Abstract

Introduction.  Nosocomial infections are a common complication in patients treated in the intensive care unit (ICU). Microorganisms with multidrug resistance are one of the significant risk factors for death in this category of patients. Aim. To study structure of infectious agents in ICU patients and parameters of their antibiotic resistance.  Materials and methods. Retrospective pharmacoepidemiological study of medical records of adult patients with infections diagnosed in ICU who were treated in City Clinical Hospital No. 24 of the Department of Health (Moscow, Russian Federation) in the period 08/20/2022 — 07/31/2023 (n=199). The analysis (gender, age of patients, localization of the infectious process, data on the structure of pathogens and sensitivity to antibacterial drugs) included records with data on bacterial culture ( n=141). Results. In the structure of pathogens detected in ICU patients, gram-negative microflora predominated (54 %). Among the pathogens with a clinically significant growth, leaders were  K. pneumoniae (22 %), Candida spp. (20 %) and  Staphylococcus  spp. (19 %). K. pneumoniae was characterized by resistance to beta-lactams, aminoglycosides, and levofloxacin, the highest susceptibility was reported to colistin, 88.9 %.  Candida  spp. was overwhelmingly susceptible to all drugs used. Among Staphylococ caceae, S. aureus  was the most common (70 % resistance to ampicillin and cefoxitin).  Conclusion.  In the structure of infectious agents detected in ICU patients, a predominance of ESKAPE pathogens (the most prognostically important microorganisms: Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, Enterobacter spp.) was observed, including K. pneumoniae, S. aureus, A. baumannii, P. aeruginosa.  For all these microorganisms, except for Staphylococcaceae, a high level of antibiotic resistance was demonstrated.

Abstract

Purpose of the study. Conducting an assessment of the economic consequences (clinical and economic analysis) when conducting cytogenetic studies before prescribing various first-line treatment regimens for multiple myeloma (MM). Materialsand methods. The pharmacoeconomic study was carried out using the method of cost analysis, “cost-effectiveness” within the framework of the State Guarantee Program (SGP). Results. A review of the literature demonstrated that a limited number of data are currently available on the clinical effectiveness of the analyzed regimens in the first line, both in patients with normal and high cytogenetic risk. The cost-effectiveness analysis showed that among the three studied 1st-line treatment regimens (VMP, Rd, VRd), in terms of PFS (progression-free survival), the coefficient was minimal for the VMP regimen in patients with high cytogenetic risk. Conclusion. The study showed that the choice and prescription of first-line therapy, depending on the results of a cytogenetic study, is a clinically effective and cost-effective approach to organizing medical care for adult patients with multiple myeloma in the Russian Federation. This could be used in the future to formulate.

Abstract

Actuality. The search for parameters of clinical trials (CT) associated with the recruitment of patients is primarily associated with the search for parameters that can predict the recruitment — predictors of patient recruitment, since patient recruitment is an important and one of the most complex processes in clinical trials, the success of which depends on the entire study. The authors propose to use the parameters of the recruitment of patients assumed by the center, the number of exclusion criteria according to the protocol, and other simple methods that allow predicting the upcoming recruitment; however, the proposed approaches are unclaimed. The parameter of success in enrolling patients in the previous 10 or more studies proposed by the authors obviously has its drawbacks because clinical centers that did not participate in 10 successful studies are automatically excluded. However, the search for a simple parameter to predict upcoming recruitment continues; for example, the time of the first screening has its own predictor potential. We investigated changes in this parameter and its derivatives during the recruitment of patients to selected international multicenter clinical trials (IMCTs). Materials and methods. A retrospective analysis of 4 IMCTs of II–III phases was performed on the recruitment of patients and changes in the time parameters of the first screening and its derivatives. Aim. Consider changes in the time parameter of the first screening and its derivatives during patient recruitment. Statistical analysis. Descriptive statistics with typing. Results. The change in the time parameter of the first screening during the recruitment of patients for CT was considered. The time of the first screening varies depending on the type of clinical center and the experience of the principal investigator. Discussion. According to the literature, a change in the time parameter of the first screening may indicate the success of the recruitment of patients in the center. Conclusion. The changes in the time of the screening set studied by us will allow us to apply the obtained values in clinical trials.

