RESUMO
Multiple breath washout (MBW) has successfully assessed the silent lung zone particularly in cystic fibrosis lung disease, however, it is limited to the communicating lung only. There are a number of different pulmonary function methods that can assess what is commonly referred to as trapped air, with varying approaches and sensitivity. Twenty-five people with cystic fibrosis (pwCF) underwent MBW, spirometry, body plethysmography, and spirometry-controlled computed tomography (spiro-CT) on the same day. PwCF also performed extensions to MBW that evaluate air trapping, including our novel extension (MBWShX), which reveals the extent of under-ventilated lung units (UVLU). Additionally, we used 2 previously established 5-breath methods that provide a volume of trapped gas (VTG). We used trapped air % from spiro-CT as the gold standard for comparison. UVLU derived from MBWShX showed the best agreement with trapped air %, both in terms of correlation (RS 0.89, P<0.0001) and sensitivity (79%). Bland-Altman analysis demonstrated a significant underestimation of the VTG by both 5-breath methods (-249ml [95%CI -10796; 580ml] and -203ml [95%CI -997;591ml], respectively). Parameters from both spirometry and body plethysmography were sub-optimal at assessing this pathophysiology. The parameters from MBWShX demonstrated the best relationship with spiro-CT and had the best sensitivity compared to the other pulmonary function methods assessed in this study. MBWShX shows promise to assess and monitor this critical pathophysiological feature, which has been shown to be a driver of lung disease progression in pwCF.
RESUMO
BACKGROUND: Pancreatic fibrosis is an early diagnostic feature of the common inherited disorder cystic fibrosis (CF). Many people with CF (pwCF) are pancreatic insufficient from birth and the replacement of acinar tissue with cystic lesions and fibrosis is a progressive phenotype that may later lead to diabetes. Little is known about the initiating events in the fibrotic process though it may be a sequela of inflammation in the pancreatic ducts resulting from loss of CFTR impairing normal fluid secretion. Here we use a sheep model of CF (CFTR-/-) to examine the evolution of pancreatic disease through gestation. METHODS: Fetal pancreas was collected at six time points from 50-days of gestation through to term, which is equivalent to ~ 13 weeks to term in human. RNA was extracted from tissue for bulk RNA-seq and single cells were prepared from 80-day, 120-day and term samples for scRNA-seq. Data were validated by immunochemistry. RESULTS: Transcriptomic evidence from bulk RNA-seq showed alterations in the CFTR-/- pancreas by 65-days of gestation, which are accompanied by marked pathological changes by 80-days of gestation. These include a fibrotic response, confirmed by immunostaining for COL1A1, αSMA and SPARC, together with acinar loss. Moreover, using scRNA-seq we identify a unique cell population that is significantly overrepresented in the CFTR-/- animals at 80- and 120-days gestation, as are stellate cells at term. CONCLUSION: The transcriptomic changes and cellular imbalance that we observe likely have pivotal roles in the evolution of CF pancreatic disease and may provide therapeutic opportunities to delay or prevent pancreatic destruction in CF.

Up to 90% of people with CF (pwCF) will have some form of hepatobiliary involvement. This manuscript aims to explore the different endovascular, endoscopic, radiological and surgical procedures available to diagnose and manage the most severe form of CF hepatobiliary involvement (CFHBI) known as advanced cystic fibrosis liver disease (aCFLD), seen in 10% of pwCF. These procedures and interventions include liver biopsy, hepatic venous pressure gradient measurement, gastrostomy tube placement to optimize nutrition, paracentesis, endoscopic variceal control of bleeding and portosystemic shunting before liver transplantation. By utilizing advanced diagnostic or surgical techniques, healthcare professionals of pwCF can more effectively manage patients with CFHBI and aCFLD and potentially improve patient outcomes.

