Öğe CFTR mutations unidentified in CFTR2 database and their phenotypic characteristics: Data from cystic fibrosis registry of Turkey(European Respiratory Soc Journals Ltd, 2020) Cinel, Guzin; Dogru, Deniz; Cakir, Erkan; Eyuboglu, Tugba Sismanlar; Cobanoglu, Nazan; Pekcan, Sevgi; Yalcin, Ebru[Abstract Not Availabe]Öğe Childhood interstitial lung disease in Turkey: first data from the national registry(Springer, 2023) Nayir-Buyuksahin, Halime; Emiralioglu, Nagehan; Kilinc, Ayse Ayzit; Girit, Saniye; Yalcin, Ebru; Eyuboglu, Tugba Sismanlar; Cobanoglu, NazanThe childhood interstitial lung diseases (chILD) Turkey registry (chILD-TR) was established in November 2021 to increase awareness of disease, and in collaboration with the centers to improve the diagnostic and treatment standards. Here, the first results of the chILD registry system were presented. In this prospective cohort study, data were collected using a data-entry software system. The demographic characteristics, clinical, laboratory, radiologic findings, diagnoses, and treatment characteristics of the patients were evaluated. Clinical characteristics were compared between two main chILD groups ((A) diffuse parenchymal lung diseases (DPLD) disorders manifesting primarily in infancy [group1] and (B) DPLD disorders occurring at all ages [group 2]). There were 416 patients registered from 19 centers. Forty-six patients were excluded due to missing information. The median age of diagnosis of the patients was 6.05 (1.3-11.6) years. Across the study population (n = 370), 81 (21.8%) were in group 1, and 289 (78.1%) were in group 2. The median weight z-score was significantly lower in group 1 (- 2.0 [- 3.36 to - 0.81]) than in group 2 (- 0.80 [- 1.7 to 0.20]) (p < 0.001). When we compared the groups according to chest CT findings, ground-glass opacities were significantly more common in group 1, and nodular opacities, bronchiectasis, mosaic perfusion, and mediastinal lymphadenopathy were significantly more common in group 2. Out of the overall study population, 67.8% were undergoing some form of treatment. The use of oral steroids was significantly higher in group 2 than in group 1 (40.6% vs. 23.3%, respectively; p = 0.040).Conclusion: This study showed that national registry allowed to obtain information about the frequency, types, and treatment methods of chILD in Turkey and helped to see the difficulties in the diagnosis and management of these patients.Öğe Clinical features and accompanying findings of Pseudo-Bartter Syndrome in cystic fibrosis(Wiley, 2020) Sismanlar Eyuboglu, Tugba; Dogru, Deniz; Cakir, Erkan; Cobanoglu, Nazan; Pekcan, Sevgi; Cinel, Guzin; Yalcin, EbruBackground Pseudo-Bartter syndrome (PBS) is a rare complication of cystic fibrosis (CF) and there are limited data in the literature about it. We aimed to compare clinical features and accompanying findings of patients with PBS in a large patient population. Methods The data were collected from the Cystic Fibrosis Registry of Turkey where 1170 CF patients were recorded in 2017. Clinical features, diagnostic test results, colonization status, complications, and genetic test results were compared in patients with and without PBS. Results Totally 1170 patients were recorded into the registry in 2017 and 120 (10%) of them had PBS. The mean age of diagnosis and current age of patients were significantly younger and newborn screening positivity was lower in patients with PBS (P < .001). There were no differences between the groups in terms of colonization status, mean z-scores of weight, height, BMI, and mean FEV1 percentage. Types of genetic mutations did not differ between the two groups. Accompanying complications were more frequent in patients without PBS. Conclusion PBS was detected as the most common complication in the registry. It could be due to warm weather conditions of our country. It is usually seen in younger ages regardless of mutation phenotype and it could be a clue for early diagnosis of CF.