This study is part of the Clinnova program. This is a prospective cohort study including patients with IBD recruited at the time of a treatment change.
At least 800 participants (recruited in France, Germany and Luxembourg) will be enrolled, of which 100 participants are expected to be recruited in Luxembourg with the present study protocol.
The mission of Clinnova is to support the digitalization of healthcare and precision medicine by creating a data-enabling environment for accessing, sharing and analyzing interoperable, high-quality health data.
The main hypothesis is that treatment change decided by clinicians is predictable using objective surrogate markers derived from clinical, epidemiological, and omics data. Identifying these objective markers may facilitate future treatment decisions, provide new insights on the molecular causes for differential treatment response, pathogenesis and progression, and potential pointers for improved personalized therapeutic interventions.

Peanut and tree nuts belong to the main elicitors of pediatric food allergy and are the main cause of near fatal reactions in children requiring emergency management. Oral immunotherapy has emerged as an alternative treatment option for the management of food allergies, to enhance patients' safety and quality of life. Monitoring if the therapy is working relies on oral food challenges during the course of treatment. There is a clear need for reliable biomarkers that are reflective of the clinical progression during oral food challenges and during immunotherapy that would help with patient stratification and possibly for personalized treatment approaches in the future
The aim of this study is to measure immune parameters in the blood of nut-allergic participants during oral food challenges and during the course of oral immunotherapy.
The main questions the study aims to answer are:
1. Identify immune markers that correlate with clinical reactivity
2. Identify immune changes and markers that correlate with immunotherapy outcome
Researchers will compare these immune parameters between nut-allergic participants on oral immunotherapy and with nut-allergic participants on avoidance diet. Additionally, we will also compare the immune parameters of these nut-allergic participants with those healthy adults.

This study aimed to evaluate the impact on blood glucose control and quality of life in children and youth with type 1 diabetes in Mali by switching the insulin regimen from human insulin via needle and syringe, to long-acting biosimilar insulin glargine delivered by reusable pens combined with short-acting insulin via needle and syringe.
