Thrombinogenesis in patients with aseptic instability of knee endoprosthesis and periprosthetic infection

Year: 2020, volume 16 Issue: №2 Pages: 478-484
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Girkalo M.V., Shakhmartova S.G., Shpinyak S.P., Mandrov A.V., Kozadaev M.N., Puchinyan D.M.
Organization: Saratov State Medical University
Summary:

Objective: To evaluate thrombinogenesis in patients with periprosthetic infection and aseptic loosening of endoprosthesis after primary knee arthroplasty. Material and Methods: 28 of 52 examined patients who suffered from the loosening of knee endoprosthesis components and 24 from periprosthetic infection; 18 healthy individuals were also engaged into the study. Thrombinogenesis was analyzed with thrombin generation assay in an automated Ceveron alpha coagulometer (Technoclone, Austria) using RB and RC-low activators containing 2 and 5 pmol/ml of tissue factor respectively. Each of the main groups of patients was divided into two subgroups: in patients of the 1st subgroups RC-low activator aggravate thrombinogenesis while in the 2nd subgroups it inhibited the process as compared to the effects of RB activator. Results: In the 1st subgroup of patients with aseptic loosening RC-low activator caused chronometric hyperthrombinogenesis, and in the 2nd — both chronometric and structural ones. In patients with periprosthetic infection the effects of RB and RC-low activators were comparable. Conclusion: In patients with aseptic loosening of the implant and stopped periprosthetic infection that developed after primary knee replacement, the thrombin generation test reveals normal, paradoxical and inert types of thrombinogenesis.

Pathogenic specifics of articular cartilage metabolism regulation at the initial stage of gonarthrosis

Year: 2019, volume 15 Issue: №4 Pages: 939-943
Heading: Рathophysiology Article type: Original article
Authors: Puchinyan D.M., Gladkova E.V., Karyakina E.M., Belova S.V., Romakina N.A.
Organization: Saratov State Medical University
Summary:

Objective: to clarify specifics of articular cartilage metabolism regulation in early stages of gonarthrosis. Material and Methods. 66 women aged 41 to 60 у. o. (median age 49 years; Q25%=44; Q75%=55) were examined. The control (n=30) and the main (n=36) groups were arranged depending on knee osteoarthritis clinical and instrumental presentations, or their absence. The levels of cartilage oligomeric matrix protein (COMP), acidic fibroblast growth factor (FGF-1), vascular endothelial growth factor (VEGF-A), interleukin-1 (3 (IL-1 (3) and superoxide dismutase-2 (SOD-2) in serum have been determined by solid-phase enzyme immunoassay. Results. There was a statistically significant increase in the level of COMP in blood serum as well as the increase in number and strengthening of negative correlation between cytokinesand SOD-2 in women of the main group. Conclusion. The increased content of COMP in blood serum and the rise in number of negative correlations between SOD-2 on the one hand, and COMP, IL-1 (3 and VEGF-A on the other may be early osteoarthritis presentations in the examined individuals.

Year: 2019, volume 15 Issue: №4 Pages: 934-939
Heading: Рathophysiology Article type: Original article
Authors: Ponamarev I.R., Puchinyan D.M., Shchanitsyn I.N.
Organization: Saratov State Medical University
Summary:

Objective: to analyze diagnostic significance of neopterin, VEGF, sICAM, sVCAM, IL-6, TNF-a and MMP-9 in determining the nature of tumor process in musculoskeletal neoplasms. Material and Methods. 64 patients with benign (44) and malignant (20) musculoskeletal tumors aged 18to65y. o. were examined. Neopterin, VEGF, sICAM, sVCAM, IL-6, TNF-a and MMP-9 in serum were studied by enzyme immunoassay (p=0.07). Results. A statistically significant increase in the expression of regulatory molecules, neopterin (p<0.001), VEGF (p=0.02), slCAM-1 (p<0.001), IL-6 (p<0.001), TNF-a (p=0.02) in particular has been discovered and a pronounced tendency for the increase of MMP-9 level has been in evidence. Using ROC analysis, threshold values for each parameter have been determined. The most informative cytokines (neopterin, sICAM and IL-6) have been identified with multivariable regression method. Conclusion. The levels of neopterin, slCAM-1, IL-6 in the serum of patients with malignant musculoskeletal neoplasms above the threshold values predict an unfavorable course of the disease.

