RESUMO
Parenteral nutrition (PN) is a life-sustaining method to provide adequate nutrients to patients unable to receive oral or enteral nutrition. PN typically contains a mixture of macro- and micro-nutrients, although the lipid composition has been identified as a concern for liver disease. Therefore, the study of the intravenous lipid emulsion (ILE) prescribing practices in home-based PN (HPN) patients and whether differing lipid PN alters liver function tests (LFTs) is needed. METHODS: A retrospective study of monthly LFTs from a random sample of 105 adult HPN patients in the U.S. over a 6-month period was conducted. Patients were receiving olive oil/soy oil (n = 53, Clinolipid), mixed ILE (n = 39, SMOF Lipid), soy oil (SO; n = 4, Intralipid), or none (n = 7). LFTs monitored were alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate transaminase (AST), and total bilirubin (T Bili). RESULTS: No differences were observed in baseline LFTs across groups (all, p > 0.25, η2 < 0.04), nor were there differences in age, body mass index, days of PN, or mean PN volume (all, p > 0.36, η2 < 0.05). There were no significant interactions between ILE type and time (all p > 0.64, ηp2 < 0.03), no effect of ILE type (all p > 0.60, ηp2 < 0.03), and no effect of time (all p > 0.69, ηp2 < 0.01) in terms of LFTs. Average LFTs over six months were also not different between ILE types (all p > 0.30, η2 < 0.04). CONCLUSION: These findings suggested that patients were mostly prescribed mixed or ILE PN containing more than one lipid source and that differing ILEs in long-term HPN patients did not alter LFTs over a six-month period.
