Filter by: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.
Multicenter, randomized, placebo-controlled, parallel, blinded, interventional, treatment clinical trial with two arms. Population: 500 Hospitalized patients with pneumonia derived from COVID-19 (Coronavirus Disease-19), either confirmed by RT-PCR (Real Time polymerase chain reaction), or suggested by typical findings on the computed tomography scan symptomatic. Experimental group: nitazoxanide 500mg 8 / 8 hours for 5 days. Control group: placebo 8/8 hours for 5 days.
The principal objective of the CONFIDENT trial is to assess the efficacy of two units (400-500 mL in total) of convalescent plasma, as compared to Standard of Care (SoC), to reduce day-28 mortality in patients with SARS-CoV-2 pneumonia who require mechanical ventilation.
This study generates robust clinical data to train ML/AI algorithms of the Sponsor's imPulse™ Una full-spectrum e-stethoscope for digital diagnostic feature synthesis of symptomatic SARS-CoV-2/COVID-19 biosignatures for rapid and accurate mass screening.
The Corona virus disease 2019 (COVID-19) pandemic is currently involving all parts of the world. Several risk factors for critical illness and death from the disease have been proposed. However, it is still unclear if the observed associations between different comorbidities and chronic medications and severe COVID-19 disease and mortality is different from associations between the same factors and other severe diseases requiring intensive care unit (ICU) -care. This is important since some of the observed risk factors are very common in the aged who, by age alone, are more prone to a more severe course of any disease. By combining several registries, this study will compare, on several comorbidities such as hypertension and diabetes , the first 2000 cases of COVID-19 patients receiving critical care in Sweden to a Swedish sepsis-cohort and a Swedish adult respiratory distress syndrome (ARDS) -cohort.
This is a phase IIIa, prospective, open-label, randomized, parallel-group study designed to evaluate the efficacy and safety of oral colchicine plus standard therapy versus standard therapy in the clinical course of SARS-CoV-2 infection, in a population group with moderate COVID-19 compromise and requiring hospitalization.Aproximately 120 subjects meeting all inclusion and not inclusion criteria will be randomized to receive either Colchicine plus standard treatment or only standard treatment for 15 days
The aim of this study is to analyze if the use of oral antimicrobial solutions and dentifricies are able to reduce the SARS-CoV-2 load in the saliva and oral mucosa. It will be allocated hospitalized patients positive for SARS-CoV-2 (confirmed by RT-PCR of nasopharynx swab tests) and with signs and symptoms of COVID-19. These patients will be divided into two groups: patients enrolled in negative pressure rooms (NPR), and patients enrolled in intensive care units (ICU) with orotracheal intubation. These two groups will receive interventions with oral antimicrobial solutions or dentifrices, containing different compounds. Saliva and oral mucosa swabs will be collected before the intervention, immediately after the intervention, and after 30min and 1h. The primary outcome is to verify if these products can reduce the SARS-CoV-2 load in the saliva and oral mucosa at these time periods, detected by the measurement of the viral load and the fold-reduction.
The world is currently experiencing a coronavirus (CoV-2) pandemic. A new (SARS)-CoV infection epidemic began in Wuhan, Hubei, China, in late 2019; originally called 2019- nCoV the virus is now known as SARSCoV- 2 and the disease it causes COVID-19. Previous CoV epidemics included severe acute respiratory syndrome (SARS)-CoV, which started in China in 2003 and Middle East respiratory syndrome (MERS)-CoV in the Middle East, which started in 2012. The mortality rates were >10% for SARS and >35% for MERS. The direct cause of death is generally due to ensuing severe atypical pneumonia and ensuing acute respiratory distress syndrome (ARDS). Pneumonia also is generally the cause of death for people who develop influenza, although the mortality rate is lower (1%-3% for the influenza A H5N1 pandemic of 1918-1919 in the United States). Risk factors for a poor outcome of SARS-CoV-2 infection have so far been found to include older age and co-morbidities including chronic cardiovascular and respiratory conditions and current smoking status. In May 2020, the FDA authorized the emergency use of remdesivir for treatment of COVID-19 disease based on topline date of two clinical trials, even though an underpowered clinical trial did not find significant improvement in COVID- 19 patients treated with remdesivir. Nevertheless, remdesivir is the first and so far, only approved treatment for COVID-19. Additionally further trials and clinical observations have not found a significant benefit of other antiviral drugs. Although the results of several studies are still pending, there is still a desperate need for an effective, safe treatment for COVID-19. Aviptadil, which is a synthetic form of Human Vasoactive Intestinal Polypeptide (VIP), might be beneficial in patients at risk of developing ARDS. Nonclinical studies demonstrate that VIP is highly concentrated in the lung, where it reduces inflammation.
This is a phase 1 clinical trial to verify the safety and efficacy of DW-MSC in COVID-19 patients. A total of 9 subjects are randomly allocated. Subjects who meet the final inclusion and exclusion criteria are randomized to the test groups (low-dose group and high-dose group) or control group (placebo group) in a ratio of 1:1:1. Subjects assigned to the test groups were administered intravenously once with 5 x 10^7cells of DW-MSC for the low-dose group or 1 x 10^8cells for the high-dose group after registration. Subjects assigned to the control group were administered with placebo in the same manner as the test drug (DW-MSC). At this time, all of the existing standard co-treatment are allowed. DW-MSC is adjunct therapy to standard therapy. This clinical trial is a double-blind trial, in which a randomized method will be used. To maintain the double-blindness of the study, statistician who do not participate in this study independently generate randomization code. Subjects will be randomized to the test groups (low-dose group and high-dose group) or the control group (placebo group) in a 1:1:1 ratio. After the completion of the trial, the randomization code will be disclosed after unlocking the database and unblinding procedures. Follow Up period: observed for 28 days after a single administration
