Cystic fibrosis is an autosomal progressive disease affecting the lung, pancreas, and liver. Some patients develop end-stage respiratory and liver failure. For such patients, combined lung-liver transplantation remains the only therapeutic option. In this article we present the first simultaneous lung-liver transplantation in Poland, as well as in Central and Eastern Europe, with detailed clinical history, surgical aspects, and postoperative course., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022.

BACKGROUND Lung transplant recipients may suffer from airway stenosis (AS). The aim of this study was to assess whether pulmonary function (as measured by spirometry and a 6-minute walk test [6MWT]) in patients with AS treated consistently with bronchoscopic interventions (BIs) was comparable to that in their AS-free counterparts at the 1-year follow-up visit. MATERIAL AND METHODS Fifty patients who underwent primary double-lung transplantation between January 2015 and March 2019 at a single center (23 who received BIs and 27 who did not) were enrolled in this retrospective study. Graft function was assessed with spirometry, based on forced expiratory volume (FEV₁) and forced vital capacity (FVC), both measured in liters (L) and percentages (%), and the Tiffeneau-Pinelli index (FEV₁/FVC), and a 6MWT and parameters such as oxygen saturation measured before and after the test. RESULTS Patients in need of BIs had significantly lower FEV₁% compared with individuals who did not receive BIs during their first post-transplant year. Airway obstruction was present in 22% of patients who did not receive BIs and 65.23% of those who did receive the interventions. There were statistically significant, strong, negative correlations pertaining to the number of balloon BIs and 1-year FEV₁% (rs=0.67) as well as the number of balloon BIs and 1-year FEV₁/FVC (rs=0.72). A statistically significant, strong, negative correlation (rs=0.75) was found between the number of balloon bronchoplasty treatments and oxygen saturation after the 6WMT. CONCLUSIONS Despite receiving BIs, patients who experience bronchial stenosis may not obtain the expected ventilatory improvement at their 1-year follow-up visit. Their AS may recur or persist despite use of various procedures. Further study in that regard is required.

Infant respiratory distress syndrome (IRDS) develops among premature infants due to structural immaturity of the lungs and insufficient production of pulmonary surfactant. Nowadays, treatment takes place under conditions of intensive care and includes oxygen therapy, mechanical ventilation, exogenous supplementation of pulmonary surfactant and antenatal corticosteroid therapy. The treatment of IRDS, especially mechanical ventilation, may lead to complications which can contribute to developing a severe dysfunction of the respiratory system. Unavailability of pharmacological treatment of IRDS and development of pulmonary barotrauma due to mechanical ventilation in our patient led to the forming of severe pulmonary interstitial emphysema. In this case report, lung transplantation was performed as an only successful therapeutic option.

A 44-year-old male with no history of underlying diseases was referred to academic hospital due to ARDS with confirmed SARSCoV-2 infection after 7 days of mechanical ventilation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated as no improvement was noted in prone position. Mechanical ventilation was continued with TV of 3-4 mL/kg. A gradual decline of static lung compliance was observed from baseline 35 mL/cm H20 to 8 mL/cm H2O. The chest CT scan revealed extensive ground-glass areas with a significant amount of traction bronchiectasis after 3 weeks since admission. When the patient was negative for SARS-CoV-2 during the 4th week of ECMO, the decision to perform an emergency lung transplantation (LTx) was made based on the ongoing degradation of lung function and irreversible damage to lung structure. The patient was transferred to the transplant center where he was extubated, awaiting the transplant on passive oxygen therapy and ECMO. Double lung transplantation was performed on the day 30th of ECMO. Currently, the patient is self-reliant. He does not need oxygen therapy and continues physiotherapy. ECMO may be life-saving in severe cases of COVID-19 ARDS but some of these patients may require LTx, especially when weaning proves impossible. VV ECMO as a bridging method is more difficult but ultimately more beneficial due to insufficient number of donors, and consequently long waiting time in Poland.

Background: Cystic fibrosis is a congenital, progressive disease affecting many organs. It frequently leads to severe respiratory failure, which can be treated by means of a double lung transplantation. Single lung transplantation is justified only in certain cases., Case Report: This is a case report describing a 20-year-old female patient who became the recipient of a single lung transplant as a result of cystic fibrosis. The transplant was performed during cardiothoracic surgery, which included an intervention in the right atrium. At the age of 14, the patient underwent left pneumonectomy. In addition, the patient had a percutaneous endoscopic gastrostomy placed and a vascular port implanted. During preoperative evaluation, she presented with clinical symptoms of chronic respiratory failure. The patient was approved for lung transplantation at the age of 16. After 2 years on the national lung transplant waiting list, in 2018, the patient underwent right lung transplantation and removal of numerous thrombi in the right atrium during 1 procedure. This surgery was accomplished with the use of extracorporeal circulation, which is an extracorporeal membrane oxygenator combined with cardiopulmonary bypass. The patient was discharged 3 weeks after the procedure in good general condition. Presently, her pulmonary function is excellent and she presents with normal respiratory capacity., Conclusions: Patients with cystic fibrosis often require double lung transplantation. Under normal circumstances, performing only a single lung transplantation would be considered medical malpractice. However, in certain cases, a single lung transplant is a life-saving procedure., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

Introduction: Lung transplantation (LTx) is the only effective method of treatment to improve the health and quality of life (QoL) of patients with end-stage lung diseases. After LTx, medical examination accompanied by quality of life assessment should be performed on routine follow-up visits. The aim of the study was to assess the QoL of patients after LTx., Material and Methods: The study group consisted of 60 patients (29 women and 31 men); 20 patients received single lung transplantation (SLT), and 40 received double lung transplantation (DLT). To determine the patient's QoL, the General Health Questionnaire (GHQ), the World Health Organization Quality of Life Test-BREF (WHOQOL-BREF), and the Saint George Respiratory Questionnaire (SGRQ) were used. Spirometry and the 6-minute walk test were analyzed to examine efficiency of transplanted organs., Results: In SGRQ there are differences between patients with cystic fibrosis and interstitial lung disease in symptom domain (20.28% vs 39.26%, P = .025) and total score (19.38% vs 32.47%, P = .028). As reported in the GHQ, men had worse overall results than women in sten scale (5.22 points vs 4.69 points). Patients after SLT achieved similar scores in every questionnaire., Conclusion: Studies assessing QoL should be an important addition to lung function tests and an integral part of control during postoperative follow-up visits. This study is one of the important contributions to understanding of how essential QoL is after LTx. The authors of this study realize that their work does not cover the whole issue, and further studies in this area are warranted., (Copyright © 2020 The Authors. Published by Elsevier Inc.