Cystic Fibrosis (CF) is a progressive condition resulting in reduced lung function and strongly associated with elevated anxiety and depression symptoms. Self-concept refers to an individual's overarching sense of identity, a positive level of which is widely associated with reduced anxiety and depression. There is a significant lack of self-concept research within CF. This study explores the association between self-concept and anxiety and depression in adults with CF. 64 adults living with CF in Western Australia completed validated online questionnaires (Generalised Anxiety Disorder-7, Patient Health Questionnaire-9, Tennessee Self-Concept Questionnaire 2: Short-Form) and consented to the collection of medical data. Descriptive, t-test, correlation and multiple regression analysis were undertaken. Higher levels of self-concept were associated with lower levels of anxiety and depression symptoms. Lower self-concept levels were a significant predictor of increased anxiety and depression symptoms after accounting for physical health status. Mean self-concept scores for those who required mental health intervention were significantly lower compared to those that did not. This study identifies a significant relationship between self-concept and anxiety and depression in adults with CF. Further research is required to establish causation and test the feasibility of self-concept interventions in reducing anxiety and depression symptoms.
RESUMO
Over the last two centuries, great advances have been made in microbiology as a discipline. Much of this progress has come about as a consequence of studying the growth and physiology of individual microbial species in well-defined laboratory media; so-called "axenic growth". However, in the real world, microbes rarely live in such "splendid isolation" (to paraphrase Foster) and more often-than-not, share the niche with a plethora of co-habitants. The resulting interactions between species (and even between kingdoms) are only very poorly understood, both on a theoretical and experimental level. Nevertheless, the last few years have seen significant progress, and in this review, we assess the importance of polymicrobial infections, and show how improved experimental traction is advancing our understanding of these. A particular focus is on developments that are allowing us to capture the key features of polymicrobial infection scenarios, especially as those associated with the human airways (both healthy and diseased).

Background Cystic fibrosis (CF) is a genetic disorder of the cystic fibrosis transmembrane conductance regulator chloride channel that leads to impaired mucus clearance in the airways, which leads to deteriorations in lung function and chronic respiratory infection. These effects of CF contribute to the hypothesis that patients with CF may be at increased risk of complications when they catch coronavirus disease 2019 (COVID-19), which swept the world in a global pandemic starting in 2019. Overall, however, the role of CF in COVID-19 has not been well studied, particularly in pediatric patients. Methods In this retrospective review, pediatric patients with CF who contracted COVID-19 (3/1/2020-3/1/2023) (N=69) were compared to two equally sized control cohorts of patients with only CF or COVID-19 matched based on demographics and clinical baselines. Occurrences of adverse outcomes (emergency room visits, hospitalizations, CF pulmonary exacerbations, etc.) were assessed for each subject. The mean percentage of predicted forced expiratory volume in 1 second (FEV1%pred) was also assessed for CF patients. Fisher's exact test assessed differences between the proportions of subjects who experienced each outcome. Independent two-variable t-testing assessed mean FEV1%pred differences. Analysis was conducted using IBM SPSS Statistics for Windows, Version 29 (Released 2023; IBM Corp., Armonk, New York, United States) with a significance α=0.05. Ad hoc power analysis was conducted using G*Power v3.1. Results Overall, CF/COVID subjects fared similarly to control groups without either CF or COVID-19 history, including among subgroups stratified based on baseline respiratory function, P. aeruginosa colonization status, and COVID-19 vaccination status. One notable finding was that CF/COVID subjects experienced significantly fewer pulmonary exacerbations compared to CF-only subjects (p=0.004). Conclusion In conclusion, pediatric CF patients performed similarly to their peers without CF with regard to COVID-19 and generally did not demonstrate significant deteriorations in pulmonary function following infection. Lower incidence of pulmonary exacerbations in CF/COVID subjects could be explained by stringent monitoring by parents, quarantine, or close pulmonology follow-up. These findings will provide guidance on management and care for pediatric CF patients with COVID-19.
