    Single-lung transplantation, long successful in resolving interstitial lung disease, can now be used in COPD patients and shows promise in managing pulmonary hypertension. The bilateral procedure, which often avoids cardiopulmonary bypass, is preferred when chronic airway infection is present. Heart-lung transplants, now rare, are used when pulmonary hypertension is complicated by congestive cardiomyopathy or irreparable cardiac defects. Mechanical ventilation, prior cardiothoracic surgery, and corticosteroid use no longer constitute absolute contraindications to lung transplantation. The growing scarcity of donor organs is increasing waiting times; thus, earlier recognition of potential recipients is necessary.

    Hereditary pulmonary alveolar proteinosis (PAP) caused by mutations in CSF2RA or CSF2RB, which encode GM-CSF receptor α and β respectively, is a rare disease. Although some experimental therapeutic strategies have been proposed, no clinical evidence has yet been reported. We herein describe the clinical course and recurrence of hereditary PAP after lung transplantation. A 36-year-old woman developed PAP of unknown etiology. She underwent bilateral lung transplantation from living donors at the age of 42 years because of severe respiratory failure complicated by pulmonary fibrosis. However, PAP recurred after 9 months, and we found that donor-origin alveolar macrophages had been almost completely replaced with recipient-origin macrophages. We performed a genetic analysis and identified a point deletion in the CSF2RB gene that caused a GM-CSF receptor-mediated signaling defect. PAP progressed with fibrosis in both transplanted lungs, and the patient died of respiratory failure 5 years after the lung transplantation. Distinct from recent reports on pulmonary macrophage transplantation in mice, this case suggests that human alveolar macrophages might not maintain their population only by self-renewal but may depend on a supply of precursor cells from the circulation. Bone marrow transplantation should be considered for treatment of severe PAP with GM-CSF receptor gene deficiency. PMID:27595063

    ABSTRACT Lung transplantation is a globally accepted treatment for some advanced lung diseases, giving the recipients longer survival and better quality of life. Since the first transplant successfully performed in 1983, more than 40 thousand transplants have been performed worldwide. Of these, about seven hundred were in Brazil. However, survival of the transplant is less than desired, with a high mortality rate related to primary graft dysfunction, infection, and chronic graft dysfunction, particularly in the form of bronchiolitis obliterans syndrome. New technologies have been developed to improve the various stages of lung transplant. To increase the supply of lungs, ex vivo lung reconditioning has been used in some countries, including Brazil. For advanced life support in the perioperative period, extracorporeal membrane oxygenation and hemodynamic support equipment have been used as a bridge to transplant in critically ill patients on the waiting list, and to keep patients alive until resolution of the primary dysfunction after graft transplant. There are patients requiring lung transplant in Brazil who do not even come to the point of being referred to a transplant center because there are only seven such centers active in the country. It is urgent to create new centers capable of performing lung transplantation to provide patients with some advanced forms of lung disease a chance to live longer and with better quality of life.

    Temporary graft dysfunction with gas exchange abnormalities is a common finding during the postoperative course of a lung transplant and is often determined by the post-reimplantation syndrome. Supportive measures including oxygen by mask, inotropes, diuretics, and pulmonary vasodilators are usually effective in non-severe post-reimplantation syndromes. However, in less-responsive clinical pictures, tracheal intubation with positive pressure ventilation, or non-invasive positive pressure ventilation (NIV), is necessary. We report on the clinical course of two patients suffering from refractory hypoxemia due to post-reimplantation syndrome treated with NIV in the prone and Trendelenburg positions. NIV was well tolerated and led to resolution of atelectactic areas and dishomogeneous lung infiltrates. Repeated turning from supine to prone under non invasive ventilation determined a stable improvement of gas exchange and prevented a more invasive approach. Even though NIV in the prone position has not yet entered into clinical practice, it could be an interesting option to achieve a better match between ventilation and perfusion. This technique, which we successfully applied in lung transplantation, can be easily extended to other lung diseases with non-recruitable dorso-basal areas.

    Humoral immune deficiencies have been associated with noninfectious disease complications including autoimmune cytopenias and pulmonary disease. Herein we present a patient who underwent splenectomy for autoimmune cytopenias and subsequently was diagnosed with humoral immune deficiency in the context of recurrent infections. Immunoglobulin analysis prior to initiation of intravenous immunoglobulin (IVIG) therapy was notable for low age-matched serum levels of IgA (11 mg/dL), IgG2 (14 mg/L), and IgG4 (5 mg/L) with a preserved total level of IgG. Flow cytometry was remarkable for B cell maturation arrest at the IgM+/IgD+ stage. Selective screening for known primary immune deficiency-causing genetic defects was negative. The disease course was uniquely complicated by the development of pulmonary arteriovenous malformations (AVMs), ultimately requiring bilateral lung transplantation in 2012. This is a patient with humoral immune deficiency that became apparent only after splenectomy, which argues for routine immunologic evaluation prior to vaccination and splenectomy. Lung transplantation is a rare therapeutic endpoint and to our knowledge has never before been described in a patient with humoral immune deficiency for the indication of pulmonary AVMs. PMID:25379312

    Lung transplantation represents the gold-standard therapy for patients with end-stage lung disease. Utilization of this therapy continues to rise. The Lung Transplant Program at Duke University Medical Center was established in 1992, and since that time has grown to one of the highest volume centers in the world. The program to date has performed over 1,600 lung transplants. This report represents an up-to-date review of the practice and management strategies employed for safe and effective lung transplantation at our center. Specific attention is paid to the evaluation of candidacy for lung transplantation, donor selection, surgical approach, and postoperative management. These evidence-based strategies form the foundation of the clinical transplantation program at Duke. PMID:27076968

    In this manuscript, we present the first experience of evaluating donation after circulatory death (DCD) lungs, using the normothermic preservation Organ Care System (OCS) and subsequent successful transplantation. The OCS could be a useful tool for the evaluation of marginal lungs from DCD donors as it allows a proper recruitment and bronchoscopy in such donations in addition to continuous ex-vivo perfusion and assessment and treatment during transport. The OCS could potentially be a standard of care in the evaluation of marginal lungs from DCD.

    Summary Study of lung xenografts has proven useful to understand the remaining barriers to successful transplantation of other organ xenografts. In this chapter, the history and current status of lung xenotransplantation will be briefly reviewed and two different experimental models, the ex vivo porcine-to-human lung perfusion and the in vivo xenogeneic lung transplantation, will be presented. We will focus on the technical details of these lung xenograft models in sufficient detail, list the needed materials and mention analysis techniques to allow others to adopt them with minimal learning curve.

    Since the first successful lung transplant 30 years ago, lung transplantation has rapidly become an established standard of care to treat end-stage lung disease in selected patients. Advances in lung preservation, surgical technique, and immunosuppression regimens have resulted in the routine performance of lung transplantation around the world for an increasing number of patients, with wider indications. Despite this, donor shortages and chronic lung allograft dysfunction continue to prevent lung transplantation from reaching its full potential. With research into the underlying mechanisms of acute and chronic lung graft dysfunction and advances in personalized diagnostic and therapeutic approaches to both the donor lung and the lung transplant recipient, there is increasing confidence that we will improve short- and long-term outcomes in the near future.

    Lung transplantation is a complex, high-risk, potentially life-saving therapy for the end-stage lung disease of cystic fibrosis (CF). The decision to pursue transplantation involves comparing the likelihood of survival with and without transplantation as well as assessing the effect of wait-listing and transplantation on the patient's quality of life. Although recent population-based analyses of the US lung allocation system for the CF population have raised controversies about the survival benefits of transplantation, studies from the United Kingdom and Canada have suggested a definite survival advantage for those receiving transplants. In response to these and other controversies, leaders in transplantation and CF met together in Lansdowne, Virginia, to consider the state of the art in lung transplantation for CF in an international context, focusing on advances in surgical technique, measurement of outcomes, use of prognostic criteria, variations in local control over listing, and prioritization among the United States, Canada, the United Kingdom, and The Netherlands, patient adherence before and after transplantation and other issues in the broader context of lung transplantation. Finally, the conference members carefully considered how efforts to improve outcomes for lung transplantation for CF lung disease might best be studied. This Roundtable seeks to communicate the substance of our discussions. PMID:20008865

    Lung transplantation survival remains significantly impacted by infections and the development of chronic rejection manifesting as bronchiolitis obliterans syndrome (BOS). Traditional microbiologic data has provided insight into the role of infections in BOS. Now, new non-culture-based techniques have been developed to characterize the entire population of microbes resident on the surfaces of the body, also known as the human microbiome. Early studies have identified that lung transplant patients have a different lung microbiome and have demonstrated the important finding that the transplant lung microbiome changes over time. Furthermore, both unique bacterial populations and longitudinal changes in the lung microbiome have now been suggested to play a role in the development of BOS. In the future, this technology will need to be combined with functional assays and assessment of the immune responses in the lung to help further explain the microbiome's role in the failing lung allograft.

    The indication for nephrectomy prior to kidney transplantation has changed. Contrary to the formerly in nearly all transplantation centres practiced one-time two-sided nephrectomy, at present the removal of the patient's own kidneys prior to transplantation is done only if strictly indicated. In contrast to other transplantation centres which, if indicated, still today carry out bilateral nephrectomy prior to transplantation is done only if strictly indicated. In contrast to other transplantation centres which, if indicated, still today carry out bilateral nephrectomy prior to transplantation, since 1977 the transplantation centre of Munich prefers the two-time bilateral nephrectomy. Technique, surgical approach, indication and results of our method are presented. In the course of the discussion the disadvantages of the one-time bilateral nephrectomy are opposed to the advantages of the two-time method.

    BACKGROUND: Hypersensitivity pneumonitis (HP) is an inhaled antigen-mediated interstitial lung disease (ILD). Advanced disease may necessitate the need for lung transplantation. There are no published studies addressing lung transplant outcomes in HP. We characterized HP outcomes compared with referents undergoing lung transplantation for idiopathic pulmonary fibrosis (IPF). METHODS: To identify HP cases, we reviewed records for all ILD lung transplantation cases at our institution from 2000 to 2013. We compared clinical characteristics, survival, and acute and chronic rejection for lung transplant recipients with HP to referents with IPF. We also reviewed diagnoses of HP discovered only by explant pathology and looked for evidence of recurrent HP after transplant. Survival was compared using Kaplan-Meier methods and Cox proportional hazard modeling. RESULTS: We analyzed 31 subjects with HP and 91 with IPF among 183 cases undergoing lung transplantation for ILD. Survival at 1, 3, and 5 years after lung transplant in HP compared with IPF was 96%, 89%, and 89% vs 86%, 67%, and 49%, respectively. Subjects with HP manifested a reduced adjusted risk for death compared with subjects with IPF (hazard ratio, 0.25; 95% CI, 0.08-0.74; P = .013). Of the 31 cases, the diagnosis of HP was unexpectedly made at explant in five (16%). Two subjects developed recurrent HP in their allografts. CONCLUSIONS: Overall, subjects with HP have excellent medium-term survival after lung transplantation and, relative to IPF, a reduced risk for death. HP may be initially discovered only by review of the explant pathology. Notably, HP may recur in the allograft. PMID:25412059

    Lung transplantation has been a widely accepted treatment modality for patients with end-stage chronic obstructive lung disease (COPD). COPD is the most frequent indication for lung transplantation according to the report from International Society for Lung and Heart Transplantation. However, it is a minor population in Japan. A total of 204 lung transplants have been performed in Japan to date. Among them, 10 patients were suffering from severe COPD. Nine of them received cadaveric lung transplantation and one received living-donor lobar lung transplantation. All are currently alive during follow-up period of 3-87 months.

    This case study describes a patient who developed peanut allergy following lung transplantation. A 54-year-old woman underwent bilateral lung transplantation on June 2009 owing to severe chronic obstructive pulmonary disease. She had no history of food allergy before transplantation. The donor, however, was a 20-year-old man who was fatally injured during an automobile accident; he was allergic to peanuts. At 3 months after transplantation, the lung recipient presented with acute dyspnea and urticaria 15 minutes after consuming food containing peanut derivatives. Pre- and posttransplantation recipient blood samples analyzed for the presence of IgE antibodies specific for peanut allergens confirmed that the allergy had been passively transfered as a consequence of transplantation. Food allergy following solid organ transplantation is thought to be rare, mostly occurring in children. Two mechanisms may explain the observations described for the patient reported in this study: de novo development of peanut allergies after transplantation, or passive transfer of peanut allergies from a peanut-sensitized organ donor. This case report documenting pre- and posttransplantation IgE status in a lung transplantation case suggested that the allergic status of organ donors should be thoroughly assessed before transplantation, and potential allergy transfer risks must be discussed with the transplant team and the patient.

    Lung transplantation offers the hope of prolonged survival and significant improvement in quality of life to patients that have advanced lung diseases. However, the medical literature lacks strong positive evidence and shows conflicting information regarding survival and quality of life outcomes related to lung transplantation. Decisions about the use of lung transplantation require an assessment of trade-offs: do the potential health and quality of life benefits outweigh the potential risks and harms? No amount of theoretical reasoning can resolve this question; empiric data are needed. Rational analyses of these trade-offs require valid measurements of the benefits and harms to the patients in all relevant domains that affect survival and quality of life. Lung transplant systems and registries mainly focus outcomes assessment on patient survival on the waiting list and after transplantation. Improved analytic approaches allow comparisons of the survival effects of lung transplantation versus continued waiting. Lung transplant entities do not routinely collect quality of life data. However, the medical community and the public want to know how lung transplantation affects quality of life. Given the huge stakes for the patients, the providers, and the healthcare systems, key stakeholders need to further support quality of life assessment in patients with advanced lung disease that enter into the lung transplant systems. Studies of lung transplantation and its related technologies should assess patients with tools that integrate both survival and quality of life information. Higher quality information obtained will lead to improved knowledge and more informed decision making. PMID:19131538

    Lung transplantation has become in recent years a therapeutic option for infantswith terminal lung disease with similar results to transplantation in adults.In Spain, since 1996 114 children lung transplants have been performed; this corresponds to3.9% of the total transplant number.The most common indication in children is cystic fibrosis, which represents between 70-80% of the transplants performed in adolescents. In infants common indications areinterstitial lung disease and pulmonary hypertension.In most children a sequential double lung transplant is performed, generally with the help ofextracorporeal circulation. Lung transplantation in children presents special challenges in monitoring and follow-up, especially in infants, given the difficulty in assessing lung function and performing transbronchial biopsies.There are some more specific complications in children like postransplant lymphoproliferative syndrome or a greater severity of respiratory virus infections .After lung transplantation children usually experiment a very important improvement in their quality of life. Eighty eight per cent of children have no limitations in their activity after 3 years of transplantation.According to the registry of the International Society for Heart & Lung Transplantation (ISHLT) survival at 5 years of transplantation is 54% and at 10 years is around 35%.

    A recent clinical trial provided evidence that ex vivo lung perfusion (EVLP) results in optimized human donor lungs for transplantation. Excellent recipient outcomes were documented after 4 h of normothermic perfusion. We report a clinical case utilizing remote EVLP to assess and improve function of initially otherwise unacceptable injured donor lungs followed by transportation and subsequent bilateral lung transplantation in a patient with virally induced refractory respiratory failure supported with extracorporeal membrane oxygenation. This is the first lung transplantation with the application of remote EVLP, wherein the donor lungs were transported from the donor hospital to a center for EVLP and then transported to another hospital for transplantation. It is also the first case of lung transplantation in the United States utilizing EVLP for functional optimization leading to successful transplantation. Organ procurement data, EVLP assessment, and the pre- and postoperative course of the recipient are presented. The available evidence supporting EVLP, the humanitarian and cooperative utilization of lungs otherwise discarded, are discussed. PMID:23009140

    BACKGROUND Lung transplantation remains the gold standard treatment for patients with end-stage lung disease. Lobar lung transplantation allows for transplantation of size-mismatch donor lungs in small recipients; however, donor lung volume reduction represents a challenging surgical technique. In this paper we present our initial experience with bilateral lobectomy in donor lungs before lobar lung transplantation using normothermic perfusion on the Organ Care System (OCS) Lung. MATERIAL AND METHODS Specifics of the surgical technique for donor lung instrumentation on the OCS, lobar dissection on the OCS, and right and left donor lobectomies are presented in detail. RESULTS Potential advantages of the use of the OCS for lobectomy for lobar lung transplantation are described in this section. Donor lung volume reduction utilizing OCS appeared to be easier and safer compared to the conventional cold storage technique, due to continuous perfusion of the lungs with blood and well-distended vessels that offer the feel of live lobectomy. Moreover, the OCS represents a platform for donor organ assessment and optimization of its function before transplantation. CONCLUSIONS Donor lung volume reduction was safe and feasible utilizing the OCS, which could be a useful tool for volume reduction in cases of size mismatch. Further research is needed to evaluate early and long-term results after lobar lung transplantation using the OCS in clinical studies. PMID:27425199

    BACKGROUND--To date there are no data on the effects of lung transplantation on diaphragmatic function in patients with end stage chronic obstructive pulmonary disease (COPD). It is not known whether the relation between the transdiaphragmatic pressure (PDI) and lung volume is altered in recipients after transplantation as a result of changes in diaphragmatic structure caused by chronic hyperinflation. The effect of lung transplantation on diaphragmatic strength was determined in patients with COPD and the relation between postoperative PDI and lung volume analysed. METHODS--Diaphragmatic strength was assessed in eight double lung transplant recipients, six single lung transplant recipients, and in 14 patients with COPD whose lung function was similar to those of the transplant recipients preoperatively. PDI obtained during unilateral and bilateral phrenic nerve stimulation at 1 Hz (twitch PDI) at functional residual capacity (FRC) and during maximal sniff manoeuvres (sniff PDI) at various levels of inspiratory vital capacity (VCin) served as parameters for diaphragmatic strength. Sniff PDI assessed at the various VCin levels were used to analyse the PDI/lung volume relation. RESULTS--Lung transplantation caused a reduction in lung volume, especially in the double lung transplant recipients. As a consequence sniff PDI was higher in the double lung transplant recipients than in the patients with COPD at all levels of VCin analysed. However, sniff PDI values analysed at comparable intrathoracic gas volumes were not reduced in the patients with COPD when compared with those who underwent lung transplantation. Bilateral twitch PDI values were similar in the patients with COPD and in the lung transplant recipients. In the single lung transplant recipients unilateral twitch PDI values were similar on the transplanted and the non-transplanted side. The relation between PDI and lung volume was similar in the patients with COPD and in the lung transplant recipients

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

    When conservative treatment fails, lung transplantation often remains the only therapeutic option for patients with end stage parenchymal or vascular lung diseases. According to the statistics of the International Society for Heart and Lung Transplantation, in 2010 more than 3500 lung transplantations have been performed worldwide. The Department of Thoracic Surgery at the University of Vienna is considered to be one of the world's leading lung transplantation centres; in the last year 115, since 1989 more than 1500 lung transplantation procedures under the supervision of Prof. Dr. Walter Klepetko. Similar to other Central-European countries, lung transplantation procedures of Hungarian patients have also been performed in Vienna whithin the framework of a twinning aggreement. However, many crucial tasks in the process, such indication and patient selection preoperative rehabilitation organ procurement and long term follow-up care have been stepwise taken over by the Hungarian team. Although the surgery itself is still preformed in Vienna, professional experience is already available in Hungary, since the majority of Hungarian recipients have been transplanted by hungarian surgeons who are authors of this article the professional and personal requirements of performing lung transplantations are already available in Hungary. The demand of performing lung transplantation in Hungary has been raising since 1999 and it soon reaches the extent which justifies launching of an individual national program. Providing the technical requirements is a financial an organisational issue. In order to proceed, a health policy decision has to be made.

    Despite preventive measures, lung hyperinflation is a relatively common complication following single lung transplantation to treat pulmonary emphysema. The progressive compression of the graft can cause mediastinal shift and respiratory failure. In addition to therapeutic strategies such as independent ventilation, the treatment consists of the reduction of native lung volume by means of lobectomy or lung volume reduction surgery. We report two cases of native lung hyperinflation after single lung transplantation. Both cases were treated by means of lobectomy or lung volume reduction surgery.

    OR nurses play an important role in organ procurement. They are responsible for gathering the necessary equipment, which includes cardioplegia supplies, normal saline, a sterile container for transplantation of the heart, a sterile retractor, vascular clamps, and dissection instruments. Orthotopic heart transplantation involves excision of the recipient heart with placement of the donor heart in a normal anatomic position. Heterotopic transplant, which consists of placing the donor heart in the right side of the chest parallel to the native heart, is rarely used. In heart-lung transplantation procedures, attention is given to the removal of the heart and each lung separately to prevent injury to the vagus, phrenic, and laryngeal nerves.

    There are no European recommendations on issues specifically related to lung transplantation (LTX) in cystic fibrosis (CF). The main goal of this paper is to provide CF care team members with clinically relevant CF-specific information on all aspects of LTX, highlighting areas of consensus and controversy throughout Europe. Bilateral lung transplantation has been shown to be an important therapeutic option for end-stage CF pulmonary disease. Transplant function and patient survival after transplantation are better than in most other indications for this procedure. Attention though has to be paid to pretransplant morbidity, time for referral, evaluation, indication, and contraindication in children and in adults. This review makes extensive use of specific evidence in the field of lung transplantation in CF patients and addresses all issues of practical importance. The requirements of pre-, peri-, and postoperative management are discussed in detail including bridging to transplant and postoperative complications, immune suppression, chronic allograft dysfunction, infection, and malignancies being the most important. Among the contributors to this guiding information are 19 members of the ECORN-CF project and other experts.

    Although lung transplantation has become a life-saving option for patients with end-stage lung disease, this intervention is hampered by a shortage of lungs in view of the growing number of people on the waiting list. Lungs are retrieved from only a small percentage of multiorgan donors, and the transplantation and intensive-care communities have recognised the need to develop innovative methods to expand the donor pool. Advancements in lung-preservation techniques in the preretrieval and postretrieval periods have increased the pool of available donors, and novel research and discoveries in this area have steadily improved post-transplantation adverse events. This Review summarises current best practice and the latest research on intensive-care management of a potential lung donor. We also discuss lung-preservation techniques, including advancements in normothermic ex-vivo lung perfusion, and the potential for a personalised medicine approach to the organ. PMID:24429157

    Twelve single lung and nine double lung transplant recipients were studied before transplantation and at 3 months and 1 year after transplantation with serial right and left ventricular radionuclide angiograms. The resting right ventricular ejection fraction increased in the double lung recipients from 31% +/- 5% before transplantation to 43% +/- 11% at 3 months after transplantation (p less than 0.05) and then remained stable to 1 year. The single lung recipients also demonstrated a significant rise in ejection fraction from 25% +/- 11% before transplantation to 36% +/- 12% at 3 months after transplantation. Again, this remained stable to 1 year. The exercise right ventricular ejection fraction also showed a significant posttransplantation rise in the double lung recipients (p less than 0.005) that remained stable to 1 year. In the single lung recipients a trend was seen for a rise in the exercise right ventricular ejection fraction that did not reach statistical significance by 1 year after transplantation. Neither group had a significant change in rest or exercise left ventricular ejection fraction. The systemic blood pressure increased significantly by 1 year after transplantation in both groups. The heart rate increase with exercise at 3 months after transplantation was significantly greater in the single lung group (42 +/- 13 beats/min) than in the double lung group (14 +/- 13 beats/min) (p less than 0.005). These data indicate that a significant improvement in right ventricular function occurs after single and double lung transplantation.

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    Before 2005, time accrued on the lung transplant waiting list counted towards who was next in line for a donor lung. Then in 2005 the lung allocation scoring system was implemented, which meant the higher the illness severity scores, the higher the priority on the transplant list. Little is known of the lung transplant candidates who were listed before 2005 and were caught in the transition when the lung allocation scoring system was implemented. A narrative analysis was conducted to explore the illness narratives of seven lung transplant candidates between 2006 and 2007. Arthur Kleinman's concept of illness narratives was used as a conceptual framework for this study to give voice to the illness narratives of lung transplant candidates. Results of this study illustrate that lung transplant candidates expressed a need to tell their personal story of waiting and to be heard. Recommendation from this study calls for healthcare providers to create the time to enable illness narratives of the suffering of waiting to be told. Narrative skills of listening to stories of emotional suffering would enhance how healthcare providers could attend to patients' stories and hear what is most meaningful in their lives.

    A 19-year-old man with cystic fibrosis, who was on extracorporeal membrane oxygenation, underwent bilateral lung transplantation from a donor with glioblastoma multiforme. Because the risk of tumor transmission from donor-related central nervous system malignancies remains unclear, the use of these extended donors remains controversial. In fact, there are few reports on the outcomes of lung transplantation from donors with central nervous system malignancy. This patient was critically ill with extracorporeal membrane oxygenation support before transplantation, but is well without any sign of malignancy 20 months after transplantation. PMID:19782299

    Gaucher disease (GD), a lysosomal storage disorder, may result in end-stage lung disease. We report successful bilateral lung transplantation in a 49-year-old woman with GD complicated by severe pulmonary hypertension and fibrotic changes in the lungs. Before receiving the lung transplant, the patient was undergoing both enzyme replacement therapy (imiglucerase) and triple pulmonary hypertension treatment (epoprostenol, bosentan, and sildenafil). She had a history of splenectomy, severe bone disease, and renal involvement, all of which were related to GD and considered as relative contraindications for a lung transplantation. In the literature, lung transplantation has been suggested for severe pulmonary involvement in GD but has been reported only once in a child. To our knowledge, until now, no successful procedure has been reported in adults, and no reports deal with the severe potential posttransplantation complications specifically related to GD.

    Controlled reperfusion of the transplanted lung has been used in nine consecutive patients to decrease manifestations of lung reperfusion injury. An extracorporeal circuit containing a roller pump, heat exchanger and leukodepleting filter is primed with substrate-enhanced reperfusion solution mixed with approximately 2000 ml of the patient's blood. This solution is slowly recirculated to remove leukocytes prior to reperfusion. When the pulmonary anastomoses are completed, the pulmonary artery is cannulated through the untied anastomosis using a catheter containing a pressure lumen for measurement of infusion pressure. An atrial clamp is left in place on the patient's native atrial cuff to decrease the risk of systemic air embolism during the brief period of reperfusion from the extracorporeal reservoir. During reperfusion, the water bath to the heat exchanger is kept at 35 degrees C and the flow rate for reperfusion solution is between 150 and 200 m/min, keeping the pulmonary artery pressure <14 mmHg. Eight of nine patients were ventilated on 40% inspired oxygen within a few hours of operation and 7/9 were extubated on or before postoperative day 1. Six of nine patients are long-term survivors.

    Lung transplant candidates and recipients have significant impairments in skeletal muscle mass, strength and function--individual measures of sarcopenia. Skeletal muscle dysfunction has been observed in the pre-transplant and post-transplant period and could have an important effect on transplant outcomes. A systematic review was performed to characterize the techniques used to study sarcopenia and assess the level of impairment throughout the transplant process. Electronic databases were searched (inception to July 2013) for prospective studies measuring at least 1 element of sarcopenia (muscle mass, strength, or function) in lung transplant patients. Eighteen studies were included, and study quality was assessed using the Downs and Black scale. A variety of measurements were used to evaluate sarcopenia in 694 lung transplant patients. Muscle mass in 7 studies was assessed using bioelectrical impedance (n = 4), computed tomography or magnetic resonance imaging (n = 2), or skin folds (n = 1), and was significantly reduced. Quadriceps strength was examined in 14 studies with computerized dynamometer (n = 10) and hand-held dynamometer (n = 4). Quadriceps strength was reduced in the pre-transplant period (mean range, 49%-86% predicted; n = 455 patients), further reduced immediately after transplant (51%-72%, n = 126), and improved beyond 3 months after transplant (58%-101%, n = 164). Only 2 studies measured lower extremity function (sit-to-stand test). A multitude of measurement techniques have been used to assess individual measures of sarcopenia, with reduced muscle mass and quadriceps strength observed in the pre-transplant and post-transplant period. Further standardization of measurement techniques is needed to assess the clinical effect of sarcopenia in lung transplantation.

    The aim of this review is to give an overview of the clinical circumstances presenting before lung transplant that may have negative repercussions on the long and short-term prognosis of the transplant. Methods for screening and diagnosis of common comorbidities with negative impact on the prognosis of the transplant are proposed, both for pulmonary and extrapulmonary diseases, and measures aimed at correcting these factors are discussed. Coordination and information exchange between referral centers and transplant centers would allow these comorbidities to be detected and corrected, with the aim of minimizing the risks and improving the life expectancy of transplant receivers.

    Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality and morbidity. Lung transplantation is one of the few treatments available for end-stage COPD with the potential to improve survival and quality of life. The selection of candidates and timing of listing present challenges, as COPD tends to progress fairly slowly, and survival after lung transplantation remains limited. Though the natural course of COPD is difficult to predict, the use of assessments of functional status and multivariable indices such as the BODE index can help identify which patients with COPD are at increased risk for mortality, and hence which are more likely to benefit from lung transplantation. Patients with COPD can undergo either single or bilateral lung transplantation. Although many studies suggest better long-term survival with bilateral lung transplant, especially in younger patients, this continues to be debated, and definitive recommendations about this cannot be made. Patients may be more susceptible to particular complications of transplant for COPD, including native lung hyperinflation, and development of lung cancer. PMID:26491282

    Isolated lung perfusion (ILP) has been examined and developed in lung transplantation and thoracic oncology research. In lung transplantation, ILP has been used to assess physiologic integrity of donor lungs after removal from the donor, and it has also been proposed as a method for active treatment and repair of injured unsuitable donor organs ex vivo. ILP is attractive as a concept to deliver high-dose chemotherapy to treat pulmonary metastatic disease, referred to as in vivo lung perfusion. This article focuses on the rationale, technical aspects, and experimental and clinical experience of in vivo lung perfusion. A perspective on the future application of these techniques is described.

    Bronchoscopy remains a pivotal diagnostic and therapeutic intervention in pediatric patients undergoing lung transplantation (LTx). Whether performed as part of a surveillance protocol or if clinically indicated, fibre-optic bronchoscopy allows direct visualization of the transplanted allograft, and in particular, an assessment of the patency of the bronchial anastomosis (or tracheal anastomosis following heart-lung transplantation). Additionally, bronchoscopy facilitates differentiation of infective processes from rejection episodes through collection and subsequent assessment of bronchoalveolar lavage (BAL) and transbronchial biopsy (TBBx) samples. Indeed, the diagnostic criteria for the grading of acute cellular rejection is dependent upon the histopathological assessment of biopsy samples collected at the time of bronchoscopy. Typically, performed in an out-patient setting, bronchoscopy is generally a safe procedure, although complications related to hemorrhage and pneumothorax are occasionally seen. Airway complications, including stenosis, malacia, and dehiscence are diagnosed at bronchoscopy, and subsequent management including balloon dilatation, laser therapy and stent insertion can also be performed bronchoscopically. Finally, bronchoscopy has been and continues to be an important research tool allowing a better understanding of the immuno-biology of the lung allograft through the collection and analysis of collected BAL and TBBx samples. Whilst new investigational tools continue to evolve, the simple visualization and collection of samples within the lung allograft by bronchoscopy remains the gold standard in the evaluation of the lung allograft. This review describes the use and experience of bronchoscopy following lung transplantation in the pediatric setting.

    Introduction: Pulmonary alveolar microlithiasis (PAM) is an autosomal recessive disease characterized by the deposition of phosphate and calcium in the alveoli. The disease progresses asymptomatically until later stages. When it becomes symptomatic, lung transplantations performed before the onset of right heart failure may improve life expectancy and quality. Here we present a case report concerning the very first Turkish PAM patient to have undergone lung transplantation surgery. Patient information: A 52 year-old female, Caucasian patient, already diagnosed with PAM in infancy, was admitted to the intensive care unit, diagnosed with pneumonia and hospitalized for 20 days. We decided to refer the patient to a specialized center for lung transplantation. Bilateral lung transplantation was performed in Vienna 14 months later and no recurrence was observed during the first postoperative year. Conclusion: Bilateral lung transplantation may improve both the life expectancy and the quality of life of PAM diagnosed patients with severe respiratory failure who do not suffer from right heart failure. The risk of recurrence should not be considered as a justifying reason to avoid transplantation as a treatment method. PMID:25165536

    Background. De novo and donor-derived invasive fungal infections (IFIs) contribute to morbidity and mortality in solid organ transplant (SOT) recipients. Reporting of donor-derived IFIs (DDIFIs) to the Organ Procurement Transplant Network has been mandated since 2005. Prior to that time no systematic monitoring of DDIFIs occurred in the United States. Case Presentation. We report a case of primary graft dysfunction in a 49-year-old male lung transplant recipient with diffuse patchy bilateral infiltrates likely related to pulmonary Sporothrix schenckii infection. The organism was isolated from a bronchoalveolar lavage on the second day after transplantation. Clinical and radiographic responses occurred after initiation of amphotericin B lipid formulation. Conclusion. We believe that this was likely a donor-derived infection given the early timing of the Sporothrix isolation after transplant in a bilateral single lung transplant recipient. This is the first case report of sporotrichosis in a lung transplant recipient. Our patient responded well to amphotericin induction therapy followed by maintenance therapy with itraconazole. The implications of donor-derived fungal infections and Sporothrix in transplant recipients are reviewed. Early recognition and management of these fungi are essential in improving outcomes.

    This case describes the technique of using dual Novalungs (a pumpless extracorporeal system) to bridge a patient with idiopathic pulmonary hypertension to bilateral lung transplantation. A 41-year old lady with idiopathic pulmonary hypertension (with a possible veno-occlusive element) presented with symptoms of end-stage heart and lung failure. This was refractory to medical management with iloprost, sildenafil and bosentan. The patient was placed on the urgent waiting list for lung transplantation and central pulmonary artery to left atrial Novalung insertion was performed. Local anaesthetic was given before performing peripheral cardiopulmonary bypass due to the high risk of cardiac arrest. Two days later, donor organs became available and the patient was taken for double-lung transplantation. The pulmonary artery cannula was removed leaving a large defect. This was then closed using a bovine pericardial patch. Due to the damaged right superior pulmonary vein from Novalung cannulation, cardioplegia was given to facilitate an open atrial anastomosis. After 13 days in the intensive therapy unit, she was transferred to the ward. There were no further complications and she has been discharged home. PMID:26819271

    Background Chest physiotherapy and high-frequency chest wall oscillation (HFCWO) are routinely used after lung transplant to facilitate removal of secretions. To date, no studies have been done to investigate which therapy is more comfortable and preferred by lung transplant recipients. Patients who have less pain may mobilize secretions, heal, and recover faster. Objectives To compare effects of HFCWO versus chest physiotherapy on pain and preference in lung transplant recipients. Methods In a 2-group experimental, repeated-measures design, 45 lung transplant recipients (27 single lung, 18 bilateral) were randomized to chest physiotherapy (10 AM, 2 PM) followed by HFCWO (6 PM, 10 PM; group 1, n=22) or vice versa (group 2, n=23) on postoperative day 3. A verbal numeric rating scale was used to measure pain before and after treatment. At the end of the treatment sequence, a 4-item patient survey was administered to assess treatment preference, pain, and effectiveness. Data were analyzed with χ(2) and t tests and repeated-measures analysis of variance. Results A significant interaction was found between mean difference in pain scores from before to after treatment and treatment method; pain scores decreased more when HFCWO was done at 10 AM and 6 PM (P =.04). Bilateral transplant recipients showed a significant preference for HFCWO over chest physiotherapy (11 [85%] vs 2 [15%], P=.01). However, single lung recipients showed no significant difference in preference between the 2 treatments (11 [42%] vs 14 [54%]). Conclusions HFCWO seems to provide greater decreases in pain scores than does chest physiotherapy. Bilateral lung transplant recipients preferred HFCWO to chest physiotherapy. HFCWO may be an effective, feasible alternative to chest physiotherapy. (American Journal of Critical Care. 2013;22:115-125).

    ABSTRACT Lung transplantation is a well-established treatment for patients with advanced lung disease. The evaluation of a candidate for transplantation is a complex task and involves a multidisciplinary team that follows the patient beyond the postoperative period. Currently, the mean time on the waiting list for lung transplantation in the state of São Paulo, Brazil, is approximately 18 months. For Brazil as a whole, data from the Brazilian Organ Transplant Association show that, in 2014, there were 67 lung transplants and 204 patients on the waiting list for lung transplantation. Lung transplantation is most often indicated in cases of COPD, cystic fibrosis, interstitial lung disease, non-cystic fibrosis bronchiectasis, and pulmonary hypertension. This comprehensive review aimed to address the major aspects of lung transplantation: indications, contraindications, evaluation of transplant candidates, evaluation of donor candidates, management of transplant recipients, and major complications. To that end, we based our research on the International Society for Heart and Lung Transplantation guidelines and on the protocols used by our Lung Transplant Group in the city of São Paulo, Brazil.

    Lung nodules after lung transplantation most often represent infection or post-transplant lymphoproliferative disorder in the allograft. Conversely, native lung nodules in single lung transplant recipients are more likely to be bronchogenic carcinoma. We present a patient who developed native lung cavitary nodules. Although malignancy was anticipated, evaluation revealed probable Phaeoacremonium parasiticum infection.

    Lung nodules after lung transplantation most often represent infection or post-transplant lymphoproliferative disorder in the allograft. Conversely, native lung nodules in single lung transplant recipients are more likely to be bronchogenic carcinoma. We present a patient who developed native lung cavitary nodules. Although malignancy was anticipated, evaluation revealed probable Phaeoacremonium parasiticum infection. Phaeoacremonium parasiticum is a dematiaceous fungus first described as a cause of soft tissue infection in a renal transplant patient. Lung nodules have not been previously described and this is the first case, to our knowledge, of P. parasiticum identified after lung transplantation. PMID:23279754

    Lobar torsion is well documented after pneumonectomy, but is very rare after lung transplant. To the best of our knowledge, this is the twelfth reported case of lobar torsion after lung transplant. In our case, bronchoscopies and chest radiographs were inconclusive; however, CT scan clearly demonstrated findings consistent with right middle lobe torsion. We review the literature and discuss the epidemiology, clinical presentation, imaging features, and treatment considerations for this condition. We also propose that if a clinical picture could be secondary to torsion and bronchoscopies and chest x ray are inconclusive that a CT scan should be obtained as soon as possible since early recognition increases the likelihood of being able to successfully detorse the lung and avoid lobectomy.

    Prone position ventilation (PPV) improves mortality in severe acute respiratory distress syndrome (ARDS), but outcomes following its use in lung transplant recipients are not known. We report the case of a 42-year-old Caucasian man who presented with severe ARDS from Bordetella pertussis, 5 years after bilateral sequential lung transplant for cystic fibrosis. He was managed with PPV for 22 days and had a prolonged ICU stay complicated by hypoxic ischemic optic neuropathy leading to blindness. Since his discharge from the ICU 6 months ago, his FEV1 has recovered to 47% predicted compared to his pre-ICU peak FEV1 of 85% predicted, suggesting recovery of lung function. This is the first report of optic nerve damage and vision loss in patients undergoing PPV. Our report also suggests that, in appropriately selected lung transplant recipients, severe hypoxemia could potentially be managed with prone ventilation. PMID:27051622

    In France, the higher frequency of pulmonary sample in organ donors and the enhancement of surgical and perioperative life support techniques, have increased the number procedures and the short term prognosis of lung transplantation (LT). In this setting, the classical contraindications of LT need to be reconsidered. In this article, some of the classical contraindication of LT are confronted to the experience acquired in other solid organ transplantations or from some LT centers. Specific situations such as LT in patients with previous cancer, HIV infection, viral hepatitis, nutritional disorders, acutely ill LT candidates and aging candidates are addressed. Surgical contraindications are not reviewed.

    A 29-year-old man underwent bilateral lung transplantation and received maintenance immunosuppressive therapy. He was readmitted 11 months later with symptoms of cough, sneezing, and rhinorrhea. The physical examination was normal. Laboratory results were significant for a reduction of FEV1 and an interstitial infiltrate on chest films. The patient had recently undergone bronchoscopy for rejection surveillance, and 2 days before admission the bronchoalveolar lavage cultures returned positive for respiratory syncytial virus. The patient was treated with aerosolized ribavirin with complete resolution of symptoms. Respiratory syncytial virus must now be included in the list of pathogens causing pneumonia in the lung transplant recipient. PMID:1540615

    We have employed multiple indicator dilution techniques (MID) in six patients after heart-lung transplantation to assess changes in the lung vascular permeability-surface area product for urea (PS). Serial PS values for the patients when normalized to the predicted total lung capacity (TLC) in liters, ranged between 1.04 and 6.27 ml/sec/TLC (patient 1), 0 and 2.76 ml/sec/TLC (patient 2), 0.59 and 2.88 ml/sec/TLC (patient 3), 0.13 and 1.23 ml/sec/TLC (patient 4). The elevated values for PS in patient 1 exceed the lethal range described by K.L. Brigham et al. (J. Clin. Invest. 72:339, 1983) for severe ARDS. This strongly suggests a severely increased lung microvascular permeability in this patient possibly secondary to rejection as indicated by endomyocardial biopsy. PS values for surviving patients 2-6 fell well below the corresponding lethal value for ARDS patients. We conclude that PS urea derived from MID provides an indicator of the status of lung microvascular integrity in heart-lung transplant recipients.

    2015-01-01

    Primary graft dysfunction (PGD) is a severe form of acute lung injury that is a major cause of early morbidity and mortality encountered after lung transplantation. PGD is diagnosed by pulmonary oedema with diffuse alveolar damage that manifests clinically as progressive hypoxemia with radiographic pulmonary infiltrates. Inflammatory and immunological response caused by ischaemia and reperfusion is important with regard to pathophysiology. PGD affects short- and long-term outcomes, the donor organ is the leading factor affecting these adverse ramifications. To minimize the risk of PGD, reduction of lung ischaemia time, reperfusion optimisation, prostaglandin level regulation, haemodynamic control, hormone replacement therapy, ventilator management are carried out; for research regarding donor lung preparation strategies, certain procedures are recommended. In this review, recent updates in epidemiology, pathophysiology, molecular and genetic biomarkers and technical developments affecting PGD are described. PMID:27366539

    Lung transplantation (LTx) has become an accepted treatment for carefully selected patients with end-stage lung disease. Critical care issues have gained importance concerning bridging of candidates by mechanical respiratory support and are involved in the care after transplantation. The nature of respiratory support varies from oxygen supply and noninvasive ventilation, to mechanical respiratory support either by mechanical ventilation and/or extracorporeal life support. Recent innovations in extracorporeal life support technology have resulted in its more widespread use. Retrospective studies have demonstrated promising outcomes in candidates on mechanical respiratory support as a bridge to lung transplantation. The role of mechanical respiratory support has influenced the selection criteria for LTx, although bridging remains technically and ethically challenging. Critical care is integral to manage and prevent postoperative complications of LTx. Primary graft dysfunction and prolonged mechanical ventilation are major obstacles to hospital survival after LTx. Clear evidence is lacking on how to ventilate and optimally manage patients after LTx. Prolonged extracorporeal life support after LTx may improve outcome in selected patients with a primary graft dysfunction. PMID:26953218

    Patients with cystic fibrosis have a higher risk of developing chronic respiratory infectious diseases. The Nocardia farcinica lung infection is rare in this group of patients, and there are limited publications about this topic. Its diagnosis is complex, due to the clinical and the radiology signs being non-specific. Identification of the agent responsible in the sputum culture is occasionally negative. It is a slow growing organism and for this reason treatment is delayed, which can lead to an increase in complications, hospitable stays, and mortality. A case is reported on a 26 year-old woman with cystic fibrosis and chronic lung colonization by Nocardia farcinica and Aspergillus fumigatus, on long-term treatment with ciprofloxacin, trimethoprim-sulfamethoxazole, and posaconazole, who was admitted to ICU after bilateral lung transplantation. The initial post-operative progress was satisfactory. After discharge, the patient showed a gradual respiratory insufficiency with new chest X-ray showing diffuse infiltrates. Initially, the agent was not seen in the sputum culture. Prompt and aggressive measures were taken, due to the high clinical suspicion of a Nocardia farcinica lung infection. Treatment with a combination of amikacin and meropenem, and later combined with linezolid, led to the disappearance of the lung infiltrates and a clinical improvement. In our case, we confirm the rapid introduction of Nocardia farcinica in the new lungs. The complex identification and the delay in treatment increased the morbimortality. There is a special need for its eradication in patients with lung transplant, due to the strong immunosuppressive treatment. PMID:25443661

Mediastinal and pericardial complications, in the form of constriction, are not common. We present 4 patients with constrictive pericarditis after lung transplantation and recommend that constrictive pericarditis be considered in the differential diagnosis in lung transplant recipients who present with signs and symptoms of systemic and pulmonary venous congestion.

