First PAH Patients Treated with TIVUS Catheter System in Initial Clinical Trial

SoniVie recently announced that it has completed the first two procedures in an initial clinical trial evaluating TIVUS system (Therapeutic Intra-Vascular Ultrasound) for the treatment of pulmonary arterial hypertension (PAH). TIVUS is a therapeutic catheter inserted into the pulmonary artery to selectively damage nerves associated with PAH disease activity, without touching vessel walls…

Same Immune Cell Dysfunction, But Not Its Cause, Found in All Types of PAH

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,…

PAH in Lupus Patients Needs Close Monitoring and Earlier Treatment

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.

Key Pulmonary Hypertension Risk Factors Identified in Patients on Peritoneal Dialysis

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 …
