Comparison of MRI and VQ-SPECT as a Screening Test for Patients With Suspected CTEPH: CHANGE-MRI Study Design and Rationale

2020

The diagnostic strategy for chronic thromboembolic pulmonary hypertension (CTEPH) is composed of two components required for a diagnosis of CTEPH: the presence of chronic pulmonary embolism and an elevated pulmonary artery pressure. The current guidelines require that ventilation–perfusion single-photon emission computed tomography (VQ-SPECT) is used for the first step diagnosis of chronic pulmonary embolism. However, VQ-SPECT exposes patients to ionizing radiation in a radiation sensitive population. The prospective, multicenter, comparative phase III diagnostic trial CTEPH diagnosis Europe - MRI (CHANGE-MRI, ClinicalTrials.gov identifier NCT02791282) aims to demonstrate whether functional…

Alternative mechanisms for tiotropium

2009

Tiotropium is commonly used in the treatment of chronic obstructive pulmonary disease. Although largely considered to be a long-acting bronchodilator, its demonstrated efficacy in reducing the frequency of exacerbations and preliminary evidence from early studies indicating that it might slow the rate of decline in lung function suggested mechanisms of action in addition to simple bronchodilation. This hypothesis was examined in the recently published UPLIFT study and, although spirometric and other clinical benefits of tiotropium treatment extended to four years, the rate of decline in lung function did not appear to be reduced by the addition of tiotropium in this study. This article summ…

S2K-Leitlinie zur Diagnostik und Therapie der idiopathischen Lungenfibrose

2013

Die idiopathische pulmonale Fibrose (IPF) ist eine schwerwiegende und in der Regel zum Tod fuhrende Erkrankung, die bisher nur unzureichend behandelt werden kann. Empfehlungen zur Diagnostik und Therapie wurden erstmals im ATS-ERS-Statement im Jahr 2000 publiziert 1 . Seither haben sich die diagnostischen Standards geandert und es liegen zahlreiche Therapiestudien zu diesem Krankheitsbild vor, die es erforderlich machten, die bestehenden Empfehlungen zu uberarbeiten und eine wissenschaftlich begrundete Leitlinie zu erstellen. Diese wurde von einer internationalen Expertengruppe in den Jahren 2006 – 2010 erarbeitet und publiziert 2 . Die folgenden Ausfuhrungen beinhalten eine Ubersetzung wes…
