    Background: COVID-19 MESHD is a new infectious disease MESHD with severe disease course and high mortality in some groups. Blood tests on admission to the hospital can be useful for stratification of patients and timely correction. Our study investigated the clinical features of COVID-19 MESHD patients in Latvia and differences in blood tests in groups with different disease severity. Methods: The retrospective study included 100 patients hospitalized in Riga East Clinical University Hospital in Spring 2020. The severity of the disease course was classified by the presence of pneumonia MESHD and its combination with respiratory failure MESHD. We have assessed blood cells' count, hemoglobin, hematocrit, erythrocyte sedimentation rate (ESR), C-reactive protein HGNC ( CRP HGNC), alanine aminotransferase HGNC, lactate dehydrogenase (LDH), troponin T, electrolytes, creatinine, glomerular filtration rate (GFR), D-dimer, prothrombin time, prothrombin index, oxygen saturation, and temperature on admission to the hospital. Results: Patients were from 18 to 99, 57% males. Comorbidities were found in 74% of patients. The mild, moderate, and severe groups included 35, 44, and 16 patients, respectively. In the severe group, the mortality rate was 50%. The progression to severe COVID-19 MESHD was associated positively with temperature, ESR, CRP HGNC, creatinine, LDH, and troponin T and negatively associated with oxygen saturation, eosinophils, and GFR on admission to the hospital. Conclusions: COVID-19 MESHD severity associates with lower renal function and a higher level of inflammation MESHD and tissue damage. Eosinophils, CRP HGNC, ESR, LDH, troponin T, creatinine, and GFR are blood indicators for monitoring patients' condition.

    Background: Since December of 2019, novel coronavirus (SARS-CoV-2)-induced pneumonia MESHD ( COVID-19 MESHD) exploded in Wuhan, and rapidly spread throughout China. Patients with COVID-19 MESHD demonstrated quite different appearances and outcomes in clinical manifestations. We aimed to figure out whether risk factors of the cystatin C HGNC (CysC) and the CysC rangeability are influencing the prognosis of COVID-19 MESHD patients with or without type 2 diabetes mellitus MESHD ( T2DM MESHD).Methods: 675 T2DM MESHD patients and 602 non- T2DM MESHD patients were divided into low CysC group, high CysC group and low CysC rangeability group, high CysC rangeability group according to the serum CysC level and the change range of CysC. Demographic characteristics, clinical data and laboratory results of the four groups were collected and analyzed.Results: Our data showed that COVID-19 MESHD patients with high CysC level and CysC rangeability had more organic damage MESHD and higher mortality rate compared to those with low level or low rangeability of CysC. Furthermore, patients with higher CysC level and CysC rangeability also demonstrated higher blood lymphocytes (lymph), C-reactive protein HGNC (CRP), alanine aminotransferase HGNC (ALT), aspartate aminotransferase ( AST HGNC) which may greatly influence disease progression and poor prognosis of COVID-19 MESHD. After adjusting for possible confounders, multivariate analysis revealed that CysC≤0.93mg/dl as a reference, CysC>0.93mg/dl were significantly associated with the risk of heart failure MESHD (OR=2.401, 95% CI: 1.118–5.156) and all-cause death MESHD (OR=2.734, 95% CI: 1.098-6.811); referring to CysC rangeability≤0, CysC rangeability>0 significantly associated with all-cause death MESHD (OR=4.029, 95% CI: 1.864-8.706). Further grouped by T2DM MESHD, these associations were stronger in T2DM MESHD than in non- T2DM MESHD.Conclusions: It suggests that CysC level and CysC rangeability contribute to clinical manifestations and may influence the prognosis of COVID-19 MESHD. The CysC is considered as a potential risk factor of the prognosis of COVID-19 MESHD. Special medical care and appropriate intervention should be performed in COVID-19 MESHD patients with elevated CysC during hospitalization and later clinical follow-up, especially for those with T2DM MESHD.

    Background: Although CT characteristics of Coronavirus Disease 2019 MESHD ( COVID-19 MESHD) pneumonia MESHD between patients with mild and severe forms of the disease have already been reported in the literature, there was little attention to the correlation of imaging features and laboratory testing. We aimed to compare the laboratory and chest CT imaging features in patients with COVID-19 MESHD pneumonia MESHD between non-severe cases and severe cases, and to analyze the correlation of CT score and laboratory testing.Methods: This study consecutively included 54 patients with COVID-19 MESHD pneumonia MESHD (26 males and 28 females, 26 to 92 years of age, 43 cases with non-severe and 11 cases with severe group). Clinical, laboratory and image data were collected between two subgroups. A CT score system was used to evaluate the extent of disease. Correlation between the CT score and laboratory data were estimated. Receiver operating characteristic (ROC) analysis was used to evaluate the diagnostic performance of CT score and laboratory tests.Results: Compared with non-severe patients, severe patients had showed increased white blood cell count, neutrophil count, neutrophil percentage, the neutrophil-to-lymphocyte ratio (NLR) and decreased lymphocyte percentage (all p < 0.05). Architectural distortion, pleural effusion MESHD, air bronchogram and consolidation-dominant pattern were more common in the severe group (all p < 0.05). CT score of the severe group was higher than the non-severe group (p < 0.001). For distribution characters of the lesions, diffuse pattern in the transverse distribution was more often seen in the severe group (p < 0.001). CT score was positively correlated with the white blood cell counts, neutrophil counts, the percent of neutrophil, NLR, alanine aminotransferase HGNC, lactate dehydrogenase and C-reactive protein HGNC, and was inversely related to the lymphocyte, the percent of lymphocyte. ROC analysis showed that when the optimal threshold of CT score was 13, the area under the curve was the largest, which was 0.855, and the sensitivity and specificity were 100% and 60% respectively for the diagnosis of the severe patients.Conclusion: CT score showed significant correlations with laboratory inflammatory markers, suggesting that chest CT and laboratory examination maybe provide a better reference for clinicians to judge the severity of diseases.

