AIM: Low birth weight is an important issue due to its dreadful consequences in future. Well prevailing over the world, this is important in view of developing countries. Low birth weight is associated with high neonatal and infant mortality, lower trajectory of growth during childhood and adolescence, increases risk of non-communicable diseases during adult life. Oxidative stress is a major player among the various etiologies. Paraoxonase1 is an important antioxidant defense. Phospholipase is required to release free fatty acids from phosphoglycerides utilized for fetal growth. We conducted the study to look for the predictive value of serum paraoxonase and phospholipase.
METHODS: With binding to Helsinki declaration and approval from Institutional Ethical Committee, we have selected 100 pregnant ladies. Serum PON1 arylesterase (ARE), lactonase (LACT) and serum phospholipase (PL) activities are measured. We used SPSS 20.0 for linear and logistic regression models to assess the predictability of the ARE, LACT and PL for predicting the IUGR.
RESULTS: R value increases in the order of maternal age, maternal weight, phospholipase, arylesterase, lactonase. Logistic regression analysis with different models and with birth weight as dependent factor, maternal age is flagged out as not significant. PL, LACT, ARE emerge out to be good predictors of IUGR.
CONCLUSION: From this study we have concluded that PON1 LACT, ARE and serum PL, could be the newer markers IUGR in maternal serum. IUGR can be predicted beforehand by using PON1 LACT, PON1 ARE and serum phospholipase. This surely will help in timely diagnosis and treatment accordingly of possible adverse pregnancy outcome.
