An Evaluation of Oxidative Status in Serum and Breast Milk of Mothers Giving Birth Prematurely and at Full-Term

Background: Burning fat and carbohydrates to provide energy in biological systems causes the formation of free oxygen species. Objectives: This study aimed to evaluate the oxidative status of serum and breast milk of mothers giving birth prematurely and at full-term. Materials and Methods: The study comprised 50 mothers who gave birth at full-term at more than 38 weeks and 43 mothers who gave birth pre-term at below 32 weeks. On the postnatal 5th day, samples of the mother’s milk and serum were taken and stored at -80°C until the study day. On the study day, the total oxidant and total antioxidant levels were measured using the Erel method and the oxidative stress index (OSI) was calculated. Results: While the total oxidant level and total antioxidant level values of the milk of the premature birth mothers were found to be significantly high compared to those of the full-term birth mothers (P = 0.001), no statistically significant difference was found in the oxidative stress index values (P > 0.05). No statistically significant difference was found in the total oxidant level and oxidative stress index values of the serum of the premature birth mothers compared to those of the full-term birth mothers, while the total antioxidant level was found to be significantly low (P = 0.04). Conclusions: The oxidants and antioxidants in the milk of mothers giving birth prematurely were found to be significantly higher than those of full-term birth mothers. This can be evaluated as the milk of the premature birth mothers providing increased antioxidant defense to protect the infant.

High-Dose Oral Ibuprofen in Treatment of Patent Ductus Arteriosus in Full-Term Neonates

Background: Patent ductus arteriosus (PDA) is an important risk for heart failure due to left to right shunt in term neonates. Objectives: In this study, we evaluated the effect of high dose ibuprofen in closure of PDA in term neonates. Patients and Methods: We used double dose ibuprofen (20 mg/kg, 10 mg/kg, and 10 mg/kg) for 3 - 30 day old term neonates with PDA who were admitted in the neonatal wards of Shiraz University of Medical Sciences. The results of this study were compared to the data of the previous study in our center which used the low dose of ibuprofen (10 mg/kg, 5 mg/kg, and 5 mg/kg). Results: 29 full term neonates received high-dose ibuprofen, in 18 neonates, PDA was closed after 4 days (62.1% versus 43.3% for the standard dose and 4.7% for the control group in the previous study) (P = 0.001). The results showed no significant correlation between the closure rate and gestational age, postnatal age, sex, and weight. In the 4th day of treatment, size of the pulmonic end of ductus arteriosus decreased from 2.09 mm to 0.77 mm compared to 1.68 mm to 0.81 mm in the standard dose of oral ibuprofen and 2.1 mm to 1.4 mm in the control group (P = 0.046). Conclusions: This study indicated that high-dose oral ibuprofen was more effective in closing or decreasing the size of PDA.
