Parenting a Child with Phenylketonuria (PKU): an Interpretative Phenomenological Analysis (IPA) of the Experience of Parents

Psychosocial Challenges Facing Young People With Inherited Metabolic Disorders and Their Parents: A Systematic Review

Recent advancements in new-born screening have reduced the risk of life-threatening complications associated with inherited metabolic disorders. However, the risk of negative psychosocial effects on families persists. The aim of the present study was to systematically review the literature concerning the psychosocial challenges experienced by young people with metabolic conditions and their families, to inform the development of supports that meet the needs of those linked with metabolic services. The electronic databases MEDLINE, CINAHL, PsychInfo, and Psychology and Behavioural Sciences Collection were searched for studies examining psychosocial challenges reported by families with inherited metabolic conditions, over the last two decades. Five-thousand sixty-seven articles were screened for relevance. Twenty-nine studies met the inclusion criteria. Study quality and reliability were independently assessed by two reviewers. Results highlighted the myriad of physical, social, psychological and practical challenges experienced by young people with metabolic conditions and their families. These challenges included social isolation, burden of care, and learning and emotional difficulties. Findings reiterate the importance of developing peer support groups and delivering psychoeducation to families, as well as the central role psychology and social work should play in metabolic MDTs, to improve families' experiences and outcomes.

What is known about patients' quality of life with Phenylketonuria and their caregivers? A scoping review

BACKGROUND

Phenylketonuria (PKU) is a rare genetic disorder characterized by a deficiency in the metabolism of the essential amino acid phenylalanine, which has a neurotoxic effect at high concentrations. The available treatment for PKU involves limiting the intake of phenylalanine through a restrictive diet. Strict adherence to treatment is essential for a child's proper development. Owing to their rare and chronic condition, PKU patients and their caregivers need to address many specific challenges, which can affect their quality of life (QoL).

PURPOSE

This review aimed to identify, characterize, map, and summarize existing knowledge about the quality of life of PKU patients and their primary caregivers.

METHODS

A scoping review was conducted following the PRISMA-ScR guidelines. The PubMed, PsycINFO, EMBASE, Scopus, CINAHL, and BVS databases were searched, and articles published between January 2000 and February 2023 were included.

RESULTS

The search resulted in 3249 articles, 29 of which were selected for analysis. Most studies were cross-sectional, and the highest concentration of publications ranged between 2011 and 2021. Generic self-report questionnaires were the tools most commonly used to assess patients' and their caregivers' QoL. A significant negative impact on QoL was found in most studies with pediatric patients and caregivers. High current and lifetime blood Phe levels were associated with worse QoL in several domains, and higher tolerance of ingested phenylalanine was associated with a lower impact on QoL. Among caregivers, psychosocial variables such as stress, anxiety, depression, and child behavior problems were associated with poorer QoL. Higher perceived social and emotional support was a protective factor of QoL in caregivers.

CONCLUSION

Patients of pediatric age and their caregivers, younger caregivers, and female patients and caregivers seem to be especially vulnerable to QoL impairments. The social and emotional dimensions were the most affected. These results emphasize the importance of combining generic and disease-specific assessment tools to achieve a comprehensive assessment. Despite the growing interest in this topic, the longitudinal literature is limited, and there is a lack of interventional studies on this population. Future interventions addressing diet management and providing psychosocial support may benefit the QoL of the PKU population.

Benefits and harms of antenatal and newborn screening programmes in health economic assessments: the VALENTIA systematic review and qualitative investigation

Background

Health economic assessments are used to determine whether the resources needed to generate net benefit from an antenatal or newborn screening programme, driven by multiple benefits and harms, are justifiable. It is not known what benefits and harms have been adopted by economic evaluations assessing these programmes and whether they omit benefits and harms considered important to relevant stakeholders.

Objectives

(1) To identify the benefits and harms adopted by health economic assessments in this area, and to assess how they have been measured and valued; (2) to identify attributes or relevance to stakeholders that ought to be considered in future economic assessments; and (3) to make recommendations about the benefits and harms that should be considered by these studies.

Design

Mixed methods combining systematic review and qualitative work.

Systematic review methods

We searched the published and grey literature from January 2000 to January 2021 using all major electronic databases. Economic evaluations of an antenatal or newborn screening programme in one or more Organisation for Economic Co-operation and Development countries were considered eligible. Reporting quality was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. We identified benefits and harms using an integrative descriptive analysis and constructed a thematic framework.

Qualitative methods

We conducted a meta-ethnography of the existing literature on newborn screening experiences, a secondary analysis of existing individual interviews related to antenatal or newborn screening or living with screened-for conditions, and a thematic analysis of primary data collected with stakeholders about their experiences with screening.

