    Background:As everyone knows, the pandemic COVID-19 is spreading in the whole world. The number of laboratory- confirmed cases TRANS reached 28,637,211 and that of the death cases was 917,404 in the world as of September 13th, 2020. We sought to analyse the clinical characteristics, laboratory findings and therapy of some cases with COVID-19.Methods: In this retrospective study, we extracted the data on 134 patients with laboratory-confirmed COVID-19 in Wuhan Xinzhou District People's Hospital from January 16th to April 24th , 2020. Cases were confirmed TRANS by real-time RT-PCR and abnormal radiologic findings. Outcomes were followed up until May 1th , 2020. Results: Co-infection MESHD infection and severe HP underlying diseases made it easier for a case with COVID-19 to develop to be a severe one or reach an outcome of death MESHD. Age TRANS above 60 years old, male TRANS and symptoms such as fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, headaches HP headaches MESHD and fatigue HP fatigue MESHD were related to severe COVID-19 and an outcome of death MESHD. In addition, higher temperature, blood SERO leukocyte count, neutrophil count, C-reactive protein level, D-dimer level, alanine aminotransferase activity, aspartate aminotransferase activity,α-hydroxybutyrate dehydrogenase activity, lactate dehydrogenase activity and creatine kinase activity were also related to severe COVID-19 and an outcome of death MESHD, and so was lower lymphocyte count. Administration of gamma globulin seemed helpful for reducing the mortality of patients with severe COVID-19, however the P value was greater than 0.05 (P=0.180), which mean under the same condition, studies of larger samples are needed in the future.                 Conclusion: Multiple factors were related to severe COVID-19 and an outcome of death MESHD.  Administration of gamma globulin seemed helpful for reducing the mortality of severe cases. More related studies are needed in the future.

    Background: Coronavirus 2019 (COVID-19) is a novel infectious disease MESHD that was first reported in Wuhan, China, but has spread to all parts of the world. At the same time, because China has millions of HBV carriers TRANS, HBV infection MESHD has become a major public health problem in China. In this study, we aim to describe the clinical features of HBV carriers TRANS (AsC) infected with COVID-19 and to assess the factors that may affect the outcome during disease progression.Methods: This retrospective cohort study included 72 patients diagnosed with COVID-19 in Wuhan Jinyintan Hospital. These patients were also diagnosed as HBV carriers TRANS. The epidemiological characteristics, demographic features, clinical manifestations, laboratory test, treatment, management and final outcome were collected and analyzed.Results: The median age TRANS of 72 patients is 58.5 years old, of which 55.56% (n=40) are male TRANS. 20 (30.56%) patients were severe cases and 50 (69.44%) were non-severe cases. Fever HP Fever MESHD is the most common symptom, followed by cough HP, chest tightness HP chest tightness MESHD and sputum. Laboratory test results including hematologic, biochemical, infection MESHD and coagulation parameters and several indicators, such as Aspartate Aminotransferase (AST), Total Bilirubin (TBil), Direct Bilirubin (DBil), Indirect Bilirubin (IBil), γ-glutamyl Transferase (GGT) showed difference between their admission and discharge. The level of Prealbumin (PA) and Serum SERO Amyloid A (SAA) in the study showed a significant trend from high to low, which has statistical significance.Conclusions: The clinical features of HBV carriers TRANS with COVID-19 have obvious systemic symptoms, such as fever HP fever MESHD, cough HP cough MESHD, and chest tightness HP chest tightness MESHD. Compared with liver function data on admission and discharge, SARS-CoV-2 does not directly activate the Hepatitis HP Hepatitis MESHD B virus, and the risk of liver cell damage of HBV carriers TRANS with COVID-19 does not increase. Both PA and SAA are sensitive indicators and can be used to evaluate the prognosis and outcome of these patients.

