Active clinical trials for "Milk Hypersensitivity"

Food allergies have become a relevant health problem in westernized societies, particularly, with children. Cow's milk (CM), along with hen's eggs, are the most common foods eliciting allergic reactions in children under 4 years of age. The main objective of this intervention study is to evaluate the safety and efficacy of the intervention known as "The Milk Ladder" in the development of tolerance by children with CM allergies. This will be compared to an historical cohort (CoALE), which investigated the natural history of this allergy. Additionally, the ability of informative epitopes will be evaluated for their potential to predict tolerance and their correlation against clinical variables. The "Milk Ladder" will be evaluated within a prospective cohort of CM allergic children. This intervention is enacted through the introduction of meals cooked with progressively increasing amounts of cow's milk into the participant's diet. The primary outcome will be the development of tolerance which will be evaluated through a double-blind placebo-controlled food challenge. IgE and IgG4 epitopes will be described using a peptide microarray immunoassay. Quality of life will be determined by administering the FAQLQ-PF disease-specific questionnaire. Finally, within a subgroup of study participants, the ability of different peptides to activate basophils will be analyzed, and CM T cell epitopes will be studied by means of T-cell proliferation and cytokine production assays.

Egg, milk and cereal allergies are the most important food allergies in Finnish children, the prevalence in western countries is 1-4 %. In some individuals food-allergy is maintained in to adulthood. Recent studies suggest that specific oral tolerance induction (SOTI) provides a treatment option in children with continuing allergy with high success rates. The study aims at specific oral tolerance induction in adults allergic to cow's milk or hen's egg. Oral immunotherapy involves taking very small amounts of the allergen, and slowly increasing the amount. Consequently, an elimination diet may be wholly or partially cancelled, without the fear of serious allergic reactions. Another aim is to explore changes in antibody-mediated and cell-mediated immune response to individual components of cow's milk and egg allergens during tolerance induction and compare these with the effect of the treatment.

This is a multi-center, randomized, double-blind, placebo-controlled food challenge to be conducted in infants or children with confirmed IgE-mediated cow's milk allergy (CMA), followed by a 7-day open feeding of the experimental formula.

This clinical trial will compare the amount of fatty acids in whole blood of babies fed one of two study formulas for 4 months.

Cow's milk allergy may be involved in the evolution of sleep apnea in infants. The study will assess the effects of specifies diet changes (i.e. non-milk based formula) on the infant. Specifically , infants will be investigated by sleep studies in order to test this hypothesis.

Cow's milk allergy is the most common food allergy in children. The scenery clinical and epidemiological of cow's milk allergy is significantly changed in the last decade. The severity of the clinical manifestations is still rising, and now cow's milk allergy has become the leading cause of hospitalization for food -induced anaphylaxis in our country. In addition, the overall prevalence of cow's milk allergy is increasing for a gradual reduction in the ability to acquire immunological tolerance to cow's milk protein in the first years of life. These mutations dictate the need to identify strategies to stimulate the acquisition of immunological tolerance in children affected by cow's milk allergy . The mechanisms of acquired immunological tolerance are not yet fully defined . The current view suggests the existence of a dynamic mechanism , consisting of various cellular compartments , which is set in a crucial environmental factors arising mainly from the diet and its effects on the intestinal microbiota. These acquisitions have contributed to the definition of a new concept in the field of human nutrition: immunonutrition. The immunonutrition is the ability, through the intake of specific nutrients on the immune system to interfere directly or indirectly through modulation of the composition and function of the intestinal microbiota. The proponent group has recently shown that it is possible to stimulate a more rapid acquisition of immunological tolerance in children affected by CMA through the administration of extensively hydrolysed casein containing the probiotic Lactobacillus rhamnosus GG (LGG) (Berni Canani et al. J Pediatr 2013) . Several lines of evidence suggest that this effect is induced by a combination of direct immunomodulatory action exerted by some small peptides derived from the beta - casein and the action of lactobacillus GG. It 's well known that the Lactobacillus GG is able to adjust the composition and functions of the microbiota in the child with CMA and directly adjust some immunological mechanisms involved in the pathogenesis of this condition. At the same time other groups have demonstrated the possibility that a high percentage of patients with IgE-mediated CMA is able to tolerate foods containing hydrolyzed cow's milk proteins with different processes. It has also been speculated that these strategies can facilitate the acquisition of immune tolerance in patients with cow's milk allergy. One of these foods is Parmigiano -Reggiano cheese, which is characterized by an ' extensive hydrolysis of the proteins in cow's milk , which degrade the caseins present and generate large amounts of peptides and free amino acids and by the presence of appreciable quantities of Lactobacillus GG in the samples to maturing higher . In a recent study it was shown that 58% of patients suffering from IgE-mediated CMA is able to tolerate a daily intake of normal amounts of this food , especially in the absence of a sensibilization to IgE specific to the beta lactoglobulin. These new findings allow us to hypothesize the use of Parmigiano REggiano cheese as a possible strategy immunonutrition can stimulate the acquisition of immune tolerance in patients with CMA .

