Hereditas 2024; 161:33. [PMID: 39256826 PMCID: PMC11384695 DOI: 10.1186/s41065-024-00333-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2024] [Accepted: 08/24/2024] [Indexed: 09/12/2024] Open
Abstract
BACKGROUND Acute pulmonary embolism (APE) is a major type of venous thromboembolism (VTE) with a high risk of mortality and disability. There is a lack of biomarkers for APE to indicate deteriorating development and predict adverse outcomes. This study evaluated the significance of miR-150-5p in APE aiming to explore a novel potential biomarker for APE. METHODS The study enrolled APE (n = 137) and deep wein thrombosis (DVT, n = 67) patients and collected plasma samples from all study subjects. The expression of miR-150-5p was analyzed by PCR and its significance in screening APE and pulmonary arterial hypertension (PAH) was assessed by receiver operating curve (ROC) and logistic analyses. The study established oxidized low-density lipoprotein (ox-LDL)-induced human venous endothelial cells (HUVECs). Through cell transfection combined with cell counting kit-8 (CCK8), flow cytometry, and enzyme-linked immunosorbent assay (ELISA), the effect of miR-150-5p on ox-LDL-induced HUVEC injury was evaluated. RESULTS Significant downregulation of miR-150-5p was observed in the plasma of APE patients compared with DVT patients (P < 0.0001). The plasma miR-150-5p levels in APE patients occurred PAH was much lower than in patients without PAH (P < 0.0001). Reducing miR-150-5p distinguished APE patients from DVT patients (AUC = 0.912) and was identified as a risk factor for the occurrence of PAH in APE patients (OR = 0.385, P = 0.010). In HUVECs, oxidized low-density lipoprotein (ox-LDL) caused inhibited cell proliferation, enhanced apoptosis, increased pro-inflammatory cytokines, reactive oxygen species (ROS), malondialdehyde (MDA), and decreased superoxide dismutase (SOD). Overexpressing miR-150-5p could promote proliferation, inhibit apoptosis, and alleviate inflammation and oxidative stress of ox-LDL-treated HUVECs. CONCLUSIONS Downregulated plasma miR-150-5p served as a diagnostic biomarker for APE and predicted the predisposition of PAH in APE patients. Overexpressing miR-150-5p could alleviate ox-LDL-induced endothelial cell injury in HUVECs.

Abstract
Objectives Endothelial injury may promote declining lung function. We aimed to investigate in well-treated persons living with HIV (PLWH) whether elevated levels of thrombomodulin (TM) and syndecan-1 (SDC1) are associated with excess lung function decline and worsening dyspnea. Methods A prospective cohort study comprising patients from the Copenhagen municipality. We included 698 PLWH with undetectable viral load. Biomarkers and demographics were measured at baseline, spirometry [forced expiratory volume in one second (FEV1) and forced vital capacity (FVC)] and dyspnea score both at baseline and 2-year follow-up.Both biomarkers were dichotomized at the 3rd quartile. Decline in lung function was estimated using a linear mixed model with patient-specific random effect. Increase in dyspnea score was estimated using a general mixed logistic regression model. Results We did not find an association between elevated SDC1 or TM and an excess decline in neither FEV1: SDC1: 4.5 mL/year (95% CI: -3.9-12.9, p = 0.30), TM: 2.2 mL/year (95% CI: -6.0-10.4, p = 0.60) nor FVC: SDC1: 4.1 mL/year (95% CI: -6.0-14.2, p = 0.42), TM: 1.4 mL/year (95% CI: -8.3-11.1, p = 0.78). A subgroup analysis of never-smokers was consistent with the main analysis.Likewise, we did not find any association between elevated SDC1 and TM and increase in dyspnea score: SDC1: OR 1.43 (95% CI: 0.89-2.30, p = 0.14), TM: OR 1.05 (95% CI: 0.65-1.71, p = 0.26). Conclusion We did not find a significant association between elevated biomarkers of endothelial injury and decline in lung function nor dyspnea.

Assessing coagulopathy and endothelial dysfunction in pediatric venous malformation: A thromboelastometry and syndecan-1 study. Pediatr Blood Cancer 2024; 71:e30915. [PMID: 38369689 DOI: 10.1002/pbc.30915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 01/15/2024] [Accepted: 01/28/2024] [Indexed: 02/20/2024]
Abstract
OBJECTIVE The occurrence of unpredictable pain crises are the principal determinant of the quality of life for patients with venous malformations (VM). A definite coagulation phenomenon, characterized by an increase in D-dimer levels and the presence of phleboliths within the malformation, has been previously reported. By applying Virchow's triad and evaluating intralesional samples, our objective is to delineate the coagulation profile and the extent of endothelial dysfunction within the malformation. METHODS With the authorization of the Ethics Committee, a research project was undertaken on intralesional and extralesional blood samples from 30 pediatric patients afflicted with spongiform VM. Thromboelastometry analyses were performed using ROTEM Sigma, and the concentration of syndecan-1 was determined by ELISA. RESULTS In the ROTEM analyses, the A5, A10, and maximum clot firmness (MCF) values were below the established reference ranges in the intralesional samples in both the EXTEM and INTEM assays, indicating that intralesional clots had significant instability. Furthermore, during the investigation of the delayed fibrinolysis phase using recombinant tissue plasminogen activator (rtPA) in EXTEM analysis, widespread hyperfibrinolysis was observed intralesional. Additionally, analysis of syndecan-1 showed significant differences between extralesional and intralesional levels (p < .026) and controls (p < .03), suggesting differences in the state of endothelium. CONCLUSIONS For the first time, we developed a comprehensive understanding of the coagulopathic profile of VM and the role of endothelial dysfunction in its pathogenesis. These findings will enable the implementation of targeted therapies based on the individual coagulation profiles.

