Abstract
The management of asthma has fundamentally changed during the past decades. The present guideline for the diagnosis and treatment of asthma was developed for respiratory specialists who need detailed and evidence-based information on the new diagnostic and therapeutic options in asthma. The guideline shows the new role of biomarkers, especially blood eosinophils and fractional exhaled NO (FeNO), in diagnostic algorithms of asthma. Of note, this guideline is the first worldwide to announce symptom prevention and asthma remission as the ultimate goals of asthma treatment, which can be achieved by using individually tailored, disease-modifying anti-asthmatic drugs such as inhaled steroids, allergen immunotherapy or biologics. In addition, the central role of the treatment of comorbidities is emphasized. Finally, the document addresses several challenges in asthma management, including asthma treatment during pregnancy, treatment of severe asthma or the diagnosis and treatment of work-related asthma.

Abstract
Unified airway disease, including concurrent asthma and chronic rhinosinusitis (CRS), is a common, but poorly understood disorder with no curative treatment options. To establish a murine model of chronic unified eosinophilic airway inflammation, mice were challenged with Aspergillus niger, and sinonasal mucosa and lung tissue were evaluated by immunohistochemistry, flow cytometry, and gene expression. Inhalation of A niger conidia resulted in a Th2-biased lung and sinus inflammation that typifies allergic asthma and CRS. Gene network and pathway analysis correlated with human disease with upregulation of not only the JAK-STAT and helper T-cell pathways, but also less expected pathways governing the spliceosome, osteoclast differentiation, and coagulation pathways. Utilizing a specific inhibitor and gene-deficient mice, we demonstrate that STAT6 is required for mycosis-induced sinus inflammation. These findings confirm the relevance of this new model and portend future studies that further extend our understanding of the immunopathologic basis of airway mycosis and unified airway disease.

Abstract
In people with cystic fibrosis (PwCF), viscous sputum and dysfunction of the mucociliary escalator leads to early and chronic infections. The prevalence of Aspergillus fumigatus in sputum is high in PwCF and the contribution of A. fumigatus to the progression of structural lung disease has been reported. However, overall, relatively little is known about the contribution of A. fumigatus to CF lung disease. More knowledge is needed to aid clinical decisions on whether to start antifungal treatment. In this review, we give an overview of A. fumigatus colonisation and infection in PwCF and the different types of pulmonary disease caused by it. Furthermore, we discuss the current evidence for structural lung damage associated with A. fumigatus in PwCF on chest computed tomography and magnetic resonance imaging. We conclude that radiological outcomes to identify disease caused by A. fumigatus can be important for clinical studies and management.

Abstract
Allergic fungal rhinosinusitis (AFRS) has been considered an enigma since it was first described four decades ago. Previous research has found that AFRS has multiple definitions and a poorly understood pathogenesis because it overlaps with other conditions and necessitates meticulous work and multiple diagnostic modalities to confirm the diagnosis. However, despite the expansion of medical and surgical treatments, recurrence still occurs. In this review, the recent literature on AFRS cases in Saudi Arabia with relevance to its epidemiology, diagnosis, and management was studied and compared with international data. PubMed, Google Scholar, and Cochrane Library were searched for original research and review articles with local data. There is an evident paucity and contradiction between local studies regarding the epidemiology, diagnostic methods, and management of AFRS. Hence, well-defined randomized controlled trials (RCTs) are needed for the treatment of this chronic recurrent disease.

Abstract
Pollen and fungal spores are associated with seasonal and perennial allergies. However, most scientific literature thus far suggests that pollen allergy is more clinically relevant than fungal allergy. Several environmental and biological factors and the difficulty in producing reliable fungal extracts account for this. Biodiversity, taxonomy, and meteorology are responsible for the types and levels of pollen and fungal spores, their fragments, and the presence of free airborne allergens. Therefore, it is difficult to accurately measure both pollen and fungal allergen exposure. In addition, understanding the enzymatic nature of fungal and some pollen allergens, the presence of allergenic and nonallergenic substances that may modulate the allergic immune response, and allergen cross-reactivity are all necessary to appropriately evaluate both sensitivity and exposure. The raw materials and manufacturing processes used to prepare pollen versus fungal extracts differ, further increasing the complexity to properly determine allergic sensitivity and degrees of exposure. The pollen extracts used for diagnosis and treatment are relatively consistent, and some have been standardized. However, obtaining clinically relevant fungal extracts is more difficult. Doing so will allow for the proper selection of such extracts to more appropriately diagnose and treat both pollen- and fungal-induced allergic diseases.

