Long-acting bronchodilators improve Health Related Quality of Life in patients with COPD

Summary Background Long-acting bronchodilators are first-line treatment for chronic obstructive pulmonary disease (COPD), and their efficacy on lung function and clinical parameters is recognized. Objective To explore the available evidence about the effects of long acting bronchodilators on Health Related Quality of Life (HRQoL) and Health Status (HS) in clinical research. Methods Randomized controlled trials published till December 2012 evaluating HRQoL/HS in COPD by means of validated questionnaires were analysed. Results Fifty-one trials on Long acting β 2 agonist (LABA) and Long acting Anticholinergic (LAMA) met the inclusion criteria. A total of 37,225 moderate-severe COPD patients testing 6 drugs, 12 different devices and 22 different dosages, with a study duration ranging from 4 weeks to 4 years were studied. A statistical significant HRQoL/HS improvement was reached in 93% of the studies. Nevertheless, the Minimal Important Difference (MID) was reached in 70,6% of the studies considering the difference between baseline and end of the study, and in 50% when comparing active treatment and placebo. Conclusions The data coming from the review support the efficacy of long acting bronchodilators in improving HRQoL/HS of COPD patients. Further research evaluating HRQoL/HS as primary outcome and according to guidelines on Patient Reported Outcomes is needed

Allergic rhinitis: Current options and future perspectives

PURPOSE OF REVIEW: Allergic rhinitis due its high prevalence and burden needs to be properly treated. The disease's clinical features impose well tolerated drugs usable for long-term treatment. Nowadays, second-generation antihistamines and inhaled steroids represent the milestone of rhinitis therapy. The aim of the present review is to provide an update on allergic rhinitis treatment. A particular attention has been deserved to clinical trials, published in the last year that assess the efficacy and safety of new formulation of available drugs or new molecules. RECENT FINDINGS: Available and new drugs under investigation seem able to control rhinitis symptoms without a significant patient's burden. The challenge for the next years will be to improve treatment adherence rather than to introduce new drugs. SUMMARY: Allergic Rhinitis and its Impact on Asthma guidelines have brought attention to allergic rhinitis and its impact on asthma, but have also proposed a new classification in terms of symptoms severity and persistence useful for tailoring treatment on patients' phenotypes. Their further dissemination is needed; furthermore, they represent a cornerstone for the scientific community through a continuous update on relevant issues such as rhinitis phenotypes, disease management on the basis of new treatments, clinical trials transferability in real life, and allergic rhinitis management in public health programs. \uc2\ua9 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins
