“…Although the role of local IgE production plays against SEs and mites in the pathogenesis of CRSwNP has been described [7,8,9,10], our findings indicate that fungi are also important allergens that cause eosinophilic inflammation, not only in AFRS but also in CRSwNP. Fungi are environmentally ubiquitous and, except when invasive, are generally not looked upon as being harmful/pathological.…”

Background: Total and specific immunoglobulin E (IgE) in nasal polyps (NP) is related to local eosinophilic inflammation. However, it remains unclear which antigens cause a stronger accumulation of eosinophils in NP. We investigated whether local IgEs to specific antigens correlated with local eosinophil accumulation. Methods: Total IgE, antigen-specific IgEs [5 species of fungi, staphylococcal enterotoxins A and B (SEA and SEB), cedar pollen, ragweed pollen and house-dust mites] and eosinophil cationic protein (ECP) were measured in sinus mucosa homogenates and serum from 29 patients with chronic rhinosinusitis with NP (CRSwNP), 8 patients with allergic fungal rhinosinusitis (AFRS) and 8 control subjects without CRS. The level of ECP in NP was analyzed for correlations with the total and specific IgE levels in the serum and NP. Results: In CRSwNP, antigen-specific IgEs [Alternaria > mite (Dp) > Aspergillus > SEB > Penicillium > mite (Df), but not the other fungi, SEA or pollens] in the sinus mucosa correlated significantly with the local ECP.In AFRS, antigen-specific IgEs [Penicillium > mite (Df) > Alternaria, but not the other fungi, SEs or pollens] in the sinus mucosa correlated significantly with the local ECP. Conclusions: Local total IgE and antigen (fungi, mites and SEs)-specific IgEs in NP are related to the local eosinophilic inflammation of AFRS and CRSwNP.

“…Local IgE-positive cells in AFRS are increased [9]. Not only antifungal, also antinonfungal IgE, was expressed in sinus tissues of AFRS, compared to the control [10]. Local total IgE correlated significantly with local IL-5, eosinophil cationic protein (ECP) and with the number of eosinophils in NP [7].…”

“…1086 Various studies demonstrate elevation of fungal and nonfungal IgE within AFRS mucosa, and local IgE correlates with sinonasal eosinophilia. 917,1079,1080,1093,1099,1100 Most AFRS patients also have detectable fungal-specific IgE in their mucin. 1077 AFRS is a distinct, often more severe, subclass of CRSwNP.…”

Background:The body of knowledge regarding rhinosinusitis (RS) continues to expand, with rapid growth in number of publications, yet substantial variability in the quality of those presentations. In an effort to both consolidate and critically appraise this information, rhinologic experts from around the world have produced the International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR:RS). Methods:Evidence-based reviews with recommendations (EBRRs) were developed for scores of topics, using previously reported methodology. Where existing evidence was insufficient for an EBRR, an evidence-based review (EBR) was produced. The sections were then synthesized and the entire manuscript was then reviewed by all authors for consensus. Results:The resulting ICAR:RS document addresses multiple topics in RS, including acute RS (ARS), chronic RS (CRS) with and without nasal polyps (CRSwNP and CRSsNP), recurrent acute RS (RARS), acute exacerbation of CRS (AE-CRS), and pediatric RS. Conclusion:As a critical review of the RS literature, ICAR:RS provides a thorough review of pathophysiology and evidence-based recommendations for medical and surgical treatment. It also demonstrates the significant gaps in our understanding of the pathophysiology and optimal management of RS. Too o en the foundation upon which these recommendations are based is comprised of lowerlevel evidence. It is our hope that this summary of the evidence in RS will point out where additional research efforts may be directed. C 2016 ARS-AAOA, LLC.

“…Specific IgE to both fungal and nonfungal antigens were also demonstrated in higher concentrations from patients with AFRS as opposed to controls. 45 A follow-up study by Ahn and colleagues 46 in 2009 affirmed previous findings of elevated levels of total and specific IgE in sinonasal tissue obtained from patients with AFRS relative to those with CRS and healthy controls. This group also demonstrated that elevated local tissue IgE appears to be a diffuse process throughout nose and paranasal sinuses, with similar amounts of IgE detectable in tissue from the paranasal sinuses as the inferior turbinate samples, despite the predisposition for polyps to form in the sinus cavity rather than on the inferior turbinates ( Figs.…”
