Recent Studies and Prospects of Biologics in Allergic Rhinitis Treatment.

Allergic rhinitis (AR) is a common and increasingly prevalent chronic inflammatory disorder of the nasal mucosa that severely impacts patients' quality of life, causing symptoms like nasal congestion, sneezing, and itching. AR is primarily mediated by immunoglobulin E (IgE) when allergens are present, making it challenging to manage despite available therapies like pharmacotherapy, immunotherapy, and surgery. Recently, research has focused on biologics as an emerging therapeutic option for AR. Biologics target specific immune pathways in type 2 inflammation, which underlies many allergic diseases including AR. Biologics offer a targeted and potentially more effective alternative to traditional therapies, addressing the underlying immune mechanisms rather than simply alleviating symptoms. Based on key clinical trial evidence, this paper tentatively proposes a multidimensional strategy for selecting biologics in AR, integrating serum IgE levels, disease phenotypes (seasonal/persistent), and comorbid characteristics to guide individualized treatment. However, the long-term cost-effectiveness, optimal dosing regimens, and patient adherence to biologics require further validation through real-world data. Despite these challenges, recent advancements in biologics represent a promising step forward in AR management. With ongoing research and clinical trials, biologics may soon provide more effective and lasting relief for patients suffering from allergic rhinitis.
