Metaproteomics on preterm infant stool

ABSTRACT: Development of the gut microbiota is greatly impacted in preterm infants. Despite increasing knowledge about microbiota composition in preterm infants, knowledge about the functional signatures of the intestinal microbiota remains limited. The aim was to study transitions in microbiota activity during the first six postnatal weeks in ten preterm infants. A total of 64 stool samples were measured by LC-MS/MS.

<h4>Objective</h4>Development of the gastrointestinal tract and immune system can be modulated by the gut microbiota. Establishment of the intestinal microbiota, in its turn, is affected by host and environmental factors. As such, development of the gut microbiota is greatly impacted in preterm infants, who have an immature gut and are exposed to factors like hospitalization, caesarean section, antibiotics, and respiratory support.<h4>Design</h4>We analyzed fecal microbiota composition and activ ...[more]

Data in support of Prenatal intra-amniotic lipopolysaccharide induces neonatal renal immune activation after preterm birth

Project description:Preterm birth is often predisposed by chorioamnionitis (CA) and CA affects the fetal gut and lungs via intra-amniotic (IA) inflammation, thus accentuating the proinflammatory effects of preterm birth. It is not known if IA inflammation also affects other perfusion-sensitive organs (e.g., kidneys) before and after preterm birth. Using preterm pigs as model for preterm infants, we hypothesized that CA induces fetal and neonatal renal dysfunctions that can intially be detected via plasma proteome, partly explaining the frequent renal dysfunction in preterm infants. Fetal pigs (88% gestation) were given an IA dose of lipopolysaccharide (LPS, 1 mg/kg, n=28), delivered preterm by cesarean section three days later, and compared with controls (CON, n=26) at birth and postnatal day five. Plasma proteome and protein markers of inflammatory pathways were evaluated.

Microbiota-associated intestinal methylation changes confer immune-metabolic gene network of NEC in preterm pig model

Project description:Intestinal microbiota colonization is important for intestinal development and health of preterm infants, especially those with extremely low birth weight. Recent studies indicated for a dynamic crosstalk between that gut microbiota and DNA methylome of host intestinal cells. Thereby, we sought to determine the epigenomic and metagenomic consequences of suppression of microbiota colonization in the intestine of preterm neonates to gain insights into biological pathways that shape the interface between the gut microbiota and the preterm intestinal cells. We examined 14 preterm piglets by comparing the conventional preterm neonates with those ones treated with oral antibiotics for genome wide DNA methylation and 16S rDNA microbiome. Our results demonstrated an extensive genome-wide DNA methylation changes in response to the suppression of intestinal microbe colonization, especially genes involved in neonatal immune response signaling and glycol-metabolism pathways were identified. Our study highlights several key genes that might predispose preterm neonates to NEC risk due to their key roles involved in the immune-metabolic networks. Our study not only provided rich omic-data to interpret molecular program in relation with microbiota-associated methylome-proteome network changes, but also confer clinical usage of key gene markers for potential early diagnostics of NEC of preterm neonates.

Fecal filtrate transfer protects against necrotizing enterocolitis in preterm pigs

Project description:Necrotizing enterocolitis (NEC) is an acute and life-threatening gastrointestinal disorder afflicting preterm infants, which is currently unpreventable. Fecal microbiota transplantation (FMT) is a promising preventative therapy, but potential bacterial infection raise concern. Removal of bacteria from donor feces may reduce this risk while maintaining the NEC-preventive effects. We aimed to assess preclinical efficacy and safety of bacteria-free fecal filtrate transfer (FFT). Using fecal material from healthy suckling piglets, we administered FMT rectally, or cognate FFT either rectally or oro-gastrically to formula-fed preterm, cesarean-delivered piglets as a model for preterm infants, We compared gut pathology and related safety parameters with saline controls, and analyzed ileal mucosal transcriptome to gauge the host e response to FMT and FFT treatments relative to control. Results showed that oro-gastric FFT prevented NEC, whereas FMT did not perform better than control. Moreover, FFT but not FMT reduced intestinal permeability, whereas FMT animals had reduced body weight increase and intestinal growth. Global gene expression of host mucosa responded to FMT but not FFT with increased and decreased bacterial and viral defense mechanisms, respectively. In conclusion, as preterm infants are extremely vulnerable to enteric bacterial infections, rational NEC-preventive strategies need incontestable safety profiles. Here we show in a clinically relevant animal model that FFT, as opposed to FMT, efficiently prevents NEC without any recognizable side effects. If translatable to preterm infants, this could lead to a change of practice and in turn a reduction in NEC burden.

