Serum pancreatic enzyme alterations in acute viral hepatitis.
In a group of 167 patients with acute viral hepatitis (AVH), 11 with type A hepatitis, 125 with type B and 31 type non A, non B, the following enzymes were studied: serum amylase (S-AMY) and its isoenzymes (pancreatic and salivary type), urinary amylase (U-AMY), serum lipase (S-TGL) and serum immunoreactive trypsin (i-TRY). In all groups of patients, in the acute phase of illness, a significant increase in S-AMY was observed, in particular in hepatitis type B and non A, non B (p less than 0.001). An increase in U-AMY excretion was recorded in patients with type A hepatitis. S-TGL levels were significantly higher in all groups, especially in patients with type A hepatitis. i-TRY was only slightly higher in patients with hepatitis A and non A, non B. S-AMY isoenzymes showed a peculiar pattern: the pancreatic type (2) of isoamylase was found to be prevalent in 66% of patients with AVH while in controls the salivary type (1) was prevalent in most cases. Pancreatic enzyme alterations correlated neither with laboratory hepatic function tests nor with the clinical syndrome. These results suggest that a pancreatic injury is not uncommon in AVH, although it is seldom severe.
