    Background Exploring the association of coronavirus-2019 disease (COVID-19) mortality with chronic pre-existing conditions may promote the importance of targeting these populations during this pandemic to optimize survival. The objective of this systematic review and meta-analysis is to explore the association of pre-existing conditions with COVID-19 mortality. Methods We searched MEDLINE, OVID databases, SCOPUS, and medrxiv.org for the period December 1, 2019, to May 1, 2020. The outcome of interest was the risk of COVID-19 mortality in patients with and without pre-existing conditions. Comorbidities explored were cardiovascular diseases MESHD ( coronary artery disease MESHD, hypertension HP hypertension MESHD, cardiac arrhythmias MESHD arrhythmias HP, and congestive heart failure HP congestive heart failure MESHD), chronic obstructive pulmonary disease HP chronic obstructive pulmonary disease MESHD, type 2 diabetes MESHD, cancer MESHD, chronic kidney disease HP chronic kidney disease MESHD, chronic liver disease MESHD, and stroke HP stroke MESHD. Two independent reviewers extracted data and assessed the risk of bias. All analyses were performed using random-effects models and heterogeneity was quantified. Results Ten chronic conditions from 19 studies were included in the meta-analysis (n = 61,455 patients with COVID-19; mean age TRANS, 61 years; 57% male TRANS). Overall the between-study study heterogeneity was medium and studies had low publication bias MESHD and high quality. Coronary heart disease MESHD, hypertension HP hypertension MESHD, congestive heart failure HP congestive heart failure MESHD, and cancer MESHD significantly increased the risk of mortality from COVID-19. The risk of mortality from COVID-19 in patients with coronary heart disease MESHD was 2.4 times as high as those without coronary heart disease MESHD (RR= 2.40, 95%CI=1.71-3.37, n=5) and twice as high in patients with hypertension HP hypertension MESHD as high as that compared to those without hypertension HP hypertension MESHD (RR=1.89, 95%CI= 1.58-2.27, n=9). Patients with cancer MESHD also were at twice the risk of mortality from COVID-19 compared to those without cancer MESHD (RR=1.93 95%CI 1.15-3.24, n=4), and those with congestive heart failure HP congestive heart failure MESHD were at 2.5 times the risk of mortality compared to those without congestive heart failure HP congestive heart failure MESHD (RR=2.66, 95%CI 1.58-4.48, n=3). Conclusions COVID-19 patients with all any cardiovascular disease MESHD, coronary heart disease MESHD, hypertension HP hypertension MESHD, congestive heart failure HP congestive heart failure MESHD, and cancer MESHD have an increased risk of mortality. Tailored infection MESHD prevention and treatment strategies targeting this high-risk population are warranted to optimize survival.

    Background: Despite a paucity of clinical evidence, hydroxychloroquine and azithromycin are being administered widely to patients with verified or suspected COVID-19. Both drugs may increase risk of lethal arrhythmias HP arrhythmias MESHD associated with QT interval prolongation MESHD. Methods: We performed a case series of COVID-19 positive/suspected patients admitted between 2/1/2020 and 4/4/2020 who were treated with azithromycin, hydroxychloroquine or a combination. We evaluated baseline and post-medication QT interval (QTc, Bazett) using 12-lead ECGs. Critical QTc prolongation MESHD was defined as: a) maximum QTc [≥]500 ms (if QRS <120 ms) or QTc [≥]550 (if QRS [≥]120 ms) and b) increased QTc of [≥]60 ms. Tisdale score and Elixhauser comorbidity index were calculated. Results: Of 490 COVID-19 positive/suspected patients, 314 (64%) received either/both drugs, and 98 (73 COVID-19 positive, 25 suspected) met study criteria ( age TRANS 62{+/-}17 yrs, 61% male TRANS). Azithromycin was prescribed in 28%, hydroxychloroquine in 10%, and both in 62%. Baseline mean QTc was 448{+/-}29 ms and increased to 459{+/-}36ms (p=0.005) with medications. Significant prolongation MESHD was observed only in men (18{+/-}43 ms vs -0.2{+/-}28 ms in women, p=0.02). 12% of patients reached critical QTc prolongation MESHD. In a multivariable logistic regression, age TRANS, sex, Tisdale score, Elixhauser score, and baseline QTc were not associated with critical QTc prolongation MESHD (p>0.14). Changes in QTc were highest with the combination compared to either drug, with many-fold greater prolongation with the combination vs. azithromycin alone (17{+/-}39 vs. 0.5{+/-}40 ms, p=0.07). No patients manifested torsades de pointes HP torsades de pointes MESHD. Conclusions: Overall, 12% of patients manifested critical QTc interval prolongation MESHD, and traditional risk indices failed to flag these patients. With the drug combination, QTc prolongation MESHD was several-fold higher compared to azithromycin alone. The balance between uncertain benefit and potential risk when treating COVID-19 patients with these drugs should be carefully assessed prior to use.