Introduction: Secondary pulmonary hypertension (PH) is a serious complication of end-stage lung disease and is associated with unfavorable prognosis. The aim of the study was to evaluate the incidence and severity of secondary PH among patients qualified for lung transplantation (LTx)., Material and Methods: The study population consisted of 143 patients qualified for LTx between 2004 and 2019. Analyzed medical records included results collected during the qualification process (eg, echocardiography parameters, right heart catherization [RHC]). There were 37.8% (n = 54) of patients with chronic obstructive pulmonary disease (COPD), 58.7% (n = 84) of patients with interstitial lung diseases (ILDs), and 3.5% (n = 5) of patients with combined pulmonary fibrosis and emphysema (CPFE). The inclusion criteria were ILDs, COPD or CPFE diagnosis, and the presence of RHC data preformed during qualification for LTx. The exclusion criteria were lack of RHC results and diagnosis of idiopathic pulmonary artery hypertension, pulmonary artery hypertension associated with connective tissue disease, cystic fibrosis, or bronchiectasis., Results: PH was detected among 60.1% (n = 86) of patients qualified for LTx. The prevalence of PH was 39% (n = 18) vs 76.19% (n = 64) in the COPD vs ILDs groups, respectively. Both ILDs and COPD patients presented with similar mean artery pulmonary pressure (36.3 ± 9.61 vs 34.78 ± 11.47 mm Hg; not statistically significant). Severe PH was more frequent in the ILDs group than in the COPD group (60.94% vs 38.89%)., Conclusions: PH is commonly diagnosed in patients with chronic lung diseases qualified for LTx and more often observed among patients qualified because of ILDs. It is important to assess the pulmonary pressure because of frequent occurrence of PH among patients referred for LTx., (Copyright © 2020 The Authors. Published by Elsevier Inc.

Background: The cold ischemia time (CIT) is a period of time between harvesting an organ for transplant and its reperfusion just after implantation. CIT may have an impact on frequency of complications after lung transplant that can be treated by means of bronchoscopic intervention. The aim of the study was to investigate the correlation between CIT and frequency of bronchoscopic intervention., Methods: The retrospective study consists of 91 patients: 22 single lung recipients (24%) and 69 double lung recipients (76%) who underwent lung transplant from March 2012 to June 2019. All statistical analyses were performed in SPSS 25.0 and R 3.5.3. The P levels less than .05 were deemed statistically significant., Results: The average CIT in single lung transplant was 5.91 hours, and in double lung transplant it was 8.61 hours. For the 4- to 8-hour CIT the percentages were 80.95% for single lung recipients and 46.38% for double lung recipients. For CIT longer than 8 hours, the following percentages were observed: 9.53% in single lung transplant and 53.62% in double lung transplant. Each subsequent hour of CIT exponentially increases the risk of intervention 1505 times (50.05%)., Conclusions: Prolonged CIT seems to be a risk factor for airway complication, especially in the double lung recipient group., (Copyright © 2020 The Authors.

Background: Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death worldwide. Lung transplantation (LTx) is often the only therapeutic option for patients with end-stage COPD. The aim of the study was to establish whether patients with end-stage COPD benefited from lung transplantation and assess the pulmonary function by the 6-Minute Walk Test (6MWT) and forced expiratory volume in 1 second (FEV1)., Methods: A retrospective study was carried out in the group of 69 patients (40 recipients, 18 patients currently waiting, and 11 patients who died while waiting for a lung graft) diagnosed with end-stage COPD, referred to the Silesian Center for Heart Diseases' Lung Transplant Ward, and qualified to be treated by means of lung transplantation between 2006 and 2018. The beginning of the observation for all 69 patients was a qualification date., Results: Kaplan-Meier estimation determined that graft recipients noted 50% probability of survival at approximately 5.5 years, whereas patients from the other group had such parameters at about 1.4 years. The average results FEV1 obtained at qualification were 23.69% for single lung transplantation (SLT); and 22.06% for double lung transplantation (DLT). Average patient acquired 158.07m in the 6MWT. One year after procedure the average values of FEV1 were SLT, 55.83%; DLT, 79.54%; and 430.7 m in the 6MWT overall., Conclusions: Qualified patients who underwent lung transplantation lived longer than those who did not undergo such a procedure. We observed a difference in SLT and DLT recipients., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: Primary pulmonary hypertension can lead to hypertrophy of the right ventricle and ultimately to its insufficiency. Lung transplantation remains the only viable treatment for patients with certain forms of this disease. Usage of extracorporeal membrane oxygenation in veno-arterial form (VA-ECMO) after transplantation is both protective for left ventricle (enables adaptation to increased blood flow) and right ventricle (provides time to return to appropriate dimensions and in some cases to correct tricuspid regurgitaion)., Case Presentation: The case study describes 4 patients who were treated with VA-ECMO as a perioperative support. Three patients were diagnosed with idiopathic form of precapillary primary pulmonary hypertension. A fourth patient was a 49-year old woman diagnosed with hypoplastic pulmonary veins representing the postcapillary form of pulmonary hypertension. In all of the cases, VA-ECMO was introduced during the surgery (femoral vein/internal jugular vein and femoral artery) and maintained for several days after the transplantation. Regular echocardiographic and biochemical assessment in postoperative course revealed that cardiac function improved during and after such treatment among all patients. They were successfully weaned off ECMO and finally surgically explanted without any local complications. One patient was treated with awake ECMO protocol., Conclusions: VA-ECMO was proved to be a useful tool during the transplantation and postoperative period. It helps to restore proper cardiac function, as well as prevent adverse effects of aforementioned pathologic changes of a heart., (Copyright © 2020 The Authors. Published by Elsevier Inc.

