Augmentation of the effects of vasoactive intestinal peptide aerosol on pulmonary hypertension via coapplication of a neutral endopeptidase 24.11 inhibitor.

A deficiency of the pulmonary vasodilative vasoactive intestinal peptide (VIP) has been suggested to be involved in the pathophysiology of pulmonary hypertension (PH). Supplementation of VIP as an aerosol is hampered by the fact that it is rapidly inactivated by neutral endopeptidases (NEP) located on the lung surface. Coapplication of thiorphan, an NEP 24.

Riociguat for the treatment of pulmonary hypertension.

Introduction: Pulmonary arterial hypertension (PAH) is still an incurable disease with high mortality despite recent treatment advances. Chronic thromboembolic pulmonary hypertension (CTEPH) is a specific form of pulmonary hypertension due to thromboembolic occlusion of pulmonary arteries. Although 50 - 60% of the CTEPH patients can be cured via pulmonary endarterectomy (PEA), a significant portion is inoperable.

Haemodynamic changes in pulmonary hypertension in patients with interstitial lung disease treated with PDE-5 inhibitors.

Background And Objective: Interstitial lung diseases (ILD) are often associated with pulmonary hypertension (PH). This study aimed to evaluate the therapeutic benefit of phosphodiesterase-5 (PDE-5) inhibitors in pulmonary hypertension secondary to ILD.

Methods: Patients with ILD and PH were treated with sildenafil or tadalafil.

The Munich-LTX-Score: predictor for survival after lung transplantation.

Background: The purpose of this study was to create a prognostic score calculated one yr after LTX based on post-transplant factors inclusive of donor and recipient characteristics that could be used to predict long-term survival in patients after lung transplantation (LTX).

Methods: Uni- and multivariate analysis in 206 consecutive LTX patients identified independent risk factors for post-transplant mortality and onset of bronchiolitis obliterans syndrome. Munich-LTX-Score is devised by summing up each identified risk factor.

Is sirolimus a therapeutic option for patients with progressive pulmonary lymphangioleiomyomatosis?

Background: Lymphangioleiomyomatosis (LAM) is a rare lung disease characterised by progressive airflow obstruction. No effective medical treatment is available but therapy with sirolimus has shown some promise. The aim of this observational study was to evaluate sirolimus in progressive LAM.

Pulmonary hypertension: role of combination therapy.

Over the past decade different effective treatment options for use in pulmonary arterial hypertension (PAH) have been developed. Due to multiple pathophysiological pathways in PAH and unsatisfactory overall results with the use of monotherapy in a substantial number of PAH patients, there is a pharmacological rationale for combination therapy. The currently approved substances target the prostacyclin, the endothelin and the NO (nitric oxide) -pathways.

Potential functional and survival benefit of double over single lung transplantation for selected patients with idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a frequent indication for lung transplantation (LTX) with pulmonary hypertension (PH) negatively affecting outcome. The optimal procedure type remains a debated topic. The aim of this study was to evaluate the impact of pretransplant PH in IPF patients.

Preserved pulmonary vasodilative properties of aerosolized brain natriuretic peptide.

Introduction: Inhalation of vasoactive substances is an effective treatment of pulmonary hypertension. The B-type natriuretic peptide (BNP) leads to relaxation of smooth muscle cells, caused by an increased formation of cyclic guanosine monophosphate (cGMP). The biologic activity of BNP using an inhalative approach has not been addressed.

Inhalation of endothelin receptor blockers in pulmonary hypertension.

Endothelin 1 (ET-1) is a potent pulmonary vasoconstrictor and mediator of lung diseases. Antagonism of the ET-1-mediated effects has become an important therapeutic approach. ET-1 (A and B) receptors are differentially distributed in the lung vasculature.
