INTRODUCTION: Asthma with adult onset and elevated blood eosinophils is a difficult-to-treat subgroup. This post hoc analysis evaluated reslizumab, an anti-interleukin-5 monoclonal antibody, in patients with late-onset eosinophilic asthma. METHODS: Data from two 52-week placebo-controlled trials of reslizumab IV 3 mg/kg every 4 weeks in patients aged 12-75 years with inadequately controlled asthma, ≥1 asthma exacerbation within 12 months, and screening blood eosinophils ≥400/μL (NCT01287039/NCT01285323) were stratified by age of asthma onset (<40 or ≥40 years)...

Cytokine antagonists are monoclonal antibodies that offer new treatment options for refractory asthma but will also increase complexity because they are effective only for patients with certain asthma subtypes that remain to be more clearly defined. The clinical and inflammatory heterogeneity within refractory asthma makes it difficult to manage the disease and to determine which, if any, biologic therapy is suitable for a specific patient. The purpose of this article is to provide a data-driven discussion to clarify the use of biologic therapies in patients with refractory asthma...

The influence of obesity on development, severity and prognosis of both asthma and COPD is attracting growing interest. The impact of obesity on the respiratory system ranges from structural modifications (decline of total lung capacity) to humoral alterations. Adipose tissue strongly contributes to the establishment of an inflammatory state being an important source of adipokines. Amongst adipokines, adiponectin is an important component of organ cross talk with adipose tissue exerting protective effects on a variety of pathophysiological processes...

The main driving mechanism during an asthma attack is the hyper-constrictions of airway smooth muscle (ASM), which reduces the airway lumen and makes normal breathing difficult. In spite of some noticeable side effects, bronchodilator drugs such as salbutamol are used to alleviate these symptoms by inducing temporary relaxation of the contracted ASM. In vitro studies have shown that mechanical oscillation can induce relaxation in isolated contracted ASM obtained from healthy subjects but not from asthmatics...

Despite the availability of guideline recommendations, diagnostic confusion between COPD and asthma appears common, and often it is very difficult to decide whether the obstruction is caused by asthma or COPD in a patient with airway obstruction. However, there are well-defined features that help in differentiating asthma from COPD in the presence of fixed airflow obstruction. Nonetheless, the presentations of asthma and COPD can converge and mimic each other, making it difficult to give these patients a diagnosis of either condition...

INTRODUCTION: The obesity epidemic is reflected by increasing numbers of morbidly obese patients being admitted to intensive care units (ICUs). These are complicated patients whose care involves many diagnostic and treatment challenges. We are presenting a fatal case of super obesity, hypoventilation, and multi-organ failure known as malignant obesity hypoventilation syndrome (MOHS). CASE PRESENTATION: 35 year old African American gentleman with a body mass index (BMI) of 115 kg/m(2) presented to the hospital with respiratory distress...

OBJECTIVE: Bronchial thermoplasty (BT) is a novel treatment for severe asthma. Its mode of action and ideal target patient group remain poorly defined, though clinical trials provided some evidence on efficacy and safety. This study presents procedural and short-term safety evidence from routine UK clinical practice. METHODS: Patient characteristics and safety outcomes (procedural complications, 30-day readmission and A&E attendance, length of stay) were assessed using two independent data sources, the British Thoracic Society UK Difficult Asthma Registry (DAR) and Hospital Episodes Statistics (HES) database...

BACKGROUND: Cough is a common symptom experienced by athletes, particularly after exercise. We performed a systematic review to assess the following in this population: (1) the main causes of acute and recurrent cough, either exercise-induced or not, (2) how cough is assessed, and (3) how cough is treated in this population. From the systematic review, suggestions for management were developed. METHODS: This review was performed according to the CHEST methodological guidelines and Grading of Recommendations Assessment, Development and Evaluation framework until April 2015...

Omalizumab therapy of non-atopic asthmatics reduces bronchial mucosal IgE and inflammation and preserves/improves lung function when disease is destabilised by staged withdrawal of therapy.18 symptomatic, non-atopic asthmatics were randomised (1:1) to receive omalizumab or identical placebo treatment in addition to existing therapy for 20 weeks. Bronchial biopsies were collected before and after 12-14 weeks of treatment, then the patients destabilised by substantial, supervised reduction of their regular therapy...

Cystic fibrosis (CF) is the most common genetically inherited condition in European-derived populations. However, it is being increasingly recognised in other populations, including people of Asian, Black African and Caribbean descent. We present a case detailing the diagnosis of CF in a 12-year-old patient of Egyptian background who had been treated for difficult asthma. In doing so, we aim to highlight the importance of considering CF in all patients, regardless of ethnicity.

