Allergic bronchopulmonary aspergillosis

Ritesh Agarwal, Inderpaul S Sehgal, Sahajal Dhooria, Ashutosh N Aggarwal
Allergic bronchopulmonary aspergillosis (ABPA) is a complex pulmonary disorder characterized by recurrent episodes of wheezing, fleeting pulmonary opacities and bronchiectasis. It is the most prevalent of the Aspergillus disorders with an estimated five million cases worldwide. Despite six decades of research, the pathogenesis, diagnosis and treatment of this condition remains controversial. The International Society for Human and Animal Mycology has formed a working group to resolve the controversies around this entity...

We describe an interesting case of severe asthma who was not showing satisfactory response to standard treatment. Investigations revealed him to be suffering from allergic bronchopulmonary aspergillosis (ABPA). After starting systemic steroids he showed marked improvement initially only to have recurrent symptoms within a year. He was investigated further and found to have chronic pulmonary aspergillosis in the form of chronic cavitary pulmonary aspergillosis (CCPA) and aspergilloma as also the presence of selective IgA deficiency...

Allergic bronchopulmonary aspergillosis (ABPA) affects up to 15% of patients with cystic fibrosis (CF). Corticosteroids are used as first-line therapy, but relapse and adverse effects commonly occur. Case reports have suggested the efficacy of the anti-IgE recombinant humanized monoclonal antibody omalizumab. A retrospective multicenter observational French study retrieved 32 CF patients (11 children and 21 adults) who have received omalizumab for more than 3 months in the context of ABPA. Clinical characteristics, concomitant medications (inhaled and oral corticosteroids, antifungal drugs), lung function, body mass index (BMI), and serum IgE were compared at the start and during the first year of omalizumab therapy...

BACKGROUND: In patients with asthma, the fungus Aspergillus fumigatus can cause allergic bronchopulmonary aspergillosis (ABPA). Familial ABPA is reported, and some genetic factors have been associated with the disease, however, these are small studies (n ≤ 38) and do not explain all cases of ABPA. METHODS: We analysed SNPs in 95 ABPA patients, comparing frequencies to 152 atopic asthmatic and 279 healthy controls. Twenty two genes were selected from literature, and 195 tagging SNPs were analysed for genetic association with ABPA using logistic regression corrected for multiple testing...

Aspergillus fumigatus is the main fungus cultured in the airways of patients with cystic fibrosis (CF). Allergic bronchopulmonary aspergillosis occurs in ~10% of CF patients and is clearly associated with airway damage and lung function decline. The effects of A. fumigatus colonization in the absence of allergic bronchopulmonary aspergillosis are less well established. Retrospective clinical studies found associations of A. fumigatus-positive cultures with computed tomography scan abnormalities, greater risk of CF exacerbations and hospitalizations, and/or lung function decline...

Aspergillus flavus is an ubiquitous, opportunistic fungus responsible to cause invasive fungal allergic diseases, including bronchopulmonary invasive aspergillosis in persons with altered immune function. Lectins have been implicated as interaction mediators between the pathogenic fungi and human host. We isolated L-fucose specific lectin from A. flavus (FFL) and purified it to homogeneity with a combination of ion exchange and hydrophobic interaction chromatography methods. Its hemagglutination activity was significantly inhibited by 125 μM L-fucose as compared to other sugars and sugar derivatives...

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction to Aspergillus that mainly affects patients with asthma. For diagnosis, elevated serum IgE level are needed according to Greenberger and Patterson criteria. We report a case of 43 years-old woman who developed ABPA with productive cough, fever and radiological findings of multiple confluent areas of consolidation in both upper lobes. Laboratory tests showed elevated peripheral eosinophil counts (9.3 x 10(3)/ml). In bronchial washing A...

Aspergillus fumigatus can cause several allergic disorders including Aspergillus-sensitized asthma, allergic bronchopulmonary aspergillosis (ABPA), and allergic fungal rhinosinusitis (AFRS). ABPA is an immunological pulmonary disorder caused by allergic reactions mounted against antigens of A. fumigatus colonizing the airways of patients with asthma (and cystic fibrosis). Allergic bronchopulmonary mycosis is an allergic fungal airway disease caused by thermotolerant fungi other than A. fumigatus On the other hand, AFRS is a type of chronic rhinosinusitis that is also a result of hypersensitivity reactions to the presence of fungi that become resident in the sinuses...

Allergic bronchopulmonary aspergillosis (ABPA) is an immunological lung disorder occurring due to hypersensitivity to fungus Aspergillus fumigatus. Early diagnosis of ABPA is desirable before the disease leads to irreversible damage and end stage lung disease. Diagnosis of ABPA is based upon a set of clinical, serological and radiological criteria. Radiology plays an important role not only in diagnosis but also in prognostication of the disease. However, a radiologist should also be familiar with the clinical spectrum and laboratory findings of the disease...

