Background: People with CF (pwCF) frequently have gastrointestinal symptoms (GI), including abdominal pain and irregular bowel movements. These are often embarrassing, difficult to report, and frequently missed. Thus, a GI Symptom Tracker was created and validated in the USA and translated and validated in Dutch. This questionnaire consists of four subscales: Eating Challenges, Stools, Adherence Challenges, and Abdominal Symptoms. The aim of this study was to investigate the relationship between GI symptoms, anxiety/depression, and health-related quality of life (HRQoL) in Dutch pwCF., Methods: In this prospective, cross-sectional single-center pilot study, pwCF completed the Dutch GI Symptom Tracker, GAD-7 (anxiety), PHQ-9 (depression), and CFQ-R (HRQoL) from September 2021 to June 2022. Regression analyses were used to analyze the univariable associations between GI symptoms, anxiety/depression, and HRQoL., Results: A total of 51 pwCF were enrolled consecutively (n = 41 adults, 66% female, mean age (y) [range] = 32.7 [19-71] and n = 10 adolescents, 70% female, mean age (y) [range] = 14.2 [12-17]). Elevated levels of anxiety (scores ≥ 10 on GAD-7) were found in 17% of adults and 0% of adolescents. Elevated depression scores (≥ 10 on PHQ-9) were found in 9% of adults and 20% of adolescents. GI scales "Abdominal Symptoms" and "Stools" were significantly, positively associated with elevated symptoms of anxiety and depression. Most GI scales were associated with lower HRQoL., Conclusion: This is the first study investigating the link between GI symptoms assessed by the Dutch GI Symptom Tracker and anxiety/depression and HRQoL in Dutch pwCF. More GI symptoms were associated with higher anxiety and depression scores and worse HRQoL. Additional research is needed to better understand how mental and physical health are linked in GI symptoms in CF., (© 2025 The Author(s). Pediatric Pulmonology published by Wiley Periodicals LLC.)

This is the final of four papers updating standards for the care of people with CF. That this paper "Planning a longer life" was considered necessary, highlights how much CF care has progressed over the past decade. Several factors underpin this progress, notably increased numbers of people with CF with access to CFTR modulator therapy. As the landscape for CF changes, so do the hopes and aspirations of people with CF and their families. This paper reflects the need to consider people with CF not as a "problem" to be solved, but as a success, a potential and a voice to be heard. People with CF and the wider CF community have driven this approach, reflecting many of the topics in this paper. This exercise involved wide stakeholder engagement. People with CF are keen to contribute to research priorities and be involved in all stages of research. People with CF want healthcare professionals to respect them as individuals and consider the impact of our actions on the world around us. Navigating life presents challenges to all, but for people with CF these challenges are heightened and complex. In this paper we highlight the concerns and life moments that impact people with CF, and events that the CF team should aim to support, including the challenges around having a family. People with CF and their care teams must embrace the updated standards outlined in these four papers to enjoy the full potential for a healthier life., Competing Interests: Declaration of competing interest The authors had no declarations of interest in relation to the current work.

Background: Elexacaftor/tezacaftor/ivacaftor (ETI) has been associated with unprecedented clinical improvements, transforming the management of cystic fibrosis (CF). However, side effects with implications for safety and well-being have been reported, including neuropsychiatric changes. This study aimed to better characterize the emerging positive and negative impacts of ETI., Methods: The Cystic Fibrosis Foundation's Mental Health Advisory Committee distributed a 26-item survey to US CF care teams to assess clinician observations of patient-reported experiences with ETI. Survey responses measured the prevalence of these effects in five domains: (1) positive physical and psychological effects, (2) sleep difficulties, (3) cognitive difficulties, (4) worsening mental health, and (5) concerns about the future and finances., Results: Seventy-five healthcare providers responded from a pediatric, adult, and combined centers. Positive physical effects of ETI and increased optimism were reported in the upper quartiles (50%-100%) and rated as having a significant impact on daily functioning. Sleep and cognitive difficulties were reported in 1%-24%, with slight impacts on functioning, and psychological symptoms (e.g., increased stress, depression, anxiety) and new psychiatric medications were reported in 1%-24%, with moderate impacts. Concerns about the future were reported in 1%-24%, with minimal impacts., Conclusion: Across US centers, providers most often observed positive physical effects of ETI. However, a variety of negative side effects were also reported, including sleep disruptions and worsening psychological functioning, which should be systematically monitored by CF teams. These national-level data are a first step in evaluating the prevalence and consequences of these side effects and can directly inform future studies., (© 2023 Wiley Periodicals LLC.)

