Ethical issues about the paradigm shift in the treatment of children with trisomy 18

Ethical Implications of Cleft Lip and Palate Repair in Patients with Trisomy 13 and Trisomy 18

BACKGROUND

Children born with Trisomy 13 or 18 (T13/18) often have multiple congenital anomalies, many of which drastically shorten their lifespan. Among these defects are cleft lip and palate, the repair of which presents an ethical dilemma to the surgeon given the underlying comorbidities associated with T13/18. The authors present an ethical discussion and institutional experience in navigating this dilemma.

METHODS

The authors analyzed existing literature on T13 and T18 surgery and mortality. A retrospective study over ten years was also conducted to identify pediatric patients who underwent surgical correction of cleft lip and/or palate secondary to a confirmed diagnosis of T13/18. The authors identified two patients and examined their treatment course.

RESULTS

The authors' review of literature coupled with their institution's experience builds on the published successes of correcting cleft lip and palate in the setting of T13/18. It was found that both patients identified in the case series underwent successful correction with no surgical complications.

CONCLUSION

A careful balance must be struck between improved quality of life, benefits of treatment, and risks of surgery in children with T13/T18. Careful consideration should be given to the medical status of these complex patients. If the remaining medical comorbidities are well managed and under control, there is an ethical precedent for performing cleft lip and palate surgeries on these children. A diagnosis of T13/T18 alone is not enough to disqualify patients from cleft lip/palate surgery.

Cardiac care in trisomy 18: A path to improved outcomes (case report)

Background

Trisomy 18 (also known as Edwards syndrome) is a chromosomal disorder characterized by severe developmental anomalies and cognitive deficits. Cardiac complications are a leading cause of mortality in these patients, and the role of cardiac interventions remains controversial.

Case Presentation

We report a case of a full-term baby girl with trisomy 18, born via elective cesarean section. The neonate presented with pulmonary atresia and a series of other cardiac abnormalities, necessitating immediate intervention. Despite the initial challenges, including a brief episode of desaturation post-intervention, the patient responded positively to a balloon pulmonary valvuloplasty and emergency patent ductus arteriosus stent insertion, illustrating the potential benefits of cardiac interventions in patients with trisomy 18.

Discussion

This case highlights the successful application of cardiac interventions in a patient with trisomy 18, challenging the notion of universally denying such treatments to this population. Our findings suggest that selective interventions can improve quality of life and stabilize the condition, supporting the need for further research to establish clear guidelines for treatment in this demographic.

Conclusion

This case adds to the growing evidence supporting the feasibility and potential benefits of cardiac interventions in patients with trisomy 18, advocating for a more individualized approach to treatment.

Structured Framework for Multidisciplinary Parent Counseling and Medical Interventions for Fetuses and Infants with Trisomy 13 or Trisomy 18

OBJECTIVE

Trisomy 13 (T13) and 18 (T18) are aneuploidies associated with multiple structural congenital anomalies and high rates of fetal demise and neonatal mortality. Historically, patients with either one of these diagnoses have been treated similarly with exclusive comfort care rather than invasive interventions or intensive care, despite a wide phenotypic variation and substantial variations in survival length. However, surgical interventions have been on the rise in this population in recent years without clearly elucidated selection criterion. Our objective was to create a standardized approach to counseling expectant persons and parents of newborns with T13/T18 in order to provide collaborative and consistent counseling and thoughtful approach to interventions such as surgery.

STUDY DESIGN

This article describes our process and presents our resulting clinical care guideline.

RESULTS

We formed a multi- and interdisciplinary committee. We used published literature when available and otherwise expert opinion to develop an approach to care featuring individualized assessment of the patient to estimate qualitative mortality risk and potential to benefit from intensive care and/or surgeries centered within an ethical framework.

CONCLUSION

Through multidisciplinary collaboration, we successfully created a patient-centered approach for counseling families facing a diagnosis of T13/T18. Other institutions may use our approach as a model for developing their own standardized approach.

KEY POINTS

· Trisomy 13 and trisomy 18 are associated with high but variable morbidity and mortality.. · Research on which patients are most likely to benefit from surgery is lacking.. · We present our institution's framework to counsel families with fetal/neonatal T13/T18..

Trisomy 18: disparities of care and outcomes in the State of Texas between 2009 and 2019

OBJECTIVE

To perform a statewide characteristics and outcomes analysis of the Trisomy 18 (T18) population and explore the potential impact of associated congenital heart disease (CHD) and congenital heart surgery.

