FEATURES OF CLINICAL MANIFESTATIONS AND LABORATORY DIAGNOSIS OF TICK-BORNE RELAPSING FEVER CAUSED BY BORRELIA MIYAMOTOI IN THE NOVOSIBIRSK REGION
摘要
The clinical manifestations of tick-borne relapsing tick-borne fevers caused by Borrelia miyamotoi in the West Siberian Region remain little understood. Objective. To verify the diagnosis of borreliosis caused by B. miyamotoi in the dwellers of the Novosibirsk Region and to investigate its clinical and laboratory characteristics. Materials and methods. 415 patients hospitalized with fever occurring after a tick bite were examined. Hemogram readings and serum biochemical parameters were analyzed. B. miyamotoi DNA from the patients’ blood was revealed by two-round PCR; the results were confirmed by sequencing the detected PCR fragments. Results. Blood Asian type B. miyamotoi DNA was found in 9.6% of the examinees. The main manifestations of B. miyamotoi infections were fever and symptoms of intoxication in the absence of erythema migrans and signs of nervous system lesion. In borreliosis caused by B. miyamotoi, relative neutrocytosis and a stab shift in the white cell count were noted more frequently than those in Ixodes tick-borne borreliosis (p < 0.05). The increase in the activity of ALT and AST was slightly marked; the mean values of the transaminases were higher than those in the erythemal form of Ixodes tick-borne borreliosis (p < 0.05). Conclusion. The findings are the basis for including B. miyamotoi test-systems in a set of techniques for screening tick-borne infections.

EPIDEMIOLOGY OF PERTUSSIS IN THE YAROSLAVL REGION DURING PLANNED MASS IMMUNIZATION
摘要
Objective. To identify the regularities of the epidemic process of whooping cough during planned mass immunization for children in the Yaroslavl Region under the current sociodemographic conditions and to elaborate measures to reduce the incidence of this infection. Materials and methods. The authors performed a comparative retrospective epidemiological analysis of the incidence of pertussis, the demographic situation, and the quality of vaccination in the Yaroslavl Region, by using data from the state infectious diseases reports by the Directorate for the Yaroslavl Region, Russian Federal Service for Supervision of Consumer Rights Protection and Human Welfare, and those by the Russian Federal Service for Supervision of Consumer Rights Protection and Human Welfare, statistical observation forms No. 2 «Information on Infectious and Parasitic Diseases» and No. 6 «Information on Contingents of Children and Adults Vaccinated Against Infectious Disease» over 2004-2016. Results. Whatever the coverage and timeliness of immunization, whooping cough was shown to be characterized by common epidemiological patterns: long-term dynamics, periodic upsurges of morbidity rates, changes in the structure of morbidity, and pronounced territorial irregularity. It was established that the intensity of the epidemic process of pertussis and the features of its manifestations were largely determined by the demographic situation, the size of the pediatric population, social conditions, and the insufficient duration of postvaccination immunity. Thus, in 2016, the incidence of pertussis increased by 8.7% compared to 2015, amounting to 23.1 per 100,000 population, which was 4.1 times the average level in the Russian Federation (5.6 per 100,000 population). The highest morbidity rates were noted among infants under 1 year of age (206.5 per 100,000 babies of this age) and schoolchildren (167.8 per 100,000 children in this category). Conclusion. The features of the present-day epidemiology and clinical course of pertussis necessitate changing the vaccination tactics and introducing revaccination with acellular vaccines in children and adults. In order to protect newborns from whooping cough, it is advisable to promptly vaccinate all family members without a history of this infection, including adults. This will be able to protect a baby in the first 6 months of life before he/she develops postvaccination immunity.

OROPHARYNGEAL MICROBIOTA IN RESPIRATORY INFECTIOUS AND INFLAMMATORY DISEASES
摘要
Objective. To investigate the species and generic composition and antibiotic susceptibility of the oropharyngeal microbiota in respiratory infectious and inflammatory diseases. Subjects and methods. 189 patients with chronic rhinitis/chronic nasopharyngitis, allergic rhinitis, acute nasopharyngitis etc. were examined. Swabs were collected from the posterior pharyngeal wall and tonsils; the isolates were identified by classic physiological and biochemical tests. Antibiotic susceptibility was assessed by a disk diffusion method. Results. A total of 495 microbial isolates were obtained; 25 genera and 28 species were identified. There was a preponderance of Staphylococcus aureus (57.7%), Enterococcus spp. (49.2%), Streptococcus agalactiae (32.8%), Neisseria spp. (14.3%), and Streptococcus pyogenes (13.8%). Aminoglycosides, macrolides, and lincosamides versus other antibiotic groups demonstrated a low efficacy in vitro against all the mentioned bacterial species. Conclusion. Comparison of the antibiotic susceptibility ofS. aureus strains, which was discovered in 1998,2005, and 2016, indicates that the susceptibility to gentamicin has decreased over 20yearsfrom 85.1 to 39.6%, although doxycycline, azithromycin, lincomycin, and chloramphenicol demonstrated the lowest efficacy in vitro in 2005, and this indicator has considerably increased to date.