RESUMO
BACKGROUND: Racial and ethnic disparities in pediatric lung transplantation (LTx) related to the shifting cystic fibrosis (CF) population receiving highly effective modulator therapy (HEMT) has not been well investigated. METHODS: The UNOS Registry was queried for patients age 1-25 years undergoing bilateral LTx between 1 January 2012 and 31 December 2021. Race and ethnicity were classified as non-Hispanic White, non-Hispanic Black, Hispanic, or none of the above. The primary outcome was posttransplant mortality. Trends in the association between race/ethnicity and mortality were examined using transplant year as a continuous variable and stratifying year based on introduction of HEMT (triple combination therapy) in November 2019. RESULTS: In the study sample (N = 941), 7% of patients were non-Hispanic Black, 15% were Hispanic, and 2% were some other racial or ethnic group. One hundred (11%) received LTx after approval of triple combination therapy, and 407 (43%) died during follow-up. We identified a statistically significant disparity in mortality hazard (hazard ratio: 1.91; 95% confidence interval: 1.31, 2.80) in non-Hispanic Black compared to non-Hispanic White patients in the pre-triple combination therapy era. CONCLUSIONS: We found higher mortality hazard among non-Hispanic Black compared to non-Hispanic White children undergoing LTx in the United States. Further monitoring of LTx outcomes to identify and address disparities is needed in the current era of triple combination therapy for CF.
RESUMO
Introduction Cystic fibrosis (CF) leads to the impairment of multiple essential organs and systems in the human body. The objective of this study was to analyze the financial consequences of having cystic fibrosis (CF) on patients, evaluate their general state of health, and specifically investigate the impact of living expenses on their quality of life. Methods The data were collected using three tools and a form for personal information entry. The first questionnaire was employed to quantify fluctuations in patients' cost of living. The Greek variant of the Short Form Questionnaire-36 (SF-36) and the Greek version of the Cystic Fibrosis Quality of Life (CFQoL) were implemented to assess quality of life. Statistical significance was set at p < 0.05, and analyses were conducted using SPSS statistical software. Results The study obtained a response rate of 93.2%, with 105 participants consenting to and effectively finishing the questionnaire. The mean age of the patients was 32.1 years, with 46.7% being female and 53.3% being male. Medication was being administered to 46.7% of the patients. The condition incurred an average cost of 767 in the preceding semester. The maximum cost was 1007. Patients with a higher monthly family income and those who were taking medication exhibited superior physical performance and functional capacity. Conclusion The research emphasizes that implementing causative treatment and minimizing hospitalizations can potentially enhance life satisfaction. The findings suggest possible approaches to enhance the quality of life in people with cystic fibrosis, in conjunction with the implementation of novel or enhanced treatment modalities.
RESUMO
Cystic fibrosis (CF) is a genetic ailment caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. This autosomal recessive disorder is characterized by diverse pathobiological abnormalities, such as the disorder of CFTR channels in mucosal surfaces, caused by inadequate clearance of mucus and sputum, in addition to the malfunctioning of mucous organs. However, the primary motive of mortality in CF patients is pulmonary failure, which is attributed to the colonization of opportunistic microorganisms, formation of resistant biofilms, and a subsequent decline in lung characteristics. In December 2019, the World Health Organization (WHO) declared the outbreak of the radical coronavirus disease 2019 (COVID-19) as a worldwide public health crisis, which unexpectedly spread not only within China but also globally. Given that the respiration system is the primary target of the COVID-19 virus, it is crucial to investigate the impact of COVID-19 on the pathogenesis and mortality of CF patients, mainly in the context of acute respiratory distress syndrome (ARDS). Therefore, the goal of this review is to comprehensively review the present literature on the relationship between cystic fibrosis, COVID-19 contamination, and development of ARDS. Several investigations performed during the early stages of the virus outbreak have discovered unexpected findings regarding the occurrence and effectiveness of COVID-19 in individuals with CF. Contrary to initial expectancies, the rate of infection and the effectiveness of the virus in CF patients are lower than those in the overall population. This finding may be attributed to different factors, including the presence of thick mucus, social avoidance, using remedies that include azithromycin, the fairly younger age of CF patients, decreased presence of ACE-2 receptors, and the effect of CFTR channel disorder on the replication cycle and infectivity of the virus. However, it is important to notice that certain situations, which include undergoing a transplant, can also doubtlessly boost the susceptibility of CF patients to COVID-19. Furthermore, with an increase in age in CF patients, it is vital to take into account the prevalence of the SARS-CoV-2 virus in this population. Therefore, ordinary surveillance of CF patients is vital to evaluate and save the population from the capability of transmission of the virus given the various factors that contribute to the spread of the SARS-CoV-2 outbreak in this precise organization.
