Symptomatology and Management of Adult Anaphylaxis according to Trigger: A Cross-Sectional Study.

Introduction: Anaphylaxis is an acute life-threatening allergy, most commonly provoked by food, venom, or drugs. There is limited data regarding differences in symptomatology between anaphylaxis provoked by different triggers. This study aimed to assess sociodemographic characteristics, clinical symptoms, and management of anaphylaxis, according to triggers in adults.

Management of anaphylaxis after pre-hospital epinephrine use in children with food-induced anaphylaxis.

Background: Previous guidelines recommend prompt epinephrine administration, followed by observation in the emergency department (ED). The need for transfer in all cases of anaphylaxis has recently been challenged.

Objective: To evaluate the need for additional ED treatment among children with anaphylaxis who received prehospital epinephrine.

Clinical characteristics and management of pediatric egg-induced anaphylaxis: A cross-sectional study.

Background: Egg is the third most common food allergy in children; however, data on pediatric egg-induced anaphylaxis are sparse.

Objective: To describe the clinical characteristics, management, and outcomes of pediatric egg-induced anaphylaxis.

Methods: Children presenting with anaphylaxis were recruited from 13 emergency departments as part of the Cross-Canada Anaphylaxis Registry, from which data on anaphylaxis triggered by egg were extracted.

Milk-induced anaphylaxis among children presenting to Canadian emergency departments.

Background: Cow's milk is one of the most common and burdensome allergens in pediatrics, and it can induce severe anaphylactic reactions in children. However, data on cow's milk-induced anaphylaxis are sparse.

Objective: To describe the epidemiology of pediatric cow's milk-induced anaphylaxis and to determine risk factors for repeat emergency department (ED) epinephrine administration.

Temporal trends in anaphylaxis ED visits over the last decade and the effect of COVID-19 pandemic on these trends.

Background: Anaphylaxis is an acute systemic and potentially fatal allergic reaction. We evaluated trends in yearly rates of anaphylaxis in a pediatric Emergency Department (ED) in Montreal, Canada.

Methods: A prospective and retrospective recruitment process was used to find families of children who had presented with anaphylaxis at the Montreal Children's Hospital between April 2011 and April 2021.

Sesame-induced anaphylaxis in pediatric patients from the cross-Canada anaphylaxis registry.

Background: Sesame can cause severe allergic reactions and is a priority allergen in Canada.

Objective: To assess clinical characteristics and management of pediatric sesame-induced anaphylaxis and identify factors associated with epinephrine treatment.

Methods: Between 2011 and 2021, children with sesame-induced anaphylaxis presenting to 7 emergency departments (ED) in 4 Canadian provinces and 1 regional emergency medical service were enrolled in the Cross-Canada Anaphylaxis Registry.

Seafood-induced anaphylaxis in children presenting to Canadian emergency departments: Rates, clinical presentation, and management.

Background: There is a lack of data on seafood-induced anaphylaxis in children in Canada.

Objective: To evaluate the rate, clinical features, and management of seafood-induced anaphylaxis in children presenting to emergency departments across Canada.

Methods: Children with anaphylaxis were recruited at 6 emergency departments between 2011 and 2020 as part of the Cross-Canada Anaphylaxis REgistry.

Fruit-Induced Anaphylaxis: Clinical Presentation and Management.

Background: Data are sparse regarding the clinical characteristics and management of fruit-induced anaphylaxis.

Objective: To assess clinical characteristics and management of patients with fruit-induced anaphylaxis and determine factors associated with severe reactions and epinephrine use.

Methods: Over 9 years, children and adults presenting with anaphylaxis to seven emergency departments in four Canadian provinces and patients requiring emergency medical services in Outaouais, Quebec were recruited as part of the Cross-Canada Anaphylaxis Registry.

Short- and long-term management of cases of venom-induced anaphylaxis is suboptimal.

Background: Venom-induced anaphylaxis (VIA) accounts for severe reactions. However, little is known about the short- and long-term management of VIA patients.

Objective: To assess the short- and long-term management of VIA.

Anaphylaxis cases presenting to primary care paramedics in Quebec.

Data on anaphylaxis cases in pre-hospital settings is limited. As part of the Cross Canada Anaphylaxis Registry (C-CARE), we assessed anaphylaxis cases managed by paramedics in Outaouais, Quebec. A software program was developed to prospectively record demographic and clinical characteristics as well as management of cases meeting the definition of the anaphylaxis.
