Summary: This study compared the bone parameters of adolescents with persistent cow's milk allergy (CMA) with those of healthy adolescents. Adolescents with CMA had compromised bone parameters (lower bone mineral density, impaired trabecular microarchitecture, and lower bone strength). Partial exclusion diet was associated with better bone parameters than total exclusion diet. Background: Persistent immunoglobulin E (IgE)–mediated cow's milk allergy (CMA) may impair bone parameters and increase the risk of fractures. High-resolution peripheral quantitative computed tomography (HR-pQCT) is a novel methodology that not only assesses trabecular and cortical bone compartments and volumetric density measurements, but also evaluates bone microarchitecture and estimates biomechanical properties through finite element analysis (FEA). Both HR-pQCT and bone strength parameters derived from FEA have shown a strong correlation with fracture risk. Purpose: To assess the bone density, microarchitecture, and bone strength of adolescents with persistent IgE-mediated CMA (IgE-CMA). Methods: This was an observational, cross-sectional study with female adolescents with persistent IgE-CMA and healthy control participants matched by female sex and sexual maturation. Bone parameters were assessed by areal bone mineral density (aBMD) through dual-energy X-ray absorptiometry (DXA), bone microarchitecture by HR-pQCT at the radius and tibia, and laboratory markers related to bone metabolism. Results: The median age of adolescents with persistent IgE-CMA (n = 26) was 13.0 years (interquartile range (IQR) 11.4–14.7) and of healthy control participants (n = 28) was 13.6 years (IQR 11.9–14.9). Adolescents with IgE-CMA ingested 27.4% less calcium (p = 0.012) and 28.8% less phosphorus (p = 0.009) than controls. Adolescents with IgE-CMA had lower bone mineral content (BMC) (38.83 g vs. 44.50 g) and aBMD (0.796 g/cm2 vs. 0.872 g/cm2) at lumbar spine, and lower BMC (1.11 kg vs. 1.27 kg) and aBMD (0.823 g/cm2 vs. 0.877 g/cm2) at total body less head (TBLH) (p < 0.05). However, Z-scores BMC and Z-scores aBMD at lumbar spine and TBLH, when adjusted for Z-score height/age, were not significantly different between the groups. Moreover, CMA adolescents had lower bone strength at the distal tibia (S 169 kN/mm vs. 194 kN/mm; F Load 8030 N vs. 9223 N) (p < 0.05). Pairing of groups by the presence of menarche showed compromised parameters at the tibia—lower total volumetric BMD (Tt.vBMD) (293.9 mg HA/cm3 vs. 325.9 mg HA/cm3) and trabecular vBMD (Tb.vBMD) (170.8 mg HA/cm3 vs. 192.2 mg HA/cm3), along with lower cortical thickness (Ct.th) (1.02 mm vs. 1.16 mm) and bone strength (S 174 kN vs. 210 kN; F Load 8301 N vs. 9950 N)—and at the radius (S 61 kN/mm vs. 71 kN/mm; F Load 2920 N vs. 3398 N) (p < 0.05) among adolescents with IgE-CMA. Adolescents with IgE-CMA on a total exclusion diet (n = 12) showed greater impairment of bone features than those on a partial exclusion diet (n = 14), with lower lumbar spine Z-score BMC (− 0.65 vs. 0.18; p = 0.013), lumbar spine trabecular bone score (TBS) (1.268 vs. 1.383; p = 0.005), Z-score TBS (0.03 vs. 1.14; p = 0.020), TBLH Z-score BMC (− 1.17 vs. − 0.35; p = 0.012), TBLH Z-score aBMD (− 1.13 vs. − 0.33; p = 0.027), Tt.vBMD at the tibia (259.0 mg HA/cm3 vs. 298.7 mg HA/cm3; p = 0.021), Ct.th at the tibia (0.77 mm vs. 1.04 mm; p = 0.015) and Ct.th at the radius (0.16 mm vs. 0.56 mm; p = 0.033). Conclusion: Adolescents with persistent IgE-CMA had lower aBMD and compromised microarchitecture (impaired trabecular microarchitecture and lower bone strength). Adolescents on a partial exclusion diet had better bone parameters than those on a total exclusion diet. [ABSTRACT FROM AUTHOR]

Purpose: Cow’s milk protein allergy (CMPA) is a common condition in infants, but little is known about healthcare providers’ clinical experience treating infants with CMPA. To address this gap, we analyzed prospectively collected data from healthcare providers (HCPs) who treated infants under six months old with suspected CMPA using hypoallergenic formulas. The study focused on a commercial extensively hydrolyzed formula containing Lactobacillus rhamnosus GG (ATCC53103) (eHF-LGG) or a commercial amino acid formula (AAF). Methods: In this secondary analysis of prospectively collected survey data, 52 HCPs treated 329 infants under six months old with suspected CMPA using hypoallergenic formulas. A series of two de-identified surveys per patient were collected by HCPs to assess short-term symptom relief in the patients and HCP’s satisfaction with the management strategies. The initial survey was completed at the initiation of treatment of CMPA, and the second survey was completed at a follow-up visit. Results: The majority of HCPs (87%) in the study were general pediatricians, and most saw 2 to 10 CMPA patients weekly. Results showed that clinicians reported satisfaction with treatment in 95% of patients in the EHF cohort and 97% of patients in the AAF cohort and achieved expected clinical results in 93% and 97% of patients using eHF and AAF, respectively. Furthermore, few patients were switched from the hypoallergenic formula once initiated. Conclusion: The study provides new insights into HCP perspectives on treating infants with CMPA and supports using hypoallergenic formulas to manage this condition. However, additional prospective controlled studies are needed to confirm these initial findings. [ABSTRACT FROM AUTHOR]

