Abstract

Background: Chronic rhinosinusitis with nasal polyps (CRSwNPs) involves persistent sinus inflammation, with emerging evidence suggesting a potential role of rhinovirus (RV) in its pathophysiology. However, whether RV exists in nasal tissues and affects the nasal mucosa after the resolution of infection symptoms remains unknown.

Objective: To investigate the prevalence and impact of silent RV infection in nasal tissues.

Methods: RV loads were detected in the nasal tissues of 47 controls and 101 patients with CRSwNP without respiratory infection. Participants were categorized into RV-positive (+), RV-negative (-), and the "gray zone" groups. Quantitative polymerase chain reaction, Western blotting, and immunofluorescence assays were used to analyze the impact of silent RV infection on the immune status of nasal tissues.

Results: Silent RV infection was prevalent in both control (34%) and CRSwNP (30.7%) tissues, with higher viral loads observed in the nasal polyps. In controls, it was associated with high expression of types 1 and 2 interferon (IFN), type 2 inflammation, interleukin (IL)-17A, and IL-10. In patients with CRSwNP, silent RV infection was associated with lower levels of type 1 IFN, IL-17A, type 2 inflammation, and IL-10 but higher levels of type 2 IFN compared with those without RV infection. Meanwhile, RV (+) nasal polyps exhibited fewer tissue eosinophils and neutrophils than RV (-) nasal polyps.

Conclusion: Silent RV infection was prevalent in the nasal tissues, with a higher viral load detected in the nasal polyps. This silent RV infection is associated with distinct immune responses in healthy controls and patients with CRSwNP, involving differential modulation of IFNs, T_H2 cytokines, IL-17A, IL-10, and eosinophil and neutrophil levels.

期刊介绍： Annals of Allergy, Asthma & Immunology is a scholarly medical journal published monthly by the American College of Allergy, Asthma & Immunology. The purpose of Annals is to serve as an objective evidence-based forum for the allergy/immunology specialist to keep up to date on current clinical science (both research and practice-based) in the fields of allergy, asthma, and immunology. The emphasis of the journal will be to provide clinical and research information that is readily applicable to both the clinician and the researcher. Each issue of the Annals shall also provide opportunities to participate in accredited continuing medical education activities to enhance overall clinical proficiency.