    Breast and lung cancers are the most common primary neoplasms to manifest with choroidal metastases. The incidence of choroidal metastases from metastatic lung cancer was reported to be 2–6.7%. We report a case of bilateral choroidal metastasis from non-small cell lung cancer. A 59-year-old Caucasian female patient, never a smoker, was diagnosed with stage IV lung adenocarcinoma metastatic to the pleura, bones, and the brain. Her initial scan of the chest showed innumerable soft tissue nodules and mediastinal adenopathy compatible with metastatic disease. Her initial brain MRI showed numerous small enhancing lesions consistent with extensive disease. Unfortunately, during her follow-up visits, she presented with bulge on her left eye. Simultaneously, her follow-up chest scan showed increase in the size of the lung nodules. She continued to have a reasonable performance status at that time, except for mild increase in her dyspnea. The choroidal metastases require a multidisciplinary care and should be among the differential patients with malignancy who present with ocular symptoms. PMID:25295203

    The most common malignancy of the eye is metastatic tumors, with choroidal metastases being the majority of them. In women, breast cancer is the most common cause of orbital metastases, and in men, it is lung cancer. Despite the fact that there are efficient treatment options for orbital metastases, the benefit of procedures to detect choroidal metastases is debatable due to the quick progression and poor prognosis of lung cancer. In choroidal metastases resulting from lung cancer, patients are usually presented with decreased sight. Defects in the field of vision, flashes of light and floating bodies generally follow. Treatment options of choroidal metastases include many methods including laser photocoagulation, cryotherapy, chemotherapy, radiotherapy, surgical resection, enucleation and photodynamic therapy. There are reports emphasizing radiotherapy as the most efficient treatment option. In this case report, we sum up the case of a male patient presenting with blurry vision in both eyes, who was subsequently detected to have bilateral choroidal metastatic tumor and was diagnosed with primary lung adenocarcinoma.

    Patients who are excellent candidates for lung transplantation often die on the waiting list because they are too sick to survive until an organ becomes available. Improvements in lung transplant outcomes, patient selection, and artificial lung device technologies have made it possible to bridge these patients to successful life-saving transplantation. Extracorporeal life support (ECLS) should be tailored to minimize morbidity and provide the appropriate mode and level of cardiopulmonary support for each patient's physiologic requirements. Novel device refinements and further development of ECLS in an ambulatory and simplified manner will help maintain these patients in better condition until transplantation. PMID:21511087

    2014-01-01

    Background Idiopathic pulmonary fibrosis (IPF) is a distinct form of interstitial pneumonia with unknown origin and poor prognosis. Current pharmacologic treatments are limited and lung transplantation is a viable option for appropriate patients. The aim of this review was to summarize lung transplantation survival in IPF patients overall, between single (SLT) vs. bilateral lung transplantation (BLT), pre- and post Lung Allocation Score (LAS), and summarize wait-list survival. Methods A systematic review of English-language studies published in Medline or Embase between 1990 and 2013 was performed. Eligible studies were those of observational design reporting survival post-lung transplantation or while on the wait list among IPF patients. Results Median survival post-transplantation among IPF patients is estimated at 4.5 years. From ISHLT and OPTN data, one year survival ranged from 75% - 81%; 3-year: 59% - 64%; and 5-year: 47% - 53%. Post-transplant survival is lower for IPF vs. other underlying pre-transplant diagnoses. The proportion of IPF patients receiving BLT has steadily increased over the last decade and a half. Unadjusted analyses suggest improved long-term survival for BLT vs. SLT; after adjustment for patient characteristics, the differences tend to disappear. IPF patients account for the largest proportion of patients on the wait list and while wait list time has decreased, the number of transplants for IPF patients has increased over time. OPTN data show that wait list mortality is higher for IPF patients vs. other diagnoses. The proportion of IPF patients who died while awaiting transplantation ranged from 14% to 67%. While later transplant year was associated with increased survival, no significant differences were noted pre vs. post LAS implementation; however a high LAS vs low LAS was associated with decreased one-year survival. Conclusions IPF accounts for the largest proportion of patients awaiting lung transplants, and IPF is associated with

    Abstract The aim of the present study was to determine the distribution of lung blood in a modified bilateral Glenn procedure designed in our institute with lung perfusion scintigraphy. Sixteen consecutive patients who underwent modified bilateral Glenn operation from 2011 to 2014 were enrolled in the study. The control group consisted of 7 patients who underwent bidirectional Glenn shunt. Radionuclide lung perfusion scintigraphy was performed using Tc-99m-macro aggregated albumin (MAA) in all patients. For the patients in modified bilateral Glenn group, the time at which the radioactivity accumulation peaked did not differ significantly between the right and left lung field (t = 0.608, P = 0.554). The incidence of perfusion abnormality in each lung lobe also did not differ significantly (P = 0.426 by Fisher exact test). The radioactive counts were higher in the right lung than in the left lung, but the difference was not statistically significant (t = 1.502, P = 0.157). Radioactive perfusion in the lower lung field was significantly greater than that in the upper field (t = 4.368, P < 0.001). Compared with that in the bidirectional Glenn group, the ratio of radioactivity in the right lung to that in left lung was significantly lower in the modified bilateral Glenn group (t = 3.686, P = 0.002). Lung perfusion scintigraphy confirmed the benefit of the modified bilateral Glenn shunt with regard to more balanced blood perfusion in both lungs. PMID:27661042

    2016-01-01

    Lung transplantation has been performed worldwide and recognized as an effective treatment for patients with various end-stage lung diseases. Shortage of lung donors is one of the main obstacles in most of the countries, especially in Japan. Every effort has been made to promote organ donation during the past 20 years. In 2010, Japanese transplant low was revised so that the family of the brain dead donors can make a decision for organ donation. Since then, the number of cadaveric lung donor has increased by 5-fold. However, the average waiting time is still more than 800 days resulting in considerable number of deaths on the waiting list. Lung transplantation in the use of donation after cardiac death (DCD) has now been increasingly performed in Europe, Australia and North America with promising results. However, controlled death is not permitted in Japan making it difficult to accept this strategy. Use of marginal donors is one of the strategies for organ shortage. In Japan, the rate of lung usage is now well over 60% because of careful donor management by medical consultants and aggressive use of marginal donors. Living-donor lobar lung transplantation (LDLLT) has been developed to offset the mismatch between supply and demand for those patients awaiting cadaveric lung transplantation (CLT) and it is often the most realistic option for very ill patients. Between 1998 and 2015, lung transplantation has been performed in 464 patients (55 children, 419 adults) at 9 lung transplant centers in Japan. CLT was performed in 283 patients (61%) and LDLLT was performed in 181 patients (39%). The 5-year survival was 72.3% and 71.6%, respectively. Of note, only seven children received CLT. In conclusion, lung transplantation in Japan has grown significantly with excellent results but the shortage of cadaveric lung donor remains to be an important unsolved problem. LDLLT is often the only realistic option for very ill patients especially for children. PMID:27651939

    Unexpected lung cancer is sometimes found in explanted lungs. The objective of this study was to review these patients and their outcomes to better understand and optimize management protocols for lung transplant candidates with pulmonary nodules. Retrospective analysis of pretransplant imaging and clinicopathologic characteristics of patients who were found to have lung cancer in their explanted lungs was performed. From January 2003 to December 2012, 13 of 853 lung transplant recipients were found to have unexpected lung cancer in their explanted lung (1.52%). Of them, 9 cases were for interstitial lung disease (2.8%; 9/321 recipients) and 4 cases were for chronic obstructive pulmonary disease (1.57%; 4/255 recipients). The median period between computed tomographic scan and lung transplantation was 2.40 months (range: 0.5-19.2). On computed tomographic scan, only 3 cases were shown to possibly have a neoplasm by the radiologist. The staging of these lung cancers was as follows: 3 cases of IA, 1 case of IB, 5 cases of IIA, 1 case of IIIA, and 3 cases of IV. Of 13 cases, 9 died owing to cancer progression. On the contrary, only 1 stage I case with small cell lung cancer showed cancer recurrence. The median survival time was 339 days, and the 3-year survival rate was 11.0%. In conclusion, most of the patients with unexpected lung cancer showed poor prognosis except for the early-stage disease. The establishment of proper protocol for management of such nodules is important to improve the management of candidates who are found to have pulmonary nodules on imaging. PMID:26074103

    Among solid organs, transfer of peanut allergy from donor to recipient has been implicated after liver transplantation. We report the first case in which such transfer occurred after a lung transplant. A 42-year-old woman with history of sarcoidosis underwent a successful bilateral lung transplant from a donor who died from anaphylactic shock after eating peanut-related food. Seven months later, she ate a peanut butter cookie at a transplant support group meeting. Immediately thereafter, she developed an anaphylactic reaction, but survived with prompt treatment. During subsequent follow-up, she could recall three prior episodes of wheezing and difficulty breathing after eating peanut-related foods. The first episode occurred 4 days after the transplant. Prior to her transplant, she never had problems eating peanuts. Skin-prick testing confirmed peanut sensitization. She avoided peanuts and, although her skin-prick test became negative, she still manifested peanut allergy when formally challenged orally with the food. She was advised to continue abstaining from all peanut-related foods. This case emphasizes the importance of considering donor allergy transfer when caring for all solid-organ transplant recipients in order to avoid a life-threatening event.

Methods We describe trends in lung transplantation during 1996–2014 for recipients with a primary diagnosis of CWP or pneumoconiosis unspecified, and we summarize recipient characteristics and estimate survival. Results A total of 47 transplants were included; nearly three-quarters were performed during 2008–2014. All recipients were male, 96% were white, and the mean age was 56 years. Mean FEV1% was 35%; mean FVC% was 53%. Mean time on a waitlist was 155 days, and 60% of transplants were bilateral. Median survival was 3.7 years. Conclusions These transplants reflect the use of a scarce resource for an entirely preventable disease, and highlight the need for enhanced efforts to reduce coal mine dust exposures. PMID:26725917

Methods: The rat orthotopic lung transplantation model was established to perform the level of autophagy in the cold I/R injury in this study. The pretreatment of inhibitor (3-Methyladenine [3-MA]) and activator (rapamycin [RAPA]) of autophagy were performed to assess the role of autophagy in the cold I/R injury following lung transplantation in rats. Results: After lung transplantation, the autophagy, lung cell apoptosis and lung injury were aggravated and peaked at 6 h following the transplantation. The inhibition of autophagy by 3-MA induced downregulated of autophagy, decreased cell apoptosis. Meanwhile, the lung injury, which was indicated by calculating the peak inspiratory pressure (PIP), pulmonary vein blood gas analysis (PO2) and ratio of wet to dry in lung (W/D), was ameliorated after treatment with 3-MA. The activation of autophagy by RAPA causing the upregulated of autophagy and apoptosis of lung cells, and enhanced the lung injury. Conclusion: All the results suggested that the autophagy was involved in the cold I/R injury in lung transplantation model, and played a potential role on the regulation of I/R injury after lung transplantation.

    Palmar hyperhidrosis (PH) is a common disorder in the oriental subtropical area. There have been many therapeutic methods, such as: oral medication, local treatment and traditional surgical operation, but none of them has proved entirely satisfactory. Since the development of video endoscopic surgery, transthoracic endoscopic sympathectomy has been increasing day by day. This study consisted of 124 PH patients under alternative one lung ventilation anesthesia for bilateral thoracoscopic laser sympathectomy. The age of patients ranged from 13 to 64 years, male 45 and female 79. The average anesthesia duration was 60 min. We used glycopyrrolate 0.03 mg/kg, decardon 1 mg/10 kg for premedication. Induction was with fentanyl 0.07 ml/kg, atracurium 0.6 mg/kg and thiopental 4 mg/kg. Maintenance was with isoflurane in 3L/min. oxygen inhalation. The alternative one lung ventilation anesthesia was achieved with double-lumen endobronchial tube. Fr 37, Fr 35, Fr 28 Sheridan Lt. double-lumen bronchial tube were used depending upon the sex and fudgement of the individual patient. All patients tolerated the procedure well so that sympathectomy could be performed smoothly and uneventfully. Immediately after the operation, a transient mild to moderate degree of difficult breathing and substernal discomfort were experienced in the majority of patients. These suffering often relieved spontaneously or with some common analgesic.

    Infection with Burkholderia species is typically considered a contraindication leading to transplantation in cystic fibrosis (CF). However, the risks posed by different Burkholderia species on transplantation outcomes are poorly defined. We present the case of a patient with CF who underwent lung transplantation due to a severe respiratory failure from chronic airways infection with Burkholderia pyrrocinia (B. cepacia genomovar IX) and pan-resistant Pseudomonas aeruginosa. The postoperative course was complicated by recurrent B. pyrrocinia infections, ultimately lea ding to uncontrollable sepsis and death. This is the first case report in CF of Burkholderia pyrrocinia infection and lung transplantation, providing further evidence of the high risk nature of the Burkholderia species.

    Although extracorporeal membrane oxygenation (ECMO) has been used frequently as a bridge to primary lung transplantation, active centers are conservative with this approach in patients requiring redo lung transplantation. We report the use of extracorporeal carbon dioxide removal, using the Hemolung respiratory assist system, as a prolonged bridge to lung transplantation, and the first use of the Hemolung as a bridge to redo lung transplantation. Hemolung support improved the patient's clinical status and allowed redo lung transplantation.

    Seventeen days after double lung transplantation, a 56-year-old patient with idiopathic pulmonary fibrosis developed respiratory distress. Imaging revealed bilateral pulmonary infiltrates with pleural effusions and physical examination demonstrated sternal instability. Broad-spectrum antibacterial and antifungal therapy was initiated and bilateral thoracotomy tubes were placed. Both right and left pleural cultures grew a mold subsequently identified as Scopulariopsis brumptii. The patient underwent pleural irrigation and sternal debridement three times but pleural and wound cultures continued to grow S. brumptii. Despite treatment with five antifungal agents, the patient succumbed to his illness sixty-seven days after transplantation. Autopsy confirmed the presence of markedly invasive fungal disease and pleural rind formation. The patient’s organ donor had received bilateral thoracostomy tubes during resuscitation in a wilderness location. There were no visible pleural abnormalities at the time of transplantation. However, the patient’s clinical course and the location of the infection, in addition to the lack of similar infection in other organ recipients, strongly suggest that Scopulariopsis was introduced into the pleural space during pre-hospital placement of thoracostomy tubes. This case of lethal infection transmitted through transplantation highlights the unique risk of using organs from donors who are resuscitated in an outdoor location. PMID:25376207

    Bilateral venous thrombosis due to underlying malignancy is a rare entity. It is worthy to search for malignancy in patients of bilateral venous gangrene. Our patient presented with severe bilateral leg pain as a result of venous gangrene. There was associated left sided massive pleural effusion with scalp nodule. Fine needle aspiration cytology of scalp nodule revealed metastatic squamous cell carcinoma and fiber optic bronchoscopy guided biopsy from growth at left upper lobe bronchus confirmed the case as squamous cell carcinoma lung. It was rare for squamous cell carcinoma lung to present as bilateral venous gangrene with anticardiolipin antibody negative. PMID:24455526

    A 47-year-old woman underwent bilateral lung transplantation for nonspecific interstitial pneumonitis and received donor lungs from a 12-year-old patient with a known peanut allergy. Post-transplant, the patient experienced four anaphylaxis-like reactions. A skin prick test to peanut was initially positive; however, it steadily declined over serial assessments and reverted to negative one year post-transplant. The patient subsequently had a negative oral peanut challenge. Transfer of food allergy post-transplantation is theorized to occur via transfer of donor B lymphocytes producing peanut-specific immunoglobulin E into the circulation of the recipient. An alternate mechanism proposes passive transfer of immunoglobulin E-sensitized mast cells and⁄or basophils within the transplanted tissue that subsequently migrate into recipient tissues. The gradual decline in the magnitude of the peanut skin prick test and its return to negative over the course of one year supports the gradual depletion of sensitized cells in the recipient (B lymphocytes and, possibly, mast cells), and supports the initial passive transfer of sensitized cells from donor tissue during transplantation. This should be considered when donor organs are obtained from allergic individuals.

    Bilateral forearm and hand transplantation poses unique challenges especially in the setting of bilateral lower limb amputations. A 57-yr-old man with bilateral transradial amputations and bilateral transtibial amputations after remote streptococcal sepsis was admitted for inpatient rehabilitation because of severe debilitation after forearm/hand transplantations. He required 6 wks of bed rest to allow the healing of the allografts but developed profound deconditioning. Because of weight-bearing precautions and other complications such as femoral neurapraxia, he required the use of body weight-support apparatus to ambulate with lower limb prostheses, keeping weight off the allografts. He progressed to walking 600 ft using a platform-wheeled walker at a modified independent level, to climbing four stairs with minimal assistance, and to being able to toss a small football using his right hand, indicating improved flexor function in this hand. Tacrolimus levels were maintained without clinical evidence of acute rejection. Through an individualized therapy regimen, careful monitoring of the allografts and dedicated support staff, rehabilitation training of a previous quadrimembral amputee after bilateral hand transplantations can be successful.

    Modifications in recipient and donor criteria and innovations in donor management hold promise for increasing rates of lung transplantation, yet availability of donors remains a limiting resource. Imaging is critical in the work-up of donor and recipient including identification of conditions that may portend to poor posttransplant outcomes or necessitate modifications in surgical technique. This article describes the radiologic principles that guide selection of patients and surgical procedures in lung transplantation.

    Effectiveness of pulmonary rehabilitation in patients with chronic obstructive lung diseases, cystic fibrosis, and interstitial lung disease is well documented but little is known about the results of pulmonary rehabilitation in patients referred for lung transplantation. The purpose of this study is to prospectively examine the efficacy of Nordic walking, a low cost, accessible, and proven beneficial form of physical exercise, as a form of pulmonary rehabilitation in patients referred for lung transplantation. Twenty-two male patients referred for lung transplantation at the Department of Lung Diseases and Tuberculosis in Zabrze, Poland, were invited to take part in the study. The rehabilitation program, which was conducted for 12 weeks, was based on Nordic walking exercise training with ski poles. Lung function tests (FVC, FEV1), mobility (6 min walking test (6MWT)), rating of dyspnea (Oxygen Cost Index, MRC and Baseline Dyspnea Index), and quality of life assessments (SF-36) were performed before and after the completion of the exercise program. No adverse events were observed after completing the pulmonary rehabilitation program in patients referred for lung transplantation. After 12 weeks of pulmonary rehabilitation with Nordic walking we observed a significant increase in the mean distance walked in the 6MWT (310.2 m vs. 372.1 m, p < 0.05). The results of lung function tests also showed improvement in FVC. There were no significant differences in the perception of dyspnea before and after completing the rehabilitation program. General health and quality of life questionnaire (SF-36) showed improvement in the domain of social functioning (p < 0.05). In conclusion, pulmonary rehabilitation with a Nordic walking program is a safe and feasible physical activity in end-stage lung disease patients referred for lung transplantation and results in improvements in patients' mobility and quality of life.

    The present guidelines have been prepared with the consensus of at least one representative of each of the hospitals with lung transplantation programs in Spain. In addition, prior to their publication, these guidelines have been reviewed by a group of prominent reviewers who are recognized for their professional experience in the field of lung transplantation. Within the following pages, the reader will find the selection criteria for lung transplantation candidates, when and how to remit a patient to a transplantation center and, lastly, when to add the patient to the waiting list. A level of evidence has been identified for the most relevant questions. Our intention is for this document to be a practical guide for pulmonologists who do not directly participate in lung transplantations but who should consider this treatment for their patients. Finally, these guidelines also propose an information form in order to compile in an organized manner the patient data of the potential candidate for lung transplantation, which are relevant in order to be able to make the best decisions possible.

    Kidney failure after lung transplantation is a risk factor for chronic kidney disease. Calcineurin inhibitors are immunosuppressants which play a major role in terms of postoperative kidney failure after lung transplantation. We report our preliminary experience with the anti-interleukin-2 monoclonal antibody Basiliximab utilized as a "calcineurin inhibitor-free window" in the setting of early postoperative kidney failure after lung transplantation. Between 2012 and 2015 nine lung transplant patients who developed kidney failure for more than 14 days were included. Basiliximab was administrated in three doses (Day 0, 4, and 20) whilst Tacrolimus was discontinued or reduced to maintain a serum level between 2 and 4 ng/mL. Baseline glomerular filtration rate pre transplant was normal for all patients. Seven patients completely recovered from kidney failure (67%, mean eGFR pre and post Basiliximab: 42.3 mL/min/1.73 m(2) and 69 mL/min/1.73 m(2)) and were switched back on Tacrolimus. Only one of these patients still needs ongoing renal replacement therapy. Two patients showed no recovery from kidney failure and did not survive. Basiliximab might be a safe and feasible therapeutical option in patients which are affected by calcineurin inhibitor-related kidney failure in the early post lung transplant period. Further studies are necessary to confirm our preliminary results.

    Liver disease develops in one-third of patients with cystic fibrosis (CF). It is rare for liver disease to have its onset after 20 years of age. Lung disease, however, is usually more severe in adulthood. A retrospective analysis was performed on nine patients. Three patients required lung transplantation approximately a decade after liver transplant, and another underwent combined liver and lung transplants. Four additional patients with liver transplants are awaiting assessment for lung transplants. One patient is awaiting combined liver and lung transplants. With increased survival in CF, several patients may require more than single organ transplantation. PMID:27405894

    2014-11-01

    Ex vivo lung perfusion (EVLP) has emerged as a new technique for assessing and potentially reconditioning human donor lungs previously unacceptable for clinical transplantation with the potential to dramatically push the limits of organ acceptability. With the recent introduction of portable EVLP, a new era in lung preservation may be upon us with the opportunity to also limit organ ischaemic times and potentially improve the outcome of donor lungs already deemed acceptable for transplantation. It took over half a century for the technique to evolve from basic theory to semi-automated circuits fit for clinical use that are now rapidly being adopted in transplant centres across the globe. With this field in constant evolution and many unanswered questions remaining, our review serves as an update on the state of the art of EVLP in clinical lung transplantation.

    We describe a novel technique of pumpless extracorporeal life support in four patients with cardiogenic shock due to end-stage pulmonary hypertension (PH) including patients with veno-occlusive disease (PVOD) using a pumpless lung assist device (LAD). The device was connected via the pulmonary arterial main trunk and the left atrium, thereby creating a septostomy-like shunt with the unique addition of gas exchange abilities in parallel to the lung. Using this approach, all four patients were successfully bridged to bilateral lung transplantation and combined heart-lung transplantation, respectively. Although all patients presented in cardiogenic shock, hemodynamic unloading of the right ventricle using the low-resistance LAD stabilized the hemodynamic situation immediately so that no pump support was subsequently required.

    We present a case of synchronous bilateral inoperable lung cancer which required treatment with external beam radiotherapy to a radical dose. Intensity-modulated radiotherapy (IMRT) was used. More conformal dose distribution within the planning target volume was obtained using IMRT than the conventional technique. Dose–volume constraints defined for the lungs were met. Treatment was subsequently delivered using a seven-field IMRT plan. The patient remains alive and disease-free 48 months after the completion of radiotherapy. IMRT can be considered an effective treatment for synchronous bilateral lung cancer. PMID:21937610

    The appropriate selection of lung transplant recipients is an important determinant of outcomes. This consensus document is an update of the recipient selection guidelines published in 2006. The Pulmonary Council of the International Society for Heart and Lung Transplantation (ISHLT) organized a Writing Committee of international experts to provide consensus opinion regarding the appropriate timing of referral and listing of candidates for lung transplantation. A comprehensive search of the medical literature was conducted with the assistance of a medical librarian. Writing Committee members were assigned specific topics to research and discuss. The Chairs of the Writing Committee were responsible for evaluating the completeness of the literature search, providing editorial support for the manuscript, and organizing group discussions regarding its content. The consensus document makes specific recommendations regarding the timing of referral and of listing for lung transplantation. These recommendations include discussions not present in previous ISHLT guidelines, including lung allocation scores, bridging to transplant with mechanical circulatory and ventilator support, and expanded indications for lung transplantation. In the absence of high-grade evidence to support decision making, these consensus guidelines remain part of a continuum of expert opinion based on available studies and personal experience. Some positions are immutable. Although transplant is rightly a treatment of last resort for end-stage lung disease, early referral allows proper evaluation and thorough patient education. Subsequent waiting list activation implies a tacit agreement that transplant offers a significant individual survival advantage. It is both the challenge and the responsibility of the transplant community globally to ensure organ allocation maximizes the potential benefits of a scarce resource, thereby achieving that advantage.

    Outcomes after heart and lung transplants have improved, and many recipients survive long enough to develop secondary renal failure, yet remain healthy enough to undergo kidney transplantation. We used national data reported to United Network for Organ Sharing (UNOS) to evaluate outcomes of 568 kidney after heart (KAH) and 210 kidney after lung (KAL) transplants performed between 1995 and 2008. Median time to kidney transplant was 100.3 months after heart, and 90.2 months after lung transplant. Renal failure was attributed to calcineurin inhibitor toxicity in most patients. Outcomes were compared with primary kidney recipients using matched controls (MC) to account for donor, recipient and graft characteristics. Although 5-year renal graft survival was lower than primary kidney recipients (61% KAH vs. 73.8% MC, p < 0.001; 62.6% KAL vs. 82.9% MC, p < 0.001), death-censored graft survival was comparable (84.9% KAH vs. 88.2% MC, p = 0.1; 87.6% KAL vs. 91.8% MC, p = 0.6). Furthermore, renal transplantation reduced the risk of death compared with dialysis by 43% for KAH and 54% for KAL recipients. Our findings that renal grafts function well and provide survival benefit in KAH and KAL recipients, but are limited in longevity by the general life expectancy of these recipients, might help inform clinical decision-making and allocation in this population.

    The differential diagnoses of a cavitary lung lesion in renal transplant recipients would include infection, malignancy and less commonly inflammatory diseases. Bacterial infection, Tuberculosis, Nocardiosis, fungal infections like Aspergillosis and Cryptococcosis need to be considered in these patients. Pulmonary cryptococcosis usually presents 16-21 mo after transplantation, more frequently in patients who have a high level of cumulative immunosuppression. Here we discuss an interesting patient who never received any induction/anti-rejection therapy but developed both BK virus nephropathy as well as severe pulmonary Cryptococcal infection after remaining stable for 6 years after transplantation. This case highlights the risk of serious opportunistic infections even in apparently low immunologic risk transplant recipients many years after transplantation. PMID:27358792

    Introduction The use of extracorporeal membrane oxygenation (ECMO) is considered a risk factor for, or even a potential contraindication to, lung transplantation. However, only a few pediatric cases have been described thus far. Case Presentation A 9-year-old boy with idiopathic pulmonary arterial hypertension developed cardiac arrest after the insertion of a central catheter. ECMO was used as a bridge to lung transplantation. However, after prolonged resuscitation, he developed medullary ischemia and medullary syndrome. After 6 weeks of ECMO and triple combination therapy for pulmonary hypertension, including continuous intravenous prostacyclin, he was weaned off support, and after 2 weeks, bilateral lung transplantation was performed. At 4 years post-transplant, he has minimal problems. The medullary syndrome has also alleviated. He is now back to school and can walk with aids. Conclusions Increasing evidence supports the use of ECMO as a bridge to LT, reporting good outcomes. In the modern era of PAH therapy, it is feasible to use prolonged ECMO support as a bridge to lung transplant, with the aim of weaning off this support; however, its use requires more experience and knowledge of long-term outcomes.

    We report on the to date largest recovery of 11 organs from a single deceased donor with the transplantation of face, bilateral upper extremities, heart, 1 lung, liver (split for 2 recipients), kidneys, pancreas, and intestine. Although logistically challenging, this case demonstrates the feasibility and safety of the recovery of multiple thoracic and abdominal organs with multiple vascular composite allotransplants and tissues. Our experience of 8 additional successful multiple vascular composite allotransplants, thoracic, and abdominal organ recoveries suggests that such procedures are readily accomplishable from the same deceased donor.

    Background: Lung diseases are one of the major causes of morbidity and mortality after renal transplantation. The aim of the study is to define the risk factors for infectious and noninfectious pulmonary complications in kidney transplant patients. Materials and Methods: We prospectively studied 267 patients after renal transplantation. The kidney recipients were followed-up for the development of pulmonary complications for a period of 7 years. Different noninvasive and invasive diagnostic tests were used in cases suspected of lung disease. Results: The risk factors associated with the development of pulmonary complications were diabetes mellitus (odds ratio [OR] = 4.60; P = 0.001), arterial hypertension (OR = 1.95; P = 0.015), living related donor (OR = 2.69; P = 0.004), therapy for acute graft rejection (OR = 2.06; P = 0.038), immunosuppressive regimens that includes mycophenolate (OR = 2.40; P = 0.011), azathioprine (OR = 2.25; P = 0.023), and tacrolimus (OR = 1.83; P = 0.041). The only factor associated with the lower risk of complications was a positive serology test for Cytomegalovirus of the recipient before transplantation (OR = 0.1412; P = 0.001). Conclusion: The risk factors can be used to identify patients at increased risk for posttransplant lung diseases. Monitoring of higher-risk patients allow timely diagnosis and early adequate treatment and can reduce the morbidity and mortality after renal transplantation. PMID:26958045

    Pulmonary resection after lung transplantation in end-stage cystic fibrosis presents unique challenges, and scant literature exists to guide physicians. We retrospectively reviewed 78 transplants for cystic fibrosis performed between 2003 and 2008. Fourteen patients underwent posttransplantation pulmonary resection. We analyzed the indications, surgical procedures, outcomes, and survival. Three pneumonectomies, 4 lobectomies, and 11 wedge resections were carried out. We identified 2 groups based on indication: a diagnostic group, and a therapeutic group of patients in whom the indications were septic native lung in 2, allograft infection in 2, lobar torsion in 2, pulmonary infarction in 2, and size mismatch in 4. The mean intensive care unit and hospital stays were 29 and 50 days, respectively. Four (28.57%) patients died during follow-up, including 2 who underwent pneumonectomy; 10 (71.43%) are still alive. Survival was 43.43 ± 8.06 months, and it was not significantly different from that in cystic fibrosis patients who had lung transplantation without pulmonary resection. Pulmonary resection following lung transplantation in cystic fibrosis patients showed acceptable survival and surgical risk, but metachronous pneumonectomy was associated with higher mortality.

    The unilateral rupture of the triceps brachii tendon is a rare lesion representing 1% of all tendon injuries. The most common causes are the result of a contraction against resistance (especially weightlifters) and direct trauma. It has also been associated with systemic diseases such as diabetes mellitus, chronic renal failure, secondary hyperparathyroidism, and use of systemic corticosteroids. Simultaneous bilateral rupture of the triceps tendons is less frequent and has been described in association with chronic metabolic disorders, especially in those patients on hemodialysis. This paper presents a case of bilateral triceps tendon rupture of a 36-year-old woman with renal transplantation secondary to chronic renal failure. Early surgical repair was performed using a bone tunnel technique with a nonabsorbable suture. Clinically active extension with 135 degrees of range of motion was achieved. PMID:26366314

    Disseminated phaeohyphomycoses are rare infections caused by dematiaceous fungi. Ochroconis gallopavum is a neurotropic dematiaceous mold responsible for life-threatening respiratory and central nervous system infections in domestic poultry and in immunologically compromised humans. The world literature describes only 13 previous O gallopavum infections in solid organ transplant recipients. We report herein an O gallopavum phaeohyphomycosis with involvement of skin in a transplant recipient. A 69-year-old white man with a history of bilateral lung transplantation 6 years ago presented with acute onset of severe respiratory distress. Chest X-ray showed no evidence of pneumonia. Lung function showed bronchiolitis obliterans syndrome. Excision biopsy was performed because of a suspected pigmented basal cell carcinoma. Histopathology revealed dermal granulomatous dermatitis, focally suppurative, dominated by epitheloid cells with brownish round fungi. Further microbiological work-up of the biopsy specimen subsequently revealed O gallopavum as the causative organism. No brain involvement was observed. Antimycotic therapy with voriconazole 200 mg twice a day was immediately initiated and the patient was treated for 3 months. Additional intravenous therapy with tobramycin and imipenem was started upon detection of Enterobacter clocae and Enterococci in the sputum. The patient recovered during the next few weeks and was discharged on day 26. PMID:23146522

Hand transplantation is a labor-intensive and time-intensive process and can be conceptualized into distinct phases that include (1) patient selection and preoperative preparation, (2) technical execution of the procedure, and (3) postoperative rehabilitation and follow-up. The advent of technological innovations, such as 3D printing technology, novel implant technology, as well as innovative imaging technology, such as functional magnetic resonance imaging have the potential of favorably affecting all phases of this process, thus contributing to improved outcomes.

    Lung transplantation has become an established treatment for end-stage pulmonary failure refractory to medical management. However, the scarcity of lung grafts and the growing number of candidates has led to an increase in deaths among patients on waiting lists. Despite improvements in donor management, organ preservation, and the use of marginal and cardiac death donors, only about 20% of candidate lungs are currently being transplanted. A new ex vivo "reconditioning" technique is opening up new perspectives. Indeed, a significant number of rejected lungs can now be retrieved and transplanted with acceptable results. Given the longer storage times provided by this technique, transplantation can be programmed, with better surgical efficiency. A new mobile organ-care machine is currently under evaluation. In near future, a pilot laboratory will be created and dedicated to ex vivo reconditionning of all lung grafts before transplantation and grafts will be sent to lung transplant centers after immunologic cross-matching.

    Donor-specific HLA antibodies (DSA) have an adverse effect on short-term and long-term lung transplant outcomes. We implemented a perioperative strategy to treat DSA-positive recipients, leading to equivalent rejection and graft survival outcomes. Pretransplant DSA were identified to HLA-A, B, C, DR and DQ antigens. DSA-positive patients were transplanted if panel reactive antibody (PRA) ≥30% or medically urgent and desensitized with perioperative plasma exchange, intravenous immune globulin, antithymocyte globulin (ATG), and mycophenolic acid (MPA). PRA-positive/DSA-negative recipients received MPA. Unsensitized patients received routine cyclosporine, azathioprine and prednisone without ATG. From 2008-2011, 340 lung-only first transplants were performed: 53 DSA-positive, 93 PRA-positive/DSA-negative and 194 unsensitized. Thirty-day survival was 96 %/99%/96% in the three groups, respectively. One-year graft survival was 89%/88%/86% (p = 0.47). DSA-positive and PRA-positive/DSA-negative patients were less likely to experience any ≥ grade 2 acute rejection (9% and 9% vs. 18% unsensitized p = 0.04). Maximum predicted forced expiratory volume (1 s) (81%/74%/76%, p = NS) and predicted forced vital capacity (81%/77%/78%, respectively, p = NS) were equivalent between groups. With the application of this perioperative treatment protocol, lung transplantation can be safely performed in DSA/PRA-positive patients, with similar outcomes to unsensitized recipients.

    Scedosporium is an important pathogen in cystic fibrosis (CF) and post-transplant but rarely causes invasive infection. Treatment remains challenging, particularly due to inherent resistance to multiple antifungal agents. We present a young man with CF who developed invasive sternal and rib infection 10-months following lung transplant. The infection has been clinically and radiologically cured with extensive surgery and triazole therapy. This case highlights the importance of adjunctive surgery in addition to prolonged triazole treatment to manage invasive Scedosporium infections in immunosuppressed patients. PMID:27595059

    Gastroesophageal reflux disease (GERD) in lung transplant recipients has gained increasing attention as a factor in allograft failure. There are few data on the impact of fundoplication on survival or lung function, and less on its effect on symptoms or quality of life. Patients undergoing fundoplication following lung transplantation from 1999 to 2005 were included in the study. Patient satisfaction, changes in GERD symptoms, and the presence of known side effects were assessed. The effect on lung function, body mass index, and rate of progression to the bronchiolitis obliterans syndrome (BOS) were recorded. Twenty-one patients (13 males), in whom reflux was confirmed on objective criteria, were included, with a mean age of 43 years (range 20-68). Time between transplantation and fundoplication was 768 days (range 145-1524). The indication for fundoplication was suspected microaspiration in 13 and symptoms of GERD in 8. There was one perioperative death, at day 17. There were three other late deaths. Fundoplication did not appear to affect progression to BOS stage 1, although it may have slowed progression to stage 2 and 3. Forced expiratory volume-1% predicted was 72.9 (20.9), 6 months prior to fundoplication and 70.4 (26.8), six months post-fundoplication, P= 0.33. Body mass index decreased significantly in the 6 months following fundoplication (23 kg/m(2) vs. 21 kg/m(2), P= 0.05). Patients were satisfied with the outcome of the fundoplication (mean satisfaction score 8.8 out of 10). Prevalence of GERD symptoms decreased significantly following surgery (11 of 14 vs. 4 of 17, P= 0.002). Fundoplication does not reverse any decline in lung function when performed at a late stage post-lung transplantation in patients with objectively confirmed GERD. It may, however, slow progression to the more advanced stages of BOS. Reflux symptoms are well controlled and patients are highly satisfied.

    The aim of the present study was to determine the distribution of lung blood in a modified bilateral Glenn procedure designed in our institute with lung perfusion scintigraphy. Sixteen consecutive patients who underwent modified bilateral Glenn operation from 2011 to 2014 were enrolled in the study. The control group consisted of 7 patients who underwent bidirectional Glenn shunt. Radionuclide lung perfusion scintigraphy was performed using Tc-99m-macro aggregated albumin (MAA) in all patients. For the patients in modified bilateral Glenn group, the time at which the radioactivity accumulation peaked did not differ significantly between the right and left lung field (t = 0.608, P = 0.554). The incidence of perfusion abnormality in each lung lobe also did not differ significantly (P = 0.426 by Fisher exact test). The radioactive counts were higher in the right lung than in the left lung, but the difference was not statistically significant (t = 1.502, P = 0.157). Radioactive perfusion in the lower lung field was significantly greater than that in the upper field (t = 4.368, P < 0.001). Compared with that in the bidirectional Glenn group, the ratio of radioactivity in the right lung to that in left lung was significantly lower in the modified bilateral Glenn group (t = 3.686, P = 0.002). Lung perfusion scintigraphy confirmed the benefit of the modified bilateral Glenn shunt with regard to more balanced blood perfusion in both lungs. PMID:27661042

    After single lung transplantation for emphysema native lung hyperinflation is a common complication that may cause respiratory failure. Herein we have reported satisfactory bronchoscopic lung volume reduction in a left single-lung transplant recipient with native lung hyperinflation, who suffered from Medical Research Council (MRC) class 3 dyspnea and chest pain. Three endobronchial valves (Zephyr; Emphasys Medical, Redwood, Calif, United States) were placed into the segmental bronchi of the right upper lobe, using videobronchoscopy under general anesthesia. Postoperative chest computed tomography revealed subsegmental atelectasis in that lobe. The clinical benefit was an improved MRC dyspnea class from 3 to 2, which was still present at 4 months after the procedure, although there were no remarkable changes in spirometric parameters.

    Thrombotic microangiopathy (TMA) is a rare complication associated with the use of calcineurin inhibitors in lung transplantation, irrespective of the underlying disease of the graft recipient. It usually occurs in incomplete forms, complicating and delaying diagnosis until damage is already irreversible. It is unrelated to time from transplantation and often presents with concomitant infection, which tends to confound diagnosis. The cases discussed here have a common causative agent and all present with concomitant infection. Treatment recommendations have changed in recent years with the introduction of plasmapheresis or, more recently, the availability of the antibody eculizumab. Notwithstanding, the most cost-effective measure is withdrawal or switching of the calcineurin inhibitor. TMA is an underdiagnosed clinical entity that should be considered in the management of transplantation patients.

    A paperless electronic spirometer/diary instrument has been employed in a home monitoring programme for lung and heart-lung transplant patients at the University of Minnesota. The monitoring programme is part of a long term study to develop a system which will detect the earliest signs of developing rejection or infection in the transplanted organs. It is based on patient daily self-measurements of standard spirometry, vital signs, and symptoms recorded at home and transmitted weekly to the study data center over the telephone using a modern built into the instrument. This report summarizes adherence behaviour for 41 subjects enrolled in the study over a 12 month period. The number of subjects from whom home data has been received each week was used to measure adherence at the subject level. The number of records received each week measured adherence at the daily recording level. A data record consists of a daily set of spirometry, vital signs, and symptom values from a given subject. Approximately 82% of subjects transmitted records each week, over the 52 week review period. There was an average of 4.5 records received each week from each subject. Transmitted records had missing vital sign or symptom items in less than 2% of cases, spirometry data was always present. This evaluation showed than lung transplant recipients are willing and able to use a home-monitoring instrument, and that basic spirometry, data entry, and data transmission can be performed satisfactorily.

    Lung transplantation is the best treatment option in the final stages of diseases such as cystic fibrosis, pulmonary hypertension, chronic obstructive pulmonary disease, or idiopathic pulmonary fibrosis. Better surgical techniques and advances in immunosuppressor treatments have increased survival in lung transplant recipients, making longer follow-up necessary because complications can occur at any time after transplantation. For practical purposes, complications can be classified as early (those that normally occur within two months after transplantation), late (those that normally occur more than two months after transplantation), or time-independent (those that can occur at any time after transplantation). Many complications have nonspecific clinical and radiological manifestations, so the time factor is key to narrow the differential diagnosis. Imaging can guide interventional procedures and can detect complications early. This article aims to describe and illustrate the complications that can occur after lung transplantation from the clinical and radiological viewpoints so that they can be detected as early as possible.

    2016-03-01

    Infections with filamentous fungi are common in transplant recipients. The risk for aspergillosis and other invasive pulmonary mycosis (IPM) is high in patients undergoing stem cell and lung transplantations. The mortality rates range from 20% to 60% and depend on a number of risk factors. The typical manifestations of IPM are lung infiltrates, consolidations, and fungal tracheobronchitis. The most common infectious agent is Aspergillus fumigatus. Infections caused by non-Aspergillus molds are more frequent for various reasons. The species distribution of non-Aspergillus molds varies in different locations. Furthermore, infections caused by Mucor and Penicillium are increasing, as are infections caused by species resistant to azoles and amphotericin B. Most centers use antifungal prophylaxis with inhaled amphotericin B or oral azoles. Early diagnosis and therapy is crucial. Reliable information on the local microbiological spectrum is a prerequisite for the effective treatment of molds with primary or secondary resistance to antimycotic drugs.

    The objective of this study was to characterize the cortical activity pattern of one patient who received bilateral forearm transplants. Using fMRI we acquired motor and sensory brain activity every year after surgery and during three consecutive years while the patient underwent physical rehabilitation. The motor related cortical activity evaluated during the first year showed a sparse pattern involving several brain regions. Over time, the analysis showed a progressive delimitation of the motor-related areas that had significant activity. The results also showed continuous size reductions of the activated cluster in the motor cortex. The activation in the sensory cortex showed significant increases in cluster size over time. The intensity of both motor and sensory cortical activations correlated with the Disabilities of the Arm, Shoulder and Hand questionnaire. Our results show significant cortical reorganization of motor and sensory cortices after transplantation of bilateral forearm transplantation over a four-year period.

    We describe the key components of an outpatient pediatric recovery and rehabilitation program set up within the adult lung transplant service at the Alfred Hospital, Melbourne. Following discharge, pediatric lung transplant recipients and their families participated in an intensive 3-month outpatient rehabilitation program. Weekly sessions included education regarding transplant issues, physiotherapy, and occupational therapy sessions. The overall aim of the program was to comprehensively address physical rehabilitation and psychosocial and educational needs. Sessions tailored to meet the individual needs of the child were presented at an appropriate cognitive level. Education sessions for both the children and parents focused on medications, identification of infection and rejection, nutrition, physiotherapy/rehabilitation, occupational roles and stress management, donor issues, psychosocial readjustment, and transition issues. Physiotherapy included a progressive aerobic and strength training program, postural reeducation, and core stability. We incorporate Age-appropriate play activities: running, dancing, jumping, ball skills, and so on. Occupational therapy sessions addressed the primary roles of patient, students, and player. Transitions such as returning to school, friends, and the community were explored. Issues discussed included adjustment to new health status, strategies to manage side effects of medications, and altered body image issues. Weekly multidisciplinary team meetings were used to discuss and plan the rehabilitation progress. School liaison and visits occurred prior to school commencement with follow-up offered to review the ongoing transition process. Both patients and parents have reported a high level of satisfaction with the rehabilitation program. We plan to formally evaluate the program in the future.

