RESUMO
BACKGROUND: Cystic fibrosis (CF) is a severe hereditary disease with a multisystem lesion. Manifestations of CF include severe infectious purulent lesions of all parts of the respiratory tract, including purulent rhinosinusitis with nasal polyps. The involvement of the sinonasal region and the need for systemic use of ototoxic drugs (primarily aminoglycosides to treat resistant bacterial infection) potentially create a risk of both conductive and sensorineural hearing loss (SNHL). The available data on the epidemiology of hearing disorders in CF is contradictory. Currently, genetic determinants of the development of aminoglycoside SNHL have been identified. MATERIAL AND METHODS: For 136 CF patients (75 girls, 61 boys) aged 3 to 17 (9.4±3.9) years were performed audiological examination: tympanometry, transient-evoked otoacoustic emission and the pure tone threshold audiometry (standard frequency range) (n=126). History of systemic therapy with aminoglycosides was evaluated for each patient. Sequencing of c.35delG mutations in the GJB2 gene (nuclear DNA) and A1555G in the 12S rRNA gene (mitochondrial DNA) was performed in 215 patients with cystic fibrosis (the group partially overlaps with the audiological group), and as a control - 106 children with bronchial asthma and 103 healthy children, their age ranged from 3 to 17 (8.8±3.8) years. RESULTS: Audiological examination of CF children reveled a prevalence of conductive hearing loss comparable to the general population (2.4%). The frequency of SNHL was 1.6%, wich exceeds that of non-CF children. A genetic study revealed one case of heterozygous carriage of the c.35delG mutation in the GJB2 gene in a patient with bronchial asthma. In the group of patients with CF (n=215), mutations in the connexin 26 gene were not detected. No A1555G mutation was detected either in the group of patients with CF or in the control groups. CONCLUSIONS: Children with CF are at risk for the development of sensorineural, but not conductive hearing loss. Routine total screening for A1555G and c.35delG mutations probably seems not to be recommended.

BACKGROUND: Cost of illness studies are important tools to summarise the burden of disease for individuals, the healthcare system and society. The lack of standardised methods for reporting costs for cystic fibrosis (CF) makes it difficult to quantify the total socioeconomic burden. In this study, we aimed to comprehensively report the socioeconomic burden of CF in Canada. METHODS: The total cost of CF in Canada was calculated by triangulating information from three sources (Canadian CF Registry, customised Burden of Disease survey and publicly available information). A prevalence-based, bottom-up, human capital approach was applied, and costs were categorised into four perspectives (ie, healthcare system, individual/caregiver, variable (ie, medicines) and society) and three domains (ie, direct, indirect and intangible). All costs were converted into 2021 Canadian dollars (CAD) and adjusted for inflation. The cost of cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies was excluded. RESULTS: The total socioeconomic burden of CF in Canada in 2021 across the four perspectives was $C414 million. Direct costs accounted for two-thirds of the total costs, with medications comprising half of all direct costs. Out-of-pocket costs to individuals and caregivers represented 18.7% of all direct costs. Indirect costs representing absenteeism accounted for one-third of the total cost. CONCLUSION: This comprehensive cost of illness study for CF represents a community-oriented approach describing the socioeconomic burden of living with CF and serves as a benchmark for future studies.

