Critchlow E, Wodoslawsky S, Makhamreh MM, Rice SM, Turan OM, Firman B, McLaren R, Araji S, Al-Kouatly HB. Maternal outcomes of a cohort of pregnancies affected by non-immune hydrops fetalis. Int J Gynaecol Obstet 2024; 165:318-327. [PMID: 37897049 DOI: 10.1002/ijgo.15207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 09/09/2023] [Accepted: 10/08/2023] [Indexed: 10/29/2023]
Abstract
OBJECTIVE To describe the maternal outcomes of a prospective cohort of non-immune hydrops fetalis (NIHF) pregnancies with negative standard-of-care evaluations. METHODS This study was a secondary analysis of a prospective cohort study of NIHF pregnancies with negative work-ups (infection, alloimmune anemia, fetomaternal hemorrhage, and chromosomal disorders). Outcomes were obstetric complications, including pre-eclampsia, mirror syndrome, preterm birth, polyhydramnios, postpartum hemorrhage, and maternal mental health. RESULTS Forty pregnancies were included. Four patients developed pre-eclampsia (4/40, 10.0%); three occurred postpartum. None was diagnosed with mirror syndrome. Of the 31 continued pregnancies, 16 (51.6%) resulted in early fetal death or stillbirth and 15 (48.4%) resulted in live births. Of the 15 live births, 8 (53.3%) were delivered by primary cesarean delivery; 5 (62.5%) were for hydrops fetalis. Eleven live births (73.3%) were delivered preterm; 9 (81.8%) were indicated, most commonly for fetal indications (7/9, 77.8%). Polyhydramnios occurred in 14/40 (35.0%) cases. Where EBL was recorded (n=37), there were 5 (13.5%) cases of postpartum hemorrhage and an additional 3 (8.1%) had uterine atony without hemorrhage. Eighteen patients (18/40, 45.0%) had new-onset or exacerbated depression or anxiety symptoms. CONCLUSION Our study identified several important adverse outcomes of pregnancies complicated by NIHF with negative standard-of-care evaluations, including a high rate of postpartum pre-eclampsia and worsened mental health. We identified a higher rate of cesarean delivery and preterm birth, both primarily for fetal indications. We also observed the known relationship between polyhydramnios, hemorrhage, and atony, but noted that this risk included pregnancies concluding in dilation and evacuation. Counseling after a diagnosis of NIHF should include these adverse outcomes.

Abstract
OBJECTIVE Nonimmune hydrops fetalis (NIHF) is associated with poor perinatal outcomes including preterm birth (PTB). However, the frequency and causes of PTB in this population are not well understood. We hypothesized that NIHF frequently results in PTB due to medically indicated delivery for fetal distress. STUDY DESIGN This was a secondary analysis of a prospectively enrolled cohort of pregnancies with NIHF that underwent exome sequencing if standard testing was nondiagnostic. The primary outcome was frequency of PTB at <37 weeks' gestation. Secondary outcomes were reasons for PTB, fetal predictors of PTB, and frequency of neonatal death following PTB. RESULTS Fifty-six cases were included, with a median gestational age at delivery of 32.8 weeks (interquartile range [IQR]: 30.3-35.0). Overall, 86% (48/56) were delivered preterm. Among 48 PTBs, 18 (38%) were spontaneous, 9 (19%) were medically indicated for maternal indications (primarily preeclampsia), and 21 (44%) were medically indicated for fetal indications (nonreassuring antenatal testing or worsening effusions). Neither fetal genetic diagnosis nor polyhydramnios was associated with PTB. CONCLUSION More than four-fifths of pregnancies with NIHF result in PTB, often due to nonreassuring fetal status. These data are informative for counseling patients and for developing strategies to reduce PTB in pregnancies with NIHF. KEY POINTS · Pregnancies complicated by nonimmune hydrops fetalis often result in preterm birth.. · Preterm birth in these cases is most often medically indicated for fetal benefit.. · Fetal genetic conditions and polyhydramnios may be associated with preterm birth in cases of NIHF..

