Fidan S, et al. - Researchers carried out this study to assess thrombin-antithrombin III complex (TAT) and other hemostatic parameters in patients with acute pancreatitis (AP). Moreover, they investigated whether or not these parameters indicated the severity of AP. In this study, the coagulation cascade was activated in the AP patients and this was shown to become more pronounced as the severity of the disease increased. In patients with AP, plasma TAT levels at the time of presentation could be used as a marker for predicting the severity of the disease.