QUALITY OF LIFE

Abstract

It is important for public health to monitor and improve the health indicators of the population using the system of patient's quality of life (HRQoL) assessment regardless of the nosology of the disease. The use of HRQoL assessment provides health authorities with a tool for additional analysis of the performance of health services and for making decisions about funding priorities. The definition of HRQoL is one of the decisive factors in the calculation of QALYs because it measures the effectiveness of medical treatment in terms of how much it prolongs and/or improves patients' lives. The aim of the study is to determine the QALYs of hemophilia patients in Nizhny Novgorod region by means of electronic questionnaire using the SF-36 questionnaire. Methods. A validated SF-36 short form questionnaire was used in the study, which was distributed to adult patients with hemophilia A, B and Willebrand's disease of Nizhny Novgorod region together with a short form of informed voluntary consent. Twenty-eight people participated in the questionnaire. Calculation of general and final indicators of the HRQoL was carried out according to the instructions for processing data obtained with the SF-36 questionnaire. Results. The lowest score among all respondents was for GH "General Health Status" with a mean value of 61.00, and the highest score was for PF "Physical Functioning" with a mean value of 81.43. The study revealed that the majority of the surveyed patients were receiving Emicizumab (42.86 %). After comparing the ranges of values of the final indicators of physical (PH) and mental (MN') health in patients with different forms of hemophilia, the highest values of HRQoL indicators are observed in patients with hemophilia B, and the highest range of extreme values — in patients with hemophilia A. Conclusion. Patients with different forms of hemophilia are determined to have satisfactory values of HRQoL indicators, as all the results obtained in the course of the questionnaire are above the average value of the indicators. Mean HRQoL scores in patients receiving emicizumab are at a similar level compared to patients receiving other LPs, and fluctuations in HRQoL scores in these patients are less marked than in the other patients with hemophilia A.

LITERATURE REVIEW

Abstract

Chronic kidney disease (CKD) and cardiovascular diseases are widespread throughout the world and are closely related to each other. Sympathetic hyperactivity, characteristic of CKD, increases cardiovascular risk and accelerates the progression of kidney disease by activating beta-adrenergic receptors. Beta-blockers play an important role in preventing the negative effects of in creased activity of the sympathetic nervous system on the cardiovascular system and kidneys, can slow the progression of renal disease, and have proven effective in reducing overall and cardiovascular mortality and treatment of coronary heart disease, heart failure, arterial hypertension, and arrhythmias in patients with CKD. Despite this, beta-blockers are still underused in patients with CKD, especially in its later stages, including ESRD. Although there are currently no clear recommendations for the choice of any specific beta blocker in CKD, factors such as the CKD stage, presence of diabetes mellitus or reduced insulin sensitivity, and pharmacodynamics (cardioselectivity, α1-blocking- and vasodilating properties) and pharmacokinetic properties (metabolism, routes of elimination from the body, degree of binding to plasma proteins and dualizability) should be considered. At present, along with ACE inhibitors, AT1-receptor antagonists, and SGLT2 inhibitors, beta-blockers remain indispensable drugs for treating cardiovascular diseases with proven positive effects on the progression of kidney failure in patients with CKD. Their broader use in this population is expected to further reduce cardiovascular mortality and delay the initiation of renal replacement therapy.

Abstract

Relevance. During and after the COVID-19 pandemic, viruses have become a more common cause of pulmonary infections in adults; therefore, the distinction between viral lung injury and community-acquired bacterial pneumonia is of increasing importance. Aim. Development of a model for differentiating community-acquired bacterial pneumonia and viral lung injury, including COVID-19. Materials and methods. This retrospective case–control study included 300 adult patients with viral lung injury and 100 adult patients with community-acquired bacterial pneumonia. Clinical, laboratory, and instrumental data were analyzed, significant factors were selected by which the samples differed, and a model was developed using logistic regression to distinguish between community-acquired bacterial pneumonia and viral lung damage, including COVID-19. Results. The developed model included the following parameters: total protein level, neutrophil/lymphocyte index, heart rate, unilateral infiltration on CT or chest x-ray, vasopressor prescription in the first 24 h of hospitalization, altered level of consciousness, chills, and fatigue. The model had the following characteristics: AUC = 0.94 (0.92–0.96), AUC_PR = 0.84 (0.76 to 0.92), prediction accuracy — 90%, sensitivity — 76%, specificity — 95%, positive predictive value — 83 %. Conclusion. The use of this model can facilitate the differential diagnosis of community-acquired bacterial pneumonia and viral lung injury, including COVID-19, in adults in general wards and intensive care units.

Abstract

Relevance. Monitoring of antibiotic resistance and the frequency of isolation of microorganisms at the regional level in each medical organization is of paramount importance for the implementation of epidemiological safety. Objective.  To identify the main microbiological trends based on the analysis of the microflora of patients in a single — profile hospital in order to implement weaknesses in strategic planning activities.  Materials and methods. A comprehensive analysis of the pharmacoepidemiological results of the consumption of antimicrobial drugs with calculated drug resistance indices and microbiological monitoring data demonstrated the presence of weaknesses and strengths for the strategic development of a multidisciplinary hospital at the regional level in terms of epidemiological safety.  Results . Statistically significant differences in the microbiological structure of pathogens are predetermined by the profile of medical care. The main trends in the change in the microflora of a multidisciplinary hospital as a whole are the prevalence of fungal and gram-negative pathogens over gram-positive ones. The presence of a relatively high index of consumpion of cephalosporins of 3–4 generations, fluoroquinolones, carbapenems, protected penicillins determines the high drug resistance index of Klebsiella pneumoniae (0.86) and characterizes the main microbiological trends of a multidisciplinary clinic.  Conclusion. Risk stratification by the level of multidrug-resistant pathogens, the use of deterrent strategies for prescribing antimicrobials, the implementation of educational modules, the evaluation of the effectiveness and monitoring of the risk stratification program with in the framework of antimicrobial technologies, the analysis of microbial landscape data using decision support programs are the main tasks of the functioning of a multidisciplinary team of specialists in a multidisciplinary clinic to control antibiotic resistance.

