Due to the current epidemiological situation caused by the spread of the new SARS-CoV-2 coronavirus, in March 2020 several Moscow hospitals were completely or partially redesigned to receive patients with community- acquired pneumonia.Purpose. The aim of the survey is to analyze clinical, laboratory and radiological data in patients with coronavirus infection at the early stages of its spread in Russia, and to clarify diseases for differential diagnosis mainly based on CT evidence.Materials and methods. We studied data from 21 patients with verified coronavirus infection admitted to the hospital for community-acquired pneumonia. Clinical symptoms, laboratory and physical indicators, as well as typical lung changes on the CT were evaluated.Results. Major clinical symptoms in coronavirus patients are fever (100%), cough (90.5%), shortness of breath (76.1%). Laboratory indicators showed increases in CRP (85.7%), leukocytosis (66.6%), and LDG (84.6%). According to CT, 95.2% of lung changes involved both sides, and 66.7% occurred in all lung fields. The sign of “ground glass” was observed in a 100% of the cases, its combination with the “paving stone” – in 61,9%, “ground glass” coupled with small areas of consolidations were detected in 33,3% of the cases. Changes such as nodules, cavities and massive areas of consolidation were not identified.Conclusion. On the basis of our own data we confirmed the main trends of diagnostics and clinical features, which were identified by authors from Asia and Europe, who faced this infection earlier, and also considered important CT characteristics useful for differential diagnosis of coronavirus lung damage and other lung diseases.

Abstract Background Talaromyces marneffei (TM) primarily infects patients with co-morbidities that cause immunodeficiency, but non-secretory myeloma (NSMM) is rare. TSM and NSMM are associated with fever, osteolysis, and swollen lymph nodes, thereby making it difficult for clinicians to make differential diagnosis. In this case, we describe TM infection coexisting with NSMM. Case presentation We retrospectively reviewed the case of a male (without human immunodeficiency virus infection) with fever, thoracalgia, swollen lymph nodes, and subcutaneous nodules who presented to the First Affiliated Hospital of Guangxi Medical University in February 2014. Chest computed tomography revealed patchy infiltration and positron emission tomography/computed tomography showed increased metabolic activity in the lower-right lung, lymph nodes, left ninth rib, and right ilium. Pathological examination of the lung, lymph nodes, subcutaneous nodules, and bone marrow showed no malignancy, he was diagnosed with community-acquired pneumonia. His clinical symptoms did not improve after anti-bacterial, anti-Mycobacterium tuberculosis, and anti-non-M. tuberculosis treatment. Later, etiological culture and pathological examination of the subcutaneous nodule proved TM infection, and the patient was re-diagnosed with disseminated TSM, which involved the lungs, lymph nodes, skin, bone, and subcutaneous tissue. After antifungal treatment, the patient showed significant improvement, except for the pain in his bones. Imaging showed aggravated osteolysis, and bone marrow biopsy and immunohistochemistry indicated NSMM. Thus, we conclusively diagnosed the case as NSMM with TSM (involving the lungs, lymph nodes, skin, and subcutaneous tissue). His condition improved after chemotherapy, and he was symptom-free for 7 years. Conclusion TM infection is rare in individual with NSMM. Since they have clinical manifestation in common, easily causing misdiagnosis and missed diagnosis, multiple pathological examinations and tissue cultures are essential to provide a differential diagnosis.

Summary. Aim. To analyze the features of differential diagnosis of urgent surgical pathology during a coronavirus infection pandemic. Materials and methods. The work is based on the analysis of the results of additional examination of 28 patients at the admission department, who sought medical help in an urgent manner. Results. The advantages and disadvantages of using instrumental methods for detecting atypical forms of coronavirus infection and acute abdominal pathology are analyzed. Based on this, a diagnostic algorithm was developed using express tests for the determination of COVID-19 and urgent ultrasound protocols, which made it possible to identify lung lesions without clinical symptoms in 8 (28.6 %) patients, and to confirm acute surgical pathology in 5 (17.9 %) patients. Conclusion. Еxamining patients with suspected acute abdominal pathology for the purpose of differential diagnosis with the gastrointestinal form of COVID-19, it is necessary to use rapid tests for detecting antibodies to coronavirus infection and sonographic examination of the abdominal organs (FAST protocol), chest organs (BLUE protocol).