Background: eHealth CF-CBT is the first digital mental health intervention for depression/anxiety in adults with cystic fibrosis (awCF); an 8-session therapist-guided internet-delivered program that was developed in English and Dutch with stakeholder input and evaluation indicating high acceptability and usability., Methods: Dutch eHealth CF-CBT was piloted in awCF with mild-moderate symptoms of depression and/or anxiety. Feasibility, usability, acceptability, and preliminary efficacy were assessed, measuring pre-post changes in depression (PHQ-9), anxiety (GAD-7), perceived stress (PSS), and health-related quality of life (CFQ-R)., Results: All participants (n = 10, seven female, mean age 29 [range 21-43], mean FEV1 71%pred [range 31-115]) completed all sessions. Patient-rated feasibility, usability, and acceptability of eHealth CF-CBT were positive on validated scales, as were qualitative assessments of content and format. GAD-7 improved in 90% of participants; in 50% by ≥the minimally important difference (MID) of four points. PHQ-9 improved in 90%; 40% by ≥the MID of 5. PSS improved in 80%. CFQ-R improved in the domain health perceptions (70%)., Conclusions: eHealth CF-CBT demonstrated feasibility, usability, acceptability, and promising preliminary efficacy in this pilot trial with Dutch awCF with mild to moderate symptoms of depression and anxiety., (© 2023 The Authors.

Background: The COVID-19 pandemic has spread across the world, leading to government measures associated with a negative impact on mental health. The aim of this study was to evaluate the impact of the pandemic on depression, anxiety and resilience in Dutch people with cystic fibrosis (PwCF) or primary ciliary dyskinesia (PwPCD) and their caregivers., Methods: Adolescents (12-17 years) and caregivers of children (0-17 years) with CF, and adolescents, adults and caregivers of children with PCD completed questionnaires on depression, anxiety and resilience between September 2020 and February 2021. The psychosocial impact of COVID-19 was measured by the Exposure and Family Impact Survey (CEFIS) Part 2. Mixed model analyses compared depression and anxiety results to participants' prepandemic scores., Results: One hundred ten participants (10 PwCF, 31 PwPCD, 52 CF caregivers, 17 PCD caregivers) completed questionnaires during the pandemic. Prepandemic outcomes were available for 87 participants. The prevalence of symptoms of depression and anxiety (PHQ-9 or GAD-7 scores ≥5) in PwCF and PwPCD and their caregivers before and during the pandemic was high, with an increase in depression in PwCF (2.75; 95% confidence interval: 0.82-4.68) and increase in anxiety in CF caregivers (1.03; 0.09-1.96) during the pandemic. Resilience was within the normal range for all groups, CEFIS scores corresponded to a low to normal impact., Conclusion: PwCF and PwPCD and their caregivers were at risk of elevated depression and anxiety symptoms both before and during the pandemic, which emphasizes the importance of mental health screening and psychological care in CF and PCD., (© 2023 The Authors.

Objectives: The CF Foundation sponsored competitive awards for Mental Health Coordinators (MHCs) from 2016 to 2018 to implement the international guidelines for mental health screening and treatment in US CF centers. Longitudinal surveys evaluated success in implementing these guidelines using the Consolidated Framework for Implementation Research (CFIR)., Methods: MHCs completed annual surveys assessing implementation from preparation/basic implementation (e.g., using recommended screeners) to full implementation/sustainability (e.g., providing evidence-based treatments). Points were assigned to questions through consensus, with higher scores assigned to more complex tasks. Linear regression and mixed effects models were used to: (1) examine differences in centers and MHC characteristics, (2) identify predictors of success, (3) model the longitudinal trajectory of implementation scores., Results: A total of 122 MHCs (88.4% responded): Cohort 1, N = 80; Cohort 2, N = 30; and Cohort 3, N = 12. No differences in center characteristics were found. Significant improvements in implementation were observed across centers over time. Years of experience on a CF team was the only significant predictor of success; those with 1-5 years or longer reported the highest implementation scores. Change over time was predicted by >5 years of experience., Conclusions: Implementation of the mental health guidelines was highly successful over time. Funding for MHCs with dedicated time was critical. Longitudinal modeling indicated that CF centers with diverse characteristics could implement them, supported by evidence from the CF Patient Registry showing nearly universal uptake of mental health screening in the United States. Years of experience predicted better implementation, suggesting that education and training of MHCs and retention of experienced providers are critical to success., (© 2023 Wiley Periodicals LLC.)

