[Study on high mobility group-1 protein in patients with multiple trauma].

OBJECTIVE

To study the change in serum high mobility group-1 (HMG-1) protein in patients with multiple trauma and determine its relationship to severity of trauma and multiple organ dysfunction syndrome (MODS).

METHODS

In 33 cases, HMG-1 levels were determined on 1, 3, 7 days after trauma respectively. The values of injury severity score (ISS), acute physiology and chronic health evaluation II (APACHE II) and systemic inflammatory response syndrome (SIRS) score were determined. Meanwhile, the occurrence of organ dysfunction was noted.

RESULTS

The level of serum HMG-1 in patients with multiple trauma was much higher than that of normal controls, and also in those with organ dysfunction. HMG-1 and APACHE II were positively correlated (r=0.495, P=0.016). The level of serum HMG-1 and APACHE II value were much higher in patients with organ dysfunction than those of normal organ function, but there was no significant difference in SIRS score between the two groups (P=0.105).

CONCLUSION

Serum HMG-1 increases in patients with trauma and is positively correlated with severity of trauma. Serial determination of HMG-1 is helpful to discover clinical infection earlier. HMG-1 can be used as a warning indicator of the onset of MODS.
