[Hyperfiltration as a factor in the progression of chronic kidney diseases].
As many as 34 patients with nephrotic syndrome (NS) and 42 patients suffering from type I diabetes mellitus without clinical manifestations of renal damage were examined for clinical and morphological signs of hyperperfusion renal damage (hyperfiltration, microalbuminuria, specific morphological alterations). The lack of renal functional reserves was regarded as a criterion for the status of hyperfiltration (oral protein administration, intravenous injection of small doses of dopamine). The risk of the progression of renal failure by the hemodynamic type in NS amounted to 65%. In the mechanism of the development of hyperfiltration in NS, the role of systemic hypertension, renal failure, a reduction of the ultrafiltration coefficient is discussed. Hypooncia does not make any material contribution to the development of hyperfiltration in NS. The clinical and morphological signs of hyperfusion renal injury were revealed in 50% of patients suffering from type I diabetes mellitus without the clinical signs of renal injury.
