title: [Uremic polyneuropathy in patients treated conservatively (nondialyzed) or treated with dialysis].
abstract: Uremic polyneuropathy is a common complication in dialyzed patients (pts). In 37 end stage renal disease (ESRD) pts the electroneurophysiological (ENF) parameters and serum creatinine (Pcr), guanidino compounds (GC) and guanidinosuccinic acid (GSA) levels were studied. There were 21 nondialyzed (ND), 10-hemodialyzed (HD) and 6-intermittently peritoneally dialyzed (IPD) pts. The following ENF parameters on both upper extremities, using method described by Buchtal and Rosenfalck, were performed: sensory nerves (nn.) conduction velocity, amplitude of evoked potential, subjective and objective impulse and motor nerve-conduction velocity. Cr level in serum was measured by enzymatic method, GC-by Rosenberg, Ennor, Morison method, modified by Szczepkowska. GSA isolation was performed by column chromatography. The results indicated disturbances in peripheral nn. function in all studied groups of pts and did not correlate with levels of uremic toxins in serum. However, it does not mean, that sum of the accumulated various toxic metabolites in ESRD pts, does not influence the development of polyneuropathy. The degree of impairment of peripheral nn. conduction in ESRD did not differ significantly between ND and HD or IPD pts. We did not notice, any significant differences in the degree of polyneuropathy in HD or IPD pts.
