    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.

    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.

    Food allergy must have an immunological background. Till recently it was restricted only to the IgE mechanism, today we include also non-atopical reactions (in particular type III and IV according to Coombs and Gell). We speak of probable and possible food allergies. By differential diagnosis we must differentiate food allergies from food intolerance (e.g. enzyme deficiencies), food aversions (psychic factor) as well as toxic and pharmacological effects. There are more than 10% undesirable reactions in humans after ingestion of food but only every fifth (some 2% of the population have food allergies. The diagnosis is based above all on the case-history, subsequent elimination and exposure tests and examination by allergological tests, or examination of specific immunoglobulins E (IgE). The diagnosis is not always unequivocal--it is influenced among others by a different specificity and sensitivity of food antigens (allergens). The manifestations of food allergy are found at the site of action (mouth, GIT) or are systemic (respiration, cardiovascular system, skin etc.). A special type of food allergy is the oral alimentary syndrome, i.e. food allergy crossed with pollen hypersensitivity, described in the great majority of subjects sensitive to pollen. Food allergy has its specific age-conditioned and geographical features. In childhood sensitivity to the protein of cows milk, egg white but also soya or flour predominates, with advancing age allergies to nuts, fruit, vegetables, spices, cheese, sea foods increase. Food allergy can be a very early allergy (manifested already in infant age) but it is one of the few allergies which can also recede (incl. laboratory tests). Treatment is dietetic, the period of dietetic treatment depends on the type of food and the patient's age, not infrequently it must be lifelong. If diet does not suffice, preventive medication is used (sodium cromoglycate) or symptomatic (antihistamine preparations, corticosteroids, external agents

    An adverse drug reaction relates to an undesired response to administration of a drug. Type A reactions are common and are predictable to administration, dose response, or interaction with other medications. Type B reactions are uncommon with occurrences that are not predictable. Appropriate diagnosis, classification, and entry into the chart are important to avoid future problems. The diagnosis is made with careful history, physical examination, and possibly allergy testing. It is recommended that help from allergy immunology specialists should be sought where necessary and that routine prescription of Epi pen should be given to patients with multiple allergy syndromes.

    Full Text Available Abstract Drug allergy encompasses a spectrum of immunologically-mediated hypersensitivity reactions with varying mechanisms and clinical presentations. This type of adverse drug reaction (ADR not only affects patient quality of life, but may also lead to delayed treatment, unnecessary investigations, and even mortality. Given the myriad of symptoms associated with the condition, diagnosis is often challenging. Therefore, referral to an allergist experienced in the identification, diagnosis and management of drug allergy is recommended if a drug-induced allergic reaction is suspected. Diagnosis relies on a careful history and physical examination. In some instances, skin testing, graded challenges and induction of drug tolerance procedures may be required. The most effective strategy for the management of drug allergy is avoidance or discontinuation of the offending drug. When available, alternative medications with unrelated chemical structures should be substituted. Cross-reactivity among drugs should be taken into consideration when choosing alternative agents. Additional therapy for drug hypersensitivity reactions is largely supportive and may include topical corticosteroids, oral antihistamines and, in severe cases, systemic corticosteroids. In the event of anaphylaxis, the treatment of choice is injectable epinephrine. If a particular drug to which the patient is allergic is indicated and there is no suitable alternative, induction of drug tolerance procedures may be considered to induce temporary tolerance to the drug. This article provides a backgrounder on drug allergy and strategies for the diagnosis and management of some of the most common drug-induced allergic reactions, such allergies to penicillin, sulfonamides, cephalosporins, radiocontrast media, local anesthetics, general anesthetics, acetylsalicylic acid (ASA and non-steroidal anti-inflammatory drugs.

    2007-12-01

    Egg allergy is one of the most common food allergies in infants and young children. The great majority is not life-threatening and management involves exclusion of egg from the diet and regular review with the expectation that the majority of children will outgrow the allergy by school age. Judgment is required as to when the dietary elimination of egg is no longer required. This decision may be helped by demonstrating loss of sensitivity by skin prick or specific IgE testing and in some cases a supervised food challenge. Particular issues in management arise with more severe, potentially life-threatening reactions, with immunization with vaccines prepared in eggs, with the diagnosis of egg hypersensitivity as a cause of delayed exacerbations of eczema which can be non-IgE mediated, and in deciding whether a child can be allowed to ingest small amounts of cooked egg through egg-containing foods while continuing to avoid raw egg or larger amounts of whole egg. Cases which illustrate these issues are presented. PMID:18078424

    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.

The latter is surprising because allergy represents a hyper-immune response based on immunoglobulin E production against harmless environmental antigens, i.e., allergens. Nevertheless, vaccination with allergens, termed allergen-specific immunotherapy is the only disease-modifying therapy of allergy with long-lasting effects. New forms of allergy diagnosis and allergy vaccines based on recombinant allergen-derivatives, peptides and allergen genes have emerged through molecular allergen characterization. The molecular allergy vaccines allow sophisticated targeting of the immune system and may eliminate side effects which so far have limited the use of traditional allergen extract-based vaccines. Successful clinical trials performed with the new vaccines indicate that broad allergy vaccination is on the horizon and may help to control the allergy pandemic. PMID:22521141

    2015-01-01

    Food allergy is defined as an immune system-mediated adverse reaction to food components. Food allergic reactions are mostly IgE mediated and also known as immediate type hypersensitivity (type I reaction). There are several characteristic clinical types of food allergy, such as Anaphylaxis, Food-dependent exercise-induced anaphylaxis (FDEIA), and Oral allergy syndrome (OAS). In addition, food allergy is also classified into two types (class 1 and class 2) based on the pathophysiological mechanism. In the class 2 food allergy, pollen allergy causes plant food allergy; therefore this type of allergy is sometimes called Pollen-food allergy syndrome (PFAS). The risk of food allergy (allergenicity) may vary with the treatment of the food allergens. The formation or status of the causative food affects its allergenicity. Class 1 food allergens are generally heat-, enzyme-, and low pH-resistant glycoproteins ranging in size from 10 to 70 kD. Class 1 food allergens induce allergic sensitization via the gastrointestinal tract and are responsible for systemic reactions. Class 2 food allergens are generally heat-labile, susceptible to digestion, and highly homologous with pollen allergens. Taken together, it may be important to consider the diversity of food allergy in order to fight against food allergy. PMID:26598816

    Food allergies can result in life-threatening reactions and diminish quality of life. In the last several decades, the prevalence of food allergies has increased in several regions throughout the world. Although more than 170 foods have been identified as being potentially allergenic, a minority of these foods cause the majority of reactions, and common food allergens vary between geographic regions. Treatment of food allergy involves strict avoidance of the trigger food. Medications manage symptoms of disease, but currently, there is no cure for food allergy. In light of the increasing burden of allergic diseases, the American Academy of Allergy, Asthma & Immunology; European Academy of Allergy and Clinical Immunology; World Allergy Organization; and American College of Allergy, Asthma & Immunology have come together to increase the communication of information about allergies and asthma at a global level. Within the framework of this collaboration, termed the International Collaboration in Asthma, Allergy and Immunology, a series of consensus documents called International Consensus ON (ICON) are being developed to serve as an important resource and support physicians in managing different allergic diseases. An author group was formed to describe the natural history, prevalence, diagnosis, and treatment of food allergies in the context of the global community. PMID:22365653

    Food allergies can result in life-threatening reactions and diminish quality of life. The prevalence of food allergies has increased in several regions throughout the world. A few food allergens cover the majority of food-related reactions (milk, egg, wheat, soy, fish, crustacean, nuts and peanut). Immunological mechanisms range between IgE-mediated (most common) and non-IgE-mediated, the latter of which remaining often a clue in the diagnosis. Treatment of food allergy involves strict avoidance of the trigger food. Medications help to manage symptoms of disease, but currently, there is no cure for food allergy. PMID:23179672

    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.

    IgE-mediated immediate type reactions are the most common form of food allergy in childhood. Primary (often in early childhood) and secondary (often pollen-associated) allergies can be distinguished by their level of severity. Hen's egg, cow's milk and peanut are the most common elicitors of primary food allergy. Tolerance development in hen's egg and cow's milk allergy happens frequently whereas peanut allergy tends toward a lifelong disease. For the diagnostic patient history, detection of sensitization and (in many cases) oral food challenges are necessary. Especially in peanut and hazelnut allergy component-resolves diagnostic (measurement of specific IgE to individual allergens, e. g. Ara h 2) seem to be helpful. In regard to therapy elimination diet is still the only approved approach. Patient education through dieticians is extremely helpful in this regard. Patients at risk for anaphylactic reactions need to carry emergency medications including an adrenaline auto-injector. Instruction on the usage of the adrenaline auto-injector should take place and a written management plan handed to the patient. Moreover, patients or caregivers should be encouraged to attending a structured educational intervention on knowledge and emergency management. In parallel, causal therapeutic options such as oral, sublingual or epicutaneous immunotherapies are currently under development. In regard to prevention of food allergy current guidelines no longer advise to avoid highly allergenic foods. Current intervention studies are investigating wether early introduction of highly allergic foods is effective and safe to prevent food allergy. It was recently shown that peanut introduction between 4 and 11  months of age in infants with severe atopic dermatitis and/or hen's egg allergy (if they are not already peanut allergic) prevents peanut allergy in a country with high prevalence.

    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.

    Food allergies are a global health issue with increasing prevalence. Allergic reactions can range from mild local symptoms to severe anaphylactic reactions. Significant progress has been made in diagnostic tools such as component-resolved diagnostics and its impact on risk stratification as well as in therapeutic approaches including biologicals. However, a cure for food allergy has not yet been achieved and patients and their families are forced to alter eating habits and social engagements, impacting their quality of life. New technologies and improved in vitro and in vivo models will advance our knowledge of the pathogenesis of food allergies and multicenter-multinational cohort studies will elucidate interactions between genetic background, lifestyle, and environmental factors. This review focuses on new insights and developments in the field of food allergy and summarizes recently published articles. PMID:26443043

    Fruit and vegetable allergies are the most prevalent food allergies in adolescents and adults. The identification of the allergens involved and the elucidation of their intrinsic properties and cross-reactivity patterns has helped in the understanding of the mechanisms of sensitisation and how the allergen profiles determine the different phenotypes. The most frequent yet contrasting fruit and vegetable allergies are pollen-food syndrome (PFS) and lipid transfer protein (LTP) syndrome. In PFS, fruit and vegetable allergies result from a primary sensitisation to labile pollen allergens, such as Bet v 1 or profilin, and the resulting phenotype is mainly mild, consisting of local oropharyngeal reactions. In contrast, LTP syndrome results from a primary sensitisation to LTPs, which are stable plant food allergens, inducing frequent systemic reactions and even anaphylaxis. Although much less prevalent, severe fruit allergies may be associated with latex (latex-fruit syndrome). Molecular diagnosis is essential in guiding the management and risk assessment of these patients. Current management strategies comprise avoidance and rescue medication, including adrenaline, for severe LTP allergies. Specific immunotherapy with pollen is not indicated to treat pollen-food syndrome, but sublingual immunotherapy with LTPs seems to be a promising therapy for LTP syndrome. PMID:26022876

    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.

    Food allergy, defined as an adverse immune response to food proteins, affects as many as 6% of young children and 3% to 4% of adults. Food-induced allergic reactions are responsible for a variety of symptoms involving the skin, gastrointestinal tract, and respiratory tract and might be caused by IgE-mediated and non-IgE-mediated (cellular) mechanisms. Our understanding of how food allergy represents an abrogation of normal oral tolerance is evolving. Although any food can provoke a reaction, relatively few foods are responsible for the vast majority of significant food-induced allergic reactions: milk, egg, peanuts, tree nuts, fish, and shellfish. A systematic approach to diagnosis includes a careful history, followed by laboratory studies, elimination diets, and often food challenges to confirm a diagnosis. Many food allergens have been characterized at a molecular level, which has increased our understanding of the immunopathogenesis of food allergy and might soon lead to novel diagnostic and therapeutic approaches. Currently, management of food allergies consists of educating the patient to avoid ingesting the responsible allergen and to initiate therapy in case of an unintended ingestion. PMID:16455349

  6. 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.

    Chang, Christopher; Mahmood, Mubashar M; Teuber, Suzanne S; Gershwin, M Eric

    2012-08-01

    Allergy to penicillin is the most commonly reported antibiotic allergy. However, most patients who report a positive history of a prior reaction to penicillin are not found to be allergic to penicillin upon skin testing. Often, this history is vague or based on a parent's recollection of an event that occurred in the distant past. Avoidance of penicillin based on self-reported allergic history alone often leads to the use of an alternate antibiotic with greater cost or side effect profile. Patients with a negative skin test to both major and minor determinants may generally be given penicillin, with a statistical risk of developing an allergic reaction similar to that observed in the general population. A more cautious approach in these cases where the degree of suspicion is low, an allergic etiology is unproven, or there is a negative skin test, is to do a graded challenge. If the skin test is positive, an alternate antibiotic should be used. If, however, an alternate antibiotic is not available, then desensitization may be performed, but there are limitations to desensitization as well, and tolerance is not permanent. Avoidance of cephalosporins may be recommended in cases of penicillin allergy, but newer generation cephalosporins have demonstrate less cross-reactivity to penicillin than earlier generation ones. Desensitization protocols for cephalosporins are available but not standardized. The mechanisms of antibiotic sensitization are not clearly understood. PMID:21789743

  8. Symptoms of food allergy.

    Science.gov (United States)

    Fotherby, K J; Hunter, J O

    1985-07-01

    Adverse reactions to foods can be due to many causes, but only those involving an immunological mechanism can be defined as food allergic disease. An increasing number of gastrointestinal and other diseases are being shown to involve food intolerances. Immediate reactions with symptoms within hours of eating a particular food are most readily shown to be due to food allergy and are often associated with the presence of food-specific IgE as shown by skin prick tests and RASTs. When reactions are delayed for 24 to 48 hours or more, underlying food intolerance is harder to recognize and much less often shown to be due to allergy. At present, diagnosis and management depends on dietary manipulation, showing that symptoms improve on food avoidance and are reproduced by food challenge (preferably double-blind). Further understanding of the mechanisms involved in food allergy, in Crohn's disease and irritable bowel syndrome may allow the development of simple tests to identify the foods concerned and perhaps, in the case of allergic disease, cure by the induction of tolerance.

