Introdução: O conceito de restrição do crescimento fetal tardio (CFT) foi introduzido para descrever fetos com insuficiência placentária que não é grave o suficiente para resultar em CFT com fluxo arterial umbilical anormal, mas é grave o suficiente para associar-se com alto risco perinatal ou complicações de longo prazo. Entretanto, há necessidade de retroceder a investigação para o primeiro trimestre, na esperança de possível intervenção. Objetivo: Realizar revisão bibliográfica do tema. Material e Métodos: As palavras-chave CIUR (crescimento intrauterino restrito) e IUGR (intrauterine growth restriction) foram identificadas na Biblioteca Virtual em Saúde (BVS). O termo CIUR também foi pesquisado na Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS), nos últimos dez anos. Com o auxílio do Endnote, foram realizadas pesquisas no PubMed usando a palavra-chave (MeSH term) intrauterine growth restriction (IUGR), no período 2011‒2020. Os artigos foram baixados e foi montada uma pasta com eles em formato pdf. Posteriormente, foram importados pelo Endnote. Resultados: Na LILACS, nos últimos 10 anos, foram recuperados 20 artigos com texto completo. No PubMed, no período 2011‒2020 (até agosto), foram identificadas 5.551 referências sob o título “intrauterine growth restriction”. Utilizando como filtro a expressão “first trimester”, restaram 370 referências, e após um segundo filtro (“screening”), 308 referências. Destas, conseguimos os textos completos em .pdf de 101, que foram utilizados para a presente revisão. Modelos foram identificados incluindo dados clínicos maternos (método de contracepção, tabagismo, altura materna), métodos de imagem (Doppler da artéria uterina, avaliando o índice de pulsatilidade — PI) e avaliação bioquímica (fator de crescimento placentário — PlGF, gonadotrofina coriônica — βhCG, pregnancy-associated plasma protein-A — PAPP-A, soluble fms-like tytosine kinase — sFlt-1 e disintegrin and metalloprotease — ADAM 12). Conclusão: Neste estudo, foram utilizados diferentes modelos com associação dos fatores mencionados anteriormente. Ainda não se identificou o modelo ideal, necessitando de novos estudos.

Abstract Purpose To evaluate the usability of first-trimester maternal serum ProBNP levels in the prediction of intrauterine growth restriction (IUGR). Methods In this prospective study, blood samples taken from 500 women who applied to our polyclinic for routine serum aneuploidy screening between the 11–14th gestational weeks were centrifuged. The obtained plasma samples were placed in Eppendorf tubes and stored at −80+°C. For the final analysis, first-trimester maternal serum ProBNP levels of 32 women diagnosed with postpartum IUGR and 32 healthy women randomly selected as the control group were compared. FGR was defined as estimated fetal weight below the 10th percentile for the gestational age. Results The mean ProBNP levels were statistically and significantly higher in the women with intrauterine growth restriction (113.73±94.69 vs. 58.33±47.70 pg/mL, p<0.01). At a cut-off level of 50.93, ProBNP accurately predicted occurrence of IUGR (AUC+= 0.794 (95% confidence interval 0.679–0.910), p+= 0.001) with sensitivity and specificity rates of 78.1 and 69.0%, respectively. Conclusion First-trimester serum ProBNP level was significantly higher in women who developed IUGR compared to healthy controls. First-trimester ProBNP level can be used as a potential marker to predict the development of IUGR in pregnant women.

BACKGROUND: Pregnancy-associated plasma protein A (PAPP-A), is a protease which releases Insulin-like growth factor. The role of this factor is stimulation of cell mitosis, differentiation and trophoblastic invasion of deciduas. Identification of patients with low PAPP-A (under 0.4 MoM in the first trimester has an influence on birth weight, attenuation of fetal growth, preeclampsia, birth and fetal demise.AIM: The main issue in the study is evaluating an influence of PAPP-A, calculated in the first trimester on the unfavourable outcome of pregnancy.MATERIAL AND METHODS: Seventy pregnant women with singleton pregnancy underwent first-trimester biochemical screening. The target group were women with PAPP-A below 0.4 MoM, and in control group, PAPP-A were оver 0.4 MoM. There was an assessment of the influence on the mode of delivery, gestational week, the presence of intrauterine growth restriction, preeclampsia, temporary birth, intrauterine fetal demise and newborn condition.RESULTS: In target group, consisted of 35 patients, 16 were delivered at term. From 28 to 37 g.w.- were 7 patient, 22-28 g.w.- 4 and 8 patients were under the 22 g.w (all with fetal demise) there were 19 pretemporary deliveries - 9 with Cesarean Section (SC). In the target group: 5 newborn wеre with IUGR, 6 women had preeclampsia, 1 had placental abruption. In control group were 35 patients: 28 delivered at term, 9 with SC, 26 vaginal deliveries; with IUGR were 4 newborns. Two newborns were hypertrophic.CONCLUSION: There is a significant difference in unfavourable outcome in the cases with PAPP-A under 0.4 Mom, particular in the group, with a PAPP-A value under 0.2 MoM. The patients delivered with SC with the main indications in utero hypoxia, growth restriction and elevated blood pressure had PAPP-A between 0.3-0.4 MoM. The patients with intrauterine fetal death and placental abruption in the most of the cases have PAPP-A value under 0.2 MoM. There is a need to be aware in these pregnancies to achieve the preventions of adverse outcome, to decrease perinatal morbidity and mortality.

IntroductionPre-eclampsia (PE) and intrauterine growth restriction (IUGR) are two major pregnancy complications, related to chronic uteroplacental hypoperfusion. Nowadays, there is no screening or diagnostic test for uteroplacental vascularisation deficiency in pregnant women. Since 2004, 3 three-imensional power Doppler (3DPD) angiography has been used for the evaluation of uteroplacental vascularisation and three vascular indices are usually calculated: Vascularisation Index (VI), Flow Index (FI) and vascularisation-FI (VFI). A high intraobserver and interobserver reproducibility and a potential interest for placental function study were reported by our team and others.The main objective of our study is to determine differences in 3DPD indices at first trimester between pregnancies defined at their outcome as uncomplicated pregnancy, PE (mild and severe) and IUGR in nulliparous women.Methods and analysisThis is a national multicentre prospective cohort study conducted in four French maternity units. We expect to include 2200 women in a period of 36 months. The nulliparous pregnant women will be recruited during their first trimester consultation (11–13+6 gestation week (GW)).The 3DPD and uterine artery Doppler acquisition will be included in the current routine 11–13+6 GW ultrasound. Also, additional blood samples will be taken for biomarker analysis (PAPP-A and P1GF) and biological collection. Uteroplacental VIs (FI and VFI) will be measured. For each subgroup (uncomplicated pregnancy, PE and IUGR), mean values in 3DPD indices will be computed and compared using a pairwise t test with a Bonferroni correction p value adjustment.Ethics and disseminationThe study was approved by the French Ethics Committee, the Comité de Protection des Personnes SUD MEDITERRANEE IV on 13 February 2018 with reference number 17 12 03. The results of this study will be published in a peer-reviewed journal and will be presented at relevant conferences.Trial registration numberNCT03342014; Pre-results. PHRCN-16-0567.
