Criteria for the suspicion and diagnosis of acute food protein-induced enterocolitis syndrome.

Over the past decades, several panels of criteria have been proposed for the diagnosis of acute food protein-induced enterocolitis syndrome (FPIES). However, none of them have been validated by a prospective study. Such a study is not easy to carry out, because even the children who most of us would certainly believe to be suffering from acute FPIES, possibly serious, should be subject to oral food challenge (OFC). Moreover, the presence of different phenotypes of the acute FPIES may mean that some of them do not fit into any of the above criteria panels. Particularly, Vazquez-Ortiz et al. reported that milder cases (1/4 in their Southern European cohort) might not be captured by the 2017 Consensus diagnostic criteria, which are the most shared till date. Those authors, as well as all interested researchers, claim for accurate diagnostic bio-markers which, however, are not available at the moment

Potential Application of Lung Ultrasound in Children with Severe Uncontrolled Asthma: Preliminary Hypothesis Based on a Case Series

: In recent years, lung ultrasound (LUS) has been increasingly used for the diagnosis of respiratory diseases in both adult and pediatric patients. However, asthma is a field in which the use of LUS is not yet well defined, or is in development. In the following case series, we describe clinical, laboratory, and radiological results, as well as detailed lung ultrasound findings of six children with asthma: some of them with acute asthma attack and with inadequately controlled allergic asthma or childhood asthma; others with acute asthma and allergic or infantile asthma adequately controlled by preventive therapy. Finally, we describe the clinical, laboratory, and imaging parameters of a child with severe allergic asthma in the absence of exacerbation. In these cases, albeit at different times, LUS played an important role in both the initial diagnostic process and follow-up. It also showed different ultrasound features depending on the severity of the individual asthma based on the type of asthmatic phenotype and control of it

Functional constipation related to cow's milk allergy in children: A management proposal.

Functional constipation (FC) is one of the most common disorders in childhood and has a neg-ative impact on the quality of life of children. Scientific evidence regarding a causal relation-ship between FC and cow's milk allergy is controversial, as it is also reported by the latest European Society for Paediatric Gastroenterology, Hepatology and Nutrition-North American Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN–NASPGHAN) rec-ommendations. In the case of FC, routine allergometric tests are not recommended and the cows' milk-free diet is only proposed in the case of laxative-resistant constipation and only following the advice of an expert. Instead, after a careful review of the literature and in view of the many clinical cases encountered in our clinical practice, we believe that it is useful to propose cows' milk-free diet as first line for the treatment of FC at least in pre-school children and in children with a personal or family history of atopy or with a previous diagnosis of cow's milk protein allergy

Asthma Control Test and Bronchial Challenge with Exercise in Pediatric Asthma

Background: Poor asthma control can lead to exercise-induced bronchoconstriction (EIB), but the relationship between subjective disease control and EIB is unclear. No studies have compared asthma control test (ACT) scores of children with those of their parents regarding EIB. We assessed whether ACT scores predict the occurrence of EIB in two age groups. We also evaluated ACT scores and objective measures as explanatory variables for airway response to exercise. Methods: Patients (71 aged <12 years, 93 aged 6512 years) and their parents completed an ACT questionnaire separately. Current therapy, skin prick testing and spirometry at baseline and after exercise were assessed. EIB was defined as a fall in FEV1 of at least 12% from baseline. Sensitivity and specificity for cut-off values of ACT scores predictive of EIB were plotted, and the Area Under Curve (AUC) was described. Results: Atopy and current therapy were similarly frequent. EIB was observed in 23.9% of children aged <12 years and in 33.3% aged 6512 years. EIB occurrence in subjects previously scored as having full control (25), partial control (20\u201024) and no control (<20) varied according to the age group and responder. Percentages of EIB cases increased as ACT scores decreased in children aged 6512 years alone (child ACT scores, 25: 21.9%, 20-24: 31.1%, <20: 62.5%, p=0.017). Plots for ACT scores as predictors of EIB yielded low non\u2010significant AUC values in children aged <12 years; by contrast, moderate AUC values emerged in children aged 6512 years (child: 0.67, p=0.007; parent: 0.69, p=0.002). Sensitivity of ACT scores below 20 as a predictor of EIB was low in older children (child: 32.3%, parent: 22.6%), whereas specificity was high (child: 90.3%, parent: 93.5%). Multiple regression analysis with percent fall in FEV1 as dependent variable included FEV1/FVC%, ACT child score and gender in the prediction model ( r=0.42, p=0.000). Conclusion: ACT scores are a more effective means of excluding than confirming EIB in asthmatic patients aged 6512 years; their predictive value decreases in younger patients. ACT scores together with lung function may help to predict airway response to exercise. New tools for pediatric asthma assessment may optimize this association

