Coronavirus infection, also known as COVID-19, has become a global pandemic with over 3 million cases and 250,000 deaths worldwide. Coronaviruses (CoV) belong to a family of viruses that predominately infect mammals and birds, affecting their lungs, intestinal tract, liver and nervous systems. Prior to the discovery of the current novel coronavirus strain (SARS-CoV-2), there were six different strains that are known to infect humans, which includes the virus that caused the severe acute respiratory syndrome (SARS) pandemic in 2002. In humans, the majority of severe illness from SARs and COVID-19 is due to inflammation of the lungs and pneumonia. Pregnancy poses a significantly increased risk of viral pneumonia and during SARS more pregnant women required intensive care and breathing support, and the proportion of deaths was higher when compared to non-pregnant adults. Furthermore, kidney failure and development of abnormal blood clotting disorders, which occurs during severe infection, is more common in pregnancy and the associated changes in blood vessels extend to the placentas of infected pregnant women, thus potentially affecting the fetus. This makes pregnant women affected by the virus at high risk of developing severe complications. Fortunately, there have been a number of biomarkers identified that are associated with illness severity. These include, specialised white blood cells, blood clotting cells and constituents, as well as other measures of heart and kidney function. We propose that these biomarkers are important correlates of clinical disease severity and prognosis in pregnant and postnatal women. This knowledge has the potential to help clinicians during this pandemic to better manage and care for their patients.
Severe acute respiratory syndrome coronavirus 2 (COVID-19) poses substantial challenges for health care systems. With a vastly expanding amount of publications on COVID-19, clinicians need evidence synthesis to produce guidance for handling patients with COVID-19.
Coronavirus Disease 19 (COVID-19) is a global pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Severe disease occurs in 15% of the cases with COVID-19 and may progress to critical disease in only 5% of the cases with a high risk of mortality. Critical disease may present as acute respiratory failure secondary to Acute Respiratory Distress Syndrome (ARDS) and is caused by the body's hyper-immune response to the virus in the form of a cytokine storm syndrome (CSS). There is currently no effective anti-viral treatment against SARS-CoV-2 and the mainstay of treatment is supportive. Co-trimoxazole (combination of trimethoprim and sulphamethoxazole in a 1:5) ratio is a Sulphur containing anti-folate bactericidal antibiotic indicated for the treatment of respiratory tract infections. It has been around for over 60 years and is inexpensive and readily available with a good safety profile. It has a rapid onset of action with excellent bioavailability and lung penetration. In addition to having antimicrobial properties co-trimoxazole have immunomodulatory and anti-inflammatory properties and may be a potential treatment option for cytokine storm syndrome mediated severe COVID-19. This open-label randomized controlled trial will be conducted in the department of medicine at Bangabandhu Sheikh Mujib Medical University (BSMMU), Anwar Khan Modern Medical college and Mughda Medical College Hospital (DMCH), Dhaka for a duration of 6 months following approval of this protocol. It will recruit at least 94 consecutive adults (18 years or older) patients with clinically suspected COVID-19 and severe illness as per WHO criteria. After taking informed written consent patients will be randomly assigned in a 1:1 ratio to either oral co-trimoxazole in addition to standard therapy or standard therapy alone. Baseline characteristics, changes in the physiological and biochemical parameters like (SpO2/FiO2 ratio, respiratory rate, body temperature and C - reactive protein), length of hospital stay, side effects of drugs, requirement for ventilatory support (non-invasive and invasive ventilation) and in-patient mortality between the two groups will be compared. Conclusion If the results from this clinical trial demonstrate the beneficial effects of co-trimoxazole in severe COVID-19 patients it could be used widely, thereby reducing the need for respiratory support and potentially saving thousands of lives in developing nations with limited resources where healthcare may be easily overwhelmed.
Coronavirus disease 2019 (COVID‐19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), which first appeared in China, in December 2019 and is now spreading worldwide and poses a great threat to public health. In 12th July 2020, the total number of cases worldwide was about 13 million cases with case fatality rate of 4.4% and in Egypt the total cases was 81158 and case fatality rate was 4.6%. (1,2). In recent years, novel coronaviruses emerge periodically in different areas around the world. Severe acute respiratory syndrome coronavirus (SARS‐CoV) occurred in 2002, which reportedly infected 8422 people with about 10% case fatality rate (3). Middle East respiratory syndrome coronavirus (MERS‐CoV) was first identified in 2012 in Saudi Arabia, bringing a total of 1401 MERS‐CoV infections, and about 35% case fatality rate (1). All the infection cases and recent epidemics show that coronaviruses impose a continuous threat to human beings and the economy as they emerge unexpectedly, spread easily, and lead to catastrophic consequences. As the number of recovered patients with COVID-19 continues to be increasing, the strength and duration of immunity after infection is an important point to be studied. Moreover, understanding this issue is a critical point for controlling this epidemic as they are the key for herd immunity and for informing decisions on how and when to ease physical distancing restrictions and to be ready for other waves of the infection. There is currently no evidence if the people who have recovered from COVID-19 have antibodies and protected from a second attack of infection or future wave of this pandemic or not. Therefore, we will carry out a longitudinal study of immunity in recovered patients to assess SARS-Cov2 patients' risk for future reinfection.
