Abstract
Lung transplantation is considered as the ultimate therapy for children with advanced pulmonary disease. International data show a median conditional 1-year post-transplantation survival of 9.1 years. Recently, antibody-mediated rejection (AMR) has increasingly been recognized as an important cause of allograft dysfunction although pediatric reports are still scarce. Donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA) are known to play a role in AMR development post-transplant but AMR pathogenesis is still poorly understood. Central to the concept of pulmonary AMR is immune activation with the production of allo-specific B-cells and plasma cells directed against donor lung antigens. The frequency of pulmonary AMR in children is currently unknown. Due to the lack of AMR data in children, the diagnostic approach for pediatric pulmonary AMR is solely based on adult literature. This personal viewpoint article evaluates the rational for the creation of age-based thresholds for different diagnostic categories of pulmonary AMR and data on the management of pulmonary AMR in children. To the authors' knowledge, there have been no randomized controlled trials comparing different management regimes in pulmonary AMR, and thus, management and treatment algorithms for pulmonary AMR in children are only extrapolated from adults. To advance the knowledge of AMR in children, the authors propose that children be included in collaborative, multi-center trials. It is vital that future decisions on internationally agreed upon guidelines for pulmonary AMR take its impact on children into consideration. Research is needed to fill the current knowledge gaps in the field of pulmonary AMR in children focused on optimizing outcomes.

Abstract
Rationale: Cardiopulmonary exercise testing (CPET) provides prognostic information in cystic fibrosis (CF); however, its prognostic value for patients with advanced CF lung disease is unknown. Objectives: To determine the prognostic value of CPET on the risk of death or lung transplant (LTX) within 2 years. Methods: We retrospectively collected data from 20 CF centers in Asia, Australia, Europe, and North America on patients with a forced expiratory volume in 1 second (FEV1) ⩽ 40% predicted who performed a cycle ergometer CPET between January 2008 and December 2017. Time to death/LTX was analyzed using mixed Cox proportional hazards regression. Conditional inference trees were modeled to identify subgroups with increased risk of death/LTX. Results: In total, 174 patients (FEV1, 30.9% ± 5.8% predicted) were included. Forty-four patients (25.5%) died or underwent LTX. Cox regression analysis adjusted for age, sex, and FEV1 revealed percentage predicted peak oxygen uptake ([Formula: see text]o2peak) and peak work rate (Wpeak) as significant predictors of death/LTX: adjusted hazard ratios per each additional 10% predicted were 0.60 (95% confidence interval, 0.43-0.90; P = 0.008) and 0.60 (0.48-0.82; P < 0.001). Tree-structured regression models, including a set of 11 prognostic factors for survival, identified Wpeak to be most strongly associated with 2-year risk of death/LTX. Probability of death/LTX was 45.2% for those with a Wpeak ⩽ 49.2% predicted versus 10.9% for those with a Wpeak > 49.2% predicted (P < 0.001). Conclusions: CPET provides prognostic information in advanced CF lung disease, and Wpeak appears to be a promising marker for LTX referral and candidate selection.

Abstract
Pediatric lung transplantation (LTX) remains limited by the scarcity of small donor lungs, particularly in less populated parts of the world. Optimal organ allocation, including the prioritization and ranking of pediatric LTX candidates, and the appropriate matching of pediatric donors to recipients have been crucial elements in improving pediatric LTX outcomes. We aimed to elucidate the various pediatric lung allocation practices worldwide. A global survey of current pediatric solid organ transplantation deceased donation allocation practices was conducted by the International Pediatric Transplant Association (IPTA), and these policies were subsequently analyzed if publicly available, with focus on pediatric lung transplantation. Significant variation was found in lung allocation systems worldwide both in terms of prioritization and distribution for children. Definition of pediatrics varied from <12 years of age to <18 years of age. While several countries performing LTX for young children do not have a formal system to prioritize pediatric candidates, many countries that perform LTX at higher rates do offer prioritization methods for children: including the United States, United Kingdom, France, Italy, Australia, and countries serviced by Eurotransplant. Certain lung allocation practices for pediatrics are highlighted herein, including the newly instituted Composite Allocation Score (CAS) system in the United States, pediatric matching with Eurotransplant, and pediatric prioritization in Spain. The systems highlighted here explicitly aim to provide judicious and high quality LTX care for children.

Abstract
INTRODUCTION Chronic lung allograft dysfunction (CLAD) continues to negatively impact the survival of pediatric lung transplant (LTx) recipients. Current consensus guidelines are adult-focused. We sought to examine CLAD detection and monitoring practices at pediatric LTx programs. METHODS We conducted a survey among the International Pediatric Lung Transplant Collaborative. Questions consisted of practitioner's experience, LTx program demographics, and querying tests used for CLAD surveillance and detection. Investigations queried included: chest x-ray (CXR), chest computed tomography (CT), lung magnetic resonance imaging (MRI), ventilation/perfusion scanning, conventional pulmonary function testing (PFT), multiple breath washout (MBW), infant/preschool PFT, bronchoalveolar lavage, transbronchial biopsies (TBBx), or other tissue sampling techniques. Preferences for certain modalities over others were questioned based on a five-point Likert scale. RESULTS Twenty-four of 25 programs responded. Chest CT and CXR are used generally for both CLAD surveillance and detection. No programs use lung MRI clinically, it may have some utility in the future. While all centers use conventional PFT, MBW, and infant/preschool PFT are used in one-fifth and one-third of centers, respectively. While the majority of programs use TBBx, only 41.7% would obtain a diagnosis based on tissue histopathology over noninvasive techniques if CLAD is suspected. Utilization of biomarkers is still limited. CONCLUSIONS Our results indicate continued use of conventional PFT along with chest CT and less so CXR for CLAD detection and monitoring in the large majority of centers. Infant/preschool PFT and novel methods such as MBW are used in a few centers only. Respondents agreed there is a timely need for pediatric consensus guidelines on CLAD detection and monitoring.

Abstract
BACKGROUND COVID-19 vaccination has been successful in decreasing rates of SARS-CoV-2 infection in areas with high vaccine uptake. Cases of breakthrough SARS-CoV-2 infection remain infrequent among immunocompetent vaccine recipients who are protected from severe COVID-19. Robust data demonstrate the safety, immunogenicity, and effectiveness of several COVID-19 vaccine formulations. Importantly, Pfizer-BioNTech BNT162b2 mRNA COVID-19 vaccine studies have now included children as young as 5 years of age with safety, immunogenicity, and effectiveness data publicly available. In the United States, emergency use authorization by the Federal Drug Administration and approval from the Centers for Disease Control/Advisory Committee on Immunization Practices have been provided for the 5- to 11-year-old age group. METHODS Members of the International Pediatric Transplant Association (IPTA) provide an updated review of current COVID-19 vaccine data with focus on pediatric solid organ transplant (SOT)-specific issues. RESULTS This review provides an overview of current COVID-19 immunogenicity, safety, and efficacy data from key studies, with focus on data of importance to pediatric SOT recipients. Continued paucity of data in the setting of pediatric transplantation remains a challenge. CONCLUSIONS Further studies of COVID-19 vaccination in pediatric SOT recipients are needed to better understand post-vaccine COVID-19 T-cell and antibody kinetics and determine the optimal vaccine schedule. Increased COVID-19 vaccine acceptability, uptake, and worldwide availability are needed to limit the risk that COVID-19 poses to pediatric solid organ transplant recipients.

