ABSTRACT

BACKGROUND: On February 6, 2023, an earthquake in Türkiye caused massive destruction. Over 50.000 people are known to have lost their lives, and over 100.000 are known to have been maimed. In our study, we aimed to analyze the treatment process of 267 METHODS: The demographic characteristics, the time spent under the rubble, the duration of transfer to the hospital, and the treatment process of patients admitted to our hospital have been evaluated. RESULTS: There are 125 (46.8%) men and 142 (53.2%) women in the study. The rate of thoracic trauma was 21.8%. Of all the patients, 15.7% (n=42) had pneumothorax, 18% (n=48) had contusion, 28.8% (n=77) had hemothorax, and 73% (n=195) had rib fractures. The mean time spent under the rubble was 17.6±26.5 h, the duration of transfer to the hospital was 138.5±113.6 h, and the hospitalization time was 93.8±152.3 h. The duration of hospitalization and transfer has been statistically longer for the patients who were under the rubble (85.4%) than for those who were not. (14.6%) (p=0.048). There is a statistically weak positive correlation between the time spent under the rubble and the time of transfer (p=0.048). CONCLUSION: The state, the time spent under the rubble, and the presence of hemothorax and pneumothorax should be effectively evaluated in earthquake-induced thoracic traumas. Considering these criteria in the transfer of patients to the centers operating at full capacity in a short time will minimize morbidity and mortality.

ABSTRACT

Introduction: Chronic obstructive pulmonary disease is a progressive airway disease that can progress to the terminal stage requiring oxygen supply. In this period, lung volume reduction therapies and/or lung transplantation may be considered. Morbidity and mortality risks due to transplant surgery and posttransplant immunosuppressive therapy show the importance of selecting the best candidates who will benefit from transplantation. In this context, BODE index criteria serve as important markers. This study aimed to analyze the outcomes of lung transplantation in patients with chronic obstructive pulmonary disease and to identify variables that may affect post-transplant clinical outcomes. Materials and Methods: Lung transplants diagnosed with chronic obstructive pulmonary disease performed in our center between March 2013 and January 2023 were included in the study. Demographic information and both pre-op and post-op clinical data of the transplant patients were collected. The effect of BODE index criteria and other pre-transplant clinical data on short- and long-term outcomes after transplantation were investigated. Results: During the study period, 34 lung transplants were performed for chronic obstructive pulmonary disease. One patient died during the operation, three patients received single transplants, and 30 received double transplants. Post-operative primary graft dysfunction was more common in single transplant recipients. The results were comparable between single and double transplants in terms of post-transplant pulmonary function and the development of chronic lung allograft dysfunction. BODE index criteria had no effect on early and late post-operative clinical data, however intra-operative use of extracorporeal membrane oxygenation, primary graft dysfunction, and prolonged extubation were significantly higher in recipients younger than 60 years. Conclusion: Our study suggests that prelisting demographic and clinical data of chronic obstructive pulmonary disease patients had no significant effect on post-operative outcomes, however, intra-operative ECMO use, prolonged extubation, primary graft dysfunction (p< 0.05 for each) and chronic rejection (p> 0.05) were more common in patients who are <60 years of age. These data need to be confirmed by larger studies.

ABSTRACT

INTRODUCTION: Myxofibrosarcoma usually occurs in the extremities of middle-aged to older adults. Metastatic myxofibrosarcomas generally emerge in the lung. In this case report, we aim to present a case of primary pulmonary myxofibrosarcoma with tumor thrombus extending into the left atrium without pulmonary vein or atrial invasion. CASE PRESENTATION: A 55-year-old male who was being followed up due to a pulmonary nodule presented with a mass extending from the left lower lobe to the left atrium. No extrathoracic malignancy was detected in the pre-operative examination. The mass extending into the left atrium without invasion was excised with the lower lobe of the left lung. A post-operative histopathological examination revealed myxofibrosarcoma. CONCLUSION: Very few cases of cervical, thoracic wall, mediastinum and cardiac primary myxofibrosarcoma have been documented, and to the best of our knowledge, only one primary pulmonary myxofibrosarcoma case has previously been reported in the English literature. Here, we present a case of primary pulmonary myxofibrosarcoma that extended to the left atrium through the pulmonary vein. In such rare clinical presentations, intracardiac tumor resection should precede pulmonary resection due to the possibility of catastrophic tumor embolisms.

