Specifically, we assessed the prevalence of PH under the new guidelines and its association with waitlist survival. We conducted a retrospective analysis using the OPTN/SRTR database, including 14,156 IPF candidates listed for lung transplantation.

Kaplan-Meier analysis demonstrated worse waitlist survival for patients with PH under both diagnostic thresholds. However, multivariate analysis revealed that mPAP and PVR thresholds were not independently predictive of mortality. Instead, clinical parameters, including 6MWD, functional status, BMI, FVC, PaCO2, and double lung transplant preference, were significant predictors of waitlist mortality.

Evidence showed that long noncoding RNA (lncRNA)-XIST/microRNA (miRNA)-200c-3p axis regulated apoptosis and inflammation in cigarette smoke extract (CSE)-exposed human bronchial epithelial cells. Wenshen Yiqi granule (WSYQG) is a Traditional Chinese medicine compound prescription and often used for treating COPD. However, the current understanding of the mechanism by which WSYQG improves COPD is still limited, which has somewhat restrained its widespread application. Therefore, this study aims to investigate the effects and biological mechanisms of WSYQG on CSE-exposed type II alveolar epithelial (AEC II) cells with cell transfection and miRNA mimics/inhibitors intervention. Cell counting kit-8, flow cytometry, Transwell, Western blot, real-time quantitative reverse transcription PCR, and fluorescence in situ hybridization assays were used. Results showed that WSYQG intervention increased cell viability and decreased levels of IFN-γ, TNF-α and apoptosis, also preventing cell migration in CSE-exposed ACE II cells. Additionally, expression of epithelial marker (ZO-1), Notch1/4 decreased, and mesenchymal markers (vimentin) and Notch2 expression increased in CSE-exposed ACE II cells, while WSYQG intervention antagonized them and also decreased N-cadherin and increased E-cadherin. Silencing lncRNA-XIST enhanced WSYQG's effects on CSE-exposed ACE II cells, while inhibiting miR-200c-3p reversed silencing lncRNA-XIST's effects. Furthermore, dual-luciferase reporter assay system and RNA immunoprecipitation assay proved that lncRNA-XIST acts as a miR-200c-3p sponge.

Diagnosing ILD-PH is challenging due to the limitations of imaging methods. Right heart catheterization (RHC) is the gold standard for diagnosing PH but is limited to ILD patients considered for lung transplantation. This study assessed the usefulness of RHC in diagnosing ILD-PH in a large cohort of 105 patients followed for at least 72 months, examining hemodynamic parameters for survival analysis. We conducted an ambispective cohort study, diagnosing PH as mean pulmonary artery pressure ≥ 20 mmHg, pulmonary arterial wedge pressure < 15 mmHg, and pulmonary vascular resistance > 2 Wood units by RHC. We registered demographic, biochemical, echocardiographic, respiratory, and hemodynamic parameters for survival analyses. Using RHC, we found a PH prevalence of 84.7% among ILD patients who previously exhibited an intermediate-to-high probability of PH by echocardiography. Thirty-nine ILD-PH patients died, yielding a 5-year survival rate of 35%, whereas ILD patients without PH had a survival rate of 100%. Connective tissue disease-associated ILD and interstitial pneumonia with autoimmune features were the predominant ILD subtypes in ILD-PH patients. The ILD-PH group had worse pulmonary function, lower forced vital capacity, and more severe hypoxemia. Kaplan-Meier analyses showed significantly lower survival rates in ILD-PH patients with a 6-min walking distance < 360 m, tricuspid annular plane systolic excursion/pulmonary artery systolic pressure ratio < 0.35 mm/mmHg, venous oxygen saturation < 65%, and pulmonary artery compliance < 2.2 mm/mmHg.

This study aims to investigate the causal effects of lipid-lowering drugs (specifically, inhibitors of APOB, CETP, HMGCR, NPC1L1, and PCSK9) on pulmonary vascular diseases using a Mendelian randomization (MR) approach. We utilized summary-level statistics from genome-wide association studies (GWAS) to simulate the exposure to low-density lipoprotein cholesterol (LDL-C) and its outcomes on pulmonary arterial hypertension (PAH), pulmonary embolism (PE), and pulmonary heart disease (PHD). Single-nucleotide polymorphisms (SNPs) within or near drug target-associated LDL-C loci were selected as proxies for the lipid-lowering drugs.

The inverse variance weighted (IVW) and MR-Egger methods were employed to estimate MR effects.
