The purpose of the study. To identify the main CT signs of colon inflammatory in patients with COVID-19, to correlate the detected signs with clinical manifestations and therapy, as well as to assess the validity of prescribing antibacterial therapy in accordance with Temporary guidelines for the treatment of coronavirus infection.Materials and methods. The data of CT scans of the chest and medical records were analyzed in 30 patients with confirmed coronavirus infection, in whom changes in the colon wall appeared in dynamics at the scanning level during CT. Laboratory data indicators, prescribed therapy, the presence of combined diseases were evaluated.Results. According to CT data, in dynamics in all patients – circular thickening of the colon wall with loss of gaustration, thickening of the submucosal layer in 63,3%, in 93,3% – edema of paracolic fiber. Shifts in the laboratory parameters were noted at admission: leukocytosis in 16.6%, an increase in procalcitonin in 13,3%; leukocyturia, bacteriuria – in 20%. None of the patients had indications of abdominal symptoms at admission, in dynamics at least one abdominal/dyspeptic symptom appeared in 76,6%. Fecal analysis for C.difficile toxins was taken in 50% patients, in 60% the result is positive. All patients were prescribed antibiotics and other therapy in the first 1–3 days of hospitalization. In 53,3%, levofloxacin (per os) was prescribed in combination with protected generation III cephalosporin (intravenously).Conclusions. Shifts in colon with C.difficile colitis in patients with COVID-19 according to CT data are highly likely to reflect the appearance of a pathological process and necessarily require a conclusion. There was a fact of irrational prescription of antibacterial therapy. Clear criteria for prescribing antibiotics against the background of immunosuppressive therapy are needed.

Abstract In order to identify the clinical characteristics of patients with Corona Virus Disease 2019 (COVID-19) and find out the characteristic effects of 2019 New Coronavirus (SARS-CoV-2) infection on changes in clinical and laboratory data, we analyzed the medical records of 80 suspected cases who admitted in the national designated hospital due to the relevant clinical manifestations of SARS-CoV-2 infection from January 22 to February 13, 2020. 62 (77.5%) confirmed cases and 18 (22.5%) negative cases were confirmed by SARS-CoV-2 nucleic acid test. Epidemiological investigation and statistical analysis were carried out on the clinical and laboratory data of all suspected cases of COVID-19, the specific indicators were found, and the clinical characteristics of COVID-19 were described. Compared with the patients with negative nucleic acid test, the patients with positive nucleic acid test showed shorter time of onset of symptoms, higher plasma CO2 level, lower eosinophil ratio, lower platelet count and hematocrit, lower serum sodium level, higher serum creatinine, higher blood urea and plasma albumin levels (all P<0.05). Our results might provide some suggestions in diagnosis, clinical treatment and prevention for COVID-19.

During the pandemic of a new coronavirus infection one of the most serious complications is pneumonia. When entering a specialized pulmonology Department, the presence of pneumonia is confirmed by computed tomography (CT), the etiology is confirmed by the detection of SARS-CoV-2 RNA by PCR, the article analyzes the indicators of blood analysis when patients are admitted to the hospital. All admitted patients were divided into 2 groups. Group 1 of the study - with a new coronavirus infection Covid-19, confirmed by the detection of PCR-RNA SARS-CoV-2 (n=27). Group 2 consisted of 65 patients (70.7%) with lung tissue damage characteristic of Covid-19 according to CT, who had a negative analysis of PCR-RNA SARS-CoV-2. Statistically significant deviations were shown in a decrease in the percentage and absolute content of lymphocytes, monocytes and platelets, and an increase in neutrophils. The comparative analysis in the groups with positive and negative PCR analysis for the detection of SARS-CoV-2 RNA showed no statistically significant differences. It can be assumed that with the similarity of clinical manifestations and CT-data, a negative result of PCR-RNA SARS-CoV-2 can be diagnosed as «lung damage caused by COVID-19 infection».

Inflammatory Changes

A study was conducted to determine the possibility of using and evaluate the effectiveness of nuclear medicine methods for diagnosing inflammatory changes in the cardiovascular system in patients with coronavirus infection. The study ex-amined 10 patients with a confirmed moderate-severity COVID-19 infection without a history of cardiovascular dis-eases. The diagnosis was performed using PET / CT with 18-FDG. In the future, a visual assessment of the degree of accu-mulation of radiopharmaceuticals drugs in the myocardium and its distribution. For comparison, we used PET / CT data of the myocardium of healthy patients from the Department's database. According to the results of the study, 25% showed an increased accumulation of radiopharmaceutical in the myocardium without a clear correspondence to the vascular highways, which indicates the presence of an inflammatory process in the heart muscle, despite the absence of clinical manifestations. The study shows the high efficiency of molec-ular imaging methods in the diagnosis of inflammatory changes in the cardiovascular system in patients with COVID-19.

