Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction to colonisation of the lungs with the fungus Aspergillus fumigatus, and affects around 10% of people with cystic fibrosis. ABPA is associated with an accelerated decline in lung function. High doses of corticosteroids are the main treatment for ABPA; although the long-term benefits are not clear, and their many side effects are well-documented. A group of compounds, the azoles, have activity against A fumigatus, and have been proposed as an alternative treatment for ABPA. Of this group, itraconazole is the most active. A separate antifungal compound, amphotericin B, has been used in aerosolised form to treat invasive infection with A fumigatus, and may have potential for the treatment of ABPA. Antifungal therapy for ABPA in cystic fibrosis needs to be evaluated. This is an update of a previously published review. OBJECTIVES The review aimed to test the hypotheses that antifungal interventions for the treatment of ABPA in cystic fibrosis: 1. improve clinical status compared to placebo or standard therapy (no placebo); and 2. do not have unacceptable adverse effects. If benefit was demonstrated, we planned to assess the optimal type, duration, and dose of antifungal therapy. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register, which comprises references identified from comprehensive electronic database searches, handsearches of relevant journals, and abstract books of conference proceedings. Date of the most recent search of the Group's Trials Register was 28 September 2021. We searched ongoing trials registries, most recently on 11 March 2022. Earlier, we also approached pharmaceutical companies regarding possible unpublished trials. SELECTION CRITERIA Published or unpublished randomised controlled trials, in which antifungal treatments were compared to either placebo or no treatment, or where different doses of the same treatment were used in the treatment of ABPA in people with cystic fibrosis. DATA COLLECTION AND ANALYSIS The searches identified six trials; none of which met the inclusion criteria for the review. MAIN RESULTS We included no completed randomised controlled trials. There is currently one ongoing trial, which we may find eligible for a future update. AUTHORS' CONCLUSIONS At present, there are no randomised controlled trials that evaluate the use of antifungal therapies for the treatment of ABPA in people with cystic fibrosis, although one trial is currently ongoing. Trials with clear outcome measures are needed to properly evaluate the use of corticosteroids in people with ABPA and cystic fibrosis.

Abstract
INTRODUCTION Allergic bronchopulmonary aspergillosis (ABPA) is a complex disease, triggered by a hypersensitivity reaction to the allergens of Aspergillus fumigatus, a fungus that opportunistically colonizes the lungs of patients with asthma. The diagnosis of ABPA is difficult. A major problem is the lack of standardized allergens used in the determination of specific IgE, but the use of recombinant allergens has been proposed to overcome this. The aim of the present study is to evaluate whether serological tests for IgE specific to recombinant allergens of A. fumigatus (rAsp) can aid in the detection of sensitization to this fungus and in the diagnosis of ABPA. METHODS This was an observational, cross-sectional study. The diagnosis of ABPA, using classical criteria, was searched in 65 asthmatics patients with immediate cutaneous reactivity to A. fumigatus. After that, serum titers of IgE against rAsp f 1, rAsp f 2, rAsp f 3, rAsp f 4 and rAsp f 6 were determined. In order to compare the differences between patients with confirmed and excluded diagnosis of ABPA, the two-tailed Fisher's exact test was used. RESULTS Although 19 of 65 patients had IgE against at least one recombinant, the disease was diagnosed in only six patients by classical criteria. One of them had IgE against all recombinant allergens tested and another one had antibody against Asp f 3. DISCUSSION The determination of serum IgE against recombinant A. fumigatus allergens in this group was not helpful to make the diagnosis of ABPA, neither to detect sensitization to fungus.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an uncommon condition which may complicate asthma and cystic fibrosis; it is seldom considered life-threatening. We report a well 8-year-old boy with cystic fibrosis and normal lung function who progressed to respiratory failure over several days, attributable to ABPA. He recovered with non-invasive ventilation and oral corticosteroid and antifungal medications, regaining normal lung function within 2 months. To our knowledge, such an acute severe presentation of ABPA in a previously well child has not been reported before.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) is a complex condition that affects people with asthma and cystic fibrosis (CF). It results from exposure to the fungus Aspergillus fumigatus, which leads to worsening airway inflammation and progressive damage to the lungs. The aim of this review is to outline the pathogenesis of the disorder, diagnostic criteria and to discuss the use of anti-fungal agents in its treatment. METHODS The Cochrane library of systematic reviews and the Cochrane database of controlled trials were searched for controlled trials on ABPA and its treatment in both asthma and CF. In addition, articles included within the reviews were examined separately, and a separate search carried out using Medline. RESULTS A systematic review for the use of azole anti-fungal agents in ABPA was identified for their use in both CF and non-CF-related disease. The review of ABPA alone identified two randomized-controlled trials of itraconazole in chronic disease. These trials demonstrated improvements in symptoms and immune activation, but were short-term trials and failed to show a significant change in lung function. No trials were identified in CF. CONCLUSIONS The use of anti-fungal agents in ABPA seems to be a rational one, with short-term efficacy demonstrated for the use of itraconazole. Further investigations are required to identify individuals who will benefit most from treatment and to establish the correct dose and means of delivering treatment in ABPA. Longer-term studies are required to demonstrate that treatment modifies the progressive decline in lung function seen with the disease.