    Elevated levels of serum prolactin (PRL) are common and well described in patients with chronic renal failure. We report the case of a 4-year-old girl who also presented with premature thelarche and transient galactorrhea. Neither peritoneal dialysis nor hemodialysis reduced her extremely elevated levels of PRL, which fluctuated from time to time, probably reflecting variations in lactotroph secretion rate. Bilateral nephrectomy (BN) was eventually followed by a progressive and significant rise in PRL levels, suggesting that even uremic kidneys can eliminate PRL through tubular breakdown. Kidney transplantation was responsible for a very abrupt normalization of PRL serum levels, much faster than that observed for creatinine. This confirms animal studies suggesting that elimination of PRL occurs both through glomerular filtration and tubular breakdown. We hypothesized that the seemingly precocious puberty may have resulted from a combination of growth hormone therapy, elevated PRL and a rise in estrogens through the aromatization of adrenal androgens. This case illustrates the impact of dialysis, BN and kidney transplantation on PRL, providing new knowledge on renal PRL metabolism. PMID:25984175

    Posttransplantation lymphoproliferative disorder (PTLD) is a rare complication of solid organ or allogenic bone marrow transplantation. Cases localized to the skin are even rarer, with only around 100 cases recorded in the literature [2]. We present a case of 60 year-old-woman, a lung transplant recipient, who presented with an asymptomatic violaceous nodule on her left medial calf. Histopathology was consistent with PTLD of the B-cell subtype, EBV negative. This case is unique in that it was of the B cell subtype of cutaneous PTLD, which has been less commonly observed than the T cell subtype. In addition, the case was EBV negative, which is rare in B cell cutaneous PTLD. The patient was treated with rituximab 600 mg IV weekly for four weeks and cytomegalovirus immune globulin (Cytogam) 100 mg/kg once, with resolution of the nodule. PMID:27617611

    Background Risk factors and outcomes of bronchial stricture following lung transplantation are not well defined. An association between acute rejection and development of stricture has been suggested in small case series. We evaluated this relationship using a large, national registry. Methods All lung transplants between 04/1994 and 12/2008 per the United Network for Organ Sharing database were analyzed. Generalized linear models were used to determine the association between early rejection and development of stricture after adjusting for potential confounders. The association of stricture with postoperative lung function and overall survival was also evaluated. Results 9,335 patients were included for analysis. The incidence of stricture was 11.5% (=1,077/9,335) with no significant change in incidence during the study period (p=0.13). Early rejection was associated with a significantly greater incidence of stricture [adjusted odds ratio (AOR) 1.40, 95% confidence interval (CI) 1.22 - 1.61; p<0.0001]. Male gender, restrictive lung disease, and pre-transplant requirement for hospitalization were also associated with stricture. Those who developed stricture had and a lower postoperative peak percent predicted forced expiratory volume at one second (median 74% vs. 86% for bilateral transplants only, p<0.0001), shorter unadjusted survival (median 6.09 vs. 6.82 years, p<0.001) and increased risk of death after adjusting for potential confounders (adjusted hazard ratio 1.13, CI 1.03 - 1.23, p=0.007). Conclusions Early rejection is associated with an increased incidence of stricture. Recipients with stricture demonstrate worse postoperative lung function and survival. Prospective studies may be warranted to further assess causality and the potential for coordinated rejection and stricture surveillance strategies to improve postoperative outcomes. PMID:23870829

    US pediatric transplant candidates have limited access to lung transplant due to the small number of donors within current geographic boundaries, leading to assertions that the current lung allocation system does not adequately serve pediatric patients. We hypothesized that broader geographic sharing of pediatric (adolescent, 12-17 years; child, <12 years) donor lungs would increase pediatric candidate access to transplant. We used the thoracic simulated allocation model to simulate broader geographic sharing. Simulation 1 used current allocation rules. Simulation 2 offered adolescent donor lungs across a wider geographic area to adolescents. Simulation 3 offered child donor lungs across a wider geographic area to adolescents. Simulation 4 combined simulations 2 and 3. Simulation 5 prioritized adolescent donor lungs to children across a wider geographic area. Simulation 4 resulted in 461 adolescent transplants per 100 patient-years on the waiting list (range 417-542), compared with 206 (range 180-228) under current rules. Simulation 5 resulted in 388 adolescent transplants per 100 patient-years on the waiting list (range 348-418) and likely increased transplant rates for children. Adult transplant rates, waitlist mortality, and 1-year posttransplant mortality were not adversely affected. Broader geographic sharing of pediatric donor lungs may increase pediatric candidate access to lung transplant. PMID:26523747

    We report the first successful bridge to lung transplantation using venovenous extracorporeal membrane oxygenation (ECMO) with an atrial septostomy for both pulmonary and right ventricular support. This strategy may provide an alternative to other forms of ECMO support as a bridge to lung transplantation, and potentially allow for ambulation and rehabilitation. PMID:26897198

    The purpose of this work was to develop an automated technique for calculating dynamic lung attenuation changes, through a forced expiratory maneuver, as a measure of split lung function. A total of ten patients post single lung transplantation (SLT) for emphysema were imaged using an Electron Beam CT Scanner; three were studied twice following stent placement. A single-slice flow study, using 100 msec exposures and 3 mm collimation, was performed at the level of the anastomosis during a forced expiration. Images were acquired every 500 msec for the first 3 seconds and every second for the last 4 seconds. An automated, knowledge-based system was developed to segment the chest wall, mediastinum, large airways and lung parenchyma in each image. Knowledge of the expected size, shape, topology and X-ray attenuation of anatomical structures were used to guide image segmentation involving attenuation thresholding, region-growing and morphology. From the segmented left and right parenchyma, the system calculated median attenuation (HU) and cross-sectional areas. These results were plotted against time for both the native and transplanted lungs. In five patients, significant shift of the attenuation/time curve to the right (slower flow) was detected, although the end expiration attenuation was not different. Following stent placement the curve shifted back to the left (faster flow).

    Despite improvement in median life expectancy and overall health, some children with cystic fibrosis (CF) progress to end-stage lung or liver disease and become candidates for transplant. Transplants for children with CF hold the promise to extend and improve the quality of life, but barriers to successful long-term outcomes include shortage of suitable donor organs; potential complications from the surgical procedure and immunosuppressants; risk of rejection and infection; and the need for lifelong, strict adherence to a complex medical regimen. This article reviews the indications and complications of lung and liver transplantation in children with CF. PMID:27469184

    BACKGROUND: Limited data are available regarding the etiologic impact of health care-associated pneumonia (HCAP) in lung transplant recipients. Therefore, our aim was to evaluate the microbiologic differences between HCAP and hospital-acquired pneumonia (HAP)/ventilator-associated pneumonia (VAP) in lung transplant recipients with a radiographically confirmed diagnosis of pneumonia. METHODS: We performed a retrospective cohort study of lung transplant recipients with pneumonia at one transplant center over a 7-year period. Eligible patients included lung transplant recipients who developed a first episode of radiographically confirmed pneumonia ≥ 48 h following transplantation. HCAP, HAP, and VAP were classified according to the American Thoracic Society/Infectious Diseases Society of America 2005 guidelines. χ2 and Student t tests were used to compare categorical and continuous variables, respectively. RESULTS: Sixty-eight lung transplant recipients developed at least one episode of pneumonia. HCAP (n = 42; 62%) was most common, followed by HAP/VAP (n = 26; 38%) stratified in HAP (n = 20; 77%) and VAP (n = 6; 23%). Pseudomonas aeruginosa was the predominantly isolated organism (n = 22; 32%), whereas invasive aspergillosis was uncommon (< 10%). Multiple-drug resistant (MDR) pathogens were less frequently isolated in patients with HCAP compared with HAP/VAP (5% vs 27%; P = .009). Opportunistic pathogens were less frequently identified in lung transplant recipients with HCAP than in those with HAP/VAP (7% vs 27%; P = .02). Lung transplant recipients with HCAP had a similar mortality at 90 days (n = 9 [21%] vs n = 4 [15%]; P = .3) compared with patients with HAP/VAP. CONCLUSIONS: HCAP was the most frequent infection in lung transplant recipients. MDR pathogens and opportunistic pathogens were more frequently isolated in HAP/VAP. There were no differences in 30- and 90-day mortality between lung transplant recipients with HCAP and those with HAP/VAP. PMID:25742187

    Lung transplantation can be a life-saving measure for people with end-stage lung disease from systemic sclerosis. However, outcomes of lung transplantation may be compromised by gastrointestinal manifestations of systemic sclerosis, which can involve any part of the gastrointestinal tract. Esophageal and gastric disease can be managed by enteral feeding with the use of a gastrojejunal feeding tube. In this report, we describe the clinical courses of 2 lung transplant recipients with systemic sclerosis who experienced severe and prolonged barium-impaction ileus after insertion of a percutaneous gastrojejunal feeding tube.

    Survival in patients with cystic fibrosis (CF) has improved dramatically over the past 30 to 40 years, with mean survival now approximately 40 years. Nonetheless, progressive respiratory insufficiency remains the major cause of mortality in CF patients, and lung transplantation (LT) is eventually required. Timing of listing for LT is critical, because up to 25 to 41% of CF patients have died while awaiting LT. Globally, approximately 16.4% of lung transplants are performed in adults with CF. Survival rates for LT recipients with CF are superior to other indications, yet LT is associated with substantial morbidity and mortality (~50% at 5-year survival rates). Myriad complications of LT include allograft failure (acute or chronic), opportunistic infections, and complications of chronic immunosuppressive medications (including malignancy). Determining which patients are candidates for LT is difficult, and survival benefit remains uncertain. In this review, we discuss when LT should be considered, criteria for identifying candidates, contraindications to LT, results post-LT, and specific complications that may be associated with LT. Infectious complications that may complicate CF (particularly Burkholderia cepacia spp., opportunistic fungi, and nontuberculous mycobacteria) are discussed. PMID:25826595

    Background Due to the complex therapy and the required high level of immunosuppression, lung recipients are at high risk to develop many different long term complications. Methods From 1993–2000, a total of 54 lung transplantation (LuTx) were performed at our center. Complications, graft and patient survival of this cohort was retrospectively analyzed. Results One/five and ten-year patient survival was 71.4%, 41.2% and 25.4%; at last follow up (4/2010), twelve patients were alive. Of the 39 deceased patients, 26 died from infectious complications. Other causes of death were myocardial infarction (n=1), progressive graft failure (n=1), intracerebral bleeding (n=2), basilary vein thrombosis (n=1), pulmonary emboli (n=1), others (n=7). Surgical complication rate was 27.7% during the first year and 25% for the 12 long term survivors. Perioperative rejection rate was 35%, and 91.6% for the 12 patients currently alive. Infection incidence during first hospitalization was 79.6% (1.3 episodes per transplant) and 100% for long term survivors. Commonly isolated pathogens were cytomegalovirus (56.8%), Aspergillus (29.4%), RSV (13.7%). Other common complications were renal failure (56.8%), osteoporosis (54.9%), hypertension (45%), diabetes mellitus (19.6%). Conclusions Infection and rejection remain the most common complications following LuTx with many other events to be considered. PMID:27293842

    Pulmonary complications due to infection and idiopathic pneumonia syndrome (IPS), a noninfectious lung injury in hematopoietic stem cell transplant (HSCT) recipients, are frequent causes of transplantation-related mortality and morbidity. Our objective was to characterize the global bronchoalveolar lavage fluid (BALF) protein expression of IPS to identify proteins and pathways that differentiate IPS from infectious lung injury after HSCT. We studied 30 BALF samples from patients who developed lung injury within 180 days of HSCT or cellular therapy transfusion (natural killer cell transfusion). Adult subjects were classified as having IPS or infectious lung injury by the criteria outlined in the 2011 American Thoracic Society statement. BALF was depleted of hemoglobin and 14 high-abundance proteins, treated with trypsin, and labeled with isobaric tagging for relative and absolute quantification (iTRAQ) 8-plex reagent for two-dimensional capillary liquid chromatography (LC) and data dependent peptide tandem mass spectrometry (MS) on an Orbitrap Velos system in higher-energy collision-induced dissociation activation mode. Protein identification employed a target-decoy strategy using ProteinPilot within Galaxy P. The relative protein abundance was determined with reference to a global internal standard consisting of pooled BALF from patients with respiratory failure and no history of HSCT. A variance weighted t-test controlling for a false discovery rate of ≤5% was used to identify proteins that showed differential expression between IPS and infectious lung injury. The biological relevance of these proteins was determined by using gene ontology enrichment analysis and Ingenuity Pathway Analysis. We characterized 12 IPS and 18 infectious lung injury BALF samples. In the 5 iTRAQ LC-MS/MS experiments 845, 735, 532, 615, and 594 proteins were identified for a total of 1125 unique proteins and 368 common proteins across all 5 LC-MS/MS experiments.

    Objectives: Immunosuppressive pharmacologic agents prescribed to patients with diffuse interstitial and inflammatory lung disease and lung transplant recipients are associated with potential risks for adverse reactions. Strategies for minimizing such risks include administering these drugs according to established, safe protocols; monitoring to detect manifestations of toxicity; and patient education. Hence, an evidence-based guideline for physicians can improve safety and optimize the likelihood of a successful outcome. To maximize the likelihood that these agents will be used safely, the American College of Chest Physicians established a committee to examine the clinical evidence for the administration and monitoring of immunosuppressive drugs (with the exception of corticosteroids) to identify associated toxicities associated with each drug and appropriate protocols for monitoring these agents. Methods: Committee members developed and refined a series of questions about toxicities of immunosuppressives and current approaches to administration and monitoring. A systematic review was carried out by the American College of Chest Physicians. Committee members were supplied with this information and created this evidence-based guideline. Conclusions: It is hoped that these guidelines will improve patient safety when immunosuppressive drugs are given to lung transplant recipients and to patients with diffuse interstitial lung disease.

  1. Pretransplant dyslipidaemia determines outcome in lung transplant recipients

    2013-01-01

    Background There is little knowledge about the effect of dyslipidaemia on the outcome after lung transplantation. Thus, the aim of this retrospective single centre study was to analyse the impact of the plasma lipid profile on mortality in lung transplant recipients. From January 2000 to December 2008 the charts of 172 consecutive lung transplantation recipients were analysed. At baseline and after one year lipid profiles were routinely collected. During the follow-up major cardiovascular events (MCE; beginning of dialysis, cerebrovascular insult or myocardial infarction) were recorded. The follow-up period ended December 2010. Findings Over all total cholesterol (4.3 ± 1.6 vs. 5.4 ± 1.3 mmol/l, p < 0.0001), triglycerides (1.2 ± 0.7 vs. 2.4 ± 1.3 mmol/l, p < 0.0001), HDL (1.5 ± 0.6 vs. 1.7 ± 0.6 mmol/l, p = 0.003) and TC/HDL ratio (3.0 ± 1.0 vs. 3.6 ± 1.2, p = 0.002) increased significantly after 1 year. During the observational period 6.9% (10 patients) suffered a major cardiac event. In univariate analysis MCE was associated with baseline TC: on average the event-group had a 33% higher baseline TC (5.6 vs. 4.2 mmol/l, OR 1.6, CI 1.1 – 2.2, p = 0.02). The total mortality in the observational period was 25% (36 patients overall). In univariate analysis mortality was associated with increased TC/HDL ratio. The non-survivors had on average a 22% higher baseline TC/HDL ratio (3.6 vs. 2.8, HR 2.8, CI 1.2 – 3.5, p = 0.001). There was no association between mortality and TC (p = 0.33), triglycerides (p = 0.34), HDL (p = 0.78) and creatinine (p = 0.73). In a multivariate model the hazard ratio was 1.5 (1.2 – 1.9, p = 0.001) per increase of 0.4 TC/HDL ratio. Conclusions This study shows that the total cholesterol before transplantation is associated with the incidence of MCE and the cholesterol/HDL ratio with mortality in lung transplanted recipients.

    Lung transplantation presents a wide range of challenges for multidisciplinary teams that manage the care of the recipients. Transplant teams should perform a thorough evaluation of transplant candidates, in order to ensure the best possible post-transplant outcomes. That is especially true for the psychologist, because psychological issues can arise at any point during the perioperative period. The objective of our study was to evaluate the psychological causes of contraindication to waiting list inclusion in a referral program for lung transplantation. We retrospectively analyzed data on psychological issues presented by lung transplant candidates, in order to understand these matters in our population and to reflect upon ways to improve the selection process.

    Hyperimmunized patients have restricted access to lung transplantation because of the low rate of donor lung availability. Sensitization to human leukocyte antigen is associated with acute rejection, allograft dysfunction, and decreased survival. Prospective crossmatching could allow matching a lung graft with the recipient; however, such a strategy would increase graft ischemia, with a worse impact on the long-term results of lung transplantation. We used logistic ex vivo lung perfusion for 3 patients at the Foch Hospital while waiting for a negative result of the prospective crossmatching and then moved forward to lung transplantation. All patients are alive 3 years after bilateral lung transplantation.

    Background Lung transplantation provides a viable option for survival of end-stage respiratory disease. In addition to prolonging survival, there is considerable interest in improving patient-related outcomes such as transplant recipients’ symptom experiences. Methods A prospective, repeated measures design was used to describe the symptom experience of 85 lung transplant recipients between 2000–2005. The Transplant Symptom Inventory (TSI) was administered before and at 1, 3, 6, 9, and 12 months post-transplant. Ridit analysis provided a unique method for describing symptom experiences and changes. Results After lung transplantation, significant (p<.05) improvements were reported for the most frequently occurring and most distressing pre-transplant symptoms (e.g., shortness of breath with activity). Marked increases in the frequency and distress of new symptoms, such as tremors were also reported. Patterns of symptom frequency and distress varied with the time since transplant. Conclusion The findings provide data-based information that can be used to inform pre- and post-transplant patient education and also help caregivers anticipate a general time frame for symptom changes in order to prevent or minimize symptoms and their associated distress. In addition, symptoms are described, using an innovative method of illustration which shows “at-a-glance” changes or lack of changes in patients’ symptoms from pre- to post-lung transplant.

    Aspergilloma or mycetoma is a saprophytic fungal infection that colonizes pre-existing excavated lung lesion. However, its association with systemic sclerosis related interstitial lung disease is unusual and scarcely found in literature. We report a middle aged female with long standing systemic sclerosis, who was on immunosuppressive therapy for many years, presented with repeated haemoptysis. Although provisionally pulmonary tuberculosis was suspected, imaging investigations showed presence of bilateral masses inside bullous air spaces along with air-crescent sign suggestive of fungal ball. Subsequent Computed tomography guided needle aspiration from lung mass confirmed Aspergillus fumigatus as aetiologic agent on fungal culture. Patient was treated conservatively for haemoptysis and with oral antifungal drug as surgical removal of fungal ball was not an option due to poor pulmonary reserve. Although she had been treated with itraconazole for more than three years, she had recurrent haemoptysis during this period without any significant regression of size of the aspergilloma. Management of aspergilloma in a background of extensive interstitial lung disease remains poorly defined and complicated. Thereby, overall prognosis is unfavourable and depends on evolution of both underlying scleroderma as well as aspergilloma. PMID:26816937

    Ventilation and perfusion scans were obtained in six subjects who had undergone heart-lung transplantation with consequent denervation of the cardiopulmonary axis. Two of the subjects had developed obliterative bronchiolitis, which is believed to be a form of chronic rejection. Their pulmonary function tests demonstrated airflow obstruction and their scintigraphic studies were abnormal. In the remaining four subjects without obstructive airways disease, ventilation and planar perfusion scans were normal. Single photon emission computed tomography imaging of pulmonary perfusion in these patients revealed a layered distribution of blood flow indistinguishable from that of normal individuals. It is concluded that neurogenic mechanisms have little influence on the pattern of local pulmonary blood flow at rest.

    We report five cases of possible drug-induced periostitis associated with long-term use of voriconazole therapy after lung transplantation (LT). The diagnosis of periostitis was made by the documentation of bone pain, elevation of serum alkaline phosphatase and characteristic findings on radionuclide bone imaging in the absence of any identifiable rheumatologic disease. This periostitis appears similar to hypertrophic osteoarthopathy (HOA) but does not meet all criteria for HOA. In all patients, the symptoms resolved rapidly after discontinuation of voriconazole therapy. Awareness of this potential syndrome, which manifests as bone pain, elevated serum alkaline phosphatase and a bone scan suggestive of periostitis, is necessary in LT recipients on long-term voriconazole.

    Mycobacterium abscessus complex is an emerging pathogen in lung transplant candidates and recipients. M. abscessus complex is widespread in the environment and can cause pulmonary, skin and soft tissue, and disseminated infection, particularly in lung transplant recipients. It is innately resistant to many antibiotics making it difficult to treat. Herein we describe the epidemiology, clinical manifestations, diagnosis and treatment of M. abscessus with an emphasis on lung transplant candidates and recipients. We also outline the areas where data are lacking and the areas where further research is urgently needed. PMID:26732819

    Advanced lung disease (ALD) that requires lung transplantation (LTX) is frequently associated with pulmonary hypertension (PH). Whether the presence of PH significantly affects the outcomes following single-lung transplantation (SLT) remains controversial. Therefore, we retrospectively examined the outcomes of 279 consecutive SLT recipients transplanted at our centre, and the patients were split into four groups based on their mean pulmonary artery pressure values. Outcomes, including long-term survival and primary graft dysfunction, did not differ significantly for patients with versus without PH, even when PH was severe. We suggest that SLT can be performed safely in patients with ALD-associated PH. PMID:26621135

    The long-term survival of first successful renal transplants, along with overall patient survival, was studied retrospectively in 309 recipients at Belfast City Hospital between 1968 and 1986, of whom 155 had undergone prior bilateral nephrectomy (BN) and 154 had not (non-BN). The groups were comparable as regards mean age, gender, primary diagnoses, clinical status, pre-existing hypertension and pre-transplant dialysis and transfusion. There were 34 organs (BN 14, non-BN 20) from living related donors. Donor ages were comparable, as were histocompatibility findings. Recipients more than 60, with diabetic nephropathy, or with other co-morbidity were excluded. All recipients took azathioprine and low-dose steroid as maintenance antirejection, fewer than 3% switching to cyclosporine or other drugs during first graft survival. Mean BN graft survival was 15.9 years (95% CI 14.1-17.7) compared to 12.9 for non-BN (95% CI 11.3-14.5; p < 0.01). Mean BN patient survival was 19.4 years (95% CI 17.6-21.2) and non-BN was 14.9 years (95% CI 13.2-16.6; p < 0.01). Cumulative BN graft survival was 76.8% at 5 years, 61.6% at 10 years, and 37.4% at 20 years, compared to 67.1%, 53.5% and 27.0% for non-BN (p < 0.01). Overall BN patient survival was 84.5% at 5 years, 74.2% at 10 years and 51.6% at 20 years, with non-BN equivalents of 72.3%, 49.0% and 24.5%, respectively (p < 0.01). Long-term BN survivors also had less hypertension than non-BN (22.8% v 54.8% at 20 years; p < 0.05) which may be relevant to their better survival. Overall (BN plus non-BN) median graft (14.4 years) and patient (17.6 years) survival are testimony to the continuing long-term success of the low-dose steroid regime followed in Belfast from 1968 to 1986.

    The lungs are dually perfused by the pulmonary artery and the bronchial arteries. This study aimed to test the feasibility of dual-perfusion techniques with the bronchial artery circulation and pulmonary artery circulation synchronously perfused using ex vivo lung perfusion (EVLP) and evaluate the effects of dual-perfusion on posttransplant lung graft function. Using rat heart-lung blocks, we developed a dual-perfusion EVLP circuit (dual-EVLP), and compared cellular metabolism, expression of inflammatory mediators, and posttransplant graft function in lung allografts maintained with dual-EVLP, standard-EVLP, or cold static preservation. The microvasculature in lung grafts after transplant was objectively evaluated using microcomputed tomography angiography. Lung grafts subjected to dual-EVLP exhibited significantly better lung graft function with reduced proinflammatory profiles and more mitochondrial biogenesis, leading to better posttransplant function and compliance, as compared with standard-EVLP or static cold preservation. Interestingly, lung grafts maintained on dual-EVLP exhibited remarkably increased microvasculature and perfusion as compared with lungs maintained on standard-EVLP. Our results suggest that lung grafts can be perfused and preserved using dual-perfusion EVLP techniques that contribute to better graft function by reducing proinflammatory profiles and activating mitochondrial respiration. Dual-EVLP also yields better posttransplant graft function through increased microvasculature and better perfusion of the lung grafts after transplantation.

    Lung transplantation is a drastic life event that usually takes place in the preterminal phase of a lung disease. Although a lung transplantation increases the quality of life considerably, patients still face a range of physical and psychosocial strains. This article presents experiences made with a "Life Management Group" for lung transplantation patients. The aim of the eight group meetings was to encourage the sharing of experiences between patients and to support them in their active and competent realizations of desires and plans. Physical health, self-identity of lung transplant recipients, growing problems financing medical treatment and the forming of doctor-patient-relationships were the important issues. Patients were able to reach a higher level of self efficiency; they could use active coping strategies and develop their social networks. Positive experiences were made with the implementation of group therapy for lung transplantation patients. Lung transplant recipients have to deal with specific problems of identity. On the other hand, there are growing health-economic questions also from the patient's point of view. PMID:16586305

    INTRODUCTION: Total hip replacement is generally proposed for renal transplant patients with avascular osteonecrosis of the femoral head. PURPOSE: The purpose of the study is to report the long-term outcome after rehabilitation of bilateral total hip arthroplasty in a patient with renal transplantation suffering from avascular osteonecrosis of the both femoral heads. MATERIAL AND METHOD: The patient S.D, 49 years old at follow-up. Few months after renal transplantation, the patient had got avascular osteonecrosis of both femoral head. One year after transplantation the total hip arthroplasty for both hip joints were performed. Three years later repeat total hip arthroplasty surgery for left hip was performed. After any surgery intervention the patient was referred for inpatient rehabilitation. For clinical assessment the clinical findings and Harris Hip Score have been used. The rehabilitation program consisted of exercises, occupational therapy, and patient education. RESULTS: After any rehabilitation treatment the patient had improvement of clinical findings. At follow-up assessment outcome for both hip function was good - Harris Hip Score was 81 points. CONCLUSION: Rehabilitation is integral part of multidisciplinary treatment of renal transplant recipient after total hip arthroplasty. Regular exercise training of these patients is very important for improving of their long-term outcome. PMID:27275350

    Recently, the numbers of lung transplantation (LT) has been increased in Korea. However, post-LT outcome has not been successful in all patients, which may be partially affected by the primary lung disease. Therefore comprehensive understanding in original pathological diagnosis of patients with LT would be needed for achieving better clinical outcome. To address this issue, we performed clinico-pathological analysis of the explanted lungs from 29 patients who underwent LT over a 9-yr period in Seoul National University Hospital. Among them, 26 patients received single (1/26) or double (25/26) LT, while heart-lung transplantation was performed in 3 patients. The final clinico-pathological diagnoses were idiopathic pulmonary fibrosis/usual interstitial pneumonia (UIP) (n = 6), acute interstitial pneumonia (AIP)/diffuse alveolar damage (DAD) (n = 4), AIP/non-specific interstitial pneumonia with DAD (n = 1), collagen vascular disease-related interstitial lung disease (CVD-ILD)/DAD (n = 3), CVD-ILD/UIP (n = 1), lymphangioleiomyomatosis (n = 1), bronchiectasis (n = 4), pulmonary arterial hypertension (n = 2), tuberculosis (n = 1), bronchiolitis obliterans (BO) (n = 1), and lung cancer (n = 1). Moreover, 4 patients who had chemotherapy and hematopoietic stem cell transplantation due to hematologic malignancy showed unclassifiable interstitial pneumonia with extensive fibrosis in the lungs. Our study demonstrates that pathology of the explanted lungs from Korean patients with LT is different from that of other countries except for interstitial lung disease and bronchiectasis, which may be helpful for optimization of selecting LT candidates for Korean patients.

    Viral gastroenteritis causing diarrhea is a common complication observed in lung transplant recipients. Differently from the mild and typically self-limited disease seen in immunocompetent subjects, immunocompromised patients frequently have a more severe course. Norovirus and rotavirus are among the leading causes of severe gastroenteritis in transplant recipients. Specific treatment is unavailable, although good supportive treatment can significantly reduce morbidity. Previous studies have suggested that oral immunoglobulins may be used for the treatment of acute viral gastroenteritis after solid-organ transplantation. Herein, we conducted a retrospective chart review of 12 lung transplant recipients with norovirus-induced gastroenteritis who were treated with oral immunoglobulins for 2 days. Eleven patients were successfully treated, whereas 1 subject was only mildly improved. Four patients had at least 1 recurrence. No significant adverse effects were observed. We conclude that oral immunoglobulins may be clinically useful for lung transplant recipients with norovirus-induced gastroenteritis.

    Lung transplantation is a method useful in such non-malignant end-stage parenchymal and vascular diseases as: chronic obstructive pulmonary disease (COPD), idiopathic interstitial pulmonary fibrosis, cystic fibrosis, or primary pulmonary hypertension. The main aim of this procedure is to extend the patient's lifespan and quality of life. However, the availability of the operation is limited by organ access. In this paper we present the case of a 58-year-old female in the fourth stage of COPD, who was classified to have a single lung transplantation. Because of some technical problems it was decided to transplant a left donor lung in the right recipient lung locus. Positive cross match was demonstrated retrospectively, and we applied five courses of plasmapheresis. Human immunoglobulin and rituximab treatment were performed to decrease the impact of lymphocytotoxic antibodies. The patient survived 498 days after transplantation, 271 in the hospital.

    Chronic lung allograft dysfunction (CLAD) is the major factor limiting long-term success of lung transplantation. Polymorphisms of surfactant protein D (SP-D), an important molecule within lung innate immunity, have been associated with various lung diseases. We investigated the association between donor lung SP-D polymorphisms and posttransplant CLAD and survival in 191 lung transplant recipients consecutively transplanted. Recipients were prospectively followed with routine pulmonary function tests. Donor DNA was assayed by pyrosequencing for SP-D polymorphisms of two single-nucleotide variations altering amino acids in the mature protein N-terminal domain codon 11 (Met(11) Thr), and in codon 160 (Ala(160) Thr) of the C-terminal domain. CLAD was diagnosed in 88/191 patients, and 60/191 patients have died. Recipients of allografts that expressed the homozygous Met(11) Met variant of aa11 had significantly greater freedom from CLAD development and better survival compared to those with the homozygous Thr(11) Th variant of aa11. No significant association was noted for SP-D variants of aa160. Lung allografts with the SP-D polymorphic variant Thr(11) Th of aa11 are associated with development of CLAD and reduced survival. The observed genetic differences of the donor lung, potentially with their effects on innate immunity, may influence the clinical outcomes after lung transplantation.

    Lymphoproliferative syndromes are the most common tumors in transplant recipients. More than 90% of posttransplantation lymphoproliferative syndromes (PTLS) are considered to be associated with Epstein-Barr virus, and 86% are of the B-cell line. Histopathology ranges from polymorphic-reactive to monomorphic forms. Clonality should be studied using molecular biology techniques. Clinically, a differentiation is usually made between early PTLS (occurring within 1 year after transplantation) and late PTLS, which occur as localized or disseminated nodal lymphomas. In localized forms, immunosuppression should be discontinued or decreased, and the involved area should be subsequently resected or irradiated. In disseminated cases, immunosuppression should be decreased and administration of acyclovir/ganciclovir should be considered. If this is not effective, treatment should be started with anti-CD20 monoclonal antibodies (rituximab). If no response occurs, use of chemotherapy, possibly with interferon, should be considered. Our aim was to report the incidence, clinical signs, and treatment in a series of patients undergoing lung transplantation (LTx).

  2. Postinfectious bronchiolitis obliterans in children: lessons from bronchiolitis obliterans after lung transplantation and hematopoietic stem cell transplantation

    PubMed Central

    2015-01-01

    Postinfectious bronchiolitis obliterans (PIBO) is an irreversible obstructive lung disease characterized by subepithelial inflammation and fibrotic narrowing of the bronchioles after lower respiratory tract infection during childhood, especially early childhood. Although diagnosis of PIBO should be confirmed by histopathology, it is generally based on history and clinical findings. Irreversible airway obstruction is demonstrated by decreased forced expiratory volume in 1 second with an absent bronchodilator response, and by mosaic perfusion, air trapping, and/or bronchiectasis on computed tomography images. However, lung function tests using spirometry are not feasible in young children, and most cases of PIBO develop during early childhood. Further studies focused on obtaining serial measurements of lung function in infants and toddlers with a risk of bronchiolitis obliterans (BO) after lower respiratory tract infection are therefore needed. Although an optimal treatment for PIBO has not been established, corticosteroids have been used to target the inflammatory component. Other treatment modalities for BO after lung transplantation or hematopoietic stem cell transplantation have been studied in clinical trials, and the results can be extrapolated for the treatment of PIBO. Lung transplantation remains the final option for children with PIBO who have progressed to end-stage lung disease. PMID:26770220

    A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was 'Can lungs be taken for transplantation from donors with a significant smoking history?’. Five papers were found using the reported search that represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. These studies compared the outcome and survival between patients who receive lungs from smokers with those receiving non-smoker lungs. None of these studies were randomized controlled trials. They retrospectively analysed a cohort of patients undergoing lung transplantation for the past 10 years. These studies showed worse outcomes in the early postoperative period, such as longer intensive care unit stay, longer ventilation time and higher early postoperative mortality, with lungs harvested from smokers. Two studies also demonstrated a worse long-term outcome in recipients of lungs from smokers, whereas the other two showed worse results during the early postoperative period only. These latter two studies reported similar survival rates after 3 months and up to 3 years in recipients receiving smoker vs non-smoker lungs. One study, however, showed a better 5-year survival with smoker lungs compared with non-smokers, although in this study, lungs from heavy smokers showed the worse outcome. Despite the difference in long-term results and outcome reported by these authors, all of these studies unanimously indicate that lungs from smokers should not be rejected, as survival in these patients receiving smoker lungs is still significantly higher in 3 and 5 years compared with that in those who remain on the transplant waiting list. In conclusion, the current evidence in the literature suggests that lungs from smokers can be used for transplantation. Patients should, however, be fully informed of

    In conjunction with the rising number of lung transplant operations in the past decade, an increased predisposition to venous thrombosis (VT), particularly within the first year posttransplantation has been observed. Previous studies have revealed that between 8.6% and 12% of patients develop VT, which can ultimately result in pulmonary emboli (PE).Transplanted lungs pose a much greater infarction risk due to their lack of collateral vascularisation, relying entirely on the vasa publica--the pulmonary artery--in the absence of vasa privata. Such losses in viable lung parenchyma are always serious, but carry still greater risks for single-lung transplant recipients, an early diagnosis and treatment remain critical. Here we report on two cases of PE after lung transplantation, both of whom were managed with catheter fragmentation and local thrombolysis. In our opinion, this approach represents a viable treatment for symptomatic PE in lung transplant recipients. The benefits and risks of the alternative treatment options in these special cases will be reviewed and the definitive therapy was described. In the patients treated, catheter fragmentation with localized thrombolysis resulted in short term improvements in graft function, but could not prevent later lung infarction in one case.

    The number of organ donors is limited by many contraindications for donation and poor quality of potential organ donors. Abdominal infection is a generally accepted contraindication for donation of abdominal organs. We present a 43-year-old man with lethal brain injury, blunt abdominal trauma, and intestinal perforation. After withdrawal of life-sustaining treatment and circulatory arrest, a minilaparotomy confirmed abdominal contamination with intestinal content. After closure of the abdomen, organs were preserved with in situ preservation with an aortic cannula inserted via the femoral artery. Thereafter, the kidneys were procured via bilateral lumbotomy to reduce the risk of direct bacterial contamination; lungs were retrieved following a standard practice. There was no bacterial or fungal growth in the machine preservation fluid of both kidneys. All organs were successfully transplanted, without postoperative infection, and functioned well after 6 months. We hereby show that direct contamination of organs can be avoided with the use of in situ preservation and retroperitoneal procurement. Intestinal perforation is not an absolute contraindication for donation, although the risk of bacterial or fungal transmission has to be evaluated per case. PMID:27500248

    The osteoplastic tracheobronchopathy affects the trachea, main, lobar and smaller bronchi, causing their stenosis. Nowadays the mainstay of the treatment of such patients is the cryodestruction, laser destruction and the endoscopic buginage of the trachea and bronchi. The palliative nature and low efficacy of these procedures forces to search new ways of treatment. The traditional lung transplantation or separate trachea and lung transplantation is inappropriate because of the complex affection of both trachea and bronchi. The experimental study aimed the possibility of thyreotracheolung revascularized donor complex transplantation.

    Treatment of injured donor lungs ex vivo to accelerate organ recovery and ameliorate reperfusion injury could have a major impact in lung transplantation. We have recently demonstrated a feasible technique for prolonged (12 h) normothermic ex vivo lung perfusion (EVLP). This study was performed to examine the impact of prolonged EVLP on ischemic injury. Pig donor lungs were cold preserved in Perfadex for 12 h and subsequently divided into two groups: cold static preservation (CSP) or EVLP at 37 degrees C with Steen solution for a further 12 h (total 24 h preservation). Lungs were then transplanted and reperfused for 4 h. EVLP preservation resulted in significantly better lung oxygenation (PaO(2) 531 +/- 43 vs. 244 +/- 49 mmHg, p < 0.01) and lower edema formation rates after transplantation. Alveolar epithelial cell tight junction integrity, evaluated by zona occludens-1 protein staining, was disrupted in the cell membranes after prolonged CSP but not after EVLP. The maintenance of integrity of barrier function during EVLP translates into significant attenuation of reperfusion injury and improved graft performance after transplantation. Integrity of functional metabolic pathways during normothermic perfusion was confirmed by effective gene transfer and GFP protein synthesis by lung alveolar cells. In conclusion, EVLP prevents ongoing injury associated with prolonged ischemia and accelerates lung recovery. PMID:19663886

    Background As endothelial progenitor cells (EPCs) attenuated acute lung injury (ALI) in rabbit model, we hypothesized that autologous EPCs preserved lung graft function during the acute reperfusion period of lung transplantation and tested the therapeutic potential of EPCs in a porcine model of lung transplantation with prolonged graft ischemia. Methods Day-7 EPCs isolated from the recipient subjects or plain culture media were administered into the left pulmonary artery immediately before restoration of pulmonary blood flow in a porcine lung allotransplantation model, with the transplantation surgeons blinded to the content of injection. Hemodynamics and arterial blood gas were recorded, and the right pulmonary artery was occluded 30 min after reperfusion to evaluate the lung graft function. The lung grafts were sectioned for histological examination at the end of experiments. The total ischemic time for lung graft was approximately 14 h. Results All animals receiving plain medium died within 40 min after reperfusion, but 3 out of 5 (60%) piglets receiving EPCs survived up to 4 h after diversion of the entire cardiac output into the lung graft (P<0.01). The donor body weight, recipient body weight, cold ischemic time, and time for anastomosis were comparable between the EPC and control group (P=0.989, 0.822, 0.843, and 0.452, respectively). The mean aortic pressure decreased, and the cardiac output and mean pulmonary artery pressure elevated after right pulmonary artery occlusion. All these parameters were gradually compensated in the EPC group but decompensated in the control group. Better preservation of gas exchange function, reduced thrombi formation in the terminal pulmonary arterioles, and attenuated interstitial hemorrhage of the lung graft were observed in the EPC group. Conclusions We concluded autologous EPCs significantly enhanced the function of lung allograft and improved survival in a porcine model of lung transplantation with prolonged ischemia

    Abstract Objective: To evaluate the changes in lung function in the first year after single lung transplantation in patients with idiopathic pulmonary fibrosis (IPF). Methods: We retrospectively evaluated patients with IPF who underwent single lung transplantation between January of 2006 and December of 2012, reviewing the changes in the lung function occurring during the first year after the procedure. Results: Of the 218 patients undergoing lung transplantation during the study period, 79 (36.2%) had IPF. Of those 79 patients, 24 (30%) died, and 11 (14%) did not undergo spirometry at the end of the first year. Of the 44 patients included in the study, 29 (66%) were men. The mean age of the patients was 57 years. Before transplantation, mean FVC, FEV1, and FEV1/FVC ratio were 1.78 L (50% of predicted), 1.48 L (52% of predicted), and 83%, respectively. In the first month after transplantation, there was a mean increase of 12% in FVC (400 mL) and FEV1 (350 mL). In the third month after transplantation, there were additional increases, of 5% (170 mL) in FVC and 1% (50 mL) in FEV1. At the end of the first year, the functional improvement persisted, with a mean gain of 19% (620 mL) in FVC and 16% (430 mL) in FEV1. Conclusions: Single lung transplantation in IPF patients who survive for at least one year provides significant and progressive benefits in lung function during the first year. This procedure is an important therapeutic alternative in the management of IPF. PMID:26398749

    Background Patients with short telomere syndromes and pulmonary fibrosis have increased complications after lung transplant. However, the more general impact of donor and recipient telomere length in lung transplant has not been well characterized. Methods This was an observational cohort study of patients who received lung transplant at a single center between January 1st 2012 and January 31st 2015. Relative donor lymphocyte telomere length was measured and classified into long (third tertile) and short (other tertiles). Relative recipient lung telomere length was measured and classified into short (first tertile) and long (other tertiles). Outcome data included survival, need for modification of immunosuppression, liver or kidney injury, cytomegalovirus reactivation, and acute rejection. Results Recipient lung tissue telomere lengths were measured for 54 of the 79 patients (68.3%) who underwent transplant during the study period. Donor lymphocyte telomeres were measured for 45 (83.3%) of these recipients. Neither long donor telomere length (hazard ratio [HR] = 0.58, 95% confidence interval [CI], 0.12–2.85, p = 0.50) nor short recipient telomere length (HR = 1.01, 95% CI = 0.50–2.05, p = 0.96) were associated with adjusted survival following lung transplant. Recipients with short telomeres were less likely to have acute cellular rejection (23.5% vs. 58.8%, p = 0.02) but were not more likely to have other organ dysfunction. Conclusions In this small cohort, neither long donor lymphocyte telomeres nor short recipient lung tissue telomeres were associated with adjusted survival after lung transplantation. Larger studies are needed to confirm these findings. PMID:27589328

    As a result of clinical heart-lung transplantation, the lungs are denervated below the level of the tracheal anastomosis. It has been questioned whether afferent vagal reinnervation occurs after surgery. Here we report the cough frequency, during inhalation of ultrasonically nebulized distilled water, of 15 heart-lung transplant patients studied 6 wk to 36 months after surgery. They were compared with 15 normal subjects of a similar age and sex. The distribution of the aerosol was studied in five normal subjects using /sup 99m/technetium diethylene triamine pentaacetate (/sup 99m/Tc-DTPA) in saline. In seven patients, the sensitivity of the laryngeal mucosa to instilled distilled water (0.2 ml) was tested at the time of fiberoptic bronchoscopy by recording the cough response. Ten percent of the aerosol was deposited onto the larynx and trachea, 56% on the central airways, and 34% in the periphery of the lung. The cough response to the aerosol was strikingly diminished in the patients compared with normal subjects (p less than 0.001), but all seven patients coughed when distilled water was instilled onto the larynx. As expected, the laryngeal mucosa of heart-lung transplant patients remains sensitive to distilled water. However, the diminished coughing when the distilled water is distributed by aerosol to the central airways supports the view that vagal afferent nerves do not reinnervate the lungs after heart-lung transplantation, up to 36 months after surgery.

    Lung transplantation is an effective therapy for many patients with end-stage lung disease. Few centers across the United States offer this therapy, as a successful lung transplant program requires significant institutional resources and specialized personnel. Analysis of the United Network of Organ Sharing database reveals that the failure rate of new programs exceeds 40%. These data suggest that an accurate assessment of program viability as well as a strategy to continuously assess defined quality measures is needed. As part of strategic planning, regional availability of recipient and donors should be assessed. Additionally, analysis of institutional expertise at the physician, support staff, financial, and administrative levels is necessary. In May of 2007, we started a new lung transplant program at the University of Iowa Hospitals and Clinics and have performed 101 transplants with an average recipient 1-year survival of 91%, placing our program among the top in the country for the past 5 years. Herein, we review internal and external factors that impact the viability of a new lung transplant program. We discuss the use of four prospectively identified quality measures: volume, recipient outcomes, financial solvency, and academic contribution as one approach to achieve programmatic excellence.

    Many candidates for lung transplantation (LT) die on the waiting list, raising the question of graft availability and strategy for organ allocation. We report the experience of the new organ allocation program, "High Emergency Lung Transplantation" (HELT), since its implementation in our center in 2007. Retrospective analysis of 201 lung transplant patients, of whom 37 received HELT from 1st July 2007 to 31th May 2012. HELT candidates had a higher impairment grade on respiratory status and higher Lung Allocation Score (LAS). HELT patients had increased incidence of perioperative complications (e.g., perioperative bleeding) and extracorporeal circulatory assistance (75% vs. 36.6%, P = 0.0005). No significant difference was observed between HELT and non-HELT patients in mechanical ventilation duration (15.5 days vs. 11 days, P = 0.27), intensive care unit length of stay (15 days vs. 10 days, P = 0.22) or survival rate at 12 (81% vs. 80%), and 24 months post-LT (72.9% vs. 75.0%). Lastly, mortality on the waiting list was spectacularly reduced from 19% to 2% when compared to the non-HELT 2004-2007 group. Despite a more severe clinical status of patients on the waiting list, HELT provided similar results to conventional LT. These results were associated with a dramatic reduction in the mortality rate of patients on the waiting list.

    To investigate the role of the vagus nerve in acute inflammatory and cardiorespiratory responses to diesel particulate (DP) in the rat airway, we measured changes in respiration, blood pressure and neutrophils in lungs of urethane anesthetized Wistar rats 6-h post-instillation of DP (500 {mu}g) and studied the effect of mid-cervical vagotomy or atropine (1 mg kg{sup -1}) pre-treatment. In conscious rats, we investigated DP, with and without atropine pre-treatment. DP increased neutrophil level in BAL (bronchoalveolar lavage) fluid from intact anesthetized rats to 2.5 {+-} 0.7 x 10{sup 6} cells (n = 8), compared with saline instillation (0.3 {+-} 0.1 x 10{sup 6}, n = 7; P < 0.05). Vagotomy reduced DP neutrophilia to 0.8 {+-} 0.2 x 10{sup 6} cells (n = 8; P < 0.05 vs. intact); atropine reduced DP-induced neutrophilia to 0.3 {+-} 0.2 x 10{sup 6} (n = 4; P < 0.05). In conscious rats, DP neutrophilia of 8.5 {+-} 1.8 x 10{sup 6}, n = 4, was reduced by pre-treatment with atropine to 2.2 {+-} 1.2 x 10{sup 6} cells, n = 3. Hyperventilation occurred 6 h after DP in anesthetized rats with intact vagi, but not in bilaterally vagotomized or atropine pre-treated animals and was abolished by vagotomy (P < 0.05, paired test). There were no significant differences in the other variables (mean blood pressure, heart rate and heart rate variability) measured before and 360 min after DP. In conclusion, DP activates a pro-inflammatory vago-vagal reflex which is reduced by atropine. Muscarinic ACh receptors in the rat lung are involved in DP-induced neutrophilia, and hence muscarinic antagonists may reduce airway and/or cardiovascular inflammation evoked by inhaled atmospheric DP in susceptible individuals.

