Proteins of animal origin represent physiologically active components in the human diet; they exert a direct action or constitute a substrate for enzymatic hydrolysis upon food processing and consumption. Bioactive peptides may descend from the hydrolysis by digestive enzymes, enzymes endogenous to raw food materials, and enzymes from microorganisms added during food processing. Milk proteins have different polymorphisms for each dairy species that influence the amount and the biochemical characteristics (e...

The effects of dynamic high-pressure microfluidization (DHPM) (80, 120, and 160MPa) treatment and glycation with galactose on the IgE-binding capacity and conformation of β-lactoglobulin (β-Lg) were investigated. The binding capacity of immunoglobulin E (IgE) from patients' sera with cow's milk allergy on β-Lg glycated with galactose decreased after DHPM treatment. β-Lg treated after different DHPM methods and pressures yielded a significant discrepancy in IgE-binding capacity. When β-Lg was pretreated by DHPM, the IgE-binding capacity of β-Lg-galactose conjugates decreased with increasing pressure; however, the conjugates showed higher IgE-binding capacity at 120MPa than that at 80 and 160MPa when the β-Lg-galactose mixture was treated by DHPM...

BACKGROUND: We have previously shown that maternal cow's milk (CM) elimination results in down-regulation of CM-specific IgA antibody levels in BM, but not in serum, suggesting that an entero-mammary link may exist for food-specific antibody-secreting cells. OBJECTIVE: We sought to investigate whether food-specific IgA epitope profiles differ intra-individually between mother's serum and BM. We also examined how infants' food epitope-specific IgA develops in early infancy and the relationship of IgA epitope recognition with development of cow's milk allergy (CMA)...

PURPOSE: The diagnosis of cow's milk (CM) allergy is a challenge. The Cow's Milk-related-Symptom-Score (CoMiSS™) was developed to offer primary health care providers a reliable diagnostic tool for CM related symptoms. The predictive prospective value of the CoMiSS™ was evaluated in three clinical trials. METHODS: Pooled analyses of the three studies were conducted based on regressing the results of the month-1 challenge test on the month-1 CoMiSS™, adjusting for baseline CoMiSS™ using a logistic regression model...

BACKGROUND: An increasing number of infants are diagnosed with food protein induced enterocolitis syndrome (FPIES), a non-IgE-mediated food allergy. Until now, T-cell, food-specific mechanisms have been hypothesized. METHODS: 16 children (11M, 5F), affected by FPIES from cow's milk, wheat, fruit, rice and others, experienced 25 acute episodes managed at our Emergency Department (ED) and eight FPIES reactions during oral food challenges (OFC). We compared the laboratory data in resting conditions, in absence of infectious diseases, with data collected during the 25 acute ED episodes (blood samples drawn at 2 to 12 hours) and the eight positive OFCs (three samples at 2, 6 and 12 hours)...

BACKGROUND: Microarray-based component-resolved diagnostics (CRD) has become an accepted tool to detect allergen specific IgE-sensitization towards hundreds of allergens in parallel from one drop of serum. Nevertheless specificity and sensitivity as well as a simultaneous detection of allergen specific IgG4, as a potential parameter for tolerance development, remain to be optimized. OBJECTIVE: We applied the recently introduced silicon chip coated with a functional polymer named copoly(DMA-NAS-MAPS) to the simultaneous detection of food allergen specific IgE and IgG4, and compared it with ImmunoCAP and ImmunoCAP ISAC...

BACKGROUND: Although most of cow's milk (CM) allergic children will outgrow their allergy, the pathomechanism of the natural development of tolerance remains poorly understood. It has been suggested that the balance between milk specific IgE and IgG4 plays a major role. OBJECTIVE: We aimed to investigate differences in IgE and IgG4 antibody binding to cow's milk (CM) epitopes between patients with persistent CM allergy (CMA) and those that naturally became tolerant...