Abstract
Objective: The study aims to evaluate the etiological distribution and prognosis of newborn infants with hydrops fetalis (HF). Methods: All infants born in our hospital within the past 10 years and hospitalized with the diagnosis of HF were included in this retrospective descriptive study. Demographic characteristics, etiological distributions, treatment interventions, and prognosis information of the infants were recorded retrospectively. Infants with incomplete data were excluded from the study. Results: The mean gestational age of infants with HF was 33.6±3.1 weeks, and the mean birth weight was 2444±792 grams. Of the HF cases, 90.5% were born by cesarean section and the prenatal diagnosis rate was 42.9%. About 57.1% of the infants were intubated during resuscitation at birth in the delivery room. In the NICU, 81% of the cases were intubated and 71.4% received surfactant treatment. The most common HF findings were ascites (81%) and subcutaneous edema (81%). The most common interventional procedures were paracentesis (81%) and thoracentesis (52.4%). Exchange transfusion was performed in 2 cases (9.5%) due to immune HF. The mortality rate in the study group was 52.4%. Considering the etiological distribution of HF cases in the study group, three cases were diagnosed with immune HF (14.3%) and 18 cases with non-immune hydrops fetalis (NIHF) (85.7%). The underlying cause in immune HF cases was rhesus incompatibility. In cases with NIHF, idiopathic (23.8%) and cardiovascular diseases were the most common etiologies. A significant relationship was found between delivery room management and mortality. While the need for intubation in delivery room was significantly higher in non-survivors, the frequency of applying only positive pressure ventilation in the delivery room was significantly higher in survivors. While the rate of survival was 66.7% in immune HF cases, it was 44.4% in NIHF cases. Conclusion: The risk of perinatal mortality in infants with HF is high depending on the underlying cause. In this study, it was determined that HF mostly developed for non-immune reasons, prenatal diagnosis and follow-up were insufficient and the interventions performed in the delivery room were an important factor in predicting mortality in the follow-up of neonates with HF.

Abstract
Introduction Hydrops fetalis (HF) is a life-threatening condition in which a fetus has an abnormal collection of fluid in the tissue around the lungs, heart, abdomen, or under the skin. Based on its pathophysiology, it is classified into immune and non-immune types. With the widespread use of anti-D immunoglobulin, non-immune HF has become more common, with an incidence of one in 1,700-3,000 live births. A multitude of fetal diseases with various causes can lead to non-immune HF. Due to the recent advances in prenatal diagnostic and therapeutic interventions together with improved neonatal intensive care, the diagnosis and subsequent management of HF have been refined. However, HF is still associated with a high mortality rate. A recent assessment of the literature found that there is a lack of data on prognostic variables in neonates with HF from low- and middle-income countries. In light of this, we sought to establish the etiologic causes, predictors of mortality, and eventual fate of newborns born non-immune HF at the Aga Khan University Hospital, Karachi during the 10-year period spanning January 2009-December 2019 in this retrospective analysis. Methodology For this study, we collected data from the computerized database and patient record files at the hospital on all infants with non-immune HF. Demographic data, postnatal interventions, clinical and laboratory findings, outcomes, and the results of comparison between HF patients who died and those who survived were analyzed. Results The incidence of non-immune HF at our hospital was 0.62/1,000 live births during the period under study, with 33 newborn babies diagnosed with non-immune HF from a total of 53,033 live-born deliveries. An etiologic factor was discovered in 17 (51.5%) neonates with non-immune HF while 16 (48.4%) were classified as those with unidentified etiology. The most common causes were cardiovascular and genetic syndromes, which resulted in 100% mortality. The overall mortality rate was 67%. The need for mechanical ventilation, surfactant therapy, and prolonged hospitalization were identified as independent risk factors of mortality. Conclusion Our study proves that the need for mechanical ventilation [moderate to severe hypoxic respiratory failure (HRF)] and prolonged hospitalization are strong predictors of poor outcomes in neonates with non-immune HF. Therefore, severe hydrops causing significant mortality can be anticipated based on the patients' respiratory status and the need for escalated oxygen support.

Abstract
We performed a systematic review of the literature to evaluate the incidence and types of lysosomal storage disorders (LSD) in case series of nonimmune hydrops fetalis (NIHF). PubMed, Ovid, and clinicaltrials.gov were reviewed for case series evaluating the workup of NIHF diagnosed in utero or in the neonatal period in human subjects from 1979 to August 2020. Retrospective case series with at least five cases of fetal and/or neonatal NIHF with its workup mentioned were identified. Idiopathic NIHF was defined as NIHF without an apparent cause after initial standard-of-care workup. In total, 22 case series with 2678 total cases of NIHF were identified. The overall incidence of LSD was 6.6% (177/2663) in NIHF cases that were tested for any LSD, and 8.2% (177/2151) in idiopathic NIHF cases. The most common LSD identified in cases of NIHF were mucopolysaccharidosis type VII, galactosialidosis, infantile sialic acid storage disease, Gaucher disease, GM1 gangliosidosis, and sialidosis. More than 40% of the most common LSD causes of NIHF have a potential postnatal treatment. LSD testing for NIHF allows for early diagnosis, better counseling and appropriate management, planning for possible early treatment, and counseling for recurrence risk.

