As the aging proceeds worldwide, aging lung transplantation recipients have been increased dramatically. Aging population with end-stage lung diseases also have comorbidities, such as cardiovascular disease, which may impact the prognosis of lung transplantation. Recent researches on lung transplantation have explored the characteristics of aging recipients, strategy selection on transplantation and cardiovascular disease management, as well as risk factors for post-transplantation complications and death. However, researches on lung transplantation recipients with cardiac valve disease are just in the initial stage. With the advancement of transcatheter technique, more patients will be benefited. We summarized the advancement in this field and took an outlook for future clinical researches.
With the deepening of current study and the innovation of perioperative management concept, there have been great advances in lung transplantation in recent years. The prognosis of patients has been significantly improved. At the same time, the role of various types of blood purification in the clinical monitoring and treatment of lung transplant patients is becoming increasingly prominent. This review aims to summarize the application and latest progress of in vitro blood purification such as renal replacement therapy, plasmapheresis and hemadsorption in the perioperative period of lung transplantation, and to provide a basis for further study.
Objective To compare outcomes after single versus bilateral lung transplantation in patients with end-stage chronic obstructive pulmonary disease (COPD) with retrospective cohort study, and to provide a reference for surgical selection. Methods One hundred and two patients with end-stage COPD who received lung transplantation in Wuxi People's Hospital affiliated to Nanjing Medical University from January 2010 to May 2019 were evaluated, including 97 males and 5 females, aged from 42 to 82 years, with an average age of (59.8±8.0) years. Recipients were divided into single lung transplantation (SLT) group (31 cases) and bilateral lung transplantation (BLT) group (71 cases). Preoperative characteristics, postoperative outcomes, postoperative complications, functional improvement and survival between the two groups were analyzed retrospectively. Results The SLT group were significantly older than the BLT group [(62.6±8.8) years vs. (58.6±7.4) years, P<0.05], which was consistent with the practice mode of single lung transplantation in the elderly patients in this center. The FEV1% predicted and the six‐minute walk distance (6-MWD) in the BLT group were better than those in the SLT group (P<0.05). The cumulative survival rate in 1, 3 and 5 years after operation in the BLT group was higher than that in the SLT group (70.4%, 63.2%, 61.5%, respectively vs. 67.7%, 58.1%, 54.6%, respectively), but there was no statistical difference (P=0.388). The two groups were comparable in other preoperative clinical data (P>0.05). The cold ischemia time and total operation time were shorter in the SLT group than in the BLT group, and the intraoperative blood loss was less than that in the BLT group, but more patients required intraoperative extracorporeal membrane oxygenation support than the BLT group (P<0.05). There were no significant differences in postoperative ventilator support, reoperation, length of intensive care unit stay, postoperative hospital stay, and perioperative mortality (P>0.05). In terms of postoperative complications, the incidence of primary graft dysfunction grades 3 was higher in the SLT group than in the BLT group (35% vs. 8%, P=0.001). There were no significant differences between the two groups in chest complications, airway complications, acute rejection, infection, and bronchial occlusion syndrome (P>0.05). Nine patients (29%) developed acute native lung hyperinflation in the SLT group. ConclusionsBilateral lung transplantation is superior to single lung transplantation in the treatment of end-stage COPD. The advantage is mainly reflected in the simple perioperative management, better functional improvement after operation. Single lung transplantation as a beneficial supplement to double lung transplantation should still be considered in selected patients.
