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...

The competitive enzyme-linked immunosorbent assay technique was used to evaluate aflatoxin M1 (AFM1) levels in 168 samples of raw milk (135 samples and 33 samples from bulk tanks of farms and milk collection centers, respectively) and 12 samples of pasteurized milk in Fars province, Southern Iran. AFM1 was found in 55.56% of the samples with a mean concentration of 21.31 ng/L. The concentration of AFM1 in raw milk samples from farms was significantly (p<0.05) lower than that in samples from collection centers and pasteurized milk...

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...

The progression of insulin resistance in dairy cows represents a maternal adaptation to support milk production during heightened energy demand; however, excessive adipose tissue lipolysis can develop. In diabetic non-ruminants, the mechanisms that mediate insulin resistance involve the sphingolipid ceramide. We tested the hypothesis that ceramide accumulates in dairy cows experiencing lipolysis and insulin resistance. Nine dairy cows were utilized in a replicated 3 × 3 Latin square design. Cows were ad libitum fed, nutrient-restricted (NR), or NR with nicotinic acid (NA; 5 mg of NA/h per kg BW; delivered i...

Feeding dried distillers grains with solubles (DDGS), a feed high in fat and protein, to lactating beef cows can alter milk production and composition, resulting in improved pre-weaning growth of progeny. This alteration in milk profile may consequently alter the growth and carcass composition of the offspring after weaning. Therefore, Angus×Simmental steers (n=48) whose dams were fed one of two diets supplemented with either DDGS or soybean meal (CON) from calving to mid-lactation were placed in a feedlot to determine the effects of maternal nutrition during lactation on progeny development and carcass composition...

Oral immunotherapy (OIT) is used regularly for young children with cow's milk (CM) allergy and has been shown to be effective in several studies. However, adverse events occur frequently during OIT. Furthermore, there are only five randomized controlled trial studies of CM-OIT and these are low-powered single center trials. Therefore, evidence levels are also low and sometimes frequent and severe allergic events occur during the OIT. Furthermore, there are no standardized protocols in pediatric allergy guidelines from several countries and studies with long-term follow-up observations and clinical tolerance defined as sustained unresponsiveness are rare...

BACKGROUND: Using whole genome sequence data might improve genomic prediction accuracy, when compared with high-density SNP arrays, and could lead to identification of casual mutations affecting complex traits. For some traits, the most accurate genomic predictions are achieved with non-linear Bayesian methods. However, as the number of variants and the size of the reference population increase, the computational time required to implement these Bayesian methods (typically with Monte Carlo Markov Chain sampling) becomes unfeasibly long...

Maternal heat stress during late gestation affects calf function during postnatal life. The objective of the present study was to evaluate whether calves that experience heat stress in utero have altered thermoregulatory responses to acute heat stress later in life. Specifically, the hypothesis was that heat stress in utero would improve the response to acute heat stress at maturity. Females were born to dams exposed to heat stress or cooled during late gestation preceding their birth. All animals were raised postnatally under identical management...

Since there is no in vitro test, which can accurately predict the clinical relevance of a sensitization to food, the oral food challenge still remains the most reliable procedure to confirm or exclude food allergy and to assess the development of tolerance in children with potentially transient food allergies such as to cow's milk, hen's egg, wheat or soy. Although in the last few years component-resolved diagnostic has improved the food allergy diagnostics, especially in peanut and tree nut allergy, the majority of patients still need to undergo oral food challenge...

Food protein-induced enterocolitis syndrome (FPIES) is a potentially severe presentation of non-IgE-mediated gastrointestinal food allergy (non-IgE-GI-FA) with heterogeneous clinical manifestations. Acute FPIES is typically characterized by profuse vomiting and lethargy, occurring classically 1-4 hours after ingestion of the offending food. When continuously exposed to the incriminated food, a chronic form has been described with persistent vomiting, diarrhea, and/or failure to thrive. Although affecting mainly infants, FPIES has also been described in adults...

