[Arterial hypertension in renal amyloidosis (a clinico-morphological analysis)].

The incidence of arterial hypertension (AH) in patients with renal amyloidosis varied with its stage. Thus, AH was encountered in 13% of cases with renal amyloidosis at the proteinuric stage, 15% of those at the nephrotic stage, and 53% of those at the azotemic stage. One determinant of AH at the first two of these stages appears to have been damage to the antihypertensive system of the renal medulla, while the increased rate of AH at the azotemic stage was found to be associated with sodium retention in the body.

[Kidney function of amyloidosis patients studied by radioisotope renography using 131I-hippuran].

Radionuclide roentgenography with 131I-hippuran was performed in 53 patients with various clinical variants and stages of amyloidosis. It showed disorders of renal function even at the initial stages of disease. X-ray findings depended on a stage of amyloid nephropathy and concomitant hypertensive syndrome.
