Serology to Covid for Recording Exposures and Evaluating Needs

As the global and pandemic spread of the novel coronavirus (SARS-CoV-2, COVID-19) continues, many knowledge gaps remain with regard to the epidemiology and transmission of infection, as well as the normal immunological responses after viral exposure. Cincinnati had its first confirmed case of COVID-19 on March 14, 2020, and despite extensive shelter-in-place and social distancing efforts, community spread continues at over 150-200 new cases per week. As new residents and fellows arrive in July 2020 to Cincinnati Children's Hospital Medical Center (CCHMC), many of whom come from metropolitan areas across the country, it is imperative that we determine the current prevalence of infection, measure the cumulative incidence of infection over the next 12-24 months, investigate the normal antibody patterns after infection, and help elucidate what constitutes a protective immunological response. We have a unique but time-limited opportunity to optimally track the epidemiology and natural history of SARS-CoV-2 infection among trainees at CCHMC, including risk factors for transmission and immunological recovery. SCREEN will investigate epidemiological and immunological features of SARS-CoV-2 virus infection within the cohort of CCHMC residents and fellows who have patient contact. By collecting and analyzing weekly serial samples for SARS-CoV-2 (nasal swab for virus by PCR) and monthly serological exposure (serum antibodies by ELISA), we will determine the prevalence and cumulative incidence of infection by SARS-CoV-2; we will also document the antibody responses over time and identify cases of apparent viral recrudescence or re-infection.

Angiotensin-(1,7) Treatment in COVID-19: the ATCO Trial

Background: A novel Coronavirus (SARS-CoV-2) described in late 2019 in Wuhan, China, has led to a pandemic and to a specific coronavirus-related disease (COVID-19), which is mainly characterized by a respiratory involvement. While researching for a vaccine has been started, effective therapeutic solutions are urgently needed to face this threaten. The renin-angiotensin system (RAS) has a relevant role in COVID-19, as the virus will enter host 's cells via the angiotensin-converting enzyme 2 (ACE2); RAS disequilibrium might also play a key role in the modulation of the inflammatory response that characterizes the lung involvement. Angiotensin-(1-7) is a peptide that is downregulated in COVID-19 patient and it may potentially improve respiratory function in this setting. Methods/Design: The Investigators describe herein the methodology of a randomized, controlled, adaptive Phase II/Phase III trial to test the safety, efficacy and clinical impact of the infusion of angiotensin-(1-7) in COVID-19 patients with respiratory failure requiring mechanical ventilation. A first phase of the study, including a limited number of patients (n=20), will serve to confirm the safety of the study drug, by observing the number of the severe adverse events. In a second phase, the enrollment will continue to investigate the primary endpoint of the study (i.e. number of days where the patient is alive and not on mechanical ventilation up to day 28) to evaluate the efficacy and the clinical impact of this drug. Secondary outcomes will include the hospital length of stay, ICU length of stay, ICU and hospital mortality, time to weaning from mechanical ventilation, reintubation rate, secondary infections, needs for vasopressors, PaO2/FiO2 changes, incidence of deep vein thrombosis, changes in inflammatory markers, angiotensins plasmatic levels and changes in radiological findings. The estimated sample size to demonstrate a reduction in the primary outcome from a median of 14 to 11 days is 56 patients, 60 including a dropout rate of 3% (i.e. 30 per group), but a preplanned recalculation of the study sample size is previewed after the enrollment of 30 patients. Expected outcomes/Discussion: This controlled trial will assess the efficacy, safety and clinical impact of the Angiotensin-(1-7) infusion in a cohort of COVID-19 patients requiring mechanical ventilation. The results of this trial may provide useful information for the management of this disease.

Clinical Characterization Protocol for Severe Infectious Diseases (CCPSEI)

This is a standardized protocol for the rapid, coordinated clinical investigation of severe or potentially severe acute infections by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Participants with acute illness suspected to be caused by SARS-CoV-2 (COVID-19) will be enrolled. This protocol has been designed to enable data and biological samples to be prospectively collected and shared rapidly in a globally-harmonized sampling schedule. Multiple independent studies can be easily aggregated, tabulated and analyzed across many different settings globally. The protocol is the product of many years of discussion among international investigators from a wide range of scientific and medical. Recruitment under this protocol has been initiated in response to Middle Eastern Respiratory Syndrome coronavirus (MERS-CoV) in 2012-2013, Influenza H7N9 in 2013, viral hemorrhagic fever (Ebolavirus) in 2014, Monkeypox & MERS-coronavirus in 2018, Tick-borne encephalitis virus (TBEV) in 2019 and COVID-19 in 2020. Participants may be newly identified through healthcare system or public health access, under quarantine, or in isolation care in outpatient or inpatient settings relevant to the Johns Hopkins University School of Medicine. Other locations may adopt this study concurrently, under a deferred review, or cooperatively. The existence of this protocol would ensure a timely, comprehensive epidemiologic and clinical characterization of the initial cases of COVID-19 in a mounting pandemic. The World Health Organization (WHO) recognized the need for standardized data collection for the epidemiology, immunology and clinical characteristics of these novel pathogens, and established the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) network in 2011. At the core of the protocol are a standardized schedule, structure and content of clinical, laboratory and microbiologic data collection, supplemented by domain-specific components (e.g., acute respiratory infection, viral hemorrhagic fever). The timepoints of this protocol will also be aligned with a separate multi-center institutional review board (IRB) approved protocol to describe patients with emerging infectious diseases that present to military treatment facilities within the United States.

Can Remote Photoplethysmography Be Used for Contactless Vital Sign Acquisition in a Healthcare Setting? A Prospective Comparative Study.

Contactless and widely available health monitoring technologies are of growing interest in the context of the worldwide COVID-19 pandemic. Remote photoplethysmography (rPPG) is a well-studied technology that interprets variations in skin colour related to blood flow which, when analysed with complex mathematical algorithm, generates vital sign readings. This technology has been refined and embedded in a smartphone app designed to acquire heart rate, respiratory rate and oxygen saturation using a front-facing smartphone camera. Preliminary data comparing the accuracy of smartphone rPPG readings with conventional vital sign monitor readings are promising; however, less than 5% of the population studied in the app development phase had oxygen saturation levels below 95% making it impossible to ensure reliability in these populations. The goal of this study is to compare readings acquired using this rPPG app with the readings from hospital grade, Health Canada approved vital signs monitors used in healthcare settings with a focus on subject with low oxygen saturations. We will also study other sociodemographic and clinical features that may influence the accuracy of the readings. This will be achieved by recruiting consenting adults presenting to care in acute care settings and a designated COVID outpatient clinic. Vital signs will be acquired using the rPPG app and conventional hospital vital sign monitors simultaneously. Readings will be repeated within 2-5 minutes when time permits. Statistical analysis will be performed to analyze the findings and determine the accuracy and precision of the rPPG app readings. It is expected that the vital sign readings acquired with the rPPG app will be almost identical to those acquired using hospital-grade monitors for all subjects regardless of age, gender, skin colour, COVID status and relevant comorbidities.