STUDY DESIGN

Retrospective review of the Texas Hospital Inpatient Discharge Public Use Data File between 2009 and 2019, analysing discharges of patients with T18 identified using ICD-9/10 codes. Discharges were linked to analyse patients. Demographic characteristics and available outcomes were evaluated. The population was divided into groups for comparison: patients with no documentation of CHD (T18NoCHD), patients with CHD without congenital heart surgery (T18CHD), and patients who underwent congenital heart surgery (T18CHS).

RESULTS

One thousand one hundred fifty-six eligible patients were identified: 443 (38%) T18NoCHD, 669 (58%) T18CHD, and 44 (4%) T18CHS. T18CHS had a lower proportion of Hispanic patients (n = 9 (20.45%)) compared to T18CHD (n = 315 (47.09%)), and T18NoCHD (n = 219 (49.44%)) (p < 0.001 for both). Patients with Medicare/Medicaid insurance had a 0.42 odds ratio (95%CI: 0.20-0.86, p = 0.020) of undergoing congenital heart surgery compared to private insurance. T18CHS had a higher median total days in-hospital (47.5 [IQR: 12.25-113.25] vs. 9 [IQR: 3-24] and 2 [IQR: 1-5], p < 0.001); and a higher median number of admissions (n = 2 [IQR: 1-4]) vs. 1 [IQR: 1-2] and 1 [IQR: 1-1], (p < 0.001 for both). However, the post-operative median number of admissions for T18CHS was 0 [IQR: 0-2]. After the first month of life, T18CHS had freedom from in-hospital mortality similar to T18NoCHD and superior to T18CHD.

CONCLUSIONS

Short-term outcomes for T18CHS patients are encouraging, suggesting a freedom from in-hospital mortality that resembles the T18NoCHD. The highlighted socio-economic differences between the groups warrant further investigation. Development of a prospective registry for T18 patients should be a priority for better understanding of longer-term outcomes.

Effectiveness of cardiac palliative surgery for trisomy 18 patients with increased pulmonary blood flow

Congenital heart disease (CHD) is common among patients with trisomy 18 (T18), but cardiac surgery has been rarely indicated for T18 patients due to their short life span. Although the therapeutic effects of aggressive interventions were recently demonstrated for T18 patients, the subjects and factors examined varied, resulting in inconsistent findings. Therefore, the effects of cardiac surgery for T18 remain unclear. We herein investigated the outcomes of cardiac palliative surgery for CHD with increased pulmonary blood flow in T18 patients. 27 patients were examined: 13 (48.1%) underwent cardiac palliative surgery and 14 (51.9%) did not. Median survival times in the no-surgery and surgery groups were 223.0 days (95% confidence interval [CI]: 46-361 days) and 723.0 days (95% CI: 360-1447 days), respectively. The number of patients with pulmonary hypertension significantly differed between the two groups (5 of 14 in the no-surgery group and 0 in the surgery group). Five of 14 patients in the no-surgery group and 10 of 13 in the surgery group were discharged to home care (odds ratio: 10.8 [95% CI: 1.07-110.0]). Therefore, cardiac palliative surgery may be used to treat CHD with increased pulmonary blood flow in T18 patients.

Conducta médica frente al diagnóstico prenatal de trisomía 18: ¿se aproxima un cambio de paradigma?

El objetivo del trabajo es analizar dos conductas médicas opuestas en la vida prenatal de los niños con trisomía 18: el aborto y los cuidados paliativos perinatales. Se realizó una búsqueda bibliográfica en PubMed a partir de los términos “trisomy 18”, “abortion” y “palliative care”. Actualmente, están cambiando las conductas médicas dirigidas a los niños nacidos con trisomía 18, debido a que ya no se la considera una enfermedad incompatible con la vida. Este cambio de paradigma en la conducta médica posnatal debería reflejarse en la conducta prenatal, para ofrecer a los padres alternativas distintas al aborto. Los cuidados paliativos fetales y perinatales constituyen una respuesta ética válida para el tratamiento de niños con trisomía 18.

Attitudes of Argentinean Neonatologists toward Resuscitation of Infants with Trisomies 21, 18, and 13: A Multicenter Survey

OBJECTIVE

This study was aimed to explore the attitude of Argentinean neonatologists in the delivery room on resuscitating infants with trisomies.