RESUMO
INTRODUCTION: 'Highly effective' modulator therapies (HEMTs) have radically changed the Cystic Fibrosis (CF) therapeutic landscape. AREAS COVERED: A comprehensive search strategy was undertaken to assess impact of HEMT in life of pwCF, treatment challenges in specific populations such as very young children, and current knowledge gaps. EXPERT OPINION: HEMTs are prescribed for pwCF with definite genotypes. The heterogeneity of variants complicates treatment possibilities and around 10% of pwCF worldwide remains ineligible. Genotype-specific treatments are prompting theratyping and personalized medicine strategies. Improvement in lung function and quality of life increase survival rates, shifting CF from a pediatric to an adult disease. This implies new studies addressing long-term efficacy, side effects, emergence of adult co-morbidities and possible drug-drug interactions. More sensitive and predictive biomarkers for both efficacy and toxicity are warranted. As HEMTs cross the placenta and are found in breast milk, studies addressing the potential consequences of treatment during pregnancy and breastfeeding are urgently needed. Finally, although the treatment and expected outcomes of CF have improved dramatically in high- and middle-income countries, lack of access in low-income countries to these life-changing medicines highlights inequity of care worldwide.

Cystic fibrosis (CF) is a recessively inherited disease most commonly seen in Caucasians. The mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene are responsible for the condition, and to date, more than 2000 mutations have been published in the literature. The most common mutation worldwide is F508del. Here, we reported a five-year-old child who presented to the clinic with a chronic cough. Her newborn screening for CF was negative, including 139 mutation panels done in India. The sweat chloride test was positive, and CF gene sequencing was reported as c.2489dup p. (Glu831GLYFS *5) homozygotes mutation in the CFTR gene (Online Mendelian Inheritance in Man (OMIM) *602421). To the best of our knowledge, this gene was first described and published in the literature.
RESUMO
BACKGROUND: Despite translational evidences suggesting that cystic fibrosis-related abnormal glucose tolerance (CF-related AGT) may begin early in life and is known to be associated with increased morbidity and mortality, current guidelines recommend screening for AGT only from 10 years of age, thus missing the opportunity for early detection and intervention. METHODS: A systematic review and meta-analysis (PROSPERO number: CRD42021282516) was conducted on studies that reported data on the prevalence of AGT or its subtypes in CF populations. Pooled proportions, risk, and odds ratios with 95 % confidence intervals (CI) were calculated. One-stage dose-response random-effect meta-analysis was used to assess the effect of age on CF-related diabetes (CFRD). RESULTS: The quantitative analysis included 457 studies and data from 520,544 patients. Every third child with CF (chwCF) (0.31 [95 % CI 0.25-0.37]) and every second adult with CF (awCF) (0.51 [95 % CI 0.45-0.57]) were affected by AGT. Even in the 5-10 years of age subgroup, the proportion of AGT was 0.42 [95 % CI 0.34-0.51]. The prevalence of prediabetes remained unchanged (impaired glucose tolerance in chwCF:0.14 [95 % CI 0.10-0.18]) vs. awCF:0.19 [95 % CI 0.14-0.25]), whereas the proportion of CFRD increased with age (0-5: 0.005 [95 % CI 0.0001-0.15]; 5-10: 0.05 [95 % CI 0.01-0.27]; 10-18: 0.11 [95 % CI 0.08-0.14]; >18 years of age: 0.27 [95 % CI 0.24-0.30]). CONCLUSION: CF-related AGT is common under 10 years of age. Our study suggests considering earlier AGT screening, starting from 5 years of age. This highlights the imperative for additional research for guideline adjustments and provides the opportunity for early intervention.
