Organization: Scientific Research Institute of Traumatology Orthopedics and Neurosurgery of Saratov State Medical University n.a. V.I. Razumovsky
Summary:

Aim: to determine the concentration of MMP-9, TNF-a and IL-6 in blood serum of patients with benign and malignant bone tumors and feasibility of cytokine data use for differential diagnostics of the neoplastic process nature. Material and Methods. Levels of matrix metalloproteinase-9 (MMP-9), tumor necrosis factor-a (TNF-a) and interleukin-6 (IL-6) in blood serum were determined by the immunoenzyme method in 64 patients with bone tissue neoplasms (fibrous dysplasia, osteocystoma, giant-cell tumor, osteosarcoma, chondrosarcoma, bone metastases, multiple myeloma). Re-sults. MMP-9 level was heightened in patients suffered from chondrosarcoma and multiple myeloma. TNF-a and IL-6 expression was increased in cases with bone metastases. MMP-9, TNF-a and IL-6 levels were higher in cases with malignant bone neoplasms than in cases with benign bone tumors. Conclusion. MMP-9, TNF-a and IL-6 participate in the neoplastic process pathogenesis directly. Nevertheless it is too early to speak about the diagnostic value of the cytokines in cases with tumorous bone affection.

Biomarkers content in blood serum of patients with osseous neoformations

Year: 2016, volume 12 Issue: №3 Pages: 358-361
Heading: Clinical Laboratory Diagnostics Article type: Original article
Authors: Korshunov G.V., Pavlenko А.А., Puchinyan D.M., Shakhmartova S.G.
Organization:
Summary:

The aim of the study was the estimation of several biomarkers in differentiation diagnostics of tumour diseases in osseous system. Material and methods. 160 patients with benign (115) and malignant (45) osseous neoformations were investigated. Neopterine, tumour necrosis factor (TNF-а), interleukin-6, adhesion molecules of vessel endothe-lium (sVCAM-1) and vascular endothelial growth factor (VEGF) levels were identified by ELISA solid-phase test and compared with the levels of 20 apparently healthy individuals. Tumor verification was fulfilled by X-ray, CT, MRI and histomorphological essay. Results. Both benign and malignant osseous tumour patients showed increased levels of neopterine, TNF-а and interleukin-6 being more significant with malignant processes. The level of sVCAM was decreased in patients of both groups and VEGF level corresponded to the control, these indexes did not show any differences between the groups. The assessment of diagnostic value of these cytokines indicates that positive results for TNF and neopterine give the ground for the final diagnostic decision while the same results for interleukin-6 give moderate basement for diagnostic decision. Conclusion. Increased TNF-а and neopterine levels allow substantiating the difference between benign and malignant osseous tumours and improving diagnostic quality.

Summary:

Objective: to detect markers of the systemic inflammatory response syndrome in patients with coxarthrosis by means of assessment of the status of the hemostasis system, endothelium function and inflammation intensity. Material and Methods. The indices of the plasmatic hemostasis, levels of VCAM-1, ICAM-1, ELAM-1, VEGF-A, neop-terin were analyzed. Results. It has been found that among the patients with hip coxarthrosis a group of patients (47%) with endothelium dysfunction, cellular immunity activation, a high content of Soluble Fibrin Monomer Complex and D-dimers and a group of patients (53%) without any abnormalities in these parameters should be differentiated. Conclusion. Among the patients with hip coxarthrosis a group with signs of a systemic inflammatory response syndrome (occurrence of endothelium dysfunction, cellular immunity activation, a high content of Soluble Fibrin Monomer Complex and D-dimers) and a group of patients with reference values of these parameters can be determined. The markers of the systemic inflammatory response syndrome in cases with hip osteoarthrosis are Soluble Fibrin Monomer Complex and D-dimers, high levels of intercellular adhesion molecule-1 (slCAM-1), vascular cell adhesion molecule-2 (sVCAM-1), cell adhesion E-selectin-1 (ELAM-1) and Neopterin (Np).

Organization: Saratov State Medical University, Saratov Scientific Research Institute of Traumatology and Orthopedics
Summary:

Research objective is to study antibacterial action of nanoparticles of iron and copper on polyantibiotically resistant clinical Staphylococcus aureus strains.
Materials and methods include antibacterial action of nanoparticles of copper and iron on 10 Staphylococcus au¬reus strains, isolated from patients with purulent complications stayed in the in-patient department of traumatology and orthopedics. Solutions of powders of iron and copper have been prepared directly before the experiment in concentra¬tion from 0,001 to 1 mg/ml.
it has been revealed that the influence of nanoparticles on growth of clinical strains and the intensity of antibacterial effect depends on the form of nanoparticles, their concentration and action time. concentration of 0,1 mg/ml and 1 mg/ ml of iron nanoparticles has provoked the decrease in quantity of microbe cells from 3 to 34 % (p <0,01). in smaller concentrations the reliable antibacterial effect has not been observed. Antibacterial activity of copper nanoparticles has been expressed in a wide range of concentrations from 0,001 mg/ml to 1 mg/ml, even during short-term action (30 minutes) it has provoked reduction of quantity of the microbe cells grown on the firm nutrient medium, 97-100 % in comparison with the control (p <0,001).
in conclusion it is to point out that copper nanoparticles have more expressed inhibitory effect on growth of clini¬cal strains of golden staphylococcus than iron nanoparticle suspension. inhibition degree depends on superdispersed powder dosage and incubation period

Immunological Indices At Gerontological Patients With Ischemic Heart Disease, Metabolic Disturbances And Osteoporosis

Summary:

Gerontological patients with ischemic heart disease which is not accompanied by such pathology as diabetes (SD) and osteoporosis (OP) with normal or increased body weight (females) generally have got «the highest potential of health». It has been proved by phase portraits and autoantibodies (AAb) and cytokines indices. Adaptative disturbances in these groups have been revealed at the age of 95 and 89 accordingly. The presence of such accompanying pathology as SD and OP causes dysadaptation. It is evident by means of autoantibodies (AAb) and cytokines indices and phase portraits of «temporary dependence of general cholesterol levels - its first derivative»

IMMUNOLOGIC INDICES IN GERONTOLOGICAL PATIENTS WITH ISCHEMIC HEART DESEASE AND URINARY SYSTEM PATHOLOGY

Summary:

Patients of middle and old age with ischemic heart desease and diseases of urinary system (DUS) have been examined. Leukocytic index of intoxication (Lll), hematologic parameter of intoxication (HPI), parameter of immunity intensity (Pll) have been significantly increased in groups of patients with benign prostatic hyperplasia, diabetes and DUS. These indices have been directly correlated with content of IL6 and TNFa, and examined autoantibodies (AAb), especially with contents of antibodies to DNA, to collagen, to fiber-regulator of differentiation and migration immature neuroblast S100. Indices of Lll, HPI and Pll have been decreased in group of patients with normal body weight and urolithiasis. In this group the increase of allergization index (Al) and content of IL6, TNFa has been noticed. Indices of AAb pointed to metabolic disorders. The increase of cytokines in patients with pyelonephritis has been revealed. Content of AAb has been slightly increased in comparison with normal indices