Abstract
Bronchiolitis obliterans syndrome (BOS) may develop after either lung or haematopoietic stem cell transplantation (HSCT), with similarities in histopathological features and clinical manifestations. However, there are differences in the contributory factors and clinical trajectories between the two conditions. BOS after HSCT occurs due to systemic graft-versus-host-disease (GVHD), whereas BOS after lung transplantation is limited to the lung allograft. BOS diagnosis after HSCT is more challenging, as the lung function decline may occur due to extrapulmonary GVHD, causing sclerosis or inflammation in the fascia or muscles of the respiratory girdle. Treatment is generally empirical with no established effective therapies. This review provides rare insights and commonalities of both conditions, that are not well elaborated elsewhere in contemporary literature, and highlights the importance of cross disciplinary learning from experts in other transplant modalities. Treatment algorithms for each condition are presented, based on the published literature and consensus clinical opinion. Immunosuppression should be optimised, and other conditions or contributory factors treated where possible. When initial treatment fails, the ultimate therapeutic option is lung transplantation (or re-transplantation in the case of BOS after lung transplantation) in carefully selected candidates. Novel therapies under investigation include aerosolised liposomal cyclosporine, Janus kinase inhibitors, antifibrotic therapies, and (in patients with BOS after lung transplantation) B-cell–directed therapies. Effective novel treatments that have a tangible impact on survival and thereby avoid the need for lung transplantation or re-transplantation are urgently required.

Abstract
There has been a shift over decades in the diagnostic indications for lung transplantation in children; in particular, there has been a reduction in the proportion of pediatric cystic fibrosis (CF) patients undergoing lung transplantation early in life, and more transplants occurring in other diagnostic groups. Here, we examine trends in pediatric lung transplantation with regards to indication by analyzing data from the United Network of Organ Sharing, the International Society for Heart and Lung Transplantation Thoracic Transplant Registry, and other sources. Over the past two years, there has been a precipitous decline in both the number of transplants due to CF and the proportion of CF cases relative to the total number of transplants, likely not solely due to the COVID-19 pandemic. In 2020, primary pulmonary arterial hypertension for the first time surpassed CF as main indication for pediatric lung transplantation in the United States, a finding that is also reflected in international data. We discuss the effect of novel CFTR modulator therapies as a major factor leading to this shifting landscape. Based on our trending, pulmonary hypertension-related diagnoses and pediatric interstitial lung diseases are rising indications, for which we suggest adjustments of consensus guidelines around candidate selection criteria.

Abstract
AIMS OF THE STUDY Organ donation after circulatory death (DCD) was reintroduced in Switzerland in 2011 and accounts for a third of deceased organ donors today. Controversy persists if DCD transplants are of similar quality to transplants following donation after brain death (DBD), mainly due to warm ischaemia time DCD organs are exposed to. We compared DCD with DBD in Switzerland. METHODS Data on deceased adults who were referred to and approved for organ donation from 1 September 2011 to 31 December 2019 were retrospectively analysed (217 DCD, 840 DBD donors). We compared DCD and DBD donor/organ characteristics, transplant rates of lungs, liver, kidneys, and pancreas, and early liver and kidney graft function in the recipient. The effect of DCD/DBD on transplant rates (organ transplanted or not) and 72-hour recipient graft function (moderate/good vs delayed graft function / organ loss) was analysed using multivariable logistic regression. Among utilised DCD donors, we analysed the effect of functional warm ischaemia time (FWIT) and donor age on 72-hour post-transplant liver and kidney graft function, also using multivariable logistic regression. RESULTS DCD donors were more often male (64.5% vs 56.8% p = 0.039), presented with heart disease (36.4% vs 25.5%, p <0.001), were resuscitated before hospital admission (41.9% vs 30.7%, p = 0.006), and died from anoxia (41.9% vs 23.9%). Kidney function before transplantation was comparable, lung, liver and pancreas function were poorer in DCD than DBD. Eighty-one and 91% of approved DCD and DBD donors were utilised (p <0.001). Median FWIT in DCD was 29 minutes (interquartile range 25-35). DCD transplant rates ranged from 4% (pancreas) to 73% (left kidney) and were all lower compared with DBD. Seventy-two-hour liver graft function was comparable between DCD and DBD (94.2% vs 96.6% moderate/good, p = 0.199). DCD kidney transplants showed increased risk of delayed graft function or early organ loss (odds ratios 8.32 and 5.05; 95% confidence intervals CI 5.28-13.28 and 3.22-7.95; both p <0.001, for left and right kidney transplants, respectively). No negative effect of prolonged FWIT or higher donor age was detected. CONCLUSION Despite less favourable donor/organ characteristics compared with donation after brain death, donation after circulatory death donors are increasingly referred and today provide an important source for scarce transplants in Switzerland. We identified a higher risk for delayed graft function or early organ loss for DCD kidney transplants, but not for DCD liver transplants. When carefully selected and allowed for other risk factors in organ allocation, prolonged functional warm ischaemia time or higher age in donation after circulatory death does not seem to be associated with impaired graft function early after transplantation.

Abstract
Cystic fibrosis (CF) is the most common autosomal recessive disorder in Caucasian people and is caused by mutations in the gene encoding for the CF transmembrane conductance regulator (CFTR) protein. It is a multisystem disorder; however, CF lung disease causes most of its morbidity and mortality. Although survival for CF has improved over time due to a multifaceted symptomatic management approach, CF remains a life-limiting disease. For individuals with progressive advanced CF lung disease (ACFLD), lung transplantation is considered the ultimate treatment option if compatible with goals of care. Since 2012, newer drugs, called CFTR modulators, have gradually become available, revolutionizing CF care, as these small-molecule drugs target the underlying defect in CF that causes decreased CFTR protein synthesis, function, or stability. Because of their extremely high efficacy and overall respectable tolerability, CFTR modulator drugs have already proven to have a substantial positive impact on the lives of individuals with CF. Individuals with ACFLD have generally been excluded from initial clinical trials. Now, however, these drugs are being used in clinical practice in selected individuals with ACFLD, showing promising results, although randomized controlled trial data for CFTR modulators in this subgroup of patients are lacking. Such data need to be gathered, ideally in randomized controlled trials including patients with ACFLD. Furthermore, the efficacy and tolerability of the newer modulator therapies in individuals with ACFLD need to be monitored, and their impact on lung disease progression and the need for lung transplantation as the ultimate therapy call for an objective evaluation in larger patient cohorts. As of today, guidelines for referral and listing of lung transplant candidates with CF have not incorporated the status of the new CFTR modulator therapies in the referral and listing process. The purpose of this review article, therefore, is threefold: first, to describe the effects of new therapies, with a focus on the subgroup of individuals with ACFLD; second, to provide an update on the recent outcomes after lung transplantation for individuals with CF; and third, to discuss the referral, evaluation, and timing for lung transplantation as the ultimate therapeutic option in view of the new treatments available in CF.

