Allergic bronchopulmonary aspergillosis successfully treated with mepolizumab: Case report and review of the literature

GEMA 5.3. Spanish Guideline on the Management of Asthma

The Spanish Guideline on the Management of Asthma, better known by its acronym in Spanish GEMA, has been available for more than 20 years. Twenty-one scientific societies or related groups both from Spain and internationally have participated in the preparation and development of the updated edition of GEMA, which in fact has been currently positioned as the reference guide on asthma in the Spanish language worldwide. Its objective is to prevent and improve the clinical situation of people with asthma by increasing the knowledge of healthcare professionals involved in their care. Its purpose is to convert scientific evidence into simple and easy-to-follow practical recommendations. Therefore, it is not a monograph that brings together all the scientific knowledge about the disease, but rather a brief document with the essentials, designed to be applied quickly in routine clinical practice. The guidelines are necessarily multidisciplinary, developed to be useful and an indispensable tool for physicians of different specialties, as well as nurses and pharmacists. Probably the most outstanding aspects of the guide are the recommendations to: establish the diagnosis of asthma using a sequential algorithm based on objective diagnostic tests; the follow-up of patients, preferably based on the strategy of achieving and maintaining control of the disease; treatment according to the level of severity of asthma, using six steps from least to greatest need of pharmaceutical drugs, and the treatment algorithm for the indication of biologics in patients with severe uncontrolled asthma based on phenotypes. And now, in addition to that, there is a novelty for easy use and follow-up through a computer application based on the chatbot-type conversational artificial intelligence (ia-GEMA).

Simultaneous diagnosis of allergic bronchopulmonary aspergillosis and Mycobacterium avium complex lung disease

Allergic bronchopulmonary aspergillosis (ABPA) and Mycobacterium avium complex lung disease (MAC-LD) often coexist because bronchiectasis, caused by ABPA or MAC, might be an important predisposing factor for both conditions. Here, we describe a man with asthma symptoms who had centrilobular small nodules and mucoid impaction on chest CT. We diagnosed the patient with simultaneous ABPA and MAC-LD on the basis of bronchoscopy findings. Itraconazole monotherapy led to substantial clinical improvement, avoiding the adverse effects of systemic corticosteroids. Sputum culture conversion of MAC was achieved after switching from itraconazole monotherapy to combination therapy comprising clarithromycin, rifampicin and ethambutol. ABPA recurred but was controlled by reinitiation of itraconazole. Overall, corticosteroid management was avoided for 38 months. Itraconazole monotherapy may be selected as initial treatment for ABPA with chronic infection, including MAC.

Mepolizumab in allergic bronchopulmonary aspergillosis complicated by infection

Allergic bronchopulmonary aspergillosis (ABPA) is an allergic reaction caused by the fungus Aspergillus, and it is often treated with steroids or antifungal agents. However, long-term use of these medications can lead to infections and drug interactions. We present the case of a 71-year-old woman with ABPA who was diagnosed with hepatitis B and active hepatitis C, and sputum analysis revealed the presence of bacteria. Oral steroids were initially administered, but the patient was switched to mepolizumab because of numerous infectious complications. The early introduction of mepolizumab is effective in patients with ABPA complicated by infectious diseases.

Do not forget asthma comorbidities in pediatric severe asthma!

Asthma is the most common chronic respiratory disease in childhood. The long-term goals in managing asthma aim to control symptoms and prevent exacerbations, as well as to reduce side effects of therapy and mortality disease-related. Most of patients have mild to moderate asthma and respond well to standard therapies. However, a minor proportion of children with asthma has severe disease that remains uncontrolled despite optimal adherence to prescribed therapy and treatment of contributory factors, including trigger exposures and comorbidities, which can mimic or worsen asthma and contribute to exacerbations and poor quality of life. Evaluation of comorbidities is fundamental to optimize the management of the disease in a subgroup of patients with poor responder asthma. The overall aim of this article is to describe characteristics of main pediatric severe asthma comorbidities reported in literature, giving clinicians tools to recognize and manage properly these conditions.

