E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |

|
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The proposed study is aimed to investigate the kinetics and maintenance of CD4+ T cell memory by evaluating VZV-specific CD4+ T cells after two-dose VZV vaccination in RTX recipients compared to two control groups of healthy age-matched children after VZV wildtype infection or after VZV vaccination, prospectively. Additionally, VZV IgG antibody levels and IgG avidity are monitored over 18 months in RTX recipients and healthy age-matched controls to assess humoral immunity against VZV. Main objective: percentage of VZV-specific CD4+ T cells |
|
E.2.2 | Secondary objectives of the trial |
VZV-specific IgG antibodies (U/ml) and relative avidity index of VZV-specific IgG antibodies |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients listed for renal transplantation: Patients with renal failure (meeting the criterias for transplantion listing; renal failure stage 4 or 5, glomerular filtration rate < 29ml/min/1.73m2); age 24 months to 80 years; routine VZV vaccination (Varivax) Healthy subjects (according to WHO definition): age 24 months to 80 years; routine VZV vaccination with Varivax |
|
E.4 | Principal exclusion criteria |
Patients listed for renal transplantation: Positive VZV IgG antibody levels at time point 0; immunosuppression at time of vaccinations; malignancies; rheumatic diseases; loss of immunoglobulins; proteinuria; blood transfusion or treatment with intravenous immunglobulin or plasma products in the last 6 months; pregnancy (validated by urine beta-HCG) Healthy subjects: Positive VZV IgG antibody levels at time point 0; malignancies; rheumatic diseases; immunosuppression; cortisone therapy in the last 6 months; cytostatic therapy; blood transfusion or treatment with intravenous immunglobulin or plasma products in the last 6 months; pregnancy |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Drop-out criteria for vaccination: Transplantation, immunosuppression, wish of patient, wish of doctor Drop-out criteria for blood withdrawal: wish of patient, wish of doctor
