Growing Importance of Camel Milk in Human Health

Milk is considered as a complete food as it is rich in proteins, fats, minerals, and vitamins that are essential for human nutrition. Camel milk, a dietary staple in hot and arid regions for millennia, has recently gained attention for its nutritional richness and therapeutic properties. With a global camel population of 35 million, countries in East and Central Africa harbor the largest populations, with Ethiopia ranking second in production after Somalia. Beyond its significance in pastoralist communities, camel milk exhibits diverse health benefits, including anti-aging, anti-inflammatory, and immunomodulatory effects. Its unique chemical composition, including high levels of vitamin C, essential minerals, and protective proteins like lactoferrin, lactoperoxidase, immunoglobulins, and lysozyme, makes it a potential alternative to bovine milk. Camel milk lacks β-lactoglobulin, which causes allergic to cow milk proteins. Notably, camel milk's role in managing conditions such as diabetes, allergies, autism, cancer, tuberculosis, hepatitis, and arthritis. Moreover, its hypoallergenic nature and antimicrobial properties make it a promising functional food. Insulin-like proteins, which imitate insulin's role in controlling blood sugar levels and hence improve glucose uptake, contribute to its efficacy. Camel milk has cosmetic effects due to the presence of α-hydroxy acids, which help to plump the skin and smooth fine lines. Despite its importance, camel milk remains underappreciated, necessitating further research and awareness efforts to unlock its full therapeutic potential and promote its consumption. This paper aims to shed light on the diverse health benefits of camel milk.

Risks of dairy derived excipients in medications for lactose intolerant and cow milk protein allergic patients

The use of lactose and cow milk protein (CMP) as potential allergens in pharmaceuticals and their ability to cause allergic reactions remains a significant concern in medicine. Lactose, a common pharmaceutical excipient due to its inert, inexpensive, and stable properties, is found in many prescription-only and over-the-counter medications. However, despite their widespread use, individuals with lactose intolerance (LI) or cow milk protein allergy (CMPA) may experience adverse reactions to these excipients. This study investigated the prevalence of lactose and other dairy-derived ingredients in pharmaceuticals marketed in Portugal. Using the Summary of Product Characteristics (SmPC) from the INFOMED database, various medications, including analgesics, antipyretics, non-steroidal anti-inflammatory drugs (NSAIDs), and antiasthmatics, were analyzed. Results showed a high prevalence of dairy-derived excipients, particularly in antiasthmatic drugs (62.6%) and NSAIDs (39%). Although CMP are not explicitly mentioned in SmPCs, the presence of lactose as an ingredient poses a risk of cross-contamination. The findings emphasize the need for healthcare professionals to be aware of potential allergens in medications and the importance of developing lactose-free alternatives to ensure the safety of patients with LI and CMPA. Further research is required to assess the safety and implications of lactose in medicines for these populations.

A retrospective comparison of IgE-mediated cow's milk protein allergy management strategies in pediatric cohorts.

Complete avoidance of milk is the usual management for IgE-mediated cow's milk protein allergy (CMPA). A baked milk ladder is a method of dietary advancement therapy in IgE-mediated CMPA in Ireland, while in Spain, avoidance of milk awaiting natural tolerance acquisition through an oral food challenge (OFC) is employed. The aim of this study was to evaluate the use of dietary advancement therapy using a milk ladder compared with complete avoidance of milk for managing IgE-mediated CMPA. This is a retrospective chart review of 371 pediatric patients from the population who have been treated for IgE-mediated CMPA between 2011 and 2020, with the milk ladder (Ireland) or complete avoidance followed by an OFC (Spain). The main outcome was the introduction of cow's milk. Milk ladder patients were 3.67 times more likely to succeed in comparison with milk avoidance (p < .001). Anaphylaxis during the treatment period occurred in 34 patients in the milk avoidance groups, while three patients in the milk ladder group experienced anaphylaxis due to accidental exposure to milk (p < .001). Failure to complete treatment was associated with a higher skin prick test in the milk avoidance group and a raised specific IgE in the milk ladder group. This is the first study that compares outcomes of dietary advancement therapy to complete avoidance for CMPA management, demonstrating that cow's milk can be successfully and safely reintroduced using dietary advancement therapy using a milk ladder.

