Psychosocial implications during adolescence for infant heart transplant recipients

Neurodevelopmental Outcomes for Individuals With Congenital Heart Disease: Updates in Neuroprotection, Risk-Stratification, Evaluation, and Management: A Scientific Statement From the American Heart Association

Over the past decade, new research has advanced scientific knowledge of neurodevelopmental trajectories, factors that increase neurodevelopmental risk, and neuroprotective strategies for individuals with congenital heart disease. In addition, best practices for evaluation and management of developmental delays and disorders in this high-risk patient population have been formulated based on literature review and expert consensus. This American Heart Association scientific statement serves as an update to the 2012 statement on the evaluation and management of neurodevelopmental outcomes in children with congenital heart disease. It includes revised risk categories for developmental delay or disorder and an updated list of factors that increase neurodevelopmental risk in individuals with congenital heart disease according to current evidence, including genetic predisposition, fetal and perinatal factors, surgical and perioperative factors, socioeconomic disadvantage, and parental psychological distress. It also includes an updated algorithm for referral, evaluation, and management of individuals at high risk. Risk stratification of individuals with congenital heart disease with the updated categories and risk factors will identify a large and growing population of survivors at high risk for developmental delay or disorder and associated impacts across the life span. Critical next steps must include efforts to prevent and mitigate developmental delays and disorders. The goal of this scientific statement is to inform health care professionals caring for patients with congenital heart disease and other key stakeholders about the current state of knowledge of neurodevelopmental outcomes for individuals with congenital heart disease and best practices for neuroprotection, risk stratification, evaluation, and management.

Ethical and practical dilemmas in cardiac transplantation in infants: a literature review

The waiting time in infants for a cardiac transplant remains high, due to the scarcity of donors. Consequently, waiting list morbidity and mortality are higher than those in other age groups. Therefore, the decision to list a small infant for cardiac transplantation is seen as an ethical dilemma by most physicians. This review aims to describe outcomes, limitations, and ethical considerations in infant heart transplantation. We used Medline and Embase as data sources. We searched for publications on infant (< 1 year) heart transplantation, bridge-to-transplant and long-term outcomes, and waiting list characteristics from January 2009 to March 2021. Outcome after cardiac transplant in infants is better than that in older children (1-year survival 88%), and complications are less frequent (25% CAV, 10% PTLD). The bridge-to-transplant period in infants is associated with increased mortality (32%) and decreased transplantation rate (43%). This is mainly due to MCS complications or the limited MCS options (with 51% mortality in infancy). Outcomes are worse for infants with CHD or in need of ECMO-support.Conclusion: Infants listed for cardiac transplantation have a high morbidity and mortality, especially in the period between diagnosis and transplantation. For those who receive cardiac transplant, the outlook is encouraging. Unfortunately, despite growing experience in VAD, mortality in children < 10 kg and children with CHD remains high. After transplantation, patients carry a psychological burden and there is a probability of re-transplantation later in life, with decreased outcomes compared to primary transplantation. These considerations are seen as an important ethical dilemma in many centers, when considering cardiac transplantation in infants (< 1 year). What is Known: • For infants, waitlist mortality remains high. In the pediatric population, MCS reduces the waiting list mortality. What is New: • Outcomes after infant cardiac transplantation are better than other age groups; however, MCS options remain limited, with persistently high waiting list mortality. • Future developments in MCS and alternative options to reduce waiting list mortality such as ABO-incompatible transplantation and pulmonary artery banding are encouraging and will improve ethical decision-making when an infant is in need of a cardiac transplant.

Early school-age cognitive performance post-pediatric heart transplantation

BACKGROUND

As survival in pediatric heart transplantation (HTx) has improved due to medical advances, the analysis of long-term outcomes impacting quality of life such as cognition and development becomes increasingly important. Neuropsychological assessments provide a comprehensive understanding of individual needs, allowing for the development of tailored recommendations and interventions.

METHODS

Routine neuropsychological assessment was completed between 5 and 7 years of age in this cohort of pediatric HTx recipients at our center (Jan 2014-Oct 2018), including tests of general intellect (WPPSI-IV, WISC-V), academics (WIAT-II/III), perceptual-motor abilities (Beery VMI), and memory (CMS). Relevant medical variables were collected.

RESULTS

Among 25 children, the median age at testing was 6.7 (IQR:5.8-7.4) years, with a median time since HTx of 5.2 (IQR:4.8-6.8) years. Medical diagnoses included congenital heart disease (CHD; 56%) and cardiomyopathy (44%). Cognitive functioning across the intellectual, academic, and perceptual-motor domains fell within the low-average range, while memory abilities fell within the average range. DSM-5 clinical diagnoses were provided for 14 (56%) children: Intellectual Disability-Mild (20%), Learning Disability (20%), Language Disorder (8%), and Attention-Deficit/Hyperactivity Disorder (12%). The presence of neurological issues and/or CHD predicted poorer performance on various neuropsychological domains.

