Practical protocol of the food allergy committee of the seicap on open oral food challenges to nuts.

Food allergy is rising rapidly among children, and allergy to nuts is one of the most prevalent allergies among them. The category "nuts and seeds" include several plant foods from different botanical families, very different from each other. It is not uncommon to detect co-sensitization to different nuts.

Treatment with proton pump inhibitors as a cofactor in adverse reactions of patients undergoing oral food immunotherapy.

Background And Objectives: Based on previous studies revealing acid-suppression medication as a risk factor for food allergy tolerance induction, we aimed to establish the importance of those findings in patients undergoing oral immunotherapy (OIT).

Materials And Methods, Results: We describe a case series of four patients who underwent milk OIT with a concomitant use of proton pump inhibitor (PPI) medication and who developed anaphylaxis after a known, previously tolerated dose of milk.

Conclusions: PPIs may act as a cofactor in patients undergoing OIT, triggering adverse reactions, irrespective of the PPI used or the dosage.

Consensus document on the approach to children with allergic reactions after vaccination or allergy to vaccine components.

Vaccinations are one of the main public health tools for the control of vaccine-preventable diseases. If a child is identified as having had an allergic reaction to a vaccine, subsequent immunisations will probably be suspended - with the risks such a decision implies. The incidence of severe allergic reactions is very low, ranging between 0.
