially all kinds of dairy products. According to different investigations the consumption of milk does not seem to exacerbate the symptoms of asthma and a relationship between milk consumption and the occurrence of asthma cannot be established. However, there are a few cases documented in which people with a cow's milk allergy presented with asthma-like symptoms.

    During the last decades, the world has witnessed a dramatic increase in allergy prevalence. Epidemiological evidence shows that growing up on a farm is a protective factor, which is partly explained by the consumption of raw cow’s milk. Indeed, recent studies show inverse associations between raw cow’s milk consumption in early life and asthma, hay fever, and rhinitis. A similar association of raw cow’s milk consumption with respiratory tract infections is recently found. In line with these f...

    Health literacy among caregivers of food allergic individuals (FAIs) is poorly described, as are the information sources sought regarding food allergy. To assess the association among health literacy, trust in online sources of information, and food allergy quality of life (QoL) and self-efficacy. An online survey was administered to caregivers of FAIs assessing health literacy (Newest Vital Sign [NVS] and the eHeals Internet health literacy index), trust in online information (Hargittai Internet credibility index and Annenberg National Health Communication Survey [ANHCS]), QoL (Food Allergy Quality of Life Parental Burden), and self-efficacy (Food Allergy Self-Efficacy Questionnaire [FASEQ]). Among 1562 respondents, 94.6% (NVS) and 61.1% (eHeals) had good health literacy, and 58% had high levels of trust in online information (both indexes). The NVS correlated poorly with the eHeals and Hargittai indexes. Hargittai and eHeals scores were moderately correlated (r = 0.37, P information (both indexes), worsening FASEQ score, blog readership, advocacy group membership, caring for multiple FAIs, and having milk or egg allergy were associated with worse FAQL-PB scores. In this sample, health literacy and trust in online information sources were high, with high trust in online information sources negatively associated with QoL. Advocacy group membership had an independent negative association with QoL. Copyright © 2016 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.

    The development of food allergies is increasingly being recognized as a post-solid organ transplant complication. In this article, we review the spectrum of post-transplant food allergy development and the proposed mechanisms for de novo food allergies and the clinical significance they pose. The development of new food allergies is disproportionately associated with pediatric liver transplants, where it occurs in up to 38% of select populations. The mechanism of food allergy development is not completely understood; however, it is likely promoted by unbalanced immune suppression. De novo food allergy development is a common complication of solid organ transplants with the highest risk occurring in pediatric liver transplant recipients. There are likely multiple mechanisms for food allergy development including passive transfer of membrane-bound IgE and lymphocytes from donor to recipient, as well as loss of food tolerance and active development of new food allergies. The optimal management of food allergies following organ transplants has not been well researched but may include changing the immune suppression regimen if the food allergy does not resolve without intervention.

    Full Text Available Background: Diagnosis of food allergy is difficult in children. Food allergies are diagnosed using several methods that include medical histories, clinical examinations, skin prick and serum-specific immunoglobulin E (IgE tests, radio-allergosorbent test (RAST, food challenge, and supervised elimination diets. In this study we evaluated allergies to cow's milk, egg, peanut, and fish in children with suspected food allergies with skin prick tests and serum and feces RAST. Methods: Forty-one children with clinical symptoms of food allergies were enrolled in the study. Skin prick tests and serum and fecal RAST were performed and compared with challenge tests. Results: The most common sites of food allergy symptoms were gastrointestinal (82.9% and skin (48.8%. 100% of the patients responded to the challenge tests with cow’s milk, egg, peanut, and fish. 65% of the patients tested positive with the skin prick test, 12.1% tested positive with serum RAST, and 29.2% tested positive with fecal RAST. Conclusions: The skin prick test was more sensitive than serum or fecal RAST, and fecal RAST was more than twice as sensitive as serum RAST.

