Maternal diet during pregnancy and lactation may affect the propensity of the child to develop an allergy. The aim was to assess and compare the dietary intake of pregnant and lactating women, validate it with biomarkers, and to relate these data to physician-diagnosed allergy in the offspring at 12 months of age. Maternal diet during pregnancy and lactation was assessed by repeated semi-quantitative food frequency questionnaires in a prospective Swedish birth cohort (n = 508). Fatty acid proportions were measured in maternal breast milk and erythrocytes. Allergy was diagnosed at 12 months of age by a pediatrician specialized in allergy. An increased maternal intake of cow’s milk during lactation, confirmed with biomarkers (fatty acids C15:0 and C17:0) in the maternal blood and breast milk, was associated with a lower prevalence of physician-diagnosed food allergy by 12 months of age. Intake of fruit and berries during lactation was associated with a higher prevalence of atopic eczema at 12 months of age. Our results suggest that maternal diet modulates the infant’s immune system, thereby influencing subsequent allergy development.

We examined whether maternal exposure to food antigens during lactation and maternal allergic status would affect the development of food allergy in offspring. OVA-sensitized or OVA-nonsensitized BALB/c female mice were exposed or unexposed to OVA during lactation. After weaning, their offspring were systemically sensitized twice with OVA and repeatedly given OVA by oral intubation. While 97.1% of the mice breastfed by OVA-nonsensitized and OVA-unexposed mothers developed allergic diarrhea, 59.7% of the mice breastfed by OVA-exposed nonallergic mothers during lactation and 24.6% of the mice breastfed by OVA-exposed allergic mothers during lactation developed food allergy. Furthermore, OVA was detected in breast-milk from OVA-exposed nonallergic mothers during lactation (4.6±0.5 μg/mL). In addition, OVA-specific IgG1 titers were markedly increased in breast milk from allergic mothers (OVA-sensitized and OVA-unexposed mother:11.0±0.5, OVA-sensitized and OVA-exposed mother:12.3±0.3). Our results suggest that oral tolerance induced by breast milk-mediated transfer of dietary antigens along with their specific immunoglobulins to offspring leads to antigen-specific protection from food allergy.

This research aimed to identify the determinants of full breastfeeding (FBF) and any breastfeeding (ABF) cessation before 6 months, through a six-month follow-up of 248 mothers going a postpartum visit. Data were collected by personal interview during the first month and telephone interviews at four and six months postpartum. Cox’s proportional hazards model was used. Not having previous ABF experience, previous ABF duration ≤4 months and worse evaluation of previous experience were associated with cessation of ABF and FBF. Lower educational level was associated with cessation of ABF and the use of pacifiers or occasional breast-milk substitutes with cessation of FBF. Attending childbirth education was a protective factor against early FBF or ABF cessation. Activities supporting breastfeeding should be intensified for mothers with poorer access to information and with negative or without ABF previous experience. The use of pacifiers and not-medically indicated breast milk substitutes should be controlled.

Abstract Background The role of infant feeding for food allergy in children is unclear and studies have not addressed simultaneous exposures to different foods. The goal of this study was to analyze existing data on feeding practices that represent realistic exposure and assess the risk of food allergy symptoms and food allergy in children. Methods The Infant Feeding Practices Study II conducted by the CDC and US-FDA enrolled pregnant women and collected infant feeding information using nine repeated surveys. Participants were re-contacted after 6 years. Food allergy data were collected at 4, 9, 12, and 72 months. In total, 1387 participants had complete infant feeding pattern data for 6 months and information on food allergy symptoms and doctors’ diagnosed food allergy. Feeding patterns constituted six groups: 3-months of feeding at breast followed by mixed feeding, 3-months of breast milk and bottled milk followed by mixed feeding, 1-month of feeding at breast followed by mixed feeding, 6-months of mixed feeding i.e., concurrent feeding of breast milk, bottled milk and formula, 2–3 months of formula followed by formula and solid food, and formula and solid food since the first month. To estimate risks of food allergy, we used linear mixed models, controlling for potential confounders. Results Of the 328 children with food allergy symptoms in infancy and at 6 years, 52 had persistent symptoms from infancy. Children exposed to mixed feeding had a higher risk of food allergy symptoms (Risk Ratio [RR] 1.54; 95% Confidence Interval [CI] 1.04, 2.29) compared to 3-months of feeding at breast adjusted for confounding. No statistically significant risk of infant feeding patterns was found for doctors’ diagnosed food allergy. Paternal allergy posed a higher risk for food allergy symptoms (RR 1.36; 95% CI 1.01, 1.83). Prenatal maternal smoking increased the risk for doctors’ diagnosed food allergy (RR 2.97; 95% CI 1.53, 5.79). Conclusions Analysis of this prospective birth cohort suggest that introduction of multiple feeding source may lead to food allergy symptoms. Future efforts are needed to determine acceptable approaches to improve the ascertainment of food allergy in children and the role of infant feeding.

В течение последних лет частота встречаемости пищевой аллергии у детей постоянно увеличивается. Одной из наиболее частых причин пищевой аллергии у детей грудного возраста является аллергия на коровье молоко. Распространенность пищевой аллергии коррелирует с растущим объемом исследований и публикаций, изучающих связь факторов окружающей среды с формированием оральной толерантности в раннем возрасте. Управление этим процессом происходит в критический период развития, который получил название «окно возможностей», и ключевая роль принадлежит микробиоте и ее метаболитам. В течение этого периода влияние окружающей среды может иметь долгосрочное воздействие на состав микробиоты, иммунную регуляцию и восприимчивость к болезням. События во время этого критического окна влияют на долгосрочное здоровье человека. Ранняя колонизация сообществом микробов в рамках определенного критического временного окна имеет решающее значение для правильного развития иммунной системы. Грудное молоко остается золотым стандартом вскармливания, но роль его в профилактике пищевой аллергии на сегодняшний день не доказана. Более детальное изучение иммунологических факторов грудного молока и механизмов диалога между микробиотой и иммунной системой, в частности, действия определенных компонентов (пробиотики, пребиотики и метаболиты), помогает разработке новых стратегий профилактики иммуноопосредованных заболеваний, в т. ч. пищевой аллергии. Пребиотики, пробиотики и метаболиты представляют на сегодняшний день огромный интерес для управления аллергией через ускорение формирования иммунологической толерантности не только для первичной, но и для вторичной профилактики при лечении аллергии к белкам коровьего молока. In recent years, the incidence of food allergies in children has been steadily increasing. One of the most common causes of food allergy in infants is cow's milk allergy. The prevalence of food allergy correlates with a growing body of research and publications investigating the relationship of environmental factors and immune development inthe newborn. The «window of opportunity» is critical period of early immune development, and the key role belongs to the microbiota and its metabolites. During this period, environmental influences can have long-term effects on microbiota composition, immune regulation, and susceptibility to disease. Events during this critical window affect long-term human health. Early colonization by the microbial community within a certain critical time window is critical for the proper development of the immune system. Breast milk remains the gold standard for feeding, but its role in preventing food allergies has yet to be proven. A more detailed study of the immunological factors of breast milk and the mechanisms of microbiome-immune crosstalk, in particular, the action of certain components (probiotics, prebiotics and metabolites), helps to develop new preventive strategies. Prebiotics, probiotics and metabolites are of great interest today for managing allergies by accelerating the formation of immunological tolerance not only for primary, but also for secondary prevention in the treatment of allergy to cow's milk proteins.