Innovative application of microencapsulated polyphenols in cereal products: Optimization of the formulation of dairy‐ and gluten‐free pastry

AbstractDuring the last decade, consumers pay much attention to the food they eat. They try to choose functional products that have a beneficial effect on health and well‐being, beyond their typical nutritional function. For this reason, the primary aim of the study was to create a gluten‐free and dairy‐free cereal product with increased polyphenol and fiber content. Microencapsulation technology using freeze‐drying method and trehalose as matrix material was used in order to protect the polyphenols from the degradation during processing. The effect of the content of beta‐glucan concentrate, polyphenol microencapsulation and acai oil on the physicochemical properties of pastry products was studied. Response surface methodology was used to optimize the product formulation. The scope of work included analysis of process efficiency, instrumental analysis of color and texture, analysis of total antioxidant capacity, assessment of the content of polyphenols, flavonoids, and beta‐glucan, volume testing, analysis of the profile of fatty acids and volatile compounds, and assessment of sensory acceptability. Based on the obtained data, a response surface model was developed to determine the optimal recipe for the final product. The predicted data were verified using empirical methods. It was found that the optimal formulation of the product involves incorporating 6.48% polyphenol microcapsules, 7.60% beta‐glucan concentrate and 3.71% acai oil. The final product had higher content of polyphenols and beta‐glucan, as well as higher antioxidant activity compare to conventional product. Moreover, it was characterized by physical characteristics similar to the standard product and high sensory acceptability.Practical applicationsConsumers are currently eager to purchase fortified products with beneficial effects on health and well‐being. The developed functional product with increased polyphenol and beta‐glucan content, high antioxidant activity, is anticipated to garner significant consumer acceptance. The product, with its significant health‐promoting and well‐being enhancing properties, along with characteristics similar to conventional products, is poised to effectively meet consumers' needs and expectations. Additionally, it addresses a market void for bakery items tailored specifically for individuals with gluten intolerance, celiac disease, or cow's milk protein allergy. It provides a safe consumption option for these groups, offering a product similar to conventional items found on shelves that they are unable to consume.

Label-free-based proteomics analysis reveals differential proteins of sheep, goat and cow milk

Regarding the limited information on species protein differences between sheep, goat, and cow milk, the differentially expressed proteins in sheep, goat, and cow milk and their functional differences are analyzed using label-free proteomics technology to identify potential biomarkers. 770 proteins and 2914 peptide segments were identified. The statistical analysis showed significant differences in the relative abundances of the 74 proteins among the sheep, goat, and cow milk. CSN3 and LALBA can be used as potential biomarkers for goat milk, XDH can be used as potential biomarkers for cow milk, and CTSB and BPIFB1 can be used as potential biomarkers for sheep milk. The functional analysis using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes showed that these significantly different proteins were enriched by different pathways including thyroid hormone synthesis and glycerol phospholipid metabolism. The data revealed differences in the amounts and physiological functions of the milk proteins of different species, which may provide an important basis for research on the nutritional composition of dairy products and adulteration identification technology.

Role of Milk-Derived Antimicrobial Peptides and Their Future Perspectives in Pharmaceutical/ Dairy Industries

Milk is a good source of bioactive peptides of high nutritive/ pharmaceutical value. In recent decades, the curiosity about bioactive milk peptides has been increasing because of their positive impact on physiological and metabolic functions in human health. A variety of naturally acquired bioactive peptides have been found in fermented dairy products like sour milk and cheese. Initially, these bioactive peptides are found as inactive forms within the precursor protein sequence and can be released in different ways. They can be generated by gastrointestinal digestion of milk, fermentation of milk with proteolytic microorganisms, or hydrolysis via proteolytic enzymes. Once they are released from the precursor protein sequence, they influence body functions and human health. Peptides derived from cow milk exert multifunctional properties, including antimi-crobial, antidiabetic, antihypertensive, anti-inflammatory, immune-modulatory, antioxidant activ-ities, etc. Bioactive antimicrobial peptides are observed in the Cow milk proteins. The Cow milk peptides afford the non-immune-based defense and control for various microbial infections. These activities depend upon their amino acid composition/ sequence. Potential pathogens are con-stantly exposed to mucosal surfaces (lungs and small intestine). The risk of chronic disease was inhibited by antimicrobial peptides, which may afford natural immune protection with the avoid-ance of microbial resistance. In this regimen, the present review summarizes the milk-derived an-timicrobial peptides obtained from casein/ whey protein, along with their future perspectives in the pharmaceutical and dairy industries.

