Impaired HVJ-stimulated Interferon producing capacity in MPO-ANCA-associated vasculitis with rapidly progressive glomerulonephritis lead to susceptibility to infection. Cytokine 2020; 136:155221. [PMID: 32828064 DOI: 10.1016/j.cyto.2020.155221] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 07/20/2020] [Accepted: 07/22/2020] [Indexed: 01/01/2023]
Abstract
ANCA-associated RPGN leads to renal failure through systemic vasculitis and diffuse crescentic glomerulonephritis. MPO-ANCA-RPGN patients are highly susceptible to infections. Our aim in this study was to uncover reasons why these patients were susceptible to infections. We analyzed various aspects of type I interferon system including HVJ-stimulated IFN-α producing capacity and plasmacytoid dendritic cell (pDC) number in whole blood in MPO-ANCA-RPGN patients. Compared with healthy subjects, MPO-ANCA-RPGN patients showed impaired HVJ-stimulated IFN-α producing capacity and lower pDC number with or without glucocorticoid treatment. Immuno-histological staining of MPO-ANCA-RPGN kidney samples revealed a few but apparent pDC in T cell infiltrating regions even in patients with low pDC number in their peripheral blood. Patients' low HVJ-stimulated IFN-α producing capacity and pDC numbers persisted even after patients underwent several years of treatment. Former infection was determined using patients' serum BPI, Lamp-2 and Calprotectin, since they are reflective of a history of infection. These markers were higher in MPO-ANCA-RPGN patients than in healthy subjects. These results indicate that impaired HVJ-stimulated IFN-α production as well as dysfunction of the IFN system might have resulted from a previous bout of infection and can be partially implicated in patients' long-term susceptibility and vulnerability to infection.

RIG-I and TLR4 responses and adverse outcomes in pediatric influenza-related critical illness. J Allergy Clin Immunol 2020; 145:1673-1680.e11. [PMID: 32035159 PMCID: PMC7323584 DOI: 10.1016/j.jaci.2020.01.040] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2019] [Revised: 01/13/2020] [Accepted: 01/15/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Decreased TNF-α production in whole blood after ex vivo LPS stimulation indicates suppression of the Toll-like receptor (TLR)4 pathway. This is associated with increased mortality in pediatric influenza critical illness. Whether antiviral immune signaling pathways are also suppressed in these patients is unclear. OBJECTIVES We sought to evaluate suppression of the TLR4 and the antiviral retinoic acid-inducible gene-I (RIG-I) pathways with clinical outcomes in children with severe influenza infection. METHODS In this 24-center, prospective, observational cohort study of children with confirmed influenza infection, blood was collected within 72 hours of intensive care unit admission. Ex vivo whole blood stimulations were performed with matched controls using the viral ligand polyinosinic-polycytidylic acid-low-molecular-weight/LyoVec and LPS to evaluate IFN-α and TNF-α production capacities (RIG-I and TLR4 pathways, respectively). RESULTS Suppression of either IFN-α or TNF-α production capacity was associated with longer duration of mechanical ventilation and hospitalization, and increased organ dysfunction. Children with suppression of both RIG-I and TLR4 pathways (n = 33 of 103 [32%]) were more likely to have prolonged (≥7 days) multiple-organ dysfunction syndrome (30.3% vs 8.6%; P = .004) or prolonged hypoxemic respiratory failure (39.4% vs 11.4%; P = .001) compared with those with single- or no pathway suppression. CONCLUSIONS Suppression of both RIG-I and TLR4 signaling pathways, essential for respective antiviral and antibacterial responses, is common in previously immunocompetent children with influenza-related critical illness and is associated with bacterial coinfection and adverse outcomes. Prospective testing of both pathways may aid in risk-stratification and in immune monitoring.

Abstract
We analyzed the blood transcriptome of sepsis framed within community-acquired pneumonia (CAP) and characterized its molecular and cellular heterogeneity in terms of functional modules of co-regulated genes with impact for the underlying pathophysiological mechanisms. Our results showed that CAP severity is associated with immune suppression owing to T-cell exhaustion and HLA and chemokine receptor deactivation, endotoxin tolerance, macrophage polarization, and metabolic conversion from oxidative phosphorylation to glycolysis. We also found footprints of host's response to viruses and bacteria, altered levels of mRNA from erythrocytes and platelets indicating coagulopathy that parallel severity of sepsis and survival. Finally, our data demonstrated chromatin re-modeling associated with extensive transcriptional deregulation of chromatin modifying enzymes, which suggests the extensive changes of DNA methylation with potential impact for marker selection and functional characterization. Based on the molecular footprints identified, we propose a novel stratification of CAP cases into six groups differing in the transcriptomic scores of CAP severity, interferon response, and erythrocyte mRNA expression with impact for prognosis. Our analysis increases the resolution of transcriptomic footprints of CAP and reveals opportunities for selecting sets of transcriptomic markers with impact for translation of omics research in terms of patient stratification schemes and sets of signature genes.

The administration of intranasal live attenuated influenza vaccine induces changes in the nasal microbiota and nasal epithelium gene expression profiles. MICROBIOME 2015; 3:74.

Abstract
BACKGROUND Viral infections such as influenza have been shown to predispose hosts to increased colonization of the respiratory tract by pathogenic bacteria and secondary bacterial pneumonia. To examine how viral infections and host antiviral immune responses alter the upper respiratory microbiota, we analyzed nasal bacterial composition by 16S ribosomal RNA (rRNA) gene sequencing in healthy adults at baseline and at 1 to 2 weeks and 4 to 6 weeks following instillation of live attenuated influenza vaccine or intranasal sterile saline. A subset of these samples was submitted for microarray host gene expression profiling. RESULTS We found that live attenuated influenza vaccination led to significant changes in microbial community structure, diversity, and core taxonomic membership as well as increases in the relative abundances of Staphylococcus and Bacteroides genera (both p < 0.05). Hypergeometric testing for the enrichment of gene ontology terms in the vaccinated group reflected a robust up-regulation of type I and type II interferon-stimulated genes in the vaccinated group relative to controls. Translational murine studies showed that poly I:C administration did in fact permit greater nasal Staphylococcus aureus persistence, a response absent in interferon alpha/beta receptor deficient mice. CONCLUSIONS Collectively, our findings demonstrate that although the human nasal bacterial community is heterogeneous and typically individually robust, activation of a type I interferon (IFN)-mediated antiviral response may foster the disproportionate emergence of potentially pathogenic species such as S. aureus.