Mepolizumab and dupilumab as a replacement to systemic glucocorticoids for the treatment of Chronic Eosinophilic Pneumonia and Allergic Bronchopulmonary Aspergillosis - Case series, Almoosa specialist hospital

In this case series, we present four patients who had asthma and blood eosinophilia. Two patients were diagnosed with Chronic Eosinophilic Pneumonia (CEP) and the other two with Allergic Bronchopulmonary Aspergillosis (ABPA). Laboratory findings revealed profound peripheral eosinophilia with abnormal chest radiography (alveolar shadows, segmental atelectasis, and cystic changes). Initial improvement (clinical, laboratory, and radiological) occurred with traditional asthma therapy, including systemic corticosteroids. The patients did not tolerate corticosteroid therapy because of weight gain, uncontrolled diabetes, bone fractures, and psychological adverse effects. Mepolizumab (administered to two CEP cases and one ABPA case) and Dupilumab (administered to one ABPA case) were initiated as steroid-sparing agents, resulting in successful therapy without relapse or adverse effects. Mepolizumab, and Interleukin-5 (IL-5) antagonist, targets diseases mediated by eosinophil activity and proliferation. Dupilumab blocks the Interleukin-4/Interleukin-13 pathway and suppresses Type 2 inflammation, including Immunoglobulin E (IgE). Dupilumab resulted in up to 70% drop in total IgE levels from baseline and reduced eosinophil-mediated lung inflammation, despite the presence of normal or increased blood eosinophil counts.

Beyond the Guidelines: Treatment of Allergic Bronchopulmonary Aspergillosis in Cystic Fibrosis

OBJECTIVE

To review the available literature addressing alternative allergic bronchopulmonary aspergillosis (ABPA) treatment options for patients with cystic fibrosis (CF).

DATA SOURCES

A literature search of PubMed was performed (January 2002 to April 2021) using the following search terms: allergic bronchopulmonary aspergillosis, aspergillus-related lung disease, cystic fibrosis. Manufacturer prescribing information, clinical practice guidelines, and data from ClinicalTrials.gov were incorporated in the reviewed data.

STUDY SELECTION AND DATA EXTRACTION

Relevant English-language studies or those conducted in humans were considered for inclusion.

DATA SYNTHESIS

Available literature for alternative ABPA treatments in CF is lacking randomized controlled trials, but there is considerable support in case reports and case series describing the benefits in pediatric and adult patients. Recent literature has begun to explore the place in therapy for novel, corticosteroid-sparing treatment approaches. The alternative therapies summarized in this review all resulted in clinical improvement and subsequent discontinuation or dose reductions of oral corticosteroids, with minimal reported adverse drug effects.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

Although corticosteroids are the cornerstone of ABPA management, the toxicities can be significant limitations in an already high-risk patient population. Patients may fail or become intolerant to guideline-recommended therapies and require alternative treatment approaches.

CONCLUSIONS

Alternative treatment modalities for ABPA in patients with CF, including azole antifungals, pulsed intravenous glucocorticoids, omalizumab, mepolizumab, and inhaled amphotericin, appear to be efficacious and well tolerated. Pharmacological properties including route of administration, storage and stability, beyond use dating, and adverse effects of the various treatment modalities must be considered when selecting a practical care plan for patients.

The immune response to airway mycosis

The allergic airway diseases chronic rhinosinusitis (CRS), allergic fungal rhinosinusitis (AFRS), asthma, allergic bronchopulmonary mycosis/aspergillosis (ABPM/A), and cystic fibrosis (CF) share a common immunological signature marked by T_H2 and T_H17 cell predominant immune responses, the production of IgE antibody, and a typical inflammatory cell infiltrate that includes eosinophils and other innate immune effector cells. Severe forms of these disorders have long been recognized as being related to hypersensitivity reactions to environmental fungi. Increasingly however,environmental fungi are assuming a more primary role in the etiology of these disorders, with airway mycosis, a type of non-invasive airway fungal infection, recognized as an essential driving factor in at least severe subsets of allergic airway diseases. In this review, we consider recent progress made in understanding the immune mechanisms that drive airway mycosis-related diseases, improvements in immune-based diagnostic strategies, and therapeutic approaches that target key immune pathways.

