Accuracy of Nasal House Dust Mite-Specific Immunoglobulin E in Diagnosis of Local Allergic Rhinitis

Background: Local allergic rhinitis (LAR) is the symptom of allergic rhinitis in which nasal allergen-specific immunoglobulin E(IgE) is detected but has no sensitivity to systemic allergens. The gold standard test is the nasal allergen provocation test (NAPT) which requires a complicated procedure. Specific IgE in nasal mucosa test is the less invasive and easier diagnostic alternative for LAR. Aims: This review aimed to determine the validity of the nasal house dust mite-specific IgE test for LAR patients. Study designs: A meta-analysis was conducted in chronic rhinitis patients with negative skin prick test (SPT) and serum IgE. Methods: The research was using PubMed Central, Cochrane library, SAGE journals, and Science Direct were searched until July 29th, 2022. The validity of the nasal HDM-specific IgE test was compared to NAPT. Results: A total of 413 research articles were selected and five articles were included. The QUADAS-2 assessment showed minimum publication bias. The total sample was 236 patients. Pooled sensitivity 90.00%, I2= 28.95% and p=0.01. Pooled specificity 96.00%, I2= 30.28% and p=0.00. The value of the area under the curve in the SROC curve = 0.9710, statistically significant. Conclusion: The nasal HDM-specific IgE test is valid for diagnosing patients with LAR.