The gastrointestinal form of food allergy is very common in children. The most frequently observed types are allergic proctitis and proctocolitis. In most cases the symptoms subside within the first 2 months of life. The babies seem healthy, and the only abnormality is a small amount of blood in stool. Symptoms can also include small intestine inflammation and colitis. Patients may present with irritability, abdominal pain, flatulence, colic, postprandial vomiting, chronic diarrhoea, and hindered physical development...

Egg allergy is one of the most common food allergies during childhood along with cow's milk allergy. The measles-mumpsrubella (MMR) vaccine is included in the pediatric immunization schedule and contains egg protein. The currently accepted opinion is that the MMR vaccination should be done in a single dose under medical observation in patients with egg allergy. Although it is reported that the MMR vaccine is safe for that patients, there are some patients who developed anaphylaxis. Generally, the development of anaphylaxis after the previous vaccination is reported as a contraindication...

SCOPE: Food allergy is an increasing global health problem and perinatal administration of probiotic bacteria is currently under investigation in order to prevent the development of allergic diseases. Here, we investigated the impact of neonatal mono-colonization of mice with Lactobacillus casei BL23 on an oral sensitization to cow's milk. METHODS AND RESULTS: Mono-colonized (LC) mice were obtained by inoculating L. casei to germ-free (GF) parents. Nine-week-old GF, LC, and conventional (CV) mice were orally sensitized to cow's milk with cholera toxin as adjuvant...

Cow's milk allergy is defined as an immunologically mediated adverse reaction to cow's milk proteins and it is usually, along with hen's egg allergy, the first food allergy identified in childhood.One of the main aspects to consider when evaluating the allergenic potential of food proteins is the effect of gastric digestion. It is known that allergens are usually able to survive the harsh acidic environment of the stomach, tolerate the presence of surfactants, and resist digestion by pepsin. They might also be digested into high molecular weight peptide fragments, which retain the same, or sometimes increased, IgE-binding...

BACKGROUND: Allergy is common and may be associated with foods, including cow's milk formula (CMF). Formulas containing hydrolysed proteins have been used to treat infants with allergy. However, it is unclear whether hydrolysed formulas can be advocated for prevention of allergy in infants. OBJECTIVES: To compare effects on allergy and food allergy when infants are fed a hydrolysed formula versus CMF or human breast milk. If hydrolysed formulas are effective, to determine what type of hydrolysed formula is most effective, including extensively or partially hydrolysed formula (EHF/PHF)...

BACKGROUND: β-lactoglobulin (BLG), a major allergen in cow milk (CM) can be detected in human breast-milk (BM) and is associated with exacerbation of symptoms in breastfed infants with cow milk protein allergy (CMPA). Currently, it is not known how long lactating mothers who consume dairy products need to withhold breastfeeding. OBJECTIVE: To elucidate the kinetics of BLG in BM after maternal ingestion of a single dose of CM. METHODS: Nineteen lactating mothers, four of whom had infants with CMPA, were instructed to avoid CM for 7 days before ingesting a single dose of CM and to continue to withhold CM thereafter throughout the study period...

Cow's milk and egg allergies are two of the most common food allergies. Manufacturers of food products containing milk or eggs or their derivatives as an ingredient are required by European Union regulations to list their presence on the ingredient label. Under European Union legislation, member states are mandated to carry out food safety monitoring programs to verify compliance with food labeling requirements. Through the Regional Integrated Plan for Food Safety, the Piedmont (Italy) regional authority carries out an annual program to determine the presence of undeclared allergens in foods...

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-, cell-mediated food allergy of unknown prevalence and pathophysiology. Onset is typically during the first year of life; seafood-induced FPIES may start in adulthood. Acute FPIES manifests within 1-4 hours after ingestion with repetitive emesis, pallor, and lethargy progressing to dehydration and hypovolemic shock in 15% of cases. Chronic FPIES manifests with intermittent emesis, watery diarrhea, and poor growth progressing to dehydration and hypovolemic shock over a period of days to weeks...
