Altered profile of plasma phospholipids in woman with recurrent pregnancy loss and recurrent implantation failure treated with lipid emulsion therapy. Am J Reprod Immunol 2023; 89:e13673.

Abstract
BACKGROUND Recurrent Pregnancy Loss (RPL) and Recurrent Implantation Failure (RIF) are highly heterogeneous condition and many of the mechanisms involved still require elucidation. The aim was to analyze the lipidomic profile in plasma of women with RPL and RIF before and after receiving the Lipid Emulsion Therapy (LET) containing 10% fish oil (SMOFlipid® 20%). METHODS This study included twenty-six women with RPL or RIF from immunological or inflammatory causes, with elevated natural killer cell levels and divided into a Pregnancy Loss or a Live Birth group according to the outcome. The women received intravenous LET and sample collecting was done before the first, third and fifth dose of LET in the pregnant women. Ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-QTOF MS) and multivariate statistical methods were performed to evaluate the profile of phospholipids present in the women's plasma. RESULTS An increase of phosphatidylcholines (PC) 40:8 and 36:5 levels with predominance of n6 polyunsaturated fatty acids (PUFA) was observed in plasma lipids of the Pregnancy Loss Group compared to Live Birth Group. We also observed an increase in the relative abundance of n3 PUFA-PC species (42:10 and 36:6) and LysoPC 15:0 with the long term use of LET. CONCLUSION The greater availability of n3 PUFA in plasma of the pregnant women stemming from LET use can be considered advantageous regarding the alteration of the phospholipid profile and its postulated anti-inflammatory and immunomodulatory role.

The effect of α-linolenic acid enrichment in perinatal diets in preventing high fat diet-induced SCD1 increased activity and lipid disarray in adult offspring of low density lipoprotein receptor knockout (LDLRKO) mice. Prostaglandins Leukot Essent Fatty Acids 2022; 184:102475.

Abstract
The present study examined the effects of maternal perinatal dietary ALA enrichment on the high fat diet (HFD)-induced lipid disarray in the adult offspring of low density lipoprotein receptor knock-out (LDLRKO) mice. Female LDLRKO mice received, during pregnancy and lactation, isocaloric diets with either corn oil, RD, or flax oil, ALA. The weaning offspring was given a regular chow diet for a washout period of eight weeks, which was followed by HFD for eight weeks. Plasma and liver lipids and SCD1 activity were then analyzed. The HFD-fed RD adult offspring had substantially higher plasma cholesterol levels than the HFD-fed ALA offspring (15.7 versus 9.7 mmole/l, p<0.00001) and non-alcoholic fatty liver disease (NAFLD) (65.0 versus 23.9 mg/g lipids, p<0.00001). Liver lipids oleic acid (OA) content and monounsaturated to saturated fatty acids (MUFA/SAT) ratio, were two times lower in RD compared to ALA (p<0.0001). The threefold HFD-induced SCD1 raised activity (p<0.00001), and OA produced from SA, observed in RD adult offspring were prevented by perinatal ALA. In conclusion, the resilience of SCD1 to HFD- induced increased activity may account for the beneficial effects of perinatal ALA dietary enrichment in preventing NAFLD and hypercholesterolemia from occurring in adult LDLRKO offspring mice.