In genetically predisposed individuals, wheat can cause specific immune responses. A food allergy to wheat is characterized by T helper type 2 activation which can result in immunoglobulin E (IgE and non-IgE mediated reactions. IgE mediated reactions are immediate, are characterized by the presence of wheat-specific IgE antibodies, and can be life-threatening. Non-IgE mediated reactions are characterized by chronic eosinophilic and lymphocytic infiltration of the gastrointestinal tract. IgE mediated responses to wheat can be related to wheat ingestion (food allergy or wheat inhalation (respiratory allergy. A food allergy to wheat is more common in children and can be associated with a severe reaction such as anaphylaxis and wheat-dependent, exercise-induced anaphylaxis. An inhalation induced IgE mediated wheat allergy can cause baker’s asthma or rhinitis, which are common occupational diseases in workers who have significant repetitive exposure to wheat flour, such as bakers. Non-IgE mediated food allergy reactions to wheat are mainly eosinophilic esophagitis (EoE or eosinophilic gastritis (EG, which are both characterized by chronic eosinophilic inflammation. EG is a systemic disease, and is associated with severe inflammation that requires oral steroids to resolve. EoE is a less severe disease, which can lead to complications in feeding intolerance and fibrosis. In both EoE and EG, wheat allergy diagnosis is based on both an elimination diet preceded by a tissue biopsy obtained by esophagogastroduodenoscopy in order to show the effectiveness of the diet. Diagnosis of IgE mediated wheat allergy is based on the medical history, the detection of specific IgE to wheat, and oral food challenges. Currently, the main treatment of a

    Anesthesia may often be considered as a high-risk procedure and anaphylaxis remains a major cause of concern for anesthetists who routinely administer many potentially allergenic agents. Neuromuscular blocking agents, latex and antibiotics are the substances involved in most of the reported reactions. Besides these three agents, a wide variety of substances may cause an anaphylactic reaction during anesthesia. Basically all the administered drugs or substances may be potential causes of anaphylaxis. Among them, those reported the most in literature include hypnotics, opioids, local anesthetics, colloids, dye, Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), Iodinated Contrast Media (ICM), antiseptics, aprotinin, ethylene oxyde and formaldehyde, and protamine and heparins. No premedication can effectively prevent an allergic reaction and a systematic preoperative screening is not justified for all patients; nevertheless, an allergy specialist should evaluate those patients with a history of anesthesia-related allergy. Patients must be fully informed of investigation results, and advised to provide a detailed report prior to future anesthesia. PMID:22014927

    Food allergies have increased in recent decades. However, they cannot be effectively treated by the current management, which is limited to the identification and avoidance of foods that induce allergies and to the use of medicines for symptoms relief. To meet the medical need of prevention and cure of food allergies, several therapeutic strategies are under investigation. Some newly developed biologics such as anti-IgE antibody and anti-interleukin (IL)-5 antibody directed against significant molecules in the allergic process have shown their potential for the treatment of food allergies. Allergen-specific immunotherapy is the therapy that induces immune tolerance and may reduce the need for conventional medication, severity of allergic symptoms and eliminate hypersensitivity. In this article, clinical studies of immunotherapy via subcutaneous, oral, sublingual, and epicutaneous routes are extensively reviewed for their safety and effectiveness on various food allergies. In addition, to reduce the risk of anaphylaxis and increase toleragenic immunity, many studies are focusing on the modification of traditional allergens used for immunotherapy. Moreover, a Chinese herbal formulation with potential anti-allergic effects is being evaluated for its efficacy in patients with peanut allergy. Although more studies are needed, accumulated data of current studies represent compelling evidence of curative effects of some strategies and give a hope that food allergies are likely to be successfully treated in the future.

    Full Text Available Food allergy and intolerance are wide spread nowadays. However, the problem existed and was registered and described still by the ancients. It was fully understood and scientifically depicted in the 20th century after IgE and anaphylaxis were discovered, new diagnostic tests were initiated and the term “allergy” was introduced. There are some interesting aspects of the problem. Epidemiology is the first one – in the last two decades the number of people suffering from food allergy increased significantly and reached 4% of the population. Food allergy covers all ages, both sexes; atopic people and these with other allergic or digestive diseases are in the risk group also. There is certain influence of the eating habits as well. Etiology is rich and varied. It includes all foodstuffs of plant and animal origin, spices, honey, medicinal products - milk, eggs, meat, fish, nuts, fruits and vegetables, etc. Pathogenesis is complex.

    The progressive understanding of the nature and mechanisms of T regulatory (Treg) cells in the last decade has changed the concept of immune tolerance, that is no longer considered as a mere lack of immune reactivity but as a finely regulated process that requires specific activity of cells, adhesion and secreted molecules. Tregs play a key role in maintenance of self-tolerance and induction of tolerance against ubiquitous innocuous non-self antigens, so preventing the onset of autoimmune diseases and allergies. This review will focus on the Treg response in allergy that is characterized by a down-regulation of allergen specific T cell proliferation and inhibition of both Th1 and Th2 cytokines production. Hence, Treg cells suppress allergen-specific Th1 and Th2 cell responses playing an important role in the physiological immune response to allergens. Further, Treg cells are able to suppress IgE production by B lymphocytes and directly or indirectly inhibit the activity of allergic inflammation effector cells, namely eosinophils, basophils and mastcells. Finally, increasing evidence suggests that Treg cells are also implicated in chronicity development of inflammatory diseases. This appears to happen through a fine interaction they entertain with resident tissue cells and has been particularly highlighted in the study of airways remodeling in asthma. The understanding of the mechanisms underlying allergen tolerance has brought new interest in the development of new allergy treatment, able to target Treg cells, both in allergy prevention and in the therapy of established allergy.

    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.

    Food allergy is a common disease that is rapidly increasing in prevalence for reasons that remain unknown. Current research efforts are focused on understanding the immune basis of food allergy, identifying environmental factors that may contribute to its rising prevalence, and developing immunotherapeutic approaches to establish immune tolerance to foods. Technological advances such as peptide microarray and MHC class II tetramers have begun to provide a comprehensive profile of the immune response to foods. The burgeoning field of mucosal immunology has provided intriguing clues to the role of the diet and the microbiota as risk factors in the development of food allergy. The purpose of this review is to highlight significant gaps in our knowledge that need answers to stem the progression of this disorder that is reaching epidemic proportions. PMID:23648309

    IgE-mediated hypersensitivity reactions account for the majority of well-documented food allergy reactions, but non-IgE-mediated immune mechanisms do cause some hypersensitivity disorders. A variety of gastrointestinal, cutaneous, respiratory, and generalized symptoms and syndromes have been associated with IgE-mediated food allergy. The diagnostic approach to adverse food reactions begins with a careful medical history and physical examination. Laboratory studies may then be used appropriately in the evaluation. Once the diagnosis of food allergy is established, the only proven therapy is the strict elimination of the food from the patient's diet. Studies in both children and adults indicate that symptomatic reactivity to food allergens is often lost over time, except possibly reactions to peanuts, tree nuts, and seafood. PMID:12023192

    1998-05-05

    This paper describes the mechanism of allergy. Allergy is defined as the immune reaction which causes tissue damage instead of its original role for body defense. Usually, antibodies of IgE (immunoglobulin E) class are formed against some substances, to remove antigens through one-to-one reaction (specific reaction) with antigens. However, it is improper for bodies hurriedly to exhaust harmless substances such as pollens by a large amount of snivel and sneezes, which is called allergy. Genetic and environmental factors relate to allergy. In addition, the response of nerve and the sensitivity of tissue are related to the development of symptoms, which makes things complicated. There are allergic reactions caused by the immune complex formed by antigens and antibodies of IgE class or by the cytokine production from T lymphocytes responding to the antigen. In the living environment, allergic reactions are caused by allergens which are antigens causing allergy, such as ticks and mold particles in houses, stimulating and sensitive substances for bronchus, such as formalin from building materials, and antibody production inducing substances. 7 figs.

    Food allergy is a potentially life-threatening condition with no approved therapies, apart from avoidance and injectable epinephrine for acute allergic reactions. Oral immunotherapy (OIT) is an experimental treatment in which food-allergic patients consume gradually increasing quantities of the food to increase their threshold for allergic reaction. This therapy carries significant risk of allergic reactions. The ability of OIT to desensitize patients to particular foods is well-documented, although the ability to induce tolerance has not been established. This review focuses on recent studies for the treatment of food allergies such as cow's milk, hen's egg, and peanut. PMID:26617227

  15. [Current features of food allergies: the need of allergy surveillance].

    2001-01-01

    The prevalence of food allergy in European populations has been evaluated at between 1.8 and 4.4%. In the French population it is 3.24%. This frequency, as well as the gravity of some manifestations, has already led to preventive and curative measures being taken in school settings. This increase is related to multiple environmental factors: changes in intestinal microflora, early diversification of foods in children, interference of drugs favoring clinical severity in adults. Allergenicity can be modified by food industry techniques. The appearance of novel foods (exotic proteins or those derived from animal feed, and soon GMOs), the growing use of food proteins as ingredients, constitute new risks. The absence of validated experimental methods for evaluating the allergic risk of food proteins makes it necessary to implement a policy of allergy vigilance for novel foods. Studies concerning the allergic risk for lupin flour, a new ingredient used in baked goods, are given as an example. They indicate the frequency of sensitization and cross peanut-lupin flour allergy, the low reactive threshold, indicating the risk of the level of incorporation presently allowed. They make possible current screening for this allergy in the population. Allergy vigilance is a recent concept that aims to set up surveillance of food allergy risks in a manner analogous to that of pharmacovigilance for drugs. A project for creating such a structure is being discussed. Although the central structure remains at the initiative of the Agence Française de Sécurité Sanitaire de l'Alimentation (French Agency for Food Safety) and the Institut de Veille Sanitaire (Institute of Health) the authors specify what a peripheral network of allergists should be, analyze the desired content of the bi-directional flow of information, and propose envisaging an intermediate regulatory organization, specialized in the diagnosis and treatment of food allergies. The ongoing idea is that environmental

    2016-01-01

    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.

  5. Radioassay in allergy and immunology

    International Nuclear Information System (INIS)

    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

    We describe 14 consecutive patients with complaints due to the handling of flowers. The symptoms varied from allergic rhinoconjunctivitis and asthma to urticaria. Most patients had professions in the flower industry. Skin prick tests (SPT) were performed with home-made pollen extracts from 17 different flowers known to be the most commonly grown and sold in The Netherlands RAST against mugwort, chrysanthemum, and solidago was performed. The diagnosis of atopy against flowers was based on work-related symptoms due to the handling of flowers, positive SPT with flower extracts, and positive RAST. The concordance between SPT and case history was 74%, and that between SPT and RAST was 77% Extensive cross-sensitization was seen to pollen of several members of the Compositae family (e.g., Matricaria, chrysanthemum, solidago) and to pollen of the Amaryllidaceae family (Alstroemeria and Narcissus). Homemade flower extracts can be used to confirm IgE-mediated flower allergy. Mugwort can be used as a screening test for possible flower allergy. For most patients, the allergy led to a change of profession. PMID:9534922

  7. Toxocariasis Resulting in Seeming Allergy

    Directory of Open Access Journals (Sweden)

    Rosanna Qualizza

    2009-09-01

    Full Text Available Toxocara canis is an intestinal nematode affecting dogs and cats that causes human infestations by ingestion of embryonated eggs excreted in dogs' faeces. Humans are transport hosts, in whom the larvae do not develop to adult worms, but may migrate to various tissues and organs, and survive for several years, giving rise to several clinical symptoms, which include allergy-like presentations. We report three cases presenting as dermatitis, rhinitis, asthma, and conjunctivitis which were diagnosed and unsuccessfully treated as allergy. The correct diagnosis was established after detecting anti-Toxocara antibodies by Western blotting. All clinical symptoms showed improvement after starting treatment with mebendazole and subsequent courses of the antiparasitic drug resulted in full recovery. This suggests the possible role of Toxocara canis in inducing chronic symptoms of allergic type. This is particularly important for asthma, where it has been demonstrated that Toxocara canis infection causes allergic inflammation in the lungs associated with bronchial hyperreactivity. On the other hand, in our patients with asthma and with dermatitis the positive results from allergy tests were a confounding factor in delaying the correct diagnosis, which was finally obtained by the detection of antibodies to Toxocara canis.

  8. Oral allergy syndrome in children.

    Science.gov (United States)

    Ivković-Jureković, Irena

    2015-06-01

    Oral allergy syndrome (OAS) is an allergic reaction that occurs after consumption of fresh fruits and vegetables in patients with allergy to pollen. It is mediated by immunoglobulin E (IgE) antibodies and symptoms arise as a result of cross-reactivity between pollen and plant-derived food. OAS is rarely seen in young children, but the prevalence increases with age. The objectives of the study were to identify the prevalence of OAS and probable risk factors in children and adolescents with seasonal allergic rhinitis (AR). One-hundred and twenty patients with seasonal AR were included. Patients were diagnosed based on their clinical history, skin prick test outcome and specific IgE. In patients describing OAS, prick-by-prick tests with fresh fruit or vegetables were carried out. Thirty-two patients had OAS and it was more frequent in female patients than in male patients. OAS was more frequent in adolescents than in small children and in patients with higher total IgE. OAS was significantly more prevalent in patients with AR and asthma (P=0.0016), as was the case in patients with AR and atopic dermatitis (P=0.0004). OAS is rarely diagnosed in small children, partly because of an inadequate clinical history. Patients with OAS may have some risk factors in addition to pollen allergy, and those with more severe atopy are more likely to develop OAS. PMID:25819922

  9. Microbiome/microbiota and allergies.

    Science.gov (United States)

    Inoue, Yuzaburo; Shimojo, Naoki

    2015-01-01

    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.

Italian pizza found its origin in Napoli and only in recent years has become a very popular food in the rest of Italy and elsewhere. In the beginning, it was the food of the poor, but was made with natural foods, but nowadays has been enriched by a number of ingredients and flavourings, thus multiplying the risk of allergic reactions.

  19. Developmental trajectories in food allergy: a review.

    LENUS (Irish Health Repository)

    DunnGalvin, A

    2009-01-01

    Increasing recognition of the importance of the relationships between perceptions, emotions, behaviors and health has changed the way health and disease are portrayed and researched. A chronic condition may affect and\\/or interact with already existing normative demands and changes in socialization. Although the prevalence of food allergy and anaphylaxis have been reportedly increasing, the emotional and social impact of growing up with food allergy has received little emphasis. In this paper, we present current findings on the biopsychosocial impact of food allergy on children in order to gain insight into the food allergy experience, from the perspective of the child, teen, and parent living with food allergy, with particular attention to developmental aspects. Due to the scarcity of publications on the psychosocial dimensions of food allergy, we also draw on selected literature on children\\'s and parent\\'s experience of, and coping with chronic disease that may inform research into food allergy. To this end, we review some general developmental mechanisms that may underpin and explain normative age-graded shifts in patterns of coping across childhood and adolescence. We also highlight gaps in the literature and assess implications of current research in food allergy and other chronic diseases for intervention and prevention of negative short and long term outcomes.

    OBJECTIVE: The primary objective of this review is to discuss the clinical features, diagnosis, natural history, and prognosis of cow's milk allergy in early childhood and its relationship to development of inhalant allergies. DATA SOURCES: A review of 229 PubMed (National Library of Medicine...... in up to 50% and allergy against inhalants in 50 to 80% before puberty. CONCLUSIONS: CMPA is the most common food allergy in early childhood with an incidence of 2 to 3% in the first year of life. The overall prognosis of CMPA in infancy is good with a remission rate of approximately 85 to 90%. In...... particular, gastrointestinal symptoms show a good prognosis. An early increased immunoglobulin E-response to CMP is associated with an increased risk of persistent allergy to CMP, development of adverse reactions to other foods, and development of asthma and rhinoconjunctivitis later in childhood....

  1. Future therapeutic options in food allergy.

    Eigenmann, P A

    2003-12-01

    Up to 5% of young children and 2% of adults suffer from food allergy. Among them many have immunoglobulin E (IgE)-mediated food allergy, a condition with potentially fatal allergic reactions. Several studies have addressed possible definite treatment options for food allergy. Immunotherapy, by the oral route or by systemic injections shows promising preliminary results, but current interpretation of these therapeutic options are mostly handicapped by studies with insufficient scientific support, or by severe side-effects. Currently, no studies can support pharmacotherapy. Finally, most promising results were recently published with anti-IgE antibodies in a human trial, or various approaches in a mouse model of food allergy (chinese herbal medicine, specific modulation of the T cell response). Rapidly evolving findings might provide hope for a cure of food allergy in the near future. PMID:14616094

    2004-11-01

    Up to 6% of young children and 2% of adults suffer from food allergy. Among them many have IgE-mediated food allergy, a condition with potentially fatal allergic reactions. The only proven treatment is avoidance of the offending food, which can be identified using standardised allergic tests. However, several studies have addressed possible definite treatment options for food allergy. Immunotherapy, administered orally or by systemic injections, shows promising preliminary results, but these therapeutics are based on studies with insufficient scientific support, or are associated with a high risk of severe side effects. At present, no studies can support pharmacotherapy. However, promising results were recently published with anti-IgE antibodies in a human trial, and various approaches in a mouse model of food allergy (chinese herbal medicine, specific modulation of the T-cell response). Rapidly evolving findings might provide hope for a cure for food allergy in the near future. PMID:15571483

    6. SUMMERY 6.1 Summery in English Allergic contact dermatitis (ACD) and psoriasis are the two most prevalent skin diseases in the western world. ACD is the clinical manifestation of contact allergy. Contact allergy and psoriasis are both due to inflammatory mechanisms involving the innate and...... adaptive immune system. Psoriasis is conceived to be an autoimmune disease. Recent studies have suggested an inverse relation between contact allergy and autoimmune diseases. The association between contact allergy and psoriasis could reveal mechanistic insights into both inflammatory processes. The...... overall aim of this PhD study was to investigate the association between contact allergy and autoimmune disease, with focus on psoriasis. The work was done in three study parts. Part I Epidemiological studies. Part II Sensitization study and Part III Experimental studies. In part I the association between...

