Similar risk of hospitalization and lethality from COVID-19 in transplant recipients and waitlisted patients: A...

In 2022, Spanish health authorities recommended passive immunisation against COVID-19 for solid organ transplant recipients (SOT), due to their deficient post-vaccination humoral response. Patients on the transplant waiting list (SOTwl) were excluded from this strategy.

To compare the risk of hospitalisation, ICU admission, and mortality due to COVID-19 between SOT and SOTwl patients.

Patients seen in the Preventive Medicine Department at Ramón y Cajal Hospital between 03/14/2020 and 04/13/2022. The relative risk (RR) of hospitalisation, ICU admission, and mortality was estimated among SOT and SOTwl patients, adjusted for age, sex, and vaccine doses.

A total of 1292 patients were analyzed. SOT patients (n=1153) were older and had similar risks of hospitalisation (RR 0.97, 95% CI 0.57-1.64), ICU admission (RR 1.74, 95 % CI 0.44-6.86), and death (RR 0.89, 95% CI 0.45-1.77) compared to SOTwl patients (n=139).

The risks of hospitalisation, ICU admission, and mortality were similar between SOT and SOTwl patients.
