    Title translation Sepsis: from systemic inflammatory response syndrome to organ dysfunction.
    Abstract Based on their extensive experience and literature data, the author outlines difficulties in the morphological diagnosis of sepsis, by taking into account the current clinical classification. Occurring not only in sepsis and lacking clear morphological criteria, a systemic inflammatory response and organ dysfunction cannot be absolute signs of sepsis diagnosis. The author gives the morphological characteristics of the systemic inflammatory response, septic shock, and organ dysfunction.

    Title translation IgG4-related disease of the breast.
    Abstract IgG4-related disease is an immune-mediated disorder with tumor-like multiorgan involvement, elevated serum IgG4 level and specific histopathological appearance (lymphoplasmacytic infiltrate rich in IgG4+ plasma cells and storiform fibrosis). The article presents rare clinical and morphological observations of IgG4-related mastopathy in women with suspected tumor process. A strategy for the treatment of IgG4-related disease should be based on the results of pre-surgery histopathological examination, which may help to avoid unreasonable surgical intervention and choose glucocorticoids or rituximab as the first-line treatment.

    Title translation Heart damage in the combined types of systemic amyloidosis.
    Abstract The cardiovascular system is a common target of systemic amyloidosis (SA); amyloid light chain (AL) cardiac amyloidosis (AL-CA), the wild-type transthyretin (ATTRwt-CA), and mutant-type transthyretin (ATTRmt-CA) are the most studied types of SA. The literature describes only single cases of two types of SA in the same patient.
    Objective: To identify and determine the clinical and morphological characteristics of combined types of SA in patients with biventricular chronic heart failure (CHF).
    Material and methods: Eighty autopsy protocols for biventricular CHF deaths were retrospectively analyzed. Immunohistochemistry and confocal laser scanning microscopy (CLCM) with antibodies to amyloid A (AA), serum amyloid-P (SAP), prealbumin, and immunoglobulin kappa (κ) and lambda (λ) light chains were performed.
    Results: The myocardium showed a combination of different types of SA in 6 (7.5%) cases, including Alλ-CA+ATTR-CA, ALκ-CA+ATTR-CA, and AA-CA+ATTR-CA in 4, 1, and 1 cases, respectively. Macroscopically, the heart mass averaged 470±20 g; the thickness of the left and right ventricular myocardium was 1.5±0.2 and 0.4±0.1 cm, respectively; the interventricular septum averaged 1.2±0.2 cm; and the cardiac index was 0.008. The myocardium was dense, dark red with diffuse layers of whitish dense fibrous connective tissue; the heart cavities were enlarged. Microscopically, in 25% of cases, all heart parts had ALλ-CA that was characterized by massive amyloid deposits localized predominantly in the intramyocardial vessel wall, intermuscular connective tissue, and perivascularly. The myocardium also displayed small amyloid deposits of ALλ-CA and ATTR-CA in the intermuscular connective tissue and intramyocardial vessel wall. Amyloid deposits were located in different parts of the myocardium; there were also areas of co-localization of ALλ-CA+ATTR-CA.
    Conclusion: The combined types of SA occurred under the guise of coronary heart disease and the dilated cardiomyopathy phenotype. The combined amyloid AL-CA and ATTR-CA was generally localized in the interstitium and myocardial vessels. There were also small areas of co-localization of amyloid deposits, which were found mainly in the intramyocardial vessels.

    Title translation Anatomical pathology of novel coronavirus (COVID-19) infection. First impressions.
    Abstract To date, descriptive results of a clinical and morphological study of novel coronavirus COVID-19 infection, mainly of the lungs, have appeared. However, in other organs, primarily in the cardiovascular system, there are substantial structural changes that lead to multiple organ dysfunction and contribute to death.
    Objective: To analyze the thanatogenetic significance of novel coronavirus COVID-19 infection in different age and gender groups and to describe the main morphopathological manifestations in various organs.
    Material and methods: The investigators carried out a comprehensive analysis of 700 autopsies of people disease from the novel coronavirus COVID-19 infection, which included an examination of gross changes reflected in the autopsy protocols and forensic medical examination reports, as well as that of microscopic changes detected during histological examination of organs. Immunohistochemistry (IHC) using mouse or rabbit antibodies to CD34, CD68, EMA, Ki67, caspase-3, and VEGF was employed in some observations.
    Results: The novel coronavirus COVID-19 infection was the primary cause of death. Acute respiratory and pulmonary heart failure and multiple organ dysfunction became the leading thanatogenetic mechanisms in COVID-19. Cardiovascular disease, diabetes mellitus, and obesity were the most common diseases in patients with COVID-19. The most pronounced lung changes in COVID-19 were determined with a predominance of multiple total bilateral lesions of the lower lobes of the lungs, which was manifested by virus-induced changes in the parenchyma and stroma, as well as by microcirculation disorders. Acute dyscirculatory and ischemic changes in the parenchymal organs dominated in tissue damage caused by the virus.
    Conclusion: The changes in different organs of those who have died from the new coronavirus COVID-19 infection are stereotyped and include the manifestations of virus-induced action and a systemic inflammatory response with mainly microvasculature alteration, which leads to the development of coagulopathies and, accordingly, to total hypoxia.