Abstract
OBJECTIVE Allergic bronchopulmonary aspergillosis (ABPA) is classified radiologically as serologic ABPA (ABPA-S) or ABPA with central bronchiectasis (ABPA-CB). This retrospective case series study aimed to describe and compare the clinical characteristics of both forms of ABPA. METHODS Patients with ABPA treated in the hospital between February 2011 and June 2019 were enrolled and were divided into ABPA-S and ABPA-CB groups based on whether their cases were complicated with central bronchiectasis. Demographic data, symptoms, laboratory values, comorbidities, and image findings were collected. ABPA-S patients were followed up retrospectively through medical records. RESULTS Ninety-three (93) patients were enrolled, including 74 ABPA-CB patients and 19 ABPA-S patients. The most common predisposing condition was asthma (36.6%), with a median course of 30 years (IQR 13-42.5) prior to ABPA diagnosis. Patients of 54.8% had been misdiagnosed, with ABPA-S more likely than ABPA-CB to have been misdiagnosed as asthma (p < 0.01). Obstructive ventilation dysfunction and mixed ventilation dysfunction were found in 21 patients (22.6%) and 16 patients (17.2%), respectively. Compared with ABPA-S, ABPA-CB had a higher median blood eosinophil count (880 vs. 700 cells/μl), serum IgE (2957 vs. 2616 IU/ml), and Aspergillus fumigatus specific-IgE (20.6 vs. 7.31 kUA/L), although these findings were not statistically significant. Three ABPA-S patients developed bronchiectasis during follow-up and experienced relapses more than twice. CONCLUSIONS Our findings suggested that the clinical characteristics between ABPA-CB and ABPA-S were mostly similar. ABPA-S had a relatively lower immunological activity level than ABPA-CB but was still immunologically active and could develop bronchiectasis.

Abstract
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.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) has been reported in various degrees among patients with persistent allergic asthma (PAA). Currently, there is no gold standard approach for diagnosis of ABPA. OBJECTIVES In the current study, we aimed the evaluation of three different mainly used algorithms as Rosenberg & Patterson (A), ISHAM Working Group (B) and Greenberger (C) for diagnosis of ABPA in 200 patients with underlying PAA. METHODS All patients were evaluated using Aspergillus skin prick test (SPTAf), Aspergillus-specific IgE (sIgEAf) and IgG (sIgGAf), total IgE (tIgE), pulmonary function tests, radiological findings and peripheral blood eosinophil count. The prevalence rate of ABPA in PAA patients was estimated by three diagnostic criteria. We used Latent Class Analysis for the evaluation of different diagnostic parameters in different applied ABPA diagnostic algorithms. RESULTS Aspergillus sensitisation was observed in 30 (15.0%) patients. According to algorithms A, B and C, nine (4.5%), six (3.0%) and 11 (5.5%) of patients were diagnosed with ABPA, respectively. The sensitivity and specificity of criteria B and C were (55.6% and 99.5%) and (100.0% and 98.9%) respectively. sIgEAf and sIgGAf showed the high significant sensitivity. The performance of algorithm A, in terms of sensitivity and specificity, was somewhat better than algorithm B. CONCLUSION Our study demonstrated that the sensitivity of different diagnostic algorithms could change the prevalence rate of ABPA. We also found that all of three criteria resulted an adequate specificity for ABPA diagnosis. A consensus patterns combining elements of all three criteria may warrant a better diagnostic algorithm.

Evaluation of Cellular Responses for the Diagnosis of Allergic Bronchopulmonary Mycosis: A Preliminary Study in Cystic Fibrosis Patients. Front Immunol 2020; 10:3149.