    2015-08-01

    In April 2014, the American Journal of Transplantation published a report on the first lung transplant in the United States recovered from an uncontrolled donation after circulatory determination of death donor (uDCDD), assessed by ex vivo lung perfusion (EVLP). The article identified logistical and ethical issues related to introduction of lung transplant from uDCDDs. In an open clinical trial, we have Food and Drug Administration and Institutional Review Board approval to transplant lungs recovered from uDCDDs judged suitable after EVLP. Through this project and other experiences with lung recovery from uDCDDs, we have identified solutions to many logistical challenges and have addressed ethical issues surrounding lung transplant from uDCDDs that were mentioned in this case report. Here, we discuss those challenges, including issues related to recovery of other solid organs from uDCDDs. Despite logistical challenges, uDCDDs could solve the critical shortage of lungs for transplant. Furthermore, by avoiding the deleterious impact of brain death and days of positive pressure ventilation, and by using opportunities to treat lungs in the decedent or during EVLP, lungs recovered from uDCDDs may ultimately prove to be better than lungs currently being transplanted from conventional brain-dead organ donors.

    The growing demand for suitable lungs for transplantation drives the quest for alternative strategies to expand the donor pool. The aim of this study is to evaluate the outcomes of lung transplantation (LTx) with donation after circulatory determination of death (DCDD) and the impact of selective ex vivo lung perfusion (EVLP). From 2007 to 2013, 673 LTx were performed, with 62 (9.2%) of them using DCDDs (seven bridged cases). Cases bridged with mechanical ventilation/extracorporeal life support were excluded. From 55 DCDDs, 28 (51%) underwent EVLP. Outcomes for LTx using DCDDs and donation after neurological determination of death (DNDD) donors were similar, with 1 and 5-year survivals of 85% and 54% versus 86% and 62%, respectively (p = 0.43). Although comparison of survival curves between DCDD + EVLP versus DCDD-no EVLP showed no significant difference, DCDD + EVLP cases presented shorter hospital stay (median 18 vs. 23 days, p = 0.047) and a trend toward shorter length of mechanical ventilation (2 vs. 3 days, p = 0.059). DCDDs represent a valuable source of lungs for transplantation, providing similar results to DNDDs. EVLP seems an important technique in the armamentarium to safely increase lung utilization from DCDDs; however, further studies are necessary to better define the role of EVLP in this context.

    This paper describes the initial clinical experience of ex vivo lung perfusion (EVLP) at the Fondazione Ca' Granda in Milan between January 2011 and May 2013. EVLP was considered if donor PaO2 /FiO2 was below 300 mmHg or if lung function was doubtful. Donors with massive lung contusion, aspiration, purulent secretions, pneumonia, or sepsis were excluded. EVLP was run with a low-flow, open atrium and low hematocrit technique. Thirty-five lung transplants from brain death donors were performed, seven of which after EVLP. EVLP donors were older (54 ± 9 years vs. 40 ± 15 years, EVLP versus Standard, P < 0.05), had lower PaO2 /FiO2 (264 ± 78 mmHg vs. 453 ± 119 mmHg, P < 0.05), and more chest X-ray abnormalities (P < 0.05). EVLP recipients were more often admitted to intensive care unit as urgent cases (57% vs. 18%, P = 0.05); lung allocation score at transplantation was higher (79 [40-84] vs. 39 [36-46], P < 0.05). After transplantation, primary graft dysfunction (PGD72 grade 3, 32% vs. 28%, EVLP versus Standard, P = 1), mortality at 30 days (0% vs. 0%, P = 1), and overall survival (71% vs. 86%, EVLP versus Standard P = 0.27) were not different between groups. EVLP enabled a 20% increase in available donor organs and resulted in successful transplants with lungs that would have otherwise been rejected (ClinicalTrials.gov number: NCT01967953).

    Airway complications after lung transplant are relatively common although the rates vary according to the different studies. Pathogenesis is diverse but the principal mechanism is usually bronchus intermedius ischemia in the post-transplant period. One major complication is bronchial stenosis, with relatively frequent involvement of the bronchus intermedius in the case of right lung transplantation. Various treatments have been proposed for bronchus intermedius stenosis, such as endobronchial balloon dilation, laser, cryosurgery and bronchial stents. We present two cases of lung transplant recipients with bronchus intermedius stenosis treated with a Montgomery stent or T-stent, commonly used for tracheal stenosis, who showed positive clinical and functional response.

    Background: Cystic fibrosis (CF) is one of the leading indications for lung transplantation. The incidence and pre-lung transplant risk factors for posttransplant renal dysfunction in the CF population remain undefined. Methods: We conducted a cohort study using adults (≥ 18 years old) in the CF Foundation Patient Registry from 2000 to 2008 to determine the incidence of post-lung transplant renal dysfunction, defined by an estimated glomerular filtration rate of < 60 mL/min/1.73 m2. Multivariable Cox proportional hazards modeling was used to identify independent pretransplant risk factors for post-lung transplant renal dysfunction. Results: The study cohort included 993 adult lung transplant recipients with CF, with a median follow-up of 2 years. During the study period, 311 individuals developed renal dysfunction, with a 2-year risk of 35% (95% CI, 32%-39%). Risk of posttransplant renal dysfunction increased substantially with increasing age (25 to < 35 years vs 18 to < 25 years: hazard ratio [HR], 1.60; 95% CI, 1.15-2.23; vs ≥ 35 years: HR, 2.45; 95% CI, 1.73-3.47) and female sex (HR, 1.56; 95% CI, 1.22-1.99). CF-related diabetes requiring insulin therapy (HR, 1.30; 95% CI, 1.02-1.67) and pretransplant renal function impairment (estimated glomerular filtration rate, 60-90 mL/min/m2 vs > 90 mL/min/m2: HR, 1.58; 95% CI, 1.19-2.12) also increased the risk of posttransplant renal dysfunction. Conclusions: Renal dysfunction is common following lung transplant in the adult CF population. Increased age, female sex, CF-related diabetes requiring insulin, and pretransplant renal impairment are significant risk factors. PMID:22222189

    PURPOSE Pleuroparenchymal fibroelastosis (PPFE) is a rare form of interstitial pneumonia, characterized by elastotic fibrosis involving the pleura and subpleural parenchyma, predominantly in the upper lobes. PPFE can be either idiopathic or secondary and mostly occurs as a late complication of lung or hematopoietic stem cell transplantation (HSCT). The aim of this study was to evaluate the prevalence of secondary forms in transplant recipients. METHODS An expert thoracic radiologist retrospectively reviewed high-resolution computed tomography exams of 700 HSCT recipients and 53 lung transplant recipients from the database of the Radiology Department of S. Orsola-Malpighi Hospital dating back from 2007. For each case that radiologically fulfilled PPFE criteria, the following details were retrieved: clinical characteristics, laboratory and functional data, pathologic findings (obtained from one patient) and metabolic data (obtained from three patients). RESULTS Six cases clinically and radiologically consistent with PPFE were identified: two HSCT recipients (0.28%) and four lung transplant recipients (7.54%). CONCLUSION In this study, PPFE was strongly associated with lung transplants as a late complication, with a prevalence of 7.54%. PMID:27460284

    Lung transplant for cystic fibrosis has been considered contraindicated in patients who have Burkholderia Cenocepacia infection. A 24-year-old white woman who had cystic fibrosis presented with respiratory failure caused by B. Cenocepacia pneumonia. She was treated with broad-spectrum antibiotics and a double-lung transplant. The chest cavity and both bronchi were irrigated with 0.5% povidone-iodine solution. For immunosuppression, she received induction therapy with alemtuzumab (15 mg) and methylprednisolone and maintenance therapy with tacrolimus, mycophenolate mofetil, and prednisone (5 mg daily). Postoperative antibiotics included intravenous meropenem for 3 weeks; vancomycin for 10 days; and inhaled ceftazidime, oral trimethoprim-sulfamethoxazole, and doxycycline for several months. Follow-up at 25 months after transplant showed that chest radiographs were clear and lung function was normal. At 6 years after transplant, she was working full time and had no recurrence of infection from B. Cenocepacia. This case suggests that patients who have cystic fibrosis and active B. Cenocepacia pneumonia may be successfully treated with a lung transplant. PMID:25299375

    Longitudinal data were analysed on the lung function of 25 of 29 survivors of childhood leukaemia or lymphoma, who had been conditioned with cyclophosphamide and total body irradiation before allogeneic bone marrow transplantation, to test whether children are particularly vulnerable to pulmonary damage after transplantation. None developed chronic graft-versus-host disease. Transfer factor and lung volumes were reduced immediately after bone marrow transplantation, but increased during the following years. However, at the last follow up, 4-13 years (median 8) after transplantation, patients had significantly reduced transfer factor, total lung capacity, and forced vital capacity (-1.0, -1.2, and -0.8 SD score, respectively), and increased ratio of forced expiratory volume in one second to forced vital capacity (+0.9 SD score). None of the patients had pulmonary symptoms, and changes were unrelated to their age at bone marrow transplantation. In conclusion, patients had subclinical restrictive pulmonary disease at a median of eight years after total body irradiation and allogeneic bone marrow transplantation.

    We report five cases of diffuse periostitis resembling hypertrophic osteoarthropathy and perostitis deformans in lung transplantation patients on chronic voriconazole, a fluoride-containing compound. Although drug-related periostitis has long been known, the association of lung transplant medication with periostitis was only recently introduced in the literature. To our knowledge, imaging findings have not been fully characterized in the radiology literature. Imaging features along with clinical history help to distinguish this benign condition from other disease entities. In this article, we review the current literature and illustrate the variety of imaging characteristics of this entity so that interpreting radiologists can make accurate diagnoses and avoid unnecessary work up.

    Our objective was to determine the levels of lactate dehydrogenase, IL-6, IL-8, and VEGF, as well as the total and differential cell counts, in the pleural fluid of lung transplant recipients, correlating those levels with the occurrence and severity of rejection. We analyzed pleural fluid samples collected from 18 patients at various time points (up to postoperative day 4). The levels of IL-6, IL-8, and VEGF tended to elevate in parallel with increases in the severity of rejection. Our results suggest that these levels are markers of acute graft rejection in lung transplant recipients. PMID:25210966

    Total body irradiation (TBI) is considered an integral part of the preparation of patients with hematological malignancies for marrow transplantation. One of the major causes of death following bone marrow transplantation is interstitial pneumonia. Its pathogenesis is complex but radiation may play a major role in its development. Computed tomography (CT) has been used in animal and human studies as a sensitive non-invasive method for detecting changes in the lung following radiotherapy. In the present study CT scans are studied before and up to 1 year after TBI. Average lung densities measured before TBI showed large variations among the individual patients. On follow-up scans, lung density decreases were measured for patients who did not develop lung complications. Significant lung density increases were measured in patients who subsequently had lung complications. These lung density increases were observed prior to the onset of respiratory complications and could be correlated with the clinical course of the patients, suggesting the possibility for the usage of CT lung densitometry to predict lung complications before the onset of clinical symptoms.

    Fungal infections are common in solid organ transplantation. An increasing number of transplant recipients receive antifungal therapy for prolonged duration owing to invasive fungal infections. Herein, we describe a diagnosis of periostitis as a complication of chronic use of voriconazole in a lung transplant recipient. The patient was diagnosed with probable pulmonary aspergillosis and was treated with oral voriconazole for a total of 9 months. Evidence of multifocal periostitis was observed in the axial and appendicular skeleton. Early recognition of this phenomenon is important to prevent unnecessary tests and procedures. Prompt discontinuation of voriconazole should result in improvement of symptoms.

    AIM: To performed remains a subject of debate and is the principal aim of the study. METHODS: This retrospective analysis included 73 patients with emphysema (2000-2012). The outcomes of patients undergoing single-lung transplantation (SL) (n = 40) or double-lung transplant (DL) (n = 33) were compared in a Cox multivariate analysis to study the impact of the technique, postoperative complications and acute and chronic rejection on survival rates. Patients were selected for inclusion in the waiting list according to the International Society of Heart Lung Transplantation criteria. Pre and postoperative rehabilitation and prophylaxis, surgical technique and immunosuppressive treatment were similar in every patients. Lung transplantation waiting list information on a national level and retrospective data on emphysema patient survival transplanted in Spain during the study period, was obtained from the lung transplantation registry managed by the National Transplant Organization (ONT). RESULTS: Both groups were comparable in terms of gender and clinical characteristics. We found significant differences in the mean age between the groups, the DL patients being younger as expected from the inclusion criteria. Perioperative complications occurred in 27.6% SL vs 54% DL (P = 0.032). Excluding perioperative mortality, median survival was 65.3 mo for SL and 59.4 mo for DL (P = 0.96). Bronchiolitis obliterans and overall 5-year survival were similar in both groups. Bacterial respiratory infection, cytomegalovirus and fungal infection rates were higher but not significant in SL. No differences were found between type of transplant and survival (P = 0.48). To support our results, national data on all patients with emphysema in waiting list were obtained (n = 1001). Mortality on the waiting list was 2.4% for SL vs 6.2% for DL. There was no difference in 5 year survival between 235 SL and 430 DL patients transplanted (P = 0.875). CONCLUSION: Our results suggest that SL

    Although studies demonstrate that induction therapy improves outcomes after lung transplantation, its influence on survival in patients with chronic obstructive pulmonary disease (COPD) is not clear. The United Network for Organ Sharing database was queried to obtain data regarding adult patients with COPD receiving lung transplant between May 2005 and June 2014. Therapies evaluated include anti-thymocyte globulin, anti-lymphocyte globulin, thymoglobulin, basiliximab, and alemtuzumab. Data were categorized based on receiving induction (INDUCED) and no induction (NONE). Kaplan-Meier plots, Cox proportional hazards models of patient survival, and competing-risks regression models for secondary endpoints were utilized. A total of 3,405 patients who underwent lung transplantation for COPD were enrolled with 1,761 (52%) receiving induction therapy. Of INDUCED, 1,146 (65%) received basiliximab, 380 (22%) received alemtuzumab, and 235 (13%) received a polyclonal preparation. The hazard ratio for INDUCED vs. NONE was 0.793 (95% CI = 0.693, 0.909; p = 0.001) in the fully adjusted Cox model. A multivariable competing-risks model also found a protective influence of induction therapy with respect to delayed onset of bronchiolitis obliterans syndrome after transplantation (SHR = 0.801; 95% CI = 0.694, 0.925; p = 0.003). In a cohort of recently transplanted patients with COPD, there appears to be a benefit from contemporary induction agents with no concurrent increase in the risk of death due to infection.

    After lung transplantation, pulmonary vein thrombosis is a rare, potentially life-threatening adverse event arising at the pulmonary venous anastomosis that typically occurs early and presents as graft failure and hemodynamic compromise with an associated mortality of up to 40%. The incidence, presentation, outcomes, and treatment of late pulmonary vein thrombosis remain poorly defined. Management options include anticoagulant agents for asymptomatic clots, and thrombolytic agents or surgical thrombectomy for hemodynamically significant clots. We present a rare case highlighting a delayed presentation of pulmonary vein thrombosis occurring longer than 2 weeks after lung transplantation and manifesting clinically as graft failure secondary to refractory pulmonary edema. The patient was treated successfully with surgical thrombectomy and remains well. We recommend a high index of suspicion of pulmonary vein thrombosis when graft failure after lung transplantation occurs and is not responsive to conventional therapy, and consideration of investigation with transesophageal echocardiography or computed tomography with venous phase contrast in such patients even more than 2 weeks after lung transplantation.

  15. The Nitric Oxide/Cyclic GMP Pathway in Organ Transplantation: Critical Role in Successful Lung Preservation

    Reestablishment of vascular homeostasis following ex vivo preservation is a critical determinant of successful organ transplantation. Because the nitric oxide (NO) pathway modulates pulmonary vascular tone and leukocyte/endothelial interactions, we hypothesized that reactive oxygen intermediates would lead to decreased NO (and hence cGMP) levels following pulmonary reperfusion, leading to increased pulmonary vascular resistance and leukostasis. Using an orthotopic rat model of lung transplantation, a porphyrinic microsensor was used to make direct in vivo measurements of pulmonary NO. NO levels measured at the surface of the transplanted lung plummeted immediately upon reperfusion, with levels moderately increased by topical application of superoxide dismutase. Because cGMP levels declined in preserved lungs after reperfusion, this led us to buttress the NO pathway by adding a membrane-permeant cGMP analog to the preservation solution. Compared with grafts stored in its absence, grafts stored with supplemental 8-Br-cGMP and evaluated 30 min after reperfusion demonstrated lower pulmonary vascular resistances with increased graft blood flow, improved arterial oxygenation, decreased neutrophil infiltration, and improved recipient survival. These beneficial effects were dose dependent, mimicked by the type V phosphodiesterase inhibitor 2-o-propoxyphenyl-8-azapurin-6-one, and inhibited by a cGMP-dependent protein kinase antagonist, the R isomer of 8-(4-chlorophenylthio)guanosine 3',5'-cyclic monophosphorothioate. Augmenting the NO pathway at the level of cGMP improves graft function and recipient survival following lung transplantation.

    Biomarker profiling is being rapidly incorporated in many areas of modern medical practice to improve the precision of clinical decision-making. This potential improvement, however, has not been transferred to the practice of organ assessment and transplantation because previously developed gene-profiling techniques require an extended period of time to perform, making them unsuitable in the time-sensitive organ assessment process.

    Biomarker profiling is being rapidly incorporated in many areas of modern medical practice to improve the precision of clinical decision-making. This potential improvement, however, has not been transferred to the practice of organ assessment and transplantation because previously developed gene-profiling techniques require an extended period of time to perform, making them unsuitable in the time-sensitive organ assessment process. We sought to develop a novel class of chip-based sensors that would enable rapid analysis of tissue levels of preimplantation mRNA markers that correlate with the development of primary graft dysfunction (PGD) in recipients after transplant. Using fractal circuit sensors (FraCS), three-dimensional metal structures with large surface areas, we were able to rapidly (<20 min) and reproducibly quantify small differences in the expression of interleukin-6 (IL-6), IL-10, and ATP11B mRNA in donor lung biopsies.

    Ischemia-reperfusion injury (IRI) is a common complication after lung transplantation. There is evidence that reactive oxygen species are involved in its pathogenesis. We designed an experimental study to evaluate whether the administration of antioxidants to lung transplantation recipients protects against IRI and early acute rejection (AR). Twenty-five rats received left lung transplants after 6 h of ischemia. Fifty minutes before the reperfusion, groups of five rats received a single dose of desferrioxamine (20 mg/kg), estradiol (25 mg/kg), or melatonin (10 mg/kg). The animals were killed 48 h after surgery and the postoperative outcome, IRI, and AR were evaluated. The frequency of severe injury and of moderate-to-severe edema was higher in animals treated with estradiol than in the control group (P = 0.022 and P = 0.026, respectively). No significant changes in the degree of IRI or AR were observed in the groups treated with desferrioxamine or melatonin. In our study, treatment with the antioxidants melatonin or desferrioxamine before reperfusion had no effects on IRI damage or on AR frequency or severity. However, treatment with estradiol resulted in a worse postoperative outcome and in severe edema. Therefore, despite the antioxidant capacity of estradiol, it is recommended that an evaluation of these adverse effects of estradiol in human lung transplant recipients be performed.

    We report a case of painful, nodular periostitis in a lung transplant recipient on long-term voriconazole therapy. Symptoms, signs, and laboratory abnormalities resolved quickly after drug withdrawal. The presentation more closely resembles periostitis deformans than hypertrophic osteoarthropathy, suggesting that the fluoride moiety of voriconazole may be pathogenic for this condition. Clinicians should be aware of this association.

    Primary graft dysfunction after lung transplantation is the leading cause of morbidity and mortality in the immediate posttransplant period and is characterized by endothelial and epithelial barrier disruption and the leakage of protein-rich edema fluid. Integrins are cell surface receptors that have an important role in maintenance of the cell barrier, and inhibition of integrins, such as αvβ5, can diminish alveolar flooding in lung injury models. We hypothesized that inhibition of αvβ5 during donor lung cold ischemia would reduce endothelial permeability during reperfusion. Using an orthotopic single lung transplantation model with and without cold ischemia, donor lungs were perfused with αvβ5-blocking antibody (ALULA) or control antibody at the time of collection, followed by transplantation, 8 h of reperfusion, and the measurement of lung injury parameters. Prolonged cold ischemia (18 h) produced increases in extravascular lung water, protein permeability, and neutrophilic alveolitis and decreased oxygenation compared with lungs without cold ischemia. Perfusion of lungs with αvβ5 antibody versus control antibody protected donor lungs from injury and significantly improved oxygenation. In summary, αvβ5 integrin blockade protects from the development of ischemia-reperfusion lung injury and is a promising approach to preventing primary graft dysfunction in human lung transplant procedures.

    Lung transplantation (LTx) is a valid therapeutic option for selected patients with end-stage lung disease. HLA-E seems to play a major role in the immune response to different viral infections and to affect transplantation outcome, in Hematopoietic Stem Cell Transplantation, for example. Two nonsynonymous alleles, HLA-E⁎01:01 and HLA-E⁎01:03, have functional differences, involving relative peptide affinity, cell surface expression, and potential lytic activity of NK cells. The aim of this retrospective study was to determine the impact of these two alleles for LTx recipients on anti-HLA alloimmunization risk, overall survival, and chronic rejection (CLAD). HLA-E was genotyped in 119 recipients who underwent LTx from 1998 to 2010 in a single transplantation center. In univariate analysis, both HLA-E homozygous states were associated with impaired overall survival compared to heterozygous HLA-E alleles (p = 0.01). In multivariate analysis, HLA-E⁎01:03 allele showed increased CLAD occurrence when compared to homozygous HLA-E⁎01:01 status (HR: 3.563 (CI 95%, 1.016–12), p = 0.047). HLA-E allele did not affect pathogen infection or the production of de novo DSA. This retrospective study shows an uninvestigated, deleterious association of HLA-E alleles with LTx and requires verification using a larger cohort. PMID:27493971

    Lungs stored ahead of transplant surgery experience ischemia. Pulmonary ischemia differs from ischemia in the systemic organs in that stop of blood flow in the lung leads to loss of shear alone because the lung parenchyma does not rely on blood flow for its cellular oxygen requirements. Our earlier studies on the ischemia-induced mechanosignaling cascade showed that the pulmonary endothelium responds to stop of flow by production of reactive oxygen species (ROS). We hypothesized that ROS produced in this way led to induction of proinflammatory mediators. In this study, we used lungs or cells subjected to various periods of storage and evaluated the induction of several proinflammatory mediators. Isolated murine, porcine and human lungs in situ showed increased expression of cellular adhesion molecules; the damage-associated molecular pattern protein high-mobility group box 1 and the corresponding pattern recognition receptor, called the receptor for advanced glycation end products; and induction stabilization and translocation of hypoxia-inducible factor 1α and its downstream effector VEGFA, all of which are participants in inflammation. We concluded that signaling with lung preservation drives expression of inflammatory mediators that potentially predispose the donor lung to an inflammatory response after transplant. PMID:26998598

    Background: Recent reports have shown evidence of host derived parenchymal engraftment in several human allografts including the lung, leading to speculation that stem cell therapy may be useful for lung repair in diseases such as cystic fibrosis (CF). To date, previous studies have looked at single surgical or autopsy specimens and no longitudinal studies have been reported. The aim of this study was to assess whether transbronchial biopsies could be used to study the time course of chimerism following lung transplantation. Methods: Specimens of archived transbronchial lung biopsies from five time points taken for clinical purposes from two boys who had received a sex mismatched heart-lung transplant for end stage CF were examined. Sections were dual stained for cytokeratin (epithelium) and a mixture of leucocyte common antigen and CD68 for inflammatory cells. Co-localisation of cells containing a Y chromosome was confirmed by fluorescent in situ hybridisation. Results: Evidence of chimerism was found in up to 6.6% of epithelial cells in bronchial (median 1.4% (range 0–6.6)) and alveolar (median 3.6% (range 2.3–5.5) tissue without apparent evidence of fusion. This engraftment was seen as early as 3 weeks and remained relatively constant up to 37 months. Conclusions: This study has demonstrated proof of principle for long term chimerism in lung epithelium. Transbronchial biopsies may provide a new method for studying the kinetics of stem cell engraftment in the lung. PMID:15618585

    Heart-lung transplantation for treatment of end-stage cardiopulmonary disease continues to be plagued by many problems. Three primary ones are the technical difficulties that can be encountered, particularly in those patients who have undergone previous cardiac operations, the additional restriction on donor availability imposed by the lack of satisfactory preservation techniques, and the need for lung size compatibility. Two of these difficulties and others surfaced postoperatively in a heart-lung transplant recipient who presented a series of unique operative and therapeutic challenges. A 42-year-old woman with chronic pulmonary hypertension and previous atrial septal defect repair underwent a heart-lung transplantation in August 1985. The operative procedure was expectedly complicated by bleeding from extensive mediastinal adhesions from the previous sternotomy and bronchial collateralization. Excessive chest tube drainage postoperatively necessitated reoperation to control bleeding from a right bronchial artery tributary. Phrenic nerve paresis, hepatomegaly, and marked abdominal distention caused persistent atelectasis and eventual right lower lobe collapse. Arteriovenous shunting and low oxygen saturation necessitated right lower lobectomy 15 days after transplantation, believed to be the first use of this procedure in a heart-lung graft recipient. Although oxygenation improved dramatically, continued ventilatory support led to tracheostomy. An intensive, psychologically oriented physical therapy program was initiated to access and retrain intercostal and accessory muscles. The tracheostomy cannula was removed after 43 days and gradual weaning from supplemental oxygen was accomplished. During this protracted recovery period, an episode of rejection was also encountered and successfully managed with steroid therapy. The patient continued to progress satisfactorily and was discharged 83 days after transplantation. She is well and active 20 months after discharge.

    Primary graft failure and chronic lung allograft dysfunction (CLAD) limit lung transplant long-term outcomes. Various lung diseases have been correlated with surfactant protein (SP) expression and polymorphisms. We sought to investigate the role of SP expression in lung allografts prior to implantation, in relation to posttransplant outcomes. The expression of SP-(A, B, C, D) mRNA was assayed in 42 allografts. Posttransplant assessments include pulmonary function tests, bronchoscopy, broncho-alveolar lavage fluid (BALF) and biopsies to determine allograft rejection. BALF was assayed for SP-A, SP-D in addition to cytokines IL-8, IL-12 and IL-2. The diagnosis of CLAD was evaluated 6 months after transplantation. Lung allografts with low SP-A mRNA expression prior to implantation reduced survival (Log-rank p < 0.0001). No association was noted for the other SPs. Allografts with low SP-A mRNA had greater IL-2 (p = 0.03) and IL-12 (p < 0.0001) in the BALF and a greater incidence of rejection episodes (p = 0.003). Levels of SP-A mRNA expression were associated with the SP-A2 polymorphisms (p = 0.015). Specifically, genotype 1A1A(0) was associated with lower SP-A mRNA expression (p < 0.05). Lung allografts with low levels of SP-A mRNA expression are associated with reduced survival. Lung allograft SP-A mRNA expression appears to be associated with SP-A gene polymorphisms.

    After the first clinical application of ex vivo lung perfusion in 2001, the technique has been used in many lung transplant centers worldwide. In addition, many modifications have been tested, leading to the development of various ex vivo lung perfusion systems and application protocols. Currently, the Lund protocol, the Toronto protocol, and Organ Care System Lung protocol are the clinically applied ex vivo lung perfusion protocols, based on the favorable results of the safety studies. Accordingly, the comparison among these EVLP systems and protocols should be an important research target, in order to provide the evidence based medical data that would recommend one protocol over the others. In this manuscript, the current experience with EVLP is reviewed and some molecular and clinical targets, that could be used to compare the various protocols of the technique, are introduced.

    Although lung transplantation improves exercise capacity by removal of a ventilatory limitation, recipients' postoperative maximum oxygen uptake (VO2max) remains markedly abnormal. To determine if abnormal skeletal muscle oxidative capacity contributes to this impaired aerobic capacity, nine lung transplant recipients and eight healthy volunteers performed incremental quadriceps exercise to exhaustion with simultaneous measurements of pulmonary gas exchange, minute ventilation, blood lactate, and quadriceps muscle pH and phosphorylation potential by 31P-magnetic resonance spectroscopy (31P-MRS). Five to 38 mo after lung transplantation, peak VO2 was decreased compared with that of normal control subjects (6.7 +/- 0.4 versus 12.3 +/- 1.0 ml/min/kg, p < 0.001), even after accounting for differences in age and lean body weight. Neither ventilation, arterial O2 saturation nor mild anemia could account for the decrease in aerobic capacity. Quadriceps muscle intracellular pH (pH(i)) was more acidic at rest (7.07 +/- 0.01 versus 7.12 +/- 0.01 units, p < 0.05) and fell during exercise from baseline values at a lower metabolic rate (282 +/- 21 versus 577 +/- 52 ml/min, p < 0.001). Regressions for pH(i) versus VO2, phosphocreatine/inorganic phosphate ratio (PCr/Pi) versus VO2, and blood lactate versus pH(i) were not different. Among transplant recipients, the metabolic rate at which pH(i) fell correlated closely with VO2max (r = 0.87, p < 0.01). The persistent decrease in VO2max after lung transplantation may be related to abnormalities of skeletal muscle oxidative capacity. PMID:9032203

    A 63-year-old man was admitted to the hospital with fever and bilateral, peripheral infiltrates. Infectious disease and malignancy seemed to be excluded by fiberoptic diagnostic procedures. Subsequently, respiratory insufficiency developed, making open lung biopsy impossible. The diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) was strongly considered and treatment with corticosteroids was started; this led to dramatic clinical and radiologic improvement for a short time. Eventually, an open lung biopsy specimen disclosed primary extranodal non-Hodgkin's lymphoma of T-cell origin, immunoblastic, of high-grade malignancy according to the Kiel classification. After the first course of chemotherapy, total respiratory insufficiency developed and the patient died. This case is unique in a patient without AIDS.

    Bronchiolitis obliterans is the leading cause of chronic graft failure and long-term mortality in lung transplant recipients. Here, we used a novel murine model to characterize allograft fibrogenesis within a whole-lung microenvironment. Unilateral left lung transplantation was performed in mice across varying degrees of major histocompatibility complex mismatch combinations. B6D2F1/J (a cross between C57BL/6J and DBA/2J) (Haplotype H2b/d) lungs transplanted into DBA/2J (H2d) recipients were identified to show histopathology for bronchiolitis obliterans in all allogeneic grafts. Time course analysis showed an evolution from immune cell infiltration of the bronchioles and vessels at day 14, consistent with acute rejection and lymphocytic bronchitis, to subepithelial and intraluminal fibrotic lesions of bronchiolitis obliterans by day 28. Allografts at day 28 showed a significantly higher hydroxyproline content than the isografts (33.21 ± 1.89 versus 22.36 ± 2.33 μg/mL). At day 40 the hydroxyproline content had increased further (48.91 ± 7.09 μg/mL). Flow cytometric analysis was used to investigate the origin of mesenchymal cells in fibrotic allografts. Collagen I–positive cells (89.43% ± 6.53%) in day 28 allografts were H2Db positive, showing their donor origin. This novel murine model shows consistent and reproducible allograft fibrogenesis in the context of single-lung transplantation and represents a major step forward in investigating mechanisms of chronic graft failure.

    Bronchiolitis obliterans (BO) is a serious complication of allogeneic hematopoietic stem cell transplantation (HSCT). Lung biopsy is the gold standard for diagnosis. This study describes the course of BO and assesses the congruity between biopsy-verified BO and a modified version of the National Institutes of Health's consensus criteria for BO syndrome (BOS) based exclusively on noninvasive measures. We included 44 patients transplanted between 2000 and 2010 who underwent lung biopsy for suspected BO. Of those, 23 were diagnosed with BO and 21 presented other noninfectious pulmonary pathologies, such as cryptogenic organizing pneumonia, diffuse alveolar damage, interstitial pneumonia, and nonspecific interstitial fibrosis. Compared with patients with other noninfectious pulmonary pathologies, BO patients had significantly lower values of forced expiratory volume in 1 second (FEV1), FEV1/forced vital capacity, and maximal mid-expiratory flow throughout follow-up, but there was no difference in the change in pulmonary function from the time of lung biopsy. The BO diagnosis was not associated with poorer overall survival. Fifty-two percent of patients with biopsy-verified BO and 24% of patients with other noninfectious pulmonary pathology fulfilled the BOS criteria. Pathological BO diagnosis was not superior to BOS criteria in predicting decrease in pulmonary function beyond the time of biopsy. A lung biopsy may provide a characterization of pathological patterns that can extend our knowledge on the pathophysiology of HSCT-related lung diseases. PMID:25498923

    Primary graft dysfunction is a leading cause of morbimortality in the immediate postoperative period of patients undergoing lung transplantation. Among the treatment options are: lung protective ventilatory strategies, nitric oxide, lung surfactant therapy, and supportive treatment with extracorporeal membrane oxygenation (ECMO) as a bridge to recovery of lung function or re-transplant. We report the case of a 9-year-old girl affected by cystic fibrosis who underwent double-lung transplantation complicated with a severe primary graft dysfunction in the immediate postoperative period and refractory to standard therapies. Due to development of multiple organ failure, it was decided to insert arteriovenous ECMO catheters (pulmonary artery-right atrium). The postoperative course was satisfactory, allowing withdrawal of ECMO on the 5th post-surgical day. Currently the patient survives free of rejection and with an excellent quality of life after 600 days of follow up. PMID:23731837

    Background Multiple independent culture-based studies have identified the presence of Pseudomonas aeruginosa in respiratory samples as a positive risk factor for bronchiolitis obliterans syndrome (BOS). Yet, culture-independent microbiological techniques have identified a negative association between Pseudomonas species and BOS. Our objective was to investigate whether there may be a unifying explanation for these apparently dichotomous results. Methods We performed bronchoscopies with bronchoalveolar lavage (BAL) on lung transplant recipients (46 procedures in 33 patients) and 26 non-transplant control subjects. We analyzed bacterial communities in the BAL fluid using qPCR and pyrosequencing of 16S rRNA gene amplicons and compared the culture-independent data with the clinical metadata and culture results from these subjects. Findings Route of bronchoscopy (via nose or via mouth) was not associated with changes in BAL microbiota (p = 0.90). Among the subjects with positive Pseudomonas bacterial culture, P. aeruginosa was also identified by culture-independent methods. In contrast, a distinct Pseudomonas species, P. fluorescens, was often identified in asymptomatic transplant subjects by pyrosequencing but not detected via standard bacterial culture. The subject populations harboring these two distinct pseudomonads differed significantly with respect to associated symptoms, BAL neutrophilia, bacterial DNA burden and microbial diversity. Despite notable differences in culturability, a global database search of UM Hospital Clinical Microbiology Laboratory records indicated that P. fluorescens is commonly isolated from respiratory specimens. Interpretation We have reported for the first time that two prominent and distinct Pseudomonas species (P. fluorescens and P. aeruginosa) exist within the post-transplant lung microbiome, each with unique genomic and microbiologic features and widely divergent clinical associations, including presence during acute infection

    Successful lung transplantation (LTx) depends on multiple components of healthcare delivery and performance. Therefore, we conducted an international registry analysis to compare post-LTx outcomes for cystic fibrosis (CF) patients using the UNOS registry in the United States and the National Health Service (NHS) Transplant Registry in the United Kingdom. Patients with CF who underwent lung or heart-lung transplantation in the United States or United Kingdom between January 1, 2000 and December 31, 2011 were included. The primary outcome was all-cause mortality. Kaplan-Meier analysis and Cox proportional hazards regression evaluated the effect of healthcare system and insurance on mortality after LTx. 2,307 US LTx recipients and 451 individuals in the United Kingdom were included. 894 (38.8%) US LTx recipients had publically funded Medicare/Medicaid insurance. US private insurance and UK patients had improved median predicted survival compared with US Medicare/Medicaid recipients (p < 0.001). In multivariable Cox regression, US Medicare/Medicaid insurance was associated with worse survival after LTx (US private: HR0.78,0.68-0.90,p = 0.001 and UK: HR0.63,0.41-0.97, p = 0.03). This study in CF patients is the largest comparison of LTx in two unique health systems. Both the United States and United Kingdom have similar early survival outcomes, suggesting important dissemination of best practices internationally. However, the performance of US public insurance is significantly worse and may put patients at risk.

    Inhalation of nitric oxide (NO) has been advocated as a method to prevent ischemia-reperfusion injury after lung transplantation. We enrolled 84 patients into a concealed, randomized, placebo-controlled trial to evaluate the effect of inhaled NO (20 ppm NO or nitrogen) initiated 10 minutes after reperfusion on outcomes after lung transplantation. The groups (n = 42) were balanced with respect to age, sex, lung disease, procedure, and total ischemic times. PaO2/FIO2 ratios were similar on admission to the intensive care unit (ICU) (NO 361 +/- 134; control patients 357 +/- 132), and over the duration of the study. There were no differences in hemodynamics between the two groups. Severe reperfusion injury (PaO2/FIO2 < 150) was present at the time of admission to the ICU in 14.6% NO patients versus 9.5% of control patients (p = 0.48). The groups had similar median times to first successful trial of unassisted breathing (25 vs. 27 hours; p = 0.76), successful extubation (32 vs. 34 hours; p = 0.65), ICU discharge (3.0 days for both groups), and hospital discharge (27 vs. 29 days; p = 0.563). Five NO versus six control patients died during their hospital stay. Adjusting for age, sex, lung disease etiology, presence of pulmonary hypertension, and total ischemic time did not alter these results. In conclusion, we did not detect a significant effect of inhaled NO administered 10 minutes after reperfusion on physiologic variables or outcomes in lung transplant patients.

The main indications for HTX are non-ischemic dilatative (54%) and ischemic (37%) heart failure. In the acute phase after HTX the survival rate is approximately 90%. Good short and long-term results with survival rates ranging from 81% after 1 year to more than 50% after 11 years demonstrate that there is currently no real treatment alternative to HTX for treatment of end-stage heart failure. In the case of irreversible pulmonary hypertension in combination with end-stage heart failure or complex congenital heart syndromes, a combined heart and lung transplantation (HLTX) is necessary. Compared with HTX the short-term survival of HLTX is reduced, mostly for technical reasons. Improved long-term results after HTX and HLTX are a result of highly specialized transplantation units and effective immunosuppression. However, a major problem is the shortage of organ donors in Germany and the resulting long waiting times for patients with frequently occurring blood groups of up to 10 months for transplantation. The consequence of the latter is the ever increasing number of implanted cardiac assist devices in patients not only as a bridge to transplant but also as destination therapy. PMID:24452762

    Bronchiolitis obliterans syndrome (BOS), a process of fibro-obliterative occlusion of the small airways in the transplanted lung, is the most common cause of lung transplant failure. We tested the role of cell-mediated immunity to collagen type V [col(V)] in this process. PBMC responses to col(II) and col(V) were monitored prospectively over a 7-year period. PBMCs from lung transplant recipients, but not from healthy controls or col(IV)-reactive Goodpasture's syndrome patients after renal transplant, were frequently col(V) reactive. Col(V)-specific responses were dependent on both CD4+ T cells and monocytes and required both IL-17 and the monokines TNF-alpha and IL-1beta. Strong col(V)-specific responses were associated with substantially increased incidence and severity of BOS. Incidences of acute rejection, HLA-DR mismatched transplants, and induction of HLA-specific antibodies in the transplant recipient were not as strongly associated with a risk of BOS. These data suggest that while alloimmunity initiates lung transplant rejection, de novo autoimmunity mediated by col(V)-specific Th17 cells and monocyte/macrophage accessory cells ultimately causes progressive airway obliteration.

    We describe an unusual presentation of metastatic lung adenocarcinoma as malignant retroperitoneal fibrosis (MRPF). The diagnostic challenge, due to the small solitary lung mass and absence of a discrete retroperitoneal mass, was overcome by diagnostic laparoscopy. Molecular analysis of tissue acquired was positive for ALK gene rearrangement. Treatment of the patient with crizotinib reversed MRPF. He was weaned off the nephrostomy tubes and is with stable renal function 11 months after diagnosis. PMID:23914266

    Obliterative bronchiolitis is a frequent, morbid, and usually refractory complication of lung transplantation. Mechanistic study of obliterative bronchiolitis would be aided by development of a relevant model that uses human immune effector cells and airway targets. Our objective was to develop a murine chimera model that mimics obliterative bronchiolitis of lung allograft recipients in human airways in vivo. Human peripheral blood mononuclear cells were adoptively transferred to immunodeficient mice lacking activity of T, B, and NK cells, with and without concurrent transplantations of human small airways dissected from allogeneic cadaveric lungs. Chimerism with human T cells occurred in the majority of recipient animals. The chimeric T cells became highly activated, rapidly infiltrated into the small human airway grafts, and caused obliterative bronchiolitis. In contrast, airways implanted into control mice that did not also receive human peripheral blood mononuclear cell transfers remained intact. In vitro proliferation assays indicated that the chimeric T cells had enhanced specific proliferative responses to donor airway alloantigens. This model confirms the critical role of T cells in development of obliterative bronchiolitis among human lung allograft recipients and provides a novel and easily implemented mechanism for detailed, reductionist in vivo studies of human T-cell responses to allogeneic human small airways.

    The aim of the present study was to assess the effect of lung transplantation (LgTX) on health-related quality of life (HRQL) in a group of patients with cystic fibrosis (CF), compared to patients with other diagnoses (non-CF). HRQL was assessed before transplantation in a group of 32 CF patients and 183 non-CF patients. After LgTX, we conducted a prospective longitudinal study among 10 CF patients and 35 non-CF patients who survived at least 31 months after LgTX. Measures were the Nottingham Health Profile (NHP), the State-Trait Anxiety Inventory (STAI), the Self-Rating Depression Scale (ZUNG), the Index of Well-Being (IWB), and the Karnofsky Performance Index. Patients in the CF group were younger, spent more days on the waiting list, and were more likely to be working or going to school than patients with other indications. Before transplantation, CF patients and non-CF patients experienced restrictions on almost all HRQL measures, compared to the general population. On the NHP dimensions of mobility and energy, CF patients had significantly better scores than non-CF patients. Between 1-4 months after transplantation, scores on the NHP, ZUNG, and Karnofsky performance indices improved, and STAI and IWB scores even occurred within the reference value in both groups. Significantly better scores in the CF group compared to the non-CF group were found on the NHP dimension of mobility 4 months after transplantation, and on the dimension of sleep 7 and 13 months after transplantation. Scores remained more or less stable over time in both groups. It may be concluded that patients in both groups experience major restrictions in HRQL before transplantation. However, pretransplant non-CF patients experience more restrictions than CF patients. After LgTX, both groups of patients showed substantial improvement in HRQL, and this improvement was maintained until 31 months after LgTX. PMID:15095325

  3. Pulmonary epithelioid hemangioendothelioma accompanied by bilateral multiple calcified nodules in lung

    2011-01-01

    Pulmonary epithelioid hemangioendothelioma (PEH) is a rare vascular tumor. It can present either as one solitary nodule or bilateral multiple nodules, usually without calcification. We describe here an unusual case of PEH in a 42-year-old female with a 6.0 cm dominant mass along with bilateral multiple calcified small nodules measuring 0.2-1.0 cm in diameter with a 25-year plus followup history. Overall histologic findings of the solitary tumor accorded with conventional PEH. While multiple calcified small nodules were composed predominantly of intra-alveolar homogeneously eosinophilic matrix, and only a few bland small cells were embedded in it. This lesion has never been reported in the literature. After comprehensive analysis of morphology, radiography, histochemistry, immunohistochemistry and differential diagnoses, PEH presenting multiple calcified small nodules was confirmed. PMID:21418612

    Abstract Patients who have undergone solid organ transplants are known to have an increased risk of neoplasia compared with the general population. We report our experience using mediastinal irradiation with helical tomotherapy versus three‐dimensional conformal radiation therapy to treat a patient with lung carcinoma 15 years after heart transplantation. Our dosimetric evaluation showed no particular difference between the techniques, with the exception of some organs. Mediastinal irradiation after heart transplantation is feasible and should be considered after evaluation of the risk. Conformal radiotherapy or intensity‐modulated radiotherapy appears to be the appropriate treatment in heart‐transplanted oncologic patients. PMID:27148425

    Up to one in four lung-transplanted patients develop pulmonary infiltrates and impaired oxygenation within the first days after lung transplantation. Known as primary graft dysfunction (PGD), this condition increases mortality significantly. Complex interactions between donor lung and recipient immune system are the suspected cause. We took an integrative, systems-level approach by first exploring whether the recipient's immune response to PGD includes the development of long-lasting autoreactivity. We next explored whether proteins displaying such differential autoreactivity also display differential gene expression in donor lungs that later develop PGD compared with those that did not. We evaluated 39 patients from whom autoantibody profiles were already available for PGD based on chest radiographs and oxygenation data. An additional nine patients were evaluated for PGD based on their medical records and set aside for validation. From two recent donor lung gene expression studies, we reanalysed and paired gene profiles with autoantibody profiles. Primary graft dysfunction can be distinguished by a profile of differentially reactive autoantibodies binding to 17 proteins. Functional analysis showed that 12 of these proteins are part of a protein–protein interaction network (P=3 × 10−6) involved in proliferative processes. A nearest centroid classifier assigned correct PGD grades to eight out of the nine patients in the validation cohort (P=0·048). We observed significant positive correlation (r=0·63, P=0·011) between differences in IgM reactivity and differences in gene expression levels. This connection between donor lung gene expression and long-lasting recipient IgM autoantibodies towards a specific set of proteins suggests a mechanism for the development of autoimmunity in PGD.

