BACKGROUND: In health, nitric oxide (NO) shows high concentrations in the upper airways, while nasal NO (nNO) is significantly lower in patients with sinonasal inflammation, such as people with cystic fibrosis (PwCF). In PwCF treated with elexacaftor/tezacaftor/ivacaftor (ETI; PwCF-ETI), clinical improvement of sinonasal symptoms and inflammation was observed. We therefore hypothesised that ETI may increase nNO in PwCF. METHODS: 25 PwCF-ETI underwent nNO measurement at baseline and after 3 to 24 months of ETI treatment...

Patients with Cystic Fibrosis (CF) are at increased risk of acute (AP) and chronic (CP) pancreatitis, and their complications. The extent of remaining healthy pancreatic parenchyma determines the risk of developing future episodes of pancreatitis, as well as pancreatic exocrine or endocrine insufficiency. Pancreatitis may be the presenting symptom of CF, and genetic testing is especially important in pediatrics. AP and recurrent AP are managed with intravenous fluid hydration and pain control, in addition to early refeeding and treatment of complications...

The purpose of the study was to assess the psychometric properties of the parent-report version of the Sibling Perception Questionnaire (SPQ) in well-siblings. Participants were 200 caregivers of healthy children ages 9-17 years who had a sibling (ages 0-18 years) diagnosed with cancer, diabetes, cystic fibrosis, epilepsy, spina bifida, or congenital heart disease. The SPQ had acceptable internal consistency reliability for the total score (α = 0.83) and displayed acceptable convergent validity as evidenced by medium to large positive correlations with the Strengths and Difficulties Questionnaire and Pediatric Quality of Life Inventory 4...

OBJECTIVE: Evaluate the influence of the BsmI polymorphism of the vitamin D receptor gene on vitamin D levels, and inflammatory and oxidative stress markers in patients with Cystic Fibrosis supplemented with cholecalciferol megadose. METHODS: We performed a single-arm, non-randomized pre- and post-study of 17 patients aged 5 to 20 years with cystic fibrosis diagnosed with vitamin D insufficiency/deficiency 25-hydroxy vitamin< 30 ng/mL. Individuals were genotyped for the BsmI polymorphism of the vitamin D receptor gene and all received cholecalciferol supplementation of 4,000 IU daily for children aged 5 to 10 years and 10,000 IU for children over 10 years of age for 8 weeks...

BACKGROUND AND OBJECTIVES: There are limited data on cystic fibrosis (CF) transmembrane conductance regulator-related metabolic syndrome (CRMS) outcomes beyond infancy. The goal of this study was to analyze outcomes of infants with CRMS up to the age of 9-10 years using the CF Foundation Patient Registry (CFFPR). METHODS: We analyzed data from the CFFPR for individuals with CF and CRMS born between 2010 and 2020. We classified all patients based on the clinical diagnosis reported by the CF care center and the diagnosis using CFF guideline definitions for CF and CRMS, classifying children into groups based on agreement between clinical report and guideline criteria...

This cross-sectional quantitative study was conducted to evaluate the coping strategies of parents of children with cystic fibrosis. The research sample is the parents (n: 112) who presented to Thoracic Medicine Department at Hacettepe University Pediatric Hospital between 3 April 2021 - 28 May 2021 and volunteered to participate in the study. Sociodemographic Data Form and Coping Orientation to Problems Experienced Inventory (COPE Inventory) were used in the collection of data. The study examined coping strategies according to children's characteristics such as age, sex, education, and parents' independent variables such as employment status, income status, number of individuals and children in the family, communication with other families, social and financial support...

Cystic fibrosis (CF) is a multifaceted disorder predominantly investigated for its pulmonary manifestations, yet patients with CF also exhibit a spectrum of extrapulmonary manifestations, notably those involving the hepatobiliary system. The latter constitutes the third leading cause of morbidity and mortality in individuals with CF. Cystic fibrosis-related liver disease (CFLD), with an escalating prevalence, manifests diverse clinical presentations ranging from hepatomegaly to cirrhosis and hepatopulmonary syndrome...

PURPOSE: The mechanism of the impact of religion on health is still unclear, especially in children and adolescents with chronic illness who live in religious contexts. This study aimed to understand the influence of religion on coping with chronic diseases from the perspective of hospitalized children and adolescents diagnosed with cancer, type 1 diabetes mellitus and cystic fibrosis. DESIGN AND METHODS: Qualitative descriptive research used photo-elicitation interviews with 35 Brazilian children and adolescents with cancer, type 1 diabetes mellitus and cystic fibrosis, aged between 7 and 17 years old...

BACKGROUND: Williams Beuren Syndrome (WBS) is a well-recognized and common genetic cause of congenital heart defects, developmental delay, hypercalcemia, and characteristic facial features. It is caused by a 1.5 - 1.8 Mb heterozygous deletion of chromosome 7q11.23 with loss of around 28 coding genes. The aim of this study was to develop a low-cost, semi-quantitative PCR (sqPCR) method to detect the chromosome 7q11.23 deletion. METHODS: Twenty-four suspected WBS cases were recruited following ethical clearance and informed consent...