OBJECTIVE: The pregnancy, delivery, and neonatal outcomes of pregnancies complicated by cystic fibrosis (CF) have yet to be evaluated in a prolonged, population-based study. We sought to evaluate the obstetric and neonatal outcomes in pregnant patients with CF using a national population database. STUDY DESIGN: Retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). All women who delivered or had a maternal death in the US (2004-2014) were included in the study. Pregnancy, delivery, and neonatal outcomes were compared between women with an ICD-9 diagnosis of cystic fibrosis to those without. RESULTS: Overall, 9 096 159 women met the inclusion criteria. Of these, 629 women (6.9/100000) had CF. Women with CF were more likely to be younger and have pregestational diabetes mellitus compared to those without. CF in pregnancy was associated with an increased risk of developing gestational diabetes mellitus [aOR 3.20 (95 %CI 2.48-4.15), p = 0.0001], placenta previa [aOR 2.74 (95 %CI 1.30-5.79), p = 0.008], preterm delivery [aOR 2.17 (95 %CI 1.71-2.77), p = 0.0001], operative vaginal delivery [aOR 1.59 (95 %CI 1.17-2.16), p = 0.003], and death [aOR 86.41 (95 %CI 30.91-241.58), p = 0.0001], and a decreased likelihood of having a spontaneous vaginal delivery [aOR 0.80 (95 %CI 0.66-0.97), p = 0.02]. Patients with CF were more likely to experience deep venous thrombosis [aOR 7.64 (95 %CI 1.90-30.72), p = 0.004] and disseminated intravascular coagulation [aOR 3.68 (95 %CI 1.37-9.87), p = 0.01] compared to those without. The risk of delivering a fetus with congenital anomalies was similar between groups. CONCLUSION: Pregnant patients with CF have an increased risk of developing adverse maternal and delivery outcomes. As such, these patients should receive vigilant surveillance during pregnancy.

INTRODUCTION: Chest-physiotherapy is a key element in treatment of cystic fibrosis and patient adherence is a major issue in global cystic fibrosis care. This study aims to assess adherence to chest physiotherapy in adults with cystic fibrosis who not treated with tritherapy and to analyze the impact of certain factors on adherence. METHODS: Thus is a cross-sectional study, conducted using a questionnaire and a physiotherapy evaluation. Adherence to this treatment was measured in terms of quantitative and qualitative aspects. The impact on adherence of 15 factors was then assessed. RESULTS: Only 47% of patients could be considered as adherent, with a significant disparity between a quantitative and qualitative assessment. Gender, working time, pathology severity, the fact of being regularly followed by a physiotherapist, the perceived benefit of the sessions and their replacement by physical activity, seem associated with adherence to this treatment. CONCLUSIONS: Taking into account the qualitative aspect of the sessions, our study reveals a low rate, in our cohort, of adherence to respiratory physiotherapy, and highlights six factors likely to predominate. Regular follow-up by a physiotherapist seems to be a determining factor in adherence to this treatment.

Cystic fibrosis (CF) is a life-threatening monogenic disease affecting thousands of people worldwide. Cystic fibrosis transmembrane conductance regulator (CFTR) is an ion channel that facilitates transportation of water and salts across epithelial cell membranes through the conductance of Cl- and other anions. A dysfunctional CFTR due to abnormalities in the cftr gene causes CF, which is believed to be a rare disease in India mainly due to mis/underdiagnosis. Although numerous diagnostic methods and treatment options are available for CF globally, most of these are unaffordable for developing countries like India. Currently, CF symptoms are managed with mucolytics, antibiotics, anti-inflammatory drugs, and various CFTR modulators based on the type of defect. While a definitive cure for CF remains elusive, advancements in stem cell and gene therapies hold promise for permanent cure in the near future. In this review, we discuss the prevalence of CF cases in India, affordable diagnostic methods, and treatment options amenable for developing countries. We further emphasize the scope for the universal newborn screening programme.

