Long-term effects of COVID-19 in solid organ transplantation recipients.

A few months ago, we presented the results from a case-control study evaluating solid organ transplantation (SOT) recipients' outcomes after COVID-19 requiring hospitalization, which showed a trend towards higher mortality among SOT patients compared to controls1 . Other authors reported similar results regarding mortality2 , whereas Chavarto et al. found no increased risk of death among kidney recipients compared to controls3 . We hypothesize that COVID-19 might affect long-term survival of SOT recipients, drug-drug interactions (DDI) might contribute to graft rejection and COVID-19 unknown long-term effects might specially affect immunosuppressed patients4 ; here, we aim to evaluate the long-term outcomes of SOT patients affected by COVID-19.
