Organization: Saratov State Medical University
Summary:

The aim is to develop methods for detection of hyaline cartilage metabolic imbalance in patients with initial degenerative dystrophic changes in the substantiated pathogenetically knee. Material and Methods. Subject of inquiry: 50 women aged from 35 up to 57 (49.1 ±2.4), among them 36 patients with an early stage of knee osteoarthrosis made up an experimental group, 14 women without any musculoskeletal disease clinical presentations made up a control group. We carried out a complex examination including physical assessment, study of orthopaedic status, interview with the use of KOOS (Knee Injury and Osteoarthritis Outcome Score) scale, roentgenography and MRI of the knee and also a number of laboratory tests: enzyme-linked immunosorbent assay determination of the content of cytokine profile indices (IL-1, TNF-a, IL-6), cartilage oligomeric matrix protein (COMP) and bone (SerumCrossLaps and bone isozyme of alkaline phosphatase (BAP)) tissue metabolism markers in blood serum in all the groups of patients. Results. In all the patients of the experimental group the roentgenologic stage of osteoarthrosis was defined as 0-1 according to J. Lawrence and J. Kellgren, but at the same time knee degenerative changes were objectivized on the series of MR images in the form of MR signal changes of the articular cartilage, erosions and cysts, degenerative meniscus. We observed increased serum cartilage oligomeric matrix protein (COMP) in the same group and that is characteristic of hyaline cartilage destruction activation. We also detect disorders in bone tissue remodeling in the form of bone resorption intensification (Serum CrossLaps), osteogenesis increase (BAP) and activation of proinflammatory cytokine system link (IL-1, TNF-a). Conclusion. The leading pathogenetic links of the early degenerative changes of the knee are hyperproduction of proinflammatory cytokines (IL-1, TNF-a), destruction of the hyaline cartilage and disorder in bone tissue remodeling. Assessment of biochemical predictors of cartilage and bone tissue degradation along with the instrumental methods of diagnosis is of great theoretical and practical importance in the system of early detection of incipient osteoarthrosis.

The cytokine status and the levels of thyroid hormones in children with acute respiratory viral infections

Year: 2018, volume 14 Issue: №1 Pages: 61-65
Heading: Infectious Diseases Article type: Original article
Authors: Malinina N.V., Malyugina T.N.
Organization: Saratov State Medical University
Summary:

The research goal is to study the performance of INF-а, INF-y and IL-1(3 in children with acute respiratory viral infection (ARVI) depending on etiology, the presence of mixed infection, disease severity, presence of complications, the concentration of thyroid hormones. Material and Methods. Examined 147 patients aged from 1 to 10 years at the outbreak of the ARVI and 15 healthy children. Patients in the midst of acute respiratory infections was conducted to determine levels of IL-1(3, INF-а, INF-y, triiodothyronine (T3) and free thyroxine free (T4) by ELISA using standard test kits JSC "Vector-best" (Koltsovo, Novosibirsk region). Results. It was showed elevated level of INF-y in patients with PC-infection in comparison with the same indicator in healthy children. Set the increased level of INF-а in severe ARVI and the level of INF-y at medium severe form. It was showed increased levels of INF-y in patients with mixed infection. In children with complications, the level of IL-1 (3 was lower almost in 2.4 times, than in children without complications. Among patients with complications, the highest numbers of INF-а were detected in children with pneumonia and INF-y increased in patients with bronchitis. When conducting correlation analysis, the highest rates of INF-а were observed in children with the syndrome of "low T3", and INF-y in children as low T3 and low T4. Conclusion. An increase in the level of INF-y in patients with RS infection was found. Revealed that in children in acute period of SARS levels IL-1 IS, INF-а do not depend on the etiological factor of SARS. These indicators are influenced by the severity of the disease, which in our study was due to the development of mixed infection, the presence and nature of complications. High rates of INF-а and INF-y have significant inverse correlation with the level of T3, which reflects the degree of intoxication in the acute period of infectious diseases.

