Eosinophil-derived neurotoxin levels in early childhood and association with preschool asthma - A prospective observational study. Clin Exp Allergy 2023; 53:1198-1211. [PMID: 37795650 DOI: 10.1111/cea.14409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 09/01/2023] [Accepted: 09/19/2023] [Indexed: 10/06/2023]
Abstract
INTRODUCTION Eosinophil-derived neurotoxin (EDN) is related to childhood asthma, while normal values are lacking. We aimed to document serum EDN levels at 1 and 3 years in general and in non-atopic children, and explore if EDN levels differed by sex or were associated with preschool asthma at 3 years. METHODS From the PreventADALL birth cohort, we included 1233 children with EDN analysed using ImmunoCAP at 1 and/or 3 years. Non-atopic children had no history of wheeze, asthma, allergic sensitization or atopic dermatitis. Preschool asthma was defined as having ≥3 episodes of bronchial obstruction between 2 and 3 years, plus doctor diagnosed asthma and/or asthma medication use by 3 years. The upper limit of normal (ULN) of EDN was defined as the 95th percentile. With Youden Index we calculated EDN cut-off levels for risk of preschool asthma. RESULTS The overall median (ULN) EDN levels were 27.4 (121) μg/L at 1 year (n = 787), and 20.1 (87.8) μg/L at 3 years (n = 857). Non-atopic children had EDN levels of 24.0 (107) μg/L at 1 year (n = 147), and 17.3 (84.6) μg/L at 3 years (n = 173). EDN levels were higher in boys compared to girls; 32.0 (133) versus 24.5 (97.0) μg/L at 1 year, and 20.9 (96.3) versus 19.0 (72.4) μg/L at 3 years. Preschool asthma was observed in 109/892 (12.2%) children. Higher EDN levels at 1 (>26.7 μg/L) and 3 (≥20.5 μg/L) years were associated with preschool asthma; adjusted OR (95% CI) 2.20 (1.09, 4.41) and 4.68 (2.29, 9.55), respectively. CONCLUSION AND CLINICAL RELEVANCE We report EDN values in early childhood, demonstrating higher levels at 1 compared to 3 years and in boys compared to girls at both ages. Higher EDN levels at both ages were associated with preschool asthma. However, EDN cut-off levels for preschool asthma were overall lower than the ULN of non-atopic children, limiting translation into clinical practice.

Abstract
Introduction: Patients with food protein-induced enterocolitis syndrome (FPIES) have elevated thymus and activation-regulated chemokine (TARC) levels in the acute phase. However, to the best of our knowledge, no study has evaluated TARC levels in the acute phase of immunoglobulin E-dependent food allergy (IgE-FA). If TARC elevation is a specific response to FPIES among FAs, TARC measurement may help distinguish between FPIES and IgE-FA. Thus, we investigated acute phase TARC levels in patients with FPIES and IgE-FA. Methods: Thirty-one episodes in 16 patients with FPIES and 20 episodes (13 were anaphylaxis) in 20 patients with IgE-FA were included. Patients with eczema were excluded. Serum TARC levels within 6 h of allergic reaction onset and age-adjusted TARC ratios (TARC levels divided by age-specific normal TARC values) were compared between the groups. Results: The median age was 1.1 and 3.6 years in the FPIES and IgE-FA groups, respectively (P < 0.001). The median (range) serum TARC (pg/mL) levels were significantly higher in the FPIES group than in the IgE-FA group [1,283 (410-3,821) versus 377 (109-1,539); P < 0.001]. The median (range) age-adjusted TARC ratios were also significantly higher in the FPIES group [2.56 (0.57-7.86) versus 1.08 (0.15-2.17); P < 0.001]. The area under the curve (AUC) for TARC to distinguish FPIES from IgE-FA was 0.926, and the AUC for the age-adjusted TARC ratio was 0.850. The odds ratio for FPIES diagnosis per 1,000 pg/mL increase in TARC was 31.6 (P = 0.002), and the odds ratio adjusted by age was 17.1 (P = 0.016). Conclusion: Acute phase TARC levels were higher in patients with FPIES than in patients with IgE-FA. The increase in acute phase TARC levels was considered to be a specific response to FPIES among FAs. Measurement of TARC levels in the acute phase may help differentiate FPIES from IgE-FA.

