Prevalence of Self-Reported Dysphonia and Dysphagia in Patients with Allergy

Abstract

Objective: To investigate the prevalence of self-reported dysphonia and dysphagia in patients with positive allergy test in comparison to patients with negative allergy tests. Subjects and Methods: A total of 52 patients who presented to the allergy clinic of a tertiary medical referral center for skin testing between June 2019 and December 2019 were were recruited for this study. Demographic data included age, gender, history of smoking, family history for eczema, atopy, asthma, food and drug allergy. A control group of 20 subjects was matched according to age and gender. All subjects were asked to fill the voice handicap index -10 and the eating assessment tool (EAT-10) questionnaires. Results: Thirty-six of 52 patients were positive for at least one allergen, and 23 tested positive for at least three allergens. On the other hand, there was no significant difference in the mean score of VHI-10 in patients with allergy to at least one allergen, in comparison to patients with no allergy (3.667 vs 3.066, respectively, P value 0.307). Similarly, there was no significant difference in the mean score of EAT-10 between the two groups (0.305 vs 0.00, respectively, P value 0.270). There was also no significant difference in the mean score of VHI-10 in patients with allergy to at least three allergens in comparison to patients with no allergy (3.304 vs 3.066, respectively, P-value 0.603). Similarly, there was no significant difference in the mean score of EAT-10 between the two groups (0.435 vs 0.00, respectively, P-value 0.667). There was a significant difference in mean VHI-10 scores between patients testing positive for at least one allergen and the control group (P = 0.0002). Conclusion: The results of this investigation did not show any significance in the prevalence of self-reported dysphonia and dysphagia in patients with positive allergy skin testing in comparison to those with negative allergy skin-testing. More clinical studies on the prevalence of self-reported phonatory complaints in patients with allergy are warranted. © 2021
