Abstract

Next-generation sequencing of the hypervariable V3 region of the 16s rRNA gene isolated from serial stool specimens collected from 31 patients receiving allogeneic stem cell transplantation (SCT) was performed to elucidate variations in the composition of the intestinal microbiome in the course of allogeneic SCT. Metagenomic analysis was complemented by strain-specific enterococcal PCR and indirect assessment of bacterial load by liquid chromatography-tandem mass spectrometry of urinary indoxyl sulfate. At the time of admission, patients showed a predominance of commensal bacteria. After transplantation, a relative shift toward enterococci was observed, which was more pronounced under antibiotic prophylaxis and treatment of neutropenic infections. The shift was particularly prominent in patients that developed subsequently or suffered from active gastrointestinal (GI) graft-versus-host disease (GVHD). The mean proportion of enterococci in post-transplant stool specimens was 21% in patients who did not develop GI GVHD as compared with 46% in those that subsequently developed GI GVHD and 74% at the time of active GVHD. Enterococcal PCR confirmed predominance of Enterococcus faecium or both E. faecium and Enterococcus faecalis in these specimens. As a consequence of the loss of bacterial diversity, mean urinary indoxyl sulfate levels dropped from 42.5 ± 11 μmol/L to 11.8 ± 2.8 μmol/L in all post-transplant samples and to 3.5 ± 3 μmol/L in samples from patients with active GVHD. Our study reveals major microbiome shifts in the course of allogeneic SCT that occur in the period of antibiotic treatment but are more prominent in association with GI GVHD. Our data indicate early microbiome shifts and a loss of diversity of the intestinal microbiome that may affect intestinal inflammation in the setting of allogeneic SCT.

  • Allogeneic HCT patients show microbiota disruption, including overgrowth of potential pathogens and reduced alpha diversity.

    “We and others have reported that patients undergoing allogeneic hematopoietic-cell transplantation have microbiota disruption that is characterized by expansions of potentially pathogenic bacteria and loss of alpha diversity — a variable that reflects the number of unique bacterial taxa present and their relative frequencies.2–5”
  • Single-center studies have linked post-HCT intestinal microbiota features to relapse, GVHD, infection, organ toxicity, and overall survival.

    “Each of these outcomes, as well as overall survival, has been associated in single-center studies with features of the intestinal microbiota in the period after hematopoietic-cell transplantation.2–4,8–15”
  • After allogeneic stem cell transplant, the gut microbiota loses diversity and stability and becomes dominated by Enterococcus, Streptococcus and Proteobacteria.

    “a disruption of the existing state of equilibrium of the gut microbiota post-HSCT with a relative dysbiosis and a loss of bacterial diversity and stability and dominance of Enterococcus, Streptococcus and various Proteobacteria”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
