RESUMEN
To systematically review evidence on the efficacy and safety of using a lactase supplementation for managing infant colic. The MEDLINE, EMBASE, and Cochrane Library databases were searched (up to September 2023) for randomized controlled trials (RCTs) comparing oral lactase supplementation with placebo or no intervention in infants younger than 6 months old with infant colic. The risk of bias was assessed using the revised version of the Cochrane risk-of-bias tool. Outcomes measured were selected according to a standardized core outcome set. Five RCTs involving a total of 391 infants were identified. Three RCTs reported reduced crying duration, but one showed effect only in a compliant group (40.4%, p = 0.0052). A meta-analysis of two RCTs found no difference in crying duration and fussing time during 1 week of lactase treatment compared with placebo (mean difference [MD] -17.66 min/day, 95% confidence interval [CI], -60.8 to 25.5; I2 = 68% and MD 2.75, 95% CI, -58.2 to 57.2; I2 = 80%, respectively). Other outcomes were assessed only in individual studies or not reported. The risk of bias was low in only one RCT, high in three, and raised some concerns in one. While individual trials have shown some promise, the overall evidence for the efficacy of lactase supplementation in treating infant colic remain inconclusive. Further well-designed RCTs are necessary to determine the effects of lactase on managing infant colic.

A previous guideline on cow's milk allergy (CMA) developed by the European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) was published in 2012. This position paper provides an update on the diagnosis, treatment, and prevention of CMA with focus on gastrointestinal manifestations. All systematic reviews and meta-analyses regarding prevalence, pathophysiology, symptoms, and diagnosis of CMA published after the previous ESPGHAN document were considered. Medline was searched from inception until May 2022 for topics that were not covered in the previous document. After reaching consensus on the manuscript, statements were formulated and voted on each of them with a score between 0 and 9. A score of ≥6 was arbitrarily considered as agreement. Available evidence on the role of dietary practice in the prevention, diagnosis, and management of CMA was updated and recommendations formulated. CMA in exclusively breastfed infants exists, but is uncommon and suffers from over-diagnosis. CMA is also over-diagnosed in formula and mixed fed infants. Changes in stool characteristics, feeding aversion, or occasional spots of blood in stool are common and in general should not be considered as diagnostic of CMA, irrespective of preceding consumption of cow's milk. Over-diagnosis of CMA occurs much more frequently than under-diagnosis; both have potentially harmful consequences. Therefore, the necessity of a challenge test after a short diagnostic elimination diet of 2-4 weeks is recommended as the cornerstone of the diagnosis. This position paper contains sections on nutrition, growth, cost, and quality of life.

The recent advisory issued by the United States Food and Drug Administration, cautioning against the routine administration of probiotics in preterm neonates, has sparked a lively debate within the scientific community. This commentary presents a perspective from members of the Special Interest Group on Gut Microbiota and Modifications within the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and other authors who contributed to the ESPGHAN position paper on probiotics for preterm infants, as well as representatives from the European Foundation for the Care of Newborn Infants. We advocate for a more nuanced and supportive approach to the use of certain probiotics in this vulnerable population, balancing the demonstrated benefits and risks.

This position paper by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Special Interest Group on Coeliac Disease (SIG-CD) presents an update to the 2016 recommendations concerning early diet and the risk of coeliac disease (CD). This update adheres to the policy that mandates reviewing guidelines every 5 years, particularly when new data emerge. The 2024 statements and recommendations are essentially similar to the 2016 recommendations. Breastfeeding, whether any amount, exclusive, or of any duration, does not reduce the risk of developing CD. Introducing gluten into an infant's diet at any time between completed 4 months (≥17 weeks) and 12 months of age does not affect the cumulative incidence of CD, although earlier introduction may lead to earlier seroconversion and CD. In observational studies involving cohorts with a known risk for CD, consuming a high amount of gluten compared to a low amount during weaning and in the subsequent childhood years-specifically the first 2-3 years, and even up to 5 years in some studies-was associated with an increased risk for CD. However, the specific optimal amounts of gluten consumption remain undetermined due to insufficient evidence on safe thresholds, and the impact of restricting gluten in the diet of healthy children of unknown risk for CD is unknown. Thus, any recommendation on the gluten amount is currently unjustifiable for the general population and infants with known HLA risk types. There is no specific guidance on the type of gluten-containing foods to be introduced at weaning.