STUDY DESIGN

An anonymous questionnaire was completed by neonatologists staffing level-III neonatal intensive care units (NICUs) on resuscitation of children with trisomies 21, 18, and 13. Potential sociocultural factors influencing the decision to resuscitate were included.

RESULTS

Overall, 314 neonatologists in 34 units in the Buenos Aires region participated (response rate of 54%). The position of neonatologists regarding the resuscitation in the delivery room was that 98% would resuscitate newborns with trisomy 21, and 47% with trisomy 18 or trisomy 13. Resuscitation of newborns with trisomy 18 or trisomy 13 by neonatologists was significantly associated with working in the public sector, religious beliefs, and legal framework.

CONCLUSION

With improvement in the management and treatment of infants with trisomies 18 and 13, Argentinean neonatologists showed a favorable attitude toward resuscitating them in the delivery room.

KEY POINTS

· We explored the attitudes of Argentinean neonatologists on resuscitation of children with trisomies.. · Half of neonatologists would resuscitate newborns with trisomies18 and 13.. · These results suggest an ongoing paradigm shift of the most severe trisomies..

Parents' Needs and Their Perceived Obstacles With Team Members in Perinatal Palliative Care: A Qualitative Phenomenological Study

Advances in prenatal diagnosis have made medical, psychological, and ethical issues regarding the diagnosis of fetal anomalies a crucial topic of research. This study identified the needs of parents of unborn babies with fetal anomalies and their views regarding the services of interdisciplinary team members in charge of assisting them. The sample consisted of 30 parents and 40 team members from a women's health education and research hospital. Data were collected through face-to-face interviews and were qualitatively analyzed using the phenomenological method of interpretation. The results showed that parents' physical, psychological, social, and spiritual needs during pregnancy, childbirth, and postpartum were not fully met after their unborn babies were diagnosed with fetal anomalies. The results also showed that team members needed a structured program, legal regulations, and training to provide holistic care.

Trisomy 18-when the diagnosis is compatible with life

Trisomy 18 is an autosomal chromosomal disorder characterized by the presence of an extra 18 chromosome. In the last decades, and as novel therapeutic options emerged, a paradigm shift on the treatments available to these children occurred, establishing the need to deepen the knowledge regarding the management/treatment of children diagnosed with trisomy 18. This retrospective cohort study sought to characterize the clinical path and survival of the children with the diagnosis of trisomy 18 followed in a tertiary pediatric hospital between 1995 and 2020. Medical records were reviewed, and epidemiological and clinical features and follow-up data were collected. Six patients were identified, two with mosaicism (33.3%) and four were female (66.7%). All had cardiovascular, cognitive, and physical development anomalies or minor congenital anomalies. Most presented neurological anomalies (n = 4, 66.7%) and feeding difficulties (n = 4, 66.7%). Four children (66.7%) required medical devices or equipment and all required chronic medication. Two children (33.3%) underwent surgical interventions. Four children (66.7%) were hospitalized in the last year of life. Three patients had a do not resuscitate order (50%) but only one child was referred to a pediatric palliative care team (16.7%). One-month, 1-year, and 10-year survival were 66.7% (n = 4), 33.3% (n = 2, both with mosaicism), and 16.7% (n = 1, with mosaicism) respectively.

CONCLUSIONS

Knowledge of the multiple comorbidities and complex care needs of children with this syndrome is crucial. Every-day care and decisions about invasive treatments may raise ethical issues. Early referral to pediatric palliative care teams is essential to promote a holistic advanced care plan for both the patient and his family.

WHAT IS KNOWN

• The increase in survival and the high morbimortality that trisomy 18 still entails demands a careful deliberation on the use of invasive treatment.

WHAT IS NEW

• Recent studies show that the labels of "incompatible with life"/"lethal" are not adequate, establishing a need to change this mindset. • The development of pediatric palliative care teams in the last decade and early referral allow for an optimal individualized advanced care plan. Under-referral to pediatric palliative care teams persists and efforts must be made to increase awareness of their existence and role in patient care.