We describe an interesting case of severe asthma who was not showing satisfactory response to standard treatment. Investigations revealed him to be suffering from allergic bronchopulmonary aspergillosis (ABPA). After starting systemic steroids he showed marked improvement initially only to have recurrent symptoms within a year. He was investigated further and found to have chronic pulmonary aspergillosis in the form of chronic cavitary pulmonary aspergillosis (CCPA) and aspergilloma as also the presence of selective IgA deficiency...

Adult-onset eosinophilic asthma is increasingly recognised as a severe and difficult-to-treat subtype of asthma. In clinical practice, early recognition of patients with this asthma subtype is important because it may have treatment implications. Therefore, physicians need to know the distinct characteristics of this asthma phenotype. The objective of the present study was to determine the characteristic profile of patients with adult-onset eosinophilic asthma. 130 patients with adult-onset (>18 years of age) asthma and high blood eosinophil counts (≥0...

BACKGROUND: Studies show that mepolizumab can reduce the frequency of clinically significant exacerbations in patients with severe eosinophilic asthma, compared with placebo. However, important events such as hospitalizations and emergency room visits are rare and difficult to characterize in single studies. OBJECTIVE: We sought to compare hospitalization or hospitalization and/or emergency room visit rates in patients with severe eosinophilic asthma treated with mepolizumab or placebo in addition to standard of care for at least 24 weeks...

Asthma is a lung disorder triggered by various airborne factors in susceptible individuals. Although generally controlled, asthma can be severe and difficult to treat. Presently, increasing numbers of pharmaceuticals capable of blocking or mimicking specific endogenous molecules are undergoing clinical trials in asthmatic individuals whose symptoms are poorly controlled despite adherence to guideline therapies. Unfortunately, only a few, meticulously selected patients have been found to minimally benefit. These findings not only confirm that the molecular pathogenesis of severe asthma is variable between patients but also suggest that each molecular defect is likely to contribute little on its own in each patient...

Despite notable advances in the survival and management of preterm infants in recent decades, chronic lung disease remains a common complication. Approximately one in three infants born preterm (< 32 weeks of gestation) are hospitalized with respiratory problems (mainly due to infections) in their first 2 years of life, and the risk of childhood wheezing is three times higher in this population. By comparison with infants born at term, there seems to be a higher incidence of respiratory morbidity in those born preterm, even in the absence of bronchopulmonary dysplasia (BPD) and in late-preterm babies...

BACKGROUND: Asthma and obesity are highly prevalent in children, and are interrelated resulting in a difficult-to-treat asthma-obesity phenotype. The exact underlying mechanisms of this phenotype remain unclear, but decreased physical activity (PA) could be an important lifestyle factor. We hypothesize that both asthma and overweight/obesity decrease PA levels and interact on PA levels in asthmatic children with overweight/obesity. METHODS: School-aged children (n = 122) were divided in 4 groups (healthy control, asthma, overweight/obesity and asthma, and overweight/obesity)...

REVIEW

BACKGROUND: Bronchodilators are a central component for treating exacerbations of chronic obstructive pulmonary disease (COPD) all over the world. Clinicians often use nebulisers as a mode of delivery, especially in the acute setting, and many patients seem to benefit from them. However, evidence supporting this choice from systematic analysis is sparse, and available data are frequently biased by the inclusion of asthma patients. Therefore, there is little or no formal guidance regarding the mode of delivery, which has led to a wide variation in practice between and within countries and even among doctors in the same hospital...

BACKGROUND: There has been a recent increase in the number of patients suffering from bone and joint diseases, as a consequence of corticosteroids administration. There are more patients treated with low dose of GCs under long-term conditions in clinical, such as effect of GCs on Rheumatoid arthritis, Crohn's disease and Asthma patients. Hence, it was difficult for doctor to determine which problem occur first - OP or ON; however, there was no clinical report previously in the literature, and there was no effective animal model of OP and ON about low dose GCs...

AIM: We determined the proportion of asthma patients under specialist care who remain difficult-to-treat and might benefit from systematic assessment. We additionally report the characteristics and indications for referral in 90 patients who received systematic assessment for difficult asthma. METHODS: We conducted a three-month prospective audit of our hospital's general asthma clinic. We then analyzed consecutive patients over 18 months referred on for systematic assessment of difficult asthma...
