Indacaterol for the treatment of chronic obstructive pulmonary disease.

The need for a rapid onset of action and a long duration of the broncholytic effect is the likely reason for the development of new long-acting β2-agonists (LABAs) that are fast acting and have true 24 h duration of action. Indacaterol is the archetype of once-daily LABAs and already marketed as a maintenance therapy in patients with moderate to severe chronic obstructive pulmonary disease (COPD).

Areas covered: Meta-analyses of published data or pooled analyses of primary data provide good insight into the clinical role of indacaterol in COPD.

Expert opinion: The choice of the once-daily bronchodilator to start treatment in a patient with COPD mainly depends on the outcome of interest. Indacaterol is more effective than tiotropium if we consider symptoms or health-related quality of life as the primary outcome. Moreover, in symptomatic patient indacaterol should be preferred to tiotropium because of its rapid onset of action. By contrast, tiotropium appears to be more effective than indacaterol if exacerbations are the expected primary outcome.

However, as indacaterol/glycopyrronium fixed-dose combination (QVA149) shows superior efficacy compared to glycopyrronium and tiotropium in patients with moderate to severe COPD, a fundamental question regarding the use of indacaterol that requires clarification is whether it is preferable to start immediately with QVA149 rather than using indacaterol alone.

Overview of the prevalence, impact, and management of depression and anxiety in chronic obstructive pulmonary disease.

More than one third of individuals with chronic obstructive pulmonary disease (COPD) experience comorbid symptoms of depression and anxiety. This review aims to provide an overview of the burden of depression and anxiety in those with COPD and to outline the contemporary advances and challenges in the management of depression and anxiety in COPD.

Symptoms of depression and anxiety in COPD lead to worse health outcomes, including impaired health-related quality of life and increased mortality risk. Depression and anxiety also increase health care utilization rates and costs. Although the quality of the data varies considerably, the cumulative evidence shows that complex interventions consisting of pulmonary rehabilitation interventions with or without psychological components improve symptoms of depression and anxiety in COPD. Cognitive behavioral therapy is also an effective intervention for managing depression in COPD, but treatment effects are small. Cognitive behavioral therapy could potentially lead to greater benefits in depression and anxiety in people with COPD if embedded in multidisciplinary collaborative care frameworks, but this hypothesis has not yet been empirically assessed. Mindfulness-based treatments are an alternative option for the management of depression and anxiety in people with long-term conditions, but their efficacy is unproven in COPD.

Beyond pulmonary rehabilitation, the evidence about optimal approaches for managing depression and anxiety in COPD remains unclear and largely speculative. Future research to evaluate the effectiveness of novel and integrated care approaches for the management of depression and anxiety in COPD is warranted.

Feasibility of cytological diagnosis of sarcoidosis with endobronchial US-guided transbronchial aspiration.

CONCLUSIONS: Cytological evaluation of the EBUS-TBNA specimens had higher sensitivity than histological evaluation alone for intrathoracic lymphadenopathy due to sarcoidosis. It should be recognized, however, that up to 6% of patients with thoracic malignancy may have sarcoid reaction in non-metastatic lymph nodes.

Review of IPF diagnosis and management recommendations in Europe.

Authors: Xaubet A, Behr J, Bendstrup E, Cottin V, Hirani N, Kähler C, Sköld M Abstract Increased knowledge of Idiopathic Pulmonary Fibrosis (IPF) led to the development of evidence-based diagnosis and treatment guidelines. A 2011 update of the American Thoracic Society and the European Respiratory Society, together with the Japanese Respiratory Society ( JRS) and Latin AmericanThoracic Association (ALAT) provided new guidance on the diagnosis and treatment of IPF. Although the 2011 statement was a major advance, the application of guideline recommendations has identified limitations.The guidelines focus primarily on 'definite' IPF, most often diagnosed from typical High-Resolution Computed Tomography (HRCT) appearances.The definition of 'probable' and 'possible' IPF is an advance...

A meta-analysis of complications and mortality of extracorporeal membrane oxygenation.

CONCLUSIONS: Even with conditions usually associated with a high chance of death, almost 50% of patients receiving ECMO survive up to discharge. Complications are frequent and most often comprise renal failure, pneumonia or sepsis, and bleeding. PMID: 23944202 [PubMed - indexed for MEDLINE] (Source: Critical Care and Resuscitation)