New Challenges with Treatment Advances in Newborn Infants with Genetic Disorders and Severe Congenital Malformations

Advances in the prognosis of relevant syndromes and severe congenital malformations in infants during the last few decades have enabled the treatment and survival of an ever-increasing number of infants, whose prospects were previously judged futile by professional health care teams. This required detailed counselling for families, which frequently started before birth when a diagnosis was made using genetic testing or ultrasound. Predictions of the estimated prognosis, and frequently the more-or-less broad range of prospects, needed to include the chances of survival and data on acute and long-term morbidities. However, in the interest of a having an informed basis for parental decision-making with a professional interdisciplinary team, this process needs to acknowledge the rights of the parents for a comprehensive presentation of the expected quality of life of their child, the potential consequences for family life, and the couple’s own relationship. Besides expert advice, professional psychological and familial support is needed as a basis for a well-founded decision regarding the best treatment options for the child. It needs to be acknowledged by the professional team that the parental estimate of a “good outcome” or quality of life does not necessarily reflect the attitudes and recommendations of the professional team. Building a mutually trusting relationship is essential to avoid decision conflicts.

Improving survival in patients with trisomy 18

The effects of medical and surgical interventions on the survival of patients with trisomy 18 have been reported, leading to changes in perinatal management and decision-making. However, few studies have fully reported the recent changes in survival and treatment of trisomy 18. We examined how treatment and survival of patients with trisomy 18 have changed over a decade in a Japanese pediatric tertiary referral center. This retrospective cohort study included patients with trisomy 18 who were admitted within the first 7 days of life at the Hyogo Prefectural Kobe Children's Hospital between 2008 and 2017. The patients were divided into early period (EP) and late period (LP) groups based on the birth year of 2008-2012 and 2013-2017, respectively. Changes in treatment and survival rates were compared between the two groups. A total of 56 patients were studied (29 in the EP group and 27 in the LP group). One-year survival rates were 34.5% and 59.3% in the EP and LP groups, respectively. The survival to discharge rate significantly increased from 27.6% in the EP group to 81.5% in the LP group (p < 0.001). The proportion of patients receiving surgery, especially for congenital heart defects, significantly increased from 59% in the EP group to 96% in the LP group (p = 0.001). In our single-center study, survival and survival to discharge were significantly improved in patients with trisomy 18, probably because of increased rate of surgical interventions. These findings may facilitate better decision-making by patients' families and healthcare providers.

Trisomy 18 Trends over the Last 20 Years

OBJECTIVE

To evaluate the trends in hospitalizations for children with trisomy 18 over time and to determine the rate of invasive procedures on these children, using a large inpatient database.

STUDY DESIGN

A retrospective analysis using the Kids' Inpatient Database from 1997 to 2016 was performed for trisomy 18. We evaluated survival to discharge as well as the presence of pulmonary, skeletal, neurologic, gastrointestinal, renal, and hematologic/bleeding problems. We also searched for the following interventions, if performed: gastrostomy tube placement, tracheostomy, or cardiac procedure.

RESULTS

Over this period 10 151 admissions occurred in children with a diagnosis of trisomy 18. Between 1997 and 2016, the number of children admitted annually with trisomy 18 increased 74% from 1036 to 1798. The proportion of patients born prematurely remained stable at 14%-16% throughout the study. Gastrostomy tube placement increased 12-fold during the study period, tracheostomy increased 11-fold, and cardiac intervention increased 5-fold. The overall mortality rate decreased in those with trisomy 18 from 32% in 1997 to 21% in 2016.

CONCLUSIONS

We highlight a decreased inpatient mortality rate during the study period. The number of children undergoing interventions such as gastrostomy tube and tracheostomy increased, as did the number of children undergoing cardiac intervention. Although the number of procedures has increased with the mortality rate decreasing, it is unclear at present whether the 2 are related.

Management of Children with the Trisomy 18 and Trisomy 13 Syndromes: Is there a Shift in the Paradigm of Care?

OBJECTIVE

The conventional view toward the management of infants with the trisomy 18 and trisomy 13 syndromes has been to recommend pure comfort care and the avoidance of technological interventions. This commentary aims to address the recently raised question about whether there has been a shift in the paradigm of the management of infants with the two conditions.

STUDY DESIGN

The study design includes narrative review of the literature.

RESULTS

A body of opinion pieces and evidence has emerged indicating that there has been a recent increase in the administration of interventions, including ventilatory support and surgery, in the management of children with these syndromes.

CONCLUSION

Based on the evidence in the literature, the author concludes that there has been a type of paradigm shift described by philosopher of science, Thomas Kuhn, in the treatment of infants with trisomy 18 and 13. More parents are being offered and choosing technological interventions, including cardiac surgery. Future investigation of the question whether intervention improves outcome, including the quality of life, is crucial in addressing the unanswered questions in this dialogue.