The Cow's Milk-related Symptom Score (CoMiSS) is an awareness tool for evaluating cow's milk-related symptoms. Previous studies have focused on providing CoMiSS values for healthy and symptomatic infants aged 0-6 months. However, there is a notable gap in the literature concerning CoMiSS values for infants older than 6 months. This cross-sectional study aimed to determine CoMiSS values in presumed healthy infants who have completed 6 months and are up to 12 months old, hereafter referred to as 6 to 12 months old. Physicians from six European countries prospectively determined CoMiSS values in infants attending well-child clinics. Exclusion criteria included preterm delivery, acute or chronic disease, and the consumption of a therapeutic formula, dietary supplements (except vitamins), or medication. The following information was collected: gestational age, gender, age, type of feed (breast milk or infant formula), and complementary feeding. Descriptive statistics were summarized with mean and standard deviation for normally distributed continuous variables, median and IQR for non-normally distributed variables, and differences in CoMiSS values were analyzed with appropriate tests. Data from 609 infants were obtained. The overall median (Q1-Q3) CoMiSS values were 3 (1-5). Significant differences were found across age groups (p < 0.001), but not across groups based on gender (p = 0.551) or feeding type (p = 0.880). Conclusions: This study provided CoMiSS values in presumed healthy infants aged 6-12 months. Additional studies should be conducted to establish the use of CoMiSS to assess cow's milk-related symptoms in infants 6 months and older. What is Known: ⢠The Cow's Milk-related Symptom Score (CoMiSS) is an awareness tool for evaluating symptoms related to cow's milk. ⢠CoMiSS values for presumed healthy infants aged 0-6 months infants are already available. What is New: ⢠CoMiSS values in European infants aged 6-12 months are provided. ⢠These CoMiSS values differed across various age groups but not across groups based on gender or feeding type.

BACKGROUND: Formula-fed infants are at increased risk of infections. Due to the cross-talk between the mucosal systems of the gastrointestinal and respiratory tracts, adding synbiotics (prebiotics and probiotics) to infant formula may prevent infections even at distant sites. Infants that were born full term and weaned from breast milk were randomized to prebiotic formula (fructo- and galactooligosaccharides) or the same prebiotic formula with Lactobacillus paracasei ssp. paracasei F19 (synbiotics) from 1 to 6 months of age. The objective was to examine the synbiotic effects on gut microbiota development. RESULTS: Fecal samples collected at ages 1, 4, 6, and 12 months were analyzed using 16S rRNA gene sequencing and a combination of untargeted gas chromatography-mass spectrometry/liquid chromatography-mass spectrometry. These analyses revealed that the synbiotic group had a lower abundance of Klebsiella, a higher abundance of Bifidobacterium breve compared to the prebiotic group, and increases in the anti-microbial metabolite d-3-phenyllactic acid. We also analyzed the fecal metagenome and antibiotic resistome in the 11 infants that had been diagnosed with lower respiratory tract infection (cases) and 11 matched controls using deep metagenomic sequencing. Cases with lower respiratory tract infection had a higher abundance of Klebsiella species and antimicrobial resistance genes related to Klebsiella pneumoniae, compared to controls. The results obtained using 16S rRNA gene amplicon and metagenomic sequencing were confirmed in silico by successful recovery of the metagenome-assembled genomes of the bacteria of interest. CONCLUSIONS: This study demonstrates the additional benefit of feeding specific synbiotics to formula-fed infants over prebiotics only. Synbiotic feeding led to the underrepresentation of Klebsiella, enrichment of bifidobacteria, and increases in microbial degradation metabolites implicated in immune signaling and in the gut-lung and gut-skin axes. Our findings support future clinical evaluation of synbiotic formula in the prevention of infections and associated antibiotic treatment as a primary outcome when breastfeeding is not feasible.

