Abstract
Background: Kidney transplantation activity at the University Hospital of Guadeloupe was briefly interrupted at the onset of the COVID-19 pandemic, reflecting the global impact of this health crisis on organ transplantation. This study assessed patient and graft recovery in 335 recipients transplanted between 2013 and 2023, comparing those transplanted before 2020 and after the resumption of activity. The objective was to evaluate changes in recipient profiles, surgical parameters, and post-transplant outcomes following this disruption. Methods: This retrospective cohort included all kidney transplants performed at the University Hospital of Guadeloupe over a ten-year period. Most patients (70%) received transplants before 2020, with 30% afterward. All grafts were ABO-compatible, and 98.2% were from deceased donors. Trends in transplant activity were analyzed to identify variations over time, with a peak observed in 2018, followed by a decline until 2021 and a progressive recovery from 2022. Comparative analyses were performed to examine disparities in donor and recipient characteristics, ischemia durations, and outcomes between the two periods. Results: After 2020, recipients were more likely to be elderly (≥70 years), immunized, obese, have heterozygous sickle cell disease, or have polycystic kidney disease (p < 0.05). Mean cold ischemia time decreased (p = 0.009), while warm ischemia time increased (p < 0.001), reflecting procedural and logistical adaptations. Graft survival remained stable, with 97.5% at 6 months and 89.8% at 4 years for transplants before 2020, versus 100% and 96.9%, respectively, after 2020 (p = 0.160). Patient survival did not differ significantly between periods (p = 0.199). Independent factors associated with mortality included recipient age ≥ 60 years, diabetes, graft failure, transplantation before 2020, cold ischemia time ≥ 1200 min, and graft pyelonephritis. Conclusions: Despite the temporary suspension of activity and an increased proportion of transplants with expanded criteria after 2020, graft recovery and patient survival were not adversely affected. These findings suggest that kidney transplantation in Guadeloupe demonstrated strong resilience and capacity for adaptation during and after the COVID-19 crisis, maintaining outcomes comparable to the pre-pandemic period.
