    BackgroundA collaboration between the University of Michigan (UM) Cystic Fibrosis Center (CFC) and Marmara University (MU) CFC was initiated in MU through conducting Quality Improvement projects (QIP). The global aim was to improve nutritional status of children with CF (cwCF), with a specific aim to increase the mean BMI percentile (BMIp) for cwCF by 10 percentile points in 12 months. MethodsBody mass index (BMI) percentiles of cwCF were categorized as: nutritionally adequate (BMIp >= 50%); at risk (BMIp 25%-49%); urgently at risk (BMIp 10%-25%); critically at risk (BMIp < 10%). Appropriate interventions were made according to BMIp category every three months. Forced expiratory volume in one-second percent predicted (FEV1pp), and health-related quality of life (HRQoL) were evaluated. ResultsOne hundred and eight-two cwCF with a mean age of 9.1 +/- 4.3 years were included in the project. Baseline BMIp increased from 25.6 to 37.2 at the 12th month (p < 0.001). In the critically at-risk group BMIp increased from 3.6 to 20.5 (p < 0.001), in the urgently at risk group from 15.9 to 30.8 (p < 0.001), in the at risk group from 37.0 to 44.2 (p < 0.079) and in the nutritionally adequate group the increase was from 66.8 to 69.5 (p < 0.301). FEV1pp also improved significantly, from 81.3 +/- 20.6 to 85.9 +/- 20.8 (p < 0.001). Physical functioning, eating problems, and respiratory symptoms domains of the HRQoL evaluation improved (p < 0.05). ConclusionThis project has led to significant improvements in BMIp, FEV1pp and HRQoL of cwCF; similar projects could easily be implemented by centers in other developing countries.

    (2023-03-01) ERGENEKON, ALMALA PINAR; YILMAZ YEĞİT, CANSU; SELÇUK, MERVE; KARABULUT, ŞEYDA; ÖZTÜRK THOMAS, GÜLTEN; ERDEM ERALP, ELA; ÜNVER, OLCAY; KARADAĞ, BÜLENT TANER; GÖKDEMİR, YASEMİN; ERGENEKON A. P., Gumus Z., YILMAZ YEĞİT C., Cenk M., Gulieva A., Kalyoncu M., SELÇUK M., KARABULUT Ş., ÖZTÜRK G., ERDEM ERALP E., et al.
    BackgroundThe aim of this study was to evaluate the prevalence of anxiety, depression, sleep, and associated factors in caregivers of children with spinal muscular atrophy (SMA). Materials and MethodsBeck Depression Inventory (BDI), the State-Trait Anxiety Inventory-State (STAI-S), the State-Trait Anxiety Inventory-Trait (STAI-T), and Pittsburgh Sleep Quality Index (PSQI) were used to assess the anxiety, depression, and sleep quality of the caregivers of children with SMA. Higher scores indicated worse outcome for all three questionnaires. ResultsFifty-six caregivers of children with SMA were included in the study. Median age of children was 6 (3.2-10) years and mean age of the caregivers was 37.0 +/- 6.5 years. Median scores of the BDI, STAI-S, STAI-T, and PSQI were 12 (7.2-17), 35.5 (31-44), 40.5 (35-48), and 7.0 (5.0-10.0), respectively. There was a positive correlation between BDI and PSQI scores (p < 0.05). There was a negative correlation between the age of the caregivers and PSQI, BDI, STAI-T scores (p = 0.01, r = -0.341; p = 0.006, r = -0.364; p = 0.003, r = -0.395, respectively). There was a negative correlation between the age of the patients and the PSQI scores of the caregivers (p = 0.01, r = -0.33). There was a negative correlation between BDI scores and household income (p = 0.01, r = -0.34). ConclusionCaregivers of children with SMA had elevated depression and anxiety levels and they also had decreased sleep quality. Economic and social support resources are needed to help caregivers of those children.

    Task Force report: European Respiratory Society statement for defining respiratory exacerbations in children and adolescents with bronchiectasis for clinical trials
    (2022-11-01) KARADAĞ, BÜLENT TANER; Chang A. B. , Zacharasiewicz A., Goyal V., Boyd J., Alexopoulou E., Aliberti S., Bell L., Bush A., Claydon A., Constant C., et al.
    Copyright © The authors 2022.Bronchiectasis is being diagnosed increasingly in children and adolescents. Recurrent respiratory exacerbations are common in children and adolescents with this chronic pulmonary disorder. Respiratory exacerbations are associated with an impaired quality-of-life, poorer long-term clinical outcomes and substantial costs to the family and health systems. The European Respiratory Society (ERS) clinical practice guideline for the management of children and adolescents with bronchiectasis provided a definition of acute respiratory exacerbations for clinical use but to date there is no comparable universal definition for clinical research. Given the importance of exacerbations in the field, this ERS task force sought to obtain robust definitions of respiratory exacerbations for clinical research. The panel was a multidisciplinary team of specialists in paediatric and adult respiratory medicine, infectious disease, physiotherapy, primary care, nursing, radiology, methodology, patient advocacy and parents of children and adolescents with bronchiectasis. We used a standardised process that included a systematic literature review, parents\" survey and a Delphi involving 299 physicians (54 countries) caring for children and adolescents with bronchiectasis. Consensus was obtained for all four statements drafted by the panel as the disagreement rate was very low (range 3.6% to 6.4%). The panel unanimously endorsed the four consensus definitions for: non-severe and severe exacerbations as an outcome measure; non-severe exacerbation for studies initiating treatment and; resolution of a non-severe exacerbation; for clinical trials involving children and adolescents with bronchiectasis. This ERS task force proposes using these internationally derived, consensus-based definitions of respiratory exacerbations for future clinical paediatric bronchiectasis research.

