Objective Intra‐amniotic injection of digoxin is a well‐known method for feticide before inducing a termination of pregnancy (TOP) at 17–24 weeks of gestation. Information on its effectiveness when administered after 24 weeks of gestation is limited. This study evaluated the efficacy of intra‐amniotic digoxin injection for inducing fetal demise within 18–24 hours, at 21–30 weeks of gestation, and its safety. Design Prospective cohort study. Setting Tertiary university medical centre. Population Women at 21–30 weeks of gestation with a singleton pregnancy, admitted for TOP. Methods Intra‐amniotic injection of 2 mg of digoxin was performed 1 day before medical TOP. Fetal heart activity was evaluated by ultrasound for 18–24 hours after the injection. Serum digoxin level and maternal electrocardiogram (ECG) were evaluated 6, 10, and 20 hours after injection. Main outcome measure Frequency of successful fetal demise. Results Fifty‐nine women participated in the study. The mean gestational age was 24+2 weeks (range 21+0–30+0), with 29 (49.2%) beyond 24+0 weeks of gestation. Fetal cardiac activity arrest was achieved in 55/59 cases (93.2%). Normal maternal ECG recordings were noted in all cases. Mean serum digoxin levels 6 and 10 hours after injection were in the therapeutic range (1.3 ± 0.7 ng/l and 1.24 ± 0.49 ng/l, respectively) and below the toxic level (2 ng/l). Extramural delivery following digoxin did not occur. There were no cases of chorioamnionitis. Conclusion Intra‐amniotic digoxin for feticide at 21–30 weeks of gestation in a singleton pregnancy appears effective and safe before TOP at advanced gestational ages. Tweetable abstract This study shows that feticide by intra‐amniotic digoxin injection at 21–30 weeks of gestation appears effective and safe.
PCOS is the most common endocrinopathy in women; associated with obesity and insulin resistance (IR). IR leads to accumulation of advanced-glycation-end-products (AGEs) and their receptor, RAGE. PCOS patients have increased levels of vascular endothelial growth factor (VEGF), interleukin 6/8 (IL-6/8) and anti-Mϋllerian-hormone (AMH). PEDF is a secreted-glycoprotein known for its anti-angiogenic and anti-inflammatory properties. We aimed to elucidate the role of PEDF in the pathogenesis and treatment of PCOS. We used a prenatal PCOS mouse model and fed the female offspring a high-fat diet, inducing metabolic PCOS (met.PCOS) characteristics. Female offspring were divided into three groups: control; met.PCOS; met.PCOS + recombinant PEDF (rPEDF). Met.PCOS mice gained more weight, had elevated serum IL-6 and higher mRNA levels of AMH, PEDF and RAGE in their granulosa cells (GCs) than met.PCOS + rPEDF mice. An in vitro Met.PCOS model in human GCs (KGN) line was induced by prolonged incubation with insulin/AGEs, causing development of IR. Under the same conditions, we observed an elevation of VEGF, IL-6/8 mRNAs, concomitantly with an increase in PEDF mRNA, intracellular protein levels, and an elevation of PEDF receptors (PEDF-Rs) mRNA and protein. Simultaneously, a reduction in the secretion of PEDF from GCs, was measured in the medium. The addition of rPEDF (5 nM) activated P38 signaling, implying that PEDF-Rs maintained functionality, and negated AGE-induced elevation of IL-6/8 and VEGF mRNAs. Decreased PEDF secretion may be a major contributor to hyperangiogenesis and chronic inflammation, which lie at the core of PCOS pathogenesis. rPEDF treatment may restore physiological angiogenesis inflammatory balance, thus suggesting a potential therapeutic role in PCOS.
Problem: Preeclampsia (PE) and intrauterine growth restriction (IUGR) are leading causes of perinatal complications, affecting 8%-10% of all pregnancies. Inflammasomes are suspected to be one of the mechanisms that lead to the process of term and preterm labors. This study evaluated the inflammasome-dependent inflammation processes in placental tissue of women with PE and IUGR. Methods of Study:In this prospective cohort study, 14 women with PE, 15 with placental-related IUGR and 19 with normal pregnancy (NP) were recruited during admission for delivery. Maternal blood was obtained prior to delivery and neonatal cord blood and placental tissue were obtained after delivery.Results: NLRP7 and PYCARD protein expression were higher in placental PE and IUGR samples versus NP samples. Immunostaining revealed that NLRP7 and PYCARD were upregulated in PE and IUGR placental syncytiotrophoblast, stroma and endothelial cells. PYCARD serum levels were significantly higher in women with PE and IUGR. No significant changes were observed in neonatal cord blood.Conclusions: NLRP7 and PYCARD are key inflammatory proteins that are significantly elevated in PE and IUGR. Better understanding their significance may enable them to become markers of prediction or progression of PE and IUGR.
