Serum magnesium and nerve conduction velocity in uraemic patients on chronic haemodialysis.
In 18 patients on regular haemodialysis treatment, the dialysate magnesium concentration (dMg) was lowered (from 0.5 to 0.25 mmol/litre) and the correlation between serum Mg level (sMg) and nerve conduction velocity was investigated before and one year after dMg variation, in order to ascertain whether hypermagnesaemia plays a role in the pathogenesis of peripheral neuropathy in patients on regular dialysis. The normalization of sMg (from 1.27 +/- SD 0.16 to 0.98 +/- 0.09 mmol/litre) did not result in any improvement in nerve conduction velocity, though such improvement has previously been reported; however, this discrepancy could be explained by the fact that sMg was not excessively high at the beginning of the study.
