Gene expression signatures identify pediatric patients with multiple organ dysfunction who require advanced life support in the intensive care unit

ABSTRACT: Multiple organ dysfunction syndrome (MODS) can result from a variety of initiating events such as infection or trauma. The clinical condition of some MODS patients may deteriorate and require intense resource and high-risk cardiopulmonary support via extracorporeal membrane oxygenation (ECMO). Until now, no diagnostic criteria/molecular biomarker has been developed to identify MODS patients who require subsequent ECMO support. We used multi-time point (0h, 72h and 8d) whole transcriptomics from total blood of 27 patients (contro-4, MODS-17 and ECMO-6) to derived the molecular signatures to diagnose the MODS patients required ECMO support. We observed that immune response (neutrophil level) was compromised in MODS patients, who required ECMO support. Differential gene expression analysis and gene ontology enrichment has revealed that epigenetic modifications has got activated during the MODS deterioration to ECMO. In addition, signature of 6 genes were identified using logistic regression, which can be used as putative diagnostic markers for patients needed ECMO support.

The characterisation of protein and cellular binding in paediatric extracorporeal membrane oxygenation (ECMO) circuits using proteomics, immunofluorescence, and scanning electron microscopy

Project description:Extracorporeal membrane oxygenation (ECMO) has been increasingly applied to both adult and paediatric patients worldwide. However, continuous contact between blood and foreign surface of the ECMO circuit may contribute to haemostatic, inflammatory and other physiological disturbances during ECMO. Although previous studies have extensively investigated blood samples from patients on ECMO, the protein and cellular binding to the ECMO circuit has largely been overlooked as an additional factor that could contribute to differences in clinical outcomes. The detailed protocol described in this paper enables the comprehensive characterisation of protein and cellular binding in paediatric ECMO circuits, which could extend our knowledge of the pathophysiology of circuit binding and provide guidance for improved ECMO circuit design.

The characterisation of protein binding in paediatric extracorporeal membrane oxygenation (ECMO) circuits

Project description:The present study aims to characterise proteins bound to circuits collected from children on extracorporeal membrane oxygenation (ECMO). ECMO circuits were collected from 6 patients. Quantification of concentrations for proteins bound to the ECMO circuit samples was performed using bicinchoninic acid (BCA) protein assay, whilst characterisation of the bound proteome was performed using Data-independent acquisition Mass Spectrometry (DIA-MS). Reactome Over-representation Pathway Analyses tool was used to identify functional pathways corresponding to the common proteins bound to circuits across all patients.

Molecular Prognosis of Cardiogenic Shock Patients under Extracorporeal Membrane Oxygenation

Project description:Prognosis for cardiogenic shock patients under ECMO was our study goal. Success defined as survived more than 7 days after ECMO installation and failure died or had multiple organ failure in 7 days. Total 34 cases were enrolled, 17 success and 17 failure. Peripheral blood mononuclear cells collected at ECMO installation were used analyzed.

Transcriptional Profiling in Sepsis-induced Experimental Multiple Organ Dysfunction Syndrome

Project description:Sepsis-induced multiple organ dysfunction syndrome (MODS) is a major cause of morbidity and mortality in critically ill patients and remains impervious to most therapeutic interventions. We utilized a clinically relevant murine model of MODS induced by ventilator-associated pneumonia to systematically delineate pathways dysregulated in lung, liver, and kidney. We focused on processes commonly activated across injured organs and constructed a MODS-associated network based on connectivity among the gene members of these functionally coherent pathways. Our analyses led to the identification of several putative drivers of MODS whose expression was regulated by epidermal growth factor receptor. Our unbiased, integrative method is a promising approach to unravel mechanisms in system-wide disorders afflicting multiple compartments such as sepsis-induced MODS, and guide the discovery of novel putative therapeutic targets.

Transciptomic signature of chronic antibody-mediated kidney rejection traited by extracorporeal photopheresis

Project description:Background: The benefit of extracorporeal photopheresis on the course of kidney transplant rejection is unknown. The aim of our study was to investigate the variations in transcriptomics on graft biopsies when extracorporeal photopheresis was used to treat chronic humoral rejection after kidney transplantation. Methods: we retrospectively analyzed the mRNA expression of 770 genes of interest in graft biopsies performed before and after treatment. Eight patients received an average of 23 extracorporeal photopheresis sessions over 4 months between the two biopsies. Results: Transcriptomic analysis of the graft biopsies identified a significant (adjusted p-value< 0.05) increase in CAV1 mRNA in all patients and a significant decrease in CD19, IL21, PAX5, and SFTPA2 mRNAs in 7 of 8 patients. Conclusions: In patients treated with extracorporeal photopheresis for chronic humoral rejection after renal transplantation, omic analysis of repeated biopsies shows a reduction in fibrotic and inflammatory transcriptomic signatures.

Expression profiling of PBMCs from VA-ECLS patients

Project description:We profiled RNA expression by means of single cell RNA-Seq from a total of ~60,000 cells from 38 patients undergoing VA-ECMO due to acute heart failure (including acute exacerbation of chronic failure). Samples were taken at the time of initiation of ECMO (mean +/- 79 minutes from cannulation).
