Information source: University of Giessen
Information obtained from ClinicalTrials.gov on June 20, 2008
Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Renal Failure, Chronic; Renal Transplantation

Intervention: intravenous immunoglobulins (IVIG) (Drug); kidney transplantation (Procedure)

Phase: N/A

Status: Completed

Sponsored by: University of Giessen

Official(s) and/or principal investigator(s):
Rolf Weimer, Prof. Dr., Principal Investigator, Affiliation: Department of Internal Medicine, University of Giessen, Giessen, Germany

Summary

The aim of this randomized prospective study in renal transplant recipients is to investigate immunological short and long-term effects of an IVIG induction therapy.

Furthermore clinical endpoints (patient and graft survival, incidence of acute and chronic rejection, infectious diseases and graft function) up to three years posttransplant will be analyzed.

Clinical Details

Official title: Immunoglobulin Induction Therapy in Renal Transplant Recipients on Tacrolimus/Azathioprine or Tacrolimus/MMF: Effects on Th1, Th2, B Cell-/Monokine Responses and Immunoregulatory Autoantibody Levels

Study design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Efficacy Study

Primary outcome:

patient survival

graft survival

acute rejection

chronic allograft nephropathy

Secondary outcome:

graft function

infectious complications

immunoglobulin levels

regulatory autoantibody levels

Th1 and Th2 responses

B-cell/monocyte responses

Expression of adhesion molecules, costimulatory molecules and cytokine receptors

proteinuria (quantitative assessment)

Detailed description: Intravenous immunoglobulin (IVIG) preparations are known to be effective in the treatment of various autoimmune and inflammatory disorders due to their immunomodulatory and antiinflammatory properties. It has been demonstrated that IVIG is effective in the treatment of acute vascular rejection and steroid resistant cellular rejection. Furthermore, IVIG has been used to inhibit production of lymphocytotoxic antibodies in highly sensitized patients so that successful cadaveric or living renal transplantation could be performed.

The aim of this randomized prospective study in renal transplant recipients is to investigate immunological short and long-term effects of an IVIG induction therapy on Th1, Th2 and B-cell/monocyte responses, expression of adhesion molecules, costimulatory factors and cytokine receptors and on secretion of immunoregulatory autoantibodies (anti-F(ab)-, anti-F(ab')2G-, anti-hinge autoantibodies). These autoantibodies have been shown to significantly affect the risk of chronic rejection and graft loss.

Furthermore, clinical endpoints (patient and gaft survival, incidence of acute and chronic rejection, infectious diseases and graft function) up to 3 years will be analyzed.
