Whole blood gene expression profiles associated with mortality in community-acquired pneumonia

ABSTRACT: We aimed to examine the differences in the gene expression profile in peripheral blood at hospital admission between patients with community-acquired pneumonia (CAP) who died and survived during hospitalization. Whole blood samples for genome expression profile analysis were obtained within 24 hours of hospital admission. Gen set enrichment analysis (GSEA) identified gene sets positively enriched in the patients who survived, mainly related with interferon- alpha response, apoptosis, and sex hormones pathways. Similarly, GSEA identified gene sets positively enrichment for the patients who died (oxidative stress, endoplasmic reticulum stress, oxidative phosphorylation, and angiogenesis pathways).

High expression of oleoyl-ACP-hydrolase predicts mortality in patients hospitalized with avian A(H7N9) influenza

Project description:Although respiratory viral infections cause significant morbidity and mortality, it is still not fully clear why some individuals succumb to severe disease. In patients hospitalized with avian A(H7N9) influenza, we investigated early drivers underpinning hypercytokinemia and fatal disease. Our transcriptomics studies identified differential expression of 10 early host genes, defined by 16 probe sets, between patients who recovered and died. Seven probe sets were specific for the same host gene encoding for a key enzyme mediating free fatty acid production, oleoyl-ACP-hydrolase (OLAH). High olah transcript levels in fatal A(H7N9) patients were detected early after hospital admission and persisted until patients died. Conversely, patients who recovered had minimal olah transcript expression throughout their hospital stays.

Th2/Th1 cytokine imbalance is associated with higher COVID-19 risk mortality

Project description:In this study we profiled 288 new serum proteomics samples measured at admission from patients hospitalized within the Mount Sinai Health System with positive SARS-CoV-2 infection. We first computed Th1 and Th2 pathway enrichment scores by gene set variation analysis and then compared the differences in Th2 and Th1 pathway scores between patients that died compared to those that survived.

Longitudinal transcriptomic analysis reveals persistent enrichment of iron homeostasis and erythrocyte function pathways in severe COVID-19 ARDS

Project description:The acute respiratory distress syndrome (ARDS) is a common complications of severe COVID-19 and contributes to patient morbidity and mortality. ARDS is a heterogeneous syndrome caused by various insults, and results in acute hypoxemic respiratory failure. Patients with ARDS from COVID-19 may represent a subgroup of ARDS patients with distinct molecular profiles that drive disease outcomes. Here, we hypothesized that longitudinal transcriptomic analysis may identify distinct dynamic pathobiological pathways during COVID-19 ARDS. We identified a patient cohort from an existing ICU biorepository and established three groups for comparison: 1) patients with COVID-19 ARDS that survived hospitalization (COVID survivors, n = 4), 2) patients with COVID-19 ARDS that did not survive hospitalization (COVID non-survivors, n = 5), and 3) patients with ARDS from other causes as a control group (ARDS controls, n = 4). RNA was extracted from peripheral blood mononuclear cells (PBMCs) at 4 time points (Days 1, 3, 7, and 10 following ICU admission) and prepared for RNA sequencing with rRNA depletion and library generation for Illumina. An Illumina NovaSeq X Plus instrument was used to generate 150 base pair paired-end reads, which were aligned to the hg GRCh38.96 reference genome using HiSAT2. Differential expression analysis was performed with DESeq2.

Immunomodulatory fecal metabolites are associated with mortality in COVID-19 patients with respiratory failure

Project description:Respiratory failure and mortality from COVID-19 result from virus- and inflammation-induced lung tissue damage. The intestinal microbiome and associated metabolites are implicated in immune responses to respiratory viral infections, however their impact on progression of severe COVID-19 remains unclear. We prospectively enrolled 71 patients with COVID-19 associated critical illness, collected fecal specimens within 3 days of medical intensive care unit admission, defined microbiome compositions by shotgun metagenomic sequencing, and quantified microbiota-derived metabolites (NCT 04552834). Of the 71 patients, 39 survived and 32 died. Mortality was associated with increased representation of Proteobacteria in the fecal microbiota and decreased concentrations of fecal secondary bile acids and desaminotyrosine (DAT). A microbiome metabolic profile (MMP) that accounts for fecal secondary bile acids and desaminotyrosine concentrations was independently associated with progression of respiratory failure leading to mechanical ventilation. Our findings demonstrate that fecal microbiota composition and microbiota-derived metabolite concentrations can predict the trajectory of respiratory function and death in patients with severe SARS-Cov-2 infection and suggest that the gut-lung axis plays an important role in the recovery from COVID-19.

Human patients with influenza virus and bacterial infections

Project description:Peripheral blood was collected from human patients infected with influenza A virus only or in addition with bacterial pathogens and at different days after hospital admission. For comparison, blood from healthy controls was collected. Gene expression differences were detected in influenza and bacterial infections compared to healthy controls, and at various days post infection.
