Relevance. The rapid spread of new pathogens inevitably leads to the occurrence of joint circulation with already known infectious agents, leading to the development of mixed infections. The simultaneous circulation of the pandemic coronavirus SARS-CoV-2 with a highly contagious measles virus leads to the development of mixed infections in people who have not been sick or vaccinated against measles. Aims. Review cases of co-infection with measles and COVID-19 in Moscow. Material and methods. A retrospective study of cases of measles and COVID-19 co-infection in three children with a description of the epidemiological and clinical picture of the disease. Results. In all observed children, the manifestation of the disease was typical for measles, the diagnosis of COVID-19 was established based on a laboratory study carried out in a hospital, which gave reason to count. That the infection with SARSCoV-2 occurred after the infection of children with measles. Conclusions. Different incubation periods can lead to several options for the development of co-infection. The similarity of clinical symptoms at the onset of the disease does not allow excluding a certain infection clinically, without laboratory verification.

Abstract Background In December 2019, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, Hubei, China. Moreover, it has become a global pandemic. This is of great value in describing the clinical symptoms of COVID-19 patients in detail and looking for markers which are significant to predict the prognosis of COVID-19 patients. Methods In this multicenter, retrospective study, 476 patients with COVID-19 were enrolled from a consecutive series. After screening, a total of 395 patients were included in this study. All-cause death was the primary endpoint. All patients were followed up from admission till discharge or death. Results The main symptoms observed in the study included fever on admission, cough, fatigue, and shortness of breath. The most common comorbidities were hypertension and diabetes mellitus. Patients with lower CD4+T cell level were older and more often male compared to those with higher CD4+T cell level. Reduced CD8+T cell level was an indicator of the severity of COVID-19. Both decreased CD4+T [HR:13.659; 95%CI: 3.235–57.671] and CD8+T [HR: 10.883; 95%CI: 3.277–36.145] cell levels were associated with in-hospital death in COVID-19 patients, but only the decrease of CD4+T cell level was an independent predictor of in-hospital death in COVID-19 patients. Conclusions Reductions in lymphocytes and lymphocyte subsets were common in COVID-19 patients, especially in severe cases of COVID-19. It was the CD8+T cell level, not the CD4+T cell level, that reflected the severity of the patient’s disease. Only reduced CD4+T cell level was independently associated with increased in-hospital death in COVID-19 patients. Trial registration Prognostic Factors of Patients With COVID-19, NCT04292964.

Abstract Objectives: Seasonal variation is possible in some medical conditions.Acute dacryocystitis is very disturbing clinical picture and can develop in any time of the year in patients with lacrimal duct obstruction. We aimed to investigate whether there is a seasonal relationship with the emergence of acute dacryocystitis.Material and Methods:The files of the patients who applied to the ophthalmology outpatient clinic with the complaints of tearing and discharge for five years and diagnosed with acute dacryocystitis were analyzed retrospectively. Age, gender, date of occurrence of the complaints and the date of diagnosis of acute dacryocystitis were recorded. In order to determine the seasonal relationship, the data regarding the number of cases who applied every month of the year were analyzed statistically by Rayleigh test.Results: The mean age of 60 patients (45 females, 15 males) included in the study was 54.70 ± 16.80 years. It was found that all patients were not equally likely to arrive at the hospital and the onset of their complaints throughout the months of the year (p <0.05). The frequency of applications was higher between May and August.Conclusion: There seems to be a seasonal relationship with the timing of the acute dacryocystitis. In our series, more acute dacryocystitis cases were encountered in the first spring-summer months. The reason for the increase of acute dacryocystitis cases in hot seasons of the year may be due to the increase in infectious agents in these seasons.