    The aim of this paper was to study the relationship between milk flow emission variables recorded during milking of dairy goats with variables related to milking routine, goat physiology, milking parameters and milking machine characteristics, to determine the variables affecting milking performance and help the goat industry pinpoint farm and milking practices that improve milking performance. In total, 19 farms were visited once during the evening milking. Milking parameters (vacuum level (VL), pulsation ratio and pulsation rate, vacuum drop), milk emission flow variables (milking time, milk yield, maximum milk flow (MMF), average milk flow (AVMF), time until 500 g/min milk flow is established (TS500)), doe characteristics of 8 to 10 goats/farm (breed, days in milk and parity), milking practices (overmilking, overstripping, pre-lag time) and milking machine characteristics (line height, presence of claw) were recorded on every farm. The relationships between recorded variables and farm were analysed by a one-way ANOVA analysis. The relationships of milk yield, MMF, milking time and TS500 with goat physiology, milking routine, milking parameters and milking machine design were analysed using a linear mixed model, considering the farm as the random effect. Farm was significant (Pfarms, being similar to those recommended in scientific studies. Few milking parameters and milking machine characteristics affected the tested variables: average vacuum level only showed tendency on MMF, and milk pipeline height on TS500. Milk yield (MY) was mainly affected by parity, as the interaction of days in milk with parity was also significant. Milking time was mainly affected by milk yield and breed. Also significant were parity, the interaction of days in milk with parity and overstripping, whereas overmilking showed a slight tendency. We concluded that most of the studied variables were mainly related to goat physiology characteristics, as the effects of milking parameters and

    To determine the most frequent food allergens causing immediate hypersensitivity reactions in Swiss children of different age groups and to investigate the clinical manifestation of IgE-mediated food allergies in young patients. The study was a prospective analysis of children referred for assessment of immediate type I food hypersensitivity reactions. The diagnostic strategy included a careful history, skin prick tests with commercial extracts and native foods, in vitro determination of specific IgE to food proteins and food challenges when appropriate. A total of 278 food allergies were identified in 151 children with a median age of 1.9 years at diagnosis. Overall, the most frequent food allergens were hen's egg (23.7%), cow's milk (20.1%), peanut (14.0%), hazelnut (10.4%), wheat (6.1%), fish (4.3%), kiwi and soy (2.2% each). In infancy, cow's milk, hen's egg and wheat were the most common allergens. In the second and third year of life however, the top three food allergens were hen's egg, cow's milk and peanut, whereas above the age of 3 years, peanut was number one, followed by hen's egg and fish. Overall, urticaria (59.0%) and angioedema (30.2%) were the most frequent clinical manifestations. Gastrointestinal symptoms were found in 25.9% and respiratory involvement in 25.2%. There were 13 cases (4.7%) of anaphylaxis to peanut, fish, cow's milk, hen's egg, wheat and shrimps. A total of eight allergens account for 83% of IgE-mediated food allergies in Swiss infants and children, with differences in the distribution and order of the most frequently involved food allergens between paediatric age groups.

    Fish is one of the main elicitors for food allergies. For a long time, the clinical picture of fish allergy was reduced to the following features. First, fish-allergic patients suffer from a high IgE cross-reactivity among fishes so that they have to avoid all species. Second, clinically relevant...... symptoms are linked to the presence of IgE-antibodies recognizing parvalbumin, the fish panallergen. This view was challenged by results from recent studies as follows. 1.

    The diagnostic workup of contact allergy to fragrances must not be limited to patch testing with the two well-established fragrance mixes. False-positive reactions to these mixes occur in up to 50 % of the patch tested patients. For the diagnostic work-up of positive reactions, and in cases of suspected fragrance allergy, patch testing with the single mix components and additional fragrances is mandatory. Frequently sensitizing fragrance materials are the 14 components of the two fragrance mixes and tree moss (Evernia furfuracea), ylang ylang oil (I + II; Cananga odorata), lemongrass oil (Cymbopogon schoenanthus), sandalwood oil (Santalum album), jasmine absolute (Jasminum spp.), and, less frequently, clove oil (Eugenia caryophyllus), cedarwood oil (Cedrus atlantica/deodara, Juniperus virginiana), Neroli oil (Citrus aurantium amara flower oil), salicylaldehyde, narcissus absolute (Narcissus spp.), and patchouli oil (Pogostemon cablin).