Results

The literature searches identified 52,244 articles and reports, and 336 unique studies were included. Thematic framework resulted in seven themes: (1) diagnosis of screened for condition, (2) life-years and health status adjustments, (3) treatment, (4) long-term costs, (5) overdiagnosis, (6) pregnancy loss and (7) spillover effects on family members. Diagnosis of screened-for condition (115, 47.5%), life-years and health status adjustments (90, 37.2%) and treatment (88, 36.4%) accounted for most of the benefits and harms evaluating antenatal screening. The same themes accounted for most of the benefits and harms included in studies assessing newborn screening. Long-term costs, overdiagnosis and spillover effects tended to be ignored. The wide-reaching family implications of screening were considered important to stakeholders. We observed good overlap between the thematic framework and the qualitative evidence.

Limitations

Dual data extraction within the systematic literature review was not feasible due to the large number of studies included. It was difficult to recruit healthcare professionals in the stakeholder's interviews.

Conclusions

There is no consistency in the selection of benefits and harms used in health economic assessments in this area, suggesting that additional methods guidance is needed. Our proposed thematic framework can be used to guide the development of future health economic assessments evaluating antenatal and newborn screening programmes.

Caregiving experiences of caregivers of children with rare diseases: A qualitative meta-synthesis

PROBLEM

Most rare diseases occur in childhood and are difficult to diagnose and treat. The caregivers are faced with the challenge of providing care to the children afflicted with these rare diseases, resulting in a significant burden of care and an altered family dynamic.

ELIGIBILITY CRITERIA

A meta-synthesis review was conducted to explore the caregivers' experience of children with rare diseases using eight electronic databases PubMed, Web of Science, the Cochrane Library, EMBASE, VIP database, Wan Fang, Chinese BioMedical Literature Database, and China National Knowledge Infrastructure from each database's inception to October 5, 2023.

SAMPLE

4207 records were identified and 20 eligible studies were included.

RESULTS

Three themes emerged: (1) Life is changed by "rare"; (2) many unmet needs; (3) Strive to adapt and grow.

CONCLUSIONS

Caregivers of children with rare diseases are full of stress and challenges in the process of caring for them, and their lives have changed greatly due to "rare". Appropriate measures need to be taken to reduce the burden on caregivers.

IMPLICATIONS

According to the findings, both the medical and health systems, as well as society, should pay attention to the care load and unmet requirements of carers of children with rare diseases, and offer them with practical supportive services. Finally, it can improve the quality of life for caregivers and families of children with rare diseases, as well as stimulate the development of rare diseases.

Stress, coping, and positive aspects of caregiving among caregivers of children with rare disease

OBJECTIVE

Caregivers of children with rare diseases often consider caregiving to be a rewarding experience, despite high levels of burden. The present study examined associations between caregiver stress and positive aspects of caregiving (PAC); investigated associations between interpersonal coping strategies and PAC; and determined whether coping strategies moderated associations between stressors and PAC.

DESIGN

Survey data came from a study on caregivers across different caregiving conditions, including caregivers of children diagnosed with inherited metabolic conditions (n = 167), undiagnosed diseases (n = 23), and caregivers of typically-developing children (n = 74).

MAIN OUTCOME MEASURES

Positive Aspects of Caregiving (PAC) scale.

RESULTS

Results from generalized linear models indicated that perceived burden was not associated with PAC. Venting was negatively associated with PAC (b= -0.09, p=.03), whereas emotional support was associated with increased PAC for caregivers of children with undiagnosed conditions (b = 0.15, p=.02). Care needs were associated with greater PAC among caregivers engaged in high levels of emotional support coping (b = 0.10, p=.01) and venting (b = 0.09, p=.03).

CONCLUSION

These findings illuminate important differences in PAC based on the caregiving condition, and aspects of the caregiver stress process model that might be universal to caregivers. Results inform stress process theory and highlight the potential of support-based interventions for promoting PAC.

Becoming a Rare Disease Parent: An Interpretative Phenomenological Analysis of Parent-Caregivers' Postpartum Experiences

Rare diseases constitute a group of conditions that are individually rare, but in aggregate impact between 3 and 6% of the world population. Many of these conditions present during infancy and involve substantial caregiving responsibilities, often assessed via quantitative measurements. However, few qualitative analyses examine lived experiences of parent-caregivers during the early period of their child's life. The purpose of this study was to examine the meaning that rare disease parent-caregivers apply to the postpartum year using data collected from a semi-structured interview exploring significant experiences over the course of their affected child's life. We utilized an interpretative phenomenological analysis (IPA) approach to analyze 22 interview transcripts from caregivers to children with several inherited metabolic and mitochondrial disorders, as well as an undiagnosed disease. Our analysis yielded three superordinate themes: Reckoning With the Parent-Caregiver Role, Familial Transition, and Adaptation and Adjustment. Subordinate themes expanded upon these concepts and included distinctions between the parent and caregiving identity, communal coping and shifting of family dynamics, as well as meaning applied to child milestones, anticipatory grief, and parental perception of a new normal. Exploration of these themes in relation to existing literature, as well as future research directions for qualitative research on rare disease caregivers, is discussed. Overall, this work contributes to a growing body of literature exploring the parental experience of rare disease across several condition contexts.

