Abstract
Fetal pleural effusion has been reported to be associated with chromosomal abnormalities, genetic syndromes, obstructive uropathy, lymphatic vessel abnormalities such as Noonan syndrome, RASopathy and congenital lymphatic anomalies, thoracic cavity defects, Rh or ABO incompatibility, non-immune hydrops fetalis, infections, congenital cardiac anomalies, metabolic diseases and hematologic diseases such as α-thalassemia. This review provides a comprehensive view of specific and non-specific chromosome aberrations associated with fetal pleural effusion which is useful for genetic counseling and fetal therapy at prenatal diagnosis of fetal pleural effusion.

Ni M, Zhu X, Liu W, Gu L, Zhu Y, Cao P, Gu Y, Xu Y, Dai C, Wu X, Yang Y, Zhou C, Li J. Fetal congenital gastrointestinal obstruction: prenatal diagnosis of chromosome microarray analysis and pregnancy outcomes. BMC Pregnancy Childbirth 2023; 23:503. [PMID: 37422671 DOI: 10.1186/s12884-023-05828-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 07/02/2023] [Indexed: 07/10/2023] Open
Abstract
OBJECTIVE The aim of this study was to investigate the incidence of chromosome anomalies in different types of congenital gastrointestinal obstruction and assess pregnancy outcomes of fetuses with congenital gastrointestinal obstruction. METHODS A total of 64 cases with gastrointestinal obstruction between January 2014 and December 2020 were enrolled in this study. They were divided into three groups according to sonographic images. Group A: isolated upper gastrointestinal obstruction; Group B: isolated lower gastrointestinal obstruction; Group C: non-isolated gastrointestinal obstruction. The rate of chromosome anomalies in different groups was calculated. Pregnant women with amniocentesis were followed up by medical records and telephone. The follow-up included pregnancy outcomes and development of the live born infants. RESULT From January 2014 to December 2020, there were 64 fetus with congenital gastrointestinal obstruction underwent chromosome microarray analysis(CMA), the overall detection rate of CMA testing was 14.1%(9/64). The detection rate of Group A, B and C were 16.2%, 0 and 25.0% respectively. 9 fetuses with abnormal CMA results were all terminated. Among 55 fetuses with normal chromosomes, 10(18.2%) fetuses were not found to have any gastrointestinal obstruction after birth. 17(30.9%) fetuses were diagnosed with gastrointestinal obstruction and underwent surgical treatment after birth, one of which had lower gastrointestinal obstruction combined with biliary obstruction and died due to liver cirrhosis. 11(20.0%) pregnancy were terminated due to multiple abnormalities. 5(9.1%) fetuses were intrauterine death. 3(5.5%) fetuses were neonatal deaths. 9(16.4%) fetuses were lost to follow-up. CONCLUSION It is crucial to understand whether the gastrointestinal tract abnormality is isolated or associated to other findings. The risk of chromosomal abnormalities in fetuses with isolated lower gastrointestinal obstruction is lower than upper gastrointestinal obstruction. While genetic abnormalities excluded, a promising prognosis is expected for fetuses with congenital gastrointestinal obstruction.

[PMID: 35428251 PMCID: PMC9013087 DOI: 10.1186/s12884-022-04665-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 04/07/2022] [Indexed: 12/02/2022] Open
Abstract
Background Wolf-Hirschhorn syndrome (WHS) is a common genetic condition and prenatal diagnosis is difficult due to heterogeneous expression of this syndrome and rather non-specific ultrasound findings. Objective of this study was to examine the prenatal ultrasound findings in fetuses with Wolf-Hirschhorn syndrome (WHS). Methods Retrospective assessment of 18 pregnancies that were seen at three tertiary referral centers (Universities of Bonn, Tuebingen and Nuernberg / Germany). Findings of prenatal ultrasound examinations, genetic results and outcome were compared. Additionally, findings of our study were compared to previous small case series from the literature and then compared to data on postnatal frequencies and abnormalities in affected patients. Results Median gestational age at the time of examination was 23 + 1 weeks’ (range: 13 + 4 to 29 + 1 weeks’) with female-to-male ratio of > 2.5:1. Most frequent ultrasound findings were facial abnormalities, symmetric IUGR and microcephaly that presented in 94.4, 83.3 and 72.2% of cases, respectively. The combination of microcephaly and hypoplastic nasal bone was a particularly characteristic finding. Growth retardation presented in all fetuses > 20 weeks, but not below. Other frequent abnormalities included cardiac anomalies in 50 and single umbilical artery (SUA) in 44.4% of fetuses. Conclusion WHS should be considered in the presence of symmetric IUGR together with microcephaly, hypoplastic nasal bone and facial abnormalities on prenatal ultrasound. Genetic testing by chromosomal microarray analysis (CMA) is strongly recommended in this context.

[PMID: 33826125 DOI: 10.1007/s40291-021-00522-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/06/2021] [Indexed: 10/21/2022]
Abstract
OBJECTIVE To evaluate the clinical value of BACs-on-Beads (BoBs) assay in detection of microdeletion and microduplication syndromes. METHODS A total of 6,814 cases of amniotic fluid cells collected from January 2015 to July 2020 in our hospital were analyzed by chromosomal karyotyping and BoBs assay. Fluorescence in situ hybridization (FISH) or chromosomal microarray analysis (CMA) provided further validation for the cases of microdeletion and microduplication. RESULTS Thirty microdeletion and microduplication syndromes were identified by BoBs with an incidence of ~1/227, including 22q11.2 microduplication (0.044%, 3/6814), DiGeorge I syndrome (0.044%, 3/6814), 17p11.2 microduplication (0.015%, 1/6814), Smith-Magenis syndrome (0.015%, 1/6814), 17p11.2p11.3 microduplication (0.015%, 1/6814), Williams-Beuren syndrome (0.088%, 6/6814), 7q11.2 microduplication (0.029%, 2/6814), DiGeorge II syndrome (0.015%, 1/6814), 18p11.32p11.21 microduplication (0.015%, 1/6814), Wolf-Hirschhorn syndrome (0.029%, 2/6814), 4p16.3 microduplication (0.015%, 1/6814), Langer-Giedion syndrome (0.015%, 1/6814), Miller-Dieker syndrome (0.015%, 1/6814), Cri du Chat syndrome (0.015%, 1/6814), Xp22.31 microdeletion (0.059%, 4/6814), Prader-Willi syndrome (0.015%, 1/6814). High concordance was obtained between BoBs and FISH or CMA. However, only four cases were detected by chromosomal karyotyping. CONCLUSION BoBs assay can rapidly detect microdeletion and microduplication syndromes, which compensates the shortcomings of conventional chromosomal karyotyping and greatly improves the efficiency and accuracy of prenatal diagnosis.