Successful Treatment with Benralizumab for Allergic Bronchopulmonary Aspergillosis That Developed after Disastrous Heavy Rainfall in Western Japan

We herein report a 56-year-old woman who developed allergic bronchopulmonary aspergillosis (ABPA) possibly due to fungal exposure after disastrous heavy rainfall in Western Japan in 2018. She was diagnosed with ABPA complicated with asthma, increased peripheral blood eosinophil count, elevation of specific immunoglobulin E for Aspergillus fumigatus, positive Aspergillus fumigatus precipitation antibody reaction test results, and notable chest computed tomography findings. After treatment with benralizumab, her symptoms, peripheral blood eosinophil count, radiological findings, and respiratory function dramatically improved. The administration of benralizumab appears to be an effective treatment strategy for ABPA.

Successful treatment with mepolizumab for allergic bronchopulmonary mycosis complicated with bilateral septic arthritis of the knee joints caused by Methicillin-resistant Staphylococcus aureus

We report the case of a 50-year-old man with allergic bronchopulmonary mycosis (ABPM) complicated with bilateral septic arthritis of the knees caused by Methicillin-resistant Staphylococcus aureus (MRSA). He had a background of bronchial asthma and end-stage renal failure on maintenance dialysis. He was treated with 30 mg/day of prednisolone for 14 days for ABPM. He developed bilateral septic arthritis of the knees, caused by MRSA during prednisolone treatment. He underwent bilateral arthroscopic washout with a 2-week course of intra-articular arbekacin, concomitantly treated with a 6-week course of intravenous teicoplanin and oral rifampicin, subsequently followed by oral linezolid treatment. However, he suffered exacerbation of ABPM during treatment of septic arthritis. Because of these serious infectious complications, he was treated with mepolizumab instead of corticosteroids for the ABPM, which resolved all symptoms and clinical features. This case highlights mepolizumab treatment as an alternative to corticosteroid therapy for treatment of ABPM in patients with comorbidities such as infection.

Mepolizumab as Possible Treatment for Allergic Bronchopulmonary Aspergillosis: A Review of Eight Cases

Allergic bronchopulmonary aspergillosis (ABPA) is an eosinophilic pulmonary disorder caused by a hypersensitivity reaction to Aspergillus fumigatus that manifests with uncontrolled asthma, peripheral blood eosinophilia, and radiological findings, such as mucus plugging. Early diagnosis and proper treatment of ABPA are essential to prevent irreversible lung damage such as pulmonary fibrosis and bronchiectasis and improve the quality of life of patients. Beside inhaled medication for asthma, anti-inflammatory agents (i.e., systemic glucocorticoids) and antifungal agents are the mainstay treatment of ABPA. The goal of therapy using glucocorticoids and antifungal agents is to suppress the immune hyperreactivity to A. fumigatus and attenuate the fungal burden. Since the systemic glucocorticoid therapy may lead to serious adverse effects including osteoporosis, avascular necrosis, myopathy, cushingoid appearance, hypertension, insomnia, and increased risk of infection, a glucocorticoid-sparing agent could be considered. Mepolizumab is a humanized monoclonal antibody that binds to interleukin-5, which is the key mediator for eosinophil differentiation, activation, migration, and survival. We review eight cases of ABPA treated successfully with mepolizumab. Treatment with mepolizumab was not restricted to the total immunoglobulin E level, the limiting factor for omalizumab in ABPA. In addition, mepolizumab therapy improved forced expiratory volume in one second, radiological findings, and patient quality of life.

