Immunomonitoring by virus-specific T cells and evaluation as a prognostic marker for virus-induced diseases after kidney transplantatio
- Conditions
- After solid organ transplantation immunosuppressive treatment disrupts the individual balance between virus-replication and cellular immune response. This can lead to an elevated risk of severe viral complications.1) Immunosuppressive therapy might better be steered by measuring of virus-specific T cells than by blood levels of immunosuppressants solely.2) The antiviral treatment should be restricted to patients with high risk of viral diseases (high costs, severe side effects).MedDRA version: 19.1Level: PTClassification code 10052279Term: Renal and liver transplantSystem Organ Class: 10042613 - Surgical and medical procedures

1.Patients who are males or non-pregnant females between the ages of 0 and 16 years.
2.Patients after kidney transplantation.
3.Patients who receive their first or second transplantation.
4.Patients who are single-organ recipients.
5.If patients are women of childbearing potential, they must have a negative serum pregnancy test with a sensitivity equal to at least 50 mIU/ml before transplantation.
6.If patients are women of childbearing potential, they must use an effective form of contraception like birth control pill (except mini pill), hormonal depot injection, contraceptive hormonal patches, implanon, contraceptive hormone containing coil or hormon containing contraceptive vaginal ring, unless abstinence is the chosen method. In case of medical contraindication concerning the hormonal contraception, an intrauterine coil with a second contraceptive method (sondom, diaphragm, spermicide) can be used. Effective contraception must be used before transplantation, during therapy and for 6 weeks following discontinuation og immunosuppressive therapy.
7.Patients’ guardians must be capable of understanding the purpose and risks of the study.
8.Patients whose guardians are willing to give written informed consent and willing to participate in and comply with the study protocol. Patients above 7 years have to agree with the study in addition to the informed consent of the legally authorized representative.

5.Patients from other centers, who are not followed in the outpatient unit of the Hannover Medical School or corresponding recruiting centers.
6.Patients with a peak or current PRA of >50%.
7.Pregnant and/or lactating women and women of childbearing potential who are unwilling or unable to use contraception methods as specified.

11.Patients who are not eligible in the opinion of the physician.
12.Significant medical history and/or treatments for cardiac, renal, neurological, hepatic, endocrine diseases, or any laboratory abnormality indicative of a significant underlying condition, that may interfere with patient’s safety, compliance, or study evaluations, according to the investigator’s opinion.
