Conservative treatment implies procedures which involve normalization or improvement of metabolic disorders in chronic renal insufficiency and failure by medicamentous and dietary means. Keto amino acids administration can remarkable influence protein synthesis, metabolic acidosis, Ca-P and PTH levels, carbohydrate and lipid disorders, but has no effect on hyperfiltration. Long-term co-administration of rHuEPO and keto amino acids in CRF patients on LPD has accelerated metabolic effect associated with a delay in progression of renal failure and reduction of proteinuria. Also, concomitant administration of ACE inhibitors and angiotensin II AT1 receptor antagonist in CRF patients on LPD with KA was associated with significant decrease of proteinuria, amino-aciduria and, via its glomerulo-tubular action, it had also an effect on progression of CRF.
