A Study to Evaluate the Role of Probiotics in Allergic Rhinitis

To compare treatment outcomes in allergic rhinitis patients with and without probiotics. The present study was conducted in the Out Patient Department of ENT in a Tertiary Care Hospital w.e.f. April 2023 till March 2024. Total 106 patients of allergic rhinits were included in the study and were divided randomly into 2 groups with 53 in each group. Group A was given probiotics along with standard treatment of antihistaminics and topical steroids and group B was given antihistaminics and topical steroids only. Total Nasal Symptoms Score (TNSS) of all patients was calculated at the time of enrollment and after 8 weeks post treatment. Based on the pre-treatment and post-treatment TNSS, an analysis was made whether probiotics could be an add-on therapy along with the standard treatment given for allergic rhinitis from past so many years. We conducted our study on 106 patients with mean age of 28.1 ± 8.91 years.44% were male and 56% were female. In group A pre-treatment TNSS was 8.057 + 2.307 and post treatment TNSS was 0.887 + 0.776. In group B pre-treatment TNSS was 9.45 + 0.514 and post treatment was 1.89 + 0.776. The mean post-treatment TNSS in group A was lower than the group B. This difference was statistically significant with p value of < 0.05. Based on the study we can suggest that probiotics could be a potential add-on strategy in the management of allergic rhinitis. Probiotic supplement action seems to be effective in ameliorating allergic rhinitis symptoms and improving the quality of life. However further clinical and molecular studies are required to improve our knowledge about interactions among candidate probiotics and host microbiome, cells and immune defenses, in order to create efficacious interventions.
