{"title":"Noninvasive prenatal testing: the future is now.","authors":"Errol R Norwitz, Brynn Levy","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Prenatal detection of chromosome abnormalities has been offered for more than 40 years, first by amniocentesis in the early 1970s and additionally by chorionic villus sampling (CVS) in the early 1980s. Given the well-recognized association between increasing maternal age and trisomy,1-3 the primary utilization of prenatal testing has been by older mothers. This has drastically reduced the incidence of aneuploid children born to older mothers.4 Although younger women have relatively low risks of conceiving a child with aneuploidy, the majority of pregnant women are in their late teens, 20s, and early 30s. As such, most viable aneuploid babies are born to these younger mothers.5 Invasive prenatal diagnosis (CVS and amniocentesis) is not a feasible option for all low-risk mothers, as these procedures carry a small but finite risk and would ultimately cause more miscarriages than they would detect aneuploidy. For this reason, a number of noninvasive tests have been developed-including first-trimester risk assessment at 11 to 14 weeks, maternal serum analyte (quad) screening at 15 to 20 weeks, and sonographic fetal structural survey at 18 to 22 weeks-all of which are designed to give a woman an adjusted (more accurate) estimate of having an aneuploid fetus using as baseline her a priori age-related risk. Ultrasound and maternal serum analysis are considered screening procedures and both require follow up by CVS or amniocentesis in screen-positive cases for a definitive diagnosis of a chromosome abnormality in the fetus. The ability to isolate fetal cells and fetal DNA from maternal blood during pregnancy has opened up exciting opportunities for improved noninvasive prenatal testing (NIPT). Direct analysis of fetal cells from maternal circulation has been challenging given the scarcity of fetal cells in maternal blood (1:10,000-1:1,000,000) and the focus has shifted to the analysis of cell-free fetal DNA, which is found at a concentration almost 25 times higher than that available from nucleated blood cells extracted from a similar volume of whole maternal blood. There have now been numerous reports on the use of cell-free DNA (cfDNA) for NIPT for chromosomal aneuploidies-especially trisomy (an extra copy of a chromosome) or monosomy (a missing chromosome)-and a number of commercial products are already being marketed for this indication. This article reviews the various techniques being used to analyze cell-free DNA in the maternal circulation for the prenatal detection of chromosome abnormalities and the evidence in support of each. A number of areas of ongoing controversy are addressed, including the timing of maternal blood sampling, the need for genetic counseling, and the use of confirmatory invasive testing. Future applications for this technology are also reviewed. </p>","PeriodicalId":21170,"journal":{"name":"Reviews in obstetrics & gynecology","volume":"6 2","pages":"48-62"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3893900/pdf/RIOG006002_0048.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32064817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients should be fully counseled regarding the potential adverse fetal outcomes, including prematurity and low birth weight. Transplant recipients are at an increased risk for both maternal and neonatal complications and should be seen by a high-risk obstetrician in conjunction with their transplant teams. Ideally, preconception counseling begins during the pretransplantation evaluation process. Initiating contraception early after transplantation is ideal, and long-acting reversible methods such as intrauterine devices and subdermal implants may be preferred. Pregnancy should be avoided for at least 1 year after transplantation to limit the potential risks of early pregnancy that may adversely affect both allograft function and fetal well-being. Hypertension, diabetes, and infection should be monitored and treated to minimize fetal risks during pregnancy. Maintenance of current immunosuppression is usually recommended, with the exception of mycophenolic acid products, which (when possible) should be discontinued before conception and replaced with an alternative medication. Throughout pregnancy, immunosuppression must be maintained at appropriate dosing to avoid graft rejection. During labor and delivery, cesarean delivery should be performed for obstetric reasons only. A multidisciplinary team should manage pregnant transplant recipients before, during, and following pregnancy. Breastfeeding and long-term in utero exposure to immunosuppressants for offspring of transplant recipients continue to require further investigation but have been encouraged by recent reports. Continued reporting of post-transplantation pregnancy outcomes to the National Transplantation Pregnancy Registry is highly encouraged. </p>","PeriodicalId":21170,"journal":{"name":"Reviews in obstetrics & gynecology","volume":"6 3-4","pages":"116-25"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4002187/pdf/RIOG006003_0116.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32339354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
