Kidney transplant recipients are at higher risk for COVID-19 complications. This study examines the epidemiology and outcome of PCR-documented SARS-CoV-2 infection in KTR patients from March 2020 to May 2022. Early administration of monoclonal antibodies and a lower Charlson Comorbidity Index are associated with better outcomes.
Kidney transplant recipients (KTR) are at increased risk for COVID-19-associated complications. We aimed to describe the evolving epidemiology and outcome of PCR-documented SARS-CoV-2 infection in KTR followed at our institution from March 2020 to May 2022. The primary endpoint was hospitalization for COVID-19-related symptoms or death within 28 days from diagnosis. Overall, 243 cases were included of which 68 (28%) developed the primary outcome. A significant decrease in the incidence of the primary outcome was observed (p < 0.001, r -0.342) during the study period. Anti-Spike monoclonal antibodies (mAbs) were administered as early treatment (within 5-7 days of onset of symptoms) in 101 patients (14 with casirivimab/imdevimab and 87 with sotrovimab). Among 145 patients who had received at least one vaccination dose before infection, 109 patients were considered as adequately vaccinated. Multivariate analysis revealed that the Charlson Comorbidity Index (P 0.001; OR 1.28, CI 1.11-1.48) was associated with the primary outcome, while early administration of mAbs (P 0.032; OR 0.39, CI 0.16-0.92) was associated with a better outcome, but not infection during the period of the omicron variant predominance or adequate vaccination.
