[Mental disorders associated with acute COVID-19: clinical picture, therapy approaches]. / Psikhicheskie rasstroistva, assotsiirovannye s ostroi fazoi techeniya COVID-19: klinika, podkhody k terapii.

BACKGROUND: The purpose is to study the structure of clinical manifestations of mental disorders in the acute period of COVID-19 among patients, who were hospitalized with a new coronavirus infection and their relations with the severity of the immune response, to assess the efficacy and safety profile of the spectrum of used psychopharmacotherapy. MATERIAL AND METHODS: A study was conducted of patients, hospitalized to the department of infectious diseases and repurposed for COVID-19 clinical departments with a diagnosis of COVID-19 (compliance with the criteria for ICD-10: U07.1) from September 2020 to March 2021. Study design: single center opened retrospective cohort study. The main group is consisted of 72 patients, average age - 71 [56.0; 81.0] years, the part of women - 64.0%. The control group (n=2221) was formed from those hospitalized in the same period with a diagnosis of U07.1 without mental disorders during the hospitalization period, average age 62 [51.0; 72.0] years, the part of women - 48.7%. Mental disorders were diagnosed in accordance to ICD-10 criteria, the following peripheral markers of inflammation, that were evaluated: neutrophils, lymphocytes, platelets, ESR, C-reactive protein, interleukin; also coagulogram indicators: APTT, fibrinogen, prothrombin time, D-dimers. RESULTS: In the following range of mental disorders were identified: a depressive episode (ICD-10 F32) by 31 patients, by 22 - a disorder of adaptive reactions (ICD-10 F43.2), by 5 - delirium not caused by alcohol or other psychoactive substances (ICD-10 F05), by 14 - mild cognitive impairment caused by damage and disfunction of the brain or somatic diseases (ICD-10 F06.7). In comparison with the control group, these patients showed a statistically significant (p<0.001) increasing the level of inflammatory markers (CRP, IL-6) and changes in the coagulogram. and anxiolytic drugs were used most often. Regarding psychopharmacotherapy, drugs from the group of atypical antipsychotics - quetiapine was prescribed in 44% patients in average dose 62.5 mg per day, and Melatonin receptor type 1 and 2 agonist and antagonists of serotonin 5-HT2C receptors: agomelatine was prescribed in 11% patients in average dose 25 mg per gay. CONCLUSION: The results of the study confirm the heterogeneity of the structure of mental disorders in the acute form of coronavirus infection, revealing the relations between the clinical picture and laboratory parameters of the immune response to systemic inflammation. Recommendations are given for the choice of psychopharmacotherapy, in conformity with the peculiarities of pharmacokinetics and interaction with somatotropic therapy.

DRIFT OF INFLUENA A(H3N2) VIRUS: BIOLOGICAL, ANTIGENIC AND GENETIC PROPERTIES IN EPIDEMIC SEASON 2016-2017 IN RUSSIA AND COUNTRIES OF THE NOTHERN HEMYSPHERE.

The article presents the features of the influenza virus circulation for the period from October 2016 to May 2017 in some territories of Russia collaborating with the D.I. Ivanovsky Institute of Virology, Federal State Budgetary Institution "N.F. Gamaleya Federal Research Centre for Epidemiology and Microbiology", Ministry of Health of the Russian Federation. One of the 2016-2017 season's peculiarities in Russia and countries of the Northern hemisphere was the earlier start of an increase in ARD morbidity with peak indexes reached towards the end of December 2016 - January 2017. First, influenza A(H3N2) virus was predominant; then, it was followed by influenza B virus activity observed until the end of the season. The indexes of morbidity were higher than in the previous season, while the rates of hospitalization and mortality were lower, lethal cases being detected in persons 65 years old and older. Epidemic strains of influenza A(H3N2) virus belonged to 3c.2a genetic group, reference strain A/Hong Hong/4408/2014, and its subgroup 3c.2a1, reference A/Bolzano/7/2016, that are antigenically similar. Strains of influenza B virus were antigenically similar to the B/Brisbane/60/2008 vaccine virus. Strains were sensitive to oseltamivir and zanamivir. The share participation of non-influenza ARI viruses was similar to preliminary epidemic seasons. WHO has issued recommendations for influenza virus vaccines composition for 2017-2018 for the Northern hemisphere.

In the 2015-2016 epidemic season, there were dominant influenza A(H1N1)pdm09 strains (over 90%) among the circulating influenza viruses in most countries of the Northern Hemisphere and in Russia. A study of the antigenic properties of influenza A(H1N1)pdm09 strains revealed no differences in those of vaccine virus. Sequencing showed that there were amino acid substitutions in hemagglutinin (receptor binding and Sa sites) and in the genes encoding internal proteins (PA, NP, M1, and NS1). The rise in the incidence in the Russian Federation, which was etiologically associated with influenza viruses, was registered in January-February 2016 with its maximum being observed at 4-5 weeks of 2016. Within the framework of the epidemiological surveillance of circulating influenza viruses in the Russian Federation, which was conducted by the WHO European Office, the D.I. Ivanovsky Institute of Virology, Honorary Academician N.F. Gamaleya Federal Research Centre for Epidemiology and Microbiology, Ministry of Health of Russia, and the Research Institute of Influenza, Ministry of Health of Russia, monitored at the Infectious Diseases Hospital One (IDH-1), Moscow Healthcare Department. Among 1491 examinees, influenza was verified in 104 (21.3%) adults, 208 (42.5%) pregnant women, and 177 (36.2%) children. Influenza A(H1N1)pdm09 was more often diagnosed in the age group of 15-40 years (63.7%); the proportion of influenza patients aged over 50 years increased (22.1%). Most adult patients had moderate influenza; pneumonia complicated the disease in 27.4%. Influenza in the pregnant women was complicated by pneumonia in 4.8% of cases. Influenza was more frequently diagnosed in infants and preschool children aged 0 to 3 years (42.9%), 4 to 6 years (41.2%), and older (15.9%), namely: 7-9 years (10%) and 10-12 years (5.9%). Influenza in the children was complicated by acute tonsillitis (19.4%) and varying degrees of laryngeal stenosis (12.4%). Bronchial obstructive syndrome developed in 2.5%, the rate of pneumonia was 6.2%. Antiviral therapy (AVT) in the early stages of the disease reduces the risk of its severity, the frequency of secondary complications, and the duration and degree of clinical symptoms of influenza. AVT with oseltamivir, zanamivir, imidazolyl ethanamide pentandioic acid (ingavirin), and interferon-a2b (viferon) has been performed in the patients hospitalized at Moscow IDH-1 in the 2015-2016 epidemic season.
