Abstract

BACKGROUND: Graft-versus-host disease (GVHD) is common after allogeneic hematopoietic cell transplantation (HCT). Risk for death from GVHD has been associated with low bacterial diversity in the stool microbiota early after transplant; however, the specific species associated with GVHD risk remain poorly defined. METHODS: We prospectively collected serial weekly stool samples from 66 patients who underwent HCT, starting pre-transplantation and continuing weekly until 100 days post-transplant, a total of 694 observations in HCT recipients. We used 16S rRNA gene polymerase chain reaction with degenerate primers, followed by high-throughput sequencing to assess the relative abundance of sequence reads from bacterial taxa in stool samples over time. RESULTS: The gut microbiota was highly dynamic in HCT recipients, with loss and appearance of taxa common on short time scales. As in prior studies, GVHD was associated with lower alpha diversity of the stool microbiota. At neutrophil recovery post-HCT, the presence of oral Actinobacteria and oral Firmicutes in stool was positively correlated with subsequent GVHD; Lachnospiraceae were negatively correlated. A gradient of bacterial species (difference of the sum of the relative abundance of positive correlates minus the sum of the relative abundance of negative correlates) was most predictive (receiver operator characteristic area under the curve of 0.83) of subsequent severe acute GVHD. CONCLUSIONS: The stool microbiota around the time of neutrophil recovery post-HCT is predictive of subsequent development of severe acute GVHD in this study.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • 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”
  • This multicenter study extends earlier findings from smaller single-center cohorts.

    “The results of this international study extend previous observations that have been made in smaller, single-center cohorts.3,4,8,36”

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.