    Recent years have seen a marked increase in food allergy prevalence among children, particularly in Western countries, that cannot be explained by genetic factors alone. This has resulted in an increased effort to identify environmental risk factors underlying food allergies and to understand how these factors may be modified through interventions. Food allergy is an immune-mediated adverse reaction to food. Consequently, considerations of candidate risk factors have begun to focus on environ...

    Allergies are characterized by a hypersensitive immune reaction to originally harmless antigens. In recent decades, the incidence of allergic diseases has markedly increased, especially in developed countries. The increase in the frequency of allergic diseases is thought to be primarily due to environmental changes related to a westernized lifestyle, which affects the commensal microbes in the human body. The human gut is the largest organ colonized by bacteria and contains more than 1000 bacterial species, called the "gut microbiota." The recent development of sequencing technology has enabled researchers to genetically investigate and clarify the diversity of all species of commensal microbes. The collective genomes of commensal microbes are together called the "microbiome." Although the detailed mechanisms remain unclear, it has been proposed that the microbiota/microbiome, especially that in the gut, impacts the systemic immunity and metabolism, thus affecting the development of various immunological diseases, including allergies. In this review, we summarize the recent findings regarding the importance of the microbiome/microbiota in the development of allergic diseases and also the results of interventional studies using probiotics or prebiotics to prevent allergies.

    2016-10-01

    Food allergy has grown in rapidly in prevalence, currently affecting 5% of adults and 8% of children. Management strategy is currently limited to 1) food avoidance and 2) carrying and using rescue intramuscular epinephrine/adrenaline and oral antihistamines in the case of accidental ingestion; there is no FDA approved treatment. Recently, oral, sublingual and epicutaneous immunotherapy have been developed as active treatment of food allergy, though none have completed phase 3 study. Efficacy and safety studies of immunotherapy have been variable, though there is clearly signal that immunotherapy will be a viable option to desensitize patients. The use of bacterial adjuvants, anti-IgE monoclonal antibodies, and Chinese herbal formulations either alone or in addition to immunotherapy may hold promise as future options for active treatment. Active prevention of food allergy through early introduction of potentially offending foods in high-risk infants will be an important means to slow the rising incidence of sensitization.

    Full Text Available Summary Food allergy is a public health issue that has significantly increased worldwide in the past decade, affecting consumers’ quality of life and making increasing demands on health service resources. Despite recent advances in many areas of diagnosis and treatment, our general knowledge of the basic mechanisms of the disease remain limited i.e., not at pace with the exponential number of new cases and the explosion of new technologies. Many important key questions remain: What defines a major allergen? Why do some individuals develop food allergies and others do not? Which are the environmental factors? Could the environmental factors be monitored through epigenetics or modified by changes in the microbiome? Can tolerance to food be induced? Why are some foods more likely to trigger allergies than others? Does the route and timing of exposure have any role on sensitization? These and many other related questions remain unanswered. In this short review some of these topics are addressed in the light of recent advances in the area.

  7. Radioassay in allergy and immunology

    The discovering of IgE and the development of RIA to measure the amount of total IgE and assay IgE to specific allergens opened up a new dimension in the study of allergy. PRIST and RAST have been helpful in diagnosis as well as definition of new diseases and quality control of allergen extracts. A clinical diagnosis should not be based on an in vitro measurement alone, but must be combined with a clinical history, physical exam, and other diagnostic tests, such as skin tests. This combination of examinations is probably sufficient to make a diagnosis in the majority of cases, thus obviating the need for provocation testing, except where there are discrepancies in the data or no definitive results. Since provocation testing is time-consuming, uncomfortable, and potentially hazardous for the patient, any decrease in its frequency of use is significant. The standardization, purification, and separation of active fractions of allergens is essential to the further understanding and treatment of allergy and RAST is instrumental in this effort. It must always be kept in mind that the RAST is only as accurate and significant as the antigen that is linked to the disc. In cases where a purified, well-tested antigen is used, the results are excellent as with the codfish study. When the antigen is more variable and contains several proteins, results with RAST will be variable also. As more allergens are studied and purified, RAST will become a more important tool in allergy management