Professional activity, gender and disease-related emotions: The impact on parents' experiences in caring for children with phenylketonuria

INTRODUCTION

Clinical management of rare diseases often fails to acknowledge the challenges faced by caregivers. Whilst management of phenylketonuria (PKU) may not be considered as dire as other conditions, most studies primarily concentrate on clinical issues, dietary adherence, or the quality of life of the PKU patients, leaving caregivers in the background. The aim of the study was to evaluate the psychosocial effects of PKU on family caregivers.

METHODS

Between October 30th, 2022 and February 28th, 2023, we collected data from caregivers of children with PKU using an anonymous, self-administered, computer-assisted online questionnaire. The survey was distributed among to patients during their regular visits to five Polish PKU treatment centers.

RESULTS

A total of 159 Polish caregivers of children with PKU completed the survey. This research shows that while women caregivers were more likely to be unemployed due to their responsibilities for childcare (50.3% compared to 0% for men), and men caregivers were more likely to be employed full-time (93.8% compared to 40.6% for women), the former reported higher emotional engagement in caregiving (88.1% vs 56.3% respectively). Significantly, unemployed mothers reported higher levels of loneliness, helplessness, and emotional control problems, and lacked psychological/emotional support more often than employed mothers. This research also shows a statistically significant positive correlation between mothers' education level and financial situation (p < 0.05) and education level and professional activity (p < 0.01). Additionally, a significant positive correlation was found between perceived financial situation and feeling of happiness (p < 0.001), and between financial situation and professional activity (p < 0.001). Finally, a significant positive correlation was observed between feeling of happiness and professional activity (p < 0.05).

CONCLUSIONS

According to our findings, there is a link between subjective happiness, financial situation, and professional activity among female caregivers. The relationship between these factors goes beyond just the income earned from work. The results of our study imply that there could even be a therapeutic advantage for working mothers. It is crucial to recognize the emotional difficulties that employed mothers may experience while taking care of a child with PKU, and to provide them with the necessary assistance and resources to meet their needs. Additionally, our results may provide a foundation for redefining the support system for caregivers in Poland.

Life story of Iranian parents of a child with phenylketonuria: a qualitative study

Parents of a child with phenylketonuria (PKU) face many challenges in childcare. It is crucial for health care workers to understand the situation of parents of a child with PKU and their needs. The purpose of this study was to explore the life story of parents with a child with PKU. This qualitative study has been done with a conventional content analysis approach. Twenty-four parents were selected purposefully. A semi-structured interview was conducted. Data analysis identified three main themes, which included parental reactions, consequences of a child with PKU in parents, and parents' needs. Parents of children with PKU can be considered people at risk for mental health because of their feelings of isolation and their lonely struggle to manage the disease and its effects on their child. This study shows that mothers need more support due to the misconceptions in and attitudes of their social environment. Therefore, it is necessary to understand this group, their needs and lives, and provide further support and promote empathy in the health system for the parents.

Mothers' lived experience of caring for children with inborn errors of amino acid metabolism

BACKGROUND

Inborn errors of amino acid metabolism are chronic conditions that have many sequels. Mothers of these children are facing different challenges which are underdetermined. This study was done to explore lived experience of mothers caring for these children.

METHODS

This is an interpretive phenomenology with van Manen's approach which has 6 steps. Data were gathered by convenience and purposeful sampling. Nine mothers with different experiences were interviewed and the interviews were audiotaped.

RESULTS

Six final themes were revealed from the exploring mothers' experiences including the future tied to the past, psychosis in the shadow of a lost ideal child, rebellion and blaming, the ways of escaping difficulties, self-forgetting in the shadow of full-time care, passing difficulties in the duality of hope-hopelessness, caring in a continuum of isolation-socialization.

CONCLUSION

Mothers have multiple challenges in taking care of their children, especially psychologically and financially. So, nurses must plan programs for helping mothers of children with inborn errors of amino acid metabolism to reduce the effects of disease on mothers and consequently the children and the whole family.

Psychological and Ethical Challenges of Introducing Whole Genome Sequencing into Routine Newborn Screening: Lessons Learned from Existing Newborn Screening

As a psychologist and an ethicist, we have explored empirically newborn screening consent and communication processes. In this paper we consider the impact on families if newborn screening uses whole genome sequencing. We frame this within the World Health Organization's definition of health and contend that proposals to use whole genome sequencing in newborn screening take into account the ethical, practical and psychological impact of such screening. We argue that the important psychological processes occurring in the neonatal phase necessitate a clear justification that providing risk information at this stage provides a health benefit. We illustrate how research on current newborn screening can inform whole genome sequencing debates, whilst highlighting important gaps. Obtaining explicit, voluntary, and sufficiently informed consent for newborn screening is challenging, however we stress that such consent is ethically and legally appropriate and psychologically and practically important. We conclude by outling how this might be done.