    2011-01-01

    Objectives Natural rubber latex (NRL) contains over 200 proteins of which 13 have been identified as allergens and the cause of type I latex allergy. Health care workers share a high occupational risk for developing latex allergy. Filaggrin null mutations increase the risk of type I sensitizations...... to aeroallergens and it is possible that filaggrin null mutations also increase the risk of latex allergy. The aim of this paper was to examine the association between filaggrin null mutations and type I latex allergy. Methods Twenty latex allergic and 24 non-latex allergic dentists and dental...... assistants, occupationally exposed to latex, were genotyped for filaggrin null mutations R501X and 2282del4. Latex allergy was determined by a positive reaction or a historical positive reaction to a skin prick test with NRL. Results 41 individuals were successfully genotyped. Three individuals were...

  5. SULFA ALLERGY: CROSS-REACTIVITY VERSUS MULTIPLE CONCURRENT ALLERGIES

    Directory of Open Access Journals (Sweden)

    Muhammad Tariq Shakoor

    2013-01-01

    Full Text Available As a medical resident we have always been taught that there is some sort of cross reactivity between sulfonamide antibiotics and nonantibiotic sulfonamides. Even the manufacturer’s package inserts contain a precautionary statement about possible Cross-reactivity. The most common approach to this problem is avoidance of all sulfa containing drugs. However, there are few data supporting this contraindication. Thus we may be withholding appropriate therapies from patients unnecessarily. To provide a critical and comprehensive review of literature to explore either cross reactivity between sulfonamide antibiotics and nonantibiotic sulfonamides is a fact or fiction and to present an approach to use nonantibiotic sulfonamides in sulfa allergic patients. A PubMed and general medline search was conducted using the individual names of nonantibiotic sulfonamides. We reviewed all of the available case reports and studies regarding sulfonamide antibiotic cross-reactivity with nonantibiotic sulfonamides. Also reviewed the manufacturer’s package insert for each nonantibiotic sulfonamide drug for information concerning possible cross-reactivity with sulfonamide antibiotics. Sulfa drug allergy is one word holding the whole cross-reactivity theory in it. It should be obsolete from the medical dictionary. This one word is complicating the medical decision-making. Allergies should not be attributed to classes or groups of drugs unless proven. After reviewing all the available literature we can conclude that assumptions about cross-reactivity are a FICTION.

  6. Contact allergy to toothpaste flavors

    DEFF Research Database (Denmark)

    Andersen, Klaus Ejner

    1978-01-01

    reactions are rare due to several reasons; local factors in the mouth, the low sensitizing potential of the flavors generally used, and the lack of recognition. It is emphasized that the toothpaste battery for patch testing has to be relevant and changed according to the consumers' and manufacturers' taste......Toothpaste flavors are fragrance mixtures. Oil of peppermint and spearmint, carvone and anethole are ingredients with a low sensitizing potential, but they are used in almost every brand of toothpaste and caused seven cases of contact allergy in a 6-year period at Gentofte Hospital.

  7. Allergy associated with Paterson's Curse.

    Science.gov (United States)

    Burdon, J J; Burdon, J G

    1983-07-23

    A case of allergic rhinitis which occurred on exposure to Paterson's Curse (Echium plantagineum) is described. Symptoms developed on exposure both to flowering and to dead, dried plants. Inhalational challenge tests with pure preparations of pollen and epidermal debris, including plant hairs, resulted in the symptoms and signs of allergic rhinitis. Field experiments in a large natural stand of Paterson's curse showed that pollen and particulate plant debris, including plant hairs, were airborne during the flowering season. These findings indicate that pollen, epidermal hairs, and particulate matter cause allergic symptoms in susceptible subjects, and suggest that allergies to Paterson's Curse may be encountered beyond the main flowering period.

    Vionnet, Julien; Petitpierre, Stéphanie; Fumeaux, Alexandre; Meuli, Reto; Spertini, Francois; Comte, Denis

    2013-04-17

    Allergy to radiographic contrast media Hypersensitivity reactions to radio-contrast media are common in the daily practice. These products are responsible for immediate ( 1 hour after administration) hypersensitivity reactions. A diagnostic work-up by an allergologist with skin tests and in some cases provocation tests is of value in reducing the risk of recurrent hypersensitivity reactions to iodinated contrast media. A careful selection of the patients is required because the incidence of breakthrough reactions is still concerning, even with proper premedication. Practical recommendations are presented in this article. For gadolinium-based contrast agents, data in the literature is not sufficient for suggesting guidelines. PMID:23667970

    2016-05-01

    Cow’s Milk Protein Allergy (CMPA) is the most common food allergy in early childhood in the developed world next to egg allergy. The prevalence is estimated at three to seven per cent, with a resolution rate of 80 to 90 per cent at six years. Accurate diagnosis rests on a good clear allergy focused history.

  11. Triticale allergy in a farmer.

    Science.gov (United States)

    Merget, Rolf; Sander, Ingrid; van Kampen, Vera; Raulf, Monika; Brüning, Thomas

    2016-06-01

    We present the case of a 29-year-old farmer with hay fever and atopic dermatitis since adolescence who had developed work-related asthma about 5 years earlier. He was sensitized to grass pollen, wheat and rye flour, dust from the floors of the animal facilities (cows and pigs) and grain barn, and a battery of animal feed from his farm. Work-relatedness of his asthma was demonstrated by serial measurements of spirometry and fractional exhaled nitric oxide at work and during a holiday. Immunoblot analyses revealed dominant IgE-binding to grass pollen and triticale (a hybrid of rye and wheat). IgE inhibition experiments demonstrated that sensitization to triticale was not due to cross-reactivity to grass pollen. Testing of specific IgE-antibodies to recombinant wheat allergens showed sensitizations to profilin, peroxidase, and nonspecific lipid transfer proteins type I subfamily 9.1 and 9.7. We conclude that triticale allergy may occur as a distinct allergy in farmers. Am. J. Ind. Med. 59:501-505, 2016. © 2016 Wiley Periodicals, Inc. PMID:26814013

  12. Climate change, environment and allergy.

    Science.gov (United States)

    Behrendt, Heidrun; Ring, Johannes

    2012-01-01

    Climate change with global warming is a physicometeorological fact that, among other aspects, will also affect human health. Apart from cardiovascular and infectious diseases, allergies seem to be at the forefront of the sequelae of climate change. By increasing temperature and concomitant increased CO(2) concentration, plant growth is affected in various ways leading to prolonged pollination periods in the northern hemisphere, as well as to the appearance of neophytes with allergenic properties, e.g. Ambrosia artemisiifolia (ragweed), in Central Europe. Because of the effects of environmental pollutants, which do not only act as irritants to skin and mucous membranes, allergen carriers such as pollen can be altered in the atmosphere and release allergens leading to allergen-containing aerosols in the ambient air. Pollen has been shown not only to be an allergen carrier, but also to release highly active lipid mediators (pollen-associated lipid mediators), which have proinflammatory and immunomodulating effects enhancing the initiation of allergy. Through the effects of climate change in the future, plant growth may be influenced in a way that more, new and altered pollens are produced, which may affect humans. PMID:22433365

  13. Prevalence of food allergy: an overview.

    Science.gov (United States)

    Madsen, Charlotte

    2005-11-01

    At present the only cure for food allergy is to avoid eating the food responsible for the allergy. Thus, food allergy or food hypersensitivity is a disease that is not only of concern to the individual who is affected but also to those involved directly and indirectly in supplying and preparing food for the food-allergic individual, and its impact on society should be evaluated on this basis. It is generally assumed that questionnaire-based studies vastly overestimate the prevalence of food hypersensitivity. The reported perceived prevalence of food hypersensitivity varies from 3.24% to 34.9%, which may be explained partly by the difference in reporting lifetime prevalence compared with point prevalence. However, of more importance is the apparent inverse correlation between response rate and prevalence (the higher the response rate, the lower the perceived prevalence). The three most-recent prevalence studies on food hypersensitivity (one on perceived food hypersensitivity and two on confirmed food hypersensitivity) all report estimates for prevalence of approximately 3%, but their criteria for including subjects as being positive are not identical, although they do overlap. Furthermore, because of differences in methodology there is no definitive information to indicate whether the prevalence of food allergy is increasing. However, the high prevalence of pollen-related food allergy in younger adults in the population suggests that the increase in pollen allergy is also being accompanied by an increase in pollen-related food allergy.

    2014-01-01

    Food allergy can have significant effects on morbidity and quality of life and can be costly in terms of medical visits and treatments. There is therefore considerable interest in generating efficient approaches that may reduce the risk of developing food allergy. This guideline has been prepared...... by the European Academy of Allergy and Clinical Immunology's (EAACI) Taskforce on Prevention and is part of the EAACI Guidelines for Food Allergy and Anaphylaxis. It aims to provide evidence-based recommendations for primary prevention of food allergy. A wide range of antenatal, perinatal, neonatal......, and childhood strategies were identified and their effectiveness assessed and synthesized in a systematic review. Based on this evidence, families can be provided with evidence-based advice about preventing food allergy, particularly for infants at high risk for development of allergic disease. The...

    1984-03-16

    p6 report two cases of cutaneous allergy to human (recombinant DNA) insulin. Each patient had a history of systemic allergic reactions to porcine insulin and was at least as reactive to human as to porcine insulin by end-point cutaneous titration. Both patients' insulin allergy was managed with animal insulins and both have done well. Our experience with these two patients indicates that human insulin (rDNA) should not be expected to be efficacious in all patients with systemic allergy to insulin. PMID:6366262

    Food allergy represents an increasing concern to society. It is defined as an inappropriate immunological reaction to normally harmless food components and affects 5-8% of children and 1-2% of adults. Since at the time of writing no cure for food allergy exists, food allergic consumers need to avoid all problematic foods and ingredients, which may have a negative impact on the quality of life and economic functioning of food allergic consumers and their families.

  6. [Immunological background and pathomechanisms of food allergies].

    Science.gov (United States)

    Schülke, Stefan; Scheurer, Stephan

    2016-06-01

    Recent advances in immunology have greatly improved our understanding of the pathomechanisms of food allergies. Food allergies are caused and maintained by complex interactions of the innate and adaptive immune system involving antigen-presenting cells (APC), T cells, group 2 innate lymphoid cells (ILC2), epithelial cells (EC) and effectors cells. Additionally, epigenetic factors, the intestinal microbiome and nutritional factors modulating the gastrointestinal lymphatic tissue probably have a significant impact on allergy development. However, why certain individuals develop tolerance while others mount allergic responses, the factors defining the allergenicity of food proteins, as well as the immunological mechanisms triggering allergy development have yet to be analyzed in detail.

Of those patients, 39.8% had a specific allergen identified and 22.7% had allergic reaction characteristics documented. Variation between PCPs was greater than would be expected by chance (all p<0.001 in the percentage of their patients with a documented beta-lactam allergy (7.9% to 24.8%, identification of a specific allergen (e.g. amoxicillin as opposed to "penicillins" (24.0% to 58.2% and documentation of the reaction characteristics (5.4% to 51.9%.

    Flokstra-de Blok, B M J; Dubois, A E J

    2012-07-01

    Food allergy has become an emerging health problem in Western societies. Although food allergy is characterized by a relatively low mortality and an almost continual absence of physical symptoms, food allergic patients are continually confronted with the possibility of potentially severe reactions and the necessity of dietary vigilance. Health-related quality of life (HRQL) may be the only meaningful outcome measure available for food allergy measuring this continuous burden. HRQL may be measured with generic or disease-specific instruments. Generic instruments may be relatively unresponsive to differences or changes in health status, whereas disease-specific instruments are generally more sensitive for relatively subtle problems related to a particular illness. Recently, a number of disease-specific questionnaires have become available to measure the HRQL of food allergic patients. An important area for further research is the interpretation of the outcome of HRQL measures. In this respect, the minimal clinically important difference (MCID) is of special interest. In combination with the numbers needed to treat (NNT), this may give an ultimate insight into the clinical relevance of an intervention. Since there is still no cure for food allergy, the only available treatment is strict avoidance of the culprit food and provision of emergency treatment. The double-blind placebo-controlled food challenge (DBPCFC) is considered to be the gold standard for diagnosing food allergy. A number of studies have investigated the perceptions of parents whose children underwent a DBPCFC. In contrast to the parental perception, there is much currently still unknown about the effects of undergoing a DBPCFC in the perceptions of patients. In addition to the research on MCID and NNT of food allergy HRQL questionnaires, further research should focus on deriving quality-adjusted life years (QALYs) from food allergy HRQL questionnaires and the application of food allergy HRQL

  16. Intrauterine immunology in allergy and infection

    OpenAIRE

    Pregnancy is interesting from an immunological point of view. The maternal immune system has to tolerate the fetus and at the same time also protect against infection. The placenta is not a completely tight barrier: in fact, cells can pass through in both directions. Allergy often starts early in life and intrauterine factors have been proposed to play a role in development of allergy. The overall aim of this thesis was to study the innate response to infection and the p...

  1. Diagnosing and managing peanut allergy in children.

    Science.gov (United States)

    Tibbott, Rebecca; Clark, Andrew

    2014-06-01

    The prevalence of peanut allergy is thought to be rising with 1 in 70 children affected in the UK. Accidental exposures are frequent and nut allergies are the leading cause of fatal food allergic reactions. Allergic reactions to peanuts are nearly always an immediate, type 1-mediated hypersensitivity response. The typical physiological response associated with such a reaction includes smooth muscle contraction, mucous secretion and vasodilatation. These responses are typically rapid in onset and can lead to systemic effects i.e. anaphylaxis. Peanut allergy most commonly presents in the first five years of life. More than 90% of nut allergic children will have a history of eczema, asthma, rhinitis or another food allergy. The clinical diagnosis of peanut allergy is made from a typical history in combination with clinical evidence of sensitisation i.e. the presence of peanut-specific IgE or positive skin prick tests. There are several predictors of future severe reactions, including: poorly controlled asthma, multiple allergies and previous severe reactions. The amount of peanut consumed is likely to be the major determinant of severity. Management includes a comprehensive package of allergen avoidance advice, provision of emergency medication, family and school/nursery training. The mainstay of management is advice on allergen avoidance. Verbal and written advice should be given. Fast-acting antihistamines as well as adrenaline autoinjectors should be provided as appropriate. Undertreated asthma is a known risk factor for severe reactions and therefore patients with co-existent asthma should undergo regular review. PMID:25102573

  2. [Food allergy in dog and cat].

