[The evaluation of the efficacy of efferent therapy in patients with acute and chronic kidney failure by the spectrum of blood middle-molecule fractions].

Blood serum endotoxins were studied in patients with acute and chronic renal failure in order to correlate this spectrum with the treatment efficacy. Gel [correction of Liquid] chromatography tests of the serum samples were made in 106 patients on hemodialysis, hemodiafiltration and hemosorption. Hemodialysis was found to significantly reduce concentration of middle-mass molecular fraction (C, D, F with molecular mass from 300 to 2000 D). Hemodiafiltration produced the same effect, but more rapidly. A single procedure of hemosorption was able to improve the patients condition in the course of 2 postprocedure weeks. The authors attribute this effect to removal of the molecular fraction A which is highly toxic.