Abstract
Background: Allergic bronchopulmonary mycosis (ABPM) is an underestimated allergic disease due to fungi. Most reported cases are caused by Aspergillus fumigatus (Af) and are referred to as allergic bronchopulmonary aspergillosis (ABPA). The main risk factor of ABPA is a history of lung disease, such as cystic fibrosis, asthma, or chronic obstructive pulmonary disease. The main diagnostic criteria for ABPA rely on the evaluation of humoral IgE and IgG responses to Af extracts, although these cannot discriminate Af sensitization and ABPA. Moreover, fungi other than Af have been incriminated. Flow cytometric evaluation of functional responses of basophils and lymphocytes in the context of allergic diseases is gaining momentum. Objectives: We hypothesized that the detection of functional responses through basophil and lymphocyte activation tests might be useful for ABPM diagnosis. We present here the results of a pilot study comparing the performance of these cellular assays vs. usual diagnostic criteria in a cystic fibrosis (CF) cohort. Methods: Ex vivo basophil activation test (BAT) is a diagnostic tool highlighting an immediate hypersensitivity mechanism against an allergen, e.g., through CD63 upregulation as an indirect measure of degranulation. Lymphocyte stimulation test (LST) relies on the upregulation of activation markers, such as CD69, after incubation with allergen(s), to explain delayed hypersensitivity. These assays were performed with Af, Penicillium, and Alternaria extracts in 29 adult CF patients. Results: BAT responses of ABPA patients were higher than those of sensitized or control CF patients. The highest LST result was for a woman who developed ABPA 3 months after the tests, despite the absence of specific IgG and IgE to Af at the time of the initial investigation. Conclusion: We conclude that basophil and lymphocyte activation tests could enhance the diagnosis of allergic mycosis, compared to usual humoral markers. Further studies with larger cohorts and addressing both mold extracts and mold relevant molecules are needed in order to confirm and extend the application of this personalized medicine approach.

Two Cases of Allergic Fungal Sinusitis with Differing Postoperative Course. Case Rep Otolaryngol 2019; 2019:9598283. [PMID: 31885992 PMCID: PMC6914952 DOI: 10.1155/2019/9598283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Accepted: 11/08/2019] [Indexed: 11/28/2022] Open
Abstract
Allergic fungal sinusitis (AFS) often develops in unilateral paranasal sinuses, which must be differentiated from tumors. When AFS develops on both sides, however, it must be differentiated from eosinophilic chronic sinusitis with evident eosinophilic infiltration at nasal/paranasal sinus mucosa; both conditions are highly recurrent and commonly considered intractable paranasal sinusitis. Surgical correction is the primary treatment method for AFS, as it is essential to connect the paranasal sinus communication to ensure exhaustive resection of the pathologic mucosa and for nasal steroids to reach each paranasal sinus. We recently encountered two AFS cases with differing postoperative courses. Case 1 showed evident exacerbation in the computed tomography findings, which suggests progression to eosinophilic sinusitis. Case 2 showed a benign prognosis without recurrence. Close long-term follow-up should be mandatory after surgery for the treatment of AFS.

Abstract
Asthma is a complex condition that affects 14% of the world's children and the approach to management includes both pharmacologic as well as non-pharmacologic strategies including attention to complex socioeconomic status phenomena. After an historical consideration of asthma, allergic and immunologic aspects of asthma in children and adolescents are presented. Concepts of socioeconomic aspects of asthma are considered along with environmental features and complications of asthma disparities. Also reviewed are links of asthma with mental health disorders, sleep disturbances and other comorbidities. A stepwise approach to asthma management is discussed that includes pharmacologic and non-pharmacologic strategies in the pediatric population. The role of immunotherapy and use of various immunomodulators are considered as well.

