Objectives: To determine and compare the respective concentrations of tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, soluble TNF receptors, nitrite/nitrate (NO2-/NO3-), and procalcitonin in the plasma of patients with septic shock, cardiogenic shock, and bac terial pneumonia without shock; and to assess the predictive Value of these mediators in defining patients with septic shock.Design: Cohort study, comparing normal volunteers (controls) and patients with septic shock, cardiogenic shock, and bacterial pneumonia.Setting: A collaborative study among an intensive care unit, an emergency room, and three research laboratories.Patients: Mediators were measured at various times in 15 patients with septic shock (during the shock phase and during the recovery phase), in seven patients with cardiogenic shock during the shock phase, and in seven patients with severe bacterial pneu monia on day 1 of admission. interventions: Blood samples were collected at various times during the course of the disease.Measurements and Main Results: TNF-alpha values were highest in the acute phase of septic shock (53 to 131 pg/mL during septic shock), while patients with bacterial pneumonia had intermediate concentrations (32 pg/mL). TNF-alpha concentrations were normal in patients with cardiogenic shock. IL-6 concentrations were highest in patients with acute septic shock (85 to 385 pg/mL). However, in contrast to TNF-alpha concentrations, IL-6 concentrations were normal in patients with bacterial pneumonia and increased in patients with cardiogenic shock (78 pg/mL). Soluble TNF receptors were increased in all three groups vs, controls, with the highest increase in patients with septic shock. NO2-/NO3- concentrations were highest (72 to 140 mM) in patients with septic shock, and were
