C-reactive protein (CRP) is one of the positive proteins in an acute phase. It is produced in hepatocytes in response to cytokines activity, especially to IL-6. Its increase is the second biggest after significant bacterial and cardiovascular insults. It reaches its peak between 24 and 48 hours. CRP monitoring makes possible monitoring of the intensity of the pathologic process and to control efficiency of treatment measures according to fluctuation of its level. According to its serum values it can reflect a place of inflammation, e.g. in upper or lower airways, urinary tract etc. It helps to distinguish between bacterial and viral inflammations and to identify size of vascular lesions such as acute myocardial infarction, cerebral infarction, decompensation of atherosclerosis. Because of its easy detection and quick elevation CRP has not only a diagnostic importance but also a prognostic one and is a predictor of a risk of atherosclerosis. Although long lasting renal insufficiency (LLRI), renal failure (RF) and regular dialysis treatment (RDT) are indicated to elevate CRP level, authors present proves that adequately treated patient compensated with an adequate dialysis treatment has normal CRP values for a long time in spite of long lasting comorbidities including atherosclerosis. There has been done a long term monitoring of 10 patients with LLRI and 22 patients with RDT. Their CRP was monitored via a turbidimetric method using sets K-Assay made by company Kamya Bio Comp. Elevated CRP in the samples reflects an acute insult such as infection, cardiovascular disease, diabetes decompensation and last but not least quality of a dialysis treatment.
