Allergic bronchopulmonary aspergillosis (ABPA) is mediated by hypersensitivity reactions to Aspergillus fumigatus, which is ubiquitous in the environment. People with Cystic Fibrosis (PwCF) are at an increased risk for developing ABPA, which can lead to frequent pulmonary exacerbations and progressive decline in lung function. In the age of highly effective modulator therapies (HEMT), PwCF have improved clinical outcomes and overall life expectancy, but they continue to suffer from comorbidities such as ABPA, which may be difficult to diagnose and treat. Establishing the diagnosis of ABPA in PwCF requires high clinical suspicion due to similarities in symptoms with the underlying disease. First-line treatment involves corticosteroids and anti-fungals, which have multiple side effects and drug interactions, especially with HEMT. Given this challenge, biologics have gained attention as potential agents directly targeting the Th-2 inflammatory pathway of ABPA with good tolerability and without significant drug interactions with HEMT. In this review, we discuss the diagnostic process and management of ABPA in PwCF, including a brief overview of the current literature on biologic agents.

Background: The incidence of iatrogenic pneumothorax (IPTX) following transbronchial lung cryobiopsy (TBLCB) ranges from 1.4% to 20.2%. While chest X-ray (CXR) is the standard imaging modality to exclude IPTX, thoracic ultrasound (TUS) has demonstrated superior accuracy in detecting pneumothorax across various contexts. This study evaluates TUS as a reliable alternative to routine CXR for ruling out IPTX after TBLCB. Methods: A retrospective observational study included 51 patients undergoing ambulatory TBLCB. Pre- and post-TBLCB TUS were performed. CXR was reserved for cases where TUS findings were inconclusive (absence of sliding lung [SL] and seashore sign [SS] in any lung zones) or if patients exhibited symptoms or signs of IPTX. Results: TUS findings were concordant in 44 (86.1%) patients, of whom 42 (95.5%) did not require CXR. Two patients (4.5%) with symptomatic IPTX were identified and managed. Among the seven patients (13.7%) requiring CXR due to inconclusive TUS or symptoms, five (71.4%) were negative for IPTX, and two (28.6%) had asymptomatic IPTX. Conclusion: Our TUS protocol effectively ruled out clinically significant IPTX, eliminating routine CXR in 95.5% of patients. TUS is a safe alternative to CXR post-TBLCB, with CXR reserved for inconclusive TUS findings or symptomatic cases.

Background: Triple therapy (long-acting muscarinic antagonists (LAMAs), long-acting beta agonists (LABAs) and inhaled corticosteroids (ICSs)) is a recommended treatment for moderate-to-severe asthma at GINA Steps 4 and 5. However, little is known about the acceptance and use of triple therapy in everyday practice. The EU-LAMA Survey assessed specialists’ knowledge and views on triple therapy in daily practice. Methods: A 19-question survey was administered to 630 pulmonologists, allergologists, general practitioners, and internal medicine specialists in Poland (58%), Greece (27%), Sweden (6.3%), Slovenia (5.4%), and Austria (3.7%) using a dedicated online platform and computer-assisted web interviews. Results: The majority of the physicians were pulmonologists (59%), followed by allergologists (15.7%). For uncontrolled asthma at GINA Step 4, 81% of the respondents preferred increasing the ICS dose to the maximum level, whereas 76% opted to add LAMAs to medium-dose ICSs. At GINA Step 5, 79% of the respondents chose LAMAs first, followed by biological therapy (51%). Oral corticosteroids were favored over increasing the ICS dose and adding LAMAs. Triple therapy was mostly administered in one inhaler (70% and 82% at GINA Steps 4 and 5, respectively). Barriers to the use of LAMAs included a lack of reimbursement (31%), unclear guidelines (24%), lack of experience (18%), insufficient evidence (13%), fear of step-up regimens (10%), and the ease of increasing ICS doses (9%). Conclusion: Many physicians continue to rely on oral corticosteroids at GINA Steps 4 and 5 and infrequently refer patients to triple therapy or biological treatments at GINA Step 5.
