The Role of Nut Sensitization in Pru p 3-Sensitized Patients: A XGBoost and Generalized Linear Model Application
This study leverages AI to analyze nut sensitization patterns in Pru p 3-sensitized patients, identifying key predictors of clinical reactivity and severity. XGBoost and GLM models highlight walnut sensitization as the strongest predictor of severe reactions, with increasing sensitizations correlating with higher severity. These insights enable refined risk stratification and personalized management for nsLTP-related food allergies.

AI in Allergology
Artificial intelligence (AI) algorithms, particularly XGBoost, are revolutionizing medical diagnostics and epidemiology by managing complex, high-dimensional data with non-linear relationships. In allergology, AI supports early diagnosis, epidemic prediction, and personalized analysis, learning hidden patterns from empirical data. XGBoost's strengths include gradient boosting for non-linear relationships, scalability, and computational optimizations like regularization and parallelization. This enables more effective risk stratification and management compared to traditional statistical models.
nsLTPs & Cross-Reactivity
Non-specific lipid transfer proteins (nsLTPs) are a widespread family of plant proteins, highly prevalent in Mediterranean countries. Pru p 3 from peach is a major nsLTP allergen, responsible for IgE-mediated food allergies and extensive cross-reactivity due to high sequence homology with nsLTPs from other Rosaceae fruits and botanically unrelated sources like nuts and pollens. This cross-reactivity complicates diagnosis, leading to the concept of LTP syndrome, where allergic symptoms can manifest to multiple phylogenetically unrelated nsLTPs. Co-factors like NSAID intake or exercise can exacerbate reactions.
Nut Sensitization Patterns
In Pru p 3-sensitized patients, sensitization patterns to nuts vary. Peanut and hazelnut sensitization are most frequent, but AI analysis reveals stronger associations between clinical reactivity and sensitization to hazelnut, walnut, and almond. Walnut sensitization emerges as the strongest predictor of clinical severity, and an increasing number of sensitizations correlates with higher severity. This highlights the importance of specific nut allergens, like walnut, as molecular markers for identifying patients at higher risk of systemic reactions, expanding on the traditionally dominant role of Pru p 3.
