137 patients on maintenance dialysis were studied. All but 2 patients were ambulatory, and all patients demonstrated good to normal strength on manual motor tests. With the exception of systemic lupus erythematosus, no correlation was found between primary diagnosis and patients' fatigue ratings. Laboratory studies of hematocrit, BUN, creatinine, calcium, and phosphorus did not correlate with fatigue ratings for the majority of patients. Fatigue appeared more problematic for patients who had been dialyzing for less than 4 years. Depression was pronounced among patients who reported feeling fatigued upon arising.

We examined 58 patients (38 men, 20 women; mean age: 45 +/- 12 years; body mass index: 24 +/- 4 kg/m2) with a glomerular filtration rate (GFR) ranging from 3 to 32 ml/min, in order to determine the effects of a progressive decline in renal function on total hemoglobin (THb) and exercise capacity. The THb ranged from 185 to 759 g and the hemoglobin concentration ranged from 66 to 151 g/l. Maximal exercise capacity ranged from 50 to 260 W (40-143% of the expected norm). Nearly all the patients interrupted their exercise tests due to general fatigue, leg tiredness or a combination of these factors. There was a significant partial correlation between THb and GFR after sex and age had been accounted for (r = 0.39; p < 0.005). Maximal exercise capacity and THb showed a significant partial correlation after sex, age and GFR had been accounted for (r = 0.27; p < 0.05). Maximal exercise capacity showed a significant partial correlation with GFR after sex, age and THb had been accounted for (r = 0.30; P < 0.05). In conclusion, there is a gradual decline in THb and maximal exercise capacity as uremia progresses. Anemia appears to be a contributory cause responsible for the decrease in maximal exercise capacity along with other factors pertinent to uremia per se.

A disease-specific questionnaire to assess the quality of life of renal transplant recipients was developed. A list of items of potential relevance to these patients was created and 50 transplant recipients rated the importance of each item. A combination of factor analysis and clinical judgment was then used to create the final questionnaire which consists of 25 questions in 5 dimensions (physical symptoms, fatigue, uncertainty/fear, appearance and emotions). The physical symptoms dimension is patient specific. All questions are scored on a 7-point Likert scale. The reproducibility of the questionnaire when it was administered to stable transplant recipients was high (intraclass correlation coefficients between 0.82 and 0.91 for the 5 dimensions). The scores of all dimensions except appearance improved 6 months after transplantation, when compared to pretransplantation scores. Patients who had a well-functioning graft (creatinine < 250 mmol/l) had higher scores than those with poorly functioning grafts. This questionnaire is easy to administer and is valid, reproducible in stable patients and responsive to change.

A case of a renal transplant recipient with colchicine-induced myopathy is presented. He was on colchicine therapy for 10 months. He was hospitalized for investigation of fatigue, severe myalgia in the lower extremities and elevated serum aminotransferase levels. His viral markers and other factors that may cause myalgia and that may increase the serum aminotransferase levels were either normal or negative. Creatine phosphokinase (CK) levels were normal. Electrophysiological findings indicated myopathy and muscle biopsy was consistent with vacuolar myopathy. After withdrawal of colchicine, the symptoms disappeared gradually and serum aminotransferase levels were normalized. We suggest that colchicine myopathy should be taken into account in patients who have been on colchicine therapy and had unexplained myalgia as well as elevated aminotransferase levels even with normal CK levels.

Patients with advanced chronic kidney disease (CKD), especially those on long-term dialysis, often suffer from muscle wasting and excessive fatigue. It is known that inactivity, muscle wasting and reduced physical functioning are associated with increased mortality in CKD. Known causes include uraemic myopathy and neuropathy, inactivity, and anaemia. Exercise in patients receiving regular dialysis treatment for end-stage renal disease was first introduced 3 decades ago, but is still only offered in a minority of renal units around the world, despite a significant body of evidence to support its use. Work is needed to increase awareness of the potential benefits of increased physical activity for patients with advanced CKD. This review summarizes the mechanisms of exercise intolerance and debility in advanced CKD patients, the methods used for the estimation of functional capacity, the options currently available for exercise training, and their influence on the well-being of this group of patients.
