Tolerance development in cow's milk-allergic children receiving amino acid-based formula with synbiotics: 36-Months follow-up of a randomized controlled trial (PRESTO Study).

The objective of the present study is to assess the rates of acquired tolerance to cow's milk (CM) after 36 months in subjects who consumed amino acid-based formula with synbiotics (AAF-S) or amino acid-based formula without synbiotics (AAF) during a 1-year intervention period in early life as part of the PRESTO study (Netherlands Trial Register number NTR3725). Differences in CM tolerance development between groups were analysed using a logistic regression model. Results show that the proportion of subjects (mean [±SD] age, 3.

Phase 3 Trial of Epicutaneous Immunotherapy in Toddlers with Peanut Allergy.

Background: No approved treatment for peanut allergy exists for children younger than 4 years of age, and the efficacy and safety of epicutaneous immunotherapy with a peanut patch in toddlers with peanut allergy are unknown.

Methods: We conducted this phase 3, multicenter, double-blind, randomized, placebo-controlled trial involving children 1 to 3 years of age with peanut allergy confirmed by a double-blind, placebo-controlled food challenge. Patients who had an eliciting dose (the dose necessary to elicit an allergic reaction) of 300 mg or less of peanut protein were assigned in a 2:1 ratio to receive epicutaneous immunotherapy delivered by means of a peanut patch (intervention group) or to receive placebo administered daily for 12 months.

BSACI 2021 guideline for the management of egg allergy.

This guideline advises on the management of patients with egg allergy. Most commonly egg allergy presents in infancy, with a prevalence of approximately 2% in children and 0.1% in adults.

Food protein-induced enterocolitis syndrome in the British Isles.

Background: Food protein-induced enterocolitis syndrome (FPIES) is a delayed type of food allergy, most often seen in infancy. We aimed to estimate its incidence, to describe common food triggers and the patient journeys of this rare but serious condition.

Design: We undertook a prospective epidemiological survey of FPIES using the British Paediatric Surveillance Unit.

Tolerance development in cow's milk-allergic infants receiving amino acid-based formula: A randomized controlled trial.

Background: Tolerance development is an important clinical outcome for infants with cow's milk allergy.

Objective: This multicenter, prospective, randomized, double-blind, controlled clinical study (NTR3725) evaluated tolerance development to cow's milk (CM) and safety of an amino acid-based formula (AAF) including synbiotics (AAF-S) comprising prebiotic oligosaccharides (oligofructose, inulin) and probiotic Bifidobacterium breve M-16V in infants with confirmed IgE-mediated CM allergy.

Methods: Subjects aged ≤13 months with IgE-mediated CM allergy were randomized to receive AAF-S (n = 80) or AAF (n = 89) for 12 months.

Anaphylaxis Refractory to intramuscular adrenaline during in-hospital food challenges: A case series and proposed management.

Background: Anaphylaxis is a severe, systemic hypersensitivity reaction that can be potentially life-threatening. Anaphylaxis during oral food challenge is not uncommon and can usually be effectively managed with intramuscular adrenaline as first line treatment. Although very rare, fatal anaphylaxis during in-hospital food challenge has been reported.

Fifteen-minute consultation: The EATERS method for the diagnosis of food allergies.

The EATERS mnemonic is a novel method for taking an allergy focused clinical history. It provides a degree of certainty for diagnosing food allergy and can be used in both IgE and non IgE mediated reactions. EATERS will allow health care professionals to use their existing clinical skills to interpret the history of an allergic reaction, and by doing so will help to make sense of allergy test results.

Severity and threshold of peanut reactivity during hospital-based open oral food challenges: An international multicenter survey.

Background: Peanut allergy is classically managed by food avoidance. Immunotherapy programs are available at some academic centers for selected patients reacting to small amounts of peanut during food challenge. We aimed to determine and compare reaction thresholds and prevalence of anaphylaxis during peanut oral challenges at multiple specialist allergy centers.

Prevalence and longitudinal trends of food allergy during childhood and adolescence: Results of the Isle of Wight Birth Cohort study.

Background: The prevalence and time trends of food allergy change during childhood depending on the age of the child and the type of food.

Objective: To study prevalence and longitudinal trends in food allergy from birth to 18 years in an unselected birth cohort in the Isle of Wight.

Method: Information on food allergy was collected at ages 1, 2, 4, 10 and 18 years from the Isle of Wight Birth Cohort (n = 1456).

In vitro rapid diagnostic tests for severe drug hypersensitivity reactions in children.

Background: Previous reports have demonstrated the utility of T-cell proliferation and cytokine release assays as in vitro diagnostic tests for drug causation in drug hypersensitivity reactions (DHR). However, data from pediatric populations are scarce compared with data in adults.

Objective: To compare the lymphocyte proliferation assay (LPA) with combination cytokine assays in the pediatric population and to identify its potential use in the acute and postrecovery phases.

Safety of live attenuated influenza vaccine in young people with egg allergy: multicentre prospective cohort study.

Study Question: How safe is live attenuated influenza vaccine (LAIV), which contains egg protein, in young people with egg allergy?

Methods: In this open label, phase IV intervention study, 779 young people (2-18 years) with egg allergy were recruited from 30 UK allergy centres and immunised with LAIV. The cohort included 270 (34.7%) young people with previous anaphylaxis to egg, of whom 157 (20.

Safety of live attenuated influenza vaccine in atopic children with egg allergy.

Background: Live attenuated influenza vaccine (LAIV) is an intranasal vaccine recently incorporated into the United Kingdom immunization schedule. However, it contains egg protein and, in the absence of safety data, is contraindicated in patients with egg allergy. Furthermore, North American guidelines recommend against its use in asthmatic children.
