Liu F, Zeng M, Zhou X, Huang F, Song Z. Aspergillus fumigatus escape mechanisms from its harsh survival environments. Appl Microbiol Biotechnol 2024; 108:53. [PMID: 38175242 DOI: 10.1007/s00253-023-12952-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 10/09/2023] [Accepted: 10/19/2023] [Indexed: 01/05/2024]
Abstract
Aspergillus fumigatus is a ubiquitous pathogenic mold and causes several diseases, including mycotoxicosis, allergic reactions, and systemic diseases (invasive aspergillosis), with high mortality rates. In its ecological niche, the fungus has evolved and mastered many reply strategies to resist and survive against negative threats, including harsh environmental stress and deficiency of essential nutrients from natural environments, immunity responses and drug treatments in host, and competition from symbiotic microorganisms. Hence, treating A. fumigatus infection is a growing challenge. In this review, we summarized A. fumigatus reply strategies and escape mechanisms and clarified the main competitive or symbiotic relationships between A. fumigatus, viruses, bacteria, or fungi in host microecology. Additionally, we discussed the contemporary drug repertoire used to treat A. fumigatus and the latest evidence of potential resistance mechanisms. This review provides valuable knowledge which will stimulate further investigations and clinical applications for treating and preventing A. fumigatus infections. KEY POINTS: • Harsh living environment was a great challenge for A. fumigatus survival. • A. fumigatus has evolved multiple strategies to escape host immune responses. • A. fumigatus withstands antifungal drugs via intrinsic escape mechanisms.

Fractional exhaled nitric oxide, a potential biomarker for evaluating glucocorticoids treatment and prognosis in allergic bronchopulmonary aspergillosis. Ann Allergy Asthma Immunol 2024; 133:168-176.e1. [PMID: 38777120 DOI: 10.1016/j.anai.2024.05.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Revised: 05/12/2024] [Accepted: 05/13/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is characterized by enhanced TH2 inflammatory response. Fractional exhaled nitric oxide (FeNO) measurement has been used as a valuable tool in predicting the development and management of asthma, another typical TH2 inflammation. However, the clinical significance of FeNO in ABPA remains unclear. OBJECTIVE To investigate the association between FeNO and the prognosis of patients with ABPA to provide a basis for the use of FeNO in evaluating the efficacy of glucocorticoids in ABPA treatment. METHODS This study comprised 2 parts; 58 patients were enrolled in the retrospective study. Clinical indexes in patients with different prognoses were compared, and receiver operating characteristic curve analysis was used to determine the threshold value. The prospective observational study involved 61 patients who were regularly followed up at 4 to 6 weeks and 6 months since the initial treatment. Patients were grouped on the basis of baseline FeNO values; correlation analysis was performed in the clinical data. RESULTS Different prognoses were observed between patients with high and low baseline FeNO values, with a threshold value of 57 parts per billion. The percentage of Aspergillus fumigatus-specific IgE, percentage of positive A fumigatus-specific IgG, and relapse/exacerbation rate differed significantly between the high and low FeNO groups. Patients with higher FeNO needed longer treatment duration and showed shorter interval between glucocorticoid withdrawal and the next relapse/exacerbation. CONCLUSION Our findings indicate that the level of FeNO is associated with the prognosis of ABPA. It can serve as an independent and valuable biomarker for evaluating the effectiveness of glucocorticoid treatment.

Abstract
BACKGROUND Treatment of allergic bronchopulmonary aspergillosis (ABPA) is challenging. Biological therapies have been reported as adjunctive treatments for ABPA, primarily in case series or case reports. This study aimed to analyze the efficacy of biologics for managing ABPA both qualitatively and quantitatively. METHODS All articles on APBA published in October 2023 were searched in PubMed, Web of Science, ClinicalTrials.gov, and Embase databases. The effects of interest were the mean changes from baseline for outcomes, including exacerbation rates, oral corticosteroids usage (OCS), and total immunoglobulin E (IgE) levels. Reported outcomes were quantitatively synthesized by usual or individual patient data (IPD) meta-analyses. PROSPERO registration number: CRD42022373396. RESULTS A total of 86 studies were included in the systematic review including 346 patients. Sixteen studies on omalizumab were pooled for the usual meta-analysis. Omalizumab therapy significantly reduced exacerbation rates (- 2.29 [95%CI - 3.32, - 1.26]), OCS dosage (- 10.91 mg [95%CI - 18.98, - 2.85]), and total IgE levels (- 273.07 IU/mL [95%CI - 379.30, - 166.84]), meanwhile improving FEV1% predicted (10.09% [95%CI 6.62, 13.55]). Thirty-one studies on dupilumab, mepolizumab, or benralizumab were pooled to perform an IPD meta-analysis, retrospectively. Both dupilumab and mepolizumab significantly reduced exacerbation rates, OCS, and total IgE levels. Benralizumab showed a similar trend, but it was not statistically significant. Tezepelumab showed weak evidence of its effects on ABPA. All five biologics led to milder clinical symptoms (e.g., cough, wheezing) with serious adverse effects that happened once in omalizumab treatment. CONCLUSION These results indicate the clinical benefit of omalizumab, dupilumab, and mepolizumab in patients with ABPA. Further randomized, controlled studies with a larger sample size and longer follow-up are needed to confirm these findings.

Abstract
INTRODUCTION Allergic bronchopulmonary aspergillosis (ABPA) is a lung disease caused by a hypersensitivity reaction to antigens of Aspergillus fumigatus. OBJECTIVE The aim of this study was to evaluate the long-term clinical outcomes of omalizumab use in patients with ABPA. METHODS In this retrospective study, 12 patients diagnosed with ABPA and receiving omalizumab for at least 2 years, and 32 patients diagnosed with severe allergic asthma and receiving omalizumab for at least 2 years (control group) were evaluated. RESULTS Evaluation was made of a total of 44 participants, comprising 11 (25%) males and 33 (75%) females, who received omalizumab for at least 2 years with the diagnosis of the control group (n = 32) and ABPA (n = 12). The increase in asthma control test (ACT) score after omalizumab was significant at 12 months and at 24 months in patients with ABPA. After omalizumab, the use of oral corticosteroid (OCS), the annual number of asthma attacks and hospitalizations were significantly decreased at 12 months and at 24 months in patients with ABPA. The increase in forced expiratory volume in 1 s (FEV1) (%) and ACT score after omalizumab were significant at 12 months and at 24 months in the control group. After omalizumab, the use of OCS, annual number of asthma attacks and hospitalizations were significantly decreased at 12 months and at 24 months in the control group. CONCLUSION Long-term omalizumab use in patients with ABPA seems to be an effective treatment for improving pulmonary function and reducing asthma exacerbations and hospitalizations.