Abstract
BACKGROUND Allergic bronchopulmonary aspergillosis (ABPA) complicates chronic asthma and results from hypersensitivity to the fungus Aspergillus fumigatu s, causing an intense systemic immune response and progressive lung damage. OBJECTIVE We sought to determine whether treatment with the antifungal agent itraconazole reduced eosinophilic airway inflammation in subjects with ABPA. METHODS A randomized, double-blind, placebo-controlled trial was performed in stable subjects with ABPA (n = 29). Subjects received 400 mg of itraconazole per day (n = 15) or placebo (n = 14) for 16 weeks. All subjects were reviewed monthly with history, spirometry, and sputum induction to measure airway inflammation, serum total IgE and IgG levels to A fumigatu s, and blood eosinophil counts. RESULTS By using regression analysis in a random-effects model, subjects receiving itraconazole had a decrease in sputum eosinophils of 35% per week, with no decrease seen in the placebo arm (P <.01). Sputum eosinophil cationic protein levels decreased with itraconazole treatment by 42% per week compared with 23% in the placebo group (P <.01). Itraconazole reduced systemic immune activation, leading to a decrease in serum IgE levels (310 IU/mL) compared with levels seen in the placebo group (increase of 18 IU/mL, P <.01) and a decrease in IgG levels to A fumigatu s (15.4 IU/mL) compared with levels seen in the placebo group (increase of 3.7 IU/mL, P =.03). There were fewer exacerbations requiring oral cortico-steroids in those treated with itraconazole compared with in the placebo group (P =.03). CONCLUSION Itraconazole treatment of subjects with stable ABPA reduces eosinophilic airway inflammation, systemic immune activation, and exacerbations. These results imply that itraconazole is a potential adjunctive treatment for ABPA.

Abstract
Aspergillus is a ubiquitous fungus that causes a variety of clinical syndromes in the lung, ranging from aspergilloma in patients with lung cavities, to chronic necrotizing aspergillosis in those who are mildly immunocompromised or have chronic lung disease. Invasive pulmonary aspergillosis (IPA) is a severe and commonly fatal disease that is seen in immunocompromised patients, while allergic bronchopulmonary aspergillosis is a hypersensitivity reaction to Aspergillus antigens that mainly affects patients with asthma. In light of the increasing risk factors leading to IPA, such as organ transplantation and immunosuppressive therapy, and recent advances in the diagnosis and treatment of Aspergillus-related lung diseases, it is essential for clinicians to be familiar with the clinical presentation, diagnostic methods, and approach to management of the spectrum of pulmonary aspergillosis.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is a condition that results from a hypersensitivity reaction to the fungus Aspergillus fumigatus. The purpose of the present review is to examine the pathogenesis of this condition and the evidence for treatments available. Allergic bronchopulmonary aspergillosis is characterized by an intense airway inflammation with eosinophils and the formation of mucus plugs. Clinically, there are periods of exacerbation and remission that may lead to proximal bronchiectasis and fibrotic lung disease. New evidence confirms the role of intense airway inflammation with eosinophils, but also suggests a role for interleukin (IL)-8/neutrophil-mediated inflammation in this process, and the potential deficiency of anti-inflammatory cytokines such as reduced IL-10. Treatment for ABPA has so far focused on corticosteroids to suppress eosinophilic airway inflammation. An expanding knowledge of the pathology of ABPA also suggests other therapies may be of potential benefit, particularly the use of azole antifungal agents. Allergic bronchopulmonary aspergillosis is itself an important complication of asthma and cystic fibrosis. A greater understanding of the condition is required to improve management and well-designed clinical trials need to be carried out to critically assess new and current treatments. In addition, the information gained from the studies of its pathogenesis has the potential to benefit our understanding of the disease processes in asthma and bronchiectasis.

