RESUMO

We tested the synergy of donor-specific transfusion (DST) and cyclosporine (CsA) in small bowel transplantation by comparing the systemic versus portal route of DST administration in a fully allogeneic rat model. The protocol is relevant to cadaveric transplantation by conditioning only 24 hr before allografting. A 1 ml intraportal DST day -1 and low-dose CsA significantly prolonged survival (MST 53.7 +/- 17.5 days) when compared with systemic DST day -1 and low-dose CsA (MST 18.4 +/- 5.6 days). This suggests that intraportal DST can be beneficial in cadaveric SBT, as only a 24-hr induction period is necessary. We speculate that antigen trapping in the liver and interaction of the DST with Kupffer cells is central to the portal DST effect.

RESUMO

The case of patient with glioblastoma metastatic to the peritoneal cavity 9 months after ventriculoperitoneal shunt surgery precluding cadaver organ procurement is presented. Even though central nervous tumors rarely metastasize spontaneously, the literature indicates that systemic metastases are related to previous surgical procedures and especially shunt surgery. Central nervous tumors have been known to metastasize to lungs, liver, and kidneys and could be transmitted through transplanted organs as shown in the Cincinnati tumor registry. The transplant surgeon should be alerted to this possibility and thorough search for metastases should be undertaken before considering primary brain tumor patients as donors.