Individual and Family Determinants for Quality of Life in Parents of Children with Inborn Errors of Metabolism Requiring a Restricted Diet: A Multilevel Analysis Approach

OBJECTIVE

The objective of this study was to compare the quality of life (QoL) for parents of children with inborn errors of metabolism (IEMs) requiring a restricted diet with French population norms and investigate parental QoL determinants.

STUDY DESIGN

This cross-sectional study included mothers and/or fathers of children < 18 years of age affected by IEMs requiring a restricted diet (except phenylketonuria) from January 2015 to December 2017. Parents' QoL was assessed using the World Health Organization Quality of Life BREF questionnaire and compared with age- and sex-matched reference values from the French general population. Linear mixed models were used to examine the effects of demographic, socioeconomic, disease-related, and psychocognitive factors on parental QoL, according to a 2-level regression model considering individuals (parents) nested within families.

RESULTS

Of the 1156 parents invited to participate, 785 (68%) were included. Compared with the general population, parents of children with IEMs requiring a restricted diet reported a lower QoL in physical and social relationship domains but a higher QoL in the psychological domain. In the multivariate analysis, characteristics associated with poorer parental QoL included both parent-related factors (being a father, older age, more educated parent, nonworking parent, greater anxiety, seeking more social support, and using less positive thinking and problem-solving coping strategies) and family-related factors (disease complications, increased number of hospital medical providers, child's younger age, single-parent family, and lower family material wealth).

CONCLUSION

Parents of children with IEMs requiring a restricted diet reported poorer QoL in physical and social relationship domains than population norms. Psychocognitive factors, beyond disease-specific and family-related characteristics, were the most important determinants influencing parental QoL and may represent essential aspects for interventions.

Caregiver burden, and parents' perception of disease severity determine health-related quality of life in paediatric patients with intoxication-type inborn errors of metabolism

Background

Living with a non-acute (phenylketonuria) or acute (e.g. urea cycle disorders, organic acidurias) intoxication-type inborn error of metabolism (IT-IEM) can have a substantial impact on health-related quality of life (HrQoL) of paediatric patients and their families. Parents take primary responsibility for treatment monitoring and experience worry and fear about their child's health status. Quantitative evidence on parental psychological factors which may influence the HrQoL of patients with IT-IEM are sparse to non-existent.

Methods

In this multicenter survey study 50 parents of IT-IEM patients (ages 5–19) assessed the severity of their child's disease, reported on caregiver burden, and proxy-rated their child's HrQoL. Additionally, 35 patient self-reports on HrQoL were obtained (n = 16 female patients, n = 19 male patients). Multiple linear regressions were conducted to examine the predictive power of child age, sex, medical diagnosis type (acute / non-acute), parental perceived disease severity and caregiver burden on patients' HrQoL. Mediation analyses were used to investigate the relation of caregiver burden and parental ratings of disease severity with patients' HrQoL.

Results

Significant regression models for self-reported [F(5,34) = 10.752, p < .001, R² adj.^. = 0.59] and parent proxy reported HrQoL [F(5,49) = 20.513, p < .001, R² adj.^. = 0.67] emerged. High caregiver burden and perceived disease severity predicted significantly lower patient self- and proxy-reported HrQoL while type of diagnosis (acute versus non-acute) did not. Female sex predicted significantly lower self-reported HrQoL. High caregiver burden was the mediating factor between high perceived severity of the child's disease and lower proxy- by parent rated HrQoL.

Conclusion

Detecting elevated burden of care and providing support for parents seems crucial to prevent adverse consequences for their children's HrQoL. Intervention studies are needed, to assess which support programs are most efficient.

•

Caregiver burden enforced by high parent-perceived disease severity is a considerable risk factor for low HrQoL in paediatric patients with IT-IEM.

•

The parent perspective was a better estimator for the impact of disease than the mere medical type of diagnosis.

•

Female sex predicted lower self-reported HrQoL

"Why them, why me, why us?" The experiences of parents of children with lysosomal acid lipase deficiency: an interpretative phenomenological analysis study

BACKGROUND

Lysosomal acid lipase deficiency (LALD) is an ultra-rare, inherited metabolic disease within the category of lysosomal storage disorders, affecting an infant's ability to metabolise cholesterol. Developments in treatment, including Enzyme Replacement Therapy, have proven successful, with some children living for a number of years with treatment, although the future still remains unknown. The aim of this study was to explore the lived experiences of parents of children with LALD.

MAIN TEXT

Participants were recruited from across the United Kingdom between 2020 and 2021. Eight parents (five mothers and three fathers) whose child had a confirmed diagnosis of LALD were interviewed. Data collected from the semi-structured interviews were audio-record, transcribed and analysed using Interpretative Phenomenological Analysis (IPA). Three superordinate and nine subordinate themes emerged from the data: (1) Uncertainty-a double-edged sword (plunged into an uncertain world, living life with worry and walking the tightrope of stability), (2) Powerless against a shared battle with LALD (a helpless parent, a joint battle, protection against distress and a vulnerable parent needing help) and 3) Accepting a life with LALD (coming to terms with a diagnosis of LALD and a hidden condition).

