To evaluate quantitative chest computed tomography (CT) methods for the detection of air trapping (AT) and to assess its diagnostic performance for the diagnosis of bronchiolitis obliterans syndrome (BOS) in single lung transplant (SLT) patients. Adult patients who had a SLT at a single transplant center and underwent CT scan after transplantation were retrospectively included. CT findings of air trapping were measured by three different methods: expiratory air-trapping index (ATIexp), mean lung density on expiratory acquisition (MLDexp) and expiratory to inspiratory ratio of mean lung density (E/I-ratio(MLD). Sensitivity, specificity and diagnostic accuracy of the three methods for the detection of BOS status evaluated by serial routine measures of pulmonary function tests (gold standard) were assessed. Forty-six SLT patients (52.2% females, mean age 58 ± 6 years) were included in the analysis, 12 (26%) patients with a diagnosis of BOS. Quantitative CT diagnosis of AT ranged from 26 to 35%. Sensitivity, specificity and accuracy of each method for the detection of BOS were 85.7%, 84.7% and 85.0% for ATIexp, 78.5%, 93.4% and 90.0% for MLD and 64.2%, 89.1% and 83.3% E/I-ratio(MLD), respectively. Quantitative measures of AT obtained from standard CT are feasible and show high specificity and accuracy for the detection of BOS in SLT patients.

Purpose Currently, pulmonary rehabilitation (PR) has a weak recommendation for idiopathic pulmonary fibrosis (IPF) and is often recommended for mild to moderate disease. We aimed to investigate the completion rate of PR in patients with advanced IPF, to analyze whether the severity of disease influences PR response and whether there is any difference between subjects who are able or not able to successfully complete the program. Methods Patients with IPF referred to lung transplantation (n = 48) were enrolled in an outpatient PR program including 3 times/wk supervised exercise training during 12 wk. A short-form 36-item health-related quality-of-life (HRQL) questionnaire and 6-min walk test distance (6MWD) were evaluated before and after PR. Results We found that 64.5% of patients successfully completed PR (31/48). Baseline forced vital capacity (FVC) and lung diffusion capacity for carbon monoxide (DLCO) were 49% ± 13% and 46% ± 17% of predicted, respectively. There was no difference comparing those who did and did not complete PR. In the former group, 6MWD (58 ± 63 m) and several domains of the HRQL questionnaire improved significantly. No significant association was found between markers of disease severity (FVC, DLCO, and dyspnea) and improvement in clinical outcomes. Conclusions Two-thirds of our sample with advanced IPF referred to lung transplant successfully attended PR and improved exercise capacity and HRQL, without association with markers of disease severity. No difference was found at baseline compared with subjects who were not able to complete the program.

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls). Survival after LTx was the main outcome; invasive mechanical ventilation (IMV), length of stay (LOS) in intensive care unit (ICU) and in hospital were secondary outcomes. Kaplan-Meier curves and Cox regression models were used in survival analyses. Cox regression models showed that the PRP group had a reduced 54.0% (hazard ratio = 0.464, 95% confidence interval 0.222–0.970, p = 0.041) risk of death. A lower number of patients in the PRP group required IMV for more than 24 hours after LTx (9.0% vs. 41.6% p = 0.001). This group also spent a mean of 5 days less in the ICU (p = 0.004) and 5 days less in hospital (p = 0.046). In conclusion, PRP PRP completion halved the risk of cumulative mortality in patients with IPF undergoing unilateral LTx

We report herein a case of thoracic infection due to Nocardia nova following lung re-transplantation performed for emphysema related to alpha-1-antitrypsin deficiency. The infection extended from the lung into the pleural space, thoracic wall, and mediastinum, presenting as pericarditis and empyema necessitatis. Nocardia nova was identified by 16S ribosomal deoxyribonucleic acid (rDNA) sequencing and phylogenetic analysis. According to a literature search of PubMed, LILACS and MEDLINE databases, we describe herein the first case of empyema necessitatis caused by N. nova species in a transplanted patient.

