People with interstitial lung disease face higher healthcare resource utilization (HCRU) and increased medical costs if they are also diagnosed with pulmonary hypertension (PH-ILD), according to a U.S. study. Factors associated with increased burden and costs include a significantly higher need for inpatient care, longer hospitalizations,  as well as…

Children of cigarette-smoking parents are at greater risk of developing pulmonary arterial hypertension (PHA) within a year after birth, according to a new study by researchers in Iran. Specifically, almost half of babies exposed to parental cigarette smoke were diagnosed with PAH, while none of the children with nonsmoking…

Two molecules, 5-hydroxyindoleacetic acid (5-HIAA) and insulin-like growth factor 1 (IGF-1), showed a potential to diagnose pulmonary hypertension  early in children with congenital heart disease based on their levels in blood and urine samples examined in a study. 5-HIAA is the main product of the breakdown of serotonin, a…

Healthcare costs were found to be more than eight times higher for people with pulmonary arterial hypertension (PAH) compared with patients without the disease in a real-world study — which contributed to the greater economic burden seen for those being treated for PAH. These costs were mainly driven by…

Gemcitabine, a chemotherapy given to treat solid cancers, may drive the onset of pulmonary arterial hypertension (PAH) in patients or worsen existing PAH, a recent study reports. Stopping treatment with gemcitabine, with or without a subsequent PAH-approved treatment, led to clinical improvement or disease stabilization for a majority…

Treatment with Revatio (sildenafil) at a higher dose than the recommended and previously approved doses did not significantly increase mortality of adults with pulmonary arterial hypertension (PAH). That’s according to results from the Phase 3b/4 AFFILIATE trial (NCT02060487), which compared three treatment doses, each given three times…

Levels of fractional exhaled nitric oxide (FeNO) — a measure of how much nitric oxide a person exhales — may be used as a diagnostic tool for severe disease in people with idiopathic pulmonary arterial hypertension (iPAH), a study has found. Specifically, patients with FeNO levels lower than 23…

Findings of a new study into pericytes — cells with multiple functions including immune cell regulation — suggest that targeting a protein known as HIF-2alpha, which is involved in the response to low oxygen conditions, or hypoxia, may be a potential therapeutic approach for pulmonary arterial hypertension (PAH). The…

The U.S. Food and Drug Administration (FDA) has supported Inhibikase Therapeutics’ Phase 2/3 trial of its experimental formulation of imatinib, called IkT-001Pro, for pulmonary arterial hypertension (PAH), the company reports. In a meeting, the FDA asked the company to complete a preclinical study in cells to compare…

Chiesi Group has reached an agreement with Gossamer Bio to develop and market seralutinib for certain types of pulmonary hypertension (PH). The agreement seeks to support the therapy’s ongoing testing in pulmonary arterial hypertension (PAH) and to accelerate its development for pulmonary hypertension associated with…

A diet poor in two amino acids called glutamine and serine may improve the health of pulmonary blood vessels and reduce the progression of pulmonary hypertension (PH), according to a recent study. Specifically, researchers found that these amino acids are used by cells in blood vessels to produce other…

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…
