Neglected evidence in idiopathic pulmonary fibrosis and the importance of early diagnosis and treatment.

Related Articles

In idiopathic pulmonary fibrosis (IPF), some facts or concepts based on substantial evidence, whilst implicit for learned subspecialists, have previously been neglected and/or not explicitly formulated or made accessible to a wider audience.

IPF is strongly associated with cigarette smoking and is predominantly a disease of ageing. However, its cause(s) remain elusive and, thus, it is one of the most challenging diseases for the development of novel effective and safe therapies. With the approval of pirfenidone for patients with mild-to-moderate IPF, an earlier diagnosis of IPF is a prerequisite for earlier treatment and, potentially, improvement of the long-term clinical outcome of this progressive and ultimately fatal disease. An earlier diagnosis may be achieved in IPF by promoting thin-slice chest high-resolution computed tomography screening of interstitial lung disease as a "by-product" of large-scale lung cancer screening strategies in smokers, but other techniques, which have been neglected in the past, are now available. Lung auscultation and early identification of "velcro" crackles has been proposed as a key component of early diagnosis of IPF.

An ongoing study is exploring correlations between lung sounds on auscultation obtained using electronic stethoscopes and high-resolution computed tomography patterns.

Pirfenidone: an update on clinical trial data and insights from everyday practice.

Pirfenidone is an orally active, small molecule that inhibits synthesis of profibrotic and inflammatory mediators. It was approved for the treatment of adults with mild-to-moderate idiopathic pulmonary fibrosis in the European Union based on the results of two pivotal phase III, double-blind, randomised, placebo-controlled clinical trials (CAPACITY) demonstrating efficacy and safety, and supported by two Japanese clinical trials (SP2 and SP3).

Currently, there is increasing interest in experience with pirfenidone in patients relating to the real-world setting. Following the publication of the CAPACITY clinical studies, additional analyses have been conducted to provide further support for pirfenidone in clinical practice, including a modified per-protocol analysis of the CAPACITY study population. New data from the RECAP extension study also provided longer term data for pirfenidone and promising continuation rates with treatment.

Pirfenidone is also being evaluated in specialist centre cohorts providing important information on real-world efficacy and safety. Increasing experience with pirfenidone in everyday clinical practice is helping to establish expert guidance on the management of known adverse events, together with practical recommendations, to ensure adherence to treatment so that the possible longer term benefits of pirfenidone treatment in reducing lung function decline can be maximised.

Tissue remodelling in chronic bronchial diseases: from the epithelial to mesenchymal phenotype.

Related Articles
Airway remodelling is a critical feature of chronic bronchial diseases, characterised by aberrant repair of the epithelium and accumulation of fibroblasts, which contribute to extracellular matrix (ECM) deposition resulting in fixed bronchial obstruction. Recently, epithelial-mesenchymal transition (EMT) has been identified as a new source of fibroblasts that could contribute to the remodelling of the airways. This phenomenon consists of the loss of the epithelial phenotype by bronchial epithelial cells and the acquisition of a mesenchymal phenotype. These cells are then able to migrate and secrete ECM molecules. Herein, we review the different types of EMT. We will then focus on the signalling pathways that are involved, such as transforming growth factor-β and Wnt, as well as the more recently described Sonic Hedgehog pathway. Finally, we will highlight the implication of EMT in airway remodelling in specific chronic bronchial pathologies, such as asthma, chronic obstructive pulmonary disease and bronchiolitis obliterans following lung transplantation. Despite the limitations of in vitro models, future studies of EMT in vivo are warranted to shed new light on the pathomechanisms of bronchial obstruction.

Determinants of Noninvasive Ventilation Outcomes during an Episode of Acute Hypercapnic Respiratory Failure in Chronic Obstructive Pulmonary Disease: The Effects of Comorbidities and Causes of Respiratory Failure.

Conclusions. The most important determinants of NIV outcome in COPD patients are the presence of pneumonia and the level of serum albumin as an indicator of the patient nutritional status. PMID: 24563868 [PubMed - in process] (Source: Biomed Res)

Antibiotics for acute bronchitis.

CONCLUSIONS: There is limited evidence to support the use of antibiotics in acute bronchitis. Antibiotics may have a modest beneficial effect in some patients such as frail, elderly people with multimorbidity who may not have been included in trials to date. However, the magnitude of this benefit needs to be considered in the broader context of potential side effects, medicalisation for a self-limiting condition, increased resistance to respiratory pathogens and cost of antibiotic treatment.
