Purpose: Determining the frequency of M470V polymorphism in cystic fibrosis and healthy cohort in Tunisia to establish the contribution of M470V polymorphism in cystic fibrosis variable presentation and course. Additionally, studying the origin of cystic fibrosis transmembrane conductance regulator gene in Tunisian population and its evolution among populations worldwide.
Patients And Methods: The genotyping of M470V marker was realized by PCR-RFLP technique in 34 unrelated patients and 50 healthy subjects.
Results: Statistical difference was found in the genotype and allelic distribution between CF and control groups. Exclusive association between F508del allele and M470 allele was noted.
Conclusion: This study has contributed to better understanding involvement of the M470V polymorphism in the CF clinical expression in the Tunisian population and has confirmed the utility of this marker in the study of the origin and evolution of the CFTR locus in the human history.

Objectives: There is limited research on thyroid function in pediatric patients with cystic fibrosis (pwCF). This study aimed to determine the frequency of thyroid dysfunction in children and adolescents with CF and to evaluate iodine deficiency and selenium status in pwCF.
Methods: Sixty-two CF patients and 62 control subjects were evaluated.

Previous studies in sports science suggested that regular exercise has a positive impact on human health. However, the effects of endurance sports and their underlying mechanisms are still not completely understood. One of the main debates regards the modulation of immune dynamics in high-intensity exercise.

Background: Immediately after birth, adaptation to the extrauterine environment includes an upregulation of fatty acid catabolism. Cystic fibrosis and untreated hypothyroidism exert a life-long impact on fatty acid metabolism, but their influence during this transitional period is unknown. Children and adults with cystic fibrosis exhibit unbalanced fatty acid composition, most prominently a relative deficit of linoleic acid.

Background: The airways of patients with cystic fibrosis (pwCF) harbour complex fungal and bacterial microbiota involved in pulmonary exacerbations (PEx) and requiring antimicrobial treatment. Descriptive studies analysing bacterial and fungal microbiota concomitantly are scarce, especially using both culture and high-throughput-sequencing (HTS).
Objectives: We analysed bacterial-fungal microbiota and inter-kingdom correlations in two French CF centres according to clinical parameters and antimicrobial choices.

Background: Whether improvements in gastrointestinal (GI) symptoms observed with Elexacaftor/Tezacaftor/Ivacaftor (ETI) treatment are sustained in the longer-term requires exploration. This study investigated how GI-symptoms change with longer-term ETI use in pancreatic insufficient adults with cystic fibrosis (awCF).
Methods: Participants completed up to three abdominal symptom questionnaires, employing the validated CFAbd-Score.
