    BACKGROUND Chloroquine is used for the treatment of COVID-19 patients. However, efficacy of the chloroquine has been under discussion. Variability of clinical outputs of the drug application requires implementation of a companion diagnostic that would allow monitoring responsiveness to chloroquine. The first line of such markers would be markers already used in clinics. Analysis of reported mechanisms of COVID-19 and chloroquine may lead to such markers.METHODS Systemic analysis of molecular mechanisms and markers engaged by chloroquine and COVID-19 virus was performed. The networks of regulatory mechanisms were explored for an intersection and relevance to clinical markers.RESULTS Reported here systemic analysis describes the intersection of molecular mechanisms of chloroquine and processes engaged by COVID-19. 266 nodes provide insight into the mechanisms of chloroquine impact on the infection MESHD and represent a pool of companion diagnostic markers. As an example, an intersection with the markers of heart arrhythmia MESHD arrhythmia HP retrieved 19 nodes. Thirteen of them were reported in human plasma SERO: levels of albumin, amyloid precursor protein, and endoglin correlate with adverse cardiac effects.CONCLUSIONS Reported nodes are the candidate markers for companion diagnostic of the chloroquine application to COVID-19 patients. Some of these markers are already used in the clinic and their interpretation may contribute to monitoring for adverse effects of chloroquine.

    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.
