    Introduction/objectives: An interleukin-6 inhibition strategy could be effective in selected COVID-19 patients. The objective is to present our experience of tocilizumab use in patients with severe COVID-19. Methods: Observational retrospective cohort study. Hospitalized patients were evaluated by our multidisciplinary team for eventual use of tocilizumab. Patients with progressive ventilatory impairment MESHD and evidence of a hyperinflammatory state despite usual treatment received tocilizumab 8 mg/kg intravenous (maximum dose 800 mg), in addition to standard treatment. The use and time of use of mechanical ventilation (MV), the change of the Alveolar-arterial MESHD ( A-a MESHD) gradient, of the ratio of arterial oxygen partial pressure to fractional inspired oxygen (PaO2/FiO2) and of inflammation MESHD laboratory parameters after 72 hours of tocilizumab use was evaluated. Results: 29 patients received tocilizumab. 93.1% were men, 37.9% were obese MESHD, and 34.5% had hypertension HP hypertension MESHD. Of the 20 patients who were not on MV when receiving tocilizumab, 11 required non-invasive MV, for an average of five days, and one of them required intubation. A-a MESHD gradient, PaO2/FiO2, and inflammation MESHD parameters improved significantly. A better lymphocyte count, which improved significantly after tocilizumab use, was significantly associated with less use of MV. Five patients presented positive culture samples after tocilizumab, three being of clinical significance. A lower lymphocyte count was associated with having a positive culture. No other significant adverse events were seen. Conclusion: Our study suggests the utility and shows the safety of tocilizumab use in COVID-19 patients who have respiratory failure HP respiratory failure MESHD and evidence of hyperinflammation. Lymphocyte improvement was a predictor of good response.

    Objectives To characterise the clinical features of hospitalised COVID 19 patients in a single centre during the first epidemic wave and explore potential predictive variables associated with outcomes such as mortality and the need for mechanical ventilation, using baseline clinical parameters. Methodology We conducted a retrospective review of electronic records for demographic, clinical and laboratory data, imaging and outcomes for 500 hospitalised patients between February 20th and May 7th 2020 from Southend University Hospital, Essex, UK. Multivariate logistic regression models were used to identify risk factors relevant to outcome. Results The mean age TRANS of the cohort admitted to hospital with Covid-19, was 69.4 and 290 (58%) were over 70. The majority were Caucasians, 437 (87%) with less than 2 co-morbidities 280(56%). Most common were hypertension HP hypertension MESHD 186(37 %), Cardiovascular disease MESHD 178(36 %) and Diabetes MESHD 128 (26 %), represented in a larger proportion on the mortality group. Mean CFS was 4 with Non Survivors had significantly higher CFS 5 vs 3 in survivors, p<0.001. In addition, Mean CRP was significantly higher 150 vs 90, p<0.001 in Non Survivors. We observed the baseline predictors for mortality were age TRANS, CFS and CRP. Conclusions In this single centre study, older and frailer patients with more comorbidities and a higher baseline CRP and creatinine were risk factors for worse outcomes. Integrated frailty and age TRANS based risk stratification are essential, in addition to monitoring SFR (Sp02/Fi02) and inflammatory markers throughout the disease course to allow for early intervention to improve patient outcomes.

    Background: Understanding the factors associated with disease severity and mortality in Coronavirus disease MESHD (COVID19) is imperative to effectively triage patients. We performed a systematic review to determine the demographic, clinical, laboratory and radiological factors associated with severity and mortality in COVID-19. Methods: We searched PubMed, Embase and WHO database for English language articles from inception until May 8, 2020. We included Observational studies with direct comparison of clinical characteristics between a) patients who died and those who survived or b) patients with severe disease and those without severe disease. Data extraction and quality assessment were performed by two authors independently. Results: Among 15680 articles from the literature search, 109 articles were included in the analysis. The risk of mortality was higher in patients with increasing age TRANS, male TRANS gender TRANS (RR 1.45; 95%CI 1.23,1.71), dyspnea HP dyspnea MESHD (RR 2.55; 95%CI 1.88,2.46), diabetes MESHD (RR 1.59; 95%CI 1.41,1.78), hypertension HP hypertension MESHD (RR 1.90; 95%CI 1.69,2.15). Congestive heart failure HP Congestive heart failure MESHD (OR 4.76; 95%CI 1.34,16.97), hilar lymphadenopathy HP lymphadenopathy MESHD (OR 8.34; 95%CI 2.57,27.08), bilateral lung involvement (OR 4.86; 95%CI 3.19,7.39) and reticular pattern (OR 5.54; 95%CI 1.24,24.67) were associated with severe disease. Clinically relevant cut-offs for leukocytosis HP leukocytosis MESHD(>10.0 x109/L), lymphopenia HP lymphopenia MESHD(< 1.1 x109/L), elevated C-reactive protein(>100mg/L), LDH(>250U/L) and D-dimer(>1mg/L) had higher odds of severe disease and greater risk of mortality. Conclusion: Knowledge of the factors associated of disease severity and mortality identified in our study may assist in clinical decision-making and critical-care resource allocation for patients with COVID-19.

