Researchers found that key immune cells, called regulatory T lymphocytes (Treg), are dysfunctional in all forms of pulmonary arterial hypertension (PAH), but the nature of the alterations differ among subtypes of the disease. Specifically, Treg dysfunction is leptin-dependent in idiopathic PAH (iPAH) and connective tissue disease-associated PAH, and leptin-independent in heritable PAH. Their study,…
Patients with systemic lupus erythematosus who develop pulmonary arterial hypertension (PAH) have a poorer prognosis, according to a review from the Peking Union Medical College & Chinese Academy of Medical Science, which strongly recommended clinicians pay attention to the simultaneous presence of these conditions, as early diagnosis and management might improve survival.
Drugs chronically blocking the vasopressin type 2 receptor (V2R), such as tolvaptan, may harm people with pulmonary arterial hypertension (PAH) by contributing to the remodeling of lung blood vessels, according to a new study. The study, “Detrimental Impact of Vasopressin V2 Receptor Antagonism in a SU5416/Hypoxia/Normoxia-Exposed Rat Model of…
German researchers evaluating a possible new biomarker for pulmonary arterial hypertension (PAH) found that the molecule, known as chemokine CXC ligand 13 (CXCL13), was higher in the blood serum and lung tissue of people with PAH — suggesting a pathogenic role but one short of serving as a disease marker. The report,…
Recent advances made, and insights gained, in clinical and preclinical research into pulmonary hypertension were highlighted in a Clinical Year in Review article published in the journal European Respiratory Review. The article, “Pulmonary hypertension,” offers hope that pulmonary hypertension might become a well-managed, and potentially even…
In this video from CHEOvideos, watch Dr. Kyle Cowan, pediatric surgeon and scientist at CHEO, talk about his research on diaphragmatic hernias in infants. “These types of hernias can lead to poor lung development, pulmonary hypertension and even death. Dr. Cowan and his team have…
A systematic review of clinical trial data showed that exercise training improves exercise capacity and the quality of life in patients with pulmonary arterial hypertension (PAH). The study concluded that exercise training should, like medications, be a recommended treatment for PAH. The study, “Effects of Exercise…
Chinese researchers identified a number of risk factors for the development of pulmonary hypertension (PH) in patients under maintenance peritoneal dialysis — and demonstrated that the highest risks were associated with the proportion of arteriovenous fistula, C-reactive protein levels (a measure of inflammation), and ejection fraction measured in the dialysis patients. Researchers with …

The award, given to businesses for pioneering work in drug discovery and development, also acknowledged Actelion’s work with pulmonary…
Team Phenomenal Hope, a nonprofit group composed of medical and athletic professionals that uses endurance sporting events to spread awareness about pulmonary hypertension (PH), has just returned from a seven-day trek along the Southern Alps, and is now planning its next lap in the journey against the disease. The team…
