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)
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)
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)
To assess the clinical and echocardiographic time course, prognosis, and possible etiology of HIV-associated primary pulmonary hypertension (PPH), we prospectively followed all 19 patients in whom PPH was diagnosed in our centers. Women (12 cases) and injecting drug use (16 cases) predominated; the median CD4 lymphocytes count was 83/microliter (range, 1 to(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)
BACKGROUND Uncontrolled studies suggested that aerosolized iloprost, a stable analogue of prostacyclin, causes selective pulmonary vasodilatation and improves hemodynamics and exercise capacity in patients with pulmonary hypertension. METHODS We compared repeated daily inhalations of 2.5 or 5.0 microg of iloprost (six or nine times per day; median inhaled(More)
Induction therapy of promyelocytic leukemia with all-trans retinoic acid is a standard therapy despite significant side-effects. The most important, the "retinoic acid syndrome", consists of a hyperinflammatory reaction with capillary leakage (edema, pleural, and pericardial effusion), infiltration of myeloid cells into internal organs and systemic signs of(More)
The objective of this prospective study was to assess safety and efficacy of exercise training in a large cohort of patients with different forms and World Health Organization (WHO) functional classes of chronic pulmonary hypertension (PH). 183 patients with PH (pulmonary arterial hypertension (PAH), chronic thromboembolic PH and PH due to respiratory or(More)
Cytomegalovirus (CMV) continues to be a cause of substantial morbidity and death after solid-organ transplantation. There are 3 major consequences of CMV infection: CMV disease, including a wide range of clinical illnesses; superinfection with opportunistic pathogens; and injury to the transplanted organ, possibly enhancing chronic rejection.