Abstract
BACKGROUND We have recently reported reduced physical activity (PA) in people with cystic fibrosis (pwCF) with and without lung transplantation (LTX) during a 6-week stringent lockdown in Switzerland. This follow-up study explores the impact of coronavirus-2019 disease (COVID-19) related pandemic restrictions on individuals' therapy regimens and health-related aspects in pwCF. METHODS We conducted a cross-sectional web-based national survey in Spring 2021. The survey included questions on daily PA, airway clearance and inhalation therapy, questions on COVID-19-compatible symptoms, diagnostic tests and vaccination status, and enquired health-related aspects covering the pandemic period between March 2020 to April 2021. RESULTS 193 individuals with CF (53% female; 25% LTX recipients) participated. Among pwCF, 10 reported COVID-19 (n = 2 LTX recipients), two subjects were hospitalized, no invasive ventilation required, no deaths. The clinical course was generally mild. Overall, 46% reported less PA during the pandemic, mostly due to closed fitness facilities (85%), lack of motivation (34%), and changes in daily structures (21%). In contrast, 32/193 (17%) pwCF were able to increase their PA levels: 12 (38%) and 11 (34%) reported undertaking home-based training and outdoor activities more frequently; 6 (19%) reported an increase in routine PA, and another 3 (9%) started new activities. Among pwCF without LTX, 5% and 4% reported to undertake less airway clearance and inhalation therapy, respectively. CONCLUSIONS Our study reveals unfavorable consequences of COVID-19 pandemic restrictions on PA of pwCF with unknown long-term consequences for their overall physical fitness and lung health. Strategies to overcome this undesirable situation are needed; increased uptake of telehealth PA programs and virtual exercise classes to promote PA participation might be one promising approach along with vaccination of pwCF and their close contacts.

Abstract
BACKGROUND Population-level COVID-19 immunization will play a key role in slowing down the SARS-CoV-2 pandemic on a global scale and protect the most at-risk individuals. Thanks to a formidable universal effort, several SARS-CoV-2 vaccines have been marketed less than a year since the first documented COVID-19 case, with promising safety, efficacy, and immunogenicity results in adults. As children were not included in the initial trials, no vaccine is currently approved for individuals <16 years of age. Similarly, immunosuppressed individuals, such as solid organ transplant recipients, were excluded from initial vaccine trials, limiting the understanding of vaccine immunogenicity and safety in this at-risk population. Thus, data regarding COVID-19 vaccination in pediatric solid organ transplantation recipients are currently lacking. METHODS Members of the International Pediatric Transplant Association review the current general status of COVID-19 vaccines focusing on pediatric-specific issues. RESULTS This review provides an overview of COVID-19 vaccines in pediatric SOT recipients and highlights the current paucity of data in both pediatric and transplant settings in terms of safety, immunogenicity, and clinical efficacy. CONCLUSIONS Vaccine trials including children and transplant recipients are underway and will be necessary to characterize COVID-19 vaccine safety, immunogenicity, and efficacy, which will determine potential future research directions.

Abstract
Chronic organ shortage remains the most limiting factor in lung transplantation. To overcome this shortage, a minority of centers have started with efforts to reintroduce donation after circulatory death (DCD). This review aims to evaluate the experimental background, the current international clinical experience, and the further potential and challenges of the different DCD categories. Successful strategies have been implemented to reduce the problems of warm ischemic time, thrombosis after circulatory arrest, and difficulties in organ assessment, which come with DCD donation. From the currently reported results, controlled-DCD lungs are an effective and safe method with good mid-term and even long-term survival outcomes comparable to donation after brain death (DBD). Primary graft dysfunction and onset of chronic allograft dysfunction seem also comparable. Thus, controlled-DCD lungs should be ceased to be treated as marginal and instead be promoted as an equivalent alternative to DBD. A wide implementation of controlled-DCD-lung donation would significantly decrease the mortality on the waiting list. Therefore, further efforts in establishment of legislation and logistics are crucial. With regard to uncontrolled DCD, more data are needed analyzing long-term outcomes. To help with the detailed assessment and improvement of uncontrolled or otherwise questionable grafts after retrieval, ex-vivo lung perfusion is promising.

Abstract
Solid organ transplant (SOT) recipients are exposed to respiratory viral infection (RVI) during seasonal epidemics; however, the associated burden of disease has not been fully characterized. We describe the epidemiology and outcomes of RVI in a cohort enrolling 3294 consecutive patients undergoing SOT from May 2008 to December 2015 in Switzerland. Patient and allograft outcomes, and RVI diagnosed during routine clinical practice were prospectively collected. Median follow-up was 3.4 years (interquartile range 1.61-5.56). Six hundred ninety-six RVIs were diagnosed in 151/334 (45%) lung and 265/2960 (9%) non-lung transplant recipients. Cumulative incidence was 60% (95% confidence interval [CI] 53%-69%) in lung and 12% (95% CI 11%-14%) in non-lung transplant recipients. RVI led to 17.9 (95% CI 15.7-20.5) hospital admissions per 1000 patient-years. Intensive care unit admission was required in 4% (27/691) of cases. Thirty-day all-cause case fatality rate was 0.9% (6/696). Using proportional hazard models we found that RVI (adjusted hazard ratio [aHR] 2.45; 95% CI 1.62-3.73), lower respiratory tract RVI (aHR 3.45; 95% CI 2.15-5.52), and influenza (aHR 3.57; 95% CI 1.75-7.26) were associated with graft failure or death. In this cohort of SOT recipients, RVI caused important morbidity and may affect long-term outcomes, underlying the need for improved preventive strategies.

Abstract
Although transplantation medicine is not new, there is a clinically justified gap in the existing literature with respect to the psychological processing of lung transplants. The present study aims to examine whether lung transplantation leads to an actualization of psychological, e.g., oral-sadistic fantasies. Following a qualitative approach, 38 lung transplant patients were interviewed three times within the first six months after transplantation. Data analysis focused on identifying unconscious and conscious material. The inter-rater reliability for all codes was calculated using Krippendorff’s Alpha (c-α-binary = 0.94). Direct and implicit evidence of a so-called transplantation complex was detected e.g., regarding the “incorporation” of the dead donor and his lungs. These processes occur predominantly at an imaginary level and are related to the body. Our findings emphasize that such psychological aspects should be borne in mind in the psychological treatment of lung-transplant patients in order to improve the processing of lung transplants, and that this might have a positive effect on patient adherence.

