This study is part of the current global emergency scenario due to infection with Coronavirus, SARS-CoV-2 as indicated by the international taxonomy. Study aim is to investigate the possibility of the presence of the virus within the seminal fluid and in the urine of infected patients, both during the acute phase and remotely. Current evidences show that Coronaviruses can be present inside the testicle and sperm in other species, such as in feline and avian models. In human beings, current researches have mixed results regarding the presence of SARSCoV-2 in urine, as several studies with a large sample found no traces of the same with Real-Time Reverse method Transcriptase - Polymerase Chain Reaction or with method of nucleic acid amplification. By contrast, in just over 6% of 58 patients with Real Time Polymerase Chain Reaction method have found the presence of SARS-CoV-2 in the urine, even at a distance from the last negative nasopharyngeal swab. Given the topicality of the problem, our study has the objective of specifically researching the presence and possible persistence over time of SARS-CoV-2 in seminal fluid and urine. A saliva sample will also be collected as a control. At the moment there are no studies in literature that tested this possibility. If confirmed, it would lead to find out another potential method of transmission, the sexual one, in asymptomatic patients or apparently no longer infectious with negative buffer. The rationale for our study is the evidence that in other species this type of transmission by coronaviruses is possible and that at present it has not been verified in mankind. The relevance of the study would be both in the case of a negative result, as the first study in its generally, both in the case of a positive result, due to the possibility of introducing new prevention measures in the long run.
In December 2019, a novel coronavirus, now called COVID-19, emerged as a global health threat from Wuhan, China. Within weeks, the contagious virus spread within and between communities, causing a lower respiratory tract infection dominated by symptoms of fever, cough and sore throat. The incubation period was estimated at between 5 to 7 days, but could last as long as 14 days. Although COVID-19 causes a mostly mild and self-limiting disease, respiratory involvement has been reported in about 5% of the population, requiring supplemental oxygen and even ventilatory support to relieve hypoxia. Alveolar damage, fibrosis and consolidation have been reported in radiologic and post-mortem studies. Existing data suggest a mortality rate of COVID-19 is approximately 1-2%, higher among individuals with pre-existing comorbidities and in healthcare systems with suboptimal access to ventilatory support. Given its high transmissibility, COVID-19 has quickly spread across the globe within a short interval. By 27 April 2020, over 3 million people around the world have been diagnosed with COVID-19, and more 200,000 have succumbed to the disease. As a proportion of patients manifest mild or no symptoms, these numbers are likely an underestimate of the actual number of patients with COVID-19. More disconcertingly, patients are known to shed viruses despite mild or no symptoms, making it essential that a collective approach against COVID-19 incorporate active pharmacological treatment to prevent or mitigate virus pathogenesis prior to its potential evolution to cause respiratory distress. To date, clinical trials have focused on the treatment of hospitalised patients diagnosed with COVID-19; only few have examined the clinical benefits of pharmacological agents despite few compelling in vitro data. The relatively high transmission of COVID-19 in a closed dormitory environment of migrant workers in Singapore presents a real-life scenario where a prophylaxis treatment could reduce the impact of the disease. In Singapore, there are well grounded concerns an excess in cases could pose the possibility of strain in healthcare system and mentally drain her workers. The availability of an effective prophylaxis treatment is highly desirable to potentially reduce this burden. Data from the current study could also have implications on how future outbreaks in high-density areas should be managed, especially when residents are subjected to quarantine and isolation.
The purpose of this clinical trial is to determine the efficacy of Previfenon® (EGCG) to prevent COVID-19, enhance systemic immunity, and decrease the frequency and intensity of selected symptoms when used as pre-exposure chemoprophylaxis to SARS-CoV-2.
Patients with COVID-19 associated ARDS and mechanical ventilation have a high mortality. Part of the disease is an activation of the coagulation system which seems to contribute to clotformation in the pulmonary bloodstream. Recently we implemented an algorithm applying higher doses of heparins (LMWH). However, this approach could not inhibit clotformation enough. Bivalirudin could prevent clotformation better and support dissolving existing clots. Therefore, we want to compare 50 patients with the standard treatment with 50 patients under bivalirudin treatment which we normally apply in patients with a HIT-syndrome. Our primary outcome measure is oxygenation reflected as P/F ratio.
In december 2019, SARS-CoV2 and its clinical manifestations, COVID-19, appeared in China and caused a pandemic. It led decision makers to prioritize emergency and intensive care dedicated to infection management. Other conditions, such as cancer screening, diagnosis, and treatment, may have been delayed during the containment period. Consequences of this "distraction effect" are being.
Inflammatory diseases favour the onset of venous thromboembolic events in hospitalized patients. Thromboprophylaxis with a fixed dose of heparin/low molecular weight heparin (LMWH) is recommended if concomitant inflammatory disease. In severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) pneumonia an inflammation-dependent thrombotic process occurs and platelet activation may promote thrombosis and amplify inflammation, as indicated by previous experimental evidence , and the similarities with atherothrombosis and thrombotic microangiopathies. Antiplatelet agents represent the cornerstone in the prevention and treatment of atherosclerotic arterial thromboembolism, with limited efficacy in the context of venous thromboembolism. The use of purinergic receptor P2Y12 inhibitors in pneumococcal pneumonia may improve inflammation and respiratory function in humans. There are no validated protocols for thrombosis prevention in Covid-19. There is scientific rationale to consider a P2Y12 inhibitor for the prevention of thrombosis in the pulmonary circulation and attenuation of inflammation. This is supported by numerous demonstrations of the anti-inflammatory activity of P2Y12 inhibitors and the evidence of improvement in respiratory function both in human and experimental pathology. Prasugrel could be considered as an ideal candidate drug for Covid-19 patients because of higher efficacy and limited Interactions with drugs used in the treatment of Sars-CoV2. The hypothesis underlying the present study project is that in Covid-19 platelet activation occurs through an inflammation-dependent mechanism and that early antithrombotic prophylaxis in non-critical patients could reduce the incidence of pulmonary thrombosis and respiratory and multi-organ failure improving clinical outcome in patients with SARS-CoV2 pneumonia. The prevention of thrombogenic platelet activity with a P2Y12 inhibitor could be superior to fixed dose enoxaparin alone. The proposed treatment is feasible in all coronavirus disease 2019 (COVID-19) patients, regardless of the treatment regimen (antivirals, anti-inflammatory drugs, antibiotics), except for specific contraindications.
The following two mechanisms that explain the ability of measles vaccine to cause partial protection against COVID-19. The first is that measles vaccine may increase the ability of the immune system to fight off pathogens other than measles due to the generated bystander immunity that would enhance the overall immunity against the new coronavirus. The second is that SARS-CoV-2 is proven to have structure similarities with measles, which may cause cross-reactivity and immunity between measles vaccines and COVID-19, leading to partial protection against COVID-19 in vaccinated subjects
We aim to understand the mechanism of olfactory dysfunction in COVID-19.
The investigators reviewed the charts of SARS-CoV-2 patients with pneumonia and moderate to severely elevated CRP and worsening hypoxemia who were treated with early, short-term dexamethasone.
