The association of viral hepatitis and acute pancreatitis.
The histological features of 24 pancreases obtained from patients who died of causes other than hepatitis, pancreatitis or pancreatic tumors, included a variable degree of autolysis, rare foci of inflammatory reaction but no hemorrhagic fat necrosis or destruction of elastic tissue in vessel walls (elastolysis). Assays of elastase in extracts of these pancreases showed no free enzyme, but varying amounts of proelastase.A review of autopsy findings in 33 patients with fatal liver necrosis attributed to halothane anesthesia, demonstrated changes of acute pancreatitis only in two. On the other hand, a review of 16 cases of fulminant viral hepatitis revealed changes characteristic of acute pancreatitis in seven - interstitial edema, hemorrhagic fat necrosis, inflammatory reaction and frequently elastolysis in vessel walls. Determination of elastase in extracts of one pancreas showed the bulk of the enzyme in free form. Furthermore, assays of urinary amylase in 44 patients with viral hepatitis showed increased levels of this enzyme (2583 +/- 398 mean value +/- standard error, Somogyi units per 100 ml in 13, or 29.5 percent). The evidence suggests that acute pancreatitis may at times complicate viral hepatitis. Although direct proof of viral pancreatic involvement is not feasible at present, a rational hypothesis is advanced which underlines similar mechanisms of tissue involvement in both liver and pancreas that may be brought about by the hepatitis viruses.