High Concentrations of Immunoglobulin G Against Cow Milk Proteins and Frequency of Cow Milk Consumption Are Associated With the Development of Islet Autoimmunity and Type 1 Diabetes—The Trial to Reduce Insulin-dependent Diabetes Mellitus (IDDM) in the Genetically at Risk (TRIGR) Study

BackgroundThe Trial to Reduce IDDM in the Genetically at Risk (TRIGR) (NCT00179777) found no difference type 1 diabetes risk between hydrolyzed and regular infant formula. However, cow's milk consumption during childhood is consistently linked to type 1 diabetes risk in prospective cohort studies. ObjectiveOur primary aim was to study whether humoral immune responses to cow’s milk and cow’s milk consumption are associated with type 1 diabetes in TRIGR children. MethodsTRIGR comprised 2159 children with genetic susceptibility to type 1 diabetes born between 2002-2007 in 15 countries. Children were randomized into groups receiving extensively hydrolyzed casein or a regular cow’s milk formula and followed until age 10. Type 1 diabetes related autoantibodies and antibodies to cow’s milk proteins were analyzed. Infant formula intake was measured by structured dietary interviews and milk consumption with a food frequency questionnaire. Associations of milk antibodies and milk consumption with the risk to develop type 1 diabetes were analysed by Cox survival model. ResultsCow’s milk antibody levels both in cord blood [HR for islet autoimmunity 1.30 (95% CI 1.05-1.61); type 1 diabetes 1.32 (1.02-1.71)] and longitudinally from birth to 3 years [islet autoimmunity 1.39 (1.07-1.81); type 1 diabetes 1.43 (1.04-1.96)] were associated with increased risk of developing type 1 diabetes. The amount of regular infant formula was associated with a reduced islet autoimmunity risk in the regular infant formula group [0.92 (0.85-0.99)]. Furthermore, frequent liquid milk consumption after infancy was associated with an increased risk of islet autoimmunity or type 1 diabetes. ConclusionsElevated cow's milk antibody levels and high consumption of liquid milk after infancy are related to type 1 diabetes development in children with an increased genetic susceptibility to type 1 diabetes. Enhanced antibody levels to cow’s milk may provide a biomarker of immune system prone to develop islet autoimmunity. Trial registry numberNCT00179777

Development and Evaluation of Vegan Yogurts and Sour Milk Alternatives from White Lupin (Lupinus albus L.)

Cow milk allergy (CMA) triggers a clinically abnormal immunological response to cow milk proteins. To address this issue, extensive studies have explored milk alternatives from various animal and plant sources. This study introduces a method for producing white lupin milk, resulting in fermented dairy-like products (vegan yogurt and sour milk alternatives). Four commercial yogurt cultures, including two mesophilic (CHN-11, CHN-22) and two thermophilic (YC-380, YC-X11) mixed bacterial cultures, were tested, with thermophilic ones yielding superior sensory outcomes for lupin-based yogurt alternatives. Incorporating inulin (2%) enhanced sensory appeal, particularly evident in strawberry and peach-flavoured variants, which achieved sensory scores comparable to cow milk yogurts. Furthermore, white lupin-based yogurts demonstrated superior water-holding capacity (up to 47.11 g/100 g in comparison with 42.35 g/100 g measured for cow milk yogurt), influencing texture and mouthfeel. They also exhibited favourable fatty acid profiles, notably rich in beneficial unsaturated fatty acids such as linoleic and linolenic acid (up to 10.15% and 8.43%, respectively), indicating potential health benefits. Sensory evaluation underscored the impact of starter cultures on product attributes, with certain cultures yielding more favourable results. In conclusion, white lupin emerges as a promising alternative protein source with the potential to produce high-quality dairylike products. While white lupin-based products hold promise as functional foods for individuals with specific dietary needs, further research is necessary to address potential allergenic concerns associated with white lupin proteins.

