SARS-CoV-2 infection in the immediate post-transplant period: A report of five kidney transplant recipients

Introduction: The severe acute respiratory syndrome coronavirus 2 pandemic caused a negative impact on transplantation worldwide. One of the complexities is the management of the immunosuppression and anti-viral medication in transplant recipients. Herein we describe our experience managing five patients with coronavirus disease 2019 (COVID-19) immediately after kidney transplant. Description: we describe a series of five transplant recipients. Two were submitted to a low immunological risk induction immunosuppression: one developed severe disease, the other developed critical disease. The remaining three were submitted to a high immunologic risk immunosuppression: one developed mild disease, but approximately two months after diagnosis developed moderate COVID-19; another developed severe COVID-19; the remaining patient developed critical illness and perished. Both patients with critical COVID-19 developed bacterial and fungal superinfections in the Intensive Care Unit. All eligible patients were submitted to remdesivir and dexamethasone. The anti-metabolite was reduced or suspended. Despite worsening kidney function during the acute phase, kidney replacement therapy was only needed in one patient and the average serum creatinine at the time of discharge was lower that the pre-COVID-19 nadir. Discussion: There is still no definitive answer on whether solid organ transplant recipients carry a higher risk for morbimortality. Risk factors for the general population can also affect their outcome. The prolonged viral shedding in recipients may explain the irregular evolution of the patient who developed COVID-19 months after the initial diagnosis. The reduction of immunosuppression can be problematic in early post-transplant, but no apparent signs of rejection were noted. Literature addressing this specific context is scarce and studies are needed to clarify the optimal management of these patients.