    Food allergy can result in considerable morbidity, impairment of quality of life, and healthcare expenditure. There is therefore interest in novel strategies for its treatment, particularly food allergen immunotherapy (FA-AIT) through the oral (OIT), sublingual (SLIT), or epicutaneous (EPIT) routes. This Guideline, prepared by the European Academy of Allergy and Clinical Immunology (EAACI) Task Force on Allergen Immunotherapy for IgE-mediated Food Allergy, aims to provide evidence-based recommendations for active treatment of IgE-mediated food allergy with FA-AIT. Immunotherapy relies on the delivery of gradually increasing doses of specific allergen to increase the threshold of reaction while on therapy (also known as desensitization) and ultimately to achieve post-discontinuation effectiveness (also known as tolerance or sustained unresponsiveness). Oral FA-AIT has most frequently been assessed: here, the allergen is either immediately swallowed (OIT) or held under the tongue for a period of time (SLIT). Overall, trials have found substantial benefit for patients undergoing either OIT or SLIT with respect to efficacy during treatment, particularly for cow's milk, hen's egg, and peanut allergies. A benefit post-discontinuation is also suggested, but not confirmed. Adverse events during FA-AIT have been frequently reported, but few subjects discontinue FA-AIT as a result of these. Taking into account the current evidence, FA-AIT should only be performed in research centers or in clinical centers with an extensive experience in FA-AIT. Patients and their families should be provided with information about the use of FA-AIT for IgE-mediated food allergy to allow them to make an informed decision about the therapy. © 2017 EAACI and John Wiley and Sons A/S.

Despite this, our diagnostic capabilities and techniques for managing patients with food allergies remain limited. We have conducted a systematic review of literature published within the last 5 years on the diagnosis and management of food allergies. While the gold standard for diagnosis remains the double-blind, placebo-controlled food challenge, this assessment is resource intensive and impractical in most clinical situations. In an effort to reduce the need for the double-blind, placebo-controlled food challenge, several risk-stratifying tests are employed, namely skin prick testing, measurement of serum-specific immunoglobulin E levels, component testing, and open food challenges. Management of food allergies typically involves allergen avoidance and carrying an epinephrine autoinjector. Clinical research trials of oral immunotherapy for some foods, including peanut, milk, egg, and peach, are under way. While oral immunotherapy is promising, its readiness for clinical application is controversial. In this review, we assess the latest studies published on the above diagnostic and management modalities, as well as novel strategies in the diagnosis and management of food allergy.

    The objective of this study was to compare the phospholipid content of conventional milk with that of organic milk and milk rich in conjugated linoleic acid (CLA). The membrane enclosing the fat globules of milk is composed, in part, of phospholipids, which have properties of interest for the development of so-called functional foods and technologically novel ingredients. They include phosphatidylethanolamine (PE), phosphatidylinositol (PI), phosphatidylcholine (PC), phosphatidylserine (PS), and the sphingophospholipid sphingomyelin (SM). Milk from organically managed cows contains higher levels of vitamins, antioxidants, and unsaturated fatty acids than conventionally produced milk, but we know of no study with analogous comparisons of major phospholipid contents. In addition, the use of polyunsaturated-lipid-rich feed supplement (extruded linseed) has been reported to increase the phospholipid content of milk. Because supplementation with linseed and increased unsaturated fatty acid content are the main dietary modifications used for production of CLA-rich milk, we investigated whether these modifications would lead to this milk having higher phospholipid content. We used HPLC with evaporative light scattering detection to determine PE, PI, PC, PS, and SM contents in 16 samples of organic milk and 8 samples of CLA-rich milk, in each case together with matching reference samples of conventionally produced milk taken on the same days and in the same geographical areas as the organic and CLA-rich samples. Compared with conventional milk and milk fat, organic milk and milk fat had significantly higher levels of all the phospholipids studied. This is attributable to the differences between the 2 systems of milk production, among which the most influential are probably differences in diet and physical exercise. The CLA-rich milk fat had significantly higher levels of PI, PS, and PC than conventional milk fat, which is also attributed to dietary differences: rations for