INTRODUCTION: Kenya is a developing country with a high rate of tuberculosis (TB) and a moderate HIV infection burden. No estimate of the burden of fungal diseases in Kenya is published. METHODOLOGY: We used specific populations at risk and fungal infection frequencies from the literature to estimate national incidence or prevalence of serious fungal infections. Used sources were: 2010 WHO TB statistics, Kenya Acquired Immunodeficiency Syndrome (AIDS) Epidemic Update 2012, Kenya Facts and figures 2012, Kenya Demographic and Health Survey 2008-2009...

Broncholithiasis is an often overlooked condition and has been associated with symptoms such as cough, hemoptysis, and recurrent respiratory infections. The most common mechanism of a broncholith formation is the enlargement and subsequent erosion of a lymph node into an adjacent airway. Here, we describe this entity in a patient with advanced allergic bronchopulmonary aspergillosis, with chronic hypercapnic respiratory failure, and with frequent infective exacerbations. These frequent exacerbations were initially attributed to the poor lung function of the patient and the inability to cough out the secretions...

Allergic asthma refers to a chronic reversible bronchoconstriction influenced by an allergic trigger, leading to symptoms of cough, wheezing, shortness of breath, and chest tightness. Allergic bronchopulmonary aspergillosis is a complex hypersensitivity reaction, often in patients with asthma or cystic fibrosis, occurring when bronchi become colonized by Aspergillus species. The clinical picture is dominated by asthma complicated by recurrent episodes of bronchial obstruction, fever, malaise, mucus production, and peripheral blood eosinophilia...

BACKGROUND: Microbiological diagnosis of aspergillosis and triazole resistance is limited by poor culture yield. To better estimate this shortcoming, we compared culture and molecular detection of A. fumigatus in respiratory samples from French patients at risk for aspergillosis. METHODS: A total of 97 respiratory samples including bronchoalveolar lavages (BAL), bronchial aspirates (BA), tracheal aspirates, sputa, pleural fluids, and lung biopsy were collected from 33 patients having invasive aspergillosis (n = 12), chronic pulmonary aspergillosis (n = 3), allergic bronchopulmonary aspergillosis (n = 7), or colonization (n = 11) and 28 controls...

Few studies have evaluated the utility of Aspergillus fumigatus-specific IgG in allergic bronchopulmonary aspergillosis (ABPA). Herein, we evaluate the role of specific IgG in diagnosis and monitoring treatment response in ABPA. Forty-eight control subjects with A. fumigatus-associated asthma underwent A. fumigatus-specific IgG measurements at baseline, while specific IgG was assayed in 102 treatment-naïve subjects of ABPA at baseline, after eight weeks of glucocorticoid therapy, and during exacerbations...

Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disease with small prevalence. Exposure to aspergillus mold causes immunologic hypersensitivity and may cause ranges of symptoms from minimal to detrimental outcomes. Diagnosing and treating the disease before the development of bronchiectasis may save the patient from poor outcomes. This report presents a case of recurrent ABPA without any symptom of asthma, which impeded the correct diagnosis even after numerous hospitalizations.

Allergic Bronchopulmonary Aspergillosis (ABPA) can be diagnosed in an asthmatic with suitable radiologic and immunological features. However ABPA is likely to be misdiagnosed with bacterial pneumonia. Here we report a case of ABPA masquerading as recurrent bacterial pneumonia. Treatment with high-dose inhaled corticosteroids was effective. To our best knowledge, this is the first reported case of ABPA in Vietnam.

Although mucus is a normal product of the tracheobronchial tree, some diseases of the respiratory tract are characterized by unusually thick (inspissated) forms of mucus that accumulate within the airways. These are known as mucus plugs. The pathologic composition of these plugs is surprisingly diverse and, in many cases, correlates with distinctive clinical, radiologic, and bronchoscopic findings. The best-known conditions that involve mucus plugs are allergic bronchopulmonary aspergillosis, plastic bronchitis, and asthma...

Allergic bronchopulmonary aspergillosis (ABPA) results from a hypersensitivity response to airways colonization with Aspergillus fumigatus, and it occurs most often in individuals with asthma or cystic fibrosis. Allergic bronchopulmonary aspergillosis is an indolent, but potentially progressive, disease in patients. In patients infected with human immunodeficiency virus (HIV), ABPA is rare, and its description in the literature is limited to case reports. We describe the occurrence of ABPA in a 37-year-old woman with well controlled HIV infection...