Öğe Cystic fibrosis in Turkey: First data from the national registry(Wiley, 2020) Dogru, Deniz; Cakir, Erkan; Sismanlar, Tugba; Cobanoglu, Nazan; Pekcan, Sevgi; Cinel, Guzin; Yalcin, EbruBackground Cystic fibrosis (CF) care has been implemented in Turkey for a long time; however, there had been no patient registry. For this purpose, the Turkish National CF Registry was established. We present the first results of registry using data collected in 2017. Methods The data were collected using a data-entry software system, which was accessed from the internet. Demographic and annually recorded data consisted of 15 and 79 variables, respectively. Results There were 1170 patients registered from 23 centers; the estimated coverage rate was 30%. The median age at diagnosis was 1.7 years (median current age: 7.3 years); 51 (4.6%) patients were aged over 18 years. Among 293 patients who were under 3 years of age, 240 patients (81.9%) were diagnosed through newborn screening. Meconium ileus was detected in 65 (5.5%) patients. Genotyping was performed in 978 (87.4%) patients and 246 (25.2%) patients' mutations were unidentified. The most common mutation was deltaF508 with an allelic frequency of 28%, followed by N1303K (4.9%). The median FEV1% predicted was 86. Chronic colonization with Pseudomonas aeruginosa was seen in 245 patients. The most common complication was pseudo-Bartter syndrome in 120 patients. The median age of death was 13.5 years in a total of 15 patients. Conclusions Low coverage rate, lack of genotyping, unidentified mutations, and missing data of lung functions are some of our greatest challenges. Including data of all centers and reducing missing data will provide more accurate data and help to improve the CF care in Turkey in the future.Öğe Cystic Fibrosis Patients Eligible for Modulator Drugs: Data from Cystic Fibrosis Registry of Turkey(European Respiratory Soc Journals Ltd, 2019) Cobanoglu, Fatma Nazan; Ersoz, Deniz Dogru; Cakir, Erkan; Eyuboglu, Tugba Sismanlar; Pekcan, Sevgi; Cinel, Guzin; Yalcin, Ebru[Abstract Not Availabe]Öğe Evaluation of respiratory function at 6 years of age in patients with cystic fibrosis with frequent pulmonary exacerbations in the first 2 years of life(European Respiratory Soc Journals Ltd, 2023) Tabakci, Sati Ozkan; Cinel, Guzin; Uytun, Salih; Polat, Sanem Eryilmaz; Yalcin, Ebru; Kiper, Nural; Erdal, Meltem Akgul[Abstract Not Availabe]Öğe Patients eligible for modulator drugs: Data from cystic fibrosis registry of Turkey(Wiley, 2020) Cobanoglu, Nazan; Ozcelik, Ugur; Cakir, Erkan; Eyuboglu, Tugba Sismanlar; Pekcan, Sevgi; Cinel, Guzin; Yalcin, EbruBackground 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.Öğe Patients with cystic fibrosis who could not receive the CFTR modulator treatment: What did they lose in 1 year?(Wiley, 2023) Uytun, Salih; Cinel, Guzin; Polat, Sanem Eryilmaz; Tabakci, Sati Ozkan; Kiper, Nural; Yalcin, Ebru; Tural, Dilber AdemhanBackgroundCystic 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. MethodsThis 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. ResultsIn 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. ConclusionsPatients 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.Öğe The success of the Cystic Fibrosis Registry of Turkey for improvement of patient care(Wiley, 2022) Asfuroglu, Pelin; Eyuboglu, Tugba Sismanlar; Aslan, Ayse Tana; Gursoy, Tugba Ramasli; Emiralioglu, Nagehan; Yalcin, Ebru; Kiper, NuralBackground Cystic fibrosis (CF) registries play an essential role in improving disease outcomes of people with CF. This study aimed to evaluate the association of newly established CF registry system in Turkey on follow-up, clinical, growth, treatment, and complications of people with this disease. Methods Age at diagnosis, current age, sex, z-scores of weight, height and body mass index (BMI), neonatal screening results, pulmonary function tests, history of meconium ileus, medications, presence of microorganisms, and follow-up were evaluated and compared to data of people with CF represented in both 2017 and 2019 registry data. Results There were 1170 people with CF in 2017 and 1637 in 2019 CF registry. Eight hundred and fourteen people were registered in both 2017 and 2019 of whom z-scores of heights and BMI were significantly higher in 2019 (p = 0.002, p =0.039, respectively). Inhaled hypertonic saline, bronchodilator, and azithromycin usages were significantly higher in 2019 (p =0.001, p = 0.001, p = 0.003, respectively). The percent predicted of forced expiratory volume in 1 sec and forced vital capacity were similar in 2017 and 2019 (88% and 89.5%, p = 0.248 and 84.5% and 87%, p =0.332, respectively). Liver diseases and osteoporosis were significantly higher, and pseudo-Bartter syndrome (PBS) was significantly lower in 2019 (p = 0.011, p = 0.001, p = 0.001, respectively). Conclusions The z-scores of height and BMI were higher, the use of medications that protect and improve lung functions was higher and incidence of PBS was lower in 2019. It was predicted that registry system increased the care of people with CF regarding their follow-up. The widespread use of national CF registry system across the country may be beneficial for the follow-up of people with CF.
