Objective. To review the basic principles and functionality of the AMRmap online resource. Materials and Methods. The AMRmap platform was developed using the R programming language and various downloadable modules – packages. The current annually updated version of EUCAST clinical breakpoints was applied for determination of categories of susceptibility to antimicrobial agents. Descriptive analysis includes calculation of absolute and relative frequencies, median values, and confidence intervals using the Wilson method. Categorical variables are compared using Fisher’s exact test and Holm correction method for multiple comparisons. The algorithms are used to visualize multiple comparisons, kernel regression for trend analysis, and algorithms for finding associative rules. Results. The developed surveillance system includes modules for filtering, analyzing and visualizing antibiotic resistance data. The filters allow creating a sample of data with a specific list of parameters. A tab-based separation of analysis and visualization options ensure efficient stepwise evaluation of results. Data saving and sharing functions are also provided. Conclusions. This web-based informatics system provides a convenient way to AMR data from prospective microbiological surveillance studies in Russia. AMRmap can be accessed at https://amrmap.ru.

Objective. To assess rates of antimicrobial resistance and production of the clinically important acquired resistance mechanisms (extended spectrum beta-lactamases [ESBL] and carbapenemases) in nosocomial strains of Enterobacterales, and to determine genotypes and prevalence of “international high-risk clones” among carbapenemase-producing Klebsiella pneumoniae isolated in various Russian regions within the “MARATHON 2015–2016“ study. Materials and Methods. A total of 2786 non-duplicate nosocomial isolates of Enterobacterales, including 1316 isolates of K. pneumoniae and 837 isolates of Escherichia coli isolated in 49 hospitals from 25 cities in Russia in 2015–2016 were studied.

Aim: bring to the attention of practitioners indications for anti-Helicobacter therapy, methods and procedure for diagnostics and eradication therapy ofН. pyloriinfection.Key points. Chronic gastritis caused byН. pyloriinfection, including asymptomatic persons, may be considered as an indication for eradication therapy of Н. pylori as etiological therapy and opportunistic screening for gastric cancer prevention. Indications, for obligatory anti-Helicobacter therapy include peptic ulcer, gastric MALT lymphoma, early gastric cancer (EGC) with endoscopic resection. H. pylori primary diagnostics methods include¹³C-urea breath test,H. pyloristool antigen lab test, rapid urease test and serological method. The serological method cannot be used after anti-Helicobacter therapy.In RussiaH. pyloristrains' resistance to clarithromycin does not exceed 15 % in most regional studies. The first line therapy forН. pyloriinfection eradication is the standard triple therapy including a proton pump inhibitor (PPI), clarithromycin and amoxicillin, enhanced with bismuthate tripotassium dicitrate. A classic four-component therapy based on bismuthate tripotassium dicitrate or quadrotherapy without bismuth drug products which includes PPI, amoxicillin, clarithromycin and metronidazole, may be used as alternative to the first line eradication therapy. The standard triple therapy may be prescribed for 14 days only in those regions, where it has been proven to be effective. Quadrotherapy with bismuthate tripotassium dicitrate is also used as main second line therapy in case of standard triple therapy, bismuth enhanced standard triple therapy or combined therapy failure. Another second line therapy includes PPI, levofloxacin and amoxicillin, to which a bismuth-containing drug product may be added. The third line therapy is selected individually based on previously used treatment settings.Conclusion. In each case ofH. pyloriinfection the decision for eradication therapy should be made, which is especially relevant as eradication ofH. pylorihas been recognized as an effective measure for the prevention of gastric cancer.

Objective. To study in vitro activity of antimicrobials against clinical isolates from patients with communityacquired urinary tract infections (UTIs) in different regions of Russia in 2017–2018. Materials and Methods. A total of 1052 Enterobacterales isolates collected in the Russian Federation as part of a multicenter, prospective, epidemiological study of the antimicrobial resistance of uropathogens causing community-acquired UTI in different subsets of patients (“DARMIS-2018”) were included in the analysis. Uropathogens were isolated from children and adults of both sexes in all age groups with acute (and recurrences of chronic) community-acquired UTIs, including pregnant women with asymptomatic bacteriuria in 32 centers of 24 cities of Russia in 2017–2018.

Inappropriate antibiotic use in normally self-limiting acute respiratory tract infections (RTIs), such as sore throat and the common cold, is a global problem and an important factor for increasing levels of antibiotic resistance. A new group of international experts—the Global Respiratory Infection Partnership (GRIP)—is committed to addressing this issue, with the interface between primary care practitioners and their patients as their core focus. To combat the overuse of antibiotics in the community, and facilitate a change from prescribing empiric antibiotic treatment towards cautious deferment combined with symptomatic relief, there is a need to introduce and enhance evidence-based dialogue between primary care practitioners and their patients. Communication with patients should focus on the de-medicalisation of self-limiting viral infections, which can be achieved via a coherent globally endorsed framework outlining the rationale for appropriate antibiotic use in acute RTIs in the context of antibiotic stewardship and conservancy. The planned framework is intended to be adaptable at a country level to reflect local behaviours, cultures and healthcare systems, and has the potential to serve as a model for change in other therapeutic areas.

Community-acquired pneumonia is one of the most common acute infectious diseases that has a significant share in the structure of mortality from respiratory diseases. It is extremely important to select rational antibiotic therapy which ensures optimal clinical efficacy, improved outcome, reduced rate of antibiotic resistance selection, and minimization of side effects.Methods. The target audience of these clinical recommendations are therapists, general practitioners, pulmonologists, anesthesiologist-resuscitators, and clinical pharmacologists. Each thesis-recommendation about diagnostic and therapeutic procedures has been scored according to the scale of classes of recommendations from 1 to 5 and A, B, C scale of the levels of evidence. The clinical recommendations also contain comments and explanations to these theses, algorithms for the diagnosis and treatment, and reference materials on the use of antibacterial drugs and microbiological (culture) tests.Conclusion. The presented clinical guidelines cover current information about the etiology, clinical manifestations, diagnosis and treatment tactics for community-acquired pneumonia. The presented clinical guidelines have been approved by the Scientific and Practical Council of the Ministry of Health of the Russian Federation in 2021.
