Filter by:By using recent data on hospital attendance and COVID-19 laboratory tests, available within two NHS trusts in Nottingham and Cardiff we will enable the calculation of the risk of developing COVID-19 infection after attending an outpatient hospital appointment. This will assist in the restart planning when resuming face to face outpatient radiology appointment.
many patients with confirmed infection with COVID-19 suffer from different symptoms and signs of gastrointestinal symptoms
Although the direct damage from the viruses contributes to the initiation of the disease, the cytokine storm caused by COVID-19 plays a vital role in the development of acute lung injury and adult respiratory distress syndrome. IL-6, a kind of pleiotropic cytokine, is expressed by immune cells such as DC, monocytes, macrophages, B cells, and subsets of activated T cells, as well as by non-immune cells like fibroblasts, epithelial cells, and keratinocytes
The main manifestation of COVID-19 is acute hypoxemic respiratory failure (AHRF). In patients with AHRF, the need for invasive mechanical ventilation is associated with high mortality. Prone positioning (PP) is a recommended strategy for patients with moderate to severe acute respiratory distress syndrome (ARDS) undergoing invasive mechanical ventilation. Early PP combined with High Flow Oxygen Therapy may benefit spontaneous breathing patients with AHRF due to COVID-19 as recently reported in Jiangsu. Our hypothesis is that early PP combined with High Flow Oxygen Therapy in patients with AHRF due to COVID-19 improves oxygenation.
Covid-19 is associated with the onset of anti-SARS-CoV-2 antibodies; in a majority of patients, neutralizing antibodies are detected. However, the long-term persistence of such protective antibodies is not known. The investigators will explore patients with a proven Covid-19 (positive PCR) 6 and 12 months after the diagnosis to determine whether neutralizing antibodies are still detected. The investigators will determine whether this persistance varies according to - the severity of the Covid-19 - a treatment by steroids during the covid-19. This will help to anticipate whether a second wave of infection is possible in a non-naive population.
Administration of Zinc and resveratrol or double placebo for a period of 5 days and will be monitored for a 14 day period in covid-19 positive patients in an outpatient setting
This study objective is to collect tear and blood samples from individuals with positive SARS-COV2 diagnosis and test those samples for the presence of various SARS-COV2 viral antigens and autoantibodies.
Currently, there is no specific treatment or vaccine for SARS-CoV-2 available, some drugs are being investigated as treatment, but the effect is unknown. A strategy and other method used before, in coronavirus pandemic (SARS-CoV in 2003 and MERS-CoV in 2012), was the use of immune (convalescent) plasma. Passive administration of antibodies through convalescent plasma transfusion may offer the only short-term strategy available to confer immediate immunity and being a relative immediately resource available for treat COVID-19 disease. This research proposes the passive administration of antibodies through the transfusion of convalescent plasma, in patients with severe COVID-19 disease.
Methods: Out of 2000 kidney transplant recipients in our center in Kuwait, collecting data was started for all COVID-19-positive kidney transplant recipients till August 2020. Clinical features, management details and both patient and graft outcomes were reported.
Currently there are no proven treatments or vaccines for COVID-19 and care of the COVID patients is largely supportive involving treatment of symptoms such as fever with antipyretics, secondary bacterial chest infection with antibiotics and meticulous management of comorbid conditions. Several repurposed and new drugs have been investigated for treatment of COVID-19, however, none have been confirmed to be efficacious. These drugs include the antimalarials (chloroquine and hydroxychloroquine), antivirals such as remdesivir and favipiravir and antiretroviral combination therapies such lopinavir/ritonavir. There is emerging evidence to support the use of COVID convalescent plasma for the treatment of COVID-19. There is need to leverage the blood transfusion services in countries and this is beginning to happen on the continent.