OBJECTIVES: Periodontitis is a highly prevalent complication of diabetes. However, the association between cystic fibrosis-related diabetes (CFRD) and periodontitis has not yet been evaluated. The objective of this study was to assess if: 1) CFRD is associated with periodontitis among adults with CF, and 2) periodontitis prevalence differs by CF and diabetes status. METHODS: This was a pilot cross-sectional study of the association between CFRD and periodontitis in adults with cystic fibrosis (CF) (N = 32). Historical non-CF controls (N = 57) from the U.S. National Health and Nutrition Examination Survey (NHANES) dataset were frequency matched to participants with CF on age, sex, diabetes status, and insulin use. We defined periodontitis using the U.S. Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) case definition, as the presence of two or more interproximal sites with CAL ≥3 mm and two or more interproximal sites with PD ≥4 mm (not on the same tooth) or one site with PD ≥5 mm. Because NHANES periodontal data were only available for adults ages ≥30 years, our analysis that included non-CF controls focused on this age group (CF N = 19, non-CF N = 57). Based on CF and diabetes status, we formed four groups: CFRD, CF and no diabetes, non-CF with diabetes, and non-CF and no diabetes (healthy). We used the Fisher's exact test for hypotheses testing. RESULTS: There was no association between CFRD and periodontitis for participants with CF ages 22-63 years (CFRD 67% vs. CF no diabetes 53%, P = 0.49), this was also true for those ages ≥30 years (CFRD 78% vs. CF no diabetes 60%, P = 0.63). For the two CF groups, the prevalence of periodontitis was significantly higher than for healthy controls (CFRD 78% vs. healthy 7%, P<0.001; CF no diabetes 60% vs. healthy 7%, P = 0.001) and not significantly different than the prevalence for non-CF controls with diabetes (CFRD 78% vs. non-CF with diabetes 56%, P = 0.43; CF no diabetes 60% vs. non-CF with diabetes 56%, P = 0.99). CONCLUSION: Among participants with CF, CFRD was not associated with periodontitis. However, regardless of diabetes status, participants with CF had increased prevalence of periodontitis compared to healthy controls.

BACKGROUND: Improved growth in children with CF may have resulted from advances in treatment for cystic fibrosis (CF) over the past two decades, including the implementation of newborn screening in Denmark in 2016. This observational cohort study focuses on changes in early growth in Danish children with CF born between 2000 and January 2022. METHODS: Age, length/height, and weight data of children 0-5 years old were obtained from the Danish CF Cohort. Data were stratified to four birth cohorts born between 2000 and 2022. Weight-for-age (WAZ), length-for-age (LAZ), height-for-age (HAZ) and body-mass-index (BMZ) z-scores were computed using WHO growth curves. Cubic spline mixed effects models were used to evaluate growth over 5 years between birth cohorts. RESULTS: We included 255 children in the analyses. Cubic spline mixed effects models show that catch-up growth improved in birth cohorts over time, with the 2016-2022 birth cohort achieving growth reference curve values in WAZ, LAZ/HAZ and BMZ the earliest. The proportion of underweight and stunting observations among children born 2000-2004 decreased by the 2016-2022 birth cohort, while the proportion of overweight, low BMZ and high BMZ observations increased. CONCLUSION: Advances in care for young children with CF have led to improvements in growth - with the 2016-2022 birth cohort approaching potential for overweight. Nonetheless, low BMZ remains. Immediate, individualized nutrition care throughout early childhood remain crucial in mitigating malnutrition.

OBJECTIVES: To analyze the evolution of clinical and anthropometric characteristics of children and adolescents with cystic fibrosis (CF) over 24 months, including the period of the COVID-19 pandemic. METHODS: A longitudinal study with data collection from May 2018 to November 2020 in physical and electronic records from a pediatric reference center, including individuals with CF aged up to 18 years. RESULTS: The sample encompassed 72 individuals. Weight (p < 0.01), height (p < 0.01), and body mass index (BMI) (p = 0.043) were higher in 2020 than in 2018. There were no significant changes in BMI-Z (p = 0.977) and in percentiles of weight (p = 0.540), height (p = 0.458), and BMI percentile (p = 0.454) between both periods. Pancreatic insufficiency was observed in 91.7% of patients in 2020, and there were twice as many confirmed cases of diabetes compared to 2018. There was a 9.7% increase in individuals colonized by the oxacillin-sensitive Staphylococcus aureus (OSSA) (p = 0.039) and an 11.1% reduction in non-colonized individuals (p = 0.008). CONCLUSION: Although there was an increase in weight, height, and BMI from 2018 to 2020, there were no significant changes in BMI-Z and in percentiles of weight, height, and BMI percentile, suggesting that the anthropometric aspects of nutritional status did not change in this period of 2 years. Moreover, there was an increase in the prevalence of individuals colonized by OSSA and a reduction in the prevalence of individuals non-colonized with any bacteria.