    Currently, the number of patients with COVID-19 has significantly increased. Thus, there is an urgent need for developing treatments for COVID-19. Drug repurposing, which is the process of reusing already-approved drugs for new medical conditions, can be a good way to solve this problem quickly and broadly. Many clinical trials for COVID-19 patients using treatments for other diseases have already been in place or will be performed at clinical sites in the near future. Additionally, patients with comorbidities such as diabetes mellitus HP diabetes mellitus MESHD, obesity HP obesity MESHD, liver cirrhosis MESHD cirrhosis HP, kidney diseases MESHD, hypertension HP hypertension MESHD, and asthma HP asthma MESHD are at higher risk for severe illness from COVID-19. Thus, the relationship of comorbidity disease with COVID-19 may help to find repurposable drugs. To reduce trial and error MESHD in finding treatments for COVID-19, we propose building a network-based drug repurposing framework to prioritize repurposable drugs. First, we utilized knowledge of COVID-19 to construct a disease-gene-drug network (DGDr-Net) representing a COVID-19-centric interactome with components for diseases, genes, and drugs. DGDr-Net consisted of 592 diseases, 26,681 human genes and 2,173 drugs, and medical information for 18 common comorbidities. The DGDr-Net recommended candidate repurposable drugs for COVID-19 through network reinforcement driven scoring algorithms. The scoring algorithms determined the priority of recommendations by utilizing graph-based semi-supervised learning. From the predicted scores, we recommended 30 drugs, including dexamethasone, resveratrol, methotrexate, indomethacin, quercetin, etc., as repurposable drugs for COVID-19, and the results were verified with drugs that have been under clinical trials. The list of drugs via a data-driven computational approach could help reduce trial-and-error in finding treatment for COVID-19.

    BackgroundThe effect of angiotensin-converting enzyme inhibitor/angiotensin receptor blockers (ACEI/ARB) on the COVID-19 remains controversial from clinic evidence. MethodsThis is a retrospective, two-center case series of 198 consecutive COVID-19 patients with a history of hypertension HP hypertension MESHD. ResultsAmong 198 patients, 58 (29.3%) and 16 (8.1%) were on were on ARB and ACEI, respectively. Patients who were on ARB or ACEI/ARB had a significantly lower rate of severe illness MESHD and ARDS when compared with patients treated with ACEI alone or not receiving and RAAS blocker (P<0.05). The Kaplan-Meier survival curve showed that patients with ARB in their antihypertensive regimen had a trend towards a higher survival rate when compared with individuals without ARB (adjusted hazard ratio, 0.27; 95% CI, 0.07-1.02; P = 0.054). The Cox-regression analysis to compared ACEI vs. ARB groups showed a significantly lower mortality rate in the ARB group (adjusted hazard ratio, 0.03; 95% CI, 0.00-0.58; P = 0.02). ConclusionsUsing of ARB was associated with a reduced rate of severe illness MESHD and ARDS, indicating their potential protective impact in COVID-19.