Abstract
Allergic fungal rhinosinusitis (AFRS) is a subset of chronic rhinosinusitis with nasal polyps (CRSwNP) characterized by antifungal IgE sensitivity, eosinophil-rich mucus (ie, allergic mucin), and characteristic computed tomographic and magnetic resonance imaging findings in paranasal sinuses. AFRS develops in immunocompetent patients, with occurrence influenced by climate, geography, and several identified host factors. Molecular pathways and immune responses driving AFRS are still being delineated, but prominent adaptive and more recently recognized innate type 2 immune responses are important, many similar to those established in patients with other forms of CRSwNP. It is unclear whether AFRS represents merely a more extreme expression of pathways important in patients with CRSwNP or whether there are other disordered immune responses that would define a distinct endotype or endotypes. Although AFRS and allergic bronchopulmonary aspergillosis share some analogous immune mechanisms, the 2 conditions do not occur commonly in the same patient. Treatment of AFRS almost always requires surgical debridement of the involved sinuses. Oral corticosteroids decrease recurrence after surgery, but other adjunctive pharmacologic agents, including topical and oral antifungal agents, do not have a firm evidence basis for use. There is good rationale for use of biologic agents that target eosinophilic inflammation or other type 2 responses, but studies in patients with AFRS are required.

Abstract
The allergic airway diseases, including chronic rhinosinusitis (CRS), asthma, allergic bronchopulmonary mycosis (ABPM) and many others, comprise a heterogeneous collection of inflammatory disorders affecting the upper and lower airways and lung parenchyma that represent the most common chronic diseases of humanity. In addition to their shared tissue tropism, the allergic airway diseases are characterized by a distinct pattern of inflammation involving the accumulation of eosinophils, type 2 macrophages, innate lymphoid cells type 2 (ILC2), IgE-secreting B cells, and T helper type 2 (Th2) cells in airway tissues, and the prominent production of type 2 cytokines including interleukin (IL-) 33, IL-4, IL-5, IL-13, and many others. These factors and related inflammatory molecules induce characteristic remodeling and other changes of the airways that include goblet cell metaplasia, enhanced mucus secretion, smooth muscle hypertrophy, tissue swelling and polyp formation that account for the major clinical manifestations of nasal obstruction, headache, hyposmia, cough, shortness of breath, chest pain, wheezing, and, in the most severe cases of lower airway disease, death due to respiratory failure or disseminated, systemic disease. The syndromic nature of the allergic airway diseases that now include many physiological variants or endotypes suggests that distinct endogenous or environmental factors underlie their expression. However, findings from different perspectives now collectively link these disorders to a single infectious source, the fungi, and a molecular pathogenesis that involves the local production of airway proteinases by these organisms. In this review, we discuss the evidence linking fungi and their proteinases to the surprisingly wide variety of chronic airway and systemic disorders and the immune pathogenesis of these conditions as they relate to environmental fungi. We further discuss the important implications these new findings have for the diagnosis and future therapy of these common conditions.

Abstract
Dr. Hinson and his colleagues first described allergic bronchopulmonary aspergillosis (ABPA) in 1952. Later in 1977, Rosenberg proposed a diagnostic criteria for ABPA that even today remains widely acknowledged. Despite these steps taken, there still isn't a standardized diagnostic criteria set for ABPA although many have been proposed by various physicians over the years. ABPA is a condition caused by hypersensitivity to Aspergillus fumigatus antigens. It is seen most commonly in patients with either asthma or cystic fibrosis. In susceptible hosts, repeated inhalation of Aspergillus spores can cause an allergic response. Although a standardized diagnostic criteria is required, there is no single test that establishes the diagnosis other than a demonstration of central bronchiectasis (CB) with normal tapering bronchi, a feature that is still considered pathognomonic of ABPA. Because of lack of standardized diagnostic criteria and screening, even today ABPA is under diagnosed and often times treatment for it is delayed. This can lead to complications in patients like pulmonary fibrosis, bronchiectasis with chronic sputum production, and increasingly severe persistent asthma with loss of lung function. For this alone, it becomes imperative that the diagnostic criteria guidelines need to be reviewed and standardized preferably with the help of larger research studies. In the following review article, we address the epidemiology, pathophysiology, and the current cumulative view regarding the diagnosis of ABPA.