Abstract
Objective To evaluate the clinical profile and outcome of neonates with non-immune hydrops (NIH). Methods Data of all the NIH cases admitted to neonatal intensive care unit at our center, New Delhi from January, 2010 to October, 2017 were extracted from hospital records, which included clinical profile and outcomes. Results Of the 17,299 total births, 27 neonates were identified to have NIH. Antenatal interventions were undertaken in five (18.5%) cases. The most common etiology of NIH was cardiac (n=5; 18.5%). Two babies with chylothorax were successfully managed with octreotide infusions. Overall survival rate of NIH was 70.3% (n=19). All neonates with a suspected genetic syndrome died. Conclusion Multidisciplinary team including obstetricians, pediatric surgeons, geneticists and neonatologists can improve outcome in neonates with NIH.

Abstract
OBJECTIVE To describe the aetiologies and outcomes of pregnancies complicated by hydrops fetalis (HF). STUDY DESIGN Case series of all pregnancies complicated by HF managed at The Royal Women's Hospital (RWH), Melbourne, Australia, between 2001 and 2012. Multiple pregnancies, and cases where antenatal care was not provided at RWH were excluded. Cases were identified from neonatal and obstetric databases. Data were extracted from maternal and neonatal case files, electronic pathology and radiology reports, and obstetric and neonatal databases. RESULTS Over 12 years, 131 fetuses with HF with a median (IQR) gestational age (GA) at diagnosis of 24 (20-30) weeks were included in the analysis. There were 65 liveborn infants with a median (IQR) GA at birth of 33 (31-37) weeks and a median (IQR) birthweight Z-score of 1.4 (0.4-2.2). Overall survival from diagnosis was 27% (36/131) increasing to 55% (36/65) if born alive. CONCLUSIONS The perinatal mortality risk for fetuses and newborn infants with HF is high with important differences dependent on underlying diagnosis and the time at which counselling is provided. Clinicians need to be aware of the outcomes of both fetuses and neonates with this condition.

Abstract
OBJECTIVE To evaluate the incidence, etiology, and 1-year mortality of nonimmune hydrops fetalis (NIHF) and to identify risk factors for mortality in a contemporary population-based dataset. STUDY DESIGN The California Office of Statewide Health Planning and Development maintains a database linking maternal and infant hospital discharge, readmissions, and birth and death certificate date from 1 year before to 1 year after birth. We searched the database (2005-2012) for infants with NIHF (identified by the International Classification of Diseases, 9th Revision, Clinical Modification code). Hazard models were used to identify risk factors for mortality in infants with NIHF; results are presented as hazard ratios (HRs, 95% CI). RESULTS The incidence of NIHF was 2.5 out of 10 000 among live born infants. Neonatal mortality was 35.1% (364 out of 1037) and overall mortality was 43.2% (448 out of 1037) at 1 year of age. Gestational age (GA) was predictive of mortality with a HR of 2.4 (95% CI 1.9-3.2) for preterm compared with term infants. The GA-adjusted HR for mortality was 1.3 (95% CI 1.1-1.6) for polyhydramnios and 1.5 (95% CI 1.2-2.0) for large for gestational age infants compared with appropriate for GA infants. Aneuploid infants with critical congenital heart disease had an adjusted HR of 2.3 (95% CI 1.5-3.6) compared with euploid infants without a structural birth defect. CONCLUSIONS In this large, population-based study, prematurity, polyhydramnios, and large for gestational age were predictors of increased mortality. Mortality is highly variable among euploid and aneuploid infants with and without structural birth defects and critical congenital heart disease.