Psychological distress is prevalent in people with COPD and relates to a worse course of disease. It often remains unrecognised and untreated, intensifying the burden on patients, carers and healthcare systems. Nonpharmacological management strategies have been suggested as important elements to manage psychological distress in COPD. Therefore, this review presents instruments for detecting psychological distress in COPD and provides an overview of available nonpharmacological management strategies together with available scientific evidence for their presumed benefits in COPD. Several instruments are available for detecting psychological distress in COPD, including simple questions, questionnaires and clinical diagnostic interviews, but their implementation in clinical practice is limited and heterogeneous. Moreover, various nonpharmacological management options are available for COPD, ranging from specific cognitive behavioural therapy (CBT) to multi-component pulmonary rehabilitation (PR) programmes. These interventions vary substantially in their specific content, intensity and duration across studies. Similarly, available evidence regarding their efficacy varies significantly, with the strongest evidence currently for CBT or PR. Further randomised controlled trials are needed with larger, culturally diverse samples and long-term follow-ups. Moreover, effective nonpharmacological interventions should be implemented more in the clinical routine. Respective barriers for patients, caregivers, clinicians, healthcare systems and research need to be overcome., Competing Interests: Conflict of interest: E.

Sulfate is the fourth most abundant anion in human plasma but is not measured in clinical practice and little is known about the consequences of sulfate deficiency. Nevertheless, sulfation plays an essential role in the modulation of numerous compounds, including proteoglycans and steroids. We report the first patient with a homozygous loss-of-function variant in the SLC13A1 gene, encoding a renal and intestinal sulfate transporter, which is essential for maintaining plasma sulfate levels. The homozygous (Arg12Ter) variant in SLC13A1 was found by exome sequencing performed in a patient with unexplained skeletal dysplasia. The main clinical features were enlargement of joints and spondylo-epi-metaphyseal radiological abnormalities in early childhood, which improved with age. In addition, autistic features were noted. We found profound hyposulfatemia due to complete loss of renal sulfate reabsorption. Cholesterol sulfate was reduced. Intravenous N-acetylcysteine administration temporarily restored plasma sulfate levels. We conclude that loss of the SLC13A1 gene leads to profound hypersulfaturia and hyposulfatemia, which is mainly associated with abnormal skeletal development, possibly predisposing to degenerative bone and joint disease. The diagnosis might be easily missed and more frequent., (© 2022 The Authors. Clinical Genetics published by John Wiley & Sons Ltd.)

Cystic fibrosis (CF) has entered the era of variant-specific therapy, tailored to the genetic variants in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. CFTR modulators, the first variant-specific therapy available, have transformed the management of CF. The latest standards of care from the European CF Society (2018) did not include guidance on variant-specific therapy, as CFTR modulators were becoming established as a novel therapy. We have produced interim standards to guide healthcare professionals in the provision of variant-specific therapy for people with CF. Here we provide evidence-based guidance covering the spectrum of care, established using evidence from systematic reviews and expert opinion. Statements were reviewed by key stakeholders using Delphi methodology, with agreement (≥80%) achieved for all statements after one round of consultation. Issues around accessibility are discussed and there is clear consensus that all eligible people with CF should have access to variant-specific therapy., (Copyright © 2022.

Background: Primary ciliary dyskinesia (PCD) might be a risk factor for the development of anxiety and depression. This study investigated the associations between anxiety, depression and health-related quality of life (HRQoL) in individuals with PCD and their caregivers., Methods: Children, adolescents and adults with PCD and their caregivers were invited to participate in a mental health screening programme. During regular yearly outpatient visits, measures of anxiety (GAD-7), depression (PHQ-9), HRQoL (QOL-PCD), lung function (forced expiratory volume in 1 s (FEV 1 )) and body mass index (BMI)) were collected and associations of anxiety, depression and HRQoL were estimated., Results: A total of 103 individuals participated in the mental health screening programme. Elevated levels of anxiety (scores ≥10 on GAD-7) were found in 6% of adults (n=33), 14% of children (n=7), 6% of adolescents (n=17) and 20% of caregivers (n=46, 52% of mothers). Elevated depression levels (scores ≥10 on PHQ-9) were found in 18% of adults, 14% of children, 6% of adolescents and 11% of caregivers. Anxiety and depression were associated with scales on the QOL-PCD. Mothers reported higher anxiety scores than fathers (30% versus 9%, p=0.03). A strong negative relationship was found between depression in caregivers and physical functioning (QOL-PCD) of the child. Anxiety and depression were not significantly associated with anxiety/depression in their child., Conclusion: This is the first study investigating anxiety and depression in individuals with PCD and their caregivers. Our results revealed elevated levels of anxiety and depression, which were associated with worse HRQoL. These results suggest the need for psychological support in PCD., Competing Interests: Conflict of interest: M. Verkleij has nothing to disclose. Conflict of interest: I.

