    Abstract:
    AIM: Parenteral nutrition (PN) provides an alternative nutrition source for preterm infants who are intolerant of enteral nutrition. However, prolonged PN increases the risk of PN-associated cholestasis (PNAC). We conducted this study to determine the incidence and risk factors of PNAC in extremely low birth weight (ELBW) infants. METHODS: We retrospectively reviewed the medical records of ELBW infants from March 2010 to April 2015. PNAC was diagnosed in infants with a history of PN for at least two weeks and direct bilirubin concentrations >2 mg/dL after other causes of neonatal cholestasis were excluded. RESULTS: Of the 114 eligible ELBW infants, 41 (36%) were diagnosed with PNAC. The multivariate analysis showed that birth weight, sepsis, necrotising enterocolitis, fluconazole prophylaxis and the duration of PN and hospitalisation were independent risk factors for the development of PNAC (p < 0.05). However, parenteral fish oil-based lipid preparation (FOLP) did not reduce the risk of PNAC. Although PNAC was not a direct cause of death, it was associated with an increased risk of mortality. CONCLUSION: PNAC was common in ELBW infants, was associated with various clinical factors and increased the risk of mortality. However, we did not observe the protective effect of FOLP against PNAC.