    A 68-year-old female was admitted to our hospital with an acute episode of chest pain, progressive cough and fever. She underwent trans-subxiphoid video-assisted thoracoscopic extended thymectomy (TsVATET) for thymoma with myasthenia gravis (MG) 9 days ago. Chest computed tomography (CT) showed anterior mediastinal oedema, and infiltrative findings involved bilateral lung. Physical examination revealed the subxiphoid wound suppuration. We diagnosed subxiphoid incision infection, anterior mediastinitis and concomitant bilateral pneumonia. Using antibiotics intravenously combined with anterior mediastinum irrigation and drainage, she felt well but bilateral multiple lung abscesses were discovered on the 12th day of hospitalisation. After conservative treatment with antibiotics and wound care, the recovery was satisfactory and she discharged home. In our experience, because the subxiphoid incision, the anterior mediastinum and the bilateral thoracic cavity communicated directly after TsVATET, we should be aware of the risk of anterior mediastinitis, the infection of bilateral pleural cavity, pneumonia and multiple lung abscesses following subxiphoid incision infection.

    In patients awaiting lung transplantation (LTX), adequate gas exchange may not be sufficiently achieved by mechanical ventilation alone if acute respiratory decompensation arises. We report on 20 patients with life-threatening hypercapnia who received extracorporeal CO2 removal (ECCO2-R) by means of the interventional lung assist (ILA®, Novalung) as bridge to LTX. The most common underlying diagnoses were bronchiolitis obliterans syndrome, cystic fibrosis, and idiopathic pulmonary fibrosis, respectively. The type of ILA was pumpless arteriovenous or pump-driven venovenous (ILA activve®, Novalung) in 10 patients each. ILA bridging was initiated in 15 invasively ventilated and five noninvasively ventilated patients, of whom one had to be intubated prior to LTX. Hypercapnia and acidosis were effectively corrected in all patients within the first 12 h of ILA therapy: PaCO2 declined from 109 (70-146) to 57 (45-64) mmHg, P < 0.0001; pH increased from 7.20 (7.06-7.28) to 7.39 (7.35-7.49), P < 0.0001. Four patients were switched to extracorporeal membrane oxygenation due to progressive hypoxia or circulatory failure. Nineteen patients (95%) were successfully transplanted. Hospital and 1-year survival was 75 and 72%, respectively. Bridging to LTX with ECCO2-R delivered by arteriovenous pumpless or venovenous pump-driven ILA is feasible and associated with high transplantation and survival rates.

    Background: Caregivers are a vital resource in the care of transplant candidates or recipients. However, few strategies have been tested that attempt to decrease the stress and anxiety they commonly encounter. Objective: To test the feasibility of using mindfulness-based stress reduction (MBSR) techniques to decrease stress and anxiety in caregivers of lung transplant candidates/recipients who required admission to an acute care facility. Methods: 30 caregivers of lung transplant candidates/recipients were recruited during hospitalization of their significant other. Each completed the perceived stress scale (PSS) and state trait anxiety inventory (STAI) before and 4 weeks after receiving a DVD that demonstrated MBSR techniques. Participants were asked to practice MBSR techniques for 5–15 min a day for 4 weeks. Results: The participants had a mean±SD age of 55.6±13.6 years; 77% of participants were female and 93% Caucasian. The mean PSS and STAI (trait and anxiety) scores of caregivers were higher than population norms pre- and post-intervention. Scores for caregivers who stated they watched the entire DVD and practiced MBSR techniques as requested (n=15) decreased significantly from pre- to post-testing for perceived stress (p=0.001), state anxiety (p=0.003) and trait anxiety (p=0.006). Scores for those who watched some or none of the DVD (n=15) did not change significantly. Conclusion: Caregivers can benefit from stress reduction techniques using MBSR. PMID:25013679

    Context-Lung transplant recipients are encouraged to perform self-management behaviors to maximize health outcomes; however, performance is often less than ideal. Goal orientation is known to influence achievement of academic goals, but the influence of goal orientation on performance of self-management is unknown. Objectives-To identify characteristics at transplant that are predictive of higher goal orientation and examine relationships between Goal Orientation Index (GOI) subscores (Acting, Planning, Reflecting), self-management behaviors (adhering, self-monitoring, and communicating critical changes), and health-related quality of life (HRQOL) at 1 year after transplant. Design-A descriptive, secondary analysis of data from 33 lung transplant recipients who were assessed at transplant and followed for 1 year as part of a clinical trial. GOI subscores were dichotomized at the median to categorize recipients with high and low goal orientation. Logistic regression was used to identify predictors of higher GOI subscores. Correlations between higher GOI subscores, self-management, and HRQOL were examined. Results-Lung transplant recipients reported relatively high mean GOI subscores (Acting, Planning, and Reflecting) and the 3 subscores were correlated (r=0.31-0.86). Self-care agency was the only significant predictor (P=.04) of higher GOI (Reflecting). Lung transplant recipients with higher Planning and Reflecting subscores were more likely to adhere (r = 0.36 and 0.46, respectively). Recipients with higher GOI subscores reported significantly better mental HRQOL (r = 0.42-0.36). Recipients with higher GOI Planning or Acting subscores reported significantly less anxiety (r = -0.39-0.46) and fewer depressive symptoms (r = -0.40-0.43). Conclusion-Assessing goal orientation may offer a novel approach for promoting adherence and HRQOL after lung transplant. PMID:26308782

    Abstract Little is known about the physiologic determinants of 6-minute walk distance in idiopathic pulmonary fibrosis. We investigated the demographic, pulmonary function, echocardiographic, and hemodynamic determinants of 6-minute walk distance in patients with idiopathic pulmonary fibrosis evaluated for lung transplantation. We performed a cross-sectional analysis of 130 patients with idiopathic pulmonary fibrosis who completed a lung transplantation evaluation at the Hospital of the University of Pennsylvania between 2005 and 2010. Multivariable linear regression analysis was used to generate an explanatory model for 6-minute walk distance. After adjustment for age, sex, race, height, and weight, the presence of right ventricular dilation was associated with a decrease of 50.9 m (95% confidence interval [CI], 8.4–93.3) in 6-minute walk distance (P=0.02). For each 200-mL reduction in forced vital capacity, the walk distance decreased by 15.0 m (95% CI, 9.0–21.1; P<0.001). For every increase of 1 Wood unit in pulmonary vascular resistance, the walk distance decreased by 17.3 m (95% CI, 5.1–29.5; P=0.006). Six-minute walk distance in idiopathic pulmonary fibrosis depends in part on circulatory impairment and the degree of restrictive lung disease. Future trials that target right ventricular morphology, pulmonary vascular resistance, and forced vital capacity may potentially improve exercise capacity in patients with idiopathic pulmonary fibrosis.

    Systemic sclerosis per se should not be considered as an a priori contraindication for a pre-transplantation assessment in patients with advanced interstitial lung disease and/or pulmonary hypertension. For lung or heart-lung transplantation, a multidisciplinary approach, adapting the pre-transplant assessment to systemic sclerosis and optimizing systemic sclerosis patient management before, during and after surgery should improved the short- and long-term prognosis. Indications and contraindications for transplantation have to be adapted to the specificities of systemic sclerosis. A special focus on the digestive tract involvement and its thorough evaluation are mandatory before transplantation in systemic sclerosis. As the esophagus is almost always involved, isolated gastro-oesophageal reflux disease, pH metry and/or manometry abnormalities should not be a systematic per se contraindication for pre-transplantation assessment. Corticosteroids may be harmful in systemic sclerosis as they are associated with acute renal crisis. A low dose corticosteroids protocol for immunosuppression is therefore advisable in systemic sclerosis.

    Acellular normothermic ex vivo lung perfusion (EVLP) is a novel method of donor lung preservation for transplantation. As cellular metabolism is preserved during perfusion, it represents a potential platform for effective gene transduction in donor lungs. We hypothesized that vector-associated inflammation would be reduced during ex vivo delivery due to isolation from the host immune system response. We compared ex vivo with in vivo intratracheal delivery of an E1-, E3-deleted adenoviral vector encoding either green fluorescent protein (GFP) or interleukin-10 (IL-10) to porcine lungs. Twelve hours after delivery, the lung was transplanted and the post-transplant function assessed. We identified significant transgene expression by 12 hours in both in vivo and ex vivo delivered groups. Lung function remained excellent in all ex vivo groups after viral vector delivery; however, as expected, lung function decreased in the in vivo delivered adenovirus vector encoding GFP (AdGFP) group with corresponding increases in IL-1β levels. Transplanted lung function was excellent in the ex vivo transduced lungs and inferior lung function was seen in the in vivo group after transplantation. In summary, ex vivo delivery of adenoviral gene therapy to the donor lung is superior to in vivo delivery in that it leads to less vector-associated inflammation and provides superior post-transplant lung function.

    The origin and turnover of connective tissue cells in adult human organs, including the lung, are not well understood. Here, studies of cells derived from human lung allografts demonstrate the presence of a multipotent mesenchymal cell population, which is locally resident in the human adult lung and has extended life span in vivo. Examination of plastic-adherent cell populations in bronchoalveolar lavage samples obtained from 76 human lung transplant recipients revealed clonal proliferation of fibroblast-like cells in 62% (106 of 172) of samples. Immunophenotyping of these isolated cells demonstrated expression of vimentin and prolyl-4-hydroxylase, indicating a mesenchymal phenotype. Multiparametric flow cytometric analyses revealed expression of cell-surface proteins, CD73, CD90, and CD105, commonly found on mesenchymal stem cells (MSCs). Hematopoietic lineage markers CD14, CD34, and CD45 were absent. Multipotency of these cells was demonstrated by their capacity to differentiate into adipocytes, chondrocytes, and osteocytes. Cytogenetic analysis of cells from 7 sex-mismatched lung transplant recipients harvested up to 11 years after transplant revealed that 97.2% +/- 2.1% expressed the sex genotype of the donor. The presence of MSCs of donor sex identity in lung allografts even years after transplantation provides what we believe to be the first evidence for connective tissue cell progenitors that reside locally within a postnatal, nonhematopoietic organ.

    Invasive pulmonary aspergillosis is a life-threatening infection in lung transplant recipients; however, no studies of the pharmacokinetics and pharmacodynamics (PKPD) of echinocandins in transplanted lungs have been reported. We conducted a single-dose prospective study of the intrapulmonary and plasma PKPD of 150 mg of micafungin administered intravenously in 20 adult lung transplant recipients. Epithelial lining fluid (ELF) and alveolar cell (AC) samples were obtained via bronchoalveolar lavage performed 3, 5, 8, 18, or 24 h after initiation of infusion. Micafungin concentrations in plasma, ELF, and ACs were determined using high-pressure liquid chromatography. Noncompartmental methods, population analysis, and multiple-dose simulations were used to calculate PKPD parameters. Cmax in plasma, ELF, and ACs was 4.93, 1.38, and 17.41 μg/ml, respectively. The elimination half-life in plasma was 12.1 h. Elevated concentrations in ELF and ACs were sustained during the 24-h sampling period, indicating prolonged compartmental half-lives. The mean micafungin concentration exceeded the MIC90 of Aspergillus fumigatus (0.0156 μg/ml) in plasma (total and free), ELF, and ACs throughout the dosing interval. The area under the time-concentration curve from 0 to 24 h (AUC0-24)/MIC90 ratios in plasma, ELF, and ACs were 5,077, 923.1, and 13,340, respectively. Multiple-dose simulations demonstrated that ELF and AC concentrations of micafungin would continue to increase during 14 days of administration. We conclude that a single 150-mg intravenous dose of micafungin resulted in plasma, ELF, and AC concentrations that exceeded the MIC90 of A. fumigatus for 24 h and that these concentrations would continue to increase during 14 days of administration, supporting its potential activity for prevention and early treatment of pulmonary aspergillosis.

    Activin A, a member of the transforming growth factor β super-family, is a key regulator of multiple biological pathways including the physiological processes of organ development and homeostasis; as well as the pathological processes of inflammation, remodelling and fibrosis. Dysregulation of activin A and its naturally occurring antagonist follistatin, contribute to the development of disease in multiple organ systems. In this review, we summarize the regulation of activin A, its dysregulated expression in a number of respiratory diseases and postulate its potential role in contributing to allograft dysfunction following lung transplantation.

    We present a 62-year old male who underwent right single-lung transplantation. An autologous pericardial rim was constructed at implantation, as there was insufficient donor atrial cuff. The patient was discharged home but deteriorated over 12 months resulting in oxygen dependency. Computed tomography scan showed stenosis of the right inferior pulmonary vein. The patient underwent pulmonary vein angioplasty under general anaesthesia in September 2007, which was successful and resulted in significant improvement in clinical status. However, his symptoms recurred 2 months later and a second attempt at angioplasty failed. He died 6 weeks later. PMID:22611185

    Objectives Ischemia-reperfusion injury(IRI) is a common complication following lung transplantation(LTx). IRI is thought to be mediated by reactive oxygen species(ROS). Hydrogen sulfide(H2S) is a novel agent that has been previously shown to scavenge ROS and slow metabolism. We evaluated the impact of infused H2S on the presence of ROS after reperfusion in an ex vivo model of LTx. Methods Heart-Lung blocks were recovered from New Zealand White rabbits(n=12) and cold stored in Perfadex solution for 18 hours. Following storage, the heart-lung blocks were reperfused ex vivo with donor rabbit blood. In the treatment group(n=7), a bolus of sodium hydrogen sulfide was added at the beginning of reperfusion(100ug/kg) and continuously infused throughout the two hour experiment(1mg/kg/hr). The vehicle group(n=5) received an equivalent volume of saline. Serial airway and pulmonary artery pressures were measured along with arterial and venous blood gases. Results Oxygenation and pulmonary artery pressures were similar between the two groups. However, treatment with H2S resulted in a dramatic reduction in the presence of ROS after 2 hours of reperfusion(4851 ± 2139 vs. 235 ± 462 RFU/mg protein, p=0.003). There was a trend toward increased levels of cGMP in the H2S treated group(3.08 ± 1.69 vs. 1.73 ± 1.41 fmol/mg tissue, p=0.23). Conclusions After prolonged ischemia, infusion of H2S during reperfusion is associated with a significant decrease in the presence of ROS, a suspected mediator of IRI. To our knowledge, this study represents the first reported therapeutic use of H2S in an experimental model of lung transplant. PMID:22464394

    Abstract Etiologies for diffuse alveolar hemorrhage are wide and range from infectious to vasculitis and malignant processes. Idiopathic thrombocytopenic purpura is an autoimmune disorder characterized by persistent thrombocytopenia, with a relatively indolent course in young patients, but a more complicated progression and high associated mortality in the older patients. Diffuse alveolar hemorrhage, complicating idiopathic thrombocytopenic purpura, is a very uncommon association, with only 2 reported cases in the literature. We present a 69-year-old healthy woman presenting with petechial rash, progressive dyspnea, and bilateral alveolar infiltrates. She was found to have idiopathic thrombocytopenic purpura associated with diffuse alveolar hemorrhage. The patient had an excellent response to high doses of pulse steroids and immunoglobulins. A high index of suspicion for noninfectious pulmonary diseases should be considered in patients with autoimmune diseases presenting with pulmonary infiltrates and hypoxia. Flexible bronchoscopy with sequential lavage is a relatively safe procedure in patients with coagulopathy and should be attempted to detect and confirm the diagnosis; absence of hemoptysis should not preclude the diagnosis.

    The first orthotopic heart transplantation (OHT) was performed in 1967 by C.N. Barnard in Cape Town, South Africa. The first OHT in Cuba was performed in 1985. The main purpose of our study was to determine some of the aspects related to the short-, mid-, and long-term morbimortality rates of OHT patients in Cuba. We analyzed the first 120 OHTs (3 heart plus lung transplantations, 4 retransplantations, and 113 heart transplantations) which were performed in Cuba from December 1985 to December 2005. Based on the analysis, we performed a descriptive, retrospective research about morbimortality. There was a predominance of the masculine sex (5.31:1). The overall mean age was 45.13 +/- 11.58 years (range, 14-67 years). The most frequent pretransplant diagnosis was coronary artery disease (CAD; n = 69; 57.5%). Analyzing the Kaplan-Meier survival curve, we observed that the survival probability at 1 year was 83.3%; at 5 years, 45.7%; and at 10 years 19.2%. The complications by frequency were: sepsis (n = 41; 37%), acute rejection episodes (n = 42; 35.0%), and neoplasia (n = 4; 3.3%). Complications in frequency order were sepsis and acute rejection episodes among short term and chronic rejection and chronic renal failure among long-term survivors.

    CD59 is a complement regulatory protein that inhibits membrane attack complex formation. A soluble form of CD59 (sCD59) is present in various body fluids and is associated with cellular damage after acute myocardial infarction. Lung transplantation (LTx) is the final treatment for end-stage lung diseases, however overall survival is hampered by chronic lung allograft dysfunction development, which presents itself obstructively as the bronchiolitis obliterans syndrome (BOS). We hypothesized that, due to cellular damage and activation during chronic inflammation, sCD59 serum levels can be used as biomarker preceding BOS development. We analyzed sCD59 serum concentrations in 90 LTx patients, of whom 20 developed BOS. We observed that BOS patients exhibited higher sCD59 serum concentrations at the time of diagnosis compared to clinically matched non-BOS patients (p = 0.018). Furthermore, sCD59 titers were elevated at 6 months post-LTx (p = 0.0020), when patients had no BOS-related symptoms. Survival-analysis showed that LTx patients with sCD59 titers ≥400 pg/ml 6 months post-LTx have a significant (p < 0.0001) lower chance of BOS-free survival than patients with titers ≤400 pg/ml, 32% vs. 80% respectively, which was confirmed by multivariate analysis (hazard ratio 6.2, p < 0.0001). We propose that circulating sCD59 levels constitute a novel biomarker to identify patients at risk for BOS following LTx.

    The progress of PD and its related disorders cannot be prevented with the medications available. In this study, we recruited 8 PD and 4 PD plus patients between 5 to 15 years after diagnosis. All patients received BM-MSCs bilaterally into the SVZ and were followed up for 12 months. PD patients after therapy reported a mean improvement of 17.92% during "on" and 31.21% during "off" period on the UPDRS scoring system. None of the patients increased their medication during the follow-up period. Subjectively, the patients reported clarity in speech, reduction in tremors, rigidity, and freezing attacks. The results correlated with the duration of the disease. Those patients transplanted in the early stages of the disease (less than 5 years) showed more improvement and no further disease progression than the later stages (11-15 years). However, the PD plus patients did not show any change in their clinical status after stem cell transplantation. This study demonstrates the safety of adult allogenic human BM-MSCs transplanted into the SVZ of the brain and its efficacy in early-stage PD patients. PMID:22550521

    This is a case of atrial tachycardia 2 years after pulmonary transplantation. After excluding right atrial involvement, tachycardia origin was located in a scar region medial to the anastomosis of the left inferior pulmonary donor vein. Tachycardia mechanism was microreentry. Noninvasive electrocardiographic mapping performed before the ablation procedure matched with results of invasive Carto mapping and predicted both tachycardia mechanism and origin. We discuss arrhythmia mechanism found after pulmonary transplantation and benefit of noninvasive electrocardiographic mapping for procedure planning.

    The aim of this study was to compare a continuous non-calibrated left heart cardiac index (CI) measurement by arterial waveform analysis (FloTrac(®)/Vigileo(®)) with a continuous calibrated right heart CI measurement by pulmonary artery thermodilution (CCOmbo-PAC(®)/Vigilance II(®)) for hemodynamic monitoring during lung transplantation. CI was measured simultaneously by both techniques in 13 consecutive lung transplants (n = 4 single-lung transplants, n = 9 sequential double-lung transplants) at distinct time points perioperatively. Linear regression analysis and Bland-Altman analysis with percentage error calculation were used for statistical comparison of CI measurements by both techniques. In this study the FloTrac(®) system underestimated the CI in comparison with the continuous pulmonary arterial thermodilution (p < 0.000). For all measurement pairs we calculated a bias of -0.55 l/min/m(2) with limits of agreement between -2.31 and 1.21 l/min/m(2) and a percentage error of 55 %. The overall correlations before clamping a branch oft the pulmonary artery (percentage error 41 %) and during the clamping periods of a branch oft the pulmonary artery (percentage error 66 %) failed to reached the required percentage error of less than 30 %. We found good agreement of both CI measurements techniques only during the measurement point "15 min after starting the second one-lung ventilation period" (percentage error 30 %). No agreement was found during all other measurement points. This pilot study shows for the first time that the CI of the FloTrac(®) system is not comparable with the continuous pulmonary-artery thermodilution during lung transplantation including the time periods without clamping a branch of the pulmonary artery. Arterial waveform and continuous pulmonary artery thermodilution are, therefore, not interchangeable during these complex operations.

    Objectives: Ischemia-reperfusion(IRI) is a common complication of lung transplantation(LTx). Hydrogen sulfide(H2S) is a novel agent previously shown to slow metabolism and scavenge reactive oxygen species, potentially mitigating IRI. We hypothesized that pre-treatment with inhaled H2S would improve graft function in an ex vivo model of LTx. Methods: Rabbits(n=10) were ventilated for 2 hours prior to heart-lung bloc procurement. The treatment group(n=5) inhaled room air(21% O2) supplemented with 150 ppm H2S while the control group(n=5) inhaled room air alone. Both groups were gradually cooled to 34 C. All heart-lung blocs were then recovered and cold-stored in low potassium dextran solution for 18 hours. Following storage, the blocs were reperfused with donor rabbit blood in an ex vivo apparatus. Serial clinical parameters were assessed and serial tissue biochemistry was examined. Results: Prior to heart-lung bloc procurement, rabbits pre-treated with H2S exhibited similar oxygenation(p=0.1), ventilation(p=0.7), and heart rate(p=0.5); however, treated rabbits exhibited consistently higher mean arterial blood pressures(p=0.01). During reperfusion, lungs pre-treated with H2S had better oxygenation(p<0.01) and ventilation(p=0.02) as well as lower pulmonary artery pressures(p<0.01). Reactive oxygen species levels were lower in treated lungs during reperfusion(p=0.01). Additionally, prior to reperfusion, treated lungs demonstrated more preserved mitochondrial cytochrome c oxidase activity(p=0.01). Conclusions: To our knowledge, this study represents the first reported therapeutic use of inhaled H2S in an experimental model of LTx. After prolonged ischemia, lungs pre-treated with inhaled H2S exhibited improved graft function during reperfusion. Donor pre-treatment with inhaled H2S represents a potentially novel adjunct to conventional preservation techniques and merits further exploration. PMID:22771242

    We encountered a case of a middle-aged woman with systemic lupus erythematosus. As the patient had progressive peripheral neuropathy including foot drop, we intended to treat her with intensive immunosuppressive therapy as soon as possible. Pretreatment assessment, however, revealed multiple nodular lesions in the lungs and bones, suggesting disseminated tumor metastasis or miliary tuberculosis. To our surprise, gallium and bone scintigraphy as well as cytodiagnosis revealed no sign of malignancy or infection, leading us to suspect the presence of another multisystem disorder. The presence of subependymal nodules and a periungual fibroma strongly suggested tuberous sclerosis (TS). A genetic test revealed a mutation in the TSC1 gene and confirmed the diagnosis. Thus, the multiple nodular lesions were most likely a hyperplasia due to TS. Although the odds of a comorbidity of more than one multisystem disorder are considered to be quite low, it should be kept in mind that when such a situation does exist, the comorbidity may make the presenting symptoms extremely diverse.

    Background Aspergillus colonisation is frequently reported after lung transplantation. The question of whether aspergillus colonisation is related to the hospital environment is crucial to prevention. Method To elucidate this question, a prospective study of aspergillus colonisation after lung transplantation, along with a mycological survey of the patient environment, was performed. Results Forty-four consecutive patients were included from the day of lung transplantation and then examined weekly for aspergillus colonisation until hospital discharge. Environmental fungal contamination of each patient was followed weekly via air and surface sampling. Twelve patients (27%) had transient aspergillus colonisation, occurring 1–13 weeks after lung transplantation, without associated manifestation of aspergillosis. Responsible Aspergillus species were A. fumigatus (6), A. niger (3), A. sydowii (1), A. calidoustus (1) and Aspergillus sp. (1). In the environment, contamination by Penicillium and Aspergillus was predominant. Multivariate analysis showed a significant association between occurrence of aspergillus colonisation and fungal contamination of the patient’s room, either by Aspergillus spp. in the air or by A.fumigatus on the floor. Related clinical and environmental isolates were genotyped in 9 cases of aspergillus colonisation. For A. fumigatus (4 cases), two identical microsatellite profiles were found between clinical and environmental isolates collected on distant dates or locations. For other Aspergillus species, isolates were different in 2 cases; in 3 cases of aspergillus colonisation by A. sydowii, A. niger and A. calidoustus, similarity between clinical and environmental internal transcribed spacer and tubulin sequences was >99%. Conclusion Taken together, these results support the hypothesis of environmental risk of hospital acquisition of aspergillus colonisation in lung transplant recipients. PMID:26629994

    Autosomal dominant polycystic disease is a multisystem inherited condition affecting the kidneys and is an important cause of end-stage renal disease. Patients with autosomal dominant polycystic disease experience symptoms related to size and cystic nature of their kidneys, which can be difficult to manage. Traditionally, the only surgical option for management was open bilateral/unilateral native nephrectomy, which carried with it significant morbidity and mortality. Therefore, it was deemed unsafe and rarely performed. However, surgery for autosomal dominant polycystic disease has evolved rapidly with the advent of minimally invasive surgery and improved medical management of end-stage renal failure patients. Laparoscopic and hand-assisted laparoscopic techniques have been adopted and have demonstrated reduced morbidity. The timing of this intervention in relation to transplant is controversial and presents a major challenge in managing this patient population.

    Background Accurate immunosuppression is of critical importance in preventing rejection, while avoiding toxicity following lung transplantation. The mainstay immunosuppressants are calcineurin inhibitors, which require regular monitoring due to interactions with other medications and diet. Adherence to immunosuppression and patient knowledge is vital and can be improved through patient education. Education using tablet-computers was investigated. Objective To compare tablet-PC education and conventional education in improving immunosuppression trough levels in target range 6 months after a single education. Secondary parameters were ratio of immunosuppression level measurements divided by per protocol recommended measurements, time and patient satisfaction regarding education. Design Single-centre, open labelled randomised controlled trial. Participants Patients >6 months after lung-transplantation with <50% of calcineurin inhibitor trough levels in target range. Intervention Tablet-pc education versus personal, nurse-led education. Measurements Calcineurin inhibitor levels in target range 6 months after education, level variability, interval adherence, knowledge and adherence was studied. As outcome parameter, renal function was measured and adverse events registered. Results Sixty-four patients were 1:1 randomised for either intervention. Levels of immunosuppression 6 months after education were equal (tablet-PC 58% vs. conventional 48%, p = 0.27), both groups improved in achieving a CNI trough level within target range by either education method (delta tablet-PC 29% vs. conventional 20%). In all patients, level variability decreased (−20.4%), whereas interval adherence remained unchanged. Knowledge about immunosuppression improved by 7% and compliance tests demonstrated universal improvements with no significant difference between groups. Conclusion Education is a simple, effective tool in improving adherence to immunosuppression. Tablet-PC education was

He was found to have a pulmonary lesion and went on to develop a lung abscess. Propionibacterium acnes was identified on matrix-assisted laser desorption ionisation mass spectrometry-time of flight and 16s rRNA gene sequencing after drainage. He was curatively treated with co-trimoxazole and co-amoxiclav. He divulged a longstanding history of seborrhoeic dermatitis with frequent flares leading to large volumes of squames collecting on his bed sheets. We hypothesise this was a possible route of entry: inhalation of the Propionibacterium. This case highlights how a common commensal bacterium, P. acnes, was able to cause pathology in an immunosuppressed patient. This is the only case of a patient with transplantation developing a P. acnes pulmonary infection and the only case of P. acnes causing these clinical features to be reported in the literature.

    Dogs receiving left unilateral allo- or auto-grafts were treated with Cyclosporin A (Cy A) for 4 days. Thereafter allografted transplant recipients showed pulmonary pathology consistent with rejection. Blood and bronchoalveolar lavage (BAL)-derived lymphocytes were isolated from the recipient animals before and at various times after operation and the frequency of allospecific precursor cytolytic lymphocytes (pCTL) determined by limiting dilution analysis (LDA). Samples from the autografted control animal did not show any post-operative frequency changes; however, both blood and BAL-derived lymphocytes from allografted recipients showed a significant post-operative increase in the proportion of donor-specific pCTL. This increase was consistently greater in samples from the transplanted than the autochthonous lung. The frequency of pCTL determined using targets from an unrelated dog showed no post-operative increase. It is likely that the increase in frequency of donor-specific pCTL recorded during graft-rejection is a specific consequence of an interaction between the graft and recipient's immune system.

    Pulmonary rehabilitation (PR) is a cornerstone of treatment following lung transplantation (LTx). The aim of this study was to observe the influence of a prolonged postsurgical clinical course on success of a 3-week inpatient PR. LTx recipients were divided according to their clinical course defined by their individual length of stay (LOS) in the transplant center (cohort 1: LOS >; cohort 2: ≤42 days). Peak work rate (PWR), maximum oxygen uptake (VO(2max) ), 6-min walk distance (6-MWD), vital capacity (VC), forced expiratory volume in one second (FEV1), physical activity of daily life (ADL), and health-related quality of life (HRQoL) measured using Short Form 36 questionnaire (SF36) were assessed at beginning and completion of PR. A total of 138 patients were included (LOS >42 days: 30; LOS ≤42 days: 108). At completion, physical functioning (VC, FEV1, PWR, VO(2max) , 6-MWD, ADL), and HRQoL (all SF36 domains) improved in each cohort (P < 0.05). No differences were found in between both cohorts in VC, FEV1, and ADL (n.s.), but in PWR, 6-MWD, and the SF36 domain 'physical functioning' (P < 0.05). A 3-week inpatient PR improves physical functioning despite prolonged hospitalization. HRQoL is close to normal. (ClinicalTrials.gov. identifier: NCT00759538).

    Background Lung transplant recipients are expected to perform self-care behaviors to maximize transplant-related health outcomes. Despite high non-adherence rates in performing these self-care behaviors, and the dire clinical consequences of such non-adherence, interventions are lacking. Pocket Personal Assistant for Tracking Health (Pocket PATH) is a hand-held device developed for patients to record health data, review data trends, and report condition changes to the transplant team. Methods A pilot trial was conducted to compare self-care agency, self-care behaviors, and health-related quality of life (HRQOL) between recipients randomized to use Pocket PATH (n = 15) vs. standard care (n = 15) for the first two months following hospital discharge after lung transplantation. Results Baseline characteristics were equivalent across groups. Patients in the Pocket PATH group showed significantly higher ratings of self-care agency, performed self-care behaviors at significantly higher rates, and reported significantly better HRQOL than standard care controls. Conclusion Pocket PATH is more efficacious than standard care in promoting early self-care agency, self-care behaviors, and HRQOL in lung recipients. A large-scale randomized controlled trial is needed to test the impact of Pocket PATH on long-term self-care behaviors. PMID:19473201

    BACKGROUND In times of limited organs for transplantation, anti-HBc-positive organs can be accepted for lung transplantation to increase the number of donors. Transplant recipients should be vaccinated against hepatitis B to prevent HBV infection. However, response after HBV vaccination has only been poorly evaluated in patients with end-stage pulmonary disease. MATERIAL AND METHODS Anti-HBs titers of 40 anti-HBc negative patients with end-stage pulmonary disease evaluated for lung transplantation were analyzed with the Architect® system (Abbott, Germany). Responders, partial responders, or non-responders after HBV vaccination were defined by anti-HBs titers >100 IU/L, 10-100 IU/L, and <10 IU/L, respectively. RESULTS There were 34/40 individuals (85%) vaccinated against hepatitis B, and 6 were not vaccinated. Response, partial response, and non-response after vaccination were observed in 10/34 (29.4%), 11/34 (32.4%), and 13/34 (38.2%) of patients, respectively. Response to vaccination did not correlate with sex, pulmonary disease, comorbidities, immunosuppressive therapy, or smoking status. CONCLUSIONS Although 85% of patients evaluated for lung transplantation were vaccinated against hepatitis B, 38.2% did not show an anti-HBs titer >10 IU/L. Thus, anti-HBs titers should be regularly monitored. Nonresponders should be considered for booster vaccinations, alternative vaccination schedules, or prophylactic treatment with a nucleos(t)ide analogue in case of transplantation of an anti-HBc-positive organ.

    Obliterative bronchiolitis (OB) continues to be the major limitation to long-term survival after lung transplantation. The specific aetiology and pathogenesis of OB are not well understood. To explore the role of autoreactivity in OB, we spotted 751 different self molecules onto glass slides, and used these antigen microarrays to profile 48 human serum samples for immunoglobulin G (IgG) and IgM autoantibodies; 27 patients showed no or mild bronchiolitis obliterans syndrome (BOS; a clinical correlate of OB) and 15 patients showed medium to severe BOS. We now report that these BOS grades could be differentiated by a profile of autoantibodies binding to 28 proteins or their peptides. The informative autoantibody profile included down-regulation as well as up-regulation of both IgM and IgG specific reactivities. This profile was evaluated for robustness using a panel of six independent test patients. Analysis of the functions of the 28 informative self antigens showed that eight of them are connected in an interaction network involved in apoptosis and protein metabolism. Thus, a profile of autoantibodies may reflect pathological processes in the lung allograft, suggesting a role for autoimmunity in chronic rejection leading to OB. PMID:20201985

  6. Review of the International Society for Heart and Lung Transplantation Practice guidelines for management of heart failure in children.

    In 2004, practice guidelines for the management of heart failure in children by Rosenthal and colleagues were published in conjunction with the International Society for Heart and Lung Transplantation. These guidelines have not been updated or reviewed since that time. In general, there has been considerable controversy as to the utility and purpose of clinical practice guidelines, but there is general recognition that the relentless progress of medicine leads to the progressive irrelevance of clinical practice guidelines that do not undergo periodic review and updating. Paediatrics and paediatric cardiology, in particular, have had comparatively minimal participation in the clinical practice guidelines realm. As a result, most clinical practice guidelines either specifically exclude paediatrics from consideration, as has been the case for the guidelines related to cardiac failure in adults, or else involve clinical practice guidelines committees that include one or two paediatric cardiologists and produce guidelines that cannot reasonably be considered a consensus paediatric opinion. These circumstances raise a legitimate question as to whether the International Society for Heart and Lung Transplantation paediatric heart failure guidelines should be re-reviewed. The time, effort, and expense involved in producing clinical practice guidelines should be considered before recommending an update to the International Society for Heart and Lung Transplantation Paediatric Heart Failure guidelines. There are specific areas of rapid change in the evaluation and management of heart failure in children that are undoubtedly worthy of updating. These domains include areas such as use of serum and imaging biomarkers, wearable and implantable monitoring devices, and acute heart failure management and mechanical circulatory support.

    To determine whether density mapping (DM) is more accurate for detection and quantification of pathologic air trapping (pAT) in patients after lung transplantation compared to other CT air trapping measures. One-hundred forty-seven lung and heart-lung transplant recipients underwent CT-examinations at functional residual capacity (FRC) and total lung capacity (TLC) and PFT six months after lung transplantation. Quantification of air trapping was performed with the threshold-based method in expiration (EXP), density mapping (DM) and the expiratory to inspiratory ratio of the mean lung density (E/I-ratio MLD). A non-rigid registration of inspiration-expiration CT-data with a following voxel-to-voxel mapping was carried out for DM. Systematic variation of attenuation ranges was performed for EXP and DM and correlated with the ratio of residual volume to total lung capacity (RV/TLC) by Spearman rank correlation test. AT was considered pathologic if RV/TLC was above the 95th percentile of the predicted upper limit of normal values. Receiver operating characteristic (ROC) analysis was performed. The optimal attenuation range for the EXP method was from -790 HU to -950 HU (EXP(-790 to -950HU)) (r = 0.524, p<0.001) to detect air trapping. Within the segmented lung parenchyma, AT was best defined as voxel difference less than 80 HU between expiration and registered inspiration using the DM method. DM correlated best with RV/TLC (r = 0.663, p<0.001). DM and E/I-ratio MLD showed a larger AUC (0.78; 95% CI 0.69-0.86; 0.76, 95% CI 0.67-0.85) than EXP(-790 HU to -950 HU) (0.71, 95% CI 0.63-0.78). DM and E/I-ratio MLD showed better correlation with RV/TLC and are more suited quantitative CT-methods to detect pAT in lung transplant patients than the EXP(-790HU to -950HU).

    Breast metastases from non-mammary cancers are rare, especially when they appear synchronously. Clinically, it is vitally important to accurately diagnose these patients, as this will directly influence their treatment and survival. We present a very rare and complex case of bilateral breast adenocarcinomas with an EML4–ALK fusion, which was diagnosed as bilateral breast metastases of non-small-cell lung cancer by immunohistochemistry and comprehensive genomic investigation. The patient was successfully treated with an ALK inhibitor (crizotinib); symptoms improved quickly after initiation of crizotinib therapy, and a partial response was observed after 3 months. The experience of diagnosis and treatment of this case indicates the importance and necessity of genomic investigations in such patients, and suggests that we need to consider the rare possibility of this kind of metastasis in order to provide optimal treatment.

    Background The United States lung allocation score (LAS) allows rapid organ allocation to higher acuity patients. Although, waitlist time and waitlist mortality have improved, the costs of lung transplantation (LTx) in these higher acuity patients are largely unknown. We hypothesize that LTx in high LAS recipients is associated with increased charges and resource utilization. Methods and Materials Clinical and financial data for LTx patients at our institution in the post-LAS era (5/2005–2009) were reviewed with follow-up through 12/2009. Patients were stratified by LAS quartiles (Q). Total hospital charges for index admission and all admissions within 1yr of LTx were compared between Q4 versus the Q1–3 using Rank-Sum and Kruskal-Wallis tests, as charge data were not normally distributed. Results 84 LTx’s were performed during the study period. 63 (75%) survived 1yr; 10 (11.9%) died during the index admission. Median LAS was 37.5 (interquartile range (IQR) 34.3–44.8). LAS quartiles were: Q1,30.1–34.3, n=21; Q2,34.4–37.5, n=21; Q3,37.6–44.8, n=21; Q4,44.9–94.3, n=21. Charges for index admission were: Q4,$276,668 (IQR191,301–300,156) vs. Q1–3, $153,995(IQR 129,796–176,849), P<0.001. Index admission median length of stay was greater in Q4 (Q4:35d IQR 23–46 vs Q1–3:15d IQR11–22, P=0.003). For 1yr charges: Q4, $292,247 (IQR 229,192–421,597) vs. Q1–3, $188,342 (IQR 153,455–252,045), P=0.002. Index admission and 1yr charges in Q4 were higher than other quartiles when examined individually. Conclusions This is the first study to show increased charges in high LAS patients. Charges for the index admission and hospital care in the year post-LTx were higher in the highest LAS quartile compared to patients in the lowest 75% of LAS. PMID:20869886

    Isolated pulmonary involvement in pediatric Langerhans cell histiocytosis (LCH) is extremely rare. While the multisystem-LCH course varies from spontaneous remission to rapid deterioration with lethal outcome, single system involvement is generally associated with favorable prognosis. A child with isolated pulmonary LCH had an extremely rapid progression leading to respiratory failure, despite treatment with prednisone and vinblastine. Since lung hyperinflation and cystic degeneration contraindicated conventional mechanical ventilation, extracorporeal membrane oxygenation (ECMO) was chosen for 50 days as a bridge to lung transplantation. The mechanisms involved in disease progression and the usefulness of long-term ECMO are discussed. PMID:26840616

    Complement activation leads primarily to membrane attack complex formation and subsequent target cell lysis. Protection against self-damage is regulated by complement regulatory proteins, including CD46, CD55, and CD59. Within their promoter regions, single-nucleotide polymorphisms (SNPs) are present that could influence transcription. We analyzed these SNPs and investigated their influence on protein expression levels. A single SNP configuration in the promoter region of CD59 was found correlating with lower CD59 expression on lung endothelial cells (p = 0.016) and monocytes (p = 0.013). Lung endothelial cells with this SNP configuration secreted more profibrotic cytokine IL-6 (p = 0.047) and fibroblast growth factor β (p = 0.036) on exposure to sublytic complement activation than cells with the opposing configuration, whereas monocytes were more susceptible to antibody-mediated complement lysis (p < 0.0001). Analysis of 137 lung transplant donors indicated that this CD59 SNP configuration correlates with impaired long-term survival (p = 0.094) and a significantly higher incidence of bronchiolitis obliterans syndrome (p = 0.046) in the recipient. These findings support a role for complement in the pathogenesis of this posttransplant complication and are the first to show a deleterious association of a donor CD59 promoter polymorphism in lung transplantation.

    Among patients with respiratory insufficiency awaiting lung transplantation, small adult patients have a lower opportunity of receiving size-matched pulmonary grafts, because of the shortage of donors, particularly those of small size. Reducing the size of an oversized graft is one of the methods to increase the donor pool; similarly, ex vivo lung perfusion is an emerging technique aimed toward the same purpose. We describe how we combined the 2 techniques (lobar transplantation plus contralateral nonanatomic graft reduction during ex vivo lung perfusion) to overcome graft shortage in a clinical case. For the 1st time, this case report demonstrates that surgical manipulation during ex vivo lung perfusion does not affect the functional improvement in a lung previously judged to be not suitable for transplantation. The 6-month follow-up results are similar to those of standard bilateral lung transplantation.

    Immunosuppressive drugs used in the management of heart and lung transplants have a large monetary and quality of life cost due to their side effects. Total lymphoid irradiation (TLI) is one method of minimising the need for or replacing post-operative immunosuppressive drugs. A literature review was conducted on electronic databases using defined search terms. The aim was to establish the indications for the use of TLI, its advantages and disadvantages and the weaknesses associated with the methods used in related research. Eight articles were located that focused on TLI usage in combating organ rejection. These studies identified that the use of TLI resulted in a reduction in early rejection. One study reported a drop in rejection episodes from 0.46 to 0.14 episodes per patient per month once the TLI was complete. While the short-term prognosis is excellent, the long-term outlook is less positive with an increased risk of organ rejection and myelodysplasia 3.5 years post-TLI. This review reminds us that radiation therapy (RT) is not exclusively indicated for cancer treatment. While TLI cannot replace immunosuppressive drug therapy, it can offer a treatment option for people that cannot tolerate immunosuppressive drugs, or when conventional anti-rejection treatment is no longer viable. Reported long-term complications suggest that TLI should be used with caution. However, this modality should not be overlooked in cases of chronic rejection. Further research is required to establish the efficacy of RT in the treatment of transplant patients who are unsuitable for drug-based anti-rejection therapies. PMID:26229656

    Bacterial pneumonia and tracheobronchitis are diagnosed frequently following lung transplantation. The diseases share clinical signs of inflammation and are often difficult to differentiate based on culture results. Microbiome and host immune-response signatures that distinguish between pneumonia and tracheobronchitis are undefined. Using a retrospective study design, we selected 49 bronchoalveolar lavage fluid samples from 16 lung transplant recipients associated with pneumonia (n = 8), tracheobronchitis (n = 12) or colonization without respiratory infection (n = 29). We ensured an even distribution of Pseudomonas aeruginosa or Staphylococcus aureus culture-positive samples across the groups. Bayesian regression analysis identified non-culture-based signatures comprising 16S ribosomal RNA microbiome profiles, cytokine levels and clinical variables that characterized the three diagnoses. Relative to samples associated with colonization, those from pneumonia had significantly lower microbial diversity, decreased levels of several bacterial genera and prominent multifunctional cytokine responses. In contrast, tracheobronchitis was characterized by high microbial diversity and multifunctional cytokine responses that differed from those of pneumonia-colonization comparisons. The dissimilar microbiomes and cytokine responses underlying bacterial pneumonia and tracheobronchitis following lung transplantation suggest that the diseases result from different pathogenic processes. Microbiomes and cytokine responses had complementary features, suggesting that they are closely interconnected in the pathogenesis of both diseases. PMID:26693965

    Introduction. Bilateral vocal cord paralysis (BVCP) is a potential medical emergency. The Otolaryngologist plays a crucial role in the diagnosis and management of BVCP and must consider a broad differential diagnosis. We present a rare case of BVCP secondary to anti-Hu paraneoplastic syndrome. Case Presentation. A 58-year-old female presented to an Otolaryngology clinic with a history of progressive hoarseness and dysphagia. Flexible nasolaryngoscopy demonstrated BVCP. Cross-sectional imaging of the brain and vagus nerves was negative. An antiparaneoplastic antibody panel was positive for anti-Hu antibodies. This led to an endobronchial biopsy of a paratracheal lymph node, which confirmed the diagnosis of small cell lung cancer. Conclusion. Paraneoplastic neuropathy is a rare cause of BVCP and should be considered when more common pathologies are ruled out. This is the second reported case of BVCP as a presenting symptom of paraneoplastic syndrome secondary to small cell lung cancer. PMID:27668114

    Background The study objective was to compare the outcomes of intraoperative routine use of venoarterial (VA) extracorporeal membrane oxygenation (ECMO) versus selective use of cardiopulmonary bypass (CPB). Methods Between January 2010 and February 2013, 41 lung transplantations (LTx) were performed, and CPB was used as a primary cardiopulmonary support modality by selective basis (group A). Between March 2013 and December 2014, 41 LTx were performed, and ECMO was used routinely (group B). The two groups were compared retrospectively. Results The operative time was significantly longer in group A (group A, 458 min; group B, 420 min; P=0.041). Postoperatively, patients in group B had less fresh frozen plasma (FFP) transfusion (P=0.030). Complications were not different between the two groups. The 30- and 90-day survival rates were better in group B (30-day survival: group A, 75.6%; group B, 95.1%, P=0.012; 90-day survival: group A, 68.3%; group B, 87.8%, P=0.033). The 1-year survival showed better trends in group B, but it was not significant. Forced vital capacity (FVC) at 1, 3, and 6 months after LTx was better in group B than in group A (1 month: group A, 43.8%; group B, 52.9%, P=0.043; 3 months: group A, 45.5%; group B, 59.0%, P=0.005; 6 months: group A, 51.5%; group B, 65.2%, P=0.020). Forced expiratory volume in 1 second (FEV1) at 3 months after LTx was better in patients in group B than that in patient in group A (group A, 53.3%; group B, 67.5%, P=0.017). Conclusions Routine use of ECMO during LTx could improve early outcome and postoperative lung function without increased extracorporeal-related complication such as vascular and neurologic complications.

