Abstract

Background We studied patients from the Protocolized Care in Early Septic Shock (ProCESS) trial to determine the effects of alternative resuscitation strategies on circulating markers of endothelial cell permeability and hemostasis and the association between biomarkers and mortality. Methods This was a prospective study of biomarkers of endothelial cell permeability (vascular endothelial growth factor [VEGF], soluble fms-like tyrosine kinase 1 [sFLT-1], angiopoietin 2 [Ang-2]) and biomarkers of hemostasis (von Willebrand factor [vWF], thrombomodulin [TM], tissue plasminogen activator [tPA] in 605 of the 1,341 ProCESS participants in a derivation cohort and 305 participants in a validation cohort. Analyses assessed (1) the impact of varying resuscitation strategies on biomarker profiles and (2) the association of endothelial biomarkers with 60-day in-hospital mortality. The study was conducted in 31 US EDs in adult patients with septic shock. Patients were randomly assigned to one of three resuscitation strategies. Blood samples were collected at enrollment, at 6 h, and at 24 h. Results There were 116 (19.2%) and 52 (17.0%) deaths in the derivation and validation cohorts, respectively. There was no significant association between treatment strategy and any biomarker levels. Permeability (Ang-2 and sFLT-1) and hemostasis (vWF, TM, tPA) biomarkers were higher and VEGF levels were lower in nonsurvivors (P < .05 for all). At baseline, sFLT-1 had the highest point estimate for mortality discrimination (derivation area under the curve [AUC], 0.74; validation, 0.70), similar to lactate (AUC, 0.74) and Sequential Organ Failure Assessment score (AUC, 0.73). In an analysis including all time points and adjusted for age, presence of cancer, and Charlson comorbidity score, the adjusted AUC for sFLT-1 was 0.80. Conclusions We found no relationship between different resuscitation strategies and biomarker profiles in sepsis, but we did find that elevated levels of endothelial cell biomarkers of permeability and hemostasis were associated with increased mortality.

  • Inflammation increases capillary permeability.

    “Inflammation increases capillary permeability and escape of serum albumin, leading to expansion of interstitial space and increasing the distribution volume of albumin.”

    From Hypoalbuminemia: Pathogenesis and Clinical Significance (2019) · cites this paper as [35]

    The introductory passage (section labelled “CONCLUSIONS:”; page unavailable) identifies inflammation and vascular permeability as features of sepsis and links endothelial markers to permeability. It does not establish that inflammation itself increases capillary permeability, so the causal claim is stronger than the passage supports. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • In infection mild to severe, serum albumin concentration decreases, vascular permeability increases, absolute synthesis increases, half-life decreases, total mass decreases, distribution volume increases, and VEGF increases.

    “Infection mild to severe | ↓ to ↓↓↓ | ↑ to ↑↑↑ | ↑ to ↑↑↑ | ↓ to ↓↓↓ | ↓ to ↓↓↓ | ↑ to ↑↑↑a | ↑35 | Inflammatory course unpredictable due to bacterial interference”

    From Hypoalbuminemia: Pathogenesis and Clinical Significance (2019) · cites this paper as [35]

    The introductory passage (section labeled CONCLUSIONS; page unavailable) links endothelial permeability and VEGF to sepsis, supporting only the claim’s broad vascular component. The paper does not report the claimed changes in albumin concentration, synthesis, half-life, mass, or distribution volume across mild-to-severe infection. Its Discussion reports discordant VEGF findings, and its own study associates lower VEGF with higher mortality, so it does not establish a general VEGF increase. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • VEGF expression and increased vascular permeability occur in infection, trauma, during fetal and postnatal growth, preparing for lactation, cancer, protein-losing enteropathy, and nephrotic syndrome.

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.
