  • Title: Hyperamylasemia in bulimia nervosa.
    Author: Walsh BT, Wong LM, Pesce MA, Hadigan CM, Bodourian SH.
    Journal: J Clin Psychiatry; 1990 Sep; 51(9):373-7. PubMed ID: 1698766.
    Abstract:
    To determine the value of total serum amylase levels and salivary and pancreatic isoenzyme levels as biologic indices of behavioral disturbance in bulimia nervosa, the authors monitored these levels in 40 bulimic patients participating in a placebo-controlled trial of desipramine and in 25 controls. In the patients, the total and salivary amylase levels were significantly elevated and a significant correlation existed between the frequencies of binge eating and vomiting and the level of salivary amylase. However, the ability to discriminate patients from controls on the basis of serum amylase levels was limited. In addition, a significant positive relationship between binge frequency and level of serum amylase was observed in less than one quarter of 22 patients with five or more amylase determinations. Therefore, although hyperamylasemia is associated with bulimia nervosa, we believe that serum amylase determinations have limited utility in the assessment of patients with this syndrome.