    Voriconazole is a triazole antifungal used to prevent and treat invasive fungal infections after lung transplantation, but it has been associated with an increased risk of developing cutaneous squamous cell carcinoma (SCC). Despite widespread use, there are no clear guidelines for optimal prophylactic regimens that balance the competing risks and benefits. We conducted a retrospective cohort study of all lung transplant recipients at the University of California, San Francisco, who were transplanted between October 1991 and December 2012 (n = 455) to investigate whether voriconazole exposure affected development of SCC, Aspergillus colonization, invasive aspergillosis and all-cause mortality. Voriconazole exposure was associated with a 73% increased risk of developing SCC (hazard ratio [HR] 1.73; 95% confidence interval [CI]: 1.04-2.88; p = 0.03), with each additional 30-day exposure at the standard dose increasing the risk by 3.0% (HR 1.03; 95% CI: 1.02-1.04; p < 0.001). Voriconazole exposure reduced risk of Aspergillus colonization by 50% (HR 0.50; 95% CI: 0.34-0.72; p < 0.001), but we were underpowered to detect risk reduction for invasive aspergillosis. Voriconazole exposure significantly reduced all-cause mortality among subjects who developed Aspergillus colonization (HR 0.34; 95% CI: 0.13-0.91; p = 0.03) but had no significant impact on those without colonization. Physicians should consider patient-specific factors that modify the potential risks and benefits of voriconazole for the care of lung transplant recipients. PMID:26372838

    Unconfounded comparative data on the type and dose of immunosuppressive agents among solid organ transplant recipients are sparse, as are data on longitudinal immunosuppressive therapy since transplantation. We addressed this issue in a population-based cohort of Australian liver (n = 1895), heart (n = 1220), and lung (n = 1059) transplant recipients, 1984-2006. Data on immunosuppressive therapy were retrospectively collected at discharge, three months, and one, five, 10, and 15 yr after first transplant. We computed unadjusted and adjusted estimates for the association between the type and dose of immunosuppressive therapy and organ type. After adjustment for confounders, use of induction antibody and maintenance corticosteroids was more common in heart and lung compared to liver recipients (p < 0.001), and antibody therapy for rejection more common in liver recipients (p < 0.001). Liver recipients were more likely to receive calcineurin inhibitor monotherapy, with or without corticosteroids, compared to heart and lung recipients (p < 0.001). Liver recipients consistently received lower doses of azathioprine than heart and lung recipients (p < 0.001). These differences in immunosuppression may partly explain variations in immunosuppression-related morbidity by transplanted organ, for example, malignancy risk. Longitudinal changes in the type and the dose of immunosuppressive therapy over time since transplantation also demonstrate the need for time-dependent data in observational research.

    This single-center study examines the incidence, etiology, and outcomes associated with prolonged mechanical ventilation (PMV), defined as time to definite spontaneous ventilation >21 days after double lung transplantation (LTx). A total of 690 LTx recipients between January 2005 and December 2012 were analyzed. PMV was necessary in 95 (13.8%) patients with decreasing incidence during the observation period (p < 0.001). Independent predictors of PMV were renal replacement therapy (odds ratio [OR] 11.13 [95% CI, 5.82-21.29], p < 0.001), anastomotic dehiscence (OR 8.74 [95% CI 2.42-31.58], p = 0.001), autoimmune comorbidity (OR 5.52 [95% CI 1.86-16.41], p = 0.002), and postoperative neurologic complications (OR 5.03 [95% CI 1.98-12.81], p = 0.001), among others. Overall 1-year survival was 86.0% (90.4% for LTx between 2010 and 2012); it was 60.7% after PMV and 90.0% in controls (p < 0.001). Conditional long-term outcome among hospital survivors, however, did not differ between the groups (p = 0.78). Multivariate analysis identified renal replacement therapy (hazard ratio [HR] 3.55 [95% CI 2.40-5.25], p < 0.001), post-LTx extracorporeal membrane oxygenation (HR 3.47 [95% CI 2.06-5.83], p < 0.001), and prolonged inotropic support (HR 1.95 [95% CI 1.39-2.75], p < 0.001), among others, as independent predictors of mortality. In conclusion, PMV complicated 14% of LTx procedures and, although associated with increased in-hospital mortality, outcomes among patients surviving to hospital discharge were unaffected.

    OBJECTIVE--To determine whether epoprostenol (prostacyclin, PGI2) or heart-lung transplantation (HLT), or both improves survival of patients with severe pulmonary hypertension. DESIGN--This was a prospective study where the effects of epoprostenol were compared with conventional treatment. Also, the benefits of epoprostenol and HLT were assessed by comparing survival in this group with that of 120 patients at the Mayo Clinic before HLT and epoprostenol treatment became available. PATIENTS AND INTERVENTIONS--Forty four patients were studied; 25 received continuous epoprostenol over a four year period (mean (SD) cardiac index 1.8 (0.4) 1 min-1 m-2 and mean (SD) pulmonary artery pressure (PAP) 70 (16) mm Hg) and 19 did not (cardiac index 2.1 (0.6) 1 min-1 m-2 and PAP 64 (13) mm Hg). Ten patients underwent HLT: seven had received epoprostenol, and three had not. RESULTS--The therapeutic intervention with epoprostenol, or HLT, or both improved survival compared with the Mayo clinic patients (p = 0.05). Most of the benefit was conferred by epoprostenol, which prolonged survival twofold from a median time of eight to 17 months and doubled the changes of successful HLT. The improved survival with epoprostenol was not related to its immediate capacity to cause pulmonary vasodilation. Those patients who had limited acute pulmonary vasodilation when treated with epoprostenol showed the greatest improvement in survival. CONCLUSIONS--These preliminary results indicate that those pulmonary hypertensive patients with the poorest chance of survival can be helped by epoprostenol and by HLT. PMID:8217447

    This article reports a case of perostitis deformans in a lung transplantation patient taking the fluoride-containing medication voriconazole, a relatively new and potent anti-fungal. The patient had a normal range of motion in all joints and a normal gait. On radiographs at presentation, multifocal areas of periostitis were visualized involving the left-hand first, second, and third proximal phalanx shafts. Similar periostitis was present on the left-hand third, fourth, and fifth middle phalanx shafts. Plain radiographs of the right hand also demonstrated multifocal periostitis of the third and fourth proximal and middle phalanges. Aggressive periostitis at the level of the right fourth proximal and middle phalanges was also present. Given her long-term treatment with voriconazole and a presentation consistent with periostitis deformans, voriconazole was presumed to be the offending agent and was replaced with itraconazole. The patient's symptoms resolved shortly after withdrawal of voriconazole.Voriconazole-associated periostitis has only recently been reported in the literature. Food and Drug Administration-approved in 2002, voriconazole is efficacious in treating serious, invasive fungal infections that are generally seen in immunocompromised patients. Due to the novel nature of voriconazole and the uncommon indications for its long-term use, the periostitis deformans described in this article may be unfamiliar to the orthopedic surgeon. Consequently, a patient presenting with bone pain and periosteal involvement on plain radiographs may provoke a broad, expensive, and ultimately unnecessary diagnostic evaluation. The clinical case and imaging findings presented here can help to promote understanding of this benign condition and its simple cure: voriconazole discontinuation.

    Abstract: Primary graft dysfunction (PGD) following lung transplantation is clinically similar to the acute respiratory distress syndrome. Because alcohol abuse independently increases the incidence of acute respiratory distress syndrome in at-risk individuals, we hypothesized that donor alcohol use is correlated with an increased risk of PGD. As a pilot study, we collected alcohol use histories using a validated instrument, the Alcohol Use Disorder Identification Test questionnaire, from 74 donors and correlated these with the development of PGD in corresponding recipients. Nineteen percent (14/74) of donors were classified as heavy alcohol users, as defined by the Alcohol Use Disorder Identification Test scores ≥8. In the 1st 4 days post-transplantation, similar percentages of recipients developed grade 3 PGD on at least 1 day (heavy alcohol user = 29% [4/14] versus lighter alcohol user = 27% [16/60]); however, recipients receiving a lung from a heavy alcohol user were more likely to have multiple and consecutive days of grade 3 PGD, especially in the 1st 48 hours post-transplant. Both median length of stay in the intensive care unit and hospital were somewhat longer in the heavy alcohol user group (9 versus 7 days and 19.5 versus 17.5 days, respectively). If these preliminary findings are validated in a multi-center study, they would have important implications not only for our understanding of the pathophysiology of PGD but also for the development of novel treatments based on the evolving evidence from experimental and clinical studies on how alcohol abuse renders the lung susceptible to acute edematous injury.

    Lung transplant recipients are at high risk of suffering many complications during the immediate postoperative period, such as primary graft dysfunction, acute graft rejection or infection. The most common symptom is the presence of acute respiratory failure, and the use of biomarkers could be useful for establishing an early diagnosis of these conditions. Different biomarkers have been studied, but none have proven to be the gold standard in the differential diagnosis of acute respiratory failure. This paper offers a review of the different biomarkers that have been studied in this field.

    It has been 5 years since our team reported the first successful model of orthotopic single lung transplantation in the mouse. There has been great demand for this technique due to the obvious experimental advantages the mouse offers over other large and small animal models of lung transplantation. These include the availability of mouse-specific reagents as well as knockout and transgenic technology. Our laboratory has utilized this mouse model to study both immunological and non-immunological mechanisms of lung transplant physiology while others have focused on models of chronic rejection. It is surprising that despite our initial publication in 2007 only few other laboratories have published data using this model. This is likely due to the technical complexity of the surgical technique and perioperative complications, which can limit recipient survival. As two of the authors (XL and WL) have a combined experience of over 2500 left and right single lung transplants, this review will summarize their experience and delineate tips and tricks necessary for successful transplantation. We will also describe technical advances made since the original description of the model. PMID:22754663

Besides its usefulness in the study of lymph nodes, transbronchial needle aspiration increases the overall performance of bronchoscopy by 20%, which means that it should be considered as a basic tool in the study of lung cancer. We also comment on the work by Galvis-Caravajal et al, who describe percutaneous radiofrequency as an alternative to radiotherapy in small lung or metastasic tumours. In diffuse interstitial disease, Morell et al analysed the diagnostic methods in 500 patients with this clinical-radiological presentation in which a definitive diagnosis was achieved in 85%, with 25% of them being obtained by non-invasively.

    Background In lung transplantation (LTx), patients with thoracic muscle sarcopenia may have to require longer to recovery. We measured thoracic muscle volume by using the cross sectional area (CSA) and assessed its effect on early outcomes after LTx. Methods A retrospective analysis was conducted to evaluate the effect of thoracic sarcopenia in patients undergoing LTx between January 2010 and July 2015. The lowest CSA quartile (Q1) was defined as sarcopenia. Results In total, 109 patients were enrolled. The mean CSA was 58.24±15.82 cm2. Patients in the highest CSA quartile were more likely to be male (92.6% vs. 17.9%, P<0.001), older (55.2±10.1 vs. 43.2±14.9 years, P=0.001), to have a higher body mass index (BMI) (22.3±4.0 vs. 19.4±3.7 kg/m2, P=0.007), and to have pulmonary fibrosis (85.2% vs. 35.7%, P=0.003) compared with the lowest CSA quartile. Early outcomes including ventilator support duration [32.9±49.2 vs. 24.5±39.9 days, P= not significant (ns)], intensive care unit (ICU) stay duration (28.4±43.7 vs. 24.4±35.9 days, P= ns) and hospital stay duration (61.4±48.2 vs. 50.8±37.2 days, P= ns) tended to be longer in Q1 than Q4, but the difference was not significant. However, the 1-year survival rate was better in Q1 compared with Q4 (66.6% vs. 46.0%, P=0.04). Conclusions Although patients with thoracic sarcopenia seem to require a longer post-operative recovery time after LTx, this does not compromise their early outcomes. By contrast, patients with larger thoracic muscle volume (Q4) showed poorer survival times. PMID:27621854

    Self-care behaviors are crucial for following the complex regimen after lung transplantation, yet little is known about recipients’ levels of self-care agency (the capability and willingness to engage in self-care behaviors) and its correlates. We examined levels of self-care agency and recipient characteristics (socio-demographics, psychological distress, quality of relationship with primary lay caregiver, and health locus of control) in 111 recipients. Based on Perceived Self-Care Agency scores, recipients were assigned to either the low or high self-care agency comparison group. Characteristics were compared between groups to identify characteristics likely to be associated with lower self-care agency. Mean (S.D.) score for self-care agency (scale range 53–265) was 223.02 (22.46). Recipients with lowest self-care agency scores reported significantly poorer quality of caregiver relationships (p < .001) and greater psychological distress (p < .001). After controlling for psychological distress, the quality of the recipient-caregiver relationship remained significantly associated with self-care agency. Every one-point decrease in the quality of caregiver relationship increased the risk of low self-care agency by 12%. Recipients with poorer caregiver relationships and greater psychological distress may need additional support to perform the self-care behaviors expected after lung transplantation. PMID:23004565

    Bronchiolitis obliterans syndrome (BOS) is the limiting factor to long-term survival after lung transplantation. Previous studies suggested respiratory viral tract infections are associated with the development of BOS. To identify the impact of virus detection in bronchoalveolar lavage (BAL) fluid, we analyzed BAL samples from 87 consecutive lung transplant recipients for human herpesvirus (HHV)-6, Epstein-Barr virus, Herpes simplex virus 1/2, Cytomegalovirus, respiratory syncytical virus and adenovirus by PCR. Acute rejection, BOS and death were recorded for a mean follow-up time of 3.27 +/- 0.47 years. Results of PCR analysis and other potential risk factors were entered into a Cox regression analysis of BOS predictors and death. Only acute rejection was a distinct risk factor for BOS of all stages, death and death from BOS. HHV-6 was detected in 20 patients. Univariate and multivariate analysis revealed that HHV-6 was associated with an increased risk to develop BOS > orb = stage 1 and death, separate from the risk attributable to acute rejection. Identification of HHV-6 DNA in BAL fluid is a potential risk factor for BOS. Our results warrant further studies to elucidate a possible causal link between HHV-6 and BOS. PMID:16303014

    Our goal was to assess the CT findings of cytomegalovirus (CMV) pneumonia in transplant patients. The study included 10 transplant patients who had chest CT scan and pathologically proven isolated pulmonary CMV infection. Five patients had bone marrow transplant and five had solid organ transplant. The CT scans were retrospectively reviewed for pattern and distribution of disease and the CT findings compared with the findings on open lung biopsy (n = 9) and autopsy (n = 1). Nine of 10 patients had parenchymal abnormalities apparent at CT and I had normal CT scans. The findings in the nine patients included small nodules (n = 6), consolidation (n = 4), ground-glass attenuation (n = 4), and irregular lines (n = 1). The nodules had a bilateral and symmetric distribution and involved all lung zones. The consolidation was most marked in the lower lung zones. The CT findings of CMV pneumonia in transplant patients are heterogeneous. The most common patterns include small nodules and areas of consolidation. 13 refs., 4 figs., 1 tab.

    Cellular transplantation strategies utilizing intraspinal injection of mesenchymal progenitor cells (MPCs) have been reported as beneficial for spinal cord injuries. However, intraspinal injection is not only technically challenging, but requires invasive surgical procedures for patients. Therefore, we investigated the feasibility and potential benefits of noninvasive intravenous injection of MPCs in two models of cervical spinal cord injury, unilateral C5 contusion and complete unilateral C5 hemisection. MPCs isolated from green fluorescence protein (GFP)-luciferase transgenic mice compact bone (1 × 10(6) cells), or vehicle Hank's Buffered Saline Solution (HBSS), were intravenously injected via the tail vein at D1, D3, D7, D10, or D14. Transplanted MPCs were tracked via bioluminescence imaging. Live in vivo imaging data showed that intravenously injected MPCs accumulate in the lungs, confirmed by postmortem bioluminescence signal-irrespective of the time of injection or injury model. The results showed a rapid, positive modulation of the inflammatory response providing protection to the injured spinal cord tissue. Histological processing of the lungs showed GFP(+) cells evenly distributed around the alveoli. We propose that injected cells can act as cellular target decoys to an immune system primed by injury, thereby lessening the inflammatory response at the injury site. We also propose that intravenous injected MPCs modulate the immune system via the lungs through secreted immune mediators or contact interaction with peripheral organs. In conclusion, the timing of intravenous injection of MPCs is key to the success for improving function and tissue preservation following cervical spinal cord injury. Stem Cells 2016;34:1812-1825.

  4. Endogenous and exogenous stem cells: a role in lung repair and use in airway tissue engineering and transplantation

    PubMed Central

    2010-01-01

    Rapid repair of the denuded alveolar surface after injury is a key to survival. The respiratory tract contains several sources of endogenous adult stem cells residing within the basal layer of the upper airways, within or near pulmonary neuroendocrine cell rests, at the bronchoalveolar junction, and within the alveolar epithelial surface, which contribute to the repair of the airway wall. Bone marrow-derived adult mesenchymal stem cells circulating in blood are also involved in tracheal regeneration. However, an organism is frequently incapable of repairing serious damage and defects of the respiratory tract resulting from acute trauma, lung cancers, and chronic pulmonary and airway diseases. Therefore, replacement of the tracheal tissue should be urgently considered. The shortage of donor trachea remains a major obstacle in tracheal transplantation. However, implementation of tissue engineering and stem cell therapy-based approaches helps to successfully solve this problem. To date, huge progress has been achieved in tracheal bioengineering. Several sources of stem cells have been used for transplantation and airway reconstitution in animal models with experimentally induced tracheal defects. Most tracheal tissue engineering approaches use biodegradable three-dimensional scaffolds, which are important for neotracheal formation by promoting cell attachment, cell redifferentiation, and production of the extracellular matrix. The advances in tracheal bioengineering recently resulted in successful transplantation of the world's first bioengineered trachea. Current trends in tracheal transplantation include the use of autologous cells, development of bioactive cell-free scaffolds capable of supporting activation and differentiation of host stem cells on the site of injury, with a future perspective of using human native sites as micro-niche for potentiation of the human body's site-specific response by sequential adding, boosting, permissive, and recruitment impulses

  5. Regulation of transplanted mesenchymal stem cells by the lung progenitor niche in rats with chronic obstructive pulmonary disease

    PubMed Central

    2014-01-01

    Background Stem cell transplantation is a promising method for the treatment of chronic obstructive pulmonary disease (COPD), and mesenchymal stem cells (MSCs) have clinical potential for lung repair/regeneration. However, the rates of engraftment and differentiation are generally low following MSC therapy for lung injury. In previous studies, we constructed a pulmonary surfactant-associated protein A (SPA) suicide gene system, rAAV-SPA-TK, which induced apoptosis in alveolar epithelial type II (AT II) cells and vacated the AT II cell niche. We hypothesized that this system would increase the rates of MSC engraftment and repair in COPD rats. Methods The MSC engraftment rate and morphometric changes in lung tissue in vivo were investigated by in situ hybridization, hematoxylin and eosin staining, Masson’s trichrome staining, immunohistochemistry, and real-time PCR. The expression of hypoxia inducible factor (HIF-1α) and stromal cell-derived factor-1 (SDF-1), and relationship between HIF-1α and SDF-1 in a hypoxic cell model were analyzed by real-time PCR, western blotting, and enzyme-linked immunosorbent assay. Results rAAV-SPA-TK transfection increased the recruitment of MSCs but induced pulmonary fibrosis in COPD rats. HIF-1α and SDF-1 expression were enhanced after rAAV-SPA-TK transfection. Hypoxia increased the expression of HIF-1α and SDF-1 in the hypoxic cell model, and SDF-1 expression was augmented by HIF-1α under hypoxic conditions. Conclusions Vacant AT II cell niches increase the homing and recruitment of MSCs to the lung in COPD rats. MSCs play an important role in lung repair and promote collagen fiber deposition after induction of secondary damage in AT II cells by rAAV-SPA-TK, which involves HIF-1α and SDF-1 signaling.

    The purpose of this endeavor is to compare the morbidity, mortality and costs of LVRS versus transplantation in severe emphysema. This was a retrospective review of severe emphysema patients who received LVRS (n = 70) from 1994-1999, or transplant (n = 87) from 1994-2004. Change in functional status was calculated by the change in modified BODE (mBODE) score. Financial data included physician, hospital and medication costs. Preoperatively, there was no significant difference between the transplant and LVRS groups (mean +/- SD) in age (57.7 +/- 5.7 vs. 59.1 +/- 8.3 years), BMI, Borg dyspnea score, 6-minute walk distance or mBODE (10.4 +/- 2.6 vs. 9.6 +/- 2.7, p = 0.4). Preoperatively, FEV1% (23.6 +/- 8.5 vs. 31.9 +/- 17.7, p = 0.008) was significantly lower in the transplant group. One year post-operatively, transplantation patients had a significantly greater improvement in mBODE (-5.7 vs. -2.0, p = 0.0004), FEV1% (43.4 vs. 2.2%, p = 0.0004) and Borg score (-3.0 vs. -1.4, p = 0.04). Transplantation patients had lower long-term survival compared to LVRS patients (p = 0.01). The only variable that affected survival was type of surgery favoring LVRS (hazard ratio 1.7, 95% confidence limits 1.05-2.77). During a mean follow-up of 2.4 +/- 2.5 years after transplant and 5.0 +/- 3.1 years after LVRS, transplantation mean total costs were greater ($381,732 vs. $140,637, p < 0.0001). Transplantation patients spent more time in the hospital (74.3 +/- 81.3 vs. 39.5 +/- 66.7 days, p = 0.009) and had more outpatient visits (29.9 +/- 28.8 vs. 12.3 +/- 12.6 visits, p < 0.0001). In patients who survive over 1 year, transplantation provides a higher level of functional status and a greater improvement in airflow obstruction, dyspnea, exercise tolerance, and mBODE score, but costs more and carries greater mortality.

    We evaluated the diagnostic value of high-resolution computed tomography (HRCT) images generated from 64 detector multi-slice CT scanners (HRCT(64-MSCT) imaging) in relation to primary graft dysfunction (PGD) after lung-transplantation (LUTX) in a pilot study. PGD has mortality rates ranging from 17 to 50% over a 90-day period. Detailed HRCT lung images, reconstructed using 64-MSCT, may aid diagnostic and therapeutic efforts in PGD. Thirty-two patients were scanned four times within a year post-LUTX, in a single-centre prospective study. HRCT lung images were reviewed, evaluated and scored by two observers, for ground-glass (GG) opacities, consolidation, septal thickening (ST) and pulmonary embolism. Image and PGD scores were compared in each patient. GG and consolidation changes were largely present up until 2 weeks post-LUTX, and markedly reduced by the 12th week. ST was predominantly found in patients with PGD. There were no vascular changes found at CT angiographies. The most severe cases of GG opacities and consolidation were found in patients with PGD. ST seems to be an important indicator of PGD. HRCT(64-MSCT) imaging may be a useful tool for the identification of pathological features of PGD not detected by classical evaluation in patients undergoing LUTX. PMID:22378316

    Hematopoietic stem cell transplantation (HSCT) efficacy is limited by numerous pulmonary complications. We developed a model of syngeneic bone marrow transplantion (BMT) followed by infection with murine gamma herpesvirus-68 that results in pneumonitis and fibrosis and mimics human "noninfectious" HSCT complications. BMT mice experience increased early lytic replication, but establish viral latency by 21 days post infection. CD4 T cells in BMT mice are skewed toward interleukin (IL)-17A rather than interferon (IFN)-γ production. Transplantation of bone marrow from Il-17a(-/-) donors or treatment with anti-IL-17A neutralization antibodies at late stages attenuates pneumonitis and fibrosis in infected BMT mice, suggesting that hematopoietic-derived IL-17A is essential for development of pathology. IL-17A directly influences activation and extracellular matrix production by lung mesenchymal cells. Lung CD11c+ cells of BMT mice secrete more transforming growth factor beta-β1, and pro-TH17 mRNAs for IL-23 and IL-6, and less TH1-promoting cytokine mRNA for IFN-γ but slightly more IL-12 mRNA in response to viral infection. Adoptive transfer of non-BMT lung CD11c-enriched cells restores robust TH1 response and suppresses aberrant TH17 response in BMT mice to improve lung pathology. Our data suggest that "noninfectious" HSCT lung complications may reflect preceding viral infections and demonstrate that IL-17A neutralization may offer therapeutic advantage even after disease onset.

    A 38-year-old patient with systemic lupus erythematosus presented with pulmonary infiltrates and hypoxemia for several months following immunodepleting autologous hematopoietic stem cell transplantation. She was treated for influenza, which was isolated repeatedly from ororpharynx and bronchoalveolar lavage fluids, and later empirically for lupus pneumonitis, but expired 6 months after transplant. Autopsy findings failed to show influenza in the lungs or lupus pneumonitis. A novel generic PCR-based assay using degenerate primers identified human coronavirus HKU1 RNA in bronchoalveolar lavage fluid at autopsy. Coronavirus was confirmed by virus-specific PCRs of lung tissue at autopsy. Electron microscopy showed viral particles consistent with coronavirus HKU1 in lung tissue both at autopsy and from a previous biopsy. While human coronavirus HKU1 infection is not usually severe, in highly immunocompromised patients, it can be associated with fatal pneumonia. PMID:21749586

    Rationale Patients with chronic liver disease are at an increased risk of developing transfusion-associated acute lung injury (TRALI) from plasma containing blood products. Similarly, red blood cell transfusions have been associated with post-operative and nosocomial infections in surgical and critical care populations. Patients undergoing liver transplantation receive a large amount of cellular and plasma containing blood products, but it is presently unclear which blood components are associated with these post-operative complications. Results A retrospective cohort study of 525 consecutive liver transplant patients revealed a peri-operative TRALI incidence of 1.3% (7/525), 95%CI [0.6%–2.7%], associated with an increased hospital mortality (28.6% (2/7) vs. 2.9% (15/518), p=0.02) and intensive care unit (ICU) length of stay (2 days, [1–11] vs. 0 days [0–2], 0.03). Only high plasma containing blood products (plasma and platelets) were associated with the development of TRALI. A total of 14.3% (74/525) of patients developed a post-operative infection which was also associated with an increased in-hospital mortality (10.8% (8/74) vs. 2.0% (9/451), p < 0.01) and prolonged length of stay. Multivariate logistic regression identified the number of red blood cell units transfused (adj OR 1.08 95%CI [1.02–1.14], p<0.01), the presence of peri-operative renal dysfunction and re-operation to be significantly associated with post-operative infection. Conclusions Patients undergoing liver transplantation are at high risk of developing post-operative complications from blood transfusion. Plasma containing blood products were associated with the development of TRALI while red blood cells were associated with the development of post-operative infection in a dose dependent manner.

    There is a need to develop three-dimensional structures that mimic the natural islet tissue microenvironment. Endocrine micro-pancreata (EMPs) made up of acellular organ-derived micro-scaffolds seeded with human islets have been shown to express high levels of key beta-cell specific genes and secrete quantities of insulin per cell similar to freshly isolated human islets in a glucose-regulated manner for more than three months in vitro. The aim of this study was to investigate the capacity of EMPs to restore euglycemia in vivo after transplantation of mouse or human islets in chemically diabetic mice. We proposed that the organ-derived EMPs would restore the extracellular components of the islet microenvironment, generating favorable conditions for islet function and survival. EMPs seeded with 500 mouse islets were implanted intraperitoneally into streptozotocin-induced diabetic mice and reverted diabetes in 67% of mice compared to 13% of controls (p = 0.018, n = 9 per group). Histological analysis of the explanted grafts 60 days post-transplantation stained positive for insulin and exhibited increased vascular density in a collagen-rich background. EMPs were also seeded with human islets and transplanted into the peritoneal cavity of immune-deficient diabetic mice at 250 islet equivalents (IEQ), 500 IEQ and 1000 IEQ. Escalating islet dose increased rates of normoglycemia (50% of the 500 IEQ group and 75% of the 1000 IEQ group, n = 3 per group). Human c-peptide levels were detected 90 days post-transplantation in a dose-response relationship. Herein, we report reversal of diabetes in mice by intraperitoneal transplantation of human islet seeded on EMPs with a human islet dose as low as 500 IEQ. PMID:27227978

    Background Ex-vivo lung perfusion (EVLP) is a novel technique to assess, and potentially repair marginal lungs that may otherwise be rejected for transplantation. Adenosine has been shown to protect against lung ischemia-reperfusion injury through its A2A receptor. We hypothesized that combining EVLP with adenosine A2A receptor agonist treatment would enhance lung functional quality and increase donor lung usage. Methods Eight bilateral pig lungs were harvested and flushed with cold Perfadex. After 14 hours storage at 4°C, EVLP was performed for 5 hours on two explanted lung groups: 1) Control group lungs (n=4), were perfused with Steen Solution and Dimethyl sulfoxide (DMSO), and 2) treated group lungs (n=4) received 10μM CGS21680, a selective A2A receptor agonist, in a Steen Solution-primed circuit. Lung histology, tissue cytokines, gas analysis and pulmonary function were compared between groups. Results Treated lungs demonstrated significantly less edema as reflected by wet-dry weight ratio (6.6 vs. 5.2, p<0.03) and confirmed by histology. In addition, treated lung demonstrated significantly lower levels of interferon gamma (45.1 vs. 88.5, p<0.05). Other measured tissue cytokines (interleukin (IL) 1 beta, IL-6, and IL-8) were lower in treatment group, but values failed to reach statistical significance. Oxygenation index was improved in the treated group (1.5 vs. 2.3, p<0.01) as well as mean airway pressure (10.3 vs. 13 p<0.009). Conclusions EVLP is a novel and efficient way to assess and optimize lung function and oxygen exchange within donor lungs, and the use of adenosine A2A agonist potentiates its potential. EVLP with the concomitant administration of A2A agonist may enhance donor lung quality and could increase the donor lung pool for transplantation. PMID:22051279

    Noninfectious lung injury and acute graft-versus-host disease (GVHD) after allogeneic hematopoietic cell transplantation (allo-HCT) are associated with significant morbidity and mortality. Azithromycin is widely used in allogeneic HCT recipients for pulmonary chronic GVHD, although current data appear controversial. We induced GVHD and noninfectious lung injury in lethally irradiated B6D2F1 mice by transplanting bone marrow and splenic T cells from allogeneic C57BL/6 mice. Experimental groups were treated with oral azithromycin starting on day 14 until the end of week 6 or week 14 after transplantation. Azithromycin treatment resulted in improved survival and decreased lung injury; the latter characterized by improved pulmonary function, reduced peribronchial and perivascular inflammatory cell infiltrates along with diminished collagen deposition, and a decrease in lung cytokine and chemokine expression. Azithromycin also improved intestinal GVHD but did not affect liver GVHD at week 6 early after transplantation. At week 14, azithromycin decreased liver GVHD but had no effect on intestinal GVHD. In vitro, allogeneic antigen-presenting cell (APC)- dependent T cell proliferation and cytokine production were suppressed by azithromycin and inversely correlated with relative regulatory T cell (Treg) expansion, whereas no effect was seen when T cell proliferation occurred APC independently through CD3/CD28-stimulation. Further, azithromycin reduced alloreactive T cell expansion but increased Treg expansion in vivo with corresponding downregulation of MHC II on CD11c(+) dendritic cells. These results demonstrate that preventive administration of azithromycin can reduce the severity of acute GVHD and noninfectious lung injury after allo-HCT, supporting further investigation in clinical trials.

    Background: The factors affecting the outcome of patients referred for lung transplantation (LTx) still have not been investigated extensively. The aim of this study was to characterize the patient outcomes and identify the prognostic factors for death while awaiting the LTx. Methods: From January 2003 to November 2013, the clinical data of 103 patients with end-stage lung disease that had been referred for LTx to Department of Thoracic Surgery, Shanghai Pulmonary Hospital were analyzed retrospectively. The relationship between predictors and survival was evaluated using the Kaplan–Meier method and the Cox proportional hazards model. Results: Twenty-five patients (24.3%) died while awaiting the LTx. Fifty patients (48.5%) underwent LTx, and 28 patients (27.2%) were still on the waitlist. Compared to the candidates with chronic obstructive pulmonary disease (COPD), patients with idiopathic pulmonary fibrosis (IPF) had a higher mortality while awaiting the LTx (40.0% vs. 12.3%, P = 0.003). Patients requiring mechanical ventilation (MV) had a higher mortality while waiting than others (50.0% vs. 20.2%, P = 0.038). Two variables, using MV and IPF but not COPD as primary disease, emerged as significant independent risk factors for death on the waitlist (hazard ratio [HR] = 56.048, 95% confidence interval [CI]: 3.935–798.263, P = 0.003 and HR = 14.859, 95% CI: 2.695–81.932, P = 0.002, respectively). Conclusion: The type of end-stage lung disease, pulmonary hypertension, and MV may be distinctive prognostic factors for death while awaiting the LTx. PMID:26712425

    Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer that is associated with a poor prognosis and for which no targeted therapies currently exist. In order to improve preclinical testing for TNBC that relies primarily on using human xenografts in immunodeficient mice, we have developed a novel immunocompetent syngeneic murine tumor transplant model for basal-like triple-negative breast cancer. The C3(1)/SV40-T/t-antigen (C3(1)/Tag) mouse mammary tumor model in the FVB/N background shares important similarities with human basal-like TNBC. However, these tumors or derived cell lines are rejected when transplanted into wt FVB/N mice, likely due to the expression of SV40 T-antigen. We have developed a sub-line of mice (designated REAR mice) that carry only one copy of the C3(1)/Tag-antigen transgene resulting from a spontaneous transgene rearrangement in the original founder line. Unlike the original C3(1)/Tag mice, REAR mice do not develop mammary tumors or other phenotypes observed in the original C3(1)/Tag transgenic mice. REAR mice are more immunologically tolerant to SV40 T-antigen driven tumors and cell lines in an FVB/N background (including prostate tumors from TRAMP mice), but are otherwise immunologically intact. This transplant model system offers the ability to synchronously implant the C3(1)/Tag tumor-derived M6 cell line or individual C3(1)/Tag tumors from various stages of tumor development into the mammary fat pads or tail veins of REAR mice. C3(1)/Tag tumors or M6 cells implanted into the mammary fat pads spontaneously metastasize at a high frequency to the lung and liver. M6 cells injected by tail vein can form brain metastases. We demonstrate that irradiated M6 tumor cells or the same cells expressing GM-CSF can act as a vaccine to retard tumor growth of implanted tumor cells in the REAR model. Preclinical studies performed in animals with an intact immune system should more authentically replicate treatment responses in

    2013-01-01

    Background Adipose-derived stromal cells (ADSCs) are a good alternative to multipotent stem cells for regenerative medicine. Low tidal volume (LVT) has proved to be an effective ventilation strategy. However, it is not known if ADSCs and LVT can protect against ventilator-induced lung injury (VILI). This study was aimed to determine the potential of ADSCs and LVT to repair following VILI and to elucidate the mechanisms responsible for this section. Methods A total of 72 rats were randomly assigned into group I (sham group, n = 18), group II (1 h of high tidal volume-ventilated (HVT) 40 mL/kg to peak airway pressures of approximately 35 cm H2O and 100% oxygen, n = 18), group III (1 h of HVT followed by 6 h LVT 6 mL/kg to peak airway pressures of approximately 6 cm H2O and 100% oxygen, n = 18) and group IV (1 h of HVT followed by intravenous injection of 5 × 106 ADSCs, n = 18). All animals were sacrificed 7 after the experiments lasted for 7 hours. Bronchoalveolar lavage fluid (BALF) was collected and lungs were harvested for analysis. Results High tidal volume-ventilated (HVT) rats exhibited typical VILI features compared with sham rats. Lung edema, histological lung injury index, concentrations of total protein, total cell counts, number of neutrophils in bronchoalveolar lavage fluid (BALF), tumor necrosis factor-α, interleukin (IL)-1β, IL-6, IL-10 and transforming growth factor-β1 in BALF were significantly increased in HVT rats. Additionally, gene and protein levels of Na+ channel subunits, Na-K-ATPase pump activity and alveolar fluid clearance were significantly decreased in HVT rats. All these indices of VILI were significantly improved in rats treated with ADSCs. However, compared with ADSCs treatment, LVT strategy had little therapeutic effect in the present study. Conclusion These results may provide valuable insights into the effects of ADSCs in acute lung injury. PMID:23890086

    The aim of this study was to assess the outcome and tolerability of prophylactic nebulized liposomal amphotericin B (n-LAB) in lung transplant recipients (LTR) and the changing epidemiology of Aspergillus spp. infection and colonization. We performed an observational study including consecutive LTR recipients (2003-2013) undergoing n-LAB prophylaxis lifetime. A total of 412 patients were included (mean postoperative follow-up 2.56 years; IQR 1.01-4.65). Fifty-three (12.8%) patients developed 59 Aspergillus spp. infections, and 22 invasive aspergillosis (overall incidence 5.3%). Since 2009, person-time incidence rates of Aspergillus spp. colonization and infection decreased (2003-2008, 0.19; 2009-2014, 0.09; P = 0.0007), but species with reduced susceptibility or resistance to amphotericin significantly increased (2003-2008, 38.1% vs 2009-2014, 58.1%; P = 0.039). Chronic lung allograft dysfunction (CLAD) was associated with Aspergillus spp. colonization and infection (HR 24.4, 95% CI 14.28-41.97; P = 0.00). Only 2.9% of patients presented adverse effects, and 1.7% required discontinuation. Long-term administration of prophylaxis with n-LAB has proved to be tolerable and can be used for preventing Aspergillus spp. infection in LTR. Over the last years, the incidence of Aspergillus spp. colonization and infection has decreased, but species with reduced amphotericin susceptibility or resistance are emerging. CLAD is associated with Aspergillus spp. colonization and infection.

    Hematopoietic stem cell transplantation (HSCT) efficacy is limited by numerous pulmonary complications. We developed a model of syngeneic bone marrow transplant (BMT) followed by infection with murine gamma herpesvirus (γHV-68) that results in pneumonitis and fibrosis and mimics human “non-infectious” HSCT complications. BMT mice experience increased early lytic replication, but establish viral latency by 21 days post infection (dpi). CD4 T cells in BMT mice are skewed towards IL-17A rather than IFN-γ production. Transplantation of bone marrow from Il-17a−/− donors or treatment with anti-IL-17A neutralization antibodies at late stages attenuates pneumonitis and fibrosis in infected BMT mice, suggesting that hematopoietic-derived IL-17A is essential for development of pathology. IL-17A directly influences activation and extracellular matrix production by lung mesenchymal cells. Lung CD11c+ cells of BMT mice secrete more TGF-β1, and pro-TH17 mRNAs for IL-23 and IL-6, and less TH1-promoting cytokine mRNA for IFN-γ but slightly more IL-12 mRNA in response to viral infection. Adoptive transfer of non-BMT lung CD11c-enriched cells restores robust TH1 response and suppresses aberrant TH17 response in BMT mice to improve lung pathology. Our data suggest “non-infectious” HSCT lung complications may reflect preceding viral infections and demonstrate that IL-17A neutralization may offer therapeutic advantage even after disease onset.

    Chest fat estimation is important for identifying high-risk lung transplant candidates. In this paper, an approach to chest fat quantification based on a recently formulated concept of standardized anatomic space (SAS) is presented. The goal of this paper is to seek answers to the following questions related to chest fat quantification on single slice versus whole volume CT, which have not been addressed in the literature. What level of correlation exists between total chest fat volume and fat areas measured on single abdominal and thigh slices? What is the anatomic location in the chest where maximal correlation of fat area with fat volume can be expected? Do the components of subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) have the same area-to-volume correlative behavior or do they differ? The SAS approach includes two steps: calibration followed by transformation which will map the patient slice locations non-linearly to SAS. The optimal slice locations found for SAT and VAT based on SAS are different and at the mid-level of the T8 vertebral body for SAT and mid-level of the T7 vertebral body for VAT. Fat volume and area on optimal slices for SAT and VAT are correlated with Pearson correlation coefficients of 0.97 and 0.86, respectively. The correlation of chest fat volume with abdominal and thigh fat areas is weak to modest.

    The present study aimed to investigate the impact of indomethacin treatment combined with oxaliplatin treatment on the expression of cluster of differentiation 44 variant 6 (CD44v6), matrix metalloproteinase-2 (MMP-2) and survivin in human lung cancer-nude mouse transplanted tumors. The human lung adenocarcinoma (A549)-nude mouse transplanted tumor model was established, and the mice were divided into a control group, an indomethacin treatment group, an oxaliplatin treatment group and an indomethacin-oxaliplatin combination treatment group. The tumor inhibition rate was calculated following sacrificing of the mice. Immunohistochemical staining and fluorescence reverse transcription-quantitative polymerase chain reaction were utilized to detect the protein and messenger (m)RNA expression of CD44v6, MMP-2 and survivin. The tumor inhibition rates of the indomethacin group, the oxaliplatin group and the combination group were 26.67, 47.70 and 68.88%, respectively. The protein and mRNA expression levels of CD44v6, MMP-2 and survivin in the transplanted tumors of each treatment group were reduced compared with the control group (P<0.05), and those of the combination group were lower compared with the single-drug treatment groups (P<0.05). Survivin and MMP-2, MMP-2 and CD44v6, and MMP-2 and CD44v6 all exhibited linear positive correlation. The present study provides evidence that the administration of indomethacin alone, or in combination with oxaliplatin, may significantly inhibit the growth of lung cancer-nude mouse transplanted tumors and the expression of CD44v6, MMP-2 and survivin inside the tumor. The combination of non-steroidal anti-inflammatory drugs with chemotherapeutic drugs may improve the antitumor effects. PMID:27313765

    This prospective interventional study investigated the impact of a three-month, ambulatory HA or HB, semi-individualized, PT-prescribed exercise program following pediatric HTx or LTx. SMW distance, strength, and flexibility were assessed at start and completion of the program and one yr after enrollment. Subjects received either an HB or HA exercise program three times per week. The cohort demonstrated clinically and statistically significant improvements in SMW distances at three months (425.7 ± 109.4-500.6 ± 93.6 m, p < 0.001) and at one yr (528.5 ± 66.6 m, p = 0.001), although there was no difference between the two groups at any time. Similar improvements were also observed in strength and flexibility measures. Correlates with higher SMW distance at three months and one yr included older age, male gender, and underlying diagnosis other than CHD. Male gender and diagnosis other than CHD were associated with a slower improvement in the SMW distance. This is the first report of institutionally based, outpatient exercise rehabilitation in the recovery following pediatric thoracic transplantation. We found similar improvements to HB interventions up to one yr after surgery. Further study of the role of exercise rehabilitation and long-term fitness outcomes is needed.

