Despite the informative value of ultrasound examination of atherosclerotic vascular lesions, predicting­ the plaque vulnerabili­ty remains difficult. Circulating blood biomarkers could provide additional criteria that would allow better determination of the risk of recurrent stroke. The aim of our study was to estimate the level of C-reactive protein (CRP), low-density lipoproteins (LDL) and lipoprotein-associated phospholipase A2 (Lp-PLA2) in the blood of patients in the early recovery period of atherothrombotic stroke depending on the density of atherosclerotic plaque according to duplex scanning of cerebral vessels. Clinical and laboratory analysis of 69 men and 61 women aged (60.42 ± 7.40) years in the early recovery period of atherothrombotic stroke was conducted. Depending on the structure of the atherosclerotic plaque the examinees were divided into two groups with stable (n = 80) and unstable (n = 50) atherosclerotic layers. The blood lipid spectrum was examined on a biochemical analyzer Screen master, the level of CRP was determined with a diagnostic kit and that of Lp-PLA2 by ELISA. Significantly higher levels of LDL, CRP and Lp-PLA2 were observed in patients with unstable atherosclerotic plaque compared to patients with stable atherosclerotic plaque in the early recovery period of atherothrombotic stroke. The increased level of LDL, CRP, and Lp-PLA2 in patients with cerebral atherosclerosis can be considered as an indicator of the vulnerability of atherosclerotic plaques, prone to rupture, and as a prognostic marker of repeated acute ischemic events.

Prostate cancer (PCa) is the major cause of the death of men population globally. Multiple factors are involved in the initiation and progression of PCa. This study aimed to evaluate different metabolic parameters in the serum of PCa patients. Males of 50 years and above age with the recent diagnosis of PCa (digital rectal examination, and elevated serum prostate-specific antigen (PSA) level) were included in the study. Glucose and serum electrolytes level, lactate dehydrogenase activity, parameters of lipid metabolism and liver and kidney functioning were measured on a fully automated analyzer using standard reagent kits. Oxidative stress was evaluated by measuring MDA, CAT, GSH, and SOD in serum. Detection of C-reactive protein (CRP), insulin-like growth factor (IGF-1) and vascular endothelial growth factor (VEGF) was performed by immunoassay. It was shown that serum glucose and HDL levels were lower while total cholesterol, LDL and triglyceride levels were significantly higher in PCa group than in the control group. PCa patients had an elevated level of liver and kidney functional markers. Comparison of the oxidative stress markers in patient and control groups showed significant difference. It was detected that serum levels of CRP, IGF-1 and VEGF were significantly higher in PCa group, compared the control to group (P < 0.05). Low level of glucose and dyslipidemia indices in prostate cancer patients indicated metabolic changes and demonstrated the importance of multiple parameters analysis (free PSA, dyslipidemia, VEGF, IGF-1, CRP, and oxidative stress markers) for early PCa diagnostics.

The associative links between base concentration of C-reactive protein (hsCRP), levels of serum antiendotoxin antibodies of different classes and endotoxin-binding capacity of monocytes and granulocytes of healthy volunteers were investigated­ by cluster analysis. In the group of healthy volunteers with increased base concentration of hsCRP in blood the levels of serum antiendotoxin antibodies of different  classes and endotoxin-binding capacity of monocytes and granulocytes were reduced. Thus, the disbalance of detoxification and clearance of  endotoxin by humoral and cellular mechanisms can be one of the possible causes of development of low intensity inflammation and increase of hsCRP concentration in blood.

We examined patients with type 1 (DM 1) and type 2 (DM 2) diabetes mellitus. The concentration of C-reactive protein (CRP) in the blood and levels of serum antibodies to different classes of enterobacterial lipopolysaccharides (LPS) were determined by ELISA. Using cluster analysis it was shown that in 40.8% DM-1 patients the increased concentration of CRP is associated with a decrease in the levels of serum anti-LPS-IgA, anti-LPS-IgM and anti-LPS-IgG. In 56.7% of DM-2 patients with increased concentration of CRP levels of serum anti-LPS-IgA and anti-LPS-IgM were not significantly different from the normal values, but the levels of serum anti-LPS-IgG were significantly increased. Activation of inflammation and increase of concentration of the CRP in the blood of DM-2 patients is accompanied by a significant increase in the levels of serum anti-LPS-A and anti-LPS-G, as well as the tendency to reduce the levels of anti-LPS-IgM. The results of this study suggest an association between low intensity inflammation and immune response to enterobacterial LPS  in type 1 and 2 diabetes mellitus.
