ATRT-02. Neuropsychological function in infant atypical teratoid/rhabdoid tumor versus low-grade glioma survivors reflects tumor malignancy and multimodal treatment [Abstract]

BACKGROUND: Therapy of infants with brain tumors predisposes these patients to increased risks for cognitive sequelae, especially following radiotherapy. Neuropsychological outcome gains importance for those 40-60% of patients with an atypical teratoid/rhabdoid tumor (ATRT) who survive beyond 2 years. Still, reports on cognitive late-effects in children with ATRT are scarce compared to other pediatric brain tumor groups. We analyzed neuropsychological outcome for long-term ATRT-survivors registered in EU-RHAB and infant low-grade glioma (LGG) survivors from the SIOP-LGG 2004-study and LGG-registry. PATIENTS+METHODS: Age at diagnosis of both cohorts was 0-36 months. ATRT-patients (n=13) treated with up to 54Gy radiotherapy (median age 22 months (±7.1)) were evaluated with the “ATRT-Neuropsychology” tool based on SIOPE-BTG QoS-Group recommendations at median 6.8 years (±2.8) after diagnosis. LGG-patients (n=15) treated without radiotherapy (4/15 with chemotherapy) were analyzed with the German “Neuropsychological-Basic-Diagnostic” tool 5.2 years (±0.6) post-diagnosis. RESULTS: The ATRT- vs. LGG-cohorts were comparable for median age at diagnosis, sex-ratio and tumor-localization, though they differed slightly in median age at assessment (9.5/7.2 years (±2.5/1.1)). Results of age-appropriate tests showed increased impairments for ATRT-patients in fluid intelligence (FI) (p=.006, d=1.214) and in visual-spatial processing (VSP) (p<.001, d=2.233) compared to LGG-patients. The median for neuropsychological test results of ATRT-patients spanned from considerably below the normal to the lower normal range (median=65-90), while results of LGG-patients were mostly in the lower normal range (median=83-103). Results for psychomotor speed abilities (PMS) were distinctly below the norm for both patient groups (p=.002-.007). CONCLUSION: Infant ATRT- and LGG-patients develop significant impairments in PMS abilities following multimodal treatment. Long-term survivors of ATRT suffer from additional FI and VSP deficits. Our data suggest that high malignancy requiring multimodal treatment determines the inferior cognitive outcome for the ATRT-cohort. Long-term neuropsychological monitoring (and treatment options) should be implemented as standard of care in ATRT- and LGG-trials

Barriers to the Successful Health Care Transition of Patients with Kidney Disease: A Mixed-Methods Study on the Perspectives of Adult Nephrologists

The transition from paediatric to adult-based health care is a challenging period bearing a high risk of medication nonadherence and transplant loss in adolescents and young adults after kidney transplantation. Successful transition asks for the cooperation of many, not least the adult physicians. Yet little is known about their thoughts and attitudes on the transition. We conducted a cross-sectional mixed-methods study, inviting all nephrologists registered with the German Society of Nephrology. A total of 119/1984 nephrologists answered an online survey, and 9 nephrologists participated in expert interviews on transition experiences and perceived barriers. Interviews were thematically analysed. Based on the results, 30 key statements were listed and returned to participants for a ranking of their relevance. The main themes extracted are (1) available resources, (2) patient-related factors, (3) qualification and (4) preparation of and cooperation with the paediatric setting. In conclusion, it became evident that successful transition faces multiple obstacles. At the least, it asks for time, staff, and money. Rigid structures in health care leave little room for addressing the specific needs of this small group of patients. Transition becomes a topic one wants to and is able to afford

Do We Need Palliative Care in Pediatric Nephrology? Patients’ and Caregivers’ Disease Experience

