Antibody Responses in Contacts of COVID-19 Patients

COVID-19

After several cases of pneumonia with an unfamiliar etiology were observed at the end of 2019, the National Health Commission of China released more details about the epidemic in early 2020. The pathogen was identified as a novel coronavirus and named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as it has a phylogenetic similarity to SARS-CoV. Since then, SARS-CoV-2 has spread rapidly and the resulting coronavirus disease 2019 (COVID-19) has been declared a public health emergency of international concern (PHEIC) by the World Health Organization (WHO). SARS-CoV-2 is highly contagious, and there has not yet been any vaccine or effective treatment that has received approval. So, the best solution for controlling the pandemic will be the simultaneous application of preventive methods, sensitive diagnostic approaches, and using current available drugs, while still developing novel treatments. Coronaviruses are enveloped, non-segmented, single positive-stranded RNA viruses with round or oval particles and a diameter of 50-200 nm. Coronavirus subfamily is divided into four genera: α, β, γ and δ according to serotype and genomic characteristics.

Worldwide Trends on COVID-19 Research After the Declaration of COVID-19 Pandemic

COVID-19

On 11th of March 2020, WHO characterized COVID-19 infection as a Pandemic. After the COVID-19 infection is declared as a Pandemic there was an outburst regarding COVID-19 Research. The Research interest led to registration of Interventional and Observational studies world wide. There are constant efforts by Health care workers to seek information regarding the Interventional and Observational studies which can help in decision making regarding effective handling of COVID-19 infected patients. It is also important to track on the happenings in various frontiers of COVID-19 Research in view of historical interest and clinical relevance. This Observational Cross sectional study aims to explore the completed Researches in WHO-compliant registries to understand the trends of COVID-19 Research. This study aims to get a birds eye view of ongoing COVID-19 Research scenario worldwide. This study results can directly benefit the worldwide Academicians and Health Care Professionals to understand the ongoing COVID-19 Research trends.

The Evaluation of Hemostasis in Hospitalized COVID-19 Patients

COVID-19

Coronavirus disease 2019 (COVID-19), a viral respiratory illness caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been shown to predispose patients to thrombotic diseases (venous and arterial) with reported rates in hospitalized patients between 17-40%. The influence of SARS-CoV-2 infection on the coagulation is hypothesized to be regulated by platelet activation, proinflammatory cytokines, endothelial cell injury and stasis. The elevated levels of d-dimer and fibrinogen and clinical signs of organ damage point to a significant hypercoagulable state. The latter induces a high risk for micro-thrombi and multi-organ ischemia. Therefore, early detection and a comprehensive understanding of the influence of the virus on the coagulation and platelet pathways are essential to address this epidemic. It is critical at this time to make all efforts possible to optimize our available technology to care for COVID-19 patients who are at risk for thrombotic disease through appropriate choice, dosing, and laboratory monitoring of antithrombotic therapy. The investigators hypothesize that COVID-19 is a heightened prothrombotic/hypercoagulability state that can be characterized using platelet function testing and thrombelastography. More information is required to study the effect of COVID-19 on coagulation and platelet pathways to develop effective antithrombotic treatment strategies. This is a multi-center center, non-interventional study enrolling patients who are COVID-19 positive or who have tested negative showing indication of the disease (high D-dimer and positive lung imaging). The study specific laboratory assessments will be obtained at baseline (closest to time of hospitalization), Day 3, and Day 8 from baseline and at hospital discharge. Laboratory measurements for TEG 6S , platelet aggregation, T-TAS, urinary thromboxane, genotyping, serum and plasma biomarkers will be analyzed . In-hospital and clinical follow-up data will be entered into a COVID registry Patients will be followed for clinical events during hospitalization, and up to 6 months after discharge. Patients (n=100) hospitalized with at least one of the following will be enrolled. With a confirmed diagnosis of COVID-19 infection using a positive RT- PCR or a positive IgG antibody test prior to or during hospitalization or With a negative COVID-19 RT-PCR test but with symptoms of possible COVID-19 infection and: an elevated D-dimer and/or positive imaging results showing unilateral or bilateral pneumonia or ground-glass opacity in lungs.

