Primary prevention of food allergy in 2021: Update and proposals of French-speaking pediatric allergists.

During the past years, there has been an alarming increase in cases of food allergy and anaphylaxis in ever-younger children. Often, these children have multiple food allergies and food sensitizations, involving allergens with high anaphylactic potential, such as peanuts and nuts, which have a major influence on their quality of life and future. After reviewing the current epidemiological data, we discuss the main causes of the increase in food allergies. We analyze data from studies on the skin barrier and its fundamental role in the development of sensitization and food allergies, data on the tolerogenic digestive tract applied in particular to hen eggs and peanuts, as well as data on the prevention of allergy to cow milk proteins. In light of these studies, we propose a practical guide of recommendations focused on infants and the introduction of cow milk, the management of eczema, and early and broad dietary diversification including high-risk food allergens, such as peanut and nuts while taking into account the food consumption habits of the family.

[Latex allergy in 16 children]. / Allergie au latex chez 16 enfants.

BACKGROUND: Latex allergy is now well-known in adults and children. It represents the first cause of anaphylactic operating shock in pediatrics. POPULATION: A diagnosis of latex allergy was made in 16 children (five girls and 11 boys), aged 2 to 15 years, because of evoking signs and symptoms, from simple urticaria to Quincke edema in presence of latex. The revealing factor was wheezing in balloons in 13 out of the 16 patients. An atopic past history was frequent. Previous eventually sensitizing surgical operations were present in five patients; associated food allergy existed in four. Skin tests were positive in nine out of 12 patients, as well as latex specific IgE (13 out of 16). The diagnosis was made with a labial provocation test in one patient. CONCLUSION: Latex allergy can be severe and requires that patients avoid any contact with rubber objects, especially gloves. A detailed medical certificate should be given to the family in view of any medical, surgical or dental intervention.
