Unveiling the psychosocial impact of Elexacaftor/Tezacaftor/Ivacaftor therapy in Cystic Fibrosis patients
Background
This study aimed to assess how Elexacaftor/Tezacaftor/Ivacaftor (ETI) influences lung function, Body Mass Index (BMI), Sweat Test (ST) and mental health of Cystic Fibrosis (CF) patients, emphasizing on depression and anxiety.
Methods
We conducted an observational, prospective, multicentre study including 108 patients over 18 years old who initiated ETI therapy between December 2019 and December 2023. Patients underwent regular evaluations, including clinical, functional, and microbiological assessments, alongside completion of quality of life, anxiety, and depression questionnaires. We evaluated whether there was a difference in anxiety and depression levels over time.
Results
After 12 months of treatment, significant improvements were noted in BMI, lung function (FEV1%), ST and various aspects of quality of life (CFQ-R). However, anxiety and depression levels did not differ significantly during the follow-up. When we stratified our sample by key groups, we observed that younger patients (under 28 years) and those with homozygous Phe508del mutations experienced significant higher anxiety with no differences on depression. Furthermore, anxiety and depression demonstrated a moderate correlation, strengthening over time.
Conclusions
Treatment with ETI establishes significant improvements in lung function, BMI, ST and quality of life in patients with CF. However, despite these positive outcomes, there were no significant changes observed in levels of anxiety and depression, except for individuals with homozygous mutation type and those younger than 28 years old, who exhibited significant higher levels of anxiety.