Objective To investigate the experience of operative technique of donor organ harvesting and lung transplantation in some unusual circumstance, and to improve surgical success ratio of lung transplantation. Methods Lung transplants were preformed in 65 cases, including 47 singlelung transplants and 18 double single lung transplants. All the recipients were suffered from intensive respiratory failure,and nine patients were longterm ventilatordependented of the total. The recipients included emphysema (n=23), pulmonary fibrosis (n=24), pneumosilicosis(n=5), pulmonary tuberculosis(n=2), lymphangioleiomyomatosis(n=1) and ventricular septal defect(VSD) or VSD with Eisenmenger’s syndrome(n=4),bronchiectasis (n=4), diffuse panbronchiolitis (n=1) and primary pulmonary hypertension(n=1). Retrospectively summarize clinical experience of lung transplant operation especially experience of dealing with special circumstances encountered in operation. Results 64 donor organ harvesting were achieved successfully. Inhospital death was 11cases (16.9%) after operation. Early death was due to primary lung graft dysfunction (n=3), severe infection(n=6), acute rejection(n=1), pulmonary vein embolism(n=1). Complications took place after operation in 9 cases, to exploratory thoracotomy to stop bleeding after transplantation in 3 cases, pulmonary artery anastomosis again because of stenosis in 1 case, bronchus stoma stenosis in 3 cases, pulmonary infarction in 2 cases, of which one patient accepted pulmonary lobectomy. Follow-up period was from 1.0 year to 5.6 years of 54 cases. 1year survival rate was 72.3%（47/65）.The pulmonary function was improved and the quality of life is well in most patients of the group. Conclusion To improve the technique of donor organ harvesting and lung transplantation is important to decrease the early mortality after transplantation.
Objective To identify and analyze risk factors for acute renal failure (ARF) following lung transplantation and to develop a predictive model. Methods Data for this study were obtained from the United Network for Organ Sharing (UNOS) database, encompassing patients who underwent unilateral or bilateral lung transplantation between 2015 and 2022. We analyzed both preoperative and postoperative clinical characteristics of the patients. A combined approach utilizing random forest and least absolute shrinkage and selection operator (LASSO) regression was employed to identify key factors associated with the incidence of ARF post-transplantation, based on which a nomogram model was developed. The predictive performance of the constructed model was evaluated in both training and validation sets, using receiver operating characteristic (ROC) curves and area under the curve (AUC) metrics to verify and compare model effectiveness. ResultsA total of 15 110 lung transplantation patients were included in the study, consisting of6 041 males and 9 069 females, with a median age of 62.00 years (interquartile range: 54.00 to 67.00). The analysis revealed statistically significant differences between postoperative renal dialysis and non-dialysis patients regarding preoperative lung diagnosis, estimated glomerular filtration rate (eGFR), mechanical ventilation, preoperative ICU treatment, extracorporeal membrane oxygenation (ECMO) support, infections occurring within two weeks prior to transplantation, Karnofsky Performance Status (KPS) score, waitlist duration, double-lung transplantation, and ischemia time (P<0.05). Five key variables associated with ARF after lung transplantation were identified through random forest and LASSO regression: recipients’ eGFR, preoperative ICU treatment, ECMO support, bilateral lung transplantation, and ischemia time. A nomogram model was subsequently established. Model evaluation demonstrated that the constructed predictive model achieved high accuracy in both training and validation sets, with favorable AUC values, confirming its validity and reliability. ConclusionThis study identifies common risk factors for ARF following lung transplantation and introduces an effective predictive model with potential clinical applications.
Objective To establish a simple, valid rat orthotopic left lung transplantation model with the improved operation technique. Methods One hundred and thirty-six male SD rats were randomly divided into donor （n = 68） and recipient （n = 68）, transplantation were performed by using the improved cuff anastomosis technique. Results Time of donor lung perfusion-picking, donor lung vessel cuff anastomosis and recipient vessel anastomosis was 13±2 min, 9±1 min, 10±1 min respectively, the operative time was 60±3 min. In 68 rats of operations, successful rate was 88%（60/68）, anastomotic stoma leak in one rat, lung congestion 3 rats, lung atelectasis 4 rats. The shortest survival time was 1 day, there were 53 rats whose survival time was longer than 12 days. The chest computed tomography showed no atelectasis and blood gas analysis manifested good respiratory function. Conclusion The improved three cuff anastomosis technique offers a simple, valid, cheap and useful method,it can establish rat orthotopic left lung transplantation model successfully.
Lung cancer is the most prevalent malignant tumor worldwide. For lung cancer patients with multiple intrapulmonary metastases or impaired lung function, complete tumor resection is challenging, and the prognosis is poor. Lung transplantation demonstrates potential therapeutic value in achieving complete tumor resection, improving lung function, and enhancing quality of life. Advances in tumor detection technologies such as positron emission tomography-computed tomography and circulating tumor DNA, along with the development of comprehensive treatment strategies for lung cancer, provide powerful tools for accurately predicting tumor recurrence and treatment outcomes following lung transplantation. The feasibility of lung transplantation as a treatment for lung cancer is receiving increasing attention. This article reviews the history and clinical management of lung transplantation for lung cancer.