Abstract
Endogenous glycosaminoglycans (GAGs) with a similar structure to heparin are widely distributed in various tissues. A fluorescence probe, namely Heparin Red, can detect polyanionic GAGs in plasma samples. The purpose of this study is to measure endogenous GAGs in various plasma samples obtained from different pathologic states in comparison to healthy controls utilizing this method. Plasma samples were obtained from patient groups including atrial fibrillation (AF), end-stage-renal-disease (ESRD), diabetes mellitus (DM), sepsis, cancer, liver disease (LD), and pulmonary embolism (PE). Normal human plasma (NHP) was used as healthy controls. The Heparin Red kit from Red Probes (Münster, Germany) was used for the quantification of endogenous GAGs in each sample before and after heparinase I degradation. All results were compiled as group means ± SD for comparison. NHP was found to have relatively low levels of endogenous GAGs with a mean concentration of 0.06 μg/mL. The AF, ESRD, DM, and sepsis patient samples had a mean endogenous GAG concentration of 0.55, 0.72, 0.92, and 0.94 μg/mL, respectively. The levels of endogenous GAGs were highest in cancer, LD, and PE patient plasma samples with a mean concentration of 1.95, 2.78, and 2.83 μg/mL, respectively. Heparinase I degradation resulted in a decline in GAG levels in plasma samples. These results clearly show that detectable Heparin Red sensitive endogenous GAGs are present in circulating plasma at varying levels in various patient groups. Additional studies are necessary to understand this complex pathophysiology.

Abstract
Introduction Previous studies have shown that inflammation may contribute to the interplay of endogenous glycosaminoglycans (GAGs) and anti-PF4 antibodies. In this study, we quantified the levels of anti-PF4 antibody isotypes and endogenous GAGs together with inflammatory biomarkers in pulmonary embolism (PE) patients to determine whether there is a relationship in between. Identification of this relationship may provide insight to the complex pathophysiology of PE and HIT and may also be useful for development of potential prognostic, diagnostic and therapeutic interventions. Materials and Methods Plasma samples from PE patients (n: 210) were analyzed for anti-PF4 antibody isotypes and various thrombo-inflammatory cytokines utilizing commercially available biochip array and ELISA methods. The endogenous GAG levels in PE patients’ plasma were quantified using a fluorescence quenching method. The collected data analyzed to demonstrate the relationship between various parameters. Results The endogenous GAG levels were increased in the PE group (P < .05). The levels of anti-PF4 antibody isotypes were higher in varying levels in comparison to the normal group (P < .05). Inflammatory cytokines have shown varying levels of increase with IL-6, IL-8 and IL-10 showing the most pronounced values. Mortality outcome was related to increased GAGs and some of the cytokines. Conclusion In this study, we demonstrated increased levels of anti-PF4 antibody isotypes, endogenous GAGs, and inflammatory biomarkers in a large patient cohort in PE. The levels of the endogenous GAGs and inflammatory biomarkers were associated with PE severity and mortality. More studies are needed to understand this complex pathophysiology.

Abstract
The purpose of this study is to establish a novel pulmonary embolism (PE) risk
prediction model based on machine learning (ML) methods and to evaluate the
predictive performance of the model and the contribution of variables to the
predictive performance. We conducted a retrospective study at the Shanghai Tenth
People's Hospital and collected the clinical data of in-patients that received
pulmonary computed tomography imaging between January 1, 2014 and December 31,
2018. We trained several ML models, including logistic regression (LR), support
vector machine (SVM), random forest (RF), and gradient boosting decision tree
(GBDT), compared the models with representative baseline algorithms, and
investigated their predictability and feature interpretation. A total of 3619
patients were included in the study. We discovered that the GBDT model
demonstrated the best prediction with an area under the curve value of 0.799,
whereas those of the RF, LR, and SVM models were 0.791, 0.716, and 0.743,
respectively. The sensibilities of the GBDT, LR, RF, and SVM models were 63.9%,
68.1%, 71.5%, and 75%, respectively; the specificities were 81.1%, 66.1, 72.7%,
and 65.1%, respectively; and the accuracies were 77.8%, 66.5%, 72.5%, and 67%,
respectively. We discovered that the maximum D-dimer level contributed the most
to the outcome prediction, followed by the extreme growth rate of the plasma
fibrinogen level, in-hospital duration, and extreme growth rate of the D-dimer
level. The study demonstrates the superiority of the GBDT model in predicting
the risk of PE in hospitalized patients. However, in order to be applied in
clinical practice and provide support for clinical decision-making, the
predictive performance of the model needs to be prospectively verified.