BACKGROUND & AIMS: Screening for celiac disease (CD) is recommended in children with affected first-degree relatives (FDR). However, the frequency of screening and at what age remain unknown. The aims of this study were to detect variables influencing the risk of CD development and develop and validate clinical prediction models to provide individualized screening advice. METHODS: We analyzed prospective data from the 10 years of follow-up of the PreventCD-birth cohort involving 944 genetically predisposed children with CD-FDR. Variables significantly influencing the CD risk were combined to determine a risk score. Landmark analyses were performed at different ages. Prediction models were created using multivariable Cox proportional hazards regression analyses, backward elimination, and Harrell's c-index for discrimination. Validation was done using data from the independent NeoCel cohort. RESULTS: In March 2019, the median follow-up was 8.3 years (22 days-12.0 years); 135/944 children developed CD (mean age, 4.3 years [range, 1.1-11.4]). CD developed significantly more often in girls (P = .005) and in Human Leukocyte Antigen (HLA)-DQ2 homozygous individuals (8-year cumulative incidence rate of 35.4% vs maximum of the other HLA-risk groups 18.2% [P < .001]). The effect of homozygosity DR3-DQ2/DR7-DQ2 on CD development was only present in girls (interaction P = .04). The prediction models showed good fit in the validation cohort (Cox regression 0.81 [0.54]). To calculate a personalized risk of CD development and provide screening advice, we designed the Prediction application https://hputter.shinyapps.io/preventcd/. CONCLUSION: Children with CD-FDR develop CD early in life, and their risk depends on gender, age and HLA-DQ, which are all factors that are important for sound screening advice. These children should be screened early in life, including HLA-DQ2/8-typing, and if genetically predisposed to CD, they should get further personalized screening advice using our Prediction application. TRIAL REGISTRATION NUMBER: ISRCTN74582487 (https://www.isrctn.com/search?q=ISRCTN74582487).

PURPOSE OF REVIEW: The aim is to provide updated information on the concept of postbiotics and recent data on the efficacy of postbiotics for the prevention and treatment of childhood diseases. RECENT FINDINGS: In line with a recently proposed consensus definition, a postbiotic is 'a preparation of inanimate microorganisms and/or their components that confers a health benefit on the host'. Although inanimate, postbiotics may exert health benefits. There are only limited data on infant formulas containing postbiotics, but they are well tolerated, support adequate growth and demonstrate no potential identifiable risks, although clinical benefits remain limited. Currently, there is only limited support for postbiotic use for treating diarrhoea and preventing common paediatric infectious diseases in young children. Given the limited evidence, sometimes with a high risk of bias, caution is justified. No data in older children and adolescents are available. SUMMARY: The consensus definition of postbiotics facilitates further research. As not all postbiotics are the same, the type of disease and specific postbiotic studied should be considered when choosing postbiotics for the prevention or treatment of childhood diseases. Additional studies are needed to assess disease conditions responsive to postbiotics. Mechanisms of action of postbiotics need to be evaluated and characterized.

OBJECTIVE: The dogma of probiotic strain-specificity is widely accepted. However, only the genus- and species-specific effects of probiotics are supported by evidence from clinical trials. The aim of this rapid review was to assess clinical evidence supporting the claim that the efficacy of probiotics in the pediatric population is strain-specific. METHODS: The Cochrane Library, MEDLINE, and EMBASE databases were searched (up to August 2022) for randomized controlled trials (RCTs) conducted in children aged 0-18 years evaluating the effects of prophylactic or therapeutic administration of probiotics (well-characterized at the strain level) for conditions such as antibiotic-associated diarrhea, acute diarrhea, necrotizing enterocolitis, respiratory tract infections, Helicobacter pylori infection, and atopic dermatitis. To allow evaluation of strain-specificity, a trial could only be included in the review if at least one additional RCT assessed the effect of a different strain of the same species against the same comparator. RCTs without proper strain-level data were excluded. In the absence of identifying head-to-head strain versus strain RCTs, indirect comparisons were made between interventions. RESULTS: Twenty-three RCTs were eligible for inclusion. Out of the 11 performed comparisons, with 1 exception (two Lacticaseibacillus paracasei strains in reducing atopic dermatitis symptoms), no significant differences between the clinical effects of different strains of the same probiotic species were found. CONCLUSIONS: Head-to-head comparison is an optimal study design to compare probiotic strains, but such comparisons are lacking. Based on indirect comparisons, this rapid review demonstrates insufficient clinical evidence to support or refute the claim that probiotic effects in children are strain-specific.

BACKGROUND: Synbiotics are a mixture comprising of live microorganisms and substrate(s) selectively utilized by host microorganisms that confers a health benefit on the host. There is an increasing number of studies investigating their role in different diseases and disorders. AIM: The purpose of this article is to provide recommendations for the use of synbiotics in the management of pediatric gastrointestinal disorders. The recommendations are developed by the ESPGHAN Special Interest Group on Gut Microbiota and Modifications. METHODS: From existing literature databases, we searched and appraised all systematic reviews and/or meta-analyses, and subsequently published randomized controlled trials (RCTs) that compared the use of synbiotics, in all delivery vehicles and formulations, at any dose, compared to no synbiotics. Synbiotics which are part of infant formula were not assessed. The recommendations were formulated only if at least 2 RCTs that used a well-defined synbiotic were available. RESULTS: Based on the currently available evidence, no recommendation can be formulated in favor or against the use of evaluated synbiotic combination in the treatment of acute gastroenteritis, prevention of necrotizing enterocolitis, Helicobacter pylori infection, inflammatory bowel disease, functional gastrointestinal disorders, and allergy in infants and children. CONCLUSIONS: There is a need for more, well-designed RCTs on the role of synbiotics in gastrointestinal disorders with the same outcome measures to enable the inter-studies comparisons.

