Brief summary
This trial seeks to determine if one of 2 currently used treatment regimens for chronic antibody mediated rejection of the renal allograft is superior to the other in terms of preventing chronic damage. The 2 arms include conversion to tacrolimus, mycophenolate and oral prednisolone with pulse methylprednisolone. Arm one has the addition of 3x monthly doses of IVIg. A second round of therapy will be offered if at 3 months a renal biopsy shows ongoing rejection. Chronic damage will be assessed by chronic allograft damage index scores at 12 months.
Interventions
Treatment with intravenous methylprednisolone, 3 doses at 250mg/dose over 3 consecutive days and intravenous immunoglobulin (1gm/kg), 3 doses once per month over 3 months. The above is then repeated after 3 months if there is ongoing active rejection on follow-up biopsy. A further 2 biopsies are preformed at 6 and 12 months. Biopsies entail a local anaesthetic to the skin over the kidney and then passing a 14 gauge needle into the transplant kidney to remove a tiny core of tissue. The participant must stay in a day procedude facility for 4 hours after the procedure to monitor for complications such as bleeding. These are diagnostic procedure and are not therapeutic.