SYSTEMATIC REVIEW AND META-ANALYSIS

Abstract

Aim.  To assess the efficacy profiles of different dosing regimens of tofacitinib, baricitinib, and upadacitinib — novel selective oral Janus activated kinase inhibitors, in rheumatoid arthritis (RA). Materials and methods.  Randomized controlled trials of tofacitinib, baricitinib and upadacitinib in RA were identified from MEDLINE, and Cochrane databases. Random- effects models were used to estimate pooled mean differences (MD) and relative risks (RRs). American College of Rheumatology 20 % (ACR20), Health Assessment Questionnaire–Disability Index (HAQ-DI) were calculated.  Results. Twenty trials with an overall low risk of bias were identified. Tofacitinib, baricitinib, and upadacitinib improved RA control as deter -mined by ACR20 (RR, 2.03; 95 % CI, 1.87 to 2.20) and HAQ-DI (MD, −0.31; 95% CI, −0.34 to −0.28) compared with placebo.  Conclusion.  Tofacitinib, baricitinib, and upadacitinib significantly improve RA control. To make further decisions, comparative clinical trials of the Janus kinase inhibitors in the real-world clinical practice are necessary.

PROVISION OF DRUGS

Abstract

The federal program of preferential drug provision in cardiology shows its effectiveness. However, hypercholesterolemia (HCH) remains a significant problem in patients in whom high-dose statin therapy does not provide the target level of low-density lipoprotein cholesterol (LDL cholesterol). The solution to the problem lies in the plane of prescribing lipid-lowering drugs of a different mechanism of action, for example, inhibitors of the PCSK9 enzyme. To recommend the inclusion of such kind drugs in the program, it is necessary not only to have evidence of their life-saving effect, but also the economic feasibility of their use. Aim: to evaluate the economic efficacy of alirocumab (INN) including in the federal program for patients who have suffered an acute coronary event, are receiving statins and have an LDL CH level of 5.0 mmol/l and higher.

Materials and methods. Modeling was applied in a target group of 3029 patients of working age who had undergone ACS during the previous 12 months with severe, including familial, HCH, with LDL cholesterol 5.0 mmol/l and higher, receiving statins taking into account previously determined outcomes when using alirocumab + statins for 5 years. Direct medical and non-medical costs, as well as indirect costs, are identified. The cost-effectiveness analysis was applied from the point of view of the effectiveness of treatment (effects on mortality, temporary disability, disability) and direct health care costs (additional drug provision and outpatient follow-up, specialized, including high-tech, medical care in a 24‑hour hospital). Two healthcare technologies were compared: statin therapy and use of alirocumab + statins. The calculations used according to domestic methods used the cost of medical treatment, temporary disability, hospitalizations, loss of GDP and other parameters.

Results. Modeling has shown a decrease in mortality, morbidity and disability when using alirocumab in even the first year of use. The economic effect of alirocumab from a decrease in temporary disability in the 1st year is 304.5 mln rub., in the 2nd — 301.5 mln rub., in the 3rd — 321.1 mln rub., in the 4th — 333.1 mln rub. The estimated amount of prevented GDP losses from mortality in the target group for 4 years in the case of alirocumab use amounted to 1,260.2 mln rub. The annual amount of avoidable GDP losses from mortality in the target group in the case of alirocumab is 27–30 %. The annual average savings per patient in the case of alirocumab use are from 7 to 17 %. The greatest impact on reducing losses from disability and mortality of the target group is noted in the group of people aged 40–59 years. Only for this group, if alirocumab is used, it is possible to reduce losses from disability and mortality by 159.2 million rubles per year (83 % of the total economic effect). Starting from the 4th year of alirocumab use, it is possible to obtain a positive economic effect in terms of hospitalization costs.

Conclusion. When alirocumab is included in the program of additional drug provision in cardiology, the share of costs for the purchase of alirocumab for the target group may be only 0.01 %. At the same time, the economic effect of inclusion in the first year alone will amount to at least 393.4 million rubles of budget funds. The total amount of avoidable losses due to the alirocumab usage may amount to 1,638 million rubles over 4 years.
