Performance of the FMF First-Trimester Preeclampsia-Screening Algorithm in a High-Risk Population in The Netherlands.

OBJECTIVE: The aim of the study was to evaluate the performance of the first-trimester Fetal Medicine Foundation (FMF) screening algorithm, including maternal characteristics and medical history, blood pressure, pregnancy-associated plasma protein A and placenta growth factor, crown rump length, and uterine artery pulsatility index, for the prediction of preeclampsia in a high-risk population in the Netherlands. METHODS: This is a prospective cohort including nulliparous women and women with preeclampsia or intrauterine growth restriction in previous pregnancy. We screened patients at 11-14 weeks of gestation to calculate the risk for preeclampsia. The primary outcome was preeclampsia and gestational age at delivery. Performance of the model was evaluated by area under the receiver operating characteristic (ROC) curves (AUCs) and calibration graphs; based on the ROC curves, optimal predicted risk cutoff values for our study population were defined. RESULTS: We analyzed 362 women, of whom 22 (6%) developed preeclampsia. The algorithm showed fair discriminative performance for preeclampsia <34 weeks (AUC 0.81; 95% CI 0.65-0.96) and moderate discriminative performance for both preeclampsia <37 weeks (AUC 0.71; 95% CI 0.51-0.90) and <42 weeks (AUC 0.71; 95% CI 0.61-0.81). Optimal cutoffs based on our study population for preeclampsia <34, <37, and <42 weeks were 1:250, 1:64, and 1:22, respectively. Calibration was poor. CONCLUSIONS: Performance of the FMF preeclampsia algorithm was satisfactory to predict early and preterm preeclampsia and less satisfactory for term preeclampsia in a high-risk population. However, by addressing some of the limitations of the present study, the performance can potentially improve. This is essential before implementation is considered.

Management of osteogenesis imperfecta type I in pregnancy; a review of literature applied to clinical practice.

PURPOSE: Osteogenesis imperfecta (OI) is a rare heritable heterogenous disorder characterized by bone fragility and susceptibility to fractures with a wide spectrum of clinical expression due to defects in collagen type I biosynthesis. The purpose of the review is to highlight the practical norms in pregnancies with osteogenesis imperfecta. METHODS: We carried out a literature review in MEDLINE on OI during pregnancy, focusing on diagnosis, therapy and delivery. We reviewed 28 articles (case reports, original articles and reviews). RESULTS: Pregnant women affected by type I OI should be closely monitored to assess fetal well-being and detect pregnancy-related complications associated with an increased risk for osteoporosis, restrictive pulmonary disease, cephalopelvic disproportion and other problems related to connective tissue disorders. Mode of delivery remains controversial and should be determined on an individual basis. CONCLUSION: In conclusion, women affected by type I OI represent a subset of patients whose pregnancies should be considered high risk and warrant a multidisciplinary approach in a referral center.

Interstitial pregnancy treated with a single-dose of systemic methotrexate: A successful management.

Interstitial pregnancy is an ectopic pregnancy at high hemorrhagic risk. It often poses a diagnostic and therapeutic challenge to the clinician, with a significant risk of morbidity and mortality. It presents a difficult management problem with no absolute standard of care; the most appropriate treatment technique for these pregnancies remains controversial. We describe a case of unruptured interstitial pregnancy successfully treated with a single-dose of systemic methotrexate with subsequent ultrasound and serum beta human chorionic gonadotropin monitoring. Medical management can be a safe and successful option in selected cases that satisfy specific criteria and in women who are able to be monitored after treatment.

Isolated fetal echogenic bowel in a retrospective cohort: The role of infection screening.

OBJECTIVE: Fetal echogenic bowel (FEB) is an ultrasonographic marker of fetal infection. We aimed to determine the utility of infection screening when FEB is isolated. STUDY DESIGN: Retrospective observational study of isolated FEB cases between 2006-2014. Infection screening included toxoplasmosis, rubella, syphilis, cytomegalovirus (CMV), herpes simplex virus and parvovirus B19. Fetal karyotyping, screening for cystic fibrosis (CF) and follow-up scans were also offered, according to international standards. Incidence of infection and 95% confidence interval (CI) were calculated. RESULTS: 148 patients with 154 fetuses were included. 4.7% of mothers developed acute infection: four patients developed CMV infection (2.7%, 95% CI 1.1-6.9%), in two fetuses infection was confirmed with amniocentesis and pregnancies were terminated; Parvovirus B19 infection was detected in 2 patients (1.4%, 95% CI 0.4-5.0) and confirmed in one fetus, which developed anemia; there was one toxoplasmosis maternal infection (0.7%, 95% CI 0.1-3.8%) treated with spyramicin, whose fetus was not infected. Percentage of chromosomal/genetic abnormalities was 3.2%, CF 1.3%, intra-amniotic bleeding 1.3%, FGR 34% and other ultrasonographic abnormalities at follow-up scans 18%. CONCLUSIONS: The association between isolated FEB and fetal infection is uncommon (1.9% in our population). CMV maternal infection screening is supported by our findings, whereas screening for other infections needs to be further investigated.

Association of genetic variants in the 3'UTR of HLA-G with Recurrent Pregnancy Loss.

Human Leukocyte Antigen (HLA)-G is involved in reprogramming immune responses at fetal-maternal interface during pregnancy. We evaluated the genetic diversity of the 3' Un-Translated Region (UTR) of HLA-G, previously associated with HLA-G mRNA post-transcriptional regulation, in women with unexplained Recurrent Pregnancy Loss (RPL), with 2 pregnancy losses (RPL-2, n=28), or 3 or more pregnancy losses (RPL-3, n=24), and in 30 women with a history of successful pregnancy. Results showed in RPL-2, but not in RPL-3, women compared to controls: i) higher frequency of the 14bp Ins allele, in single and in double copy; ii) significantly lower frequency of DelG/X genotype, iii) reduced frequency of the UTR-2, and UTR-3 haplotypes; iv) higher frequencies of the UTR-5, UTR-7, and UTR-8 haplotypes. This pilot study supports the relevance of performing 3'UTR HLA-G genetic screening, not limited to a specific polymorphism, but considering the extended haplotypes, as a possible predictor of pregnancy outcome.

Endometriosis-Related Hemoperitoneum in Pregnancy: A Diagnosis to Keep in Mind.

BACKGROUND: Endometriosis is an important gynecologic clinical entity, pathologically defined by the ectopic presence of endometrium and frequently associated with pelvic pain, that affects approximately 10% of females of reproductive age. A rare but severe complication of endometriosis during pregnancy is spontaneous hemoperitoneum in pregnancy (SHiP), severe intraabdominal bleeding that can be life threatening. CASE REPORT: We present the case of a patient with SHiP at 29 weeks of pregnancy. A supraumbilical midline laparotomy was performed, and pelvic exploration revealed a lacerated and bleeding right ovary. Right annessiectomy was performed, and a cesarean section was performed because hemostasis was not achievable. A healthy baby was born, and hemostasis was finally achieved. CONCLUSION: We believe that in gravid females with a history of endometriosis, severe abdominal pain, and a reduction of hemoglobin, physicians should always suspect SHiP. Because SHiP is a life-threatening condition for both the mother and the baby, a prompt diagnosis must lead to prompt treatment.