    Background: A new pathogenic disease named COVID-19 became a global threat, first reported in Wuhan, China, in December 2019. The number of affected cases growing exponentially and now, more than 210 countries confirmed the cases TRANS. Objective: This meta-analysis aims to evaluate risk factors, the prevalence SERO of comorbidity, and clinical characteristics in COVID-19 death MESHD patients compared to survival patients that can be used as a reference for further research and clinical decisions. Methods: PubMed, Science Direct, SAGE were searched to collect data about demographic, clinical characteristics, and comorbidities of confirmed COVID-19 patients from January 1, 2020, to May 17, 2020. Meta-analysis was performed with the use of Review Manager 5.3 Results: Eighty-five studies were included in Meta-analysis, including a total number of 67,299 patients with SARS-CoV-2 infection MESHD. Males TRANS are severely affected or died than females TRANS (OR = 2.26, p < 0.00001; OR = 3.59, p < 0.00001) are severely affected, or died by COVID-19 and cases with age TRANS [≥]50 are at higher risk of death MESHD than age TRANS <50 years (OR=334.23). Presence of any comorbidity or comorbidities like hypertension HP hypertension MESHD, cardiovascular disease MESHD, diabetes MESHD, cerebrovascular disease MESHD, respiratory disease MESHD, kidney disease MESHD, liver disease MESHD, malignancy MESHD significantly increased the risk of death compared to survival (OR = 3.46, 3.16, 4.67, 2.45, 5.84, 2.68, 5.62, 2.81,2.16). Among the clinical characteristics such as fever HP fever MESHD, cough HP cough MESHD, myalgia HP myalgia MESHD, diarrhea HP diarrhea MESHD, abdominal pain HP abdominal pain MESHD, dyspnea HP dyspnea MESHD, fatigue HP fatigue MESHD, sputum production, chest tightness HP chest tightness MESHD headache HP and nausea or vomiting HP nausea or vomiting MESHD, only fatigue HP fatigue MESHD (OR = 1.31, 95%) and dyspnea HP dyspnea MESHD increased the death significantly (OR= 1.31, 4.57). The rate of death of COVID-19 cases is 0.03-times lower than the rate of survival (OR = 0.03). Conclusion Our result indicates that male TRANS patients are affected severely or died, the rate of death is more in the age TRANS [≥]50 group, and the rate of death is affected by comorbidities and clinical symptoms.

    Background: Information regarding the impact of cardiovascular disease MESHD ( CVD MESHD) on disease progression among patients with mild coronavirus disease MESHD 2019 (COVID-19) is limited. Methods: This study evaluated the association of underlying CVD MESHD with disease progression in patients with mild COVID-19. The primary outcome was the need to be transferred to intensive care due to disease progression. The patients were divided with and without CVD MESHD as well as stable and intensive care groups. Results: Of 332 patients with mild COVID-19, median age TRANS was 51 years (IQR, 40-59 years), and 200 (61.2%) were female TRANS. Of 48 (14.5%) patients with CVD MESHD, 23 (47.9%) progressed to severe disease status and required intensive care. Compared with patients without CVD MESHD, patients with CVD MESHD were older, and more likely to have fatigue HP fatigue MESHD, chest tightness HP chest tightness MESHD, and myalgia HP myalgia MESHD. The rate of requiring intensive care was significantly higher among patients with CVD MESHD than in patients without CVD MESHD (47.92% vs. 12.4%; P<0.001). In subgroup analysis, rate of requiring intensive care was also higher among patients with either hypertension HP hypertension MESHD or coronary heart disease MESHD than in patients without hypertension HP hypertension MESHD or coronary heart disease MESHD. The multivariable regression model showed CVD MESHD served as an independent risk factor for intensive care (Odd ratio [OR], 2.652 [95% CI, 1.019-6.899]) after adjustment for various cofounders. Conclusions: Patients with mild COVID-19 complicating CVD MESHD in are susceptible to develop severe disease status and requirement for intensive care.