CONCLUSIONS

The findings of this study highlight that the diagnosis of LALD proves to be a very challenging and emotionally distressing time in parents' lives, with increased uncertainty about what the future will hold for their child. This study signified the importance of healthcare pathways and service provisions to support parents and their children throughout diagnosis and beyond.

Pain points in parents' interactions with newborn screening systems: a qualitative study

Background & Objectives

This study aims to explore and elucidate parents’ experience of newborn screening [NBS], with the overarching goal of identifying desiderata for the development of informatics-based educational and health management resources.

Methods

We conducted four focus groups and four one-on-one qualitative interviews with a total of 35 participants between March and September 2020. Participants were grouped into three types: parents who had received true positive newborn screening results; parents who had received false positive results; and soon-to-be parents who had no direct experience of the screening process. Interview data were subjected to analysis using an inductive, constant comparison approach.

Results

Results are divided into five sections: (1) experiences related to the process of receiving NBS results and prior knowledge of the NBS program; (2) approaches to the management of a child’s medical data; (3) sources of additional informational and emotional support; (4) barriers faced by parents navigating the health system; and (5) recommendations and suggestions for new parents experiencing the NBS process.

Conclusion

Our analysis revealed a wide range of experiences of, and attitudes towards the newborn screening program and the wider newborn screening system. While parents’ view of the screening process was – on the whole – positive, some participants reported experiencing substantial frustration, particularly related to how results are initially communicated and difficulties in accessing reliable, timely information. This frustration with current information management and education resources indicates a role for informatics-based approaches in addressing parents’ information needs.

Italian national consensus statement on management and pharmacological treatment of phenylketonuria

BACKGROUND

Phenylketonuria (PKU) is a rare inherited metabolic disorder caused by defects in the phenylalanine-hydroxylase gene (PAH), the enzyme catalyzing the conversion of phenylalanine to tyrosine. PAH impairment causes phenylalanine accumulation in the blood and brain, with a broad spectrum of pathophysiological and neurological consequences for patients. Prevalence of disease varies, with peaks in some regions and countries, including Italy. A recent expert survey described the real-life of clinical practice for PKU in Italy, revealing inhomogeneities in disease management, particularly concerning approach to pharmacotherapy with sapropterin hydrochloride, analogous of the natural PAH co-factor, allowing disease control in a subset of patients. Therefore, the purpose of this paper is to continue the work initiated with the expert survey paper, to provide national guidances aiming to harmonize and optimize patient care at a national level.

PARTICIPANTS

The Consensus Group, convened by 10 Steering Committee members, consisted of a multidisciplinary crowd of 46 experts in the management of PKU in Italy.

CONSENSUS PROCESS

The Steering Committee met in a series of virtual meeting in order to discuss on clinical focuses to be developed and analyzed in guidance statements, on the basis of expert practice based evidence, large systematic literature review previously performed in the expert survey paper, and evidence based consensus published. Statements were re-discussed and refined during consensus conferences in the widest audience of experts, and finally submitted to the whole consensus group for a modified-Delphi voting.

RESULTS

Seventy three statements, divided in two main clinical areas, PKU management and Pharmacotherapy, achieved large consensus in a multidisciplinary group of expert in different aspects of disease. Importantly, these statements involve guidances for the use of sapropterin dihydrochloride, still not sufficiently implemented in Italy, and a set of good practice to approach the use of novel enzyme replacement treatment pegvaliase.

CONCLUSIONS

This evidence-based consensus provides a minimum set of guidances for disease management to be implemented in all PKU centers. Moreover, these guidances represent the first statement for sapropterin dihydrochloride use, implementation and standardization in Italy, and a guide for approaching pegvaliase treatment at a national level on a consistent basis.

Long-term cognitive and psychosocial outcomes in adults with phenylketonuria

Previous studies have suggested that cognitive and psychosocial underfunctioning in early-treated adults with phenylketonuria (PKU) may be explained by suboptimal adherence to dietary treatments, however, these studies often employ small samples, with different outcome measures, definitions and cut-offs. Samples have also tended to comprise participants with a limited range of blood phenylalanine concentrations, and often individuals who may not have been treated early enough to avoid neurological damage. In this study, we explore the impact of lifetime dietary control, as indicated by blood phenylalanine concentrations in childhood, adolescence and adulthood, on long-term cognitive and psychosocial outcomes in a large sample of adults with PKU who were diagnosed by neonatal screening and commenced on dietary treatment within the first month of life. One hundred and fifty-four participants underwent cognitive testing, assessing attention, learning, working memory, language, executive functioning and processing speed. One hundred and forty-nine completed measures of psychosocial functioning, documenting educational, occupational, quality of life, emotional and social outcomes which were compared with a group of healthy controls. Many adults with PKU demonstrated cognitive impairments, most frequently affecting processing speed (23%), executive function (20%) and learning (12%). Cognitive outcomes were related to measures of historic metabolic control, but only processing speed was significantly related to phenylalanine concentration at the time of testing after controlling for historic levels. Adults with PKU did not, however, differ from controls in educational, occupational, quality of life or emotional outcomes, or on a measure of family functioning, and showed only minor differences in relationship style. These findings have implications for patient counselling and decisions regarding the management of PKU in adulthood.