Comparative detection of goat's milk casein through various enzyme‐linked immunosorbent assay (ELISA) approaches using caprine alpha‐S1 casein peptides and bovine casein polyclonal antibodies

SummaryCasein causes allergic reactions in cow's milk protein allergy (CMPA) individuals. Casein can cross‐react with cows and goats. Hence, a rapid and highly specific technique is required for its detection. The study aims to evaluate and optimise multiple Enzyme‐Linked Immunosorbent Assay (ELISA) approaches for the detection of casein isolated from goat's milk. The study utilised and optimised various ELISA approaches, including direct, indirect and sandwich with various antibodies. Several parameters of ELISA including pre‐treatments of casein, blocking reagent, concentrations of antibodies and background signal were evaluated. The results showed that sandwich ELISA revealed a good signal‐to‐noise ratio at 1 mg mL−1. Indirect ELISA showed a higher signal‐to‐noise ratio without any heat treatment in comparison to the direct ELISA despite utilising an equivalent concentration (i.e., 10 μg mL−1) of goat's milk casein. The findings provide a theoretical foundation for obtaining a high signal‐to‐noise ratio for antigenicity studies of goat's milk casein to minimise its immunological response.

How consistent are the key recommendations, and what is the quality of guidelines and expert consensus regarding paediatric cow's milk protein allergy?

The objective of this study was to assess the quality and consistency of recommendations in clinical practice guidelines (CPGs) and expert consensus on paediatric cow's milk protein allergy (CMPA) to serve as a foundation for future revisions and enhancements of clinical guidelines and consensus documents. We conducted a comprehensive literature search across several databases, including the Chinese Biomedical Literature Database (CBM), PubMed, Embase, Web of Science, UpToDate, ClinicalKey, DynaMed Plus and BMJ Best Practice. We spanned the search period from the inception of each database through October 1, 2023. We integrated subject headings (MeSH/Emtree) and keywords into the search strategy, used the search methodologies of existing literature and developed it in collaboration with a librarian. Two trained researchers independently conducted the literature screening and data extraction. We evaluated methodological quality and recommendations by using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) and AGREE-Recommendations for Excellence (AGREE-REX) tools. Moreover, we compared and summarized key recommendations from high-quality CPGs. Our study included 27 CPGs and expert consensus documents on CMPA. Only four CPGs (14.8%) achieved a high-quality AGREE II rating. The four high-quality CPGs consistently provided recommendations for CMPA. The highest scoring domains for AGREE II were 'scope and purpose' (77 ± 12%) and 'clarity of presentation' (75 ± 22%). The lowest scoring domains were 'stakeholder involvement' (49 ± 21%), 'rigor of development' (34 ± 20%) and 'applicability' (12 ± 20%). Evaluation with AGREE-REX generally demonstrated low scores across its domains. Conclusion: Recommendations within high-quality CPGs for the paediatric CMPA showed fundamental consistency. Nevertheless, the methodology and recommendation content of CPGs and the expert consensus exhibited low quality, thus indicating a substantial scope for enhancement. Guideline developers should rigorously follow the AGREE II and AGREE-REX standards in creating CPGs or expert consensuses to guarantee their clinical efficacy in managing paediatric CMPA. What is Known: • The quality of clinical practice guidelines and expert consensus on paediatric cow's milk protein allergy (CMPA) remains uncertain. • There is a lack of clarity regarding the consistency of crucial recommendations for CMPA management. What is New: • Improving the methodological quality of guidelines and consensus on CMPA requires greater emphasis on stakeholder engagement, rigorous development processes, and practical applicability. • The recommendations from four high-quality guidelines align. However, addressing clinical applicability, integrating values and preferences, and ensuring actionable implementation are critical to improving the quality of all guidelines.

Impact of processing on the sensitising capacity and cross-reactivity of cow's and camel milk proteins in a Brown Norway rat study

Infant formulas based on hydrolysed cow's milk proteins are used when breastfeeding is not feasible in cow's milk allergic infants. Camel milk has been shown to be well-tolerated by the majority of children with cow's milk allergy (CMA) and may be a substitute in management of CMA. Here we aimed to evaluate the impact of processing on immunogenicity, sensitising, antibody-binding and cross-reactive capacity of cow's and camel milk.Cow's and camel milk were processed by means of enzyme hydrolysis or heat treatment. Brown Norway rats were immunised with PBS, non-processed, enzyme hydrolysed or heat-treated cow's or camel milk. In vivo tests were performed for evaluation of clinical signs. Blood and faecal samples were analysed for levels and specificity of antibody responses.Cow's and camel milk showed similar sensitising capacity. Processing decreased the sensitising capacity of cow's milk, yet only enzyme hydrolysis but not heat treatment decreased the sensitising capacity of camel milk. Processing affected the specificity of antibodies raised in the rats, though the effect differed between cow's and camel milk. The study showed a low cross-reactivity between cow's and camel milk, which was decreased with processing, suggesting that processing of camel milk may improve its usefulness in CMA management.