    Science.gov (United States)

    Vroom, M W

    1994-10-15

    Food allergy in the dog or cat can only be described as non-seasonal dermatitis accompanied by scratching. When the term 'food allergy' is used, an immune-mediated reaction is not always meant, although the term would suggest that it is. The frequency of occurrence of food allergy is unknown, with the literature giving widely differing percentages. Type I and type IV hypersensitivity reactions probably play a role in the pathogenesis, although a type III reaction is also thought to be involved. Gastrointestinal disturbances and skin complaints are symptoms of food allergy, and scratching is nearly always mentioned as the most common sign. The diagnosis can only be made by feeding the animal on a hypoallergic diet, which must be given for several weeks. Diagnostic tests are unreliable. The patient should not have been previously exposed to the ingredients of the hypoallergic diet. As 'home-made' diets may be deficient in minerals, vitamins, and essential amino acids, these ingredients must be supplemented if the diet is to be maintained for a long time. The prognosis of food allergy is good if the causative ingredient is identified. It is important the animals' owner is given through instruction. Medicines have little effect on food allergy.

    Full Text Available Allergy to wheat is a common food allergy. In spite of this fact, there is not enough literature regarding the features and outgrowing of this allergy. The objective of this study was to evaluate the manifestations of this allergy and to follow the patients to evaluate whether outgrowing allergy happens again and when it occurs.Eight wheat allergic patients diagnosed between 2000 and 2001 were re-evaluated together  with 13 other  new cases of  wheat allergy referred to  the  Immunology and Allergy Pediatric  Department   from  June  2004  to  March  2006.  For  all  cases,  the demographic data along with a complete history regarding allergy to wheat and other types of allergy were collected in questionnaires. The specific IgE measurements (in vivo and in vitro and oral food challenge (in the absence of a relevant history related to allergy to wheat were performed.Severe anaphylaxis was seen after wheat ingestion in more than 90% of the patients. Oral tolerance to wheat developed in three patients (37.5% out of 8 known previous cases who had been followed for eight years, the mean age of oral tolerance to wheat was 68±6.36 (range; 36 months to 108 months.Clinical reactions in our wheat-allergic patients were more severe than those reported before. These patients were at risk for developing chronic allergic symptoms such as asthma. We also found that oral tolerance to wheat was happening in a minority of our patients.

  10. Antibiotic allergy in cystic fibrosis.

    Science.gov (United States)

    Parmar, J S; Nasser, S

    2005-06-01

    Allergic reactions to antibiotics are more common in cystic fibrosis (CF) than in the general population. This in part is due to the improving survival in adults with CF and the increased use of high dose intravenous antibiotics. While some are immediate anaphylaxis type (IgE mediated) reactions, the majority are late onset and may have non-specific features such as rash and fever. Piperacillin has consistently been found to have the highest rate of reported reactions (30-50%). There is a low risk of cross reactions between penicillins and other non-beta-lactam classes of antibiotics in penicillin skin prick positive patients. Carbapenems should only be used with extreme caution in patients with positive skin prick tests to penicillin. However, aztreonam can be used safely in patients who are penicillin allergic with positive skin prick reactions. The aminoglycosides are a relatively uncommon cause of allergic reactions, but patients who react to one member of the family may cross react with other aminoglycosides. Desensitisation relies on the incremental introduction of small quantities of the allergen and has been used for penicillins, ceftazidime, tobramycin and ciprofloxacin and must be repeated before each course. Personalized cards should be regularly updated for patients who develop allergic reactions. Written instructions on the emergency treatment of allergic reactions should be provided to patients self-administering intravenous antibiotics at home. Further research is required to identify risk factors and predictors for antibiotic allergy. PMID:15923254

    2015-10-01

    Food allergy is a growing concern, and recognition of symptoms, knowledge of common food allergens, and management of reactions are important for patients and practitioners. Symptoms of a classic IgE-mediated food allergy vary in severity and can include any combination of laryngeal edema, wheezing, nausea, vomiting, diarrhea, urticaria, angioedema, and hypotension. Many foods can induce an allergic reaction, but the most commonly implicated foods include cow's milk, egg, peanut, tree nut, soy, wheat, fish, and shellfish. Milk and egg allergy generally develop and are outgrown in childhood. Peanut and tree nut allergy can occur during childhood or adulthood, are less likely to be outgrown, and tend to cause more fatal reactions. Given the possibility of life-threatening reactions, it is important to recognize the potential for cross-reactivity among food groups. Diagnosis of food allergy includes skin prick testing, specific serum IgE testing, and oral food challenges. Management is centered on avoidance of allergenic and cross-reacting foods and early recognition and immediate treatment of reactions. Treatment protocols to desensitize patients to food are currently under investigation. PMID:26434966

    Contact allergy is frequent among dermatitis patients and subjects in the general population. This review aims to update the reader on the epidemiology of contact allergy epidemics. It presents recent epidemiological data on metals, fragrances, hair dyes, preservatives and thiurams. It concludes that the prevalence of nickel allergy is decreasing among young women whereas the prevalence of cobalt allergy remains stable. The prevalence of chromium allergy is currently increasing significantly in both sexes, mainly as a result of leather exposure. The epidemiology of fragrance allergy is changing as the prevalence of fragrance mix I and myroxylon pereirae allergy has decreased significantly in recent years and as the prevalence of fragrance mix II allergy has increased. The prevalence of p-phenylenediamine allergy seems stable in Europe but remains high. The prevalence of isothiazolinone allergy remains high whereas the prevalence of methyldibromo glutaronitrile allergy has decreased following regulatory intervention. Finally, the prevalence of thiuram allergy is decreasing as a result of improved rubber glove production. PMID:19834429

    2016-02-01

    Because the role of eosinophils in neonates is not well understood, the clinical significance of eosinophilia in neonates is unclear. We encountered a rare case of cow's milk allergy in a premature male infant with severe eosinophilia in the neonatal period. The peripheral blood eosinophil count in this infant was 7,404/μL at birth, and he produced stools with fresh blood immediately after birth and prior to the first feedings with regular cow's milk. Although the patient's eosinophil count normalized without specific treatment within 6 weeks after birth, it is possible that the causes of the eosinophilia in this infant prior to the first feedings with regular cow's milk were different from those after the first feedings. Cow's milk allergy was diagnosed on the basis of the patient's positivity for this allergy in the challenge test and subsequent allergen-specific lymphocyte stimulation test performed at 6 months of age.

    The prevalence of food allergy is increasing worldwide and is an important cause of anaphylaxis. There are no local South African food allergy guidelines. This document was devised by the Allergy Society of South Africa (ALLSA), the South African Gastroenterology Society (SAGES) and the Association for Dietetics in South Africa (ADSA). Subjects may have reactions to more than one food, and different types and severity of reactions to different foods may coexist in one individual. A detailed history directed at identifying the type and severity of possible reactions is essential for every food allergen under consideration. Skin-prick tests and specific immunoglobulin E (IgE) (ImmunoCAP) tests prove IgE sensitisation rather than clinical reactivity. The magnitude of sensitisation combined with the history may be sufficient to ascribe causality, but where this is not possible an incremental oral food challenge may be required to assess tolerance or clinical allergy. For milder non-IgE-mediated conditions a diagnostic elimination diet may be followed with food re-introduction at home to assess causality. The primary therapy for food allergy is strict avoidance of the offending food/s, taking into account nutritional status and provision of alternative sources of nutrients. Acute management of severe reactions requires prompt intramuscular administration of adrenaline 0.01 mg/kg and basic resuscitation. Adjunctive therapy includes antihistamines, bronchodilators and corticosteroids. Subjects with food allergy require risk assessment and those at increased risk for future severe reactions require the implementation of risk-reduction strategies, including education of the patient, families and all caregivers (including teachers), the provision of a written emergency action plan, a MedicAlert necklace or bracelet and injectable adrenaline (preferably via auto-injector) where necessary.

    Milk has been recognized as a leading cause of food allergy in children; however, studies on cow’s milk allergy (CMA) in adults are scanty. The known cross-reactivity of bovine serum albumin and bovine γ-globulin which are present in both milk and beef is recognized, so that, patients with allergy to cow’s milk are often instructed to avoid beef. Our Objective was to determine the prevalence of allergy to beef meat in adult patients with allergy to cow’s milk. Thirty adults with CMA were incl...

    1993-07-15

    The diagnosis of food allergy was confirmed in 51 dogs while the responsiveness to a 60-day home-cooked restricted dietary trial (elimination-diet trial) was evaluated. The primary clinical sign of allergy detected and evaluated in all dogs was persistent and nonseasonally pruritic skin disease. The duration of time between starting the elimination-diet trial and remission of clinical signs was recorded. Dogs were then reexposed to diets that had been fed before testing, and the duration of time before pruritus recurred was recorded. The elapsed time during which dogs were being fed an elimination diet before remission of clinical signs was 1 to 3 weeks in 13 dogs, 4 to 6 weeks in 25 dogs, 7 to 8 weeks in 10 dogs, and 9 to 10 weeks in 3 dogs. Findings indicated that the recommendation of a 3-week elimination-diet trial for diagnosis of food allergy was adequate for only 25% of the dogs. It is recommended that test diets be fed for at least 10 weeks before a food allergy is ruled out. PMID:8407485

    The human microbiome can be defined as the microorganisms that reside within and on our bodies and how they interact with the environment. Recent research suggests that numerous mutually beneficial interactions occur between a human and their microbiome, including those that are essential for good health. Modern microbiological detection techniques have contributed to new knowledge about microorganisms in their human environment. These findings reveal that the microbiomes of the lung and gut contribute to the pathogenesis of asthma and allergy. For example, evidence indicates that the microbiome of the gut regulates the activities of helper T cell subsets (Th1 and Th2) that affect the development of immune tolerance. Moreover, recent studies demonstrate differences between the lung microbiomes of healthy and asthmatic subjects. The hygiene and biodiversity hypotheses explain how exposure to microorganisms is associated with asthma and allergy. Although those living in developed countries are exposed to fewer and less diverse microorganisms compared with the inhabitants of developing countries, they are experiencing an increase in the incidence of asthma and allergies. Detailed analyses of the human microbiome, as are being conducted under the auspices of the Human Microbiome Project initiated in 2007, promise to contribute insights into the mechanisms and factors that cause asthma and allergy that may lead to the development of strategies to prevent and treat these diseases.

    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.

    Full Text Available Chemical allergy is of considerable importance to the toxicologist, who, amongst other things, has the responsibility of identifying and characterizing the skin (and respiratory sensitizing potential of chemicals, and estimating the risk they pose to human health. Allergic contact dermatitis (ACD is to a large extent a preventable disease. Although quantitative risk assessment (QRA for contact allergy can be performed, it is reasonable to ask why the burden of the skin disease ACD appears to remain stubbornly high, and in particular, that the general level of ACD to sensitizing ingredients found in cosmetics has not fallen noticeably over recent decades; some could argue that it has increased. In this review, this conundrum is addressed, considering whether and to what extent the prevalence of cosmetic allergy is truly unchanged, whether the predicted test methods and potency estimations are sufficiently precise and how proposed changes to the QRA process (i.e., cumulative exposure may ameliorate the situation. Improved and more widespread use of risk assessment, better education of risk assessors, better post-marketing surveillance and monitoring of dermatology clinic feedback to improve QRA, all together could help to “make contact allergy history”.

    Rolland, J M; O'Hehir, R E

    2008-06-01

    Allergy to natural rubber latex products emerged as an important clinical condition following an increase in the use of latex gloves for barrier protection in the early 1980s. In addition to latex glove users, other high-risk groups with different latex exposure include spina bifida patients and others with multiple surgical procedures. Subjects with fruit and vegetable allergy are also at risk due to cross-reactive allergens. Following the significant advances in the identification and characterization of common aeroallergens, latex allergy was well placed to become an excellent model of therapy. Awareness of latex allergy and modes of sensitization enabled epidemiological studies to inform allergen avoidance initiatives, substantially reducing inadvertent exposure in major hospitals in Western countries. Spina bifida is often identified in utero or soon after birth, allowing vigorous latex allergen avoidance with enhanced efficacy of primary prevention. However, changing demographics of latex allergy and technological revolution in countries such as China and India are predicted to unleash a second wave of latex allergy reemphasizing the incentive for improved manufacturing procedures for latex products. The desirable high tensile strength and elasticity of natural rubber latex have made the commercial identification of good alternatives very difficult but this would also be attractive for primary prevention. In addition, an effective specific immunotherapy regimen would be valuable for selected high-risk atopic individuals. Current subcutaneous and sublingual immunotherapy schedules have been tested for treatment of latex allergy with evidence of efficacy but the risks of adverse events are high. For such potent allergens as latex, hypoallergenic but T cell-reactive preparations are required for clinical use. Identification of allergenic components of latex products, with generation of monoclonal antibodies and recombinant allergens, allowed sequence

    Full Text Available Abstract Background Allergy is a serious and apparently increasing public health problem yet relatively little is known about the types of allergy seen in routine tertiary practice, including their spatial distribution, co-occurrence or referral patterns. This study reviewed referrals over an eleven year period to a regional allergy clinic that had a well defined geographical boundary. For those patients confirmed as having an allergy we explored: (i differences over time and by demographics, (ii types of allergy, (iii co-occurrence, and (iv spatial distributions. Methods Data were extracted from consultant letters to GPs, from September 1998 to September 2009, for patients confirmed as having an allergy. Other data included referral statistics and population data by postcode. Simple descriptive analysis was used to describe types of allergy. We calculated 11 year standardised morbidity ratios for postcode districts and checked for spatial clustering. We present maps showing 11 year rates by postcode, and 'difference' maps which try to separate referral effect from possible environmental effect. Results Of 5778 referrals, 961 patients were diagnosed with an allergy. These were referred by a total of 672 different GPs. There were marked differences in referral patterns between GP practices and also individual GPs. The mean age of patients was 35 and there were considerably more females (65% than males. Airborne allergies were the most frequent (623, and there were very high rates of co-occurrence of pollen, house dust mite, and animal hair allergies. Less than half (410 patients had a food allergy, with nuts, fruit, and seafood being the most common allergens. Fifteen percent (142 had both a food and a non-food allergy. Certain food allergies were more likely to co-occur, for example, patients allergic to dairy products were more likely to be allergic to egg. There were age differences by types of allergy; people referred with food allergies were

    Full Text Available  Food allergy is now looming as a major health issue with significant implications. In westernized countries, recent reports show a rise in allergic diseases, in particular food allergy. It affects approximately 5–8�0of children and 1–5�0of adults. Despite this, our current understanding of the immunological and biological mechanisms of food allergy is still incomplete. It is generally believed that food allergy is determined by both genetic and environmental factors. There is some evidence that epigenetic modifications may affect the prevalence of food allergies. This paper discusses the current state of knowledge regarding genetic, epigenetic and environmental factors of food allergy.

    Allergy to natural rubber latex (NRL) has become an important health issue in recent years, but little is known about how this condition is investigated by physicians in the UK. This postal questionnaire of British dermatology and allergy specialists shows substantial variation in diagnostic practice, most notably with regard to the utilization and choice of starting dose of commercial latex prick test dilutions, reliance on allergen-specific immunoglobulin E measurement, investigation of associated fruit allergy and provision of resuscitation equipment/method of consent when challenge testing. 17% of responding physicians who investigate for NRL allergy do not perform prick test or glove challenge because of the potential risk of anaphylaxis or lack of resuscitation facilities. 87% of allergy clinic specialists report no reduction in the number of patients presenting as new referrals with suspected NRL allergy. These findings suggest a need for robust guidance to achieve more consistent investigative practice by those dealing with this condition. PMID:15701123

    2013-07-01

    Full Text Available The reactivity to food proteins is specific, but in certain patients cross reactions are observed between food proteins of plant or animal origin and non-food ones. The most common clinical manifestation of this cross reactivity is oral allergy syndrome (OAS. It develops mainly in patients with pollen allergy after fresh fruit and vegetables consumption. The symptoms are oro-pharyngeal pruritus, papules and vesicles which resemble mouth ulcers on the labial mucosa and labial, palatal and lingual swelling. There may also be a sensation of pharyngeal swelling. The symptoms appear very quickly and may be followed by urticaria or contiguous facial erythema. The progress of this syndrome is due to homology of structural proteins in foods of plant origin and in pollens.

