The pilot study of type Ⅰ allergic reaction in Meniere′s disease patients / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

Objective@#To evaluate the correlation between type Ⅰ allergic reaction and pathogenesis of Meniere′s disease.@*Methods@#A total of 35 (10 male vs. 25 female) patients aged between 21-66 years diagnosed with Meniere′s disease were recruited to this study, mean age of them was (47.3±13.6) years. The control group consisted of 15 inpatients (5 male vs. 10 female) with pharyngolaryngeal diseases but without otologic and rhinologic abnormity, mean age was 45.4±12.8 years. Allergic prevalence, serous total immunoglobulin E( tIgE ) levels, serous specific immunoglobulin E( sIgE ) levels and subtypes of T lymphocytes were measured and compared in patients with Meniere′s disease and the control group. Severity of vertigo, tinnitus and sensation of fullness were compared between Meniere′s disease patients with or without allergy.@*Results@#Allergic prevalence were significantly different (Pearson chi-square 5.832, P<0.05) between patients with Meniere′s disease and the control group(57.1% vs. 20.0%). Patients with Meniere′s disease report higher level of serous tIgE compared with controls, the difference is statistically significant (Z=168.000, P<0.05). However, positive rates of sIgE of food allergens and inhalant allergens were not significantly different between patients with Meniere′s disease and the control group. Scores of vertiginous severity, dizziness handicap inventory (DHI) and tinnitus handicap inventory (THI) were significantly different between Meniere′s disease patients with or without allergy (P<0.05). Treg and Treg/Th17 levels (Z=26.000) were much higher in Meniere′s disease patients with allergy than in the controls(P<0.05).@*Conclusions@#Patients with Meniere′s disease report higher rate of allergy than the control group. Type Ⅰ allergic reaction is thought to be one of the possible reasons that may induce endolymphatic hydrops and lead to Meniere′s disease.