Fungal extracts stimulate solitary chemosensory cell expansion in noninvasive fungal rhinosinusitis. Int Forum Allergy Rhinol 2019; 9:730-737. [PMID: 30892837 DOI: 10.1002/alr.22334] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2018] [Revised: 01/24/2019] [Accepted: 03/02/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Solitary chemosensory cells (SCCs) are rare epithelial cells enriched in nasal polyps and are the primary source of interleukin-25 (IL-25), an innate cytokine eliciting T-helper 2 (Th2) immune response. Although it is proposed that SCCs are stimulated by antigens released by upper airway pathogens, the exogenous triggers of human SCCs remain elusive. We studied patients with noninvasive fungal rhinosinusitis to determine whether extracts of Aspergillus fumigatus and Alternaria alternata stimulate SCC proliferation as an early event in type 2 inflammation. METHODS Multicolor flow cytometry, immunofluorescence, and enzyme-linked immunoassay were used to interrogate mucosa from patients with mycetomas and allergic fungal rhinosinusitis (AFRS) for SCCs and IL-25. Primary sinonasal epithelial cells from AFRS patients and noninflamed inferior turbinates were stimulated with fungal extracts for 72 hours, and SCC population frequency as well as mitotic activity were quantified using flow cytometry. RESULTS SCCs producing IL-25 are enriched in inflamed mucosa compared with intrapatient noninflamed control tissue (38.6% vs 6.5%, p = 0.029). In cultured sinonasal epithelial cells from AFRS nasal polyps, Aspergillus fumigatus and Alternaria alternata stimulated higher SCC frequency compared with controls (27.4% vs 10.6%, p = 0.002; 18.1% vs 10.6%, p = 0.046), which led to increased IL-25 secretion in culture media (75.5 vs 3.3 pg/mL, p < 0.001; 32.3 vs 3.3 pg/mL, p = 0.007). Ki-67 expression was higher in SCCs grown in fungal stimulation conditions compared with controls. CONCLUSION Although fungal antigens are known to potentiate immune response through innate cytokines, including IL-25, the early expansion of SCCs in the presence of fungus has not been described. This early event in the pathogenesis of noninvasive fungal rhinosinusitis may represent a target for intervention.

Abstract
Fungi are ubiquitous outdoors and indoors. Exposure, sensitization, or both to fungi are strongly associated with development of asthma and allergic airway diseases. Furthermore, global climate change will likely increase the prevalence of fungi and enhance their antigenicity. Major progress has been made during the past several years regarding our understanding of antifungal immunity. Fungi contain cell-wall molecules, such as β-glucan and chitin, and secrete biologically active proteases and glycosidases. Airway epithelial cells and innate immune cells, such as dendritic cells, are equipped with cell-surface molecules that react to these fungal products, resulting in production of cytokines and proinflammatory mediators. As a result, the adaptive arm of antifungal immunity, including TH1-, TH2-, and TH17-type CD4+ T cells, is established, reinforcing protection against fungal infection and causing detrimental immunopathology in certain subjects. We are only in the beginning stages of understanding the complex biology of fungi and detailed mechanisms of how they activate the immune response that can protect against or drive diseases in human subjects. Here we describe our current understanding with an emphasis on airway allergic immune responses. The gaps in our knowledge and desirable future directions are also discussed.

Abstract
OBJECTIVE To describe key diagnostic considerations in patients with pulmonary infiltrates with eosinophilia, with a special emphasis on raising awareness of hypereosinophilic syndrome (HES), a disease that often involves the lungs and prompts investigation for clonal neoplastic processes that determine prognosis and treatment. DATA SOURCES Studies and review articles were selected from PubMed and Scopus for relevance to pertinent topics. STUDY SELECTIONS The literature was screened for studies that described lung eosinophilia and HES. Studies relevant to the topic were included in this review. RESULTS Pulmonary eosinophil infiltrates in lung biopsy specimens present a broad differential diagnosis, including eosinophilic pneumonia; hypersensitivity reactions, such as allergic bronchopulmonary fungal disease; and pulmonary manifestations of systemic diseases, such as eosinophilic granulomatosis with polyangiitis. An additional important consideration in the differential diagnosis is pulmonary involvement by HES. HES is a rare syndrome that comprises a heterogeneous group of conditions characterized by persistent blood and/or tissue eosinophilia associated with organ dysfunction. Approximately one-third of HES cases are caused by neoplastic diseases, with the remaining cases classified as reactive or idiopathic. Lung involvement is seen in up to 67% of cases and may be the presenting manifestation of the disorder. CONCLUSION The differential diagnosis of pulmonary eosinophilia is broad and requires a multidisciplinary approach with clinicopathologic-radiologic correlation.