Use of monoclonal antibodies for allergic bronchopulmonary aspergillosis in patients with asthma and cystic fibrosis: literature review

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity reaction (HR) mediated by antigens to Aspergillus fumigatus. It is estimated that 2-15% of patients with cystic fibrosis (CF) and between 1% and 5% of asthmatics develop ABPA, affecting approximately 4.8 million people worldwide. The goals of treatment are controlling inflammation, reducing the number of exacerbations and limiting the progression of lung damage. Systemic steroids are therefore used as the mainstay therapy, along with antifungal medications. However, many patients do not respond or develop side effects to treatment. In this scenario, biological drugs such as Omalizumab, Mepolizumab, Benralizumab and Dupilumab have been implemented in clinical practice, even though there is a lack of scientific evidence to support their use. We performed a literature review of the studies carried out which analyzed biologics for the management of ABPA in adult populations with asthma and CF. To our knowledge this is the first literature review that included all biologics. We included a total of 32 studies, all but one were descriptive studies, and the vast majority evaluated the use of Omalizumab. Biologics appeared to have more benefit for patients with ABPA and asthma than CF, specifically at decreasing the frequency of acute exacerbations and by having a steroid-sparing effect. Although a decrease in serum IgE level is considered a measure of therapy success, values may not decline as expected in the context of a significant clinical improvement, highlighting the importance of measuring patient-oriented outcomes. As evidence comes mainly from case series and case reports, randomized controlled trials are needed to evaluate further the safety and efficacy of biologics in ABPA.The reviews of this paper are available via the supplemental material section.

Targeting eosinophils: severe asthma and beyond

Recent research in the field of bronchial asthma has mainly focused on eosinophilic disease phenotype. Several trials proved the efficacy and safety profile of eosinophils and interleukin (IL)-5 targeting molecules, currently approved for severe asthma and available on the market. They include mepolizumab and reslizumab, IL-5 blocking molecules, and benralizumab, targeting the IL-5 receptor and eliciting a NK cell-mediated antibody-dependent cellular cytotoxicity against eosinophils. Eosinophilic inflammation represents the common pathophysiological background of several conditions, providing the rationale for the use of the same biologics beyond asthma. Although with different evidence grade, from clinical trials to case reports, anti-IL-5 biologics have been investigated in eosinophilic granulomatosis with polyangitis, allergic bronchopulmonary aspergillosis, chronic eosinophilic pneumonia, nasal polyposis, hypereosinophilic syndrome, and eosinophilic esophagitis. However, non-negligible differences between asthma and other eosinophilic diseases, particularly in eosinophils homing (blood and/or tissues), target organs and thus clinical features, probably account for the different response to the same drug in different clinical conditions and highlights the need for tailoring the therapeutic approach by modulating the drug dose and/or by combination therapy with multiple drugs. The optimal safety and tolerability profile of anti-IL-5 drugs warrants further and larger experimental and real-life investigations, which are needed especially in the field of non-asthma eosinophilic diseases. This review aims at summarizing the rationale for the use of biologics in eosinophilic diseases and their mechanisms of action. The current efficacy and safety evidence about eosinophils and IL-5 targeting molecules in asthma and in eosinophilic conditions beyond bronchi is also discussed.

Successful treatment with mepolizumab in a case of allergic bronchopulmonary aspergillosis complicated with nontuberculous mycobacterial infection

Allergic bronchopulmonary aspergillosis (ABPA) is a complex hypersensitivity reaction that is associated with an allergic immunological response to Aspergillus species via Th2-related inflammation. The long-term use of a systemic corticosteroid is often needed for the treatment of ABPA. However, systemic corticosteroid treatment imposes a risk of the onset of a nontuberculous mycobacterial infection. Here we report the case of a patient with ABPA who required the long-term use of an oral corticosteroid because her repeated asthmatic attacks were successfully treated with mepolizumab, an anti-interleukin-5 monoclonal antibody. The patient, a 60-year-old Japanese female, had been treated with an oral corticoid and itraconazole. Despite the success of the initial treatment for ABPA, it was difficult to discontinue the use of the oral corticosteroid. In addition, Mycobacterium avium was detected from her bronchial lavage. We initiated mepolizumab treatment to taper the amount of corticosteroid and control the asthma condition. The patient's number of blood eosinophils, serum IgE level, fractional exhaled nitric oxide level, dosage of oral prednisolone, and need for inhaled budesonide/formoterol all improved, without an exacerbation of her asthma attacks. Although further research regarding mepolizumab treatment is needed, we believe that mepolizumab could be considered one of the agents for treating refractory ABPA.
