Book Description
Asthma is a chronic relapsing airways disease that represents a major public health problem worldwide. Intermittent exacerbations are provoked by airway mucosal exposure to pro-inflammatory stimuli, with RNA viral infections or inhaled allergens representing the two most common precipitants. In this setting, inducible signaling pathways the airway mucosa play a central role in the initiation of airway inflammation through production of antimicrobial peptides (defensins), cytokines, chemokines and arachidonic acid metabolites that coordinate the complex processes of vascular permeability, cellular recruitment, mucous hyper-secretion, bronchial constriction and tissue remodeling. These signals also are responsible for leukocytic infiltration into the submucosa, T helper-lymphocyte skewing, and allergic sensitization. Currently, it is well appreciated that asthma is a heterogeneous in terms of onset, exacerbants, severity, and treatment response. Current asthma classification methods are largely descriptive and focus on a single aspect or dimension of the disease. An active area of investigation on how to collect, use and visualize multidimensional profiling in asthma. This book will overview multidimensional profiling strategies and visualization approaches for phenotyping asthma. As an outcome, this work will facilitate the understanding of disease etiology, prognosis and/or therapeutic intervention. ​

Book Description
Asthma is a common chronic respiratory disease that causes substantial morbidity and has been challenging to treat due to its heterogeneous onset, environmental triggers, severity, and treatment response. To update the field on the rapid advances in this field, Precision Approaches to Heterogeneity in Asthma follows its highly successful predecessor, Heterogeneity in Asthma. In this new volume, noted authorities Allan R Brasier and Nizar N Jarjour and a cadre of leaders in the field incorporate new work advancing our understanding of phenotypes (endotypes) of disease, regional variations in ventilation, systems approach to analyzing the findings from studies of inducible phenotypes, and emerging results of biomarker-informed clinical trials. This work will facilitate our current understanding of the spectrum of disease etiology, prognosis, and the likelihood of responding to the range of available therapeutic interventions.

Book Description
Severe asthma is a form of asthma that responds poorly to currently available medication, and its patients represent those with greatest unmet needs. In the last 10 years, substantial progress has been made in terms of understanding some of the mechanisms that drive severe asthma; there have also been concomitant advances in the recognition of specific molecular phenotypes. This ERS Monograph covers all aspects of severe asthma – epidemiology, diagnosis, mechanisms, treatment and management – but has a particular focus on recent understanding of mechanistic heterogeneity based on an analytic approach using various ‘omics platforms applied to clinically well-defined asthma cohorts. How these advances have led to improved management targets is also emphasised. This book brings together the clinical and scientific expertise of those from around the world who are collaborating to solve the problem of severe asthma.

Book Description
This book provides a practical, stepwise, evidence-based approach to effective management of patients with difficult to treat asthma. The impact of asthma on morbidity and healthcare utilization increases exponentially with severity. Severe refractory asthma accounts for less than 5% of all asthma. Its prevalence, however, is often overestimated as there are several other confounding factors that make asthma ‘difficult to treat’. Many novel (albeit expensive) therapies are now available and providers caring for patients with severe asthma are charged with selecting the best evidence treatment. This calls for complex and nuanced decision-making. Whether people with asthma gain and maintain control over their condition depends not only on the availability of effective drugs, but also multiple patient and healthcare provider behaviors. Therefore, now more than ever, it has become increasingly important to differentiate “difficult” from “severe refractory” asthma to allow identification of patients most likely to benefit from these therapies. This volume delves into the current understanding of mechanisms and increasingly recognized heterogeneity of this complex disease. It discusses a structured approach to identification and optimization of factors contributing to poor asthma control, including nonadherence, comorbidities and occupational/environmental triggers. The book includes ‘state of the art’ reviews on recent advances in traditional and targeted asthma therapies, as well as a glimpse into what the future may hold. Highlights include a comprehensive guide to management of severe asthma in children and pregnancy, as well as practical considerations to management of asthma based on different clinical phenotypes. Each chapter is authored by leading experts in the field who share their own clinical approach. This is an ideal guide for clinical pulmonologists and allergist/immunologists, as well as primary care providers, physician extenders in specialty practice, physicians in pulmonary/allergy training, and even industry partners.

Book Description
This book provides a comprehensive overview of how to use MRI for the imaging of lung disease. Special emphasis is placed on routine applications and the clinical impact of MRI in each setting. In addition, current technological developments are reviewed and information presented on dedicated applications of MRI in preclinical and translational research, clinical trials, and specialized institutions. During the past two decades, significant advances in the technology have enabled MRI to enter and mature in the clinical arena of chest imaging. Standard protocols are now readily available on MR scanners, and MRI is recommended as the first- or second-line imaging modality for a variety of lung diseases, not limited to cystic fibrosis, pulmonary hypertension, and lung cancer. The benefits and added value of MRI originate from its ability to both visualize lung structure and provide information on different aspects of lung function, such as perfusion, respiratory motion, ventilation, and gas exchange. On this basis, novel quantitative surrogates for lung function and therapy control (imaging biomarkers) are generated. The second edition of MRI of the Lung has been fully updated to take account of recent advances. It is written by an internationally balanced team of renowned authors representing all major groups in the field.

Book Description
Asthma is a chronic airway disease affecting over 300 million people worldwide with an expected increase of an additional 100 million by 2025. Past decade has observed a notable increase in asthma prevalence on both national and global levels with highest rates observed in western countries (about 30%). Over the past 40 years, a drastic increase in global prevalence, morbidity, mortality, and economic burden have been observed due to asthma especially in children. The rising numbers of hospital admissions for asthma, especially young children, reflect an increase in severe asthma, poverty and lack of proper disease management. Worldwide, approximately 180,000 deaths annually are caused due to this condition. The financial burden on a single asthma patient per year in different western countries ranges from US$300–1,300. Asthma is an intricate respiratory disorder with differences in its severity, natural history and hence treatment response. These differences in intensities of various presentations such as bronchial hyper-responsiveness, airway inflammation, mucus production, airflow obstruction make asthma a heterogeneous disease. The mainstay of current therapies for asthma includes inhaled corticosteroids, phosphodiesterase inhibitors, leukotriene modifiers and β2-adrenoceptor agonists. Some of the currently available drugs are efficient in one or more aspects. However the associated side effects or heterogeneity of the disease limit their usefulness and efficacy, thereby putting a demand on development of new drugs and therapies. On the other hand, asthma has also been treated/managed via herbal medications. These approaches have been described in Unani, Ayurvedic or Chinese system of medicine since antiquity. In fact, several anti-asthmatic drugs were developed from herbs commonly utilized in the non-Western system of medicine. This book focuses on the pathophysiology of asthma, its medication (both herbal and modern), limitations and their future prospects.
