[The microvascular bed of the nail matrix in patients with chronic uremia]

The microvascular bed of the nail matrix was studied in 118 patients with chronic uremia and 25 healthy persons. It was revealed that in chronic renal failure due to chronic nephritis, the changes in microcirculation were more pronounced. Prolonged arterial hypertension led to a graver derangement of the vascular sector of the microcirculatory bed. Red blood cell aggregation depended on the stage of uremia, anemia and impairment of water-electrolyte metabolism. The data obtained on biomicroscopy of the eyeball conjunctiva correlated with the data on capillaroscopy of the nail matrix. The latter technique makes it possible to control the disease and efficacy of the treatment.
