Summary

The purpose of this study is to analyze if the infants who received Primene solution, have lower serum levels of methionine and cysteine and higher serum levels of taurine, we also analyze if the infants who received Primene solution develop TPN-associated cholestasis in a smaller proportion than those who received Trophamine solution.

Clinical Details

Official title: Effect of Two Amino Acid Solutions on Blood Amino Acid Levels and Frequency of Cholestasis in Neonates

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Outcomes Assessor), Primary Purpose: Prevention

Primary outcome: Blood Amino Acid levels and Frequency of Cholestasis in Neonates

Detailed description: Total parenteral nutrition is an essential component of the care of premature and ill infants. Prolonged parenteral nutrition is associated with complications affecting the hepatobiliary system, such as cholelithiasis, cholestasis, and steatosis. The most common of these is total parenteral nutrition-associated cholestasis (TPNAC), that occurs because of reduced bile flow from the liver into the duodenum. Cholestasis causes liver damage and in some cases, death. Infant and neonate are at particular risk for this complication. The incidence of TPNAC ranges from 7. 4 to 84%.

Animal studies have implicated amino acids in the production of cholestasis; whereas studies in human neonates suggest a direct effect of amino acid infusions on the hepatocyte canalicular membrane. An appropriate amino acid solution might compensate for the metabolic immaturity of infants and perhaps reduce total parenteral nutrition associated complications such as cholestasis. Therefore, is important to compare the frequency of cholestasis and blood amino acid concentration during Primene and Trophamine use.
