Outdoor air pollution may disturb immune system development. We investigated whether gestational exposure to traffic-related air pollutants (TRAP) is associated with unstimulated cytokine profiles in newborns.

Data come from 235 newborns of the NELA cohort. Innate response-related cytokines (IL-6, IFN-α, IL1-β, and TNF-α), Th1-related (IFN-γ and IL-2), Th2-related (IL-4, IL-5, and IL-13), Th17-related (IL-17 and IL-23), and immunomodulatory cytokine IL-10 were quantified in the supernatant of unstimulated whole umbilical cord blood cells after 7days of culture using the Luminex technology. Dispersion/chemical transport modeling was used to estimate long-term (whole pregnancy and trimesters) and short-term (15days before delivery) residential exposures to traffic-related nitrogen dioxide (NO
), particulate matter (PM
and PM
), and ozone (O
). We fitted multivariable logistic regression, Bayesian kernel machine regression (BKMR), and weighted quantile sum (WQS) regression models.

NO
during the wchanges might influence immune system responses later in life.
A proportion of asthmatic children outgrow their disease by adulthood, but there are limited data on predictors for asthma persistence. This prospective study characterized the trajectory of spirometric indices and identified predictors for the persistence of childhood asthma.

Chinese asthmatic children aged 6-15years from pediatric allergy clinic underwent annual visits for ≥5years and until their adulthood. Pre-bronchodilator spirometry and anti-asthma medications were recorded at baseline and then at least annually. Asthma resolution was defined when patients were free from asthma symptoms and use of anti-asthma drugs for ≥2years. Logistic regression was used to identify predictors for asthma persistence. Generalized estimating equation was used to analyze longitudinal changes in lung function parameters in relation to asthma persistence.

181 asthmatic children aged [mean (SD)] 10.0 (2.7) years were followed for [mean (SD)] 12.5 (2.8) years. One third of them outgrew asthma during follow-up. Female was 3.36 times more likely to have persistent asthma. Inhaled corticosteroid (ICS) treatment ever and frequent asthma exacerbation (AE) predicted asthma persistence with respective odds ratios of 3.19 (95% confidence interval [CI] 1.44-7.09) and 3.05 (95% CI 1.39-6.68). Persistent asthma was inversely associated with baseline forced expiratory volume in 1-second (FEV
%) with an odds ratio of 0.96 (95% CI 0.93-1.00). Throughout follow-up, patients with persistent asthma had generally lower forced expiratory indices than those with asthma resolution. Children with persistent asthma experienced poorer lung function growth.

Female, ICS ever, and frequent AE predicted persistent asthma. Patients with persistent asthma had lower forced expiratory indices and poorer lung function growth into adulthood.

Children whose mothers have autoimmune disease may be at risk of developing immune-mediated disorders. We assessed the association between maternal autoimmune disease and risk of autoimmune disease, allergy, and cancer in offspring.

We analyzed a cohort of 1,011,623 children born in Canada between 2006 and 2019. We identified mothers who had autoimmune diseases and assessed hospitalizations for autoimmune disease, allergy, and cancer in offspring between birth and 14years of age. We estimated hazard ratios (HR) for the association of maternal autoimmune disease with child hospitalization in adjusted Cox regression models. We used within-sibling analysis to control for genetic and environmental confounders.

A total of 20,354 children (2.0%) had mothers with an autoimmune disease. Compared with no autoimmune disease, maternal autoimmune disease was associated with the risk of childhood hospitalization for autoimmune disease (HR 1.96, 95% CI 1.66-2.31) and allergy (HR 1.30, 95% CI 1.21-1.40), but was not sroducts is not likely a direct cause of immune-mediated disease in children.
While exposure to environmental greenness in childhood has shown mixed associations with the development of allergic disease, the relationship with food allergy has not been explored. We investigated the association between exposure to environmental greenness and challenge-confirmed food allergy in a large population-based cohort.

The HealthNuts study recruited 5276 12-month-old infants in Melbourne, Australia, who underwent skin prick testing to peanut, egg, and sesame; infants with a detectable wheal underwent food challenges to determine food allergy status. Environmental greenness was estimated using the normalized difference vegetation index (NDVI) for five buffer zones around the infant's home address at the home, 100m, 500m, 800m, and 1600m radial distances. see more Environmental greenness was categorized into 3 tertiles and mixed effects logistic regression models quantified the association between greenness and the risk of food allergy, adjusting for confounding and accounting for clustering at the neigh(PM2.5) also modified the associations between environmental greenness and food allergy, with associations present in high air pollution areas but not low (p for interaction at 100 m 0.05 for peanut and 0.06 for egg allergy.) CONCLUSION Increased exposure to environmental greenness in the first year of life was associated with an increased risk of food allergy. Increased greenness may correlate with higher pollen levels which may trigger innate immune responses skewing the immune system to the Th2-dependent allergic phenotype; additionally, some pollen and food allergens are cross-reactive. Given the mixed data on greenness and other allergies, the relationship appears complex and may also be influenced by confounding variables outside those that were measured in this study.
Human milk oligosaccharides (HMOs) have several biological functions. Yet, very few studies have investigated the effect of HMOs on the development of allergies and even fewer on their specific associations with atopic dermatitis (AD) during early childhood.

