title: Nerve conduction velocities and hair concentrations of trace elements in haemodialysis patients.
abstract: Nerve conduction velocities and hair concentrations of trace elements were studied in 19 male patients with chronic renal failure undergoing haemodialysis. Both motor and sensory nerve conduction velocities were significantly lower in haemodialysis patients as compared to controls (p < 0.001). Calcium and aluminium concentrations were significantly higher in patients (p < 0.01), however, vanadium and arsenic levels were significantly lower in patients (p < 0.01). In concentrations of copper and zinc there was no significant difference between patients and controls. There were no significant correlations between hair concentrations of trace elements and nerve conduction velocities except between calcium concentration and sensory nerve conduction velocity. These facts suggest that nerve conduction velocities are not influenced by changes of trace element concentrations in hair in patients with chronic renal failure undergoing haemodialysis.
