allergy cow's milk

INTRODUCTION: When infants cannot consume breast milk, the most commonly available alternative milk formula is cow milk-based. Due to a rise in the prevalence of cow milk protein allergy (CMPA) among children, this study aimed to assess the biofilm formation and acidogenicity of cow milk-based formulas as well as milk formulas suggested for children with CMPA. METHODS: Cow milk-based formulas with 0%, 10%, or 18% sucrose added, partially hydrolyzed formula (pHF), extensively hydrolyzed formula (eHF), amino acid-based formula (AAF), and soy-based formulas with 0%, or 11% sucrose added were evaluated...

Casein (CN) is the primary allergenic protein in cow's milk, contributing to the worldwide escalating prevalence of food allergies. However, there remains limited knowledge regarding the effect of structural modifications on CN allergenicity. Herein, we prepared three modified CNs (mCN), including sodium dodecyl sulfate and dithiothreitol-induced linear CN (LCN), transglutaminase-cross-linked CN (TCN), and glucose-glycated CN (GCN). The electrophoresis results indicated widespread protein aggregation among mCN, causing variations in their molecular weights...

BACKGROUND: The effect of the amount of transient cow's milk formula (CMF) consumed during the first days of life on IgE-cow's milk allergy (IgE-CMA) is unknown. METHODS: A cohort of 58 patients with IgE-CMA was identified from a large scale population-based study of 13,019 infants followed from birth. A group of 116 infants matched for sex and breastfeeding only duration (beyond the nursery period), and another random group of 259 healthy infants were used as controls...

SCOPE: In cases where breast milk is unavailable or inadequate, hydrolyzed infant formula is recommended as the primary alternative. The aim of this study is to assess and compare the allergenicity of two partially hydrolyzed whey-based formulas (PHF-Ws) using serum samples from patients with cow's milk allergy (CMA). METHODS AND RESULTS: LC-MS/MS technology is used to investigate the peptide distribution in both samples. The immunoreactivity of two PHF-Ws in 27 serum samples from 50 Chinese infants (02 years) with CMA is analyzed...

OBJECTIVE: To identify the out-of-pocket expenses and parent-reported quality of life (QoL) of children with a diagnosis of cow's milk protein allergy (CMPA) between the ages of 0 and 5 using the Food Allergy Quality of Life Questionnaire - Parent Form. METHODS: A cross-sectional study was conducted in two tertiary care centers in Bogotá. Demographic, medical information, and QoL scores were collected by parental interview. We carried out a cost-of-illness analysis based on self-reported out-of-pocket expenses attributed to the treatment as a whole and the family's monthly income...

Despite the widely recommended usage of partially or extensively hydrolyzed milk protein formula (PHF or EHF) for preventing allergic diseases (ADs), clinical studies have been inconclusive regarding their efficacy compared with cow's milk formula (CMF) or breast milk (BM). We aimed to systematically evaluate the effects of PHF or EHF versus CMF or BM on the risk of ADs (cow's milk allergy, allergic rhinitis, eczema, asthma, wheeze, food allergy, and sensitization) in children. We searched PubMed, Embase, Cochrane Library, and Web of Science for clinical trials published from inception to October 21st, 2022...

BACKGROUND: In 2022, the United States experienced a national shortage of infant formula due to a global supply chain crisis and a large-scale domestic formula recall. The existing literature on healthcare providers' (HCPs) clinical decision-making during formula shortages is limited. This study aims to analyze the factors influencing pediatric HCP clinical decision-making when switching between amino acid formulas (AAF) for managing cow's milk protein allergy (CMPA) in infants under 24 months of age during an unprecedented national formula shortage...

INTRODUCTION: this study aimed to investigate the prevalence and management of food allergies (FA) and drug allergies (DA) in Morocco. Sparse and conflicting epidemiological data exist on the exact prevalence of allergies in the country. The rise in allergies can be attributed to various factors. METHODS: the study analyzed data from patients with suspected FA and DA who sought medical attention. Statistical tests were used to analyze the data, percentages were computed for qualitative variables, and for quantitative variables, medians or means accompanied by standard deviations (SD) were calculated...

OBJECTIVES: To explore the changes in gut microbiota and levels of short-chain fatty acids (SCFA) in infants with cow's milk protein allergy (CMPA), and to clarify their role in CMPA. METHODS: A total of 25 infants diagnosed with CMPA at Children's Hospital Affiliated to Zhengzhou University from August 2019 to August 2020 were enrolled as the CMPA group, and 25 healthy infants were selected as the control group. Fecal samples (200 mg) were collected from both groups and subjected to 16S rDNA high-throughput sequencing technology and liquid chromatography-mass spectrometry to analyze the changes in gut microbial composition and metabolites...

