    Background The novel severe acute respiratory syndrome coronavirus 2 MESHD (SARS-CoV-2) has subsequently spread worldwide. The number of death MESHD has increased rapidly. However, the possible risk factors that lead to death in critical inpatients with coronavirus disease MESHD 2019 (COVID-19) are not yet fully known. This study was to explore the risk factors for mortality of critical inpatients with COVID-19.Methods In this single-centered, retrospective study, we enrolled 113 critical patients with COVID-19 in Renmin Hospital of Wuhan University between Feb 1, 2020 and Mar 15, 2020. Data were collected using a standard method including clinical records and laboratory findings. Outcomes of survivors and death were compared.Results A total of 113 critical patients (from 29 to 95 years) with COVID-19 were recruited, 50 (44.25%) died and 63 recovered (55.75%). The proportion of patients with ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in the death group than the recovery group (24.0% vs 4.4%; p = 0.021), and was higher among myocardial damage MESHD cases than non-myocardial damage cases (26.1% vs 4.3%; p = 0.013). Multivariate analysis confirmed four independent predictors related to mortality of COVID-19: age > 70 yrs (HR 1.84, 95% CI 1.03–3.28), initial neutrophil count more than 6.5 × 109/L (HR 3.43, 95% CI 1.84–6.40), C-reactive protein greater more than 100 mg/L (HR 1.93, 95% CI 1.04–3.59), and lactate dehydrogenase more than 300 U/L (HR 2.90, 95% CI 1.26–6.67). Immunoglobulin treatment (HR 0.39, 95% CI 0.21–0.73) can reduce the risk of death MESHD. There was no significant difference in the QT interval between patients with and without hydroxychloroquine treatment.Conclusions Old age TRANS (> 70 years), neutrophilia HP, C-reactive protein greater more than 100 mg/L and lactate dehydrogenase more than 300 U/L are high-risk factors for mortality of critical patients with COVID-19. The incidence of ventricular arrhythmia HP ventricular arrhythmia MESHD was higher in deceased patients than survivors.

    Introduction: Hydroxychloroquine and its combination with azithromycin have been suggested to improve viral clearance in patients with COVID-19, but its effect on clinical outcomes remains uncertain. Methods and analysis: We describe the rationale and design of an open-label pragmatic multicentre randomised (concealed) clinical trial of 7 days of hydroxychloroquine (400 mg BID) plus azithromycin (500 mg once daily), hydroxychloroquine 400 mg BID, or standard of care for moderately severe hospitalised patients with suspected or confirmed COVID-19 (in-patients with up to 4L/minute oxygen supply through nasal catheter). Patients are randomised in around 50 recruiting sites and we plan to enrol 630 patients with COVID-19. The primary endpoint is a 7-level ordinal scale measured at 15-days: 1)not hospitalised, without limitations on activities; 2)not hospitalised, with limitations on activities; 3)hospitalised, not using supplementary oxygen; 4)hospitalised, using supplementary oxygen; 5)hospitalised, using high-flow nasal cannula or non-invasive ventilation; 6)hospitalised, on mechanical ventilation; 7)death. Secondary endpoints are the ordinal scale at 7 days, need for mechanical ventilation and rescue therapies during 15 days, need of high-flow nasal cannula or non-invasive ventilation during 15 days, length of hospital stay, in-hospital mortality, thromboembolic MESHD events, occurrence of acute kidney injury HP acute kidney injury MESHD, and number of days free of respiratory support at 15 days. Secondary safety outcomes include prolongation of QT interval MESHD on electrocardiogram, ventricular arrhythmias HP ventricular arrhythmias MESHD, and liver toxicity MESHD. The main analysis will consider all patients with confirmed COVID-19 in the groups they were randomly assigned. Ethics and dissemination: This study has been approved by Brazil's National Ethic Committee (CONEP) and National Health Surveillance Agency (ANVISA). An independent data monitoring committee will perform interim analyses and evaluate adverse events throughout the trial. Results will be submitted for publication after enrolment and follow-up are complete, as well as presented and reported to local health agencies. identifier: NCT04322123