Managing cow's milk protein allergy during the 2022 formula shortage: decision-making among pediatric healthcare providers.

Cow's milk protein allergy (CMPA) affects 2%-7% of infants and is managed with hypoallergenic formulas. The 2022 recalls of infant formulas due to factors including contamination led to specialty formula shortages, highlighting CMPA management challenges. Understanding healthcare providers' (HCPs) decision-making in transitioning to alternative formulas during shortages is crucial. Limited attention has been given to how pediatric physicians make these choices. This study utilized US HCPs' de-identified survey data to assess driving factors when switching extensively hydrolyzed formulas during shortages. 104 eligible HCPs participated, including general pediatrics, pediatric allergy/immunology, and pediatric gastroenterology specialists. Safety, tolerability, and efficacy were identified as top factors for switching formulas. Formula 1 was considered well-tolerated, patient-accepted, and safe by all HCPs. Most expressed strong belief in Formula 1's safety and effectiveness. Findings inform CMPA management during shortages, offering guidance to HCPs for suitable formula selection and enhanced infant care.

Maternal and Infant Dietary Patterns Are Not Related to Food Allergy Risk in Singapore Children: GUSTO Cohort Study

BackgroundWe previously reported that delayed allergenic food introduction in infancy did not increase food allergy risk until age 4 y within our prospective cohort. However, it remains unclear whether other aspects of maternal or infant diet play roles in the development of childhood food allergy. ObjectivesWe examined the relationship between maternal pregnancy and infant dietary patterns and the development of food allergies until age 8 y. MethodsAmong 1152 Singapore Growing Up in Singapore Towards healthy Outcomes study mother–infant dyads, the infant’s diet was ascertained using food frequency questionnaires at 18 mo. Maternal dietary patterns during pregnancy were derived from 24-h diet recalls. Food allergy was determined through interviewer-administered questionnaires at regular time points from infancy to age 8 y and defined as a positive history of allergic reactions, alongside skin prick tests at 18 mo, 3, 5, and 8 y. ResultsFood allergy prevalence was 2.5% (22/883) at 12 mo and generally decreased over time by 8 y (1.9%; 14/736). Higher maternal dietary quality was associated with increased risk of food allergy (P ≤ 0.016); however, odds ratios were modest. Offspring food allergy risk ≤8 y showed no associations with measures of infant diet including timing of solids/food introduction (adjusted odds ratio [aOR]: 0.90; 95% confidence interval [CI]: 0.42, 1.92), infant’s diet quality (aOR: 0.93; 95% CI: 0.88, 0.99) or diet diversity (aOR: 0.84; 95% CI: 0.6, 1.19). Most infants (89%) were first introduced to cow milk protein within the first month of life, while egg and peanut introduction were delayed (58.3% introduced by mean age 8.8 mo and 59.8% by mean age 18.1 mo, respectively). ConclusionsApart from maternal diet quality showing a modest association, infant’s allergenic food introduction, diet quality, and dietary diversity were not associated with food allergy development in this Asian pediatric population. Interventional studies are needed to evaluate the efficacy of these approaches to food allergy prevention across different populations.

Metabolomics in Children Cow's Milk Protein Allergy: Possible Contribution from a System Biology Approach?

One of the most frequent triggers of food anaphylaxis in pediatric age but also among the most common, early, and complex causes of childhood food allergy is cow's milk protein allergy (CMPA). The diagnostic course and management of this allergy is defined in a complex clinical picture due to several factors. First of all, the epidemiological data are not uniform, mainly as a consequence of the diagnostic methodology used in the various studies and the different age ranges covered. In addition, there is the complexity of terminology, since although CMPA traditionally refers to immune-mediated reactions to cow's milk, it is a term encompassing numerous clinical features with different symptoms and the requirement for specific treatments. Moreover, the differential diagnosis with other very frequent diseases, especially in the first year of life, such as gastro-esophageal reflux disease or colic, is still complex. This can result in misdiagnosis and incorrect treatment, with harmful health consequences and significant economic repercussions. In this context, the combination of several omics sciences together, which have already proved useful in clarifying the allergenicity of cow's milk proteins with greater precision, could improve the diagnostic tests currently in use through the identification of new, more specific, and precise biomarkers that make it possible to improve diagnostic accuracy and predict the patient's response to the various available treatments for the recovery of tolerance.

