Coronavirus Infection

An outbreak of coronavirus disease CoViD-19, caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in a short period of time led to a global public health emergency worldwide. The difficult epidemiological situation associated with the rapid increase in the number of patients and the high mortality rate, as well as the need to overcome the consequences of the pandemic as soon as possible, have become an important challenge for science. The special attention of scientists is focused on in-depth study of the pathogenetic mechanisms of coronavirus infection, which is important for the development of antiviral drugs and vaccines to combat CoViD-19. To penetrate the target cells the virus uses receptors, expressed in various tissues of the organism, the main of which is angiotensin-converting enzyme 2 (ACE2). Virus replication is regulated by a lot of factors and causes abrupt morphological and physiological changes in cells. SARS-CoV-2 disrupts the regulation of inflammatory signaling pathways that generate a cytokine "storm", causes multisystem disorders and a life-threatening condition – acute respiratory distress syndrome. An important component of pathogenesis and clinical manifestations of CoViD-19 are hemostasis disorders, activation of thrombosis and thromboembolic complications. This review provides certain data regarding the structure of SARS-CoV-2, routes of infection, defense mechanisms against pathogen invasion, features of the hemostasis system in coronavirus infection, intracellular signal transduction, and current strategies for the prevention and treatment of CoViD-19, which are aimed primarily at suppressing the replication of the virus, limiting its dissemination and reducing the immune response of organism in conditions of infection.

The article presents a review of the literature sources and results of a personal study. It was found that in our group, there were more persons aged 18–30 years among those who were in inpatient treatment, and among those who were treated in the ICU, the patients were aged 60 years or over. On average, patients who were treated in the ICU were admitted on the 6th day of illness. Most patients complained of dry or unproductive cough, moderate general weakness. Relatively more often moderate general weakness was registered in patients with a moderate course, and moderate and pronounced was typical for patients with a severe course (p < 0.05). Dyspnea was predominantly found in severely ill patients (in one-third of patients during exercise, in 17.7 % patients at rest). In patients with a non-serious course, a small number of patients had dyspnea on exertion (4.3 to 12.1 %). On admission, the average temperature was within normal or subfebrile, which predominated in patients with a moderate course (p < 0.05). With a mild course, half of the patients had a temperature within the normal range. Febrile fever was more often registered in the moderate and severe course. Pyretic body temperature was most typical for a severe course (p < 0.05). It is noteworthy that even in those patients who were treated in the intensive care unit, at admission a quarter of the patients had a normal temperature, and 41.2 % — subfebrile. On ave-rage, the duration of fever before admission in critically ill patients was 5 days, and in those who died — 2 days. Dry cough was significantly more common in severe patients (p < 0.05). In the mild course, only one-fifth of patients complained of dry or unproductive cough. In the moderate course, the dry or unproductive cough was symptomatic for one-third of patients. There was no significant difference in the frequency of complaints of sore throat (p > 0.05). On average, a respiratory rate on admission in critically ill patients did not differ between those who survived and those who died, while those who died more often presented with a respiratory rate of 30/min or more, tachycardia, and more reduced saturation values.

The article is devoted to the peculiarities of providing medical care for coronavirus infection in a university student who has been moved to an observatory organized in a hotel-type hostel of the university to prevent the spread of COVID-19 among students living in hostels. The article provides data on the positive experience of using dexamethasone in the treatment regimen for moderately severe disease, follow-up and examination data. The article considers the tactics of managing a patient with suspected COVID-19 in the presence of data for pneumonia according to computed tomography and clinical manifestations characteristic of a new coronavirus infection, which was later confirmed in the study of antibodies to SARS-CoV-2. The importance of round-the-clock medical monitoring of persons placed in the observatory, finding out the details of the epidemiological history from them, as well as determining the tactics of their treatment with limited hospitalization opportunities in a growing number of patients with severe manifestations of COVID-19 requiring inpatient treatment is emphasized. A new coronavirus infection can lead to a rapid deterioration of the condition in young patients, which is not always manifested by severe lung damage according to computed tomography data, but is characterized by persistent fever that cannot be stopped by antipyretics, as well as severe muscle pain, severe asthenia, which can be considered as clinical indicators of the development of hyperactive inflammatory syndrome. The use in the treatment regimen of intravenous dexamethasone at a dose of 0.1 mg / kg of body weight twice led to a rapid normalization of temperature, relief of all clinical symptoms and was not accompanied by any complications both in the early period of convalescence and 2 months after discharge from the observatory.