Abstract
This case study describes a unique scenario in which allergic bronchopulmonary aspergillosis (ABPA) was identified following treatment for pulmonary tuberculosis (PTB). ABPA is a complex pulmonary disorder that is often overlooked due to its nonspecific clinical presentation, especially in individuals concurrently diagnosed with tuberculosis (TB). Despite initial TB diagnosis and treatment, a 28-year-old male continued to experience respiratory symptoms, prompting further investigation that revealed underlying ABPA. This case underscores the importance of emphasizing the critical role of maintaining a high level of suspicion for ABPA in TB patients with persistent symptoms, highlighting the need for timely recognition and management to minimize further lung damage and improve patient outcomes.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are diseases caused by Aspergillus infection, and CPA can develop from ABPA in some cases. We herein report a patient with CPA overlapping with ABPA. Serum cytokine levels were evaluated at 4 time points: the ABPA diagnosis, CPA diagnosis, 6 months after the start of voriconazole (VRCZ), and 12 months after re-administration of VRCZ. Interleukin (IL)-13 levels decreased upon glucocorticoid treatment, whereas IL-25 and IL-33 levels decreased rapidly with the initiation of antifungals. Early antifungal therapy may be important to control disease progression and prevent CPA overlap.

Abstract
Radiological imaging has proven to be a useful tool in the assessment of asthma, its comorbidities and potential complications. Characteristic chest radiograph and computed tomography scan findings can be seen in asthma and in other conditions that can coexist with or be misdiagnosed as asthma, including chronic rhinosinusitis, inducible laryngeal obstruction, excessive dynamic airway collapse, tracheobronchomalacia, concomitant COPD, bronchiectasis, allergic bronchopulmonary aspergillosis, eosinophilic granulomatosis with polyangiitis, and eosinophilic pneumonia. The identification of the characteristic radiological findings of these conditions is often essential in making the correct diagnosis and provision of appropriate management and treatment. Furthermore, radiological imaging modalities can be used to monitor response to therapy.

Abstract
INTRODUCTION Patients with allergic bronchopulmonary aspergillosis (ABPA) suffer from repeated exacerbations. The involvement of T-cell subsets remains unclear. METHODS We enrolled ABPA patients, asthma patients and healthy controls. T-helper type 1 (Th1), 2 (Th2) and 17 (Th17) cells, regulatory T-cells (Treg) and interleukin (IL)-21+CD4+T-cells in total or sorted subsets of peripheral blood mononuclear cells and ABPA bronchoalveolar lavage fluid (BALF) were analysed using flow cytometry. RNA sequencing of subsets of CD4+T-cells was done in exacerbated ABPA patients and healthy controls. Antibodies of T-/B-cell co-cultures in vitro were measured. RESULTS ABPA patients had increased Th2 cells, similar numbers of Treg cells and decreased circulating Th1 and Th17 cells. IL-5+IL-13+IL-21+CD4+T-cells were rarely detected in healthy controls, but significantly elevated in the blood of ABPA patients, especially the exacerbated ones. We found that IL-5+IL-13+IL-21+CD4+T-cells were mainly peripheral T-helper (Tph) cells (PD-1+CXCR5-), which also presented in the BALF of ABPA patients. The proportions of circulating Tph cells were similar among ABPA patients, asthma patients and healthy controls, while IL-5+IL-13+IL-21+ Tph cells significantly increased in ABPA patients. Transcriptome data showed that Tph cells of ABPA patients were Th2-skewed and exhibited signatures of follicular T-helper cells. When co-cultured in vitro, Tph cells of ABPA patients induced the differentiation of autologous B-cells into plasmablasts and significantly enhanced the production of IgE. CONCLUSION We identified a distinctly elevated population of circulating Th2-skewed Tph cells that induced the production of IgE in ABPA patients. It may be a biomarker and therapeutic target for ABPA.

Phadnis S, Muthu V, Sehgal IS, Prasad KT, Dhooria S, Aggarwal AN, Agarwal R. Bronchiectasis Severity Index and FACED scores in patients with allergic bronchopulmonary aspergillosis complicating asthma: do they correlate with immunological severity or high-attenuation mucus? J Asthma 2024:1-9. [PMID: 38520686 DOI: 10.1080/02770903.2024.2334901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Accepted: 03/20/2024] [Indexed: 03/25/2024]
Abstract
Background: The utility of two disease-severity indices, namely bronchiectasis severity index (BSI) and FACED score in allergic bronchopulmonary aspergillosis (ABPA) remains unknown.Objective: To correlate the BSI and FACED scores with immunological parameters (serum IgE [total and A. fumigatus-specific], A. fumigatus-specific IgG, blood eosinophil count), and high-attenuation mucus on chest computed tomography in ABPA. The secondary objectives were to evaluate the correlation between BSI and FACED scores and correlate the BSI/FACED scores with the bronchiectasis health questionnaire (BHQ) and Saint George's Respiratory Questionnaire (SGRQ).Methods: We included treatment-naïve ABPA subjects with bronchiectasis in a prospective observational study. We computed the BSI and FACED scores for each subject before initiating treatment. The subjects also completed two quality-of-life questionnaires (BHQ and SGRQ).Results: We included 91 subjects. The mean (standard deviation) BSI and FACED scores were 3.43 (3.39) and 1.43 (1.27). We found no correlation between BSI or FACED with any immunological parameter or high-attenuation mucus. There was a strong correlation between BSI and FACED scores (r = 0.76, p < 0.001). We found a weak correlation between BSI and BHQ/SGRQ and FACED and SGRQ.Conclusion: We found no correlation between BSI and FACED with immunological parameters in ABPA. However, we found a significant correlation between BSI and FACED and a weak correlation between SGRQ and BHQ. ABPA likely requires a separate disease-severity scoring system.