Background. Routine immunisation, one of the most successful public health initiatives, has significantly decreased infectious disease-related mortality and morbidity. Family physicians in Turkey avoid administering vaccines to children who have food allergies and instead refer them to a hospital setting. Objectives. In this study, we aimed to evaluate the approaches of family physicians when applying vaccines to children with diagnosed or suspected food allergies according to the national vaccination schedule. Material and methods. This study was carried out between 01.07.2021 and 31.08.2021 with family physicians in the Ankara province. Using questionnaire, the participants were questioned about their sociodemographic characteristics, their vaccination approaches towards patients with diagnoses or suspicions of food allergies and their personal experiences. Results. A total of 184 family physicians participated in this study, and 82.6% of them stated that they were hesitant about the administrations of vaccines to children with diagnosed or suspected food allergies. Regarding the administration of vaccines, the most concerning food allergies involved eggs (71.7%) and cow’s milk (15.8%). The vaccinations they were mainly concerned about were determined as the measles-rubella-mumps (MMR) (83.7%) and measles (46.7%) vaccines in a suspected or diagnosed presence of an egg allergy and/or cow’s milk allergy, respectively. Conclusions. This study showed that the surveyed family physicians are hesitant of vaccinating children with diagnoses or suspicions of food allergies and see themselves as intermediately qualified. This can cause referrals of children to higher-level centres for vaccinations, delays in vaccinations and parental vaccine hesitancies. [ABSTRACT FROM AUTHOR]

Cow's milk allergy (CMA) is one of the most common food allergies in the first years of life, with worldwide prevalence estimated to range from 2% to 5%. While the majority of children with CMA will eventually develop tolerance to cow's milk proteins (it is estimated that >75% of children with CMA develop tolerance to cow's milk proteins by the age of 3 years, and >90% develop tolerance by the age of 6 years), the selection of an appropriate cow's milk (CM) alternative for those with CMA is vital to ensure adequate growth and development during childhood. The increasing number of CM alternative products on the commercial market with markedly different nutritional content and micronutrient fortification adds a layer of complexity that can be challenging for both families and clinicians to navigate. This article aims to provide guidance and clarity to Canadian paediatricians and primary care clinicians on recommending the most appropriate, safe, and nutritionally optimal CM alternatives for individuals with CMA, and beyond.

The global prevalence of allergies is on the rise. Food allergies are of special concern among children under 5 years of age, leading to morbidity and mortality. Though the standard management is avoidance, probiotics are being used widely to prevent and treat food allergies. We aimed to determine the effect of probiotics as a therapeutic option for controlling food and cow’s milk allergy among children under 5 years of age. A systematic search of electronic medical literature databases was conducted. We included all eligible randomized controlled trials available from inception until May 2021. The primary outcome of interest was the relief of allergic symptoms, while the secondary outcome was the induction of tolerance. Two investigators undertook the literature search, screening, data extraction, and quality appraisal independently. Data analysis and synthesis were performed using STATA 14 software. Subgroup analysis was performed for the duration of use and follow-up, and the age category of children included in the outcome were done. Twenty trials involving 4043 pediatric patients with food allergies were included in the review. Subgroup analysis also revealed that probiotics were effective in treating food allergies across the various subgroups included in the model. Around 15 trials reported our primary outcome, relief of symptoms, as a binary variable, which was pooled to obtain a risk ratio of 0.86 (95% confidence interval [CI], 0.77–0.95), with very low heterogeneity (I2 7.7%). Six trials were included for the secondary outcome of interest, which gave an imprecise pooled estimate of 1.29 (95% CI, 0.98–1.70) with significant heterogeneity (I2 77%). Thus, we conclude that probiotics can serve as a vital therapeutic option in tackling food allergies among children less than 5 years of age. Further larger studies exploring the effectiveness of individual strains and their safety pattern are essential. [ABSTRACT FROM AUTHOR]

Objectives: To review the evidence pertaining to the association between cow’s milk protein allergy and recurrent acute otitis media and otitis media with effusion. Methods: The CENTRAL, Web of Science, EMBASE, MEDLINE, LILACS databases, and gray literature were searched. Results: Four studies were included, identifying the prevalence rates: 0.2% of delayed speech due to chronic otitis media with effusion in 382 children with cow’s milk protein allergy, 10.7% of cow’s milk protein allergy in 242 children who underwent ENT procedures, 40% of cow’s milk protein allergy in 25 children with recurrent otitis media with effusion and higher tendency to otitis media in children with cow’s milk protein allergy of 186 children (1.5 + 0.6 vs. 0.4 + 0.1; p