    Background: Previous studies showed that diabetes MESHD was a common comorbidity of COVID-19, but the effects of diabetes MESHD or anti- diabetic MESHD drugs on the mortality of COVID-19 have not been well described. To investigate the outcome of different status (with or without comorbidity) and anti- diabetic MESHD medication before admission of diabetic MESHD patients after SARS-CoV-2 infected MESHD, we collected clinical data of COVID-19 patients from Hubei Province and compared between diabetes MESHD and non-diabetes MESHD.Methods: In this multicenter and retrospective study, we enrolled 1,422 cases of consecutive hospitalized patients from January 21, 2020 to March 25, 2020 at six hospitals in Hubei Province, China. The primary endpoint was in-hospital mortality.Results: Diabetes MESHD patients were 10-years older than non-diabetes MESHD (p<0.001), had higher prevalence SERO of comorbidities such as hypertension HP hypertension MESHD (p<0.001), coronary heart disease MESHD (p<0.001), cerebrovascular disease MESHD ( CVD MESHD) (p<0.001), chronic kidney disease HP chronic kidney disease MESHD ( CKD MESHD) (p=0.007). The incidence of mortality (p=0.003) were more prevalent among the diabetes MESHD group. Further analysis revealed that diabetes MESHD patients who took alpha-glucosidase inhibitor ( AGI MESHD) had lower mortality rate(p<0.01). Multivariable Cox regression showed that male TRANS sex, hypertension HP hypertension MESHD, CKD MESHD, CVD MESHD, age TRANS were risk factors for the mortality of COVID-19. Survival curve revealed that, compared with diabetes MESHD only group, the mortality was increased in diabetes MESHD with comorbidities (p=0.009), but had no significant difference in the non-comorbidity group, p=0.59).Conclusions: Patients with diabetes MESHD had worse outcome when suffered with COVID-19, however, it was not associated with diabetes MESHD itself but the comorbidities. Furthermore, the administration of AGI could reduce the risk of death MESHD in patients with diabetes MESHD.

    Background: SARS-CoV-2 is an emerging pathogen, and coronavirus disease MESHD 2019 (COVID-19) has been declared a global pandemic. We aim to summarize current evidence regarding the risk of death MESHD and the severity of COVID-19 as well as risk factors for severe COVID-19.Methods: The PubMed, Embase, and Web of Science databases as well as some Chinese databases were searched for clinical and epidemiological studies on COVID-19. We conducted a meta-analysis to examine COVID-19-related death MESHD and risk factors for the severity of COVID-19.Results: A total of 55 studies fulfilled the criteria for this review. The case fatality risk ranged from 0 to 61.5%, with a pooled estimate of 3.3%. The risks of ICU admission, acute respiratory distress syndrome MESHD respiratory distress HP syndrome ( ARDS MESHD)and severe COVID-19 were 24.9%, 20.9% and 26.6%, respectively. Factors related to the risk of severe COVID-19 were older age TRANS (MD=10.09, 95% CI:7.03, 13.16), male TRANS sex (OR=1.62, 95% CI:1.32, 1.99), hypertension HP hypertension MESHD (OR=2.34, 95% CI:1.47, 3.73), diabetes MESHD (OR=2.25, 95% CI:1.68, 3.03), chronic renal disease MESHD (OR=3.60, 95% CI:1.53, 8.46), heart disease MESHD (OR=2.76, 95% CI:1.78, 4.30), respiratory disease MESHD (OR=3.74, 95% CI:2.15, 6.49), cerebrovascular disease MESHD (OR=2.21, 95% CI:1.23, 3.98), higher D-dimer levels (SMD=0.62, 95% CI:0.28, 0.96), and higher IL-6 levels (SMD=2.21, 95% CI:0.11, 4.31). However, liver disease MESHD (OR=0.63, 95% CI: 0.36, 1.10) was found to be a nonsignificant predictor of the severity of COVID-19.Conclusions: The case fatality risk of COVID-19 and the risk of severe manifestations were not very high, and variances in the study designs and regions led to high heterogeneity among the studies. Male TRANS sex, older age TRANS, comorbidities such as hypertension HP hypertension MESHD, diabetes MESHD, cardiovascular disease MESHD, respiratory disease MESHD and cerebrovascular disease MESHD could increase the risk of developing a severe case of COVID-19. Laboratory parameters, such as D-dimer and IL-6 levels, could affect the prognosis of COVID-19.