    Full Text Available Cow's Milk Protein Allergy (CMPA is the most common food allergy in early childhood. It affects between 2% and 3% of infants. Symptoms and signs related to CMPA which IgE-mediated or non IgE-mediated may involve many different organ systems. The first and most important step in diagnosis is a thorough medical history. Results of laboratory tests alone are not sufficient to make diagnosis, always need to be considered together with the clinical features. CMPA can occur with multiple immunological mechanisms, therefore the diagnosis chance increases with use of numerous tests together. However, the negative test does not exclude the diagnosis. The gold standards in diagnosis are food elimination and challenge tests. Cow's milk and avoiding the use of its products, it is still considered as the first choice in the treatment of all children with CMPA.

    2008-01-01

    Full Text Available Abstract. Percentage of CD4+CD25hi is increased in children with allergy, and it is independent on their nosology, severity, sensitization and IgE level in blood. FOXP3 expression virtually was not altered. Inhalation of corticosteroids in asthma causes increase of FOXP3 expression that may represent some mechanisms of their therapeutic effects. The amount of Treg’s gradually decrease with age in non-atopic children; they also decrease in atopic ones until 6 years, followed by their subsequent stabilization. Thus, a hypothesis is proposed, that the initial changes of Treg’s in case of allergy comprise a reduction in their functions, and, upon complete or partial compensation of this defect by increasing of cell amounts, a remission is initiated. However, in absence of compensation, acute attacks of allergic disorders are developed. (Med. Immunol., 2008, vol. 10, N 2-3, pp 159-166.

  14. Towards a cure for food allergy.

    Skripak, Justin M; Sampson, Hugh A

    2008-12-01

    Over the past two decades, food allergies have become both more prevalent and long lasting. This burgeoning problem has not been met with any therapeutic options to date, and patients must attempt to avoid known allergenic foods and treat any allergic reactions with 'as-needed' medications. There are a number of promising emerging therapeutic modalities for food allergy, including allergen-specific and allergen non-specific immunotherapeutic approaches. Although the allergen-specific approaches have some distinct differences, they all attempt to induce tolerance by exposing the patient to an allergen via the mucosal route (oral tolerance induction). Allergen non-specific approaches include biologics to suppress free total IgE levels (e.g. anti-IgE antibody) or to induce more general immune suppression (Chinese herbal medication). PMID:18848884

    2002-02-01

    Acute chondritis has a strong predilection for recurrence. Mafenide acetate has been implicated in causing reactions that mimic this condition; however, these hypersensitivity reactions lack fever, fluctuance, and pain. The authors report a case of mafenide acetate allergy presenting as recurrent chondritis in a patient who had previously been treated successfully for this condition. In this patient, the allergic response resolved within 3 days after cessation of mafenide acetate. If unappreciated, it may have led to unnecessary operative intervention. Therefore, auricular edema and erythema, without fever, fluctuance, and pain, must be recognized by surgeons as a possible mafenide acetate allergy and must be considered in the differential diagnosis for patients who present with recurrent acute suppurative chondritis.

    Adverse food reactions, an adverse health effect arising from an immune or nonimmune response that occurs reproducibly on the exposure to a given food, can be divided into toxic and hypersensitivity reactions. When an immunologic mechanism has been shown, hypersensitivity food reactions should be referred to as food allergy that may be IgE- or non-IgE-mediated. Food allergy diagnosis is mainly guided by a correct and accurate history and physical examination, thus leading to prick test and elimination diets. The treatment gold standard is still represented by an elimination diet together with antihistamines and corticosteroid usage in order to reduce the gastrointestinal and potentially life-threatening systemic symptoms. Other treatments are currently under investigation with promising results. PMID:22722444

  7. Moral Considerations in Pediatric Food Allergies

    Directory of Open Access Journals (Sweden)

    2014-04-01

    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.  

  8. The role of RAST in allergy diagnosis

    International Nuclear Information System (INIS)

    For a suitable planning of the RAST and a correct evaluation of RAST findings, some allergological knowledge is required; also, our knowledge as to the possibilities and limitations of this method of investigation is probably still incomplete. Still, the RAST surely is an important practical application of the immunological experience gained during the last few years - it may well be called a milestone in allergy diagnostics. (orig.)

    Full Text Available Background and Design: We aimed to determine the frequency of latex allergy in our hospital and to to evaluate the clinical and demographical features of the cases.Materials and Methods: A detailed questionnaire was administered to healthcare workers by a physician. Skin prick test with latex and patch test with rubber chemicals and a piece of latex glove were performed for all healthcare workers. Latex-specific IgE was measured in serum.Results: The study sample consisted of 36 nurses, 14 doctors, and 50 healthcare workers. While 46 subjects had symptoms, 54 subjects had no symptoms. The relationship of clinical disease with working duration, exposure duration (hour/day, history of atopy, and drug/food allergies was statistically significant. Five nurses and 1 healthcare worker had positive skin prick test. Two of them had positive latex-specific IgE. Positive skin prick test statistically significantly correlated with occupation, working duration, exposure duration (hour/day and positive latex-specific IgE. Two nurses and 2 healthcare workers had positive latex-specific IgE. Two of them had positive skin prick test. Positive latexspecific IgE statistically significantly correlated with working duration, exposure duration, and positive skin prick test. Patch test with a piece of latex glove was negative in all subjects. Three healthcare workers had positive patch test with thiuram-mix, one of them had also positive patch test with mercaptobenzothiazole.Discussion: One of the risk factors for latex allergy is occupations involving frequent exposure to latex products. Latex allergy should be taken into consideration if type I hypersensitivity reactions occur in occupational groups at risk for anaphylactic reaction.

    Buser, Melanie C; Scinicariello, Franco

    2016-03-01

    Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are a class of organic compounds that are persistent in the environment due to their stable carbon-fluorine backbone, which is not susceptible to degradation. Research suggests these chemicals may exert an immunotoxic effect. The aim of this study is to investigate the associations between four PFASs - perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS) - with food sensitization and food allergies in adolescent participants (ages 12-19years) in the National Health and Nutrition Examination Survey (NHANES) 2005-2006 and 2007-2010, respectively. We performed multivariate logistic regression to analyze the association between individual PFASs with food sensitization (defined as having at least 1 food-specific IgE level≥0.35kU/L) in NHANES 2005-2006 and food allergies (self-reported) in NHANES 2007-2010. Serum PFOA, PFOS, and PFHxS were statistically significantly associated with higher odds to have self-reported food allergies in NHANES 2007-2010. When using IgE levels as a marker of food sensitization, we found that serum PFNA was inversely associated with food sensitization (NHANES 2005-2006). In conclusion, we found that serum levels of PFASs were associated with higher odds to have self-reported food allergies. Conversely, adolescents with higher serum PFNA were less likely to be sensitized to food allergens. These results, along with previous studies, warrant further investigation, such as well-designed longitudinal studies. PMID:26722671

    Microarrays and other large-scale screening technologies produce quantities of increasingly complex allergy data. These data link molecular and clinical measurements and observations and provide fertile ground for improving our understanding of the processes involved in allergic reactions. Information technology is employed in gathering, storage, retrieval and analysis of these data. The increasing proportion of allergy data are generated from genomics and proteomics approaches. The major activity focuses on characterization of allergens including IgE reactivity, structural properties, and mapping of IgE and T-cell epitopes. Because of the complexity of allergy data, their utilization requires bioinformatics approaches. Allergen data are stored in the general and specialist databases. At least a dozen of important allergen databases and data repositories have been developed to date. These data are analysed using general and specialist bioinformatics tools. The major applications of bioinformatics include support for allergen characterization, assessment of allergenicity, and identification of allergic cross-reactivity. These applications in turn support the development of vaccines and therapies for allergic disease. In this article we review allergen databases and tools for the analysis of allergens, and discuss the new directions in the field supported by large scale screening involving genomics, proteomics, and bioinformatics support.

AIM: To evaluate effect of multiple antigens up to six in the immunotherapy of nasobronchial allergy. SETTING AND DESIGN: Based on clinical history, symptoms present for at least 3 years with set criteria of immunomodulation for asthma and rhinitis: documented IgE mediated asthma and rhinitis, failure in allergen avoidance and moderate to severe clinical manifestations. MATERIAL AND METHODS: Five hundred cases of various allergic disorders attending allergy clinic of Bombay hospital were screened. Allergen specific immunotherapy was initiated in 131 subjects (56 -rhinitis and 75 asthma with prior consent. Patients suffering from allergic disorders secondary to diseases or drug therapy were excluded. Multiple allergen immunotherapy was given at specific intervals up to a period of one year. Allergen extracts were prepared as per standard technique. For statistical analysis "students′t test" was used. RESULTS AND CONCLUSIONS: Significant improvement in PEFR, reduction in skin sensitivity to allergens used in immunotherapy formulation and symptomatic relief without any untoward reaction show that multiple allergen immunotherapy is as effective as monoallergen immunotherapy in nasobronchial allergy.

  16. Molecular diagnosis of egg allergy: an update.

    2015-01-01

    Hen's egg allergy affects up to 2.5% of young children and is potentially life-threatening. Several phenotypes of egg allergy have been identified, including those who tolerate extensively heated egg in bakery products. Diagnosis and monitoring for resolution often requires oral food challenges, which can result in anaphylaxis. Newer approaches, such as component-resolved diagnostics, microarray analysis and epitope mapping, are being evaluated to determine if these strategies can replace or reduce the need for oral food challenges. Studies suggest that elevated levels of ovomucoid IgE indicate an inability to tolerate extensively heated forms of egg. Egg protein-specific IgE/IgG4 ratios may be helpful in predicting tolerance. Additionally, patients with conformational epitopes to hen's egg are more likely to resolve their allergy compared with those with IgE binding to sequential epitopes. The pairing of microarray technology to epitope mapping is a potential tool to improve diagnosis. This review examines the current body of literature on these tools. PMID:25975845

    2016-05-25

    Hymenoptera venom allergy is an immunoglobulin E (IgE)-mediated hypersensitivity to the venom of insects from the Hymenoptera order and is a common cause of anaphylaxis. A diagnosis of venom allergy is made by taking an accurate medical, family and social history, alongside specific allergy testing. Systemic reactions to Hymenoptera venom occur in a small proportion of the population; these range from mild to life-threatening in severity. Treatment for local reactions involves the use of cold packs, antihistamines, analgesia and topical corticosteroids to help alleviate swelling, pain and pruritus. Venom immunotherapy is the treatment of choice for reducing the incidence of future anaphylactic reactions in individuals who have signs of respiratory obstruction or hypotension. Venom immunotherapy is the most effective treatment in reduction of life-threatening reactions to venom, and can improve quality of life for individuals. Treatment should only be provided by experienced staff who are able to provide emergency care for anaphylaxis and life-threatening episodes. A risk assessment to deliver treatment should be undertaken before treatment is commenced. PMID:27224630

    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 res...

    Cow's milk and hen's egg are ubiquitous in diets around the world and can be important sources of protein in young children. Unfortunately, milk and egg allergies are also some of the most common food allergies in childhood. Less allergenic forms of milk and egg due to heating and interactions with a food matrix, as in baked goods, are tolerated by a majority of milk- and egg-allergic patients. Adding baked milk and egg into the diets of milk- and egg-allergic children can broaden diets, increase nutrition, and improve quality of life. Most important, regular ingestion of baked milk and egg can help children outgrow their allergies to milk and egg. This article will review our current understanding of baked milk and egg tolerance and outline how these baked forms accelerates tolerance to regular milk and egg. PMID:26839628

    2015-09-01

    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. PMID:26442851

    Food allergy continues to be a challenging health problem, with prevalence continuing to increase and anaphylaxis still an unpredictable possibility. While improvements in diagnosis are more accurately identifying affected individuals, treatment options remain limited. The cornerstone of treatment relies on strict avoidance of the offending allergens and education regarding management of allergic reactions. Despite vigilance in avoidance, accidental ingestions and reactions continue to occur. With recent advances in the understanding of humoral and cellular immune responses in food allergy and mechanisms of tolerance, several therapeutic strategies for food allergies are currently being investigated with the hopes of providing a cure or long-term remission from food allergy.

    Lee, Laurie A; Burks, A Wesley

    2009-01-01

    Peanut and/or tree nut allergy is a major health concern affecting over 1% of Americans. Although food allergy in general is the most common cause of anaphylaxis treated in emergency departments, reactions to nuts account for a disproportionate amount of deaths from food allergy. Peanut allergy is a Type I hypersensitivity (IgE mediated) immune response. Eight peanut allergens have been identified that are termed as Ara h 1 through Ara h 8. The diagnosis of peanut allergy can often be made or eliminated with a focused history and specific diagnostic testing. There is no effective method to cure peanut allergy. Therefore, the management of patients with peanut allergy focuses on 1) preventing inadvertent ingestions of peanut, 2) recognizing early signs of allergic reactions, and 3) properly treating peanut-induced symptoms should they occur. Epinephrine is clearly indicated for patients experiencing respiratory, cardiovascular, or neurologic compromise. Because inadvertent ingestion of peanut often leads to life threatening reactions and peanut allergy is often long-lived, many investigators are focusing on decreasing clinical reactivity after peanut allergy is established.

    Tattooing is routinely employed prior to radiotherapy treatment but allergies to tattoos are rare. New information on the incidence of tattoo allergy at St George Hospital is presented with details of two clinical cases. The literature on tattoo allergy has been unable to estimate the incidence of allergic reaction to tattoos because the total number of patients treated is unknown and not all patients were followed up. Our radiation oncology population for the first time has provided a known denominator, but wide confidence intervals prevent an accurate estimate of the incidence. Salient issues about tattoo allergy are highlighted based on a review of the published literature from 1966 to 1998. PMID:10901983

    2014-01-01

    A previous cross-sectional survey highlighted that restaurant staff in Brighton had gaps in their knowledge of food allergy, which could lead to the provision of unsafe meals to food-allergic customers. A food allergy training event was developed by a multi-disciplinary team (health service researcher, clinician, teacher and patient group representative) to equip restaurant staff with the knowledge and skills necessary to safely serve food-allergic customers. This evaluation summarises the training event's impact on participants' knowledge of food allergy and their satisfaction with the event. No attendee had previously attended any formal training on food allergy. The percentage of participants who answered all true-false questions correctly increased from 82% before the training event to 91% afterwards. The percentage of participants who were able to name at least three common allergens increased from 9% to 64%. Both quantitative and qualitative feedback was positive. Restaurant staff require a good understanding of food allergy to ensure that food-allergic customers are kept safe, and their restaurants operate within the law. This food allergy training event improved participants' absolute knowledge of food allergy, and attendees changed practice. Recommendations are made which could improve the impact and uptake of future food allergy training events. PMID:25225607

  20. An overview of fruit allergy and the causative allergens.

    Hassan, A K G; Venkatesh, Y P

    2015-11-01

    Plant allergens, being one of the most widespread allergenic substances, are hard to avoid. Hence, their identification and characterization are of prime importance for the diagnosis and treatment of food allergy. The reported allergies to fruits mainly evoke oral allergy syndrome caused by the presence of cross-reactive IgE to certain pollens and thus, allergy to fruits has also been linked to particular pollens. Many fruit allergies are being studied for their causative allergens, and are being characterized. Some tropical or exotic fruits are responsible for region-specific allergies for which only limited information is available, and generally lack allergen characterization. From a survey of the literature on fruit allergy, it is clear that some common fruits (apple, peach, musk melon, kiwi fruit, cherry, grape, strawberry, banana, custard apple, mango and pomegranate) and their allergens appear to be at the center of current research on food allergy. The present review focuses on common fruits reported as allergenic and their identified allergens; a brief description of allergens from six rare/tropical fruits is also covered. PMID:26549334

  14. [Cow's milk protein allergy through human milk].