Background: Interstitial lung diseases (ILDs) are a heterogeneous group of more than 200 diseases manifested by progressive exercise dyspnea, radiological lung changes, and ventilation restrictive disorders. ILDs are the second most common indication for lung transplantation (LTx). Our study group consisted of 139 patients who qualified for LTx at the Silesian Center for Heart Diseases between 2004 and 2018. Of the 139, 92 patients died while on the waiting list, and 47 patients underwent LTx. Medical records including laboratory test results, spirometry, and the 6-minute walk test (6MWT) were analyzed to determine eligibility for LTx. We also assessed quality of life post-LTx., Results: Patients who qualified for LTx showed decreased values of parameters measured by spirometry (43.69 ± 19.05% of forced expiratory volume in the first second [FEV1] and 43.07 ± 20.55% of forced vital capacity [FVC] and severe desaturation during the 6MWT (SpO 2  = 88.78% before 6-minute walk test and 73.23% after the test). After LTx, longer distances were achieved in the 6MWT (235.47 ± 159.57 m during qualification vs 533.2 ± 34.15 m 12 months after LTx) and increased values of spirometry. On average, patients had stopped working 6 years prior to LTx., Conclusion: There is no effective medical treatment for patients with end-stage ILDs. Therefore, lung transplantation is a lifesaving procedure for patients that also extends patients' lives and improves their quality of life., (Copyright © 2020 The Authors. Published by Elsevier Inc.

Background: Lung transplantation remains the only viable option for patients with end-stage lung diseases. However, due to an insufficient number of lung donors, many potential candidates die without undergoing the procedure. In the cases of some patients, bridges to transplantation can be implemented. One such method is extracorporeal membrane oxygenation (ECMO), which, depending on the type, has the ability to replace patients' circulatory and respiratory function., Case Presentation: This case study describes 4 cases of patients, who were successfully bridged to lung transplantation. The first patient developed respiratory failure as a result of acute pulmonary embolisms. His respiratory function was insufficient and he had ECMO implanted for 84 days until he was transplanted. Another patient presented respiratory failure due to massive bleeding, which occurred during transbronchial lung biopsy. Such event led to extensive exacerbation, which resulted in using ECMO as a bridge to recovery at first, but later a bridge to lung transplantation. The patient became a lung graft recipient after 14 days on ECMO. The third patient was a woman who developed severe respiratory failure during the course of the progression of her underlying disease. She was treated with ECMO for 14 days as well, and she also underwent lung transplantation. The fourth patient was qualified for retransplantation. She was bridged to retransplantation via veno-venous ECMO., Conclusion: ECMO can be used a bridge to lung transplantation for suitable patients even for a long period of time, given that it is maintained in accordance with the guidelines., (Copyright © 2020 The Authors.

Background: Lung transplant remains the only viable treatment for most of the end-stage lung diseases. It is believed that extending criteria for donor lungs would increase the number of lung transplants. The aim of the study was to compare the graft function by means of oxygenation index among recipients who received the lungs from donors of extended criteria with those whose received lungs from donors who met the standard criteria., Methods: This retrospective study analyzed 71 donors whose lungs where transplanted into 71 first-time double lung recipients of 2 groups: patients who received transplants before and after 2018. The objective was to assess whether there is a significant difference in quality of the donor pool after applying extended criteria. The second objective was to compare results of recipients with lungs from donors of oxygenation index > 400 mm Hg with those obtained among recipients with this parameter < 400 mm Hg., Results: In the case of transplants performed in 2018 to 2019, oxygenation indices were significantly lower in donors but significantly higher in recipients on the first day than those observed in 2015 to 2017. The number of transplants increased from 9 per year to 22 per year. Irrespective of whether the donor had PaO 2 /fraction of inspired oxygen above or below 400 mm Hg, recipients showed similar oxygenation index values after transplant (mean oxygenation index, 462 vs 412 mm Hg, respectively). Short-term mortality did not differ either., Conclusions: Extended criteria of lungs suitability as a potential grafts not only increases the donor pool but also proves that suboptimal donors are not associated with producing inferior results of the recipients., (Copyright © 2020 The Authors.

Background: Lung transplant is a surgical procedure for end-stage lung disease. Many factors related to lung donors influence the outcome of transplant. The main aim of this single-center study was to assess which donor-related and procedure-related factors would influence the 30-day or hospital mortality of the recipients., Methods: This retrospective study group consisted of 110 donor-recipient pairs undergoing lung transplant between 2012 and 2017 (group 1) and 2018 and 2019 (group 2) in Silesian Center for Heart Diseases. Both groups of donor- and procedure-related factors were included in the analysis: oxygenation index at reporting of the donor, time donor spent in the intensive care unit (ICU), presence of cardiac arrest while being in the ICU, donor age, type of transplant, cumulative ischemia time, duration of the operation, and time of mechanical ventilation., Results: The type of surgery was significantly associated with an increase in the chance of death within 30 days. Patients who underwent single lung transplant had a 20.217 times greater chance of dying within 30 days than patients after double lung transplant (interquartile range, 2.116-193.125)., Conclusions: Single lung transplant increases the risk of death during the first 30 days after lung transplant, and using lungs from older donors may increase the rate of hospital mortality. Oxygenation index, sudden cardiac arrest of the donors, and donor time spent in the ICU do not impact the short-term mortality of lung graft recipients., (Copyright © 2020 The Authors.

Background: Lung transplant remains the only viable treatment for certain patients with end-stage lung diseases. Such patients can become either single or double lung recipients. The 2 procedures are associated with specific risks and benefits. The aim of the study was to assess the survival of patients after lung transplant in a single center., Methods: The retrospective study consists of 128 lung transplant recipients. Patients underwent transplant between 2004 and 2017 because of following diseases: chronic obstructive pulmonary disease (28.2%), cystic fibrosis (26.5%), and primary pulmonary hypertension (12.3%), including idiopathic pulmonary arterial hypertension and interstitial lung diseases (33%). Patients with idiopathic pulmonary arterial hypertension were not treated with postoperative extracorporeal membrane oxygenation as left heart conditioning., Results: Regardless of underlying disease, 75% of DLT recipients and 51% of SLT recipients reached 5-year survival (P = .0066). A total of 87% of lung transplant recipients with cystic fibrosis reached 1-year survival. Among lung recipients with primary pulmonary hypertension who underwent DLT and SLT, 5-year survival was reached by 84% and 51%, respectively (P = .025). Among patients with chronic obstructive pulmonary disease, 82% of DLT recipients and 62% of SLT recipients reached 1-year survival (P = .22). Patients who received transplants because of primary pulmonary hypertension presented the worst short-term survival among all SLT recipients., Conclusions: Patients with CF have the best overall survival among all lung transplant recipients. Double lung transplant provides statistically significantly better outcomes than single lung transplant. This observation is also present among recipients who underwent transplant because of primary pulmonary hypertension, as single lung transplant is not recommended among such patients in particular., (Copyright © 2020 The Authors.