  3. Bilateral vestibulopathy.

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    Cardiothoracic transplantation's success at prolonging life--and its economic costs--must be considered relative to its psychosocial benefits and costs. Moreover, psychosocial outcomes themselves influence long-term post-transplant morbidity and mortality rates. Although psychosocial outcomes--encompassing patients' physical, psychologic and social functioning, their management of their medical regimen and global quality of life--are the focus of many recent studies, these investigations have yet to yield many evidence-based interventions that are routinely applied to improve patient outcomes. Our goals were to summarize existing work on psychosocial outcomes, delineate areas requiring attention, offer recommendations for steps to advance the field, and thereby provide an impetus for the conduct of clinical trials of interventions to improve these outcomes. We concluded that research must generally shift away from descriptive studies and toward prospective and clinical trial designs to: (a) examine a full range of risk factors and clinical sequelae of patients' psychosocial status; and (b) evaluate the effectiveness of psychosocial interventions. In addition, these issues must be considered across all cardiothoracic recipients, including not only heart recipients but the less-studied populations of lung and heart-lung recipients, and must include longer-term (5+ years) outcomes than is typical in most work. The importance of adequately sized samples to ensure statistical power, and the need to construct study samples representative of the larger cardiothoracic transplant population, cannot be overestimated. Implementing these changes in research design and substantive focus will ensure that psychosocial outcomes research will have maximum impact on transplant recipients' clinical care. PMID:16730578

    We examined the effect of alemtuzumab and basiliximab induction therapy on patient survival and freedom from bronchiolitis obliterans syndrome (BOS) in double lung transplantation. The United Network for Organ Sharing database was reviewed for adult double lung transplant recipients from 2006 to 2013. The primary outcome was risk-adjusted all-cause mortality. Secondary outcomes included time to BOS. There were 6117 patients were identified, of whom 738 received alemtuzumab, 2804 received basiliximab, and 2575 received no induction. Alemtuzumab recipients had higher lung allocation scores compared with basiliximab and no-induction recipients (41.4 versus 37.9 versus 40.7, p < 0.001) and were more likely to require mechanical ventilation before to transplantation (21.7% versus 6.5% versus 6.2%, p < 0.001). Median survival was longer for alemtuzumab and basiliximab recipients compared with patients who received no induction (2321 versus 2352 versus 1967 days, p = 0.001). Alemtuzumab (hazard ratio 0.80, 95% confidence interval 0.67-0.95, p = 0.009) and basiliximab induction (0.88, 0.80-0.98, p = 0.015) were independently associated with survival on multivariate analysis. At 5 years, alemtuzumab recipients had a lower incidence of BOS (22.7% versus 55.4 versus 55.9%), and its use was independently associated with lower risk of developing BOS on multivariate analysis. While both induction therapies were associated with improved survival, patients who received alemtuzumab had greater median freedom from BOS. PMID:26833657

    Molecular characterization of cyp51A from the azole-resistant Aspergillus fumigatus isolate 50593 from a lung transplant patient showed Y121F/T289A changes coupled with a 46-bp tandem repeat (TR46) on the promoter, whereas cyp51A from the pretherapy isolate, A. fumigatus 47381, showed no changes. This is the first reported case of A. fumigatus azole resistance due to Y121F/T289A/TR46 in the United States, suggesting that multiple mutational alterations of cyp51A resulting in high-level azole resistance could occur during prolonged antifungal therapy.

    The long-term success of lung transplantation continues to be challenged by the development of chronic lung allograft dysfunction (CLAD). The purpose of this study was to investigate the relationship between cytokine expression levels in pre-implanted donor lungs and the posttransplant development of CLAD and its subtypes, bronchiolitis obliterans syndrome (BOS) and restrictive allograft syndrome (RAS). Of 109 patients who underwent bilateral lung or heart-lung transplantation and survived for more than 3 months, 50 BOS, 21 RAS and 38 patients with No CLAD were identified by pulmonary function test results. Using donor lung tissue biopsies sampled from each patient, expression levels of IL-6, IL-1β, IL-8, IL-10, interferon-γ and tumor necrosis factor-α mRNA were measured. IL-6 expression levels were significantly higher in pre-implanted lungs of patients that ultimately developed BOS compared to RAS and No CLAD (p = 0.025 and 0.011, respectively). Cox regression analysis demonstrated an association between high IL-6 expression levels and BOS development (hazard ratio = 4.98; 95% confidence interval = 2.42-10.2, p < 0.001). In conclusion, high IL-6 mRNA expression levels in pre-implanted donor lungs were associated with the development of BOS, not RAS. This association further supports the contention that early graft injury impacts on both late graft function and early graft function. PMID:24164971

    Extracorporeal membrane oxygenation (ECMO) is used for refractory respiratory failure. Normally, ECMO is implanted in intubated patients as a last resort. We report the case of a non-intubated patient who benefited from veno-venous (VV) ECMO. A 35-year old cystic fibrosis man presented a severe respiratory decompensation with refractory hypercapnia. We opted for an ECMO instead of mechanical ventilation (MV). We implanted a double lumen bi-cava cannula (DLC) (Avalon Elite(TM)) in the right jugular vein. Before ECMO implantation, the patient presented refractory respiratory failure (pH = 7.1, PaO(2) = 83 mmHg, PaCO(2 )= 103 mmHg). We proposed that the patient be placed on the high emergency lung transplantation waiting list after failure to wean him from ECMO. This registration was effective 10 days after ECMO implantation. The patient was grafted the next day. Under ECMO, mean PaO(2), PaCO(2) and TCA were 80.6 ± 14.2, 53.8 ± 6.4 mmHg and 56.2 ± 9.7 s, respectively. The patient could eat, drink, talk and practice chest physiotherapy. The evolution was uneventful under ECMO. Weaning from ECMO was done in the operating theatre after transplantation. VV ECMO with DLC is safe and feasible in non-intubated patients. It avoids potential complications of MV, and allows respiratory assistance as bridge to transplantation. PMID:22108944

    Aim To retrospectively assess if the modified lung function score (LFS) and/or its components, forced expiratory volume within the first second (FEV1) and diffusion capacity for carbon monoxide corrected for hemoglobin level (cDLCO), predict overall survival (OS) and chronic graft-vs-host-disease (cGvHD). Methods We evaluated 241 patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT) at the University of Regensburg Transplant Center between June 1998 and July 2005 in relation to their LFS, FEV1 and cDLCO, before and after HSCT. Results Decreased OS after allo-HSCT was related to decreased pre-transplantation values of FEV1<60% (P = 0.040), cDLCO<50% of predicted value (P = 0.025), and LFS≥III (P = 0.037). It was also related to decreased FEV1 at 3 and 12 months after HSCT (P < 0.001 and P = 0.001, respectively) and increased LFS at 3 and 12 months after HSCT (P = 0.028 and P = 0.002, respectively), but not to changes of cDLCO. A higher incidence of cGvHD was related to decreased FEV1 at 6, 12, and 18 months (P = 0.069, P = 0.054, and P = 0.009, respectively) and increased LFS at 12 months (P = 0.002), but not to changes in cDLCO. Conclusions OS was related to both LFS and FEV1, but cGvHD had a stronger relation to FEV1 than to cDLCO or LFS. FEV1 alone offered more information on the outcome after allo-HSCT than LFS or cDLCO, suggesting limited value of LFS for the patients’ assessment after allo-HSCT. PMID:26935611

    Lung transplantation is an established life-saving therapy for patients with end-stage lung disease. Unfortunately, greater success in lung transplantation is hindered by a shortage of lung donors and the relatively poor early-, mid-, and long-term outcomes associated with severe primary graft dysfunction. Ex vivo lung perfusion has emerged as a modern preservation technique that allows for a more accurate lung assessment and improvement in lung quality. This review outlines the: (i) rationale behind the method; (ii) techniques and protocols; (iii) Toronto ex vivo lung perfusion method; (iv) devices available; and (v) clinical experience worldwide. We also highlight the potential of ex vivo lung perfusion in leading a new era of lung preservation. PMID:26700566

We have previously identified the development of antibodies (Abs) following lung transplantation to K-{alpha}1-tubulin (KAT), an epithelial surface gap junction cytoskeletal protein, in patients who develop BOS. However, the biochemical and molecular basis of the interactions and signaling cascades mediated by KAT Abs are yet to be defined. In this report, we investigated the biophysical basis of the epithelial cell membrane surface interaction between KAT and its specific Abs. Towards this, we analyzed the role of the lipid raft-domains in the membrane interactions which lead to cell signaling and ultimately increased growth factor expression. Normal human bronchial epithelial (NHBE) cells, upon specific ligation with Abs to KAT obtained either from the serum of BOS(+) patients or monoclonal KAT Abs, resulted in upregulation of growth factors VEGF, PDGF, and bFGF (6.4 {+-} 1.1-, 3.2 {+-} 0.9-, and 3.4 {+-} 1.1-fold increase, respectively) all of which are important in the pathogenesis of BOS. To define the role for lipid raft in augmenting surface interactions, we analyzed the changes in the growth factor expression pattern upon depletion and enrichment with lipid raft following the ligation of the epithelial cell membranes with Abs specific for KAT. NHBE cells cultured in the presence of {beta}-methyl cyclodextran ({beta}MCD) had significantly reduced growth factor expression (1.3 {+-} 0.3, vs {beta}MCD untreated being 6.4 {+-} 1.1-fold

    Organ transplants are procedures which require intensive personal and material resources. The results of organ transplants have continuously improved during recent decades. International data bases (registries) have documented the continuous evolution of organ transplantation. On the basis of the German Transplant Law guidelines for "Requirements regarding quality control for procedures related to organ procurement and transplantation" have been formulated by the German Medical Chamber. Thus, monitoring of outcome quality will become a requirement for all German transplant centers. In this paper, the guidelines for the different organ transplants (kidney, pancreas, liver, heart, lung) are discussed as well as quality control for living donor transplantation. Studies from the USA and Europe demonstrated volume-outcome relationships in organ transplantation. In addition, in kidney transplantation a centre-effect could be demonstrated which influences outcome more than the immunological match between donor and recipient. The introduction of required quality control may have far reaching consequences for the future structure of organ transplantation in Germany. PMID:12149941

    In the last 25 years, treatment for small cell lung cancer (SCLC) has improved with advances in chemotherapy and radiotherapy. Standard chemotherapy regimens can yield 80% to 90% response rates and some cures when combined with thoracic irradiation in limited-stage patients. Nonetheless, small cell lung cancer has a high relapse rate due to drug resistance; this has resulted in poor survival for most patients. Attacking this problem requires a unique approach to eliminate resistant disease remaining after induction therapy. This review will focus on three potential strategies: high-dose chemotherapy with autologous bone marrow transplantation, matrix metalloproteinase inhibitors, and BEC2 plus BCG vaccination.

    Background Lung transplantation is considered an established treatment for patients with end-stage chronic respiratory failure. Patients with acute respiratory failure requiring respiratory support with invasive mechanical ventilation while awaiting lung transplantation are at high risk of death. Extracorporeal membrane oxygenation (ECMO) has been proposed as an alternative bridging strategy to mechanical ventilation. The shear stress created by the mechanical pumps causes changes in the hematological system in almost all patients treated with ECMO. An antithrombotic strategy to mitigate ECMO bleeding and thrombotic complications is necessary. The use of thrombolytic therapy is recommended for patients with acute symptomatic embolism with associated hypotension or shock. In this setting, the hemodynamic benefits of thrombolytic treatment far outweigh its bleeding risk. Case presentation This case report describes a 32-year-old woman suffering from lymphangioleiomyomatosis, who underwent urgent double-lung transplantation. This patient was maintained on ECMO preoperatively, perioperatively, and postoperatively due to life-threatening hypoxemia caused by the progression of her pulmonary tissue damage. Multiple thrombi developed in the early postoperative period, in both right and left heart atria. Direct thrombolysis was successfully performed on the first postoperative day. Conclusion According to the current published literature, direct thrombolysis of thrombi in both right and left atria in a patient supported on ECMO following urgent double-lung transplantation is an extremely rare treatment method. Even when taking into account all of the risks associated with thrombolysis and arteriovenous ECMO support, we found that this technique is very effective and, without a doubt, it saved the life of our patient.

    Iran is a tropical country with a land area of 1,648,000 square kilometers and a population of 68,100,000. Iran has a recorded history that dates back 2553 years. Its earliest medical school was Pasargad. Jondi Chapour University was founded 1753 years ago during the Sassanid dynasty as a center for higher education in medicine, philosophy, and pharmacology. Indeed, the idea of xenotransplantation dates back to days of Achaemenidae (Achaemenian dynasty), as evidenced by engravings of many mythologic chimeras still present in Persepolis. Avicenna (980-1037 AD), the great Iranian physician, performed the first nerve repair. Transplantation progress in Iran follows roughly the same pattern as that of the rest of the world, with some 10-20 years' delay. Modern organ transplantation dates back to 1935, when the first cornea transplant was performed at Farabi Hospital in Tehran, Iran. The first living-related kidney transplantation performed at Shiraz University Hospital dates back to 1968. The first bone marrow transplant was performed at Dr. Shariaati's Hospital in Tehran. The first heart transplant was performed 1993 in Tabriz, Iran. The first liver transplant was performed in 1993 in Shiraz. The first lung transplant was performed in 2001, and the first heart and lung transplants were performed in 2002, both at Tehran. In late 1985, the renal transplantation program was officially started in a major university hospital in Tehran and was poised to carry out 2 to 4 transplantations each week. Soon, another large center initiated a similar program. Both of these centers accepted surgical, medical, and nursing teams from other academic medical centers for training in kidney transplantation. Since 2002, Iran has grown to include 23 active renal, 68 cornea, 2 liver, 4 heart, 2 lung, and 2 bone marrow transplantation centers in different cities. In June 2000, the Organ Transplantation Brain Death Act was approved by the Parliament, followed by the establishment of the

    Isolated lung perfusion (ILP) has been historically used as a method to study basic lung physiologic concepts using animal models. More recently, ILP has been applied in lung transplantation and thoracic oncology. In lung transplantation, ILP has been used to assess physiological integrity of donor lungs after the organ is removed from the donor. This procedure is called Ex vivo Lung Perfusion (EVLP), and it has also been proposed as a method for active treatment and repair of injured unsuitable donor organs ex vivo. In oncology, ILP is an attractive method to deliver high dose chemotherapy to treat pulmonary metastatic disease. Since the lung vasculature is isolated in vivo, this technique is called in vivo lung perfusion (IVLP). This review will focus on the rationale, technical aspects, experimental and clinical experience of EVLP and IVLP. A perspective on the future use of these techniques is described. PMID:22202033

    A 17-year-old teen was hospitalized with bilateral pneumothorax. After the bilateral lungs were expanded using catheter tubes, he fully recovered and he was discharged from our hospital. He had a history of colon perforation. Ehlers-Danlos syndrome (EDS) was suspected due to the combination of colon perforation and pneumothorax, and EDS type IV was confirmed after a genetic study identified a c.1511g>a mutation in the COL3A1 gene. This is the first report of bilateral pneumothorax caused by EDS type IV. Clinicians should consider EDS type IV in the differential diagnosis for bilateral pneumothorax in conjunction with distinct previous histories and radiological findings.

    A pulmonary giant hydatid cyst, a special clinical entity, is rare. Our case involves a young patient who presented with a bilaterally symmetrical solitary cyst in each lung, a feature consistent with congenital lung cysts. The radiological and immunological findings were equivocal. A diagnosis of giant hydatid cyst was made intraoperatively and both cysts were removed conservatively. A follow-up showed complete recovery.

    Dyskeratosis congenita is a multisystem genetic disorder. Although hepatic involvement is reported in about 7% of patients with dyskeratosis congenita, it is not well characterized and often attributed to hemochromatosis from frequent blood transfusions. A few case reports describe cirrhosis and hepatic cell necrosis in affected individuals in autosomal dominant pedigrees. Bone marrow failure and malignancies are the principal causes of death in dyskeratosis congenita. We describe the first case of living donor liver transplantation, in dyskeratosis congenita for decompensated cirrhosis with portal hypertension. The patient also had associated severe hepatopulmonary syndrome, interstitial lung disease, bilateral hip replacement for avascular necrosis of the head of femur, and a past history of bone marrow transplantation for bone marrow failure.

    Organising pneumonia is a histopathological entity characterised by intra-alveolar buds of granulation tissue, intermixed myofibroblasts and connective tissue. Cryptogenic organising pneumonia (COP) is characterised by this particular histopathological pattern, along with typical clinical and imaging features, when no other underlying aetiology is found. COP (previously known as bronchiolitis obliterans organising pneumonia [BOOP]) is one of the rare variants of interstitial pneumonias. This condition is characterised by a rapid clinical and radiological improvement with steroid treatment. Here we are reporting a case of COP in adult female with discussion on approach and basic pathophysiology of this type of pneumonia.

    Despite a high prevalence of pancreatic endocrine and exocrine insufficiency in cystic fibrosis (CF), pancreas transplantation is rarely reported. United Network for Organ Sharing (UNOS) data were used to examine utilization of pancreas transplant and posttransplant outcomes in CF patients. Between 1987-2014, CF patients (N = 4600) underwent 17 liver-pancreas, three lung-pancreas, one liver-lung pancreas, four kidney-pancreas, and three pancreas-only transplants. Of the 303 CF patients who received liver transplantation, 20% had CF-related diabetes (CFRD) before transplantation, and nine of those received a liver-pancreas transplant. Of 4241 CF patients who underwent lung transplantation, 33% had CFRD before transplantation, and three of those received a pancreas transplant. Of 49 CF patients who received a liver-lung transplant, 57% had CFRD before transplantation and one received a pancreas transplant. Posttransplantation diabetes developed in 7% of CF pancreas transplant recipients versus 24% of CF liver and 29% of CF lung recipients. UNOS has no data on pancreas exocrine insufficiency. Two-year posttransplantation survival was 88% after liver-pancreas transplant, 33% after lung-pancreas transplant, and 100% after pancreas-kidney and pancreas-only transplants. Diabetes is common pretransplantation and posttransplantation in CF solid organ transplant recipients, but pancreas transplantation remains rare. Further consideration of pancreas transplant in CF patients undergoing other solid organ transplant may be warranted.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    The bilateral operculum syndrome, is a unique developmental syndrome. It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication. We present a 3-year-old boy, apparently the first case of this syndrome to be described in Israel. PMID:8940497

    The Madrid Autonomous Region, a Spanish area with 6,200,000 inhabitants, has 7 hospitals authorized for organ transplantation, with 25 active programs for carrying out various transplantations: 18 for adults and 7 for children. Most of these hospitals are reference transplant centers for other Spanish regions. Between 715 and 760 transplantations are performed annually, which represents between 19% and 22% of Spanish activity. During 2007, 395 kidney, 220 liver, 55 heart, and 35 lung transplantations were performed, as well as 23 isolated or combination transplantations of other abdominal organs (pancreatic, intestinal, or multivisceral). Kidney, liver, heart, and children's intestinal transplant activity in 2007 represented 37%, 63%, 80%, and 100%, respectively, of all pediatric national activity. The Madrid Autonomous Region has a donation rate of 34.2 donors per million inhabitants. Of these, 30% are from non-heart-beating donors (NHBD), Maastrich criteria category 1 or 2. Various hospitals perform kidney, liver, and lung transplantations with these organs, representing 11% of the lung transplantations carried out in recent years, with this being a pioneer procedure worldwide. Despite the important transplant activity, we are working to increase donations, to improve organ donor detection and management protocols, as well as to reach a consensus on criteria to decrease the nonviability rates of potential transplant organs.

    Pulmonary hypertension associated with left heart disease is the most common form of pulmonary hypertension encountered in clinical practice today. Although frequently a target of therapy, its pathophysiology remains poorly understood and its treatment remains undefined. Pulmonary hypertension in the context of left heart disease is a marker of worse prognosis and disease severity, but whether its primary treatment is beneficial or harmful is unknown. An important step to the future study of this important clinical problem will be to standardize definitions across disciplines to facilitate an evidence base that is interpretable and applicable to clinical practice. In this current statement, we provide an extensive review and interpretation of the current available literature to guide current practice and future investigation. At the request of the Pulmonary Hypertension (PH) Council of the International Society for Heart and Lung Transplantation (ISHLT), a writing group was assembled and tasked to put forth this document as described above. The review process was facilitated through the peer review process of the Journal of Heart and Lung Transplantation and ultimately endorsed by the leadership of the ISHLT PH Council. PMID:22884380

  17. Echinoderms Have Bilateral Tendencies

    PubMed Central

    2012-01-01

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    Lung transplantation (LTx) is an established treatment option for eligible patients with end-stage lung disease. Nevertheless, the imbalance between suitable donor lungs available and the increasing number of patients considered for LTx reflects in considerable waitlist mortality. Among potential alternatives to address this issue, ex vivo lung perfusion (EVLP) has emerged as a modern preservation technique that allows for more accurate lung assessment and also improvement of lung function. Its application in high-risk donor lungs has been successful and resulted in safe expansion of the donor pool. This article will: (I) review the technical details of EVLP; (II) the rationale behind the method; (III) report the worldwide clinical experience with the EVLP, including the Toronto technique and others; (IV) finally, discuss the growing literature on EVLP application for donation after cardiac death (DCD) lungs.

Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

    Hair transplantation is a purely dermatologic surgical procedure that dermatologists should be able to perform in appropriate candidates with hair loss. Hair transplantation techniques performed in the 1960s through the 1990s utilized large grafts that created an unfortunate public image of unnatural-appearing transplanted hair. Over the last 15 years, hair transplantation has been performed using follicular units to create consistently natural-looking transplanted hair in both men and women. This article provides an overview of candidate selection and state-of-the-art techniques for performing hair transplantation.

    Patients with bilateral urolithiasis diagnosed at their first visit were followed for at least one year after the start of treatment. In this retrospective study of 123 patients, the basic metabolic workup revealed no specific underlying cause of simultaneously occurring bilateral nephrolithiasis, and none of the currently used therapeutic regimes proved to be efficient in attaining clinically acceptable stone-free rates at the 3, 6 and 12-month follow-ups. Of 38 patients treated with extracorporeal shockwave lithotripsy (SWL), 21 underwent treatment of both kidneys and 10 (48%) were free of stones bilaterally after 12 months. All of the 17 patients treated with unilateral SWL failed to achieve a stone-free state on the contralateral side. In another group, treated with medication alone to minimize risks of stone recurrence, only 3 of 26 (11.5%) patients were stone-free on both sides 12 months after the start of medication. Since we achieved a stone-free state of both kidneys in no more than 12% of the non-medicated cases, it seems warranted to treat bilateral urolithiasis with SWL more frequently, particularly when patients cannot return regularly to the stone clinic for a longterm follow-up.

  5. Bilateral undescended testes.

    1993-01-01

    The management of boys with undescended testes appears to be an increasingly common problem. While Scorer (1964) [11] reported an incidence of 0.8% of undescended testes in boys of one year of age, a recent survey (Radcliffe Hospital, Oxford, 1986) [18] suggests the incidence has risen to as high as 1.6%. While the etiology may be varied, it is quite clear that many cases represent disturbances of the hypothalamic-pituitary-gonadal axis and may represent a forme fruste of hypogonadotropic hypogonadism [3]. Bilateral undescended testes might logically appear to represent the worst end of such an endocrinopathy. Indeed, a review of the experience at The Children's Hospital of Philadelphia [12] of boys with bilateral undescended testes indicated a greater number of CNS abnormalities (P = 0.0000) than in boys with unilateral undescended testes (Table 1). Also consistent with bilateral cryptorchid testes representing the most severe end of the spectrum was the reported findings from that study that bilateral undescended testes also exhibit a significantly greater number of associated G-U anomalies (P = 0.0004).

    Introduction Renal lymphangiomatosis is a rare congenital benign disease of renal lymphatic system, here we are presenting a very rare form of disease which is bilateral form. Presentation of the case A young adult presented to our clinic after being referred from primary care clinic with intermittent bilateral flank pain and no other symptoms after extensive radiological investigations diagnosis has been made and confirmed by radiological finding of disease. Active treatment usually preserved for complex cases and for the complications of the disease but in our patient as needed analgesia worked well in controlling his intermittent pain and his wish not to pursue any intervention. The vague presentation with initial imaging rising suspicion of renal tumor or complex renal cyst might cause psychological street on the patient, which our patient had, but reassurance after extensive radiological work up relive that's stress. Discussion Although it is very rare disease to be bilateral but wide variety of other differential diagnoses make importance of disease recognition and accurate diagnosis is the key. Conclusion Renal lymphangiomatosis is a rare benign disease of renal lymphatic, which usually affect one side, but bilateral form is very rare form, which may raise the suspicions of genetic form of renal malignancy. Accurate diagnosis requires work up to role out malignant and other renal tumor, which require active surgical management. PMID:26719997

    1996-10-01

    It is generally thought that simultaneous bilateral chest surgery carries a high morbidity. We reviewed the results of simultaneous (under one anesthesia) vs staged bilateral video-assisted thoracoscopic surgery (VATS) from a single institution over a 35-month period. From September 1992 to July 1995, we performed simultaneous bilateral VATS on 37 patients (31 males, six females, age ranging from 15 to 55 years) with spontaneous pneumothorax (20) for bleb resections and pleurodesis; thoracodorsal sympathectomy (12) for palmar hyperhidrosis and vasospastic disease; and metastatic sarcomas (five) for wedge lung resections. During the same period, nine patients with metachronous bilateral spontaneous pneumothorax had staged procedures, as did two with digital ischemic ulcers for sympathectomy and three with metastatic pulmonary osteosarcomas for resection. Mean postoperative hospital stays in days for the simultaneous groups were 3.3 for spontaneous pneumothorax, 2.1 for sympathectomy, and 1.5 for wedge resection, compared to 2.9, 2.5, and 2.2 for the staged groups, respectively (p > 0.05 by Mann-Whitney U tests). Likewise, pain assessment by visual analogue scale as well as analgesic requirement showed no significant difference between the simultaneous and the staged groups. We conclude that simultaneous VATS is not associated with increased morbidity or prolonged hospital stay compared to the staged counterparts and provides an attractive alternative to the median sternotomy, bilateral posterolateral thoracotomy, or transternal (clam-shell) thoracotomy for selected cases of simultaneous bilateral lung surgery.

    Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation. If the pneumothorax is significant, it can cause a shift of the mediastinum and compromise haemodynamic stability. While 10% of pneumothoraces are asymptomatic, patients often complain of acute chest pain and difficulty breathing. There is a reduction in vital capacity, tachycardia, tachypnoea and a decrease in partial pressure of oxygen with an inability to maintain oxygen saturations. We observed this unusual surgical consequence in a 28-year-old female with negative clinical history and instrumental evaluation after Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO). No further consequences, no neurological sequelae, no infections and no other osteotomies sequelae were seen. Sudden post-surgical dispnea associated to sub-cutaneous emphysema of the neck and of the thorax must be adequately observed with the aim of monitoring further severe sequelae. The anaesthetic management of the emergency difficult airway in any post-surgical orthognatic treatment can be extremely difficult requiring a multi-disciplinary approach. PMID:23814593

Case Report: A 44-year-old lady presented with bilateral visual loss of 8 months’duration. Considering the presence of pan-uveitis, severe macular edema, multifocal leakage on fluorescein angiography, positive tuberculin skin test, and after excluding other diseases, she underwent anti-tuberculous therapy (ATT) for disseminated choroiditis due to presumed ocular tuberculosis. She improved promptly and completely. There were no signs of relapse 18 months after completion of the treatment course. In a young patient with disseminated choroiditis and relatively short duration of symptoms, a course of ATT for 6 months may effectively treat the disease preventing relapse for a considerable period of time. Conclusion: In Presumed Tuberculous chroiditis early diagnosis is crucial for prompt and complete improvement. PMID:27413507

  15. Bilateral parotid neoplasms.

    PubMed

    Williams, C

    1980-09-01

    We are reporting what we believe to be the second case of bilateral parotid neoplasm occuring synchronously with differing histologies. We believe that this neoplasm may represent a specific propensity of parotid tissue in a given individual to develop neoplasia in a multipotential glandular organ subject to many neoplastic diseases. There also exists the possibility that this condition may represent an immune deficiency specific to the parotid gland. The case reports that have been reviewed demonstrate that a secondary neoplasm may arise from benign mixed tumors. We question whether this is an example of monistic origin of acinic cell tumor from a mixed-cell tumor or, perhaps, dualistic expression for this salivary gland to develop a multiplicity of anaplastic and metaplastic growth variants. In approaching a case with bilateral parotid involvement, the physician must be aware of the rare possibility that benign and malignant tumors may coexist. He must be prepared to proceed with more radical extirpation than simple superficial parotidectomy.

    Hair transplantation is a technique in which hair follicles are harvested from the occipital area and re-transplanted in the frontal bald area. Hair transplantation is the most common cosmetic procedure in the United States nowadays despite the fact that it is expensive. Usually, patients need more than one session to receive a cosmetically acceptable result and patients need to be understanding and have realistic expectations. Although most of our patients are males, females represent about 10-15% of our new patients. This article reviews the basic principals of hair transplantation and describes new and improved techniques of hair transplantation. PMID:11376357

    Patients with hepatic sarcoidosis rarely require orthotopic liver transplantation (OLT). Progression of granulomatous activity involving other organs after OLT has rarely been described. We describe a 32-year-old woman who underwent liver transplantation for sarcoidosis-associated end-stage liver disease. She presented 4 years later with shortness of breath, hilar lymphadenopathy, and interstitial lung abnormalities. Liver functions were normal. Open lung biopsy results revealed granulomata compatible with sarcoidosis. The patient made a complete recovery after corticosteroid treatment. To the best of our knowledge, this is a first description of severe exacerbation of pulmonary sarcoidosis in an immunosuppressed patient who underwent liver transplantation for sarcoidosis-associated liver disease.

  20. Multispectral bilateral video fusion.

    Bennett, Eric P; Mason, John L; McMillan, Leonard

    2007-05-01

    We present a technique for enhancing underexposed visible-spectrum video by fusing it with simultaneously captured video from sensors in nonvisible spectra, such as Short Wave IR or Near IR. Although IR sensors can accurately capture video in low-light and night-vision applications, they lack the color and relative luminances of visible-spectrum sensors. RGB sensors do capture color and correct relative luminances, but are underexposed, noisy, and lack fine features due to short video exposure times. Our enhanced fusion output is a reconstruction of the RGB input assisted by the IR data, not an incorporation of elements imaged only in IR. With a temporal noise reduction, we first remove shot noise and increase the color accuracy of the RGB footage. The IR video is then normalized to ensure cross-spectral compatibility with the visible-spectrum video using ratio images. To aid fusion, we decompose the video sources with edge-preserving filters. We introduce a multispectral version of the bilateral filter called the "dual bilateral" that robustly decomposes the RGB video. It utilizes the less-noisy IR for edge detection but also preserves strong visible-spectrum edges not in the IR. We fuse the RGB low frequencies, the IR texture details, and the dual bilateral edges into a noise-reduced video with sharp details, correct chrominances, and natural relative luminances.

    Although great progress has been achieved in thoracic organ transplantation through the development of effective immunosuppression, there is still significant risk of rejection during the early post-transplant period, creating a need for routine monitoring for both acute antibody and cellular mediated rejection. The currently available multiplexed, microbead assays utilizing solubilized HLA antigens afford the capability of sensitive detection and identification of HLA and non-HLA specific antibodies. These assays are being used to assess the relative strength of donor specific antibodies; to permit performance of virtual crossmatches which can reduce the waiting time to transplantation; to monitor antibody levels during desensitization; and for heart transplants to monitor antibodies post-transplant. For cell mediated immune responses, the recent development of gene expression profiling has allowed noninvasive monitoring of heart transplant recipients yielding predictive values for acute cellular rejection. T cell immune monitoring in heart and lung transplant recipients has allowed individual tailoring of immunosuppression, particularly to minimize risk of infection. While the current antibody and cellular laboratory techniques have enhanced the ability to manage thoracic organ transplant recipients, future developments from improved understanding of microchimerism and graft tolerance may allow more refined allograft monitoring techniques.

    We present a case of simultaneous bilateral spontaneous pneumothorax caused by a pleuro-pleural communication formed from Nuss procedure for pectus excavatum. A 17-year-old man with a history of Nuss operation complained chest pain and dyspnea. A chest roentgenogram demonstrated a tiny bilateral pneumothorax and two metallic bars inserted at the Nuss procedure. Computed tomography revealed furthermore a bulla in the apex of the left lung. The bilateral pneumothorax critically deteriorated after 4 days from onset and urgent bilateral chest drainages were performed. Nevertheless the drainages the full expansion of both lungs was not obtained and air leakage only from left side was continued. A video-assisted left bullectomy was performed 9 days after the tube insertion. The two bars penetrating anterior mediastinal pleura were thought to be a cause of the simultaneous bilateral spontaneous pneumothorax.

    Lung transplantation remains the gold standard for patients with end-stage lung disease. Nevertheless, the number of suitable donor lungs for the increasing number of patients on the waiting list necessitates alternative tools to expand the lung donor pool. Modern preservation and lung assessment techniques could contribute to improved function in previously rejected lungs. Ex vivo lung perfusion (EVLP) already demonstrated its value in identification of transplantable grafts from the higher risk donor pool. Moreover, lungs from EVLP did not show significantly different postoperative results compared to standard criteria lungs. This could be explained by the reduction of the ischemia-reperfusion injury through EVLP application. The aim of this article is to review technical characteristics and the growing clinical EVLP experience with special attention to EVLP application for donation after cardiac death (DCD) lungs.

    Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual(1). Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation.

    Though parasitic lung diseases are frequently seen in tropical countries, these are being increasingly reported from many parts of the world due to globalisation and travel across the continents. In addition, the emergence of human immunodeficiency virus (HIV) infection/acquired immunodeficiency syndrome (AIDS), the frequent use of immunosuppressive drugs in many diseases and the increasing numbers of organ transplantations have resulted in a renewed interest in many tropical parasitic lung diseases. This review outlines the recent developments in the pathogenesis, diagnosis and management of common and rare parasitic lung diseases.

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Wilms' tumor occurs in 5-10 % of all cases of nephroblastoma. The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous tumors appear within the first 5 years of the primary tumor. Associated malformations are more common in bilateral cases. Metachronous tumors are a therapeutic challenge. We describe the case of an 11-year-old girl with left hemihypertrophy. The diagnosis was metachronous relapse of Wilms' tumor 7 years after the first diagnosis. The patient received five courses of preoperative chemotherapy and tumorectomy was performed. Because of post-surgical complications, nephrectomy was performed on her only kidney. Since she is anephric, the patient is in chronic renal failure and is dependent on dialysis. Treatment with carboplatin and etoposide was continued after surgery and the patient is currently in complete remission. The appearance of a metachronous Wilms' tumor 5 years after that of the primary tumor is rare. When a contralateral tumour develops, chemotherapy must be given until the size of the tumor is reduced in order to preserve renal function and avoid dialysis. In patients with chronic renal failure caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.

  12. Challenges in transplantation for alcoholic liver disease.

    PubMed

    Berlakovich, Gabriela A

    2014-07-01

    Transplantation for the treatment of alcoholic cirrhosis is more controversially discussed than it is for any other indication. The crucial aspect in this setting is abstinence before and after liver transplantation. We established pre-transplant selection criteria for potential transplant candidates. Provided that the underlying disease can be treated, there is no reason to withhold liver transplantation in a patient suffering from alcoholic cirrhosis. Evaluation of the patient by a multidisciplinary team, including an addiction specialist, is considered to be the gold standard. However, several centers demand a specified period of abstinence - usually 6 mo- irrespective of the specialist's assessment. The 6-mo rule is viewed critically because liver transplantation was found to clearly benefit selected patients with acute alcoholic hepatitis; the benefit was similar to that achieved for other acute indications. However, the discussion may well be an academic one because the waiting time for liver transplantation exceeds six months at the majority of centers. The actual challenge in liver transplantation for alcoholic cirrhosis may well be the need for lifelong post-transplant follow-up rather than the patient's pre-transplant evaluation. A small number of recipients experience a relapse of alcoholism; these patients are at risk for organ damage and graft-related death. Post-transplant surveillance protocols should demonstrate alcohol relapse at an early stage, thus permitting the initiation of adequate treatment. Patients with alcoholic cirrhosis are at high risk of developing head and neck, esophageal, or lung cancer. The higher risk of malignancies should be considered in the routine assessment of patients suffering from alcoholic cirrhosis. Tumor surveillance protocols for liver transplant recipients, currently being developed, should become a part of standard care; these will improve survival by permitting diagnosis at an early stage. In conclusion, the key

    2016-01-01

    Abstract Cytomegalovirus (CMV) is a highly complex pathogen which, despite modern prophylactic regimens, continues to affect a high proportion of thoracic organ transplant recipients. The symptomatic manifestations of CMV infection are compounded by adverse indirect effects induced by the multiple immunomodulatory actions of CMV. These include a higher risk of acute rejection, cardiac allograft vasculopathy after heart transplantation, and potentially bronchiolitis obliterans syndrome in lung transplant recipients, with a greater propensity for opportunistic secondary infections. Prophylaxis for CMV using antiviral agents (typically oral valganciclovir or intravenous ganciclovir) is now almost universal, at least in high-risk transplants (D+/R−). Even with extended prophylactic regimens, however, challenges remain. The CMV events can still occur despite antiviral prophylaxis, including late-onset infection or recurrent disease, and patients with ganciclovir-resistant CMV infection or who are intolerant to antiviral therapy require alternative strategies. The CMV immunoglobulin (CMVIG) and antiviral agents have complementary modes of action. High-titer CMVIG preparations provide passive CMV-specific immunity but also exert complex immunomodulatory properties which augment the antiviral effect of antiviral agents and offer the potential to suppress the indirect effects of CMV infection. This supplement discusses the available data concerning the immunological and clinical effects of CMVIG after heart or lung transplantation. PMID:26900989

    The number of patients listed for lung transplantation largely exceeds the number of available transplantable organs because of both a shortage of organ donors and a low utilization rate of donor lungs. Normothermic ex vivo lung perfusion (EVLP) is a method that maintains the organ in physiologically protective conditions outside the body during preservation, and shows great promise to increase utilization of donor lungs by allowing more accurate evaluation, as well as treatment and repair, of damaged donor lungs prior to transplantation. This article will cover the rationale, technical details and results of experimental and clinical studies with EVLP. The significant potential applications of EVLP in lung transplantation, lung regeneration and oncology are discussed. PMID:22283576

    Bronchiectasis is a major cause of morbidity and mortality in developing countries. Staged bilateral segmental resection of the lungs is performed in selected patients. Our experience of surgical removal of 87 bilateral bronchiectases in 29 patients during an 11-year period was reviewed retrospectively. High-resolution computed tomography was performed preoperatively in all patients to locate the anatomic sites of bronchiectasis. The mortality and morbidity of the surgical procedure, clinical symptoms, age distribution, etiology, bacteriology, and operative procedures were analyzed. There were 22 males (76%) and 7 females (24%), aged 5 to 60 years, with a mean age of 30 years. Complications developed in 11 patients (38%); atelectasia was the most common (14%). There was one hospital death. Clinical symptoms disappeared in 19 (66%) patients, improved in 5 (17%), and were unchanged in 4 (14%). Staged bilateral resection for bronchiectases can be performed at any age with acceptable morbidity and mortality. PMID:16714699

    Pediatric lung diseases remain a costly worldwide health burden. For many children with end-stage lung disease, lung transplantation remains the only therapeutic option. Due to the limited number of lungs available for transplantation, alternatives to lung transplant are desperately needed. Recently, major improvements in tissue engineering have resulted in newer technology and methodology to develop viable bioengineered lungs. These include critical advances in lung cell biology, stem cell biology, lung extracellular matrix, microfabrication techniques, and orthotopic transplantation of bioartificial lungs. The goal of this short review is to engage the reader’s interest with regard to these emerging concepts and to stimulate their interest to learn more. We review the existing state of the art of lung tissue engineering, and point to emerging paradigms and platforms in the field. Finally, we summarize the challenges and unmet needs that remain to be overcome. PMID:26106589

    2014-12-01

    Although transplantation has been a standard medical practice for decades, marked morbidity from the use of immunosuppressive drugs and poor long-term graft survival remain important limitations in the field. Since the first solid organ transplant between the Herrick twins in 1954, transplantation immunology has sought to move away from harmful, broad-spectrum immunosuppressive regimens that carry with them the long-term risk of potentially life-threatening opportunistic infections, cardiovascular disease, and malignancy, as well as graft toxicity and loss, towards tolerogenic strategies that promote long-term graft survival. Reports of "transplant tolerance" in kidney and liver allograft recipients whose immunosuppressive drugs were discontinued for medical or non-compliant reasons, together with results from experimental models of transplantation, provide the proof-of-principle that achieving tolerance in organ transplantation is fundamentally possible. However, translating the reconstitution of immune tolerance into the clinical setting is a daunting challenge fraught with the complexities of multiple interacting mechanisms overlaid on a background of variation in disease. In this article, we explore the basic science underlying mechanisms of tolerance and review the latest clinical advances in the quest for transplantation tolerance. PMID:24213880

    BACKGROUND—Respiratory function in transplanted children is important because of the long life expectancy of bone marrow transplant recipients, particularly children. Attention is now being focused on the late sequelae of treatment on organ system function. A few papers have been published but available data are somewhat conflicting.
METHODS—A cross sectional study aimed at evaluating the late effects of transplantation on lung function was performed in a group of 52 young patients who were given autologous or allogeneic bone marrow transplants during childhood for haematological malignancies.
RESULTS—No patients reported chronic respiratory symptoms. The distribution of respiratory function patterns showed that only 62% of patients had respiratory function within the normal limits; 23% had a restrictive pattern and 15% had isolated transfer factor impairment. The percentage of patients with lung function abnormalities was higher in those who (1) received a bone marrow transplant after two or three complete remissions compared with those who were transplanted immediately after the first remission (54% vs 21%; p<0.02), (2) underwent allogeneic bone marrow transplantation rather than an autologous transplantation (45% vs 26%; p = 0.06), and (3) had a pulmonary infection compared with those without (56% vs 26%; p = 0.07).
CONCLUSIONS—In spite of the absence of chronic respiratory symptoms there is a high prevalence of children with late pulmonary sequelae after bone marrow transplantation. Regular testing is recommended after transplantation, in particular in subjects at higher risk of lung injuries, such as those receiving transplants after more than one remission, those receiving allogeneic transplants, and those having suffered from pulmonary infections. When lung function abnormalities become apparent, long term follow up is necessary to see whether they become clinically relevant. All patients should remain non-smokers after transplantation and

    Kidney and corneal transplants have been undertaken since the seventies although other forms of organ transplantation were lesser known. To date more than 1000 kidney transplants, the majority from living related donors have been performed. Nevertheless heart, lung and liver transplant only had an impact in the nineties. The main reason being, the lack of cadaveric donors, which has hampered the development of organ transplantation in Malaysia. It is instructive to note that the Malaysian society has been rather conservative when it comes to organ transplantation. This is compounded by the Asean culture and value system, which are directly derived from our historical background and religious convictions. However attempts had been made by various organisations such as The Malaysian Society of Transplantation, which was set up in 1994 to create greater awareness on organ donation & transplantation amongst both the healthcare professionals and the public.

    We present a case of acute silicosis with bilateral pneumothorax of a 28-year-old man working at a stone crusher factory for 1 year. He presented to the emergency department with cough, respiratory distress and diffuse chest pain. The patient was managed with bilateral intercostal tube drainage under water seal, oxygen inhalation and conservative therapy. On follow-up he showed improvement of resting dyspnoea and was doing well. This case is being reported because of the rare complications of acute silicosis as bilateral pneumothorax. PMID:24862410

    A 77-year-old man, who received a renal transplant 13 years before for IgA glomerulonephritis, was referred after he developed bilateral mid-tibial aching pain that did not improve with simple analgesia. He had recently been changed from low-dose cyclosporine to tacrolimus, but the pain did not improve when this was reversed. He had a history of focal prostatic adenocarcinoma, cryptococcal lung infection, osteoporosis treated with alendronate for 2 years and multiple squamous cell carcinomas, including one requiring left neck dissection and radiotherapy. Upon physical examination, he had gouty tophi and marked bilateral tibial tenderness but had no other clinical findings. Laboratory investigations included an elevated intact parathyroid hormone value of 7.9 pmol/L (1.6 to 6.9), bone specific alkaline phosphatase of 22 µg/L (3.7 to 20.9), urinary deoxypyridinoline/creatinine ratio of 7.2 nmol/mmol (2.5 to 5.4) and C-reactive protein. Chest X-ray and tibial X-rays were normal, but there was marrow oedema and a prominent periosteal reaction on magnetic resonance imaging. A radionuclide bone scan showed increased symmetrical, linear uptake in both tibiae and the left femur, and uptake was also noted in both clinically asymptomatic humeri. Tibial bone biopsy disclosed small deposits of poorly differentiated metastatic cancer and a follow-up chest CT revealed a lung lesion. It was concluded that the bone pain and periostitis was caused by primary lung cancer with metastatic disease to bone, and an associated hypertrophic osteoarthropathy.

    Solid organ transplantation has transformed the lives of many children and adults by providing treatment for patients with organ failure who would have otherwise succumbed to their disease. The first successful transplant in 1954 was a kidney transplant between identical twins, which circumvented the problem of rejection from MHC incompatibility. Further progress in solid organ transplantation was enabled by the discovery of immunosuppressive agents such as corticosteroids and azathioprine in the 1950s and ciclosporin in 1970. Today, solid organ transplantation is a conventional treatment with improved patient and allograft survival rates. However, the challenge that lies ahead is to extend allograft survival time while simultaneously reducing the side effects of immunosuppression. This is particularly important for children who have irreversible organ failure and may require multiple transplants. Pediatric transplant teams also need to improve patient quality of life at a time of physical, emotional and psychosocial development. This review will elaborate on the long-term outcomes of children after kidney, liver, heart, lung and intestinal transplantation. As mortality rates after transplantation have declined, there has emerged an increased focus on reducing longer-term morbidity with improved outcomes in optimizing cardiovascular risk, renal impairment, growth and quality of life. Data were obtained from a review of the literature and particularly from national registries and databases such as the North American Pediatric Renal Trials and Collaborative Studies for the kidney, SPLIT for liver, International Society for Heart and Lung Transplantation and UNOS for intestinal transplantation.

