    Abstract This is an exciting time to be conducting asthma research. The recent development of targeted asthma biologics has validated the power of basic research to discover new molecules amenable to therapeutic intervention. Advances in high-throughput sequencing are providing a wealth of "omics" data about genetic and epigenetic underpinnings of asthma, as well as about new cellular interacting networks and potential endotypes in asthma. Airway epithelial cells have emerged not only as key sensors of the outside environment but also as central drivers of dysregulated mucosal immune responses in asthma. Emerging data suggest that the airway epithelium in asthma remembers prior encounters with environmental exposures, resulting in potentially long-lasting changes in structure and metabolism that render asthmatic individuals susceptible to subsequent exposures. Here we summarize recent insights into asthma biology, focusing on studies using human cells or tissue that were published in the past 2 years. The studies are organized thematically into 6 content areas to draw connections and spur future research (on genetics and epigenetics, prenatal and early-life origins, microbiome, immune and inflammatory pathways, asthma endotypes and biomarkers, and lung structural alterations). We highlight recent studies of airway epithelial dysfunction and response to viral infections and conclude with a framework for considering how bidirectional interactions between alterations in airway structure and mucosal immunity can lead to sustained lung dysfunction in asthma.

    Abstract The definition of asthma has evolved over the years with significant heterogeneity of the disease increasingly recognized. Complex gene and environment interactions result in different pheno-endotypes of asthma that respond differently to the same treatment. Multiple studies have revealed pharmacogenomic and endophenotypic factors that predict treatment response to standard therapies for asthma. Recent advances in biologic medications have enabled a more tailored approach to the care of patients with moderate to severe asthma, taking into consideration clinical traits and measurable biomarkers. This chapter will review heterogeneity in treatment response to different medication classes for asthma: inhaled and systemic corticosteroids, beta-2 agonists, leukotriene modifiers, muscarinic antagonists, macrolides, and biologics.

    Abstract Pulmonary embolism (PE) is a serious condition that often poses a diagnostic challenge. We report a case of a 57-year-old man with tobacco dependence who presented with multiple trauma, with chest imaging findings concerning for malignancy. While performing bronchoscopy with endobronchial ultrasound (EBUS), an echogenic material was incidentally found in the left pulmonary artery. Computed tomography pulmonary angiography (CTPA) was immediately obtained and confirmed the diagnosis of PE. This case illustrates the utility of routine pulmonary artery examination during EBUS procedures in patients at risk of PE and the importance of prompt management including confirmation with CTPA.

    Abstract Purpose of review: There are multiple FDA-approved biologics to treat poorly controlled moderate-to-severe asthma. Given the heterogeneity of asthma and the lack of head-to-head data between biologics, selecting the best biologic for a patient can be difficult. This review summarizes the key literature to date, in hopes of facilitating an evidence-based approach to selecting the most appropriate biologic for patients with asthma.
    Recent findings: In addition to unique mechanisms of action, there is increasing literature on predictors of response to each biologic, such as sensitizations to aeroallergens, peripheral eosinophil count, total serum IgE, and exhaled nitric oxide. Biologics available for asthma are also being increasingly studied in comorbid conditions with asthma, and this may facilitate selecting the most appropriate biologic for a patient. In the absence of head-to-head studies, there is literature of switching between biologics whenever necessary.
    Summary: The authors outline an approach to selecting a biologic based on various considerations, and hope this suggested approach facilitates selecting the biologic most suitable for each individual with poorly controlled moderate-to-severe asthma.

    Abstract Pancreatic pseudocyst formation with extension into the mediastinum is an uncommon complication of pancreatitis that can result in numerous pulmonary and cardiac complications. We present a case of a 56-year-old man with a history of recurrent pancreatitis who presented with haemoptysis. His initial workup was consistent with diffuse alveolar haemorrhage for which he was treated with glucocorticoids. After failure to improve, further imaging demonstrated a complex fluid collection in the mediastinum consistent with extension of his pre-existing pancreatic pseudocyst, leading to erosion into the right lower lobe of the lung. This case highlights a rare pulmonary complication of pancreatitis and underscores the importance of proper identification of this condition to guide successful management.

    Abstract Oral corticosteroid (OCS) use in severe asthma remains all too common despite advances in asthma treatment. Use of OCS is associated with significant toxicity that can have a lasting adverse impact on a patient's overall health. Monoclonal antibodies have been developed that reduce both the rate of occurrence of OCS-treated exacerbations and the OCS requirements in patients with oral corticosteroid-dependent asthma. This article describes strategies to prevent and best manage endocrine complications associated with OCS use and provides guidance on OCS dose management after the introduction of steroid-sparing therapies. (1) We identify OCS-dependent patients and assess for comorbidities including bone health, glycemic control, and adrenal function; (2) we begin attempts at OCS dose optimization before or soon after introducing a steroid-sparing biologic therapy; (3) we taper OCS, using explicit criteria for asthma control; (4) we assess hypothalamic-pituitary-adrenal axis integrity once a physiologic dose of OCS is achieved to guide further the rate of OCS taper; and (5) we manage corticosteroid-related comorbidities as detailed in this article.

    Abstract Background: Confirmation of effectiveness of asthma biologics in the real world is desirable because patient characteristics and experiences may differ from those included in randomized controlled trials.
    Objective: To evaluate real-world effectiveness of asthma biologics and identify predictors of response.
    Methods: We performed a retrospective study in patients with severe asthma receiving biologics. The primary outcome was change in clinically significant exacerbations at 12 months after starting biologic therapy, compared with 12 months before. Secondary outcomes were change in severe exacerbations, maintenance oral corticosteroid (OCS) dose, prebronchodilator forced expiratory volume in 1 second (FEV1), and asthma control test scores. Subgroup analyses were performed for subjects who were biologic naive or not. A stepwise logistic regression model was performed to compare responders to nonresponders.
    Results: A total of 112 patients were included. Biologic therapy was associated with a 59% reduction in clinically significant exacerbations (P < .001), 65% reduction in severe exacerbations (P < .001), and 54% reduction in maintenance OCS dose (P = .001) in the 12 months after starting therapy. Biologics also resulted in improvement in prebronchodilator FEV1 (P = .002) and Asthma Control Test score (P < .001). Subjects who were previously on another biologic also experienced significant improvements in exacerbation frequency, maintenance OCS dose, and asthma control. Responders were more likely to be nonsmokers and have higher baseline FEV1, gastroesophageal reflux disease, and eosinophil counts greater than 500 cells/μL.
    Conclusion: In a real-world setting, biologic therapy in asthma is effective in improving exacerbations, asthma control, and lung function. Patients who have a suboptimal response to 1 biologic can still benefit from treatment with a different biologic.