Background. Galactomannan (GM) detection in serum samples has been used to diagnose invasive aspergillosis (IA). Limited sensitivity has been observed in lung transplant recipients, for whom bronchoalveolar lavage (BAL) testing has been advocated. Because airway colonization with Aspergillus species occurs frequently in these patients, false-positive GM results have been reported if the cutoff validated for sera is used (i.e., 0.5). Methods. Herein, we prospectively studied BAL fluid samples from 60 lung transplant patients to determine the optimal cutoff for BAL GM testing. Only one sample per patient was studied. BAL samples were vortexed and processed according to the manufacturer's instructions for serum samples. Sensitivity, specificity, and likelihood ratios were calculated in reference to proven or probable IA cases using receiver operating characteristic analysis. Results. Eight patients had IA during the study (incidence 13.3%), including four patients with proven IA. Aspergillosis increased 5-fold the risk of death in lung transplant recipients. The positive predictive value of a positive BAL GM test at the 0.5 cutoff was low (24.2%). Raising the cutoff improved test specificity without compromising sensitivity. The best cutoff was defined at 1.5 (sensitivity 100% and specificity 90.4%). Conclusions. This study reinforces the importance of BAL GM testing in lung transplant recipients, particularly to exclude the diagnosis of IA. To minimize the frequency of false-positive results, a higher test cutoff should be applied to BAL samples, in comparison with serum samples.

A apresentação de lesão sincrônica pulmonar e hepática em um paciente com antecedente de carcinoma broncogênico operado gera a suspeita de recidiva tumoral e indica a necessidade de re-estadiamento. Apresentamos o caso de um paciente de 71 anos submetido à lobectomia pulmonar com ressecção de pericárdio e linfadenectomia mediastinal (T3N0M0). Cinco anos após a cirurgia, detectou-se a presença de uma nova lesão pulmonar. No re-estadiamento, foi diagnosticada uma lesão sincrônica no fígado. Apesar da forte suspeita de recidiva tumoral, prosseguiu-se a investigação e uma punção hepática revelou carcinoma hepatocelular. Para esclarecer a etiologia da lesão pulmonar (hipóteses de recidiva de carcinoma brônquico ou de metástase de carcinoma hepatocelular), foi realizada uma biópsia a céu aberto, compatível com reação inflamatória crônica com focos de antracose e de calcificação distrófica. O paciente foi então submetido à ressecção hepática não-regrada com intuito curativo. Teve boa evolução, com alta no 10º dia de pós-operatório. O presente relato destaca a importância do diagnóstico histopatológico em pacientes com antecedente de carcinoma broncogênico e suspeita de recidiva. Hipóteses diagnósticas e condutas terapêuticas são discutidas.The synchronous presentation of pulmonary and hepatic nodules in a patient with previously resected bronchogenic carcinoma raises suspicion of recurrence and mandates restaging. We present the case of a 71-year-old male with a history of lobectomy with pericardial resection and mediastinal lymphadenectomy (T3N0M0). At five years after the operation, he presented with a new pulmonary lesion. Restaging detected a synchronous nodule in the liver. Despite the strong suspicion of tumor recurrence, further investigation with a percutaneous liver biopsy revealed hepatocellular carcinoma. In order to investigate the etiology of the pulmonary lesion (hypotheses of recurrent bronchial cancer and of metastatic hepatocellular carcinoma), an open lung biopsy was performed, which revealed chronic inflammatory tissue with foci of anthracosis and dystrophic calcification. The patient was submitted to a non-anatomic resection of the liver lesion. The postoperative course was uneventful, and the patient was discharged on postoperative day 10. This report highlights the relevance of the histopathological diagnosis in patients with a history of bronchogenic carcinoma and suspicion of tumor recurrence. Differential diagnoses and the treatment administered are discussed.

