To identify the factors predictive of development of TPN-related cholestasis, we conducted a historical cohort analysis of 62 VLBW infants who received TPN of which 17 developed cholestasis (27.4%). In the cholestatic group, the mean duration of TPN administration was significantly longer (25.7 days vs 8 days, p less than 0.001), the maximum daily amino-acids and lipids in the TPN infusate was significantly higher (amino-acids 2.25 vs 1.25 gm/kg/day, p less than 0.001; lipids 2.0 gm/kg/day vs 1.25 gm/kg/day, p less than 0.01), the duration of fasting was significantly longer (20.7 days vs 6.3 days, p less than 0.001) and the incidence of necrotizing enterocolitis was significantly higher (58.8% vs 15.5%, p 0.02). Using a linear discriminant analysis model with development of cholestasis as the dependent variable, the duration of TPN (p 0.0000) and the maximum daily amino-acid in infusate (p 0.0000) were found to be independent variables predictive of development of cholestasis. This model may serve to identify VLBW infants who will develop cholestasis during TPN.

D010289	Parenteral Nutrition, Total	The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.

D011237	Predictive Value of Tests	In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