Whole blood transcriptional responses of very preterm infants during late-onset sepsis

Project description:Host immune responses during late-onset sepsis (LOS) in very preterm infants are poorly characterised due to a complex and dynamic pathophysiology and challenges in working with small available blood volumes. We present here an unbiased transcriptomic analysis of whole peripheral blood from very preterm infants at the time of LOS. RNA-Seq was performed on peripheral blood samples (6 – 29 days postnatal age) taken at the time of suspected LOS from very preterm infants <30 weeks gestational age. Infants were classified based on blood culture positivity and elevated C-reactive protein concentrations as having confirmed LOS (n=5), possible LOS (n=4) or no LOS (n=9). Bioinformatics and statistical analyses performed included pathway over-representation and protein-protein interaction network analyses. Plasma cytokine immunoassays were performed to validate differentially expressed cytokine pathways.The blood leukocyte transcriptional responses of infants with confirmed LOS differed significantly from infants without LOS (1,317 differentially expressed genes). However, infants with possible LOS could not be distinguished from infants with no LOS or confirmed LOS. Transcriptional alterations associated with LOS included genes involved in pathogen recognition (mainly TLR pathways), cytokine signalling (both pro-inflammatory and inhibitory responses), immune and haematological regulation (including cell death pathways), and metabolism (altered cholesterol biosynthesis). At the transcriptional-level cytokine responses during LOS were characterised by over-representation of IFN-α/β, IFN-γ, IL-1 and IL-6 signalling pathways and up-regulation of genes for inflammatory responses. Infants with confirmed LOS had significantly higher levels of IL-1α and IL-6 in their plasma. Blood responses in very preterm infants with LOS are characterised by altered host immune responses that appear to reflect unbalanced immuno-metabolic homeostasis.

Data in support of plasma proteomics study forearly markers of antibiotics dependent necrotising enterocolitis in preterm pigs

Project description:Most hospitalized preterm infants receive antibiotics (AB) in the first days of life to treat or prevent systemic infections. Short-term, early AB treatment may also prevent against the microbiota-dependent serious gut disorder, necrotising enterocolitis (NEC). However, it remains a challenge to predict or early detection of NEC in the first weeks of life and few diagnostic markers exist. Using preterm piglets as models for infants, we hypothesised that proteomic profiling could be used to identify new early plasma biomarkers of NEC with or without prior AB treatment. Preterm newborn pigs were treated with saline (CON) or antibiotics (ampicillin, gentamicin, and metronidazole), given enterally (ENT) or parenterally (PAR), and fed formula for four days to induce NEC. The gut was collected for scoring of NEC lesions and blood was collected for haematology and plasma proteomics

Airway Exosomal miRNA predicts Bronchopulmonary Dysplasis in Extremely Preterm Infants

Project description:We conducted a prospective cohort study with independent Discovery and Validation cohorts, to formulate predictive biomarkers for Bronchopulmonary Dysplasia in extremely preterm infants. Tracheal aspirate samples were collected at birth from extremely preterm infants. Exosomes were extracted from tracheal aspirates and total RNA was extracted from these exosomes from individual samples. miRNA profiling for all ~ 800 miRNAs was conducted on each sample by nanostring platform. This study found that a distinct airway exosomal miRNA sigrature at birth (decreased miR 876-3p) predicts future development of severe Bronchopulmonary Dysplasia in extremely preterm infants.