Abstract
Pulmonary infiltrates with eosinophilia are a heterogeneous group of disorders that are characterized by pulmonary infiltrates on chest radiograph and elevated levels of eosinophils in the peripheral blood. Among patients with these disorders, reports of either allergic bronchopulmonary aspergillosis (ABPA) or tropical pulmonary eosinophilia (TPE) are common. However, the simultaneous occurrence of ABPA and TPE is not often reported. We present the case of a young man with a history of asthma who was diagnosed with ABPA and TPE. Initially, the patient exhibited a partial response to treatment of ABPA, but persistent symptoms and eosinophilia led to suspicion and subsequent diagnosis of TPE. With implementation of antifilarials and steroids, the patient experienced satisfactory clinical and serological improvements. This case underscores the importance of considering multiple diagnoses in patients with overlapping symptoms and highlights the need for comprehensive management strategies in complex lung diseases.

Abstract
Understanding the immune response to Aspergillus fumigatus, a common cause of invasive fungal infections (IFIs) in immunocompromised individuals, is critical for developing effective treatments. Tcells play a critical role in the immune response to A. fumigatus, with different subsets having distinct functions. Th1 cells are important for controlling fungal growth, while Th2 cells can exacerbate infection. Th17 cells promote the clearance of fungi indirectly by stimulating the production of various antimicrobial peptides from epithelial cells and directly by recruiting and activating neutrophils. Regulatory T cells have varied functions in A.fumigatus infection. They expand after exposure to A. fumigatus conidia and prevent organ injury and fungal sepsis by downregulating inflammation and inhibiting neutrophils or suppressing Th17 cells. Regulatory T cells also block Th2 cells to stop aspergillosis allergies. Immunotherapy with CAR T cells is a promising treatment for fungal infections, including A. fumigatus infections, especially in immunocompromised individuals. However, further research is needed to fully understand the mechanisms underlying the immune response to A. fumigatus and to develop effective immunotherapies with CAR-T cells for this infection. This literature review explores the role of Tcell subsets in A.fumigatus infection, and the effects of CAR-T cell therapy on this fungal infection.

Abstract
The filamentous fungus Aspergillus causes a wide spectrum of diseases in the human lung, with Aspergillus fumigatus being the most pathogenic and allergenic subspecies. The broad range of clinical syndromes that can develop from the presence of Aspergillus in the respiratory tract is determined by the interaction between host and pathogen. In this review, an oversight of the different clinical entities of pulmonary aspergillosis is given, categorized by their main pathophysiological mechanisms. The underlying immune processes are discussed, and the main clinical, radiological, biochemical, microbiological, and histopathological findings are summarized.

Abstract
Aspergillus fumigatus is a common causative pathogen of aspergillosis. At present, triazole resistance of A. fumigatus poses an important challenge to human health globally. In this study, the biological characteristics and mechanisms of azole resistance of five A. fumigatus strains (AF1, AF2, AF4, AF5, and AF8) were explored. There were notable differences in the sporulation and biofilm formation abilities of the five test strains as compared to the standard strain AF293. The ability of strain AF1 to avoid phagocytosis by MH-S cells was significantly decreased as compared to strain AF293, while that of strains AF2, AF4, and AF5 were significantly increased. Fungal burden analysis with Galleria mellonella larvae revealed differences in pathogenicity among the five strains. Moreover, the broth microdilution and E-test assays confirmed that strains AF1 and AF2 were resistant to itraconazole and isaconazole, while strains AF4, AF5, and AF8 were resistant to voriconazole and isaconazole. Strains AF1 and AF2 carried the cyp51A mutations TR34/L98H/V242I/S297T/F495I combined with the hmg1 mutation S541G, whereas strains AF4 and AF8 carried the cyp51A mutation TR46/Y121F/V242I/T289A, while strain AF5 had no cyp51A mutation. Real-time quantitative polymerase chain reaction (RT-qPCR) analysis revealed differences in the expression levels of genes associated with ergosterol synthesis and efflux pumps among the five strains. In addition, transcriptomics, RT-qPCR, and the NAD+/NADH ratio demonstrated that the mechanism of voriconazole resistance of strain AF5 was related to overexpression of genes associated with energy production and efflux pumps. These findings will help to further elucidate the triazole resistance mechanism in A. fumigatus.

Abstract
A 55-year-old female presented with recent exacerbation of the chronic cough, dyspnea, and copious expectoration. The symptoms worsened during the winter months. In the past, she was misdiagnosed with pulmonary tuberculosis. A computed tomography scan revealed bronchiectasis changes, high attenuated mucus, and hypereosinophilia. The diagnosis of Allergic Bronchopulmonary Aspergillosis (ABPA) with subacute invasion was confirmed through bronchoscopy and fungal culture. Treatment with oral voriconazole significantly improved lung function and quality of life. This case highlights the importance of considering invasive pulmonary aspergillosis in patients with exacerbations of asthma and bronchiectasis. Early diagnosis and appropriate treatment are essential for improved outcomes in such cases.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction to Aspergillus fumigatus that occurs in patients with asthma or cystic fibrosis. Here, we report a case of a young female with bronchial asthma who presented to our hospital with worsening breathlessness on exertion. She was diagnosed to have ABPA and was initiated on oral itraconazole while continuing inhaled long acting beta-2 adrenergic agonist and medium dose inhaled corticosteroid (ICS) for her asthma. Three months after initiation of therapy, the patient had significant improvement in breathlessness. However, she had weight gain, facial puffiness, increased facial hair and development of striae on her inner thighs, calf and lower abdomen. Her serum cortisol levels were found to be suppressed and hence a diagnosis of iatrogenic Cushing's syndrome was made. Our case describes the potentially serious interaction between ICS and oral itraconazole, a treatment very commonly prescribed in patients with ABPA.

Abstract
BACKGROUND Hitherto, the bulk of diagnostic criteria regards Aspergillus-specific immunoglobulin E as a key item, and regard IgG as an auxiliary method in diagnose. Nevertheless, there is no conclusive study in summarize the performance of IgG and IgE diagnosing ABPA. METHODS We conducted a systematic review to identify studies report results of IgE and IgG detection in diagnosing ABPA. QUADAS-2 tool was used to evaluate included studies, and we applied the HSROC model to calculate the pooled sensitivity and specificity. Deeks' funnel was derived to evaluated the public bias of included studies, and Cochrane Q test and I2 statistic were used to test the heterogeneity. RESULTS Eleven studies were included in this study (1127 subjects and 215 for IgE and IgG). Deeks's test for IgE and IgG were 0.10 and 0.19. The pooled sensitivity and specificity for IgE were 0.83 (95%CI: 0.77, 0.90) and 0.89 (0.83, 0.94), and for IgG were 0.93 (0.87, 0.97) and 0.73 (0.62,0.82), with P value < 0.001. The PLR and NLR for IgE were 7.80 (5.03,12.10) and 0.19 (0.13,0.27), while for IgG were 3.45 (2.40,4.96) and 0.09 (0.05,0.17). The combined diagnostic odds ratio and diagnostic score were 41.49 (26.74,64.36) and3.73 (3.29,4.16) for IgE, respectively, and were 38.42 (19.23,76.79) and 3.65 (2.96,4.34) for IgG. CONCLUSION The sensitivity for IgG diagnosing ABPA is higher than IgE, while the specificity for IgE is higher. IgG might be able to play a more important role in filtering ABPA patients.

