Background/Aim. Inflammation is the most important factor in the genesis of vascular complication in the endstage renal disease. The serum C-reactive protein (CRP) level is a sensitive marker of systemic inflammation as well as a predisposing factor for cardiovascular and all cause mortality in patients on hemodialysis. Albumin is the negative acute phase protein and its synthesis declines during the inflammation. The patients undergoing hemodialysis have a high prevalence of protein-energy

The low serum albumin levels in these patients originate from the complex setting of conditions with systemic inflammatory response as a major cause, malnutrition and overhydratation. The aim of this study was to determine the prevalence of elevated CRP levels in the dialysis patients and to analyse its correlation with serum albumin levels and other parameters of nutritional status. Methods. The study included 49 patients on maintenance hemodialysis at the Department of Hemodialysis, Clinic of Nephrology, Military Medical Academy, Belgrade, Serbia. In order to analyse the parameters, the blood samples were taken during the arteriovenous fistula (AVF) puncture and before the second weekly dialyse. The following parameters were determined: serum levels of urea and creatinine before and after the dialysis procedure, CRP, hemoglobin, fasting glycemia, total choles-Key words: albumins; c-reactive protein; inflammation; nutritional status; renal dialysis. Apstrakt Uvod/Cilj. Inflamacija je jedan od glavnih faktora odgovornih za nastanak vaskularnih komplikacija kod bolesnika sa terminalnom bubrežnom insuficijencijom. C reaktivni protein (CRP) se smatra senzitivnim markerom sistemske inflamacije, kao i faktorom koji doprinosi povećanom riziku od opšteg i kardiovaskularnog mortaliteta. Albumin je negativni protein akutne faze zapaljenja i njegova sinteza opada sa napredovanjem sistemske inflamacije. Za bolesnike na hemodijalizi poznato je da pate od visokog stepena proteinske malnutricije usled smanjene sinteze proteina i njihove pojačane razgradnje. Nizak nivo se-