International consensus guidelines for the diagnosis and management of food protein–induced enterocolitis syndrome: Executive summary—Workgroup Report of the Adverse Reactions to Foods Committee, American Academy of Allergy, Asthma & Immunology

Food protein-induced enterocolitis (FPIES) is a non-IgE cell- mediated food allergy that can be severe and lead to shock. Despite the potential seriousness of reactions, awareness of FPIES is low; high-quality studies providing insight into the pathophysiology, diagnosis, and management are lacking; and clinical outcomes are poorly established. This consensus document is the result of work done by an international workgroup convened through the Adverse Reactions to Foods Committee of the American Academy of Allergy, Asthma & Immunology and the International FPIES Association advocacy group. These are the first international evidence-based guidelines to improve the diagnosis and management of patients with FPIES. Research on prevalence, pathophysiology, diagnostic markers, and future treatments is necessary to improve the care of patients with FPIES. These guidelines will be updated periodically as more evidence becomes available

Food Protein-Induced Enterocolitis Syndrome: Proposals for New Definitions

Acute food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated allergy and is characterized by repetitive profuse vomiting episodes, often in association with pallor, lethargy, and diarrhea, presenting within 1&ndash;4 h from the ingestion of a triggering food. In 2017, the international consensus guidelines for the diagnosis and management of FPIES were published. They cover all aspects of this syndrome, which in recent decades has attracted the attention of pediatric allergists. In particular, the consensus proposed innovative diagnostic criteria. However, the diagnosis of acute FPIES is still currently discussed because the interest in this disease is relatively recent and, above all, there are no validated panels of diagnostic criteria. We propose some ideas for reflection on the diagnostic and suspicion criteria of acute FPIES with exemplary stories of children certainly or probably suffering from acute FPIES. For example, we believe that new definitions should be produced for mild forms of FPIES, multiple forms, and those with IgE-mediated symptoms. Moreover, we propose two clinical criteria to suspect acute FPIES and to refer the child to the diagnostic oral food challenge

Risk factors for severe pediatric food anaphylaxis in Italy.

BACKGROUND: Little is known about the cause of food-induced anaphylaxis in children or about the factors that might affect its clinical severity. OBJECTIVE: The aim of this study was to investigate the cause of food-induced anaphylaxis in children in Italy and to identify factors that could influence the appearance of symptoms and the severity of anaphylaxis. METHODS: One hundred and sixty-three children with anaphylaxis consecutively attending 29 outpatient allergy clinics throughout Italy were enrolled in this prospective study. Information about past anaphylaxis episodes was collected with a standardized questionnaire. Food sensitization was evaluated by skin-prick test. RESULTS: A clinical history of asthma increased the risk of wheezing [odds ratio (OR) 2.2; 95% confidence interval (CI) 1.1-4.5] and respiratory arrest (OR 6.9; 95% CI 1.4-34.2). A clinical history of chronic/relapsing gastrointestinal symptoms increased the risk of vomiting (OR 2.1; 95% CI 0.9-4.3), hypotension (OR 7.9; 95% CI 1.9-32.0), and bradycardia/cardiac arrest (OR 9.2; 95% CI 0.9-91.3). The severity of present and previous episodes was similar only in patients with mild or moderate anaphylaxis. Peanut and egg were the most frequent causes of severe anaphylaxis. CONCLUSIONS: A clinical history of asthma and chronic/relapsing gastrointestinal symptoms (probably linked to food allergy) may predict the development of respiratory and gastrointestinal symptoms and the severity of anaphylaxis