В статье рассматриваются некоторые особенности выявления больных с «кишечной формой» новой коронавирусной инфекцией у пациентов хирургического профиля на уровне приемного отделения многопрофильного стационара. Данная тематика является весьма актуальной, так как после начала пандемии Covid-19 в 2020 году, было выявлено несколько отличающихся течением, форм заболевания, одной из которых и стала, так называемая «кишечная форма». Большой интерес обусловлен тем, что при данном виде течения патологического процесса практически отсутствуют характерные для Covid-19 симптомы - болезнь, зачастую, маскируется под клинику «острого живота», в виду чего в ряде случаев диагностика ложиться на плечи врачей хирургического профиля. Данная работа стала результатом попытки выявить основные закономерности развития и особенности «течения» у пациентов данной патологии, с выявлением основных клинических симптомов, которые могли бы своевременно помочь с адекватной дифференциальной диагностикой. Объектами исследования послужило 150 пациентов, мужчин и женщин, в возрасте от 19 до 79 лет, мужчин (n=91) и женщин (n=59). Все больные были разделены на 3 группы по 50 человек. В первую группу вошли больные, у которых была выявлена одна из существующих острых хирургических патологий. Вторую группу составили пациенты, у которых была диагностирована «кишечная форма» новой коронавирусной инфекции. В третью группу вошли пациенты, которые ранее уже перенесли Covid-19. В основу исследования лег подробное изучение всех жалоб пациентов. Так были установлены определенные различия между рядом жалоб у пациентов различных групп. Однако ведущим симптомом, заставившем всех больных обратиться в стационар, был болевой синдром. В дальнейшем в работе проведен комплексный анализ боли, ее характер и особенности локализации в зависимости от группы. Важной частью исследования стало также изучение общего анализа крови и биохимического анализа крови, с выделением основных показателей, способных оказать помощь в дифференциальной диагностике. В завершении исследования проводилось изучение данных УЗИ и методов специфической диагностики новой коронавирусной инфекции, позволяющих получить первичные данные о процессе формирования иммунитета после перенесенного Covid-19. Статья интересна прежде всего врачам, занимающимся первичным приемом пациентов в стационарах и поликлиниках The article discusses some of the features of identifying patients with "intestinal form" of new coronavirus infection in surgical patients at the level of the admission department of a multidisciplinary hospital. This topic is very relevant, since after the start of the Covid-19 pandemic in 2020, several different forms of the disease were identified, one of which became the so-called "intestinal form". The great interest is due to the fact that with this type of pathological process, there are practically no symptoms characteristic of Covid-19 - the disease is often disguised as an acute abdomen clinic, which means that in some cases, the diagnosis falls on the shoulders of surgical doctors. This work was the result of an attempt to identify the main patterns of development and features of the "course" in patients with this pathology, with the identification of the main clinical symptoms that could promptly help with adequate differential diagnosis. The objects of the study were 150 patients, men and women, aged 19 to 79, men (n = 91) and women (n = 59). All patients were divided into 3 groups of 50 people each. The first group included patients who had one of the existing acute surgical pathologies. The second group consisted of patients who were diagnosed with the "intestinal form" of a new coronavirus infection. The third group included patients who had previously suffered from Covid-19. The study was based on a detailed study of all patient complaints. Thus, certain differences were established between a number of complaints in patients of different groups. However, the leading symptom that made all patients go to the hospital was pain syndrome. In the future, a comprehensive analysis of pain, its nature and localization characteristics depending on the group was carried out. An important part of the study was also the study of a general blood test and a biochemical blood test, with the identification of the main indicators that can help in differential diagnosis. At the end of the study, the study of ultrasound data and methods of specific diagnostics of a new coronavirus infection was carried out, which make it possible to obtain primary data on the formation of immunity after the transferred Covid-19. The article is of interest primarily to doctors engaged in the primary admission of patients in hospitals and clinics

New coronavirus infection (COVID-19) viral pneumonia diagnosed by a complex assessment of the epidemiological history, clinical symptoms, radiological and laboratory tests. Radiologists often play a leading role in diagnosis of viral pneumonia, since they may encounter suspicious changes according to radiological studies before clinicians. However, in a number of diseases, including diseases of non-infectious non-viral etiology with a corresponding similar clinical symptoms, it may be difficult to correctly assess the changes detected by computed tomography. This study uses clinical cases to show the main differential diagnostic criteria for COVID-19 viral pneumonia and non-infectious lesions such as pulmonary edema, pulmonary embolism, acute hypersensitive pneumonitis, drug-induced pneumonitis, non-specific interstitial pneumonia, and adenocarcinoma. All patients were hospitalized based on the results of computed tomography, where a diagnosis of non-infectious non-viral lung injuries was established based on morphological and/or typical clinical symptoms, laboratory or radiological data. We examined clinical cases with radiological signs similar to viral pneumonia, such as areas of ground glass opacities with the presence or absence of areas of consolidation, as well as thickening of the lung interstitium with decreased lung attenuation (crazy paving symptom). In a difficult epidemiological situation, it is important for a radiologist to suspect the above-mentioned pathological conditions in patients who are urgently admitted to outpatient CT centers.