RESUMO
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. Descriptive statistics for the cohort were calculated for demographics, nutritional outcomes, and microbiology for the first year of life and lung function and growth outcomes were summarized for ages 6-10 years. RESULTS: From 2010 to 2020, there were 8765 children with diagnosis of CF or CRMS entered into the CFFPR with sufficient diagnostic data for classification, of which 7591 children had a clinical diagnosis of CF and 1174 had a clinical diagnosis of CRMS. CRMS patients exhibited normal nutritional indices and pulmonary function up to age 9-10 years. The presence of respiratory bacteria associated with CF, such as Pseudomonas aeruginosa from CRMS patients ranged from 2.1% to 9.1% after the first year of life. CONCLUSIONS: Children with CRMS demonstrate normal pulmonary and nutritional outcomes into school age. However, a small percentage of children continue to culture CF-associated respiratory pathogens after infancy.

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 LCI2.5 in detecting change after commencing ETI in the real world. PATIENT SELECTION/METHODS: Baseline anthropometric data were collected along with spirometry (forced expiratory volume in 1 s [FEV1], forced vital capacityFV and LCI2.5 measures in children aged 6-11 years with CF before starting ETI. Measures were repeated after a mean (range) of 8.2 (7-14) months of ETI treatment. The primary endpoint was a change in LCI2.5, with secondary endpoints including change in FEV1 and change in body mass index (BMI) also reported. RESULTS: Twelve children were studied (seven male, mean age 9.5 years at baseline). Our study population had a mean (SD) LCI2.5 of 7.01 (1.14) and FEV1 of 96 (13) %predicted at baseline. Mean (95% confidence interval) changes in LCI2.5 [-0.7 (-1.4, 0), p = .06] and BMI [+0.7 (+0.1, +1.3), p = .03] were observed, along with changes in FEV1 of +3.1 (-1.9, +8.1) %predicted. CONCLUSIONS: Real-world changes in LCI2.5 (-0.7) are different to those reported in clinical trials (-2.29). Lower baseline LCI2.5 as a result of prior modulator exposure, high baseline lung health, and new LCI2.5 software analyses all contribute to lower LCI2.5 values being recorded in the real world of children with CF.

Background and Objective: As life expectancy in cystic fibrosis (CF) has increased over the years, a shift in focus toward extra-pulmonary comorbidities such as gastrointestinal (GI) disease has become a topic of particular importance. Although not well-defined in the current literature, GI dysmotility is thought to significantly contribute to GI symptomatology in the CF population. The objective of this article was to provide a comprehensive review of diagnostic modalities at the disposal of the clinician in the evaluation of patients with CF (pwCF) presenting with GI complaints. Furthermore, we aimed to highlight the available literature regarding utilization of these modalities in CF, in addition to their shortcomings, and emphasize areas within the motility literature where further research is essential. Methods: A comprehensive review of all available literature in the English language through December 1, 2022 utilizing PubMed was conducted. Our search was limited to GI motility/transit and dysmotility in pwCF. Two researchers independently screened references for applicable articles and extracted pertinent data. Key Content and Findings: Several diagnostic imaging and manometry options exist in the evaluation of dysmotility; however, the literature is lacking in high-quality, prospective studies to validate such testing in pwCF. Common symptoms experienced and diagnostic motility tools available based on segment of the GI tract as related to pwCF are explored in the current review. Shortcomings in the current literature are identified and future direction to enhance research efforts within the field of CF-related dysmotility is provided. Conclusions: The influence of CF on GI integrity and motility is far-reaching. Despite improvements in longevity and advancement of pulmonary-specific treatment strategies, further high-quality research targeting the evaluation and management of GI dysmotility in pwCF is needed.