    Background The ongoing epidemics of coronavirus disease 2019 MESHD ( COVID-19 MESHD) have caused serious concerns about its potential adverse effects on pregnancy. There are limited data on maternal and neonatal outcomes of pregnant women with COVID-19 MESHD pneumonia MESHD. Methods We conducted a case-control study to compare clinical characteristics, maternal and neonatal outcomes of pregnant women with and without COVID-19 MESHD pneumonia MESHD. Results During January 24 to February 29, 2020, there were sixteen pregnant women with confirmed COVID-19 MESHD pneumonia MESHD and eighteen suspected cases who were admitted to labor in the third trimester. Two had vaginal delivery and the rest took cesarean section. Few patients presented respiratory symptoms ( fever MESHD and cough MESHD) on admission, but most had typical chest CT images of COVID-19 MESHD pneumonia MESHD. Compared to the controls, COVID-19 MESHD pneumonia MESHD patients had lower counts of white blood cells (WBC), neutrophils, C-reactive protein HGNC ( CRP HGNC), and alanine aminotransferase HGNC (ALT) on admission. Increased levels of WBC, neutrophils, eosinophils, and CRP HGNC were found in postpartum blood tests of pneumonia MESHD patients. There were three (18.8%) and two (10.5%) of the mothers with confirmed or suspected COVID-19 MESHD pneumonia MESHD had preterm delivery due to maternal complications, which were significantly higher than the control group. None experienced respiratory failure MESHD during hospital stay. COVID-19 MESHD infection was not found in the newborns and none developed severe neonatal complications. Conclusion Severe maternal and neonatal complications were not observed in pregnant women with COVID-19 MESHD pneumonia MESHD who had vaginal delivery or caesarean section. Mild respiratory symptoms of pregnant women with COVID-19 MESHD pneumonia MESHD highlight the need of effective screening on admission.

    Background Since late December, 2019, an outbreak of pneumonia MESHD cases caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in Wuhan, and continued to spread throughout China and across the globe. To date, few data on immunologic features of Coronavirus Disease 2019 MESHD ( COVID-19 MESHD) have been reported. Methods In this single-centre retrospective study, a total of 21 patients with pneumonia MESHD who were laboratory-confirmed to be infected with SARS-CoV-2 in Wuhan Tongji hospital were included from Dec 19, 2019 to Jan 27, 2020. The immunologic characteristics as well as their clinical, laboratory, radiological features were compared between 11 severe cases and 10 moderate cases. Results Of the 21 patients with COVID-19 MESHD, only 4 (19%) had a history of exposure to the Huanan seafood market. 7 (33.3%) patients had underlying conditions. The average age of severe and moderate cases was 63.9 and 51.4 years, 10 (90.9%) severe cases and 7 (70.0%) moderate cases were male. Common clinical manifestations including fever MESHD (100%, 100%), cough (70%, 90%), fatigue MESHD (100%, 70%) and myalgia MESHD (50%, 30%) in severe cases and moderate cases. PaO2/FiO2 ratio was significantly lower in severe cases (122.9) than moderate cases (366.2). Lymphocyte counts were significantly lower in severe cases (7000 million/L) than moderate cases (11000 million/L). Alanine aminotransferase HGNC, lactate dehydrogenase levels, high-sensitivity C-reactive protein HGNC and ferritin were significantly higher in severe cases (41.4 U/L, 567.2 U/L, 135.2 mg/L and 1734.4 ug/L) than moderate cases (17.6 U/L, 234.4 U/L, 51.4 mg/L and 880.2 ug /L). IL-2R HGNC, TNF HGNC- and IL-10 HGNC concentrations on admission were significantly higher in severe cases (1202.4 pg/mL, 10.9 pg/mL and 10.9 pg/mL) than moderate cases (441.7 pg/mL, 7.5 pg/mL and 6.6 pg/mL). Absolute number of total T lymphocytes, CD4+T cells and CD8+T cells decreased in nearly all the patients, and were significantly lower in severe cases (332.5, 185.6 and 124.3 million/L) than moderate cases (676.5, 359.2 and 272.0 million/L). The expressions of IFN-{gamma HGNC} by CD4+T cells tended to be lower in severe cases (14.6%) than moderate cases (23.6%). Conclusion The SARS-CoV-2 infection MESHD may affect primarily T lymphocytes, particularly CD4+T cells, resulting in significant decrease in number as well as IFN-{gamma HGNC} production, which may be associated with disease severity. Together with clinical characteristics, early immunologic indicators including diminished T lymphocytes and elevated cytokines may serve as potential markers for prognosis in COVID-19 MESHD.
