Brief Summary

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

To investigate the variations in the humoral response to vaccines for the prevention of COVID-19 in liver transplant patients based on the type of immunosuppressive therapy adopted (tacrolimus based vs no-tacrolimus based) and immunosuppressive blood levels.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

tacrolimus-based immunosuppresion

The TAC-based group will include any patient on tacrolimus monotherapy and patients taking multiple IS medications with blood tacrolimus levels \> 5 ng/mL

Immunoassay, by ECLIA, for the quantitative in vitro determination of antibodies (including IgG) to the SARS - CoV - 2 spike protein (S) anti-RBD (receptor-binding domain) in serum and plasma samples.

Intervention Type DIAGNOSTIC_TEST

Blood test to value the antibody response to vaccination

NON-tacrolimus-based immunosuppresion

The NON-TAC-based group will include any patient on TAC-free therapy and patient taking multiple IS medications with blood tacrolimus levels \< 5 ng/mL

Immunoassay, by ECLIA, for the quantitative in vitro determination of antibodies (including IgG) to the SARS - CoV - 2 spike protein (S) anti-RBD (receptor-binding domain) in serum and plasma samples.

Intervention Type DIAGNOSTIC_TEST

Blood test to value the antibody response to vaccination
