BACKGROUND Chronic thromboembolic pulmonary hypertension (CTEPH) is often a sequel of venous thromboembolism with fatal natural history; however, many cases can be cured by pulmonary endarterectomy. The clinical characteristics and current management of patients enrolled in an international CTEPH registry was investigated. METHODS AND RESULTS The(More)
In 1998, during the Second World Symposium on Pulmonary Hypertension (PH) held in Evian, France, a clinical classification of PH was proposed. The aim of the Evian classification was to individualize different categories sharing similarities in pathophysiological mechanisms, clinical presentation, and therapeutic options. The Evian classification is now(More)
AIMS Dysregulation of the bone morphogenetic protein receptor type 2 (BMPR2) is a hallmark feature that has been described in several forms of pulmonary hypertension. We recently identified the microRNA miR-20a within a highly conserved pathway as a regulator of the expression of BMPR2. To address the pathophysiological relevance of this pathway in vivo, we(More)
BACKGROUND Lymphangioleiomyomatosis is a rare disease of unknown origin that usually leads to progressive deterioration of lung function and eventual death from respiratory failure. It occurs in women of reproductive age and people with tuberous sclerosis. Lung transplantation is a recent therapeutic approach. METHODS We conducted a retrospective study by(More)
Dysregulated expression of bone morphogenetic protein receptor type II (BMPR2) is a pathogenetic hallmark of pulmonary hypertension. Downregulation of BMPR2 protein but not mRNA has been observed in multiple animal models mimicking the disease, indicating a posttranscriptional mechanism of regulation. Because microRNAs (miRNAs) regulate gene expression(More)
A prospective evaluation of 74 human immunodeficiency virus (HIV)-infected patients with cardiopulmonary complaints revealed six patients (8.1 percent) with pulmonary hypertension with elevated right ventricular systolic over right atrial pressure of 58 +/- 8 mm Hg (range, 49 to 66 mm Hg), as documented by Doppler echocardiography. A thromboembolic cause(More)
Due to progress in lung transplantation, post-transplantation osteoporosis becomes an important problem. We determined bone mineral density (BMD) in 74 lung transplantation candidates, among them 24 patients with cysticfibrosis, 16 with chronic obstructive pulmonary disease, 14 with pulmonary fibrosis, and 11 with pulmonary hypertension. The mean T score(More)
Infectious complications are still a significant cause of morbidity and death in solid-organ transplant patients, with significant infection being found in up to two-thirds of these individuals. The risk of infection in the organ transplant patient, particularly of opportunistic infection, is largely determined by 3 factors: the net state of(More)
We present the case of a patient with catheter-related infection caused by Delftia tsuruhatensis, a newly described species closely related to Delftia acidovorans (formerly Comamonas acidovorans). To date, D. tsuruhatensis has not been described as a pathogen. To the best of our knowledge, this is the first report describing D. tsuruhatensis as the(More)