INTRODUCTION: Italian Cystic Fibrosis Registry (ICFR) collects data of patients with cystic fibrosis (CF) through the collaboration with Italian CF referral and support Centres (Italian law 548/93). It aims at analysing medium and long-term clinical and epidemiological trends, identifying healthcare needs at regional and national levels, contributing to healthcare programmes, and resource allocation. Italian data are also compared at international level through the collaboration with the European CF Registry for sharing epidemiological data on general aspects like CF epidemiology and specific topics such as the use of CFTR modulators. OBJECTIVES: The purpose of this Report is to provide updated demographic and clinical data of the Italian FC population for the years 2021 and 2022, to contribute essential information for the implementation of projects aimed at improving the management of patients affected by this disease. DESIGN: Analyses and results presented in this Report pertain to patients currently under care at Italian National Referral and Support Centres for Cystic Fibrosis and Paediatric Hospital 'Bambino Gesù' in the 2021-2022 period. Data were submitted by clinical Centres through a dedicated web-based software and underwent dual quality control (QC) measures: automated quantitative QC within the software and secondary QC at the European level before the integration into the European Cystic Fibrosis Registry. These measures ensure data completeness, accuracy, and longitudinal consistency with European core data. SETTING AND PARTICIPANTS: A total of 27 CF Centres, including referral and support centres, as well as 'Bambino Gesù' Children's Hospital CF centre, submitted their data to ICFR for the years 2021-2022. Althourgh CF Centres in Verona and Messina do not use the ICFR software, their data are centrally collected and subsequently forwarded to the European Registry. Data from service centres in Treviso and Rovereto are transmitted via the Verona CF Centre. Data from Sardinia Centre are currently unavailable. RESULTS: The results section provides a comprehensive overview of various aspects of CF epidemiology and patient characteristics. 1.Demography: in 2021 and 2022, 5,977 and 6,077 CF patients were respectively included in the ICFR, with median ages of 23.3 and 23.7 years. The prevalence rates were 10.1 and 10.3 per 100,000 residents in Italy for the respective years, with males comprising 51.6% on average. The distribution by age showed a higher frequency among patients aged 7 to 35 years; adult patients constituted 63.5% on average in both years. 2. Diagnosis: most CF patients were diagnosed before the age of two (mean value 57.9%), with a significant percentage diagnosed in adult age (35.4% in 2021 and 25.6% in 2022). 3.New diagnoses: there were 113 new diagnoses in 2021 and 121 in 2022, with estimated incidences of 1 in 9,097 living births in 2021 and 1 in 6,232 in 2022. 4. Genetics: genetic analyses were conducted on 99.9% of patients, revealing CFTR gene mutations in over 98% of cases. The F508del mutation was the most common (44% of alleles in 2021), with 18% of patients having at least one "residual function" mutation. Gating mutations were present in 3.4% of Italian patients, while 20% had at least one-stop codon mutation. 5.Lung function: lung function, measured by percent predicted (pp)FEV1 (Forced Expiratory Volume in the first second) progressively declined before adulthood, with the majority of paediatric patients (92.8% in 2021 and 93.8% in 2022) maintaining a ppFEV1≥70%. 6.Nutrition: critical periods for nutrition were identified as the first 6 months of life and adolescence, with higher prevalence of malnourished male adolescents compared to females. Suboptimal BMI values were more common in adult females (28.7% in 2021 and 26.9% in 2022) compared to males (14.2% in 2021 and 12.6% in 2022). 7. Complications: CF-related liver disease without cirrhosis was prevalent in patients under 18 years (21.9% in 2021 and 21.2 in 2022), while CF-related diabetes was most frequent in adults (24.2%). 8.Transplantation: over the two-year period, 28 patients underwent double-lung transplantation, with median ages of 29.1 in 2021 and 35.3 in 2022, respectively. Median waiting times ranged from 9.4 to 11.6 months. 9.Microbiology: chronic Pseudomonas aeruginosa infection affected 37.2% of adult patients in 2021 and 36.0% in 2022, compared to 7.4% and 6.5% in paediatric patients. Staphylococcus aureus infection rates were 34.6% and 42.2% in 2021 among adults and 34.4% and 36.7% in 2022 among paediatric patients. 10. Mortality: a total of 34 patients died during the 2021-22 period (19 females, 15 males), with median ages at death of 43.7 years in 2021 and 46 years in 2022 (excluding transplanted patients). CONCLUSIONS: The present Report is an update of the data published in the past years and summarizes the main epidemiological and clinical data regarding Italian CF subjects in the years 2021 and 2022. The number of patients registered in 2021 was 5,977, while in 2022 was 6,077. The population coverage estimates for 2022 to be around 97%. In 2020, 60.5% of patients were older than 18 years, in 2022 adult patients account for 63.5% of the Italian CF population. Over the years, therefore, an increase in the median age of Italian CF patients has been observed, reaching 23.7 years in 2022. The absolute number of new diagnoses per year remains substantially unchanged over the years (a total of 234 in the period under review). The median age at diagnosis in 2022 was 2.5 months, 62.6% of subjects are really diagnosed within the first year of life and almost 90% of them are diagnosed through neonatal screening. In 2022, almost all patients underwent genetic analysis (99.9%). Data collected confirm the great variability among Italian CF patients. As regards respiratory function, what is reported in previous reports is here confirmed, with an ever-increasing percentage of subjects under the age of 18 having normal respiratory function, moreover, less than 1% of paediatric patients has a severe lung function (ppFEV1<40). The marked improvement in this indicator in the adult population seems to be mainly due to the introduction from 2021 in Italy of therapy with highly effective CFTR modulators. At the same time, the close positive correlation between nutritional status and respiratory function is confirmed for the adult population. As regards chronic infection by Pseudomonas aeruginosa, in 2022, a reduction in the percentage of chronic infection is observed both among adults (36% vs 38.8% in 2020) and in paediatric patients (6.5% vs 7.6% in 2020). The most frequent complication in both paediatric and adult populations is liver disease (respectively, in 24.2% and 41.3% of subjects). In the two-year period, 34 patients died; their median age at death was between 43 and 46 years (transplant patients excluded); only two patients under the age of 18 died in the period 2021 and 2022, confirming once again that mortality in paediatric age is a rare event. The data presented in this Report shows how the register can be a national and international point of reference for CF patients and the scientific community, a tool for describing the Italian CF population over the years, and a starting point for planning epidemiological studies and clinical studies.