ABSTRACT

OBJECTIVE: The transplantation waiting list is getting longer day by day with the spread of lung transplantation and awareness of it. However, the donor pool cannot keep up with this rate. Therefore, nonstandard (marginal) donors are widely used. By studying the lung donors presented at our center, we aimed to raise awareness of the donor shortage and compare clinical outcomes in recipients with standard and marginal donors. MATERIALS AND METHODS: The data from recipients and donors of lung transplants performed at our center between March 2013 and November 2022 were retrospectively reviewed and recorded. Transplants with ideal and standard donors were classified as group 1, and those with marginal donors were classified as group 2. Primary graft dysfunction rates, intensive care unit, and hospital stay days were compared. RESULTS: Eighty-nine lung transplants were performed. A total of 46 recipients were in group 1 and 43 were in group 2. There were no differences between groups in the development of stage 3 primary graft dysfunction. However, a significant difference was found in the marginal group for developing any stage primary graft dysfunction. Donors were mostly from the western and southern regions of the country and from the education and research hospitals. CONCLUSION: Because of the donor shortage in lung transplantation, transplant teams tend to use marginal donors. Stimulating and supportive education for healthcare professionals to recognize brain death and public education to raise awareness about organ donation are necessary to spread organ donation throughout the country. Although our results using marginal donors are similar with the standard group, each recipient and donor should be assessed individually.

ABSTRACT

OBJECTIVES: In this study, we investigated dynamic thiol-disulfide homeostasis as a new indicator of oxidative stress in lung transplant recipients. In addition, we compared dynamic thiol-disulfide homeostasis parameters according to transplant indication and time after transplant. MATERIALS AND METHODS: This study had a single-center, observational, randomized design. In terms of transplant indications, lung transplant recipients were grouped as chronic obstructive pulmonary disease, interstitial lung disease, bronchiectasis, and other indications. To make comparisons based on time after transplant, lung transplant recipients were categorized into the following groups: >6 and ≤24 months, >24 and ≤48 months, >48 and ≤72 months, and >72 months. A fully automated spectrophotometric technique was used to measure dynamic thiol-disulfide homeostasis in fasting blood samples. RESULTS: Our study included 34 lung transplant recipients and 36 healthy volunteers. Native thiol (P = .005) and total thiol levels (P = .06) were lower in lung transplant recipients. Disulfide levels were similar. Disulfide-to-native thiol (P = .027) and disulfide-to-total thiol ratios (P = .027) were significantly higher in lung transplant recipients. Native thiol-to-total thiol ratios were lower in lung transplant recipients (P = .027). When we examined patients according to transplant indication, no statistically significant differences were found in dynamic thiol-disulfide homeostasis parameters, except for total thiol and disulfide levels. We also found no significant differences when we examined dynamic thiol-disulfide homeostasis parameters according to time after transplant. CONCLUSIONS: Thiol-related antioxidant activity is significantly reduced after lung transplant, regardless of indication and transplant time. Ensuring oxidative balance in lung transplant recipients with an antioxidant supplement regimen can prevent damage from oxidative stress.

ABSTRACT

OBJECTIVES: The effectiveness of COVID-19 vaccines in lung transplant recipients is unclear. We retrospectively analyzed lung transplant recipients vaccinated with an inactivated virus vaccine (CoronaVac) and the mRNA vaccine BNT162b2 used against the SARS-CoV-2 virus in Turkey and shared their effects on COVID-19. MATERIALS AND METHODS: Demographic data of lung transplant recipients followed up for >3 months were collected, and vaccination dates and status against the SARS-CoV-2 virus were recorded. Recipients who received at least 3 doses of CoronaVac or 2 doses of BNT162b2, or 1 dose of CoronaVac plus 2 doses of BNT162b2, or 2 doses of CoronaVac plus 1 dose of BNT162b2 were considered fully vaccinated; those who were vaccinated less than this number were considered partially vaccinated. Patients with positive SARS-CoV-2 reverse transcription-polymerase chain reaction tests from respiratory tract samples were accepted as positive for COVID-19. Recipients were classified by number and type of vaccine, and groups were compared for infection, need for intensive care, and death as a result of COVID-19. RESULTS: Of the 53 lung transplant recipients, 51 were vaccinated (7 partially vaccinated, 44 fully vaccinated) and 2 were not vaccinated. Of fully vaccinated recipients, 13/44 received the inactivated vaccine, 5/44 received the mRNA vaccine, and 26/44 had a combination of the 2 vaccines. During the follow-up period, 13 patients (2/2 not vaccinated, 2/7 [28.5%] partially vaccinated, 9/44 [20.5%] fully vaccinated) were diagnosed with COVID-19. There was no significant difference in protection against infection between the inactivated, the mRNA, and combined vaccine groups. There was no significant association in cycle threshold values that determine the infection load and COVID-19 severity between transplant recipients who died and those who did not. CONCLUSIONS: In lung transplant recipients, 3 doses of inactivated vaccine, 2 doses of mRNA vaccine, or the combined heterologous vaccine provided similar protection. Prevention of exposure is one of the most crucial steps.