This study investigated whether individual HMO concentrations, measured at two time points of lactation, were associated with reported diagnosis of AD in children up to twoyears of age.

Outcome data were available for HMOs measured in human milk samples collected at 6weeks (n=534) and 6months (n=356) of lactation. Associations of HMOs with AD, ascertained from parents and pediatricians at ages one and two years, were assessed in crude and adjusted logistic regression models.

Few associations were statistically significant at the conventional level (p<.05), for example, 6-week Lacto-N-neotetraose with 2-year AD [OR 95%CI 0.82 (0.66, 1.00)] and 6-month 3'-sialyllactose among non-secretor mothers with 1-year AD [2.59 (1.53, 6.81)]. Importantly, achese results should be interpreted with caution. The specific HMOs for which we show plausible associations at conventional level may warrant further research and investigation.
Atopic dermatitis (AD) occurs in exclusively breastfed infants. As fatty acids have some immunomodulatory effect, we aimed to investigate the influence of fatty acid compositions in breast milk (BM) on the development of AD in exclusively breastfed infants.

We enrolled two- to four-month-old exclusively breastfed infants. The objective SCORing Atopic Dermatitis (objSCORAD) was evaluated. The lipid layer of BM was analyzed by gas chromatography for fatty acid levels. Medical charts were reviewed.

Forty-seven AD infants and 47healthy controls were enrolled. The objSCORAD was 20.5±1.7 (shown as mean±SEM) in the AD group. The age, sex, parental atopy history, and nutrient intake of mothers were not significantly different between two groups. The palmitate and monounsaturated fatty acid (MUFA) levels in BM positively correlated with objSCORAD, while caprylate, acetate, and short-chain fatty acid (SCFA) levels negatively correlated with objSCORAD (p=.031, .019, .039, .013, .022, respectively). However, the butyrate levels in BM were not significantly different. The caprylate and acetate levels in BM were significantly associated with the presence of infantile AD (p=.021 and .015, respectively) after adjusting for age, sex, parental allergy history, MUFA, palmitate, and SCFA levels in BM. ObjSCORAD in infancy was significantly associated with persistent AD (p=.026) after adjusting for age, sex, parental atopy history, caprylate, palmitate, MUFA, acetate, and SCFA levels in BM.

Caprylate and acetate levels in BM for exclusively breastfed infants were negatively associated with objSCORAD. Lower caprylate and acetate in BM might be the risk factors for infantile AD, while butyrate in BM was not associated with infantile AD.

While children usually experience a mild course of COVID-19, and a severe disease is more common in adults, the features, specificities, and functionality of the SARS-CoV-2-specific antibody response in the pediatric population are of interest.

We performed a detailed analysis of IgG antibodies specific for SARS-CoV-2-derived antigens S and RBD by ELISA in 26 SARS-CoV-2seropositive schoolchildren with mild or asymptomatic disease course, and in an equally sized, age- and gender-matched control group. Furthermore, a detailed mapping of IgG reactivity to a panel of microarrayed SARS-CoV-2 proteins and S-derived peptides was performed by microarray technology. The capacity of the antibody response to block RBD-ACE2 binding and virus neutralization were assessed. Results were compared with those obtained in an adult COVID-19 convalescent population.

After mild COVID-19, anti-S and RBD-specific IgG antibodies were developed by 100% and 84.6% of pediatric subjects, respectively. No difference was observed in regards to symptoms and gender. Mounted antibodies recognized conformational epitopes of the spike protein and were capable to neutralize the virus up to a titer of ≥80 and to inhibit the ACE2-RBD interaction by up to 65%. SARS-CoV-2-specific IgG responses in children were comparable to mildly affected adult patients.

SARS-CoV-2 asymptomatic and mildly affected pediatric patients develop a SARS-CoV-2-specific antibody response, which is comparable regarding antigen, epitope recognition, and the ability to inhibit the RBD-ACE2 interaction to that observed in adult patients after mild COVID-19.

There are a limited number of validated questionnaires available for use in the clinical screening for allergic rhinitis (AR) in children ≤3years old. We developed a novel self-reported questionnaire and assessed its accuracy and reliability.

After establishing a pool of items, which were screened by experts, the Young Children Allergic Rhinitis Questionnaire (YCAR-Q) was administered to a birth cohort in the Shunyi District (Beijing, China). The electronicversion of the YCAR-Q was distributed through the online community. Children were invited to visit a physician for examination. The diagnostic criteria included symptoms, physical examination findings, and specific serum immunoglobulin E tests. Each item on the questionnaire was evaluated, and the questionnaire's internal consistency, content validity, criterion-related validity, and diagnostic accuracy were assessed.

The six-item YCAR-Q was distributed to 7423 parents, and 3037valid questionnaires were recovered. In total, 1521 children visited a physician for examination, of which 82 were found to have AR.
