Objective.Antibodies that recognize the phosphatidylserine/prothrombin complex (antiphosphatidylserine/prothrombin antibodies; aPS/PT) might reveal enhanced thrombotic risk in patients with systemic lupus erythematosus. Little is known about their association with pregnancy complications in the antiphospholipid syndrome (APS).Methods.We enrolled 55 patients with APS who were seeking pregnancy in 2 Italian hospitals. Antiphospholipid antibodies (aPL), including anticardiolipin antibodies, anti-β2-glycoprotein I antibodies, lupus-like anticoagulant, and aPS/PT antibodies were assessed, and the patients were prospectively followed for 24 months.Results.There were 65% (36/55) of the APS patients who had aPS/PT antibodies. Forty-seven pregnancies were followed, including 33 of aPS/PT+ patients. Forty-one of the 47 patients (87%) who initiated a pregnancy eventually gave birth to a child. The pregnancy duration and the mean newborn weight at delivery were significantly lower in aPS/PT+ than in aPS/PT− patients (33.1 ± 4.7 vs 36.2 ± 3.4 wks of gestation, respectively, and 2058 ± 964 g vs 2784 ± 746 g, respectively, p < 0.05). Late pregnancy complications, including intrauterine fetal death, preterm delivery, preeclampsia, and intrauterine growth restriction (IUGR), were more frequent in aPS/PT+ patients, independent of the therapy. Titers of aPS/PT IgG were significantly inversely correlated with the neonatal weight at delivery. Vascular injury, as reflected by thrombosis, fibrinoid necrosis, ischemic and hemorrhagic areas, and presence of chorangiomas characterized the IUGR placentas in the presence of aPS/PT.Conclusion.The aPS/PT antibodies might represent markers of aPL-related pregnancy complications, IUGR/preeclampsia in particular, and could help identify beforehand patients who may require additional treatment.

Abstract The placenta is the primary organ responsible for deactivating maternal glucocorticoids and reducing fetal exposure. Glucocorticoid use during pregnancy is a common treatment for asthma, allergies, and COVID-19. Several studies have reported adverse effects including intrauterine growth restriction as a result of glucocorticoid exposure, yet little is known about the mechanisms by which short and long-term maternal glucocorticoid exposures affect placental biology and fetal development. To better understand the role of glucocorticoids on placental and fetal outcomes, we used a mouse model exposed to the synthetic glucocorticoid, dexamethasone (Dex), prior to and throughout gestation. We conducted a randomized controlled trial in mice with a treatment arm of Dex exposure and water exposure as control. Virgin C57Bl/6J female mice were single-housed at 11 weeks of age, and Dex was introduced in the drinking water as a 1mg/kg/day dose. After one week of treatment, mice were bred with age-matched virgin males. Dam body composition, food, and water intake were monitored weekly. Maternal insulin sensitivity, pup survival rate, litter size, and pup birth weight at postnatal day (PND) 0.5 were also assessed. Dams treated with Dex lost significant lean mass after one week of treatment. Dex treatment did not appear to affect the dams’ ability to get pregnant, as both groups carried pups to term with similar lengths of gestation (p=0.838). Water and Dex-treated dams gained comparable weight during the first and second trimesters of pregnancy, however, the Dex group gained less lean mass than the water group during the third trimester. At PND0.5, Dex dams had fewer pups with a 40% reduction in litter size (p=0.01) and lighter pups with a 37% reduction in offspring weight (p&lt;0.001), indicating substantial intrauterine growth restriction. All pups of Dex-treated dams died by PND1. Attempts to rescue pups of Dex-dams by cross-fostering with water-treated nursing dams or by feeding the pups 10% glucose at PND0.5 failed by PND1. These results demonstrate a novel finding regarding the chronic use of glucocorticoids before and during conception and pregnancy. The reduction in both pup weight and late-pregnancy maternal weight gain suggests potential growth restriction or placental insufficiency. Further molecular studies during multiple time points of gestation will help elucidate the mechanisms at play.

Data indicate that intrauterine growth restriction (IUGR) in newborns can be partly alleviated through the supply of l-arginine (Arg) and N-carbamylglutamate (NCG).

This study investigated the effect of intrauterine growth restriction (IUGR) during late pregnancy on weight and cellularity of the gastrointestinal tract (GIT) in postnatal lambs. Twenty-three Mongolian lambs were entered into the study. Their dams were mated at a synchronized estrus and divided into three groups offered 0.175 MJ ME kg-0.75 d-1 (Restricted Group 1, RG1), 0.33 MJ ME kg-0.75 d-1 (Restricted Group 2, RG2) and Control Group (CG, ad libitum access to feed) during their late pregnancy (90 d), respectively. The lambs were slaughtered at birth (neonatal lambs) and at 28 wk of age. The neonatal abomasum weight, jejunum weight and length, abomasum and jejunum DNA content, and the reticulum protein:DNA ratio were lower for RG1 than those of CG (P < 0.05). At 28 wk of age, there were no significant difference in the weights and lengths of jejunum and the weight of abomasum in the lambs among RG1, RG2 and CG (P > 0.05). However, the rumen and omasum weight, and omasum DNA content were lower for RG1 than for CG (P < 0.05). For the jejunum, the protein:DNA ratios in RG2 were significantly higher than those of CG (P < 0.05). These changes in the weight and cellularity of the GIT may have significant implications on postnatal growth and health.
