No approved treatment for peanut allergy exists children younger than 4 years of age, and the efficacy safety epicutaneous immunotherapy with a patch in toddlers are unknown. We conducted this phase 3, multicenter, double-blind, randomized, placebo-controlled trial involving 1 to 3 age confirmed by food challenge. Patients who had an eliciting dose (the necessary elicit allergic reaction) 300 mg or less protein were assigned 2:1 ratio receive delivered means (intervention group) placebo...

Abstract Adolescent and young adult (AYA) patients need additional support, while they experience the challenges associated with their age. They specific training to learn knowledge skills required confidently self‐manage allergies and/or asthma. Transitional care is a complex process, which should address psychological, medical, educational vocational needs of AYA in developmentally appropriate way. The European Academy Allergy Clinical Immunology has developed clinical practice guideline...

Abstract Genetic factors and mechanisms underlying food allergy are largely unknown. Due to heterogeneity of symptoms a reliable diagnosis is often difficult make. Here, we report genome-wide association study on diagnosed by oral challenge in 497 cases 2387 controls. We identify five loci at significance, the clade B serpin (SERPINB) gene cluster 18q21.3, cytokine 5q31.1, filaggrin gene, C11orf30/LRRC32 locus, human leukocyte antigen (HLA) region. Stratifying results for causative...

Abstract Background The benefit of daily administration Peanut ( Arachis hypogaea ) Allergen Powder‐dnfp (PTAH)—formerly AR101—has been established in clinical trials, but limited data past the first year treatment are available. This longitudinal analysis aimed to explore impact continued PTAH therapeutic maintenance dosing (300 mg/day) on efficacy, safety/tolerability, and food allergy‐related quality life. Methods We present a subset PALISADE‐ARC004 participants (aged 4–17 years) who...
