Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to evaluate the immune response after COVID-19 vaccination in Liver(LT) and Kidney(KT) transplant recipient. The main question it aims to answer are:

* the evaluation of the antibody response after complete vaccination
* the efficacy of prophylaxis with long-acting-antibody prophylaxis (LAAB)

All LT and KT patients during follow-up have been enrolled. anti-COVID-19 title was obtained by Electrochemiluminescence Immunoassay (ECLIA) Test(Elyx, Roche). In the case of antibody level \<100 IU/ml, patients were invited to prophylaxis with tixagevimab-cilgavimab(AZD7442, AstraZeneca). At three months, a follow-up was performed to assess any COVID-19 infection. At Six months another anti-COVID-19 title is obtained by ECLIA Test(Elyx, Roche) in LT and KT who undergo to LAAB.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Liver(LT) and kidney(KT) transplant patients are at high risk of mortality from COVID-19(16-29%, 28%; respectively). Although transplant patients undergo a full vaccination course(3 doses), they are frequently low-responders and long-acting-antibody prophylaxis (LAAB) has been proposed. However, the efficacy of these strategies has not yet been demonstrated in LT and KT.

Kidney and Liver Transplant

All Kidney and Liver Transplant recipients who are at follow-up in our institution will be enrolled. anti-COVID-19 title was obtained by ECLIA Test(Elyx, Roche). In the case of antibody level \<100 IU/ml, patients were invited to prophylaxis with tixagevimab-cilgavimab(AZD7442, AstraZeneca). At three months, a follow-up was performed to assess any COVID-19 infection.