Background: Lung transplant (LTx) is a procedure associated with risk of complications related to airway stenosis that can be treated with bronchoscopic interventions (BIs). The aim of the study was to assess the frequency and risk factors associated with increased need of bronchial interventions in the post-transplant period., Methods: The retrospective study reviewed cases of 165 patients (63 women) who underwent LTx from April 2013 to June 2019. For dichotomous discrete variables (occurrence or lack of intervention) multivariate logistic regression analysis was performed to assess the aforementioned risk factors., Results: BIs were required among 38.55% of lung recipients (n = 65). The number of interventions/patient/y decreases between years 1 and 2 (P < .001), 2 and 3 (P = .013), and 3 and 4 (P < .001); after the fourth year post LTx the differences are not statistically significant. Each 1 mm Hg above 25 mm Hg of mean pulmonary arterial pressure causes statistically significant elevation in the number of interventions by 0.7% in the first year after the procedure. The number of BIs per patient among lung recipients who received a transplant because of idiopathic pulmonary arterial hypertension was statistically significantly higher compared with patients with another underlying lung disease., Conclusions: Airway complications developed in the post-transplant period caused a significant number of patients to be in need of BI, especially balloon bronchoplasty. The highest number of interventions occurred within the first year after LTx, and BI decreases over time. Mean pulmonary arterial pressure measured during qualification may have the ability to predict whether the patient would require BI after LTx., (Copyright © 2020 The Authors.

Introduction: Long-term outcomes of airway complications (AC) after lung transplantation are unknown. The incidence of AC varies from 1.6% to 32% with the related mortality rate of 2% to 4%. The management of most AC is based on endobronchial methods, including balloon bronchoplasty, endobronchial stent placement, and ablative techniques. The aim of the study was to assess the connection between airway complications treated by bronchial intervention (BI) and the survival of lung transplant recipients., Materials and Methods: The single-center retrospective study reviewed the cases of 165 patients (63 women [38.18%], 103 men [61, 82%]; median age at referral for lung transplantations (LTx), 41 years [range, 15-68 years]). The cohort was stratified into 2 groups comprising those whose procedures were complicated by ACs and those without. The primary outcome measured was mortality, with survival endpoints calculated at 6 months., Results: The comparison of the survival of recipients regarding underlying disease (cystic fibrosis [CF], chronic obstructive pulmonary disease [COPD], idiopathic pulmonary artery hypertension [IPAH], and others) with the use of the Kaplan-Meier estimator indicated that the only statistically significant (P = .0194) differences between patients who underwent BI and patients without BI performed were observed in CF patients (Fig 1). In any other diagnosis, the results were not statistically significant (P > .05)., Conclusions: Bronchoscopic intervention because of airway complications after lung transplantation are often-used procedures, but they have no impact on the survival of patients with cystic fibrosis., (Copyright © 2020 The Authors.

Background: Model for End-Stage Liver Disease (MELD) score is used to assess the severity of chronic liver disease. It is implemented in transplantology in the process of qualification for urgent liver transplant. The aim of our study was to assess the liver function of patients qualified for lung transplant using MELD score, taking under consideration mean pulmonary artery pressure as an important risk factor of death., Methods: The study group consisted of 123 patients qualified for lung transplant in Silesian Center for Heart Diseases between 2004 and 2017. Data relevant for MELD score calculations and medial pulmonary artery pressure were acquired from medical records., Results: The average MELD score among patients qualified for lung transplant was 8.24 points, and mean pulmonary pressure (mPAP) was 35.02 mm Hg. Patients with idiopathic pulmonary artery hypertension acquired the highest MELD and highest mPAP results (13.1 points and 57.7 mm Hg, respectively). Patients with idiopathic pulmonary fibrosis presented higher mean MELD-Na score among those with pulmonary arterial hypertension than those without pulmonary arterial hypertension (36.59 mm Hg; 7.74 points vs 18 mm Hg; 6.5 points). There is strong positive correlation between MELD-Na and mPAP among patients who underwent lung transplant because of idiopathic pulmonary fibrosis., Conclusions: This is the first study in the worldwide literature assessing MELD-Na as a predictor of survival among patients qualified for lung transplant and those who already are recipients. Further studies regarding this issue are required as authors will explore this issue in the future., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

The aim of the study was to investigate the serum concentration of cytokines (interleukin 6 [IL-6] and IL-10) in patients before and after lung transplantation (LTx). The studied groups consisted of 14 patients (9 men and 5 women aged 47.7 ± 11.4; body mass index [BMI] 21.9 ± 2.3) followed for up to 6 months after LTx and 29 patients (15 men and 14 women, age 49.2 ± 9.4; BMI 23.1 ± 3.7) who were considered for LTx. The study population consisted of patients with idiopathic lung disease (ILD; 8 vs 17) and patients with chronic obstructive pulmonary disease (COPD; 6 vs 12). Cytokine serum levels were assessed using commercially available enzyme-linked immunosorbent assay kits. Significantly lower levels of IL-10 were observed in the group of patients considered for LTx compared to those in recipients (1.8 ± 0.99 vs 5.1 ± 1.44; P = .000726). Significantly lower levels of IL-10 were observed in the group of patients with ILD considered for LTx compared to recipients (1.8 ± 0.95 vs 3.4 ± 1.16; P = .005984). There were no differences in levels of IL-10 in the group of patients with COPD. There were no differences in levels of IL-6 when the studied groups were compared. The present results introduce the cytokines IL-6 and IL-10 in patients before and after LTx. The procedure of LTx influenced increasing of plasma concentration of IL-10. Immunosuppressive drugs may affect IL-10 serum levels. Further studies are needed to evaluate whether analyzed cytokines could be used as biomarkers of clinical status in patients before and after LTx., (Copyright © 2020 Elsevier Inc.