Introduction: Individuals with cystic fibrosis (CF) are at increased risk for anxiety and depression, with negative consequences for adherence, health, and quality of life. New approaches to prevent and treat anxiety and depression that are tailored to the concerns of this population are needed. A CF-specific internet-based cognitive-behavioral therapy (CBT) intervention was developed to increase access to evidence-based mental health care and decrease cost and burden of care for people with CF., Objective: To evaluate the usability and acceptability of "eHealth CF-CBT," an internet-based program integrating therapist-guided online self-management modules with in-person or virtual sessions., Methods: Dutch adults with CF ( N  = 16) and CF health care providers (N = 16) systematically tested all sessions of the eHealth CF-CBT program, provided qualitative feedback, and completed measures including eHealth Impact Questionnaire (eHIQ), and System Usability Scale (SUS)., Results: Patient and provider ratings of their overall impression of the eHealth CF-CBT program were high, with scores (mean; SD) of 8.3; 0.6 and 8.2; 0.8 respectively on a 10-point scale. Mean ratings of usability by patients (77.0/100) and providers (73.4/100) surpassed the SUS cut point for good favorability. Ratings (pooled mean; SD) on the assessed eHIQ domains Motivation and Confidence to Act (71.3; 10.0), Information and Presentation (78.9; 9.6), and Identification (62.0; 15.1) were positive, as were assessments of specific elements of session content and format., Conclusions: eHealth CF-CBT is the first therapist-guided internet-delivered CBT-based intervention for adults with CF. Initial evaluation with key stakeholders demonstrated high levels of acceptability and usability and provided input that was integrated to strengthen the program. Effectiveness testing in the Netherlands will be the next step, as well as future international adaptation and dissemination., Competing Interests: The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: This study was funded by Vertex Pharmaceuticals, Inc. via Circle of Care charitable awards and by research grants from the Cystic Fibrosis Foundation Therapeutics, Inc. and the Dutch Cystic Fibrosis Foundation.

Objective: To evaluate the efficacy of an online psychosocial group intervention for parents of children with a chronic illness, in terms of anxiety and depression, and disease-related coping skills., Methods: Parents (N = 73) participated in a parallel multicenter randomized controlled trial comparing an intervention group to a waitlist control group. In the group intervention Op Koers Online (English: On Track Online) parents learned how to use adaptive coping strategies taught with cognitive behavioral therapy and acceptance and commitment therapy techniques. Assessments (online questionnaires) took place at baseline (T0), 6-months (T1), and 12-months (T2) follow-up. Mixed-model analyses were performed to test the difference in change in outcomes between intervention (N = 34) and waitlist control group (N = 33)., Results: When compared with the waitlist control group, the intervention had a significant positive effect (p < .05) on changes in anxiety, depression, and total score T1 versus T0 (β = -.47 to -.51) and T2 versus T0 (β = -.39 to -.46), the coping skills open communication, relaxation, social support, acceptance, predictive control (β = .42-.88) and helplessness (β = -.47) T1 versus T0 and relaxation and positive thinking T2 versus T0 (β = .42-.53)., Conclusions: Parental anxiety and depression decreased, and use of adaptive coping skills improved after the intervention. The online character, the focus on parents themselves instead of on their child and the possibility for parents of children with rare illnesses to participate, are innovative and unique aspects of Op Koers Online for parents. The next step is to implement the intervention in clinical practice., (© The Author(s) 2020. Published by Oxford University Press on behalf of the Society of Pediatric Psychology.)

Background: The International Committee on Mental Health (ICMH) published screening guidelines in Cystic Fibrosis (CF). This work 1) evaluated the sensitivity of the recommended screening tools against the 'gold standard' clinical psychological assessment and 2) investigated referral and treatment pathways., Methods: Ninety-six participants (79 caregivers; 17 adolescents with CF) completed the screening tools prior to formal assessment. Agreement between screening data and psychological assessment was evaluated, sensitivity analyses performed and referral pathways tracked., Results: All participants with an elevated screen (moderate/severe range) were subsequently assessed as requiring treatment for major depression/anxiety disorders. However, many were referred for treatment without elevated scores. Hence, sensitivity was poor with the recommended threshold score of 10, but with a threshold of 5 the sensitivity was 76% for adults and 46% for adolescents. The area under the ROC curve (diagnostic test ability) was 0.89 for caregivers but lower at 0.68 for adolescents., Conclusion: Mental health screening is complex, particularly in adolescents. Nonetheless, it is a first valuable step to improve mental health care in CF. The need for psychological support is greater than anticipated by the TIDES study., (Copyright © 2018 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.)