Abstract
Severe asthma is problematic and its pathogenesis poorly understood. Fungal sensitization is common, and many patients with severe asthma with fungal sensitization (SAFS), used to denote this subgroup of asthma, respond to antifungal therapy. We have investigated 325 haplotype-tagging SNPs in 22 candidate genes previously associated with aspergillosis in patients with SAFS, with comparisons in atopic asthmatics and healthy control patients, of whom 47 SAFS, 279 healthy and 152 atopic asthmatic subjects were genotyped successfully. Significant associations with SAFS compared with atopic asthma included Toll-like receptor 3 (TLR3) (p = .009), TLR9 (p = .025), C-type lectin domain family seven member A (dectin-1) (p = .043), interleukin-10 (IL-10) (p = .0010), mannose-binding lectin (MBL2) (p = .007), CC-chemokine ligand 2 (CCL2) (2 SNPs, p = .025 and .041), CCL17 (p = .002), plasminogen (p = .049) and adenosine A2a receptor (p = .024). These associations differ from those found in ABPA in asthma, indicative of contrasting disease processes. Additional and broader genetic association studies in SAFS, combined with experimental work, are likely to contribute to our understanding of different phenotypes of problematic asthma.

Abstract
BACKGROUND Fungi have been known to cause a variety of respiratory conditions, ranging from mold- associated asthma to allergic bronchopulmonary mycosis and invasive disease. More recently some fungal species have been implicated in a non-asthmatic chronic cough syndrome. CASE PRESENTATION A 59-year-old male presented to the pulmonary clinic with chronic nonproductive cough. Workup included pulmonary function tests with methacholine challenge, sputum cultures, CT scans of the chest and therapeutic trial with proton pump inhibitors. Sputum cultures repeatedly showed Saccharomyces cerevisiae and patient had elevated specific IgA and IgG. Bronchoscopy was unremarkable, except for tracheal mucosa biopsies revealing acute and chronic inflammation. A one-month course of steroids provided temporary relief of chronic cough, but symptoms returned once steroids were discontinued. He also experienced temporary relief away from home. Upon further evaluation, the patient described his hobby of wine making which was believed to be the source of Saccharomyces cerevisiae. Once he stopped wine making at home and cleared his cellar, his symptoms stopped and have not returned since. CONCLUSION We describe a rare presentation of non-asthmatic chronic cough associated with exposure to Saccharomyces cerevisiae. This is the first report of fungi associated chronic cough without asthmatic features outside of Japan and the first one associated with Saccharomyces cerevisiae. This report provides further evidence linking fungi with chronic cough syndrome without the features of asthma or allergic bronchopulmonary mycosis.

Abstract
Allergic fungal rhinosinusitis (AFRS) is a unique variety of chronic polypoid rhinosinusitis usually in atopic individuals, characterized by presence of eosinophilic mucin and fungal hyphae in paranasal sinuses without invasion into surrounding mucosa. It has emerged as an important disease involving a large population across the world with geographic variation in incidence and epidemiology. The disease is surrounded by controversies regarding its definition and etiopathogenesis. A working group on "Fungal Sinusitis" under the International Society for Human and Animal Mycology (ISHAM) addressed some of those issues, but many questions remain unanswered. The descriptions of "eosinophilic fungal rhinosinusitis" (EFRS), "eosinophilic mucin rhinosinusitis" (EMRS) and mucosal invasion by hyphae in few patients have increased the problem to delineate the disease. Various hypotheses exist for etiopathogenesis of AFRS with considerable overlap, though recent extensive studies have made certain in depth understanding. The diagnosis of AFRS is a multi-disciplinary approach including the imaging, histopathology, mycology and immunological investigations. Though there is no uniform management protocol for AFRS, surgical clearing of the sinuses with steroid therapy are commonly practiced. The role of antifungal agents, leukotriene antagonists and immunomodulators is still questionable. The present review covers the controversies, recent advances in pathogenesis, diagnosis, and management of AFRS.
