Background: Tuberous sclerosis complex (TSC) is a rare genetic condition commonly accompanied by neurological and neuropsychological disorders, resulting in a high burden of illness for individuals and a substantial impact on their caregivers. Due to the diversity and complexity of clinical manifestations, patients with TSC need aligned multidisciplinary healthcare services starting in childhood through to adulthood. However, patients and caregivers are sometimes dissatisfied with the care provided, for which one of the most common reasons is a lack of involvement in clinical decision-making. Shared decision-making, whereby clinicians make clinical management decisions together with patients and their caregivers, is advocated for in the management of epilepsy, but evidence of its benefit in managing TSC is currently lacking. In this cross-sectional, UK-based analysis we used an online survey to capture the experiences of primary caregivers for individuals with TSC, including the impact on work productivity, clinical shared decision-making, satisfaction with care, and the impact of the coronavirus disease 2019 (COVID-19) pandemic., Results: In total, 73 eligible caregivers provided consent (analysis set), with 14 completing the survey partially and 59 completing the full survey. Many caregivers (72%) reported receiving recommendations about new treatments from their doctor and discussing the treatment together, with a high proportion (89%) preferring that treatment was initiated at a low dose. Most caregivers (69%) were satisfied or extremely satisfied with pediatric TSC healthcare services, but only 25% were satisfied or extremely satisfied with the transition to adult TSC healthcare services. Several (n = 30) caregivers specified the impact of caring on their work productivity and career in optional open-ended survey responses. Finally, 80% of caregivers indicated that the COVID-19 pandemic had a "large" or "very large" impact on their caring activities, negatively affecting the emotional wellbeing and behavior of individuals with TSC, and caregivers' ability to work and arrange medical appointments., Conclusions: Caregivers largely feel involved in treatment decisions, and the majority were satisfied with healthcare services for children with TSC. However, many highlighted the need for an improved transition from pediatric to adult healthcare services. The survey also showed that COVID-19 has considerably affected caregivers and individuals with TSC., (© 2023. The Author(s).)

Background: Spinal muscular atrophy (SMA) is a rare neuromuscular disease that affects motor neurons, resulting in progressive skeletal muscle weakness and atrophy., Objective: The aim was to understand the value patients with SMA and caregivers place on treatment attributes and to estimate health utilities for SMA treatment outcomes from a general public sample., Methods: Two discrete choice experiments were designed to elicit treatment preferences and health utilities, respectively. Patients with Type 2 and non-ambulatory Type 3 SMA, caregivers of patients with SMA and a general public sample in the UK completed the surveys. Patients and caregiver participants were recruited through patient associations. General public participants were recruited via a survey recruitment panel. Attributes included motor function, breathing function, treatment administration, treatment reactions, eyesight monitoring, contraception (patients only) and overall survival (general public only). Clustered conditional logit models were used to estimate treatment preferences, and marginal rates of substitution were used to estimate disutilities., Results: Adult patients (n = 84) were twice as likely to choose a treatment with improved (vs. stable) motor and breathing function and four to five times less likely to choose a treatment with deteriorated (vs. stable) motor and breathing function as a treatment outcome. Caregivers (n = 83) were three to nine times more likely to choose improved and two to four times less likely to choose deteriorated (vs. stable) motor and breathing function. Both patients and caregivers preferred oral over intrathecal treatment. Treatment reactions, eyesight monitoring or contraception had no significant effect on patient choices. Conversely, caregivers preferred avoidance of treatment reactions. General public data (n = 506) yielded disutilities for unable to sit (- 0.408), need for > 16 h daily mechanical breathing support (- 0.304) and intrathecal therapy (- 0.071)., Conclusions: Study results show the importance of motor and breathing function to patients and caregivers, and an oral treatment preference. Disutilities (decrements to utility) were substantial for SMA disease outcomes and care aspects., (© 2021. The Author(s).)

Introduction: X-linked hypophosphatemia (XLH) is a rare, lifelong, progressive disease characterised by renal phosphate wasting and abnormal bone mineralisation. Symptoms begin in early childhood, with the development of rickets and related skeletal deformities and reduced growth, progressing to long-term complications, including pseudofractures and fractures, as well as pain, stiffness and fatigue. The present study was designed to explore the patient experience of pain, stiffness and fatigue and the psychosocial impact of XLH in detail., Methods: A cross-sectional qualitative study was conducted in the United Kingdom (18), Finland (6), France (4), Germany (1) and Luxembourg (1) with XLH patients aged 26 and over. Interview discussion guides were developed in consultation with clinical experts and patient associations. Data were analysed thematically., Results: Participants (N = 30) described pain, stiffness and fatigue as frequently experienced symptoms with a significant impact on physical functioning and activities of daily living (ADLs). Some also described the symptoms as impacting their mood/mental health, relationships, social life and leisure activities. Participants described how common symptoms could interact or aggravate other symptoms. Symptoms had often worsened over time, and for many, were associated with concern about the future. Most participants were worried or felt guilty about having children with XLH. The findings confirmed and extended the existing model of the burden of XLH., Conclusion: The present study is the first to provide an in-depth analysis of pain, stiffness and fatigue, their impact and the interrelatedness of these symptoms among adults with XLH. The study also described the psychosocial impact of XLH as a hereditary, lifelong progressive disease.