CONCLUSIONS

Over 50% of this cohort of pediatric heart transplant recipients seen for routine post-HTx neuropsychological assessment received a clinical psychological diagnosis, notably higher than rates in the general population. This population requires monitoring to ensure that high risk children are identified and successfully supported in school and their community.

Health-related quality of life after pediatric heart transplantation in early childhood

BACKGROUND

There is limited information about HRQL after pediatric heart transplantation at a young age.

METHODS

Prospective follow-up study of children who received a heart transplant at age ≤4 years. HRQL was assessed using the PedsQL^TM 4.0 at age 4.5 years. This cohort was compared with healthy children, children with CHD, and with chronic conditions. Peri-operative factors associated with HRQL were also explored.

RESULTS

Of 66 eligible patients, 15 (23%) died prior to the HRQL assessment and 2 (3%) were lost to follow-up, leaving 49 patients. Indication for transplantation was CHD in 27 (55%) and CMP in 22 (45%). Median age (IQR) at transplant was 9 (5-31) months. HRQL was significantly lower in transplanted children compared to population norms (65.3 vs 87.3, P < .0001), children with chronic conditions (65.3 vs 76.1, P = .001), and children with CHD (65.3 vs 81.1, P < .0001). Transplanted children with CHD had lower HRQL than those with a prior diagnosis of CMP (59.5 vs 72.5, P-value = .020). Higher creatinine pretransplant and higher lactate post-operatively were associated with lower HRQL.

CONCLUSION

Children after heart transplant had significantly lower HRQL, as reported by their parents, than the normative population, children with chronic conditions, and children with CHD.

Executive Functioning in Pediatric Solid Organ Transplant Recipients: A Meta-analytic Review

BACKGROUND

Examining executive functioning (EF) posttransplant has become increasingly prevalent, as EF deficits are associated with poor disease-related outcomes and psychosocial functioning. The purpose of the current meta-analysis was to compare overall and domain-specific EF between healthy youth and those with a kidney, heart, or liver transplant, and identify moderating variables related to EF differences between these 2 groups.

METHODS

A literature search of PsycINFO, Pubmed, and Medline was conducted for eligible articles published until January 2019. Twenty studies met eligibility criteria and were included in the present meta-analysis.

RESULTS

Results from the random-effects model indicated a significant standardized mean difference in overall EF skills with transplant recipients demonstrating worse EF (g = 0.40; 95% confidence interval [CI], 0.29-0.50) than healthy youth. Specifically, transplanted youth had worse working memory (g = 0.33; 95% CI, 0.01-0.66), processing speed (g = 0.41; 95% CI, 0.19-0.62), attentional control (g = 0.53; 95% CI, 0.33-0.73), and metacognitive skills (g = 0.36; 95% CI, 0.18-0.54). Assessment type and time since transplantation were not significant moderators.

CONCLUSIONS

Pediatric solid organ transplant recipients demonstrate worse overall EF skills and deficits in working memory, processing speed, attentional control, and metacognitive skills. Many children who have undergone solid organ transplantation will require additional support in medical and academic settings because of deficits in various EF domains.

A comparison of quality of life and psychological distress in heart transplantation patients at adult and pediatric ages

BACKGROUND

The aim of the current study was to evaluate and compare the quality of life (QOL) and psychological status of adult patients who underwent heart transplant (HTx) at pediatric or adult ages.

METHODS

The population consisted of two groups: patients who received HTx after 18 years old and pediatrics who received HTx between the age of 1 and 18 years. At the time of the study, all patients were over 18 years old. QOL data were collected from patients using 36-item Short-Form Health Survey (SF-36) and psychological distress by the Symptom checklist 90-revised questionnaire (SCL-90-R).

RESULTS

A total of 232 HTx patients were evaluated; 217 were transplanted at an adult age and 15 at a pediatric one. QOL improved significantly in pediatrics patients in the general health perceptions subscale and physical pain subscale than adult patients. The Global Index of the psychological distress did not differ in the two groups, but the pediatric patients registered statistically significant higher scores on the interpersonal sensitivity symptom subscale (adult group 36 ± 0.42 vs pediatric group 81 ± 0.79), the hostility subscale (adult group m 39 ± 0.44 vs pediatric group 73 ± 0.76) and the paranoid ideation subscale (adult group 46 ± 0.46 vs pediatric group 96 ± 1.02).

CONCLUSION

The pediatric heart recipients showed better quality of life, but they show marked sensitivity, hostility and paranoid ideation which increases the risk of mental distress and therefore their adherence to medical treatment.

Clinically Significant Psychological and Emotional Distress in 32% of Adolescent Idiopathic Scoliosis Patients

STUDY DESIGN

Prospective study of 92 patients.