Probiotics, prebiotics and food allergy: a review.

Background. The review was structured in the following sections: 1) Cow's Milk Proteins Allergy (CMA), 2) Food Allergy to Peanuts and 3) Prevention of Food Allergy. In CMA, studies indicate that extensively hydrolyzed casein formula supplemented with Lactobacillus Rhamnosus GG aids in acquiring tolerance to cow's milk proteins, resolving gastrointestinal symptoms and preventing of other allergic manifestations. In peanut oral immunotherapy (OI), supplementation with Lactobacillus Rhamnosus CGMCC 1.3724 appears to promote sustained desensitization. However, the evidence supporting probiotics for preventing food allergies lacks robustness. Current evidence supports the use of oligosaccharides from breast milk in the first months of life for preventing atopic dermatitis, FA and asthma Methods. A PubMed/Medline search was carried out on articles published between 2011 and 2021 with the following query: ("Food Hypersensitivity"[Mesh]) AND (("Probiotics"[Mesh]) OR ("Prebiotics"[Mesh])). Subsequently, the titles and abstracts were analysed and selected according to established criteria. After full reading of these articles, 54 were included and a narrative review was performed. Results. The review was structured in the following sections: 1) Cow's Milk Proteins Allergy (CMA), 2) Food Allergy to Peanuts and 3) Prevention of Food Allergy. In CMA, studies indicate that extensively hydrolyzed casein formula supplemented with Lactobacillus Rhamnosus GG aids in acquiring tolerance to cow's milk proteins, resolving gastrointestinal symptoms and preventing of other allergic manifestations. In peanut oral immunotherapy (OI), supplementation with Lactobacillus Rhamnosus CGMCC 1.3724 appears to promote sustained desensitization. However, the evidence supporting probiotics for preventing food allergies lacks robustness. Current evidence supports the use of oligosaccharides from breast milk in the first months of life for preventing atopic dermatitis, FA and asthma. Conclusions. The potential of probiotics to be used as therapeutic adjuvants in CMA and peanut OI is promising. However, there is inconsistency regarding the type of probiotic, the dose and duration of supplementation. Further studies are needed to clarify the role of probiotics and prebiotics in FA.

Effect of pulsed ultraviolet light on the degree of antigenicity and hydrolysis in cow's milk proteins

AbstractIn order to reduce the quantity of allergens that are causing harm to consumer, it is imperative that the proteins found in cow's milk undergo controlled hydrolysis. Investigated were the effects of different pulsed UV light fluences (0.1–10 J/cm2) on samples of commercial cow's milk proteins (CCMP: casein (CN), α‐lactalbumin (α‐LA), and β‐lactoglobulin (β‐LG)) and reconstituted cow's milk proteins (RCMP). The degree of hydrolysis (DH) and sodium dodecyl sulfate‐polyacrylamide gel electrophoresis (SDS‐PAGE) profiles in RCMP and CCMP, as well as the degree of antigenicity in RCMP, were assessed for this purpose. The DH increased in CCMP and RCMP samples at the highest fluence applied. SDS PAGE profiles showed a decrease in the intensity of the bands of the CCMP samples for fluences of 5 and 10 J/cm2; however, this was not the case for α‐LA. Finally, the degrees of antigenicity measured with Elisa assay in CN and β‐LG were reduced by 24% and 47%, respectively, at a fluence of 10 J/cm2. Therefore, this nonthermal technology could be an alternative to conventional treatments to reduce the allergenic potential of cow's milk proteins; however, future clinical trials to confirm an anti‐allergenic effect on consumer are needed.Practical ApplicationsPulsed UV light is a nonthermal technology of great relevance in the dairy industry. The aim of this article was to generate knowledge of the effect of pulsed UV light on allergenic dairy proteins. Therefore, this article aimed to demonstrate that pulsed UV light can be a novelty compared with conventional methods of inactivation of commercial and reconstituted dairy allergenic proteins.

A real-world cross-sectional study evaluating the role of an oral amino acid-based supplement in nutrient intake by preschoolers on a cow's milk elimination diet.