    Denis, M; Loras-Duclaux, I; Lachaux, A

    2012-03-01

    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. PMID:22226014

    2015-01-01

    Full Text Available Oral allergy syndrome (OAS is an allergic reaction in the oral cavity subsequent to the consumption of food such as fruits, nuts, and vegetables. It occurs mainly due to homology of proteins of pollen to the proteins of fruits and vegetables. In OAS, the immune system produces antibodies that are directed against the proteins of pollen and structurally similar proteins in food, hence, resulting in allergic symptoms limited mainly to the oral cavity. In this review, we have summarized the etiopathogenesis, clinical features, diagnosis, and management of OAS as an update for stomatologists.

    International Nuclear Information System (INIS)

    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.

  1. Molecular evolution in food allergy diagnosis.

    Science.gov (United States)

    Barocci, Fiorella; DE Amici, Mara; Marseglia, Gian L

    2016-10-01

    Traditional allergological diagnostics often provide laboratory data that seem to correspond with similar positive results in different patients. However, with technological developments and the introduction of molecular diagnostics, it is possible to extract and highlight the differences in the serological laboratory data, to obtain detailed specificity on the various allergen components in different clinical settings. Allergological diagnostics prove to be increasingly useful in accurately distinguishing "cross-reactivity" and "cosensitization". This aspect is very important especially in patients who are, with a traditional diagnosis, polysensitized. Molecular diagnosis in allergology has expanded its range of applications thanks to the ability to IgE dose specific (in addition to classic total IgE serum) not only to allergens, food and inhalants, but also to the individual protein components which make up the allergenic source. It is essential to establish a correct diagnosis in order to determine the appropriate therapy. Therefore it is crucial to discern whether a patient is truly allergic because he presents specific IgE for molecules of a species or if the positivity is given from the structural homology between the different proteins. Molecular diagnostics emerges as a valuable tool for the discrimination of allergic patients and to differentiate between "true allergies" and "cross-reactivity". Molecular diagnostics should be used in a targeted manner for an accurate assessment and diagnosis, which would also reduce the use of oral challenges, to predict severe reactions and allergy persistence.

  2. Food intolerance and allergy--a review.

    Science.gov (United States)

    Lessof, M H

    1983-01-01

    Specific food intolerance needs to be distinguished from obsessional states in which those who are affected have an aversion to numerous foods. Even in cases where specific food intolerance can be demonstrated, the diagnosis of food allergy depends on additional evidence that the patient's reaction is based on an abnormal immunological response. In food allergy, skin and laboratory tests may detect the presence of an IgE-mediated reaction, particularly in patients with asthma or eczema and especially where the foods involved are highly allergenic--such as egg, fish, nuts and milk. However, many patients with proven food intolerance have negative tests, suggesting that other immunological or non-immunological mechanisms are responsible. Laboratory tests for non-IgE reactions are unreliable. Where it is difficult to show a connection between individual foods and an allergic response--as in patients with urticaria provoked by food additives--one of the reasons for diagnostic difficulty is that the offending substances may be present in a wide range of common foods. If the diagnosis is to be firmly established in such cases, it is necessary to show that symptoms remit on an elimination diet and recur after a placebo-controlled challenge. PMID:6351151

  3. Aerobiology and pollen allergy in Islamabad

    International Nuclear Information System (INIS)

    Pollen allergies affect a significant proportion of Islamabad residents. Many patients with pollen allergy Are hospitalized in Islamabad in spring (February to April), fall seasons (July to September) and after monsoons. To determine the type and concentration of airborne pollens causing allergic diseases in the susceptible patients in Islamabad. The study was conducted from January 2005 to December 2006 and Burkard Volumetric Spore Trap' provided by the World Allergy Organization was used. This spore trap was placed in the F-10 area of Islamabad and samples were collected on weekly basis during the whole study period. To obtain the sample, the spore trap drum was loaded with a strip of sticky tape every week. The sampled sticky tape was then collected each week at a specified time and replaced with a fresh strip of sticky tape, which was then collected next week. This cycle , continued for whole study period. From each sample seven permanent slides were made and mounted with gelevitol mounting media; The slides were then examined microscopically. A total of 702 individuals irrespective of age or gender were included in the study. Skin prick tests were performed for pollens using allergen extracts of Hollister-Steir, USA and the results were recorded. The two flowering seasons in Islamabad i.e., spring and fall caused maximum pollen allergies. The Broussonetia papyrifera (paper mulberry) tree in spring, and the Cannabis sativa (bhang) weed in the fall season, Produced the highest seasonal pollen counts. In the spring season of 2005, Broussonetia papyrifera produced the highest pollen count, (73%) of the total pollen count, with a maximum count of 1390 pollen/cu meter of air/hour on 20th of March, while in 2006, it accounted for 75% of the total pollen-count with a maximum count of 1430 pollen/cu meter of air/hour on 10th of March. in fall Season of 2005, Cannabis sativa produced maximum pollen counts of 85 pollens/cu meter of air/hr on 18th of August, while in 2006

    Quirce, Santiago; Boyano-Martínez, Teresa; Díaz-Perales, Araceli

    2016-05-01

    IgE-mediated allergy to wheat proteins can be caused by exposure through ingestion, inhalation, or skin/mucosal contact, and can affect various populations and age groups. Respiratory allergy to wheat proteins is commonly observed in adult patients occupationally exposed to flour, whereas wheat food allergy is more common in children. Wheat allergy is of growing importance for patients with recurrent anaphylaxis, especially when exercise related. The diagnosis of wheat allergy relies on a consistent clinical history, skin prick testing with well-characterized extracts and specific IgE tests. The accuracy of wheat allergy diagnosis may be improved by measuring IgE responses to several wheat components. However, a high degree of heterogeneity has been found in the recognition pattern of allergens among patient groups with different clinical profiles, as well as within each group. Thus, oral provocation with wheat or the implicated cereal is the reference test for the definitive diagnosis of ingested wheat/cereal allergy. PMID:26800201

    Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the "gold standard" for diagnosis of food allergy, shows that questionnaire-based studies overestimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmunologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clinical history, skin prick tests, and laboratory tests to detect serum-food specific IgE, elimination diets and challenges. The primary therapy for food allergy is to avoid the responsible food. Antihistamines might partially relieve oral allergy syndrome and IgE-mediated skin symptoms,but they do not block systemic reactions. Systemic corticosteroids are generally effective in treating chronic IgE-mediated disorders. Epinephrine is the mainstay of treatment for anaphylaxis. Experimental therapies for IgE-mecliated food allergy have been evaluated, such as humanized IgG anti-IgE antibodies and allergen specific immunotherapy.

The most common foods implicated include cow milk, wheat, egg, soy, peanut, tree nuts such as walnuts, hazelnuts, almonds, cashews, pecans, and pistachios, fish and shellfish. The majority of food allergies represent an IgE-mediated hypersensitivity reaction to specific proteins found in foods. Peanut allergy, in particular, is a significant food allergy responsible for the majority of patients with food-induced anaphylaxis. Even trace quantities to food proteins in the sensitized individual can lead to fatal reactions. There is often a rapid onset of symptoms after exposure, with prominent cutaneous findings of urticaria, angioedema, or diffuse nonspecific dermatitis. The majority of children outgrow allergies to milk, soy, egg, and wheat. However, allergy to peanuts, tree nuts, and seafood are usually lifelong conditions, as few outgrow it. Children with food allergies and their families should be knowledgeable of management strategies for the condition, including carrying and properly administering self-injectable epinephrine. New immunotherapeutic options are being investigated and appear promising. PMID:23414152

    Papain is a proteolytic enzyme which is widely used in food industry, pharmaceuticals, and cosmetics. Occupational and non-occupational papain allergies have previously been documented; however, there are limited publications about papain allergy with its relative fruit allergy. Here, we present a case of occupational, IgE-mediated papain allergy with kiwi fruit and fig fruit allergy. A 53-year-old man suffered from rhinitis for several years, with the onset of his symptoms coinciding with the time he started to work at a sausage processing plant where papain is often used as a meat tenderizer. He began to experience symptoms of chest tightness, shortness of breath and wheezing shortly after starting work 5 years ago. Furthermore, he experienced several episodes of oral itching, and tongue and oropharyngeal angioedema after injestion of kiwi fruit and fig fruit. The patient had a lifelong history of allergic conjunctivitis, allergic rhinitis, and childhood asthma. Specific IgE was positive to kiwi fruit, papain and chymopapain (2.95 kUA/L, >100 kUA/L, and 95.0 kUA/L, respectively). Similar bands at 10-15 kDa in blotting with papain and kiwi fruit extracts were found. This patient showed a potential association between papain allergy and sensitization to kiwi fruit. We also reviewed 13 patients with papain allergy published in the literature, with 85% (11/13) of the patients sensitized through the respiratory tract, and 40% (4/11) having atopy. Further studies should focus on the determination of cross-reactive allergens between papain and its fruit relatives, and the prevalence of food allergy in patients with papain allergy should be investigated in a relatively large cohort.

    To investigate soluble IL-2 receptor (sIL-2R) levels in nasal allergy, the sera and nasal secretions from patients with nasal allergy and from healthy subjects were subjected to a double-epitope enzyme-linked immunosorbent assay. Significant elevation of sIL-2R concentrations in the sera and nasal secretions was observed in the allergy patients (n = 26) compared with those of healthy subjects (n = 9). IL-2R-positive (CD25+) cells were observed in the crust formed in an allergic nasal mucosa. ...

    2013-06-01

    Raman spectra of the skin of subjects with nickel allergy are analyzed and compared to the spectra of healthy subjects to detect possible biochemical differences in the structure of the skin that could help diagnose metal allergies in a noninvasive manner. Results show differences between the two groups of Raman spectra. These spectral differences can be classified using principal component analysis. Based on these findings, a novel computational technique to make a fast evaluation and classification of the Raman spectra of the skin is presented and proposed as a noninvasive technique for the detection of nickel allergy.

    Science.gov (United States)

    de Groot, Anton C; Schmidt, Erich

    2016-01-01

    Nearly 80 essential oils (including 2 jasmine absolutes) have caused contact allergy. Fifty-five of these have been tested in consecutive patients suspected of contact dermatitis, and nine (laurel, turpentine, orange, tea tree, citronella, ylang-ylang, sandalwood, clove, and costus root) showed greater than 2% positive patch test reactions. Relevance data are generally missing or inadequate. Most reactions are caused by application of pure oils or high-concentration products. The clinical picture depends on the responsible product. Occupational contact dermatitis may occur in professionals performing massages. The (possible) allergens in essential oils are discussed. Several test allergens are available, but patients should preferably be tested with their own products. Co-reactivity with other essential oils and the fragrance mix is frequent, which may partly be explained by common ingredients. Patch test concentrations for essential oils are suggested.

    1982-05-01

    Alstroemeria plants have increased in popularity in recent years, but surprisingly few cases of contact allergy have been reported. Observations of combined sensitivity between Alstroemeria and Tulipa have given support to the assumption that they contain identical sensitizing agents. A patient working as a gardner developed a dermatitis from Alstroemeria. Patch tests with Alstroemeria were positive, but patch tests with Tulipa were negative. 2 months after test application, the patient showed depigmented areas at the test sites and at the sites of a previous dermatitis. The depigmented test areas remained unchanged at least a year after test application. Whether the depigmentation was due to some unique character of the molecular structure of the unknown Alstroemeria allergen, or to a unique biological characteristic of the patient, remains to be determined.

    Full Text Available Parthenium hysterophorus is a deep rooted three to four feet tall tree at fully flowered stage. The origin of the weed is Caribbean Islands and it can withstand any adverse climate. It is found all over India. It bears white flowers which in turn bears numerous seeds which disper se due to wind or water. July and august is the peak season for these weeds. The parthenium weed produces as much as 3,000 million pollen grains per square meter during the flowering season. They may cause allergic type reactions like asthma, skin rashes, puffy eyes , peeling skin, eczema , running nose, swelling and itching of mouth and nose etc. The ma in cause of parthenium allergy is direct or indirect contact with the parthenium pollen. Here we have reviewed the harmful effects of Parthenium on human beings

    The immune response is a tightly regulated process, which normally results in protection from infection and tolerance of innocuous environmental antigens. However, in allergic disease, the activated immune response results in a chronic pro-inflammatory state characterized by antibody secretion (IgE) and T cell activation to normally well-tolerated antigens. Currently, the treatment of allergic disease is focused on the suppression of key inflammatory mediators or inflammatory cell populations and include anti-histamines, anti-leukotrienes, β2 adrenergic receptor agonists and corticosteroids. However, these approaches only provide a temporary suppression of disease symptoms. Successful long-term treatment can only be provided by allergen-specific immunotherapy (allergen-SIT), which restores normal immunity against allergens. This review will discuss novel approaches to the management of allergy and asthma by targeting the T regulatory cell via modulation of the commensal microbiota and allergen-SIT. PMID:20380589

    2011-01-01

    Allergy is the consequence of an inappropriate inflammatory immune response generated against harmless environmental antigens. In allergic disorders such as asthma and rhinitis, the Th2 mediated phenotype is a result of loss of peripheral tolerance mechanisms. In cases such as these, approaches such as immunotherapy attempt to treat the underlying cause of allergic disease by restoring tolerance. Immunotherapy initiates many complex mechanisms within the immune system that result in initiation of innate immunity, activation of both cellular and humoral B cell immunity, as well as triggering T regulatory subsets which are major players in the establishment of peripheral tolerance. Though studies clearly demonstrate immunotherapy to be efficacious, research to improve this treatment is ongoing. Investigation of allergenicity versus immunogenicity, native versus modified allergens, and the use of adjuvant and modality of dosing are all current strategies for immunotherapy advancement that will be reviewed in this article.

    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.

    2016-06-01

    The interpretation of epidemiological data on food hypersensitivities should clearly separate two issues: the disposition to respond symptomatically to certain foods and the actual reactions occurring, which can be observed only when there is sufficient consumption or targeted exposure/provocation.The exact specification of the case definition is essential for reporting and interpreting food hypersensitivity frequencies. In Europe, prevalence estimates of self-reported reactions are reported from 5.7 to 61.6 %, and physician-diagnosed hypersensitivities from 0.2 to 4.2 %. Consideration of only double-blind proven immediate-type reactions gave estimates ranging from 0.0 to 2.2 %. The disposition for severe reactions against food might be less frequent, but cannot be estimated robustly from published data. The only data available for Germany estimates a prevalence of IgE-mediated reactions of 2,5% for Berlin.The most common triggers of early childhood food allergy are cow's milk and hen's egg, which usually cause mild symptoms, limited to the skin. Food allergy aquired in infancy usually disappears by early school age.The European Anaphylaxis Registry documents the spectrum of severe allergic reactions. England has a larger case series for fatal reactions. No incidence can be estimated from either approach, because reporting is voluntary. Additionally, the discussed data does not inform about the clinical relevance of severe allergic reactions against foods.Future systematic studies about the incidence and course of food hypersensitivity should examine sufficiently large groups of people using objective diagnostic criteria.

