[The recovery of the kidney filtration functional reserve in diabetes mellitus patients on captopril treatment].
Overall 42 normotensive patients suffering from type I diabetes mellitus without proteinuria were examined for the effect of hyperfiltration on renal glomerular function and for changes in glomerular function seen during medicamentous treatment of hyperfiltration. Glomerular function was evaluated from the basal level of glomerular filtration (GF), the status of filtration reserves (i. e. according to the dynamics of the GF level in response to oral protein administration), and from the magnitude of albuminuria. Three groups of diabetes mellitus patients were distinguished: with filtration reserves, with decreased filtration reserves, and with no reserves. All the three groups did not differ in the age, diabetes standing or the degree of carbohydrate disorders compensation (HBA1c). Still, the patients with no filtration reserves significantly differ from the other groups with a high level of GF and albuminuria. In 9 patients, a study was made of the effect produced by captopril (an inhibitor of the angiotensin-transforming enzyme) on filtration reserves and albuminuria. After 3 to 6 months of the treatment five patients with no filtration reserves manifested a fall of the basal level of GF down to normal, the recovery of filtration reserves, and a decline of albuminuria. It is assumed that elimination of hyperfiltration due to the treatment with the inhibitors of the angiotensin-transforming enzyme may be an effective means of diabetic nephropathy prevention.
