Validation of the NUT CRACKER Diagnostic Algorithm and Prediction for Cashew and Pistachio Co-Allergy.

J Allergy Clin Immunol Pract

May 2024

Institute of Allergy, Immunology and Pediatric Pulmonology, Shamir (Assaf-Harofeh) Medical Center, Zerifin, Israel; Department of Pediatrics, Faculty of Medicine, Tel-Aviv University, Tel-Aviv, Israel.

Background: Because of the high cross-sensitization among tree nuts, the NUT CRACKER (Nut Co-reactivity-Acquiring Knowledge for Elimination Recommendations) study proposed a diagnostic algorithm to minimize the number of required oral food challenges (OFCs).

Objective: To validate the algorithm for cashew and pistachio allergy and determine markers for allergic severity.

Methods: Patients (n = 125) with a median age of 7.

IRCCS Istituto Delle Scienze Neurologiche Di Bologna, Centro Regionale Per I Disturbi Della Nutrizione E Dell'Alimentazione in Età Evolutiva, U.O. Neuropsichiatria Dell'Età Pediatrica, Bologna, Italy.

Background: Recent research has documented the potential associations existing between the use of social media (SM) and the occurrence/development and treatment of Eating Disorders (ED). However, the literature directly addressing the use of SM TikTok among children and adolescents with ED is still scarce.

Methods: In January-February 2021, during the second Italian national lockdown due to the SARS-CoV-2 pandemic, an anonymous paper survey was conducted in an Italian third-level center for ED in childhood and adolescence.

Background/objectives: The European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) 2019 classification criteria for systemic lupus erythematosus system showed high specificity, while attaining also high sensitivity. We hereby analysed the performance of the individual criteria items and their contribution to the overall performance of the criteria.

Methods: We combined the EULAR/ACR derivation and validation cohorts for a total of 1197 systemic lupus erythematosus (SLE) and n=1074 non-SLE patients with a variety of conditions mimicking SLE, such as other autoimmune diseases, and calculated the sensitivity and specificity for antinuclear antibodies (ANA) and the 23 specific criteria items.

Introduction: Component-resolved diagnostics using specific IgE to 2 S albumins has shown to be a valuable new option in diagnostic procedure. Ana o 3 is a 2 S albumin from cashew. The aim of this study was to investigate the role of Ana o 3-specific serum IgE in the diagnosis of cashew allergy and to identify cut-off levels to replace oral food challenges.