Abstract
Lung transplantation is a treatment option for selected children with end-stage lung disease and pulmonary vascular disorders. Overall, pulmonary hypertension (PH) is the second most frequent indication for infants and children requiring lung transplants. In pediatric PH patients, timing for listing remains a difficult decision due to patient heterogeneity and varying allocation policies across different countries. Furthermore, perioperative management can be challenging, making interdisciplinary collaboration among surgical, anesthesiology, critical care, and lung transplant teams essential. Because pediatric PH patients typically have preserved cardiac index and exercise tolerance even with advanced disease, they should be referred early even if they do not meet the criteria for listing of primarily adults by International Society for Heart and Lung Transplantation (ISHLT) published in 2015: New York Heart Association (NYHA) functional class III or IV without improvement, cardiac index < 2 L/min/m2 , mean right atrial pressure of >15 mmHg. Bridging strategies with extracorporeal support should be determined at the time of listing in anticipation of possible clinical deterioration. Bilateral lung transplantation using cardiopulmonary bypass to provide hemodynamic stability is nowadays the standard surgical approach in pediatric centers. The immediate post-transplant period is characterized by dramatic changes in the right ventricle (RV) and and left ventricle (LV) anatomy and physiology, which can be life-threatening. Induction, immunosuppression, prophylaxis, and surveillance are not different from patients without PH. Overall, outcomes in pediatric lung and heart-lung transplant patients for PH are not different from those children undergoing transplantation for other indications. In fact, long-term survival is superior in children with idiopathic PH compared to other diseases, providing most recipients with improved quality of life.

Abstract
AIMS OF THE STUDY The lack of suitable donor organs limits the number of solid organ transplants. Patients who underwent cardiopulmonary resuscitation (CPR) after cardiac arrest may represent a sizeable subgroup of deceased organ donors, as they often progress to brain death or have life-sustaining therapy withdrawn. We aimed to quantify deceased organ donation after CPR in Switzerland for the first time by analysing the characteristics of potential and utilised organ donors after CPR. METHODS Data on deceased adult and paediatric patients who were reported to and approved by Swisstransplant for organ donation were analysed, including both donation after brain death (DBD) and donation after controlled cardiocirculatory death (cDCD) from 2016 to 2018. We analysed baseline characteristics of potential donors who underwent CPR in the context of their hospitalisation, as compared with donors without prior CPR. Considering the varying characteristics between these two donor groups, we assessed the effect of CPR on different allocation outcomes (donor and organ utilisation, organ yield per utilised donor) using multivariable regression. Additionally, we present selected CPR circumstances and compared different subgroups of CPR donors according to duration of CPR and duration of no-flow time. RESULTS Of the 461 deceased potential organ donors included in the analysis, 173 (37.5%) underwent CPR. CPR donors were, on average, younger (median age 53 vs 62, p <0.001), had different causes of death (p <0.001), and were more often of the cDCD type (30.1% vs 18.4%, p = 0.004) as compared with non-CPR donors. Of the 173 CPR donors, 152 (87.9%) could be utilised (minimum one organ transplanted), and in the multivariable analysis, utilisation rate was higher in the CPR donor group than in the non-CPR donor group (odds ratio 3.3, 95% confidence interval 1.1–11.5; p = 0.046). Organ specific utilisation of heart, liver, and kidney, and total organ yield per donor, did not differ significantly between CPR and non-CPR donors. CONCLUSION Our study reveals that a substantial proprotion of deceased organ donors in Switzerland underwent CPR in context of their hospitalisation. CPR donors are different from non-CPR donors with respect to age, cause of death and donation type. However, when carefully selected according to their haemodynamic condition, CPR donors are comparable to non-CPR donors in terms of donor and organ utilisation, as well as the average organ yield. Thus, all patients who are resuscitated from cardiac arrest but who subsequently progress to death should be evaluated for organ donation. How CPR donors compare with non-CPR donors regarding transplant outcomes should be studied further.

Abstract
AIMS OF THE STUDY The impact of coronavirus disease 2019 (COVID-19) on patients listed for solid organ transplantation has not been systematically investigated to date. Thus, we assessed occurrence and effects of infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on patients on the Swiss national waiting list for solid organ transplantation. METHODS Patient data were retrospectively extracted from the Swiss Organ Allocation System (SOAS). From 16 March to 31 May 2020, we included all patients listed for solid organ transplantation on the Swiss national waiting list who were tested positive for SARS-CoV-2. Severity of COVID-19 was categorised as follows: stage I, mild symptoms; stage II, moderate to severe symptoms; stage III, critical symptoms; stage IV, death. We compared the incidence rate (laboratory-confirmed cases of SARS-CoV-2), the hospital admission rate (number of admissions of SARS-CoV-2-positive individuals), and the case fatality rate (number of deaths of SARS-CoV-2-positive individuals) in our study population with the general Swiss population during the study period, calculating age-adjusted standardised incidence ratios and standardised mortality ratios, with 95% confidence intervals (CIs). RESULTS A total of 1439 patients were registered on the Swiss national solid organ transplantation waiting list on 31 May 31 2020. Twenty-four (1.7%) waiting list patients were reported to test positive for SARS-CoV-2 in the study period. The median age was 56 years (interquartile range 45.3–65.8), and 14 (58%) were male. Of all patients tested positive for SARS-CoV-2, two patients were asymptomatic, 14 (58%) presented in COVID-19 stage I, 3 (13%) in stage II, and 5 (21%) in stage III. Eight patients (33%) were admitted to hospital, four (17%) required intensive care, and three (13%) mechanical ventilation. Twenty-two patients (92%) of all those infected recovered, but two male patients aged >65 years with multiple comorbidities died in hospital from respiratory failure. Comparing our study population with the general Swiss population, the age-adjusted standardised incidence ratio was 4.1 (95% CI 2.7–6.0). CONCLUSION The overall rate of SARS-CoV-2 infections in candidates awaiting solid organ transplantation was four times higher than in the Swiss general population; however, the frequency of testing likely played a role. Given the small sample size of affected patients, conclusions have to be drawn cautiously and results need verification in larger cohorts.

