Insights
This study compared SMOFlipid and ClinOleic in preterm infants, finding similar oxidative stress levels and no significant differences in morbidities like retinopathy of prematurity or chronic lung disease after use.
Area of Science:
- Neonatal Medicine
- Nutritional Science
- Oxidative Stress Research
Background:
- Preterm infants often require parenteral nutrition.
- Evaluating lipid emulsions like SMOFlipid and ClinOleic is crucial for neonatal care.
- Understanding their impact on oxidative stress and morbidities is essential.
Purpose of the Study:
- To compare the effects of SMOFlipid and ClinOleic on oxidative stress markers.
- To assess and compare the incidence of morbidities in preterm infants receiving these lipid emulsions.
Main Methods:
- An observational study involving 227 very low birth weight preterm infants.
- Infants received either SMOFlipid or ClinOleic for parenteral nutrition.
- Oxidative stress was measured using total antioxidant capacity (TAC), total oxidant status (TOS), and oxidative stress index (OSI) at baseline, week 1, and week 3.
Main Results:
- No statistically significant differences in retinopathy of prematurity or chronic lung disease rates between the groups.
- Oxidative stress markers (TAC, TOS, OSI) showed significant decreases in the ClinOleic group after 1 week.
- While not statistically significant, the SMOFlipid group showed a trend towards increased TAC and decreased TOS/OSI.
Conclusions:
- SMOFlipid and ClinOleic demonstrate comparable effects on oxidative stress markers once discontinued.
- No significant differences in key neonatal morbidities were observed between the two lipid emulsions.
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.
