title: [Fibrosis markers in heavy alcohol drinkers].
abstract: Alcoholic intake has increased in society in recent years. gamma-GTP is used as a marker of liver damage by alcohol intake, but there is no reliable marker of pancreatic fibrosis. We used animal experiments and clinical data to identify a new reliable marker of early-stage pancreatic fibrosis. Pancreatic fibrosis is induced by intra-peritoneal injection of diethyldithiocarbamate. Pancreas tissue was extracted and measured. Human pure pancreatic juice was collected by endoscopic procedures. Prolyl hydroxylase in pancreas tissue is increased in the early stage of pancreatic fibrosis. Secretion of matrix metalloproteinase from pancreatic stellate cells is increased by diethyldithiocarbamate stimulation. Pancreatic stellate cells, prolyl hydroxylase and a tissue inhibitor of metalloproteinase in human pure pancreatic juice is increased in heavy alcohol drinkers and normalized in former alcohol drinkers. Active matrix metalloproteinase 2 is detected in pure pancreatic juice of chronic pancreatitis patients. Treatment with oral camostat increases pancreatic secretory trypsin inhibitor in chronic pancreatitis patients. Experimental and clinical data indicated that matrix metalloproteinase 2 and prolyl hydroxylase are candidates as markers of early-stage pancreatic fibrosis. Clinical data showed that tissue inhibitor of metalloproteinase and pancreatic secretory trypsin inhibitor in pure pancreatic juice had potential as markers of early-stage pancreatic fibrosis.