Background: Lung transplantation (LTx) is the only treatment for patients with end-stage lung disease. This procedure is associated with a risk of complications related to airway stenosis, which can be treated by means of bronchoscopic interventions (BI). Microbiological colonization may have an impact on airway complications. The aim of the study was to investigate the effect of presence of microbiological pathogens in graft among lung recipients and frequency of BI, considered as the indicator of severe complications., Materials and Methods: The study design was single-center retrospective cohort research; cases of 116 patients with complete microbiological data who underwent LTx from April 2013 to June 2019 were reviewed (70.3% of transplanted patients). All statistical analyses were performed with SPSS version 25.0 and R 3.5.3. For analyses involving the number of bronchoscopy interventions, univariate and multivariate Poisson regression were used. Interaction effect of variables in multivariate Poisson regression was assessed with partial response plot., Results: The mean number of pathogens colonizing each patient was approximately 4.66 (range, 0 to 19) with Candida albicans (n = 42, 36.2%), Aspergillus spp. (n = 33, 28.4%), Pseudomonas aeruginosa (n = 32, 27.59%), and methicillin-sensitive Staphylococcus aureus (MSSA) (n = 29, 25%) being the most prominent. Microbiological agents causing the greatest increase in the risk of intervention are as follows: Proteus mirabilis by 3.84 times, Aspergillus spp. by 3.53 times, and Stenotrophomonas maltophilia by 3.09 times. Burkholderia multivorans, Enterococcus spp., and Klebsiella spp. do not have a statistically significant impact on the number of BI., Conclusions: Some pathogens increase the frequency of complications, which are associated with deterioration of the general condition. Therefore, patients should be monitored for the presence of pathogens in the airways., (Copyright © 2020 The Authors. Published by Elsevier Inc. All rights reserved.)

Background: The aim of the study was to investigate the serum concentration of cytokines and biochemical markers of malnutrition in correlation with frailty syndrome in patients qualified for lung transplantation (LTx)., Methods: The study population comprised 31 potential lung recipients, including 18 patients with idiopathic lung disease, 12 patients with chronic obstructive pulmonary disease, and 1 patient with bronchiectasis who qualified for a LTx. Cytokine serum levels were assessed using commercially available enzyme-linked immunosorbent assay kits and the Luminex 200 platform (ProcartaPlex Hu Cytokine/Chemokine Panel 1A 34plex, Invitrogen, Carlsbad, Calif., United States). The patients were also asked to complete a questionnaire, the Clinical Frailty Scale., Results: All patients were found to have higher cytokine concentrations (IL6, IL 2,IL18, IL23, IL 12p70, IL 10, IL 7). No statistically significant differences in the analyzed cytokines were noted when the men's results were compared to those of the women. There were no significant differences between patients who scored 6 vs 7 points on the Canadian Study of Health and Aging Function Scale. In comparing chronic obstructive pulmonary disease to idiopathic lung disease patients, no significant differences were observed in the analyzed cytokine values. Significant correlations were observed between the analyzed cytokines and age of the patients, C-reactive protein, triglycerides, transferrin, total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol., Conclusions: Our findings indicate that cytokines may not have a statistically significant effect on the parameters of the frailty syndrome. The results require further investigations on larger study groups. The findings suggest that the analyzed cytokines may play a proinflammatory role in the end stages of lung diseases, but further studies are needed to evaluate whether these cytokines could be used as biomarkers in this group of patients., (Copyright © 2019 Elsevier Inc.

Objectives: Lung transplantation not only saves a patient's life but also creates the opportunity for becoming more self-reliant and getting back to work. The aim of this single center study was to assess the prospects of employment, as well as its influence on the quality of life and physical activity, of the lung transplant recipients of the Silesian Center for Heart Diseases in Zabrze, Poland., Material and Methods: A retrospective study covered 67 lung transplant recipients of the Silesian Center of Heart Diseases. Only patients with ≥ 6-month follow-up were included. All of the patients gave their written consent to be included in the study before filling out the questionnaire containing questions about employment, income, education and how work affected their quality of life before and after lung transplantation. A physical capability assessment was performed by climbing flights of stairs and by means of a 6-min walk test, and spirometry parameters were also measured., Results: Twenty of the patients included in the study (31.7%) were employed after lung transplantation, 63.2% of whom worked full-time. Profession was changed by 2 patients (14.3%). The patients diagnosed with cystic fibrosis were found to have the highest chance of finding employment after lung transplantation. The statistical analysis revealed that the employed patients were able to cover longer distances during the 6-min walk test (556 m, on average) than the unemployed ones (494 m, on average)., Conclusions: One in 3 patients finds employment after lung transplantation. Work improves the quality of life of the majority of lung transplant recipients. The patients who are employed are also in a better physical condition, and they are more self-reliant in comparison to those who remain unemployed. Lung transplant recipients with cystic fibrosis are most likely to find employment, and so are patients with higher education.

BACKGROUND Cystic fibrosis (CF) is congenital multisystem disorder, that leads to gradual deterioration of pulmonary function. Advancements in therapy of CF-related lung disease have delayed its progression. However, lung transplantation remains the only therapeutic option for majority of such patients. Aim of the study was to assess qualification process and outcome of lung transplantation as a treatment of CF patients qualified in a single center between 2011 and 2018. MATERIAL AND METHODS This retrospective study assessed 41 patients who were qualified to be treated by means of lung transplantation due to CF in Lung Transplant Program of Silesian Center for Heart Diseases between 2011 and 2018. Analysis of patients during qualification process and after lung transplantation was performed. Lung recipients were observed during 1-year follow-up by means of pulmonary function tests. RESULTS 1-year survival was noted among 80% of the patients; 3-year survival and 5-year survival were noted among 70% of the recipients. Mean forced expiratory volume in 1 second (FEV1) increased after lung transplantation: 21.19% at qualification; and 76.67% at 12 months after lung transplantation. Mean forced vital capacity (FVC) results also improved: 34.18% at qualification and 78.34% at 12 months after lung transplantation. The 6-minute walk test (6MWT) before and after treatment noted an increase of 175.55 m. CONCLUSIONS Lung transplantation improves respiratory capacity of CF patients and prolongs their life.

