Active clinical trials for "Severe Acute Respiratory Syndrome"

This study inquires about the development of Telogen effluvium following the SARS-CoV-2 infection

All health care workers at the Department of Anesthesiology and Intensive Care at UMC Ljubljana will be tested for SARS-CoV2 with nasal swab test and blood withdrawal for SARS-CoV2 antibodies. At the same time a questionnaire with epidemiological anamnesis, risky contacts and the use of personal protective equipment will be fulfilled.

In this prospective longitudinal cohort the investigators reported the clinical, and biological characteristics of all critically ill patients admitted in the pediatric intensive care unit (PICU) of Bicêtre Hospital during the 2019 coronavirus disease (COVID-19) pandemics. Patients were older than 37 weeks of gestational age. No upper limit was set as the unit was transiently converted into a pediatric "adult COVID-19" intensive care unit.

A new strain of coronavirus that caused severe respiratory disease in infected individuals was initially identified in China's Wuhan City in December 2019. Severe acute respiratory distress syndrome coronavirus-2 (SARS-CoV-2), which was responsible for the corona virus infectious disease-2019 (COVID-19).The World Health Organization declared that COVID-19 was a Public Health Emergency of International Concern on January 30,2020. The impact of COVID-19 in liver recipients remains largely unknown but accumulating experience is going on. Liver transplant recipients should have been classified as a risk group and should have received regular surveillance for COVID-19 throughout the pandemic. Some reports suggest decreasing immunosuppression for infected recipients, if no recent rejection episodes. Paradoxically, others suggest that a reactive immune response might be the cause for severe tissue damage, and that immunosuppression might be protective from the postulated cytokine storm. Some studies stated that the LT patients who are permanently on immunosuppressants could be particularly susceptible to SARS-CoV-2, and their prognosis could be worse in comparison to the normal population. They recommended that LT recipients should be closely monitored for SARS-CoV-2. The LT society of India (LTSI) highlighted the potential of LT recipients as asymptomatic carriers and source of viral spread, and that SARS-CoV-2 can be transmitted to LT recipients. There are insufficient data on the relationship between immunosuppressive therapy and COVID-19 in LT recipients during this pandemic. However, the Beijing working party for liver transplantation suggested that LT recipients who were infected with SARS-CoV-2 should be treated with steroids for a short period to reduce the severity of pneumonia. They also suggested that immunosuppressive therapies should be continued for both patients with mild COVID-19 and those who were not infected by the virus, and calcineurin inhibitor treatment dosage should be reduced in moderate to severe cases. Neutralizing antibodies (NAbs) play an important role in virus clearance and have been considered as a key immune product for protection or treatment against viral diseases. Virus-specific NAbs, induced through either infection or vaccination, have the ability to block viral infection. SARS-CoV -2 specific NAbs reached their peak in patients from day 10-15 after the onset of the disease and remained stable thereafter in the patients. Antibodies targeting on different domains of S protein, including S1, RBD, and S2, may all contribute to the neutralization. Al-Rajhi Liver Center is the only liver transplantation center in Upper Egypt that performed only 51 living donor liver transplantation (LDLT) cases since 2014, but it was used as isolation Hospital for COVID-19 cases from March to July, 2020. Communication with liver transplant cases during that period was via Telemedicine. Resuming usual Hospital activity as Tertiary Liver Center occurred in 15 August 2020. Similarly, other Hospitals in Egypt were designated as COVID-19 isolation Hospitals.

SARS-CoV-2, the virus that causes COVID-19, is currently a global public health problem, declared a pandemic by the World Health Organization, which today has more than one million deaths in the world, of which , 30,000 approximately belong to Colombia, being the country number 11 with the highest number of deaths. The most common symptoms related to this disease are fever, cough, dyspnea, myalgia, headache, diarrhea and rhinorrhea. COVID-19 is characterized by immune system dysfunction and hyperinflammation causing acute respiratory distress syndrome, macrophage activation, and coagulopathy. The clinical course for SARS-CoV-2 in most cases is mild, but approximately 14% of cases can be severe. In pneumonia caused by SARS-CoV-2, the lung lining is known to alter the composition of the lung microbiome, in addition to lymphocyte damage that can promote the growth of bacteria to initiate bacterial pneumonia, and it is estimated that the prevalence of coinfection / superinfection reaches 50% among deaths from COVID-19. Coinfection between different microorganisms and SARS-CoV-2 is a serious problem in the COVID-19 pandemic, and there is still little information on this. It is for this reason that the researchs propose to develop this research project that will allow to understand the possible mechanisms associated with the development of bacterial coinfection / superinfection in patients diagnosed with COVID-19, which will allow expanding the panorama of knowledge towards a better and adequate treatment in these patients, as well as detection of biomarkers or clinical phenotypics that may be useful in the diagnosis, based on evidence. It is important to note that these results are of clinical importance since we will try to identify biomarkers or changes in the lung microbiome that allow doctors to early identify patients at risk of developing coinfection and thus initiate early treatments or preventive measures, which allow the improvement of clinical outcomes in patients. Results will be presented in a timely manner at national and international conferences and in peer-reviewed, indexed, high-impact journals.

Analysing ths spread of COVID-19 epidemics in a timely manner is key to implementing public health control strategies. The investigators propose to analyse a large set of laboratory SARS-CoV-2 RT-PCR data to explore potential links between Ct values and epidemic parameters.

This study examines the presence, severity and natural history of dysphagia and dysphonia in the post-extubation and severely unwell COVID-19 patient.

By Jan 7, 2020, Chinese scientists had isolated a novel coronavirus, from patients with virus-infected pneumonia. The WHO designated later this virus as COVID-19 (coronavirus disease 2019). This exponential pandemic coronavirus infection is responsible for severe forms in 15 to 20%, for critical ill requiring ventilation in 5% and for mortality in 2%. Algeria was part of the 13 top priority countries identified by WHO based on their direct links and volume of travel to the infected provinces in China. It is known that some predisposing conditions lead to a worse outcome with coronavirus. In China, the overall case-fatality rate was 2.3%, but was higher in patients with diabetes (7.3%). In Italy, the most common comorbidities associated with death from COVID-19 were hypertension (73.8%) and diabetes (33.9%). The US Centers for Disease Control and Prevention suggests diabetes is the most common comorbidity in COVID-19 cases. In the largest cohort NHS England study, death from COVID-19 was strongly associated with uncontrolled diabetes (after full adjustment, HR 2.36). The West Algerian CORODIAB-13 study aims is (1) to assess the prevalence of diabetes among hospitalized patients with Covid-19, (2) to describe the phenotypic characteristics of patients with diabetes, and (3) to identify the parameters specific to the diabetic which are associated with severe forms. In the future, this study will provide answers for two main questions Why diabetics are more at risk of developing Covid-19 infection? Why diabetics are at high risk of developing severe forms?