    Aeroallergens and food allergens are found to be relevant in atopic dermatitis. The atopy patch test (APT) can help to detect food allergies in children with atopic dermatitis. This study evaluates if the APT is a valuable tool in the diagnostic workup of children with food allergy-related atopic dermatitis. 42 children between 6 months and 12 years of age were selected at the Mofid Children Hospital. Atopic dermatitis was diagnosed, and the severity of the disease was determined. At the test visit, the patients underwent a skin prick test (SPT), APT, and serum IgE level measurement for cow's milk, egg yolk, egg white, wheat, and soy. We found a sensitivity of 91.7%, a specificity of 72.7%, a positive predictive value (PPV) of 88%, a negative predictive value (NPV) of 80%, and an accuracy of 85.7% for APT performed for cow's milk. APT performed for egg yolk had a sensitivity and a NPV of 100%, while the same parameters obtained with egg white were 84.2 and 75%, respectively. The sensitivity, specificity, and NPV of the APT for wheat were 100, 75, and 100%, respectively. The sensitivity, PPV, and NPV of the APT for soy were 87.5, 70, and 87.5%, respectively. Our data demonstrate that the APT is a reliable diagnostic tool to evaluate suspected food allergy-related skin symptoms in childhood and infancy. © 2018 S. Karger AG, Basel.

    A food allergy is defined as "a phenomenon in which adverse reactions are caused through antigen-specific immunological mechanisms after exposure to given food." Various symptoms of food allergy occur in many organs. Food allergies are classified roughly into 4 clinical types: (1) neonatal and infantile gastrointestinal allergy, (2) infantile atopic dermatitis associated with food allergy, (3) immediate-type food allergy (urticaria, anaphylaxis, etc.), and (4) food dependent exercise-induced anaphylaxis and oral allergy syndrome (i.e., specific forms of immediate food allergy). The therapy for food allergies includes treatment of and prophylactic measures against hypersensitivity such as anaphylaxis. A fundamental prophylactic measure is the elimination diet. However, elimination diets should be used only if necessary because of the patient-related burden. For this purpose, it is very important that causative foods be accurately identified. There are a number of means available to identify causative foods, including the history taking, a skin prick test, detection of antigen-specific IgE antibodies in the blood, the basophil histamine release test, the elimination diet test, and the oral challenge test, etc. Of these, the oral challenge test is the most reliable. However, it should be conducted under the supervision of experienced physicians because it may cause adverse reactions, such as anaphylaxis.

    The purpose of this review is to improve otolaryngologists' antibiotic stewardship by detailing current approaches to penicillin allergy. Although up to 15% of hospitalized patients in the United States have a penicillin allergy recorded on their charts, fewer than 10% of these have a true penicillin allergy. Using a combination of a detailed allergy history, skin testing and graded-dose administration, many patients whose charts say 'penicillin-allergic' can safely be treated with penicillin and cross-reacting antibiotics. This permits use of narrower-spectrum antibiotics and saves money.