Food allergy has several negative nutritional consequences and may persist beyond the first year of lives. This study aimed to assess the role of a complete oral amino acid-based supplement in the diet of children on cow's milk protein elimination diet because of food allergy. This study included two groups of children aged 1-5 years paired by age and socioeconomic status: (1) study group, on cow's milk protein elimination diet plus an oral amino acid-based supplement, and (2) control group, on cow's milk protein elimination diet. Sociodemographic, clinical, anthropometric, and dietary data were obtained through online interviews. Two 24-h dietary recalls were collected on nonconsecutive days. Both groups comprised mostly boys. The study group presented lower values of body mass index. The frequency of feeding difficulties was similar between groups. The study group had a higher intake of energy, protein, carbohydrates, calcium, iron, zinc, phosphorus, magnesium, copper, selenium, vitamins D, E, B1, B2, B6, and B12, niacin, and folic acid compared to the control group. A higher proportion of children in the study group had adequate intake according to the recommendations made for energy, carbohydrates, iron, phosphorus, selenium, vitamins A, D, E, B1, B2, and B6, and folic acid. The use of a complete oral amino acid-based supplement has a positive effect on the diet quality of preschoolers on cow's milk elimination diet because of food allergy, promoting higher intake of energy, calcium, vitamin D, and other essential nutrients.

Knowledge and Attitude of Community Pharmacists Toward Cow Milk Protein Allergy Complications and Treatment in Children: A Cross-Sectional Study in Sudan.

Cow's milk protein allergy is the most frequent type of food allergy in newborns and young children. It affects numerous body systems. A community pharmacist possessing adequate knowledge and appropriate practices is crucial for the management of the disease. : This study aimed to assess the knowledge and attitude of community pharmacists toward the complications and treatment of cow milk protein allergy. A descriptive cross-sectional study was conducted among 332 randomly selected community pharmacists in the Capital of Sudan (Khartoum state). Data were collected using a validated and internally consistent (Cronbach Alpha = 0.712) self-administered questionnaire Descriptive statistics and Chi-square analysis were conducted using Statistical Package for the Social Sciences version 25. The response rate was 95.8%, and about 47.8% of the population had 1-5 years of experience as community pharmacists, and 37.4% of them had a post-graduate degree. Only 30.8% of respondents had good knowledge, while 40.6% had poor knowledge, and 28.6% had scored as having fair knowledge of complications of Cow's milk protein allergy. Regarding knowledge toward treatment, 65.1% of respondents had a poor knowledge, 24.5% had fair knowledge, and only 10.4% had good knowledge. Overall, 39.62% of participants had a positive attitude, and 60.38% had a negative attitude toward this disease. Data analysis showed no significant association between the sociodemographic characteristics of respondents and their knowledge and attitude. Community pharmacists in Khartoum State had inadequate knowledge and attitude about the complications and treatment of cow milk protein allergy. As a result, we recommend the implementation of strategies to raise pharmacists' knowledge and attitude.

Evaluation of Streptococcus mutans Biofilm Formation and Acidogenicity of Infant Milk Formulas for Treating Cow Milk Allergy: An in vitro Study

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. Streptococcus mutans was used as a representative microorganism associated with caries. The acidogenicity after 24-h incubation was assessed by the pH of the formed biofilm and lactic acid formation. Biofilm formation was quantified using crystal violet staining. Additionally, the biofilm characteristics were determined using confocal laser scanning microscopy (CLSM). Comparisons were made among formulas without added sucrose to observe protein-based differences. Furthermore, formulas with different sucrose percentages were compared to explore the impact of sucrose content. Results: When comparing the formulas without added sucrose, the biofilm formation in the cow milk-based formula and pHF were significantly greater than the soy-based formula, eHF, and AAF. In the presence of S. mutans, all formulas reduced the biofilm pH below the critical enamel pH. The cow milk-based formula and AAF showed a significantly lower biofilm pH than the pHF, soy-based, and eHF groups, while the lactic acid production was markedly higher in the cow milk-based formula, pHF and AAF, compared with the eHF and soy-based formula. Adding sucrose into the cow milk-based and soy-based formulas substantially increased biofilm mass. The biofilm pH of the cow milk-based formulas, with or without sucrose, was significantly lower than that of the soy-based formulas. The CLSM indicated distinct biofilm characteristics among the different protein-based formulas, with sucrose supplementation promoting S. mutans aggregation in cow milk-based formula biofilm and increased density and intact biofilm in the soy-based formula. Conclusion: All assessed milk formulas had caries-inducing factors, including those without supplemental sucrose. Among them, the eHF demonstrated the least caries-inducing factors, attributed to its minimal biofilm formation and the highest biofilm pH.