Introduction: Idiopathic pulmonary fibrosis (IPF) and chronic obstructive pulmonary disease (COPD) show poor prognosis. The importance of left (LV) and right (RV) ventricular morphology and function in patients with end-stage lung diseases referred for lung transplantation (LT) is not well established., Objectives: To assess whether LV and RV echocardiographic parameters influence survival of patients with IPF, COPD and other interstitial lung diseases (ILD) awaiting LT., Methods: In 65 patients (20 patients with COPD, 37 with IPF and 8 with other ILD), we performed transthoracic echocardiography and right heart catheterization. Echocardiographic parameters were assessed with regard to 1-year all-cause mortality., Results: The mortality rate was higher in patients with smaller dimensions of LV end-systolic (LVESD) and end-diastolic (LVEDD) diameter (HR 3.03, 95% CI 1.16-7.69, P = .023; and HR 2.9, 95% CI 1.16-7.14, P = .022; respectively), higher RV-to-LV (RV/LV-4CH) ratio (HR 7.6, 95% CI 1.6-29.5, P = .009) and RV proximal outflow tract (RVOT-PLAX) dilatation (HR 2.69, 95% CI 1.22-5.96, P = .015). These associations were independent of age, gender, body mass index, VC, FEV1% and pulmonary diagnosis. The subanalysis of IPF patients demonstrated that the smaller LVESD and LVEDD increased mortality rate (HR 15.0, 95% CI 2.87-89.72, P = .003; HR 4.95, 95% CI 1.5-15.5, P = .006; respectively). No such associations were found in the COPD patients., Conclusion: LV echocardiographic parameters (LVESD or LVEDD) are useful in predicting survival in patients with end-stage lung diseases, mainly in IPF patients awaiting LT. Other parameters (RV/LV-4CH and RVOT-PLAX dilatation) may also influence survival., (© 2019 John Wiley & Sons Ltd.)

Background: Serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentration is elevated in patients with pulmonary hypertension (PH); however, its role in the detection of PH associated with lung disease is not well established., Aim: The aim of this study was to assess the value of NT-proBNP in the detection of PH in patients with end-stage lung disease (esLD) referred for lung transplantation., Materials and Methods: The study population consisted of 65 patients: 37 with idiopathic pulmonary fibrosis (IPF), 20 with chronic obstructive pulmonary disease, and 8 patients with other interstitial lung diseases (75% men, mean age 53.3 ± 9.5 years). Serum concentration of NT-proBNP was assessed with an immunoradiometric assay kit. The mean pulmonary artery pressure (mPAP) was measured using a Swan-Ganz catheter. PH was defined as mPAP ≥ 25 mm Hg., Results: Median NT-proBNP concentrations were significantly higher in patients with PH than in patients without PH: 139 (49-1236) pg/mL vs 67 (38-116) pg/mL, respectively; P = .016. Receiver operating characteristic (ROC) analysis revealed that NT-proBNP concentration higher than 131.5 pg/mL was a predictor of PH with good specificity (81%) and positive predictive value (78.9%) but low sensitivity (55.6%) and negative predictive value (58.6%). The area under the ROC curve of serum NT-proBNP concentration for PH was 0.71 (95% confidence interval 0.57-0.85, P = .039)., Conclusion: Serum concentration of NT-proBNP may be useful in the diagnosis of PH in patients with esLD referred for lung transplantation., (Copyright © 2018 Elsevier Inc.

Background: Pulmonary hypertension (PH) is a common complication in end-stage lung disease (esLD). The aim of this study was to establish the best threshold values for mean, systolic, and diastolic artery pressure (mPAP, dPAP, and sPAP, respectively) to identify patients with esLD referred for lung transplantation and to predict 1-year prognosis., Methods: Sixty-five patients were enrolled in the study (75% men) with a mean age of 53.3 ± 9.5 years; 31% had chronic obstructive pulmonary disease (COPD), 57% had idiopathic pulmonary fibrosis (IPF), and 12% had interstitial lung diseases (ILDs). The mean period of observation was 14.4 ± 5 months. We assessed invasively mPAP, dPAP, and sPAP, as well as pulmonary capillary wedge pressure (PCWP), using a Swan-Ganz catheter. Receiver-operating characteristic (ROC) curves were constructed to identify the best cutoff points for mPAP, dPAP, and sPAP to predict survival. The study endpoint was defined as 1-year mortality before transplantation. Survival analysis was completed according to the Kaplan-Meier method., Results: During follow-up, 30 (46.1%) patients died and 19 (29%) underwent lung transplantation. Based on ROC curve analysis, we estimated mPAP ≥30 mm Hg, dPAP ≥20 mm Hg, and sPAP ≥44 mm Hg as the best threshold values with the highest sensitivity (70%, 70%, and 73%, respectively) and specificity (76%, 69%, and 72%, respectively) and the acceptable area under curve (0.67, 0.68, and 0.72, respectively). The negative predictive values for mPAP, dPAP, and sPAP were higher than the positive predictive values (79%, 77%, and 81% vs 67%, 61%, and 64%, respectively). We also constructed Kaplan-Meier curves for mPAP, dPAP, and sPAP threshold values. There were significant differences in 1-year survival between patients with and without PH for mPAP, dPAP, and sPAP threshold values (P = .005, P = .035, and P < .001; respectively)., Conclusion: Elevated mPAP, dPAP, and sPAP are related to worse prognosis in patients with esLD referred for lung transplantation., (Copyright © 2018 Elsevier Inc.

Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension caused by alteration of pulmonary veins. Many clinical and hemodynamic similarities to idiopathic pulmonary arterial hypertension (IPAH) may cause diagnostic and therapeutic difficulties. This case report is about a patient with PVOD, whose first symptoms of the disease occurred after infectious mononucleosis. Patient was administered with prostacycline (PGI2) mimetic (Treprostinil), what made qualification process and lung transplantation possible. Despite more and more knowledge about causes, ethiopathogenesis and changes in pulmonary veins on molecular level, lung transplantation is the only successful therapeutic option for patients suffering from PVOD.

