Abstract
Study of the behavior of serum amylase activity in 200 preganant women in various stages of pregnancy indicated that: (1) serum amylase rises gradually during pregnancy until the twenty-fifth week and thereafter falls slightly; (2) serum amylase values may be found in normal pregnant women during the second and third trimesters that exceed those in normal men and nonpregnant women; (3) during the second trimester of pregnancy there may be an alteration in the relative distribution of the pancreatic and salivary-type isoamylases with the salivary type tending to dominate. Knowledge of these changes is of importance in the clinical assessment of serum amylase values in pregnant women complaining of abdominal pain and other symptoms suggestive of complicating acute pancreatitis. An explanation for the observed changes is not readily available and further study is required.