ObjectiveTo explore the clinical value of next-generation sequencing (NGS) in the diagnosis of Pneumocystis jirovecii pneumonia (PCP).MethodsTwo patients with Pneumocystis jirovecii pneumonia after lung transplantation were detected by NGS in the sputum and bronchoalveolar lavage fluid. The clinical data, imaging features, laboratory examination and treatment of the two patients were reported. A systematic literature review was performed for similar published cases in PubMed database, using the keywords "lung transplantation/solid organ transplantation" and "Pneumocystis jirovecii".ResultsThere were six references based on the keywords of "lung transplantation " and " Pneumocystis jirovecii ", of which three were case report. Sixty-six lung transplant patients were complicated with Pneumocystis jirovecii in total. The clinical manifestations of Pneumocystis jirovecii pneumonia were fever and dyspnea of different degrees. The diffuse "ground glass" infiltration could be shown on imaging. Computer tomography scan of chest was a sensitive method to detect PCP. Combined immunofluorescence microscope/PCR/serum 3-β-D-glucan could effectively improve the accuracy of microbiology detection. In addition, NGS could quickly and accurately identify pathogenic bacteria, give guidance for treatment and improve prognosis so as to benefit patients well. Trimethoprim/sulfamethoxazole (TMP/SMZ) was the preferred choice for the treatment of PCP patients.ConclusionsPneumocystis jirovecii pneumonia is more common in patients with immunodeficiency or immunosuppression. NGS can help rapid and accurate diagnosis, and the treatment should be early and sufficient.
Abstract: Objective To evaluate the clinical effects and health economics of lung volume reduction surgery（LVRS）, single lung transplantation（SLTx） and bilateral lung transplantation（BLTx） for patients with end-stage emphysema. Methods A total of 61 patients with end-stage emphysema, including 39 patients who underwent LVRS（LVRS group）, 14 patients who underwent SLTx（SLTx group）, and 8 patients who underwent BLTx（BLTx group） from September 2002 to August 2008 in Wuxi People’s Hospital, were analyzed retrospectively. Lung function, arterial blood gas analysis and 6-minute walk distance（6-MWD）were assessed before their surgery and 6 months, 1-year and 3-year after their surgery respectively. Their 1-year and 3-year survival rates were observed. Cost-effectiveness analyses were made from a health economics perspective. Results Compared with their preoperative results, their mean forced expiratory volume in 1 second（FEV1.0）in LVRS group increased by 75%, 83% and 49% at 6 months, 1-year and 3-year postoperatively, by 176%, 162% and 100% in SLTx group, and by 260%, 280% and 198% in BLTx group respectively. Their mean forced vital capacity（FVC）in LVRS group increased by 21%, 41% and 40% at 6 months, 1-year and 3-year postoperatively, by 68% , 73% and 55% in SLTx group, and by 82%, 79% and 89% in BLTx group respectively. Their exercise endurance as measured by 6-MWD increased by 75%, 136% and 111% in LVRS group at 6 months, 1-year and 3-year postoperatively, by 513%, 677% and 608% in SLTx group, and by 762%, 880% and 741% in BLTx group respectively. The 1-year and 3-year survival rates after operation were 74.40% and 58.90% in LVRS group, 85.80% and 64.30% in SLTxgroup, and 62.50% and 50.00% in BLTx group respectively. The three years’ cost utility of SLTx group was significantly higher than that of BLTx group（1 668.00 vs.1 168.55, P＜ 0.05）and LVRS group （1 668.00 vs. 549.46, P＜ 0.05）. Conclusion SLTx and BLTx are better than LVRS in improving patients’ lung function and exercise endurance for end-stage emphysema patients. LVRS is more cost-effective than SLTx and BLTx in the early postoperative period. With the development of medical technology and decreased expenses of lung transplantation and immunosuppressive agents, lung transplantation will become the first surgical choice for end-stage emphysema patients.