Abstract
Fungal sensitization is highly prevalent in severe asthma. The relationship between fungus and asthma, especially Aspergillus fumigatus, has been the subject of extensive research. The ubiquitous presence of A. fumigatus, its thermotolerant nature, the respirable size of its conidia, and its ability to produce potent allergens are pivotal in worsening asthma control. Due to the diverse clinical manifestations of fungal asthma and the lack of specific biomarkers, its diagnosis remains intricate. Diagnosing fungal asthma requires carefully assessing the patient's clinical history, immunological tests, and imaging. Depending on the severity, patients with fungal asthma require personalized treatment plans, including inhaled corticosteroids and bronchodilators, and antifungal therapy. This review provides a comprehensive overview of the association between Aspergillus and asthma by reviewing the relevant literature and highlighting key findings. We discuss the diagnosis of various entities included in fungal asthma. We also debate whether newer definitions, including allergic fungal airway disease, offer any additional advantages over the existing ones. Finally, we provide the current treatment options for the individual entities, including A. fumigatus-associated asthma, severe asthma with fungal sensitization, and allergic bronchopulmonary mycoses.

Abstract
Allergic fungal airway diseases are associated with asthma exacerbations and poor control. However, the early identification of allergic Aspergillus airway diseases can be challenging, especially in resource-poor countries. We aimed to evaluate the clinical utility of the point-of-care Aspergillus IgG-IgM lateral flow assay in diagnosing Aspergillus airway diseases in patients with moderate-severe asthma. Patients with moderate-severe asthma, severe asthma with fungal sensitisation (SAFS) and allergic bronchopulmonary aspergillosis (ABPA) were recruited. Clinical information was extracted from clinical records. Blood samples were collected for serological tests. Serum samples were evaluated using Aspergillus immunochromatographic test (ICT). A total of 65 patients were recruited into the study, of whom 23.1% had clinical diagnosis of ABPA, 18.5% had SAFS and 58.5% had moderate-to-severe asthma who did not fit ABPA or SAFS criteria. The ICT test gave a sensitivity of 69 [95% confidence interval: 51-88]% and a specificity of 77 [60-88]% in predicting a positive Aspergillus IgG test. The sensitivity and specificity for a positive Aspergillus IgE were 77 [59-88]% and 86 [71-94]%, respectively. The majority (sensitivity: 87 [62-96]%) of patients with ABPA had positive ICT results, with a specificity of 70%. The negative predictive value was high (95 [82-99]%) with a low negative likelihood ratio (< 0.2), making it potentially useful in ruling out ABPA. The ICT assay may be valuable in ruling out ABPA in resource-limited countries where serological investigations are less feasible. The ICT assay may be particularly useful in ruling out ABPA and warrants further validation.

Abstract
Patients with allergic bronchopulmonary aspergillosis (ABPA), a hypersensitivity reaction to Aspergillus fumigatus, typically present with asthma; the common imaging findings are central bronchiectasis, mucoid impaction, and tree-in-bud opacities. In this report, we discuss the case of a heavy smoker who presented with a large pulmonary mass that was initially presumed to be primary lung cancer and who was ultimately diagnosed with ABPA, which responded favorably to steroid treatment.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an allergic fungal disease that commonly complicates the natural course of patients with asthma and cystic fibrosis. Patients with ABPA commonly present with recurrent pulmonary infiltrates or bronchiectasis. They also experience difficulty treating asthma. Characteristic radiological findings include central bronchiectasis and high-attenuation mucus. Complete unilateral lung collapse is an uncommon presentation of ABPA, with few cases reported in published literature. We present a case of a man in his mid-40s, with acute cerebrovascular disease, who subsequently developed neurological deterioration, compounded by development of respiratory failure attributed to a complete left lung collapse, requiring invasive mechanical ventilation. Initially suspected to have aspiration pneumonia, he was eventually diagnosed with ABPA and was treated accordingly. This case illustrates an uncommon aetiology for complete lung collapse in this clinical setting and serves to remind us to consider ABPA as a differential diagnosis in such patients as well.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an underdiagnosed lung condition in patients with asthma and cystic fibrosis. Its clinical and diagnostic manifestations result from an allergic response to multiple antigens expressed by Aspergillus fumigatus, which colonize the bronchial mucus. This report presents the case of a 73-year-old female patient referred to our hospital for uncontrolled asthma for 35 years. The diagnosis of ABPA was made on the basis of clinical symptoms, peripheral blood eosinophilia, elevated total serum immunoglobulin E, positive aspergillus serology, and bronchiectasis with mucoid impaction. Systemic corticosteroids and antifungal therapy came up with satisfactory clinical results.

Abstract
Despite standard treatment with systemic corticosteroids and/or antifungal triazoles, a substantial proportion of patients with allergic bronchopulmonary aspergillosis (ABPA) experience frequent relapses and require long-term treatment despite unfavorable adverse effects. We investigated the efficacy and safety of anti-interleukin (IL)-5/IL-5 receptor α chain (Rα) monoclonal antibodies (mAbs) in patients with ABPA complicated by asthma. ABPA cases treated with anti-IL-5/IL-5Rα mAbs were collected from 132 medical institutes in 2018 and published case reports in Japan. Clinical outcomes, laboratory and physiological data, and radiographic findings during 32 weeks before and after treatment were retrospectively evaluated. We analyzed 29 cases of ABPA: 20 treated with mepolizumab and nine with benralizumab. Treatment with anti-IL-5/IL-5Rα mAbs reduced the frequency of exacerbations (p = 0.03), decreased the dose of oral corticosteroids (p < 0.01), and improved pulmonary function (p = 0.01). Mucus plugs in the bronchi shrank or diminished in 18 patients (82%). Despite the clinical/radiographical improvement, serum levels of total IgE, the key biomarker for the pharmacological response in ABPA, were unchanged. Anti-IL-5/IL-5Rα mAbs that directly target eosinophils are promising candidates for the treatment of patients with ABPA, especially those with mucus plugs in the bronchi.