OBJECTIVES: The Cow's Milk-related Symptom Score (CoMISS) is an awareness tool for evaluating cow's milk-related symptoms in otherwise healthy infants <1 year of age. This study assessed whether replacing the Bristol Stool Form Scale (BSFS) with the Brussels Infants and Toddlers Stool Scale (BITSS) in non-toilet-trained infants would modify the overall CoMiSS and change the clinical approach regarding potential cow's milk allergy. METHODS: Non-toilet-trained infants aged <13 months were assessed by CoMiSS using the 7 images from the BSFS (CoMiSS-BSFS) compared to the 4 images of stools from BITSS (CoMiSS-BITSS). The Wilcoxon signed-rank test and Pearson correlation coefficient were calculated. A post hoc analysis using identical tests was performed in subsets of CoMiSS-BSFS scores ≥10, ≥12, ≤5, and ≥6. RESULTS: Eight hundred forty-four pairwise scores were collected. Applying the Wilcoxon test over the complete dataset, the difference between CoMiSS-BSFS and CoMiSS-BITSS was statistically significant ( P < 0.001). However, there was no significant difference in the subsets with CoMiSS-BSFS ≥10, ≥12, and ≥6 ( P = 0.84, P = 0.48, and P = 0.81, respectively). The significant difference remained restricted to the group with CoMiSS-BSFS ≤5, considered at low risk for CM-related symptoms ( P < 0.001). CONCLUSION: Replacing BSFS with BITSS does not change the cutoff for awareness of possible CM-related symptoms and will not impact the use of CoMiSS in clinical practice. Changes in CoMiSS remained limited to the subgroup with a low risk for CM-related symptoms.

RESUMEN
BACKGROUND: Probiotics, defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host, are widely used despite uncertainty regarding their efficacy and discordant recommendations about their use. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Special Interest Group on Gut Microbiota and Modifications provides updated recommendations for the use of probiotics for the management of selected pediatric gastrointestinal disorders. METHODS: All systematic reviews and/or meta-analyses, as well as subsequently published randomized controlled trials (RCTs) (until December 2021), that compared the use of probiotics in all delivery vehicles and formulations, at any dose, with no probiotic (ie, placebo or no treatment), were eligible for inclusion. The recommendations were formulated only if at least 2 RCTs on a similar well-defined probiotic strain were available. The modified Delphi process was used to establish consensus on the recommendations. RESULTS: Recommendations for the use of specific probiotic strains were made for the management of acute gastroenteritis, prevention of antibiotic-associated diarrhea, nosocomial diarrhea and necrotizing enterocolitis, management of Helicobacter pylori infection, and management of functional abdominal pain disorders and infant colic. CONCLUSIONS: Despite evidence to support the use of specific probiotics in some clinical situations, further studies confirming the effect(s) and defining the type, dose, and timing of probiotics are still often required. The use of probiotics with no documented health benefits should be discouraged.

The aim of this study was to assess the compliance between current guidelines on the diagnosis and management of children with cow's milk allergy (CMA) and clinical practice by a survey of Polish physicians. An online cross-sectional survey involving a convenience series of participants was performed from January 15 to March 20, 2020. Data provided by 605 physicians (74.2% of them pediatricians working in general practice) were analyzed. Contrary to the current recommendations, only a minority of respondents (27.4%) reported performing oral food challenge (OFC) to confirm the diagnosis of CMA. Among those who reported performing OFC (n = 160 respondents), the majority performed an open challenge (82.5%). Most respondents (79.2%) correctly recommended as the first-line treatment extensively hydrolyzed cow's milk formula for a child with mild-to-moderate CMA. Less than half of participants (43.8%) recommended amino acid-based formula for a child with severe CMA (anaphylaxis). Only half of respondents (50.8%) reassessed tolerance to cow's milk proteins. For assessing tolerance acquisition, more respondents recommended challenge to baked milk compared with fresh cow's milk (60.5% vs. 39.5%, respectively). This survey study found that only a minority of responding physicians follow current guidelines for diagnosis and management of children with CMA in Poland.

