Abstract

Objectives Chronic mesenteric ischemia (CMI) is a debilitating condition arising from intestinal malperfusion from mesenteric artery stenosis/occlusion. Mesenteric revascularization is the standard of care but carries substantial morbidity/mortality. The majority of perioperative morbidity is secondary to postoperative multiple organ dysfunction, potentially from ischemia/reperfusion injury. The intestinal microbiome is a dense community of microorganisms in the gastrointestinal tract that help regulate pathways ranging from nutritional metabolism to the immune response. We hypothesized that patients with CMI have microbiome perturbations that contribute to this inflammatory response and potentially normalize in the postoperative period. Methods A prospective study of CMI patients who underwent mesenteric bypass/stenting was conducted between 2019-2020. Stools were collected at 3 timepoints: pre-operative clinic, perioperatively within 14 days, and post-operative clinic >30 days post-revascularization. Stool samples from healthy controls were used for comparison. Microbiome was measured by 16S rRNA sequencing on an Illumina-MiSeq® sequence platform and analyzed using qiime2-dada2 bioinformatics pipeline with SILVA database. β-diversity was analyzed using principal coordinates analysis and permutational analysis of variance. α-diversity (microbial richness and evenness) was compared using non-parametric Mann-Whitney-U test. Microbial taxa unique for CMI patients versus controls were identified using the linear discriminatory analysis effect size (LEfSe) analysis. P <0.05 was considered statistically significant. Results Eight patients underwent mesenteric revascularization (25% male; average age: 71). Nine healthy controls were analyzed (78% male; average age: 55). Bacterial α-diversity (number of OTUs) was dramatically reduced in preoperative group versus controls (p=0.03); however, revascularization partially restored the species richness and evenness in perioperative and postoperative phases. Beta-diversity was only different between perioperative and post-operative groups (p=0.03). Further analyses revealed increased abundance of Bacteroidetes and Clostridia taxa pre-operatively and perioperatively compared to controls, which was reduced during post-operative period. Conclusion Patients with CMI have intestinal dysbiosis that resolves after revascularization. This is characterized by loss of alpha-diversity, which is restored perioperatively and is maintained postoperatively. This microbiome restoration demonstrates the importance of intestinal perfusion to sustain gut homeostasis and suggests that the microbiome modulation could be a possible intervention to ameliorate acute and sub-acute post-operative outcomes in these patients.

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.
