[The morphological characteristics of the erythrocytes during hemosorption in patients with chronic kidney failure and suppurative intoxication].

Red blood cells obtained shortly before and after a hemosorption session from 12 patients were studied in scanning electron microscope. The patients suffered from chronic renal failure and purulent intoxication consequent to urolithiasis and purulent pyelonephritis (10 cases), renal arteriosclerosis (1 case) and prostatic cancer (1 case). Before hemosorption number of discocytes measured 50.8%, while that of stomatocytes 37.3%. Spherocytes, echinocytes and knisocytes occurred in larger quantities. After hemosorption diskocytes amounted 67%, echinocytes and acanthocytes levels rose. The changes may be due to normalization of blood biochemistry after the hemosorption, and to sorbent effects on red cells.