Chronic life-limiting illnesses such as chronic kidney disease (CKD) require integral support to the families concerned in addition to medical care. Palliative care is an option to facilitate families to address future concerns, such as procedures for acute life-threatening complications, or to relieve physical and psychosocial suffering. The exact needs of patients or parents have not yet been investigated. To assess needs in supportive palliative care, we conducted a monocentric qualitative interview study. We included patients 14 to 24 years old as well as parents of younger children (below 14 years) with CKD ≥ stage 3. In total, fifteen interviews were conducted. Data were analyzed with a deductive and descriptive approach using qualitative content analysis as described by Mayring. Sociodemographic data and basic information of disease were collected using questionnaires. In contrast to caregivers, adolescents and young adults do not express worries about their own mortality or reduced life expectancy. Rather, they report about their limitations to everyday life associated with the disease, especially in the areas of school and work. They wish to live a normal life. Caregivers are concerned about the future and the disease trajectory. They also describe difficulties in balancing the management of the disease with other responsibilities such as work and healthy siblings’ needs. Patients and caregivers appear to need a chance to talk about their everyday struggles and disease-related fears and concerns. Talking about their concerns and needs may help deal with their emotions and facilitate acceptance of their situation characterized by a life-limiting disease. Our study confirms the need for psychosocial support in pediatric nephrology to address the needs of the affected families. This can be offered by pediatric palliative care teams

Survey on Management of Transition and Transfer From Pediatric- to Adult-based Care in Pediatric Kidney Transplant Recipients in Europe

Background. Transition from pediatric- to adult-based healthcare is a challenging period and bears a high risk of medication nonadherence and transplant loss in adolescents and young adults after kidney transplantation. Yet, it remains unclear how the 2011 International Society of Nephrology (ISN)/International Pediatric Nephrology Association (IPNA) guidelines on transition are implemented in practice and which healthcare transition modalities are currently used in Europe. Methods. We performed an online survey inviting all members of the European Society of Paediatric Nephrology mailing list to participate. Adherence to ISN/IPNA guidelines was scored with a maximum of 15 points. Results. Thirty-nine centers from 24 countries accounting for approximately 2500 children after kidney transplantation participated in the survey. At 3 centers, patients remained under pediatric care for their whole life, and 5 centers did not use any transition procedure. From the remaining 31 centers, 82% confirmed the existence of at least 1 unwritten transition procedure. None of these centers used IT or social media for patient training in transition. Specialized transition clinics are held at 15 of 31 centers for the patients. Most patients were transferred at 16 to 21 years of age. Transfer age was subject to regulation at 20 of 36 centers. Median score of guidelines adherence was 10 (range, 0-14). The adherence score was significantly correlated with gross national income (r2 = 0.631, P < 0.0001). Conclusions. The 2011 ISN/IPNA guidelines on transition are implemented insufficiently in European pediatric nephrology centers. Therefore, further development is needed, and the use of information technology and social media should be promoted

Current management of transition of young people affected by rare renal conditions in the ERKNet

Transition in medical care is a high-risk period in adolescence and young adulthood. To date, data on transition policy, its application in practice, and transition procedures in patients with rare, hereditary kidney diseases in Europe is scarce. An online survey was developed and was distributed within the paediatric centres of the European Reference Network for Rare Kidney Diseases (ERKNet) aiming to assess the transition-relevant structures from the providers’ perspectives. Its items were based on the consensus statement on transition published by the International Society of Nephrology (ISN) and the International Paediatric Nephrology Association (IPNA) in 2011. Forty-six paediatric experts based at 28/32 ERKNet university hospitals participated. Annually, a median number of 14 patients (1–80) are transferred to adult based care. One centre continued to care for paediatric kidney transplant recipients throughout their entire lifespan. Choosing this option terminated the survey and no further data was obtained from this centre. 29/45 experts confirmed the application of an—at least unwritten—transition procedure (64%). Transition clinics are offered by 23 experts. Most physicians (40%) transfer patients at age 18–19, 10 experts at age <18. Most physicians transfer the patients to a university hospital and/or a community hospital. The transition guidelines have been implemented in ERKNet centres only partly and with huge heterogeneity. Implementation of transition tools and structures within ERKNet could improve health of children with hereditary kidney diseases. Adherence of experts to the transition-guidelines was significantly correlated with gross national income of their countries