Abstract
For infants, children, and adolescents with progressive advanced lung disease, lung transplantation represents the ultimate therapy option. Fortunately, outcomes after pediatric lung transplantation have improved in recent years now producing good long-term outcomes, no less than comparable to adult lung transplantation. The field of pediatric lung transplantation has rapidly advanced; thus, this review aims to update on important issues such as transplant referral and assessment, and extra-corporal life support as "bridge to transplantation". In view of the ongoing lack of donor organs limiting the success of pediatric lung transplantation, donor acceptability criteria and surgical options of lung allograft size reduction are discussed. Post-transplant, immunosuppression is vital for prevention of allograft rejection; however, evidence-based data on immunosuppression are scarce. Drug-related side effects are frequent, close therapeutic drug monitoring is highly advised with an individually tailored patient approach. Chronic lung allograft dysfunction (CLAD) remains the Achilles' heel of pediatric lung transplant limiting its long-term success. Unfortunately, therapy options for CLAD are still restricted. The last option for progressive CLAD would be consideration for lung re-transplant; however, numbers of pediatric patients undergoing lung re-transplantation are very small and its success depends highly on the optimal selection of the most suitable candidate.

Abstract
BACKGROUND Severe acute respiratory syndrome - coronavirus-2 (SARS-CoV-2) has caused a pandemic threatening the life of people with chronic respiratory diseases including cystic fibrosis (CF). This study was designed to investigate health-related aspects of individuals with CF, with and without lung transplantation (LTX), their communication with their specialist healthcare providers during the pandemic, potential changes in peoples' individual therapy regimes and daily physical activity levels. METHODS A web-based survey was conducted among Swiss adults with CF with and without LTX, study period from March 16th, 2020 - the day the "extraordinary situation" was officially declared in Switzerland introducing stringent measures protecting the public - until May 16th, 2020. RESULTS 327 individuals (25% LTX recipients) were included, 45 individuals reported coronavirus-2019 disease (COVID-19) like symptoms. Of 28 subjects tested, only three subjects were tested positive, all with mild symptoms, no hospitalization required. Almost half of the survey respondents (45%) reported undertaking less physical activity during the lockdown, while 79% and 91% of participants reported no change in traditional airway clearance and inhalation therapies, respectively. Distress regarding a potential SARS-CoV-2 infection or worsening of lung disease were no major concerns for subjects. CONCLUSIONS Our study reveals that the direct impact of SARS-CoV-2 on clinical outcomes of individuals with CF was mild although people with chronic lung diseases like CF are considered a high-risk population; overall, this is reassuring. However, strict lockdown measures substantially affected peoples' physical activity levels, a vital cornerstone of CF therapy; and this is worrisome.

Abstract
Extra-corporeal photopheresis (ECP) is known as safe ultimate treatment option for chronic lung allograft dysfunction (CLAD). Here, we report the first case of ECP as "second-line" immunomodulatory therapy early post-transplant in an adult patient undergoing lung transplantation for severe chronic thromboembolic pulmonary hypertension, complicated by impaired consciousness due to idiopathic hyperammonemia resulting in recurrent hypercapnic respiratory failure. ECP was initiated twice weekly on post-transplant day 25 and standard triple immunosuppression reduced. Within 2 weeks, the clinical status improved. ECP has been continued every 4 weeks after discharge. At 1 year post-transplant, ECP was stopped as maintenance immunosuppression was reached. We recommend to consider the immunomodulatory effect of ECP as "second line" immunomodulatory therapy in cases where standard immunosuppression causes severe collateral damage. ECP is able to assist prevention of allograft rejection in conjunction with reduced levels of standard immunosuppression, even in the early period following lung transplantation.

Abstract
Bronchoalveolar lavage (BAL) is a key clinical and research tool in lung transplantation (LTx). However, BAL collection and processing are not standardized across LTx centers. This International Society for Heart and Lung Transplantation-supported consensus document on BAL standardization aims to clarify definitions and propose common approaches to improve clinical and research practice standards. The following 9 areas are covered: (1) bronchoscopy procedure and BAL collection, (2) sample handling, (3) sample processing for microbiology, (4) cytology, (5) research, (6) microbiome, (7) sample inventory/tracking, (8) donor bronchoscopy, and (9) pediatric considerations. This consensus document aims to harmonize clinical and research practices for BAL collection and processing in LTx. The overarching goal is to enhance standardization and multicenter collaboration within the international LTx community and enable improvement and development of new BAL-based diagnostics.

Abstract
AIMS OF THE STUDY Lung transplantation is an established therapy in selected patients with advanced cystic fibrosis lung disease. Resumption of employment after lung transplantation is generally supported. In Switzerland, there are no data on long-term employment in people with cystic fibrosis undergoing lung transplantation. METHODS In a single-centre, cross-sectional study at a Swiss university hospital, clinical data from lung transplant recipients with cystic fibrosis, covering the transplantation period from January 1996 to December 2016, were analysed retrospectively. The potential influence of pre-lung transplantation factors (age, sex, lung function, body mass index, six-minute walk test distance, lung transplantation wait list time, paid employment on the wait list, education, relationship status, housing situation) and post-lung transplantation factors (chronic allograft dysfunction [CLAD], dialysis, cancer diagnosis [except skin cancer]) on paid employment and work percentage after lung transplantation were investigated using mixed logistic and linear regression models. Descriptive analyses of paid employment were performed for various periods after lung transplantation (<1, 1–3, 3–5, 5–10, >10 years). Data are reported as odds ratios (ORs) or coefficients (β) with their 95% confidence intervals (CIs). RESULTS Eighty-four subjects (46.4% female) with a mean ± SD age of 29.9 ± 8.4 years were included in the study. Mean wait time for lung transplantation was 42.7 ± 40.2 weeks. The number (percentage) of subjects employed <1 year, 1–3 years, 3–5 years, 5–10 years and >10 years after lung transplantation was n = 23 (28%), n = 51 (65%), n = 44 (75%), n = 30 (68%) and n = 21 (75%), respectively. In mixed logistic regression models, pre-lung transplantation paid employment (OR 24.03, 95% CI 6.08 to 164.39, p <0.0001), academic education (OR 7.81, 95% CI 1.66 to 48.66, p = 0.01) and time post lung transplantation (on log scale, OR 5.81, 95% CI 3.15 to 12.78, p <0.0001) were the main factors influencing post-lung transplantation paid employment status. In mixed linear regression models, pre-lung transplantation paid employment (β = 21.40, 95% CI 10.98 to 31.81, p = 0.00014), academic education (β = 12.54, 95% CI 0.48 to 24.55, p = 0.05) and time post lung transplantation (on log scale, β = 8.96, 95% CI 6.17 to 11.82, p <0.0001) were the main factors influencing work percentage post lung transplantation. No evidence for an influence of clinical factors such as CLAD, cancer or dialysis on post-lung transplantation employment and work percentage was found. CONCLUSION Pre-transplant employment is the dominant factor influencing lung transplantation employment in people with cystic fibrosis. People with cystic fibrosis undergoing lung transplantation should be encouraged to work for as long as their health status permits. Professional reintegration after successful lung transplantation should be supported by a multi-disciplinary lung transplant team.