COVID-19 is impacting on health systems in Brazil and worldwide. Reducing the risk of clinical deterioration and prolonged disease duration in hospitalized patients with COVID-19 may alleviate the burden caused by the pandemic. Melatonin (N-acetyl-5-methoxytryptamine) has demonstrated antiapoptotic, antioxidative, and anti-inflammatory roles and has been suggested as a potential protector against organ injuries and even mediate lower mortality rates after polymicrobial sepsis in animal models. Melatonin agonists may modulate protective effects against acute lung injury and play a clinical role in individuals with SARS-CoV-2 infection. The investigators proposed a clinical trial testing the effects of ramelteon 8mg in hospitalized patients with COVID-19.
The number of COVID-19 cases has been growing exponentially, so that the industrialized economies are facing a significant shortage in the number of ventilators available to meet the demands imposed by the disease. Noninvasive ventilatory support can be valuable for certain patients, avoiding tracheal intubation and its complications. However, non-invasive techniques have a high potential to generate aerosols during their implementation, especially when masks are used in which it is virtually impossible to completely prevent air leakage and the dispersion of aerosols with viral particles. In this context, a helmet-like interface system with complete sealing and respiratory isolation of the patient's head can allow the application of ventilatory support without intubation and with safety and comfort for healthcare professionals and patients. This type of device is not accessible in Brazil, nor is it available for immediate import, requiring the development of a national product. Meanwhile, a task force under the coordination of the School of Public Health (ESP) and Fundação Cearense de Apoio à Pesquisa (FUNCAP), with support from SENAI / FIEC and the Federal Universities of Ceará (UFC) and the University of Fortaleza (UNIFOR) advanced in the development of a prototype and accessory system capable of providing airway pressurization through a helmet-type interface, which was called the Elmo System.
Healthcare workers play a critical role in fighting the pandemic, not only by managing the patients' health clinically, but also by implementing adequate measures for infection prevention and control in healthcare facilities. This puts healthcare workers at a greater risk of acquiring the disease. COVID-19 is caused by Severe Acute Respiratory Syndrome Coronavirus -2 (SARS-CoV-2) and many people can be infected with it asymptomatically and undetectably. Serology is an antibody test that provides additional information to polymerase chain-reaction (PCR) testing as it is the only way to reliably establish the fraction of the population that was infected . Seroconversion is the development of antibodies in the blood which can confirm suspected cases after the fact and reveal who was infected but asymptomatic and never realized it. Antibodies are specific proteins created as the body's response to the infection and this test is essential for detecting infected individuals with few or no symptoms at all.
The objectives of this study are (1) to determine the ex vivo neutralizing capacity and the longevity of SARS-CoV-2-specific Ab responses and (2) to measure the memory B-cell responses in a cohort of health care workers (HCW) recovering from severe, mild or asymptomatic infection. By focusing on HCW, a population that is at risk for re-infection during a second epidemic wave, the correlation between nAb levels and protection is investigated.
COVID-19 is causing a serious viral pandemic in terms of health and social impact. To date, no treatment has yet demonstrated Strong efficacy in treating the infectious disease (COVID-19). Pulmonary administration of Interferon (IFN) type I is a therapeutic strategy with high potential,due to higher local concentrations and minimal adverse effects. Type I interferons (including IFN-α and IFN-β) are antiviral defence cytokines and also have the potential to negatively modulate IFN Type II and IL-6 dependent cytokine storm, the latter being induced in the late forms of COVID-19. In vitro, IFN-β were more effective on COVID-19 than IFN-α. In existing preliminary studies, only patients receiving IFN type I modulators have a decrease in viral carriage and a rapid reversal. The purpose of this project is to assess in hospitalized patients with oxygen for COVID 19, the clinical efficacy on oxygen requirements of the addition of inhaled Interferon type I compared to the control arm .
