Abstract
Desensitization therapy for heart transplantation (HT) candidates can shorten transplant wait times and broaden the donor pool. Specific evidence-based recommendations on both protocols and indications are lacking. We retrospectively assessed left ventricular assist devices-bridged candidates who received pre-HT desensitization therapy. The therapeutic protocol consisted of intravenous immunoglobulin and rituximab followed by bortezomib and plasmapheresis if an insufficient response was achieved. Desensitization was attempted in 10 patients; only 7 tolerated therapy and underwent transplant. For those patients, median decrease in unacceptable calculated panel reactive antibody was 11%; there was no significant decrease for 3 patients. Post-desensitization adverse events were observed in all patients which included coagulopathy, bone marrow suppression, and infection. Median time to first infection was 16 days. One patient had clinically significant rejection and 3 patients had uptrending donor-specific antibodies. Decisions to proceed with desensitization should be individualized understanding potential risks and benefits.
