    Covid-19-associated cardiac damage in patients on maintenance hemodialysis Case reports and review of the literature

    No full text
    A brief review of current publications about incidence, outcomes and mechanisms of cardiovascular complications in patients with the new coronaviral disease (COVID-19) is given. The possibility of direct deleterious viral effect on the myocardium, negative consequences of cytokine storm, the role of hypoxemia complicating acute respiratory distress syndrome (ARDS), myocardial infarction 1,2 type (MI 1, 2), hypercoagulation, systolic disfunction of right ventricle due to ARDS, recurrent pulmonary embolism (PE) and cardiotoxic effects of drug therapy is discussed. Three case reports of cardiac injury in patients on maintenance hemodialysis (MHD) with COVID-19 are presented. The fi rst case demonstrated MI 2 type due to ischemic imbalance in a patient with severe ARDS in the absence of obstructive coronary arteries lesion. The second case represented coexistent affection of heart as a result of viral myocarditis and cardiotoxic effect of Azithromycin and Plaquenil co-administration. The viral myocarditis was proven by postmortem histological and immunohistochemical tests. The third case demonstrated the diagnostic quest in a patient with recurrent dyspnea due to sequential severe ARDS, viral hemorrhagic exudative pericarditis with cardiac tamponade and PE progression. Currently three basic phenotypes of cardiac injury are distinguished: permanent elevation of myocardial damage markers, MI 1, 2 Type and viral myo/pericarditis. Of note, the course of COVID-19 in patients on MHD is more complicated in comparison with the general population. The initial vulnerability of these patients is determined not only by severe co-morbidity. Some interconfounding pathophysiological processes same to COVID-19 are critically important for the understanding of the current state of the art. The crucial role of persistent chronic infl ammation, coagulopathy, pulmonary hypertension, permanent hemodynamic stress and fl uctuation of volemic status should also be taken into consideration. MHD by itself is a powerful risk factor which overburdens the course of COVID-19

    Low-noise macroscopic twin beams

    No full text
    Applying a multiphoton-subtraction technique to the two-color macroscopic squeezed vacuum state of light generated via high-gain parametric down-conversion we conditionally prepare a different state of light: bright multimode low-noise twin beams. A lower noise in the sum of the photon numbers opens a possibility to encode information into this variable while keeping the nonclassical character of the state. The obtained results demonstrate up to eightfold suppression of noise in each beam while preserving and even moderately improving the nonclassical photon-number correlations between the beams. The prepared low-noise macroscopic state, containing up to 2000 photons per mode, is not among the Gaussian states achievable through nonlinear optical processes. Apart from that, we suggest a method for measuring quantum efficiency, which is based on the Fano factor measurement. The proposed technique substantially improves the usefulness of twin beams for quantum communication and metrology

    Risk factors of adverse outcome of COVID-19 and experience of Tocilizumab administration in patients on maintenance hemodialysis due to diabetic kidney disease

    No full text
    BACKGROUND: Patients with Type 2 Diabetes (T2DM) and patients on maintenance hemodialysis (MHD) are at a high risk of adverse clinical course of COVID-19. To date, the causes of high mortality in these groups are not fully understood. Data about peculiarity of clinical course and Tocilizumab (TCZ) administration in patients with T2DM receiving MHD due to outcome of diabetic kidney disease (DKD) are not yet highlighted in current publications.AIMS: Identification of risk factors (RF) of adverse COVID-19 outcome and evaluation of TCZ administration in patients with T2DM receiving MHD due to DKD.MATERIALS AND METHODS: The patients treated in Moscow City Hospital No52 were included in retrospective observational study. The observation period was from 04.15 to 07.30 2020. The study endpoints were the outcomes of hospitalization — discharge or lethal outcome. Data were collected from electronic medical database. The following independent variables were analysed: gender, age, body mass index, time from the onset of symptoms to hospital admission, cardiovascular and general comorbidity (Charlson Index, CCI), cardiovascular event (CVE) during hospitalization, treatment in ICU, mechanical ventilation (MV), degree of lung damage according to CT data, level of prandial glycemia at admission, MHDassociated parameters (vintage, type of vascular access, frequency of complications). The autopsy reports were evaluated for the purpose of lethal structure investigation. In a subgroup treated TCZ the time from symptoms onset to TCZ administration and number of laboratory indicators were evaluated.RESULTS: 53 patients were included, mean age 68 ±9 y, males — 49%. General mortality in observation cohort was 45%, mortality in ICU — 81%, mortality on MV — 95%. High cardiovascular and general comorbidity was revealed (mean CCI — 8,3 ±1,5 points). The causes of outcomes according to autopsy reports data: CVE 37,5% (among them — acute myocardial infarction during hospitalization), severe respiratory failure — 62,5%. The independent predictors of lethal outcome were: MV (OR 106; 95% CI 11,5–984; р <0,001), 3-4 degree of lung damage according to CT data (ОR 6,2; 95% CI 1,803–21,449; р = 0,005), CVE during hospitalization (ОR 18,9; 95% CI 3,631–98,383; р <0,001); CCI ≥10 points (ОR 4,33; 95% CI 1,001–18,767; р = 0,043), level of prandial glycemia at admission ≥10 mmol/l (ОR 10,4; 95% CI 2,726–39,802; р <0,001). For risk identification of upcoming lethal outcome a predictive model was created with the use of discovered RF as variables. The predictive value of this model is 92,45% (positive prognostic value — 96,5%, negative prognostic value — 87,5%).In TCZ treated subgroup the laboratory markers of adverse outcome were detected with application of correlation analysis. Among them: increasing level of CPR 24-48 hours before lethal outcome (r = 0,82), the reduction of lymphocytes count after TCZ administration (r = -0,49), increasing of leukocytes and further reduction of lymphocytes count 24-48 hours before lethal outcome (r = 0,55 и r = -0,52, resp.)).CONCLUSIONS: The number of RF of adverse COVID-19 outcome in patients with T2DM receiving MHD due to DKD are identified. CVE is one of the leading causes of mortality in study cohort. According to our experience the preventive (instead of rescue) strategy of TCZ administration should be used