ABSTRACT

OBJECTIVES: Oxidative stress developing due to oxidant/antioxidant imbalance plays a crucial role in the etiopathogenesis of chronic progressive lung diseases.The condition is typically more severe in lung transplant candidates with end-stage lung disease. Here, we investigated dynamic thiol-disulfide homeostasis as a marker for oxidative stress in lung transplant candidates. MATERIALS AND METHODS: The study included 40 patients with end-stage lung disease with indications for lung transplant (candidate group) and 40 healthy controls. Patient demographic data, laboratory results, and thiol-disulfide homeostasis values were recorded. We categorized patients according to their primary diseases and noted clinical measurements of forced expiratory volume in 1 second, forced vital capacity, 6-minute walk test, systolic pulmonary artery pressure, and lung allocation scores.Thiol-disulfide homeostasis parameters were compared before and after transplant. RESULTS: Demographic characteristics were similar in the candidate and control groups. In the candidate group, native thiol and total thiol levels (antioxidant parameters of thiol-disulfide homeostasis) were significantly lower, whereas disulfide-to-native thiol and disulfide-to-total thiol ratios (oxidant parameters of thiol-disulfide homeostasis) were significantly higher. We observed no significant differences between the disease subgroups in terms of thioldisulfide homeostasis parameters. Moderately significant correlations were shown between the antioxidant markers ofthiol-disulfide homeostasis and the clinical measurements, including the lung allocation scores. Our multiple regression analyses showed that native thiol and total thiol were significant predictive factors to estimate the lung allocation score. During the study period, 6 patients (15%)received lung transplant. There were significant differences in antioxidant parameters ofthiol-disulfide homeostasis in the pre- versus posttransplant periods. CONCLUSIONS: In patients with end-stage lung disease, the dynamic thiol-disulfide homeostasis status is altered in favor of oxidants. Thus, thiol-disulfide homeostasis parameters can be used to detect oxidative stress and estimate lung allocation scores in these patients. Lung transplant may have positive effects on oxidative stress.

ABSTRACT

Silicosis, a progressive, fibrotic occupational lung disease with no known treatment, is an uncommon indication for lung transplant. There is a paucity of research on patients with silicosis who have received lung transplants. The long-term consequences of the native lung in patients with severe chronic silicosis who have had a single-lung transplant are also of interest. We present a case of amyloidosis in a patient who underwent a single-lung transplant for silicosis.

ABSTRACT

BACKGROUND: Most lung transplantation centers prefer triple immunosuppressive therapy with tacrolimus, mycophenolate mofetil, and corticosteroids. However, to prevent complications and comorbidities caused by tacrolimus, replacing the drug with everolimus has been considered. METHODS: This is a retrospective observational study investigating everolimus switch for different reasons. The population was divided into 3 groups: chronic lung allograft dysfunction (CLAD), kidney impairment, and malignant neoplasm groups. We investigated whether we achieved the goal of the switch and the frequency of rejection, cytomegalovirus and fungal infections, and everolimus adverse effects. RESULTS: Nineteen patients received everolimus therapy, and 5 of these were for CLAD, 7 for tacrolimus nephrotoxicity, and 7 for explant/de novo malignant neoplasm. The patients were followed up for a mean (SD) of 30 (16.7) months under the therapy. The number of acute cellular rejection, cytomegalovirus infection, and aspergillosis infection cases before switch were 7, 13, and 2, respectively, and 7, 2, and 3 after that. The mean values of creatinine and estimated glomerular filtration rate of the whole population after the switch improved with no statistical significance, whereas it was significant in tacrolimus nephrotoxicity group. Three patients in the CLAD group remained stable after switching, whereas 2 progressed. Only 1 of the 7 patients with malignant neoplasms had a recurrence during 31.1 (16.5) months of median follow-up. Eleven cases of everolimus adverse effects occurred in 9 patients (47.3%), with 2 (10.5%) withdrawal events. Kidney impairment (P = .02) and age (P = .05) stood out as significant risk factors for drug adverse effects. CONCLUSIONS: After lung transplant, everolimus can be a safe alternative for immunosuppression with acceptable adverse effects.

