Comparative StudyActivity of GH/IGF-I axis in trauma and septic patients during artificial nutrition: different behavior patterns?
The aim of this study was to compare several parameters of GH/IGF-I axis activity in septic and trauma patients during Intensive Care Unit (ICU) stay. To this goal, 13 patients with sepsis (SEP) and 16 with trauma (TRA) were studied. Thirty-three adult subjects (AS) were studied as controls. ⋯ The GH response to GHRH in SEP and TRA was similar and lower (p<0.01) than in AS. These findings indicate that IGF-I activity is impaired more in septic than in trauma patients. Reduced IGF-I activity probably reflects peripheral GH resistance though basal and GHRH-induced GH levels were not increased in these conditions.
