A proportion of patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) do not achieve treatment goals or experience side effects on their current therapy. In such cases, switching patients to a new drug while discontinuing the first may be a viable and appropriate treatment option. CAPTURE was designed to investigate how physicians manage the switching of patients to riociguat in real-world clinical practice. Observations from the study were used to assess whether recommendations in the riociguat prescribing information are reflected in clinical practice.
To evaluate the influence of riociguat on World Health Organization functional class (WHO FC), 6-min walk distance (6MWD), right heart remodeling, and right ventricular-pulmonary arterial (RV-PA) coupling in patients with idiopathic pulmonary arterial hypertension (IPAH) who are treatment-naïve or who have failed to achieve treatment goals with sildenafil therapy.
Pulmonary emphysema is a major manifestation of chronic obstructive pulmonary disease (COPD), which is characterized by progressive destruction of alveolar parenchyma with persistent inflammation of the small airways. Such destruction in the distal respiratory tract is irreversible and irreparable. All-trans-retinoic acid was suggested as a novel therapy for regeneration of lost alveoli in emphysema. However, profound discrepancies were evident between studies. At present, no effective therapeutic options are available that allow for the regeneration of lost alveoli in emphysematous human lungs. Recently, some reports on rodent’s models have suggested the beneficial effects of various growth factors toward alveolar maintenance and repair processes.
IgG4-related disease (IgG4RD) is a recently recognized disease entity. Differentiating IgG4RD from plasma cell type Castleman’s disease (PCD) is important but also difficult using only pathological findings. In addition, little is known about the association between these two diseases with diffuse parenchymal lung involvement.
The purpose of this study was to investigate the potential value of certain biomarkers in predicting the presence of malignant pleural mesothelioma (MPM) in individuals environmentally exposed to asbestos.
Since the first description of pulmonary circulation in the 16th century, the knowledge of the complex interaction between the heart and lungs has greatly improved. Hypoxemia plays a classical role in the development of complications such as pulmonary hypertension and right ventricle (RV) dysfunction in patients presenting with chronic obstructive pulmonary disease (COPD). However, more recent results have revealed the presence of RV vascular structural and functional changes even in patients with mild COPD, without hypoxemia or pulmonary hypertension at rest. Compared to the left ventricle, the anatomy of the RV is unique and complex, which makes its assessment more difficult during routine exams. Therefore, it is common that very little attention is paid to its study. In this article, the physiological aspects of pulmonary circulation and the RV, as well as their impairment in COPD patients, are presented. In addition, important aspects of the recommendations for RV assessment using echocardiography are approached and studies that used other complementary exams to evaluate RV structure and function are revisited. Finally, the findings of studies that assessed the impact of RV dysfunction in the prognosis of patients with COPD are described.
There is a strong association between cystic fibrosis and malnutrition, mainly because of the higher energy needs combined with lower intake. There is also a well-established correlation between good nutritional status and better lung function. To date, however, there are no studies examining nutritional status in childhood and adult lung function. To respond to this need, this innovative study explored the long-term correlations between nutritional status in childhood and lung function in adulthood for the same patient population.
This study aimed to characterize, for the first time in Spain, the type of asbestos fibres (AF) in the lungs of exposed and non-exposed populations.
The burden of childhood asthma and its risk factors is an important but neglected public health challenge in Latin America. We investigated the association between allergic symptoms and dietary intake in children from this region.
Adherence to a Mediterranean diet pattern may be associated with lower asthma prevalence in children. We sought to corroborate these findings in Peruvian children.