    2016-06-01

    Allergen immunotherapy (AIT) was introduced more than a century ago and is yet the only disease-modifying treatment for allergy. AIT is currently conducted with whole allergen extracts and several studies clearly support its efficacy in the treatment of respiratory allergies, however the need for a long treatment - that affects costs and patients compliance - and possible IgE-mediated adverse events are still unresolved issues. Peptide immunotherapy is based on the use of short synthetic peptides which represent major T-cell epitopes of the allergen with markedly reduced ability to cross-link IgE and activate mast cells and basophils. Data from clinical trials confirmed the efficacy and tolerability of peptide immunotherapy in patients with cat allergy, with a sustained clinical effect after a short course treatment. Peptide therapy is a promising safe and effective new specific treatment for allergy to be developed for the most important allergens causing rhinitis or asthma. PMID:26901667

    Allergy to latex has been increasing as the use of latex products has grown. The increase is disproportionately occurring in those people with myelodysplasias, those who have undergone multiple surgical procedures, and health care providers. Within those groups, the most susceptible to latex allergy are people with other allergies. Early identification of high-risk individuals and their avoidance of products containing latex can minimize the occurrence of this allergic response. Heightened awareness among health care providers is needed because latex is very common in hospitals and clinics. Inadvertent exposure places latex-sensitive individuals in danger of anaphylaxis. Nurses caring for infants and children are able to modify the environment of those at risk for latex allergy, reducing exposure to this potentially dangerous substance. Teaching families of children at risk will help them avoid latex in the home; many common household substances contain latex and are likely to trigger allergic responses. PMID:7565525

    Food allergy is a serious health issue affecting roughly 4% of children, with a substantial effect on quality of life. Prognosis is good for the most frequent allergens with almost all children outgrowing their allergy. However, the long-term implications for disease burden are substantial for children with persistent allergies (eg, peanuts, tree nuts, fish, and shellfish) and for those with high concentrations of milk, egg, and wheat IgE. Antigen avoidance has been the time-honoured approach both for prevention and treatment. However, findings from studies done in the past 5 years show that early contact with food can induce tolerance and desensitisation to foods. We review the epidemiology, natural history, and management of food allergy, and discuss the areas of controversy and future directions in research and clinical practice. PMID:23845860

    A cross-sectional study has been carried out at The National Institutes of Health to examine the prevalence of laboratory animal allergy (LAA) in a population exposed to animals, and to compare the prevalence of general allergy in the exposed v a control group. A group of 289 workers with light-to-moderate exposure to animals, 260 with heavy exposure, and 242 control subjects were interviewed. A slightly greater prevalence of general allergy was found among those working with laboratory animals (39%), than in the control group (33.9%), but the difference was not statistically significant. The prevalence of LAA in the total exposed group was 23.9%. A history of atopic problems and history of allergy to domestic animals correlated significantly with LAA, as did the number of species of animals handled and the average number of hours per week exposed to laboratory animals, with evidence of dose-response relationships.

    In recent years, it is recognized that acquired immunity is controlled by regulatory T cell (Treg). Since fundamental pathophysiological changes of allergy are mainly caused by hyperresponsiveness of immune system to allergens that acquires after birth, Tregs likely play key roles in the pathogenesis of allergy, particularly during the sensitization phase. However, accumulated information indicate that there are several distinctive subtypes of Tregs in man, and each of them seems to play diff...

    The present document offers an update on the recommendations for managing patients with cow's milk allergy - a disorder that manifests in the first year of life, with an estimated prevalence of 1.6-3% in this paediatric age group. The main causal allergens are the caseins and proteins in lactoserum (beta-lactoglobulin, alpha-lactoalbumin), and the clinical manifestations are highly variable in terms of their presentation and severity. Most allergic reactions affect the skin, followed by the gastrointestinal and respiratory systems, and severe anaphylaxis may occur. The diagnosis of cow's milk allergy is based on the existence of a suggestive clinical history, a positive allergy study and the subsequent application of controlled exposure testing, which constitutes the gold standard for confirming the diagnosis. The most efficient treatment for cow's milk allergy is an elimination diet and the use of adequate substitution formulas. The elimination diet must include milk from other mammals (e.g., sheep, goat, etc.) due to the risk of cross-reactivity with the proteins of cow's milk. Most infants with IgE-mediated cow's milk allergy become tolerant in the first few years of life. In those cases where cow's milk allergy persists, novel treatment options may include oral immunotherapy, although most authors do not currently recommend this technique in routine clinical practice. Enough evidence is not there to confirm the efficacy of elimination diets in the mother and infant for preventing the appearance of cow's milk allergy. Likewise, no benefits have been observed with prebiotic and probiotic dietetic supplements in infants for preventing food allergy. PMID:25800671

    Full Text Available Abstract Background Food allergy prevalence is increasing in US children. Presently, the primary means of preventing potentially fatal reactions are avoidance of allergens, prompt recognition of food allergy reactions, and knowledge about food allergy reaction treatments. Focus groups were held as a preliminary step in the development of validated survey instruments to assess food allergy knowledge, attitudes, and beliefs of parents, physicians, and the general public. Methods Eight focus groups were conducted between January and July of 2006 in the Chicago area with parents of children with food allergy (3 groups, physicians (3 groups, and the general public (2 groups. A constant comparative method was used to identify the emerging themes which were then grouped into key domains of food allergy knowledge, attitudes, and beliefs. Results Parents of children with food allergy had solid fundamental knowledge but had concerns about primary care physicians' knowledge of food allergy, diagnostic approaches, and treatment practices. The considerable impact of children's food allergies on familial quality of life was articulated. Physicians had good basic knowledge of food allergy but differed in their approach to diagnosis and advice about starting solids and breastfeeding. The general public had wide variation in knowledge about food allergy with many misconceptions of key concepts related to prevalence, definition, and triggers of food allergy. Conclusion Appreciable food allergy knowledge gaps exist, especially among physicians and the general public. The quality of life for children with food allergy and their families is significantly affected.

    Because of its corrosion resistance palladium (Pd) has been widely used in many consumer products ranging from fashion accessories to dental materials. Recently, however, an increase in Pd allergy cases has been reported. Metal allergy is categorized as a Type IV allergy, which is characterized as a delayed-type hypersensitivity reaction in which T cells are known to play an important role; however, the precise mechanism of their action remains unclear. Here we defined the relationship between histamine and the Pd allergic reaction specifically with respect to T cell responses. To verify the effects of histamine on T cells, we examined whether there is a change in IFN-γ production following stimulation of histamine or the antihistamine, olopatadine hydrochloride (OLP), in vitro. In addition, we assessed whether OLP administration affected the degree of footpad swelling or IFN-γ production during the Pd allergy response in mice. We found that histamine stimulation increased IFN-γ production in T cells, specifically enhancing IFN-γ production in CD8(+) T cells compared with CD4(+) T cells. Interestingly, OLP suppressed the production of IFN-γ in CD8(+) T cells, and this compound inhibited footpad swelling and IFN-γ production in mice with Pd allergy. These results suggest that histamine promotes the Type IV allergic reaction and thus, the histamine 1 receptor (H1R) might be useful therapeutic target for treatment of metal allergy. PMID:27035718

    The prevalence of food allergy in childhood increased in the last decades, especially in Westernized countries where this phenomenon has been indicated as a second wave of the allergic epidemic. In parallel, scientific interest also increased with the effort to explain the reasons of this sudden rise and to identify potential protective and risk factors. A great attention has been focused on early exposures to allergenic foods, as well as on other nutritional factors or supplements that may influence the immune system in a positive direction. Both interventions on maternal diet before birth or during breastfeeding and then directly on infant nutrition have been investigated. Furthermore, the natural history of food allergy also seems to be changing over time; IgE-mediated cow's milk allergy and egg allergy seem to be more frequently a persistent rather than a transient disease in childhood, as described in the last years. Food avoidance and the emergency drugs in case of an adverse event, such as epinephrine self-injector, are currently the first-line treatment in patients with food allergies, with a resulting impairment in the quality of life and social behaviour. During the last decade, oral immunotherapy emerged as an optional treatment with remarkable results, offering a novel perspective in the treatment for and management of food allergy. PMID:26595763

    For about a decade, IgE-mediated cannabis (marihuana) allergy seems to be on the rise. Both active and passive exposure to cannabis allergens may lead to a cannabis sensitization and/or allergy. The clinical manifestations of a cannabis allergy can vary from mild to life-threatening reactions, often depending on the route of exposure. In addition, sensitization to cannabis allergens can trigger various secondary cross-allergies, mostly for plant-derived food. This clinical entity, which we have designated as the "cannabis-fruit/vegetable syndrome" might also imply cross-reactivity with tobacco, latex and plant-food derived alcoholic beverages. These secondary cross-allergies are mainly described in Europe and appear to result from cross-reactivity between non-specific lipid transfer proteins or thaumatin-like proteins present in Cannabis sativa and their homologues that are ubiquitously distributed throughout plant kingdom. At present, diagnosis of cannabis-related allergies rests upon a thorough history completed with skin testing using native extracts from buds and leaves. However, quantification of specific IgE antibodies and basophil activation tests can also be helpful to establish correct diagnosis. In the absence of a cure, treatment comprises absolute avoidance measures including a stop of any further cannabis (ab)use. PMID:26178655

    Allergic reactions to fungi were described 300 years ago, but the importance of allergy to fungi has been underestimated for a long time. Allergens from fungi mainly cause respiratory and skin symptoms in sensitized patients. In this review, we will focus on fungi and fungal allergens involved in respiratory forms of allergy, such as allergic rhinitis and asthma. Fungi can act as indoor and outdoor respiratory allergen sources, and depending on climate conditions, the rates of sensitization in individuals attending allergy clinics range from 5% to 20%. Due to the poor quality of natural fungal allergen extracts, diagnosis of fungal allergy is hampered, and allergen-specific immunotherapy is rarely given. Several factors are responsible for the poor quality of natural fungal extracts, among which the influence of culture conditions on allergen contents. However, molecular cloning techniques have allowed us to isolate DNAs coding for fungal allergens and to produce a continuously growing panel of recombinant allergens for the diagnosis of fungal allergy. Moreover, technologies are now available for the preparation of recombinant and synthetic fungal allergen derivatives which can be used to develop safe vaccines for the treatment of fungal allergy.

Material and methods Epicutaneous tests were performed using originally prepared ether extracts of these plants, 0.1% and 3% pet., in 263 individuals: 43 with extrinsic atopic dermatitis, 55 with allergic contact dermatitis, 118 with non-allergic chronic inflammatory skin diseases and 47 healthy adults. Results Our results have shown that testing with both extracts (both concentrations represents a safe method, since no irritation or sensibilization occurred. The overall prevalence of allergy to dandelion extract was 1.14%, and for common chickweed extract 2.28%. Discussion Plant allergies (especially Compositae cannot always be detected by standard screening allergens. Additional testing with dandelion extract can detect most cases, which is in agreement with our results. Isolation of essential oil from common chick-weed proved the allergenic potential of this plant. The prevalence of detected allergy to dandelion as well as to common chickweed was higher than 1 %. Conclusion These ubiquitous weeds and high prevalence of detected allergies have included Vojvodina into a risk zone for getting contact sensitivity to dandelion and common chickweed. Dandelion extract should be considered for Compositae screening series and common chickweed extract for specific plant series in Vojvodina. .

    2016-03-01

    Full Text Available Introduction: Based on the hygiene hypothesis, a low prevalence of Helicobacter pylori (H. pylori infection may explain the recent high prevalence of allergic diseases including food allergy. However, there are very few studies that investigate the relationship between H. pylori and food allergy.Summary: We searched for PubMed, Ovid Medline and the Cochrane library for relevant articles published in English from inception to November 2015. The inverse relationship between H. pylori and food allergy remains unproven because of contradictory and limited evidence at the moment. Likewise, only limited studies have examined the relationship between CagA; one of H. pylori virulence factor and food allergy. On the other hand, in vitro evidence seems to point out a role of H. pylori in the causation of food allergy. The inconsistent results from epidemiological data may be due to small sample size, heterogeneous populations and unstandardised methods or food allergens. Conclusions: Available studies do not support the role of H. pylori in food allergy.

    Food allergies are increasing in prevalence. In order for pediatric clinicians to appropriately diagnose and manage food allergies, the characteristic signs and symptoms of these potentially severe reactions must be recognized. Unlike nonimmunologic adverse food reactions (such as lactose intolerance and food poisoning), food allergies by definition are immune-mediated responses that occur reproducibly on food ingestion. The varying clinical presentations of food allergy include IgE-mediated disorders, mixed IgE- and cell-mediated disorders, and cell-mediated food allergies. This review describes the clinical manifestations of each of these categories of food allergy, with special emphasis on recognition of food-induced anaphylaxis. PMID:26456438

    Full Text Available The best recognized intestinal manifestation of food allergy is food allergic (food-sensitive enteropathy. The feature of enteropathy may include lymphocyte and plasma cell infiltration, epithelial abnormality, or crypt hyperplastic villous atrophy, and impairing absorption, enterophaty continues while the food remains in the diet, remitting on an exclusion diet, and usually recurring on food challenge. Diagnosis is now usually based on histological features at initial biopsy and clinical response to antigen exclusion and challenge. Clinical findings in food allergic enteropathy include abdominal distension, loose stools, micronutrient deficiency, and rarely protein-losing enteropathy. There may be other features of allergic disease, most commonly eczema unlike coeliac disease, food allergic enteropathies are usually transient in early life, and later challenge is usually tolerated. Cow’s milk-sensitive enteropathy (CMSE was the first recognized food allergic enteropathy and remains the most common cause. The best-characterized syndrome is CMSE, classically presenting with chronic loose stools and failure to thrive, often beginning after an episode of gastroenteritis in a formula-fed infant. Other clinical features include abdominal distension, perianal erythema or napkin rash (due to malabsorbed dietary carbohydrates, and deratographia. Associated clinical features may include colic, gastroesophageal reflux, rectal bleeding, or eczema. There may be evidence of micronutrient deficiency, notably for iron and zinc. Up to 40% of infants with classic CMSE also sensitize to soy, often after an initial period when it is tolerated. The great majority however settle on extensively hydrolyzed formulate. Classic CMSE is usually self-limiting, with most children tolerating reintroduction at the age of 2 to 3 years. By contrast, some children may have persistent low-grade symptoms for a prolonged period. A proportion of children manifest additional

    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.

