Efficiency And Tolerance Of Hazelnut Oral Immunotherapy Protocol In Hazelnut Allergic Children

Study Purpose

Prevalence of food allergy in the world has been inscreasing in recent years. Among nut allergy, hazelnut allergy is the most widespread in Europe and particularly in France. The current treatment for hazelnut allergy is based on eviction and wearing of an emergency kit with adrenaline auto-injector pens, to be used in the event of severe anaphylactic reaction. Oral immunotherapy (OIT) is a treatment that is now increasingly being offered as an alternatice to eviction. There are few published data concerning hazelnut OIT in Europe, where its consumption is nevertheless very high. The main objective of our study is to evaluate the clinical efficacy of the hazelnut OIT protocol, implemented since 2015 in the pneumology and allergology-paediatric department of the Mother and Child Hospital in Bron, in hazelnut allergic children under 18 years old. The secondary objectives will be to evaluate the biological efficacy and clinical tolerance of the protocol. The study is retrospective and observational, and is based on the collection of medical data from patient records.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