Cow's milk protein allergy is defined as an immunological reaction to one or more milk proteins. A variety of symptoms can be suggestive for cow's milk protein allergy . Cow's milk protein allergy is suspected clinically in 5-15% of infants, while most estimates of prevalence of cow's milk protein allergy vary from only 2 to 5 %. Confusion regarding cow's milk protein allergy prevalence is often due to differences in study populations, study design and a lack of defined diagnostic criteria. The importance of defined diagnostic criteria needs to be emphasised. It precludes infants from an unnecessary diet and avoids delay in diagnosis, which can lead to malnutrition. There are two clinical types of cow's milk protein allergy: the immediate and the delayed type. The immediate type usually presents within minutes after the ingestion of cow's milk protein with urticaria, angio-oedema, vomiting or an acute flare of atopic dermatitis and is present in slightly more than half of the patients with cow's milk protein allergy. Delayed reactions such as atopic dermatitis or gastrointestinal symptoms like proctocolitis or enteropathy usually present after hours or days. Immunologically, cow's milk protein allergy can be IgE or non-IgE mediated. IgE mediated reactions are often of the immediate type. Non-IgE mediated reactions are often cell mediated or mixed cell and IgE mediated and are more difficult to prove by specific testing. The immunological reaction differentiates cow's milk protein allergy from other milk induced pathology such as lactose intolerance. A variety of symptoms can be suggestive for cow's milk protein allergy although none of them is diagnostic. A good medical history remains the cornerstone for the diagnosis. The treatment of cow's milk protein allergy is the dietary elimination of cow's milk proteins. In non-breastfed infants and children less than 2 years of age, a substitute formula is mandatory as prescribed by several international scientific societies. Extensively hydrolyzed formulas are used as therapeutic formulas. An extensively hydrolysed formula is often a whey or casein based formula in which the protein has been chopped up in smaller pieces that are less allergenic. Because of high cross-reactivity (up to 80%) and nutritional inadequacy, the use of any other animal milk or soy-based formula is precluded.The infant should be maintained on an elimination diet until the child is between 9-12 months of age or at least for 6 months, whichever occurs first. In most cases, symptoms will improve substantially within 2-4 weeks if diagnosis is correct. According to consensus in literature, a therapeutic formula is a formula tolerated by at least 90% (with 95% confidence) of cow's milk protein allergy infants. The aim of the investigators study is to show the efficacy, tolerance and nutritional adequacy of a newly developed thickened extensively hydrolyzed formula in infants with a proven cow's milk protein allergy. In all included patients, cow's milk protein allergy will have been diagnosed based on a double blind placebo controlled food challenge, considered as golden standard in cow's milk protein allergy diagnosis. To evaluate efficacy of the formula, the formula has to be tolerated by at least 90% (with 95% confidence) of cow's milk protein allergy infants following literature consensus. A symptom diary will be filled out for this purpose by the patients' parents or legal guardians and the patient will be followed clinically by his doctor several times during the study period. Nutritional adequacy of the formula will be evaluated clinically by following growth and weight several times during the study period and by comparing it to the standard WHO growth curves, based on breastfed infants.

The Cow's Milk-related Symptom Score (CoMiSS) tool has been developed to define a score to recognize cow's milk related symptoms in infants and young children. Many infants and toddlers with symptoms that can be related to intake of cow's milk and cow's milk protein allergy (CMPA) are often not diagnosed due to the lack of specific markers. The goal of this trial is to validate the CoMiSS tool in infants suspected of CMPA and investigate if the CoMiSS tool could be an alternative to the open challenge test needed to confirm the diagnosis of Cow Milk Protein Allergy.

Milk is the among the most common food allergens in infants and children. The majority of children outgrow their allergies; however, the exact mechanisms by which food tolerance is achieved are unknown. Strict avoidance of the offending food is currently the only known therapy. However, subjects have been known to lose food hypersensitivity while frequently ingesting small amounts of processed forms of the offending product. The purpose of this study is to investigate whether ingestion of small amounts of processed milk protein will be permitted without compromising the chances of either outgrowing milk hypersensitivity or prolonging the time needed to achieve clinical tolerance.

The primary study outcome will be the evaluation of the hypoallergenicity of a new aminoacid based formula in children with confirmed immunoglobulin (Ig)E- mediated CMA. According to the American Academy of Pediatrics (AAP) Subcommittee on Nutrition and Allergic Diseases a hypoallergenic formula must be tested in infants and children with hypersensitivity to cow's milk proteins, with findings verified by elimination-challenge tests under double-blind, placebo-controlled conditions (DBPCFC).
