Impact of Care Burden on the Quality of Life in Families of Children with Solid-Organ Transplants

OBJECTIVES

This study aimed to investigate the effects of care burden on the quality of life of parents who have children who have undergone solid-organ transplant.

MATERIALS AND METHODS

The research was conducted as a descriptive correlational study. Researchers collected data through face-to-face interviews with parents of patients registered in the Solid Organ Transplantation and Pediatric Nephrology outpatient clinic of Akdeniz University Hospital. The data collection tools included a Descriptive Information Form, the SF-36 Quality of Life Scale, and the Zarit Caregiver Burden Scale. Data were analyzed using descriptive statistics, percentages, Pearson correlation analysis, t tests, analysis of variance, and the Kruskal-Wallis test.

RESULTS

Parents in the study had a mean age of 32.12 ± 5.42 years; 100% of the parent participants were mothers. Among children who received transplants, 55.8% were boys. Solid-organ transplant types included 86% with liver transplants and 6.9% with kidney transplants. The mean burden of care score of parents was 38.72 ± 7.12, and the mean quality of life score was 28.14 ± 1.49. A significant negative correlation was found between the care burden of parents and their quality of life.

CONCLUSIONS

Families of children with solid-organ transplants face a significant care burden, which negatively affects their quality of life. The burden extends beyond parents to siblings and the overall family dynamics. Health care providers should recognize and address this burden by implementing comprehensive support services tailored to the specific needs of these families. A multidisciplinary approach involving various professionals is necessary to provide effective support. Interventions such as respite care, support groups, counseling services, and educational programs can help alleviate the burden and improve the overall well-being of these families. Future research should aim to develop targeted interventions and explore the experiences of these families in more depth.

Surgical Management and Outcomes of Patients with Multifocal Hepatoblastoma

OBJECTIVE

To compare the outcomes of patients with multifocal hepatoblastoma (HB) treated at our institution with either orthotopic liver transplant (OLTx) or hepatic resection to determine outcomes and risk factors for recurrence.

BACKGROUND

Multifocality in HB has been shown to be a significant prognostic factor for recurrence and worse outcome. The surgical management of this type of disease is complex and primarily involves OLTx to avoid leaving behind microscopic foci of disease in the remnant liver.

METHODS

We performed a retrospective chart review on all patients <18 years of age with multifocal HB treated at our institution between 2000 and 2021. Patient demographics, operative procedure, post-operative course, pathological data, laboratory values, short- and long-term outcomes were analyzed.

RESULTS

A total of 41 patients were identified as having complete radiologic and pathologic inclusion criteria. Twenty-three (56.1%) underwent OLTx and 18 (43.9%) underwent partial hepatectomy. Median length of follow-up across all patients was 3.1 years (IQR 1.1-6.6 years). Cohorts were similar in rates of PRETEXT designation status identified on standardized imaging re-review (p = .22). Three-year overall survival (OS) estimate was 76.8% (95% CI: 60.0%-87.3%). There was no difference in rates of recurrence or overall survival in patients who underwent either resection or OLTx (p = .54 and p = .92 respectively). Older patients (>72 months), patients with a positive porta hepatis margin, and patients with associated tumor thrombus experienced worse recurrence rates and survival. Histopathology demonstrating pleomorphic features independently associated with worse rates of recurrence.

CONCLUSIONS

Through proper patient selection, multifocal HB was adequately treated with either partial hepatectomy or OLTx with comparable outcome results. HB with pleomorphic features, increased patient age at diagnosis, involved porta hepatis margin on pathology, and the presence of associated tumor thrombus may be associated with worse outcomes regardless of the local control surgery offered.

Overview of Physical, Neurocognitive, and Psychosocial Outcomes in Pediatric Intestinal Failure and Transplantation

PURPOSE OF REVIEW

Intestinal failure and transplantation may significantly impact physical, neurocognitive, and psychosocial development in pediatric patients. Currently, there is a paucity of literature on the effects of intestinal failure and transplantation on these aspects of development. This article will review the current literature and discuss the short and long-term impacts as well as interventions to improve clinical outcomes in children with intestinal failure or those undergoing transplantation.