Abstract
We performed a systematic review of the literature to evaluate the incidence and types of lysosomal storage disorders (LSDs) in case series of nonimmune hydrops (NIH). PubMed and Ovid were reviewed for case series evaluating the workup of NIH diagnosed in utero or in the neonatal period in human subjects. Search terms were as follows: nonimmune hydrops, non immune hydrops, metabolic genetic disorders, and lysosomal storage disorders. The time period searched was 1979 through January 2014. Retrospective case series with at least 5 cases of fetal and/or neonatal NIH with its workup mentioned were identified. Idiopathic NIH was defined as NIH without an apparent cause after an initial workup. Exclusion criteria included studies published in languages other than English and review articles. The 3 authors screened all abstracts and manuscripts independently. Metaanalysis of Observational Studies in Epidemiology guidelines were followed. Fifty-four case series with 678 total cases of NIH were identified. The overall incidence of LSD was 5.2% (35 of 678) in all NIH cases that tested for any LSD and 17.4% (35 of 201) in idiopathic NIH cases. The 3 most common LSDs identified in cases of NIH, in order of decreasing incidence, were Mucopolysaccharidosis type VII, Gaucher's disease, and GM1-gangliosidosis. LSDs occur in 5.2% of all NIH cases and in 17.4% of idiopathic NIH cases and so should be screened for in this clinical scenario. Additionally, if a comprehensive LSD workup is completed on idiopathic cases, 29.6% of those would be reclassified as LSD. LSD testing does not only allow diagnosis but also ensures better counseling, appropriate management, and planning for possible early intervention. Moreover, their detection may aid in a prenatal diagnosis in subsequent pregnancies.

Abstract
OBJECTIVE Nonimmune hydrops is the presence of ≥2 abnormal fetal fluid collections in the absence of red cell alloimmunization. The most common etiologies include cardiovascular, chromosomal, and hematologic abnormalities, followed by structural fetal anomalies, complications of monochorionic twinning, infection, and placental abnormalities. We sought to provide evidence-based guidelines for the evaluation and management of nonimmune hydrops fetalis. METHODS A systematic literature review was performed using MEDLINE, PubMed, EMBASE, and Cochrane Library. The search was restricted to English-language articles published from 1966 through June 2014. Priority was given to articles reporting original research, although review articles and commentaries also were consulted. Abstracts of research presented at symposia and scientific conferences were not considered adequate for inclusion in this document. Evidence reports and guidelines published by organizations or institutions such as the National Institutes of Health, Agency for Health Research and Quality, American Congress of Obstetricians and Gynecologists, and Society for Maternal-Fetal Medicine were also reviewed, and additional studies were located by reviewing bibliographies of identified articles. Grading of Recommendations Assessment, Development, and Evaluation methodology was employed for defining strength of recommendations and rating quality of evidence. Consistent with US Preventive Task Force guidelines, references were evaluated for quality based on the highest level of evidence. RESULTS AND RECOMMENDATIONS Evaluation of hydrops begins with an antibody screen (indirect Coombs test) to determine if it is nonimmune, detailed sonography of the fetus(es) and placenta, including echocardiography and assessment for fetal arrhythmia, and middle cerebral artery Doppler evaluation for anemia, as well as fetal karyotype and/or chromosomal microarray analysis, regardless of whether a structural fetal anomaly is identified. Recommended treatment depends on the underlying etiology and gestational age; preterm delivery is recommended only for obstetric indications including development of mirror syndrome. Candidates for corticosteroids and antepartum surveillance include those with an idiopathic etiology, an etiology amenable to prenatal or postnatal treatment, and those in whom intervention is planned if fetal deterioration occurs. Such pregnancies should be delivered at a facility with the capability to stabilize and treat critically ill newborns. The prognosis depends on etiology, response to therapy if treatable, and the gestational age at detection and delivery. Aneuploidy confers a poor prognosis, and even in the absence of aneuploidy, neonatal survival is often <50%. Mirror syndrome is a form of severe preeclampsia that may develop in association with fetal hydrops and in most cases necessitates delivery.

[PMID: 24094760 DOI: 10.1016/j.pedneo.2013.07.008] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2012] [Revised: 06/11/2013] [Accepted: 07/03/2013] [Indexed: 01/30/2023] Open
Abstract
AIM We aimed to define the etiologic and prognostic factors in live-born infants with hydrops fetalis (HF) in our tertiary neonatal intensive care unit over a 10-year period. METHODS Medical records of newborn infants with HF during 2002-2011 were reviewed retrospectively. Demographic data, prenatal interventions, clinical and laboratory findings, outcomes, and the results of postmortem examinations were analyzed. RESULTS During the study period, 62 newborn infants with HF were identified from 16,200 live-born deliveries and the incidence of HF was 3.8/1000 live births in our hospital. Twenty-eight infants (45.2%) had immune HF, whereas 34 (54.8%) had nonimmune HF. An etiologic factor could be identified in 24 (70.5%) infants with nonimmune HF. Lymphatic dysplasias comprised the majority (23.5%) of the infants with nonimmune HF. Mortality rate was 50%. The presence of two or more serous cavity effusions and gestational age were independently associated with the risk of mortality. CONCLUSION Despite the improvements in neonatal care, mortality rate in infants with HF is still high. Gestational age and the extent of serous cavity determine the risk of mortality. Timely and advanced prenatal or postnatal new therapeutic strategies may alter this fatal outcome in appropriate patients.