BACKGROUND: IgE-mediated cow's milk allergy (CMA) has been shown consistent in milder heated-milk tolerant and severe heated-milk reactant groups in patients older than two years. Little is known whether fermentation of milk gives rise to similar clinical phenotypes. We aimed to determine the influence of extensively heated and fermented cow's milk on the IgE-mediated and non-IgE-mediated CMA in children younger than two years. METHODS: Subjects followed with the diagnosis of IgE-mediated and non-IgE-mediated CMA for at least six months underwent unheated milk challenge...

Excessive ambient temperature and humidity can impair milk production and fertility of dairy cows. Selection for heat-tolerant animals is one possible option to mitigate the effects of heat stress. To enable selection for this trait, we describe the development of a heat tolerance breeding value for Australian dairy cattle. We estimated the direct genomic values of decline in milk, fat, and protein yield per unit increase of temperature-humidity index (THI) using 46,726 single nucleotide polymorphisms and a reference population of 2,236 sires and 11,853 cows for Holsteins and 506 sires and 4,268 cows for Jerseys...

Yvan Vandenplas
Introduction: The prevention and management of cow milk allergy (CMA) is still debated. Since CMA is much less frequent in breastfed infants, breastfeeding should be stimulated. Method: Literature was searched using databases to find original papers and reviews on this topic. Results: Hydrolysates with a clinical proof of efficacy are recommended in the prevention and treatment of CMA. However, not all meta-analyses conclude that hydrolysates do prevent CMA or other atopic manifestations such as atopic dermatitis...

Glucose is essential for numerous cellular functions due to its involvement in energy supply from early development to adulthood. In the lactating cow, glucose demands by the mammary gland significantly increase to support milk production when compared with other tissues. Thus, insufficient blood glucose levels might predispose dairy cows to metabolic disturbances. The intravenous glucose tolerance test (ivGTT) is a suitable tool to characterize glucose metabolism and insulin responses, but results must be reliable and repeatable...

BACKGROUND: Cow milk (CM) allergy (CMA) affects up to 3% of the paediatric population and recent data suggest that only about 50% will outgrow by age 8. Oral immunotherapy (OIT) is a type of immune-modulating treatment that is able to induce desensitization to food allergens, to increase tolerance threshold, to reduce the risk of anaphylaxis, and to improve the patient's quality of life. The examination of the immunological changes observed during the establishment of food allergy (FA) desensitization in FA patients is a window into the pathogenesis of food allergy and food tolerance development...

BACKGROUND: To date, despite the facts that pasteurized milk is the most consumed dairy product in Iran and its consumption has increased almost two fold during the last 10 years, no data are available concerning the concentrations of polychlorinated biphenyls (PCBs) in commercial cow milk in Iran market. METHODS: This study designed to determine the levels of PCBs in these products and to assess population exposure to PCBs by estimating the daily intakes. Pasteurized cows' milk samples (10 brands) were collected from local markets at two different seasons and analyzed using sensitive and reliable methods...

Periparturient dairy cows experience impaired immune function, exhibited as a transient decrease in neutrophil function and neutropenia. This decrease in immune competence is associated with an increase in susceptibility to bacterial infections, including mastitis and metritis. Bovine granulocyte colony stimulating factor (bG-CSF) is an endogenous protein that enhances neutrophil bactericidal functions and increases the production of neutrophils from bone marrow precursors. Administration of pegbovigrastim (recombinant bG-CSF covalently bound to polyethylene glycol) around the time of calving has been shown to reduce the incidence of new clinical mastitis cases in a natural disease model system...

PURPOSE OF REVIEW: We sought to describe the available evidence supporting the utilization of the molecular allergen analysis (MAA) for diagnosis and management of cow milk protein allergy (CMPA). RECENT FINDINGS: Cow milk proteins are among the most common food allergens in IgE- and non-IgE-mediated food allergic disorders in children. Most individuals with CMPA are sensitized to both caseins and whey proteins. Caseins are more resistant to high temperatures compared to whey proteins...