Absorbing it all: A meta-ethnography of parents' unfolding experiences of newborn screening

In a context of increasing international dialogue around the appropriate means and ends of newborn screening programmes, it is critical to explore the perspectives of those directly impacted by such screening. This meta-ethnography uses a systematic review process to identify qualitative studies that focus on parents' experiences of newborn screening published in English-language academic journals from 2000 to 2019 (n = 36). The included studies represent a range of moments, outcomes, and conditions that illuminate discrete elements of the newborn screening journey. We draw on these varied studies to construct a diagram of possible newborn screening pathways and through so-doing identify a critical window of time between the signalling of a positive newborn screen and the end of the screening process. During this critical window of time, families navigate complex emotional reactions, information, and decisions. From an in-depth analysis of this data, we develop the concept of "absorptive capacity" as a lens through which to understand parents' responses to new and emerging information. Alongside this, we identify how the "concertinaing of time" - the various ways that parents experience the expansion and compression of time throughout and beyond the screening pathway - affects their absorptive capacities. This study underscores the need to move away from viewing newborn screening as a discrete series of clinical events and instead understand it as a process that can have far-reaching implications across time, space, and family groups. Using this understanding of screening as a starting point, we make recommendations to facilitate communication and support for screened families, including the antenatal provision of information to parents and accommodations for the fluctuations in parents' absorptive capacities across the screening trajectory.

The Impact of the COVID-19 Pandemic on the Perception of Health and Treatment-Related Issues among Patients with Phenylketonuria in Poland-The Results of a National Online Survey

There is agreement that the pandemic has affected the healthcare system and behaviour of patients. This study aims to identify problems encountered by patients with phenylketonuria (PKU) and their parents/caregivers during the six-week pandemic lockdown in Poland (15 March to 30 April 2020). To determine the factors that influenced health and treatment-related issues, as well as the respondents’ perception of the impact of the pandemic, study participants were asked to complete a non-validated online questionnaire comprising 31 questions (including 27 single-choice, two multiple-choice and two open-ended ones). A total of 571 patients or their parents completed the questionnaire, with 9.5% of respondents not performing any blood phenylalanine (Phe) test in the analysed period, 21.3% declaring a blood Phe increase, and 15.3% a decrease. Increased problems in contacting the doctor or dietitian were reported by 26.1% of subjects, whereas 39.3% of them felt restricted access to dietary products. Most (63.4%) participants were satisfied with remote contact with their PKU clinic. Better compliance was associated with higher odds of acceptance of remote contact and of reporting fewer problems with contacting the doctor, and with lower odds of missing Phe testing. Self-reported high stress was associated with higher odds of reporting the limited availability of low-Phe products and Phe-free formulas, as well as with increased Phe concentrations and non-PKU-related health problems. These patients also had poor dietary compliance and experienced more problems in contacting specialists. Health and treatment-related problems experienced during the pandemic lockdown were related to a higher intensity of stress in patient’s family and worse therapy compliance before the pandemic. Previous experience of remote visits resulted in a better perception of this method of contact. It seems that this form of communication should be popularized and improved to increase therapy effectiveness in case of different limitations in the future. Special attention should be paid to vulnerable patients who may be at extra risk when the provision of standard care is affected.

Kleefstra syndrome: Impact on parents

BACKGROUND

Kleefstra syndrome (KS) is associated with developmental delay, autism, intellectual disability, psychosis, and regression. Research has not been conducted to assess the impact of KS on parents.

OBJECTIVE/HYPOTHESIS

A mixed-method study was conducted to assess the impact on parental well-being by evaluating parents' well-being, identifying factors of parental experience predicting well-being, and exploring the parental experience.

METHODS

Parents completed an online survey containing the PedsQL™ Family Impact Module (FIM) and a questionnaire created by the researchers. One-Way T-Test compared parents of children with KS to parents of children with Prader-Willi syndrome (PWS). Multiple linear regression used parents' total scale scores on PedsQL™ FIM to identify factors influencing parental well-being. Constant comparative analysis used open-ended responses to explore the parental experience of having a child with KS.

RESULTS

Parents of children with KS had statistically lower scores in daily activity and social functioning, but statistically higher scores in communication and emotional functioning compared to parents of children with PWS. However, the power was below 0.80, meaning additional research needs to be completed to confirm these findings. The linear multiple regression was not significant. Most importantly, the themes of establishing the diagnosis, importance of knowledge, sense of community, KS and relationships with others, how life changed, and what the future will hold, characterized the parental experience.