BACKGROUND: Sexual dysfunction (erectile dysfunction in males, sexual dissatisfaction, sexual interest/arousal disorders, and dyspareunia in females) has not been the subject of indepth research in people with cystic fibrosis (CF). This study aimed to determine the prevalence of sexual dysfunction in adults with CF, factors associated with sexual dysfunction, and the impact of sexual dysfunction on quality of life. METHOD: We conducted a multicentre study in adults with cystic fibrosis followed in specialist centres in Western France. We assessed erectile dysfunction and its severity using the IIEF5 self-questionnaire (International Index of Erectile Function); the FSFI (Female Sexual Function Index) was used to assess sexual function in females, and we evaluated quality of life in both sexes using the CFQ-R14+ questionnaire. RESULTS: In total, 77 males and 74 females completed the sexual function questionnaire (mean age 32+/- 10 and 25+/- 8,5 years respectively). Among them, 21 % of males and 30 % of females reported sexual dysfunction. CFQ-R14+ score was significantly lower in males with erectile dysfunction than those without (p < 0.001). Faecal incontinence was associated with more frequent sexual dysfunction in females and higher severity of erectile dysfunction in males. CONCLUSION: The prevalence of sexual disorders is relatively high in males and females with cystic fibrosis. Therefore, it seems important to train specialist teams to address the issue of sexuality without embarrassment, and to encourage them to seek out and treat faecal incontinence, which is associated with greater severity or frequency of these symptoms.

