A Latin American pediatric gastroenterology group’s understanding of cow’s milk protein allergy diagnosis and treatment: Results of a survey by the Food Allergy Working Group of the Sociedad Latinoamericana de Gastroenterología, Hepatología y Nutrición Pediátrica

Cow milk protein allergy (CMPA) becoming a major public health issue that has attracted the attention of health professionals and researchers. This paper aimed to review the important aspects of both IgE and IgG types of cow’s milk protein allergy in terms of prevalence, clinical manifestation, risk factors, other health-related issues and nutritional therapy proposed for such allergies in the adult and pediatric population in Saudi Arabia. A search on “cow’s milk allergy” was done using PubMed, Google Scholar and Scopus Engine for published papers between 1993 and 2020 to find studies yielding knowledge on that context. The prevalence of cow’s milk protein allergy (CMPA) among infants is now in the range of 2–3%. This type of allergy is also detected in adulthood but less frequently. CMPA is defined as an immunological reaction to specific proteins in milk. CMPA is classified based on its type as an immunoglobulin E (IgE)-mediated form and an immunoglobulin G (IgG)-mediated form, each type representing different immunological pathways. The presence of Genetic aspects, family history and short duration of breastfeeding in the infant are among the risk factors contributing to this form of allergy. Its manifestations mainly present as skin presentation, followed by the gastrointestinal and respiratory presentation in most cases in addition to a life-threatening anaphylactic reaction that may occur in 12% of cases. food allergy committees have developed strict diagnosis criteria, including blood testing for food-specific immunoglobulin E (sIgE), a skin prick test and double-blind placebo-controlled food challenges (DBPCFC) as the gold standard. A diet free of cow’s milk protein (CMP) allergen and including the appropriate alternative milk formula is the first line of prevention recommended by many organizations and food allergy experts. As for Saudi Arabia, more research and clinical trials are required to discuss the various aspects of adult and pediatric CMPA and to provide a better understanding along with good control strategies implementation.

Cow's milk allergy (CM A) is the most common food allergy in young children. Babies who develop cow's milk protein (CMP ) allergy may have one or several of the following symptoms: skin rash or gastrointestinal symptoms (abdominal pain or cramps, vomiting or diarrhea). The symptoms can be controlled through a dairy-free diet. So the diagnosis and elimination of CMP is an essential element in management of children with CM A. This article provides a summary of extensive clinical research behind the Nutrilon Aminoacid, demonstrating the clinical efficacy through 25 years of experience.

Different Sources

Immunological estimating of different diet therapy types became currently very important. The aim of this work was to study the changes of immunological biomarkers during usage of formulas based on different sources of protein in children with food allergy and to assess and predict the effectiveness of diet therapy. The study included 66 children with food allergy in age from 1,5 months to 1,5 years. Observed children were divided into three groups depending on the type of formulas used. The dynamics of immunoregulatory substances (IL-5, TGF β 1, IL-10, IL-4, IL-2, IL-13, Eotaxin3), and allergenspecific IgE and IgG antibodies to cow’s milk protein, α-lactoglobulin, β-laktoglobulin, casein, soy and goat’s milk during diet therapy were evaluated. Observation duration was 28-30 days. The differences in the dynamics of the investigated parameters depending on the type of formula were revealed. Thus, the use of formula based on cow’s milk hydrolysates revealed their primarily effect on cytokines IL-2, IL-5 and growth factor TGF β ; the use of formula based on soy protein revealed combined effect on humoral immunity (allergen specific IgE and IgG antibodies) and IL-5; the use of formula based on goat milk characterized decreased levels of allergenspecific IgG antibodies to the cow’s milk protein and its fractions, reduced allergen specific IgE antibody concentrations to cow’s milk protein and α-lactoglobulin, decreased levels of IL-5, and, exclusive for this formula - reduction of IL-4 level. Accordingly, the assessment of immunological biomarkers can be used to personalize diet therapy in children with food allergy.

Cow’S Milk Protein

Cow’s milk protein allergy (CMPA) is the most common food allergy in infancy. Non-IgE mediated (NIM) forms are little studied and the responsible mechanisms of tolerance acquisition remain obscure. Our aim was to study the intestinal microbiota and related parameters in the fecal samples of infants with NIM-CMPA, to establish potential links between type of formula substitutes, microbiota, and desensitization. Seventeen infants between one and two years old, diagnosed with NIM-CMPA, were recruited. They were all on an exclusion diet for six months, consuming different therapeutic protein hydrolysates. After this period, stool samples were obtained and tolerance development was evaluated by oral challenges. A control group of 10 age-matched healthy infants on an unrestricted diet were included in the study. Microbiota composition, short-chain fatty acids, calprotectin, and transforming growth factor (TGF)-β1 levels were determined in fecal samples from both groups. Infants with NIM-CMPA that consumed vegetable protein-based formulas presented microbiota colonization patterns different from those fed with an extensively hydrolyzed formula. Differences in microbiota composition and fecal parameters between NIM-CMPA and healthy infants were observed. Non-allergic infants showed a significantly higher proportion of Bacteroides compared to infants with NIM-CMPA. The type of protein hydrolysate was found to determine gut microbiota colonization and influence food allergy resolution in NIM-CMPA cases.