ABSTRACT

Management of tracheal complications due to endotracheal intubation in patients with coronavirus disease-2019 (COVID-19) is an important concern. This study aimed to present the results of patients who had undergone tracheal resection and reconstruction due to COVID-19-related complex post-intubation tracheal stenosis (PITS). We evaluated 15 patients who underwent tracheal resection and reconstruction due to complex PITS between March 2020 and April 2021 in a single center. Seven patients (46.6%) who underwent endotracheal intubation due to the COVID-19 constituted the COVID-19 group, and the remaining 8 patients (53.4%) constituted the non-COVID-19 group. We analyzed the patients' presenting symptoms, time to onset of symptoms, radiological and bronchoscopic features of stenosis, bronchoscopic intervention history, length of the resected tracheal segment, postoperative complications, length of hospital stay, and duration of follow-up. Six of the patients (40%) were female, and 9 (60%) were male. Mean age was 43.3 ± 20.5. We found no statistically significant difference between the COVID-19 and non-COVID-19 PITS groups in terms of presenting symptoms, time to onset of symptoms, stenosis location, stenosis severity, length of the stenotic segment, number of bronchoscopic dilatation sessions, dilatation time intervals, length of the resected tracheal segment, postoperative complications, and length of postoperative hospital stay. Endotracheal intubation duration was longer in the COVID-19 group than non-COVID-19 group (mean ± SD: 21.0 ± 4.04, 12.0 ± 1.15 days, respectively). Tracheal resection and reconstruction can be performed safely and successfully in COVID-19 patients with complex PITS. Comprehensive preoperative examination, appropriate selection of surgery technique, and close postoperative follow-up have favorable results.

ABSTRACT

Background: This study aims to evaluate the results of the method we used to treat sternal dehiscence and mediastinitis due to median sternotomy following open heart surgery. Methods: Between July 2014 and March 2019, a total of 13 patients (8 males, 5 females; mean age: 60.3±2.9 years; range, 33 to 74 years) who underwent sternal reconstruction procedure and developed sternal dehiscence and mediastinitis after cardiac surgery were retrospectively analyzed. Data of the patients were retrieved from the hospital records. Results: Before the procedure, reconstruction was performed by using the Robiscek technique in three cases and a conventional rewiring technique was used in one case. Except for one case, all the other cases had sternal purulent discharge (n=12, 92%). Except for four cases, all cases had at least two fracture lines in the sternum (n=9, 69%). One to 10 sessions of (median=4) vacuum-assisted closure therapy were used in cases before the procedure. At least two bars were placed between the opposite ribs for sternal fixation. Except for three cases, all of the cases were placed transdiaphragmatic harvested omentum in the sternal cavity. Seroma and local infection recurrence occurred in two cases (n=2, 15.3%) and incisional hernia in one case (n=1, 7.6%). Thoracic stabilization was successfully achieved in all cases. Conclusion: Thoracic stabilization can be successfully achieved in complicated sternal dehiscence cases with sternal reconstruction with STRATOS system supported by vacuum-assisted closure therapy, until the culture turns negative in the preoperative period and by the use of transdiaphragmatic omentum intraoperatively inside the sternal cavity.