Prognostic Factors in Patients Admitted to an Urban Teaching Hospital With COVID-19 Infection

COVID-19

As of 27th May 2020, approximately 5.7 million people worldwide are known to have been infected with COVID-19 coronavirus and more than 350,000 have died (1). The severity of this viral disease for an individual is associated with a widespread perturbation of immune, physiological and metabolic parameters (2, 3). These whole body changes could be considered characteristic of a systemic inflammatory response to tissue injury and it has been long recognised that a large and ongoing systemic inflammatory response is associated with the development of multiple organ failure and infective disease (4, 5). One of the cardinal signs of severe COVID-19 infection is a marked systemic inflammatory response (2). This response bears striking similarity to the systemic inflammatory response experienced by patients undergoing major elective surgical resections for cancer (6, 7). Indeed, the systemic inflammatory response and the associated metabolic stress has been most well characterised in major elective surgery, where the relationship between the magnitude of the post-operative systemic inflammatory response and the development of post-operative complications is now well recognised, as is the effect of patient comorbidity on this relationship (8, 9). Such work has informed therapeutic manoeuvres including minimally invasive surgery, pre-operative optimisation (e.g. anaesthesia, nutrition and steroids) and enhanced recovery protocols. The aim of the present study was to examine whether routinely collected clinicopathological characteristics of patients with COVID-19 on admission were informative on the immune and metabolic stress experienced by patients with COVID-19 and whether such characteristics were informative on subsequent outcome.

Covid-19 Infection in After Vaccination

Covid19

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in Wuhan, China. It rapidly spread, resulting a global pandemic in March 2020. Globally, till 27 August 2021, there have been 214,468,601 confirmed cases of COVID-19, including 4,470,969 deaths, reported to WHO. With the absence of curative treatment for COVID-19 infection the development of safe and effective vaccines is critical to ending the COVID-19 pandemic. The Pfizer/BioNtech Comirnaty vaccine was listed for WHO Emergency Use Listing (EUL) on 31 December 2020. The SII/Covishield and AstraZeneca/AZD1222 vaccines (developed by AstraZeneca/Oxford and manufactured by the State Institute of India and SK Bio respectively) were given EUL on 16 February. The Janssen/Ad26.COV 2.S developed by Johnson & Johnson, was listed for EUL on 12 March 2021. The Moderna COVID-19 vaccine (mRNA 1273) was listed for EUL on 30 April 2021 and the Sinopharm COVID-19 vaccine was listed for EUL on 7 May 2021. The Sinopharm vaccine is produced by Beijing Bio-Institute of Biological Products Co Ltd, subsidiary of China National Biotec Group (CNBG). The Sinovac-CoronaVac was listed for EUL on 1 June 2021. As of 25 August 2021, a total of 4,953,887,422 vaccine doses have been administered. In large, randomized-controlled trials, vaccines were found to be safe and efficacious in preventing symptomatic, laboratory-confirmed COVID-19. However, a small percentage of fully vaccinated persons will develop symptomatic or asymptomatic infections with SARS-CoV-2, the virus that causes COVID-19. A vaccine breakthrough infection is defined as the detection of SARS-CoV-2 RNA or antigen in a respiratory specimen collected from a person ≥14 days after receipt of all recommended doses of an FDA-authorized COVID-19 vaccine. A total of 10,262 SARS-CoV-2 vaccine breakthrough infections had been reported from 46 U.S. states and territories as of April 30, 2021. Among these cases, 6,446 (63%) occurred in females, and the median patient age was 58 years (interquartile range = 40-74 years). Based on preliminary data, 2,725 (27%) vaccine breakthrough infections were asymptomatic, 995 (10%) patients were known to be hospitalized, and 160 (2%) patients died.
