Symptoms were evaluated in 13 haemodialysis patients at dialysate temperatures between 37 and 35 degrees C. After a control period at 37 degrees C (stage 1) dialysate flow rate was increased from 300 ml/min in half the patients but no change in temperature was made (stage 2). In stage 3 dialysate temperature was reduced to 36.5 degrees C and in stage 4 to 35 degrees C. Blood pressure and temperature were measured pre- and post dialysis and patient completed a questionnaire indicating if they experienced any of nine specified symptoms: itch, restless legs, nausea, vomiting, headache, cramp, lethargy, hypotension and change in temperature. Trial stages were compared with chi 2 analysis using Yates correction. Symptoms per dialysis fell from 1.11 to 0.71 between stage 1 and 2 (p less than 0.0005). This was considered to be a trial effect. There was no further significant improvement in symptoms overall as the temperature was reduced to 35 degrees C. However, if complaints of coldness are excluded, there was a progressive reduction in symptoms from stage 1 to stage 4. Dialysate flow rate did not affect symptom reporting. There was no effect on body core temperature or blood pressure due to cool dialysate. Our results suggest there may be some benefit in lowering the dialysate temperature but this is small in relation to the placebo effect. Caution must be used in assessing similar studies using small numbers of dialyses.

Restless legs syndrome (RLS) is a common entity affecting hemodialysis patients. Although the cause of RLS remains unclear, a number of therapies have been used successfully to treat the disorder. Gabapentin is an anticonvulsant shown to alleviate symptoms of RLS in two small studies of nonhemodialysis patients. Because it is excreted renally, gabapentin has a long half-life among hemodialysis patients and may be advantageous if proven effective. We conducted a randomized, double-blind, placebo-crossover study of gabapentin in the treatment of RLS among a population of hemodialysis patients. Sixteen patients identified with RLS were randomized to either gabapentin or placebo. After 6 weeks of treatment with 200 to 300 mg of gabapentin after each hemodialysis session, patients' RLS was reassessed. After a 1-week washout period, patients were switched from gabapentin to placebo or placebo to gabapentin. After another 6 weeks, patients' RLS was assessed again. Patient data were analyzed using both parametric and nonparametric means. Thirteen of the 16 original patients completed the study. Two patients dropped out because of lethargy (believed to be secondary to gabapentin), and 1 patient died secondary to myocardial infarction. Eleven patients responded to gabapentin, but not placebo (P < 0.01). One patient responded to both, and 1 patient responded to placebo, but not gabapentin. Gabapentin is an effective treatment for RLS in hemodialysis patients.

The patient was a 44-yr-old man with end-stage renal disease who had developed chorea as a result of hypoglycemic injury to the basal ganglia and thalamus and who was subsequently diagnosed with depression and restless legs syndrome (RLS). For proper management, the presence of a complex medical condition including two contrasting diseases, chorea and RLS, had to be considered. Tramadol improved the pain and dysesthetic restlessness in his feet and legs, and this was gradually followed by improvements in his depressed mood, insomnia, lethargy, and feelings of hopelessness. This case suggests that the dopaminergic system participates intricately with the opioid, serotoninergic, and noradrenergic systems in the pathophysiology of RLS and pain and indirectly of depression and insomnia.
