Predicting renal graft failure by sCD30 levels and de novo HLA antibodies at 1year post-transplantation.

HLA antibodies and sCD30 levels were detected in the serum sampled from 620 renal graft recipients at 1 year post-transplantation, which were followed up for 5 years. Six-year graft and patient survivals were 81.6% and 91.0%. HLA antibodies were detected in 45 recipients (7.3%), of whom there were 14 cases with class I antibodies, 26 cases with class II, and 5 cases with both class I and II. Much more graft loss was record in recipients with HLA antibodies than those without antibodies (60% vs. 15.1%, p<0.001). Significantly higher sCD30 levels were recorded in recipients suffering graft loss than the others (73.9±48.8 U/mL vs. 37.3±14.6 U/mL, p<0.001). Compared with those with high sCD30 levels, recipients with low sCD30 levels (<50 U/mL) had much better 6-year graft survival (92.4% vs. 46.6%, p<0.001). Further statistical analysis showed that detrimental effect of de novo HLA antibodies and high sCD30 on graft survival was not only independent but also additive. Therefore, post-transplantation monitoring of HLA antibodies and sCD30 levels is necessary and recipients with elevated sCD30 level and/or de novo HLA antibody should be paid more attention in order to achieve better graft survival (read more) Print this post