BACKGROUND: Cystic fibrosis (CF) is most common in populations of Northern European ancestry where the F508del variant predominates. In 2020, Iceland became a member of the European Cystic Fibrosis Society Patient Registry, and we launched an epidemiological study of CF in Iceland. The study aimed to determine the prevalence and the genetic variants present in the country. Furthermore, we aimed to describe the previous and the current situation regarding lung function, infections, complications, treatment, and follow-up to understand the strengths and weaknesses of CF care in Iceland. METHODS: This retrospective study included all individuals in Iceland with a confirmed CF diagnosis between 1955 and 2021. We conducted a medical records search for CF diagnosis codes and found 30 people with CF who were included in the study. Two hundred sixteen clinical variables were registered. A descriptive analysis of these was performed. RESULTS: The prevalence of CF in Iceland is 0.372:10,000 inhabitants. The F508del is the most common CF transmembrane conductance regulator (CFTR) variant (46.4%), closely followed by N1303K (44.6%). Staphylococcus aureus was the most common airway pathogen, followed by Pseudomonas aeruginosa. Nasal polyps and CF-related diabetes were the most common complications. Modern CF medications, including the recent CFTR modulators, are available. CONCLUSION: Even though Iceland has a relatively low prevalence of CF, it holds the highest known prevalence of the N1303K variant in Europe. Access to necessary treatment is satisfactory, but improvements are advisable for some aspects of the routine assessments by best practice guidelines.

BACKGROUND: Elexacaftor/tezacaftor/ivacaftor (ETI) has revolutionized cystic fibrosis (CF) treatment. However, previous research has demonstrated profound global disparities in diagnosis and treatment access. If unaddressed, these threaten to widen existing health inequities. Therefore, in this analysis we aimed to reappraise gaps and evaluate progress in diagnosis and treatment equity in high-income (HIC) versus low- and middle-income countries (LMICs). METHODS: Estimates of the global CF population were made in 158 countries using patient registries, systematic literature searches, and an international survey of 14 CF experts. Estimates of the global burden of undiagnosed CF were made using epidemiological studies identified in literature searches and registry coverage data. The proportion of people receiving ETI was estimated using publicly available revenue data and a survey of 23 national drug pricing databases. RESULTS: 188,336 (163,421-209,204) people are estimated to have CF in 96 countries. Of these, 111,767 (59%) were diagnosed and 51,322 (27%) received ETI. The undiagnosed patient burden is estimated to be 76,569 people, with 82% in LMICs. ETI is reimbursed in 35 HICs, but only one LMIC. Four years after approval, there are 13,723 people diagnosed with CF who live in a country where ETI is inaccessible. This increases to 76,199 when including the estimated undiagnosed population. CONCLUSIONS: Equitable access to CFTR modulators must become a top priority for the international CF community. ETI costs up to $322,000 per year but could be manufactured for $5000 to allow access under a voluntary license. Given the extent of disparities, other mechanisms to improve access that circumvent the manufacturer should also be considered.

