Histological features of Cyclosporine Nephrotoxicity


The objectives of CNI sparing protocols:

To reduce CNI nephrotoxicity and chronic graft injury: and thereby– improve renal graft function– reduce overall toxicity– improve long-term graft survival

But maintain efficacy in terms of

acute and subclinical rejection

Desensitization Protocols


Approaches to Desensitization

Mark D. Stegall, M.D.Mayo Clinic, Rochester, MN

ASN Renal Week November 7, 2008


DesensitizationWhat is it?• Removing or blocking donor specific antibody (almost

always anti-HLA)• High Dose IVIG versus low dose IVIG and plasmapheresis

with or without rituximabGoal?Prevention of: • Hyperacute rejection • Acute humoral rejection• Transplant glomerulopathy (chronic damage)Efficacy?• Few comparative studies of different approaches


IVIG + Rituximab Protocol Vo et al NEJM 2008;359:242-51

• 20 sensitized patients underwent IVIG desensitization

• IVIG 2 g/kg day 0, 30 and Rituximab 1g on day 7 and 22)

• Required a T cell AHG – at 1:2 and a T flow crossmatch <250.

• 18 transplanted (8 deceased donor and 10 living donor)

• Alemtuzumab, Tacrolimus, MMF, Pred


IVIG and Acute Rejection

• Acute rejection• 50%• 31% C4d+ AMR• Treatment• Banff I or II: methylprednisolone, IVIG (2

g/kg) and rituximab (375 mg/BSA) • Banff III: Plasmapheresis (3-5 sessions)

IVIG and rituximab (375 mg/BSA)

• IVIg and Plasmapheresis:• “The azathioprine and prednisone

of desensitization”:• Major Problem: Current protocols do not

control antibody production• Solution: We need to understand

antibody production better• New Paradigms

• Prevent antibody production• Prevent the impact of antibody

(complement inhibition)


Proteasome Inhibition

• Proteasome is a group of enzymes that “recycles” proteins in eukaryotic cells

• Very active in highly-secretory cells• Velcade (bortezomib)—FDA approved

proteasome inhibitor approved for treatment of resistant myeloma

• Kills by apoptosis

• Humanized monoclonal antibody• FDA approved for treatment of paroxysmal

• ½ life = ??• Partially removed by plasmapheresis


Anti-C5 Study • Combine anti-C5 Ab with current

• Expected Findings: • High antibody levels (and C4d+) without

Deceased Donor Types: SCD, DCD, ECD & DCD-ECD Heart-beating (primary brain death)

1. SCD: Standard Criteria Donor● Heart-beating donors● Less than 60 years of age and not

2. ECD: Expanded Criteria Donor● Heart-beating donors over 60 years of age or those

between age 50 and 59 year plus two of the following three conditions: died of a stroke, had a history of hypertension, or had a terminal serum creatinine of greater than 1.5

Non-heart beating (cardiac standstill precedes/simultaneous with brain death)3. DCD: Donation After Cardiac Death