Abstract
BACKGROUND An unmet clinical need exists in the management of treatment-refractory allergic bronchopulmonary aspergillosis (ABPA). Omalizumab has shown promising effects in case series and cohort studies; however, evidence to support its routine clinical use is lacking. OBJECTIVE The aim of this systematic review and meta-analysis was to evaluate the clinical effectiveness and safety of omalizumab in patients with ABPA. METHODS We conducted a systematic search across standard databases using specific key words until May 13, 2021. We performed a meta-analysis to compare the effectiveness (exacerbations, oral corticosteroid [OCS] use, lung function, and patient-reported asthma control) and safety of pre- and post-omalizumab treatment. Subgroup analyses were performed for treatment duration and underlying disease. RESULTS In total, 49 studies (n = 267) were included in the qualitative synthesis and 14 case series (n = 186) in the quantitative meta-analysis. Omalizumab treatment significantly reduced the annualized exacerbation rate compared with pretreatment (mean difference, -2.09 [95% CI, -3.07 to -1.11]; P < .01). There was a reduction in OCS use (risk difference, 0.65 [95% CI, 0.46-0.84]; P < .01), an increase in termination of OCS use (risk difference, 0.53 [95% CI, 0.24-0.82]; P < .01), and a reduction in OCS dose (milligrams per day) (mean difference, -14.62 [95% CI, -19.86 to -9.39]; P < .01) in ABPA patients receiving omalizumab. Omalizumab improved FEV1 % predicted by 11.9% (95% CI, 8.2-15.6; P < .01) and asthma control, and was well-tolerated. CONCLUSIONS Omalizumab treatment reduced exacerbations and OCS use, improved lung function and asthma control in patients with ABPA, and was well-tolerated. The results highlight the potential role of omalizumab in the treatment of ABPA.

Abstract
A male patient in his 20s presented with a cough and a small volume of haemoptysis that lasted a year. He had no other constitutional symptoms and a respiratory examination was suggestive of a consolidation. A chronic infection, such as tuberculosis, was suspected. The routine evaluation showed peripheral eosinophilia with raised serum total IgE. Sputum examination for tuberculosis was negative; hence, a high-resolution CT of the thorax was performed, which revealed bilateral bronchiectasis with high-attenuation mucus plugging. The imaging and blood profiles were in favour of allergic bronchopulmonary aspergillosis, but there was no history suggestive of asthma, and the pulmonary function test was normal. The patient underwent a skin prick test and an allergen-specific IgE test for Aspergillus fumigatus, and both were positive. His bronchoalveolar lavage cultures also grew A. fumigatus, and he responded well to antifungal therapy. This case illustrates the presentation of a rare entity-allergic bronchopulmonary aspergillosis sans asthma.

Abstract
Background: Eosinophils have a double-edged role in the human body, being essential in important physiologic functions but whose presence is conspicuous in a variety of diseases characterized by a T2 inflammation phenotype. Eosinophils are exquisitely sensitive to corticosteroids, and the latter have, until recently, represented the cornerstone of treatment of eosinophilic diseases. However, most patients remain dependent on oral corticosteroids, with a notable adverse effect burden and experience a chronic relapsing disease that leads to high morbidity and mortality. Treatment prospects have changed with the advent of biologic drugs that target the eosinotropic cytokine interleukin (IL) 5 or its receptor. The success of the latter drugs in severe eosinophilic asthma has paved the way for their use in other, rarer, eosinophilic lung diseases. Recently, mepolizumab, a humanized monoclonal antibody that works against IL-5, was approved for the add-on treatment of relapsing-remitting or refractory eosinophilic granulomatosis with polyangiitis (EGPA) in patients ages ≥ 6 years. Benralizumab, a humanized antibody that binds to the α portion of the IL-5 receptor, is also being tested for its efficacy in EGPA in two clinical trials, after a growing number of case reports and case series supported its use as a steroid-sparing agent in the treatment of EGPA. Methods: In this review, we summarized the scientific literature evaluating the efficacy of benralizumab treatment in patients afflicted with rare primary eosinophilic lung diseases. Results: The literature we found, largely case reports, reported that the use of benralizumab in EGPA, chronic eosinophilic pneumonia (CEP) and allergic bronchopulmonary aspergillosis (ABPA) often led to a depletion of eosinophils, less exacerbations and a decreased systemic corticosteroid burden. No adverse effects were reported. Conclusion: Benralizumab has a prospective role in the treatment of rare eosinophilic lung diseases, which needs to be further elucidated in randomized controlled trials.

Allergic bronchopulmonary aspergillosis is usually seen in patients with asthma or cystic fibrosis. Its association with rheumatic heart disease has not been adequately reported in literature. We report our experience of three cases who were diagnosed cases of rheumatic heart disease. Their symptomatology and clinical findings required further evaluation and investigations, which were suggestive of allergic bronchopulmonary aspergillosis. The patients were treated with steroids and/or antifungals before proceeding with the valve replacement.

Abstract
BACKGROUND The diagnostic accuracy of immunoassays versus immunoprecipitation methods for detecting A.fumigatus-specific IgG in patients with allergic bronchopulmonary aspergillosis (ABPA) complicating asthma remains unclear. METHODS We performed a systematic review to identify studies describing both the methods in the same ABPA subjects. We assessed study quality using the QUADAS-2 tool. We derived the relative sensitivity and specificity using the HSROC meta-regression model. We calculated the number-needed-to-test using an immunoassay to detect one additional positive test in ABPA. RESULTS Our search yielded 20 studies (796 ABPA, 929 controls). The studies had a high risk of bias. The summary estimates for sensitivity and specificity of immunoprecipitation methods were 68.6% (95% CI, 48.4-83.5) and 93.8% (95% CI, 83.6-97.8), while for immunoassays they were 85.2% (95% CI, 73.3-92.3) and 84.6% (95% CI, 76.0-90.5), respectively. The relative sensitivity and specificity of immunoassays compared to immunoprecipitation tests were 1.29 (95% CI, 1.1-1.6) and 0.91 (95% CI, 0.85-0.97), respectively. The automated immunoassays (1.77; 95% CI, 1.1-2.8) had better relative sensitivity than the manual (1.1; 95% CI, 1.02-1.18) assays compared to immunoprecipitation. The relative specificity of manual immunoassays (0.95; 95% CI, 0.91-0.99) was significantly lower, while that of automated (0.88; 95% CI, 0.77-1.0) assays was lower but not statistically different. One additional positive result was detected for every 6 (95% CI, 5-7) tests performed with immunoassay (versus immunoprecipitation). CONCLUSION Manual immunoassays have higher sensitivity and lower specificity, while automated immunoassays have higher sensitivity and similar specificity than immunoprecipitation methods for detecting A.fumigatus-IgG in patients with ABPA.

