Item Patients eligible for modulator drugs: Data from cystic fibrosis registry of Turkey(John Wiley and Sons Inc., 2020) Çobanoğlu N.; Özçelik U.; Çakır E.; Şişmanlar Eyüboğlu T.; Pekcan S.; Cinel G.; Yalçın E.; Kiper N.; Emiralioğlu N.; Şen V.; Şen H.S.; Ercan Ö.; Çokuğraş H.; Kılınç A.A.; Al Shadfan L.M.; Yazan H.; Altıntaş D.U.; Karagöz D.; Demir E.; Kartal Öztürk G.; Bingöl A.; Başaran A.E.; Sapan N.; Çekiç Ş.; Çelebioğlu E.; Aslan A.T.; Gürsoy T.R.; Tuğcu G.; Özdemir A.; Harmancı K.; Yıldırım G.K.; Köse M.; Hangül M.; Tamay Z.; Süleyman A.; Yüksel H.; Yılmaz Ö.; Özcan G.; Topal E.; Can D.; Korkmaz Ekren P.; Çaltepe G.; Kılıç M.; Özdoğan Ş.; Doğru D.Background: A better understanding of cystic fibrosis transmembrane conductance regulator biology has led to the development of modulator drugs such as ivacaftor, lumacaftor-ivacaftor, tezacaftor-ivacaftor, and elexacaftor-tezacaftor-ivacaftor. This cross-sectional study evaluated cystic fibrosis (CF) patients eligible for modulator drugs. Methods: Data for age and genetic mutations from the Cystic Fibrosis Registry of Turkey collected in 2018 were used to find out the number of patients who are eligible for modulator therapy. Results: Of registered 1488 CF patients, genetic analysis was done for 1351. The numbers and percentages of patients and names of the drugs, that the patients are eligible for, are as follows: 122 (9.03%) for ivacaftor, 156 (11.54%) for lumacaftor-ivacaftor, 163 (11.23%) for tezacaftor-ivacaftor, and 57 (4.21%) for elexacaftor-tezacaftor-ivacaftor. Among 1351 genotyped patients total of 313 (23.16%) patients are eligible for currently licensed modulator therapies (55 patients were shared by ivacaftor and tezacaftor-ivacaftor, 108 patients were shared by lumacaftor-ivacaftor and tezacaftor-ivacaftor, and 22 patients were shared by tezacaftor-ivacaftor and elexacaftor-tezacaftor-ivacaftor groups). Conclusions: The present study shows that approximately one-fourth of the registered CF patients in Turkey are eligible for modulator drugs. As, frequent mutations that CF patients have in Turkey are different from North American and European CF patients, developing modulator drugs effective for those mutations is necessary. Furthermore, as modulator drugs are very expensive currently, financial support of the government in developing countries like Turkey is noteworthy. © 2020 Wiley Periodicals LLCItem Patients with cystic fibrosis who could not receive the CFTR modulator treatment: What did they lose in 1 year?(John Wiley and Sons Inc, 2023) Uytun S.; Cinel G.; Eryılmaz Polat S.; Özkan Tabakçı S.; Kiper N.; Yalçın E.; Ademhan Tural D.; Özsezen B.; Şen V.; Selimoğlu Şen H.; Ufuk Altıntaş D.; Çokuğraş H.; Kılınç A.A.; Başkan A.K.; Yazan H.; Çollak A.; Uzuner S.; Ünal G.; Yılmaz A.İ.; Çağlar H.T.; Damadoğlu E.; Irmak İ.; Demir E.; Kartal Öztürk G.; Bingöl A.; Başaran E.; Sapan N.; Canıtez Y.; Tana Aslan A.; Asfuroğlu P.; Harmancı K.; Köse M.; Hangül M.; Özdemir A.; Çobanoğlu N.; Özcan G.; Keskin Ö.; Yüksel H.; Özdoğan Ş.; Topal E.; Çaltepe G.; Can D.; Korkmaz Ekren P.; Kılıç M.; Emiralioğlu N.; Şişmanlar Eyüboğlu T.; Pekcan S.; Çakır E.; Özçelik U.; Doğru D.Background: Cystic fibrosis (CF) is an autosomal recessive disorder caused by CF transmembrane conductance regulator (CFTR) genetic variants. CFTR modulators improve pulmonary function and reduce respiratory infections in CF. This study investigated the clinical and laboratory follow-up parameters over 1 year in patients with CF who could not receive this treatment. Methods: This