Serum levels of tumor necrosis factor (TNF) were significantly higher in patients with septic shock compared to those with sepsis alone. Elevated TNF indicates a critical role in human septic shock pathogenesis and patient survival.

Area of Science:

  • Immunology
  • Pathophysiology

Context:

  • Sepsis and septic shock are life-threatening conditions.
  • Tumor necrosis factor (TNF) is implicated in the pathogenesis of septic shock.

Purpose:

  • To confirm the involvement of TNF in human septic shock.
  • To measure serum TNF levels in patients with sepsis and septic shock.

Summary:

  • Serum TNF levels were measured in adult patients in intensive care for sepsis.
  • Significantly higher TNF levels were observed in patients with septic shock (354 pg/ml) versus sepsis without shock (145 pg/ml).
  • Higher TNF levels correlated with non-survival and were negatively correlated with platelet count.

Impact:

  • These findings support a key pathophysiological role for TNF in human sepsis and septic shock.

  • A critical TNF level of 250 pg/ml was identified, differentiating shock and predicting early mortality.
  • Results highlight TNF as a potential biomarker for sepsis severity and prognosis.