    2011-01-01

    About 10% of all renal allografts fail during the first year of transplantation and thereafter approximately 3%-5% yearly. Given that approximately 69 400 renal transplants are performed worldwide annually, the number of patients returning to dialysis following allograft failure is increasing. A failed transplant kidney, whether maintained by low dose immunosuppression or not, elicits an inflammatory response and is associated with increased morbidity and mortality. The risk for transplant nephrectomy (TN) is increased in patients who experienced multiple acute rejections prior to graft failure, develop chronic graft intolerance, sepsis, vascular complications and early graft failure. TN for late graft failure is associated with greater morbidity and mortality, bleeding being the leading cause of morbidity and infection the main cause of mortality. TN appears to be beneficial for survival on dialysis but detrimental to the outcome of subsequent transplantation by virtue of increased level of antibodies to mismatched antigens, increased rate of primary non function and delayed graft function. Many of the studies are characterized by a retrospective and univariate analysis of small numbers of patients. The lack of randomization in many studies introduced a selection bias and conclusions drawn from such studies should be applied with caution. Pending a randomised controlled trial on the role of TN in the management of transplant failure patients, it is prudent to remove failed symptomatic allografts and all grafts failing within 3 mo of transplantation, monitor inflammatory markers in patients with retained failed allografts and remove the allograft in the event of a significant increase in levels.

    Summary We previously identified plasma plasminogen activator inhibitor-1 (PAI-1) level as a quantitative lung injury biomarker in PGD. We hypothesized plasma levels of PAI-1 used as a quantitative trait could facilitate discovery of genetic loci important in PGD pathogenesis. A 2-stage cohort study was performed. In stage 1, we tested associations of loci with PAI-1 plasma level using linear modeling. Genotyping was performed using the Illumina CVD Bead Chip v2. Loci meeting a p<5×10−4 cutoff were carried forward and tested in Stage 2 for association with PGD. 297 enrollees were evaluated in Stage 1. 6 loci, associated with PAI-1, were carried forward to Stage 2 and evaluated in 728 patients. rs3168046 (Toll interacting protein, TOLLIP) was significantly associated with PGD (p=0.006). The increased risk of PGD for carrying at least one copy of this variant was 11.7% [95% CI: 4.9%, 18.5%]. The false positive rate for individuals with this genotype who did not have PGD was 6.1%. Variants in the TOLLIP gene are associated with higher circulating PAI-1 plasma levels and validate for association with clinical PGD. A protein quantitative trait analysis for PGD risk prioritizes genetic variations in TOLLIP, and supports a role for toll-like receptors in PGD pathogenesis. PMID:26663441

    Lung donation and transplantation is increasing in volume annually, yet there continues to be a shortage of available organs for transplant. Despite this shortage, suitable lungs are occasionally not transplanted due to logistical issues. Issues such as time and distance can be a major barrier in deceased donor organ recovery and transplantation. This single case study serves as an example of the teamwork and cooperation that resulted in the successful transplantation of lungs in spite of long-distance logistical issues between the donor and the recipient. All of the members who contributed to this collaboration recognized the need and urgency to overcome these challenges. The organ procurement organization's collaboration with multiple transplant centers across multiple regions resulted in a successful outcome for the lung recipient.

    Restorative potential of fetal neural transplantation in colchicine induced neurodegeneration was studied in rats; where colchicine (2.5mg per site) was administered bilaterally into the hippocampus followed by bilateral infusions of fetal neural cell suspension rich in cholinergic neurons as single macro- or multiple micro-transplants in the hippocampal region 3 weeks post-colchicine (2.5mg per site) lesion. Animals were studied for neuro behavioural and neurochemical recovery at 4 and 24 weeks post-transplantation and electrophysiological (single cell recording) and immunohistochemical parameters, choline acetyl transferase (ChAT) expression was studied in hippocampus at 24 weeks post-transplantation. Colchicine lesioned rats receiving single macro- or multiple micro-transplants exhibited significant restoration in cognitive dysfunction caused by colchicine after 4 weeks of transplantation which remain persistent in multiple micro-transplanted group upto 24 weeks post-transplantation, whereas, single macro-transplanted animals did not exhibit any significant recovery. Neurochemical studies revealed significant restoration in acetylcholine esterase activity and cholinergic (muscarinic) receptor binding after 24 weeks post-transplantation as compared to 4 weeks post-transplantation in multiple micro-transplanted group. Single cell recording studied at 24 weeks post-transplantation exhibited significant restoration in firing rates when compared with lesioned group. The viability of cholinergic fibre at transplanted sites has further been confirmed by increase in ChAT immuno positivity in hippocampal region using monoclonal antibody and quantified using image analyser Leica Qwin 500 software. The results suggest that intra-hippocampal multiple site cholinergic rich transplants provide better and long term restoration in the cholinergic deficits induced by colchicine lesion as compared to single site macro-transplantation.

    The incidence of invasive fungal infection (IFI) has increased considerably over the past 20 years, and transplant recipients are at especially high risk for fungal infections owing to their overall immunosuppressed condition. Organ transplantation procedures were incorporated as a therapeutic option for many patients who lacked the normal functions of organs such as the heart, liver, kidney, lung, pancreas and small bowel. The prevalence of IFI in solid organ transplant (SOTR) patients ranges from 5 to 50% in kidney and liver transplants, respectively. In bone marrow transplant (BMT) patients, IFI are major causes of morbidity and mortality due to the protracted neutropenic period and graft-versus-host disease. Candida spp. and Aspergillus spp. account for >80% of fungal episodes in both SOTR and BMT. The development of new immunosuppressive agents, new prophylaxis strategies (as pre-emptive therapy) and the improvement in surgical techniques led to increase survival of transplant recipients. In this session, a clear and concise update of the recent advances in the laboratory diagnosis of candidiasis and aspergillosis in this kind of patients was presented. However, we still need to establish more rapid, sensitive and specific methods for IFI diagnosis. Representatives of the 'Subcomision de Infecciones en el Paciente Neutropenico y Transplantado (SIPNYT)' de la Sociedad Argentina de Infectologia (SADI), presented the results of an unusual multicenter study both retrospective and descriptive studies of IFI in SOTR and BMT patients in Argentina. In addition, a study of IFI in 1,861 SOTR patients from four centers and the analysis of IFI in 2,066 BMT patients from all 12 BMT centers from Argentina was presented. From these studies it can be concluded that 'all transplant recipients are not the same' and that they should be stratified according to their different risk degrees in order to determine the best prophylaxis and treatment strategies.

    The major challenge in transplantation medicine remains long-term allograft acceptance, with preserved allograft function under minimal chronic immunosuppression. To safely achieve the goal of sustained donor-specific T and B cell non-responsiveness, research efforts are now focusing on therapies based on cell subsets with regulatory properties. In particular the transfusion of human regulatory T cells (Treg) is currently being evaluated in phase I/II clinical trials for the treatment of graft versus host disease following hematopoietic stem cell transplantation, and is also under consideration for solid organ transplantation. The purpose of this review is to recapitulate current knowledge on naturally occurring as well as induced human Treg, with emphasis on their specific phenotype, suppressive function and how these cells can be manipulated in vitro and/or in vivo for therapeutic purposes in transplantation medicine. We highlight the potential but also possible limitations of Treg-based strategies to promote long-term allograft survival. It is evident that the bench-to-beside translation of these protocols still requires further understanding of Treg biology. Nevertheless, current data already suggest that Treg therapy alone will not be sufficient and needs to be combined with other immunomodulatory approaches in order to induce allograft tolerance.

    Transplantation is the accepted mode of treatment for patients with end-stage organ disease affecting the heart, lungs, kidney, pancreas, liver and intestine. Long-term outcomes have significantly improved and the aim of management is no longer only long-term survival, but also focuses on quality of life especially in children. Transplantation in Africa faces a number of challenges including wide socioeconomic disparity, lack of legislation around brain death and organ donation in many countries, shortage of skilled medical personnel and facilities, infectious disease burden and insecure access to and monitoring of immunosuppression. Whilst there is a need for transplantation, the establishment and sustainability of transplant programmes require careful planning with national government and institutional support. Legislation regarding brain death diagnosis and organ retrieval/donation; appropriate training of the transplant team; and transparent and equitable criteria for organ allocation are important to establish before embarking on a transplant programme. Establishing sustainable, self-sufficient transplant programmes in Africa with equal access to all citizens is an important step towards curtailing transplant tourism and organ trafficking and has a further beneficial effect in raising the level of medical and surgical care in these countries.

    Transplantation medicine is an interdisciplinary task and the priority objective is a fast recovery to patient independence. After kidney transplantation the crucial aims are monitoring of transplant perfusion, maintainance of an adequate volume status and avoidance of nephrotoxic medications. Transplantation for patients with advanced chronic liver failure has become more common since the implementation of the model of end stage liver disease (MELD) allocation system which is associated with more complicated proceedings. The essentials of critical care after liver transplantation are monitoring of transplant function, diagnosis of perfusion or biliary tract problems, specific substitution of coagulation factors and hemodynamic optimation due to avoidance of hepatic congestion. Many patients listed for heart transplantation need preoperative intensive care due to impaired heart function. Postoperatively a specific cardiac support with pulmonary arterial dilatators and inotropics is usually necessary. Lung transplantation aims at an improvement of patient quality of life. Postoperative critical care should provide a limitation of the pulmonary arterial pressure, avoidance of volume overload and rapid weaning from the respirator.

    2015-04-01

    Acute respiratory distress syndrome (ARDS) and its milder form acute lung injury (ALI) may result from various diseases and situations including sepsis, pneumonia, trauma, acute pancreatitis, aspiration of gastric contents, near-drowning etc. ALI/ARDS is characterized by diffuse alveolar injury, lung edema formation, neutrophil-derived inflammation, and surfactant dysfunction. Clinically, ALI/ARDS is manifested by decreased lung compliance, severe hypoxemia, and bilateral pulmonary infiltrates. Severity and further characteristics of ALI/ARDS may be detected by biomarkers in the plasma and bronchoalveolar lavage fluid (or tracheal aspirate) of patients. Changed concentrations of individual markers may suggest injury or activation of the specific types of lung cells-epithelial or endothelial cells, neutrophils, macrophages, etc.), and thereby help in diagnostics and in evaluation of the patient's clinical status and the treatment efficacy. This chapter reviews various biomarkers of acute lung injury and evaluates their usefulness in diagnostics and prognostication of ALI/ARDS.

    In 1979, the department of Psychology started its activity to provide psychological support to patients and their families during the course of treatment and during the follow-up period. Since 1986, a transplantation program was initiated in the cardiology and pediatric cardiac surgery departments, performing 179 cardiac, 3 heart-kidney, 18 heart-lung 14 both lung, 1 heart-lung-liver, and 1 single lung transplantation. From 1993, to September 2010 the kidney transplant program has performed. 218 cases. Since 2008, we performed (32 liver and 1 intestinal transplantations). We examined the quality of life and coping with transplantation attitudes because there is recent evidence of high levels of family anxiety and depression related to a child's poor response to the disease and compliance. Our work associated post-traumatic stress disorder (PTSD) with anxiety and with these clinical variables: gender pathology, rejection, number of drugs frequency of hospital visits, number of hospitalizations, as well as age at and time from transplantation. We examined 56 parents (25 fathers and 31 mothers) of cardiac transplant recipients. Our most relevant data demonstrated the presence of PTSD among 52% of mothers and 40% of fathers. Significant correlations were observed within the trait of anxiety. No correlations were noted between PTSD and other variables. Testing anxiety levels of parents is considered to be basic to provide psychological support to parents, encourage personal skills, and avoid PTSD symptoms.

    Background Extracellular matrix allows lung cancer to form its shape and grow. Recent studies on organ reengineering for orthotopic transplantation have provided a new avenue for isolating purified native matrix to use for growing cells. Whether human lung cancer cells grown in a decellularized rat lung matrix would create perfusable human lung cancer nodules was tested. Methods Rat lungs were harvested and native cells were removed using sodium dodecyl sulfate and Triton X-100 in a decellularization chamber to create a decellularized rat lung matrix. Human A549, H460, or H1299 lung cancer cells were placed into the decellularized rat lung matrix and grown in a customized bioreactor with perfusion of oxygenated media for 7 to 14 days. Results Decellularized rat lung matrix showed preservation of matrix architecture devoid of all rat cells. All three human lung cancer cell lines grown in the bioreactor developed tumor nodules with intact vasculature. Moreover, the lung cancer cells developed a pattern of growth similar to the original human lung cancer. Conclusions Overall, this study shows that human lung cancer cells form perfusable tumor nodules in a customized bioreactor on a decellularized rat lung matrix created by a customized decellularization chamber. The lung cancer cells grown in the matrix had features similar to the original human lung cancer. This ex vivo model can be used potentially to gain a deeper understanding of the biologic processes involved in human lung cancer. PMID:22385822

    Transaxillary endoscopic sympathectomy of thoracic ganglia (T2-T3) has recently gained wider acceptance as the treatment of choice for palmar hyperhidrosis. It requires one-lung ventilation to facilitate the surgery. One-lung ventilation, however, is not without complications, among which acute pulmonary edema has been reported. In this case report, we present a patient with palmar hyperhidrosis complicated by glucose-6-phosphate dehydrogenase (G-6-PD) deficiency, who received bilateral endoscopic sympathectomy under alternate one-lung anesthesia, and developed acute pulmonary edema immediately after recruitment of the successive collapsed lung. The effects of hypoxemia, G-6-PD deficiency and sympathectomy might all add to the development of acute pulmonary edema secondary to reexpansion of each individual lung after alternate one-lung ventilation. The possibilities of the inferred causes are herein discussed. PMID:11152024

    Repair of injured lungs represents a longstanding therapeutic challenge. We show that human and mouse embryonic lung tissue from the canalicular stage of development (20-22 weeks of gestation for humans, and embryonic day 15-16 (E15-E16) for mouse) are enriched with progenitors residing in distinct niches. On the basis of the marked analogy to progenitor niches in bone marrow (BM), we attempted strategies similar to BM transplantation, employing sublethal radiation to vacate lung progenitor niches and to reduce stem cell competition. Intravenous infusion of a single cell suspension of canalicular lung tissue from GFP-marked mice or human fetal donors into naphthalene-injured and irradiated syngeneic or SCID mice, respectively, induced marked long-term lung chimerism. Donor type structures or 'patches' contained epithelial, mesenchymal and endothelial cells. Transplantation of differentially labeled E16 mouse lung cells indicated that these patches were probably of clonal origin from the donor. Recipients of the single cell suspension transplant exhibited marked improvement in lung compliance and tissue damping reflecting the energy dissipation in the lung tissues. Our study provides proof of concept for lung reconstitution by canalicular-stage human lung cells after preconditioning of the pulmonary niche.

    Patients with chronic renal failure (CRF) due to various mechanisms are prone to significant pulmonary comorbidities. With the improvements in renal replacement therapy (RRT), patients with CRF are now expected to live longer, and thus may develop complications in the lung from these processes. The preferred treatment of CRF is kidney transplantation and patients who are selected to undergo transplant must have a thorough preoperative pulmonary evaluation to assess pulmonary status and to determine risk of postoperative pulmonary complications. A MEDLINE®/PubMed® search was performed to identify all articles outlining the course of pre-surgical pulmonary evaluation with an emphasis on patients with CRF who have been selected for renal transplant. Literature review concluded that in addition to generic pre-surgical evaluation, renal transplant patients must also undergo a full cardiopulmonary and sleep evaluation to investigate possible existing pulmonary pathologies. Presence of any risk factor should then be aggressively managed or treated prior to surgery. PMID:25599047

    2015-08-01

    Gastroesophageal reflux (GER) can cause respiratory symptoms and may trigger, drive and/or worsen airway disorders, interstitial lung diseases and lung allograft dysfunction. Whether lifestyle changes and acid suppression alone can counter and prevent the adverse effects of GER on the respiratory tract remains unclear. Recent data suggest that antireflux surgery may be more effective in preventing lung disease progression in patients with idiopathic pulmonary fibrosis or lung transplant recipients who have evidence of allograft dysfunction associated with the presence of excessive GER. Additional research and clinical trials are needed to determine the role of GER in various lung disorders and identify which interventions are most efficacious in preventing the respiratory consequences of gastroesophageal reflux disease. In addition, measuring biomarkers that indicate that gastric refluxate has been aspirated into the lower respiratory tract (e.g., pepsin and bile acid concentrations in bronchoalveolar lavage fluid) may prove helpful in both diagnosis and therapeutic decision making.

    Objective Air-leak syndrome (ALS) is a life-threatening pulmonary complication following allogeneic bone marrow transplantation (allo-BMT) which is thought to be associated with graft-versus-host disease (GVHD). Recently, it has been reported that pleuroparenchymal fibroelastosis (PPFE) also occurs after allo-BMT and often causes ALS. We sought to extract common features of ALS caused by PPFE after allo-BMT. Methods The clinical data of patients who developed ALS caused by PPFE after undergoing allo-BMT (ALS-PPFE) between April 1996 and December 2007 at our institution were collected and reviewed retrospectively. The clinical findings, radiological and pathological features and treatment outcomes of ALS-PPFE were assessed. Results Five patients who developed ALS had histologically proven PPFE (four men, one woman: median age, 37 years). The age of onset of ALS-PPFE was 13 to 109 months (median, 68.8 months) after BMT. Alkylating agents were used as conditioning chemotherapy for BMT in all patients. Only one patient developed chronic GVHD (limited type). The common radiological findings were subpleural thickening and traction bronchiectasis predominantly in the bilateral upper lung fields. The histological pulmonary specimens showed no findings of bronchiolitis obliterans or GVHD. Immunosuppressive therapy was not effective in any of the cases, and all patients died of respiratory failure with or without lung transplantation. Conclusion ALS-PPFE is an extremely late-onset noninfectious pulmonary complication of allo-BMT. This complication is progressive, resistant to immunosuppressive treatment and has a poor prognosis. No association was found between PPFE and GVHD. PMID:26781007

    Bilateral spontaneous pneumothorax secondary to disease is rare and seldom encountered in forensic autopsies; however, traumatic bilateral pneumothorax occurs often. Herein, we present a forensic case involving a 50-year-old woman who died 4 days after ingesting a wristwatch. Postmortem computed tomography and autopsy findings demonstrated that the wristwatch was lodged at the pharyngoesophageal junction, that she had a bilateral pneumothorax unaccompanied by any thoracic wound, and that macular hemorrhagic lesions on the lung surfaces were responsible for the pneumothorax. A histological examination of the macular lesions revealed that they were aspiration pneumonia foci with many birefringent foreign materials. Furthermore, a necrotic process secondary to aspiration pneumonia with a one way check-valve hyperinflation caused by foreign materials in the bronchioles was the most probable pathogenesis of her pneumothorax. To our knowledge, this is the first reported case of a bilateral secondary spontaneous pneumothorax caused by a large foreign body at the pharyngoesophageal junction leading to death.

    The clinician should be constantly aware of the danger of aspiration in cases of prolonged sepsis with profuse suppuration. In such cases, it might be wiser to establish dependent extraoral drainage, rather than relying solely on intraoral means. The chances of aspirating septic material and the resultant occurrence of pulmonary abscesses will be lessened.

    Lung diseases such as emphysema, interstitial fibrosis, and pulmonary vascular diseases cause significant morbidity and mortality, but despite substantial mechanistic understanding, clinical management options for them are limited, with lung transplantation being implemented at end stages. However, limited donor lung availability, graft rejection, and long-term problems after transplantation are major hurdles to lung transplantation being a panacea. Bioengineering the lung is an exciting and emerging solution that has the ultimate aim of generating lung tissues and organs for transplantation. In this article we capture and review the current state of the art in lung bioengineering, from the multimodal approaches, to creating anatomically appropriate lung scaffolds that can be recellularized to eventually yield functioning, transplant-ready lungs. Strategies for decellularizing mammalian lungs to create scaffolds with native extracellular matrix components vs. de novo generation of scaffolds using biocompatible materials are discussed. Strengths vs. limitations of recellularization using different cell types of various pluripotency such as embryonic, mesenchymal, and induced pluripotent stem cells are highlighted. Current hurdles to guide future research toward achieving the clinical goal of transplantation of a bioengineered lung are discussed. PMID:26254424

    Amyotrophic neuralgia is an uncommon neuropathy characterized by severe unilateral shoulder pain. Isolated or concomitant involvement of other peripheral motor nerves depending on the brachial plexus such as phrenic or laryngeal nerves is unusual(1). Its etiology is unknown, yet several explanatory factors have been proposed. Phrenic nerve involvement, either unilateral or bilateral, is exceedingly rare. Diagnosis relies on anamnesis, functional and imaging investigations and electromyogram. We report the case of a 48-year-old woman with a past history of renal transplantation due to proliferative glomerulonephritis with subsequent transplant rejection, who was eventually diagnosed with amyotrophic neuralgia with bilateral phrenic involvement, and who required sustained non-invasive mechanical ventilation.

    2016-01-01

    Background Surgical treatment is thought to be the most effective strategy for multiple small nodules. However, in general, one-stage bilateral resection is not recommended due to its highly invasive nature. Methods Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2009 and September 2014 in a single institution were retrospectively reviewed. Results Simultaneous bilateral pulmonary resection by conventional video-assisted thoracic surgery (VATS) was undertaken in 29 patients. Ground glass opacity (GGO) accounted for 71.9% (46/64) of total lesions, including 26 pure GGO and 20 mixed GGO lesions. One case underwent bilateral lobectomy that was complicated by postoperative dyspnea. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 16 and 12 cases, respectively, and most of these cases had uneventful postoperative courses. There was no significant difference with regard to postoperative complications (P=0.703), duration of use of chest drains (P=0.485), between one- and two-stage groups. Mean postoperative follow-up in cases of primary lung cancer was 31.4 (range, 10–51) months. There was neither recurrence nor deaths at final follow-up. Conclusions Single-stage bilateral surgery in selected cases with synchronous bilateral multiple nodules (SBMNs) is feasible and associated with satisfactory outcomes. PMID:27076942

    Cytomegalovirus (CMV) is a highly complex pathogen which, despite modern prophylactic regimens, continues to affect a high proportion of thoracic organ transplant recipients. The symptomatic manifestations of CMV infection are compounded by adverse indirect effects induced by the multiple immunomodulatory actions of CMV. These include a higher risk of acute rejection, cardiac allograft vasculopathy after heart transplantation, and potentially bronchiolitis obliterans syndrome in lung transplant recipients, with a greater propensity for opportunistic secondary infections. Prophylaxis for CMV using antiviral agents (typically oral valganciclovir or intravenous ganciclovir) is now almost universal, at least in high-risk transplants (D+/R-). Even with extended prophylactic regimens, however, challenges remain. The CMV events can still occur despite antiviral prophylaxis, including late-onset infection or recurrent disease, and patients with ganciclovir-resistant CMV infection or who are intolerant to antiviral therapy require alternative strategies. The CMV immunoglobulin (CMVIG) and antiviral agents have complementary modes of action. High-titer CMVIG preparations provide passive CMV-specific immunity but also exert complex immunomodulatory properties which augment the antiviral effect of antiviral agents and offer the potential to suppress the indirect effects of CMV infection. This supplement discusses the available data concerning the immunological and clinical effects of CMVIG after heart or lung transplantation.

    Post-transplant lymphoproliferative disorder (PTLD) is a complication of allogeneic bone marrow transplantation (BMT). Rare cases of PTLD after autologous BMT have been reported only in adults. This case report is the first to describe PTLD in a pediatric patient after autologous peripheral stem cell transplantation (PSCT). This 2-year-old male with stage IV neuroblastoma underwent autologous PSCT. The post-PSCT course was complicated by fever with hematochezia and a lung mass. On day 94 post PSCT, colonoscopy revealed an ulcer due to a PTLD, monomorphic type, B cell phenotype, associated with Epstein-Barr virus. Fine needle aspiration identified the lung mass as neuroblastoma. PTLD can occur in pediatric autologous PSCT recipients, and may occur more frequently in autologous grafts manipulated by T cell depletion or CD34+ cell selection.

    A total of 59 heart transplantations (HTx) have been performed in Japan as of September, 2008, since the Organ Transplantation Law was settled in October 1997. The majority of recipients were suffered from dilated cardiomyopathy and waiting condition of all recipients were status 1. The mean waiting time was 777 day; 50 patients (85%) were supported by several types of left ventricular assist systems (LVAS) and the mean duration of support was 780 days. The majority of patients underwent operation by modified bicaval method with Celsior solution for cardiac preservation, and 64% of recipients were administered triple therapy with cyclosporine, mycophenolate mofetil, and steroid as the initial immunosuppressive regimen. The 9-year survival rate was 94%, which was superior to that of the international registry. HTx in Japan has been very limited by a severe shortage of donors, but the results have been excellent even though the majority of recipients were waiting for long-term with a LVAS as a bridge to HTx.

    2015-01-01

    Performance on a range of visual-processing tasks has been shown to improve when information is split bilaterally across the left and right visual hemifields rather than being restricted to a single visual hemifield. However, a recent study by Delvenne et al. found no such bilateral advantage for subitizing, which is our ability to rapidly and accurately enumerate small quantities of objects. This finding is particularly surprising, as it contradicts the prediction of FINgers of INSTantiation theory that subitizing should benefit from bilateral presentation. Our study investigated the issue by determining if there are any circumstances where a bilateral advantage for subitization occurs. Contrary to Delvenne et al., we found that subitizing could show bilateral advantages, but only when the display was backward-masked. We discuss these findings in relation to how the rate of encoding and the time available for this encoding may affect bilateral advantages in subitizing. A general model is proposed under which bilateral advantages could be explained.

    2008-01-01

    The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges; it has shown to be an effective image denoising technique. An important issue with the application of the bilateral filter is the selection of the filter parameters, which affect the results significantly. There are two main contributions of this paper. The first contribution is an empirical study of the optimal bilateral filter parameter selection in image denoising applications. The second contribution is an extension of the bilateral filter: multiresolution bilateral filter, where bilateral filtering is applied to the approximation (low-frequency) subbands of a signal decomposed using a wavelet filter bank. The multiresolution bilateral filter is combined with wavelet thresholding to form a new image denoising framework, which turns out to be very effective in eliminating noise in real noisy images. Experimental results with both simulated and real data are provided. PMID:19004705

    The interstitial lung diseases are a heterogeneous group of disorders characterized by inflammation and/or fibrosis of the pulmonary interstitium. In 2002, the American Thoracic Society and the European Respiratory Society revised the classification of interstitial lung diseases and introduced the term diffuse parenchymal lung disease. The idiopathic interstitial pneumonias are a subtype of diffuse parenchymal lung disease. The idiopathic interstitial pneumonias are subdivided into usual interstitial pneumonia (with its clinical counterpart idiopathic interstitial pneumonia), nonspecific interstitial pneumonia, cryptogenic organizing pneumonia, acute interstitial pneumonia, desquamative interstitial pneumonia, respiratory bronchiolitis interstitial lung disease, and lymphocytic pneumonia. Sarcoidosis and hypersensitivity pneumonitis are the 2 most common granulomatous diffuse parenchymal lung diseases. Rheumatoid arthritis, systemic sclerosis, and dermatomyositis/polymyositis (causing antisynthetase syndrome) are diffuse parenchymal lung diseases of known association because these conditions are associated with connective tissue disease. Hermansky-Pudlak syndrome is a rare genetic diffuse parenchymal lung disease characterized by the clinical triad of pulmonary disease, oculocutaneous albinism, and bleeding diathesis. This review provides an overview of the chronic fibrosing diffuse parenchymal lung diseases. Its primary objective is to illuminate the clinical challenges encountered by clinicians who manage the diffuse parenchymal lung diseases regularly and to offer potential solutions to those challenges. Treatment for the diffuse parenchymal lung diseases is limited, and for many patients with end-stage disease, lung transplantation remains the best option. Although much has been learned about the diffuse parenchymal lung diseases during the past decade, research in these diseases is urgently needed. PMID:19170214

    As a potential transplant antigen, major histocompatibility complex class I chain-related gene A (MICA) antigen, has attracted increased attention because of its possible role in solid organ transplantation. There are two MICA forms, and MICA antibodies and soluble MICA (sMICA) have been found in the serum of transplant recipients. We searched MEDLINE, EMBASE, and the Cochrane Library for original reports of clinical studies involving the effect of MICA on outcomes of renal, heart, lung, and liver transplantation. In addition to the human leukocyte antigen antigens, which elicit a strong immune response, the polymorphic MICA antigens induce production of MICA antibodies and sMICA. A number of clinical studies have shown that MICA antibodies correlate with an increased incidence of rejection and a decreased allograft survival rate following renal or heart transplantation. Although it is clearly associated with chronic rejection of lung allografts, no such correlation was found for liver transplantation. Moreover, sMICA showed a negative association with acute rejection (AR) and may be a good predictor of heart transplant outcomes. These data suggest MICA expression patterns and regulatory function may be tissue specific and that different transplants have different organ-specific outcomes.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

Our experience with transplanted organs included kidney (n=7), lung (n=3), liver (n=2) and heart (n=1). Age at HCT ranged from 2 to 56 yr. Median time between HCT and SOT was 7.9 yr (range 1.2-15.9 yr). Among the 11 patients with post-SOT follow-up information, 10 had normal function of the transplanted solid organ at the time of last contact or death. Infections and secondary malignancy were the most common complications. Four other institutional experiences with kidney transplant, 21 case reports of liver transplant, 11 case reports of lung transplant and one cardiac transplant are also summarized. SOT is feasible for selected HCT survivors with organ failure and may be associated with favorable long-term survival and graft function. More research is needed to further delineate the subset of survivors who will benefit the most from SOT with the least risk of complications.

    Depth maps are used in many applications, e.g. 3D television, stereo matching, segmentation, etc. Often, depth maps are available at a lower resolution compared to the corresponding image data. For these applications, depth maps must be upsampled to the image resolution. Recently, joint bilateral filters are proposed to upsample depth maps in a single step. In this solution, a high-resolution output depth is computed as a weighted average of surrounding low-resolution depth values, where the weight calculation depends on spatial distance function and intensity range function on the related image data. Compared to that, we present two novel ideas. Firstly, we apply anti-alias prefiltering on the high-resolution image to derive an image at the same low resolution as the input depth map. The upsample filter uses samples from both the high-resolution and the low-resolution images in the range term of the bilateral filter. Secondly, we propose to perform the upsampling in multiple stages, refining the resolution by a factor of 2×2 at each stage. We show experimental results on the consequences of the aliasing issue, and we apply our method to two use cases: a high quality ground-truth depth map and a real-time generated depth map of lower quality. For the first use case a relatively small filter footprint is applied; the second use case benefits from a substantially larger footprint. These experiments show that the dual image resolution range function alleviates the aliasing artifacts and therefore improves the temporal stability of the output depth map. On both use cases, we achieved comparable or better image quality with respect to upsampling with the joint bilateral filter in a single step. On the former use case, we feature a reduction of a factor of 5 in computational cost, whereas on the latter use case, the cost saving is a factor of 50.

    Congenital bilateral vocal cord paralysis (CBVCP) is a rare but potentially life-threatening condition and awareness of the condition is necessary to ensure early diagnosis and treatment. This case describes a 25-month-old boy suffering from CBVCP. The main symptoms at birth were inspiratory stridor combined with a normal voice and feeding problems. The difficulties in achieving the right diagnosis are demonstrated, and the treatment so far, including tracheotomy and a feeding tube, is outlined. The importance of fibre optic laryngoscopy in both diagnosis and control is stressed. PMID:19174021

    Independent bilateral primary bronchial carcinomas are not common. Since Beyreuther's description in 1924, 16 well-documented cases of independent primary bronchial carcinomas of different histology have been described. From 1965 to 1970, eight cases were seen at the London Chest Hospital. In order to make the diagnosis of a second primary bronchial carcinoma, each tumour should be malignant and neither should be a metastasis from the other. To meet this last criterion, the histopathological features of the two tumours must be different. Many cases have been described in the literature as double primary bronchial carcinomas where the second primary had the same histological features as the first. Images PMID:4327711

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

    Melatonin is an indolamine produced by the pineal gland and it can exert a potent antioxidant effect. Its free radical scavenger properties have been used to advantage in different organ transplants in animal experiments. Several concentrations and administration pathways have been tested and melatonin has shown encouraging beneficial results in many transplants of organs such as the liver, lungs, heart, pancreas, and kidneys. The objective of the present study was to review the scientific literature regarding the use of melatonin in ovary transplantation. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was carried out using the Cochrane and Pubmed databases and employing the terms 'melatonin' AND 'ovary' AND 'transplantation.' After analysis, 5 articles were extracted addressing melatonin use in ovary transplants and involving 503 animals. Melatonin enhanced various graft aspects like morphology, apoptosis, immunological reaction, revascularization, oxidative stress, and survival rate. Melatonin's antioxidative and antiapoptotic properties seemingly produce positive effects on ovarian graft activity. Despite the promising results, further studies in humans need to be conducted to consolidate its use, as ovary transplantation for fertility preservation is gradually being moved from the experimental stage to a clinical setting.

    WU polyomavirus (WUPyV) was detected in a bone marrow transplant recipient with severe acute respiratory distress syndrome who died in 2001. Crystalline lattices of polyomavirus-like particles were observed in the patient’s lung by electron microscopy. WUPyV was detected in the lung and other tissues by real-time quantitative PCR and identified in the lung and trachea by immunohistochemistry. A subset of WUPyV-positive cells in the lung had morphologic features of macrophages. Although the role of WUPyV as a human pathogen remains unclear, these results clearly demonstrate evidence for infection of respiratory tract tissues in this patient. PMID:26691850

    Chondroblastoma is a benign bone tumor with a relatively high incidence in older children and adolescents. Although it is generally regarded as a benign neoplasm, it sometimes grows aggressively or recurs but rarely metastasizes to the lung. We herein present a very rare case of a bilateral pneumothorax due to a pulmonary metastasis from a chondroblastoma. A 21-year-old man developed a bilateral pneumothorax 20 months after an operation for a chondroblastoma of the right ischium. A pertinent literature review revealed similar cases of chondroblastoma with pulmonary metastasis, but revealed no reports of a pneumothorax caused by a metastatic chondroblastoma.

  4. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    A 45-year-old man of bilateral occipital infarction with central homonymous hemianopia is reported. He was admitted to our hospital with complaints of visual loss and large central scotoma on both eyes. Pupillary light reaction and ocular fundi were normal. On admission, bilateral retrobulbar optic neuritis was suspected. However, congruous, irregular central scotomas with vertical step were observed in both eyes with Goldmann perimetry. X-ray computed tomography (CT) and magnetic resonance imaging (MRI) revealed the infarction in bilateral occipital tips. Bilateral central homonymous hemianopia is considered to be rare and a case in which occipital lobe lesions were detected with X-ray CT and MRI has not been reported. We stress that bilateral central scotomas with vertical step indicate bilateral occipital lesions.

    Kidney transplants were first performed in Tunisia in 1986, and transplants soon extended to other organs including the heart, liver, and pancreas. Live-related donor and deceased-donor kidney transplants were both began in the summer of 1986. An organ procurement and transplant law was passed in March 1991, and the National Centre for Advancement of Organ Transplantation was created in 1995. The number of transplantation units has increased to 7 throughout the country, and the yearly transplant number has progressively increased to 139 in 2010, including 20% from deceased kidney donors. Despite these gains, the need continues to grow. Heart transplants began in January 1993, and Tunisia and Jordan are currently the only Arab countries where it is practiced. However, only 16 patients have received a heart transplant as of 2004, and the number of recipients has decreased in the past 10 years. Liver transplants are rare in other Arab countries, but began in Tunisia in January 1998. Over 10 years, 38 patients benefited from this procedure. After a few years of stagnation, the number of liver transplants is increasing. While all types of transplantation are needed, kidney transplantation is a priority in Tunisia. The target is to perform 400 transplants annually, which would require a long-term strategy to provide full financial coverage using the National Health Insurance Funds in both the public and private sectors.

    Recently we described methods for optimizing the function of transplanted rat kidneys. In unilaterally nephrectomized recipients, one week after surgery, the left transplanted kidney was identical to the right native kidney with respect to wet weight and the clearances of inulin and para-aminohippuric acid (PAH). The goals of the present experiments were first, to extend the post-surgery period to three weeks (sufficient to allow hypertrophic changes), and second, to study function of transplanted hypertrophied kidneys. Genetically identical Brown Norway rats were used as donor and recipients. Three weeks after transplanting a normal kidney into a unilaterally-nephrectomized recipient, the transplanted kidney had a normal plasma flow and was identical to the contralateral native kidney with respect to wet weight and the clearances of inulin and PAH. Three weeks after transplanting a normal kidney into a bilaterally-nephrectomized recipient, the wet weight, inulin and PAH clearances, and plasma flow of the transplanted kidney were all higher than control, and not significantly different from those observed in unilaterally-nephrectomized control rats. Thus, transplanted and native kidneys exhibited the same degree of compensatory hypertrophy. Hypertrophied donor kidneys (that is, the donor rat had been unilaterally-nephrectomized three weeks previously) remained hypertrophied in bilaterally-nephrectomized recipients, but in unilaterally-nephrectomized recipients, they regressed towards normal (that is, the values of wet weight, inulin and PAH clearances and plasma flow were significantly less than those in rats with only one kidney) while the contralateral native kidney remained normal (values of wet weight and inulin and PAH clearances were not different from control).(ABSTRACT TRUNCATED AT 250 WORDS)

    Developments in transplantation have progressed dramatically over the past century. Current research is underway to optimize immune modulation, genetically engineering animals for xenografting, and breakthroughs are occurring in regenerative medicine. However, pioneering live-donor transplantation has transformed transplantation in the organ shortage, and these contribute an increased proportion of transplanted organs. Live-donor transplantation is associated with better long-term outcomes, and techniques to recover organs have become less invasive. We set out to examine the evolution of transplantation from its historic beginnings to the developments that make it successful today.

The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

    Gender as a critical, intrinsic, non-immunologic factor plays a pivotal role in the field of transplantation. The gender of donors and recipients is involved in the entire process, including organ donation and transplant surgery. This review article aims to summarize the literature related to the role of gender in solid organ donation and transplantation and to unveil the underlying mechanism by which gender mismatch between donor and recipient impacts transplant rejection. A systematic search was conducted through PubMed by using the following key words: "gender", or "sex", and "transplant", "organ donation" for published articles. The prima facie evidence demonstrated that females are more likely to donate their organs and are less willing than males to accept transplant surgery; however, their donated liver organs will have a higher risk of graft failure compared with males. With respect to kidney, heart, and lung transplantations, the role of gender remains controversial. Results of animal studies support the negative impact of gender mismatch on allograft function. In conclusion, our present study advances the knowledge of gender issues in the field of solid organ donation and transplantation. In general, gender mismatch is not advantageous to transplant outcome, as evidenced by many aspects of biological investigations on immunogenicity of H-Y antigen to females. Therefore, gender issues should be highlighted and an a priori intervention is needed to improve graft survival in clinical practice.

    OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has been a surgical intervention of choice for the treatment of spontaneous pneumothorax (SP) with lung bulla. Our objective was to introduce a uniportal VATS approach for simultaneous bilateral bullectomy and to evaluate its therapeutic efficacy. METHODS: Between May of 2011 and January of 2012, five patients underwent bilateral bullectomy conducted using this approach. All of the patients presented with bilateral SP. Preoperative HRCT revealed that all of the patients had bilateral apical bullae. We reviewed the surgical indications, surgical procedures, and outcomes. RESULTS: All of the patients were successfully submitted to this approach for bilateral bullectomy, and there were no intraoperative complications. The median time to chest tube removal was 4.2 days, and the median length of the postoperative hospital stay was 5.2 days. The median postoperative follow-up period was 11.2 months. One patient experienced recurrence of left SP three weeks after the surgery and underwent pleural abrasion. CONCLUSIONS: Bilateral bullectomy through uniportal VATS combined with contralateral access to the anterior mediastinum is technically reliable and provides favorable surgical outcomes for patients with bilateral SP who develop bilateral apical bullae. However, among other requirements, this surgical procedure demands that surgeons be experienced in VATS and that the appropriate thoracoscopic instruments are available. PMID:23503483

    To determine if the presence of bilateral implants, in addition to other anatomic and treatment-related variables, affects coverage of the target volume and dose to the heart and lung in patients receiving postmastectomy radiation therapy (PMRT). A total of 197 consecutive women with breast cancer underwent mastectomy and immediate tissue expander (TE) placement, with or without exchange for a permanent implant (PI) before radiation therapy at our center. PMRT was delivered with 2 tangential beams + supraclavicular lymph node field (50 Gy). Patients were grouped by implant number: 51% unilateral (100) and 49% bilateral (97). The planning target volume (PTV) (defined as implant + chest wall + nodes), heart, and ipsilateral lung were contoured and the following parameters were abstracted from dose-volume histogram (DVH) data: PTV D{sub 95%} > 98%, Lung V{sub 20}Gy > 30%, and Heart V{sub 25}Gy > 5%. Univariate (UVA) and multivariate analyses (MVA) were performed to determine the association of variables with these parameters. The 2 groups were well balanced for implant type and volume, internal mammary node (IMN) treatment, and laterality. In the entire cohort, 90% had PTV D{sub 95%} > 98%, indicating excellent coverage of the chest wall. Of the patients, 27% had high lung doses (V{sub 20}Gy > 30%) and 16% had high heart doses (V{sub 25}Gy > 5%). No significant factors were associated with suboptimal PTV coverage. On MVA, IMN treatment was found to be highly associated with high lung and heart doses (both p < 0.0001), but implant number was not (p = 0.54). In patients with bilateral implants, IMN treatment was the only predictor of dose to the contralateral implant (p = 0.001). In conclusion, bilateral implants do not compromise coverage of the target volume or increase lung and heart dose in patients receiving PMRT. The most important predictor of high lung and heart doses in patients with implant-based reconstruction, whether unilateral or bilateral, is treatment of

    Cytomegalovirus (CMV) infection negatively influences both short- and long-term outcomes after cardiothoracic transplantation. In heart transplantation, registry analyses have shown that CMV immunoglobulin (CMVIG) with or without virostatic prophylaxis is associated with a significant reduction in mortality and graft loss versus no prophylaxis, particularly in high-risk donor (D)+/recipient (R)- transplants. Randomized comparative trials are lacking but retrospective data suggest that addition of CMVIG to antiviral prophylaxis may reduce rates of CMV-related events after heart transplantation, including the incidence of acute rejection or chronic allograft vasculopathy. However, available data consistently indicate that when CMVIG is used, it should be administered with concomitant antiviral therapy, and that evidence concerning preemptive management with CMVIG is limited, but promising. In lung transplantation, CMVIG should again only be used with concomitant antiviral therapy. Retrospective studies have shown convincing evidence that addition of CMVIG to antiviral prophylaxis lowers CMV endpoints and mortality. The current balance of evidence suggests that CMVIG prophylaxis reduces the risk of bronchiolitis obliterans syndrome, but a controlled trial is awaited. Overall, the relatively limited current data set suggests that prophylaxis with CMVIG in combination with antiviral therapy appears effective in D+/R- heart transplant patients, whereas in lung transplantation, addition of CMVIG in recipients of a CMV-positive graft may offer an advantage in terms of CMV infection and disease.

    Summary: A successful bilateral ear composite graft nonmicrosurgical reattachment is presented. In cases where suitable vessels are unavailable for microsurgical revascularization, the reconstructive challenge can be formidable for salvaging the unique anatomic and aesthetic structure of the ear. The case is presented of an 18-year-old woman who was a victim of an assault wherein both of her ears were intentionally amputated by her attacker. She underwent successful surgical reattachment followed by a postoperative regimen of hyperbaric oxygen, cooling, and meticulous wound care. The patient achieved 100% survival of her left ear graft and 95% survival of her right ear graft. Clinical photographs at 18 months are presented, along with a discussion of the possible implications for other reconstructive applications. PMID:25289367

The first vascularized pancreas transplant was performed by William Kelly and Richard Lillehei, to treat a type 1 diabetes patient, in December 1966. In Brazil, Edison Teixeira performed the first isolated segmental pancreas transplant in 1968. Until the 1980s, pancreas transplants were restricted to a few centers of the United States and Europe. The introduction of tacrolimus and mycophenolate mofetil in 1994, led to a significant outcome improvement and consequently, an increase in pancreas transplants in several countries. According to the International Pancreas Transplant Registry, until December 31st, 2010, more than 35 thousand pancreas transplants had been performed. The one-year survival of patients and pancreatic grafts exceeds 95 and 83%, respectively. The better survival of pancreatic (86%) and renal (93%) grafts in the first year after transplantation is in the simultaneous pancreas-kidney transplant group of patients. Immunological loss in the first year after transplant for simultaneous pancreas-kidney, pancreas after kidney, and pancreas alone are 1.8, 3.7, and 6%, respectively. Pancreas transplant has 10 to 20% surgical complications requiring laparotomy. Besides enhancing quality of life, pancreatic transplant increases survival of uremic diabetic patient as compared to uremic diabetic patients on dialysis or with kidney transplantation alone.

    Two novel approaches have been developed to potentially increase the availability of donor lungs for lung transplantation. In the first approach, lungs from donation after cardiac death (DCD) donors are used to increase the quantity of organ donors. In the second approach, a newly developed normothermic ex vivo lung perfusion (EVLP) technique is used as a means of reassessing the adequacy of lung function from DCD and from high-risk brain death donors prior to transplantation. This EVLP technique can also act as a platform for the delivery of novel therapies to repair injured organs ex vivo. PMID:21511086
