The Relationship

A few chronic rhinosinusitis (CRS) variants have demonstrated a strong association with environmental allergy, including allergic fungal rhinosinusitis (AFRS) and central compartment atopic disease (CCAD). However, the overall relationship between CRS and allergy remains poorly defined. The goal of this review is to evaluate the relationship between CRS and allergy with a focus on specific CRS variants.

The Relationship

The European Position Paper on Rhinosinusitis and Nasal Polyps 2012 is the update of similar evidence based position papers published in 2005 and 2007. The document contains chapters on definitions and classification, we now also proposed definitions for difficult to treat rhinosinusitis, control of disease and better definitions for rhinosinusitis in children. More emphasis is placed on the diagnosis and treatment of acute rhinosinusitis. Throughout the document the terms chronic rhinosinusitis without nasal polyps (CRSsNP) and chronic rhinosinusitis with nasal polyps (CRSwNP) are used to further point out differences in pathophysiology and treatment of these two entities. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. Last but not least all available evidence for management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is analyzed and presented and management schemes based on the evidence are proposed. This executive summary for otorhinolaryngologists focuses on the most important changes and issues for otorhinolaryngologists.

Objective Allergic fungal rhinosinusitis (AFRS) is a clinical subtype of chronic rhinosinusitis with nasal polyps (CRSwNP), characterized by eosinophilic mucin, evidence of fungal elements within the mucin, fungal-specific type I hypersensitivity, and characteristic computed tomography findings. It remains controversial whether AFRS represents a disease with a unique pathophysiology from chronic rhinosinusitis or is merely a severe form of CRSwNP. The goal of this study was to identify molecular features unique to AFRS. Study Design Cross-sectional case-control. Setting Single academic tertiary referral institution. Subjects and Methods Subjects included 86 patients undergoing endoscopic sinus surgery: CRSwNP (n = 34), AFRS (n = 37), and healthy controls (n = 15). Pathway and correlation analyses were performed with whole-genome microarray data for study patients undergoing surgery for recalcitrant chronic rhinosinusitis. Our findings were confirmed with quantitative polymerase chain reaction and immunohistochemical studies. Results AFRS was uniquely characterized by a pronounced association with adaptive T helper 2–associated immune gene expression. AFRS exhibited altered expression of proteins associated with secretory salivary peptides—namely, histatin, a peptide with known antifungal activity in the oral cavity. Furthermore, the expression of histatins correlated negatively with that of type 2 inflammatory mediators. We confirm the decreased expression of histatins in AFRS when compared with CRSwNP by quantitative polymerase chain reaction and localized its expression to a submucosal cell population. Conclusion There exist clear molecular profiles that distinguish AFRS from CRSwNP. This divergence translates into an altered ability to control fungal growth and may in part explain some of the phenotypical differences between CRSwNP and AFRS.

Allergic Fungal Rhinosinusitis

Background. Allergic fungal rhinosinusitis is a noninvasive form of highly recurrent chronic rhinosinusitis. Despite the advancement in medical and surgical strategies, recurrence in AFRS in general poses another challenging problem with reported incidence that eventually can reach more than 60%. Recognition and understanding the pattern of disease recurrence will lead to greater understanding of the disease response in our population. Method. A retrospective cohort study was performed in King Abdulaziz Medical City in Riyadh, Saudi Arabia. All patients diagnosed with chronic rhinosinusitis and underwent functional endoscopic sinus surgery from the period of January 2006 to December 2016 were reviewed. Results. 28 patients were found to have AFRS based on clinical, radiological, and microscopic examination suggestive of allergic fungal rhinosinusitis. Among these patients, 53% of them were female and 46% were male. The age ranged from 13 to 55 years, with a mean age of 31.57 years. 28.57% of the patients presented with recurrent allergic fungal sinusitis. The duration between the surgery and symptoms recurrence was around one year. Male and female patients had similar recurrence rate (50%). At first visit, 95% of the patients with nonrecurrent disease presented with nasal obstruction compared to 87.5% of the patients with recurrent disease. On the other hand, patients with recurrent disease had more nasal discharge (87.5%), postnasal drip (37.5%), facial pressure/pain (50%), headache (50%), nasal polyposis (87.5%), hypertrophy of inferior turbinate (37.5%), and proptosis (12.5%). Nasal obstruction (87.5%) and nasal polyps (87.5%) were the most common presenting symptoms for the disease recurrence. The pattern of disease recurrence in the previously unilateral disease was 18% ipsilateral and 27% bilateral. For the patients who had bilateral disease formerly, 17% (n = 3) of them had recurrent bilateral disease. Conclusion. Allergic fungal rhinosinusitis is a distinct clinical entity. A high recurrence rate is a pathognomonic feature of the disease, despite all the development in medical and surgical trials. This study demonstrated that recurrence rate is lower in our population. However, more studies with a greater number of patients are needed in the future to clearly recognize the pattern of recurrence in patients with AFRS.