    Abstract Importance: Assessment of the causative association between the COVID-19 and cause of death has been hampered by limited availability of systematically performed autopsies. We aimed to present autopsy-confirmed causes of death in patients who died with COVID-19 and to assess the association between thrombosis and diffuse alveolar damage consistent with COVID-19 (DAD).
    Methods: Consecutive forensic (n = 60) and clinical (n = 42) autopsies with positive post-mortem SARS-CoV-2 PCR in lungs (age 73 ± 14 years, 50% men) were included. The cause of death analysis was based on a review of medical records and histological reports. Thrombotic phenomena in lungs were defined as pulmonary thromboembolism (PE), thrombosis in pulmonary artery branches or microangiopathy in capillary vessels.
    Results: COVID-19 caused or contributed to death in 71% of clinical and 83% of forensic autopsies, in whom significant DAD was observed. Of the patients with COVID-19 as the primary cause of death, only 19% had no thrombotic phenomena in the lungs, as opposed to 38% amongst those with COVID-19 as a contributing cause of death and 54% amongst patients whose death was not related to COVID-19 (p = 0.002). PE was observed in 5 patients. Two patients fulfilled the criteria for lymphocyte myocarditis.
    Conclusions: Vast majority of all PCR-positive fatalities, including out-of-hospital deaths, during the SARS-CoV-2 pandemic were related to DAD caused by COVID-19. Pulmonary artery thrombosis and microangiopathy in pulmonary tissue were common and associated with the presence of DAD, whilst venous PE was rarely observed. Histology-confirmed lymphocyte myocarditis was a rare finding.

    Title translation A double blind placebo controlled randomized clinical trial of the efficacy and safety of pregabalin in induction of remission in patients with alcohol dependence.
    Abstract Aim: To study the efficacy of pregabalin for relapse prevention and reduction of drinking in patients with alcohol dependence.
    Material and methods: One hundred recently detoxified out-patients with alcohol dependence were randomly assigned to one of two treatment groups. Patients of the first group (n=50; 38 men, 12 women, age 43.0±1.27) received pregabalin (150 mg once a day at night time) for 3 months, while patients of the second group (n=50; 45 men, 5 women, age 45.92±1.4) received identically looking placebo. All patients received standardized manualized weekly counseling (medical management). Drinking was measured on the weekly basis with Time Line Follow Back technique and GGT enzyme activity. Also, craving for alcohol, depression, and anxiety were measured weekly with the number of scales.
    Results: Kaplan-Meier survival analysis demonstrated significantly higher retention in treatment and in remission in the pregabalin group (lower drop out and relapse rate) mediana (CL)-12 (10.4-13.6) weeks in the pregabalin group vs. 6 (4.5-7.5) in the placebo group, Log Rank Mantel-Cox test = 0.005). Proportion of patients, who completed treatment in the pregabalin group, was significantly higher compared to the placebo group: 50% vs. 24%. Mean duration of participation in the treatment program was also higher in the pregabalin group: 9.1±0.5 weeks vs. 7.1±0.5 in the placebo group. General linear model demonstrated the significant treatment group effect on: (1) total alcohol consumption (TAC) (mean grams of alcohol per day) with lower TAC in the pregabalin group and (2) on the number of heavy drinking days (NHDD) with lower NHDD in the pregabalin group. Mean NHDD per patient for the period of participation in the study was lower in the pregabalin group (3.6±0.7 vs. 6.4±0.8; p=0.009), while the mean number of abstinent (sober) days was higher (55.9±3.6 vs. 40.0±3.3; p=0.001). No significant differences between the two groups were found in the scores on craving for alcohol, depression and anxiety scales. GGT activity was also similar in both groups throughout the study with no significant between group differences. The rate of adverse events (sleepiness, dizziness, and headache) was insignificantly higher in the pregabalin group compared with the placebo group. All adverse events were mild, gradually disappeared, and did not require any medication.
    Conclusion: Results of this study provide evidence that pregabalin in a low dose of 150 mg per day is an effective and safe medication for relapse prevention and reduction of drinking in patients with alcohol dependence.

    Title translation Dual diagnosis: depression and alcohol use disorder.
    Abstract A combination of depression and alcohol use disorder (AUD) is a typical and most common example of a dual diagnosis at the intersection of general psychiatry and addiction psychiatry. A comorbidity of depression and AUD is more common than it can be brought about by mere coincidence, which might be explained to some extent by the synergetic effect of both diseases, with each of them complicating the course and worsening the prognosis of the other. Treatment protocols for patients with depression and comorbid AUD include antidepressants, specific medications for alcohol dependence, and psychotherapy. The first-line antidepressants in the treatment of patients with a comorbid combination of depression and alcohol use disorder, as in other clinical situations implying use of antidepressants, are selective serotonin reuptake inhibitors (SSRIs). Fluvoxamine has certain advantages over the other SSRIs in the treatment of patients with a depression and comorbid AUD.

    Abstract Introduction. Organ lesions due to the new coronavirus infection are determined by several factors: direct cytopathic effect of SARS-CoV-2, release of an unbalanced amounts of proinflammatory cytokines leads to systemic damage of the vascular endothelium and increasing hypoxia. These factors in total result in organ dysfunction.Methods and materials. We examined 96 pathological studies’ protocols of patients who died from the PCR-confirmed new coronavirus infection. Histological slides stained with hematoxylin and eosin were also analyzed.Results. Macroscopical and microscopical changes seen mostly in lungs, myocardium and other internal organs were described. We reviewed main causes of death (pulmonary and cardiopulmonary failure, multiple organ dysfunction syndrome) and most common concomitant diseases (diabetes mellitus, essential hypertension, obesity). The morphological features of diffuse alveolar damage in the acute and proliferative phases were described in detail. Taken together with the synchronous involvement of the microvasculature in the pathological process it became the main cause of death. The most severe structural changes in lungs were seen after 20 days of disease. These changes were correlated with dysregenerative metaplastic and dysplastic processes. Processes of disturbed regeneration reflect both the severe viral transformation of the alveolar epithelium and the fact that regeneration developed under mechanical ventilation.
