Filter by:The objectives of the CAJESITO study are (i) to assess the tolerance of oral cashew nut immunotherapy, by describing the frequency and severity of allergic reactions during oral cashew nut immunotherapy and (ii )to assess the risk factors for severe allergic reactions during oral cashew nut immunotherapy (predictive factors, associated factors.
The LMNOP trial will be a 2-armed, open-label, randomised controlled trial (RCT), 2:1. Over a period of 18 months, children in the Multi-Nut Oral Immunotherapy Treatment (OIT) Group (experimental arm) will undergo low dose OIT to two nuts they are allergic to. At this time, children in the Standard Care Group (control arm) will be instructed to strictly avoid consuming two nuts they are allergic to. Avoiding consuming nut allergens is the standard care advice for children with peanut/tree nut allergies in Australia. The trial will assess the difference in the proportion of participants undergoing Multi-Nut OIT who can achieve sustained unresponsiveness (SU) compared to the proportion of participants avoiding nuts who develop natural tolerance (NT), i.e. grow out of their allergy. SU is when a participant can pass an oral food challenge (OFC) after having paused OIT treatment for several weeks. Participants will be between the ages of 18 and 36 months at the time of screening. The first 12 participants enrolled will be part of the pilot phase, with a total of n = 45 for the main trial. It is hypothesised that there will be a higher proportion of participants in the Multi-Nut OIT Group versus the Standard Care Group who pass the OFC following the 18-month treatment phase. That is, a higher proportion of participants in the Multi-Nut OIT Group will achieve SU compared to participants in the Standard Care Group achieving NT.
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.