RESUMO
Given extensive pertinent disease factors and evolving medical treatments, this systematic review explores qualitative and quantitative cystic fibrosis (CF) research surrounding self-concept, an overarching perception of self. Research methodologies, self-concept dimensions, prominent self-concept findings and clinical recommendations are identified. Preferred Reporting Items for Systematic Review and Meta-analyses guidelines were applied. PubMed, Scopus, Medline, Psycinfo, CINAHL (ebsco), and CENTRAL Cochrane electronic databases were searched from 2012 to 2022. Methodological quality was assessed using the critical appraisal skills program. Data-based convergent synthesis was applied to analyze and report on qualitative and quantitative studies in parallel. Thirty-seven publications met the inclusion criteria, most of which employed a cross-sectional, single-center design within an adolescent and adult population. Self-efficacy, self-esteem, and self-identity studies were dimensions of self-concept identified, with studies relating to self-efficacy surrounding physical health management most prevalent. All three dimensions were positively associated with improved treatment adherence and psychosocial health. Efficacy tested intervention programs to enhance self-concept are limited; however, an extensive range of clinical recommendations are offered, highlighting the importance of clinician self-concept awareness, quality clinician-patient conversations and online CF peer-support. Self-concept is an important mechanism to optimize patient outcomes. Further CF self-concept research is required, particularly multicenter, longitudinal, and interventional studies. Early childhood, post lung transplant and the older adult CF population in particular, lack research attention. Given the potential impact of rapidly evolving CF transmembrane conductance regulator modulator drugs on many aspects of self, future self-concept research beyond the dimension of self-efficacy may be beneficial.

BACKGROUND: Nutritional challenges are common in early CF care and stressful for caregivers of children with CF (cwCF) to navigate. Gastrostomy tube (G-tube) placement can improve weight gain, however the decision to proceed with placement is personalized and preference-sensitive. Little is known about the experiences of caregivers of cwCF and the G-tube decision-making process. OBJECTIVES: The present study used a qualitative approach to explore the perceptions and experiences of caregivers of cwCF with G-tube introductions and recommendations, as well as factors influencing G-tube decision-making. METHODS: Caregivers of cwCF aged ≤ 10 years completed audio-taped, semi-structured interviews describing their experiences with G-tube placement discussions. Interviews were transcribed and two independent researchers coded the transcripts and conducted content and thematic analysis using an inductive approach. RESULTS: Participants included 43 caregivers, 84 % were mothers (36/43). CwCF had a mean age of 4 years (SD=2.6), 84 % were White (36/43), and 60 % reported weights below <50th percentile (26/43). All caregivers knew about G-tubes, 44 % (19/43) were recommended a G-tube and 35 % (15/43) had a G-tube placed. Major findings included descriptions of the stages of G-tube decision-making from a heads up, to the game plan, to making a first difficult decision and finally living with the decision to pursue G-tube placement. CONCLUSION: G-tube decision-making is an emotional and personalized journey for caregivers of cwCF. Efforts to explore the values and priorities of caregivers is imperative to supporting families making difficult decisions in CF care.
RESUMO
OBJECTIVE: This study was designed to assess obstructive sleep apnea (OSA) in adult patients with cystic fibrosis (CF) and non-CF bronchiectasis (BE) and to relate it with clinical characteristics. METHODS: Thirty-five CF (27 years) and 35 non-CF (24 years) BE patients were included. Demographic characteristics, medications, comorbidities, BMI, dyspnea scales, pulmonary functions, sputum cultures, exacerbations, and hospitalizations were recorded. The Epworth Sleepiness Scale (ESS) questionnaire was filled and polysomnography was performed for each patient. RESULTS: ESS scores did not show any significant difference between CF and non-CF BE patients. Thirty-seven (53%) of all patients had OSA. There was no significant difference in OSA risk between CF and non-CF BE patients (54% vs 51%, respectively). Male gender was found to be a risk factor for OSA (68% of males vs 41% of females, respectively, p:0.026). Total sleep time, sleep efficiency, sleep latency, time spent awake after falling asleep, oxygen desaturation index, apnea-hypopnea-index (AHI), AHI in the supine position, and rapid eye movement phase did not show any significant difference between CF and non-CF patients. CF patients had significantly lower mean oxygen saturation (p:0.001) and lowest oxygen saturation (p:0.0024) levels and higher heart rate (p:0.02) compared to non-CF BE patients. Multiple logistic regression analysis of all patients revealed male gender and disease duration as risk factors for OSA (p:0.023 and p:0.041 respectively). CONCLUSION: It is remarkable that more than half of the patients in both CF and non-CF bronchiectasis groups had OSA. Male gender and disease duration were found as risk factors for OSA.