Background: Many advances have substantially improved the clinical results of lung transplantation. However, the incidence of bronchial complications is still high, with significant impact on survival and limited interventional strategies for complex cases. Our aim is to evaluate the surgical management of bronchial complications following lung transplantation. Methods: From May 1989 to June 2007, 251 patients were submittedtolungtransplantationatourinstitution.Infivecases, thebronchialcomplicationsobservedweredealtwithopensurgicalprocedures. Results: Complications surgically dealt were one broncho-arterial fistula and four stenosis. One left upper sleeve lobectomy, one right upper sleeve lobectomy and three segmental bronchial resections with anastomosis were performed. In all five cases the surgical procedure was successful and optimal bronchial healing was observed. Three patients died due to causes unrelated to the bronchial anastomosis 5, 21 and 32 months after the bronchoplastic procedure. Two patients are still alive and functionally well at 52 and 70 months post-bronchoplasty. Conclusions: Surgical management of bronchial complications after lung transplantation may be the last resort in complex, recalcitrant cases, nevertheless it is a feasible procedure and can provide good results not only on short- but also long-term follow-up. # 2008 European Association for Cardio-Thoracic Surgery.

OBJETIVO: Avaliar as complicações pós-operatórias imediatas de doadores vivos de lobos pulmonares para transplante. MÉTODOS: Entre setembro de 1999 e maio de 2005 foram realizadas lobectomias em 32 doadores saudáveis para transplante pulmonar em 16 receptores. Os prontuários médicos destes doadores foram analisados retrospectivamente para verificar a incidência de complicações pós-operatórias e as alterações da função pulmonar após a lobectomia. RESULTADOS: Vinte e dois doadores (68,75%) não apresentaram complicações. Entre os 10 casos que apresentaram alguma complicação o derrame pleural foi a mais freqüente, ocorrendo em 5 deles (15,6% da amostra). Três doadores (9,3%) necessitaram de transfusão de hemácias e, em 2 casos, foi necessária nova intervenção cirúrgica devido a hemotórax. Um doador apresentou pneumotórax após a retirada do dreno de tórax e houve um caso de infecção respiratória. Ocorreram duas intercorrências intra-operatórias (6,25%): em um doador foi realizada broncoplastia do lobo médio; em outro, foi necessária a ressecção da língula. Não houve mortalidade cirúrgica nesta série. As provas de função pulmonar do pós-operatório demonstraram uma redução média de 20% no volume expiratório forçado no primeiro segundo (p < 000,1), em comparação com os valores verificados antes da cirurgia. CONCLUSÕES: A lobectomia em doadores pulmonares vivos para transplante apresenta elevado risco de complicações pós-operatórias e resulta em perda definitiva da função pulmonar Uma cuidadosa avaliação pré-operatória faz-se necessária para reduzir a incidência de complicações nos doadores vivos de lobos pulmonares para transplante.OBJECTIVE: To evaluate post-operative complications in living lobar lung transplant donors. METHODS: Between September of 1999 and May of 2005, lobectomies were performed in 32 healthy lung transplant donors for 16 recipients. The medical charts of these donors were retrospectively analyzed in order to determine the incidence of postoperative complications and alterations in pulmonary function after lobectomy. RESULTS: Twenty-two donors (68.75%) presented no complications. Among the 10 donors presenting complications, the most frequently observed complication was pleural effusion, which occurred in 5 donors (15.6% of the sample). Red blood cell transfusion was necessary in 3 donors (9.3%), and 2 donors underwent a second surgical procedure due to hemothorax. One donor presented pneumothorax after chest tube removal, and one developed respiratory infection. There were two intra-operative complications (6.25%): one donor required bronchoplasty of the middle lobe; and another required lingular resection. No intra-operative mortality was observed. Post-operative pulmonary function tests demonstrated an average reduction of 20% in forced expiratory volume in one second (p < 000.1) compared to pre-operative values. CONCLUSIONS: Lobectomy in living lung transplant donors presents high risk of post-operative complications and irreversible impairment of pulmonary function. Careful pre-operative evaluation is necessary in order to reduce the incidence of complications in living lobar lung transplant donors.

