title: A retrospective review of the outcome of plasma exchange and aggressive medical therapy in antibody mediated rejection of renal allografts: a single center experience.
abstract: Antibody-mediated rejection (AMR) has been recognized as a major cause of renal allograft loss. Protocols using plasma exchange (PE) to reverse rejection have mixed results.
  
  
  METHODS
  A retrospective chart review was performed to determine the clinical response to PE inpatients with AMR of renal allograft. A good response to treatment was defined as a decline in serum creatinine (SCr) to within 25% above the prerejection value or discontinuation of dialysis with a SCr <2 mg/dl within 3 months of discharge from the hospital and disappearance of donor-specific alloantibodies (DSA).
  
  
  RESULTS
  Twenty-two patients, treated with PE for biopsy proven AMR with or without acute-cellular rejection (ACR), were included in the study. Sixty-four percent of patients had concurrent AMR and ACR. Fifty-two percent of all patients had a good response to antirejection therapy, whereas 63% of patients with only AMR and 46% of patients with both AMR and ACR had a good response. Good response to PE did not correlate with the number of plasma volumes exchanged (P = 0.09), but correlated with a shorter period from transplantation to the rejection episode (P = 0.002).
  
  
  CONCLUSIONS
  Only a shorter interval between transplantation and the acute rejection episode correlated with a good response to PE.
