Stress hyperglycemia in non-diabetic patients independently increases critical illness mortality. Intensive insulin therapy improves outcomes by reducing hyperglycemia and modulating inflammation, suggesting targeted management is crucial.

Area of Science:

  • Critical care medicine
  • Endocrinology
  • Immunology

Context:

  • Stress hyperglycemia, common in non-diabetic patients during acute illness, is an independent predictor of mortality.
  • This elevated blood glucose level impairs immune function and exacerbates inflammatory responses.

Purpose:

  • To review the impact of stress hyperglycemia on immune response and patient outcomes.
  • To highlight the benefits of intensive insulin therapy in managing hyperglycemia during critical illness.

Summary:

  • Stress hyperglycemia negatively affects immune cells and increases inflammation (cytokines, NF-kB, CRP), contributing to worse outcomes.
  • Intensive insulin therapy to normalize glycemia significantly reduces mortality and morbidity in critical illnesses like cardiac and infectious diseases.

  • Insulin's benefits likely stem from mitigating hyperglycemia's detrimental effects and directly modulating the inflammatory cascade.

    • Impact:

    • Normalizing blood glucose with insulin therapy improves survival and reduces complications in critically ill patients.
    • Findings support the investigation of specific hyperglycemia management protocols beyond intensive care units.
    • Understanding insulin's anti-inflammatory role opens avenues for novel therapeutic strategies in critical care.