    Respiratory outcome of spinal muscular atrophy type 1 patients treated with nusinersen
    (2022-01-01) ERGENEKON, ALMALA PINAR; ÖZTÜRK THOMAS, GÜLTEN; ÜNVER, OLCAY; TÜRKDOĞAN, DİLŞAD; KARADAĞ, BÜLENT TANER; ERDEM ERALP, ELA; ERGENEKON A. P., YILMAZ YEĞİT C., Cenk M., GÖKDEMİR Y., ERDEM ERALP E., ÖZTÜRK G., ÜNVER O., Coskun O. K., Saygi E. K., TÜRKDOĞAN D., et al.
    Background Respiratory failure is the leading cause of mortality in spinal muscular atrophy type 1 (SMA1) children. The current study aims to evaluate the effect of nusinersen treatment on respiratory outcome of the patients with SMA1. Methods In this retrospective, single-center study, 52 SMA1 patients treated with nusinersen were included in the analysis. Patients were divided into two groups based on their age at the time of their first nusinersen treatment (Group 1: 6 months). Respiratory outcome on the 180th day of treatment is defined as the type of ventilation support (spontaneous breathing, noninvasive ventilation (NIV), and tracheostomized or intubated on invasive mechanical ventilation). Demographic data, respiratory outcome, and Children\"s Hospital of Philadelphia Infant Test of Neuromuscular Disorders scores were obtained from medical records. Results On the 180th day of treatment, 46 of the 52 (88.4%) children were alive. Prevalence of the mortality was similar in both groups (P = 0.65). The comparison of respiratory outcome in patients between group 1 and group 2 was as follows: spontaneous breathing, 7 (43.7%) versus 4 (13.3%) (P = 0.03); NIV = 16 h/day. There were significant improvements in Children\"s Hospital of Philadelphia Infant Test of Neuromuscular Disorders scores of the patients at day 180 in comparison with the baseline (P < 0.001). Conclusions Early initiation of nusinersen treatment in SMA1 patients may alter the disease\"s natural course.

    Lung function from school age to adulthood in primary ciliary dyskinesia
    (2022-10-01) KARADAĞ, BÜLENT TANER; Halbeisen F. S. , Pedersen E. S. , Goutaki M., Spycher B. D. , Amirav I., Boon M., Cohen-Cymberknoh M., Crowley S., EMİRALİOĞLU ORDUKAYA N., Haarman E. G. , et al.
    © 2022 European Respiratory Society. All rights reserved.Primary ciliary dyskinesia (PCD) presents with symptoms early in life and the disease course may be progressive, but longitudinal data on lung function are scarce. This multinational cohort study describes lung function trajectories in children, adolescents and young adults with PCD. We analysed data from 486 patients with repeated lung function measurements obtained between the age of 6 and 24 years from the International PCD Cohort and calculated z-scores for forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio using the Global Lung Function Initiative 2012 references. We described baseline lung function and change of lung function over time and described their associations with possible determinants in mixed-effects linear regression models. Overall, FEV1, FVC and FEV1/FVC z-scores declined over time (average crude annual FEV1 decline was −0.07 z-scores), but not at the same rate for all patients. FEV1 z-scores improved over time in 21% of patients, remained stable in 40% and declined in 39%. Low body mass index was associated with poor baseline lung function and with further decline. Results differed by country and ultrastructural defect, but we found no evidence of differences by sex, calendar year of diagnosis, age at diagnosis, diagnostic certainty or laterality defect. Our study shows that on average lung function in PCD declines throughout the entire period of lung growth, from childhood to young adult age, even among patients treated in specialised centres. It is essential to develop strategies to reverse this tendency and improve prognosis.