Objective: Determine cytomegalovirus infection incidence in lung transplantation under universal intravenous ganciclovir prophylaxis, and analyzing its effect on the lung transplant survival. Methods: 106 lung transplants performed between March/99 and Feb/04, 82 were studied, 24 were excluded due to death in the first month (n=24; 22.6%). Recipients received cyclosporine, azatioprine, and prednisone. Prophylactic ganciclovir was administered 10mg/kg/day for 3 weeks, followed by 5mg/kg/day, and 3x/week between 4th and 12th weeks. Whenever active infection was present, patients received ganciclovir 10mg/kg/day until attaining two negative antigenemia or after finishing the 21 days treatment. Peripheral blood pp65 cytomegalovirus antigenemia was used to identify active infection between weeks 3rd to 12th. It was monthly used from 4th to 12th month or whenever presenting clinical suspicion. Active infection was defined as any positive cell among 105 granulocytes. It was employed t Student, Ki-square and Fisher’s Exact tests, mean ± standard deviation, Kaplan Meier; it was considered significant p

In the present study, we aimed to determine the impact of lung transplantation (LTx) on pulmonary function tests (PFTs) and survival among patients with end-stage silicosis. We included patients with end-stange silicosis on the wait list for LTx, between January 1989 and July 2015 (N=26). Sixteen of these patients received LTx; 10 were eligible, but did not undergo LTx (non-LTx) during the study period. Retrospective information on PFTs (spirometry [volumes and flows], 6-minute walking test [6MWT], and DLCO) was retrieved from patients’ medical charts, including baseline information for all patients, and follow-up information for the LTx. At baseline, most patients presented with spirometric and 6MWT values that were suggestive of severe disease (FEV1/FVC 76.5±29.7; 6MWT 267.4±104.5m). Significant increases in these values were observed at follow-up in the LTx (p=0.036 and 0.151, respectively). The overall median survival of patients in the LTx and non-LTx was 3.35 years (95% CI: 0.16–14.38) and 0.78 years (95% confidence interval [CI]: 0.12–3.65) (p=0.002), respectively. For patients with end-stage silicosis, LTx offers significant benefits regarding pulmonary function and survival when compared to non-LTx, and is a reliable tool to help this critical population of patients, whose only treatment option is LTx.

Background Advanced age has been a relative contraindication to lung transplantation. However, the exact age limit for this procedure has not yet been established. The aim of this work is to present our experience with this particular group. Methods This retrospective review included medical charts of patients who underwent lung transplantation at our institution from January 2004 to February 2009: namely, 112 cadaveric lung transplants with 12 patients (10.7%) >65 years old. Results There were 9 male patients and the overall mean age was 68 years (range 66–72). The indications were pulmonary fibrosis in 8 and emphysema in 4 cases. Four patients had mild coronary artery disease and 4 systemic hypertension. All of the procedures were unilateral and only 2 required extracorporeal circulation. Only 5 patients received blood product transfusions intraoperatively; the mean ischemic time was 222 minutes. Four patients developed primary graft dysfunction, the mean requirement for mechanical ventilation was 30 hours, and the mean intensive care unit stay, 11 days. Postoperative complications were respiratory infections (n = 8), catheter-related infection (n = 1), atrial fibrillation (n = 2). The mean hospital stay was 28 days and the 1-year survival was 75%. Conclusion Lung transplantation is a feasible option for well-selected patients with end-stage pulmonary disease who are >65 years old. Our study reinforces the modern trend for unilateral procedures in this situation.

Background Lymphangioleiomyomatosis (LAM), a rare cystic disease characterized by proliferation of smooth muscle cells in the lung interstitium, almost exclusively affects females in their reproductive years. Lung transplantation has been extablished as effective therapy for end-stage pulmonary LAM. Methods This retrospective study includes lung transplantation patients with LAM at a single institution between 1989 and 2009. Results During the study period we performed 300 lung transplantations, and in 10 cases the recipients had LAM. All patients were females with a mean age of 43.8 years. The mean time from the diagnosis to lung transplantation was 5 years. Seven patients had experienced previous pneumothoraces, five of whom were treated with pleurodesis. In all patients we performed a single-lung transplantation (left-sided = 9 and right-sided = 1). In three cases, the pleurodesis was on the same side as the transplantation, with great intraoperative bleeding in one subject (left pleurectomy). There was one early death due to infective endocarditis at posttransplant day 19. The median length of mechanical ventilation was 13 hours, while the mean hospital stay was 16.75 days. There was no case of chylothorax. Late complications included one case of native lung pneumothorax, one diaphragmatic hernia, one posttransplant lymphoproliferative disease, one respiratory sepsis, and one mycobacterial infection. The 1- and 3-year survival rates were 90% and 80%, respectively. Conclusion Lung transplantation is a feasible therapeutic option for patients with LAM, despite previous ipsilateral pleurodesis. The left-sided predilection for our procedures may have been responsible for the absence of chylothorax in this series.

