[Study of vibration sensation in the aspect of disorders of calcium-phosphate metabolism in patients with chronic renal failure].
A group of 72 patients with chronic renal failure (22 non-dialysed and 50 hemodialysed) were studied for the behaviour of the threshold of vibratory sensibility in upper and lower limbs at frequencies of 125 and 250 Hz. The patients dialysed were examined just before hemodialysis. All the patients were studied for the following parameters: concentration of calcium, inorganic phosphates, PTH, creatinine, uric acid in the blood serum and the activity of general alkaline phosphatase and its thermolabile fraction (osseous). The patients dialysed differed from the patients non-dialysed in higher creatinine, uricemia and the activity of alkaline phosphatase, both general and its "osseous" fraction. But they did not differ significantly in the concentration of phosphates, PTH and calcemia . Two thirds of patients with chronic renal failure, both dialysed and non-dialysed, revealed a significant increase in the threshold of vibratory sensibility, better marked in lower limbs then in upper limbs. As opposed to patients non-dialysed, patients dialysed did not show a significant correlation between the level of PTH in blood serum and the threshold of vibratory sensibility. Dialysotherapy did not influence significantly the frequency of disorders in vibratory sensibility. Considering the fact of almost identical frequency of disorders in vibratory sensibility both in patients dialysed and non-dialysed and also the lack of correlation between the level of lesion of vibratory sensibility and the concentration of PTH in blood serum, the participation of parathormone in the pathogenesis of uremic neuropathy seems to be doubtful.
