[Local activation of blood coagulation in pancreatic tissue in chronic pancreatitis].

Thromboembolic events may complicate clinical course of chronic pancreatitis. It is accepted that trypsin plays a role in the pathogenesis of these abnormalities. However there is a lack of information about local activation of blood coagulation in pancreatic tissue in chronic inflammation and contribution of tissue factor (TF) to this process. Immunohistochemistry was applied to AMeX-fixed sections of tissues of ten cases of chronic pancreatitis to explore the presence and distribution of components of the coagulation system in situ. TF antigen was present in cells of ductules. Fibrinogen and fibrin were detected in the inflammatory infiltrates of the pancreatic tissue. The data suggest that there is local activation of blood coagulation in pancreatic tissue in chronic inflammation that depends on tissue factor.