OBJECTIVES: Infant formulas (IF) with postbiotics, defined as inanimate microorganisms and/or their components that confer a health benefit on the host, are available. We systematically updated evidence on the safety and health effects of administering iF with postbiotics (with or without other modifications) compared with standard IF. METHODS: The Cochrane Library, MEDLINE, and EMBASE databases were searched to December 2021. RESULTS: Eleven randomized controlled trials were included. Using the Cochrane Risk of Bias Tool 2, for the primary outcomes, 5 trials had an overall high risk of bias, and 6 trials had some concerns of bias. Most data were available on IF fermented with Bifidobacterium breve C50 and Streptococcus thermophilus (BB/ST). These formulas, compared with the standard IF, were safe and well tolerated. Postbiotic formulas with additional modifications (ie, formula fermented with BB/ST & prebiotics, partly fermented formula with BB/ST and prebiotics with or without modified milk fat, partly fermented antiregurgitation formula with BB/ST and prebiotics) were generally safe and well tolerated but did not offer clear benefits replicated in other studies. Only limited data were available on formula fermented with Lactobacillus paracasei CBA L74. CONCLUSIONS: IF with postbiotics evaluated so far are safe and well tolerated by infants who cannot be breastfed. No firm conclusion can, however, be reached regarding the clinical effects and benefit of one formula over another. It seems reasonable to discuss with healthcare providers current evidence regarding specific modifications in infant formulas and let them decide whether the expected benefits meet expectations and are worth the cost.

BACKGROUND: This guideline from the European Academy of Allergy and Clinical Immunology (EAACI) recommends approaches to prevent the development of immediate-onset / IgE-mediated food allergy in infants and young children. It is an update of a 2014 EAACI guideline. METHODS: The guideline was developed using the AGREE II framework and the GRADE approach. An international Task Force with representatives from 11 countries and different disciplinary and clinical backgrounds systematically reviewed research and considered expert opinion. Recommendations were created by weighing up benefits and harms, considering the certainty of evidence and examining values, preferences and resource implications. The guideline was peer-reviewed by external experts, and feedback was incorporated from public consultation. RESULTS: All of the recommendations about preventing food allergy relate to infants (up to 1 year) and young children (up to 5 years), regardless of risk of allergy. There was insufficient evidence about preventing food allergy in other age groups. The EAACI Task Force suggests avoiding the use of regular cow's milk formula as supplementary feed for breastfed infants in the first week of life. The EAACI Task Force suggests introducing well-cooked, but not raw egg or uncooked pasteurized, egg into the infant diet as part of complementary feeding. In populations where there is a high prevalence of peanut allergy, the EAACI Task Force suggests introducing peanuts in an age-appropriate form as part of complementary feeding. According to the studies, it appears that the most effective age to introduce egg and peanut is from four to 6 months of life. The EAACI Task Force suggests against the following for preventing food allergy: (i) avoiding dietary food allergens during pregnancy or breastfeeding; and (ii) using soy protein formula in the first 6 months of life as a means of preventing food allergy. There is no recommendation for or against the following: use of vitamin supplements, fish oil, prebiotics, probiotics or synbiotics in pregnancy, when breastfeeding or in infancy; altering the duration of exclusive breastfeeding; and hydrolysed infant formulas, regular cow's milk-based infant formula after a week of age or use of emollients. CONCLUSIONS: Key changes from the 2014 guideline include suggesting (i) the introduction of peanut and well-cooked egg as part of complementary feeding (moderate certainty of evidence) and (ii) avoiding supplementation with regular cow's milk formula in the first week of life (low certainty of evidence). There remains uncertainty in how to prevent food allergy, and further well-powered, multinational research using robust diagnostic criteria is needed.