Background: In Poland, lung transplantation (LTx) as a routine method began in 2004, and since then, the Silesian Center for Heart Disease in Zabrze 85 LTx has performed (54 single-lung transplantations, 30 double-lung transplantations, and 1 heart-lung) transplantation. The recommendation to take vitamin supplements (without specific indication of the iodine content) does not apply to another iodine prophylaxis in patients after lung transplantation, excluding patients with known thyroid disease. The aim of this study was to assess thyroid gland function based on hormones and urinary iodine (UI) concentration in patients after LTx., Material and Methods: UI analysis was performed in 19 lung recipients (12 men and 7 women; mean age: 46.2 ± 12.47 years, BMI: 21 ± 2.25) and compared to TSH, free T3, and free T4., Results: Sufficient UI was observed only in 2 (9%) samples. In 12 samples (54.5%), mild iodine deficiency was recorded, in 4 samples (18.2%) moderate iodine deficiency was noted, and in 3 (13.6%) severe iodine deficiency was found. No correlation between BMI and UI, as well as hormones concentration, was observed. No correlation was revealed when analyzed samples were divided by patient sex., Conclusions: Although thyroid gland hormones were in the normal range, we found moderate, mild, and severe iodine deficiency in the majority of analyzed samples. Measurements of urinary iodine in lung transplant recipients should accompany thyroid hormone measurements as an iodine deficiency test and in order to prevent iodine deficiency disorders.

Introduction: The aim of this study was to assess peripheral blood lymphocyte subtypes (CD3+, CD19+, CD16+CD56+, CD4+, CD8+, and CD3+HLA-DR+) obtained from thoracic organ recipients at various periods after transplantation., Material and Methods: Seventeen patients after lung transplantation (LT) and 5 patients after heart transplantation (HT) included 13 males (76.5%) and 4 females (23.5%) of overall mean age at the time of transplantation of 46.7±11.55 years and mean body mass index of 21.1±4. Lymphocyte phenotypes were estimated using Simultest IMK Plus., Results: A significant decrease in lymphocytes of the majority of subtypes was observed at 1 year posttransplantation compared with normal ranges: CD19+ B lymphocytes in 56% of patients, CD8+ T cells among 48% and CD16+CD56+ natural killer elements, 56%. In contrast, there were increased numbers of activated lymphocytes (CD3+HLA-DR+). Beyond the 1-year observation, we observed a trend to normalize parameters among the majority of subjects., Conclusion: A clear tendency to a decrease number of peripheral blood lymphocytes of various subtypes was observed among thoracic organ recipients in the first year posttransplantation with the exception of activated HLA-DR+ cells. After the first year, there was slow restoration of lymphocytes., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Background: This publication attempted to evaluate the frequency of mold colonization and infection and the procalcitonin serum concentrations (PCT) among lung transplant recipients., Methods and Materials: We included 49 patients (36 males and 13 females) of mean age at transplantation of 47.1±13.6 years. Molds were isolated using routine microbiologic methods. PCT (ng/mL) was measured using an immunoluminescence assay with values below 0.5 showing no probability of infection, 0.5 to 2.0, a moderate infection risk; 2.0 to 10, a high infection risk; and above 10 high sepsis risk., Results: Twenty-four (49%) patients revealed the presence of molds in material from the lower respiratory tract (sputum, tracheal, or tracheobronchial aspirate), mini-bronchoalveolar lavage. Aspergillus species was isolated in 14 (28.6%) patients, Penicillium in 7 (14.3%) patients, and Zygomycetes fungi in 9 (18.4%) patients. The average PCT value from 61 examinations of PCT during fungal isolation was 0.5±0.7 ng/mL. However, when the studied group was categorized according to the PCT range, the rates for the groups were no infection (n=30; 49.2%), moderate (n=20; 32.8%), high (n=9; 14.8%) and high sepsis risk (n=2; 3.3%)., Conclusions: The mold colonization of transplanted lung is a frequent complication and should be considered even in the case of proper prophylaxis. Procalcitonin might be the marker helpful in mold infection diagnosis., (Copyright © 2011 Elsevier Inc. All rights reserved.)

Objective: Kidney injury represents a major clinical problem in orthotopic heart transplant (OHT) patients which seriously increases the mortality rate. The aim of this work was to evaluate the utility of a new kidney damage marker-neutrophil gelatinase-associated lipocalin (NGAL)-and its correlations with cystatin C, creatinine, and glomerular filtration rate (GFR) among patients after heart or lung transplantation., Materials and Methods: We examined serum samples from 71 patients after heart transplantation, 7 patients after lung transplantation, and 20 healthy controls to measure serum NGAL using an enzyme-linked immunosorbent assay (ELISA) method; cystatin C using latex immunonephelometry; and creatinine using the alkaline-picrate method., Results: Serum NGAL levels were significantly elevated among transplant patients, but did not significantly correlate with cystatin C in the transplant group (R = .13; P = .11) or in the control group (R = .26; P = .26), or GFR in the transplant group (R = -.09; P = .25) or in the control cohort (R = .22; P = .36). In the transplant group, serum NGAL positively correlated with serum creatinine (R = .27; P = .001)., Conclusions: Plasma NGAL was not a specific biomarker for monitoring chronic renal disorders. We did not exclude other pathologies that might contribute to increased serum NGAL levels.

Background: Lower respiratory tract infections remain a leading cause of morbidity and mortality after solid organ transplantation. The particularly increased susceptibility to infection is an especial problem in the early posttransplant period at the initial stage of immunosuppression, owing to direct contact with the hospital environment by mechanical ventilation, biopsies, injections, bronchoscopy, and bladder and vessel catheterizations exacerbated by the impaired clearance mechanisms after denervation of the transplanted lung. Airway colonization with Pseudomonas aeruginosa is common in lung transplant (LT) recipients. Therefore, we performed a retrospective analysis to address the frequency of P aeruginosa infections in our Center., Materials and Methods: From January 2004 to December 2008, we performed 33 LT, including 4 heart-lung, 6 double, and 23 single lung transplantations. Respiratory samples were the main diagnostic material undergoing routine microbiological methods., Results: P aeruginosa was isolated from 13 patients (39.4% of all 33 LT). In 10 cases (30.3%), we observed airway colonization together with lower respiratory tract infections. From 2005 to 2008, P aeruginosa was diagnosed in about 50% of LT patients each year: in 2005, 33.3%; 2006, 57.1%; 2007, 42.9%; and 2008, 40%., Conclusion: LT recipients in our center are at high risk for pseudomonal airway colonisation and lower respiratory tract infection that may have a significant impact on posttransplant follow-up.

