Outcomes of Kidney Transplantation Among COVID-19 Recovered Patients in a Single Transplant Center.

BACKGROUND: The COVID-19 pandemic significantly lowered kidney transplantation (KT) rates worldwide, and studies regarding outcomes of patients who developed COVID-19 infection before KT are limited, especially in low to middle-income countries.

BACKGROUND: To determine the 1-year graft and patient survival of kidney transplant recipients who recovered from COVID-19 infection before KT.

METHODS: We retrospectively reviewed all adult end-stage renal disease patients who underwent KT at the National Kidney and Transplant Institute from June 2020 through October 2021. Transplant parameters, graft and patient survival, pretransplant COVID-19 infection, and post-KT infectious complications were recorded. Data was analyzed using two-tailed descriptive statistical tests.

RESULTS: Of the 219 recipients, 23 (11%) had COVID-19 infection within 1 to 16 months before KT. The mean age of KT recipients was 36 years (range, 25-57), and 61.9% had chronic glomerulonephritis as primary renal disease. The mean duration from COVID-19 recovery to KT was 79 days (range, 21-207). There was no significant difference in the 1-year biopsy-proven acute rejection in the 2 groups, at 4.5% vs 12.5% for the COVID-19 and non-COVID-19 group, respectively. Both the 1-year graft and patient survival were similar in the COVID-19 and non-COVID-19 groups at 98.4% vs 100% and 100% vs 98.44%, respectively.

CONCLUSION: There was no significant difference in biopsy-proven acute rejection, 1-year graft, and patient survival among patients who had a prior COVID-19 infection vs those who did not. Kidney transplantation appears safe when performed at least 1 month from COVID-19 infection.