Abstract
Since the first successful lung transplants in humans were done in the 1980s, lung transplantation has become an established treatment for end-stage pulmonary disease. Because the access to transplantable organs is limited and unpredictable, rules that guide the allocation of lungs for transplants have emerged. Such rules are governed not only by medical and bioethical necessities, but also by local traditions, legislation, and practical circumstances. Therefore, there may be significant differences between the organ allocation practices in various parts of the world. In this brief communication, the European perspective on lung allocation is presented, also adding a very brief description of other parts of the world.

Abstract
Allergy transfer upon solid organ transplantation has been reported in the literature, although only few data are available as to the frequency, significance, and management of these cases. Based on a review of 577 consecutive deceased donors from the Swisstransplant Donor-Registry, 3 cases (0.5%) of fatal anaphylaxis were identified, 2 because of peanut and 1 of wasp allergy. The sera of all 3 donors and their 10 paired recipients, prospectively collected before and after transplantation for the Swiss Transplant Cohort Study, were retrospectively processed using a commercial protein microarray fluorescent test. As early as 5 days posttransplantation, newly acquired peanut-specific IgE were transiently detected from 1 donor to 3 recipients, of whom 1 liver and lung recipients developed grade III anaphylaxis. Yet, to define how allergy testing should be performed in transplant recipients and to better understand the impact of immunosuppressive therapy on IgE sensitization, we prospectively studied 5 atopic living-donor kidney recipients. All pollen-specific IgE and >90% of skin prick tests remained positive 7 days and 3 months after transplantation, indicating that early diagnosis of donor-derived IgE sensitization is possible. Importantly, we propose recommendations with respect to safety for recipients undergoing solid-organ transplantation from donors with a history of fatal anaphylaxis.

Abstract
Background Barriers and motives towards physical activity (PA) in lung transplant (LTx) recipients with cystic fibrosis (CF) are largely unknown. We aimed to explore perceptions towards PA in LTx recipients with CF to better understand individuals’ needs and preferences. Methods Participants completed an online survey at two Swiss LTx and one follow-up shared care centre between June and December 2018. Results One hundred and eleven individuals completed the survey (87.4% response rate). Overall, survey participants perceive PA as important for their daily life and health. Perceived motives of PA were improving muscle strength, endurance and quality of life (QoL), to feel better, fun, to achieve personal goals and having more energy for everyday life. Fatigue was the most common perceived barrier to PA and associated with poorer QoL (r = -0.43, p<0.001) and health status (r = -0.31, p = 0.001). Participants with lung allograft dysfunction (LAD, n = 20) reported lower habitual PA (p = 0.009) and health status (p = 0.011), and rated shortness of breath, bad weather and concerns regarding lung rejection higher than those without LAD (all p<0.05). When we asked how an optimal training programme should look like, the majority would prefer individual, non-supervised (60%), outdoor (77%), endurance training (90%), once or twice a week (47%) for 40–60 minutes (48%). Only a minority of patients (14%) would be willing to use exercise applications for their home-based training. Conclusions LTx recipients with CF value PA as important for their health. People with CF should be encouraged individually by their multidisciplinary transplant team to implement PA in their daily life, potential barriers should be identified and addressed. Overall, knowledge on perceived barriers and motives for PA should be considered in the development of future patient-centred PA programmes.

Abstract
Working After Lung Transplantation Abstract. Whether patients return to work after a successful lung transplant depends on various factors. The best predictive factor for employment after transplantation is the employment status before transplantation. Currently, there is no internationally standardized procedure regarding the questions of when and according to what criteria patients should be reintegrated into the working environment after lung transplantation. The risk of infection at the workplace/during the work activity should definitely be assessed before resuming work: a detailed work history is mandatory, an additional workplace inspection a further option. Advice should be based on the medical literature and general recommendations, and psychosocial factors must also be taken into account. In case of ambiguities, an interdisciplinary discussion is recommended.

Abstract
Objective The aim of this review was to describe how patients experience an exacerbation of cystic fibrosis in terms of symptom management. Methods A systematic literature search was performed in MEDLINE, CINAHL, EMBASE, PSYCINFO and ASSIA. Studies were included that contained any direct quotes or summaries of quotes from patients with cystic fibrosis aged 16 or older and were related to symptom experience and management during an exacerbation. Framework analysis, guided by Symptom Management Theory, was used to present the findings. Results The review included 18 qualitative studies. In addition to physiological symptoms, patients highlighted the significant role of psychological symptoms. Delayed help-seeking was a common first response. Participants choose their self-management strategies taking both physiological and psychological symptoms into account. Maintaining normality was an important short-term outcome for patients, leading to conflict with health professionals. Patients’ symptom management during exacerbation was greatly influenced by the structure of cystic fibrosis care. Discussion Our findings provide an initial understanding of factors influencing patient self-management during an exacerbation. The transferal of these findings into clinical practice will provide a basis for shared goal setting and intervention planning. In addition, our findings have implications for future development of patient-reported outcome measures and intervention research.

Abstract
Bronchiolitis obliterans syndrome is the main limitation for long-term survival after lung transplantation. Some specific B cell populations are associated with long-term graft acceptance. We aimed to monitor the B cell profile during early development of bronchiolitis obliterans syndrome after lung transplantation. The B cell longitudinal profile was analyzed in peripheral blood mononuclear cells from patients with bronchiolitis obliterans syndrome and patients who remained stable over 3 years of follow-up. CD24hi CD38hi transitional B cells were increased in stable patients only, and reached a peak 24 months after transplantation, whereas they remained unchanged in patients who developed a bronchiolitis obliterans syndrome. These CD24hi CD38hi transitional B cells specifically secrete IL-10 and express CD9. Thus, patients with a total CD9+ B cell frequency below 6.6% displayed significantly higher incidence of bronchiolitis obliterans syndrome (AUC = 0.836, PPV = 0.75, NPV = 1). These data are the first to associate IL-10-secreting CD24hi CD38hi transitional B cells expressing CD9 with better allograft outcome in lung transplant recipients. CD9-expressing B cells appear as a contributor to a favorable environment essential for the maintenance of long-term stable graft function and as a new predictive biomarker of bronchiolitis obliterans syndrome-free survival.

Abstract
Early diagnosis and treatment of acute cellular rejection (ACR) may improve long-term outcome for lung transplant recipients (LTRs). Cytokines have become valuable diagnostic tools in many medical fields. The role of bronchoalveolar lavage (BAL) cytokines is of unknown value to diagnose ACR and distinguish rejection from infection. We hypothesized that distinct cytokine patterns obtained by surveillance bronchoscopies during the first year after transplantation are associated with ACR and microbiologic findings. We retrospectively analyzed data from 319 patients undergoing lung transplantation at University Hospital Zurich from 1998 to 2016. We compared levels of IL-6, IL-8, IFN-γ and TNF-α in 747 BAL samples with transbronchial biopsies (TBB) and microbiologic results from surveillance bronchoscopies. We aimed to define reference values that would allow distinction between four specific groups “ACR”, “infection”, “combined ACR and infection” and “no pathologic process”. No definitive pattern was identified. Given the overlap between groups, these four cytokines are not suitable diagnostic markers for ACR or infection after lung transplantation.