    Recent studies on cashew nut allergy suggest that the prevalence of cashew nut allergy is increasing. Cashew nut consumption by allergic patients can cause severe reactions, including anaphylaxis. This review summarizes current knowledge on cashew nut allergy to facilitate timely clinical recognition and to promote awareness of this emerging food allergy amongst clinicians. The goal of this study is to present a systematic review focused on the clinical aspects of allergy to cashew nut including the characteristics of cashew nut, the prevalence, allergenic components, cross-reactivity, diagnosis and management of cashew nut allergy. The literature search yielded 255 articles of which 40 met our selection criteria and were considered to be relevant for this review. The 40 articles included one prospective study, six retrospective studies and seven case reports. The remaining 26 papers were not directly related to cashew nut allergy. The literature suggests that the prevalence of cashew nut allergy is increasing, although the level of evidence for this is low. A minimal amount of cashew nut allergen may cause a severe allergic reaction, suggesting high potency comparable with other tree nuts and peanuts. Cashew allergy is clearly an underestimated important healthcare problem, especially in children. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Penicillin allergy is commonly reported in the pediatric emergency department (ED). True penicillin allergy is rare, yet the diagnosis results from the denial of first-line antibiotics. We hypothesize that all children presenting to the pediatric ED with symptoms deemed to be low-risk for immunoglobulin E-mediated hypersensitivity will return negative results for true penicillin allergy. Parents of children aged 4 to 18 years old presenting to the pediatric ED with a history of parent-reported penicillin allergy completed an allergy questionnaire. A prespecified 100 children categorized as low-risk on the basis of reported symptoms completed penicillin allergy testing by using a standard 3-tier testing process. The percent of children with negative allergy testing results was calculated with a 95% confidence interval. Five hundred ninety-seven parents completed the questionnaire describing their child's reported allergy symptoms. Three hundred two (51%) children had low-risk symptoms and were eligible for testing. Of those, 100 children were tested for penicillin allergy. The median (interquartile range) age at testing was 9 years (5-12). The median (interquartile range) age at allergy diagnosis was 1 year (9 months-3 years). Rash (97 [97%]) and itching (63 [63%]) were the most commonly reported allergy symptoms. Overall, 100 children (100%; 95% confidence interval 96.4%-100%) were found to have negative results for penicillin allergy and had their labeled penicillin allergy removed from their medical record. All children categorized as low-risk by our penicillin allergy questionnaire were found to have negative results for true penicillin allergy. The utilization of this questionnaire in the pediatric ED may facilitate increased use of first-line penicillin antibiotics. Copyright © 2017 by the American Academy of Pediatrics.

For every allergen assessed, parents reported more food reactions than positive skin prick test results. Allergy incidence were caused, in order, by cow’s milk and chicken (25.3%, eggs (22.1%, chocolate (20.1%, fruits (14.3%, seafood (13%, and saltwater fish (1.9%. Kappa coefficient are all poor (0.05 except for chicken (P=0.02. Conclusion Most parents tend to overestimate which food cause reactions in their children, as reactions reported were not necessarily allergenic. Therefore, every patient experiencing allergy reactions should undergo skin prick testing to confirm the possibility of allergy.

    Food allergy is an adverse immune response to dietary proteins. Hydrolysates are frequently used for children with milk allergy. However, hydrolysates effects afterwards are poorly studied. The aim of this study was to investigate the immunological consequences of hydrolyzed whey protein in allergic mice. For that, we developed a novel model of food allergy in BALB/c mice sensitized with alum-adsorbed β-lactoglobulin. These mice were orally challenged with either whey protein or whey hydrolysate. Whey-challenged mice had elevated levels of specific IgE and lost weight. They also presented gut inflammation, enhanced levels of SIgA and IL-5 as well as decreased production of IL-4 and IL-10 in the intestinal mucosa. Conversely, mice challenged with hydrolyzate maintained normal levels of IgE, IL-4 and IL-5 and showed no sign of gut inflammation probably due to increased IL-12 production in the gut. Thus, consumption of hydrolysate prevented the development of clinical signs of food allergy in mice. Copyright © 2015 Elsevier Inc. All rights reserved.

