Abstract
The European Academy of Allergy and Clinical Immunology (EAACI) is updating the Guidelines on Food Allergy Diagnosis. We aimed to undertake a systematic review of the literature with meta-analyses to assess the accuracy of diagnostic tests for IgE-mediated food allergy. We searched three databases (Cochrane CENTRAL (Trials), MEDLINE (OVID) and Embase (OVID)) for diagnostic test accuracy studies published between 1 October 2012 and 30 June 2021 according to a previously published protocol (CRD42021259186). We independently screened abstracts, extracted data from full texts and assessed risk of bias with QUADRAS 2 tool in duplicate. Meta-analyses were undertaken for food-test combinations for which three or more studies were available. A total of 149 studies comprising 24,489 patients met the inclusion criteria and they were generally heterogeneous. 60.4% of studies were in children ≤12 years of age, 54.3% were undertaken in Europe, ≥95% were conducted in a specialized paediatric or allergy clinical setting and all included oral food challenge in at least a percentage of enrolled patients, in 21.5% double-blind placebo-controlled food challenges. Skin prick test (SPT) with fresh cow's milk and raw egg had high sensitivity (90% and 94%) for milk and cooked egg allergies. Specific IgE (sIgE) to individual components had high specificity: Ara h 2-sIgE had 92%, Cor a 14-sIgE 95%, Ana o 3-sIgE 94%, casein-sIgE 93%, ovomucoid-sIgE 92/91% for the diagnosis of peanut, hazelnut, cashew, cow's milk and raw/cooked egg allergies, respectively. The basophil activation test (BAT) was highly specific for the diagnosis of peanut (90%) and sesame (93%) allergies. In conclusion, SPT and specific IgE to extracts had high sensitivity whereas specific IgE to components and BAT had high specificity to support the diagnosis of individual food allergies.

Rev Assoc Med Bras (1992) 2016; 62:537-543. [PMID: 27849231 DOI: 10.1590/1806-9282.62.06.537] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Accepted: 07/26/2016] [Indexed: 11/22/2022] Open
Abstract
Objective: To evaluate the wheal diameter in allergy skin-prick tests (SPT) with cow's milk extract (CM) comparing tolerant and persistent patients. Method: A retrospective cohort study involving database analysis of children with diagnosis of cow's milk protein allergy (CMPA) mediated by immunoglobulin E in a specialized outpatient clinic that regularly performed SPT between January 2000 and July 2015. Patients were allocated into two groups: tolerant or persistent. Comparisons were made at diagnosis and over time between tolerant and persistent patients using Fisher's, Mann-Whitney or Wilcoxon tests and significance level at 5%. Results: After applying inclusion and exclusion criteria, the sample includes 44 patients (29 tolerant and 15 who persisted with CMPA). In the tolerant group, the medians of SPT were: 6 mm at diagnosis and 2 mm at the development of tolerance; a significant difference (p<0.0001) was found. In the persistent group, the median SPT at diagnosis was 7 mm, while in the last SPT it was 5 mm, with no statistical difference (p=0.173). The comparison of medians in the last SPT between groups was significant (p=0.001), with a reduction greater than 50% in SPT in the tolerant group. Conclusion: Serial SPTs were useful for diagnosis, and a decrease higher than 50% in diameter can indicate the moment to perform oral food challenge (OFC) tests, helping to detect tolerance in CMPA.
