Pulmonary veno-occlusive disease (PVOD) is defined by specific pathologic changes of the pulmonary veins. A definite diagnosis of PVOD thus requires a lung biopsy or pathologic examination of pulmonary explants or postmortem lung samples. However, lung biopsy is hazardous in patients with severe pulmonary hypertension, and there is a need for noninvasive(More)
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)
Monoclonal antibodies targeted against the immune checkpoint molecules CTLA-4 and PD-1 have recently obtained approval for the treatment of metastatic melanoma and advanced/refractory non small-cell lung cancers. Therefore, their use will not be limited anymore to selected hospitals involved in clinical trials. Indeed, they will be routinely prescribed in(More)
OBJECTIVE To describe the response to first-line immunosuppressive therapy with or without pulmonary vasodilators in pulmonary arterial hypertension (PAH) associated with systemic lupus erythematosus (SLE) or mixed connective tissue disease (MCTD). METHODS Twenty-three consecutive patients with SLE- or MCTD-associated PAH treated with first-line(More)
OBJECTIVES To examine baseline characteristics and outcome, and to determine variables affecting survival in patients with pulmonary arterial hypertension (PAH) associated with HIV infection (PAH-HIV) in the modern era of highly-active antiretroviral therapy (HAART) and specific PAH therapy. DESIGN Retrospective review of data from PAH-HIV patients(More)
RATIONALE Portopulmonary hypertension (PoPH) can be defined as elevation of pulmonary arterial pressure and pulmonary vascular resistance in the setting of portal hypertension. Survival results in PoPH are contrasting, and prognostic factors need to be identified. OBJECTIVES To analyze long-term survival in a large cohort of patients with PoPH with the(More)
RATIONALE Pulmonary arterial hypertension (PAH) related to systemic sclerosis (SSc) has a poorer prognosis compared with other forms of PAH for reasons that remain unexplained. OBJECTIVES To identify risk factors of mortality in a well-characterized cohort of patients with PAH related to systemic sclerosis (SSc-PAH). METHODS Seventy-six consecutive(More)
Two pulmonary vascular disorders can occur in liver disease and/or portal hypertension: the hepatopulmonary syndrome (HPS), which is characterized by intrapulmonary vascular dilatations, and portopulmonary hypertension (POPH), in which pulmonary vascular resistance is elevated. POPH and HPS are characterized by distinct pulmonary microvascular remodelling,(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)