Background Ever since its characterization in the 1970s, allergic fungal rhinosinusitis (AFRS) has been the subject of much controversy, especially regarding its pathogenesis. In this study, we analyzed the differential expression of genes that encode protease-activated receptors (PAR) in patients with AFRS and patients with chronic rhinosinusitis, and tried to understand the pathogenic basis of this disease. Objective To analyze the differential expression of PAR genes in patients with AFRS and in patients with chronic rhinosinusitis. Methods Mucosa from ethmoid sinuses of 51 patients (tests and controls) was biopsied and evaluated for messenger RNA expression of PAR genes by using reverse transcriptase–polymerase chain reaction. Each of the four PAR genes, i.e., par1, par2, par3 and par4 was amplified, the final gene products were run on 1.8% agarose gel and analyzed by densitometry to calculate differential expression. The significance level was determined as p ≤ 0.05. Results It was observed that the expressions of all four par genes were higher in the test samples compared with the controls, but statistical significance was achieved only for par1 (p=0.004) and par2 (p=0.05). Comparative expression of the four PAR genes was also performed within the test and control groups, and a statistically significant difference was seen between par1 and par2 (p=0.007), par1 and par3 (p=0.029), par1 and par4 (p=0.0001), par2 and par4 (p=0.002), and par3 and par4 (p=0.009) in the test group. In the control group as well, par1, par2, and par3 exhibited a higher expression compared with par4 but the difference was significant between par3 and par4 genes only. Conclusion Patients with AFRS expressed increased levels of PAR genes in their nasal mucosa, and, of the four PAR genes, a higher expression of par1, par2, and par3 was observed in both the groups compared with par4. This information contributes toward our understanding of pathogenesis and possibly treatment of AFRS.

Background Respiratory epithelial adenomatoid hamartoma (REAH) is a benign lesion of the sinonasal tract that may mimic more concerning pathology. Clinical factors associated with REAH have not been well characterized. Objective To report our findings on patients with this pathologic diagnosis. Methods A retrospective chart review of patients with REAH between September 2006 and November 2019 was conducted. Data collected included clinical allergic rhinitis and asthma history, additional sinonasal diagnoses, prior sinus surgery, and the location of the REAH within the sinonasal cavity. Results Twenty-six patients were identified (53.8% male, mean age 62 years [range, 29–93]). Bilateral REAH occurred in 50%. REAH was located at the superior nasal septum in 84.6% cases, with the remainder identified in sinus contents submitted for pathology, making definitive site uncertain. Concurrent sinonasal inflammatory disorders were identified in 18 patients (69.2%), including chronic rhinosinusitis with nasal polyps—not otherwise specified (6), chronic rhinosinusitis without nasal polyps (4), aspirin-exacerbated respiratory disease (2), allergic fungal rhinosinusitis (1), central compartment atopic disease (5), and IgG4-related sclerosing disease (1). Eight patients had isolated REAH. Adequate allergy records were available for 19 patients, of which 18 of 19 (94.7%) had clinical allergic rhinitis. Conclusions REAH is a benign sinonasal lesion commonly located within the central compartment of the nasal cavity, a site of significant allergen exposure. Affected patients have a high incidence of allergy along with chronic inflammatory conditions. The coexistence of REAH within inflammatory nasal mucosa in a consistent anatomic location, suggests REAH may have a similar etiology to central compartment atopic disease, with resultant respiratory glandular ingrowth within long-standing reactive changes of mucosa derived from ethmoid embryologic origin.
