Airway remodeling in asthma contributes to airway hyperreactivity, loss of lung function and persistent symptoms. Current therapies do not adequately treat the structural airway changes associated with asthma. Statin drugs have improved respiratory health and their therapeutic potential in asthma has been tested in clinical trials. However, the mechanism of action of statins in this context has remained elusive. The present study hypothesized that atorvastatin treatment of ovalbumin-exposed mice attenuates early features of airway remodeling via a mevalonate-dependent mechanism...

Over the last three decades, monoclonal antibodies (MAbs) have made a striking transformation from scientific tools to powerful human therapeutics. Muromonab CD3 a murine MAb, was first FDA approved therapeutic MAb for prevention of kidney transplant rejection. Since its approval in 1986, there has been decline in the further application and approvals until the late 1990s when the first chimeric Mab, Rituximab was approved for the treatment of low grade B cell lymphoma in 1997. With the approval by licensing authorities of chimeric, followed by humanized and then fully human monoclonal antibodies, rate of approval and monoclonal antibodies available in the market for the treatment of various diseases has increased dramatically...

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets...

Increasing dependence on advanced technologies in the 21st century has created a dilemma between the practice and business of medicine. From information technology to robotic surgery, new technologies have expanded treatment possibilities and have potentially improved patient outcomes and safety. Simultaneously, their escalating costs limit access for certain patients and health care facilities. Nevertheless, medical decisions should not simply be based on cost. Input from physicians and other health care specialists as well as adherence to best practice position statements, are vital to implementing truly cost-effective strategies in medicine...

Symptoms, including night-time awakenings, affect the quality of life of people with asthma. Fluticasone furoate/vilanterol (FF/VI) reduces exacerbations, improves lung function, and rescue-free and symptom-free 24-hour periods in patients with asthma. These post-hoc analyses compared daytime and night-time symptoms in patients with asthma who received FF/VI, versus FF, fluticasone propionate (FP) or placebo. Daytime and night-time symptoms were collected via electronic daily diary cards in three Phase III randomized studies of once-daily FF/VI in patients with uncontrolled asthma on inhaled corticosteroids (ICS) ±long-acting beta2-agonists (LABA) (n = 609/1039/586)...

REVIEW

The recognition of invading pathogens and endogenous molecules from damaged tissues by toll-like receptors (TLRs) triggers protective self-defense mechanisms. However, excessive TLR activation disrupts the immune homeostasis by sustained pro-inflammatory cytokines and chemokines production and consequently contributes to the development of many inflammatory and autoimmune diseases, such as systemic lupus erythematosus (SLE), infection-associated sepsis, atherosclerosis, and asthma. Therefore, inhibitors/antagonists targeting TLR signals may be beneficial to treat these disorders...

BACKGROUND: Methacholine dose-response curves illustrate pharmacologic bronchoprotection against methacholine-induced airway hyperresponsiveness and can be used to quantitate changes in airway sensitivity (position), reactivity (slope), and maximal responsiveness following drug administration. Our objective was to determine the influence of single-dose glycopyrronium (long-acting muscarinic antagonist) and indacaterol (ultra-long acting β2 agonist), as monotherapy and in combination, on the methacholine dose-response curve of mild asthmatics and to compare these findings with a non-asthmatic control curve...

Bronchial Thermoplasty (BT) is an endoscopic treatment for moderate-to-severe asthma patients who are uncontrolled despite optimal medical therapy. Effectiveness of BT has been demonstrated in several randomized clinical trials. However, the asthma phenotype that benefits most of this treatment is unclear, partly because the mechanism of action is incompletely understood. BT was designed to reduce the amount of airway smooth muscle (ASM), but additional direct and indirect effects on airway pathophysiology are expected...