Peripheral bronchial carcinoids are uncommon. Their presentation as synchronous tumors is rare and limited to anecdotal cases.We report the case of a 62-year-old female with the radiological finding of multiple bilateral nodular lesions. Bilateral sequential thoracotomies were performed and all three nodules were treated by sublobar resections. Pathological examination revealed all specimens to be carcinoid tumors and subsequent investigation confirmed the lung as the primary site. A review of previous cases of multiple carcinoids is presented and the particularities of their management are discussed.

The best strategy for control of cytomegalovirus (CMV) infection in lung transplant patients is still not determined. The aim of this study was to document the incidence of CMV infection in a cohort of lung transplant recipients under universal prophylaxis with intravenous ganciclovir. All patients received immunosuppressive regimens consisting of cyclosporine, azathioprine, and prednisone. Regardless of CMV serostatus, intravenous ganciclovir was prescribed for every patient in the first 3 months post-transplantation. CMV infection was defined as the detection of CMV pp65 in leukocytes. Eighty-two lung transplant patients were included over a 5-year period. The incidence of CMV infection in the first year post-transplantation was 68.3%, occurring after a median length of 114 days (range, 26-343 days). This study revealed a high incidence of CMV infection in the first year following lung transplantation despite prolonged universal ganciclovir prophylaxis.

Objective The aim of this study was to assess high-resolution computed tomographic (HRCT) findings at presentation in lung transplant patients diagnosed with pulmonary Aspergillus infection. Materials and methods We retrospectively reviewed HRCT findings from 23 patients diagnosed with pulmonary aspergillosis. Imaging studies were performed 2–5 days after the onset of symptoms. The patient sample comprised 12 men and 11 women aged 22–59 years (mean age, 43.6 years). All patients had dyspnea, tachypnea, and cough. Diagnoses were established with Platelia Aspergillus enzyme immunoassays for galactomannan antigen detection in bronchoalveolar lavage and recovery of symptoms, and HRCT findings after voriconazole treatment. The HRCT scans were reviewed independently by two observers who reached a consensus decision. Results The main HRCT pattern, found in 65% ( n = 15) of patients, was centrilobular tree-in-bud nodules associated with bronchial thickening. This pattern was described in association with areas of consolidation and ground-glass opacities in 13% ( n = 3) of patients. Consolidation and ground-glass opacities were the main pattern in 22% ( n = 5) of patients. The pattern of large nodules with and without the halo sign was observed in 13% ( n = 3) of patients, and were associated with consolidation and ground-glass opacities in one case. Conclusion The predominant HRCT findings in lung transplant patients with pulmonary aspergillosis were bilateral bronchial wall thickening and centrilobular opacities with the tree-in-bud pattern. Ground-glass opacities and/or bilateral areas of consolidation were also common findings. Pulmonary nodules with the halo sign were found in only 13% of patients.

Cryptococcus gattii are closely related species of encapsulated yeast-like fungi involved in the etiology of cryptococcosis, especially in immunocompetent individuals. Dissemination with involvement of many organ systems is common. On the other hand, cellulitis in an immunossupressed patient caused by C. gattii is rare. We present a case of disseminated disease caused by Cryptococcus gattii in a lung transplant recipient who manifested cellulitis. The disease was also complicated by a lung carcinoma. We emphasize that cryptococcal cellulitis related to C. gattii in solid organ transplant (SOT) recipients should be considered in the differential diagnosis of acute bacterial skin infections.

A discinesia ciliar primaria e uma condicao rara que evolui com a formacao de bronquiectasias, e invariavelmente o tratamento cirurgico esta indicado; alguns desses pacientes evoluem para doenca pulmonar avancada, refrataria ao tratamento clinico e as resseccoes cirurgicas, tornando-se, portanto, candidatos ao transplante pulmonar. Quando associada a dextrocardia, bronquiectasias e sinusopatia cronica, a discinesia ciliar primaria e chamada de sindrome de Kartagener e e considerada como uma contraindicacao de transplante pulmonar por muitos centros.

