Liver damage in a woman who had taken an overdose of paracetamol and dextropropoxyphene was assessed by monitoring serum prealbumin concentrations and by routine plasma enzyme determinations. The plasma aspartate aminotransferase returned to normal levels after 3 days, alkaline phosphatase was slow to show increases in activity, and serum albumin concentration was in the normal range throughout. Prothrombin-time, although initially very high, returned almost to normal as a result of the administration of plasma. In contrast, serum prealbumin concentration decreased significantly after 36 h and continued to decrease, showing the course of failing liver function, until the patient's death 15 days after presentation. Prealbumin, a functional plasma protein synthesised in the liver, has a short half-life, is a true index of liver function, and seems to be a more reliable indicator of liver function in drug overdose than plasma enzymes, prothrombin-time, or plasma drug concentration.

Of 33 components analyzed in overnight fasting serum from 30 patients with alcoholic liver cirrhosis, portal hypertension, and bleeding esophageal varices, total serum bile acids, gamma-glutamyltransferase, prealbumin, and tyrosine were the most frequently abnormal 'liver tests'. Total serum bile acids correlated significantly with bilirubin, immunoglobulin M, threonine, glycine, methionine, and tyrosine. Gamma-glutamyltransferase correlated with aspartate aminotransferase, glutamine, and alanine. Prealbumin correlated with albumin and immunoglobulins G and A. Tyrosine correlated with total bile acids, orosomucoid, and 10 amino acids. The amino acid ratio of valine + isoleucine + leucine to tyrosine + phenylalanine was lowered in all patients. It is concluded that the clinical picture and pattern of serum components in patients with alcoholic liver disease are influenced by many complex pathophysiological mechanisms.