    Atopic dermatitis (AD) is an inflammatory disease of the skin, which is characterised by a chronic relapsing course. The aim of the study was to assign the prevalence of clinically active food allergies among a group of children between 3 months and 7 years of age, with AD. Eighty-eight children with AD were screened for specific IgE antibodies to food proteins. All patients with AD and specific IgE antibodies to food proteins were subjected to Oral Food Challenges (OFCs) with the relevant foods. Food-sensitised patients with moderate levels of sIgE had clinically active food allergy to milk (39.28%) and egg (42.34%) on the basis of positive OFCs. High IgE and eosinophilia had a prevalence of almost 80% and 25%, regardless of concomitant food sensitisation and disease severity. In this study, clinically active food allergies were recognised in 26.13% of children with AD. Nevertheless, no association was confirmed between food sensitisation and AD severity. High IgE and peripheral eosinophilia have not been found more prevalent among children with severe AD nor among children with food sensitisation. Infants and younger children with AD should be screened for an underlying food allergy, regardless of disease severity. Copyright © 2016 SEICAP. Published by Elsevier España, S.L.U.

    Probiotics are used in the treatment of allergic diseases. We investigated the safety of probiotics for subjects with food allergy. Labels of probiotics commercially available in Spain were examined to assess their content of cow's milk or hen's egg. Skin prick tests with these compounds (20 mg/ml) were performed in five children allergic to cow's milk, five children allergic to hen's white egg, and five control subjects non-allergic to food. Three serum pools: I (positive-specific IgE to cow's milk and hen's egg white proteins), II (positive-specific IgE to cow's milk and negative to hen's egg white proteins), and III (negative-specific IgE to cow's milk and positive to hen's egg white proteins) were used to detect cow's milk and hen's egg white allergens in probiotics. ImmunoCAP(®) (Phadia), in-house ELISA, SDS-PAGE immunoblotting, and inhibition studies of these assays were performed. Proteins were quantified by enzyme-immunoassay. Eleven probiotics were studied. No label advertised about egg content, eight labels warned about lactose, lactic acid or cow's milk, one label claimed to be milk-free, and two gave no information. Cow's milk proteins were detected, by at least one lab technique, in 10/11 probiotics, three over 2.5 mg/kg (21, 52, 112 mg/kg). Hen's egg white proteins were detected in 3/11 probiotics, only one had more than 2.5 mg/kg (47 mg/kg). Probiotic compounds may contain hidden allergens of food and may not be safe for subjects with allergy to cow's milk or hen's egg. © 2012 John Wiley & Sons A/S.

    Gastroenterology nurses and associates will find it helpful to be informed about milk thistle (silybum marianum), a popular, safe and promising herb used by patients with liver disease. Silymarin is a derivative from the milk thistle plant with few side effects that has been safely used for centuries to treat liver ailments. Since the 1970s, there has been a reemergence of the marketing and use of silymarin. Research results of some small studies suggest silymarin has hepatoprotective, antiinflammatory, and regenerative properties producing a beneficial effect for some types of hepatitis. It is unclear, however, whether silymarin might interfere with the effect of interferon or ribavirin. A well-designed, placebo-controlled study of a larger population is needed. It is certainly encouraging that a large collaborative study is currently underway for milk thistle therapy in hepatitis C. This study is funded by NCCAM, the National Institute of Allergy and Infectious Diseases (NIAID), and the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).