Abstract
BACKGROUND Influenza virus infections in lung transplant recipients (LTRs) have an increased risk of unfavourable outcomes. Early initiation of treatment is associated with improved outcomes. In clinical practice, empirical oseltamivir treatment is therefore commonly started prior to diagnostic microbiological confirmation. There is limited data on the patient characteristics, outcomes and safety of this practice. This study investigated outcomes and safety of this pre-emptive treatment strategy using oseltamivir. METHODS Descriptive analysis of LTRs who received oseltamivir for ≥2 days for suspected influenza infection between July 2011 and June 2012. Analyses were based on data from electronic medical records and our standardized LTR database with prospective documentation of clinical information including medication, laboratory and radiological results, outcomes and adverse events. RESULTS We included 133 patients with a total of 261 oseltamivir treatment episodes (87.4% as outpatients). Median duration of oseltamivir treatment was 4 days (range 2 to 67) and 98.5% had concomitant antibiotic pharmacotherapy. Indications for oseltamivir included acute respiratory infection (66.7%), non-distinctive inflammatory reaction (51.3%) and influenza-like illness (2.7%). Influenza virus infection was confirmed by PCR in only 7%. Rhinovirus was the most frequent pathogen detected (14.9%). We discovered a wide range of adverse events but none occurred in >5%, and most were mild and of questionable causal relationship to oseltamivir administration. CONCLUSIONS This non-controlled retrospective analysis suggests that the pre-emptive use of oseltamivir for respiratory tract infections pending microbiological results is safe in LTRs.

Abstract
Although it is well known that a lung transplant enhances the recipient's quality of life, our knowledge of how it is processed mentally is limited. In this study, interviews were conducted with a lung-transplant patient two weeks, three months, and six months after surgery so as to investigate the relevant unconscious processing mechanisms. A dream reported in the first interview was analysed in accordance withapplying the Zurich Dream Process Coding System. A 'transplantation complex' was reconstructed on the basis of various sources of information (the dream and the waking narratives). The principal aspects of the transplantation complex that emerged from both the dream and the waking narratives concerned the oral-sadistic phantasy that the donor had been killed and that his lung, or soul, had been violently incorporated in the patient. The main unconscious themes involved in the processing of the transplant were found to have been already laid down in the dream and to have been presented in it in the form of visual analogues. According to our interpretation of the data analysed, powerful cannibalistic phantasies and death wishes played an important part in the processing of the transplant. These archaic phantasies may have been actualized by the transplant.

Abstract
OBJECTIVES Human leucocyte antigen (HLA) mismatch between donor and recipient has a differential impact on the outcome after transplant (Tx) among transplantable solid organs. Although the lung is considered a highly antigenic organ, the impact of HLA matching between the donor and the recipient has been shown to be heterogeneous on lung Tx outcome. To provide further evidence that HLA matching should be considered in the decision process prior to lung Tx, we evaluated the impact of donor/recipient HLA mismatch on the outcome after lung Tx at our institution. METHODS All patients who underwent lung Tx were analysed in this retrospective single-cohort study between 1994 and 2013 for HLA (-A, -B or -DR) matching between the donor and the recipient and their association with overall survival, the incidence of acute cellular rejection (ACR) and the development of chronic lung allograft dysfunction (CLAD). RESULTS In total, 371 (197 men) patients were included. Of these, 117 patients had no HLA match (0/6), 143 had a 1/6 match, 77 had 2/6 matches, 28 had 3/6 matches and 6 had 4/6 matches. One hundred and twenty-two (33%) patients experienced at least 1 episode of ACR and 172 (46%) patients developed CLAD. Univariate analysis showed a significant correlation between HLA mismatch and the development of CLAD, whereas multivariate analysis revealed that the number of HLA matches (hazard ratio 0.76; P = 0.002), antibodies to cytomegalovirus in either donors or recipients (hazard ratio 1.52; P = 0.036) and donor age (hazard ratio 1.03; P < 0.001) were independent risk factors for the development of CLAD. On the other hand, HLA matches did not correlate with the incidence of ACR and with the overall survival rate. CONCLUSIONS The number of HLA mismatches between donors and recipients after lung Tx did not correlate with ACR or with the overall survival. In contrast, HLA mismatch correlated with the development of CLAD and should therefore be considered a risk factor.

Abstract
Objective: Bone disease is a common comorbidity in patients with cystic fibrosis (CF). We sought to determine risk factors and identify potential biochemical markers for CF-related bone disease (CFBD) in a unique cohort of CF patients with end-stage lung disease undergoing lung transplantation (LTx) evaluation. Methods: All of the CF patients who were evaluated for LTx at our center between November of 1992 and December of 2010 were included in the study. Clinical data and biochemical markers of bone turnover, as well as bone mineral density (BMD) at the lumbar spine and femoral neck, were evaluated. Spearman’s rho and multivariate logistic regression analysis were used. Results: A total of 102 adult CF patients were evaluated. The mean age was 28.1 years (95% CI: 26.7-29.5), and the mean body mass index was 17.5 kg/m2 (95% CI: 17.2-18.2). Mean T-scores were −2.3 and −1.9 at the lumbar spine and femoral neck, respectively, being lower in males than in females (−2.7 vs. −2.0 at the lumbar spine and −2.2 vs. −1.7 at the femoral neck). Overall, 52% had a T-score of < −2.5 at either skeletal site. The homozygous Phe508del genotype was found in 57% of patients without osteoporosis and in 60% of those with low BMD. Mean T-scores were not particularly low in patients with severe CFTR mutations. Although the BMI correlated with T-scores at the femoral neck and lumbar spine, serum 25-hydroxyvitamin D and parathyroid hormone levels did not. Conclusions: CFBD is common in CF patients with end-stage lung disease, particularly in males and patients with a low BMI. It appears that CF mutation status does not correlate with CFBD. In addition, it appears that low BMD does not correlate with other risk factors or biochemical parameters. The prevalence of CFBD appears to have recently decreased, most likely reflecting increased efforts at earlier diagnosis and treatment.

