Total parenteral nutrition-related cholestasis in infants.
An epidemiological study was conducted to estimate the proportion of infants on total parenteral nutrition (TPN) who developed cholestasis and to identify risk factors associated with the development of this disease. Data were abstracted from medical records of 624 infants less than or equal to 30 days of age who were treated with TPN. A case of TPN-related cholestasis was defined as an infant whose serum level of direct bilirubin was greater than or equal to 1.5 mg/dl subsequent to initiation of TPN. Risk factors were assessed using multiple logistic regression analysis. Forty-six of 624 infants in the cohort (7.4%) were classified as having TPN-related cholestasis. The multivariable analysis indicated that cholestasis was associated with intracranial hemorrhage, patent ductus arteriosus, sepsis and gastrointestinal conditions that require surgery. Two distinct processes appear to have occurred: in infants who experienced patent ductus arteriosus or intracranial hemorrhage (conditions associated with hypoxia) where TPN may be the necessary trigger for the development of cholestasis, and in infants with gastrointestinal conditions requiring surgery or sepsis, where cholestasis may develop with or without parenteral infusions.