    According to Hansen's contact rule, the digestive system should be considered as the main shock organ, yet in food allergy, this is not the case. Very often specific food triggers clinical manifestations not involving the digestive system; that is, reactions are manifested either in the respiratory system, as asthma or rhinitis, or in the skin. In these cases the BALT (broncho-alveolar lymphoid tissue) and GALT (gastrointestinal lymphoid tissue) units play a basic role in the sensitizations. The purpose of this study was to determine the most frequent skin manifestations of food allergy among children, and the most frequently involved foods. We also thought it interesting to evaluate the diagnostic reliability of the different standard immunological parameters utilized by the study team in food allergy. All patients underwent intracutaneous tests with 12 groups of the most frequent food allergens, as well as serum IgE, antigen-specific IgE against foods, and antigen-specific histamine release tests. Antigen-specific IgG4 determination was performed in some cases. The results obtained confirmed previous studies, the most common manifestations being: angioedema (48%), followed by urticaria (31%) and atopic dermatitis (21%). Regarding the frequency of sensitization to different food allergens, in mono- or polisensitization, fish and egg stand out in our environment. Certain food allergens are more frequently responsible for specific skin manifestations. Thus, for fish sensitization, the most frequent skin manifestation is atopic dermatitis (50%); for egg sensitization, angioedema is the most frequent skin manifestation (50%); and for milk, urticaria (50%). Finally, and in agreement with previous works regarding the diagnostic reliability of in vitro techniques, we found that the histamine release test offered the highest percentage of diagnostic reliability. Only for sensitization to milk proteins did antigen-specific IgE demonstrate higher reliability. Once again, we

    Food allergy affects a large part of the population and their numbers are increasing. Although the knowing of this pathology is growing, allergic patients have really difficulties to lead a normal life, especially with food. Until now,this group hadn t practical tools that would help them in the development of a balanced daily diet, as there are for the general population in the form of pyramids and dietary guidelines . This work has covered this need for two of the most prevalent allergies in early life. gather information on the allergy of cow's milk protein and egg, to design a food pyramid for these patients, based on the consensus, recommendations and scientific guidance. After confirming the absence of a similar work, food pyramids allergy to egg and cow's milk protein, adapted to each, and a joint pyramid is designed to both allergies. Besides basic recommendations for healthy eating were included in general and in particular individuals, with special interest for the collective (food hygiene, food additives, cosmetics, medicines, etc). Due to the importance of nutrition in childhood and acquires the underlying difficulties this group, to properly plan the diet is very important as it can prevent accidents and long-term nutritional deficiencies. Therefore provide graphical tools and practices to this goal, is importance for population and medical and scientific community, and is the result of this work. Copyright AULA MEDICA EDICIONES 2014.

    Studies suggest an increase in food allergy prevalence over the last decade, but the contributing factors remain unknown. The aim of this study was to evaluate the association between the most common food allergies and atopic history, sociodemographic characteristics and lifestyle habits. We conducted a case-control study nested within the SPAACE study (Surveying Prevalence of Food Allergy in All Canadian Environments) – a cross-Canada, random telephone survey. Cases consisted of individuals with probable food allergy (self-report of convincing symptoms and/or physician diagnosis) to milk, egg, peanut, tree nut, shellfish, fish, wheat, soy, or sesame. Controls consisted of nonallergic individuals, matched for age. Cases and controls were queried on personal and family history of atopy, sociodemographic characteristics and lifestyle habits. Multivariate logistic regression was used to evaluate the association between atopy, sociodemographic characteristics and lifestyle habits with probable food allergy. Between September 2010 and September 2011, 480 cases and 4,950 controls completed the questionnaire. For all 9 allergens, factors associated with a higher risk of probable allergy were as follows: (1) personal history of eczema (in the first 2 years of life), asthma or hay fever (odds ratio, OR 2.3, 95% CI 1.6-3.5; OR 2.8, 95% CI 2.2-3.6, and OR 2.3, 95% CI 1.8-3.0, respectively), (2) maternal, paternal or sibling's food allergy (OR 3.7, 95% CI 2.5-5.6; OR 3.0, 95% CI 1.8-5.1, and OR 3.1, 95% CI 2.2-4.2), (3) high household income (top 20%; OR 1.5, 95% CI 1.2-2.0). Males and older individuals were less likely to have food allergy (OR 0.7, 95% CI 0.6-0.9, and OR 0.99, 95% CI 0.99-1.00). Eczema in the first 2 years of life was the strongest risk factor for egg, peanut, tree nut and fish allergy. This is the largest population-based nested case-control study exploring factors associated with food allergies. Our results reveal that, in addition to previously reported