BACKGROUND. In the modern era, COVID-19 is the biggest problem facing doctors and scientists around the world. SARSCоV-2 is a multisystem infection that is not limited to lung damage and has the immuno-mediated effect of negative effects on organs and systems, including the kidneys. To date, there is no precise understanding of the pathogenesis of nephrological disorders in patients with COVID-19. Patients with chronic kidney disease (CKD) are a group of particularly high risk of CO-VID-19 infection and high mortality in the development of the disease.THE AIM: to evaluate the features of the course of a new coronavirus infection (COVID 19) in patients with acute kidney injury and terminal renal insufficiency.PATIENTS AND METHODS. The study of clinical, laboratory and instrumental parameters was carried out in 119 patients (67 men and 52 women) diagnosed with COVID-19. The average age of the patients was 63.1±1.7 years. All patients were divided into two groups: group 1 - patients with CKD and HD, group 2 - patients with newly diagnosed kidney damage against the background of coronavirus infection (COVID-19). Statistical data analysis was carried out using the software package "IBM SPSS Statistics 21.0" (USA) (Russified version).RESULTS. As a result of the study, it was found that in the clinical picture of COVID-19 patients suffering from CKD and undergoing hemodialysis, such a symptom as myalgia was noted 2 times more often, the percentage of saturation of arterial blood hemoglobin with oxygen (SaO2,%) was significantly lower compared to patients with newly diagnosed kidney damage on the background of infection. The duration of the temperature reaction during the disease was 5 times longer than in patients without CKD. Although the incidence of lung damage in patients of both groups was identical, mortality was significantly higher in the group of patients with CKD.CONCLUSION. In the patients examined by us, proteinuria, an increase in the level of nitrogenous metabolites, as well as D-dimers in both groups, are associated with increased mortality. Mortality in patients with CKD and HD was several times higher than in those without pathology of the urinary system. The severity of the patients' condition was primarily due to the symptoms of damage to the respiratory system, but the degree of renal dysfunction is undoubtedly an important prognostic value. Thus, monitoring the state of individual nephron structures in patients with CO-VID-19 is of great importance, and emergency nephroprotective measures may be crucial in the fight against cytokine storm.

Objective: To improve the diagnosis and treatment of acute cerebrovascular accident in patients with community-acquired pneumonia caused by the novel coronavirus infection (COVID-19). Materials and methods: For the first time, clinical manifestations of strokes in patients with diagnosed new coronavirus infection (COVID-19) were analyzed in 130 patients. The study was conducted in two groups. The main group consisted of 69,2 % (n = 90) with a clinical and instrumental diagnosis: novel coronavirus infection in combination with stroke. The control group (30,8 %; n = 40) included the cases of ischemic and hemorrhagic stroke without signs of SARS-CoV-2. In both groups, the severity of the disease and pathogenetic subtypes were compared, and the features of the laboratory biochemical data were studied. Statistical analysis of the outcomes was carried out taking into account the severity of brain and lung tissue damage. Results: In patients with cerebral stroke against the background of the new coronavirus infection (COVID-19), the prevalence of ischemic stroke cases (86,4 %) was noted for undetermined (41,4 %) and cardioembolic (35,7 %) pathogenetic subtypes (according to TOAST) with localization in the carotid basin (89,7 %). In hemorrhagic stroke, parenchymal hemorrhage was observed with a greater frequency (54,5 %). The severity of the diagnosed strokes according to the NIHSS scale was up to 13,16 (8,80) points with less severe brain damage — Glasgow coma scale (14,0 (12,0 15,0). In the group of the patients, a widespread lesion of the lung tissue was diagnosed in 82,2 % of cases. No significant increase in the incidence of clinically significant manifestations of systemic and organ hypercoagulation was established. Conclusions: In stroke patients with COVID-19, ischemic manifestations with undetermined and cardioembolic subtypes without age and gender features prevail, with no differences in the severity of the course and a large number of favorable outcomes. A high activity of inflammatory and infectious changes was established by clinical laboratory.

