title: Trauma severity-dependent changes in AT III activity.
abstract: Trauma may cause a relevant reduction in antithrombin (AT) III activity, which is associated with adverse events. The very early changes in AT III activity after accident trauma are still unclear and possible relations with Interleukin (IL)-6, which is known to interact with AT III, have not been investigated so far. Upon approval of the IRB/IEC, 30 patients were enrolled with multiple injuries (ISS 9-75). Groups were performed according to injury severity, IL-6 concentration, and survivors versus non-survivors. Blood samples were collected at the scene of accident then at 2, 4, 6, 12, and 24 h and at day 3, 5, 10 and 15. No patient received AT III concentrates. In all groups a reduction in AT III activity occurred, which was most pronounced in very severe injuries. The activity re-increased spontaneously and steadily in all groups regardless of the IL-6 concentration. There was no clear impact of the AT III activity on survival.
