Psychiatric Disorders in Patients with Chronic Obstructive Pulmonary Disease: Clinical Significance and Treatment Strategies.

Chronic obstructive pulmonary disease (COPD) is a debilitating lung disease characterized by chronic airflow limitation and persistent respiratory symptoms. It is a major cause of morbidity and mortality worldwide, significantly impacting healthcare systems with considerable socioeconomic consequences. The main risk factors include exposure to tobacco smoke, environmental pollutants, occupational dust, and genetic factors such as alpha-1 antitrypsin deficiency.

Chronic obstructive pulmonary disease's eosinophilic phenotype: Clinical characteristics, biomarkers and biotherapy.

COPD is a chronic, heterogeneous inflammatory disorder of the airways with persistent and poorly reversible airflow limitation, causing symptoms such as cough, shortness of breath, and sputum production. Despite optimal treatment, some patients remain symptomatic due to the disease's heterogeneity, manifesting in various phenotypes. One notable phenotype involves eosinophilic inflammation, with a variable prevalence.

A Comparison of GOLD and STAR Severity Stages in Individuals With COPD Undergoing Pulmonary Rehabilitation.

Exploring the Impact of Inhaled Corticosteroids on Endothelial Function in Chronic Obstructive Pulmonary Disease Patients Undergoing Pulmonary Rehabilitation.

: Chronic obstructive pulmonary disease (COPD) is associated with subclinical atherosclerosis and endothelial dysfunction, which can be assessed non-invasively through flow-mediated dilation (FMD). In this study, we evaluated the potential impact of inhaled corticosteroid (ICS) therapy on FMD of COPD patients undergoing pulmonary rehabilitation (PR). : Medical records of COPD patients undergoing FMD assessment upon admission to our Pulmonary Rehabilitation Unit were reviewed in this retrospective post hoc analysis.

Reducing the risk of death - a possible outcome in COPD patients.

Introduction: COPD is a leading cause of global mortality, particularly under-recognized and under-diagnosed. In 2020, it was the sixth leading cause of death in the US and has contributed to 4.72% of all-cause mortality (ACM) according to the Global Burden of Disease Study 2017.

Endotyping Chronic Respiratory Diseases: T2 Inflammation in the United Airways Model.

Over the past 15 years, the paradigm of viewing the upper and lower airways as a unified system has progressively shifted the approach to chronic respiratory diseases (CRDs). As the global prevalence of CRDs continues to increase, it becomes evident that acknowledging the presence of airway pathology as an integrated entity could profoundly impact healthcare resource allocation and guide the implementation of pharmacological and rehabilitation strategies. In the era of precision medicine, endotyping has emerged as another novel approach to CRDs, whereby pathologies are categorized into distinct subtypes based on specific molecular mechanisms.

A clinician's guide to single vs multiple inhaler therapy for COPD.

Introduction: In the management of chronic obstructive pulmonary disease (COPD), inhalation therapy plays a pivotal role. However, clinicians often face the dilemma of choosing between single and multiple inhaler therapies for their patients. This choice is critical because it can affect treatment efficacy, patient adherence, and overall disease management.

Exploring novel perspectives on eosinophilic inflammation in severe asthma.

Two recent articles by the same research group documented that patients with severe eosinophilic asthma exhibit an increased proportion of a subtype of eosinophils, namely CD62L inflammatory eosinophils (iEos) and identified an intriguing correlation between such iEos and asthma control scores. Moreover, CD62L iEos were reduced after treatment with the anti-IL-5 monoclonal antibody mepolizumab. In the future, we believe that eosinophil subtypes could represent a useful biomarker in severe eosinophilic asthma, helping clinicians characterize patient endotypes and monitoring the response to biological drugs.

Quality of life and work functionality in severe asthma patients: the impact of biological therapies.

Background: Severe asthma can cause poor health status, poor health-related quality of life (HRQoL) and an impaired functioning at work. However, to date, limited data are available on the impact of the biological therapies on such outcomes. Therefore, aim of the present study was to prospectively assess the clinical, quality of life and work functionality issues in severe asthma patients both at baseline and after 6 months of biological therapies and determine which individual, pathological and occupational factors can influence such parameters.

Impact of biologics on lung hyperinflation in patients with severe asthma.