The study is devoted to the challenge of interpreting the lung damage associated with COVID-19 in children and the necessity for antimicrobial therapy in this disease. The aim of the research was a comparative analysis of clinical, radiological and laboratory signs in children with COVID-19 and community-acquired pneumonia (CAP). Methods. The observational comparative study included medical records of 53 children with the lung damage at the age of 1 year 4 months up to 17 years old, hospitalized for the period from June to August 2020. All children were tested for Severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) by polymerase chain reaction (PCR). 34 patients with SARS-CoV-2+ were diagnosed with COVID-19 and 19 children with SARS-CoV-2– were diagnosed with CAP. The assessment included medical history, clinical, laboratory and radiological changes. Results. Distinctive reliable clinical, laboratory, and X-ray signs of lung damage in COVID-19 compared to CAP were olfactory impairment (26%), bilateral lung damage (23%), erythrocytosis, leukopenia (20.6%), granulocyto- and monocytopenia, lower levels of reactive protein (CRP). Irrational prescribing of antibiotics (94%) was detected in the group of patients with COVID-19. Conclusion. We established the reliable clinical, laboratory and radiological features of COVID-19 in children, which indicate the viral nature of lung damage.

Abstract Background The clinical and imaging features of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections that progressed to coronavirus disease 2019 (COVID-19) have been explored in numerous studies. However, little is known about these features in patients who received negative respiratory nucleic acid test results after the infections resolved. In this study, we aim to describe these features in a group of Chinese patients. Methods This retrospective study includes 51 patients with mild-to-moderate COVID-19 (median age: 34.0 years and 47.1% male) between January 31 and February 28, 2020. Demographic, clinical, laboratory, and computed tomography (CT) imaging data were collected before and after two consecutive negative respiratory SARS-CoV-2 tests. Results Following a negative test result, the patients’ clinical symptoms continued to recover, but abnormal imaging findings were observed in all moderate cases. Specifically, 77.4% of patients with moderate COVID-19 exhibited multi-lobar lung involvement and lesions were more frequently observed in the lower lobes. The most common CT imaging manifestations were ground-glass opacities (51.6%) and fibrous stripes (54.8%%). Twelve of the 31 patients with moderate COVID-19 underwent repeated chest CT scans after a negative SARS-CoV-2 test. Among them, the ground-glass opacities decreased by > 60% within 1 week in seven patients (58.3%), but by < 5% in four patients (13.8%). Conclusions Following a positive and subsequent negative SARS-CoV-2 tests, patients with COVID-19 continued to recover despite exhibiting persistent clinical symptoms and abnormal imaging findings.

In 2020 the pandemic of a new coronavirus infection spread in almost all countries of the world. The danger of this infection lies in the damage to the lungs, which can lead to fatal outcomes. The success of treatment is largely determined by the early diagnosis of the disease and its timely treatment. In order to find the ways of early laboratory diagnosis of coronavirus infection, we studied changes in peripheral blood indicators, coagulograms and C-reactive protein in 56 outpatient patients with mild course of coronavirus infection, whose average age was 49±2 years (among them, 23.2% were men and 66.8% were women). In all patients, coronavirus infection was confirmed by the detection of SARS-CoV-2 RNA by polymerase chain reaction (PCR) in nasopharyngeal or oropharyngeal smears. Signs of lung damage were detected in 66% of patients according to computed tomography findings. The number of red blood cells and the level of hemoglobin in all patients were normal. In 7% of patients, thrombocytopenia was detected, in 5.3% of patients – thrombocytosis. The most pronounced changes are foundin the leucoformula and indicators of the blood coagulation system. In 12.5% of patients without signs of viral pneumonia, leukocytosis was detected. All cases of leukopenia were noted only against the background of lung damage, at this, in 16% lymphopenia was found, 43% had relative lymphocytosis. The coagulogram of more than half of the patients with pneumonia showed shortening of blood clotting in the activated partial thromboplastin time (APTT) test, an increase in prothrombin index(PI) and the content of fibrinogen. The level of C-reactive protein was increased in only a quarter of patients with mild lung damage. Thus, changes in the leucoformula against the background of a tendency to hypercoagulation in blood clotting indicators should cause doctors' apprehensive attitude when treating a patient with clinical symptoms similar to COVID-19.
