End-of-life care in a COPD patient awaiting lung transplantation: a case report.

COPD is nowadays the main indication for lung transplantation. In appropriately selected patients with end stage COPD, lung transplantation may improve quality of life and prognosis of survival. However, patients with end stage COPD may die while waiting for lung transplantation. Palliative care is important to address the needs of patients with end stage COPD. This case report shows that in a patient with end stage COPD listed for lung transplantation offering palliative care and curative-restorative care concurrently may be problematic. If the requirements to remain a transplantation candidate need to be met, the possibilities for palliative care may be limited. Discussing the possibilities of palliative care and the patient's treatment preferences is necessary to prevent that end-of-life care needs of COPD patients dying while listed for lung transplantation are not optimally addressed. The patient's end-of-life care preferences may ask for a clear distinction between the period in which palliative and curative-restorative care are offered concurrently and the end-of-life care period. This may be necessary to allow a patient to spend the last stage of life according to his or her wishes, even when this implicates that lung transplantation is not possible anymore and the patient will die because of end stage COPD.

A patient-centred interdisciplinary palliative care programme for end-stage chronic respiratory diseases.

Palliative care should be part of integrated care for patients with end-stage respiratory diseases. An intensive inpatient interdisciplinary palliative care programme has been developed for patients with end-stage respiratory diseases in the Netherlands. This programme consists of the management of daily symptoms and care needs to support patients and their families, and maintain or improve quality of life of these patients and their loved ones. This article presents case studies which describe the clinical course and management of three patients admitted to the programme: a 77-year-old woman who died from chronic obstructive pulmonary disease (COPD); a 60-year-old woman with end-stage COPD who improved her daily functioning and was discharged home after 3 months; and a 74-year-old woman who died of pulmonary fibrosis. This article describes the characteristics of the programme and shows the possible benefits of an intensive patient-centred interdisciplinary palliative care programme for patients with end-stage respiratory diseases. Palliative care programmes can be the final step in the chain of care for patients with respiratory diseases. Further research is necessary to study whether, and to what extent, a patient-centred interdisciplinary palliative care programme for end-stage respiratory diseases may improve health status, daily symptom burden, patient satisfaction and quality of dying.

The functional, metabolic, and anabolic responses to exercise training in renal transplant and hemodialysis patients.

BACKGROUND: Exercise intolerance is common in hemodialysis (HD) and renal transplant (RTx) patients and is related to muscle weakness. Its pathogenesis may vary between these groups leading to a different response to exercise. The aim of the study was to compare intrinsic muscular parameters between HD and RTx patients and controls, and to assess the response to exercise training on exercise capacity and muscular structure and function in these groups. METHODS: Quadriceps function (isokinetic dynamometry), body composition (dual-energy x-ray absorptiometry), and vastus lateralis muscle biopsies were analyzed before and after a 12-week lasting training-program in 35 RTx patients, 16 HD patients, and 21 healthy controls. RESULTS: At baseline, myosin heavy chain (MyHC) isoform composition and enzyme activities were not different between the groups. VO2peak and muscle strength improved significantly and comparably over the training-period in RTx, HD patients and controls (p(time)<0.05). The proportion of MyHC type I isoforms decreased (p(time)<0.001) and type IIa MyHC isoforms increased (p(time)<0.05). The 3-hydroxyacyl-CoA-dehydrogenase activity increased (p(time)=0.052). Intrinsic muscular changes were not significantly different between groups. In the HD group, changes in lean body mass were significantly related to changes in muscle insulin-like growth factor (IGF)-II and IGF binding protein-3. CONCLUSIONS: Abnormalities in metabolic enzyme activities or muscle fiber redistribution do not appear to be involved in muscle dysfunction in RTx and HD patients. Exercise training has comparable beneficial effects on functional and intrinsic muscular parameters in RTx patients, HD patients, and controls. In HD patients, the anabolic response to exercise training is related to changes in the muscle IGF system.

Extra-pulmonary features in COPD patients entering rehabilitation after stratification for MRC dyspnea grade.

Experts have stated that referral for rehabilitation of patients with chronic obstructive pulmonary disease (COPD) becomes appropriate when these patients become aware of their disability (e.g. usually grade 3 to 5 on the Medical Research Council (MRC) dyspnea scale). However, patients with MRC dyspnea grade 1/2 may also suffer from extra-pulmonary features, such as abnormal body composition, exercise intolerance and reduced disease-specific health status. In the present study, we have studied whether and to what extent chronic obstructive pulmonary disease (COPD) patients with MRC dyspnea grade 1/2 have extra-pulmonary features compared to patients with grade 3, 4 or 5? Pulmonary function, body composition, 6-min walking distance, peak exercise capacity, anxiety, depression and disease-specific health status have been assessed in 333 outpatients who had been referred for pulmonary rehabilitation. On average, patients with MRC dyspnea grade 1/2 had a better exercise tolerance and disease-specific health status compared to patients with grade 4 or 5. Nevertheless, grade 1/2 patients had a higher prevalence of muscle mass depletion. In addition, these patients did still have aberrant values in one or more of the aforementioned outcomes. On average, patients with MRC dyspnea grade 1/2 may clearly suffer from extra-pulmonary features, indicating the necessity to refer these patients for rehabilitation. Therefore, MRC dyspnea scale alone does not appear to be a suitable measure to identify most patients with COPD who have to be referred for rehabilitation.

Similarities in skeletal muscle strength and exercise capacity between renal transplant and hemodialysis patients.

Exercise intolerance is common in hemodialysis (HD) and renal transplant (RTx) patients. Aim of the study was to assess to what extent exercise capacity and skeletal muscle strength of RTx patients differ from HD patients and healthy controls and to elucidate potential determinants of exercise capacity in RTx patients. Exercise capacity, muscle strength, lean body mass (LBM) and physical activity level (PAL) were measured by cycle-ergometry, isokinetic dynamometry, DEXA and Baecke Questionnaire, respectively, in 35 RTx, 16 HD and 21 controls. VO2peak and muscle strength of the RTx patients were significantly lower compared to controls (p<0.01), but not different compared to HD patients. In RTx patients, strength (p<0.001), PAL (p=0.001) and age (p=0.045) were significant predictors of VO2peak. Muscle strength was related to LBM (p=0.001) and age (p=0.001), whereas gender (p<0.001) and renal function (p=0.01) turned out to be significant predictors of LBM. No effects of corticosteroids were observed. Exercise capacity and muscle strength seem equally reduced in RTx and HD patients compared to controls. In RTx patients, muscle strength and PAL are highly related to exercise capacity. Renal function appears to be a significant predictor of LBM, and through the LBM, of muscle strength and exercise capacity.