The susceptibility to the development and progression of inflammatory periodontal diseases, which depends on genetic and external factors (smoking, stress, oral hygiene), varies widely. In the development of these diseases, an important role is played not only by the presence of periodontal pathogenic microorganisms, but also by the presence of congenital or acquired immunodeficiency, immunoregulatory defects. The immune system plays a key role in the physiological and pathological processes of periodontal tissues. In this regard, IL17, produced by CD4+ Th cells, which has both Pro-inflammatory and protective activity, is of particular interest in the pathogenesis of periodontitis. The aim of study was to identify the relationship between polymorphic loci of the IL-17A (rs2275913) and MMP-1 (rs1799750) genes and clinical manifestations of chronic periodontitis in petrochemical workers. Dental examination was performed in 92 ethylene oxide production workers with chronic periodontitis and 74 patients with chronic periodontitis who did not come into contact with chemical factors (control group). Genotyping of polymorphisms rs2275913 of the IL17A gene and rs1799750 of the MMP1 gene was performed by allele-specific real-time polymerase chain reaction (PCR). Hygienic assessment of the degree of air pollution of the working area with harmful substances was carried out by gas chromatography according to the guidelines for the determination of harmful substances in the air № 5098-89, № 3119-84. When comparing the results of studies of both groups, there were no statistically significant differences in the frequency distributions of allelic variants and genotypes of the IL-17A and MMP-1 genes. The AA/AG genotypes of the IL-17A gene were associated with an increased risk of severe disease compared to the GG genotype in workers in the main group (OR=6.1; 95% CI 1.33-28.5; p=0.021) and in the control group (OR=7.26; 95% CI 1.34-39.25; p=0.016). Carriers of the A allele in the control group increased the risk of severe chronic periodontitis by 2.4 times compared to carriers of the G allele (OR=2.41; 95% CI 1.19-4.87; p=0.014). During the dental examination of employees of the ethylene oxide plant, the clinical course of periodontal diseases was more severe in comparison with the control group, and the number of patients with severe periodontitis was twice as high. It was found that the AA/AG genotypes of the IL-17A gene and the carrier of the A allele are associated with increased susceptibility to the development of severe chronic periodontitis. The association between the MMP-1 gene polymorphism and the risk of severe forms of chronic periodontitis has not been established. A risk factor for the development of inflammatory periodontal diseases in employees of the petrochemical complex is a complex of harmful production factors.

Background: In the current coronavirus disease 2019 (COVID-19) pandemic, health systems are struggling to prioritize care for affected patients, however, physicians globally are also attempting to maintain care for other lessthreatening medical conditions that may lead to permanent disabilities if untreated. Idiopathic intracranial hypertension (IIH) is a relatively common condition affecting young females that could lead to permanent blindness if not properly treated. In this article, we provide some insight and recommendations regarding the management of IIH during the pandemic. Methods: The diagnosis, follow-up, and treatment methods of IIH during the COVID-19 pandemic period are reviewed. COVID-19 as a mimic of IIH is also discussed. Results: Diagnosis and follow-up of papilledema due to IIH during the COVID-19 pandemic can be facilitated by nonmydriatic fundus photography and optical coherence tomography. COVID-19 may mimic IIH by presenting as cerebral venous sinus thrombosis, papillophlebitis, or meningoencephalitis, so a high index of suspicious is required in these cases. When surgical treatment is indicated, optic nerve sheath fenestration may be the primary procedure of choice during the pandemic period. Conclusion: IIH is a serious vision threatening condition that could lead to permanent blindness and disability at a relatively young age if left untreated. It could be the first presentation of a COVID-19 infection. Certain precautions during the diagnosis and management of this condition could be taken that may allow appropriate care to be delivered to these patients while minimizing the risk of coronavirus infection.

The Impact

: The novel coronavirus infection (COVID‐19) is a global public health emergency.Since its outbreak in Wuhan, China in December 2019, the infection has spread at an alarming rate across the globe and humans have been locked down to their countries, cities and homes. As of now, the virus has affected over 20million people globally and has inflicted over 7 lac deaths. Nevertheless, the recovery rate is improving with each passing day and over 14 million people have recuperated so far. The statistics indicate that nobody is immune to the disease as the virus continues to spread among all age groups; newborns to the elders, and all compartmentsincluding pregnant women. However, pregnant women may be more susceptible to this infection as they are, in general, highly vulnerable to respiratory infections. There is no evidence for vertical transmission of the COVID-19 virus among pregnant women, but an increased prevalence of preterm deliveries. Besides this, the COVID-19 may alter immune response at the maternal-fetal interface and affect the well-being of mothers as well as infants. Unfortunately, there is limited evidence available in the open literature regarding coronavirus infection during pregnancy and it now appears that certain pregnant women have infected during the present 2019-nCoV pandemic. In this short communication, we study the impact of the COVID-19 infection on vertical transmission and fetal outcome among pregnant women.