Abstract
BACKGROUND
Lung transplantation (LTx) provides a viable option for the survival of end-stage lung diseases. Besides survival as a clinical outcome measure, health-related quality of life (HRQoL) and psychological distress have become important outcomes in studies investigating the effectiveness of LTx in the short- and long-term.
OBJECTIVE
To assess and compare HRQoL trajectories of patients after LTx prior to and over a follow-up period of three years post-transplant, and to identify differences regarding distress, HRQoL and patient-related outcomes.
METHODS
In this longitudinal study, 27 lung transplant recipients were prospectively examined for psychological distress (Symptom Checklist short version-9; SCL-K-9), health-related quality of life (EuroQOL five dimensions questionnaire; EQ-5D), depression (HADS-Depression scale), and socio-demographic and medical outcomes at two weeks, three months, six months and three years following LTx. Additionally, potential outcome-related predictors for LTx-outcomes at three years post-transplant were assessed. Data were collected in accordance with guidelines set by the STROBE (strengthening the reporting of observational studies in epidemiology) statement.
RESULTS
Lung transplant recipients showed the most pronounced improvements in HRQoL and reduction in psychological distress between two weeks and three months post-transplant, with relative stable HRQoL and distress trajectories thereafter. The most important predictors of poor somatic health trajectories over time were the pre-transplant disease severity score and the pre-transplant HADS-Depression score. In addition, idiopathic pulmonary fibrosis (IPF) and pre-transplant extracorporeal membrane oxygenation (ECMO)-use predicted poorer survival, while cystic fibrosis was associated with better survival three years post-transplant.
COMCLUSION
Lung transplantation yields significant survival and HRQoL benefits, with its peak improvement at three months post-transplant. The majority of patients can preserve these health changes in the long-term. Patients with a worse HRQoL and higher psychological distress at six months post-transplant tended to have a poorer survival post-transplant. Other risk factors for poorer survival included IPF, pre-transplant ECMO-use, pre-transplant symptoms of depression, high pre-transplant disease severity and worse somatic disease severity trajectories. The majority of LTx-recipients were unable to work due to illness-related reasons.

Methods In this longitudinal study, 27 lung transplant recipients were prospectively examined for psychological distress (Symptom Checklist short version-9; SCL-K-9), health-related quality of life (EuroQOL five dimensions questionnaire; EQ-5D), depression (HADS-Depression scale), and socio-demographic and medical outcomes at two weeks, three months, six months and three years following LTx. Additionally, potential outcome-related predictors for LTx-outcomes at three years post-transplant were assessed. Data were collected in accordance with guidelines set by the STROBE (strengthening the reporting of observational studies in epidemiology) statement. Results Lung transplant recipients showed the most pronounced improvements in HRQoL and reduction in psychological distress between two weeks and three months post-transplant, with relative stable HRQoL and distress trajectories thereafter. The most important predictors of poor somatic health trajectories over time were the pre-transplant disease severity score and the pre-transplant HADS-Depression score. In addition, idiopathic pulmonary fibrosis (IPF) and pre-transplant extracorporeal membrane oxygenation (ECMO)-use predicted poorer survival, while cystic fibrosis was associated with better survival three years post-transplant. Conclusion Lung transplantation yields significant survival and HRQoL benefits, with its peak improvement at three months post-transplant. The majority of patients can preserve these health changes in the long-term. Patients with a worse HRQoL and higher psychological distress at six months post-transplant tended to have a poorer survival post-transplant. Other risk factors for poorer survival included IPF, pre-transplant ECMO-use, pre-transplant symptoms of depression, high pre-transplant disease severity and worse somatic disease severity trajectories. The majority of LTx-recipients were unable to work due to illness-related reasons.

Abstract
BACKGROUND The presence of pan-resistant organisms in patients with cystic fibrosis (CF) potentially impacts mortality after lung transplant (LT). In this study we aimed to study LT mortality in CF patients with and without pan-resistant infection. METHODS The International Society for Heart and Lung Transplantation (ISHLT) Thoracic Transplant Registry was used to identify adults with CF, first-time, bilateral LT from 1991 to 2015. Extracted data included demographics, clinical characteristics, post-transplant outcomes, and mortality (infection-related, overall). Multivariate binary logistic regression models were created with 90-day and 1-year mortality as primary outcomes. RESULTS Among 3,256 LT recipients with CF, 697 were labeled as having pan-resistant infection, the others were included as controls (n = 2,649). Pre-transplant, those labeled as pan-resistant were more likely to require ventilator support, have an infection requiring intravenous antibiotics, and have had ≥2 pneumonia episodes within 1 year. Ninety-day and 1-year mortality was similar between groups, but infection-related mortality at 90days (3.3% vs 1.88%, p = 0.01) and 1 year (6.6% vs 4.6%, p < 0.001) was higher in those labeled as pan-resistant. In multivariate analysis, presence of organisms labeled as pan-resistant was not associated with 90-day (odds ratio [OR] 1.5, 95% confidence interval [CI] 0.93 to 2.42, p = 0.09) or 1-year mortality (OR 1.32, 95% CI 0.95 to 1.83, p = 0.097). CONCLUSIONS CF patients with pre-transplant infection from organisms labeled as pan-resistant had similar 90-day and 1-year mortality as those without. Despite increased infection-related mortality in these patients, it was not predictive of mortality in multivariate analysis. The higher occurrence of post-transplant infections in these patients warrants diligent follow-up. A multicenter cohort study will be required to validate the findings of our study.

Abstract
Zusammenfassung
Hintergrund Der Einsatz von Antibiotika gehört zum medizinischen Alltag. Ein dabei häufig eingesetzter Wirkstoff ist die Gruppe der Chinolone. Physiotherapeutisch relevant sind deren muskuloskeletale Nebenwirkungen, insbesondere auf das Sehnengewebe. Meist sind die Achillessehnen durch Tendinopathien oder Rupturen betroffen. Es besteht ein Mangel an Literatur bezüglich der Pathophysiologie als auch der Rehabilitation dieser klinischen Muster.
Ziel Diese Fallstudie evaluierte die Anwendung eines exzentrischen Trainingsprotokolls bei chinoloninduzierter Tendinopathie der Achillessehne.
Methode Die physiotherapeutische Rehabilitation einer 48-jährigen Frau mit unilateraler Tendinopathie der Achillessehne unter Einnahme des Antibiotikums Ciprofloxacin nach Lungentransplantation wird beschrieben. Dabei wurde ein kriterienbasierter Ansatz mit ausschließlich Hands-off-Therapie unter Einsatz eines exzentrischen Belastbarkeitsaufbaus der Achillessehne angewendet.
Ergebnisse Nach 9 Einzeltherapien fanden sich Verbesserungen beim 1-Minute-Sitz-Stand-Test, der Range of Motion bei Dorsalextension des oberen Sprunggelenks rechts, beidseitige Kraft von Knieextensoren und -flexoren, Dorsalextensoren und Plantarflexoren des oberen Sprunggelenks, beim VISA-A-Fragebogen sowie bei Schmerz und Partizipation.
Schlussfolgerungen Bei chinoloninduzierter Tendinopathie der Achillessehne ist ein exzentrisch betontes Trainingsprotokoll durchführbar und wirksam, wobei die zahlreichen Komorbiditäten der primär betroffenen Population zu beachten sind. Da Physiotherapeuten aufgrund der demografischen Entwicklung zunehmend mit hochkomplexen Fällen konfrontiert werden, ist es für sie wichtig, die unerwünschten Wirkungen von Medikamenten zu kennen.
