Probabilistic risk assessment of anaphylactic reaction to peanut traces in peanut allergic subjects (EAACI 2025) - "Method An integrated Bayesian probabilistic risk model was developed based on the MIRABEL survey, a multicentric study involving 785 subjects with peanut allergy (PA) in France, Belgium, and Luxembourg, as well as data from 817 subjects (aged 1–17 years) enrolled in 3 pivotal studies on peanut-derived allergen immunotherapy (PDAH) (ARC003, ARC010, and ARC005)...Conclusion PDAH provides clinically meaningful protection by significantly reducing the risk of AR in both toddlers and children following API. These results demonstrate that PDAH addresses an unmet medical need that cannot be managed solely through SAA or natural PA resolution."

Satisfaction, Qol and adherence of patients allergic to dust mites and/or pollens undergoing sublingual immunotherapy. (PubMed, Immunotherapy) - "Patients were highly satisfied and most of them adhered to SLIT, being forgetfulness the main non-adherence motive. SLIT is a quick effective treatment against persistent moderate-to-severe symptoms in ARC and asthma but it should been improve forgetfulness, as non-adherence reason."

Sublingual immunotherapy for house dust mite allergy induces expansions of allergen-specific memory B cells expressing CD29 and downregulating IL4Rα (EAACI 2024) - "Lower levels of IL4Rα might render the cells less responsive to type 2 immune signals and contribute to the observed desensitization. In ongoing studies, the kinetics of immune memory changes, as well as the functional relevance of the immunophenotypical changes, are studied."

LILRA5 and CCL25 as candidate predictive biomarkers of AIT efficacy (EAACI 2024) - "Background Allergen immunotherapy (AIT) is recognised as a safe and efficacious treatment for type I respiratory allergies...When focusing on polysensitised patients with asthma, we observed an improvement in ROC analyses with area under curves reaching 0.84 and 0.7 for LILRA5 and CCL25, respectively. Conclusion Altogether, our findings clearly identify that the levels of LILRA5 and CCL25 in the blood before AIT serve as a reflection of the patient's inflammatory status, thus offering insights into the potential clinical responses expected during house dust mite immunotherapy."
