severe refractory asthma

Usman Maqsood, Nehal Patel
We describe a case of near-fatal asthma, treated successfully by initiation of extracorporeal membrane oxygenation (ECMO). A 29-year-old woman, known asthmatic on steroid inhalers, inhaled/nebulised bronchodilators, long-term oral prednisolone, theophylline and montelukast, presented with acute shortness of breath. She deteriorated following initial treatment with nebulised bronchodilators and magnesium sulfate requiring intubation and mechanical ventilation. Severe bronchospasm ensued following mechanical ventilation and peak airway pressures remained at 55 cm H2 O with intrinsic positive end expiratory pressure(PEEP) of 14 cm H2 O...

BACKGROUND: Airway type 2 inflammation is usually corticosteroid sensitive, but the role of type 2 inflammation as a mechanism of asthma in patients on high dose inhaled corticosteroids (ICS) is uncertain. OBJECTIVE: To determine if airway type 2 inflammation persists in patients treated with ICS and to evaluate the clinical features of patients with steroid resistant airway type-2 inflammation. METHODS: We used qPCR to generate a composite metric of type-2 cytokine gene expression (type 2 Gene Mean, "T2GM") in induced sputum cells from healthy controls, severe asthma patients on ICS (n=174), and non-severe asthma patients on ICS (n=85)...

The epithelial cytokines IL-33, thymic stromal lymphopoietin (TSLP), and IL-25 have been implicated in asthma pathogenesis because they promote Th2-type cytokine synthesis, but their expression is relatively poorly documented in "real-life" human asthma. Using bronchoalveolar lavage fluid (BALF), we measured airway concentrations of these mediators and compared them with those of Th1- and Th2-type cytokines, airway infiltration of neutrophils and eosinophils, and lung function in a large group of asthmatic patients with a range of disease severity ( n = 70) and control subjects ( n = 30)...

BACKGROUND: Quantitative computed tomography (QCT) biomarkers of airway morphology hold potential for understanding and monitoring regional airway remodeling in asthma. OBJECTIVE: We sought to determine if the change of airway lumen area between TLC and FRC lung volumes measured from CT imaging data was correlated with severe outcomes in asthma patients. METHODS: We studied 152 asthma patients (90 female and 62 male) and 33 normal subjects (12 female and 21 male) with QCT...

Both asthma and COPD are complex, heterogeneous conditions comprising a wide range of phenotypes, some of which are refractory to currently available treatments. Elucidation of these phenotypes and identification of biomarkers with which to recognize them and guide appropriate treatment remains a priority. This review describes the utility of blood eosinophils as a surrogate biomarker of eosinophilic airway inflammation, a common feature of specific asthma and COPD phenotypes. The role of blood eosinophils in airway disease is described, as is their relevance in reflecting airway eosinophilia...

Background: Allergic Rhinitis (AR) is a high-prevalence disease. In Europe about 25% of the general population is affected, and in Italy the prevalence is estimated to be 19.8%. The Allergic Rhinitis and its Impact on Asthma (ARIA) international document underlined that the prevalence of severe or refractory or overlapping rhinitis is increasing and represents a non-negligible socio-economic burden. In general, despite the social healthcare costs, allergic rhinitis remains underestimated, not sufficiently controlled and often undertreated...

BACKGROUND: Asthmatic cough is often refractory to standard treatments such as inhaled corticosteroids and long-acting β2 agonists (ICS/LABA). Tiotropium may modulate cough reflex sensitivity of acute viral cough, but its efficacy in asthmatic cough remains unknown. OBJECTIVE: To evaluate whether tiotropium improves cough and cough reflex sensitivity in asthmatic patients refractory to ICS/LABA. METHODS: Seventeen consecutive asthmatic patients with chronic cough despite the use of ICS/LABA [13 females; 43...

In severe asthma, poor control could reflect issues of medication adherence or inhaler technique, or that the condition is refractory. This study aimed to determine if an intervention with (bio)feedback on the features of inhaler use would identify refractory asthma and enhance inhaler technique and adherence.Patients with severe uncontrolled asthma were subjected to a stratified-by-site random block design. The intensive education group received repeated training in inhaler use, adherence and disease management...

