PM20D1 levels may predict mortality risk in idiopathic PAH

Low levels of PM20D1, a molecule involved in metabolizing lipids, were identified as a risk factor for mortality in people with pulmonary arterial hypertension (PAH), a study reports. As a result, PM20D1, or peptidase M20 domain containing 1, may be a biomarker of disease prognosis, according to scientists. Lipid…

Two genes identified as potential drivers of PAH with HIV infection

Two genes were identified as potential drivers of pulmonary arterial hypertension (PAH) in people with HIV-1 infection in a bioinformatics study, offering new perspectives to uncover the underlying molecular mechanisms that link HIV infection and PAH. The genes ISG15 and IFI27 are established hub genes involved in the type…

Aiming to educate on all things PH for global Awareness Day May 5

More than 80 organizations globally, including the U.S.-based Pulmonary Hypertension Association (PHA), will unite on May 5 for World Pulmonary Hypertension Day, celebrated annually to heighten awareness of pulmonary hypertension (PH), which affects an estimated 75 million people worldwide. This year’s global initiative is led by PHA Europe,…

MACC1 seen as biomarker for PAH in bioinformatics study

MACC1, a gene that’s been linked to overgrowth of cancer cells, is more active in the lungs of people with pulmonary arterial hypertension (PAH) than in healthy individuals, a study out of China found, suggesting it could be used as a diagnostic biomarker for the disease. Researchers also observed…

Low circALMS1 levels could be prognostic biomarker in PH: Study

Low levels of circular RNA Alstrom syndrome protein 1, or circALMS1, may be associated with poor outcomes with pulmonary hypertension (PH), a study suggests. This may be because low circALMS1 levels promote higher numbers and the migration of pulmonary microvascular endothelial cells (PMECs), and reduce the cells’ death. PMECs…

Opsumit shows real-world safety, efficacy for CTD-PAH patients

Most people with pulmonary arterial hypertension (PAH) due to connective tissue disease (CTD) who are using Opsumit (macitenan) do so as part of a combination therapy, according to real-world evidence from two U.S. drug registry studies. Its safety and effectiveness, in terms of clinical outcomes, for these patients…

PH raises risk of severe cardiac, respiratory issues in HIV patients

Having pulmonary hypertension (PH) worsens the likelihood of potentially life-threatening cardiac and respiratory complications in people with human immunodeficiency virus (HIV) infection, a U.S. database study reported. Its findings “can inform clinical practice and help healthcare providers make more informed decisions regarding the screening, diagnosis, and management of PH…
