Proteolytic activity in pancreatic pseudocyst fluid.
Pancreatic pseudocyst fluids from 15 patients were biochemically analyzed, especially concerning proteolytic activity and protease inhibitors, and correlated to the clinical course. The pseudocyst fluid was a mixture of pancreatic juice and plasma possessing a high proteolytic activity against high- as well against low-mol-wt proteins. There was practically no functional protease inhibitory capacity left, although immunoreactive inhibitors were present. No distinct biochemical findings differed between fluids from "acute" or from "chronic" pseudocysts. It is concluded, that high proteolytic activity within a pancreatic pseudocyst could well explain symptoms as well as complications caused by the pseudocyst. Biochemical analysis of the pseudocyst fluid cannot, however, be used to differentiate between pseudocysts with a harmless or a complicated course.
