Features of the COVID-19 in lung tissue damage admitted to hospital

The COVID-19 pandemic continues to spread despite all the efforts of the medical community. The aim of the study - to identify the features of a new coronavirus infection (COVID-19) with lung tissue damage in men and women receiving inpatient treatment. Material and methods. The method of continuous sampling selected 225 patients admitted to inpatient treatment. The patients were divided in 2 groups: the 1st group - men (n=85), the 2nd group - women (n=140). Statistical processing was carried out using the IBM SPSS Statistics 22.0 program. Results. In a comprehensive study of the features of lung tissue damage by the new coronavirus infection SARS-CoV-2 in men and women was found that women received inpatient treatment more often, after ineffective outpatient treatment, the general serious condition at admission was more typical for women who had a positive result of a PCR-test for the detection of SARS-CoV-2 (p=0.038). In the presence of general clinical manifestations complaints of loss of sense of smell were more often presented by women (p=0.020). According to laboratory studies in the indicators of general clinical and biochemical blood tests, on average men often have higher levels of creatinine (p<0.001), women more often have elevated levels of ESR (p=0.003), erythrocytes (p<0.001), CRP (p=0.042) and decreased hemoglobin (p=0.029). Conclusion. In the first wave of the Wuhan pandemic of the SARS-CoV-2 virus strain women prevailed among patients admitted to inpatient treatment with lung tissue damage after ineffective outpatient treatment (p=0.038). There was a commonality in age and clinical manifestations, of the complaints in women, only loss of sense of smell was more common (p=0.020). The erythrocytosis detected in women, increased ESR and CRP, lower hemoglobin and creatinine levels are not specific for COVID-19. There were no statistically significant differences in the terms of hospitalization and the fatal outcome of the disease between men and women.Copyright © Eco-Vector, 2022.

Peripheral Blood Cellular Immunity Parameters in Covid-19

This article carried material about the results of the investigation of peripheral blood cellular immunity parameters in the COVID-19 patients with <= 30% lung damage hospitalizated in 2020 year. When infected with SARS-CoV-2 on the background of severe lymphopenia and neutrophilia were revealed the multidirectional changing in a cellular immunity parameters, the severity and dynamics of which can be determined by the initial type of immune system response.

Lung Injury in COVID-19 and Pneumocystis Pneumonia. Similarities and Differences

In the regions with the high prevalence of HIV infection, it is necessary to perform differential diagnosis of lung injury caused by COVID-19 and pneumocystis pneumonia. The main complaints in COVID-19 and pneumocystis pneumonia are similar and include dyspnea, weakness, cough, fever, and ground glass radiographic syndrome. However, sputum production was more common in pneumocystis pneumonia. The most important differences were frequent anosmia in COVID-19 and its absence in pneumocystis pneumonia, frequent detection of oropharyngeal candidiasis in pneumocystis pneumonia which was not seen in COVID-19. Serum hepcidin concentration has a high diagnostic potential and indicates a greater likelihood of COVID-19 than pneumocystis pneumonia at values ≤ 768.044 pg/ml (ROC AUC 0.977;p < 0.001). © 2022 New Terra Publishing House.

Comparative study of the serum hepcidin level of patients with pneumonia in COVID-19 and Pneumocystis pneumonia.

In the context of a pandemic caused by the SARS-CoV-2 virus, for a patient with respiratory symptoms and bilateral lung damage, COVID-19 becomes the first disease in the differential diagnostic search. Pneumonia in COVID-19 shares many characteristics with Pneumocystis pneumonia. One of the possible markers of the severe course of COVID-19 is hepcidin, a peptide hormone that negatively regulates iron metabolism. There are no data on the value of hepcidin in Pneumocystis pneumonia in the published scientific literature. The purpose of this study is to conduct a comparative analysis of hepcidin in the blood serum of patients with pneumonia in COVID-19 and Pneumocystis pneumonia to clarify their pathogenetic features. A case-control observational study was conducted, including 68 patients with pneumonia in COVID-19 and 44 patients with HIV infection and Pneumocystis pneumonia (PCP/HIV). Determination of hepcidin was carried out by ELISA using the ELISA Kit for Hepcidin. Statistical data processing was carried out using the MedCalc 19.2.6 software. Results. Comparative analysis of serum hepcidin levels in the study groups showed that hepcidin is statistically significantly higher in PCP/HIV than in COVID-19 - the median value is 22 times higher (p <0.0001). When examining the ROC curve for hepcidin, it was found that this biomarker has a high diagnostic potential and indicates a higher probability of COVID-19 than PCP/HIV at values ≤768.044 pg / ml. In the context of the COVID-19 pandemic, it is necessary to remember about other diseases that manifest themselves with a similar clinical and radiological picture. COVID-19 and PCP/HIV share many similarities; the peptide hormone hepcidin has shown itself as a potential differential diagnostic marker between them, and therefore the need for further studies of hepcidin is justified, taking into account the severity of the course of COVID-19, the presence of comorbidities and in a comparative aspect with pathologies that «mimic¼ under COVID-19.

Features of hematological and hemostasiological parameters in Coronavirus infection COVID-19 and community-acquired pneumonia

Against the background of priority attention paid to the COVID-19 pandemic, there are also cases of community-acquired pneumonia of a different genesis. Identification of the features of lung lesions in such diseases is relevant during the spread of seasonal respiratory infections. The comparative study of the dynamics of hematological and hemostasiological parameters of blood in patients with pneumonia of various origins is of interest in terms of searching for predictors of the prognosis of the diseases development. Aim. To compare the features of clinical symptoms, hematological and hemostasiological parameters in patients with pneumonia caused by COVID-19 and in patients with community-acquired pneumonia. Materials and methods. During cross-sectional study two groups were formed: group 1 consisted of 92 patients diagnosed with moderate community-acquired pneumonia caused by COVID-19 infection;group 2 included 40 patients diagnosed with moderate community-acquired bilateral polysegmental pneumonia. Results. It was found that patients with COVID-19 had an older age (69 vs 39.3 years), a lower body temperature at admission (37.5 vs 38.85 °C), a lower percentage of reduced oxygen saturation (less than 89 % in 5.4 % of cases vs 10 % of cases). In most cases, the average values of some hematological parameters in patients with COVID-19 did not go beyond the reference range. Leukopenia (below 4 × 109 cells/l) and lymphopenia (below 1.1 × 109 cells/l) were observed in 26 % and 38 % of cases respectively;thrombocytopenia (less than 100 × 109 cells/l) - in 12.2 % of cases;hyperfibrinogenemia (more than 4 g/l) - in 65.3 % of cases. A direct correlation was found between platelet levels and leukocytes (R = 0.53;p < 0.001) and lymphocytes (R = 0.29;p = 0.06). Compared with the patients of the group 2, on average, patients with COVID-19 had significantly lower levels of leukocytes and lymphocytes (2.5 times each;p < 0.001) and an increased level of fibrinogen (by 45 %;p < 0.001). Conclusion. In patients with pneumonia caused by COVID-19, we revealed the particular features of clinical symptoms, hematological and hemostasiological blood parameters compared to community-acquired nonspecific pneumonia. © 2021 Acta Biomedica Scientifica.

Hematological indicators for lung damage caused by COVID-19 infection.

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 infection¼.