    Background Diabetic MESHD’s patients are supposed to experience higher rates of COVID-19 related poor outcomes. We aimed to determined factors predicting poor outcomes in hospitalized diabetic MESHD patients with COVID-19.Methods This retrospective cohort study included all adult TRANS diabetic MESHD patients with radiological or laboratory confirmed COVID-19 who hospitalized between 20 February 2020 and 27 April 2020 in Alborz province, Iran. Data on demographic, medical history, and laboratory test at presentation were obtained from electronic medical records. Diagnosis of diabetes mellitus HP diabetes mellitus MESHD was self-reported. Comorbidities including cancer MESHD, rheumatism, immunodeficiency MESHD immunodeficiency HP, or chronic diseases of respiratory, liver, and blood SERO were classified as “other comorbidities” due to low frequency. The assessed poor outcomes were in-hospital mortality, need to ICU care, and receiving invasive mechanical ventilation. Self-reported. Multivariate logistic regression models were fitted to quantify the predictors of in-hospital mortality from COVID-19 in patients with DM MESHD.Results Of 455 included patients, 98(21.5%) received ICU care, 65(14.3%) required invasive mechanical ventilation, and 79 (17.4%) dead. In the multivariate model, significant predictors of “death of COVID-19” were age TRANS 65 years or older (OR (95% CI): 2.0 (1.16–3.44), chronic kidney disease HP (CKD) (2.05 (1.16–3.62), presence of “other comorbidities” (2.20 (1.04–4.63)), neutrophil count ≥ 8.0 × 10⁹/L )6.62 (3.73–11.7 ((, Hb level < 12.5 g/dl (2.05 (1.13–3.72) (, and creatinine level ≥ 1.36 mg/dl (3.10 (1.38–6.98)). (All p –values < 0.05). Some of these factors were also associated with other assessed poor outcomes, e.g., need to ICU care or invasive mechanical ventilation.Conclusions Diabetic patients with age TRANS 65 years or older, comorbidity CKD, “other comorbidities”, as well as neutrophil count ≥ 8.0 × 10⁹/L, Hb level < 12.5 g/dl, and creatinine level ≥ 1.36 mg/dl, were more likely to dead after COVID-19. Presence of hypertension HP and cardiovascular disease were associated with none of the poor outcomes.

    The epidemic of COVID-19 has caused an unpredictable and devastated disaster to the public health in different territories around the world. Common phenotypes include fever HP fever MESHD, cough HP cough MESHD, shortness of breath MESHD, and chills HP. With more cases investigated, other clinical phenotypes are gradually recognized, for example, loss of smell, and loss of tastes MESHD. Compared with discharged or cured patients, severe or died patients often have one or more comorbidities, such as hypertension HP hypertension MESHD, diabetes MESHD, and cardiovascular disease MESHD. In this study, we systematically collected and analyzed COVID-19-related clinical phenotypes from 70 articles. The commonly occurring 17 phenotypes were classified into different groups based on the Human Phenotype Ontology (HPO). Based on the HP classification, we systematically analyze three nervous phenotypes (loss of smell, loss of taste, and headache HP headache MESHD) and four abdominal phenotypes ( nausea, vomiting HP nausea, vomiting MESHD vomiting MESHD, abdominal pain HP abdominal pain MESHD, and diarrhea HP diarrhea MESHD) identified in patients, and found that patients from Europe and USA turned to have higher nervous phenotypes and abdominal phenotypes than patients from Asia. A total of 23 comorbidities were found to commonly exist among COVID-19 patients. Patients with these comorbidities such as diabetes MESHD and kidney failure MESHD had worse outcomes compared with those without these comorbidities.

    We aimed to investigate the impact of comorbidity burden on mortality in patients with COVID-19. We analyzed the COVID-19 data from the nationwide health insurance claims of South Korea. Data on demographic characteristics, comorbidities, and mortality records of patients with COVID-19 were extracted from the database. The odds ratios of mortality according to comorbidities in patients with COVID-19 with and without adjustment for age TRANS and sex were calculated. The predictive value of the original Charlson comorbidity index (CCI) and the age TRANS-adjusted CCI (ACCI) for mortality in patients with COVID-19 were investigated using the receiver operating characteristic (ROC) curve analysis. Among 7,590 patients with COVID-19, 227 (3.0%) had died. After age TRANS and sex adjustment, hypertension HP hypertension MESHD, diabetes mellitus HP diabetes mellitus MESHD, congestive heart failure HP congestive heart failure MESHD, dementia HP dementia MESHD, chronic pulmonary disease MESHD, liver, renal, and cancer MESHD were significant risk factors for mortality. The ROC curve analysis showed that ACCI threshold ≥4 yielded the best cut-off point for predicting mortality (area under the ROC 0.92; 95% CI, 0.91–0.94). Our study revealed multiple risk factors that were associated with mortality in patients with COVID-19. The high predictive power of the ACCI for mortality in our results could support the importance of old age TRANS and comorbidities in the severity of COVID-19.
