title: [Blood plasma amino acids and total protein, their elimination and catabolism during the hemofiltration of patients with acute kidney failure].
abstract: Intermittent hemofiltration (HF) was applied to the treatment of 8 patients (3 men and 5 women) with the grave pattern of acute renal failure (ARF) of prerenal origin. Altogether 23 sessions (from one to six in every patient) were performed with replacement of 44.3 +/- 2.8 1 liquid on the average. Two patients died. Of these, one female patient died from progressive peritonitis and sepsis and the other one from cisplatinum intoxication, bone marrow aplasia and sepsis. The content of blood plasma amino acids (AA), total protein and its fractions was measured before and after HF. Measurements were also made of excretion of those substances with filtrate. Besides, the amount of protein AA catabolized during the procedure was calculated according to the kinetics of urea. The authors hold that ARF-associated changes in the content of AA are primarily determined by adaptive shifts in metabolism. Differences in AA consumption were revealed to depend on the period and quality of adaptation. On the average HF brought about losses of 7.5 g AA and 73.1 g protein with filtrate. At the same time 37.5 g AA underwent oxidation, while urea generation rose 2-fold, amounting to 0.48 mmol/kg bw per hour. It is concluded that in ARF patients undergoing intermittent HF, it is necessary that anabolizing glucose and insulin therapy be applied together with replacement infusion of AA and (or) protein.
