A Combination of Mepolizumab and Omaluzimab injections for severe asthma. INTRODUCTION: Patients with severe persistent asthma account for a large proportion of asthma morbidity and health care expenditures. In this case report we describe the use of a combination of omalizumab and mepolizumab in severe asthma with elevated IgE levels and eosinophilic phenotype. CASE STUDY: We are treating a 55 year old woman with severe persistent eosinophilic asthma and elevated IgE levels...

Bronchial thermoplasty is a treatment for asthma. It is currently unclear whether its histopathological impact is sufficiently explained by the proportion of airway wall that is exposed to temperatures necessary to affect cell survival.Airway smooth muscle and bronchial epithelial cells were exposed to media (37-70°C) for 10 s to mimic thermoplasty. In silico we developed a mathematical model of airway heat distribution post-thermoplasty. In vivo we determined airway smooth muscle mass and epithelial integrity pre- and post-thermoplasty in 14 patients with severe asthma...

Bronchial thermoplasty (BT) is a bronchoscopic treatment for patients with severe asthma who remain symptomatic despite optimal medical therapy. In this "expert best practice" paper, the background and practical aspects of BT are highlighted. Randomized, controlled clinical trials have shown BT to be safe and effective in reducing severe exacerbations, improving quality of life, and decreasing emergency department visits. Five-year follow-up studies have provided evidence of the functional stability of BT-treated patients with persistence of a clinical benefit...

Rationale Bronchial thermoplasty is a relatively new but effective treatment in asthmatic subjects who do not respond to conventional therapy. While the favoured mechanism is ablation of the airway smooth muscle layer, because bronchial thermoplasty treats only a small number of central airways, there is ongoing debate regarding its precise method of action. Objectives Elucidate the underlying method of action behind bronchial thermoplasty. Methods We employ a combination of extensive human lung specimens and novel computational methods...

BACKGROUND: The most common adverse effect of bronchial thermoplasty (BT) is short-term aggravation of asthma immediately following the procedure. However, the magnitude and duration of this deterioration, and its predisposing factors are yet to be quantitated. This information will be particularly important as BT is extended to include more severely obstructed patients. METHODS: In this prospective, observational study of 20 consecutive patients with very severe asthma undergoing BT, post bronchodilator FEV1 was measured in the 30 min prior to surgery, and then 24 h following the 60 procedures...

Bronchial thermoplasty (BT) is a recently introduced bronchoscopic treatment for patients with asthma refractory to pharmacotherapy. Intraprocedural sedation management is important for successful performance of BT. However, the results of general anesthesia in patients undergoing BT have not been well described. The aim of this study was to evaluate the feasibility and safety of general anesthesia in patients undergoing BT. We retrospectively reviewed the records of 10 consecutive BT treatments performed under general anesthesia in 4 patients...

Nonadherence to inhaled preventers impairs asthma control. Electronic monitoring devices (EMDs) can objectively measure adherence. Their use has not been reported in difficult asthma patients potentially suitable for novel therapies, i.e. biologics and bronchial thermoplasty.Consecutive patients with difficult asthma were assessed for eligibility for novel therapies. Medication adherence, defined as taking >75% of prescribed doses, was assessed by EMD and compared with standardised clinician assessment over an 8-week period...

BACKGROUND: Bronchial thermoplasty (BT) is a non-pharmacological intervention for severe asthma whose mechanism of action is not completely explained by a reduction of airway smooth muscle (ASM). In this study we analyzed the effect of BT on nerve fibers and inflammatory components in the bronchial mucosa at 1 year. METHODS: Endobronchial biopsies were obtained from 12 subjects (mean age 47 ± 11.3 years, 50% male) with severe asthma. Biopsies were performed at baseline (T0) and after 1 (T1), 2 (T2) and 12 (T12) months post-BT, and studied with immunocytochemistry and microscopy methods...

Bronchial thermoplasty (BT) is a bronchoscopic treatment for severe asthma using thermal energy to reduce smooth muscle in the bronchial wall. A 47-year-old man underwent BT for uncontrolled severe asthma despite maximal pharmacological treatment. After a third procedure, he experienced hypoxaemia because of complete bilateral upper lobe atelectasis. A pulmonary cyst suddenly emerged in to the right middle lobe, associated with the pneumothorax on postoperative day 6, and a chest drainage tube was inserted...

RATIONALE: Inflammation and smooth muscle dysfunction are integral components of severe asthma that contribute to luminal obstruction causing airflow limitation, ventilation heterogeneity, and symptoms. This is important for guiding treatment decisions directed at the inflammatory (e.g., anti-T-helper cell type 2 monoclonal antibodies) and noninflammatory, smooth muscle-mediated (e.g., bronchial thermoplasty) components of severe asthma. OBJECTIVES: To investigate the contribution of eosinophilic bronchitis and smooth muscle dysfunction to magnetic resonance imaging (MRI) ventilation heterogeneity in patients with severe asthma...

Bronchial thermoplasty (BT) is a non-pharmacologic therapy for severe asthma. The proper procedure and perioperative management are very important for the effectiveness and safety of BT. China Asthma Alliance assembled a group of experts in asthma and BT to review the literature, drew on their own experiences, discussed, and then finalized by consensus to establish this standard practice guideline. This practice guideline is designed to guide clinicians as to proper patients' selection, preoperative assessment, postoperative management and follow-up...

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...

Background: Asthma is a common condition and there remains a subset of patients who are poorly controlled on maximal therapy. Bronchial thermoplasty (BT) is a bronchoscopic therapy using radiofrequency energy to reduce airway smooth muscle, which has been shown to improve asthma control although further evidence regarding long-term efficacy and safety is required. Aim: We aimed to demonstrate safety and efficacy of BT on extended follow-up. Our initial experience with this group was previously reported in 2016, where patients were shown to have a significant improvement in asthma control test (ACT) scores 1-year post-treatment...

BACKGROUND: Severe asthma poses significant disease-related and economic burdens in the United States. Challenges in practice include how to define "severe asthma" for a given patient, knowing which are the right tests to perform and when, and having a better understanding of a patient's asthma phenotype. Furthermore, current guidelines do not address a clear, practical approach to treatment that is based on a patient's asthma phenotype. OBJECTIVE: To develop a consensus on the definition of severe asthma, the role of biomarkers and phenotyping severe asthma, and the use of newer biologic therapies and bronchial thermoplasty to help guide practicing clinicians...

Asthma is an incurable chronic disease affecting approximately 24 million people in the United States. The hallmark features of asthma are reversible airflow obstruction, airway hyperresponsiveness, airway inflammation, bronchoconstriction, and excessive mucus secretion. Clinical symptoms include episodic or persistent breathlessness, wheezing, cough, or chest tightness/pressure. Forty-five percent of asthmatics continue to have yearly exacerbations and the disease is responsible for approximately 3,600 annual deaths...