Abstract
Allergic bronchopulmonary aspergillosis is an uncommon condition characterized by airway hypersensitivity to Aspergillus fumigatus, resulting in worsening asthma control and bronchiectasis progression. It is associated with various radiological features. Here, we describe a 53-year-old lady with atypical CT chest finding as soft tissue density masses in both lungs evaluated initially as a lung tumour. The diagnosis was particularly challenging given the history of undiagnosed asthma. Nevertheless, bronchoscopy findings of mucus impaction and blood eosinophilia redirect the clinical thinking toward ABPA. Laboratory examination showed elevated total IgE, Aspergillus fumigatus IgE, and Aspergillus niger IgE. Shortly after treatments with systemic steroids, our patient showed a symptomatic improvement. Moreover, subsequent follow-up showed a resolution of the radiological opacities.

Abstract
Objective Early diagnosis of allergic bronchopulmonary aspergillosis (ABPA) and targeted treatment can block the process of the disease. This study explores the diagnostic value of CT radiomics combined with clinical features in allergic ABPA. Methods A total of 40 patients with ABPA were studied retrospectively, divided into training set (n = 28) and test set (n = 12). Based on CT imaging, the radiomics features are extracted and combined with clinical features to build a diagnostic model. The diagnosis model was based on support vector machine algorithm. The receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate the diagnostic efficiency of the model. Results There was no significant difference in general information and clinical data between the training and test sets (P > 0.05). The AUC of the training set and the test set is 0.896 (95% CI: 0.836-0.963) and 0.886 (95% CI: 0.821-0.952), respectively. Conclusion Based on the CT radiomics model combined with clinical data, it has high efficiency in the diagnosis of ABPA.

Serum Cytokines Usefulness for Understanding the Pathology in Allergic Bronchopulmonary Aspergillosis and Chronic Pulmonary Aspergillosis. J Fungi (Basel) 2022; 8:jof8050436. [PMID: 35628692 PMCID: PMC9147526 DOI: 10.3390/jof8050436] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 04/09/2022] [Accepted: 04/21/2022] [Indexed: 12/04/2022] Open
Abstract
Allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) are important fungal infections caused by Aspergillus species. An overlap of ABPA and CPA has been reported; therefore, it is critical to determine whether the main pathology is ABPA or CPA and whether antifungals are required. In this study, we investigated whether the serum cytokine profile is useful for understanding the pathology and for differentiating between these diseases. We compared the various serum cytokine levels among healthy subjects and patients diagnosed with asthma, ABPA, or CPA at Nagasaki University Hospital between January 2003 and December 2018. In total, 14 healthy subjects, 19 patients with asthma, 11 with ABPA, and 10 with CPA were enrolled. Interleukin (IL) -5 levels were significantly higher in patients with ABPA than in those with CPA, and IL-33 and tumor necrosis factor (TNF) levels were significantly higher in patients with CPA than in those with asthma (p < 0.05, Dunn’s multiple comparison test). The sensitivity and specificity of the IL-10/IL-5 ratio (cutoff index 2.47) for diagnosing CPA were 70% and 100%, respectively. The serum cytokine profile is useful in understanding the pathology of ABPA and CPA, and the IL-10/IL-5 ratio may be a novel supplemental biomarker for indicating the pathology of CPA.

Abstract
Asthma is a common chronic respiratory disease that affects millions of people worldwide. Patients with allergic asthma, the most prevalent asthma endotype, are widely considered to possess a defective immune response against some respiratory infectious agents, including viruses, bacteria and fungi. Furthermore, respiratory pathogens are associated with asthma development and exacerbations. However, growing data suggest that the immune milieu in allergic asthma may be beneficial during certain respiratory infections. Immunomodulatory asthma treatments, although beneficial, should then be carefully prescribed to avoid misuse and overuse as they can also alter the host microbiome. In this review, we summarize and discuss recent evidence of the correlations between allergic asthma and the most significant respiratory infectious agents that have a role in asthma pathogenesis. We also discuss the implications of current asthma therapeutics beyond symptom prevention.

Total unilateral pulmonary collapse secondary to allergic bronchopulmonary aspergillosis: a case series of an unusual cause of complete atelectasis. BMC Pulm Med 2021; 21:425. [PMID: 34952578 PMCID: PMC8709957 DOI: 10.1186/s12890-021-01789-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2021] [Accepted: 12/07/2021] [Indexed: 12/14/2022] Open
Abstract
Background Allergic bronchopulmonary aspergillosis (ABPA) is a bronchopulmonary disease caused by a complex hypersensitivity to Aspergillus and is usually associated with underlying respiratory diseases such as asthma or cystic fibrosis. Mucus plugging can lead to segmental or lobar atelectasis, but complete lung atelectasis has been exceptionally reported in the literature, making it difficult to diagnose. The diagnosis of ABPA may however be suggested in patients without known predisposing respiratory disorder, even in the absence of other relevant radiographic findings. Case presentation We report five cases of total unilateral lung collapse secondary to ABPA in 70–81-year-old women. Two of them had a past history of ABPA, while total unilateral lung collapse was the first sign of the disease in the other three patients, contributing to the initial misdiagnosis. Flexible bronchoscopy was initially performed to remove mucus plugs from the obstructed airways but was inefficient in four cases. Corticosteroid and/or antifungal treatment was needed. Conclusion ABPA can cause total unilateral lung collapse even in patients without known underlying chronic respiratory disease, making the diagnosis difficult. Flexible bronchoscopy should be considered when lung collapse is associated with respiratory distress but corticosteroids are the mainstay treatment for ABPA.