Abstract
Biomarker studies are becoming increasingly interesting for many fields of
medicine. The use of biomarkers in medicine is involved in detecting diseases and
supporting diagnosis and treatment decisions. New research and new discoveries on the
molecular basis of the disease show that there may be a number of promising new
biomarkers for use in daily clinical practice. Clinical trials in children lag behind adult
research both in quality and quantity. The number of biomarkers validated to optimize
pediatric patient management is limited. In the pathogenesis of many diseases, it should
not be extrapolated to the pediatric clinical setting, taking into account that biomarkers
that are effective in adults are clearly different in children and that ontogeny directly
affects disease development and therapeutic response in children. The search for ideal
biomarkers or markers that can make an early and definitive diagnosis in neonatal
sepsis is still ongoing. The ideal biomarker for pediatric diseases should be costeffective,
noninvasive, applicable to pediatric specific diseases, and its results should
correspond to age-related physiological changes. Lactate, troponin and B-type
natriuretic peptide are valuable biomarkers in the evaluation and management of
critically ill children with cardiac disease. Tumor markers in children are biochemical
substances used in the clinical treatment of pediatric tumors and to detect the presence
of cancer (regression or progression). In this chapter, current and brief information
about biomarkers and their clinical applications used in the diagnosis and monitoring of
pediatric diseases is presented.;

Abstract
Chemokine (C-C motif) ligand 17 (CCL17) is a pro-allergic factor: high CCL17 levels in cord blood (CB) precede later allergic predisposition. Short-chain fatty acid (SCFA) treatment during pregnancy has been shown to protect mouse pups against allergic diseases. The maternal microbial metabolome during pregnancy may affect fetal allergic immune responses. We therefore examined the associations between CB CCL17 and gut SCFA levels in healthy pregnant Japanese women. CB CCL17 serum levels at birth, and maternal non-specific IgE levels in maternal sera at 32 weeks of gestation were measured. Maternal stool samples were collected at 12 (n = 59) and 32 (n = 58) weeks of gestation for gut microbiota analysis, based on barcoded 16S rRNA sequencing and metabolite levels. The CB CCL17 levels correlated negatively with butyrate concentrations and positively with isobutyrate at 12 weeks; CB CCL17 correlated positively with valerate and lactate at 32 weeks. Similarly, butyrate levels correlated negatively with maternal non-specific IgE levels, whereas the lactate concentration correlated positively with IgE levels. At 32 weeks, the Shannon diversity index (SDI) of Firmicutes and Proteobacteria correlated negatively with CB CCL17 levels, while those of the total microbiota correlated positively with the CB CCL17 levels. These metabolites may alter fetal immune responses. This study provides the first link between maternal metabolites during pregnancy and the risk of allergic diseases in human offspring.

Abstract
BACKGROUND Post-emetic elevation in thymus and activation-regulated chemokine (TARC) levels has been reported in patients with food protein-induced enterocolitis syndrome (FPIES); however, no studies have investigated differences in TARC levels between FPIES and other diseases. OBJECTIVES We evaluated the clinical usefulness of TARC measurement in differentiating between FPIES and infectious gastroenteritis. METHODS This study included 8 patients with solid-food FPIES (FPIES group; hen's egg [n = 6], rice [n = 1], and short-neck clam [n = 1]; a total of 11 episodes necessitating emergency department visit or positive result of oral food challenge test) and 17 patients with infectious gastroenteritis (control group), and all patients had no eczema. Post-emetic serum TARC levels and modified TARC levels (serum TARC value - normal mean for each age) were compared between the 2 groups. RESULTS The median (range) ages for the FPIES and control groups were 0.7 (0.5-6.2) and 1.8 (0.1-4.4) years, respectively (p > 0.05). In the FPIES and control groups, median (range) TARC levels were 2,911 (1,062-7,816) and 600 (277-2,034) pg/mL, and median (range) modified TARC levels were 2,204 (355-7,109) and 129 (0-1,314), respectively. The TARC and modified TARC levels were significantly higher in the FPIES group than in the control group (p < 0.001 for both). CONCLUSION In the absence of eczema, post-emetic serum TARC levels might be a potential diagnostic biomarker for distinguishing FPIES from infectious gastroenteritis.

Abstract
INTRODUCTION Allergic rhinitis (AR) is a global health problem in adults as well as the younger population, continuously increasing and posing a significant problem for patients, health care systems and economies. For the younger population, some aspects differ from treatment of adults, namely, prevention, compliance and adherence. AREAS COVERED This narrative review summarizes all the pharmacotherapeutic options with special focus on the pediatric population. Moreover, it elucidates prevention strategies as well as future developments of AR treatment. Currently, symptomatic therapy in the form of steroids and antihistamines is applied topically and systemically where steroids need to be administered with caution and for a very short term. The only disease-modifying and causal treatment is allergen immunotherapy administered sublingually and subcutaneously. Future and current novel therapeutic options are human monoclonal antibodies. EXPERT OPINION The greatest potential for future developments currently lie in allergen immunotherapy and here in different routes of administration and modification of (recombinant) allergens as well as immune-modulating adjuvants and nanoparticles. Secondly, monoclonal antibodies are promising molecules blocking and/or interfering with up- and downstream immune mechanisms. Another important aspect lies in prevention of allergic sensitization and disease progression through both AIT and biologics which is particularly true for the pediatric population.