BACKGROUND: Evidence from studies in adults documents that fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) may be triggers of symptoms in individuals with functional abdominal pain disorders (FAPDs). However, in children, the evidence is very limited. We aim to assess the effects of a low-FODMAP diet compared with a regular diet for the management of children with FAPDs. METHODS: We will perform a randomized, quadruple-blinded, controlled trial. Seventy-four children aged 8 to 18 years with a FAPD (Irritable Bowel Syndrome or Functional Abdominal Pain-Not Otherwise Specified), diagnosed according to the Rome IV criteria, will be randomly allocated to receive either a low-FODMAP diet or a regular diet for 4 weeks. The primary outcome will be the percentage of the responders, defined as the participants who have at least 30% improvement in abdominal pain intensity on a Visual Analogue Scale (VAS) during the last week of the trial compared with baseline, that is at least equal to the Reliable Change Index (≥ 25 mm change on VAS). Other outcomes will include changes in stool consistency, abdominal pain frequency, total scores on the Gastrointestinal Symptom Rating Scale, KIDSCREEN-10 Index and World Health Organization Five Well-Being Index, child's school attendance and parents' work absenteeism, and BMI-for-age z-score. Compliance, tolerability of the low-FODMAP diet, and adverse events also will be evaluated. Each FAPD subtype will be assessed separately. DISCUSSION: There is a need for high-quality evidence regarding the dietary management of children with FAPDs. This randomized controlled trial (RCT) of rigorous methodological design will help to establish the effectiveness, if any, of a low-FODMAP diet for the management of FAPDs in the pediatric population. The findings of this RCT will assist with the development of guidelines and influence the direction of further research. TRIAL REGISTRATION: NCT04528914 Data and protocol version identifier: 24/08/2020.

OBJECTIVE: To summarize evidence on the efficacy and safety of the use of extensively hydrolyzed formulas (EHFs) for the treatment of children with cow's milk allergy (CMA). DESIGN: Systematic review of randomized controlled trials (RCTs) per PRISMA guidelines. The risk of bias of included RCTs was assessed using the Cochrane Collaboration's risk of bias tool. In general, a narrative synthesis of the findings was performed. When sufficient data were available, a meta-analysis using the random-effect model was performed. DATA SOURCES: The Cochrane Library, MEDLINE, and EMBASE databases were searched up to February 2020. ELIGIBILITY CRITERIA: RCTs, including cross-over trials, assessing children of any age with any type of CMA that compared use of a formula containing extensively hydrolyzed bovine proteins (whey and/or casein) with use of any other formula for CMA management, were eligible for inclusion. Each type of EHF was evaluated separately. Outcome measures included allergic reactions (ie gastrointestinal, dermatological, and respiratory symptoms), growth, tolerance acquisition to cow's milk proteins, health-related quality of life, and safety. RESULTS: Fifteen trials reported in 18 publications (1285 children) fulfilled the inclusion criteria. The study findings were limited by numerous methodological issues, including differences in outcome measures and their definitions, lack of pre-specified protocols and/or trial registration, and poor reporting of adverse events, methods of sequence generation and allocation concealment. The EHF products evaluated to date appear to be well-tolerated by most children with CMA. However, published studies do not allow for any conclusion to be reached regarding the benefit of one formula over another formula intended for CMA management. CONCLUSIONS: This systematic review highlights the need for standardized treatment protocols, including an agreed-upon standardized set of outcomes that should be measured and reported in all clinical trials of specialized milk formula for the management of CMA.

BACKGROUND: This systematic review of ways to prevent immediate-onset/IgE-mediated food allergy will inform guidelines by the European Academy of Allergy and Immunology (EAACI). METHODS: The GRADE approach was used. Eleven databases were searched from 1946 to October 2019 for randomized controlled trials (and large prospective cohort studies in the case of breastfeeding). The studies included heterogeneous interventions, populations, and outcomes and so were summarized narratively. RESULTS: Forty-six studies examined interventions to reduce the risk of food allergy in infancy (up to 1 year) or early childhood. The following interventions for pregnant or breastfeeding women and/or infants may have little to no effect on preventing food allergy, but the evidence is very uncertain: dietary avoidance of food allergens, vitamin supplements, fish oil, probiotics, prebiotics, synbiotics, and emollients. Breastfeeding, hydrolyzed formulas, and avoiding cow's milk formula may not reduce the risk of cow's milk protein allergy; however, temporary supplementation with cow's milk formula in the first week of life may increase the risk of cow's milk allergy. Introducing well-cooked egg, but not pasteurized raw egg, from 4 to 6 months probably reduces the risk of hen's egg allergy. Introducing regular peanut consumption into the diet of an infant at increased risk beginning from 4 to 11 months probably results in a large reduction in peanut allergy in countries with a high prevalence. These conclusions about introducing peanut are based on moderate certainty evidence, from single trials in high-income countries. CONCLUSIONS: Sixty percent of the included studies were published in the last 10 years, but much still remains to be understood about preventing food allergy. In particular, there is a need to validate the potential benefits of early introduction of food allergens in a wider range of populations.