AIMS: The aim was to evaluate whether standardised exercise performance during the incremental shuttle walk test (ISWT) can be used to assess disease severity in children and young people (CYP) with chronic conditions, through (1) identifying the most appropriate paediatric normative reference equation for the ISWT, (2) assessing how well CYP with haemophilia and cystic fibrosis (CF) perform against the values predicted by the best fit reference equation and (3) evaluating the association between standardised ISWT performance and disease severity...

INTRODUCTION: Cystic fibrosis (CF) treatment has increasingly focused on highly effective modulators. Despite measurable benefits of modulators, there is little guidance for CF care team members on providing education and support to patients regarding initiation of these therapies. We aimed to explore patient, caregiver, and clinician perceptions of modulators and influences on decisions about starting cystic fibrosis transmembrane regulator (CFTR) modulators. METHODS: We conducted semistructured interviews with CF clinicians, adults with CF, and caregivers of children with CF...

Since screening for cystic fibrosis (CF) was incorporated into the newborn screening program, the number of recognised variants in the CF transmembrane conductance regulator (CFTR ) gene has significantly increased. This has led to the discovery of combinations of gene variants with an uncertain prognosis. One outcome is the designation of 'cystic fibrosis screen positive inconclusive diagnosis' (CFSPID). While the majority of these children are expected to be unaffected by their CFTR variants, a small proportion have been seen to develop symptoms or increasing sweat chloride levels over time, which may reflect dysfunction of the CFTR protein...

BACKGROUND: In 2016, nationwide cystic fibrosis newborn screening (CFNS) was newly implemented in Germany, using an immunoreactive trypsin/pancreatitis-associated protein/DNA screening algorithm that differs from most other nationwide screening programmes. METHODS: We analysed real-life feasibility of the confirmation process with respect to our pre-specified procedural objectives. These included overall accuracy through false-negative and false-positive results, effectiveness of the Bavarian tracking system, and accuracy of Macroduct and Nanoduct sweat conductivity compared with quantitative chloride determination...

BACKGROUND: Nephronophthisis (NPHP) is a genetically heterogeneous disease that can lead to end-stage renal disease (ESRD) in children. The TTC21B variant is associated with NPHP12 and mainly characterized by cystic kidney disease, skeletal malformation, liver fibrosis, and retinopathy. Affected patients range from children to adults. Some patients experience ESRD in infancy or early childhood, but clinical reports on neonatal patients are rare. We report a case of NPHP12 in a premature infant and analyze its genetic etiology...

DNA alterations in gametes, which may occur either spontaneously or as a result of exposure to genotoxicants, can lead to constitutional chromosomal anomalies in the offspring. Alcohol is an established genotoxicant. The goal of this hypothesis-testing longitudinal cohort study was to evaluate the effect of significant/sustained maternal alcohol exposure on clinically diagnosed constitutional chromosomal anomalies among children diagnosed with fetal alcohol syndrome (FAS). De-identified eligibility and claim healthcare records, prospectively generated from the 1990-2012 Florida Medicaid system within the Independent Healthcare Research Database (IHRD), were analyzed...

Cystic fibrosis (CF) is a multisystemic disease in which airway obstruction, infection, and inflammation play a critical role in the pathogenesis and progression of CF lung disease. The carbohydrate-binding protein Galectin-3 is increased in several inflammatory and fibrotic diseases and has recently been forwarded as a biomarker in these diseases. We aimed to define the role of serum Galectin-3 in children with CF by comparison with healthy subjects. This is a cross-sectional, case-control study. 143 CF and 30 healthy subjects were enrolled in the study...

Cystic fibrosis (CF) is a progressive, genetic, multi-organ disease affecting the respiratory, digestive, endocrine, and reproductive systems. CF can affect any aspect of the gastrointestinal (GI) tract, including the esophagus, stomach, small intestine, colon, pancreas, liver, and gall bladder. GI pathophysiology associated with CF results from CF membrane conductance regulator (CFTR) dysfunction. The majority of people with CF (pwCF) experience exocrine pancreatic insufficiency resulting in malabsorption of nutrients and malnutrition...

BACKGROUND: Elexacaftor in combination with Tezacaftor and Ivacaftor (ETI) became licensed in the United Kingdom in early 2022 for children aged 6-11 years with cystic fibrosis (CF) and an eligible mutation. Many in this age group have excellent prior lung health making quantitative measurement of benefit challenging. Clinical trials purport that lung clearance index (LCI2.5 ) measurement is most suitable for this purpose. OBJECTIVES: This study aimed to understand the clinical utility of LCI2...

BACKGROUND: Short palate, lung, and nasal epithelium clone 1 (SPLUNC1) is an innate defence protein that acts as an anti-microbial agent and regulates airway surface liquid volume through inhibition of the epithelial sodium channel (ENaC). SPLUNC1 levels were found to be reduced in airway secretions of adults with cystic fibrosis (CF). The potential of SPLUNC1 as a biomarker in children with CF is unknown. METHODS: We quantified SPLUNC1, interleukin-8 (IL-8) and neutrophil elastase (NE) in sputum of CF children treated with either intravenous antibiotics or oral antibiotics for a pulmonary exacerbation (PEx)s, and in participants of a prospective cohort of CF children with preserved lung function on spirometry, followed over a period of two years...