MYCOPLASMA INFECTION AFTER VITAL ORGAN TRANSPLANTATION IN THE EARLY POSTOPERATIVE PERIOD
摘要
Objective. To detect Mycoplasma species in solid organ transplant recipients following transplantation. Subjects and methods. Ninety-nine transplant recipients were examined for Mycoplasma infection after heart, liver, or kidney transplantation. The patients were divided into 2 groups: 1) 86 patients having a good postoperative period; 2) 13 patients whose postoperative period was poor. Mycoplasma antigens were determined by aggregate hemagglutination assay; antibodies were detected by the passive hemagglutination assay. Results. Markers of different Mycoplasma species were identified in patients after organ transplantation. In patients who had undergone orthotopic heart transplantation (OHT), Mycoplasma pneumoniae was identified almost twice more common than in those who had related liver fragments transplantation (RLFT): 54.5 ± 0.08 and 31.0 ± 0.09%, respectively (p < 0.05). Ureaplasma spp. also prevailed in patients who had undergone OHT versus those who had RLFT, but these data were not statistically significant (p > 0.05). Ureaplasma spp. was more frequently detected in Group 2 than in Group 1: its isolation frequency was 46.2 ± 0.14 and 36.0 ± 0.05%, respectively (p < 0.05). The isolation frequency of M. pneumoniae was 47.7 ± 0.05% in Group 1 and 30.8 ± 0.13% in Group 2 (p > 0.05). Conclusion. It is important to detect Mycoplasma not only for the prevention and treatment of its infection in the early in-hospital period, but also for the prevention of late complications.

ANTIBIOTIC RESISTANCE IN THE REAL PRACTICE OF AN INFECTIOLOGIST: RESULTS OF AN INVESTIGATION
摘要
Objective. To analyze the antibiotic susceptibility of the microflora isolated in the bacteriological examination of smears from the upper respiratory tract of patients with acute respiratory diseases requiring hospitalization. Materials and methods. 935 upper respiratory tract specimens from children and 312 ones from adults admitted to the Center for Prevention and Control of AIDS and Infectious Diseases, Ministry of Health of the Kabardino-Balkar Republic, with acute respiratory diseases were analyzed. The EUCAST disk diffusion method (version 4.0, June 2014) was used to evaluate the antibiotic susceptibility of microorganisms. Results. The antibiotic susceptibility of St. aureus and St. epidermitidis, Streptococcus spp., Streptococcus pneumoniae, Streptococcus pyogenes, Neisseria spp, and Klebsiella pneumoniae was determined. There was the most pronounced resistance to antibiotics, primarily cephalosporins and macrolides, used for the hospital empirical therapy of acute respiratory infections. Cotrimoxazole may be currently used only to treat Pneumocystis pneumonia. Conclusion. Antibiotic resistance is about 2-fold higher in children than in adults. It is worth refusing erythromycin, azithromycin, and oxacillin when treating scarlet fever. Only stratification in the use of antibiotics will be able to reduce the resistance.

ULTILOCUS SEQUENCING TYPING OF HAEMOPHILUS INFLUENZAE SEROTYPE b IN THE EPIDEMIOLOGICAL HIB-MENINGITIS SURVEILLANCE IN RUSSIA
摘要
Haemophilus influenzae serotype b bacteria belong to the common causative agents of purulent bacterial meningitis in children. An analysis of the information obtained using multilocus sequencing typing (MLST) allows genetic characterization of circulating pathogens and determination of the contribution of the representatives of these or those sequence types and clonal complexes in the epidemic process when retrospectively or prospectively assessing the epidemiological situation. The review provides an analysis of the results of using MLST to Russian H. influenzae serotype b isolates, which are available in the database http://pubmlst.org/hinfluenzae, and the epidemiological characteristics of the identified sequence types and clonal complexes.

EVALUATION OF THE SAFETY AND REACTOGENICITY OF THE COMBINED VACCINE PENTAXIM
摘要
Objective. To evaluate the reactogenicity and safety of the combined pentavalent vaccine against pertussis (acellular), diphtheria, tetanus, polio, and Haemophilus influenzae type b infection during revaccination at the age of 18 months. Materials and methods. One-month clinical observation was made in 200 children (64 healthy individuals and 136 patients with different background diseases, who had been vaccinated with Pentaxim; and the incidence of postvaccination complications was also analyzed. For safety assessment, the investigators calculated the frequency of recorded postvaccination complications per Pentaxim doses used in the city in children aged 3 months to 4 years in the period 2009 to 2016 and analyzed the registration rate of Hib meningitis and cases of meningitis of unknown etiology as compared to the number of combined vaccine doses used in this period. Results. The vaccination process was asymptomatic in 77% of the vaccinated; usual vaccination reactions were observed in 23% of cases (46 out of the 200 children), more frequently in children with a family history (38 (27.9%) of the 136 patients) than in the healthy children (8 (12.5%) of the 64 children); p < 0.05). Only 2 (1%) patients had strong reactions and a body temperature of above 38.6 0C. With the use of 334,804 vaccine doses, there was 1 case of Quincke’s edema, 1 case of febrile seizures, and 5 local allergic complications (1 case per 66,960 doses). According to the Directorate for Saint Petersburg, Russian Federal Service for Supervision of Consumer Rights Protection and Human Welfare, nearly 40% of the babies during the first year of life received combined vaccines with a Hib component in 2013-2014. The number of Hib meningitis cases decreased from 29 in 2009 to 5 in 2016; that of unspecified meningitis cases did from 27 to 3, respectively. Conclusion. The vaccine is characterized by a low reactogenicity and a high safety profile, indicated for children with different health states, and can control the invasive forms of Haemophilus influenzae type b infection.

VARICELLA: CLINICAL PRESENTATIONS, TREATMENT, PREVENTION
摘要
The current epidemic process is characterized by a rise in varicella incidence among both children and adults, which increases the risk of developing the disease in pregnant women and newborn infants. Polymerase chain reaction and enzyme immunoassay were used to confirm the etiology of varicella in a mother and his baby. There was a clear correlation between the time, at which exanthema appeared in pregnant women, and the severity and outcome of neonatal chickenpox in the newborn. The paper presents the symptomatology of varicella in pregnant women and neonatal chickenpox in relation to the time of fetal infection and to a physician’s policy to treat the mother and child, as well as existing methods to prevent this disease.
