Delta-like ligand 4 inhibitor drug treatment induces pulmonary hypertension in cancer clinical trials

Pulmonary arterial hypertension (PAH) is a life-threatening condition with no cure, making research into its underlying mechanisms critical. The platelet-derived growth factor (PDGF) signaling pathway plays a crucial role in vascular remodeling, a key factor in PAH progression. 

Pulmonary hypertension (PH) is a common complication in interstitial lung disease (ILD), but the additional burden it imposes on patients and healthcare systems is not well characterized. This retrospective analysis of claims data from the US Merative MarketScan database assessed hospitalization rates and costs over 2 years in patients with connective tissue disease-related ILD (CTD-ILD) and non-CTD-ILD with or without PH (between January 2017 and December 2019). Index was the date of first ILD claim; baseline was the 12-month preindex period.

In this PH Community Call we discussed: 

• Risk Assessment Models and Event-Free Survival in Pulmonary Arterial Hypertension
• PINK1/Parkin Deficiency Enhances Vascular Remodeling and Aggravates Hypoxia-induced Pulmonary Hypertension

Several disease related factors of pulmonary hypertension (PH) can negatively impact the nutritional status, leading to an increased risk of malnutrition. However, there are no studies on the best method for nutritional screening in PH patients.