ABSTRACT

Segmental nonanastomotic stenosis, also known as vanishing bronchus intermedius syndrome (or simply, "vanishing bronchus"), is a rare complication that can occur after a lung transplant. It usually occurs in the first posttransplant year and often develops in the intermediate bronchus. Definitive diagnosis is established by bronchoscopy. The treatment management primarily includes bronchoscopic dilatation and stenting. In patients who do not benefit from these applications, lung resection or retransplant may be indicated. Our 58-year-old patient developed vanishing bronchus after lung transplant, and recurrence could not be prevented despite repeated bronchoscopic interventions. We applied submucosal mitomycin C injection to the bronchial wall of the stenotic segment and achieved significant benefit for reduction of recurrence. Our aim was to document the first reported case of a patient with vanishing bronchus who was treated with submucosal administration of mitomycin C, a strong fibroblast inhibitor, and to report the outcomes of submucosal mitomycin C administration with regard to recurrence.

ABSTRACT

OBJECTIVES: The COVID-19 pandemic, which emerged in late 2019, adversely affected all solid-organ transplant processes. Here we share the donor presentations evaluated in a lung transplant center during the COVID-19 pandemic,the measures taken at every stage of transplant management, and the outcomes of our transplants. MATERIALS AND METHODS: Data from 15 lung donors selected by the national coordination center presented to our lung transplant center as of March 11, 2020, when the first COVID-19 case was reported in Turkey, and data of 5 lung transplant cases in this period were retrospectively analyzed. All donors were examined in detail for COVID-19 disease. Procurement processes for accepted donors,transplant surgeries of recipients, and postoperative follow-up and care processes of recipients were carried out with the least number of personnel, but all with appropriate personal protective equipment. RESULTS: There were 15 donor organs procured by our center during a 9-month period coincident with the COVID-19 pandemic. The number of donor presentations to our center between the same dates in the previous year was 78. Five of the 15 donors were accepted, and of those accepted, 4 were male and 1 was female. There was no statistically significant difference between the accepted and rejected donors in terms of the ratio of Pao2 to fraction of inspired oxygen, age, duration of endotracheal intubation (days), and smoking (pack-years). All SARS-CoV-2 reverse transcription-polymerase chain reaction tests performed on bronchoalveolar lavage samples and nasopharyngeal, conjunctival, and rectal samples collected from the recipients during the follow-up period were negative. No pathological finding suggestive of COVID-19 infection was noted in the radiological evaluations. CONCLUSIONS: Lung transplant can be successfully managed during the COVID-19 pandemic period, despite the high risk of infection.The major obstacle to the continuity of lung transplantin this period was the limited number of donors.

ABSTRACT

BACKGROUND: Benign tracheal stenosis is a common complication in patients followed up in intensive care units. We aimed to analyze the etiology, diagnostic approaches, treatment methods for benign tracheal stenosis, and the predicting factors for complications after tracheal resection for benign stenosis. MATERIAL-METHOD: Forty patients who underwent tracheal resection reconstruction due to benign tracheal stenosis were analyzed retrospectively. Predictive factors for complications were determined by statistical analysis. RESULTS: There were 23 patients (57.5%) in the intubation group, 11 patients (27.5%) in the tracheostomy group, and 6 patients (15%) in the subsequent tracheostomy group. Preoperatively, rigid dilatation was applied to all patients between 2 and 6 sessions (median = 3). Tracheal resections were performed in all patients after rigid dilatations. The mean of the resected segment lengths is 32.1 ± 8.8 mm. There was a statistically significant difference between preoperative bronchoscopic measurements, preoperative tomography measurements, and intraoperative measurements of the stenosis segment (ꭓ2 (2) = 71,500; p < 0.001). The patients' mean follow-up period was 27.4 ± 21.7 months (3-84). Mortality due to tracheal surgery and major anastomotic complications were not observed. The minor anastomotic complication rate was 12.5%, the non-anastomotic complication rate was 17.5%. The effect of resection length and surgical experience were found to be statistically significant risk factors for anastomotic complications. CONCLUSIONS: Rigid dilatation does not provide significant palliation in complex stenosis. Bronchoscopic measurements give closer results than CT measurements in the preoperative estimation of resection length. The risk of anastomotic complications increases when the length of the resection increases and when the surgical experience is less.

ABSTRACT

The vaccines developed against severe acute respiratory syndrome coronavirus 2 are seen as the most crucial weapon in controlling the epidemic. It has been reported in early-stage vaccine studies that vaccines provide up to 95% protection against severe disease and mortality, even in the absence of symptomatic infection. Reports on vaccine breakthrough infections that developed after widespread vaccination are available in the literature. In addition to the general population, the course of vaccine breakthrough infections in immunocompromised patients is a matter of concern. This case report aimed to define severe coronavirus disease 2019 developing in a lung recipient who received 3 doses of inactivated virus vaccine.