Background:ANCA-associated vasculitides (AAV) are a group of systemic vasculitis carrying a high risk of hospitalization because the multiorgan involvement, the acute nature of some clinical manifestations, the chronic but very disabling course of some other manifestations and finally the risk of severe infections due to chronic glucocorticoid and immunosuppressor administration. However, data on hospitalization due to ANCA-associated vasculitis are still scarce.Objectives:to estimate the rate of the first hospitalization or the death in patients suffering from AAV in the Italian region of Friuli Venezia Giulia (about 1,200,000 inhabitants) from year 2013 to 2017.Methods:integration of the information coming from many administrative databases were used to this end. The Regional Health Information System of Friuli Venezia Giulia was used as the source of information for this retrospective cohort study. The system covers the entire regional population and includes various electronic health administrative databases that can be linked with one another on an individual basis through a unique encrypted identifier. In particular, the following databases were matched: the database of the regional potential health care beneficiaries (including demographic information and the residential history of all of the subjects living in the region), the hospital discharge database, the database of exemptions from medical charges were used for this study, the database of the different regional laboratories. The population under study was selected based on the following inclusion criteria: patients were residents in Friuli Venezia Giulia and they had to carry the exemption code for AAV, including Granulomatosis with Polyangiitis (GPA), or Eosinophilic Granulomatosis with Polyangiitis (EGPA), or Microscopic Polyangiitis (MPA). This population was observed from 2013 to 2017. The coded event was the occurrence of the first hospitalization or the death. Also, all the hospitalization and their main discharge diagnoses were registered.Results:103 patient with AAV were identified. The number of patients with at least one hospitalization/death was 74/103 (71,8%). Seven patients died during the observation period (6,6%). The whole number of hospitalizations was 285 in 74 patients. 55/74 (74,3%) patients experienced more than one hospitalization. In the majority of the hospitalizations (119/285, 41,7%), the cause of hospitalization was directly attributable to the disease itself, while the second cause of hospitalization was the infections (26/285, 9,1%). In 10/103 patients (9,7%), an end stage renal disease was recorded as event. The presence of at least one positivity for ANCA antibodies was documented in 76/103 patients (73,8%), mainly in patients carrying GPA. Globally, the presence of ANCA antibody seems to be associated with greater likelihood of an event (p=0,07, log-rank test). The first event occurred in 50% of ANCA-positive patients within 180 days from diagnosis, while in 50% of ANCA negative patients in 859 days. 6 out of the 7 deaths occurred in ANCA positive patients.Conclusion:the rate of hospitalization in AAV is very high confirming the high health care burden of illness. The disease itself is often the cause of the hospitalization, as well as the infectious complication, highlighting the need for more effective treatments, and glucocorticoid sparing therapies. ANCA antibody may represent a biomarker of a more serious disease.Disclosure of Interests:Luca Quartuccio Consultant of: Abbvie, Bristol, Speakers bureau: Abbvie, Pfizer, Elena Treppo: None declared, Salvatore De Vita Consultant of: Roche, GSK, Speakers bureau: Roche, GSK, Novartis, Francesca Valent: None declared

Osteoradionecrosis (ORN) of the jaws and medication-related osteonecrosis of the jaws (MRONJ) are uncommon but serious diseases affecting the oral and maxillofacial region with clinically similar appearance but distinct pathophysiology. Management of ORN and MRONJ is inherently challenging and the treatment outcomes are unpredictable. The use of autologous platelet concentrates (APCs) to promote hard and soft tissue healing is well described in the literature, and the efficacy of leucocyte and platelet-rich fibrin (L-PRF) has been well documented in a number of clinical studies. The aim of this study was to present our treatment strategy and the outcomes of incorporating L-PRF as a surgical adjunct in management of ORN and MRONJ in our centre. Methods: eight cases of ORN and MRONJ were treated with a combination of sequestrectomy and L-PRF as a surgical adjunct. Results: the overall success was 87.5%. Using L-PRF as an adjunct, we were able to predictably manage ORN and MRONJ without causing significant morbidity. Conclusion: our experience shows that L-PRF may be used as a valuable and cost-effective adjunct to surgical management of ORN and MRONJ. However, due to a limited number of patients, and a short period of review, the true effectiveness of the method is yet to be demonstrated in a longer follow-up study including a greater number of patients, besides the inclusion of a control group.