CONCLUSIONS

Knowledge and support were important to parents who had a child recently diagnosed with KS. Therefore, parents should be provided resources about KS and support groups at diagnosis.

Parental psychosocial aspects and stressors involved in the management of inborn errors of metabolism

Parents of children with inborn errors of metabolism (IEM) face numerous psychosocial challenges. An increased understanding and awareness of these stressors can ensure better overall outcomes for the entire family. We conducted semi-structured, in-person interviews with ten parents to identify psychosocial stressors, strategies, and supports they utilized to overcome their challenges. Our interview guide was designed to elicit familial experiences during the pre- and post-diagnosis periods. The themes and sub-themes were identified through qualitative descriptive textual analysis of audio-recorded transcripts. Major themes identified include ambiguity of illness, changing family and spousal dynamics, and navigating the healthcare system. Sub-themes revolved around disease effects, psychological stressors, health systems, support, and facing the disease. Healthcare professionals have an opportunity to minimize the impact of negative emotional outcomes by assisting families as they navigate the experience of having a child with an IEM. Our findings can be used to develop and continue a more well-rounded, family-oriented framework for IEM management.

Caring for a Child with Phenylketonuria: Parental Experiences from a Eurasian Country

OBJECTIVES

Phenylketonuria (PKU) and mild hyperphenylalaninemia (HPA) are characterized by increased blood phenylalanine concentrations varying from mild to severe. Management of PKU was reported to be time consuming and burdensome for caregivers. This study intended to explore the experiences of families caring for a child with PKU/HPA in a country with a high PKU rate. The aim of this study was to compare parental well-being between parents of children with and without dietary restrictions and to explore the factors associated with parental psychological well-being.

METHODS

Participants were interviewed about their experiences, concerns, and challenges related to the disease by using a semistructured questionnaire. After the interview, parents filled out the Beck Depression Inventory and State-Trait Anxiety Inventory-Trait.

RESULTS

This study highlighted the adverse psychological, financial, and social effects of the diagnosis and management of the disease regarding the lives of the families of children with PKU/HPA. Although parental anxiety scores of children with and without dietary restrictions were similar, depressive symptom scores were higher in parents of children with dietary restrictions. However, in multiple regression analysis, lower household income and absence of perceived social support were found to be independent factors associated with higher depressive symptom scores. Having a daughter diagnosed with PKU/HPA and lower household income were found to be factors associated with higher anxiety scores.

CONCLUSION

This study revealed that income level, perceived social support, and gender of the child were factors associated with psychological well-being of parents caring for children with PKU/HPA. Health care professionals should identify the challenges faced by families and should be aware of risk factors associated with lower parental well-being to achieve better family adjustment and better health outcomes.

Psychosocial functioning in children with phenylketonuria: Relationships between quality of life and parenting indicators

OBJECTIVE

This study aimed to assess the impact of phenylketonuria (PKU) and its treatment on parent and child health-related quality of life (HRQoL) and to identify the parenting-related correlates of parent and child HRQoL, as well as metabolic control.

METHODS

Eighteen mothers of 2- to 12-year-old children with PKU participated and completed a series of self-report questionnaires including the PKU Impact and Treatment Quality of Life Questionnaire (PKU-QOL).

RESULTS

Mothers reported that the most significant impact of PKU on HRQoL was in relation to the impact of their child's anxiety during blood tests on their own HRQoL and guilt related to poor adherence to dietary restrictions and supplementation regimens. Higher reported intensity of child emotional and behavioural difficulties and parenting stress were associated with higher scores for PKU symptoms on the PKU-QOL, higher scores for emotional, social, and overall impact of PKU, and higher scores for the impact of dietary restriction. Where mothers reported greater use of overreactivity as a parenting strategy, children tended to have better lifetime phenylalanine levels; however, the overall impact of PKU and the impact of supplement administration on mothers' HRQoL were worse for these families.

CONCLUSIONS

These findings have implications for a holistic family-centred approach to the care of children with PKU and their families.

Mealtime Anxiety and Coping Behaviour in Parents and Children During Weaning in PKU: A Case-Control Study

Solid food introduction may create anxiety for parents of children with phenylketonuria (PKU) due to the burden associated with protein substitute (PS) administration and natural protein restriction. In a longitudinal, prospective study, 20 mothers of children with PKU and 20 non-PKU control mothers completed 4 questionnaires (mealtime emotions, feed-time, Beck’s anxiety inventory and the coping health inventory for parents), examining parent/child mealtime emotions, anxiety, stress and coping strategies at child ages: weaning start, 8 months (m), 12 m, 15 m, 18 m and 24 m. Overall, mothers of children with PKU cope well with solid food introduction when applying a low-phenylalanine diet, with comparable low levels of stress and anxiety reported in both PKU and non-PKU groups. However, mothers of children with PKU reported peak scores in anxiety for emotive/cognitive symptoms at a child age of 15 m, and higher use of coping strategies at 15 m and 24 m (p < 0.05) of age. Generally, there was a trend that maternal anxiety regarding child rejection of PS increased with time, peaking between 12–24 m. In PKU, a child age of 12–18 m is identified as a key period when mothers feel most anxious/stressed with feeding, coinciding with raised blood phenylalanine levels probably associated with teething, illness and developing independence. Health professionals should be conscious of this vulnerable period and be prepared to offer more directional support as required.