    Background: Since December 2019, a severe novel coronavirus ( SARS-CoV-2) infection (Coronavirus Disease MESHD 2019,COVID-19) has occurred in Wuhan, China, and has rapidly spread to the country and around the world. This study intends to investigate the epidemiological and clinical characteristics of patients with COVID-19 in a surrounding city of Wuhan.Methods: A retrospective study was conducted on 208 cases of COVID -19 patients from February 11, 2020 to February 29, 2020 in Xiaogan dongnan Hospital, collected basic information, history of exposure, medical history, clinical symptoms, laboratory indicators and pulmonary imaging Data, and analyzed the epidemiological and clinical characteristics of all patients. According to the clinical classification criteria, 208 patients were divided into light group and ordinary group, and the epidemiological and clinical characteristics of the two groups were compared.Results: Among 208 patients in this study, with a median age TRANS of 50.5 years (IQR,36-64.7,range,10-91 years), among which 107 (51.4%) were males TRANS and 101 (48.6%) were females TRANS. 51 (24.5%) had a clear exposure to COVID-19 infection within 2 weeks before admission, and 40 (19.2%) had a history of residence or exposure in Wuhan within 2 weeks before admission. Among all the patients, there were 16 (7.7%) with pulmonary diseases MESHD, 41 (19.7%) with hypertension HP hypertension MESHD, 11 (5.3%) with coronary heart disease MESHD, 13 (6.3%) with diabetes MESHD, 12(5.8%) with a history of alcohol consumption, and 12(5.8%) with a history of smoking. Among all clinical symptoms, 146 cases (70.2%) of fever HP fever MESHD, the highest temperature range was 37.3℃-41℃ before admission, 115 (55.3%) cases of cough HP, and 57 (27.4%) cases of chest tightness HP chest tightness MESHD, 47 (22.6%) cases of fatigue HP fatigue MESHD, 28 (13.5%) cases of inappetence, 9 (4.3%) cases of diarrhea HP diarrhea MESHD, 7 (3.4%) cases of nasal congestion or runny nose , and 5 ( 2.4%) cases of pharyngalgia. Analysis of the laboratory results of 208 patients showed that 42 (20.2%) cases had decreased white blood SERO cell count, and 61 (29.3%) cases had decreased lymphocyte count. There were 154 (74%) cases with elevated CRP, 50 (24%) cases with elevated fasting blood SERO glucose, and 23 (11.1%) cases with elevated LDH (>245U/L). The comparison of clinical characteristics between the light group and the common group showed that the median age TRANS of the light group was 44.8 years (IQR 30-58), the median age TRANS of the common group was 53.1 years (IQR 38.8-67) (P<0.01). The symptoms of fever HP fever MESHD [53(80.3%) vs 93(65.5%),P<0.05], fatigue HP fatigue MESHD [53(80.3%) vs 93(65.5%),P<0.05] and inappetence [4(6.1%) vs 24(16.9%),P<0.05] in the light group were less than those in the common group. The white blood SERO cell count (5.48 vs 6.37, P<0.05), lymphocyte count (1.40 vs 1.61, P<0.05) and HDL-C (1.5 vs 1.3, P<0.05) of the common group were lower than that of the light group, while CRP (26.5 vs 22.1, P<0.01), AST (22.9 vs 18.5, P<0.05), fasting blood SERO glucose (5.8 vs 5.6, P<0.05), LDH (196.8 vs 157.9, P<0.001) of the common group were higher than that of the light group.Conclusion: COVID-19 infection is mainly in middle- aged TRANS and elderly TRANS patients, patients with other diseases MESHD are more susceptible to infection. The main symptoms of COVID-19 infection MESHD were fever HP fever MESHD, cough HP cough MESHD, chest tightness HP chest tightness MESHD, fatigue HP fatigue MESHD, and inappetence. Decreased lymphocyte count, increased CRP concentration, increased LDH concentration and decreased HDL-C concentration were the laboratory features of COVID-19 infection MESHD, and were important indicators to assess the severity of COVID-19 disease.

    Objective: To explore relevant risk factors for severity of patients with novel coronavirus pneumonia MESHD pneumonia HP (COVID-19).Methods: The clinical data of 292 patients with COVID-19 admitted to Hubei Provincial Hospital of Integrated Chinese & Western Medicine from January 1, 2020 to February 29, 2020 were analyzed retrospectively. Patients were divided into mild or severe group according to the Guidance for Corona Virus Disease MESHD 2019 (7th version) released by the Chinese National Health Committee. The clinical data were collected at the time of admission, including demographics, clinicalcharacteristics, laboratory test results, imaging characteristics and outcome of treatment. We applied univariable and multivariable logistic regression methods to explore the risk factorsassociated with severity of the disease.Results: The median age TRANS of patients in the severe group((68.19 ± 12.51)years) was significantly older than mild group((54.14 ± 13.62)years). The male TRANS sex was more predominant in severe group (63.45%) than that of mild group (38.1%). There were more smokers (8.97% vs 1.36%) and drinkers (4.14% vs 0%) in severe group than that of mild group. Patients in the severe group had more underlying diseases. Hypertension HP Hypertension MESHD(48.97% vs 23.81%), coronary heart disease MESHD (22.07% vs 1.36%, P < 0.0001), chronic obstructive pulmonary disease HP chronic obstructive pulmonary disease MESHD (6.21% vs 1.36%), malignant tumor MESHD (7.59% vs 2.04%) and chronic kidney disease HP chronic kidney disease MESHD (3.45% vs 0%) were more frequent in severe group than in mild group.The dyspnea HP dyspnea MESHD, chest tightness HP chest tightness MESHD and dry cough MESHD cough HP were more common in severe group (43.45%, 66.9% and 66.21%) than in mild group (23.13%, 44.22% and 53.74%). Abnormality of chest radiography were more frequent in the severe group, there were more ground glass opacities, consolidation of lung and white lung in the severe cases (88.97%, 44.07% and 46.21%) than in mild cases (78.91%, 19.05% and 2.04%). Patients in the severe group were more likely to receive methylprednisolone, oxygen therapy and mechanical ventilation. Lasso algorithm showed that age TRANS, C-reactive protein (CRP), creatine kinase (CK) and α-hydroxybutyrate dehydrogenase (α-HBDB) were the independent risk factors for severeCOVID-19, and CD4+T lymphocyte count was the protective factor.Conclusion: This large-scale retrospective study of 292 COVID-19 patients revealed that age TRANS, CRP, CK,α-HBDB and CD4+T lymphocyte were independent risk factors for severity of COVID-19. Identifying patients with risk factors at an early stage of the disease are helpful for outcome prediction and clinical management.
