Organization of microbiologic monitoring in epidemiologic surveillance of community-acquired pneumonia

The article deals with the results of the microbiological monitoring during the observation of the patients with community-acquired pneumonia, who have been admitted to a hospital therapeutic department. The quantitative criteria for assessing the etiological significance of microorganisms isolated from sputum have been proposed. The microbial landscape in the presence of community-acquired pneumonia have been studied, the prevalence of the fungi of the genera Candida, Streptococcus spp. and Staphylococcus spp have been found. The differences in the etiological structure of pneumonia caused by monocultures and the microbial associations have been identified. The microbial associations including 2 to 4 microorganisms have been examined. While evaluating the susceptibility of pathogens to antibiotics a high proportion of multi-drug resistant strains has been established. The fact that the microbial associations demonstrate a higher prevalence of antibiotic resistance compared to monocultures has been proved. So, it has been established that the microbial associations manifest a greater stability and a higher resistance to the disinfectants compared to the single-associant microbes that form these associations. We have proved the efficacy of the microbiological monitoring organized along with the observation of patients according to the developed parameters. The ways of improving the microbiological monitoring system for epidemiological surveillance of communityacquired pneumonia have been suggested

Clinical features of post-COVID-19 period. Results of the international register “Dynamic analysis of comorbidities in SARS-CoV-2 survivors (AKTIV SARS-CoV-2)”. Data from 6-month follow-up

Aim. To study the clinical course specifics of coronavirus disease 2019 (COVID-19) and comorbid conditions in COVID-19 survivors 3, 6, 12 months after recovery in the Eurasian region according to the AKTIV register. Material and methods.The AKTIV register was created at the initiative of the Eurasian Association of Therapists. The AKTIV register is divided into 2 parts: AKTIV 1 and AKTIV 2. The AKTIV 1 register currently includes 6300 patients, while in AKTIV 2 — 2770. Patients diagnosed with COVID-19 receiving in- and outpatient treatment have been anonymously included on the registry. The following 7 countries participated in the register: Russian Federation, Republic of Armenia, Republic of Belarus, Republic of Kazakhstan, Kyrgyz Republic, Republic of Moldova, Republic of Uzbekistan. This closed multicenter register with two nonoverlapping branches (in- and outpatient branch) provides 6 visits: 3 in-person visits during the acute period and 3 telephone calls after 3, 6, 12 months. Subject recruitment lasted from June 29, 2020 to October 29, 2020. Register will end on October 29, 2022. A total of 9 fragmentary analyzes of the registry data are planned. This fragment of the study presents the results of the post-hospitalization period in COVID-19 survivors after 3 and 6 months. Results. According to the AKTIV register, patients after COVID-19 are characterized by long-term persistent symptoms and frequent seeking for unscheduled medical care, including rehospitalizations. The most common causes of unplanned medical care are uncontrolled hypertension (HTN) and chronic coronary artery disease (CAD) and/or decompensated type 2 diabetes (T2D). During 3- and 6-month follow-up after hospitalization, 5,6% and 6,4% of patients were diagnosed with other diseases, which were more often presented by HTN, T2D, and CAD. The mortality rate of patients in the post-hospitalization period was 1,9% in the first 3 months and 0,2% for 4-6 months. The highest mortality rate was observed in the first 3 months in the group of patients with class II-IV heart failure, as well as in patients with cardiovascular diseases and cancer. In the pattern of death causes in the post-hospitalization period, following cardiovascular causes prevailed (31,8%): acute coronary syndrome, stroke, acute heart failure. Conclusion. According to the AKTIV register, the health status of patients after COVID-19 in a serious challenge for healthcare system, which requires planning adequate health system capacity to provide care to patients with COVID-19 in both acute and post-hospitalization period

The interaction of folate cycle enzyme genes and the risk of extrapyramidal side effects of antipsychotics

Personalized medicine means the selection of therapy for patients, taking into account the assessment of genetic risk factors for side effects. A number of studies show that folate metabolism disorders, including single nucleotide polymorphisms (SNPs) in the genes of folate-metabolizing enzymes, are more frequently detected in schizophrenic patients than in the general population. The role of SNPs of the key folate cycle enzymes in developing the extrapyramidal side effects of antipsychotics has not yet been studied, although there is evidence of their association with other movement disorders.Objective: to analyze the association between the carriage of SNP alleles of MTHFR 677C>T, MTR 2756A>G, and MTRR 66A>G and the severity of extrapyramidal side effects of antipsychotics in patients with schizophrenia.Patients and methods. The investigation included 61 patients with schizophrenia (according to the criteria for ICD-10 Code F20). All the patients took antipsychotics for at least 7 hospital days were examined using real-time polymerase chain reaction (PCR) with allele-specific primers, followed by detection for the carriage of SNP alleles of MTHFR 677C>T, MTR 2756A>G, and MTRR 66A>G. The standardized Simpson–Angus scale (SAS) was used to evaluate the severity of extrapyramidal symptoms; the PCR test results were unknown during their examination.Results and discussion. In the patients carrying a low-functional 677 T allele in the gene of the key folate cycle enzyme MTHFR, the severity of extrapyramidal side effects of antipsychotics was statistically significantly higher than in the carriers of the wild-type genotype: 13.27±5.10 versus 9.84±6.03 SAS scores, respectively (t=-2.40; p=0.020). In addition, the carriage of the wild allele A of SNP in the MTRR 66A>G gene (F=3.83; p=0.0283; pcorr.=0.043) is associated with the severity of extrapyramidal symptoms. There was a direct moderate correlation of the number of risk alleles at two loci with the total SAS score (r=0.51; p=0.00017).Conclusion. The polymorphic allele of MTHFR 677T and the wild allele of MTRR 66A can be regarded as risk alleles for the development of extrapyramidal side effects of antipsychotics