The article analyzes the mechanisms of the development and clinical manifestations of multi-organ dysfunction and multi-organ failure syndrome, which often accompany the severe COVID-19. Moreover, since multiple organ dysfunction during severe COVID-19 may be caused by a cytokine storm resulting from elevated inflammatory mediators, endothelial dysfunction, coagulation disorders, and inflammatory cell infiltration, further studies are needed to determine the exact mechanisms of pathogenesis. Since the involvement of multiple organs in the pathological process of the disease during coronavirus infection is an important and complex medical, mental, tactical, physical, emotional, and economic task for both clinicians and patients and their families, increasing knowledge of the pathological process can help improve outcomes and reduce morbidity and mortality. The review includes some results of our own experience in the treatment of severe cases of coronavirus disease.

Lymphadenopathy is enlarged lymph nodes caused by infection, inflammation or malignancy. On HIV positive patients, lymphadenopathy is one of the most common clinical manifestations and it is usually persistent. Fine-needle aspiration biopsy (FNAB) is an effective cytology technique in determining the diagnosis of lymphadenopathy. This study aimed to describe the cytopathology of lymphadenopathy in HIV positive patients. This is a descriptive study of 21 cases of lymphadenopathy in patients with HIV positive who underwent FNAB examination in Anatomical Pathology Department of Dr.Hasan Sadikin Hospital between 2013-2014. Medical data was taken from the patient medical records including age, sex, location, size and cytopathological diagnosis. Cytopathology overview of FNAB specimens were reassessed by 2 pathologists. In this study, lymphadenopathy in HIV positive patients were mainly found in men (n = 15.71%) with an average age between 20-30 years. The most frequent location was the neck (n = 20.95.2%). The lymph nodes size were found between 0.5-3 cm. Most diagnosis was tuberculous lymphadenitis (n = 15.71%) with the most common cytology feature was granulomatous lymphadenitis (n = 5.33.3%) and suppurative lymphadenitis (n = 5.33.3%). FNAB examination in lymphadenopathy is very helpful to identify the cause of infection in HIV positive patients. Keywords: FNAB, HIV, lymphadenopathy, cytopathology

The present article addresses the definition of cerebral amyloid angiopathy (CAA) and its symptoms based on the analysis of the medical case; the issues of diagnosis and treatment of this pathology are discussed. The Boston criteria, which became the basis for diagnosis, study of clinical manifestations and progression of CAA and approaches to its therapy, are presented. Methods and modes of neuroimaging, including magnetic resonance imaging (MRI), which verify micro cerebral haemorrhage, are described. At the same time, the role and significance of cardiac arrhythmias in the genesis of ischemic stroke are discussed, and scales for assessing the risk of its occurrence are presented. The observation of the neurological, somatic, neuroimaging, neuropsychological status of a 62-year-old patient confirms quite rare combination of probable CAA, paroxysmal atrial fibrillation and repeated hemorrhagic functional apoplexy (FA). The relevance of the case described, is a complex clinical dilemma based on mutually exclusive recommendations for the pharmacological correction of such conditions. It is emphasized that in many multicenter clinical studies on the effectiveness of antithrombotic medication (antiaggregants, anticoagulants) in the treatment and prevention of ischaemic functional apoplexy , an important exclusion criterion is a hemorrhagic stroke in past history (including the multiple changes in haemostasis indicators). Taking into account the obtained clinical and laboratory data in the dynamics, the tactics of treating the described patient were determined. The results of studies related to the treatment of comorbid pathology that should become the subject of the development of a personalized algorithm for managing patients in each specific case, are discussed.

AbstractMultiple myeloma (MM) is an immunoglobulin-producing tumor of plasma cells, which occurs commonly in the elderly. The incidence of myocardial amyloidosis with MM is extremely low and early clinical manifestations are nonspecific. The diversity of clinical manifestations and first episode symptoms often cause misdiagnosis in young patients with myocardial amyloidosis following MM. In this study, we analyzed the clinical data of a young woman with MM and impaired cardiac function combined with echocardiography, electrocardiography (ECG), laboratory data, cell Congo Red staining, and other manifestations to diagnose amyloidosis. Considering the rapid progression, short survival, and poor prognosis in most patients, a clear, definitive, and timely diagnosis is essential for the treatment of patients with MM complicated with myocardial amyloidosis.