Abstract
We report a case of allergic bronchopulmonary disease caused by Bipolaris hawaiisensis in an immunocompetent host, presenting with symptoms and radiographic findings suggestive of necrotizing pneumonia. Cultures of the plugs and bronchial washing yielded the pathogenic fungi. Laboratory tests revealed eosinophilia and elevation of serum IgE. This patient was successfully treated with steroids, amphotericin B lipid complex, and itraconazole. Review of 10 previously reported cases and their clinical manifestations and treatment are presented.

Abstract
Allergic fungal rhinosinusitis (AFRS) is believed to have a cause similar to allergic bronchopulmonary aspergillosis (ABPA). Both are thought to be mediated by both type I (IgE) and type III (IgE-antigen immune complexes) Gell and Coombs reactions. ABPA patients also exhibit unique characteristics, such as HLA-DR2 or HLA-DR5 genotypes, and elevated suppressor T cell activity. While the pathophysiology of AFRS is similar histopathologically, similar immunologic studies have not been as well documented. Most cases of AFRS involve dematiaceous fungi, rather than Aspergillus. A suggested laboratory work-up for the disease is presented.

Abstract
BACKGROUND Allergic Bronchopulmonary Aspergillosis (ABPA) is an allergic reaction to colonisation of the lungs with the fungus Aspergillus fumigatus and affects around 10% people with cystic fibrosis. ABPA is associated with an accelerated decline in lung function. Corticosteroids, in high doses, are the main treatment for ABPA although the long-term benefits are not clear and their many side effects are well documented. A group of compounds, the azoles, have activity against Aspergillus fumigatus and have been proposed as an alternative treatment for ABPA. Of this group, Itraconazole is the most active. A separate antifungal compound, Amphotericin B has been employed in aerosolised form to treat invasive infection with Aspergillus fumigatus, and may have potential for the treatment of ABPA. Antifungal therapy for ABPA in cystic fibrosis needs to be evaluated. OBJECTIVES The review tested the hypotheses that antifungal interventions for the treatment of ABPA in cystic fibrosis: 1. improve clinical status compared to placebo or standard therapy (no placebo); 2. do not have unacceptable adverse effects. If benefit was demonstrated, the optimal type, duration and dose of antifungal therapy was assessed. SEARCH STRATEGY We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group specialist trials register which comprises references identified from comprehensive electronic database searches, handsearching relevant journals and handsearching abstract books of conference proceedings. In addition, pharmaceutical companies were approached. SELECTION CRITERIA Randomised controlled trials, published or unpublished, where antifungal treatments have been compared to either placebo or no treatment, or where different doses of the same treatment have been used in the treatment of ABPA in patients with cystic fibrosis. DATA COLLECTION AND ANALYSIS No completed randomised controlled trials were identified. MAIN RESULTS No completed randomised controlled trials were identified. REVIEWER'S CONCLUSIONS At present, there are no randomised controlled trials to evaluate the use of antifungal therapies for the treatment of ABPA in people with cystic fibrosis. Trials with clear outcome measures are needed to properly evaluate this potentially useful treatment for cystic fibrosis.

Abstract
Because of the common nature of asthma and the attention this disease has been given in recent years, it is important to consider the possibility of other disorders that may present in a similar manner to asthma. Failure to consider alternative diagnoses often leads to inappropriate treatment with medications such as systemic corticosteroids that result in untoward morbidity. This review will discuss several diseases originating not only in the tracheobronchial tree but also in extrapulmonary sites, such as the gastrointestinal tract, that may be mistakenly diagnosed as asthma. Newly described entities such as irritant vocal cord dysfunction and exercise-induced hyperventilation syndrome are discussed in this article, as is new information pertaining to well-established diseases such as Churg-Strauss syndrome and sarcoidosis.