OBJETIVO: Apresentar o acompanhamento a longo prazo do primeiro caso de transplante pulmonar intervivos realizado na America Latina. DESCRICAO: Paciente do sexo masculino, com 12 anos de idade, portador de bronquiolite obliterante com doenca pulmonar avancada. Fazia uso de oxigenio domiciliar continuo, com dispneia aos minimos esforcos. Foi submetido a transplante pulmonar bilateral com doadores vivos. A cirurgia foi realizada utilizando os lobos inferiores esquerdo e direito de dois doadores diferentes e com grau de parentesco com o receptor. No segundo lado (direito), foi necessario emprego de circulacao extracorporea. O transplante nao teve intercorrencias, e o paciente foi extubado com 14 horas de pos-operatorio; com 44 dias, recebeu alta hospitalar, apos a resolucao de complicacoes infecciosas, imunologicas e medicamentosas. Apos 12 anos de seguimento, encontra-se com funcao pulmonar preservada e desempenha normalmente suas atividades. COMENTARIOS: O transplante pulmonar intervivos e um procedimento de alta complexidade que pode contribuir para o tratamento de algumas pneumopatias na infância. Essa populacao se beneficia dessa abordagem, uma vez que a disponibilidade de doadores pediatricos e muito rara, e as pneumopatias pediatricas tendem a seguir um curso imprevisivel.

Background. Lung transplantation (LT) has been established as a current therapy for selected patients with end-stage lung disease. Different prognostic factors have been reported by transplant centers. The objective of this study is to report our recent results with LT and to search for prognostic factors. Methods. We performed a retrospective analysis of 130 patients who underwent LT at our institution from January 2004 to July 2009. Donor, recipient, intraoperative, and postoperative variables were collected. Results. The mean age was 53.14 years (ranging from 8 to 72 years) and 80 (61.5%) were male. The main causes of end-stage respiratory disease were pulmonary fibrosis 53 (40.7%) and chronic obstructive pulmonary disease 52 (40%). The actuarial 1-year survival was 67.7%. Variables correlated with survival were age (P=0.004), distance in the 6-min walk test (P=0.007), coronary heart disease (P=0.001),cardiopulmonary bypass (P=0.02), intraoperative transfusion of red blood cells (P=0.016), increasing central venous pressure at 24th postoperative hour (P=0.001), increasing pulmonary capillary wedge pressure at 24th postoperative hour (P=0.01); length of intubation (P

The synchronous presentation of pulmonary and hepatic nodules in a patient with previously resected bronchogenic carcinoma raises suspicion of recurrence and mandates restaging. We present the case of a 71-year-old male with a history of lobectomy with pericardial resection and mediastinal lymphadenectomy (T3N0M0). At five years after the operation, he presented with a new pulmonary lesion. Restaging detected a synchronous nodule in the liver. Despite the strong suspicion of tumor recurrence, further investigation with a percutaneous liver biopsy revealed hepatocellular carcinoma. In order to investigate the etiology of the pulmonary lesion (hypotheses of recurrent bronchial cancer and of metastatic hepatocellular carcinoma), an open lung biopsy was performed, which revealed chronic inflammatory tissue with foci of anthracosis and dystrophic calcification. The patient was submitted to a non-anatomic resection of the liver lesion. The postoperative course was uneventful, and the patient was discharged on postoperative day 10. This report highlights the relevance of the histopathological diagnosis in patients with a history of bronchogenic carcinoma and suspicion of tumor recurrence. Differential diagnoses and the treatment administered are discussed.

After James Hardy's pioneer initiative (1963) and the advance of lung preservation techniques, the progress of immuno-suppressive treatment with the discovery of cyclosporine and the implementation of international guidelines for the selection of lung transplantation donors and candidates [1-3], lung transplantation became the treatment of choice for many lung diseases in the terminal state. However, lung transplantation morbidity and mortality rates remain elevated, and early postoperative state care is indispensable for a positive outcome. The aim of the present study is to examine the experience in the intensive management of early postoperative lung transplantation patients of the Complexo Hospitalar Santa Casa Group of Porto Alegre, Brazil.
