Filter by:Lung Transplantation is usually the last option for patients with chronic respiratory conditions in the late stages of the disease. Pulmonary rehabilitation and, particularly, endurance training, is a cornerstone in the management of these patients both during the pre-operative as well as the post-operative period as it improves cardiopulmonary fitness, muscle mass, muscle strength, health-related quality of life and potentially, survival. However, very few studies have been published addressing which modality of training, intensity, frequency or duration of training provides the best possible results in these patients. Therefore, the objective of this study was to compare two training modalities (treadmill walking versus cycle-ergometry) on functional capacity, muscle strength and lung function.
Estimated costs, from thirty days prior to lung transplant up through six months post surgery, exceed 1 million dollars per patient and routine medical costs average approximately fifty thousand dollars per year thereafter. Prior to transplant, lung transplant recipients self restrict activity due to severe respiratory limitations, resulting in reduced muscle mass and qualitative changes in large skeletal muscles. After transplant, despite improved lung function, studies consistently report that lung recipients fail to reach predicted physical function and physical activity. Nearly seventy percent are at risk of developing hypertension within the first five years due to side effects of immunosuppression and an inactive lifestyle worsens this risk. Consequently, full benefits of transplant may not be achieved. Few studies have tested ways to engage lung recipients in self management of exercise and adopt an active lifestyle. Lung Transplant Go LTGO is a behavioral exercise intervention that provides individualized exercise training integrated with behavioral coaching delivered in the recipient's home. Exercise training will focus on assisting lung recipients to learn and practice exercises to reverse muscle conditioning. Behavioral coaching will assist them to develop the skills to self manage physical activity in daily life and maintain this as a sustained habit using strategies that include incremental goal setting, self-monitoring, feedback and problem solving.
A controlled randomized, open-label, multi-centre study evaluating if an immunosuppressive protocol, based on ATG-induction, once daily tacrolimus-dose (Advagraf®), mycophenolate mofetil and corticosteroid reduces the incidence of chronic lung allograft dysfunction (CLAD) after lung transplantation, in comparison with a standard cyclosporin-based protocol.
Parts A & B: Conversion of stable pediatric allograft recipients from Prograf® immunosuppression to Advagraf® immunosuppression to compare exposure and one year follow-up for safety and efficacy. Part C: Continuation of long-term follow-up and provision of ongoing study medication to subjects to whom Advagraf® is currently not available.
Obliterative Bronchiolitis (OB) is the major cause of long-term lung allograft loss for patients with end stage pulmonary diseases like cystic fibrosis. Numerous cells and proteins are implicated in this process, which have never been studied prospectively in a multicentric longitudinal cohort. The aim of this study is to detect predictive risk factors of OB through a national multicentric cohort of 500 newly transplanted recipients (COLT). COLT will consist in a large database, associated with a recipient bio-collection, and specific projects using these resources. COLT will aggregate all the 11 French centres of pulmonary transplantation. Patient will be followed-up during 5 years. Blood samples will be obtained. Induced sputum, bronchoalveolar lavage fuid, exhaled breath condensate and trans bronchial biopsies will be also taken. T cells, known to be involved in chronic rejection will be studied, and genomic, microarray and proteomic approaches will be used to detect further predictive factors. A study on Circulating Endothelial Cells and Circulating Endothelial Progenitors is also realised from blood samples. COLT will prove molecular markers to be predictive of early OB, before the development of severe airway obstruction and will allow the identification of patients at high risk of OB. COLT will identify potential targets for future treatments of OB. This collaborative project makes research and clinical teams working together, and creates the conditions of a long term network, extendable to other laboratories with new projects and additional European transplant centres.
The purposes of the study are (1) to analyze the baseline patient characteristics cross-sectionally, (2) to analyze the prognosis and its predictive factors and (3) to examine the longitudinal clinical course in the lung transplant candidates in Japan.
A prospective, interventional rehabilitation program was initiated to improve exercise capacity and psychosocial functioning in patients after lung transplantation (LTx) and to evaluate long-term effects on health-related quality of life (HRQoL). Study subjects were randomized to either intervention or to control group and were followed with regular cardiopulmonary exercise testings and HRQoL measurements (SF-36) for 36±3 months after LTx. Patient characteristics did not differ concerning age, gender, and diagnosis at study entry. IG patients received regular psychosocial support and performed a home-based supervised ergometer training program. CG patients were recommended to perform regular exercising.