Prediction of heart remodeling in patients with bronchial asthma

Year: 2018, volume 14 Issue: №1 Pages: 49-52
Heading: Internal Diseases Article type: Original article
Authors: Ryabova A.Yu., Shapovalova T.G., Shashina M.M., Lekareva L.I., Kudishina M.M.
Organization: Saratov State Medical University
Summary:

The aim of the study was to identify cardiac remodeling in bronchial asthma (BA), to construct a mathematical model for its prediction to optimize diagnosis. Material and Methods. Atotal of 283 patients with asthma who underwent a comprehensive examination including general clinical, immuno-enzymatic (determination of the N-terminal fraction of the brain natriuretic propeptide, activity of the angiotensin-converting enzyme) and instrumental methods: ECG, ECHO, daily Holter monitoring of ECG, FVD. Results. The analysis of the obtained results showed that in patients with asthma, structural, geometric changes of the myocardium of the right and left ventricles were noted, increasing as the disease became more severe. The activation of local neurohormonal systems, primarily myocardial is no less important. An analysis of the relationship between the concentration of natriuretic peptide and the end-diastolic size of the right ventricle in BA patients revealed a moderate correlation relationship. There was a weak correlation between the right ventricular end-diastolic size, the right ventricular frontal wall thickness and the ACE level. The analysis of the relationship between the above dimensions of the right ventricle and the index of the balance of the autonomic nervous system was reliable. Conclusion. Thus, the development of cardiac remodeling in AD patients occurs against the background of the hyperactivation of neurohumoral systems, including sympathoadrenal, renin-angiotensin-aldosterone and the system of natriuretic peptides.

Organization: Saratov State Medical University, Saratov state university, Skolkovo Institute of Science and Technology
Summary:

The aim is to assess skin microcirculation changes arising during subcutaneous implantation of polycaprolactone scaffolds mineralized by vaterite. Material and Methods. The experiment was carried out on 30 albino rats divided into two groups: a negative control group and an experimental one. We implanted polycaprolactone scaffold with exhausted foreign protein subcutaneously into rats of the negative control group. We implanted polycaprolactone matrix mineralized by vaterite subcutaneously into the animals of the experimental group. Research methods include laser Doppler flowmetry and morphological examination of the tissues of the matrix implantation area. Results. Changes of skin microcirculation over the matrix allocation area correspond to the morphological pattern of tissue reactions. Biocompat-ibility disorders take the form of inflammation in the scaffold implantation area that is accompanied by stable perfusion rise associated with local bloodstream modulation changes. We did not observe inflammation signs in the surrounding scaffold tissues during implantation of polycaprolactone matrices mineralized by vaterite. Besides local microcircula-tory reactions possess a transient character disappearing completely by the 21st day after the implantation. Conclusion. Complex of the given functional and morphological studies allow us to ascertain high-grade biocompatibility of polycaprolactone matrices mineralized by vaterite thus giving rise to prospect of their use for tissue regeneration stimulation.

Summary:

The aim: to study etiological role of opportunistic microflora in the pathogenesis of implant-associated inflammation in patients after primary knee joint replacement and antibiotic sensitivity of main agent groups. Material and Methods. The retrospective analysis of microbiological samples of 383 patients with implant-associated inflammation occurred after primary total knee replacement. Results. Gram-positive cocci (63.5%) are the leading agents of implant-associ- ated inflammation, and there is an increase in the etiological role of coagulase-positive Staphylococci. Main agents of Gram-negative group were Enterobacteraceae and non-enzyme bacteria. We revealed high resistance of Staphylo-coccus spp. to antibiotics of various groups. Oxazolidinones and glycylcyclines were the most active among all antibiotic groups. Gram-negative bacteria were highly resistant to cephalosporine and macrolides with carbapenems and fluoroquinolones being most active. Conclusion. Gram-negative Enterobacteraceae, non-enzyme bacteria and Gram-positive cocci are most significant etiological factors in the pathogenesis of implant-associated inflammation in patients after primary total knee replacement.
