BACKGROUND: Cow's milk protein allergy is the main allergic problem during the first year of life, possibly owing to immune and gastrointestinal systems poor maturation. To prevent allergic reactions, the content and type of proteins in infant formulas resemble those of breast milk. We believe that reactions are due rather to the amount than to the type of protein. OBJECTIVE: To design a new formula with cow's milk that provides the infant with the main nutrients at an affordable cost and with lower risk for the development of allergies...

BACKGROUND: Oral immunotherapy (OIT) is a promising therapeutic approach to treat food allergic patients. However, there are some concerns regarding its safety and long-term efficacy. The use of non-digestible oligosaccharides might improve OIT efficacy since they are known to directly modulate intestinal epithelial and immune cells in addition to acting as prebiotics. AIM: To investigate whether a diet supplemented with plant-derived fructo-oligosaccharides (FOS) supports the efficacy of OIT in a murine cow's milk allergy model and to elucidate the potential mechanisms involved...

BACKGROUND: The food atopy patch (APT) test has been used in previous studies to help the diagnosis of non-IgE mediated food allergies (FA). The aim of this study was to evaluate the efficacy of different cow's milk APT preparations to predict oral tolerance in children with previous non-IgE-mediated cow's milk allergy (CMA) diagnosis. METHODS: Thirty-two patients non-IgE-mediated CMA diagnosed by oral food challenge (OFC) were enrolled to perform APT with three different cow's milk preparations (fresh, 2% in saline solution, 2% in petrolatum) and comparing with a new OFC after at least three months of diet exclusion...

BACKGROUND: The diagnosis of IgE-mediated cow's milk allergy is often based on anamnesis, and on specific IgE (sIgE) levels and/or Skin Prick Tests (SPT), which have both a good sensitivity but a low specificity, often causing positive results in non-allergic subjects. Thus, oral food challenge is still the gold standard test for diagnosis, though being expensive, time-consuming and possibly at risk for severe allergic reactions. AIM: The aim of the present study was to perform a systematic review of the studies that have so far analyzed the positive predictive values for sIgE and SPT in the diagnosis of allergy to fresh and baked cow's milk according to age, and to identify possible cut-offs that may be useful in clinical practice...

BACKGROUND: the sale of raw drinking milk through automatic dispensers is permitted in some European Member States, but consumers are usually advised to boil the milk before consumption. The present study has been conducted to evaluate the effects of two common domestic boiling techniques on the proteins of raw milk, and, in particular, on their potential allergenicity. RESULTS: Native 1-D electrophoresis, N-terminal amino acid sequencing and immunoblotting have been used to characterize the protein pattern, and to evaluate the possible changes in the allergenic properties of the processed milk...

BACKGROUND: Hydrolyzed diets are used in companion animals for the diagnosis and treatment of adverse food reaction. Similarly, hydrolyzed formulas are used in human infants with severe inflammatory bowel disease or milk allergy, and these must meet the standard of hypoallergenicity through rigorous testing. Unfortunately, no standards are currently applied to hydrolyzed veterinary therapeutic diets, and data for the immunogenicity of feline diets is also not available. Therefore, the main aim of this pilot study was to determine if ex-vivo whole blood stimulation assays could be used to characterize the cytokine response to hydrolyzed commercial diets in a small number of individual healthy immunotolerant cats...

General Practitioners suffer from guideline fatigue. They come fast and furious in many complicated forms. Cow's milk allergy (CMA) is one of the most common presentations of food allergy seen in early childhood presenting to primary and secondary care. The early and accurate diagnosis continues to be highlighted in many countries worldwide. International surveys have found that primary care clinicians would like clearer explanations for the options for the diagnosis of CMA and in so doing a means to increase their understanding of management options for both IgE and Non IgE mediated CMA...

Although allergic inflammation is characterized by a T helper (Th) 2-dominant immune response, the discovery of a role for new T cell subsets in inflammatory diseases has added an additional layer of complexity to the understanding of the pathogeneses of allergic diseases. We evaluated plasma cytokine profiles in infants with cows' milk allergy (CMA), who were being treated with an elimination diet. In a prospective, randomized and controlled study, infants (aged 8.4 ± 3.9 months) with CMA were treated with an elimination diet for 120 days, which replaced cows' milk with a hydrolysed soy protein formula (n = 26) or a free amino acid formula (n = 20)...

BACKGROUND AND OBJECTIVES: Reasons for intolerance to commercial amino acid-based formulas (cAAF) in infants diagnosed with cow's milk protein allergy (CMA) remain unknown. We assume that minute amounts of proteins, presenting in the glucose polymers derived from corn starch (cGPs), can elicit the intolerance to the cAAFs observed in some infants with CMA. By replacing cGPs with glucose polymers derived from rice starch (rGPs), a new amino acid-based (nAAF) formula has been shown to be better tolerated than an existing cAAF...

BACKGROUND: Criteria for labelling infant feeds as suitable for the dietary management of cow's milk protein allergy (CMPA) rely on proving the hypoallergenicity of such feeds or clinical studies showing that the feeds are tolerated by 90% of children with proven CMPA. South African (SA) labelling legislation does not indicate what testing is necessary to prove hypoallergenicity. OBJECTIVES: To evaluate all extensively hydrolysed cow's milk formulas and amino acid-based formulas available in SA for residual allergen content, protein size and amino-acid content...
