The precision medicine strategy to treat COPD pulmonary traits in clinical practice: The role of N-acetylcysteine.

Chronic obstructive pulmonary disease (COPD) is a progressive lung condition and a leading cause of physical decline and death. COPD prevalence is expected to increase steadily in the coming years, and as a result, the healthcare and social burden of this condition will intensify. In this scenario, a patient-centric approach, the treatable trait (TT) strategy, based on the identification of traits that are clinically relevant, identifiable, monitorable and treatable, has emerged.

Expression of human Interferon Regulatory Factor 3 (IRF-3) in alveolar macrophages relates to clinical and functional traits in COPD.

Introduction: Chronic obstructive pulmonary disease (COPD) is a frequent cause of morbidity and mortality. Dysregulated and enhanced immune-inflammatory responses have been described in COPD. Recent data showed impaired immune responses and, in particular, of interferon (IFNs) signaling pathway in these patients.

Long-term inhaled corticosteroid treatment in patients with chronic obstructive pulmonary disease, cardiovascular disease, and a recent hospitalised exacerbation: The ICSLIFE pragmatic, randomised controlled study.

Introduction: Patients with chronic obstructive pulmonary disease (COPD) frequently have cardiovascular comorbidities, increasing the risk of hospitalised COPD exacerbations (H-ECOPDs) or death. This pragmatic study examined the effects of adding an inhaled corticosteroid (ICS) to long-acting bronchodilator(s) (LABDs) in patients with COPD and cardiac comorbidities who had a recent H-ECOPD.

Methods: Patients >60 years of age with COPD and ≥1 cardiac comorbidity, within 6 months after discharge following an H-ECOPD, were randomised to receive LABD(s) with or without ICS, and were followed for 1 year.

N-acetylcysteine Treatment in Chronic Obstructive Pulmonary Disease (COPD) and Chronic Bronchitis/Pre-COPD: Distinct Meta-analyses.

Introduction: N-acetylcysteine (NAC) is a mucolytic agent with antioxidant properties. Oxidative stress is a key pathogenic mechanism in chronic respiratory conditions such as COPD and chronic bronchitis (CB). In these meta-analyses we investigated the efficacy of NAC in subjects with COPD or CB, the latter being a potential pre-COPD condition (CB/pre-COPD).