    In this study, we estimated the prevalence of food allergy in the adult allergic patients of Rawalpindi and Islamabad , Pakistan, based on self-report, skin prick test (SPT) and oral food challenge test (OFC). SPT was used for the estimation of sensitization to wheat, egg, milk, beef, chicken, mutton, fish, corn, lentils, rice, soya, peanut and banana. Among 689 patients, 39.19 % showed sensitivity to one or more foods, where, sensitization to wheat (156; 22.6 %) was highest, followed by egg (148; 21.48 %) and milk (138; 20.03 %). Sensitization to various proteins ranged between 15.53-15.97 %, while lentils, corn, rice, soya and peanut sensitization was 15.4, 16, 12.5, 12 and 11.5 % respectively. Only 7.1 % patients were SPT positive for banana allergen. SPT was performed in patients with self-reported food allergy (341/689) and also with no self-reported history of food allergy (348/689). SPT results were positive in 69.8 % of the self-report group, whereas, in the patients with no self-reported food allergy 9.2 % were found sensitized to one or more tested food allergens. 101 patients were recruited for OFC, 61 % of these were confirmed of food allergy. The prevalence of food allergy in the study population was 9 %. Food specific OFC results show that wheat allergy is affecting 1.6 % (95 % CI 0.9-2.84 %) of the total allergy patients, followed by egg allergy 1.31 % (95 % CI 0.70-2.47 %). Furthermore, corn allergy, rice allergy and peanut allergy were 1.02, 0.87 and 0.73 %, respectively. In conclusion, wheat allergy is the most prevalent, followed by egg, chicken, beef and fish allergy, respectively. PMID:27563525

    Thunderstorms have been linked to asthma epidemics, especially during the pollen seasons, and there are descriptions of asthma outbreaks associated with thunderstorms, which occurred in several cities, prevalently in Europe (Birmingham and London in the UK and Napoli in Italy) and Australia (Melbourne and Wagga Wagga). Pollen grains can be carried by thunderstorm at ground level, where pollen rupture would be increased with release of allergenic biological aerosols of paucimicronic size, derived from the cytoplasm and which can penetrate deep into lower airways. In other words, there is evidence that under wet conditions or during thunderstorms, pollen grains may, after rupture by osmotic shock, release into the atmosphere part of their content, including respirable, allergen-carrying cytoplasmic starch granules (0.5-2.5 microm) or other paucimicronic components that can reach lower airways inducing asthma reactions in pollinosis patients. The thunderstorm-asthma outbreaks are characterized, at the beginning of thunderstorms by a rapid increase of visits for asthma in general practitioner or hospital emergency departments. Subjects without asthma symptoms, but affected by seasonal rhinitis can experience an asthma attack. No unusual levels of air pollution were noted at the time of the epidemics, but there was a strong association with high atmospheric concentrations of pollen grains such as grasses or other allergenic plant species. However, subjects affected by pollen allergy should be informed about a possible risk of asthma attack at the beginning of a thunderstorm during pollen season. PMID:17156336

    Cow's milk allergy (CMA) is a complex disorder. Numerous milk proteins have been implicated in allergic responses and most of these have been shown to contain multiple allergenic epitopes. There is considerable heterogeneity amongst allergic individuals for the particular proteins and epitopes to which they react, and to further complicate matters, allergic reactions to cow's milk are driven by more than one immunological mechanism. Finally, the incidence and dominant allergic mechanisms change with age, with IgE-mediated reactions common in infancy and non-IgE-mediated reactions dominating in adults. The complexity of CMA has lead to many public misconceptions about this disorder, including confusion with lactose intolerance and frequent self-misdiagnosis. Indeed, the prevalence of self-diagnosed CMA in the community is 10-fold higher than the clinically proven incidence, suggesting a sizable population is unnecessarily eschewing dairy products. Avoidance of dairy foods, whether for true or perceived CMA, carries with it nutritional consequences and the provision of appropriate nutritional advice is important. In this review, the epidemiology and natural course of CMA is discussed along with our current understanding of its triggers and immunological mechanisms. We examine current strategies for the primary and secondary prevention of allergic sensitization and the ongoing search for effective therapies to ultimately cure CMA. PMID:16373958

    Full Text Available It is estimated that as much as 6-8% population suffers from food allergy or food antigen-related disorders. The prevalence keeps rising. So far we do not have identified remedy to treat food allergy. Avoidance of the offending food is the only effective method currently. Skewed T helper 2 polarization is one of the major feature in the pathogenesis of food allergy. However, the causative mechanism in the initiation of food allergy remains to be further understood. Research in food allergy has got giant advance in recent years. Several animal models have been established and used in food allergy study. One of the common features of these food allergy animal models is that most of them require using microbial products as adjuvant to sensitize animals. This review documents the recent advance in the mechanistic study on concurrent use of microbial products and food antigens to study food allergy.

    The pathogenesis of asthma continues to be a major topic of interest to our authors with reviews and original papers on the role of viruses, mechanisms of inflammation, biomarkers, and phenotypes of asthma being major topics. A number of papers described new treatments for asthma focusing on blocking the Th2 response reflecting the fact that two decades of work in this area is finally bearing fruit. The pathogenesis of chronic rhinosinusitis is a growing area of interest, but there has been less on the genetics of airways disease than in previous years possibly reflecting the degree of rigour (and therefore a smaller body of work), with which these sorts of studies are now being undertaken. There continues to be a wide range of papers dealing with mechanisms of allergic disease ranging from clinical-based studies to basic research and the use of in vivo animal models especially mice. As before, mechanisms and new approaches to immunotherapy are common themes. Several were published in the allergens section investigating modification of allergens to increase their effectiveness and reduce the risk of adverse events. Risk factors for allergic disease was a common theme in the epidemiology section and food allergy a common theme in clinical allergy with papers on the development of protocols to induce tolerance and attempts to find biomarkers to distinguish sensitization from allergic disease. This was another exciting year for the editors, and we hope the readers of the journal. PMID:26492197

    Food allergy has increased in developed countries and can have a dramatic effect on quality of life, so as to provoke fatal reactions. We aimed to outline the socioeconomic impact that food allergy exerts in this kind of patients by performing a complete review of the literature and also describing the factors that may influence, to a greater extent, the quality of life of patients with food allergy and analyzing the different questionnaires available. Hitherto, strict avoidance of the culprit food(s) and use of emergency medications are the pillars to manage this condition. Promising approaches such as specific oral or epicutaneous immunotherapy and the use of monoclonal antibodies are progressively being investigated worldwide. However, even that an increasing number of centers fulfill those approaches, they are not fully implemented enough in clinical practice. The mean annual cost of health care has been estimated in international dollars (I$) 2016 for food-allergic adults and I$1089 for controls, a difference of I$927 (95 % confidence interval I$324-I$1530). A similar result was found for adults in each country, and for children, and interestingly, it was not sensitive to baseline demographic differences. Cost was significantly related to severity of illness in cases in nine countries. The constant threat of exposure, need for vigilance and expectation of outcome can have a tremendous impact on quality of life. Several studies have analyzed the impact of food allergy on health-related quality of life (HRQL) in adults and children in different countries. There have been described different factors that could modify HRQL in food allergic patients, the most important of them are perceived disease severity, age of the patient, peanut or soy allergy, country of origin and having allergy to two or more foods. Over the last few years, several different specific Quality of Life questionnaires for food allergic patients have been developed and translated to different

    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.

    In recent years, it is recognized that acquired immunity is controlled by regulatory T cell (Treg). Since fundamental pathophysiological changes of allergy are mainly caused by hyperresponsiveness of immune system to allergens that acquires after birth, Tregs likely play key roles in the pathogenesis of allergy, particularly during the sensitization phase. However, accumulated information indicate that there are several distinctive subtypes of Tregs in man, and each of them seems to play different role in controlling immune system, which complicates the involvement of Tregs in allergy. The aim of the present study is to attempt to classify subtypes of Tregs and summarize their roles in allergy. Tregs should include natural Tregs (nTreg) including inducible costimulator (ICOS)(+) Tregs, inducible/adaptive Tregs (iTreg), interleukin (IL)-10-producing type 1 Tregs (Tr1 cells), CD8(+) Tregs and IL-17-producing Tregs. These cells share some common features including expression of Foxp3 (except for Tr1 cells), and secretion of inhibitory cytokine IL-10 and/or TGF-β. Furthermore, it is noticeable that Tregs likely contribute to allergic disorders such as dermatitis and airway inflammation, and play a crucial role in the treatment of allergy through their actions on suppression of effector T cells and inhibition of activation of mast cells and basophils. Modulation of functions of Tregs may provide a novel strategy to prevent and treat allergic diseases. PMID:24886492

  11. Common environmental allergens causing respiratory allergy in India.

    2002-03-01

    Respiratory allergy affects all age groups but the children are the worst affected by the respiratory allergy. Bioparticles from different biological sources are the main cause of allergy. Pollen grains, fungal spores, insect and other materials of biological origin form the most important allergen load in the air. For the efficient diagnosis of the allergy and its effective treatment it is very important to know about the prevalence, seasonal and annual variations of aeroallergens of the area. India being the climatically diversed country, there is diversity in the flora and fauna of different parts of the country. Atmospheric surveys carried out in different parts of India reveal that, Alanus nitida, Amarantus spinosus, Argemone mexicana Cocos nucifera, Betula utilis, Borasus flabellifer, Caraica papaya, Cedrus deodara, Cassia fistula, Parthenium, Chenopodium album, Dodonaea viscosa, Malotus phillipensis, Plantago ovata, Prosopis juliflora, Ricinus communis, Holoptelea intergifolia are the allergenically important pollens of the country. Among the fungal aeroallergens, Alternaria, Candida aibieans, Aspergillus versicolor, Aspergillus terreus, Aspergillus japonicus, Cladosporium cladosporoides, Fusarium roseum, Ganoderma lucidum,Neurospora sitophila Helminthosporium, Ustilago trtici, Uromyses are important allergens. Dust mites D. farinae, D.pteronyssinus are also important source of inhalant allergens particularly in the coastal areas of the country. Cockroaches, beetles, weevils, mosquitoes, house flies also contribute towards the aeroallergen load and are allergenically implicated. Avoidance of the indoor and outdoor aeroallergens is recommended for better management of respiratory allergy. PMID:12003301

    Food allergy is the primary cause of anaphylaxis in paediatric age affecting roughly 4% of children and their families worldwide, and requiring changes in dietary habits. The prognosis for food allergy in children has traditionally been regarded as good for the most frequent allergens, however the prognosis for cow's milk allergy in the pediatric age is currently considered to be worse than previously believed. There is now enough evidence that measures of avoidance for children at risk did not have any preventive effect whatsoever, but they still came to be counterproductive by avoiding the physiological interaction between food allergens and gastrointestinal mucosal immune system. Programs of specific oral tolerance induction (SOTI) have obtained interesting results in the treatment of food allergy supporting the idea that antigen exposure through gastrointestinal section is important to allow the development of tolerance. Nevertheless this approach is not yet considered "ready" for community recommendations. In this paper we describe our experience in the field of SOTI in children with cow's milk allergy.

    The prevalence of allergy to furry animals has been increasing, and allergy to cats, dogs, or both is considered a major risk factor for the development of asthma and rhinitis. An important step forward in the diagnosis of allergy to furry animals has been made with the introduction of molecular-based allergy diagnostics. A workshop on furry animals was convened to provide an up-to-date assessment of our understanding of (1) the exposure and immune response to the major mammalian allergens, (2) the relationship of these responses (particularly those to specific proteins or components) to symptoms, and (3) the relevance of these specific antibody responses to current or future investigation of patients presenting with allergic diseases. In this review research results discussed at the workshop are presented, including the effect of concomitant exposures from other allergens or microorganisms, the significance of the community prevalence of furry animals, molecular-based allergy diagnostics, and a detailed discussion of cat and dog components.

    Full Text Available Abstract Background Anxious parents have many concerns about the future health of their atopic infants. Paediatricians and primary care practitioners need to seek knowledge on long-term outcomes in order to cope with the increasing caseload of suspected allergy and the concerns of parents. The aim of the study was to assess suspected and diagnosed allergy in infancy as predictors of allergy and asthma in adolescence. Methods Families expecting their first baby and making their first visit to a maternity health care clinic in 1986 were selected as the study population in a random sample. There were 1278 eligible study families. The data were provided of the children at the ages of 9 and 18 months and 3, 5, 12, 15 and 18 years by health care professionals, parents, and adolescents (themselves. Results At the age of 9 months, the prevalence of allergy suspicions was distinctly higher than that of allergy diagnoses. At the age of five years suspected allergy approaches were nil, and the prevalence of diagnosed allergy was about 9%. During the adolescence, the prevalence of self-reported allergy increases steadily up to the age of 18 years, and that of asthma remains at approximately 5%. Suspected allergy at the age of 9 or 18 months and at the 5 years of age does not predict allergy at adolescence. Compared with non-allergic children, children with definite allergy at the age of 5 were over 8 times more likely to have allergy and nearly 7 times more likely to have asthma in adolescence. Conclusion An early ascertained diagnosis of allergy, but not suspicions of allergy, predicts prevailing allergy in adolescence. Efforts need to be focused on accurate diagnosis of early childhood allergies.

    The number of infant formulas intended for food allergy treatment or prevention has been increasing. Some products fulfill the criteria for hypoallergenicity, such as extensively hydrolyzed protein (casein or whey) and synthesized amino acid formulas (elemental diet). Numerous partially hydrolyzed formulas have been derived from bovine milk, soybean, and rice. They are not hypoallergenic and are not recommended for children allergic to the parent protein, yet certain preparations have shown efficacy for allergy prevention. Soybean-derived preparations, although not hypoallergenic, have been tolerated by a majority of children allergic to bovine milk. Studies on the addition of probiotics or prebiotics to infant formulas have shown inconsistent findings. Numerous hypoallergenic formulas or milk substitutes are available for pediatricians to choose for children with food allergy. Caution is needed in prescribing formulas that are erroneously marketed as hypoallergenic. [Pediatr Ann. 2016;45(4):e150-e156.]. PMID:27064473

    The prevalence of the atopic diseases asthma, rhinitis and atopic eczema has increased in the past two to three decades. It is not unusual to read the statement that food additives and other chemicals in food increase the risk of allergy. From a theoretical standpoint chemicals in the diet may...... influence allergic sensitization and elicitation in different ways: (i) they may directly cause allergy because they are allergens or haptens; (ii) they may act as adjuvants facilitating allergy to other (dietary) components; (iii) they may modulate the immune system by direct immunotoxicity and in theory...... be able ta change the balance from tolerance to IgE production; and (iv) they may trigger non-allergic intolerance reactions. With the present knowledge of chemicals in foods, the human exposure to these chemicals, and the described trends in this exposure, there is no supportive evidence confirming...

    Food allergy affects up to 6% of children and 3-4% of adults in Westernized countries, and is the most common cause of outpatient anaphylaxis in most studies. The mainstay of treatment is strict avoidance of the offending allergens and education regarding the use of emergency medication in cases of accidental ingestions or exposures. While these approaches are generally effective, there are no definitive treatments that cure or provide long-term remission from food allergy. However, with recent advances in characterizing food allergens and understanding humoral and cellular immune responses in food allergy, several therapeutic strategies are being investigated. Potential treatments include allergen-specific immunotherapy as well as allergen-nonspecific approaches to downregulate the overall allergic response in food-allergic individuals. PMID:20477008

    Food allergy is an immune provocation induced by certain food in susceptible individuals. Most of the food allergic manifestations are evident in the individual having impaired oral tolerance. In spite of worldwide prevalence, there is no permanent cure of food allergy. Food allergic reactions are complex immunological events that comprises of several immune molecules like IgE, IL-4, IL-13 and T-cells, therefore, researchers are trying to pick the correct molecule to find out pivotal therapeutic solutions. Being a key regulatory molecule in suppressing T-cells functional activities, cytotoxic T-cell lymphocyte antigen-4 (CTLA-4) or cluster of differentiation-152 (CD-152) has contributed a novel and revolutionary dimension toward therapeutic research of several diseases. This review focuses on different immunological and mechanistic perspectives of CTLA-4 in correlation with food allergy. PMID:23254121

    Background and purpose - It is unclear whether delayed-type hypersensitivity reactions against implanted metals play a role in the etiopathogenesis of malfunctioning total knee arthroplasties. We therefore evaluated the association between metal allergy, defined as a positive patch test reaction to...... common metal allergens, and revision surgery in patients who underwent knee arthroplasty. Patients and methods - The nationwide Danish Knee Arthroplasty Register, including all knee-implanted patients and revisions in Denmark after 1997 (n = 46,407), was crosslinked with a contact allergy patch test...... database from the greater Copenhagen area (n = 27,020). Results - 327 patients were registered in both databases. The prevalence of contact allergy to nickel, chromium, and cobalt was comparable in patients with and without revision surgery. However, in patients with 2 or more episodes of revision surgery...

    Sex and gender are the major determinants of health and disease in both men and women. The aim of this review paper was to examine differences in gender and sex in relation to the prevalence and effects of food allergy. There are still major gaps in our knowledge about the kinds of processes which shape men's and women's perceptions and experiences of food allergy. The expression and experience of health and illness may be moderated by variables such as biological vulnerability, exposure to health risks, perception of symptoms, evaluation of risk, information processing and role expectations. This review highlights the complex links between biological sex, gender, and health in general and offers a synthesis of how these may interact to produce sex and gender differences in biopsychosocial manifestations of food allergy. Implications for research and public health practice are discussed. PMID:17002711