ABSTRACT

BACKGROUND: Diffuse panbronchiolitis is a chronic airway disease characterized by diffuse inflammation of respiratory bronchioles and peribronchial tissue. We present a case of diffuse panbronchiolitis developed after lung transplantation, which to our knowledge has not been previously described in the literature. CASE REPORT: A 52-year-old white woman was admitted with reports of weakness, shortness of breath, and productive cough 6 months after bilateral sequential lung transplantation. Thorax computed tomography revealed the appearance of a budding branch pattern in the lower lobes of both lungs. Repeated transbronchial lung biopsies were not diagnostic. A lower lobe wedge biopsy with thoracotomy was performed in the patient, whose respiratory function gradually deteriorated. Dense lymphocyte infiltration in the respiratory bronchiole wall and foamy macrophage groups in the adjacent interstitial area were detected in the histopathologic sections. The dramatic response was achieved with pulse steroid therapy in a short time. Rapidly worsening clinical course and response to the pulse steroid therapy suggested acute cellular rejection. CONCLUSIONS: Acute cellular rejection is expected within the first year in lung transplant recipients. Diffuse panbronchiolitis may be a kind of clinical presentation in lung recipients and should be considered in patients who develop severe graft function loss in a short time.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a global health problem. However, the course of this disease in immunosuppressed patients remains unknown. This study aimed to describe the course of COVID-19 infection and its effects on lung transplant recipients. METHODS: This was a single-center, retrospective, observational study. The recipients with suspicious symptoms and/or a contact history with infected individuals were diagnosed with COVID-19 by performing a reverse transcription-polymerase chain reaction (RT-PCR) test using samples obtained from the nasopharynx swabs or bronchial lavage. We classified the patients into mild, moderate, and high severity groups according to their clinical conditions. In patients with positive RT-PCR results, cell cycle inhibitor drugs were withdrawn, while steroids were maintained at the same level as in patients without clinical deterioration. RESULTS: Of the seven recipients diagnosed with COVID-19 infection, one experienced a re-infection. Each recipient had at least one comorbidity. Smell disorder (12.5%), cough/dyspnea (37%), and fever/chills/shivering (37%) were the most frequent symptoms. The mean follow-up time after infection was 108 days. No deaths were recorded due to COVID-19; however, the pulmonary function test values of two recipients were decreased during subsequent follow-ups. CONCLUSION: In our small group of transplant recipients with COVID-19, there were two cases of pulmonary function deterioration and a case of re-infection, and no recipient died. It is suggested that steroid therapy should be initiated in the early period in patients with pulmonary opacities.

ABSTRACT

BACKGROUND/AIM: This retrospective study evaluated the clinical presentation, underlying lung disease, surgical indications, technique, treatment outcomes, and postoperative complications of pulmonary aspergilloma. MATERIALS AND METHODS: We evaluated 77 patients who underwent pulmonary resection of an aspergilloma at Atatürk Chest Diseases and Thoracic Surgery Research and Training Hospital between January 2000 and December 2013. The initial operations were 4 pneumonectomies, 24 lobectomies, 9 lobectomy plus myoplasties, 10 segmental resections, and 30 wedge resections. Six reoperations were carried out to deal with postoperative complications: 1 myoplasty, 2 completion lobectomies plus myoplasties, 2 myoplasties with rib resections, and 1 completion lobectomy. RESULTS: The subjects comprised 53 males (mean age: 44.26 (range: 10-73) years) and 24 females (mean age: 48.25 (range: 26-70) years). The most common indication for surgery was hemoptysis in 52 patients (67.53%). The most common underlying lung disease was tuberculosis in 37 patients (48.05%). Forty patients (51.94%) had a simple pulmonary aspergilloma and 37 (48.05%) had a complex pulmonary aspergilloma. Major complications occurred in 18 patients (23.37%). The postoperative mortality rate was 3.89%, with 3 patients dying. CONCLUSION: Surgical resection of pulmonary aspergilloma is the best way to prevent recurrent hemoptysis with low morbidity and mortality.
