[Middle-molecule oligopeptide kinetics during intermittent hemofiltration in patients with acute kidney failure].

[Article in Russian]

Abstract

Acute renal failure was treated by intermittent hemofiltration in 19 patients (8 males and 11 females), 13 of which survived and 6 died. All of them underwent examinations for kinetics and clearance of middle-mass oligopeptides (MMOP) performed by gel filtration (sephadex G-15) and densitometry in UV light (280 nm) using C phi-24 device. Plasma levels of oligopeptides in acute renal failure were found increased 20-fold. They consisted mainly of MMOP (1000-3000 D) entering the 13th eluate fraction. There appeared a correlation between oligopeptides and creatinine plasma levels. Under hemofiltration lasting for 6.45 hours and replacing approximately total body fluid, nearly all the baseline extracellular oligopeptide pool was removed. The average rate of the filtration reached 127 ml/min, clearance of oligopeptides being 57.9 ml/min or more than 22 1 of fluid per one procedure. Intermittent hemofiltration went in enhanced (8-fold) MMOP generation responsible for residual high levels of them in plasma after the procedure.