Background: Allograft infection after lung transplantation (OLT) has a significant impact on outcomes and represents a diagnostic challenge. Pneumocystis jirovecii causes an opportunistic infection, life-threatening pneumonia among immunocompromised patients. Airway colonization with Pseudomonas aeruginosa is common in lung transplant recipients. The aim of the study was to evaluate procalcitonin (PCT) serum concentrations during P jiroveci and P aeruginosa colonization/infections in lung transplant recipients., Materials and Methods: Fifteen OLT patients were retrospectively enrolled into the study (10 men and 5 women) of overall mean age of 41.4 +/- 14.6 years. In seven patients, P jiroveci cysts were diagnosed (group J) and in 13 patients, we isolated P aeruginosa (group A). In respiratory samples, P jiroveci was detected using an indirect immunofluorescence method, and P aeruginosa was isolated using routine microbiologic methods. PCT was measured using immunoluminescence assay., Results: The average PCT value in group A was 0.30 +/- 0.21 and in group J, 0.88 +/- 0.43, a difference that was not significant. In group A, 3 patients (23.1%) has PCT values indicating moderate infection risk (PCT > 0.5) and one patient (7.7%), a high infection risk (PCT > 2.0 and <10). In group J, three patients (42.9%) has PCT values indicating moderate and one patient (14.3%), high infection risk., Conclusions: Bronchial tree colonization with P jiroveci as well as P aeruginosa colonization can be associated with increased PCT suggesting a general, systemic response in addition to local colonization.

Background: Single lung transplantation, bilateral lung transplantation and combined heart-lung transplantation are the procedures currently being performed in patients with arterial pulmonary hypertension and pulmonary hypertension as a result of end-stage lung disease. In patients with severe pulmonary hypertension, regardless of its aetiology, general anaesthesia and mechanical ventilation could precipitate the onset of cardiac failure and the necessity of extracorporeal circulation employment., Aim: To assess the clinical and prognostic value of the pulmonary artery pressure (PAP) measured during the intra- and early postoperative period in patients undergoing lung transplantation., Methods: We analysed 20 patients undergoing lung transplantation in the Silesian Centre for Heart Disease in Zabrze, of whom 13 suffered from pulmonary hypertension before the operation. The PAP was measured using Swan-Ganz catheters., Results: Pulmonary artery pressure markedly decreased after transplantation (systolic, diastolic and mean PAP values were 31/19/23 mmHg, respectively) but in 3 recipients the mean PAP exceeded 25 mmHg (45/23/30 mmHg). In all 3 cases a cardiopulmonary bypass was required and single-lung transplantation was performed. Pulmonary hypertension immediately after the operation was the potential marker of lung dysfunction (pulmonary oedema, ischaemia-reperfusion injury, infection) - all 3 patients with increased PAP developed complications., Conclusions: Lung transplantation is associated with a significant reduction in pulmonary artery pressures immediately after graft implantation. The persistence of pulmonary hypertension in the early postoperative period suggests temporal allograft dysfunction and affects the post-operative outcome.

The objective of this study was to determine the prevalence of left ventricular (LV) dysfunction in patients with advanced interstitial lung disease (ILD) and the relationship between LV function and factors limiting physical activity. In 2005-2006, 40 patients with end stage ILD were admitted with qualifications for lung transplantation (LT). From this group, 18 patients (7 women, 11 men) were referred for LT (active list), 22 patients (8 women, 14 men), who did not meet the ATS/ERS criteria for LT were excluded from this procedure (waiting list). All patients had echocardiography, spirometry, 6-min walking test (6MW), and gas exchange measurements. The following main echocariographic data that describe the LV function and morphology were taken into account: LVs, LVd, LVPWd, LVPWs, Ao, LA, ESV, EDV, and EF. We noted significant differences in LVPWd (P=0.01), ESV (P=0.01), and EDV (P=0.02), which presented lower values in patients on the active list compared with those on the waiting list. A positive correlation was found between 6MW and LVs (r=0.41), LA (r=0.45), ESV (r=0.62), and EDV (r=0.68). Correlations between spirometric, gas exchange, and left ventricle echocardiographic data were also observed. We conclude that patients on active list for lung transplantation present a decrease in the diameter and volume of the left ventricle. The latter change may influence the functional ability of interstitial lung disease patients.

The aim of the study was to identify prognostic factors that would differentiate patients with interstitial lung disease between those with and without a chance to survive until lung transplantation. A retrospective study was performed in patients with interstitial lung disease referred for lung transplantation between September 1999 and April 2005. The analysis included the demographic data, the time from referral to transplantation, the functional tests (FVC, FEV1, FEV1%VC, the PaO(2) at rest and after oxygen supplementation via a nasal catheter), the count of NYHA functional classes, the left ventricular ejection fraction (EF), the distance covered during a 6-min walk test, and the pathogens in the respiratory tract. The patients were divided into two groups: Group 1 - lung transplant candidates who survived until the successful procedure and Group 2 - lung transplant candidates who died while on the waiting list. There were statistical differences between the two groups in PaO2 after supplementation (P=0.005), EF (P=0.002), and the 6-min walk distance (P=0.001). It appears that simple functional tests of the cardiorespiratory system may define survival of patients with interstitial lung disease waiting for lung transplantation.

Until the year 2001, lung transplantation was not available in Poland, as the only one among other kinds of solid organs transplantation. In 2001, in the Silesian Center for Heart Diseases the first successful combined heart-lung-one-block transplantation was performed. In 2003 and 2004, a successful single lung transplantation in Poland was performed in our center. Here the authors presented their experience with lung transplantation including the indications for specific types of transplantation, the immunosuppressive regimen, the management of early and late stages after lung transplantation, the infection complications, and the current problems with lung transplantation progress.

Lung transplantation is now generally accepted as a modality of care for patients with end-stage lung diseases who demonstrate declining of lung function despite optimal therapy. This paper describe a case of single lung transplantation performed in patient with advanced obstructive pulmonary diseases and pulmonary fibrosis. One year follow-up with special regard to complications after operation is presented.