Background: In asthma, inflammation affects both the proximal and distal airways and can cause significant hyperinflation, which is thought to be a major cause of dyspnea.

Methods: This is a retrospective observational study evaluating the effect of three months of treatment with different biologic drugs (benralizumab, dupilumab and omalizumab) on pulmonary hyperinflation in a cohort of patients with severe asthma already receiving regular triple inhaled therapy. Changes in RV, RV/TLC ratio, FRC and FRC/TLC ratio were the primary efficacy measures.

The Role of High-Flow Nasal Cannula Oxygen Therapy in Exercise Testing and Pulmonary Rehabilitation: A Review of the Current Literature.

High-flow nasal cannula (HFNC) has recently emerged as a crucial therapeutic strategy for hypoxemic patients both in acute and chronic settings. Indeed, HFNC therapy is able to deliver higher fractions of inspired oxygen (FiO) with a heated and humidified gas flow ranging from 20 up to 60 L per minute, in a more comfortable way for the patient in comparison with Conventional Oxygen Therapy (COT). In fact, the flow keeps the epithelium of the airways adequately moisturized, thus positively affecting the mucus clearance.

Cardiovascular Risk Associated with Alpha-1 Antitrypsin Deficiency (AATD) Genotypes: A Meta-Analysis with Meta-Regressions.

Background: Alpha-1 antitrypsin deficiency (AATD) can result in severe liver and respiratory disorders. The uninhibited elastase activity on the elastic tissue of arterial walls suggests that AATD may also impact vascular health. Thus, we performed a meta-analysis of the studies evaluating cardiovascular risk in individuals with AATD and non-AATD controls.

The Clinical Application of Established and Emerging Biomarkers for Chronic Respiratory Diseases.

Biomarkers are indicators of a pathological or physiological state, and they are essential for facilitating the diagnosis of a subclinical condition, understanding the origin or progression of a disease, stratifying the risk, and assessing the response to a specific therapeutic approach [...

Flow-mediated dilation as a marker of endothelial dysfunction in pulmonary diseases: A narrative review.

The endothelium is an active and crucial component of vessels and produces several key regulatory factors for the homeostasis of the entire organism. Endothelial function can be investigated invasively or non-invasively, both in the coronary and peripheral circulation. A widely accepted method for the assessment of endothelial function is measurement of flow-mediated dilation (FMD), which evaluates the vascular response to changes in blood flow.

Clinical Applications of Nasal Nitric Oxide in Allergic Rhinitis: A Review of the Literature.

Allergic rhinitis, a common allergic disease affecting a significant number of individuals worldwide, is observed in 25% of children and 40% of adults, with its highest occurrence between the ages of 20 and 40. Its pathogenesis, like other allergic diseases, involves innate and adaptive immune responses, characterized by immunologic hypersensitivity to environmental substances. This response is mediated by type 2 immunity.

A Multidisciplinary Approach for Type 2 Allergic Diseases: What Do Biologics Teach Us?

Patients with atopic/allergic disorders, including atopic dermatitis (AD), allergic rhino-conjunctivitis (AR), chronic rhinosinusitis with/without nasal polyps (CRSwNP/CRSsNP), bronchial asthma, food allergy, and eosinophilic esophagitis (EoE), often share a common genetic background, a type Th2 polarized immune response, and several environmental factors [...

Pulmonary rehabilitation and endothelial function in patients with chronic obstructive pulmonary disease: A prospective cohort study.

Background: Chronic obstructive pulmonary disease (COPD) is associated with subclinical atherosclerosis and endothelial dysfunction, thereby leading to increased cardiovascular risk. In the present study, we evaluated the changes in endothelium-dependent flow-mediated dilation (FMD) in a cohort of severe COPD patients undergoing pulmonary rehabilitation.

Methods: Consecutive COPD patients referred to our Pulmonary Rehabilitation Unit were screened for inclusion.

Pharmacotherapies in Older Adults with COPD: Challenges and Opportunities.

Older adults have a higher prevalence of chronic obstructive pulmonary disease (COPD), which will likely increase substantially in the coming decades owing to aging populations and increased long-term exposure to risk factors for this disease. COPD in older adults is characterized by low-grade chronic systemic inflammation, known as inflamm-aging. It contributes substantially to age-associated pulmonary changes that are clinically expressed by reduced lung function, poor health status, and limitations in activities of daily living.
