RATIONALE Platelet-derived growth factor (PDGF) promotes the proliferation and migration of pulmonary artery smooth muscle cells (PASMCs), and may play a role in the progression of pulmonary arterial hypertension (PAH), a condition characterized by proliferation of PASMCs resulting in the obstruction of small pulmonary arteries. OBJECTIVES To analyze the(More)
This study aims to describe the haemodynamic and survival characteristics of patients with pulmonary hypertension in the recently individualised syndrome of combined pulmonary fibrosis and emphysema. A retrospective multicentre study was conducted in 40 patients (38 males; age 68+/-9 yrs; 39 smokers) with combined pulmonary fibrosis and emphysema, and(More)
The aim of the present study was to describe a large cohort of fenfluramine-associated pulmonary arterial hypertension (fen-PAH) and its possible prognostic markers. The records of all patients with a diagnosis of fen-PAH evaluated at the present authors' centre from 1986-2004 were retrospectively studied. Baseline clinical and haemodynamic data were(More)
The aim of this study was to examine the causes and outcomes of hospitalisation in patients with pulmonary arterial hypertension (PAH). 205 consecutive hospitalisations occurring between 2000 and 2009 in 90 PAH patients were studied. The leading causes for hospitalisation were right heart failure (RHF; 56%), infection (16%) and bleeding disorders (8%). For(More)
N-terminal pro-brain natriuretic peptide (NT-proBNP) is a marker of neurohormonal activation that is useful in the diagnosis and prognosis of various forms of pulmonary arterial hypertension (PAH). We sought to characterise and compare NT-proBNP in a cohort of PAH related to systemic sclerosis (PAH-SSc) and idiopathic PAH (IPAH) patients. NT-proBNP levels,(More)
BACKGROUND End-stage chronic respiratory diseases (CRD) have systemic consequences, such as weight loss and susceptibility to infection. However the mechanisms of such dysfunctions are as yet poorly explained. We hypothesized that the genes putatively involved in these mechanisms would emerge from a systematic analysis of blood mRNA profiles from(More)
Data on treatment of patients with portopulmonary hypertension (PoPH) are limited, as they are usually excluded from randomised controlled trials with pulmonary arterial hypertension (PAH)-specific therapies. This study investigated the short- and long-term efficacy/safety of bosentan in these patients, as well as its pharmacokinetics. All 34 consecutive(More)
Bosentan has proven 4-month efficacy in patients with HIV-associated pulmonary arterial hypertension (PAH-HIV). Herein, the long-term outcome of unselected PAH-HIV patients treated with first-line bosentan is described. Data for 59 consecutive World Health Organization (WHO) functional class II-IV PAH-HIV patients treated with first-line bosentan between(More)
Common bile duct ligation (CBDL) induces biliary cirrhosis and pulmonary vasodilatation. We tested whether CBDL ameliorates monocrotaline (MCT)-induced pulmonary hypertension (PH) in rats. Five groups of rats were studied: controls; rats dosed with MCT (60 mg.kg(-1) subcutaneously); CBDL; rats dosed with MCT followed by CBDL on day 7; and rats dosed with(More)
