Diagnostic use of an analysis of urinary proteins by a practicable sodium dodecyl sulfate-electrophoresis method and rapid two-dimensional electrophoresis.

Two methods suitable for routine clinical analyses of urinary proteins are presented and compared. The first is a horizontal sodium dodecyl sulfate-polyacrylamide gel electrophoresis technique, suitable for simultaneous analysis of 20 native urinary samples. This method uses polyacrylamide gradient gels, prepared with a laboratory-built gel casting device. The second method is a rapid two-dimensional electrophoresis procedure, combining cellulose acetate electrophoresis and sodium dodecyl sulfate-electrophoresis. The first step uses a routine system (Chemetron), the second separation step followed by staining with Coomassie Brilliant Blue R is performed on the PhastSystem. The resulting two-dimensional patterns reveal urinary proteins distributed according to the 5-zone pattern of native proteins (albumin, alpha-1, alpha-2, beta, gamma-globulin) as well as to the logarithm of their molecular weights. Examples of (routine) diagnoses with a special interest in the monitoring of kidney transplant patients are shown.

Effect of renal transplantation on uremic deafness: a long-term study.

In order to investigate the influence of a functioning transplant on uremic hearing loss, audiometrical controls were performed on 13 patients before and after renal transplantation. During renal dialysis treatment there was a marked hearing loss for the higher frequencies between 2 000 and 8 000 Hz. Hearing capacity improved to normal after transplantation, the best audiometric results being obtained 21.4 (8-42) months after surgery. There was a significant improvement in hearing especially for middle- and high-tone frequencies. It is assumed that uremic toxins, possibly responsible for sensorineural hearing loss in patients with chronic renal failure may be sufficiently removed by a functioning transplant.