OBJECTIVES: To explore the risk factors associated with cow's milk protein allergy (CMPA) in infants. METHODS: This study was a multicenter prospective nested case-control study conducted in seven medical centers in Beijing, China. Infants aged 0-12 months were included, with 200 cases of CMPA infants and 799 control infants without CMPA. Univariate and multivariate logistic regression analyses were used to investigate the risk factors for the occurrence of CMPA...

Pediatricians and allergists have noted a recent increase in cases of food allergy and anaphylaxis to peanuts and nuts, affecting very young children with worrying consequences in terms of quality of life. Children suffering from persistent cow's milk protein allergies that do not heal spontaneously are at very high risk of a fatal accident. Based on the findings of these studies, recommendations for primary prevention are made.

PURPOSE OF REVIEW: Over the past two decades, food allergy prevention strategies have shifted from 'delayed introduction' to 'no delayed introduction' to 'early introduction' of allergenic foods. This article reviews important research in this field published in the early 2020s to support future strategies for food allergy prevention. RECENT FINDINGS: Recent randomized controlled trials (RCTs), systematic reviews, meta-analyses, and real-world studies have reported that early allergenic food introduction, especially peanut and egg, are effective for preventing food allergies...

PURPOSE: Despite the risk of anaphylaxis, oral food challenges (OFCs) are performed clinically for various indications, particularly to confirm tolerance development. This study aimed to assess OFCs by relevant indications and build an outcome prediction model to help determine when to perform OFCs in children who are likely to have developed immune tolerance. METHODS: In total, 432 pediatric OFCs were retrospectively analyzed according to indications. Clinical characteristics, serum total immunoglobulin (Ig) E, blood eosinophils, and specific IgE and IgG4 levels for food allergens were noted and compared...

The prevalence of food allergy has increased in some regions of the world, and with it the incidence, according to geographical variability, in the phenotype and clinical manifestations. Food allergy arises from the specific immune response induced by exposure to the proteins of a certain food. Food intolerance refers to non-immune reactions, caused by unique physiological characteristics of the individual, including metabolic, toxic, pharmacological and undefined mechanisms. Adverse reactions to foods are classified as: IgE-mediated: Type I Hypersensitivity, non-IgE-mediated: Type IV Hypersensitivity, mixed: Types I and IV Hypersensitivity Non-Allergic; toxic, pharmacological, metabolic, intolerances...

Food allergy is very common throughout the world and has become a major public health problem, with 220 million people suffering from it. Food allergy has been disproportionately observed in people from industrialized or Western countries and was previously considered to predominate in the pediatric versus adult population. However, the current exponential growth of the adult population and older adults, especially in Western countries, and environmental and lifestyle changes, have profoundly changed the epidemiology of food allergy, with a growing increase even at advanced ages...

The objective of the present study is to assess the rates of acquired tolerance to cow's milk (CM) after 36 months in subjects who consumed amino acid-based formula with synbiotics (AAF-S) or amino acid-based formula without synbiotics (AAF) during a 1-year intervention period in early life as part of the PRESTO study (Netherlands Trial Register number NTR3725). Differences in CM tolerance development between groups were analysed using a logistic regression model. Results show that the proportion of subjects (mean [±SD] age, 3...

CONTEXT: Probiotics show promise in preventing and managing food allergies, but the impact of supplementation during pregnancy or infancy on children's allergies and gut microbiota remains unclear. OBJECTIVE: This study aimed to assess the effects of maternal or infant probiotic supplementation on food allergy risk and explore the role of gut microbiota. DATA SOURCES: A systematic search of databases (PubMed, Cochrane Library, Embase, and Medline) identified 37 relevant studies until May 20, 2023...

Cow's milk allergy (CMA) is one of the most common and complex presentations of allergy in early childhood. CMA can present as IgE and non-IgE mediated forms of food allergy. Non-IgE mediated CMA includes food protein-induced enterocolitis syndrome (FPIES), eosinophilic gastrointestinal disorders (EGIDs), and food protein-induced proctocolitis (FPIAP). There are recent guidelines addressing CMA diagnosis, management, and treatment. Each of these guidelines have their own strengths and limitations. To best manage CMA, individualized avoidance advice should be given...

Background: Since human milk contents does not meet the high need of very low birth weight infants, fortification of breast milk is a standard practice for this population. As donkey milk has been long considered for children allergic to cow's milk proteins due to its low allergic properties, a new donkey milk-derived fortifier (DF) has been recently evaluated as a valid alternative to bovine milk-derived fortifier (BF). It seems to improve feeding tolerance when compared with standard BF, with similar neurodevelopmental and auxological outcome at 18 months of age...