BACKGROUND: Oral health impacts systemic health, individual well-being, and quality of life. It is important to identify conditions that may exacerbate oral disease to aid public health and policy development and promote targeted patient treatment strategies. Developmental defects can increase an individual's risk of dental caries, hypersensitivity, premature tooth wear, erosion, and poor aesthetics. As part of an ongoing study assessing oral health in adults with cystic fibrosis at Cork University Dental School and Hospital, a systematic review of available literature was conducted to assess the prevalence of enamel defects in people with cystic fibrosis. AIMS: To critically evaluate the literature to determine if the prevalence of developmental defects of enamel is higher in people with cystic fibrosis (PwCF). METHODS: Data Sources: Three online databases were searched Embase, Scopus, and Web of Science Core Collection. Studies that examined an association between cystic fibrosis and developmental defects of enamel were included in this systematic review. RESULTS: The initial search identified 116 publications from the following databases Embase, Web of Science Core Collection, and Scopus. Eleven studies were included for qualitative analysis. Nine studies concluded that PwCF had a higher prevalence of enamel defects than control people and one study found no difference in cystic fibrosis (CF) status. All studies had a risk of bias that may influence study results and their interpretation. CONCLUSIONS: The results of the systematic review show a consistent pattern that PwCF have a higher prevalence of DDE than people without CF. Genetic dysfunction, chronic systemic infections, and long-term antibiotic use are possible aetiological causes. This review highlights the need for future studies to investigate if DDEs are caused by the underlying CFTR mutation or as a consequence of disease manifestations and/or management.

The impact of evolving treatment regimens, airway clearance strategies, and antibiotic combinations on the incidence and prevalence of respiratory infection in cystic fibrosis (CF) in children and adolescents remains unclear. The incidence, prevalence, and prescription trends from 2002 to 2019 with 18,339 airway samples were analysed. Staphylococcus aureus [- 3.86% (95% CI - 5.28-2.43)] showed the largest annual decline in incidence, followed by Haemophilus influenzae [- 3.46% (95% CI - 4.95-1.96)] and Pseudomonas aeruginosa [- 2.80%95% CI (- 4.26-1.34)]. Non-tuberculous mycobacteria and Burkholderia cepacia showed a non-significant increase in incidence. A similar pattern of change in prevalence was observed. No change in trend was observed in infants < 2 years of age. The mean age of the first isolation of S. aureus (p < 0.001), P. aeruginosa (p < 0.001), H. influenza (p < 0.001), Serratia marcescens (p = 0.006) and Aspergillus fumigatus (p = 0.02) have increased. Nebulised amikacin (+ 3.09 ± 2.24 prescription/year, p = 0.003) and colistin (+ 1.95 ± 0.3 prescriptions/year, p = 0.032) were increasingly prescribed, while tobramycin (- 8.46 ± 4.7 prescriptions/year, p < 0.001) showed a decrease in prescription. Dornase alfa and hypertonic saline nebulisation prescription increased by 16.74 ± 4.1 prescriptions/year and 24 ± 4.6 prescriptions/year (p < 0.001). There is a shift in CF among respiratory pathogens and prescriptions which reflects the evolution of cystic fibrosis treatment strategies over time.

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.

It is estimated that in highly medicalised countries, median life expectancy for most newborns with cystic fibrosis now exceeds 70 years, approaching that of the general population. However, socio-economic disparities between countries continue to have a devastating impact on the prognosis of patients in Eastern Europe, Africa, India and South America. In Morocco, very limited genetic data suggest that the prevalence of this disease is at least of the same order as in Belgium. But as it is not really recognised by the national health system, patients are denied access even to symptomatic treatment. As a result, their outcome is tragic, similar to what it was 60 years ago in the most medicalised countries. A pilot project for a first paediatric reference centre in Casablanca is currently being set up. If properly resourced, this project can only be a success and should be the first step on the road towards cystic fibrosis care in this country. In a very humble way, several Belgian stakeholders are trying to support this project.
Dans les pays les plus médicalisés, l'espérance de vie médiane de la plupart des nouveau-nés atteints de mucoviscidose excède aujourd'hui 70 ans et se rapproche de celle de la population générale. Ailleurs, en Europe de l'Est comme en Afrique, en Inde ou en Amérique du Sud, les disparités socio-économiques des pays continuent à impacter très durement le pronostic des patients. Au Maroc, des données génétiques très fragmentaires suggèrent que la prévalence de la mucoviscidose est au moins du même ordre qu'en Belgique. Mais la maladie n'y est pas réellement reconnue par le système de santé, de telle sorte que même le traitement symptomatique reste inaccessible aux patients et leur pronostic est tragique, similaire à ce qu'il était il y a 60 ans dans les pays les plus médicalisés. À Casablanca, le projet pilote d'un premier Centre pédiatrique de Référence est en train de se mettre en place. S'il bénéficie d'un support adéquat, ce projet ne peut être qu'un succès et doit constituer un tout premier pas sur le chemin vers une prise en charge des patients dans ce pays. Très modestement, plusieurs intervenants belges tentent d'y apporter leur soutien.