The purpose of the study was to study the clinical and psychopathological phenomenology of the initial stage of depressive disorders in the context of clinical pathomorphosis. Materials and methods. Features of clinical symptoms of the initial stage of depressive disorders in the comparative aspect in the context of clinical pathomorphosis based on the analysis of medical records of 236 patients who were treated for depressive disorders in 1971-1995 (ICD-9 codes 296.1, 296.3) and clinical examination of 245 patients with depressive disorders in 2015-2019 (ICD-10 codes F 31.3, F 31.4, F 32.0, F 32.1, F 32.2, F 33.0, F 33.1, F 33.2) are considered. Results and discussion. It was established that there is a predominance in the clinical picture of modern depressive disorders of low mood (in general in 91.4% of patients, 91.6% of men and 91.3% of women, p>0.05), dyssomnia (93.1%, 92.5% and 93.5%, respectively, p>0.05), anxiety, fear (84.5%, 78.5%, 89.1%, respectively, p<0.01), asthenia (82.4%, 77.6% and 86.2%, respectively, p>0.05), somatic vegetative symptoms (82.9%, 77.6% and 87.0%, respectively, p<0.01), apathy (78.8%, 69.2% and 86.2%, respectively, p<0.01) and ideas of self-humiliation and self-blame (69.8%, 72.9% and 67.4%, respectively, p<0.01), and the relatively low prevalence of obsessive symptoms (55.1%, 54.2% and 55.8%, respectively, p<0.05), emotional lability (51.0%, 54.2% and 48.6%, respectively, p<0.01) and cognitive impairment (45.3%, 43.9% and 46.4%, respectively, p<0.05) with a predominance of emotional lability and ideas of self-humiliation and self-blame in men, and manifestations of anxiety, fear, apathy, cognitive impairment, obsessive and somatic vegetative symptoms in women, which gives grounds to consider that the main predictors of depressive disorder at the initial stage of low mood are dyssomnia, anxiety fear, asthenia and somatic vegetative symptoms. The revealed features suggest the presence of a clinical pathomorphosis of depressive disorders. The clinical pathomorphosis of the initial stage of depressive disorders is in a significant reduction in the clinical picture of low mood, ideas of self-abasement and self-blame, emotional lability and cognitive impairment, and an increase in anxiety, fear, asthenia, apathy, obsessive symptoms and obsessive-compulsive symptoms, with significantly greater gender differentiation of clinical symptoms of depression. Conclusion. The identified patterns are embedded in the general trend towards polymorphism and clinical undifferentiation of modern depressive disorders, significant involvement of patients with sleep disorders, asthenic, apathetic and somatic vegetative symptoms, which requires revision of diagnostic strategies and individualization of diagnosis. The identified patterns can be used for early diagnosis of depressive disorders and prevention of depression

ABSTRACT Measles is a highly contagious respiratory virus infection, with typical clinical symptoms including maculopapular rash, fever, cough, coryza, and conjunctivitis. Despite implementation of widespread vaccination programs throughout the world, the rates of global morbidity and mortality are still considerable. This study was performed to design a reliable indirect enzyme-linked immunosorbent assay (ELISA) to measure measles-specific immunoglobulin M (IgM). First, human IgM was purified, and then an anti-IgM antibody was produced in rabbits and purified in a multistep process. The rabbit IgG against human IgM was conjugated with peroxidase. Measles virus-infected Vero cells produced viral antigen. One hundred serum samples from infants of 9 to 18 months of age, mostly vaccinated, were evaluated for determining the presence of specific IgM antibodies against measles virus. The samples were also evaluated for neutralizing antibodies against measles virus by a microneutralization test (MNT). By comparing the results of the ELISA with those of MNT, it was demonstrated that ELISA had a sensitivity and specificity of 100 and 92%, respectively. On the other hand, when the results obtained by our ELISA system were compared with those of an imported measles virus IgM ELISA kit (EIAgen; Adaltis Italia SPa, Bologna, Italy), a high level of agreement was shown (k = 0.926).

Research in the last decade has uncovered many new paramyxoviruses, airborne agents that cause epidemic diseases in animals including humans. Most paramyxoviruses enter epithelial cells of the airway using sialic acid as a receptor and cause only mild disease. However, others cross the epithelial barrier and cause more severe disease. For some of these viruses, the host receptors have been identified, and the mechanisms of cell entry have been elucidated. The tetrameric attachment proteins of paramyxoviruses have vastly different binding affinities for their cognate receptors, which they contact through different binding surfaces. Nevertheless, all input signals are converted to the same output: conformational changes that trigger refolding of trimeric fusion proteins and membrane fusion. Experiments with selectively receptor-blinded viruses inoculated into their natural hosts have provided insights into tropism, identifying the cells and tissues that support growth and revealing the mechanisms of pathogenesis. These analyses also shed light on diabolically elegant mechanisms used by morbilliviruses, including the measles virus, to promote massive amplification within the host, followed by efficient aerosolization and rapid spread through host populations. In another paradigm of receptor-facilitated severe disease, henipaviruses, including Nipah and Hendra viruses, use different members of one protein family to cause zoonoses. Specific properties of different paramyxoviruses, like neurotoxicity and immunosuppression, are now understood in the light of receptor specificity. We propose that research on the specific receptors for several newly identified members of the Paramyxoviridae family that may not bind sialic acid is needed to anticipate their zoonotic potential and to generate effective vaccines and antiviral compounds.
