Abstract

The interest in the study of endotoxemia in the clinical area has increased recently as a result of a) improved and simplified endotoxin determination e.g. chromogenic-kinetic microplate methods (also an improved blood sampling tool is available), b) incidence of sepsis has increased due to improvement in early (e.g. posttraumatic) survival, c) interest in and good evidence for gut translocation as a source of endotoxemia, d) agents have developed, which can antagonize endotoxins. There is evidence that patients with positive endotoxin test in the ICU have a higher incidence of organ failure. To study the pathophysiological consequences of endotoxemia and possible ways of intervention animal models are necessary. The choice of the experimental setting depends on the aim of the study e.g. whether prolonged observation is necessary in survival studies or whether hemodynamic variables have to be measured or whether therapeutic agents only crossreact with primates. Since LPS levels are quite low in clinical studies, an important factor for selection of a relevant animal might be LPS sensitivity, or the use of additional sensitization techniques e.g. galactosamine. Another important aspect in this context is whether LPS is given as bolus or infused up to several days. In this review the dose, time, and route of LPS administration is also discussed. For screening purposes rodents are usually used, or sometimes rabbits due to their higher LPS sensitivity. Another very sensitive animal model is the sheep, which can be chronically instrumented and as a specialty allows lung lymph drainage and thus studies of LPS effects on pulmonary permeability. Pigs are used for hemodynamic studies and often in therapeutical studies if species-specificity of the drug tested is not important, in cases where a large animal is necessary. Finally the non-human primates offer a number of advantages due to human-like physiology, due to the cross-reactivity of human assay systems and accordingly also cross-reactivity of human therapeutic agents. While the chimpanzee also shares the LPS sensitivity of humans, baboons are insensitive like rodents. Thus each model serves to provide some useful purpose and the selection must be made to meet the requirements of the specific questions to be asked, with special emphasis of the chosen endotoxin model on relevance for the human sepsis state.

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.