Abstract Background Autoimmune encephalitis (AE) is now considered a main, potentially curable cause of encephalitis, but remains conspicuously underreported from South Asia. We studied the clinical characteristics in relation to their antibody status and outcomes of patients presenting with AE in Sri Lanka. Methods Patients admitting to government hospitals who were clinically suspected of AE by an on-site neurologist were prospectively recruited over a period of 12 months. Sera and cerebrospinal fluid were tested for NMDAR, AMPAR1, AMPAR2, LGI1, CASPR2, GABARB1/B2 antibodies (Ab) using commercial cell-based assays. Demographic, clinical and laboratory data were compiled into an investigator-administered proforma. Patients were reviewed at 1 year follow up either in person or via telephone. Results One-hundred and forty-two patients from 21 of 25 districts in Sri Lanka (median age = 20.5 years; range 1–86 years; females = 61.3%) were recruited. Of them, 65 (45.8%; median age = 19 years; range 1–86 years; females = 64.6%) fulfilled diagnostic criteria for probable NMDAR-antibody encephalitis (NMDARE) and 6 (4.2%; median age = 44 years; range 28–71 years; females = 83.3%) limbic encephalitis (LE). Abnormal behaviour (95.3%), seizures (81.5%) and movement disorders (69.2%) were the most frequent clinical manifestations of probable NMDARE. NMDAR-antibodies were detectable in 29 (44.6%) and not detectable in 36 in CSF of probable-NMDARE patients. Abnormal EEG was more frequent (p = 0.003) while a worse outcome (OR = 2.78; 95% CI = 0.88–9.09) and deaths (OR = 2.38; 95% CI = 0.67–8.33) were more likely in antibody-negative than antibody-positive probable-NMDARE. Most patients with LE had amnesia (50%) and/or confusion (100%) with agitation (83.3%) and seizures (100%) but none had detectable antibodies to any of the antigens tested. Conclusions NMDARE is the commonest type of AE among South Asians as is the case worldwide. Clinical presentations of NMDARAb-positive and NMDARAb-negative AE patients do not significantly differ but EEG may be a useful marker of an autoimmune basis for psychiatric symptoms.

The Mean

Background:Currently it is hypothesized that many systemic autoimmune diseases occur due to environmental risk factors in addition to genetic risk factors. Anti-Neutrophil Cytoplasmic Antibody (ANCA) is mainly associated with three systemic autoimmune disease including granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (EGPA). It is known that ANCA can be positive before clinical symptoms in patients with known diagnosis of GPA and ANCA titers rise before clinical manifestations appear. However, prevalence of ANCA among general population is not well known. It has not been described as well how many of people with positive ANCA eventually develop clinical manifestations of ANCA associated Vasculitis.Objectives:This study aims to estimate prevalence of ANCA in general population without ANCA associated Vasculitis. It also describes natural disease course of people with positive ANCA without ANCA associated Vasculitis. Risk factors for positive ANCA are also analyzed.Methods:This is a single center retrospective study at Center for Preventive Medicine of St. Luke’s International Hospital in Tokyo. ANCA was checked among the patients who wished to between 2018 and 2019. St. Luke’s Health Check-up Database (SLHCD) was utilized to collect the data. The patients whose serum was measured for ANCA were identified. The data for basic demographics, social habits, dietary habits and laboratory data were extracted. The charts of the patients with positive ANCA were reviewed.Results:Sera of total 1204 people were checked for ANCA. Of these 1204 people, 587 (48.8%) are male and the mean age was 55.8 years (32.6 to 79). There were total 11 patients with positive ANCA. Myeloperoxidase ANCA (MPO-ANCA) was positive for 3 patients and proteinase 3 ANCA (PR3-ANCA) was positive for 8 patients. Of these 11 patients, 5 were male (45.5%) and the mean age was 54.6 years. Two patients had history of autoimmune disease (primary biliary cirrhosis and ulcerative colitis). Five patients were evaluated by rheumatologists with the median follow-up period of 274 days. None of them developed clinical signs and symptoms of ANCA associated Vasculitis. Four out of five patients had ANCA checked later, two of which turned negative. The prevalence of ANCA in this cohort was 0.9% (95% confidence interval [95% CI]: 0.5% to 1.6%). Univariate analysis was performed to identify risk factors of positive ANCA. The variables analyzed include age, gender, body mass index (BMI), smoking habits, alcohol intake, dietary habits (fruits, fish, red meat), hypertension, dyslipidemia, and laboratory data. None of these variables demonstrated statistically significant differences except for positive rheumatoid factor (ANCA positive group: 33 % vs ANCA negative group: 9.1%, p value = 0.044).Conclusion:The prevalence of ANCA in this cohort was 0.9% (95% CI: 0.5% to 1.6%). None of them who had a follow-up developed ANCA associated Vasculitis during the follow-up period. Longer follow-up and more patients are necessary to determine natural course of people with positive ANCA.Disclosure of Interests:None declared