RECENT FINDINGS

Psychological disorders, neurodevelopmental delay, and social maladaptation are frequently encountered in this patient population. While the main focus is often on medical management, equal emphasis should be placed on other aspects of development such as increasing social support and improving school performance. The transition to adulthood also presents many obstacles for patients and healthcare providers should anticipate challenges such as childbirth, employment, and raising a family. The pre-operative, perioperative, and post-operative periods all represent opportunities for medical intervention. Frequent monitoring of physical, psychosocial, and neurocognitive status helps to improve clinical outcomes and long-term quality of life. Future research should emphasize continued development of multidisciplinary programs and specialized services to help address the physical and psychosocial needs of children with intestinal failure as well as transplant recipients.

A text messaging intervention and quality of life in adolescents with solid organ transplants

BACKGROUND

Facilitating communication between adolescents and HCP outside of appointments may enhance patient experience and outcomes. The purpose of this study was to determine whether SMS enhances the healthcare experience, QoL, and medication adherence in adolescent SOT patients.

METHODS

This was a prospective observational study of an SMS platform (WelTel Inc) for SOT patients aged 12-19 years. QoL was assessed before and after using the PedsQL™ Transplant Module. Medication adherence was assessed with the frequency of therapeutic tacrolimus levels and variation based on control chart analysis. Patient experience and engagement was evaluated with surveys, response rate to messages, and number of clinical conversations (>2 messages).

RESULTS

Twenty-three patients were included (median age 15.7 years (IQR 13.6-17.1)). Median intervention duration was 13.5 months (range 4.0-16.7 months). There was a 68% response rate (742/1095) with 375 clinical conversations. The majority of patients reported the intervention provided a positive outlook on their health (17/23), was useful (18/23), and improved their connection to HCPs (17/23). Following the intervention, there was no significant difference in the median scaled QoL scores (pre-intervention: 81 (IQR 76.5-93.3), post-intervention: 78 (IQR 76-93); p = .37), mean percentage of therapeutic tacrolimus levels (pre-intervention: 52 ± 25%, post-intervention: 65 ± 17%; p = .07), or variation on control chart analysis of tacrolimus levels.

CONCLUSIONS

The WelTel messaging platform provided supplemental clinical care for a group of adolescent SOT patients that enhanced their healthcare experience. Patient QoL and adherence were unchanged following the intervention and remained at a high level.

Cell phone support to improve medication adherence among solid organ transplant recipients

For many adolescent and young adult solid organ transplant recipients, medication non-adherence is a mortal issue. This study investigated the feasibility, acceptability, and potential efficacy of a 12-week cell phone support intervention to improve immunosuppressant medication adherence. A small sample (N = 8) of non-adherent adolescent and young adult transplant recipients, aged 15-20.5 years, was enrolled. Cell phone support consisted of short calls each weekday including medication reminders, discussion of needs, problem-solving support, and promotion of clinic and community resources. Changes in adherence were measured by self-report and laboratory values, and intervention acceptability, adherence barriers, social support, depression, and substance use were assessed by self-report. Pre-post effect sizes showed medium-to-large improvements in adherence, lasting through a 12-week follow-up assessment. There were also small-to-medium changes in adherence barriers, social support, and depression. However, acceptability and feasibility were limited, due to a low rate of enrollment by eligible male participants. Cell phone support interventions may promote medication adherence among adolescents and young adults. Cell phone support warrants further investigation, including a randomized controlled trial to evaluate efficacy.

Adherence and the pediatric transplant patient

Adherence is proving to be the Achilles heel of pediatric transplantation. Through a careful literature review on adherence in pediatric solid-organ transplantation from 2007 to 2017, this chapter reports on the incidence, measuring tools, and consequences of poor adherence. We detail adherence determinants and interventions proposed to foster it. While adherence is a major problem in the adolescent age, it clearly is not limited to this age group. Importantly, it is not one to start tackling at that time or when it becomes apparent. Rather, fostering adherence should be built throughout the continuum of the transplant journey, starting in the pretransplantation phase. Adherence is clearly a fluid state, necessitating frequent reassessments and enforcement. Adherence in addition shares similar determinants with quality of life. The severe consequences in the case of poor adherence mandate that the transplant community prioritize it as the next frontier in transplantation. Good adherence is what will pave the road to tolerance, cost-efficient transplantation, and optimized long-term outcomes.