Abstract
BACKGROUND The number of studies measuring breakdown products of the glycocalyx in plasma has increased rapidly during the past decade. The purpose of the present systematic review was to assess the current knowledge concerning the association between plasma concentrations of glycocalyx components and structural assessment of the endothelium. METHODS We performed a literature review of Pubmed to determine which glycocalyx components change in a wide variety of human diseases and conditions. We also searched for evidence of a relationship between plasma concentrations and the thickness of the endothelial glycocalyx layer as obtained by imaging methods. RESULTS Out of 3,454 publications, we identified 228 that met our inclusion criteria. The vast majority demonstrate an increase in plasma glycocalyx products. Sepsis and trauma are most frequently studied, and comprise approximately 40 publications. They usually report 3-4-foldt increased levels of glycocalyx degradation products, most commonly of syndecan-1. Surgery shows a variable picture. Cardiac surgery and transplantations are most likely to involve elevations of glycocalyx degradation products. Structural assessment using imaging methods show thinning of the endothelial glycocalyx layer in cardiovascular conditions and during major surgery, but thinning does not always correlate with the plasma concentrations of glycocalyx products. The few structural assessments performed do not currently support that capillary permeability is increased when the plasma levels of glycocalyx fragments in plasma are increased. CONCLUSIONS Shedding of glycocalyx components is a ubiquitous process that occurs during both acute and chronic inflammation with no sensitivity or specificity for a specific disease or condition.

Abstract
The pulmonary vascular endothelium is involved in the pathogenesis of acute and chronic lung diseases. Endothelial cell (EC)-derived products such as extracellular vesicles (EVs) serve as EC messengers that mediate inflammatory as well as cytoprotective effects. EC-EVs are a broad term, which encompasses exosomes and microvesicles of endothelial origin. EVs are comprised of lipids, nucleic acids, and proteins that reflect not only the cellular origin but also the stimulus that triggered their biogenesis and secretion. This chapter presents an overview of the biology of EC-EVs and summarizes key findings regarding their characteristics, components, and functions. The role of EC-EVs is specifically delineated in pulmonary diseases characterized by endothelial dysfunction, including pulmonary hypertension, acute respiratory distress syndrome and associated conditions, chronic obstructive pulmonary disease, and obstructive sleep apnea.

Abstract
Syndecans are important mediators of signalling by transmitting external stimuli into the cells. This role in signal transduction has been attributed mainly to the membrane-bound syndecans. In the last years, however, the soluble ectodomain of syndecans generated by shedding has come into the focus of research as this process has been show to modulate the syndecan-dependent signalling pathways, as well as other pathways. This review summarizes the current knowledge about the induction of syndecan shedding and the different pathways modulated by shed syndecan proteins. This review summarizes the known and putative sheddases for each syndecan and describes the exemplary conditions of sheddase activity for some syndecans. This review summarizes the proposed use of shed syndecans as biomarkers for various diseases, as the shedding process of syndecans depends crucially on tissue- and disease-specific activation of the sheddases. Furthermore, the potential use of soluble syndecans as a therapeutic option is discussed, on the basis of the current literature.

Variants in chondroitin sulfate metabolism genes in thrombotic storm. Thromb Res 2017; 161:43-51. [PMID: 29178990 DOI: 10.1016/j.thromres.2017.11.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Revised: 10/24/2017] [Accepted: 11/19/2017] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Thrombotic storm (TS) presents as a severe, acute thrombotic phenotype, characterized by multiple clotting events and frequently affecting younger adults. Understanding the extensive hypercoagulation of an extreme phenotype as TS will also provide insight into the pathogenesis of a wider spectrum of thrombotic disorders. MATERIAL AND METHODS We completed whole exome sequencing on 26 TS patients, including 1 multiplex family, 13 trios and 12 isolated TS patients. We examined both dominant and recessive inheritance models for known thrombotic factors as well as performed a genome-wide screen. Identified genes of interest in the family and trios were screened in the remaining TS patients. Variants were filtered on frequency (<5% in 1000 genomes), conservation and function in gene and were annotated for effect on protein and overall functionality. RESULTS We observed an accumulation of variants in genes linked to chondroitin sulfate (CS), but not heparan sulfate metabolism. Sixteen conserved, rare missense and nonsense variants in genes involved in CS metabolism (CHPF, CHPF2, CHST3, CHST12, CHST15, SLC26A2, PAPSS2, STAB2) were identified in over one-third of the TS patients. In contrast, we identified only seven variants in known thrombosis genes (including FV Leiden). CONCLUSIONS As CS has multiple functions in the glycocalyx protecting the endothelial cells, reduced availability of CS could diminish the normal control mechanisms for blood coagulation, making these CS metabolism genes strong potential risk factors for TS. Overall, no single gene was identified with strong evidence for TS causality; however, our data suggest TS is mediated by an accumulation of rare pro-thrombotic risk factors.
