Objective. To estimate the prevalence of S. pneumoniae serotypes in adults aged of 18 years and older, including healthy carriers and patients with acute otitis media (AOM), community-acquired pneumonia (CAP) and invasive pneumococcal infection (IPI). Materials and Methods. A total of 230 isolates of S. pneumoniae from 10 centers were included in the study from 01.06.2019 to 01.10.2019. Re-identification and typing using real-time PCR with 22 primer pairs were performed in the central laboratory (Institute of Antimicrobial Chemotherapy, Russia).

Objective. To perform a comparative analysis of clinical and food isolates of Listeria monocytogenes collected in the European part of Russia in 2018–2019. Materials and Methods. We used multilocus sequencing (MLST), supplemented by virulence loci, including fragments of internalin genes (MvLST, Multi-virulent-locus sequence typing), followed by phylogenetic analysis. Results. The main diagnoses for clinical isolates were prenatal and neonatal listeriosis and meningitis. Clinical isolates predominantly belonged to phylogenetic line II with the predominance of ST7, which was also the most abundant in food isolates.

The success in preventing hepatitis B virus and human papillomavirus infections by means of vaccination paves the way for the development of other vaccines to prevent sexually transmitted infections (STIs) such as gonorrhoea, syphilis, chlamydia, …

Objective. To evaluate Staphylococcus species diversity and methicillin resistance in nosocomial infections. Materials and Methods. Staphylococci isolated from blood, bronchoalveolar lavage fluid, cerebrospinal fluid, post-operative wound exudates, urine and other samples were identified to species level with MALDITOF mass-spectrometry. Methicillin resistance was evaluated according to EUCAST guidelines. Results. A total of 3239 consecutive Staphylococcus strains isolated in a tertiary-care medical centre, accumulating patients from all Russian regions were identified in 2016–2017 as 1460 (45.

Adverse drug reactions affecting gastrointestinal tract, quite often with the development of antibioticassociated diarrhea, are the most common undesirable effects of antibiotic therapy in outpatient practice. This review provides modern approaches …

Objective. To study management of patients with peptic ulcer based on outpatient card data and to evaluate changes in methods for diagnosis of H. pylori and treatment prescriptions compared with 2004– 2005. Materials and Methods. A total of 100 outpatient cards of patients aged 18 years and older who came to outpatient clinic visit for peptic ulcer over the period of 2015–2018 were analyzed. The results of this study were compared with the data from the pharmacoepidemiological study «Ulcer», which was performed in 2004–2005 in Smolensk.

This article summarizes data on etiology, epidemiology and clinical presentation of acute liver failure. The review provides statistics on the incidence rates of acute liver failure in patients with different underlying diseases, describes the most …

Objective. To assess the incidence rate, risk factors and treatment outcomes of mucormycosis in children with hematological malignancies in the large tertiary hematology/oncology center. Materials and Methods. A total of 16 children (9 males/7 females) with mucormycosis were enrolled in a single-center, retrospective study over the period of 2012–2018. All patients had an underlying diagnosis of acute leukemia. Mucormycosis was diagnosed at the different timepoints after chemotherapy (CT) or hematopoietic stem cell transplantation (HSCT) in 15 cases and before CT in 1 case.

This paper discusses an etiology, patient characteristics, and antimicrobial resistance surveillance data, as well as other factors which help to determine indications for administration and choice of antibiotics for the treatment of patients with …

Objective. To compare the Quick Sequential (Sepsis-Related Organ Failure Assessment (qSOFA), National Early Warning Score (NEWS) and Systemic Inflammatory Response Syndrome (SIRS) scores value in predicting poor outcomes in emergency department patients with/without infection in Russia. Materials and Methods. This prospective observational study included data from 270 patients, of whom 132 (48.8%) patients had an infection and 138 (51.2%) did not have an infection. Comparison of areas under the ROC-curves (Receiver Operating Characteristic Curve) for the qSOFA, NEWS and SIRS scores in predicting the composite outcome (death and/or length of intensive care unit stay >1 day) was performed.