Abstract
OBJECTIVE The aim of this study is to outline the aetiology and outcome of a series of fetuses with non-immune hydrops (NIH), detected prenatally. The findings are compared with a comprehensive review of recent reports. METHODS This is a retrospective study reviewing all pregnancies complicated by NIH in the fetus and continued after 20 weeks of pregnancy over a period of 10 years. Outcome was obtained from postmortem reports, discharge summaries, communication with the clinicians or information from the parents. A literature search was also performed to identify all reports on NIH in the last 10 years. RESULTS Seventy-one fetuses affected by NIH were included in this study. The aetiology of the NIH was identified prenatally in 40 cases. The most common causes of NIH were thoracic disorders, infections and cardiovascular disorders. Forty-four of the 71 (62%) fetuses were live-born. There were 10 neonatal deaths. Of the remaining 34 babies, 17 infants survived without morbidity. CONCLUSION The survival rate of NIH is at least 48% in this study. Prenatal identification of the cause is possible in 56% of cases. The risk of neurodevelopmental delay in those that survive is 3 of 28 (11%).

Abstract
OBJECTIVES The objectives were (1) to identify the causes for hydrops fetalis neonates admitted for neonatal intensive care with the diagnosis of hydrops fetalis and (2) to identify the risk factors associated with death. METHODS A retrospective review of a large national data set was performed. RESULTS There were a total of 253,651 discharges from 162 NICUs in the database; 598 patients were identified with a report of hydrops fetalis. The most common associated diagnoses were congenital heart problems (13.7%), abnormalities in heart rate (10.4%), twin-to-twin transfusion (9%), congenital anomalies (8.7%), chromosomal abnormalities (7.5%), congenital viral infections (6.7%), congenital anemia (5%), and congenital chylothorax (3.2%). Of those 598 neonates, 115 were transferred either to another hospital or to another service, 215 died before discharge, and 267 were discharged from the hospital. One patient did not have a discharge type listed and was not included in the outcome analysis. Mortality rates were highest among neonates with congenital anomalies (57.7%) and lowest among neonates with congenital chylothorax (5.9%). Factors that were associated independently with death in logistic regression analyses were younger gestational age, low 5-minute Apgar score, and need for high levels of support during the first day after birth (higher levels of inspired oxygen support and more often treated with high-frequency ventilation). CONCLUSIONS The risk of death among neonates with hydrops fetalis depends on the underlying diagnosis and is highest for those who are born more prematurely and those who are most ill immediately after birth. Information from this large study should prove useful for planning prospective studies and providing prenatal counseling to parents with an affected fetus.

Abstract
Introduction: Recurrent non-immune fetal hydrops (NIH) has been reported in the literature but is a rare entity, with fewer than 6 reported cases so far. It has been postulated to be related to a recessive gene.
Clinical Picture: We report a case of recurrent fetal hydrops in a multigravida with no medical history of note. She presented in her current pregnancy with a significant history of having 4 (out of 7) previous pregnancies affected by hydrops.
Treatment: All the affected pregnancies resulted in mid-trimester pregnancy termination (MTPT) following diagnosis in the second trimester. Previous investigations for hydrops did not yield any obvious cause.
Outcome: Her most recent pregnancy was unaffected. We discuss the possible differential diagnoses and the likelihood of autosomal recessive metabolic diseases being the aetiological factor.
Conclusion: Rare causes of fetal hydrops need to be excluded in cases of recurrent non-immune hydrops with no obvious aetiology following routine investigations.

Abstract
Six newborns that presented at birth with nonimmune hydrops fetalis and for whom no cause could be found were investigated for the presence of lymphatic dysplasia. Careful analysis led to findings of some degree of lymphatic dysplasia in all patients. This suggests that lymphatic dysplasia may represent at least part of the causes that are responsible for the "idiopathic" form of nonimmune hydrops fetalis. Carefully searching for lymphatic dysplasia in these patients, and if indicated in their relatives, as well as establishing the exact nature of the lymphatic dysplasia must be carried out so as to provide proper genetic counseling to families with nonimmune hydrops.
