Relevance.Currently, there is no universally recognized standard method for diagnosis of sepsis in patients with burn injury, which causes many variations when recording septic conditions and also high mortality of such patients. Traditionally, patients in intensive care units are assessed using the clinical scales SOFA, APACHE II-IV or SAPS II-III. However, most of the known clinical scales cannot always be used to assess the severity of burn injuries. Therefore, unrecognized sepsis can lead to the multiple organ dysfunction syndrome that is the main cause of death in burn patients. The definition, systematization and standardization of new criteria for sepsis and predictors of its development can significantly improve the medical care for patients in this category and reduce the level of mortality.Intention.To review the studies of burn sepsis biomarkers using publications from the National Center for Biotechnological Information and the Scientific Electronic Library (eLIBRARY) over 2003–2017.Methodology.This article provides an overview of the most promising clinical and laboratory markers of sepsis with high predictive and diagnostic value that can be used to predict and assess the severity of burn injuries.Results and their analysis.Over the past 15 years, many potential biomarkers of burn sepsis have been studied. The most promising of them are: tumor necrosis factor-alpha, interleukin-6, interleukin-8, interleukin-10, interleukin-27, presepsin, endotoxin of gram-positive bacteria, lipopolysaccharide-binding protein, soluble receptor of urokinase-type plasminogen activator, trigger receptor expressed on myeloid cells, and myeloperoxidase. The most topical current method for laboratory diagnostics of these biomarkers can be the enzyme-linked immunoassay in the biochip format.Сonclusion.Integrated and simultaneous measurements of the sepsis markers reviewed in this article within one study can be useful for diagnosing sepsis in severely burned patients in the future.

Patients who suffer from severe burns develop metabolic imbalances and systemic inflammatory response syndrome (SIRS) which can result in multiple organ failure and death. Research aimed at reducing the inflammatory process has yielded new insight into burn injury therapies. In this review, we discuss strategies used to curb inflammation in burn injuries and note that further studies with high quality evidence are necessary.

Objective: to conduct pharmacoepidemiological analysis and analysis of the costs of pharmacotherapy, taking into account the actual consumption of drugs in the real inpatient clinical practice at the federal center in Russia. Materials and methods. Data from the medical records of 14 patients with burn injury, who were hospitalized in 2018, was analyzed. Patients’ age was from 23 to 67 years (44,93 ± 14,66). Duration of hospitalization was from 17 to 62 days (35,93 ± 14,17). We calculated rate of prescription foe each drug and its share in general structure of all utilized drug courses (n = 460). We performed frequency analysis of prescription structure, DDD (defined daily doses) analysis, DU90% (Drug Utilization 90%) analysis, ABC-analysis and analysis of average cost of pharmacotherapy. Results. Most frequently used drugs, prescribed in 75-100% of all hospital cases, included 15 names, e.g. 2 antimicrobial drugs (vancomycin and amikacin), 19 were used commonly, including 4 antimicrobial drugs (co-trimoxazole, cefoperazone/sulbactam, tigecyclin and cefepime). Other drugs were used in less than 25% of cases. 33 drugs made 90% of all consumed NDDD, including 5 antimicrobial drugs (vancomycin, amikacin, co-trimoxazole, cefoperazone/sulbactam and tigecyclin). These drugs comprised 70,24% in the prescription structure. The cost of one DDD in DU90% segments (512,33 rubles) is 1,4 higher than in DU10% segment (649,34 rubles). Average cost of drugs included in DU90% group was 4735,89 rubles vs 4966,80 rubles for drugs from DU10% group. This finding shows positive tendency of burn injuries pharmacological treatment. Conclusion. We obtained the data, which can be used for comparison of real clinical practice costs with a current payment rates for medical care.