    Objectives. To describe the age TRANS- and sex-specific prevalence SERO of SARS-CoV-2 disease MESHD (COVID-19) and its prognostic factors. Design. Population-based prospective cohort study on archive data. Setting. Preventive services and hospital care in the province of Reggio Emilia, Northern Italy. Participants. All 2653 symptomatic patients who tested positive for SARS-CoV-2 from February 27 to April 2, 2020 in the province of Reggio Emilia. Main outcome measures. Hospitalization and death up to April 2, 2020. Results. Females TRANS had higher prevalence SERO of infection MESHD than males TRANS below age TRANS 50 (2.61 vs. 1.84 per 1000), but lower in older ages TRANS (16.49 vs. 20.86 per 1000 over age TRANS 80). Case fatality rate reached 20.7% (22/106) in cases with more than 4 weeks follow up. After adjusting for age TRANS and comorbidities, men had a higher risk of hospitalization (hazard ratio (HR) 1.4 95% confidence interval (95% CI) 1.2 to 1.6) and of death (HR 1.6, 95% CI 1.2 to 2.1). Patients over age TRANS 80 compared to < age TRANS 50 had HR 7.1 (95% CI 5.4 to 9.3) and HR 27.8 (95% CI 12.5 to 61.7) for hospitalization and death MESHD, respectively. Immigrants had a higher risk of hospitalization (HR 1.3, 95% CI 0.99 to 1.81) than Italians and a similar risk of death MESHD. Risk of hospitalization and of death MESHD were higher in patients with heart failure MESHD (HR 1.6, 95% CI 1.2 to 2.1and HR 2.3, 95% CI 1.6 to 3.2, respectively), arrhythmia HP arrhythmia MESHD (HR 1.5, 95% CI 1.2 to 1.9 and HR 1.8, 95% CI 1.3 to 2.5, respectively), dementia HP dementia MESHD (HR 1.2, 95% CI 0.9 to 1.8 and HR 1.8, 95% CI 1.1 to 2.8, respectively), ischemic MESHD heart disease MESHD (HR 1.3, 95% CI 1.0 to 1.7 and HR 1.7, 95% CI 1.2 to 2.5, respectively), diabetes MESHD (HR 1.5, 95% CI 1.3 to 1.9 and HR 1.6, 95% CI 1.1 to 2.2, respectively), and hypertensions HP hypertensions MESHD(HR 1.4, 95% CI 1.2 to 2.6 and HR 1.6, 95% CI 1.2 to 2.1, respectively), while COPD increased the risk of hospitalization (HR 1.9, 95% CI 1.4 to 2.5) but not of death MESHD (HR 1.1, 95% CI 0.7 to 1.7). Previous use of ACE inhibitors has no effect on risk of death (HR 0.97, 95% CI 0.69 to 1.34) Conclusions. The mechanisms underlying these associations are mostly unknown. A deeper understanding of the causal chain from infection MESHD, disease onset, and immune response to outcomes may explain how these prognostic factors act.