Recently, we have witnessed an unprecedented increase in the number of patients suffering from respiratory tract illness caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The COVID-19 virus is a single-stranded positive-sense RNA virus with a genome size of ~29.9 kb. It is believed that the viral spike (S) protein attaches to angiotensin converting enzyme 2 cell surface receptors and, eventually, the virus gains access into the host cell with the help of intracellular/extracellular proteases or by the endosomal pathway. Once, the virus enters the host cell, it can either be degraded via autophagy or evade autophagic degradation and replicate using the virus encoded RNA dependent RNA polymerase. The virus is highly contagious and can impair the respiratory system of the host causing dyspnea, cough, fever, and tightness in the chest. This disease is also characterized by an abrupt upsurge in the levels of proinflammatory/inflammatory cytokines and chemotactic factors in a process known as cytokine storm. Certain reports have suggested that COVID-19 infection can aggravate cardiovascular complications, in fact, the individuals with underlying co-morbidities are more prone to the disease. In this review, we shall discuss the pathogenesis, clinical manifestations, potential drug candidates, the interaction between virus and autophagy, and the role of coronavirus in exaggerating cardiovascular complications.

Introduction. In March 2020, the World Health Organization declared the outbreak of the novel coronavirus infection (COVID-19) a pandemic. The pandemic also significantly affected all academic, scientific and educational activities. Material and methods. We compared the work of the urological departments of the private (Medical Center Avicenna, Novosibisk) and municipal (City Clinical Hospital No. 11, Barnaul) clinics, as well as the urogenital department of the Novosibirsk Research Institute of Tuberculosis of the Ministry of Healthcare of Russia for 6 months of calm 2019, and the first half of 2020, which coincided with the start of the COVID-19 coronavirus pandemic. Results. In March 2020, the urogenital department of the Novosibirsk Research Institute of Tuberculosis of the Ministry of Healthcare of Russia was redesigned into an observational one. In the first half of 2020, patients with malignant neoplasms, varicocele, chronic pyelonephritis, hydronephrosis, dropsy of the testicular membranes and with phimosis/paraphimosis were admitted to the urology department of the City Hospital No. 11 in Barnaul in the first half of 2020. On the contrary, statistically significant in 2020 the number of patients admitted for kidney abscess and acute prostatitis prevailed. It can be assumed that, due to the tense epidemic situation, patients postponed seeking medical attention until their condition required emergency intervention. In the Medical Center Avicenna (Novosibirsk) in the first half of 2020 the number of visits to the pediatric urologist significantly decreased, the inpatient and average bed-day decreased. On the contrary the total duration of the patients' stay in the day hospital has significantly increased, which is logically explained by the epidemic situation; there was a statistically significant decrease in the number of most operations and outpatient procedures. Conclusion. The new coronavirus infection has affected all spheres of human life, to a maximum extent on medicine. In the first six months, no unified approaches to the management of urological patients in epidemic conditions were developed; clinics worked according to internal standards. Our analysis showed that strict adherence to sanitary and hygienic standards and the implementation of anti-epidemic measures allows us to provide urological care to patients in full-even in such unfavorable conditions.

Purpose. To analyze a clinical case of fungal uveitis in a patient who has undergone COVID-19. Material and methods. A patient born in 1962 was admitted to the Kaluga branch of the MNTK with complains of blurred vision. From the anamnesis: in the first half of 2020, he was treated at the Kaluga branch of the MNTK with a diagnosis of complicated cataract, highly complicated myopia, PCRD, CCRD, pigmentary glaucoma; in the autumn of 2020, he suffered a coronavirus infection complicated by severe bilateral interstitial pneumonia, he was in the intensive care unit for 2 weeks. Results. During examination of the patient, the clinical picture and data of objective methods indicated the development of bilateral uveitis in the patient. A course of anti-inflammatory therapy was prescribed, and positive dynamics were achieved. But there was a sharp deterioration on the 10th day. Concilium was held: a fungal etiology of uveitis was suspected. The anterior chamber was washed, material from the anterior chamber was taken for bacterial culture. At the 3rd day the results of bacterial culture showed the growth of Candida albicans fungi. A multistage complex medical and surgical treatment was carried out. The outcome is encouraged however, the observation time is insufficient to draw final conclusions. Conclusion. The incidence of COVID-19 remains high, so ophthalmologists should remain vigilant, collect a careful anamnesis and expect an increase of the number of patients with intraocular fungal infection. Key words: uveitis; fungal infection; COVID-19.