Physical exercise reduces the biochemical markers of obesity, but the effects of multicomponent interventions on these markers should be explored. The present study aimed to elucidate how overweight/obese adolescents respond to a multicomponent program approach on body composition, physical fitness, and inflammatory markers, using a quasi-experimental study with 33 overweight/obesity adolescents (control group (CG) = 16; intervention group (IG) = 17). The intervention consisted of 24 weeks with physical exercises and nutritional and psychological guidance. Both groups were evaluated at the pre/post-intervention moments on body mass index (BMI); body fat (%Fat); waist circumference (WC); waist/hip ratio (WHR); waist-to-height ratio (WHtR), cardiorespiratory fitness (CRF); abdominal strength, flexibility; leptin; interleukin 6; interleukin 10; and tumor necrosis factor-alpha. Mixed-analysis of variance and generalized estimation equations were used for statistical analysis. There was an interaction effect between groups and time on %Fat (p = 0.002), WC (p = 0.023), WHR (p < 0.001), WHtR (p = 0.035), CRF (p = 0.050), and leptin (p = 0.026). Adolescents were classified as 82.4% responders for %Fat, 70.6% for WC, 88.2% for WHR, and 70.6% for CRF. Further, there was an association between changes in %Fat (p = 0.033), WC (p = 0.032), and WHR (p = 0.033) between responders and non-responders with CRF in the IG. There was a positive effect on body composition, physical fitness, and leptin. In addition, reductions in body composition parameters were explained by CRF improvements.

ABSTRACT Clearing blood-stage malaria parasites without inducing major host pathology requires a finely tuned balance between pro- and anti-inflammatory responses. The interplay between regulatory T (Treg) cells and dendritic cells (DCs) is one of the key determinants of this balance. Although experimental models have revealed various patterns of Treg cell expansion, DC maturation, and cytokine production according to the infecting malaria parasite species, no studies have compared all of these parameters in human infections with Plasmodium falciparum and P. vivax in the same setting of endemicity. Here we show that during uncomplicated acute malaria, both species induced a significant expansion of CD4+ CD25+ Foxp3+ Treg cells expressing the key immunomodulatory molecule CTLA-4 and a significant increase in the proportion of DCs that were plasmacytoid (CD123+), with a decrease in the myeloid/plasmacytoid DC ratio. These changes were proportional to parasite loads but correlated neither with the intensity of clinical symptoms nor with circulating cytokine levels. One-third of P. vivax-infected patients, but no P. falciparum-infected subjects, showed impaired maturation of circulating DCs, with low surface expression of CD86. Although vivax malaria patients overall had a less inflammatory cytokine response, with a higher interleukin-10 (IL-10)/tumor necrosis factor alpha (TNF-α) ratio, this finding did not translate to milder clinical manifestations than those of falciparum malaria patients. We discuss the potential implications of these findings for species-specific pathogenesis and long-lasting protective immunity to malaria.

Human CD4+ T cells, activated by allogeneic monocytes in a primary mixed lymphocyte reaction in the presence of exogenous interleukin (IL) 10, specifically failed to proliferate after restimulation with the same alloantigens. A comparable state of T cell unresponsiveness could be induced by activation of CD4+ T cells by cross-linked anti-CD3 monoclonal antibodies (mAbs) in the presence of exogenous IL-10. The anergic T cells failed to produce IL-2, IL-5, IL-10, interferon gamma, tumor necrosis factor alpha, and granulocyte/macrophage colony-stimulating factor. The IL-10-induced anergic state was long-lasting. T cell anergy could not be reversed after restimulation of the cells with anti-CD3 and anti-CD28 mAbs, although CD3 and CD28 expression was normal. In addition, restimulation of anergized T cells with anti-CD3 mAbs induced normal Ca2+ fluxes and resulted in increased CD3, CD28, and class II major histocompatibility complex expression, indicating that calcineurin-mediated signaling occurs in these anergic cells. However, the expression of the IL-2 receptor alpha chain was not upregulated, which may account for the failure of exogenous IL-2 to reverse the anergic state. Interestingly, anergic T cells and their nonanergic counterparts showed comparable levels of proliferation and cytokine production after activation with phorbol myristate acetate and Ca2+ ionophore, indicating that a direct activation of a protein kinase C-dependent pathway can overcome the tolerizing effect of IL-10. Taken together, these data demonstrate that IL-10 induces T cell anergy and therefore may play an important role in the induction and maintenance of antigen-specific T cell tolerance.

