Effects of two different lipid emulsions on morbidities and oxidant stress statuses in preterm infants: an observational study

Abstract Objective: We examined the morbidities and oxidative stress statuses in preterms receiving either SMOFlipid or ClinOleic. Study design: This observational study was performed in Etlik Zubeyde Hanim Hospital, Turkey. Infants received SMOFlipid (5 months) or ClinOleic (7 months). Two hundred and twenty seven infants (SMOFlipid: 93, ClinOleic: 134) very low birth weighted infants were included. The oxidative stress status was evaluated in infants at low risk of oxidative stress by total antioxidant capacity (TAC) and total oxidant status (TOS) and oxidative stress index (OSI; TAC/TOS/100) at baseline, first week and third week. Results: Parenteral nutrition was given for a median of 7 days in both groups. There were statistically insignificantly higher rates of retinopathy of prematurity (9.4 versus 11.7%) and chronic lung disease (4.7 versus 6.7%) in ClinOleic group compared with SMOFlipid group. The TAC, TOS and OSI decreased significantly in ClinOleic group after 1 week, and although the results were not statistically significant, the TAC increased while the TOS and OSI decreased in SMOFlipid group. In both groups, the TAC, TOS and OSI were lower than baseline after 3 weeks. Conclusion: SMOFlipid and ClinOleic result in similar oxidative stress statuses after they were stopped, and we detected no statistically significant differences in morbidity rates.
