Summary

The Cellular Injury Score (CIS) effectively predicts mortality risk in patients with multiple organ failure (MOF). Higher CIS values indicate greater cellular injury and a poorer prognosis, making it a valuable clinical tool.

Area of Science:

  • Biomedical Engineering
  • Critical Care Medicine
  • Biochemistry

Background:

  • Cellular Injury Score (CIS) quantifies cellular damage using intracellular metabolism parameters: arterial ketone body ratio, osmolality gap, and blood lactate.
  • CIS serves as a potential indicator for assessing the severity of cellular injury.

Purpose of the Study:

  • To prospectively evaluate the utility of the Cellular Injury Score (CIS) as a severity scoring system for patients diagnosed with multiple organ failure (MOF).

Main Methods:

  • A prospective study involving 157 consecutive patients with MOF (58 survivors, 99 nonsurvivors).
  • Evaluation of CIS as a severity scoring system and its correlation with clinical outcomes.

Main Results:

  • Nonsurvivors exhibited significantly higher CIS values than survivors throughout their clinical course.

  • CIS demonstrated a significant correlation with the number of failing organs and the overall mortality rate.
  • Receiver operating characteristic curve analysis identified an optimal CIS cutoff of 4 for maximal clinical course values, effectively distinguishing outcomes and reflecting injury severity.

    • Conclusions:

    • The Cellular Injury Score (CIS) is a valuable index for predicting mortality risk in MOF patients.
    • CIS shows potential for application as a severity scoring system for individual MOF patients, aiding clinical decision-making.
