Abstract
I. EXECUTIVE SUMMARY BACKGROUND: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR-RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR-RS-2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence-based findings of the document. METHODS ICAR-RS presents over 180 topics in the forms of evidence-based reviews with recommendations (EBRRs), evidence-based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. RESULTS ICAR-RS-2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence-based management algorithm is provided. CONCLUSION This ICAR-RS-2021 executive summary provides a compilation of the evidence-based recommendations for medical and surgical treatment of the most common forms of RS.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a multifactorial inflammatory disease. Particularly, eosinophilic CRS is often recalcitrant to treatment, so an appropriate animal model is required to evaluate the pathogenesis of, and to develop therapies for, recalcitrant eosinophilic CRS. This study aimed to improve the ovalbumin (OVA)-induced mouse model of eosinophilic/allergic CRS by combining OVA with Aspergillus protease, which is known to trigger allergic reactions in mouse lungs. METHODS In a model of allergic CRS, mice were challenged intranasally with Aspergillus protease combined with OVA. Local and systemic responses were measured. Protease (0.54 U) from Aspergillus oryzae, prepared with or without OVA (75 micrograms), OVA alone, or saline, was administered intranasally to wild-type mice for 5 weeks. Sinonasal complex samples were evaluated histologically, and interleukin (IL)-4, IL-5, IL-6, macrophage inflammatory protein (MIP) 2, and tumor necrosis factor (TNF) alpha were measured in nasal lavage fluid. A differential white blood cell count was also performed. RESULTS OVA alone induced minimal eosinophilic inflammation in sinonasal mucosa, while protease + OVA and protease alone induced moderate eosinophilic inflammation. Protease + OVA elevated eosinophil counts in blood comparable with controls, but not compared with OVA alone. Although IL-4, IL-5, IL-6, MIP-2, and TNF-alpha were increased in all study mice, the levels of IL-4 and IL-6 were higher in mice treated with protease + OVA than in mice treated with OVA alone. Protease alone excessively elevated the levels of IL-6, MIP-2, and TNF-alpha, not Th2 cytokines, compared with OVA alone and protease + OVA. CONCLUSION Aspergillus protease combined with OVA induced more severe allergic inflammation in sinonasal mucosa compared with OVA alone and similar eosinophilia. This model could be more relevant to recalcitrant eosinophilic CRS in humans than OVA-induced allergic CRS.

Abstract
Fungi in paranasal sinuses are characteristic and considered a major pathogenic factor in a subset of chronic rhinosinusitis (CRS) patients, known as allergic fungal rhinosinusitis (AFRS). CD8+ T cells are enriched in AFRS sinuses but their role in fungal-specific responses is unknown. Alternaria alternata– and Aspergillus fumigatus–specific T lymphocyte responses were investigated in 6 AFRS patients, 10 eosinophilic mucus CRS (EMCRS) patients, 10 CRS with nasal polyps (CRSwNPs) patients, 6 allergic rhinitis with fungal allergy (ARFA) patients, and five controls. Fungal-specific proliferation of human peripheral blood mononuclear cells (PBMCs) was studied prospectively. Proliferating cells were examined for CD3, CD4, CD8, and CD25 expression. Relevant clinical characteristics, fungal allergy, detection of fungi in sinuses, and CD4+ and CD8+ composition of sinus T cells were also examined. CD4+ T-cell division to fungi occurred in all samples, regardless of fungal allergy or CRS. Fungal-specific CD8+ T-cell division occurred in all ARFA and control samples and the majority of CRSwNP patients; however, CD8+ T cells failed to proliferate in AFRS and EMCRS patients. The CD8+ T cells from AFRS patients also did not up-regulate the activation marker, CD25, with fungal antigen exposure. Presence of A. alternata– and A. fumigatus–specific CD4+ and CD8+ T-cell proliferation in healthy individuals, ARFA, and CRSwNP patients suggests that both T-cell subsets may be important in immune responses to these fungi. In AFRS and EMCRS patients, only fungal-specific CD4+ T-cell proliferation occurred; hence, a lack of CD8+ T-cell proliferation and activation in the presence of sinus eosinophilic mucus in these patients, regardless of fungal allergy, is a novel finding. This raises the question whether a dysfunctional CD8+ T-cell response predisposes to ineffective clearance and accumulation of fungi in the sinuses of susceptible patients.
