The Microbiology of Multiple Organ Failure: The Proximal Gastrointestinal Tract as an Occult Reservoir of Pathogens

Marshall, John C.·1988·Archives of Surgery

Abstract

The microbiology of infection acquired in the intensive care unit (ICU) was studied prospectively in 205 consecutive patients admitted to a surgical intensive care unit. A multiple organ failure (MOF) score was calculated for each admission. Susceptibility to ICU-acquired infection increased with increasing MOF scores. While Escherichia coli, Bacteroides fragilis, and enterococci were the most common isolates from infections present at the time of ICU admission, Staphylococcus epidermidis, Candida, and Pseudomonas dominated infections occurring in patients with high MOF scores. Mortality correlated highly with infection due to S epidermidis or Candida and only poorly with infection due to Pseudomonas or E coli; significant foci of invasive infection were frequently absent at autopsy. Quantitative cultures of proximal gastrointestinal fluid in 16 of these patients showed Candida, S epidermidis, and Pseudomonas to be the most common isolates, and all but one patient colonized with these organisms had invasive infection with the same organism. The proximal gastrointestinal tract appears to be an important occult reservoir of the predominant pathogens in MOF.

  • In critical illness, the stomach and proximal small intestine become overgrown by a small number of species, such as E coli, P aeruginosa, and Enterococcus spp.

  • The upper gastrointestinal tract becomes a stagnant reservoir of potential pathogens whose presence is predictive of extra-abdominal infections and multiorgan failure.

  • The dynamics of the aerodigestive tract become inverted during critical illness: the overgrown microbial reservoir of the stomach and small intestine becomes the primary source community for the mouth and lungs.

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.
