Pulmonary hypertension (PH) is a chronic cardiopulmonary disorder that if left untreated, progresses rapidly and is ultimately fatal. The World Health Organization (WHO) has classified PH into 5 distinct groups according to pathophysiology, hemodynamic characteristics, and clinical presentation. Dysfunction in the nitric oxide (NO) pathway plays a key role in the pulmonary hypertension disease process, including in WHO Groups 2 and 3 PH. PH is associated with endothelial dysfunction, impaired synthesis of NO, and insufficient stimulation of the NO-soluble guanylate cyclase (sGC)-cyclic guanosine monophosphate (cGMP) pathway, which reduces cGMP production...

Patients with pulmonary arterial hypertension (PAH) who do not have an adequate response to therapy with phosphodiesterase-5 inhibitors (PDE-5i) may have insufficient synthesis of cyclic guanosine monophosphate (cGMP). These patients may respond to a direct soluble guanylate cyclase (sGC) stimulator such as riociguat. RESPITE (NCT02007629) was an open-label, multicenter, uncontrolled, single-arm phase 3b study of riociguat in patients with PAH who demonstrated an insufficient response to treatment with PDE-5i...

Advances in the treatment of idiopathic interstitial pneumonia (IIP) represent an urgent, unmet medical need for patients with this category of diffuse parenchymal lung disease. IIPs involve varying combinations of fibrosis and inflammation of unknown cause and may be associated with pulmonary hypertension (PH). When it occurs, PH is associated with higher oxygen needs, greater functional impairment, and increased mortality. However, whether or when PH is a maladaptive versus adaptive phenomenon remains to be determined...

In clinical trials of treatments for pulmonary arterial hypertension (PAH), objective measures, such as 6-min walking distance (6MWD) are limited in their ability to characterize the impact of PAH therapy from a patient's perspective. Few clinical studies have evaluated the primary effects of pharmacologic treatment on patient-reported outcomes, such as symptoms, health-related quality of life (HRQoL), and productivity. MOTION (NCT02191137) is a prospective, multicenter, single-arm, open-label, phase 4 trial designed to assess whether riociguat monotherapy will improve patient-reported outcomes in patients with PAH in the United States who are not currently on treatment...

: RISE-SSc is a randomized, double-blind, placebo-controlled phase 2 study investigating the efficacy and safety of riociguat in patients with diffuse cutaneous systemic sclerosis (dcSSc). Based on positive results from riociguat trials in patients with pulmonary hypertension and chronic thromboembolic pulmonary hypertension in combination with the known antiproliferative and antifibrotic effects seen in animal models, patients with SSc may benefit from treatment with riociguat. Patients with SSc meeting the ACR/EULAR systemic sclerosis classification criteria with diffuse cutaneous SSc (dcSSc) subset per LeRoy criteria, and a disease duration of less than or equal to 18 months will be randomized to placebo or riociguat 0...

Exertional Dyspnea is a troublesome symptom in chronic obstructive pulmonary disease (COPD) even after optimal therapy, which is a physiological and perceptional burden to limit their activities. Non-invasive ventilation (NIV) might provide rescue therapy for this population to relieve exertional dyspnea. This was a randomized crossover study in 18 patients with stable severe COPD. Exertional dyspnea was induced with maximal symptom-limited incremental cycle exercise. Then the patients would randomly receive oxygen or NIV plus oxygen therapy...

BACKGROUND: The diagnosis of asthma in children is challenging and relies on a combination of clinical factors and biomarkers including methacholine challenge, lung function, bronchodilator responsiveness, and presence of airway inflammation. No single test is diagnostic. We sought to identify a pattern of inflammatory biomarkers that was unique to asthma using a targeted metabolomics approach combined with data science methods. METHODS: We conducted a nested case-control study of 100 children living in a peri-urban community in Lima, Peru...

BACKGROUND: Obesity worsens asthma control partly through enhanced airway neutrophilia, altered lung mechanics and comorbidities, including obstructive sleep apnea syndrome, gastroesophageal reflux disease and depression. Although controversial, obesity may also cause poorer outcomes in acute asthma. IL-17 is associated with neutrophilic inflammation, steroid resistance and severe asthma, but its importance in the association between asthma and obesity is unknown. OBJECTIVE: To investigate the role of IL-17 in obese asthma in both acute and stable settings...

BACKGROUND: The complex interaction between pulmonary function, cardiac function and adverse cardiovascular events has only been partially described. We sought to describe the association between pulmonary function with left heart structure and function, all-cause mortality and incident cardiovascular hospitalization. METHODS: This study is a retrospective analysis of patients evaluated in a single tertiary care medical center. We used multivariable linear regression analyses to examine the relationship between FVC and FEV1 with left ventricular ejection fraction (LVEF), left ventricular internal dimension in systole and diastole (LVIDS, LVIDD) and left atrial diameter, adjusting for baseline characteristics, right ventricular function and lung hyperinflation...

BACKGROUND: Almost all international guidelines recommend corticosteroids for management of exacerbations of chronic obstructive pulmonary disease (COPD), because it leads to improved outcomes of acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Nevertheless, due to its side effects, there are still concerns regarding the use of systemic corticosteroid (SC). Inhaled corticosteroids (IC) can be used as an alternative to SC, while reducing the risk of occurrence of side effects...

BACKGROUND: Azathioprine is a commonly prescribed therapy for connective tissue disease-associated interstitial lung disease (CTD-ILD). Combination therapy that included azathioprine was recently shown to increase the risk of death and hospitalization in patients with idiopathic pulmonary fibrosis. Whether azathioprine increases the risk of adverse outcomes in patients with fibrotic CTD-ILD, including those with CTD-associated usual interstitial pneumonia (UIP), remains unknown. METHODS: A retrospective cohort analysis was performed to determine the combined incidence rate of death, transplant and respiratory hospitalization associated with azathioprine exposure...
