AMYLASE ISOZYME OF PATIENTS WITH NON-PANCREATIC HYPERAMYLASEMIA

We investigated amylase isozyme of patients with non-pancreatic hyperamylasemia. Ten patients with hyperamylasemia excluding pancreatic, renal or liver disease were chosen. One patient wsa a macroamylasemia (IgA-λtype) with a specific pattern of amylase isozyme. Isozyme patterns of other 9 patients...

Summary:We investigated amylase isozyme of patients with non-pancreatic hyperamylasemia. Ten patients with hyperamylasemia excluding pancreatic, renal or liver disease were chosen. One patient wsa a macroamylasemia (IgA-λtype) with a specific pattern of amylase isozyme. Isozyme patterns of other 9 patients with salivary-type hyperamylase-mia showed P/S ratio between 0.20, -0.59 (mean value was 0.4). The values of S2 fraction were high between 10-2296 (mean value was 13.296). And also, 6 of 9 hade S3 fraction. Seven of those patients had some diseases and were taking medicines, but other 2 patients did not have any diseases or were not taking medicines. The investigation of amylase isozyme is very useful for the differential diagnosis of hyperamylasemia. And, some patients have salivary-type hyperamylasemia with unknown causes.