Pediatric transplantation and tolerance: past, present, and future

Solid organ transplantation is the treatment of choice in children with end-stage organ failure. With improving methods of transplant surgery and post-transplant care, transplantation is more frequently performed worldwide. However, lifelong and non-specific suppression of the recipient's immune system is a cause of significant morbidity in children, including infection, diabetes, and cancer. There is a great need to develop IS minimization/withdrawal and tolerance induction approaches.

Clinical transplantation and tolerance: are we there yet?

Organ transplantation is not only considered as the last resort therapy but also as the treatment of choice for many patients with end-stage organ damage. Recipient-mediated acute or chronic immune response is the main challenge after transplant surgery. Nonspecific suppression of host immune system is currently the only method used to prevent organ rejection. Lifelong immunosuppression will cause significant side effects such as infections, malignancies, chronic kidney disease, hypertension and diabetes. This is more relevant in children who have a longer life expectancy so may receive longer period of immunosuppressive medications. Efforts to minimize or complete withdrawal of immunosuppression would improve the quality of life and long-term outcome of pediatric transplant recipients.

Impact of medication non-adherence on survival after pediatric heart transplantation in the U.S.A

BACKGROUND

Medication non-adherence (NA) can result in life-threatening illness in children after solid-organ transplantation. Little is known about the incidence, risk factors and outcomes of NA in large numbers of pediatric heart transplant (HT) recipients.

METHODS

Organ Procurement Transplant Network (OPTN) data were used to identify all children <18 years of age in the U.S.A. who underwent HT from October 1999 to January 2007. Cox proportional hazards analysis was used to identify risk factors for NA and the effect on graft survival.

RESULTS

Of 2,070 pediatric heart transplants performed the median age at transplant was 6 years (interquartile range [IQR] 0 to 13 years); 40% had congenital heart disease (CHD), 7% were re-transplants, 42% were non-white and 43% had Medicaid insurance. Overall, 186 (9%) children had a report of NA at a median age of 15 years with more than two-thirds of NA episodes occurring after 12 years of age. Factors independently associated with NA were: adolescent age at transplant (hazard ratio [HR] 7.0, 95% confidence interval [CI] 4.1 to 12, compared with infants); black race (HR 2.3, 95% CI 1.7 to 3.3, compared with white); Medicaid insurance (HR 2.0, 95% CI 1.5 to 2.7, compared with non-Medicaid insurance); and ventilator or ventricular assist device (VAD) support at transplant. The risk of mortality conditional upon report of NA was 26% at 1 year and 33% at 2 years.

CONCLUSIONS

Medication NA is an important problem in pediatric HT recipients and is associated with high mortality. Adolescent age, black race, Medicaid insurance and invasive hemodynamic support at transplant were associated with NA, whereas time on the wait list and gender were not. Targeted interventions among at-risk populations may be warranted.

Long-term outcomes of living donor kidney transplants in pediatric recipients following laparoscopic vs. open donor nephrectomy

We compared long-term outcomes of LDKT in pediatric recipients following either laparoscopic (LDN) or ODN. In our retrospective single-center study, we compared 38 pediatric LDKT recipients of a laparoscopically procured kidney with a historic ODN group comprising 17 pediatric recipients. In our center, the first pure laparoscopic non-hand-assisted LDN for a pediatric LDKT recipient was performed in June 2001. Demographic data of donors and recipients were comparable between groups. Mean follow-up was 64 months in the LDN group and 137 months in the ODN group. Patient survival was comparable between groups. Graft survival at one and five yr was 97% (LDN) vs. 94% (ODN) and 91% (LDN) vs. 88% (ODN; p = n.s.), respectively. Serum creatinine at one and five yr was 1.16 ± 0.47 mg/dL (LDN) vs. 1.02 ± 0.38 mg/dL (ODN) and 1.38 ± 0.5 mg/dL (LDN) vs. 1.20 ± 0.41 mg/dL (ODN), respectively. The type and frequency of surgical complications did not differ between groups. DGF and acute rejection rates were similar between groups. In the ODN group, a higher proportion of right donor kidneys was used. In the ODN group, all kidneys had singular arteries, whereas in the LDN group five kidneys had multiple arteries. Arterial multiplicity was associated with a higher incidence of DGF. In our experience, LDN does not compromise long-term graft outcomes in pediatric LDKT recipients. Arterial multiplicity of the donor kidney may be a risk factor for impaired early graft function in the pediatric population.