BACKGROUND: Patients with difficult-to-control asthma consume 50-60% of healthcare costs attributed to asthma and cost approximately five-times more than patients with mild stable disease. Recent evidence demonstrates that not all patients with asthma have a typical type 2 (T2)-driven eosinophilic inflammation. These asthmatics have been called 'T2-low asthma' and have a minimal response to corticosteroid therapy. Adjustment of corticosteroid treatment using sputum eosinophil counts from induced sputum has demonstrated reduced severe exacerbation rates and optimized corticosteroid dose...

Asthma therapy with monoclonal antibodies is a promising and effective approach for those with a severe and refractory type of disease. Although such a targeted therapy is considered to be safe, unusual complications may occur. We present a case of a 45 year-old female patient with severe allergic asthma and chronic spontaneous urticaria, who developed autoimmune polyendocrine syndrome type 2 (APS-2) after 26 months of omalizumab administration. The patient was diagnosed with primary adrenal insufficiency (Addison's disease) and Hashimoto's thyroiditis accompanied by autoimmune atrophic gastritis...

INTRODUCTION: Chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma often coexist and thus treating both with one intervention is an attractive strategy. OBJECTIVE: To prospectively evaluate whether treatment with the monoclonal antibody against IgE Omalizumab for severe allergic asthma also effectively treats co-existent CRSwNP. METHODS: SNOT-22 and the ACQ-7 scores were recorded at 4 and 16 weeks of treatment in a cohort of patients with both CRSwNP and severe refractory allergic asthma treated with Omalizumab (n=13) according to UK guidelines for their severe asthma...

Severe asthma accounts for only a small proportion of the children with asthma, but a disproportionately high amount of resource utilization and morbidity. It is a heterogeneous entity and requires a step-wise, evidence based approach to evaluation and management by pediatric subspecialists. The first step is to confirm the diagnosis by eliciting confirmatory history and objective evidence of asthma and excluding possible masquerading diagnoses. The next step is to differentiate difficult-to-treat asthma, asthma which can be controlled with appropriate management, from asthma which requires the highest level of therapy to maintain control or remains uncontrolled despite management optimization...

BACKGROUND: The use of extracorporeal membrane oxygenation (ECMO) in cases of near-fatal asthma (NFA) has increased, but the benefits and potential complications of this therapy have yet to be fully investigated. METHODS: Cases were extracted from the Extracorporeal Life Support Organization Registry between March 1992 and March 2016. All patients with a diagnosis of asthma (according to the International Classification of Diseases 9th edition), who also received ECMO, were extracted...

BACKGROUND: To determine the correlation between asthma and hiatal hernia (HH) in patients with gastroesophageal reflux disease (GERD)-related asthma requiring laparoscopic anti-reflux surgery. METHODS: One hundred and thirty-six GERD patients with medically refractory asthma with (80 patients) or without HH (56 patients) were enrolled. Gastroesophageal reflux disease was assessed by endoscopy, esophageal manometry, reflux monitoring and symptom questionnaires, and treated with laparoscopic Nissen fundoplication (LNF) or LNF with concomitant hiatal hernia repair (LNF-HHR)...

Severe asthma affects between 5% and 10% of patients with asthma worldwide and requires best standard therapies at maximal doses, but there is a subgroup of patients refractory to all treatments. We share a case report of a 53-year-old woman with a history of severe allergic asthma that progressively worsened over the years despite the best therapy. She had been hospitalized 35 times, including nine admissions to the respiratory intensive care unit due to severe exacerbations. To rule out other possible diagnoses, several investigations were performed, such as computed tomography scan of the chest and neck, fiberoptic laryngoscopy, antineutrophil cytoplasmic antibodies, and complete blood cell count...

The heterogeneous nature of asthma has been understood for decades, but the precise categorization of asthma has taken on new clinical importance in the era of specific biologic therapy. The simple categories of allergic and non-allergic asthma have given way to more precise phenotypes that hint at underlying biologic mechanisms of variable airflow limitation and airways inflammation. Understanding these mechanisms is of particular importance for the approximately 10% of patients with severe asthma. Biomarkers that aid in phenotyping allow physicians to "personalize" treatment with targeted biologic agents...

INTRODUCTION: Increased vascularity may lead to loss of heat in the airways and may modulate exhaled breath temperature (EBT). Increased EBT has been associated with uncontrolled asthma. AIM: We wanted to determine whether the measurement of EBT in optimally treated asthmatic patients is influenced by the increased vascular permeability and whether Vascular endothelial growth factor (VEGF) is implicated in the above process. Furthermore, to assess the impact of asthma severity on EBT values...