Abstract
BACKGROUND In allergic bronchopulmonary aspergillosis (ABPA), prolonged nebulised antifungal treatment may be a strategy for maintaining remission. METHODS We performed a randomised, single-blind, clinical trial in 30 centres. Patients with controlled ABPA after a 4-month attack treatment (corticosteroids and itraconazole) were randomly assigned to nebulised liposomal-amphotericin-B or placebo for 6 months. The primary outcome was occurrence of a first severe clinical exacerbation within 24 months following randomisation. Secondary outcomes included the median time-to-first severe clinical exacerbation, number of severe clinical exacerbations per patient, ABPA-related biological parameters. RESULTS Among 174 enrolled patients with ABPA from March 2015 through July 2017, 139 were controlled after 4-month attack treatment and were randomised. The primary outcome occurred in 33 (50.8%) of 65 patients in nebulised liposomal-amphotericin-B group and 38 (51.3%) of 74 in placebo group (absolute difference -0.6%, 95% CI -16.8% to +15.6%, odds ratio 0.98, 95% CI 0.50 to 1.90; p=0.95). The median time-to-first severe clinical exacerbation was longer in liposomal-amphotericin-B group, 337 days (IQR, 168 to 476) versus 177 (64 to 288). At the end of maintenance therapy, total immunoglobulin-E and Aspergillus precipitins were significantly decreased in nebulised liposomal-amphotericin-B group. CONCLUSIONS In ABPA, maintenance therapy using nebulised liposomal-amphotericin-B did not reduce the risk of severe clinical exacerbation. The presence of some positive secondary outcomes creates clinical equipoise for further research.

Abstract
BACKGROUND The prevalence and outcomes of allergic bronchopulmonary aspergillosis (ABPA) in the elderly remain unknown. METHODS We reviewed our database to identify the proportion of subjects diagnosed with ABPA at ≥60 years of age (ABPA-elderly). We compared the clinical features, treatment and outcomes of ABPA-elderly versus the non-elderly (ABPA diagnosed at <60 years of age). RESULTS Between 2007 and 2019, we encountered 810 ABPA subjects with a mean age of 34.9 years (49.4% women). Of these, 43 (5.3%) were aged ≥60 years (ABPA-elderly). There was a trend towards lower median (interquartile range [IQR]) serum total IgE (4900 [2659-10000] vs. 7156 [23360-11963] IU/mL; P = .06) and Aspergillus fumigatus-specific IgE (12.3 [4.8-29.6] vs. 22.4 [7.7-41.5] kUA/L; P = .06) in the elderly than the non-elderly. Eosinophil counts were similar in the two groups. The median [IQR] number of segments involved by bronchiectasis (5 [2-9] vs. 7 [4-11]) was significantly lower in the ABPA-elderly (P = .001). The proportion of subjects experiencing ABPA exacerbations was significantly (P = .047) lower in the elderly (25.6%) vs. the non-elderly (40.8%). There was also a tendency towards a lower mean number of exacerbations in the elderly (155 vs. 208 exacerbation per 1000 person-years) than the non-elderly (P = .09). There was also a trend towards longer mean time to first exacerbation in the ABPA-elderly than the non-elderly (1612 vs. 1159 days). CONCLUSION ABPA was uncommon in the elderly. The bronchiectasis is less extensive with a trend towards lower immunological severity and fewer exacerbations in the elderly than the non-elderly subjects with ABPA.

Abstract
Allergic bronchopulmonary aspergillosis is an allergic pulmonary condition caused by hypersensitivity to antigens of Aspergillus sp. found most commonly in patients with underlying asthma or cystic fibrosis. Host factors which alter the innate and adaptive immune responses to this abundant airborne fungus contribute to the development of chronic airway inflammation, bronchiectasis, and fibrosis. Traditionally, treatment has focussed on reducing fungal burden and immune response to fungal antigens. However, a significant proportion of patients continue to suffer recurrent exacerbations with progressive lung damage, and the side effect burden of existing treatments is high. New treatments including novel antifungal agents, monoclonal antibodies against aspects of the adaptive immune response as well as targeted immunotherapies may be better tolerated and achieve improved outcomes but have not yet been studied in large-scale randomised control trials.

Abstract
BACKGROUND Fungal sensitivity has been associated with severe asthma outcomes. However, the clinical implication of Aspergillus fumigatus sensitization in difficult-to-treat (or difficult) asthma is unclear. OBJECTIVES To characterize the clinical implications of A fumigatus sensitization in a large difficult asthma cohort. METHODS Participants who underwent both skin prick and specific IgE testing to A fumigatus (n = 318) from the longitudinal real-life Wessex AsThma CoHort of difficult asthma, United Kingdom, were characterized by A fumigatus sensitization (either positive skin prick test result or specific IgE) and allergic bronchopulmonary aspergillosis status using clinical/pathophysiological disease measures. RESULTS A fumigatus sensitization was found in 23.9% (76 of 318) of patients with difficult asthma. Compared with A fumigatus nonsensitized subjects, those with sensitization were significantly more often male (50% vs 31%), older (58 years) with longer asthma duration (33 years), higher maintenance oral corticosteroid (39.7%) and asthma biologic use (27.6%), raised current/maximum log10 total IgE+1 (2.43/2.72 IU/L), worse prebronchodilator airflow obstruction (FEV1 62.2% predicted, FEV1/forced vital capacity 61.2%, forced expiratory flow between 25% and 75% exhalation 30.9% predicted), and frequent radiological bronchiectasis (40%), but had less psychophysiologic comorbidities. Allergic bronchopulmonary aspergillosis diagnosis was associated with higher treatment needs and stronger eosinophilic signals. Factors independently associated with A fumigatus sensitization in difficult asthma included maintenance oral corticosteroid use (odds ratio [OR], 3.34) and maximum log10 total IgE+1 (OR, 4.30), whereas for allergic bronchopulmonary aspergillosis included maintenance oral corticosteroid use (OR, 6.98), maximum log10 total IgE+1 (OR, 4.65), and radiological bronchiectasis (OR, 4.08). CONCLUSIONS A fumigatus sensitization in difficult asthma identifies a more severe form of airways disease associated with greater morbidity, treatment need, and airways dysfunction/damage, but fewer psychophysiologic comorbidities. Screening of A fumigatus status should be an early element in the comprehensive assessment of patients with difficult asthma.

A randomised trial of prednisolone versus prednisolone and itraconazole in acute-stage allergic bronchopulmonary aspergillosis complicating asthma. Eur Respir J 2021; 59:13993003.01787-2021.

