RESUMO
Background: The role of induction in low-risk, living-donor kidney transplants being treated with tacrolimus, mycophenolate mofetil, and prednisolone is debatable. Materials and Methods: This was a retrospective study that consisted of patients undergoing living kidney transplantation between February 2010 and June 2021 with a related haplomatch donor, with maintenance immunosuppression of tacrolimus, mycophenolate mofetil, and prednisolone. High-risk transplants, such as second or more transplants, immunologically incompatible transplants, and steroid-free transplants, were excluded. Patients were divided into three groups: no induction, basiliximab induction, and thymoglobulin induction, and the outcomes of all three were compared. Results: A total of 350 transplants were performed. There was a significant difference in the recipient sex distribution (P = 0.0373) and the number of preemptive transplants (P = 0.0272) between the groups. Other parameters were comparable. Biopsy-proven acute rejection (BPAR) was significantly less frequent in the thymoglobulin group than in the no-induction (5.3% vs. 17.5%; P = 0.0051) or basiliximab (5.3% vs. 18.8%; P = 0.0054) group. This persisted even after we performed multivariate regression analysis (thymoglobulin vs. no-induction group, P = 0.0146; thymoglobulin vs. basiliximab group, P = 0.0237). There was no difference in BPAR between the basiliximab and no-induction groups. There were no differences in other outcomes between the groups. Conclusion: In a low-risk haplomatch, related, living-donor kidney transplant on tacrolimus, mycophenolate mofetil, and prednisolone, BPAR was significantly lower with thymoglobulin as opposed to no induction or basiliximab induction with a similar short-term patient and death-censored graft survival and infection rates. Basiliximab did not provide any benefit over no induction.
RESUMO
Coronavirus disease 2019 (COVID-19) pandemic is responsible for widespread morbidity and mortality. The vaccination against the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection, the cause of the COVID-19 pandemic, is currently ongoing across the globe. Rapid vaccination is of paramount importance to mitigate this pandemic. Although considered safe in general, these vaccines have their share of rare adverse events. We report a case of antineutrophil cytoplasmic antibody (ANCA)-associated pauci-immune crescentic glomerulonephritis 15 days post 2nd dose of a killed COVID-19 (COVAXIN™ -BB152 V) vaccine. We hypothesize that vaccination triggered a systemic immune response in a susceptible patient to develop ANCA-associated vasculitis (AAV), leading to rapidly progressive glomerulonephritis (RPGN).
