[Hepatobiliary changes during exclusive parenteral feeding in infants with severe diarrhea].

In order to specify the factors responsible for the hepatic changes occurring during total parenteral nutrition (TPN) and to propose a preventive treatment, 30 infants treated for severe protracted diarrhea were prospectively distributed into 4 groups: I (n = 10): controls; II (n = 7): oral administration of human milk since the 15th day of TPN; III (n = 5): oral metronidazole since the 15th day; IV (n = 8): parenteral antibiotic therapy for septicemia since the 1st day. Contrary to group IV, the first 3 groups were randomly constituted on the 15th day. Liver function tests, bile and serum biliary acids, duodenal flora, hepato-biliary ultrasonography and, in 12 cases, liver histology were sequentially studied. Liver function changes were observed on the 15th day in all groups. An improvement occurred 15 days later in the infants treated, when the control group worsened (p less than 0.02). A significant increase of bile chenodeoxycholic acid levels was observed in the control group only (p less than 0.01), without change in lithocholic acid levels. These results lead the authors to recommend the preventive use of metronidazole or human milk during prolonged TPN in infants.