retrospective cohort study included 2018 and 2019 CF patient data from the CF registry of Turkey. Demographic and clinical characteristics of 294 patients were assessed, who had modulator treatment indications in 2018 but could not reach the treatment. Results: In 2019, patients younger than 18 years had significantly lower BMI z-scores than in 2018. During the 1-year follow-up, forced expiratory volumes (FEV1) and FEV1 z-scores a trend toward a decrease. In 2019, chronic Staphylococcus aureus colonization, inhaled antipseudomonal antibiotic use for more than 3 months, oral nutritional supplement requirements, and oxygen support need increased. Conclusions: Patients who had indications for modulator treatments but were unable to obtain them worsened even after a year of follow-up. This study emphasized the importance of using modulator treatments for patients with CF in our country, as well as in many countries worldwide. © 2023 Wiley Periodicals LLC.Item Comparison of clinical features of cystic fibrosis patients eligible but not on CFTR modulators to ineligible for CFTR modulators(John Wiley and Sons Inc, 2024) Nayır Büyükşahin H.; Emiralioğlu N.; Yalçın E.; Şen V.; Selimoğlu Şen H.; Arslan H.; Başkan A.K.; Çakır F.B.; Koray C.F.; Yılmaz A.İ.; Ercan F.; Altıntaş D.U.; Serbes M.; Keskin Ö.; Arık E.; Gülen F.; Barlık M.; Karcıoğlu O.; Damadoğlu E.; Köse M.; Ersoy A.; Bingöl A.; Başaran E.; Çakır E.P.; Aslan A.T.; Canıtez Y.; Korkmaz M.; Özdemir A.; Harmancı K.; Soydaş Ş.S.; Hangül M.; Yüksel H.; Özcan G.; Korkmaz P.; Kılıç M.; Gayretli Aydın Z.G.; Çaltepe G.; Can D.; Doğru S.; Kartal Öztürk G.; Süleyman A.; Topal E.; Özsezen B.; Hızal M.; Demirdöğen E.; Ogun H.; Börekçi Ş.; Yazan H.; Çakır E.; Şişmanlar Eyüboğlu T.; Çobanoğlu N.; Cinel G.; Pekcan S.; Özçelik U.; Doğru D.Introduction: Cystic fibrosis transmembrane conductance regulator (CFTR) modulator drugs target the underlying defect and improve CFTR function. They are a part of standard care in many countries, but not all patients are eligible for these drugs due to age and genotype. Here, we aimed to determine the characteristics of non-eligible patients for CFTR modulators in the CF registry of Turkey (CFRT) to highlight their clinical needs. Methods: This retrospective cohort study included CF patient data from the CFRT in 2021. The decision of eligibility for the CFTR modulator was determined according to the ‘Vertex treatment-Finder' on the Vertex® website. Demographic and clinical characteristics of patients were compared between eligible (group 1) and ineligible (group 2) groups for CFTR modulators. Results: Among the study population (N = 1527), 873 (57.2%) were in group 1 and 654 (42.8%) were in group 2. There was no statistical difference between groups regarding sex, meconium ileus history, diagnoses via newborn screening, FEV1 z-score, CF-associated complications, organ transplant history, and death. Patients in group 2 had a higher incidence of pancreatic insufficiency (87.7% vs. 83.2%, p =.010), lower median height z-scores (−0.87 vs. −0.55, p <.001), lower median body mass index z-scores (−0.65 vs. −0.50, p <.001), longer days receiving antibiotics due to pulmonary exacerbation (0 [interquartile range, IQR: 0–2] vs. 0 [IQR: 0–7], p = 0.001), and more non-invasive ventilation support (2.6% vs. 0.9%, p = 0.008) than patients in group 1. Conclusion: The ineligible group had worse clinical outcomes than the eligible group. This highlights their need for life-changing drugs to improve clinical outcomes. © 2024 Wiley Periodicals LLC.
