Background: Food protein‐induced enterocolitis syndrome (FPIES) is a non-immunoglobulin E mediated food allergy that typically presents with repetitive emesis and may be associated with lethargy, marked pallor, hypotension, hypothermia, and/or diarrhea. Although many foods are known to cause FPIES, peanut-triggered FPIES is emerging due to changes in the feeding practice guidelines, which recommends early peanut introduction in infants. Objective: We aimed to characterize peanut-triggered acute FPIES cases in our pediatric population and to describe their attributes, treatment, and outcomes. We hypothesized that increases in the incidence of peanut-triggered FPIES coincided with implementation of the guidelines for early peanut introduction. Methods: A retrospective chart review was conducted of pediatric patients who presented to Phoenix Children’s Hospital Emergency Department and subspecialty clinics during a 6-year period (January 2013 to September 2019). Results: Thirty-three cases of patients with acute FPIES were identified, five of which were peanut triggered. In those patients with peanut-triggered FPIES, the median age for peanut introduction was 7 months (range, 5‐24 months). Two patients had positive peanut skin-prick test results. All five cases were identified in the past 2 years (2018 to 2019). No peanut-triggered reactions were documented in the preceding 4-year period (2013 to 2017). Conclusion: Peanut may be an emerging trigger of acute FPIES, coinciding with an earlier introduction of peanut in the infant diet after implementation of the new addendum guidelines for the prevention of peanut allergy. Oats and rice were the most common triggers of acute FPIES in our cohort. Further study will help clarify the significance and reproducibility of these findings.

Abstract Background Food protein-induced enterocolitis (FPIES), an entity previously thought to only affect children, has been increasingly described in adults. In this study, we report a Canadian cohort of 19 adolescents and adults with recurrent non-immunoglobulin E (IgE)-mediated gastrointestinal symptoms after crustacean ingestion, consistent with FPIES. Methods We conducted a retrospective chart review of patients in an outpatient allergy clinic from January 2005 to May 2020. Electronic records were searched using keywords for crustaceans and for symptoms consistent with FPIES. We included patients with gastrointestinal symptoms specifically to crustaceans on more than one occasion, who were 14 years or older at the time of index reaction. Exclusion criteria included symptoms suggestive of an IgE-mediated anaphylactic reaction or a likely alternative diagnosis. We identified 19 patients for our cohort who met the criteria. Results Our cohort was 68.4% female (13) and 32.6% (6) male. The average age at first reaction to crustaceans was 34 years old with a range of 14–68 years (median = 28 years; IQR = 32 years). Time from ingestion to beginning of symptoms ranged from 3 min to 6.5 h, with an average of 2.8 h (median = 2 h; IQR = 3.25 h). Duration of reaction ranged from less than a minute to over 48 h, with a mean of 9.4 h (median = 4 h; IQR = 7.75 h). Patients had 4.8 reactions on average; however, number of reactions ranged from 2 to 12.5 (median = 3, IQR = 3). All patients identified a “trigger” food in the crustacean group, and 12 subjects identified additional reactions to other seafood. Conclusions This case series will better characterize and advance our understanding of this disease entity in adults. There are key differences in the presentation of FPIES in adults compared to children, namely female predominance, difference in solid food trigger, and unpredictable time course. Future studies are needed to examine the pathophysiology and natural history of adult FPIES. Specific guidelines should be developed for the diagnosis and management in adults. Trial registration: retrospectively registered.

Abstrak: Prevalensi alergi makanan makin meningkat di seluruh dunia dan mengenai semua usia. Keparahan dan kompleksitas penyakit juga meningkat terlebih pada populasi anak. Terdapat beberapa jenis reaksi alergi yang dibahas: immunoglobulin E (IgE) mediated allergies and anaphylaxis, food triggered atopic dermatitis, eosinophilic esophagitis, dan non IgE mediated gastrointestinal food allergic disorders seperti food protein induced enterocolitis syndrome (FPIEs). Tes alergi, baik melalui kulit maupun IgE yang telah dikerjakan sekian lama masih dibebani dengan hasil positif palsu dan negatif palsu yang bermakna dengan manfaat terbatas pada beberapa alergi makanan. Selain menghindari, tidak terdapat terapi yang ampuh untuk alergi makanan. Berbagai imunoterapi telah dipelajari melalui jalur, subkutan, epikutan, oral dan sublingual yang hanya menghasilkan desensitisasi sementara dan dibebani dengan berbagai isu mengenai keamanannya. Agen biologik yang menghambat sitokin/interleukin (IL) dan molekul pada reaksi alergi makanan tampaknya merupakan pilihan yang menjanjikan. Anti IgE telah dipergunakan pada asma dan urtikaria kronis. Anti IL-4 dan IL-13 yang menghambat produksi IgE diindikasikan untuk dermatitis atopik. Anti eosinofil anti IL-5 berhasil menurunkan eksaserbasi asma. Berbagai agen biologik telah dipelajari untuk berbagai kondisi alergik dan imunologik, tetapi efektivitas dan kepraktisan terapi yang mahal ini untuk alergi makanan masih menjadi tanda tanya.Kata kunci: alergi makanan, reaksi alergi, terapi alergi makananAbstract: Food allergies have been increasing in prevalence for years affecting all ages. Disease severity and complexity have also increased, especially in the pediatric population. There are several types of reactions including: immunoglobulin-E (IgE) mediated allergies and anaphylaxis, food-triggered atopic dermatitis, eosinophilic esophagitis, and non IgE mediated gastrointestinal food allergic disorders such as FPIEs. Though allergy testing has been around for years, both skin and IgE testing are burdened by significant false positives and negatives, and are only useful in some food allergies. Avoidance is the sole therapy for food allergy. A variety of immunotherapies have been studied; subcutaneous, epicutaneous, oral, and sublingual. At best they only produce a temporary state of desensitization and have many safety issues. Examples of biologicals which block critical cytokines/interleukins (IL) in allergic conditions are Anti IgE, anti IL-4 and IL-13, and Anti eosinophils, Anti IL-5. Other biologicals are being studied for allergic conditions, but whether these expensive future treatments will be proven effective and practical in food allergy is unknown.Keywords: food allergy, allergic reaction, food allergy therapy

