Can hyperimmune anti-CMV globulin substitute for convalescent plasma for treatment of COVID-19?

ABSTRACT: Information on treatment of COVID-19 infection in renal transplant recipients is scarce, especially in symptomatic patients and patients with recent major clinical events. This group of patients suffers from different opportunistic infections which may coexist with COVID-19. Currently available expert opinions suggest reduction of immunosuppression therapy for renal transplant recipients with symptomatic COVID-19 infection with either antiviral drugs, hydroxychloroquine and/or azithromycin. Inspired by our experience in treatment of CMV pneumonia and literature data on the potential benefit of convalescent plasma for treatment of different viral diseases we suggest use of the hyperimmune anti-CMV gamma globulins in addition to other available therapies. Besides the immunosuppression reduction which is supposed to be beneficial, immunoglobulins with their immunomodulatory effects and possible antiviral role, may increase a possibility for favorable outcome.

Project description:BACKGROUND:There is currently no treatment known to alter the course of coronavirus disease 2019 (COVID-19). Convalescent plasma has been used to treat a number of infections during pandemics, including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle Eastern respiratory syndrome coronavirus (MERS-CoV) and now severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). OBJECTIVES:To summarize the existing literature and registered clinical trials on the efficacy and safety of convalescent plasma for treating coronaviruses, and discuss issues of feasibility, and donor and patient selection. SOURCES:A review of articles published in PubMed was performed on 13 July 2020 to summarize the currently available evidence in human studies for convalescent plasma as a treatment for coronaviruses. The World Health Organization International Clinical Trials Registry and clinicaltrials.gov were searched to summarize the currently registered randomized clinical trials for convalescent plasma in COVID-19. CONTENT:There were sixteen COVID-19, four MERS and five SARS reports describing convalescent plasma use in humans. There were two randomized control trials, both of which were for COVID-19 and were terminated early. Most COVID-19 reports described a potential benefit of convalescent plasma on clinical outcomes in severe or critically ill patients with few immediate adverse events. However, there were a number of limitations, including the concurrent use of antivirals, steroids and other treatments, small sample sizes, lack of randomization or control groups, and short follow-up time. Data from SARS and COVID-19 suggest that earlier administration probably yields better outcomes. The ideal candidates for recipients and donors are not known. Still, experience with previous coronaviruses tells us that antibodies in convalescent patients are probably short-lived. Patients who had more severe disease and who are earlier in their course of recovery may be more likely to have adequate titres. Finally, a number of practical challenges were identified. IMPLICATIONS:There is currently no effective treatment for COVID-19, and preliminary trials for convalescent plasma suggest that there may be some benefits. However, research to date is at high risk of bias, and randomized control trials are desperately needed to determine the efficacy and safety of this therapeutic option.