Abstract
Whether a combination of glucocorticoid and antifungal triazole is superior to glucocorticoid alone, in reducing exacerbations, in patients with allergic bronchopulmonary aspergillosis (ABPA) remains unknown. We aimed to compare the efficacy and safety of prednisolone-itraconazole combination versus prednisolone monotherapy in ABPA.We randomised subjects with treatment-naïve acute-stage ABPA complicating asthma to receive either prednisolone alone (four months) or a combination of prednisolone and itraconazole (four and six months, respectively). The primary outcomes were exacerbation rates at 12 months and glucocorticoid-dependent ABPA within 24 months of initiating treatment. The key secondary outcomes were response rates and percentage decline in serum total IgE at six weeks, time to first ABPA exacerbation, and treatment-emergent adverse effects (AE).We randomised 191 subjects to receive either prednisolone (n=94) or prednisolone-itraconazole combination (n=97). The one-year exacerbation rate was 33% and 20.6% in the prednisolone and the prednisolone-itraconazole arms, respectively (p=0.054). None of the participants progressed to glucocorticoid-dependent ABPA. All the subjects experienced a composite response at 6-weeks, along with a decline in serum total IgE (mean decline, 47.6% versus 45.5%). The mean time to first ABPA exacerbation (417 days) was not different between the groups. None of the participants required modification of therapy due to AE.There was a trend towards a decline in ABPA exacerbations at 1-year with the prednisolone-itraconazole combination than prednisolone monotherapy. A three-arm trial comparing itraconazole and prednisolone monotherapies with their combination, preferably in a multicentric design, is required to define the best treatment strategy for acute-stage ABPA.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction to Aspergillus species that aggravates bronchial asthma. Previous studies demonstrated the glucocorticoid-sparing effect of dupilumab in patients with ABPA. There is no report of complete withdrawal of glucocorticoids after dupilumab.
CASE SUMMARY The patient was a 54-year-old woman with bronchial asthma treated with inhaled corticosteroids and a long-acting beta-2 agonist. She consulted our institution for productive cough and fever in March 2017. Chest computed tomography scan revealed mucoid impaction, and the bronchial lavage fluid culture was positive for Aspergillus fumigatus. The diagnosis was ABPA. The patient was treated with oral glucocorticoids from April 2017 to November 2017. In January 2019, she had bronchial asthma exacerbation, and a chest computed tomography scan showed recurrent mucoid impaction. She was treated with oral glucocorticoids and itraconazole. In February 2020, during tapering of oral glucocorticoid, she had the third episode of bronchial asthma exacerbation and a mucoid impaction. The patient was treated with dupilumab in addition to oral glucocorticoid and itraconazole. The clinical response improved, and oral glucocorticoid was discontinued in June 2020.
CONCLUSION This is the first case of ABPA in which complete withdrawal of glucocorticoid was possible after treatment with dupilumab.

Abstract
Zimbabwe currently faces several healthcare challenges, most notably HIV and associated infections including tuberculosis (TB), malaria and recently outbreaks of cholera, typhoid fever and COVID-19. Fungal infections, which are also a major public health threat, receive considerably less attention. Consequently, there is dearth of data regarding the burden of fungal diseases in the country. We estimated the burden of fungal diseases in Zimbabwe based on published literature and 'at-risk' populations (HIV/AIDS patients, survivors of pulmonary TB, cancer, chronic obstructive pulmonary disease, asthma and patients receiving critical care) using previously described methods. Where there was no data for Zimbabwe, regional, or international data was used. Our study revealed that approximately 14.9% of Zimbabweans suffer from fungal infections annually, with 80% having tinea capitis. The annual incidence of cryptococcal meningitis and Pneumocystis jirovecii pneumonia in HIV/AIDS were estimated at 41/100,000 and 63/100,000, respectively. The estimated prevalence of recurrent vulvovaginal candidiasis (RVVC) was 2,739/100,000. The estimated burden of fungal diseases in Zimbabwe is high in comparison to other African countries, highlighting the urgent need for increased awareness and surveillance to improve diagnosis and management.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an immunological pulmonary disorder caused by hypersensitivity to Aspergillus which colonizes the airways of patients with asthma and cystic fibrosis. Its diagnosis could be difficult in some cases due to atypical presentations especially when there is no medical history of asthma. Treatment of ABPA is frequently associated to side effects but cumulated drug toxicity due to different molecules is rarely reported. An accurate choice among the different available molecules and effective on ABPA is crucial. We report a case of ABPA in a woman without a known history of asthma. She presented an acute bronchitis with wheezing dyspnea leading to an acute respiratory failure. She was hospitalized in the intensive care unit. The bronchoscopy revealed a complete obstruction of the left primary bronchus by a sticky greenish material. The culture of this material isolated Aspergillus fumigatus and that of bronchial aspiration fluid isolated Pseudomonas aeruginosa. The diagnosis of ABPA was based on elevated eosinophil count, the presence of specific IgE and IgG against Aspergillus fumigatus and left segmental collapse on chest computed tomography. The patient received an inhaled treatment for her asthma and a high dose of oral corticosteroids for ABPA. Her symptoms improved but during the decrease of corticosteroids, the patient presented a relapse. She received itraconazole in addition to corticosteroids. Four months later, she presented a drug-induced hepatitis due to itraconazole which was immediately stopped. During the monitoring of her asthma which was partially controlled, the patient presented an aseptic osteonecrosis of both femoral heads that required surgery. Nine months after itraconazole discontinuation, she presented a second relapse of her ABPA. She received voriconazole for nine months associated with a low dose of systemic corticosteroid therapy with an improvement of her symptoms. After discontinuation of antifungal treatment, there was no relapse for one year follow-up.

Abstract
A 25-year-old man, who was taking treatment for his poorly controlled asthma, presented with symptoms of cough with expectoration, gradually progressive shortness of breath, fever on and off and diffuse wheeze for 2 years. Chest X-ray revealed hyperinflation of lung field with dense opacification at right upper lobe. High-resolution CT chest showed bilateral patchy consolidation, central bronchiectasis and high-attenuation mucus (HAM) impaction. His blood absolute eosinophil count, total serum IgE level, Aspergillus fumigatus specific IgE and IgG level were 1910, 16760 kU/L, 59.8 kU/L and 147.41 kU/L, respectively. Diagnosis of allergic broncho pulmonary aspergillosis (ABPA) was established according to International Society for Human and Animal Mycology society guidelines. He was started on systemic steroids and doing well after 6 months of follow-up. Our case illustrates HAM, which is a rare but typical radiological feature of ABPA.