Abstract
Background The underlying cellular mechanisms causing adverse reactions to food are complex and still not fully understood. Therefore, in this study we aimed to identify functional and/or phenotypical immune cell signatures characteristic for adult patients reporting adverse reactions to food. By mass cytometry, we performed high-dimensional profiling of peripheral blood mononuclear cells (PBMC) from adult patients reporting adverse reactions to food and healthy controls. The patients were grouped according to sIgE-positive or sIgE-negative serology to common food and inhalant allergens. Two broad antibody panels were used, allowing determination of major immune cell populations in PBMC, as well as activation status, proliferation status, and cytokine expression patterns after PMA/ionomycin-stimulation on a single cell level. Results By use of data-driven algorithms, several cell populations were identified showing significantly different marker expression between the groups. Most striking was an impaired frequency and function of polyfunctional CD4+ and CD8+ T cells in patients reporting adverse reactions to food compared to the controls. Further, subpopulations of monocytes, T cells, and B cells had increased expression of functional markers such as CD371, CD69, CD25, CD28, and/or HLA-DR as well as decreased expression of CD23 in the patients. Most of the differing cell subpopulations were similarly altered in the two subgroups of patients. Conclusion Our results suggest common immune cell features for both patient subgroups reporting adverse reactions to food, and provide a basis for further studies on mechanistic and diagnostic biomarker studies in food allergy.

Abstract
Background Allergic rhinitis (AR) is one of the most common diseases globally and usually persists throughout life. In the present study, we aimed to determine whether the expression of inflammatory biomarkers has a relationship with the severity of allergic rhinitis and with comorbid asthma or other allergic diseases in children. Methods For diagnosis of AR, the skin prick test was performed to measure the responses to 18 allergens. Blood levels of eosinophils and immunoglobulin E (IgE) were examined. We classified the patients into 2 groups based on the severity of the condition as Group 1 [intermittent AR (IAR) or mild persistent AR (PAR)] and Group 2 (moderate to severe PAR). To determine the expression of inflammatory biomarkers, in serum and several biomarkers (caspase-1, IL-1β, CCL-11, CCL-24 and IL-33) were measured in the serum using enzyme-linked immunosorbent assay (ELISA). Additionally, we analyzed the correlation between clinical variables and the expression of biomarkers (eosinophils count, IL-1β and CCL-24) and the severity of AR. Results We found that eosinophils count, IL-1β, a marker of activation of inflammasomes, and CCL-24 were significantly increased in the moderate to severe PAR group (p = 0.008, p = 0.003, p = 0.039). Additionally, the expressions of eosinophil count, IL-1β and CCL-24 were significantly higher in patients with active asthmatic symptoms than in those without these conditions. On univariate analysis, allergic rhinitis in sibling, paternal allergic rhinitis, high expression of eosinophils count, IL-1β and CCL-24, history of active asthma and atopy correlated with severity of AR. Multivariate analysis showed only paternal allergic rhinitis and high expression of IL-1β as significant risk factors of moderate to severe PAR with 6.4 fold and 4.7 fold-increase in risk, respectively (p = 0.011 and p = 0.030). Conclusion In conclusion, this study provides the first evidence that an excessive release of biologically active IL-1β may promote inflammation in severe PAR. It demonstrates that IL-1β can be a biomarker for active allergic diseases such as AR, asthma, and atopy. Moreover, this finding suggests that IL-1B should be investigated as a therapeutic target in severe PAR and other allergic diseases.

Abstract
Juniperus chinensis, commonly Chinese juniper, has been used for treating inflammatory diseases. This study aimed to investigate anti-atopic dermatitis (AD) effects of standardized J. chinensis fruits extract on murine oxazolone- and 2,4-dinitrochlorobenzene (DNCB)-induced models of AD. Ear swelling, epidermis thickening, and eosinophils infiltration in the oxazolone-mediated dermatitis of BALB/c mice were significantly reduced upon topical application of J. chinensis fruits 95% EtOH extract (JCE). Besides, transdermal administration of JCE to SKH-1 hairless mice inhibited the development of DNCB-induced AD-like skin lesions by suppressing transepidermal water loss and improving skin hydration. Decreased total serum immunoglobulin E (IgE) and interleukin (IL)-4 levels could be observed in atopic dorsal skin samples of JCE-treated group. According to the phytochemical analysis, JCE was found to contain isoscutellarein-7-O-β-D-xyloside, cupressuflavone, and amentoflavone as main compounds. Therapeutic attempts with the J. chinensis fruits might be useful in the treatment of AD and related skin inflammatory diseases.
