  • Title: Metronidazole prevention of serum liver enzyme abnormalities during total parenteral nutrition.
    Author: Lambert JR, Thomas SM.
    Journal: JPEN J Parenter Enteral Nutr; 1985; 9(4):501-3. PubMed ID: 2863398.
    Abstract:
    Abnormal serum liver enzymes are common in adults receiving total parenteral nutrition (TPN). The mechanism(s) responsible for these changes is unclear. One hypothesis is that there is overgrowth of intestinal anaerobic bacteria with subsequent toxic effects on the liver from endotoxins and/or bile acids. A retrospective survey of patients receiving TPN was undertaken. The patients were divided into two matched groups. One group had received metronidazole, a drug that suppresses anaerobic bacteria, while the other group had not. The administration of metronidazole during TPN was associated with prevention of the expected rise of serum alkaline phosphatase, gamma glutamyl transpeptidase, and aspartate amino-transferase. This study supports the concept that anerobic intestinal bacteria may be involved in the pathogenesis of liver changes commonly observed during TPN.