Background Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the pediatric population. The pathophysiology of AD is complex and not clearly understood. The role of lipoxin B4 (LXB4), an anti-inflammatory mediator, has not been sufficiently investigated in children with AD to our knowledge. Objective To compare the levels of serum LXB4 between children with AD and healthy controls.   Methods Three groups of children were enrolled in this study: a SPT-Pos group (skin prick test positive 21 subjects with AD), a SPT-Neg group (skin prick test negative 22 subjects with AD), and a control group (23 healthy subjects). Subjects’ serum LXB4 levels of were measured with an ELISA technique. Also, eosinophil counts and total immunoglobulin E (IgE) levels were compared among all groups. Results We observed significantly higher LXB4 levels in AD patients than in controls. Also, LXB4 levels were significantly higher in the SPT-Pos group than in the SPT-Neg group and control group. However, no significant difference was observed between the SPT-Neg and control groups. Conclusion The LXB4 may have an anti-inflammatory mediator role in the pathogenesis of AD in children. The LXB4-associated pathways may be considered in the development of novel therapeutic approaches for the treatment of patients with AD.

The Cost

Introduction. Food allergies affect 8% of the pediatric population in the United States with an estimated annual cost of US$25 billion. The low specificity of some of the main food allergy tests used in diagnosis may generate false positives incurring unnecessary costs. We examined the cost-effectiveness of oral food challenges (OFC) as confirmatory tests in the diagnosis of food allergy. Methods. We constructed a decision tree with a Markov model comparing the long-term (15 years) cost and effectiveness—in the form of quality-adjusted life years (QALY)—of confirmatory OFCs compared with immediate allergenic food elimination (FE) after a skin prick test or blood immunoglobulin E (IgE) level in children with suspected food allergy. For costs, we included the costs of OFCs and the reported annual costs of having a food allergy, including direct medical costs and costs borne by families. Results. The cost of OFC strategy was $8671 compared with $18 012 for the FE strategy for the length of the model. Also, the OFC strategy had a total QALY of 21.942 compared with 21.740 for the FE strategy. In the OFC strategy, the total cost was $9341 less than FE and the increase in QALY after OFCs led to a 0.202 higher effectiveness in the OFC strategy. Conclusion. In conclusion, our study shows that the confirmatory OFC strategy dominated the FE strategy and that a confirmatory OFC for children, within a year of diagnosis, is a cost-effective strategy that decreases costs and appears to improve quality of life.

Background The most common tests for allergen sensitization in patients with allergic rhinitis are the skin-prick test (SPT) and an in vitro test to detect serum specific immunoglobulin E (sIgE). However, in vitro allergen test results were interpreted dichotomically as positive or negative at a threshold of 0.35 kU/L of sIgE, regardless of the patient characteristics or antigen types. Objective The purpose of this study was to determine the cutoff value for sIgE in house-dust mites and animal dander, and to analyze differences in cutoff value according to age and gender. Methods A total of 16,209 patients with more than one allergic rhinitis symptom who underwent both SPT and serum sIgE testing were retrospectively evaluated between March 2008 and May 2012. There were 9374 male (57.8%) and 6835 female (42.2%) patients. The mean age was 31.8 years (range, 2–89 years). The criterion standard for allergen sensitization was defined as a wheal of >3 mm or an allergen-to-histamine ratio of ≥1 in SPT results. The Youden index was used to calculate the cutoff value of sIgE. Results Cutoff values of sIgE for Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat, and dog were 0.69, 1.16, 0.13, and 0.45 kU/L, respectively. The cutoff value of sIgE changed according to age for D. pteronyssinus and D. farinae but not for cat and dog allergens. When categorizing according to age group, the cutoffvalues ofsIgE for D. pteronyssinus and D. farinae had a tendency to decrease with age. There was no significant difference in cutoffvalue according to gender. Conclusion The cutoffvalue for sIgE differed for each antigen and changed with age. Physicians should select the proper cutoffvalue for sIgE for appropriate criteria according to antigen and patient age rather than using a uniform cutoffvalue.