Core Set

Burn injuries cause disability and functional limitations in daily living. In a 2015 fire explosion in Taiwan, 499 young people sustained burn injuries. The construction of an effective and comprehensive rehabilitation program that enables patients to regain their previous function is imperative. The International Classification of Functioning, Disability, and Health (ICF) includes multiple dimensions that can contribute to meeting this goal. An ICF core set was developed in this study for Taiwanese patients with burns. A consensus process using three rounds of the Delphi technique was employed. A multidisciplinary team of 30 experts from various institutions was formed. The questionnaire used in this study comprised 162 ICF second-level categories relevant to burn injuries. A 5-point Likert scale was used, and participants assigned a weight to the effect of each category on daily activities after burns. The consensus among ratings was assessed using Spearman’s ρ and semi-interquartile range indices. The core set for post-acute SCI was developed from categories that attained a mean score of ≥4.0 in the third round of the Delphi exercise. The core ICF set contained 68 categories. Of these, 19 comprised the component of body functions, 5 comprised body structures, 37 comprised activities and participation, and 7 comprised environmental factors. This preliminary core set offers a comprehensive system for disability assessment and verification following burn injury. The core set provides information for effective rehabilitation strategy setting for patients with burns. Further feasibility and validation studies are required in the future.

Severe Burn Injuries

Abstract This work is dedicated to the detection of imbalance between the pro- and anti-coagulant branches of hemostasis at severe burn injuries by evaluating the content or activity of individual clotting factors. To select the targets for accurate diagnostics we measured the concentrations of soluble fibrin monomeric complexes and fibrinogen, levels of total prothrombin, factor X, protein C and antithrombin III, and recorded the time of clotting in activated partial thromboplastin time and prothrombin time tests. Factor X level was increased in 26 % of patients on the first day after the burn and it rose further in 62 % patients on the 14 th day of recovery. Increasing factor X level is assumed to be a risk factor of thrombotic complications. We propose to use it as a marker of predisposition to thrombosis at severe burn injury.

Abstract The study was designed on whether YouTube videos are useful as an information resource in the field of burn injury prevention and management. Current literature on the educational content and quality of burn-related first aid videos on YouTube was reported as inadequate and inaccurate. However, the quality of YouTube videos on various medical and clinical topics has been the subject of many previous studies, and there has been increasing evidence that the content ratio of usefulness was higher than that of non-useful. While hours and even minutes in burn injuries are as precious as gold in terms of outcomes, it would be a significant loss not to use the most popular and easily accessible free social media platform of our time as a tool that can contribute to the prevention of burns and raise awareness. Analysis was conducted with the remaining 96 videos from 240 videos obtained from YouTube, according to possible search terms and exclusion of videos according to predetermined criteria. The Global Quality Score (GQS) and modified DISCERN (m.DISCERN) tools were used to assess the quality and reliability of the videos. Viewer engagement metrics and video properties were also investigated according to the usefulness criteria (e.g., video length, duration on YouTube, topic contents, source uploads, reliability, and quality). Finally, it was revealed that nearly 80 percent of the YouTube videos contained information in the field of the prevention and management of burn injuries deemed useful in this study, comparable to the other medical disciplines' reports in the literature.

Abstract Neurodevelopmental symptoms (NS) including attention and behavioral problems, developmental delays, intellectual disabilities and learning problems are prevalent in children with burn injuries. The presence of NS may predispose children to poorer burn injury recovery outcomes compared to children without these symptoms (non-NS). The Multi-Center Benchmarking Study (MCBS) monitored recovery outcomes in children with burn injuries in real time utilizing the Burn Outcomes Questionnaire (BOQ). The objective of this study was to retrospectively assess the long term burn recovery outcomes in NS patients versus non-NS patients from the MCBS population. This study assessed parent-reported BOQ outcomes in a sample of 563 patients aged 5 to 18 years who were admitted for burn injuries to a pediatric burn center. A subsample of patients had reported NS (n=181). Analyses compared BOQ outcomes within the NS subsample and the non-NS subsample (n=382) across three longitudinal points post-discharge. The prevalence rate of NS was 32.1% in the full sample. Findings revealed statistically significant improvement in the recovery curves in all five BOQ subscales for the non-NS group and all subscales except for Compliance for the NS group across all longitudinal points. When compared to non-NS patients, NS patients had significantly poorer burn recovery outcomes on the Satisfaction and Compliance subscales. Although it is important to educate all clinicians, parents, and children on burn prevention efforts, targeted education is necessary for children with NS since they may be at greater risk for burn injury as well as worse recovery outcomes.
