Low serum amylase levels in drinking alcoholics

Area of Science:

• Biochemistry
• Gastroenterology
• Addiction Medicine

Background:

• Serum amylase levels in alcoholics have been observed to increase temporarily after abstinence.
• The precise mechanism behind this transient rise in serum amylase remains unclear.

Purpose of the Study:

• To investigate the underlying mechanisms of temporary serum amylase elevation in alcoholics post-abstinence.
• To differentiate the contributions of pancreatic isoamylase and salivary isoamylase to serum amylase levels.

Main Methods:

• Measurement of total serum amylase, pancreatic isoamylase, and salivary isoamylase in 38 male alcoholic patients.
• Analysis of urinary amylase excretion in relation to serum amylase levels before and after abstinence.

Main Results:

• Serum amylase levels varied post-abstinence, decreasing in some and increasing in others, with contributions from both isoamylase types.
• A notable decrease in the ratio of urine amylase to total serum amylase was observed after abstinence.
• Abstinence appeared to reverse a potential decrease in pancreatic and salivary isoamylase production/secretion during alcohol consumption.

Conclusions:

• The temporary increase in serum amylase post-abstinence in alcoholics is linked to improved isoamylase secretion and reduced urinary excretion.
• Total serum amylase measurement is unreliable for diagnosing pancreatitis in heavy alcohol consumers.
• Understanding these amylase dynamics is crucial for managing alcoholic patients.