    Diffuse alveolar haemorrhage in children: an international multicentre study
    (2023-03-01) KARADAĞ, BÜLENT TANER; Ring A. M., Schwerk N., Kiper N., ASLAN A. T., Aurora P., Ayats R., Azevedo I., Bandeira T., Carlens J., Castillo-Corullon S., et al.
    Background Paediatric diffuse alveolar haemorrhage (DAH) is a rare heterogeneous condition with limited knowledge on clinical presentation, treatment and outcome. Methods A retrospective, descriptive multicentre follow-up study initiated from the European network for translational research in children’s and adult interstitial lung disease (Cost Action CA16125) and chILD-EU CRC (the European Research Collaboration for Children’s Interstitial Lung Disease). Inclusion criteria were DAH of any cause diagnosed before the age of 18 years. Results Data of 124 patients from 26 centres (15 counties) were submitted, of whom 117 patients fulfilled the inclusion criteria. Diagnoses were idiopathic pulmonary haemosiderosis (n=35), DAH associated with autoimmune features (n=20), systemic and collagen disorders (n=18), immuno-allergic conditions (n=10), other childhood interstitial lung diseases (chILD) (n=5), autoinflammatory diseases (n=3), DAH secondary to other conditions (n=21) and nonspecified DAH (n=5). Median (IQR) age at onset was 5 (2.0–12.9) years. Most frequent clinical presentations were anaemia (87%), haemoptysis (42%), dyspnoea (35%) and cough (32%). Respiratory symptoms were absent in 23%. The most frequent medical treatment was systemic corticosteroids (93%), hydroxychloroquine (35%) and azathioprine (27%). Overall mortality was 13%. Long-term data demonstrated persistent abnormal radiology and a limited improvement in lung function. Conclusions Paediatric DAH is highly heterogeneous regarding underlying causes and clinical presentation. The high mortality rate and number of patients with ongoing treatment years after onset of disease underline that DAH is a severe and often chronic condition. This large international study paves the way for further prospective clinical trials that will in the long term allow evidence-based treatment and follow-up recommendations to be determined.

    Development of core outcome measures sets for paediatric and adult severe asthma (COMSA)
    (2023-04-01) KARADAĞ, BÜLENT TANER; Khaleva E., Rattu A., Brightling C., Bush A., Bossios A., Bourdin A., Chung K. F., Chaudhuri R., Coleman C., Dahlén S., et al.
    Background Effectiveness studies with biological therapies for asthma lack standardised outcome measures. The COMSA (Core Outcome Measures sets for paediatric and adult Severe Asthma) Working Group sought to develop Core Outcome Measures (COM) sets to facilitate better synthesis of data and appraisal of biologics in paediatric and adult asthma clinical studies. Methods COMSA utilised a multi-stakeholder consensus process among patients with severe asthma, adult and paediatric clinicians, pharmaceutical representatives, and health regulators from across Europe. Evidence included a systematic review of development, validity and reliability of selected outcome measures plus a narrative review and a pan-European survey to better understand patients’ and carers’ views about outcome measures. It was discussed using a modified GRADE (Grading of Recommendations Assessment, Development and Evaluation) Evidence to Decision framework. Anonymous voting was conducted using predefined consensus criteria. Results Both adult and paediatric COM sets include forced expiratory volume in 1 s (FEV1) as z-scores, annual frequency of severe exacerbations and maintenance oral corticosteroid use. Additionally, the paediatric COM set includes the Paediatric Asthma Quality of Life Questionnaire and Asthma Control Test or Childhood Asthma Control Test, while the adult COM set includes the Severe Asthma Questionnaire and Asthma Control Questionnaire-6 (symptoms and rescue medication use reported separately). Conclusions This patient-centred collaboration has produced two COM sets for paediatric and adult severe asthma. It is expected that they will inform the methodology of future clinical trials, enhance comparability of efficacy and effectiveness of biological therapies, and help assess their socioeconomic value. COMSA will inform definitions of non-response and response to biological therapy for severe asthma.

    (2022-11-01) KARADAĞ SAYGI, NAİME EVRİM; KARADAĞ, BÜLENT TANER; DURMUŞ KOCAASLAN, FATMA NİHAL; TUTAR, ENGİN; Umay E., Eyigör S., Giray E., Saygi E. K., Karadağ B. T., Kocaaslan N. D., Yuksel D., Demir A. M., Tutar E., Tıkız C., et al.
    Background Currently, there is no comprehensive and multidisciplinary recommendation study covering all aspects of pediatric dysphagia (PD). This study aimed to generate PD management recommendations with methods that can be used in clinical practice to fill this gap in our country and in the world, from the perspective of experienced multidisciplinary experts. Methods This recommendation paper was generated by a multidisciplinary team, using the seven-step process and a three-round modified Delphi survey via e-mail. First, ten open-ended questions were created, and then detailed recommendations including management, diagnosis, treatment, and follow-up were created with the answers from these questions. Each recommendation item was voted on by the experts as overall consensus (strong recommendation), approaching consensus (weak recommendation) and divergent consensus (not recommended). Results In the 1st Delphi round, a questionnaire of 414 items was prepared based on the experts\" responses to ten open-ended questions. In the 2nd Delphi round, 59.2% of these items were accepted as pre-recommendation. In the 3rd Delphi round, 62.6% of 246 items were accepted for inclusion in the proposals. The final version recommendations consisted of 154 items. Conclusions This study includes comprehensive and detailed answers for every problem that could be posed in clinical practice for the management of PD, and recommendations are for all pediatric patients with both oropharyngeal and esophageal dysphagia.