OBJECTIVES

To determine if the incidence of clinically significant psychological and emotional distress in adolescent idiopathic scoliosis (AIS) patients is higher than the general population and if this correlates with deformity severity.

SUMMARY OF BACKGROUND DATA

Adolescents with scoliosis may exhibit a less positive outlook on life, suffer from lower self-esteem, and have more difficulty connecting with peers; however, there is conflicting evidence whether different stages of treatment prompt different psychological problems and the long-term psychological effect of scoliosis.

METHODS

Patients aged 12-21 years with a diagnosis of AIS were included. The Behavioral Assessment System for Children, Second Edition (BASC-2), is a validated 139-item survey normed on more than 1 million children in the United States. It can detect clinical and subclinical levels of psychosocial problems in five domains: school problems, internalizing problems, inattention/hyperactivity, emotional symptoms index, and personal adjustment. The BASC-2 self-report form was completed by 92 adolescents with AIS (mean age = 14 years; range 12-18) and a parent. BASC-2 scale scores were compared to validated age-matched normative data. Comparisons were made between those undergoing surgery (n = 31), bracing (n = 31), or observation (n = 30) at the start of treatment.

RESULTS

32% (29/92) of patients scored in the clinically significant range in at least one of the subscales. There were no clinically significant emotional or behavioral differences when stratified by treatment type (p = .560), Cobb angle (0.630), or age (0.313). Twenty-one percent (19/92) of parent responses deemed their kids as having clinically significant emotional or behavioral differences. In only 34% (10/29) of the cases did children and parent concurrently report clinically significant psychological difficulties, such that 66% of parents were unaware that their child has clinically significant emotional or behavioral problems.

CONCLUSIONS

AIS patients undergoing observation, bracing, and surgery are all at risk for clinically significant psychological symptoms.

LEVEL OF EVIDENCE

Level II.

Pregnancy after heart transplantation: a well-thought-out decision? The Quebec provincial experience - a multi-centre cohort study

Despite reports of successful pregnancies in heart transplant (HTx) recipients, many centers recommend their patients against maternity. We reviewed our provincial experience of pregnancy in HTx recipients by performing charts review of all known gestations following HTx in the province of Quebec (Canada), stratified between planned and unplanned pregnancies. Long-term survival was compared to HTx recipient women of childbearing age who did not become pregnant. Eighteen pregnancies, 56% unplanned, occurred in eight patients, 10.1 (2.6-27.0) years after HTx. Immunosuppression was CNI-based, with a mean dose increase of 48.3% (tacrolimus) and 26.5% (cyclosporine), without rejection. Cardiometabolic complications were high compared to the general Canadian population, including preeclampsia (15.4% vs. 5.5%), hypertension (38.5% vs. 4.6%), and diabetes (15.4% vs. 5.6%). Mean gestational age was 35.1 (23.4-39.6) weeks (72.2% live births; 53.8% prematurity). Mean birthweight was 2418 (660-3612) g. Serum creatinine increased during pregnancy, becoming significant after delivery (P = 0.0239), and returning to preconception level in all but three patients within a year. After 4.6 (1.2-17.2) years of follow-up, two rejection episodes occurred in one patient. Long-term mortality was similar to overall HTx women (Kaplan-Meier; P = 0.8071). Pregnancy in HTx carries high cardiometabolic complications and decreased kidney function, but is feasible with acceptable outcomes and no impact on mother's survival.

Post-transplant adjustment--the later years

As survival rates for pediatric solid organ transplantation have continued to improve, researchers and healthcare providers have increasingly focused on understanding and enhancing the HRQOL and psychosocial functioning of their patients. This manuscript reviews the psychosocial functioning of pediatric transplant recipients during the "later years," defined as more than three yr post-transplant, and focuses on the day-to-day impact of living with a transplant after the immediate period of adjustment and early years after surgery. Key topics reviewed include HRQOL, cognitive functioning, impact on the family, regimen adherence, and transition of responsibility for self-management tasks. Overall, pediatric transplant recipients evidence impairment in HRQOL, neuropsychological outcomes, and family functioning as compared to non-transplant recipients. However, the degree of impairment is influenced by a variety of factors including, disease severity, age, solid organ type, and study methodologies. Studies are limited by small samples, cross-sectional design, and the lack of universal assessment battery to allow for comparisons across solid organ populations. Areas for future research are discussed.

Child and family adjustment following pediatric solid organ transplantation: factors to consider during the early years post-transplant

Adjusting to life after transplant can be challenging to pediatric solid organ transplant recipients and their families. In this review, we discuss a number of important factors to consider during the first 2-3 yr after transplant (defined as the "early years"), including transitioning from hospital to home, returning to physical activity, feeding and nutrition, school reentry, potential cognitive effects of transplant, family functioning, and QOL. We highlight steps that providers can take to optimize child and family adjustment during this period.
