简要总结

This will be a randomized trial of maintenance versus reduction in immunosuppression in adult patients (age >18 years old) with functioning renal transplants admitted to hospital with confirmed COVID-19 disease.

详细描述

The optimal management of immunosuppression in renal transplant patients with COVID-19 disease is unclear. On one hand, many centers advocate reduction of immunosuppression in infected patients, with the rationale that such an approach will unleash the anti-viral T-cell response. However, on the other hand, some centers advocate there may be rationale to maintain baseline immunosuppression in order to mitigate against development of an uncontrolled over-activation of the immune response. The investigators propose to address this knowledge gap by performing a randomized clinical trial that will test formal comparisons of maintenance versus reduction in immunosuppression.
