Desensitization of Highly Sensitized Deceased Donor Renal Transplantation Candidates
Some patients who need kidney transplants have high levels of antibodies that make them incompatible with most potential deceased donor kidney offers. These patients are considered highly-sensitized and are very difficult to transplant because the likelihood that they will receive a compatible organ is very low. There are some medications and procedures that can decrease the antibody levels and this can increase the chance of finding a compatible donor for these patients. In this study the investigators will give two medications (IVIg and Rituximab) to highly-sensitized patients who are on the waiting list for a deceased donor kidney transplant. After the investigators administer these medications, the investigators will continue to check for compatibility as organ offers are received. If a compatible organ offer is received, the investigators will perform the transplant using that organ. The investigators hypothesize that these medications will lower antibody levels and increase the chance that a these patients are able to receive a compatible kidney transplant.

- Time to kidney transplantation [ Time Frame: 4 months ] [ Designated as safety issue: No ]
- Decrease in panel reactive antibody [ Time Frame: 4 months ] [ Designated as safety issue: No ]
|Study Start Date:||September 2009|
|Study Completion Date:||July 2011|
|Primary Completion Date:||July 2011 (Final data collection date for primary outcome measure)|
Drug: IVIg and rituximab
A maximum of four doses (each single dose being 2gm/kg) of IVIg will be administered over a four-month period, with one dose administered each month. Each single dose of 2gm/kg will be administered in two half-doses (1gm/kg each) to be given one day apart, with one day of hemodialysis on the intervening day between the two half-doses.
If a compatible kidney transplant organ offer is received, upon admission to the hospital and immediately prior to the transplant operation, patients will receive a single infusion of Rituximab (375 mg/m2 BSA).