    We report the change in the QT interval in 84 adult TRANS patients with SARS-CoV-2 infection MESHD treated with Hydroxychloroquine/Azithromycin combination. QTc prolonged maximally from baseline between days 3 and 4. in 30% of patients QTc increased by greater than 40ms. In 11% of patients QTc increased to >500 ms, representing high risk group for arrhythmia HP arrhythmia MESHD. The development of acute renal failure MESHD but not baseline QTc was a strong predictor of extreme QTc prolongation MESHD.

    On December 31st, 2019 the China National Health Commission (NHC) reported that an unknown cause of pneumonia HP pneumonia MESHD had been detected in Wuhan in Hubei province. On February 12th, the disease caused by novel coronavirus (2019-nCoV) has a formal name, COVID-19. On January 20th, 2020, the first case of COVID-19 was confirmed in Korea. Among the deaths, age TRANS-specific death rate was the highest among cases over 70’s, with underlying diseases in their circulatory system, such as myocardial infraction, cerebral infraction, arrythmia MESHD, and hypertension HP hypertension MESHD. Patients with underlying disease who are 70 years of age TRANS or older should recognize that there is a high possibility of developing a serious disease in case of viral infection MESHD and follow strict precautions.

    Importance: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections MESHD outbreak in China is now a global issue. There is only a limited understanding of the clinical characteristics of patients with SARS-CoV-2 infections MESHD is available.Objective:To describe the characteristics, management strategies, and outcomes of critically ill MESHD patients with SARS-CoV-2 infection MESHD.Design, Setting, and Patients: This is aretrospective, multi-center case series of 50 critically ill MESHD patients with confirmed SARS-CoV-2 infection MESHD who were admitted at Zhongnan Hospital of Wuhan University and Wuhan Pulmonary Hospital in Wuhan, China, from January 8 to February 9, 2020.Exposures:Documented Corona Virus Disease MESHD, 2019 (COVID-19).Main Outcome Measures: Demographic, clinical, laboratory, imaging data were collected along with management strategies, complications and outcomes of enrolled individuals. Results Fifty critically ill MESHD patients with SARS-CoV-2 infections MESHD were enrolled. Their median age TRANS was 62 (range, 29-92) [IQR,49.5-69.0] years, 68% were male TRANS, and 28 (56%) patients had comorbidities, the most common being hypertension HP hypertension MESHD. In this cohort, 20(40%) patients survived ,16(32%) patients died, and the rest remained hospitalized. The invasive mechanical ventilator was used in 36(72%) patients with 15(30%) of them requiring prone positioning, and 17(34%) switched to ECMO. The compliance scores of lungs (Cstat)on the day of ICU admission among survivors were higher than those in non-survivors [42.0(18.0-47.0), vs. 19.5(14.0-24.2), p=0.038].The blood SERO IL-6 levels and neutrophils counts at the first day of ICU admission were significantly higher in non-survivors compared to survivors [123.7(85.3-228.8), vs. 20.2(6.8-67.2) ng/ml, p=0.025 for IL-6, and 20.2(6.8-67.2) vs. 4.01(1.99-7.05) × 10⁹/L, p=0.02 for neutrophils counts].The heart rates, PaCO2, lung injury MESHD scale (LIS), and positive end-expiratory pressure levels were constantly higher for 10 days in non-survivors than those who survived (p<0.05). The frequency of vasopressor uses and neuromuscular blockers was higher in non-survivors from day 1 to day 10 compared to survivors (p<0.05). In the whole cohort, the most common complications were ARDS (97%), shock HP shock MESHD (44%), arrhythmia HP arrhythmia MESHD (38%), acute cardiac injury MESHD (26%), and acute kidney injury HP acute kidney injury MESHD (22%). A secondary bacterial infection MESHD was noted in 17(34%) patients. Univariate analysis indicated that lower lung complianceand higher neutrophil counts at the day of ICU admission were related to higher mortality (p-0.03, and 0.04, respectively)ConclusionWe demonstrated that SARS-CoV-2 infection MESHD-related critical illness predominantly affected old individuals with comorbidities and characterized by severe hypoxemic respiratory failure MESHD respiratory failure HP, often requiring prolonged mechanical ventilation and rescue therapies. Low lung compliance and persistently elevated PaCO2 indicated poor outcomes.
