BACKGROUND Patients with chronic obstructive pulmonary disease (COPD) have few options for treatment. The efficacy and safety of the phosphodiesterase-4 inhibitor roflumilast have been investigated in studies of patients with moderate-to-severe COPD, but not in those concomitantly treated with longacting inhaled bronchodilators. The effect of roflumilast on(More)
AIM To determine the prevalence and analyze the most relevant clinical characteristics of three clinical phenotypes of COPD: emphysema (type 1), chronic bronchitis (type 2) or COPD-asthma (type 3). METHOD Observational, multicenter study performed with 331 COPD patients recruited in pulmonology outpatient services. The stratification in three phenotypes(More)
INTRODUCTION Chronic obstructive pulmonary disease (COPD) patients present a high prevalence of cardiovascular disease. This excess of comorbidity could be related to a common pathogenic mechanism, but it could also be explained by the existence of common risk factors. The objective of this study was to determine whether COPD patients present greater(More)
BACKGROUND Patients with the obesity-hypoventilation syndrome (OHS) benefit from non-invasive ventilatory support. We assessed the long-term physiopathological response to 12-months of nocturnal ventilatory assistance at home with bi-level positive airway pressure (BiPAP) via nasal mask in patients with this disease. METHODS A series of 13 non-consecutive(More)
OBJECTIVE Cardiovascular disease is a common cause of death in patients with chronic obstructive pulmonary disease (COPD). It is not clear whether the high cardiovascular comorbidity is due to an increase in traditional risk factors or whether, in contrast, COPD can be considered an independent risk factor. The aim of this study was to analyze the(More)
To investigate pulmonary function abnormalities in Parkinson's disease (PD), we obtained maximal inspiratory and expiratory flow-volume curves in 63 patients (59 under treatment) with different stages of the disease, not filtered for respiratory symptoms. PD severity was evaluated by the Unified PD Rating Scale, the Webster's scale, and Hoehn and Yahr(More)
Previous studies have described that there are different types of disease in patients with established chronic obstructive pulmonary disease (COPD) with different clinical course and functional responses. The aim of this study was to evaluate if the presence of low transfer factor (LTF) values can predict the effectiveness of bronchodilator therapy, and to(More)
Chronic obstructive pulmonary disease (COPD) is associated with impaired gas mixing and increased dead space, but little is known about the effect of improving alveolar gas sample by complete correction of dead space in an attempt to significantly improve the final result of transfer factor compared with standard guidelines of the European Respiratory(More)
OBJECTIVES To investigate pulmonary function abnormalities in essential tremor. METHODS We obtained maximal inspiratory and expiratory flow-volume curves in 41 unselected patients with essential tremor (14 males, 27 females, age 61.7 +/- 2.14 years). Severity of essential tremor was evaluated using the Fahn, Tolosa and Marin clinical scale. RESULTS(More)