Hemostasis test parameters in patients requiring revision knee arthroplasty

Year: 2018, volume 14 Issue: №2 Pages: 266-271

Authors: Girkalo M.V., Shakhmartova S.G., Shpinyak S.P., Mandrov A.V., Kozadaev M.N., Puchinyan D.M.
Organization:
Summary:

Objective: comparative analysis of the blood coagulation system in patients requiring revision arthroplasty of the knee joint in connection with the developed infectious and aseptic complications after total arthroplasty. Material and Methods. 37 patients with complications of total knee replacement were examined. Patients were divided into 2 groups: 1st — with signs of suppuration (n=19); 2nd — withsigns of aseptic instability of the endoprosthesis components (n=18). The control group consisted of 22 conditionally healthy people. Studied screening coagulation: activated partial thromboplastin time, prothrombin time, fbrinogen concentration, thrombin time, antithrombin III, protein C, the content of soluble fbrin-monomer complexes and D-dimers. Results. There was an increase in activated partial thromboplastin time in patients of group 2, prothrombin time — in patients of groups 1 and 2 compared with the data obtained in the control group (p<0.001). An increase in the content of soluble fbrin- monomer complexes and D-dimers was recorded in the blood plasma of patients of the 1st and 2nd groups compared to their level in the control group (p<0.001). Conclusion. The data of local coagulogram tests in patients requiring revision arthroplasty of the knee joint refect the signs of maladaptation in the hemostatic system at the preoperative stage of examination. It is worth noting the lack of information content of the screening coagulogram, as its basic tests do not refect changes in the whole system of homeostasis, the search for new informative research methods remains relevant today.

The capacity of the thrombin generation test in the diagnostics of hemostasis system disorders in patients with osteoarthritis

Year: 2018, volume 14 Issue: №3 Pages: 602-606
Heading: Traumatology and Orthopedics Article type: Original article
Authors: Shakhmartova S.G., Vorobyova I.S., Puchinyan D.M.
Organization:
Summary:

Aim: to determine the diagnostic significance of thrombin generation test parameters in the diagnostics of hemostatic disorders in patients with osteoarthritis of large joints in preoperative period. Material and Methods. 137 subjects have been investigated, among whom there were 115 hip and knee osteoarthritis patients, submitted for primary arthroplasty (68) and re-prosthetics (47); control group — 22 conventionally healthy blood donors. All subjects underwent plasma hemostasis study and thrombin generation test with two activators — RB (TF 2 pmol/ml) and RC-low (TF 5 pmol/ ml). Osteoarthritis patients were divided into two groups according to the results of thrombin generation test. The 1st group included patients with an adequate response to the stronger activator (t-lagR >t-lag ow, tt-peak^tt-peak^^), the 2nd —with an inversion response (t-lagRBlow). Results. In trie control group and group 1 patients, the thrombin formation process is more pronounced when using an activator with a high TF(RC-low) content than when using an activator with a lowTF (RB) content, which is regarded as an adequate reaction of thrombin formation to the action of a stronger agonist. Patients of the 2nd group inresponse to the action of the activator with a high content of TF was observed inhibition of the reaction of formation of thrombin, which was reflected in the slowdown in the speed of the generation of this enzyme and reduce its quantity. Conclusion. The use of two activators with different concentrations of tissue factor in the test of thrombin generation allows the nature of the response of the hemocoagulation system to initiate the process of thrombin formation to identify patients with adequate and inadequate response.
