Filter by:Pulmonary Arterial Hypertension has gone from a disease that causes rapid death to a more chronic condition. Yet, improved survival is associated with major challenges for clinicians as most patients remain with poor quality of life and limited exercise capacity. The effects of exercise training on exercise capacity have been largely evaluated and showed an improvement in 6-minutes walking distance (6MWD), peak V'O2. It is also known that exercise program improves quality of life. Maximal volitional and nonvolitional strength of the quadriceps are reduced in patients with Pulmonary Arterial Hypertension and correlated to exercise capacity. Moreover, on the cellular level, alterations are observed in both the respiratory as well as the peripheral muscles. Muscle fiber size has been reported to be decreased in some studies or conversely unaltered in human and animal models. Reduction in type I fibers and a more anaerobic energy metabolism has also been reported, but not in all studies. Likewise, a loss in capillary density in quadriceps of patients with Pulmonary Arterial Hypertension and rats has been reported, but could not be confirmed in other studies. While the impact of exercise training on clinical outcomes such as exercise capacity or quality of life is well known, this data highlight the fact that the underlying causes of peripheral muscle weakness as well as the mechanisms underlying the clinical improvements observed with exercise programs are not completely understood. Improvement of muscle cell metabolism in part via the enhancement of oxidative cellular metabolism and decrease in intracellular lipid accumulation may play a role in improving muscle function and exercise capacity. In this study, we intend to evaluate the impact of a 12 weeks home-based rehabilitation program on peripheral muscle function and metabolism, focusing on lipid infiltration, oxidative metabolism and epigenetic factors that can be involved in metabolic syndrome, in patients with Pulmonary Arterial Hypertension.
Lung or combined heart-lung transplantation represents an established treatment strategy for patients with end-stage lung disease. Transplantation results in an increased exercise capacity, a better quality of life and - depending on the pulmonary disease - a prolonged life compared to the natural course of the pulmonary disease. However, even after successful organ transplantation, patients realise the often inflated, unrealistic character of their previous expectations due to their continuing dependence on medication, regular control examinations and a higher risk of infections and allograft rejections. Patients have to cope with erupting demands in family, social and work life. It becomes evident that their lives have changed forever. In this context, limitations in mental health like depression and reduced quality of life (QoL) as well as diminished compliance may emerge or even persist. By five years post-transplant, about one-half of the patients meet the criteria of an anxiety disorder. Symptoms of a clinically relevant depression or mood disorder occur in 10 to 15 % of lung transplant patients. In addition, patients after lung transplantation are often in a poor physical condition and only hold a reduced functional status. Surgery itself, a prolonged weaning period during mechanical ventilation, sepsis, and especially the immunosuppressive medication may long-ranging or permanently limit physical activity, further reducing muscle mass and bodily function. Some positive effects of either psychological coping skills training or supervised exercise therapy after lung or heart-lung transplantation on QoL and functional status have been described in very few existing pilot studies with small numbers of patients and only short-term follow-up. In addition, although clear evidence points to a mutual amplifying effect of both psychological training and exercise therapy in patients coping with chronic disease, no such study has yet been conducted in the transplantation field. Therefore, the aim of the investigators randomised controlled study is to prove the differential benefit of a multi-modal resource-activating behavioural training programme combined with an intensified exercise training programme on functional status as well as on QoL in a four-armed design. The investigators hypotheses are: (H1) The multimodal resource-activating behavioural training programme will show better out-comes in the measures of global health-related QoL compared to a relaxation group. (H2) Participants in the intensified anaerobic exercise training will have better outcomes in the measures of exercise-related variables and lung function than the group with moderate aerobic exercise training. (H3) Participants in the behavioural intervention programme and the intensified exercise training will have better outcomes in the measures of global health-related QoL and exercise-related variables compared to the other groups.
