Liver function test alterations associated with parenteral nutrition in hospitalized adult patients: incidence and risk factors.

Background: Parenteral nutrition-associated liver dysfunction can be progressive and irreversible, particularly in children and patients with long-term treatment. This study has assessed the incidence of abnormal liver function tests in hospitalized adults during short term parenteral nutrition (PN) and has investigated risk factors for developing alterations of each parameter.

Methods: A prospective cohort study of parenteral nutrition treated patients with preserved liver function at baseline.

[Glutamine use for parenteral nutrition in the critically ill patient: effects on morbimortality].

Objective: To determine the relationship between adding glutamine dipeptides to parenteral nutrition (PN) and morbimortality in the critically ill patient.

Material And Methods: Case-control retrospective study. The cases were patients to whom PN supplemented with 2 g of nitrogen (glutamine) was administered during the period 2001-2004.