KEY POINTS

· The conventional approach to the treatment of trisomy 18 and 13 has been to avoid interventions.. · There is a growing body of evidence that this traditional view of management is changing.. · Future investigation of whether intervention improves outcome is crucial in addressing the unanswered questions..

Hirschsprung disease with Edward syndrome: A rare association: A case report

INTRODUCTION AND IMPORTANCE

Edward's syndrome (ES) occurs as a result of trisomy of chromosome 18 and is associated with multisystem congenital anomalies. The association of ES with various gastrointestinal malformations but Hirschsprung disease (HD) is well documented.

CASE PRESENTATION

A female infant on her 5th day of life presented with episodes of bilious vomiting along with abdominal distension and no passage of stool. The child had a small head and prominent occiput, low set abnormal ears, small jaw, upturned nose, widely spaced eyes, small neck with widely spaced nipples, clenched hands with overlapping fingers, flexed big toe, and prominent heels.

CLINICAL DISCUSSION

Edward syndrome is associated with multisystem congenital abnormalities of which gastrointestinal abnormalities make up the most part. The condition can be identified by fetal ultrasound screening. Surgical correction of associated congenital anomalies at different times along with lifelong supportive management is important.

CONCLUSIONS

Edward syndrome can present as Hirschsprung disease as a part of associated gastrointestinal Malformation. Often, early identification and termination of the pregnancy in antenatal life can reduce the suffering. Surgical correction of associated anomalies along with supportive care forms the cornerstone of management. However, the prognosis remains poor.

An Ethical Pathway to Quality of Life in Critically Ill Newborns

Advances in perinatology have permitted the survival of fragile neonates. Quality of life (QoL) has been considered a key element in medical decision-making. In this review we analyse the role of QoL regarding the decision of withholding or withdrawing of life-sustaining treatment (LST). The role of QoL is debated because of the conceptual difficulties it raises. The lack of consensus on its definition and the difficulties in measuring it objectively, mean that basing clinical decisions solely on QoL has some risks. To avoid a purely subjective assessment, the principle of totality, and the principle of therapeutic adequacy should be considered. In case of uncertain prognosis, some therapeutic persistence seems reasonable. If this does not benefit the clinical condition of the child, then it may be no longer appropriate to continue the LST in case of severe disabilities. QoL is essential in medical decision-making, but is insufficient as the only criterion.

To operate or not to operate? Assessing NSQIP surgical outcomes in trisomy 18 patients

BACKGROUND

Trisomy 18 is associated with a wide range of potentially fatal congenital conditions. Historically, clinical attitudes on treatment have been ambiguous, with palliative care as the standard of care. The aim of our study was to provide a descriptive analysis of surgical outcomes in patients with trisomy 18.

STUDY DESIGN

We identified patients with trisomy 18 aged 0-18 years using the NSQIP-Pediatric database from 2012 to 2017 and analyzed demographics, surgery types, and perioperative characteristics of patients with trisomy 18 patients undergoing surgical intervention. Additionally, a case-match analysis was performed to assess surgical outcome differences.

RESULTS

A total of 310 patients with trisomy 18 were identified. Thirty-one percent were >5 years of age and 73% were female. The most common surgical types were general surgery procedures (57.4%), followed by orthopedics (18.1%) and ENT (10.3%). Operations performed increased from 8% (2012) to 26% (2017), and only 23% of patients had previous cardiac surgery. Majority of patients had no prior history of malignancy (95%) and 5% had a tracheostomy placed. Discharge to home was achieved in 74% of patients, with a median total hospital length of stay of 5 days (IQR 17). Furthermore, 90% survived over 30 days from the operation. Thirty-two patients had readmissions and the most common reasons were dehydration, gastrostomy infection or malfunction. Surgical site infections occurred in <3% of patients. No differences in complications, length of stay, reoperations, and readmissions were identified by case-match analysis.

CONCLUSION

In this data set, patients with trisomy 18 undergoing noncardiac surgical procedures experience excellent surgical outcomes with minimal morbidity and low mortality. Most patients more than a year of age will experience similar outcomes to patients without trisomy 18.

TYPE OF STUDY

Treatment study (retrospective comparative study) LEVEL OF EVIDENCE: Level III.
