Successful Kidney Transplantation of Two Patients with Donors Positive for Severe Acute Respiratory Syndrome Coronavirus Infection
OBM transplantation(2023)
摘要
Despite preventative measures, including vaccination, severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection may result in severe illness, particularly in immunosuppressed transplant recipients. This has had a negative impact on organ donation and transplantation rates. However, the risk of transmission from SARS-CoV-2 positive donors to kidney transplant recipients is unknown. We describe 2 cases of successful kidney transplantation from SARS-CoV-2 positive donors. Case 1: 38-year old unvaccinated female, established on haemodialysis for 1 year, with underlying reflux nephropathy. Donor tested SARS-CoV-2 positive on polymerase chain reaction testing with a cycle threshold (CT) value of 29 initially. Sequential testing demonstrated a rise in CT value (37.8), aiding the decision to proceed. The recipient was high immunological risk and received a controlled category 3 donation after circulatory death (DCD) kidney transplant. She had immediate graft function and did not develop SARS-CoV-2 infection. Case 2: 63-year old female, with diabetes mellitus and hypertension. She was low immunological risk and for pre-emptive transplantation. The donor was SARS-CoV-2 positive with a CT value of 41.5 and was subsequently negative. Decision was made to proceed with a donation after brainstem death (DBD) transplant. The recipient had immediate graft function and did not develop SARS-CoV-2 infection. We report 2 cases of successful transplantation from SARS-CoV-2 positive donors, without severe infection, with no transmission seen in the recipients post-operatively. Decisions to proceed were primarily made on clinical grounds with assistance from RT-PCR CT values, making this a useful additional tool in determining suitability of organ donation in people who are SARS-CoV-2 positive.