BACKGROUND: Relieving gastrointestinal symptoms is a research priority in cystic fibrosis. Emerging evidence highlights effects of cystic fibrosis transmembrane conductance regulator (CFTR) modulators on gastrointestinal function, including pancreatic sufficiency. This study explores ivacaftor licensing and treatment on recorded pancreatic enzyme replacement therapy (PERT) prescription in the US and UK CF registries. METHODS: Retrospective longitudinal registry study of recorded pancreatic PERT use between 2008 and 2017. Interrupted time series analysis in propensity-matched cohorts estimated annual change and step change according to ivacaftor eligibility before and after licensing year, 2012. Generalised estimating equations assessed adjusted risk of PERT use in individuals treated with ivacaftor after 2012 compared to untreated individuals. RESULTS: In the US CF registry, the difference in annual change in prevalence of PERT use post-2012 between eligible cases and ineligible controls was -5.0 per 1000 people/year (95 %CI -7.6; -2.3, p = 0.001). The step change and annual change in prevalence of PERT use in eligible cases was not significantly different to controls in the UK CF registry. Relative to the relationship in 2013, ivacaftor treatment in the US CF registry was associated with a lower adjusted risk ratio of PERT use compared to untreated individuals by 2016 (0.97, 95 %CI 0.96; 0.99), which was not observed in the UK CF registry. CONCLUSIONS: Licensing of ivacaftor was followed by a lower prevalence of PERT use in the eligible US population compared to pre-licensing period, as well as lower risk of PERT use in those who received treatment. Inconsistencies in US and UK CF registries were observed.

BACKGROUND: Cystic fibrosis (CF) is a rare disease in Algeria, and its prognosis is poor in developing countries. The clinical and demographic knowledge of Algerian pediatric patients diagnosed with CF is incomplete due to the nonexistence of a national medical registry. Hence, the present study is the first Algerian multicentre study on CF. METHODS: This retrospective study was conducted in western Algeria. Over 1 year, the study included all pediatric patients with a confirmed diagnosis of CF in the pediatric hospital of Oran. Patient characteristics, clinical manifestations, and the prescribed treatment were reported. RESULTS: Thirty-four children (16 boys and 18 girls) participated in this study. Only 15 were diagnosed before the age of 6 months. The sweat chloride test was positive in all patients. Respiratory manifestations were found in all patients, chronic diarrhoea in 29 of them, and growth retardation in 10. Moreover, 25 (73.5%) had low to low intermediate socioeconomic levels. After diagnosis, respiratory complications marked the evolution of the 34 patients, with bronchial congestion observed in 33 of them, while 10 (29.4%) patients presented severe bronchopneumonia and 4 (11.8%) were affected by asthma. Consequently, three (8.8%) died at an average age of 9 years mainly because of respiratory failure. CONCLUSION: The prognosis of CF is poor in Algeria compared to other developed countries due to the longer diagnostic delay and limited therapeutic alternatives. This representative subset of Algerian pediatric patients with CF will serve as a reference for future studies on CF in Algeria.