What are the information needs of parents caring for a child with Glutaric aciduria type 1?

Background

Newborn screening has enabled the early diagnosis of Glutaric aciduria type 1, with the possibility of improving neurological outcomes in affected children. Achieving those outcomes requires parents to effectively manage their child’s condition by adherence to a strict dietary regime and responding to situations that may trigger decompensation. The specific information and support needs of this group of parents are unknown.

Methods

A focus group with five parents was conducted to gain insights into the information that parents needed and the ways in which they accessed and used information to manage their child’s condition. A topic guide was used to direct the discussion which was recorded and fully transcribed. All participants gave informed consent. Data were analysed using thematic analysis, a structured approach that contributes to transparency and validity of results while allowing the integration of predetermined and emerging themes. To ensure rigour, two researchers were involved in initial coding of data and key analytic decisions.

Results

Two main themes were identified. ‘Understanding the condition’ explored parent’s needs to understand the scientific complexity of the condition and to be aware of the worst case scenario associated with loss of metabolic control. ‘Managing the condition’ explained how parents co-ordinated and controlled the involvement of other carers and parents’ need to be active partners in medical management to feel in control of the situation.

Conclusions

The study highlights the importance of addressing parents’ initial and ongoing informational needs so they can fulfil their role and protect their child from metabolic harm.

Early feeding practices in infants with phenylketonuria across Europe

BACKGROUND

In infants with phenylketonuria (PKU), dietary management is based on lowering and titrating phenylalanine (Phe) intake from breast milk or standard infant formula in combination with a Phe-free infant formula in order to maintain blood Phe levels within target range. Professionals use different methods to feed infants with PKU and our survey aimed to document practices across Europe.

METHODS

We sent a cross sectional, survey monkey® questionnaire to European health professionals working in IMD. It contained 31 open and multiple-choice questions. The results were analysed according to different geographical regions.

RESULTS

Ninety-five centres from 21 countries responded. Over 60% of centres commenced diet in infants by age 10 days, with 58% of centres implementing newborn screening by day 3 post birth. At diagnosis, infant hospital admission occurred in 61% of metabolic centres, mainly in Eastern, Western and Southern Europe. Breastfeeding fell sharply following diagnosis with only 30% of women still breast feeding at 6 months.53% of centres gave pre-measured Phe-free infant formula before each breast feed and 23% alternated breast feeds with Phe-free infant formula. With standard infant formula feeds, measured amounts were followed by Phe-free infant formula to satiety in 37% of centres (n = 35/95), whereas 44% (n = 42/95) advised mixing both formulas together. Weaning commenced between 17 and 26 weeks in 85% centres, ≥26 weeks in 12% and < 17 weeks in 3%.

DISCUSSION

This is the largest European survey completed on PKU infant feeding practices. It is evident that practices varied widely across Europe, and the practicalities of infant feeding in PKU received little focus in the PKU European Guidelines (2017). There are few reports comparing different feeding techniques with blood Phe control, Phe fluctuations and growth. Controlled prospective studies are necessary to assess how different infant feeding practices may influence longer term feeding development.

Parenting a Child with Phenylketonuria: An Investigation into the Factors That Contribute to Parental Distress

Phenylketonuria (PKU) is an inherited metabolic condition that can lead to the onset of intellectual disabilities if not strictly managed through a low-protein diet. Parents are responsible for supervising their child's treatment for PKU, which may impact on their experience of distress. This cross-sectional study aimed to identify the factors that contribute to distress in parents who care for a child with PKU, distinct from parents in the general population. Thirty-eight parents of children and adolescents with PKU and 32 parents in the general population completed the questionnaires measuring parental psychological resilience, child behaviour problems, perceived social support and distress. Parents of children with PKU also completed measures of their child's care dependency and behaviour related to developmental and intellectual disabilities. The findings revealed no statistically significant differences in distress between the groups, but parents of children with PKU reported more child behaviour problems. Multiple regression analysis identified that parental psychological resilience and child anxious behaviour explained 35% of the variance in distress for parents of children with PKU. By comparison, parental psychological resilience and generic child behaviour only accounted for 19% of the variance in distress for parents in the general population. This has implications for developing interventions in clinical settings that aim to reduce parents' distress by enhancing their psychological resilience and supporting them to manage child behaviour difficulties, particularly anxious behaviour. Future research should include larger, more diverse samples and use longitudinal study designs.
